PRELIMINARY — Subject to Completion, dated August 4, 2020

PROPOSED MERGER TRANSACTION — YOUR VOTE IS VERY IMPORTANT

To the stockholders of Liquidia Technologies, Inc.:

You are cordially invited to attend the special meeting of the stockholders of Liquidia Technologies, Inc., a Delaware corporation, which we refer to as Liquidia Technologies, which will be held at , Eastern Time, on , 2020. Due to concerns regarding the novel coronavirus, or COVID-19, pandemic and to protect the health and safety of our employees and stockholders, the special meeting will be a virtual meeting conducted solely online via live webcast and can be attended by visiting www.meetingcenter.io/ . If you plan to attend the meeting virtually on the Internet, you must register by following the instructions contained in the Voting Procedures section of this proxy statement/prospectus. In connection with the special meeting, you will be asked to consider and vote on certain stockholder proposals which are more fully described below and in the accompanying proxy statement/prospectus. Whether or not you plan to virtually attend the special meeting, we urge you to read the proxy statement/prospectus (and any documents exhibited to the proxy statement/prospectus or incorporated into the proxy statement/prospectus by reference) and consider such information carefully before voting. This is an important special meeting that affects your investment in Liquidia Technologies.

Liquidia Technologies has agreed to acquire RareGen, LLC, which we refer to as RareGen, under the terms of an Agreement and Plan of Merger, dated as of June 29, 2020, or the Merger Agreement. If this acquisition is completed, Liquidia Technologies and RareGen will become subsidiaries of a new holding company named Liquidia Corporation, which we refer to as HoldCo. We refer to the acquisition of RareGen by Liquidia Technologies, after which RareGen and Liquidia Technologies will operate as subsidiaries of HoldCo, pursuant to the Merger Agreement, as the Merger Transaction. We are proposing the Merger Transaction because we believe that the combined company will create more stockholder value than Liquidia Technologies could individually.

If the Merger Transaction is completed, (i) each share of our common stock, $0.001 par value per share, or Liquidia Technologies common stock, whether certificated or held in book-entry form, will automatically convert into one share of HoldCo common stock, $0.001 par value per share, or HoldCo common stock, (ii) each option and warrant to purchase a share of our common stock will entitle the holder to purchase one share of HoldCo common stock, and the exercise price per share will be identical to the Liquidia Technologies option or warrant, and (iii) each Liquidia Technologies restricted stock unit will entitle the holder to a HoldCo restricted stock unit, each to vest and settle into a share of HoldCo common stock.

If the Merger Transaction is completed, RareGen members will receive an aggregate of 6,166,666 shares of HoldCo common stock upon closing of the Merger Transaction, including 616,666 shares of HoldCo common stock which will be withheld from RareGen members to secure the indemnification obligations of RareGen members, which we refer to as the Holdback Shares. RareGen members will be entitled to receive, on a pro rata basis, any Holdback Shares remaining on March 31, 2022. Additionally, RareGen members shall be entitled to a pro rata portion of any RareGen cash at closing in excess of $1 million. RareGen members will also be entitled to receive a pro rata portion of up to an additional 2,708,333 shares of HoldCo common stock in the aggregate in 2022, based on the amount of 2021 net sales of the generic treprostinil product owned by Sandoz Inc., or Sandoz, which RareGen markets pursuant to a Promotion Agreement between the parties. For more information, see “Proposal 1 — The Merger Transaction: The Merger Consideration and Conversion of Securities” on page 110.

Upon closing of the Merger Transaction:

•

the holders of our common stock, options, warrants and restricted stock units (excluding, for this purpose, shares of HoldCo common stock to be received by current RareGen members, or known affiliates of RareGen members, who are holders of our common stock) will receive, in the aggregate, approximately 86.0% of the HoldCo common stock outstanding at the closing of the Merger Transaction on a fully diluted basis;

TABLE OF CONTENTS

•

the holders of RareGen common units will receive, in the aggregate, approximately 14.1% of the HoldCo common stock outstanding at the closing of the Merger Transaction (with the contingent right to receive up to an additional approximately 6.3% of HoldCo common stock outstanding at the closing of the Merger Transaction based on the amount of 2021 net sales of the generic treprostinil product owned by Sandoz and marketed by RareGen) assuming, solely for this purpose, that the RareGen members receive all of the Holdback Shares.

We encourage you to read the section of this proxy statement/prospectus entitled “Proposal 1 — The Merger Transaction: The Merger Consideration and Conversion of Securities” beginning on page 110 carefully, as it explains how our and RareGen’s equity is converted into HoldCo common stock.

Our common stock is currently traded on the Nasdaq Capital Market under the trading symbol “LQDA.” RareGen common units are privately held and are not publicly traded. After the Merger Transaction, our common stock will no longer be traded on the Nasdaq Capital Market and HoldCo common stock is expected to be traded on the Nasdaq Capital Market under the trading symbol “LQDA” as the successor to Liquidia Technologies.

Our stockholders are also being asked to vote on certain other matters related to the Merger Transaction, including the approval of the Liquidia Corporation 2020 Long-Term Incentive Plan, which we refer to as the HoldCo 2020 Incentive Plan, the approval of the Liquidia Corporation 2020 Employee Stock Purchase Plan, which we refer to as the HoldCo 2020 ESPP, and the grant to our board of directors of discretionary authority to adjourn or postpone the special meeting to a later date, if necessary, to solicit additional proxies if there are insufficient votes in favor of Proposals 1, 2, 3 or 4.

Upon the recommendation of our board of directors, our board of directors has approved and declared the advisability of the Merger Agreement, the Liquidia Merger and the Merger Transaction, and recommends that our stockholders vote “FOR” adoption of the Merger Agreement and approval of the merger of Liquidia Technologies with Gemini Merger Sub I, Inc., “FOR” approval of the HoldCo 2020 Incentive Plan, “FOR” approval of the HoldCo 2020 ESPP and “FOR” the grant of discretionary authority to our board of directors to adjourn or postpone the special meeting to a later date. Before voting, you should carefully review all the information contained in this proxy statement/prospectus. In particular, you should carefully consider the matters discussed under the section entitled “Risk Factors” beginning on page 36, including certain risks and uncertainties resulting from the Merger Transaction.

On the pages after this letter, you will find the notice of the special meeting, which lists the matters to be considered at the special meeting, and the proxy statement/prospectus, which describes the matters listed in the notice.

Your vote at this special meeting is very important. Whether or not you plan to virtually attend the special meeting, I hope you will vote as soon as possible. If you are a stockholder of record, you may vote over the Internet or by telephone. You will find voting instructions in the notice and proxy statement/prospectus and on the proxy card. If your shares are held in “street name” — that is, held for your account by a broker or other nominee — you will receive instructions from the holder of record that you must follow for your shares to be voted.

On behalf of the Board of Directors, I thank you for your continued support of Liquidia.

Yours Sincerely,

/s/ Neal F. Fowler

Chief Executive Officer and Director

				• By Mail. You will receive instructions from your broker or other nominee explaining how to cast your vote.

TABLE OF CONTENTS

				If your shares are held in “street name,” your brokerage firm, under certain circumstances, may vote your shares for you if you do not return your proxy. Brokerage firms have authority to vote customers’ unvoted shares on matters that the New York Stock Exchange, or NYSE, determines to be “routine.” If you do not give a proxy to your brokerage firm to vote your shares, your brokerage firm may either: vote your shares on routine matters, or leave your shares unvoted. Each of the proposals which you are being asked to vote on are not considered routine matters except for Proposal 4, the ratification of the independent registered public accounting firm. We therefore strongly encourage you to provide voting instructions to your brokerage firm by submitting your proxy. This ensures your shares will be voted at the meeting according to your instructions. You should receive directions from your brokerage firm about how to submit your proxy to them.
	IF I DO NOT GIVE INSTRUCTIONS TO MY BANK OR BROKER, WHAT MATTERS DOES MY BANK OR BROKER HAVE AUTHORITY TO VOTE UPON?			Pursuant to NYSE Rule 452 and corresponding Listed Company Manual Section 402.08, discretionary voting by brokers of shares held by their customers in “street name” is prohibited. If you do not give instructions to your bank or broker within ten days of the special meeting, it may vote on matters that the NYSE determines to be “routine,” but will not be permitted to vote your shares with respect to “non-routine” items. Under the NYSE rules, each of the proposals which you are being asked to vote on are non-routine matters except for Proposal 4, the ratification of the independent registered public accounting firm. When a bank or broker has not received instructions from the beneficial owners or persons entitled to vote and the bank or broker cannot vote on a particular matter because it is not routine, then there is a “broker non-vote” on that matter. Broker non-votes will be counted in determining whether there is a quorum for the special meeting. As a result, we strongly encourage you to submit your voting instructions and exercise your right to vote as a stockholder.
	WHAT DOES IT MEAN IF I RECEIVE MORE THAN ONE PROXY CARD?			It means that you have more than one account, which may be at the transfer agent, with stockbrokers or otherwise. Please vote over the Internet, or complete and return all proxies for each account to ensure that all of your shares are voted.
	HOW MANY SHARES MUST BE PRESENT TO HOLD THE MEETING?			A majority of our outstanding shares of common stock as of the Record Date must be present at the special meeting to hold the special meeting and conduct business. This is called a quorum. Shares are counted as present at the special meeting if the stockholder votes over the Internet or telephone, completes and submits a proxy or is virtually present at the special meeting. Shares that are present that vote to abstain or do not vote on one or more of the matters to be voted upon are counted as present for establishing a quorum. If a quorum is not present, we expect that the special meeting will be adjourned until we obtain a quorum.

	WHAT VOTE IS REQUIRED TO APPROVE EACH MATTER AND HOW ARE VOTES COUNTED?			Proposal 1 — Approval of the Merger Agreement and the Liquidia Merger To approve Proposal 1, if a quorum is present or represented by proxy at the special meeting, stockholders holding a majority of our common stock outstanding and entitled to vote on the matter must vote “FOR” the proposal, meaning that the votes cast by the stockholders “FOR” the approval of the proposal must equal a majority of the shares outstanding. If a stockholder votes to “ABSTAIN,” it has the same effect as a vote “AGAINST.” Broker non-votes will have the same effect as a vote “AGAINST” this proposal. If no vote is specified on the proxy and in the absence of directions to the contrary, the shares will be voted “FOR” the Merger Agreement and the Liquidia Merger.
				Proposal 2 — Approval of the HoldCo 2020 Incentive Plan
				To approve Proposal 2, if a quorum is present or represented by proxy at the special meeting, stockholders holding a majority of our common stock present or represented by proxy at the special meeting and entitled to vote on the matter must vote “FOR” the proposal, meaning that the votes cast by the stockholders “FOR” the approval of the proposal must exceed the number of votes cast “AGAINST” the approval of the proposal. If a stockholder votes to “ABSTAIN,” it has the same effect as a vote “AGAINST.” Broker non-votes will not be considered as votes cast “FOR” or “AGAINST” this proposal and will therefore have no effect on the outcome of the vote. If no vote is specified on the proxy and in the absence of directions to the contrary, the shares will be voted “FOR” the HoldCo 2020 Incentive Plan.
				Proposal 3 — Approval of the HoldCo 2020 ESPP
				To approve Proposal 3, if a quorum is present or represented by proxy at the special meeting, stockholders holding a majority of our common stock present or represented by proxy at the special meeting and entitled to vote on the matter must vote “FOR” the proposal, meaning that the votes cast by the stockholders “FOR” the approval of the proposal must exceed the number of votes cast “AGAINST” the approval of the proposal. If a stockholder votes to “ABSTAIN,” it has the same effect as a vote “AGAINST.” Broker non-votes will not be considered as votes cast “FOR” or “AGAINST” this proposal and will therefore have no effect on the outcome of the vote. If no vote is specified on the proxy and in the absence of directions to the contrary, the shares will be voted “FOR” the HoldCo 2020 ESPP.

				Proposal 4 — Ratify the Appointment of PricewaterhouseCoopers LLP as HoldCo’s Independent Registered Public Accounting Firm for the Year Ending December 31, 2020
				To approve Proposal 4, if a quorum is present or represented by proxy at the meeting, stockholders holding a majority of our common stock present or represented by proxy at the special meeting and entitled to vote on the matter must vote “FOR” the proposal, meaning that the votes cast by the stockholders “FOR” the approval of the proposal must exceed the number of votes cast “AGAINST” the approval of the proposal. If a stockholder votes to “ABSTAIN,” it has the same effect as a vote “AGAINST.” As Proposal 4 is a routine matter, broker non-votes will not occur with respect to this proposal. If no vote is specified on the proxy and in the absence of directions to the contrary, the shares will be voted “FOR” the ratification of the appointment of HoldCo’s independent auditor.
				The inspector of election appointed for the special meeting, who will separately tabulate affirmative and negative votes, abstentions and broker non-votes, will tabulate all votes.

QUESTIONS AND ANSWERS ABOUT THE MERGER TRANSACTION

Q: Why am I receiving this proxy statement/prospectus?

A: We and RareGen have agreed that we will acquire RareGen under the terms of an Agreement and Plan of Merger, referred to herein as the Merger Agreement, that is described in this proxy statement/prospectus. A copy of the Merger Agreement is attached to this proxy statement/prospectus as Annex A. You are receiving this proxy statement/prospectus because we are asking our stockholders to adopt the Merger Agreement and approve the Liquidia Merger. Neither we nor RareGen are soliciting votes of RareGen’s members in this proxy statement/prospectus.

In connection with the Merger Transaction, our stockholders are also being asked to approve the HoldCo 2020 Incentive Plan and the HoldCo 2020 ESPP and ratify the appointment of HoldCo’s independent auditor for 2020. Copies of the HoldCo 2020 Incentive Plan and the HoldCo 2020 ESPP are attached to this proxy statement/prospectus as Annex C and Annex D, respectively. This proxy statement is also a prospectus provided by Liquidia Corporation, which we refer to as HoldCo, in connection with HoldCo’s offer of its common stock to be issued upon completion of the Merger Transaction.

We will hold a special meeting of our stockholders to obtain the necessary stockholder approvals. This proxy statement/prospectus contains important information about the proposed Merger Transaction and the special meeting of our stockholders. You should read this proxy statement/prospectus carefully.

Your vote is important. We encourage you to vote as soon as possible.

Q: Why are we proposing the Merger Transaction?

A: We believe that the combination of the two companies will provide substantial strategic and financial benefits to our stockholders by creating a stronger company primarily focused on the treatment of pulmonary arterial hypertension, or PAH, that is capable of creating more equityholder value than either we or RareGen could individually. Additionally, the combined company will have a scalable PAH commercial infrastructure, it will have experience with PAH commercial launches and the onboarding of PAH experts currently at RareGen to HoldCo’s management and board of directors will serve to fortify the combined company’s PAH expertise. Further, the Merger Transaction also results in immediate cash flow to HoldCo through sales of generic treprostinil via RareGen’s Promotion Agreement, dated as of August 1, 2018, as amended, with Sandoz Inc., or Sandoz, which we refer to herein as the Promotion Agreement. While the Merger Transaction has the potential to create greater value for our stockholders, please see the section entitled “Risk Factors” beginning on page 36 for more information on the risks associated with the Merger Transaction and the business of HoldCo following the Merger Transaction, among other risks. To review our reasons for the Merger Transaction, including specific risks considered by our board of directors in greater detail, see the section entitled “Proposal 1 — The Merger Transaction: Liquidia’s Reasons for the Merger Transaction” beginning on page 95 and “Proposal 1 — The Merger Transaction: RareGen’s Reasons for the Merger Transaction” beginning on page 97.

Q: Does our board of directors recommend voting in favor of the Merger Agreement?

A: Yes. After careful consideration, upon the recommendation of the transaction committee of our board of directors, which we refer to as the transaction committee, our board of directors determined that the Merger Transaction is advisable and is fair to, and in the best interests of, our company and our stockholders. Our board of directors recommends that our stockholders vote “FOR” the adoption of the Merger Agreement and approval of the Liquidia Merger.

For a description of the factors considered by our board of directors in making its determination, see the section entitled “Proposal 1 — The Merger Transaction: Liquidia’s Reasons for the Merger Transaction” beginning on page 95.

Q: What will happen in the Merger Transaction?

A: In order to combine the Liquidia Technologies and RareGen businesses, we formed a new holding company, Liquidia Corporation, with two subsidiaries, Liquidia Merger Sub and RareGen Merger Sub. At the effective time of the Merger Transaction, RareGen Merger Sub will merge with and into

TABLE OF CONTENTS

RareGen, with RareGen surviving the merger as a subsidiary of HoldCo. We refer to this merger as the RareGen Merger. Immediately following the RareGen Merger, an additional merger will occur in which Liquidia Merger Sub will merge with and into Liquidia Technologies, with Liquidia Technologies surviving the merger as a subsidiary of HoldCo. We refer to this merger as the Liquidia Merger. As a consequence of these mergers, Liquidia Technologies and RareGen will each become a subsidiary of HoldCo, and equityholders of Liquidia Technologies and RareGen will become stockholders of HoldCo. We refer to the entire transaction as the Merger Transaction.

Q: What will happen to Liquidia Technologies if, for any reason, the merger with RareGen does not close?

A: We have invested significant time and incurred, and expect to continue to incur, significant expenses related to the proposed Merger Transaction. Although our board of directors may elect to, among other things, attempt to complete another strategic transaction, such as the potential formation of a partnership or a licensing transaction with respect to our lead program, LIQ861, for the treatment of PAH, if the Merger Transaction does not close, we will continue to work toward achieving regulatory approval and subsequent commercialization of LIQ861.

Q: What will Liquidia Technologies and RareGen equityholders receive in the Merger Transaction?

A: Upon the closing of the Merger Transaction, (i) each share of our common stock, whether certificated or held in book-entry form, will automatically convert into one share of HoldCo common stock, (ii) each option or warrant to purchase our common stock will convert into an option or warrant to purchase an identical number of shares of HoldCo common stock as are underlying such Liquidia Technologies option or warrant, and the exercise price per share will be identical to the Liquidia Technologies option or warrant and (iii) each Liquidia Technologies restricted stock unit will entitle the holder to a HoldCo restricted stock unit, which upon vesting, will settle into a share of HoldCo common stock. Therefore, based on shares of our common stock outstanding as of , 2020, our stockholders will receive, in the aggregate, a total of shares of HoldCo common stock, or approximately % of the HoldCo common stock outstanding at the closing of the Merger Transaction (which, for the avoidance of doubt, includes the Holdback Shares but excludes the Net Sales Earnout Shares, as discussed below), and holders of our common stock, options and warrants to purchase shares of our common stock and our restricted stock units will receive, in the aggregate, a total of shares of HoldCo common stock, or approximately % of the HoldCo common stock at the closing of the Merger Transaction, on a fully diluted basis.

Example: If a Liquidia Technologies stockholder owns 10,000 shares of our common stock and an option to purchase 1,000 shares of our common stock, then as a result of the Merger Transaction, the stockholder will receive 10,000 shares of HoldCo common stock and an option to purchase 1,000 shares of HoldCo common stock.

Upon the closing of the Merger Transaction, all 10,000 RareGen common units, representing all of the issued and outstanding RareGen equity, will convert into the right to receive an aggregate of 6,166,666 shares of HoldCo common stock, including 616,666 shares of HoldCo common stock which will be withheld from RareGen members to secure the indemnification obligations of RareGen members, which we refer to as Holdback Shares. RareGen members will be entitled to receive, on a pro rata basis, any Holdback Shares remaining on March 31, 2022. Additionally, RareGen members shall be entitled to a pro rata portion of any RareGen cash at closing in excess of $1.0 million. RareGen members will also be entitled to receive up to an additional 2,708,333 shares of HoldCo common stock in the aggregate, based on the amount of 2021 net sales of the generic treprostini product owned by Sandoz which RareGen markets pursuant to a Promotion Agreement between the parties. See “Under what circumstances, and when, will RareGen members receive additional HoldCo shares or other consideration following the closing of the Merger Transaction?” below.

Example: If a RareGen member owns 75 common units, then as a result of the Merger Transaction, the RareGen member will be entitled to receive 41,625 shares of HoldCo common stock and its pro rata portion of any RareGen cash in excess of $1.0 million at the closing of the Merger Transaction, and will be entitled to receive up to 4,625 Holdback Shares on or about March 31, 2022 and up to 20,312 Net Sales Earnout Shares in 2022, based on the amount of net sales of Sandoz’s generic treprostinil product in 2021.

TABLE OF CONTENTS

See “Under what circumstances, and when, will RareGen members receive additional HoldCo shares or other consideration following the closing of the Merger Transaction?” below for more information.

Q: How will warrants, stock options and restricted stock units be affected by the Merger Transaction?

A: Each outstanding warrant and option to purchase our common stock, and each restricted stock unit, will be assumed by HoldCo at the effective time of the Merger Transaction on a one-for-one basis. HoldCo will assume each outstanding award under the Liquidia Technologies, Inc. Stock Option Plan, as amended, the Liquidia Technologies, Inc. 2016 Equity Compensation Plan, as amended, and the Liquidia Technologies, Inc. 2018 Long-Term Incentive Plan, which we collectively refer to herein as the Liquidia Equity Plans. Each assumed award will continue to have, and be subject to, the same terms and conditions set forth in the applicable foregoing plans, except as noted below. RareGen does not have any outstanding options.

Each option and warrant to purchase shares of our common stock outstanding immediately prior to the effective time of the Merger Transaction will become an option or warrant to purchase shares of HoldCo common stock, with an identical exercise price per share. Each Liquidia Technologies restricted stock unit will become a HoldCo restricted stock unit. Each assumed Liquidia Technologies option and restricted stock unit will be vested as to the same percentage of the total number of shares as it was vested immediately prior to the effective time of the Merger Transaction. No consent of our option holders, warrant holders or restricted stock unit holders is needed to effect the assumption of such derivative securities by HoldCo. Each outstanding warrant to purchase our common stock will be assumed by HoldCo at the effective time of the Merger Transaction. Each assumed Liquidia Technologies warrant will be exercisable for a like number of shares of HoldCo common stock with an identical exercise price per share as such Liquidia Technologies warrant.

For more information about how our stock options, warrants and restricted stock units will be affected by the Merger Transaction, see the section entitled “Proposal 1 — The Merger Transaction: Treatment of Stock Options, Warrants and Restricted Stock Units” beginning on page 113.

Q: What are the differences between Liquidia Corporation and Liquidia Technologies?

A: As Liquidia Technologies’ successor following the closing of the Merger Transaction, the certificate of incorporation and bylaws of HoldCo are substantially identical to the amended and restated certificate of incorporation, as amended, and the amended and restated bylaws of our company. The only changes between the governing documents of our company and HoldCo are (i) the company name, (ii) the number of shares of HoldCo common stock authorized under the HoldCo certificate of incorporation (80,000,000 shares) versus the number of shares of our common stock currently authorized under our amended and restated certificate of incorporation, as amended (60,000,000 shares) and (iii) the addition of an exclusive federal forum provision in HoldCo’s bylaws for the resolution of any complaint asserting a cause of action arising under the Securities Act. As such, the rights of our stockholders contained in the amended and restated certificate of incorporation, as amended, and amended and restated bylaws of our company will not substantially change following the Merger Transaction. Further, Liquidia Corporation will be the parent company to both Liquidia Technologies and RareGen following the Merger Transaction, as opposed to Liquidia Technologies operating as a standalone company.

Q: What vote is required by our stockholders to adopt the Merger Agreement and approve the Liquidia Merger?

A: The affirmative vote of the holders of a majority of the outstanding shares of our common stock entitled to vote on the matter is required to adopt the Merger Agreement and approve the Liquidia Merger. See “Voting Procedures” above on page 1 for more information.

Q: What vote is required by our stockholders to approve the grant of discretionary authority to our board of directors to adjourn or postpone the special meeting to a later date, if necessary, to solicit additional proxies if there are insufficient votes in favor of Proposals 1, 2, 3 or 4?

A: Regardless of whether a quorum is present, the affirmative vote of the holders of a majority of the shares of our common stock present or represented by proxy at the special meeting and entitled to vote on the matter is required to approve the grant of discretionary authority to our board of directors to adjourn or postpone the special meeting to a later date, if necessary, to solicit additional proxies if there are insufficient votes in favor of Proposals 1, 2, 3 or 4. See “Voting Procedures” above on page 1 for more information.

Q: Have any of our stockholders agreed to vote in favor of the Merger Transaction?

A: In connection with the Merger Agreement, (i) Mr. Fowler, our and HoldCo’s Chief Executive Officer and a director of our company and HoldCo, (ii) Canaan VIII L.P., a 5% stockholder of our company, (iii) Eshelman Ventures, LLC and Fredric N. Eshelman, together a principal stockholder of our company, and (iv) New Enterprise Associates 12, Limited Partnership and NEA Ventures 2006 Limited Partnership, together a 5% stockholder of our company, which we refer to collectively as the Supporting Stockholders and which beneficially own an aggregate of approximately 34.5% of our common stock outstanding as of the date of this proxy statement/prospectus, each entered into a separate Support Agreement with us, HoldCo and RareGen pursuant to which, among other things, each Supporting Stockholder agreed to support the Merger Transaction by voting the portion of the shares of our common stock over which such Supporting Stockholder has the power to vote (to the extent permitted by applicable law, rule or regulation) in favor of the Merger Agreement and the transactions contemplated thereby. The Support Agreements will terminate upon the earlier of (i) the consummation of the Merger Transaction and (ii) the date on which the Merger Agreement is validly terminated in accordance with its terms. For more information, see “The Merger Agreement — Agreements Entered Into in Connection with the Merger Agreement: Support Agreements” beginning on page 138.

We currently expect that our directors and executive officers will vote their shares in favor of each of the proposals, although none of them has entered into any agreement obligating them to do so, except for Mr. Fowler as indicated above.

Q: What percentage of the outstanding common stock is held by our executive officers and directors as a group?

A: Our executive officers and directors as a group beneficially own approximately 3.2% of the outstanding shares of our common stock of as of July 15, 2020, reflective of (i) shares of common stock that are subject to options and warrants that are currently exercisable within 60 days of that date and (ii) shares of common stock underlying restricted stock units which will have settled into common stock within 60 days of that date.

Q: What vote was required by RareGen members to adopt the Merger Agreement and approve the RareGen Merger?

A: The affirmative vote of a majority of the outstanding common units held was required to adopt the Merger Agreement and approve the RareGen Merger, or the Requisite RareGen Approval. Prior to the

TABLE OF CONTENTS

execution of the Merger Agreement, RareGen obtained the Requisite RareGen Approval. As a result, no further RareGen member approval or action is necessary to complete the Merger Transaction.

Q: Do the directors, officers or affiliates of Liquidia or RareGen have any interests in the Merger Transaction that are different than, or in addition to, the interests of Liquidia and RareGen equityholders generally?

A: Roger A. Jeffs, Ph.D. and Paul B. Manning, current directors of RareGen, will become directors of HoldCo after the Merger Transaction and will be entitled to receive compensation as directors of HoldCo. Mr. Manning is the manager and sole beneficial owner of PBM Capital Finance, which currently owns 70.65% of RareGen’s common units. Dr. Jeffs is the manager of Serendipity BioPharma LLC, which currently owns 25.00% of RareGen’s common units. Dr. Jeffs and Mr. Manning currently own 18,595 and 1,018,466 shares, respectively, of our common stock through various entities which they control. Effective upon the Merger Transaction, the HoldCo board of directors approved an increase in the authorized number of directors of HoldCo from eight to nine. One current director of HoldCo will resign as a director of HoldCo after the Merger Transaction.

See the section entitled “Directors and Officers of HoldCo Following Completion of the Merger Transaction: Director Compensation” beginning on page 150 for a description of the compensation to be received by HoldCo’s directors, which compensation will be the same as what is currently payable to our directors. Additionally, see the section entitled “Proposal 1 — The Merger Transaction: Interests of Certain Directors, Officers and Affiliates of Liquidia and RareGen” beginning on page 116 for a discussion of amounts payable to our transaction committee in connection with the Merger Transaction.

The current officers of Liquidia Technologies will retain their same positions and salaries at HoldCo as those currently held at Liquidia Technologies. One current officer of RareGen, namely Scott Moomaw, RareGen’s Chief Operating Officer, will become an executive officer of HoldCo after the Merger Transaction. Mr. Moomaw is expected to become Senior Vice President, Commercial of HoldCo effective immediately following the Merger Transaction and will receive, among other benefits, an annual salary and a discretionary annual cash bonus commensurate with our other senior executive officers on Mr. Moomaw’s level, and an incentive stock option grant to purchase shares of HoldCo common stock on his first day of employment, vesting over a four-year period with an exercise price equal to the then-fair market value of HoldCo common stock. Damian deGoa, RareGen’s Chief Executive Officer, will resign effective as of the closing of the Merger Transaction.

Pursuant to Mr. deGoa’s and Mr. Moomaw’s current employment agreements with RareGen, upon the closing of the Merger Transaction, (i) Mr. deGoa is eligible to receive a one-time bonus equal to four percent of the total amount of cash and the fair market value of other property actually paid to the members of RareGen in their capacity as such in connection with the Merger Transaction, and (ii) Mr. Moomaw is eligible to receive a one-time bonus equal to two percent of the total amount of cash and the fair market value of other property actually paid to the members of RareGen in their capacity as such in connection with the Merger Transaction. The amounts to be paid to Messrs. deGoa and Moomaw due to the consummation of the Merger Transaction are included in the transaction expenses to be paid by RareGen’s members and cannot be calculated until closing. For more information on the transaction bonuses payable to Messrs. deGoa and Moomaw, see the section entitled “Directors and Executive Officers of RareGen: Executive Compensation: Narrative Disclosure to Summary Compensation Table: deGoa and Moomaw Employment Agreements” beginning on page 163.

Q: Under what circumstances, and when, will RareGen members receive additional HoldCo shares or other consideration following the closing of the Merger Transaction?

A: Pursuant to the terms of the Merger Agreement, RareGen members will receive 6,166,666 shares of HoldCo common stock upon the closing of the Merger Transaction, including 616,666 shares of HoldCo common stock which will be withheld at closing, for the purpose of securing the indemnification obligations of RareGen members to Liquidia indemnitees. On March 31, 2022, any remaining Holdback Shares shall be disbursed to Computershare Trust Company, N.A., which we refer to herein and in the Merger Agreement as the Exchange Agent, for distribution to RareGen members on a pro rata basis. Additionally, RareGen members shall be entitled to a pro rata portion of any RareGen cash at closing in excess of $1 million, which

TABLE OF CONTENTS

is referred to in the Merger Agreement as the “Minimum Cash Amount”. For more information, see “Proposal 1 — The Merger Transaction: The Merger Consideration and Conversion of Securities: Holdback Shares” on page 111 and “The Merger Agreement — Indemnification” beginning on page 130.

Additionally, pursuant to the terms of the Merger Agreement, in 2022 RareGen members will be entitled to receive, on a pro rata basis in the aggregate, up to an aggregate of 2,708,333 shares of HoldCo common stock, based on the amount of 2021 net sales of Sandoz’s generic treprostinil product (as calculated pursuant to the Promotion Agreement). Specifically, the actual amount of shares of HoldCo common stock which RareGen members are entitled to receive on a pro rata basis is subject to a bi-directional sliding scale of 70% — 130% of $47.0 million of net sales of Sandoz’s generic treprostinil product. Such additional shares are referred to as “Net Sales Earnout Shares” in the Merger Agreement. For example, if 2021 net sales falls within $32.9 million (70% of $47.0 million) — $61.1+ million (130% of $47.0 million), then HoldCo shall issue to RareGen members, on a pro rata basis, between 1,458,333 shares — 2,708,333 shares of Net Sales Earnout Shares. For the avoidance of doubt, if 2021 net sales are less than $32.9 million, then no Net Sales Earnout Shares shall be issued to RareGen members, and if 2021 net sales are greater than $61.1 million, then the maximum 2,708,333 Net Sales Earnout Shares will be issued to RareGen’s members on a pro rata basis.

Q: Under what circumstances will RareGen members be required to indemnify Liquidia or its affiliates, and will the damages be paid in shares of HoldCo common stock or cash?

A: The representations and warranties made by RareGen will survive the effective date of the Merger Transaction and remain in full force and effect until on March 31, 2022. Notwithstanding the foregoing, the representations and warranties in Section 3.1.1 (Organization and Qualification; Subsidiaries), Section 3.3 (Capitalization) and Section 3.4 (Authority), which are referred to in the Merger Agreement as “Fundamental Representations”, shall survive indefinitely and the representations and warranties in Section 3.17 (Taxes) shall survive until the date that is 60 days after expiration of the applicable statute of limitations period. The RareGen members, severally and not jointly, in proportion to their respective pro rata ownership of RareGen, shall indemnify and defend each of us, HoldCo and our officers, directors, employees, accountants (other than our public accountants), consultants, legal counsel, advisors, agents and other representatives, which group is collectively referred to as the Liquidia Indemnitees, against, and shall hold each of them harmless from and against, and shall pay and reimburse each of them for, any and all losses incurred or sustained by, or imposed upon, the Liquidia Indemnitees arising out of or resulting from:

•

any inaccuracy in or breach of any of the representations or warranties of RareGen contained in the Merger Agreement or in any certificate or instrument delivered by or on behalf of RareGen pursuant to the Merger Agreement, as of the date such representation or warranty was made or as if such representation or warranty was made on and as of the closing date (except for representations and warranties that expressly relate to a specified date, the inaccuracy in or breach of which will be determined with reference to such specified date);

•

any breach or non-fulfillment of any covenant, agreement or obligation to be performed by RareGen pursuant to the Merger Agreement;

•

any “Indemnified Taxes,” as defined in the Merger Agreement; or

•

any “Transaction Expenses,” as defined in the Merger Agreement.

TABLE OF CONTENTS

the Merger Agreement. The aggregate amount of all losses for which the RareGen members shall be liable (other than fraud claims pursuant to the Merger Agreement) shall not exceed the lesser of (i) such RareGen member’s percentage share of such losses and (ii) the portion of the merger consideration actually received by the RareGen member.

A reduction of the number of Holdback Shares shall be the sole recourse and the exclusive remedy for the Liquidia Indemnitees against the RareGen members for satisfaction of the indemnification obligations of the RareGen members pursuant the Merger Agreement, except in the case of any losses arising out of any inaccuracy in or breach of any Fundamental Representation, indemnified taxes, transaction expenses or arising from fraud. The Liquidia Indemnitees shall seek recovery for any losses arising out of any inaccuracy in or breach of any Fundamental Representation, indemnified taxes, transaction expenses or arising from fraud, (a) first, as a reduction of the number of Holdback Shares (to the extent there remains any Holdback Shares available for such reduction), (b) second, at the election of the indemnifying party, from (i) the return of shares of HoldCo common stock issued to the indemnifying party pursuant to the Merger Agreement, or (ii) as an offset to any Net Sales Earnout Shares issuable to the indemnifying party, and (c) third, directly from the RareGen members by wire transfer of immediately available funds. Notwithstanding the foregoing, the Members’ Representative may elect, in its sole discretion, for any losses to be satisfied via wire transfer of immediately available funds in lieu of any reduction to the number of Holdback Shares, return of shares of HoldCo common stock or offset against the Net Sales Earnout Shares. Any losses payable to a Liquidia Indemnitee pursuant to the indemnification provisions contained in the Merger Agreement shall be satisfied from the RareGen members, severally and not jointly, in proportion to their respective pro rata ownership of RareGen. Additionally, all indemnification payments made under the Merger Agreement shall be treated by the parties as an adjustment to the merger consideration for tax purposes, unless otherwise required by law.

Q: Under what circumstances will Liquidia Technologies or HoldCo be required to indemnify the RareGen members or their affiliates, and will the damages be paid in shares of HoldCo common stock or cash?

A: The representations and warranties of our company, HoldCo Liquidia Merger Sub and RareGen Merger Sub shall survive the closing and shall remain in full force and effect until March 31, 2022; provided, that the representations and warranties in Section 4.1 (Organization and Qualification; Subsidiaries), Section 4.3 (Authority) and 4.15 (Exclusivity of Representations), which are referred to in the Merger Agreement as the “HoldCo Fundamental Representations,” shall survive indefinitely. HoldCo shall indemnify and defend each RareGen member and their respective directors, officers, employees, accountants, consultants, legal counsel, advisors, agents and other representatives, which group is collectively referred to as the RareGen Member Indemnitees, against, and shall hold each of them harmless from and against, and shall pay and reimburse each of them for, any and all losses incurred or sustained by, or imposed upon, the RareGen Member Indemnitees arising out of or resulting from:

any inaccuracy in or breach of any of the representations or warranties of our company, HoldCo, Liquidia Merger Sub or RareGen Merger Sub contained in the Merger Agreement or in any certificate or instrument delivered by or on behalf of our company, HoldCo, Liquidia Merger Sub or RareGen Merger Sub pursuant to the Merger Agreement, as of the date such representation or warranty was made or as if such representation or warranty was made on and as of the closing date (except for representations and warranties that expressly relate to a specified date, the inaccuracy in or breach of which will be determined with reference to such specified date); or

•

any breach or non-fulfillment of any covenant, agreement or obligation to be performed by us, HoldCo, Liquidia Merger Sub or RareGen Merger Sub pursuant to the Merger Agreement.

TABLE OF CONTENTS

exceed the Cap. The aggregate amount of all losses arising out of or resulting from any inaccuracy in or breach of any HoldCo Fundamental Representation for which HoldCo shall be liable, when added to any other losses for which RareGen members may be liable thereunder, shall not exceed the value of the merger consideration actually paid to the RareGen members.

We and RareGen expect to complete the Merger Transaction late in the third calendar quarter of 2020 or early in the fourth calendar quarter of 2020. However, we and RareGen cannot predict the exact timing of the completion of the Merger Transaction because the transaction is subject to several conditions.

Q: Are there any regulatory consents or approvals that are required to complete the Merger Transaction?

A: Neither we nor RareGen are aware of the need to obtain any regulatory approvals in order to complete the Merger Transaction other than the declaration by the SEC of the effectiveness of the registration statement of which this proxy statement/prospectus is a part.

We and RareGen intend to obtain the SEC’s approval and any additional regulatory approvals that may be required. However, none of the parties can assure you that all of the approvals will be obtained.

•

the continued truth and correctness at the closing of the Merger Transaction of the representations and warranties given by RareGen as of the date of the execution of the Merger Agreement; or, if this condition is not so satisfied, any failures of such representations and warranties to be so true and correct do not have, in the aggregate, a material adverse effect on the assets, liabilities, business, financial condition, results of operations or capitalization of RareGen;

TABLE OF CONTENTS

•

by either us or RareGen if a governmental entity has taken any final and non-appealable action permanently restraining, enjoining or otherwise prohibiting the transactions contemplated by the Merger Agreement and the related agreements;

•

by either us or RareGen if our stockholders have not adopted the Merger Agreement and approved the Merger Transaction;

•

by us, if our board of directors determines to accept a superior proposal (as defined in the section entitled “The Merger Agreement — Termination of the Merger Agreement” beginning on page 134), but only after we (i) provide RareGen with not less than five business days’ notice of our determination to accept such superior proposal, including all material terms thereof and (ii) fulfills our obligations in the Merger Agreement upon such termination; and

•

by either us or RareGen if any representation, warranty, covenant or agreement of the other party set forth in the Merger Agreement is or becomes untrue in a manner that would result in a failure of a closing condition and is not curable within 30 days after written notice.

Q: Could payment of termination fees be required? (see page 134)

A: Yes. If the Merger Agreement is terminated (i) by us if our board of directors decides to accept a superior proposal or (ii) by RareGen if our board of directors changes its recommendation to stockholders following the receipt of an alternative proposal, then we shall pay to RareGen a termination fee of $7.5 million, as more fully discussed in the section entitled “The Merger Agreement — Termination Fee” beginning on page 134.

Q: May we or RareGen negotiate with other parties? (see page 126)

A: The Merger Agreement contains provisions prohibiting us or RareGen from seeking an alternative transaction to the Merger Transaction. These “no solicitation” provisions apply to us and RareGen and their respective officers, directors, affiliates or employees as well as any investment banker, attorney or other advisor or representative retained by any of them. Under these provisions, covered persons may not, directly or indirectly:

•

solicit, initiate or knowingly encourage or facilitate any alternative proposal (as defined under “Merger Agreement: Meeting of Stockholders” on page 122) or RareGen acquisition proposal (as defined in the section entitled “The Merger Agreement — No Solicitation” beginning on page 126);

•

enter into any agreement with respect to any alternative proposal or RareGen acquisition proposal, as applicable, or enter into any agreement with respect to any alternative proposal or RareGen acquisition proposal or enter into any agreement or understanding requiring the abandonment, termination or failure to complete the Merger Transaction or any other transaction contemplated by the Merger Agreement or any ancillary agreement; or

•

participate in discussions or negotiations regarding, or furnish to any person any information with respect to, or take any other action to facilitate any inquiries or the making of any proposal that constitutes or may reasonably be expected to lead to, any alternative proposal or RareGen acquisition proposal, as applicable.

Notwithstanding the restrictions described above, if at any time prior to obtaining stockholder approval of the Merger Transaction at our special meeting, we and/or our representatives receive a bona fide, unsolicited written acquisition proposal that did not result from a breach of the Merger Agreement, we and/or our representatives may engage in negotiations and discussions with, and furnish any information and other access (so long as all such information and access has previously been made available to RareGen or is made available to RareGen before or concurrently with the time such information or access is made available to such person) to, any person making such alternative proposal if, and only if, our board of directors determines in good faith, after consultation with our outside legal and financial advisors, that (i) such alternative proposal constitutes or is reasonably likely to become a superior proposal and (ii) the failure of our board of directors to furnish such information or access or enter into such discussions or negotiations would violate its fiduciary duties under applicable law; but before furnishing any such information, we shall

TABLE OF CONTENTS

have received from the person making such alternative proposal an executed confidentiality agreement with terms at least as restrictive in all material respects on such person as the confidentiality agreement between us and RareGen, which confidentiality agreement shall not prohibit us from complying with the terms of this “no solicitation” covenant.

For more information, please see the section entitled “The Merger Agreement — No Solicitation” beginning on page 126.

Q: Will our stockholders recognize a taxable gain or loss for U.S. federal income tax purposes as a result of the Merger Transaction?

A: Based upon customary covenants, assumptions and representations as to factual matters described in the section entitled “Proposal 1 — The Merger Transaction: Material U.S. Federal Income Tax Consequences” beginning on page 114, all of which must continue to be true and accurate as of the effective time of the Merger Transaction, the Merger Transaction is intended to qualify as an exchange described in Section 351 of the Internal Revenue Code of 1986, as amended, or the Code. Provided the Merger Transaction is treated as intended, stockholders should generally not recognize taxable gain or loss for U.S. federal income tax purposes as a result of the Merger Transaction.

Tax matters are very complicated, and the tax consequences of the Merger Transaction to our stockholders will depend on the facts of each stockholder’s own situation. For a description of the material U.S. federal income tax consequences of the Merger Transaction to our stockholders, please see the information set forth in the section entitled “Proposal 1 — The Merger Transaction: Material U.S. Federal Income Tax Consequences” beginning on page 114. Each stockholder is also encouraged to consult the stockholder’s own tax advisor for a full understanding of the tax consequences of the Merger Transaction.

Q: What is the anticipated accounting treatment for the Merger Transaction?

A: In accordance with U.S. generally accepted accounting principles, HoldCo will account for the acquisition of RareGen through the Merger Transaction under the acquisition method of accounting for business combinations, and we will be treated as the accounting acquirer. For more information, please see the section entitled “Proposal 1 — The Merger Transaction: Accounting Treatment” beginning on page 116.

Q: What if I object to the Merger Transaction? Do I have appraisal rights?

A: Under applicable Delaware law, our stockholders and RareGen members will not have appraisal rights in connection with the issuance of HoldCo common stock in the Merger Transaction.

Q: Will HoldCo have a different CUSIP or ticker symbol than Liquidia Technologies following completion of the Merger Transaction?

A: No, following completion of the Merger Transaction, HoldCo will have the same CUSIP and ticker symbol, “LQDA”, as Liquidia Technologies.

Q: Will HoldCo bear the costs and expenses and be responsible for all final, non-appealable damages of RareGen’s and Sandoz’s litigation with United Therapeutics Corporation or realize any recovery from such litigation?

A: No. On June 4, 2020 RareGen entered into a financing agreement with Henderson SPV, LLC, or Henderson, to cover the prospective costs of the litigation, or the UTC/Smiths Medical litigation, with United Therapeutics Corporation, or United Therapeutics, and Smiths Medical ASD, Inc., or Smiths Medical, from the date of this agreement. Additionally, pursuant to a litigation funding and indemnification agreement between RareGen and the Members’ Representative to be effective at the closing of the Merger Transaction, which we refer to as the litigation funding and indemnification agreement, in the event Henderson is no longer required to, or fails to timely, make payments to RareGen pursuant to the financing agreement, the Members’ Representative will make payments to or on behalf of RareGen to be used by RareGen exclusively for the payment of counsel fees and litigation expenses incurred in connection with the UTC/Smiths Medical litigation. As consideration for funding the UTC/Smiths Medical litigation, Henderson and the Members’ Representative are each entitled to a portion of the litigation proceeds prior to such proceeds, upon a settlement or recovery of final, non-appealable damages, ultimately being distributed to RareGen

TABLE OF CONTENTS

members on a pro rata basis. HoldCo or its subsidiaries post-closing will not be entitled to any proceeds resulting from, or bear any financial or other liability for, the UTC/Smiths Medical litigation. For more information on the financing agreement and the litigation funding and indemnification agreement, see “RareGen’s Business: Legal Proceedings and Related Agreements” beginning on page 76 and “The Merger Agreement — Agreements Entered Into in Connection with the Merger Agreement: Litigation Funding and Indemnification Agreement” beginning on page 139, respectively.

Q: Are there other proposals that I should consider?

A: Yes. In connection with the Merger Transaction, we are also asking its stockholders to consider and vote to approve the HoldCo 2020 Incentive Plan, approve the HoldCo 2020 ESPP, ratify ratify the appointment of HoldCo’s independent auditor for 2020 and grant discretionary authority to our board of directors to adjourn or postpone the special meeting to a later date if there are insufficient votes in favor of Proposals 1, 2, 3 or 4.

Q: What do I need to do now?

A: You are encouraged to carefully read and consider the information contained in this proxy statement/prospectus, including the annexes, and to consider how the Merger Transaction and other proposals will affect you. You should also review the documents referenced under the section entitled “Where You Can Find Additional Information” beginning on page 202. If you are a Liquidia Technologies stockholder, you should then submit a proxy as soon as possible in accordance with the instructions provided in this proxy statement/prospectus and on the enclosed proxy card or submit your voting instructions over the internet or by telephone if those options are available to you.

Q: How do I vote?

A: If you are a holder of record of our common stock on the Record Date, you are eligible to vote virtually at the special meeting or by submitting a proxy for the special meeting. See above under “Voting Instructions” for more information on voting at the special meeting.

Q: Do our stockholders need to take any action with respect to their Liquidia Technologies common stock holdings?

A: No. Each share of our common stock issued and outstanding immediately prior to the effective time of the Merger Transaction, whether certificated or held in book-entry form, shall be converted into an equal number of shares of HoldCo common stock without any action on the part of the holder. All such shares of our common stock shall no longer be outstanding and shall automatically be canceled and shall cease to exist.

Q: What should I do if I receive more than one set of voting materials?

A: You may receive more than one set of voting materials, including multiple copies of this proxy statement/prospectus and multiple proxy cards or voting instruction cards. For example, if you hold our shares in more than one brokerage account, you will receive a separate voting instruction card for each brokerage account in which you hold shares. If you are a holder of record and your shares are registered in more than one name, you will receive more than one proxy card. Our stockholders should complete, sign, date and return each proxy card and voting instruction card they receive. See above under “Voting Instructions” for more information on voting at the special meeting.

[MISSING IMAGE: tm2025040d1-fc_postmerger4c.jpg]

TABLE OF CONTENTS

Treatment of Liquidia Technologies common stock, Stock Options, Warrants and Restricted Stock Units

Upon the closing of the Merger Transaction, (i) each share of our common stock, whether certificated or held in book-entry form, will automatically convert into one share of HoldCo common stock, (ii) each option or warrant to purchase our common stock will convert into an option or warrant to purchase an identical number of shares of HoldCo common stock as are underlying such Liquidia Technologies option or warrant, and the exercise price per share and other terms will be identical to the Liquidia Technologies option or warrant, and (iii) each restricted stock unit to acquire our common stock will automatically convert into the right to receive one share of HoldCo common stock for each share of our common stock subject to such restricted stock unit grant.

Treatment of RareGen Common Units and Consideration to be Received in the Merger

Pursuant to the terms of the Merger Agreement, RareGen members are to receive, on a pro rata basis in the aggregate, 6,166,666 shares of HoldCo common stock, of which 5,550,000 shares shall be issued to RareGen members upon the closing of the Merger Transaction and 616,666 shares of which will be withheld at closing, which we refer to herein and in the Merger Agreement as the Holdback Shares, for the purpose of securing the indemnification obligations of RareGen members to Liquidia Indemnitees. On March 31, 2022, any remaining Holdback Shares shall be disbursed to Computershare Trust Company, N.A., which we refer to herein and in the Merger Agreement as the Exchange Agent, for distribution to RareGen members on a pro rata basis. Additionally, at closing, RareGen members shall be entitled to a pro rata portion of any RareGen cash at closing in excess of $1 million, which is referred to in the Merger Agreement as the “Minimum Cash Amount”. For more information, see “Proposal 1 — The Merger Transaction: The Merger Consideration and Conversion of Securities: Holdback Shares” on page 111 and “The Merger Agreement — Indemnification” beginning on page 130.

Additionally, pursuant to the terms of the Merger Agreement, RareGen members are entitled to receive, on a pro rata basis in the aggregate, up to an aggregate of 2,708,333 shares of HoldCo common stock in 2022, based on the amount of 2021 net sales of Sandoz’s generic treprostinil product (as calculated pursuant to the Promotion Agreement). Specifically, the actual amount of shares of HoldCo common stock which RareGen members are entitled to receive in 2022 on a pro rata basis is subject to a bi-directional sliding scale of 70% — 130% of $47.0 million of net sales of Sandoz’s generic treprostinil product. Such additional shares are referred to as “Net Sales Earnout Shares” in the Merger Agreement. For example, if 2021 net sales falls within $32.9 million (70% of $47.0 million) — $61.1+ million (130% of $47.0 million), then HoldCo shall issue to RareGen members, on a pro rata basis, between 1,458,333 shares — 2,708,333 shares of Net Sales Earnout Shares. For the avoidance of doubt, if 2021 net sales is less than $32.9 million, then no Net Sales Earnout Shares shall be issued to RareGen members, and if 2021 net sales is greater than $61.1 million, then the maximum 2,708,333 Net Sales Earnout Shares will be issued to RareGen’s members on a pro rata basis.

Material U.S. Federal Income Tax Considerations

The parties intend that the Merger Transaction will qualify as an exchange described in Section 351 of the Code. A holder of our common stock who exchanges all of his, her or its shares of our common stock and receives only shares of HoldCo common stock in the Merger Transaction is not intended to recognize gain or loss for U.S. federal income tax purposes. This gain or loss will generally constitute capital gain or loss. The deductibility of capital losses is subject to limitations. Each holder’s aggregate tax basis in the HoldCo capital stock received in the Merger Transaction will be the same as his, her or its aggregate tax basis in our common stock exchanged in the Merger Transaction. The holding period of the HoldCo common stock received in the Merger Transaction by a holder of our common stock will include the holding period of our common stock that he, she or it exchanged in the Merger Transaction.

Tax matters are very complicated, and the tax consequences of the Merger Transaction to a Liquidia Technologies stockholder will depend on the facts of each stockholder’s own situation. For a description of the material U.S. federal income tax consequences of the Merger Transaction to our stockholders, please see the information set forth in the section entitled “Proposal 1 — The Merger Transaction: Material U.S.

TABLE OF CONTENTS

Federal Income Tax Consequences” beginning on page 114. Each Liquidia Technologies stockholder is also encouraged to consult the stockholder’s own tax advisor for a full understanding of the tax consequences of the Merger Transaction.

Recommendation of the Liquidia Technologies Board of Directors

After careful consideration, our board of directors recommends that our stockholders vote “FOR” each proposal being submitted to a vote of our stockholders at the special meeting. All of the members of our board of directors approved such recommendations.

For a more complete description of our reasons for the Merger Transaction and the recommendations of our board of directors, see the sections entitled “Proposal 1 — The Merger Transaction: Liquidia’s Reasons for the Merger Transaction” beginning on page 95 and “Voting Procedures” beginning on page 1.

Opinion of Jefferies LLC

We retained Jefferies LLC, or Jefferies, an investment banking firm, as our financial advisor in connection with the Merger Transaction. In connection with the engagement, we requested that Jefferies evaluate the fairness to our stockholders, from a financial point of view, of the number of shares of HoldCo common stock to be received by our stockholders in the Liquidia Merger pursuant to the Merger Agreement. At a special meeting of our board of directors on June 28, 2020, Jefferies’ representatives rendered an oral opinion, confirmed by delivery of a written opinion dated June 29, 2020, to our board of directors to the effect that, as of that date and based on and subject to the various assumptions made, procedures followed, matters considered and limitations and qualifications on the scope of review undertaken as described in its opinion, the number of shares of HoldCo common stock to be received by our stockholders in the Liquidia Merger pursuant to the Merger Agreement was fair, from a financial point of view, to the holders of our common stock. The full text of the written opinion of Jefferies, dated June 29, 2020, which sets forth the various assumptions made, procedures followed, matters considered and limitations and qualifications on the scope of the review undertaken by Jefferies in providing its opinion, is set forth as Annex B and a detailed description of the Jefferies opinion can be found at “Proposal 1 — The Merger Transaction: Opinion of Jefferies LLC” beginning on page 98. Jefferies provided its fairness opinion for the use and benefit of our board of directors (in its capacity as such) in its consideration of the Merger Transaction, and Jefferies’ opinion does not address the relative merits of the Merger Transaction contemplated by the Merger Agreement as compared to any alternative transaction or opportunity that might be available to us, nor does it address our underlying business decision to engage in the Merger Transaction or the terms of the Merger Agreement or the documents referred to therein. The fairness opinion does not constitute a recommendation as to how any stockholder of our company should vote or act with respect to the Merger Transaction or any other matter. We urge our stockholders to read the opinion of Jefferies carefully and in its entirety.

The Cooperation Agreement entered into with PBM Capital Finance and PD Joint Holdings and is referred to herein as the PBM/PD Cooperation Agreement and the Cooperation Agreement entered into with Serendipity is referred to herein as the Serendipity Cooperation Agreement, and they are together referred to as the Cooperation Agreements.

Pursuant to the Cooperation Agreements, prior to the effectiveness of the Merger Transaction, but conditioned on the closing of the Merger Transaction, HoldCo’s board of directors agreed to take all necessary actions to increase the authorized number of directors from eight to nine and appoint Roger A. Jeffs, Ph.D. and Paul B. Manning as a Class I and Class III director of HoldCo, respectively, for terms expiring at HoldCo’s 2022 and 2021 annual meetings of stockholders, respectively, and until their successors are elected and qualified, or until such director’s earlier resignation, removal or death. Prior to the closing date of the Merger Transaction, Ralph Snyderman, a current Class I director of our company and HoldCo, will resign, conditional and effective upon the closing date, and Dr. Jeffs and Mr. Manning will fill the vacancies created by this resignation and the increase in authorized number of directors, respectively. The size of the board of directors of HoldCo shall not exceed nine directors during the Cooperation Period (as defined below) unless at least two-thirds of the members of the board of directors approve an increase in the size of the board. Subject to any applicable corporate governance documents of HoldCo, and applicable stock exchange rules, concurrently upon appointment to the board of directors, (A) Dr. Jeffs shall be appointed to the Compensation Committee and (B) Mr. Manning shall be appointed to the Nominating and Corporate Governance Committee and, in each case, HoldCo agrees to maintain such committee appointments during the term of the applicable Cooperation Agreement, as long as each such director (or, as applicable, their Replacement Designee (as defined below)) continues to serve on the HoldCo board of directors.

Pursuant to the Cooperation Agreements, during the Cooperation Period, as long as the New Company Investor owns at least 66% of the shares of HoldCo common stock held on the date of closing of the Merger Transaction (and subject to adjustment for stock splits, reclassifications, combinations, buybacks or similar transactions), which amount is referred to as the “Ownership Minimum,” and in the event that any new director appointed pursuant to the applicable Cooperation Agreement, referred to therein as a “New Director” (or any Replacement Designee, as applicable) becomes unwilling or unable to serve as a director and ceases to be a director, resigns as a director or is removed as a director, or for any other reason fails to serve or is not serving as a director at any time prior to the end of the Cooperation Period, then such New Company Investor shall be entitled to designate, subject to the approval (not to be unreasonably withheld) of the applicable committee of the HoldCo board of directors, a candidate for replacement of such New Director, which replacement is referred to in the Cooperation Agreements as a “Replacement Designee”. Any Replacement Designee shall qualify as an independent director of HoldCo under applicable rules of the SEC, the rules of any stock exchange on which HoldCo is traded and applicable governance policies of HoldCo. Following the approval of a candidate for Replacement Designee by the applicable committee of the HoldCo board of directors, the HoldCo board of directors shall promptly appoint such Replacement Designee to the HoldCo board of directors. Upon his or her appointment to the HoldCo board of directors, such Replacement Designee shall be deemed a “New Director” for all purposes under each Cooperation Agreement.

RareGen members will not enter into a lock-up agreement for any shares of HoldCo common stock acquired after the closing date of the Merger Transaction, such as upon the acquisition of Holdback Shares or Net Sales Earnout Shares.

TABLE OF CONTENTS

No Solicitation Restriction

The Merger Agreement contains provisions prohibiting us or RareGen from seeking an alternative transaction to the Merger Transaction. These “no solicitation” provisions apply to us and RareGen and our and their respective officers, directors, affiliates or employees as well as any investment banker, attorney or other advisor or representative retained by any of them. Under these provisions, covered persons may not, directly or indirectly:

•

solicit, initiate or knowingly encourage or facilitate any alternative proposal (as defined under “The Merger Agreement: Meeting of Stockholders” on page 122) or RareGen acquisition proposal (as defined in the section entitled “The Merger Agreement — No Solicitation” beginning on page 126);

•

For more information, please see the section entitled “The Merger Agreement — No Solicitation” beginning on page 126.

Accounting Treatment of the Merger Transaction

In accordance with U.S. generally accepted accounting principles, HoldCo will account for the acquisition of RareGen through the Merger Transaction under the acquisition method of accounting for business combinations, and we will be treated as the accounting acquirer. For more information, please see the section entitled “Proposal 1 — The Merger Transaction: Accounting Treatment” beginning on page 116.

Regulatory Clearances Required for the Merger Transaction

We and RareGen have each agreed to use their reasonable best efforts to obtain all necessary waivers, consents, approvals, orders and authorizations from governmental entities with respect to the Merger Agreement required under applicable law. Certain conditions to closing the Merger Transaction include, but are not limited to: (i) the HSR Act waiting period (together with any extensions thereof) relating thereto

TABLE OF CONTENTS

shall have expired or been terminated, if applicable; (ii) the absence of any order by any governmental entity or court, or consent, approval or other authorization, that prevents or prohibits the Merger Transaction or any other transactions contemplated by the Merger Agreement, and the absence of any pending legal proceeding seeking such order; (iii) the declaration by the SEC of the effectiveness of the registration statement of which this proxy statement/prospectus is a part and the absence of any stop order suspending such effectiveness; and (iv) the shares of HoldCo common stock to be issued to our stockholders and RareGen members pursuant to the Merger Transaction shall be authorized for listing on the Nasdaq Capital Market at the effective time of the Merger Agreement, subject to official notice of issuance. We and RareGen have jointly determined that a notification with the United States Federal Trade Commission, or the FTC, and the Antitrust Division of the United States Department of Justice, or the DOJ, is not required in connection with the Merger Transaction and therefore the parties will not need to observe a mandatory premerger waiting period before completing the Merger Transaction.

We and RareGen believe that the Merger Transaction does not raise substantial regulatory concerns and that all applicable regulatory approvals will be obtained on a timely basis.

Comparison of Stockholder and Unitholder Rights

Liquidia Technologies is incorporated under the laws of the State of Delaware as a corporation and the rights of our stockholders are governed by the laws of the State of Delaware, including the Delaware General Corporation Law, or the DGCL, our amended and restated certificate of incorporation, as amended, and our amended and restated bylaws. RareGen is formed under the laws of the State of Delaware as a limited liability company and the rights of RareGen unitholders are governed by the Delaware Limited Liability Company Act, or the DLLCA, and RareGen’s operating agreement, effective August 6, 2018, as amended, or the operating agreement. As a result of the Merger Transaction, our stockholders and RareGen unitholders will become HoldCo stockholders. HoldCo is incorporated under the laws of the State of Delaware and the rights of HoldCo stockholders will be governed by the laws of the State of Delaware, including the DGCL, HoldCo’s certificate of incorporation and HoldCo’s bylaws. As a result, the rights of our stockholders and RareGen unitholders who become HoldCo stockholders will continue to be governed by the laws of the State of Delaware (although in the case of RareGen, under the DGCL and not the DLLCA) but will also be governed by HoldCo’s certificate of incorporation and HoldCo’s bylaws.

As Liquidia Technologies’ successor following the closing of the Merger Transaction, the certificate of incorporation and bylaws of HoldCo are substantially identical to the amended and restated certificate of incorporation, as amended, and the amended and restated bylaws of our company. The only changes between the governing documents of our company and HoldCo are (i) the company name, (ii) the number of shares of HoldCo common stock authorized under the HoldCo certificate of incorporation (80,000,000 shares) versus the number of shares of our common stock currently authorized under our amended and restated certificate of incorporation, as amended (60,000,000 shares) and (iii) the addition of an exclusive federal forum provision in HoldCo’s bylaws for the resolution of any complaint asserting a cause of action arising under the Securities Act. As such, the rights of our stockholders contained in the amended and restated certificate of incorporation, as amended, and amended and restated bylaws of our company will not substantially change following the Merger Transaction. See “Description of HoldCo Capital Stock Following Completion of the Merger Transaction” on page 167 for more information.

The comparison of stockholder and unitholder rights contained in the section entitled “Comparison of Stockholder and Unitholder Rights” beginning on page 172 is based on the certificate of incorporation and bylaws of HoldCo that are currently in effect and will be in effect following the completion of the Merger Transaction. The following discussion is not intended to provide a comprehensive discussion of each company’s governing documents and is qualified in its entirety by reference to HoldCo’s certificate of incorporation and bylaws attached to the registration statement of which this proxy statement/prospectus is a part as Exhibit 3.1 and Exhibit 3.2, respectively, and are incorporated by reference herein. Copies of our governing documents have been filed with the SEC. We encourage you to read the governing documents and relevant provisions of the DGCL and the DLLCA.

Appraisal Rights

Appraisal rights are statutory rights that, if applicable under law, enable stockholders to dissent from an extraordinary transaction, such as a merger, and to demand that the corporation pay the fair value for their shares as determined by a court in a judicial proceeding instead of receiving the consideration offered to stockholders in connection with the extraordinary transaction. The laws of the State of Delaware, which is the state of incorporation and formation of both our company and RareGen, respectively govern whether or not appraisal rights are available in a given merger.

Stockholders do not have appraisal rights with respect to shares of any class or series of stock if such shares of stock are listed on a national securities exchange. Therefore, because our common stock is listed on Nasdaq, and will receive in the merger only shares of HoldCo common stock, which will be publicly listed on Nasdaq, holders of our common stock will not be entitled to appraisal rights in the merger with respect to their shares of our common stock.

Under the DLLCA, appraisal rights do not exist except when those rights are specifically provided for in the company agreement or an agreement of merger. Because appraisal rights are not specifically provided for in the Merger Agreement or RareGen’s operating agreement, dated as of August 7, 2018, as amended, or the operating agreement, RareGen members also do not have appraisal rights in connection with the Merger Transaction.

For more information on the appraisal rights as it relates to the Merger Transaction, see the section entitled “Proposal 1 — The Merger Transaction: Appraisal Rights” beginning on page 118.

RISK FACTORS

If you are a Liquidia Technologies stockholder, you should carefully consider the following risk factors before deciding whether to vote to adopt the Merger Agreement and approve the Liquidia Merger and the other proposals presented herein. These risk factors should be considered in conjunction with the other information included in this proxy statement/prospectus, including the matters addressed in the section entitled “Forward-Looking Statements” on page 87. Additional risks and uncertainties not presently known to us or RareGen, or that are not currently believed to be important to you, also may adversely affect the Merger Transaction and HoldCo following completion of the Merger Transaction.

Risks Related to the Merger Transaction

We may not achieve the benefits expected from the Merger Transaction, which may harm our business and could result in the loss of key suppliers, licensees, collaborators, business partners and personnel.

Achieving the benefits of the Merger Transaction will depend in part on the successful integration of the technology, platforms, capabilities, operations and personnel of our company and RareGen in a timely and efficient manner to minimize the impact on suppliers, licensees, collaborators, business partners, employees and management. The integration of our company and RareGen will be a complex, time-consuming and expensive process and may harm our business, financial condition and results of operations. The challenges involved in this integration include, but are not limited to, the following:

•

retaining existing suppliers, licensees, collaborators and business partners of both our company and RareGen;

•

retaining and integrating directors, executive management and other key employees of both our company and RareGen;

•

onboarding RareGen employees to our company’s benefit plans and payroll;

•

managing the RareGen field sales team;

•

consolidating the companies’ promotional, sales and commercialization efforts so that the industry receives useful information about HoldCo’s product candidates and services;

•

identifying and eliminating redundant operations and assets;

•

coordinating research and development activities to integrate existing technologies and enhance introduction of new products and technologies;

•

persuading employees that the business cultures of our company and RareGen are compatible; and

•

maintaining and upgrading uniform standards, controls, procedures and policies for compliance with rules and regulations customary in our line of business, including but not limited to federal and state healthcare requirements and internal controls and procedures that we will be required to maintain under the Sarbanes-Oxley Act of 2002.

We cannot assure you that we can successfully integrate our business with that of RareGen in a timely manner or that all or any of the anticipated benefits of the Merger Transaction will be realized.

The Merger Transaction involves the integration of two companies that previously have operated independently. Risks to the successful integration of the two companies include:

•

the impairment of relationships with employees, suppliers, licensees, collaborators and business partners;

•

the potential disruption of our business and distraction of our management;

•

the difficulty of incorporating acquired technology, platforms and relationships from RareGen into our offerings;

•

not achieving expected synergies as a result of a number of factors, including, but not limited to, the failure of the FDA to timely approve our NDA for LIQ861 and/or the failure of Sandoz’s treprostinil pursuant to the Promotion Agreement to be administered subcutaneously; and

TABLE OF CONTENTS

•

unanticipated expenses related to integration of the two companies.

We may not succeed in addressing these risks or any other problems encountered in connection with the Merger Transaction.

No market currently exists for HoldCo common stock, and the market value of HoldCo common stock after the Merger Transaction could be less than the value of RareGen equity and our common stock before the Merger Transaction.

The market value of the shares of HoldCo common stock that you will receive in exchange for common units of RareGen or shares of our common stock in the Merger Transaction, in the case of RareGen, was not known at the time RareGen members voted to adopt the Merger Agreement and approve the RareGen Merger, and in the case of our company, will not be known at the time our stockholders vote to adopt the Merger Agreement and approve the Liquidia Merger because the shares of HoldCo common stock will not trade publicly until the completion of the Merger Transaction. Common units of RareGen and shares of our common stock may have a greater value than the shares of HoldCo common stock for which they will be exchanged in the Merger Transaction.

The pro forma financial statements included in this proxy statement/prospectus are presented for informational purposes only and may not be an indication of our financial condition or results of operations following completion of the Merger Transaction.

The HoldCo unaudited pro forma condensed combined financial statements contained in this proxy statement/prospectus are presented for informational purposes only and are not necessarily indicative of what our actual financial condition or results of operations would have been had the Merger Transaction been completed on the dates indicated. The HoldCo unaudited pro forma condensed combined financial statements reflect adjustments, which are based upon preliminary estimates, to record the RareGen identifiable assets acquired and liabilities assumed at fair value and the resulting goodwill recognized. The purchase price allocation reflected in this document is preliminary, and final allocation of the purchase price will be based upon the actual purchase price and the fair value of the assets and liabilities of RareGen as of the date of the completion of the merger. Accordingly, the final acquisition accounting adjustments may differ materially from the pro forma adjustments reflected in this document. For more information, see the section entitled “Unaudited Pro Forma Condensed Combined Financial Statements of HoldCo,” beginning on page 77.

You will receive a fixed percentage of HoldCo common stock despite changes in the values of RareGen common units or our common stock.

There will be no adjustment to the percentage of HoldCo common stock to be exchanged for each unit of RareGen and each share of our common stock due to changes in the fair market value of either common units of RareGen or our common stock. In addition, neither we nor RareGen may terminate the Merger Agreement or “walk away” from the Merger Transaction solely because of changes in the value of either company’s equity. Therefore, if the value of common units of RareGen or our common stock changes relative to the value of the other, there will be no change in what you receive in the Merger Transaction to reflect this. The share price of our common stock is subject to the general price fluctuations in the market for publicly traded equity securities and has experienced significant volatility. Our stockholders should obtain recent market quotations for our common stock. We and RareGen cannot predict or give any assurances as to the market price of our common stock before the Merger Transaction or of HoldCo common stock at any time after the completion of the Merger Transaction.

The market price for HoldCo common stock following the closing may be affected by factors different from those that historically have affected our common stock and RareGen common units.

Upon completion of the Merger Transaction, holders of shares of our common stock and RareGen common units will become holders of HoldCo common stock. Our business differs from that of RareGen, and accordingly the results of operations of HoldCo will be affected by some factors that are different from those currently affecting our results of operations. The results of operation of HoldCo may also be affected by factors different from those currently affecting us. For a discussion of our and RareGen’s businesses and of important factors to consider in connection with those businesses, see the documents

incorporated by reference in this proxy statement/prospectus and referred to in the section entitled “Where You Can Find Additional Information” beginning on page 202 and the section entitled “RareGen’s Business” beginning on page 69, respectively.

Any delay in completing the Merger Transaction may reduce or eliminate the benefits expected to be achieved thereunder.

The Merger Transaction is subject to a number of conditions beyond our and RareGen’s control that may prevent, delay or otherwise materially adversely affect its completion. Neither we nor RareGen can predict whether and when these conditions will be satisfied. Any delay in completing the Merger Transaction could cause us not to realize some or all of the operational and revenue synergies and other benefits that we and RareGen expect to achieve if the merger is successfully completed within its expected time frame.

Completion of the Merger Transaction is subject to a number of conditions, which, if not satisfied or waived, may result in termination of the Merger Agreement.

The Merger Agreement contains a number of conditions to completion of the Merger Transaction. The conditions to the obligations of our company and RareGen that must be satisfied or waived before the completion of the Merger Transaction include, among other things, the following, subject to certain exceptions and qualifications:

•

declaration by the SEC of the effectiveness of the registration statement of which this proxy statement/prospectus is a part and the absence of any stop order suspending such effectiveness;

•

our stockholder approval of the Merger Agreement and the Liquidia Merger;

•

the receipt of all required consents, approvals and authorizations of any governmental, administrative, judicial or regulatory authority;

•

the Hart-Scott-Rodino Act, or the HSR Act, waiting period (together with any extensions thereof) relating thereto shall have expired or been terminated, if applicable;

•

RareGen and the Members’ Representative shall have entered into the litigation funding and indemnification agreement; and

•

the HoldCo common stock issuable to our stockholders and RareGen members in the Merger Transaction being approved for listing on the Nasdaq Capital Market, subject to official notice of issuance.

The conditions to the obligations of our company to effect the Liquidia Merger also include, among other things, the following, subject to certain exceptions and qualifications:

•

RareGen’s performance or compliance in all material respects with all agreements and covenants required by the Merger Agreement on or prior to the effective time of the Merger Transaction;

TABLE OF CONTENTS

•

the resignation of all RareGen officers, directors, and Joint Steering Committee members (other than Scott Moomaw) and the termination of Damian deGoa’s employment agreement with RareGen;

•

Sandoz’s consent and waiver to the transactions contemplated by the Merger Agreement, which waiver of its Promotion Agreement termination right upon a change of control of RareGen was obtained subject to the Merger Transaction closing on or prior to September 30, 2020 pursuant to the first amendment to the Promotion Agreement, shall be in effect and shall not have been rescinded or conditioned as of the effective time of the Merger Transaction;

•

PBM Capital Finance and Serendipity BioPharma LLC, or Serendipity, shall have executed a Cooperation Agreement, and each RareGen member shall have executed and delivered a lock-up agreement, each as further described below under “The Merger Agreement – Agreements Entered Into in Connection with the Merger Agreement” beginning on page 135; and

•

RareGen shall have cash as of closing equal to at least $1,000,000.

The conditions to the obligations of RareGen to effect the RareGen Merger also include, among other things, the following, subject to certain exceptions and qualifications:

•

we shall have taken all necessary action to ensure that Dr. Jeffs and Mr. Manning shall have been appointed to the HoldCo board of directors as of the effective time of the Merger Transaction.

Many of the conditions to completion of the Merger Transaction are not within either our or RareGen’s control, and neither company can predict when or if these conditions will be satisfied. If any of these conditions are not satisfied or waived prior to December 31, 2020, it is possible that the Merger Agreement may be terminated. Although we and RareGen have agreed in the Merger Agreement to use reasonable best efforts, subject to certain limitations, to complete the merger in the most expeditious manner practicable, these and other conditions to completion of the merger may fail to be satisfied.

The Merger Agreement may be terminated in accordance with its terms and the Merger Transaction may not be completed.

We and RareGen may terminate the Merger Agreement under certain circumstances, including, among other reasons, if the Merger Transaction is not completed by December 31, 2020. In addition, if the Merger Agreement is terminated (i) by us if our board of directors decides to accept a superior proposal or (ii) by RareGen if our board of directors changes its recommendation to our stockholders following receipt of an alternative proposal, then we shall pay to RareGen a termination fee of $7.5 million, as more fully discussed in the section entitled “The Merger Agreement — Termination Fee” beginning on page 134.

In addition, although Neal Fowler, Canaan VIII L.P., Eshelman Ventures, LLC and Fredric N. Eshelman and an additional large institutional investor of our company have agreed to vote their shares of

TABLE OF CONTENTS

our common stock in favor of the approval of the Merger Agreement and the Liquidia Merger, pursuant to separate Support Agreements, this obligation will terminate if the Merger Agreement is validly terminated. See “The Merger Agreement — Agreements Entered Into in Connection with the Merger Agreement: Support Agreements” beginning on page 138 for additional information regarding such agreements.

We may incur substantial transaction fees and merger-related costs in connection with the Merger Transaction.

We expect to incur a number of substantial expenses, totaling approximately $4 million, associated with completing the Merger Transaction, including the costs and expenses of filing, printing and mailing the notice of internet availability of the definitive proxy statement/prospectus and all filing and other fees paid to the SEC and Nasdaq in connection with the Merger Transaction, investment banking fees and expenses, and combining the operations of the two companies. While we have assumed that a certain level of transaction and coordination expenses will be incurred, there are a number of factors beyond our control that could affect the total amount or the timing of these transaction and coordination expenses. Many of the expenses that will be incurred, by their nature, are difficult to estimate accurately. Additional unanticipated costs may be incurred in the integration of the businesses of our company and RareGen, and such costs could become substantial. Although it is expected that the elimination of certain duplicative costs, as well as the realization of other efficiencies related to the integration of the two businesses, will offset the incremental transaction and merger-related costs over time, this net benefit may not be achieved in the near term, or at all. Further, if the Merger Transaction is not completed, we would have to recognize these expenses without realizing the expected benefits of the Merger Transaction. These costs could adversely affect our financial condition and results of operations prior to the Merger Transaction and of HoldCo following completion of the Merger Transaction.

Our stockholders may not realize a benefit from the Merger Transaction commensurate with the ownership dilution they will experience in connection with the Merger Transaction.

If we are unable to realize the strategic and financial benefits currently anticipated from the Merger Transaction, our stockholders will have experienced substantial dilution of their ownership interest without receiving any commensurate benefit. Significant management attention and resources will be required to integrate the two companies. Delays in this process could adversely affect our business, financial results, financial condition and stock price following completion of the Merger Transaction. Even if the combined company were able to integrate the business operations successfully, there can be no assurance that this integration will result in the realization of the full benefits of synergies, innovation and operational efficiencies that may be possible from this integration and that these benefits will be achieved within a reasonable period of time.

We and RareGen will be subject to business uncertainties and contractual restrictions while the Merger Transaction is pending that may cause disruption from the transaction and may make it more difficult to maintain relationships with employees, suppliers, business partners or licensees.

Uncertainties about the effect of the Merger Transaction on employees, suppliers, business partners, licensees and other persons with whom we or RareGen has a business relationship may have an adverse effect on our business or RareGen prior to the Merger Transaction and on HoldCo following completion of the Merger Transaction. In connection with the pendency of the Merger Transaction, as well as during times of significant change and uncertainty such as the period following completion of the Merger Transaction, suppliers, business partners, licensees and other persons with whom we or RareGen have a business relationship may delay or defer business decisions, decide to terminate, modify or renegotiate their relationships with our company or RareGen, or take other actions as a result of the Merger Transaction that could negatively affect our or RareGen’s respective revenues, earnings and cash flows, as well as the market price or fair market value of their respective securities. The ability of us or RareGen to raise additional capital through the debt markets, and the associated borrowing costs, may also be negatively impacted. These disruptions could have an adverse effect on the results of operations, cash flows and financial position of us or RareGen, including an adverse effect on HoldCo’s ability to realize the expected cost savings and other benefits of the Merger Transaction. The risk, and adverse effect, of any disruption could be exacerbated by a delay in completion of the Merger Transaction or termination of the Merger Agreement.

TABLE OF CONTENTS

Employee execution of retention agreements and recruitment of additional employees may be particularly challenging prior to the completion of the Merger Transaction, as employees and prospective employees may experience uncertainty about their future roles with HoldCo. If, despite our or RareGen’s retention and recruiting efforts, key employees depart or prospective key employees fail to accept employment with either company because of issues relating to the uncertainty and difficulty of integration or a desire not to remain with HoldCo, our and RareGen’s financial results could be adversely affected. Furthermore, HoldCo’s operational and financial performance following completion of the Merger Transaction could be adversely affected if it is unable to retain key employees and skilled workers of our company or RareGen. The loss of the services of key employees and skilled workers and their experience and knowledge regarding our or RareGen’s businesses could adversely affect HoldCo’s future operating results and its successful ongoing operation of the business.

During the pendency of the Merger Transaction, we may not be able to enter into a business combination with another party because of restrictions in the Merger Agreement.

Covenants in the Merger Agreement impede our ability to make acquisitions or complete other transactions that are not in the ordinary course of business pending completion of the Merger Transaction, even if such transactions might be favorable to our stockholders. As a result, if the Merger Transaction is not completed, we may be at a disadvantage to our competitors. In addition, while the Merger Agreement is in effect and subject to limited exceptions, we are discouraged from soliciting, initiating, encouraging or taking actions designed to facilitate any inquiries or the making of any proposal or offer that could lead to the entering into certain extraordinary transactions with any third party, such as a strategic collaboration agreement involving LIQ861, or a sale of our assets, an acquisition of our common stock, a tender offer for our common stock, a merger or other business combination outside the ordinary course of business, as the termination of the Merger Agreement of (i) by us if our board of directors decides to accept a superior proposal or (ii) by RareGen if our board of directors changes its recommendation following the receipt of an alternative proposal would result in us paying to RareGen a termination fee of $7.5 million. For more information, see the section entitled “The Merger Agreement — Termination of the Merger Agreement” beginning on page 134.

Because the lack of a public market for the RareGen common units makes it difficult to evaluate the fairness of the Merger Transaction, RareGen’s members may receive consideration in the RareGen Merger that is greater than or less than the fair market value of the RareGen common units.

The outstanding equity of RareGen is privately held and is not traded in any public market. The lack of a public market makes it extremely difficult to determine the fair market value of RareGen. Since the percentage of HoldCo’s common stock to be issued to RareGen’s members was determined based on negotiations between the parties, it is possible that the value of HoldCo’s common stock to be issued in connection with the RareGen Merger will be greater than the fair market value of RareGen. Alternatively, it is possible that the value of the shares of HoldCo common stock to be issued in connection with the RareGen Merger will be less than the fair market value of RareGen.

The combined company will incur significant transaction costs as a result of the Merger Transaction, including investment banking, legal and accounting fees. In addition, the combined company will incur significant consolidation and integration expenses which cannot be accurately estimated at this time, including costs associated with the integration of the RareGen sales force. Actual transaction costs may substantially exceed our estimates and may have an adverse effect on the combined company’s financial condition and operating results.

Failure of the Merger Transaction to qualify as an exchange as described in Section 351 of the Code could adversely affect the RareGen members and our stockholders.

The parties intend for the Merger Transaction to qualify, for U.S. federal income tax purposes, as a transfer described in Section 351 of the Code. For a description of the material U.S. federal income tax consequences of the Merger Transaction to our stockholders, please see the information set forth in the section entitled “Proposal 1 — The Merger Transaction: Material U.S. Federal Income Tax Consequences” beginning on page 114. Each of our stockholders is encouraged to consult such member’s or stockholder’s own tax advisor for a complete understanding of the tax consequences of the Merger Transaction. Certain

TABLE OF CONTENTS

structural and other requirements are required to be satisfied for a transaction to qualify as a transfer described in Section 351 of the Code. We should not recognize taxable gain or loss if the Merger Transaction fails to qualify as an exchange described in Section 351 of the Code. Each Liquidia Technologies U.S. holder would recognize capital gain or loss in an amount equal to the difference between the value of the HoldCo common stock received and the U.S. holder’s tax basis in our common stock exchanged for such HoldCo common stock, if the Merger Transaction fails to qualify as an exchange described in Section 351 of the Code.

The future results of HoldCo will suffer if HoldCo does not effectively manage its expanded operations following the completion of the Merger Transaction.

Following the completion of the Merger Transaction, the size and complexity of the business of HoldCo will increase beyond the current size of either our or RareGen’s business. HoldCo’s future success depends, in part, upon its ability to manage this expanded business, which will pose substantial challenges for management, including challenges related to the management and monitoring of new operations and associated increased costs and complexity. If HoldCo is unsuccessful in managing its integrated operations, or if it does not realize the expected operating efficiencies, cost savings and other benefits currently anticipated from the Merger Transaction, the operations and financial condition of HoldCo could be adversely affected and HoldCo may not be able to take advantage of business development opportunities.

Our internal financial forecasts regarding RareGen may not prove accurate.

In connection with the Merger Transaction, our management prepared internal, stand-alone, pre-transaction financial forecasts of RareGen. These forecasts are based on numerous variables and assumptions that are inherently uncertain and are beyond our control, including assumptions with respect to macro-economic trends, interest rates and anticipated growth rates, and is not necessarily indicative of what RareGen’s actual results of operations, cash flows or financial position would be on the dates indicated. The assumptions used in preparing these forecasts may not prove to be accurate and other factors may affect HoldCo’s actual results and financial condition after the completion of the Merger Transaction, which may cause HoldCo’s actual results and financial condition to differ materially from our estimates contained in the unaudited prospective financial information for RareGen. These forecasts were not prepared with a view to public disclosure, are subject to significant economic, competitive, industry and other uncertainties and may not be achieved in full, at all, or within projected timeframes. The failure of our or RareGen’s businesses to achieve projected results could have a material adverse effect on the price of HoldCo common stock, HoldCo’s financial position, and HoldCo’s operating results and cash flows.

The Merger Transaction may not be accretive and may cause dilution to HoldCo’s earnings per share, which may negatively affect the market price of common stock of HoldCo.

HoldCo could fail to realize all of the benefits anticipated in the Merger Transaction or experience material delays or inefficiencies in realizing such benefits, which could cause dilution to HoldCo’s adjusted diluted earnings per share or decrease or delay the expected accretive effect of the Merger Transaction and cause a decrease in the market value of HoldCo’s common stock.

Any of these factors could negatively impact HoldCo earnings per share or decrease or delay the expected accretive effect of the Merger Transaction and cause a decrease in the market price of common stock of HoldCo.

The Merger Transaction may be completed even though material adverse changes may result from the announcement of the Merger Transaction, industry-wide changes and other causes.

We and RareGen have made representations to each other that there has not been a material adverse change affecting our respective companies and if such representation is not accurate at closing, the other party will not be obligated to complete the Merger Transaction. However, certain types of changes will not constitute a material adverse change, including:

•

any change or condition relating to the economy or securities markets in general, or the industries in which we or RareGen operate in general, and not specifically relating to our company or RareGen;

•

acts of war, armed hostilities or terrorism;

TABLE OF CONTENTS

•

any changes in applicable laws or accounting rules, including accounting principles generally accepted in the United States, or GAAP;

•

any change or condition attributable to the public announcement or pendency of the Merger Agreement or the transactions contemplated by the Merger Agreement, including the loss of customers, suppliers, vendors, lenders, investors, licensors, collaboration partners, employees, other third parties or the performance by us or RareGen of the Merger Agreement;

•

with respect to our company, effects resulting from Hatch-Waxman based litigation relating to LIQ861;

•

geopolitical conditions (including any trade wars), any outbreak, including continuation or expansion of any military conflict, declared or undeclared war, armed hostilities, or acts of foreign or domestic terrorism (including cyber-terrorism);

•

hurricane, flood, tornado, earthquake or other natural disaster or act of God or weather conditions, or any pandemic, epidemic, plague, or other outbreak of illness or public health event;

•

with respect to our company, the failure to meet any internal or external projections or forecasts or any decline in the price of our common stock or changes in the trading volume thereof; and

•

with respect to RareGen, any effects resulting from any litigation and claims subject to the litigation funding and indemnification agreement.

If any of these adverse changes occur and we and RareGen complete the Merger Transaction, HoldCo may suffer.

Risks Related to the Business of HoldCo

HoldCo will need to raise capital after the closing of the Merger Transaction in order to support its operations, which capital may not be available on terms acceptable to HoldCo, or at all.

As of March 31, 2020, we had cash of approximately $40.1 million and RareGen had cash and cash equivalents of approximately $6.0 million. RareGen will distribute all of its cash in excess of $1 million prior to the closing of the Merger Transaction and will have $1 million in cash immediately following the closing. In July 2020, we closed an underwritten public offering pursuant to which we sold 9,375,000 shares of our common stock at a public offering price of $8.00, for total gross proceeds of $75 million, before deducting underwriting discounts and commissions. Following this public offering and the Merger Transaction, HoldCo will likely need to raise substantial additional capital to continue its business operations and remain in compliance with the minimum cash covenant on its debt during and beyond the third quarter of 2021, in addition to commercializing LIQ861, if approved. As a result, HoldCo will need to raise capital after the closing of the Merger Transaction from the sale of debt or equity securities or other sources in order to support its operations. There can be no assurance that HoldCo will be able to obtain this capital on acceptable terms, or at all. If HoldCo issues additional equity or convertible debt securities to raise this capital, your percentage ownership of HoldCo will be reduced, and you may experience significant dilution. In addition, new investors in HoldCo may demand rights, preferences or privileges that differ from, or are senior to, yours, including warrants in addition to the securities purchased and protection against future dilutive transactions.

We have incurred losses over the last few years in excess of RareGen’s operating income, and HoldCo may not be able to achieve profitability.

We have incurred net losses of $14.8 million during the three months ended March 31, 2020 and $47.6 million, $53.1 million and $29.2 million during the years ended December 31, 2019, 2018 and 2017, respectively. We also had negative operating cash flows for each of these periods. As of March 31, 2020 and December 31, 2019, we had an accumulated deficit of $230.0 million and $215.2 million, respectively.

Since our incorporation, we have invested heavily in the development of our product candidates and technologies, as well as in recruiting management and scientific personnel. To date, we have not commenced the commercialization of our product candidates and all of our revenue has been derived from up-front fees and milestone payments made to our company in connection with licensing and collaboration

TABLE OF CONTENTS

arrangements we have entered into. These up-front fees and milestone payments have been, and may continue to be, insufficient to match our operating expenses. We expect to continue to devote substantial financial and other resources to the clinical development of our product candidates and, as a result, must generate significant revenue to achieve and maintain profitability.

RareGen achieved income from operations of $0.4 million in 2019 and RareGen’s future income from operations is not expected to offset our net losses and accumulated deficit for the foreseeable future.

As a result, HoldCo may continue to incur losses and negative cash flow and may never transition to profitability or positive cash flow. Even if HoldCo does achieve profitability, it may not sustain or increase profitability on a quarterly or annual basis in the future. If HoldCo is unable to achieve profitability, it may be forced to implement expense reduction measures, including selling its assets, consolidating its operations, reducing its workforce or delaying, canceling or reducing certain product development, marketing or other operational programs, any of which could harm its business.

Following the closing of the Merger Transaction, HoldCo’s two subsidiaries will be Liquidia Technologies, a late-stage clinical biopharmaceutical company and RareGen, a provider of strategy, investment, and commercialization services and support for rare disease pharmaceutical products, with no approved products and no historical product revenue aside from RareGen’s commercialization of a generic version of Remodulin®, which may make it difficult for you to evaluate HoldCo’s business, financial condition and prospects.

We are a late-stage clinical biopharmaceutical company with no history of commercial operations upon which you can evaluate our prospects. Drug product development involves a substantial degree of uncertainty. Our operations to date have been limited to developing our PRINT technology, undertaking preclinical studies and clinical trials for our product candidates and collaborating with pharmaceutical companies, including GlaxoSmithKline plc and/or its subsidiaries, collectively, GSK, to expand the applications for our PRINT technology through licensing as well as joint product development arrangements. We have not obtained marketing approval for any of our product candidates and, accordingly, have not demonstrated an ability to generate revenue from pharmaceutical products or successfully overcome the risks and uncertainties frequently encountered by companies undertaking drug product development. Consequently, your ability to assess our business, financial condition and prospects may be significantly limited. RareGen provides strategy, investment, and commercialization services and support for rare disease pharmaceutical products, and it has a small, targeted sales force focused on PAH. To date, RareGen’s operations consists entirely of providing services and support relative to the commercialization and marketing of Sandoz’s first-to-file fully substitutable generic version of Remodulin®, a parenteral formulation of treprostinil owned by United Therapeutics and RareGen has a negative income from operations since inception. Further, the net losses that we incur may fluctuate significantly from quarter-to-quarter and year-to-year, such that a period-to-period comparison of our results of operations may not be a good indication of our future performance as a subsidiary of HoldCo. Other unanticipated costs may also arise. Therefore, it may be difficult to evaluate HoldCo’s business, financial condition and prospects as a combined company.

United Therapeutics has initiated a lawsuit against us in which it claims that LIQ861 is infringing three of its patents, which may result in our company being delayed in its efforts to commercialize LIQ861.

We are developing LIQ861 under the 505(b)(2) regulatory pathway with Tyvaso® as the reference listed drug. Accordingly, under the Hatch-Waxman Amendments to the Food, Drug and Cosmetic Act, we were required to, in the NDA for LIQ861, certify that patents listed in the FDA’s Approved Drug Products with Therapeutic Equivalence Evaluations, or the “Orange Book”, for Tyvaso are invalid, unenforceable or will not be infringed by the manufacture, use or sale of LIQ861. Two of these patents are U.S. Patent No. 9,604,901, or the ‘901 patent, entitled “Process to Prepare Treprostinil, the Active Ingredient in Remodulin®”, and U.S. Patent No. 9,593,066, or the ‘066 patent”, entitled “Process to Prepare Treprostinil, the Active Ingredient in Remodulin®”, both of which are owned by United Therapeutics. A notice of the paragraph IV certification was required to be provided to United Therapeutics as the owner of the patents that are the subject of the certification to which the NDA for LIQ861 refers. On June 4, 2020, United Therapeutics, as the holder of such patents, asserted a patent challenge directed to the ‘901 patent and the ‘066 patent by filing a complaint against us in the U.S. District Court for the District of Delaware (Case No. 1:20-cv-00755-UNA), or the Hatch-Waxman Litigation, thereby triggering an automatic 30-month regulatory stay on final approval of the NDA for LIQ861. As a result of United Therapeutics’ patent challenge, the FDA is

TABLE OF CONTENTS

prohibited from approving the NDA for LIQ861 until the earliest to occur of the expiration of the 30-month stay, expiration of the ‘901 patent and ‘066 patent, settlement of the lawsuit or a decision in the infringement suit that is favorable to us as the NDA applicant. Accordingly, we may be subject to significant delay and incur substantial costs in litigation before we are able to commercialize LIQ861, if at all.

On July 21, 2020, the U.S. Patent and Trademark Office, or the USPTO, issued U.S. Patent No. 10,716,793, or the “793 patent”, entitled “Treprostinil Administration by Inhalation”, to United Therapeutics. On July 22, 2020, United Therapeutics filed an amended complaint in the Hatch-Waxman Litigation asserting infringement of the ‘793 patent by the practice of LIQ861. The infringement allegations of the ‘793 patent is separate from the 30-month regulatory stay on final approval of the NDA for LIQ861, which is only associated with the infringement allegations of the ‘901 patent and the ‘066 patent.

On March 30, 2020, we filed two petitions for inter partes review with the Patent Trial and Appeal Board, or the PTAB, of the USPTO. One petition is for inter partes review of the ‘901 patent and a second petition is for inter partes review of the ‘066 patent, both of which are owned by United Therapeutics. We are seeking a determination that the claims in the ‘066 patent and the ‘901 patent are invalid. Both the ‘066 patent and the ‘901 patent are continuation patents to U.S. Patent No. 8,497,393 which was granted to United Therapeutics and subsequently invalidated by the USPTO in an inter partes review instituted in 2016 by SteadyMed Ltd. A determination by the PTAB to institute the petitions is expected early in the fourth quarter of 2020, and final written decisions determining the validity of the challenged claims of the ‘066 patent and the ‘901 patent, if the petitions are instituted by the PTAB, is expected within 12 months from institution.

Our commercial success depends largely on our ability to protect our intellectual property.

Our commercial success depends, in large part, on our ability to obtain and maintain patent protection and trade secret protection in the United States and elsewhere in respect of our product candidates and PRINT technology. If we fail to adequately protect our intellectual property rights, our competitors may be able to erode, negate or preempt any competitive advantage we may have. To protect our competitive position, we have filed and will continue to file for patents in the United States and elsewhere in respect of our product candidates and PRINT technology. The process of identifying patentable subject matter and filing a patent application is expensive and time-consuming. We cannot assure you that we will be able to file the necessary or desirable patent applications at a reasonable cost, in a timely manner, or at all. Further, since certain patent applications are confidential until patents are issued, third parties may have filed patent applications for subject matters covered by our pending patent applications without us being aware of such applications, and our patent applications may not have priority over patent applications of others. In addition, we cannot assure you that our pending patent applications will result in patents being obtained. Once published, all patent applications and publications throughout the world, including our own, become prior art to our new patent applications and may prevent patents from being obtained or interfere with the scope of patent protection that might be obtained. The standards that patent offices in different jurisdictions use to grant patents are not always applied predictably or uniformly and may change from time to time.

Even if we have been or are able to obtain patent protection for our product candidates or PRINT technology, if the scope of such patent protection is not sufficiently broad, we may not be able to rely on such patent protection to prevent third parties from developing or commercializing product candidates or technology that may copy our product candidates or technology. The enforceability of patents in the pharmaceutical industry involves complex legal and scientific questions and can be uncertain. Accordingly, we cannot assure you that third parties will not successfully challenge the validity, enforceability or scope of our patents. A successful challenge to our patents may lead to generic versions of our drug products being launched before the expiry of our patents or otherwise limit our ability to stop others from using or commercializing similar or identical products and technology. A successful challenge to our patents may also reduce the duration of the patent protection of our drug products or technology. If any of our patents are narrowed or invalidated, our business and prospects may be materially and adversely affected. In addition, we cannot assure you that we will be able to detect unauthorized use or take appropriate, adequate and timely actions to enforce our intellectual property rights. If we are unable to adequately protect our intellectual property, our business, competitive position and prospects may be materially and adversely affected.

TABLE OF CONTENTS

Even if our patents or patent applications are unchallenged, they may not adequately protect our intellectual property or prevent third parties from designing around our patents or other intellectual property rights. If the patent applications we file or may file do not lead to patents being granted or if the scope of any of our patent applications is challenged, we may face difficulties in developing our product candidates, companies may be dissuaded from collaborating with us, and our ability to commercialize our product candidates may be materially and adversely affected. We are unable to predict which of our patent applications will lead to patents or assure you that any of our patents will not be found invalid or unenforceable or challenged by third parties. The patents of others may prevent the commercialization of product candidates incorporating our technology. In addition, given the amount of time required for the development, clinical testing and regulatory review of new product candidates, any patents protecting our product candidates may expire before or shortly after such product candidates might become approved for commercialization.

Moreover, the issuance of a patent is not conclusive as to the inventorship of the patented subject matter, or its scope, validity or enforceability. We cannot assure you that all of the potentially relevant prior art, that is, any evidence that an invention is already known, relating to our patents and patent applications, has been found. If such prior art exists, it may be used to invalidate a patent or may prevent a patent from being issued.

In addition, we, our collaborators or our licensees may fail to identify patentable aspects of inventions made in the course of development and commercialization activities before it is too late to obtain patent protection on them. As a result, we may miss potential opportunities to seek patent protection or strengthen our patent position.

HoldCo’s management, which is substantially similar to our management, has broad discretion in using the net proceeds from prior public and private equity offerings and may not use them effectively.

HoldCo’s management expects to use the net proceeds of July 2020 public offering and prior public and private equity offerings for ongoing commercial development of LIQ861, for continued development of LIQ865 and for general corporate purposes. The net proceeds are not being used to fund the acquisition of RareGen and we do not expect to use any material proceeds from this offering to fund the operations of RareGen. HoldCo’s management has broad discretion in the application of such proceeds and could spend the proceeds in ways that do not improve HoldCo’s results of operations or enhance the value of its equity. The failure by HoldCo’s management to apply these funds effectively could result in financial losses that could have a material adverse effect on HoldCo’s business, diminish cash flows available to service its debt, cause the value of its equity to decline and delay the development of its product candidates. Pending their use, HoldCo may invest such proceeds in short-term, investment-grade, interest-bearing securities, which may not yield favorable returns.

Disruptions at the FDA and other government agencies could hinder their ability to hire and retain key leadership and other personnel, prevent new products and services from being developed or commercialized in a timely manner or otherwise prevent those agencies from performing normal business functions on which the operation of HoldCo’s business may rely, which could negatively impact HoldCo’s business.

The ability of the FDA to review and approve new products can be affected by a variety of factors, including global pandemics, natural disasters, geopolitical actions, government budget and funding levels, ability to hire and retain key personnel and accept the payment of user fees, and statutory, regulatory, and policy changes. Average review times at the FDA have fluctuated in recent years as a result. In addition, government funding of other government agencies on which our operations may rely, including those that fund research and development activities, is subject to the political process, which is inherently fluid and unpredictable.

Disruptions at the FDA and other agencies may also slow the time necessary for new drugs to be reviewed and/or approved by necessary government agencies, which would adversely affect our business. For example, in December 2019, a novel strain of COVID-19, or coronavirus, was reported to have surfaced in Wuhan, China and has become a global pandemic as of the date of this proxy statement/prospectus. The full impact of the coronavirus is unknown and rapidly evolving. For example, after generally suspending in-person inspections due to COVID-19, the FDA recently announced it would resume domestic facility

TABLE OF CONTENTS

inspections, although the agency continues its general suspension of foreign facility inspections (although “mission-critical” inspections may be considered on a case-by-case basis). Because of the global pandemic, decision-making around facility inpsections by the FDA (including preapproval inspections) continues to evolve. Additionally, over the last several years, including from December 22, 2018 until January 25, 2019, the U.S. government has shut down several times and certain regulatory agencies, such as the FDA, have had to furlough critical FDA and other government employees and stop critical activities. If a prolonged government disruption occurs, it could significantly impact the ability of the FDA to timely review and process HoldCo’s regulatory submissions, which could have a material adverse effect on its business. Further, in HoldCo’s operations as a public company, prolonged government disruptions, global pandemics and other natural disasters or geopolitical actions could impact its ability to access the public markets and obtain necessary capital in order to properly capitalize and continue its operations.

HoldCo will depend upon third parties for materials and components necessary for both clinical and commercial production of LIQ861, including single suppliers for the active ingredient, the device, encapsulation and packaging of LIQ861.

We depend on third-party suppliers for the supply of materials and components necessary for clinical and commercial production of LIQ861, including the active pharmaceutical ingredients which are used in our product candidates. These supplies may not always be available to us at the standards we require or on terms acceptable to us, or at all, and we may not be able to locate alternative suppliers in a timely manner, or at all. If we are unable to obtain necessary clinical or commercial supplies, our manufacturing operations and clinical trials and the clinical trials of our collaborators, and our plans for commercial production may be delayed or disrupted and our business and prospects may be materially and adversely affected as a result.

For example, we currently rely on a sole supplier for treprostinil, the active pharmaceutical ingredient of LIQ861, which sources treprostinil from a manufacturer in South Korea. If our supplier is unable to supply treprostinil to us in the quantities we require, or at all, or otherwise default on its supply obligations to us, or if it ceases its relationship with us, we may not be able to obtain alternative supplies of treprostinil from other suppliers on acceptable terms, in a timely manner, or at all. Furthermore, LIQ861 is administered using the RS00 Model 8 DPI, or dry powder inhaler, which is manufactured by Plastiape S.p.A., or Plastiape, which is located in Italy. We also rely on a sole supplier for encapsulation and packaging services. We purchase treprostinil, our DPI supply and encapsulation and packaging services pursuant to purchase orders and do not have long-term contracts with these suppliers. In the event of any prolonged disruption to our supply of treprostinil, the manufacture and supply of RS00 Model 8 DPI or encapsulation and packaging services, our ability to develop and commercialize, and the timeline for commercialization of, LIQ861 may be adversely affected.

Additionally, in December 2019, a novel strain of COVID-19, or coronavirus, was reported to have surfaced in Wuhan, China and has become a global pandemic as of the date of this proxy statement/prospectus. The full impact of the coronavirus is unknown and rapidly evolving. Both South Korea, the country from which our supplier sources treprostinil, and Italy, the country in which Plastiape is headquartered, have had significant outbreaks of this disease, which, in the case of Italy, led to a lockdown of the entire country. The extent to which the coronavirus impacts our ability to procure sufficient materials and components for the development and commercialization of our products and product candidates (or for pre-approval inspections, if required in order for FDA to obtain sufficient assurance or verification of compliance with good manufacturing practice regulations) will depend on the severity, location and duration of the spread of the coronavirus, and the actions undertaken to contain the coronavirus or treat its effects.

We and RareGen depend on skilled labor, and HoldCo’s business and prospects may be adversely affected if it loses the services of its skilled personnel, including those in senior management, or is unable to attract new skilled personnel.

HoldCo’s ability to continue our and RareGen’s operations following completion of the Merger Transaction and manage its potential future growth depends on its ability to hire and retain suitably skilled and qualified employees, including those in senior management, in the long-term. Due to the specialized nature of our and RareGen’s work, there is a limited supply of suitable candidates. We and RareGen compete with other biotechnology and pharmaceutical companies, educational and research institutions and government entities, among others, for research, technical and clinical personnel. In addition, in order

TABLE OF CONTENTS

to manage its potential future growth effectively, HoldCo will need to improve its financial controls and systems and, as necessary, recruit sales, marketing, managerial and finance personnel. If HoldCo is unable to attract and retain skilled personnel, including in particular Neal Fowler, its Chief Executive Officer, its business and prospects may be materially and adversely affected.

We reported material weaknesses in internal control over financial reporting for the year ended December 31, 2019 and quarter ended March 31, 2020, and HoldCo cannot assure you that additional material weaknesses will not be identified in the future. Additionally, as a private company, RareGen’s internal controls over financial reporting will need to be upgraded to the level of a Sarbanes-Oxley compliant company. HoldCo’s failure to implement and maintain effective internal control over financial reporting could result in material misstatements in HoldCo’s financial statements, which could require HoldCo to restate its financial statements, cause investors to lose confidence in HoldCo’s reported financial information and have a negative effect on HoldCo’s stock price.

Effective internal controls over financial reporting are necessary for public companies to provide reliable financial reports and, together with adequate disclosure controls and procedures, are designed to prevent fraud. Any failure to implement required new or improved controls, or difficulties encountered in their implementation could cause HoldCo to fail to meet its reporting obligations. Inferior internal controls could also cause investors to lose confidence in our reported financial information, which could have a negative effect on the trading price of HoldCo common stock. In addition, any future testing by HoldCo conducted in connection with Section 404 of the Sarbanes-Oxley Act of 2002, as amended, or the Sarbanes-Oxley Act, or the subsequent testing by HoldCo’s independent registered public accounting firm, may reveal deficiencies in its internal controls over financial reporting that are deemed to be material weaknesses or that may require prospective or retroactive changes to our financial statements or identify other areas for further attention or improvement.

As required by the Sarbanes Oxley Act and commencing with the fiscal year ended December 31, 2019, we are required to furnish a report by management on, among other things, the effectiveness of its internal controls over financial reporting, or ICFR, for the fiscal year ended December 31, 2019. In connection with the assessment of the effectiveness of its ICFR, our management identified the following material weaknesses that existed as of December 31, 2019:

During 2019, we experienced significant turnover in finance personnel that reduced the complement and skill of the resources within our company. As a result, we did not maintain an effective control environment as we lacked a sufficient complement of resources with an appropriate level of knowledge, experience and training to design, maintain and monitor our ICFR commensurate with our financial reporting requirements. As a result, this material weakness contributed to the following material weaknesses:

•

We did not design and maintain controls to ensure adequate segregation of duties within our financial reporting function, including the preparation and review of journal entries. Specifically, some key accounting personnel had the ability to both prepare and post journal entries without an independent review by someone without the ability to prepare and post journal entries.

•

We did not design and maintain effective controls over certain information technology general controls for information systems that are relevant to the preparation of its financial statements. Specifically, we did not design and maintain effective user access controls to ensure appropriate segregation of duties and that adequately restrict user and privileged access to financial applications and data to appropriate Liquidia Technologies personnel.

These material weaknesses did not result in a material misstatement of our annual or interim financial statements for 2019. Additionally, these material weaknesses could result in a misstatement of the relevant account balances or disclosures that would result in a material misstatement to the annual or interim consolidated financial statements that would not be prevented or detected.

Additionally, HoldCo could be subject to regulatory scrutiny, a loss of public and investor confidence, and to litigation from investors and stockholders, all of which could have a material adverse effect on its business and the trading price of its shares. Subsequent to our December 31, 2019 year end, we began taking a number of actions, including designing and implementing new controls and revising existing controls, in order to remediate the material weaknesses described above. To that end, we have engaged a large accounting

TABLE OF CONTENTS

firm to assist us with the remediation efforts. Failure to remedy any material weakness in our internal control over financial reporting, or to implement or maintain other effective control systems required of public companies, could result in charges by the SEC with violating the books and records and internal control provisions of the federal securities laws which may result in penalties and fines to HoldCo or its or its subsidiaries’ directors and officers, and also could restrict our future access to the capital markets.

RareGen, as a private company, is not subject to Sarbanes-Oxley and, as such, following the closing of the Merger Transaction its internal controls over financial reporting will need to be built and/or upgraded, which could be time-consuming and expensive. For example, RareGen’s controls and processes will need to be formalized and HoldCo will need to build an internal finance function to support RareGen. The controller at PBM Capital Group currently acts as RareGen’s Chief Financial Officer and otherwise supports RareGen’s financial infrastructure needs. The acquisition of RareGen could also hinder HoldCo’s efforts to remediate its material weaknesses as management will need to devote substantial efforts and resources towards consummating the Merger Transaction, syncing Liquidia’s and RareGen’s businesses and implementing and upgrading ICFR for RareGen.

For as long as we and HoldCo are an “emerging growth company” under the Jumpstart Our Business Startups Act of 2012, as amended, or the JOBS Act, its independent registered public accounting firm will not be required to attest to the effectiveness of the issuer’s internal controls over financial reporting pursuant to Section 404. We or HoldCo, as our successor, could be an emerging growth company for up to an additional three years. An independent assessment of the effectiveness of the issuer’s internal controls could detect additional problems that its management’s assessment might not. Undetected material weaknesses in our internal controls could lead to financial statement restatements and require us or HoldCo to incur additional remediation expenses.

HoldCo’s ability to use net operating losses to offset future taxable income will be subject to certain limitations.

In general, under Section 382 of the Code, a corporation that undergoes an “ownership change” is subject to limitations on its ability to utilize its pre-change net operating losses to offset future taxable income. A corporation generally undergoes an “ownership change” if the percentage of stock of the corporation owned by one or more of its 5% stockholders has increased by more than 50 percentage points over a three-year period.

Our existing net operating losses currently are subject to limitations arising from previous ownership changes and will be subject to additional limitations as a result of the Merger Transaction. In addition, if HoldCo undergoes an ownership change after the Merger Transaction, the combined company’s ability to utilize NOLs could be further limited by Section 382 of the Code. It is impossible for HoldCo to ensure that it will not experience an ownership change in the future because changes in its stock ownership, some of which are outside of HoldCo’s control, could result in an ownership change under Section 382 of the Code.

Generally, the limitations on HoldCo’s ability to use our pre-Merger Transaction NOLs to offset future taxable income are expected to be significant, and thus, HoldCo’s liability for future U.S. federal income taxes may be materially higher than that liability would have been absent such limitations. Similar rules may apply for foreign and state income tax purposes as well.

Risks Related to the Business of RareGen

RareGen does not hold the FDA regulatory approval for the Product and is dependent on Sandoz to manufacture and supply the Product in compliance with FDA requirements, and is more broadly dependent on Sandoz’s FDA and healthcare compliance relative to the Product.

Sandoz holds the FDA approval (the ANDA) for and controls the Product and is responsible among other things for the compliant manufacture, distribution, labeling, and advertising of the Product. RareGen’s role is one of a specialized service provider to Sandoz. As a result, RareGen is dependent on Sandoz to manufacture and supply the Product, and dependent on Sandoz for the continued FDA compliance of the Product. RareGen does not have control over Sandoz’s compliance with laws and regulations applicable to drug manufacturers and ANDA holders (for example, applicable current good manufacturing practices (GMPs); FDA labeling, promotional labeling, and advertising requirements; pharmacovigilance and adverse

TABLE OF CONTENTS

event reporting; and other ongoing FDA reporting and submission requirements), nor over its compliance with healthcare compliance and fraud, waste, and abuse laws, or similar regulatory requirements and other laws and regulations, such as those related to environmental health and safety matters. In addition, RareGen has no control over the ability of Sandoz to maintain adequate quality control, quality assurance and qualified personnel, or other personnel with roles related to the regulatory compliance of the Product and its labeling, promotion, and advertising or of Sandoz’s activities in relation to government healthcare programs. If the FDA or a comparable foreign regulatory authority finds deficiencies with the manufacture or quality assurance of the Product or identifies safety or efficacy concerns related to the Product, or if Sandoz otherwise is unable to comply with applicable laws, regulations and standards, Sandoz’s ability to manufacture, sell and supply the Product could be limited, which would cause an adverse effect on RareGen’s business, financial condition and results of operations.

Sandoz’s ability to consistently manufacture and supply the Product in a timely manner may also be interrupted by production shortages or other supply interruptions, including as a result of the ongoing COVID-19 pandemic. RareGen’s share of net profits under the Promotion Agreement is reduced by certain manufacturing costs and other write-offs related to Sandoz’s inability to sell the Product, including in the event that the Product expires prior to sale. Currently, the Product expires 24 months after the date of manufacture. If Sandoz’s manufacturing costs increase, or its ability to sell the Product within 24 months of the date of manufacture is interrupted, there would be an adverse effect on RareGen’s business, financial condition and results of operations.

RareGen’s ability to sell the Product is dependent on market acceptance of generic treprostinil for parenteral administration by patients, health care providers and by third-party payors, while interactions with these persons and entities are subject to compliance requirements.

RareGen’s ability to sell the Product is dependent on market acceptance of generic treprostinil for parenteral administration by patients, health care providers and by third-party payors. If the Product does not achieve an adequate level of acceptance, RareGen may not generate sufficient revenue to remain profitable.

At the same time, arrangements with healthcare providers, physicians, third-party payors and customers, and RareGen’s sales, marketing and educational activities, may expose it to broadly applicable fraud and abuse and other healthcare laws and regulations that may constrain its business or financial arrangements and relationships.

The degree of market acceptance of the Product will depend on a number of factors, including:

•

the efficacy, safety and potential advantages compared to alternative treatments;

•

RareGen’s ability to offer the Product for sale at competitive prices;

•

the convenience and ease of administration compared to alternative treatments;

•

whether the Product may be administered subcutaneously;

•

product labeling or product insert requirements of the FDA or foreign regulatory authorities, including any limitations or warnings contained in a product’s approved labeling, including any black box warning;

•

the willingness of the target patient population to try new treatments, including the generic version of a brand, and of physicians to prescribe such treatments;

•

RareGen’s ability to hire and retain sales and marketing personnel and their ability to support Sandoz under RareGen’s Promotion Agreement;

•

the strength of Sandoz’s manufacturing and distribution support;

•

the requirement by third-party payors to use generic treprostinil for parenteral administration in place of Remodulin®;

•

the availability of third-party coverage and adequate reimbursement for the Product;

•

the prevalence and severity of any side effects;

•

any restrictions on the use of the Product together with other medications; and

TABLE OF CONTENTS

•

the services provided by specialty pharmacies related to use of the Product.

RareGen’s business may also be impacted by the need to maintain compliant operations (including oversight and monitoring of personnel and their activities) in relation to interactions with the persons and parties noted above, relative to FDA and healthcare law requirements.

RareGen faces substantial competition, which may result in a smaller than expected commercial opportunity.

RareGen faces substantial competition. Even though Sandoz launched the first-to-file fully substitutable generic treprostinil for parenteral administration in March 2019 that is sold primarily through the specialty pharmacies, Teva Pharmaceutical Industries Ltd. launched a generic treprostinil for parenteral administration in October 2019 that is sold primarily through a specialty pharmacy and to hospitals, Par Pharmaceutical, Inc. launched a generic treprostinil for parenteral administration after receiving approval in September 2019 that is sold primarily to hospitals, Dr. Reddy’s Laboratories Inc.’s received approval in May 2020 for generic treprostinil for parenteral administration, and Alembic Pharmaceuticals Ltd’s has settled with United Therapeutics in order to launch a generic treprostinil for parenteral administration, though it has not yet been approved to date. Such increased competition may result in a smaller than expected commercial opportunity for RareGen.

Generic drug prices may, and often do, decline, sometimes dramatically, especially as additional generic pharmaceutical companies (including low-cost generic producers outside of the United States) receive approvals and enter the market for a given product. The goals established under the Generic Drug User Fee Act, and increased funding of the FDA’s Office of Generic Drugs, have led to more and faster generic approvals, and consequently increased competition for generic products. The FDA has stated that it has established new steps to enhance competition, promote access and lower drug prices and is approving record-breaking numbers of generic applications. The FDA’s changes may benefit RareGen’s competitors. RareGen’s ability to sell the Product and earn revenue is affected by the number of companies selling competitive products, including new market entrants, and the timing of their approvals.

Furthermore, branded pharmaceutical companies such as United Therapeutics continue to defend their products vigorously through, among other actions, life cycle management, marketing agreements with third-party payors, pharmacy benefits managers and generic manufacturers. These actions add increased competition in the generic pharmaceutical industry, including competition for the Product.

Many of the companies against which RareGen competes, or against which RareGen may compete in the future, including United Therapeutics, have significantly greater financial resources than does RareGen. Mergers and acquisitions in the pharmaceutical and biotechnology industries may result in even more resources being concentrated among a smaller number of our competitors. Smaller companies may also prove to be significant competitors, particularly through collaborative arrangements with large and established companies. These competitors may also compete with RareGen in recruiting and retaining qualified sales personnel.

RareGen’s future success depends on its ability to attract, retain and motivate qualified sales personnel, with experience specific to the pharmaceutical industry and relevant disease area.

RareGen is highly dependent on the expertise of its sales personnel. Each member of its sales team may terminate his or her employment with RareGen at any time. RareGen does not maintain “key person” insurance for any of its employees.

Recruiting and retaining qualified sales and marketing personnel is critical to RareGen’s success. The loss of the services of members of RareGen’s sales team could seriously harm its ability to successfully implement its business strategy. Furthermore, replacing sales personnel may be difficult and may take an extended period of time because of the limited number of individuals in RareGen’s industry with the breadth of skills and experience required to successfully sell and market products such as treprostinil. Competition to hire from this limited pool is intense, and RareGen may be unable to hire, train, retain or motivate these key personnel on acceptable terms given the competition among numerous pharmaceutical and biotechnology companies for similar personnel. If RareGen is unable to continue to attract and retain high quality sales personnel, its ability to pursue its growth strategy will be limited.

TABLE OF CONTENTS

Medical devices, which RareGen does not control, are necessary for the administration of the Product.

In order for the Product to be administered with patients, patients must use certain other medical equipment, including pumps, cartridges and infusion sets. RareGen does not manufacture or control such medical equipment, which is manufactured by third parties and owned and dispensed by specialty pharmacies, hospitals or other third parties. RareGen’s ability to serve patients is dependent upon the ability of specialty pharmacies to maintain sufficient inventory of such medical equipment to provide to patients. If manufacturers cease to manufacture or support medical equipment or if specialty pharmacies are unable to obtain or maintain sufficient inventories of such medical equipment, RareGen’s sales may be adversely impacted.

RareGen is seeking to work with third parties to develop or procure pumps and cartridges that can be used to administer the Product. Such pumps and cartridges may require FDA 510(k) clearance before they can be sold. There is no guarantee that RareGen or a third party will receive FDA 510(k) clearance. Failure by RareGen or third parties to successfully develop or supply the medical equipment or to obtain or maintain regulatory approval or clearance of such medical equipment could negatively impact the market acceptance of and sales of the Product.

RareGen must comply with various laws in jurisdictions around the world that restrict certain marketing practices in the pharmaceutical and medical device industries. Failure to comply with such laws could result in penalties and have a material adverse effect on RareGen’s business, financial condition and results of operations.

RareGen’s business activities may be subject to challenge under laws in jurisdictions around the world restricting particular marketing practices, such as among others, anti-kickback and various false claim statutes, the Foreign Corrupt Practices Act and the United Kingdom Bribery Act. Any penalties imposed upon RareGen for failure to comply could have a material adverse effect on its business and financial condition.

In the United States, the Federal Anti-Kickback Statute prohibits, among other activities, knowingly and willfully offering, paying, soliciting, or receiving compensation to induce, or in return for, the purchase, lease, order or arranging the purchase, lease or order of any health care product or service reimbursable under any federally financed health-care program. This statute has been interpreted broadly to apply to arrangements between pharmaceutical manufacturers and prescribers, purchasers, formulary managers, patients, and others. The exemptions and safe harbors under this statute may be narrow, and practices that involve compensation may be subject to scrutiny if they do not qualify for an exemption or safe harbor.

The Federal False Claims Act, as amended by the PPACA, prohibits any person from presenting or causing to be presented a false or fraudulent claim or making or causing a false statement material to a false or fraudulent claim. For example, several pharmaceutical and health care companies have been investigated under this law for allegedly providing free product to customers with the expectation that the customers would bill federal health care programs for the free product. Other companies have been prosecuted for causing false claims to be submitted because of these companies’ marketing of a product for unapproved, or “off-label”, and non-reimbursable uses. Potential liability under the Federal False Claims Act includes mandatory treble damages and significant per-claim penalties. The majority of states also have statutes similar to the Federal Anti-Kickback Statute and the Federal False Claims Act. Sanctions under these federal and state laws may include treble civil monetary penalties, exclusion of a manufacturer’s product from reimbursement under state government programs, debarment, criminal fines, additional reporting requirements and regulatory oversight and imprisonment.

Although federal enforcement is most commonly directed toward those actors who file or cause to be filed claims for reimbursement, both parties to certain sales and marketing transactions are equally liable. Enforcement trends change periodically, and RareGen may receive governmental inquiries into the nature of its sales and marketing arrangements. Such investigations or reviews could result in punitive enforcement including fines and penalties, reputational damage, and market loss.

The U.S. Physician Payments Sunshine Act established reporting requirements for certain pharmaceutical, biologic and device manufacturers, or “applicable manufacturers”, regarding direct and indirect payments or other transfers of value made to physicians and teaching hospitals, as well as reporting of investment interests in such manufacturers held by physicians and their immediate family members

TABLE OF CONTENTS

during the preceding calendar year. Failure to submit required information may result in civil monetary penalties, which may increase significantly for “knowing failures.” In 2022, the Sunshine Act will be extended to payments and transfers of value to physician assistants, nurse practitioners, and other mid-level practitioners (with reporting requirements going into effect in 2022 for payments made in 2021). These laws are relevant to companies providing sales and marketing services on behalf of “applicable manufacturers,” for example, resulting in the need to track and report certain information to the applicable manufacturer, to allow the applicable manufacturer to meet its obligation under the law. In addition, Section 6004 of the ACA requires annual reporting of information about drug samples that manufacturers and authorized distributors provide to healthcare providers. A number of states have also implemented laws relevant to the licensure or registration of pharmaceutical sales representatives, as well as other laws addressing compliance program expectations, transparency regarding sales and marketing activities and prohibitions or restrictions on certain financial arrangements or activities. Tracking, assessing, and complying with laws which may apply on a state-by-state basis can be challenging and time consuming.

Because of the breadth of these laws and the narrowness of the statutory exceptions and safe harbors available under such laws, it is possible that certain business activities could be subject to challenge under one or more of such laws. The scope and enforcement of each of these laws is uncertain and subject to rapid change in the current environment of healthcare reform, especially in light of the lack of applicable precedent and regulations. Federal and state enforcement bodies have recently increased their scrutiny of interactions between healthcare companies and healthcare providers, which has led to a number of investigations, prosecutions, convictions and settlements in the healthcare industry. Ensuring that business arrangements with third parties comply with applicable healthcare laws, as well as responding to possible investigations by government authorities, can be time- and resource-consuming and can divert management’s attention from the business.

Government healthcare reform and other reforms could adversely affect RareGen’s revenue, costs and results of operations.

RareGen provides services within the pharmaceutical industry, which is highly regulated by federally funded healthcare programs and, therefore, subject to those programs’ controls of pricing, rebates, and marketing. In recent years, there have been numerous initiatives on the federal and state levels in the United States for comprehensive reforms affecting the marketing, payment for, the availability of and reimbursement for healthcare services. For example, Congress and many states have proposed legislation that seeks to indirectly or directly regulate pharmaceutical drug pricing by requiring drug manufacturers to publicly report proprietary pricing information or to place a maximum price ceiling on pharmaceutical products purchased by state agencies. At least five relevant bills have been introduced in Congress since 2019, and H.R. 3 passed in the House. Current and future U.S. legislative healthcare reforms and the recent Executive Orders issued in July 2020 by the President on drug pricing, may result in price and marketing controls and other restrictions for any approved products, if covered, and could adversely impact RareGen’s business.

In addition, rebate policies could allow state Medicaid programs to request additional supplemental rebates on the Product as a result of the increase in the federal base Medicaid rebate. Private insurers could also use the enactment of any federal policies to exert pricing pressure on the Product, and to the extent that private insurers or managed care programs follow Medicaid coverage and payment developments, the adverse effects may be magnified by private insurers adopting lower payment schedules.

The COVID-19 pandemic is affecting the delivery model and coverage parameters for some prescription drugs. In April 2020, HHS published an interim final rule that expanded the permissible circumstances for administering some drugs to increase access to care as patients avoid office visits. In some instances, coverage for Part B drugs could potentially be shifted from Part D, which affects reimbursement rates and copayment obligations. Similarly, HPMS Memo (Mar. 10, 2020) authorizes Part D sponsors to loosen refill restrictions, allow reimbursement for out-of-network pharmacies, permit home and mail delivery of prescription drugs, and waive prior authorization requirements. The effect of these waivers on pricing, distribution, and sales volume is still uncertain. It is unknown how long the emergency and pandemic declarations will remain in effect, whether all of these measures will be extended past the current emergency, or whether COVID-19 will result in any other material or long-term effects on the market.

TABLE OF CONTENTS

The Patient Protection and Affordable Care Act of 2010 (Pub.L. 111-148) and the Health Care and Education Reconciliation Act of 2010 (Pub.L 111-152, 124 Stat. 1029), as amended and collectively known as the ACA, is a broad measure intended to expand health care coverage within the United States and introduce additional measures to protect the integrity of federally funded health programs. The 21st Century Cures Act of 2016 (Pub.L. 114-255), meanwhile, contains a wide range of provisions designed to promote clinical research and streamline and expedite the FDA review and approval process. The reforms imposed by these laws significantly impact the pharmaceutical industry. The ACA, however, remains subject to pending legal and constitutional challenges in the United States Supreme Court. California, et al v. Texas, et al, Cause No. 19-840. The full effects of the ACA and the 21st Century Cures Act may be unknown until all outstanding legal issues are resolved, the statutory provisions are fully implemented, and CMS, the FDA, and other federal and state agencies issue final applicable regulations or guidance. RareGen may also face uncertainties as a result of federal executive, Congressional and administrative efforts to repeal, substantially modify or invalidate some or all of the relevant provisions of the ACA.

Moreover, in the coming years, additional changes could be made to governmental health care programs or FDA regulations that could significantly impact the success of the Product. There is no assurance that the ACA and other laws, as currently enacted or as amended in the future, will not adversely affect RareGen’s business and financial results, and RareGen cannot predict how future federal or state legislative, regulatory, or administrative changes related to healthcare reform will affect its business. The future stability of applicable laws and regulations, and the resulting impact on RareGen’s business is thus uncertain and could be material.

The successful commercialization of the Product depends on a variety of factors, including the extent to which drug prices are scutinized and potentially limited, and governmental authorities and health insurers establish adequate coverage and reimbursement levels for the Product.

In recent years, there have been numerous initiatives on the federal and state levels in the United States for a broad range of reforms regarding the pricing of pharmaceutical products, limiting coverage and reimbursement for drugs and other medical products, increasing transparency regarding pricing, and otherwise addressing government control and other changes to the healthcare system in the United States. Specifically, there have been several United States Congressional inquiries and proposed and enacted federal and state legislation designed to, among other things, bring more transparency to drug pricing, reduce the cost of prescription drugs under Medicare, review the relationship between pricing and manufacturer patient programs, and reform government program reimbursement methodologies for drugs.

Some states have implemented, and other states are considering, pharmaceutical price controls or patient access constraints under the Medicaid program, and some states are considering price-control regimes that would apply to broader segments of their populations that are not Medicaid-eligible. There have also been recent state legislative efforts to address drug costs, which generally have focused on increasing transparency around drug costs or limiting drug prices. Efforts by government officials or legislators to implement measures to regulate prices or payments for pharmaceutical products, including legislation on drug importation, could adversely affect our business if implemented.

Successful sales of the Product depend, in part, on the extent to which coverage and reimbursement for the Product is available from government and health administration authorities, private health insurers and other third-party payors. To manage healthcare costs, many governments and third-party payors increasingly scrutinize the pricing of drug products and require increasing levels of evidence of favorable clinical outcomes and cost-effectiveness before extending coverage. If the Product is unable to obtain coverage and adequate levels of reimbursement from third party payors, the commercial success and marketability will be negatively and materially impacted.

Risks Relating to the Ownership of HoldCo Common Stock

An active trading market for HoldCo common stock may not be sustainable. If an active trading market is not sustained, HoldCo’s ability to raise capital in the future may be impaired.

We completed our initial public offering in July 2018. Prior to this time, there was no public market for our common stock. Although HoldCo’s common stock will be listed on the Nasdaq Capital Market following

TABLE OF CONTENTS

completion of the Merger Transaction, an active trading market for its shares may not be sustained. If an active market for HoldCo common stock is not sustained, it may be difficult for you to sell shares of HoldCo common stock without depressing the market price for the shares or at all. An inactive trading market may also impair HoldCo’s ability to raise capital to continue to fund operations by selling shares and may impair HoldCo’s ability to acquire other companies or technologies by using our shares as consideration.

Holders of our common stock will have a reduced ownership and voting interest after the Merger Transaction and will exercise less influence over management.

Holders of our common stock currently have the right to vote in the election of the board of directors and on other matters affecting our company. Upon the completion of the Merger Transaction, each Liquidia Technologies stockholder who receives shares of HoldCo common stock will become a stockholder of HoldCo with a percentage ownership of HoldCo that is smaller than the stockholder’s percentage ownership of our company. It is currently expected that our stockholders as a group ((excluding, for this purpose, shares of HoldCo common stock to be received by current RareGen members, or known affiliates of RareGen members, who are holders of our common stock) will receive shares in the Merger Transaction constituting approximately 86.0% of the shares of HoldCo common stock immediately after the Merger Transaction (assuming for this purposes that all 616,666 of the Holdback Shares are distributed to RareGen members on March 31, 2022), or approximately 80.9% of the shares of HoldCo common stock immediately after the Merger Transaction assuming a maximum of 2,708,333 Net Sales Earnout Shares are issued to current RareGen members in 2022. Because of this, our stockholders will have less influence on the management and policies of HoldCo than they now have on the management and policies of our company.

If the proposed Merger Transaction is consummated, future sales of HoldCo’s common stock in the public market could cause HoldCo’s stock price to fall.

Upon consummation of the Merger Transaction, HoldCo will issue to RareGen’s members an aggregate of 6,166,666 shares of HoldCo common stock, including 616,666 shares of HoldCo common stock, which are referred to in the Merger Agreement as “Holdback Shares” which are being withheld to satisfy potential indemnification obligations of RareGen members. In addition, HoldCo will issue up to 2,708,333 shares of HoldCo common stock in 2022, which are referred to in the Merger Agreement as “Net Sales Earnout Shares”, if RareGen achieves at least $32.9 million of 2021 net sales (as calculated by Sandoz net sales), with the number of Net Sales Earnout Shares to be issued to depend upon the actual amount of the 2021 net sales. For more information, see “Proposal 1 — The Merger Transaction: The Merger Consideration and Conversion of Securities” on page 110. The shares issued to RareGen members on the closing date of the Merger Transaction will be subject to a six-month lock-up as described under “The Merger Agreement — Agreements Entered Into in Connection with the Merger Agreement: Post-Closing Transfer Restrictions” on page 140. In the event that Holdback Shares are released or Net Sales Earnout Shares are issued, such shares will not have a lock-up restriction.

Following consummation of the Merger Transaction, approximately 43.9 million shares of HoldCo’s common stock are expected to be outstanding (including, for this purpose, the 616,666 Holdback Shares), of which approximately 4.9 million shares of HoldCo common stock, or approximately 11% of HoldCo’s outstanding shares following consummation of the Merger Transaction, are expected to be freely tradeable without restriction or further registration under the Securities Act of 1933, as amended, or the Securities Act, unless held by HoldCo’s “affiliates,” as that term is defined in Rule 144 under the Securities Act. Pursuant to the terms of the Merger Agreement, the HoldCo common stock issued to RareGen members on the closing date of the Merger Transaction will be subject to a six-month lock-up following the effective date of the Merger Transaction. Once the lock-up restriction on shares of HoldCo common stock issued to RareGen members expires, 5,550,000 shares of HoldCo common stock can be freely sold in the public market which could cause HoldCo’s stock price to decline.

We expect that the market price of HoldCo’s common stock may be volatile, and you may lose all or part of your investment.

The trading prices of the securities of pharmaceutical and biotechnology companies have been highly volatile. As such, the trading price of HoldCo’s common stock may be highly volatile and could be subject

TABLE OF CONTENTS

to wide fluctuations in response to various factors, some of which are beyond our control. The market price for HoldCo’s common stock may be influenced by many factors, including:

•

results of clinical trials of LIQ861, LIQ865 or any product candidate we may develop, or those of our competitors;

•

the success of Sandoz’s generic version of Remodulin® to which RareGen has commercial rights to pursuant to that certain Promotion Agreement between Sandoz and RareGen;

•

HoldCo’s cash resources;

•

the success of competitive products or technologies;

•

potential approvals of any product candidate we may develop for marketing by the FDA or equivalent foreign regulatory authorities or any failure to obtain such approvals;

•

HoldCo’s involvement in significant lawsuits, including stockholder or patent litigation, including inter partes review proceedings with originator companies or others which may hold patents, including United Therapeutics, and our current litigation with United Therapeutics in the U.S. District Court for the District of Delaware;

•

regulatory or legal developments in the United States and other countries;

•

the results of HoldCo’s efforts to commercialize any product candidate it may develop;

•

developments or disputes concerning patents or other proprietary rights;

•

the recruitment or departure of key personnel;

•

the level of expenses related to any of our product candidates or clinical development programs;

•

the results of HoldCo’s efforts to discover, develop, acquire or in-license additional product candidates or products;

•

actual or anticipated changes in estimates as to financial results, development timelines or recommendations by securities analysts;

•

variations in HoldCo’s financial results or those of companies that are perceived to be similar to HoldCo;

•

changes in the structure of healthcare payment systems;

•

market conditions in the pharmaceutical and biotechnology sectors and issuance of new or changed securities analysts’ reports or recommendations;

•

general economic, industry and market conditions; and

•

the other factors described in this “Risk Factors” section.

The stock market in general, and market prices for the securities of pharmaceutical companies like HoldCo in particular, have from time to time experienced volatility that often has been unrelated to the operating performance of the underlying companies. These broad market and industry fluctuations may adversely affect the market price of HoldCo’s common stock, regardless of its operating performance. Stock prices of many pharmaceutical companies have fluctuated in a manner unrelated or disproportionate to the operating performance of those companies. In several recent situations when the market price of a stock has been volatile, holders of that stock have instituted securities class action litigation against the company that issued the stock. If any of HoldCo’s stockholders were to bring a lawsuit against HoldCo, the defense and disposition of the lawsuit could be costly and divert the time and attention of HoldCo’s management and harm its operating results.

Future sales and issuances of equity securities, convertible securities or other securities could result in additional dilution of the percentage ownership of holders of HoldCo’s common stock.

HoldCo’s stockholders may experience dilution upon future equity issuances, including any other convertible debt or equity securities it may issue in the future, the exercise of stock options to purchase common stock granted to its employees, consultants and directors, including options to purchase common

TABLE OF CONTENTS

stock granted under its stock option and equity incentive plans, the issuance of common stock in settlement of previously issued awards under its stock option and equity incentive plans that may vest in the future or the issuance of common stock pursuant to its employee stock purchase plan.

We expect that significant additional capital will be needed in the future to continue HoldCo’s planned operations. To raise capital, HoldCo may sell equity securities, convertible securities or other securities in one or more transactions at prices and in a manner it determines from time to time. If HoldCo sells equity securities, convertible securities or other securities, current investors may be materially diluted by such subsequent sales. HoldCo may also need its stockholders to authorize the issuance of additional shares of common stock under its certificate of incorporation if it does not have sufficient authorized shares to raise such additional capital or issue future awards under its incentive plan. New investors could also gain rights, preferences and privileges senior to those of holders of HoldCo’s existing equity securities.

HoldCo’s principal stockholders and management will own a significant percentage of its stock and will be able to exercise significant influence over matters subject to stockholder approval.

HoldCo’s executive officers, directors and principal stockholders, together with their respective affiliates, will beneficially own approximately 33.2% of HoldCo’s common stock as of immediately following consummation of the Merger Transaction, of which 17.0% are expected to be beneficially owned by HoldCo’s executive officers and directors. Accordingly, HoldCo’s executive officers, directors and principal stockholders have significant influence in determining the composition of the HoldCo board of directors, and voting on all matters requiring stockholder approval, including mergers and other business combinations, and will have significant influence over HoldCo’s operations. This concentration of ownership could have the effect of delaying or preventing a change in control or otherwise discouraging a potential acquirer from attempting to obtain control of HoldCo that you may believe are in your best interests as one of HoldCo’s stockholders. This in turn could have a material adverse effect on HoldCo’s stock price and may prevent attempts by HoldCo’s stockholders to replace or remove the HoldCo board of directors or management.

As our Exchange Act reporting successor, HoldCo will continue to incur increased costs as a result of operating as a public company, and its management will be required to devote substantial time to new compliance initiatives and corporate governance practices.

As a public company, we are incurring significant legal, accounting and other expenses that we did not incur as a private company, including costs associated with public company reporting requirements, and HoldCo will incur these legal, accounting and other expenses following completion of the Merger Transaction. We have also incurred costs associated with recently adopted corporate governance requirements, including requirements of the SEC and the Nasdaq Stock Market LLC, or Nasdaq. These rules and regulations have increased our legal and financial compliance costs and made some activities more time-consuming and costly. These rules and regulations also make it more difficult and more expensive for us to obtain director and officer liability insurance and HoldCo may be required to accept reduced policy limits and coverage or incur substantially higher costs to obtain the same or similar coverage that we received as a private company. As a result, it may be more difficult for HoldCo to attract and retain qualified individuals to serve on its board of directors or as executive officers. We are currently evaluating and monitoring developments with respect to these rules, and we cannot predict or estimate the amount of additional costs we may incur or the timing of such costs.

When HoldCo ceases to be an “emerging growth company” and when its independent registered public accounting firm is required to undertake an assessment of its internal control over financial reporting, the cost of its compliance with Section 404 of the Sarbanes-Oxley Act will correspondingly increase. Moreover, if HoldCo is not able to comply with the requirements of Section 404 applicable to it in a timely manner, or if it or its independent registered public accounting firm identifies deficiencies in HoldCo’s internal control over financial reporting that are deemed to be material weaknesses, the market price of HoldCo’s common stock could decline and HoldCo could be subject to sanctions or investigations by the SEC or other regulatory authorities, which would require additional financial and management resources.

Anti-takeover provisions in HoldCo’s charter documents and under Delaware law could make an acquisition of HoldCo difficult, limit attempts by HoldCo’s stockholders to replace or remove its management and adversely affect HoldCo’s stock price.

Provisions of HoldCo’s certificate of incorporation and bylaws may delay or discourage transactions involving an actual or potential change in its control or change in its management, including transactions in

TABLE OF CONTENTS

which stockholders might otherwise receive a premium for their shares, or transactions that HoldCo stockholders might otherwise deem to be in their best interests. Therefore, these provisions could adversely affect the price of HoldCo stock. Among other things, the certificate of incorporation and bylaws:

•

permit the HoldCo board of directors to issue up to 10 million shares of preferred stock, with any rights, preferences and privileges as they may designate;

•

provide that the authorized number of directors may be changed only by resolution of HoldCo’s board of directors;

•

provide that all vacancies, including newly created directorships, may, except as otherwise required by law, be filled by the affirmative vote of a majority of directors then in office, even if less than a quorum;

•

require that any action to be taken by HoldCo’s stockholders must be effected at a duly called annual or special meeting of stockholders and may not be taken by written consent;

•

create a staggered board of directors such that all members of HoldCo’s board of directors are not elected at one time;

•

allow for the issuance of authorized but unissued shares of HoldCo’s capital stock without any further vote or action by its stockholders; and

•

establish advance notice requirements for nominations for election to the HoldCo board of directors or for proposing matters that can be acted upon at stockholders’ meetings.

In addition, because HoldCo is incorporated in Delaware, it is governed by the provisions of Section 203 of the Delaware General Corporation Law, or the DGCL, which generally prohibits a Delaware corporation from engaging in any of a broad range of business combinations with any stockholder owning in excess of 15% of our outstanding stock for a period of three years following the date on which the stockholder obtained such 15% equity interest in HoldCo.

The terms of HoldCo’s authorized preferred stock selected by its board of directors at any point could decrease the amount of earnings and assets available for distribution to holders of HoldCo common stock or adversely affect the rights and powers, including voting rights, of holders of HoldCo’s common stock without any further vote or action by the stockholders. As a result, the rights of holders of HoldCo common stock will be subject to, and may be adversely affected by, the rights of the holders of any preferred stock that may be issued by HoldCo in the future, which could have the effect of decreasing the market price of HoldCo common stock.

Any provision of HoldCo’s certificate of incorporation or bylaws or Delaware corporate law that has the effect of delaying or deterring a change in control could limit opportunities for its stockholders to receive a premium for their shares of common stock, and could also affect the price that investors are willing to pay for its common stock.

HoldCo’s certificate of incorporation designates the Court of Chancery of the State of Delaware as the sole and exclusive forum for certain types of actions and proceedings that may be initiated by its stockholders, which could limit its stockholders’ ability to obtain a favorable judicial forum for disputes with HoldCo or its directors, officers or other employees. Furthermore, HoldCo’s bylaws designates the federal district courts of the United States as the exclusive forum for the resolution of any complaint asserting a cause of action arising under the Securities Act which could be a less favorable judicial forum than state courts for stockholders with respect to disputes with HoldCo or its directors, officers or other employees.

HoldCo’s certificate of incorporation provides that, to the fullest extent permitted by law, the Court of Chancery of the State of Delaware will be the sole and exclusive forum for: (i) any derivative action or proceeding brought on HoldCo’s behalf; (ii) any action asserting a claim of breach of a fiduciary duty owed by any of HoldCo’s directors or officers to HoldCo or its stockholders; (iii) any action asserting a claim against HoldCo arising pursuant to any provision of the DGCL, HoldCo’s certificate of incorporation or bylaws; or (d) any action asserting a claim against HoldCo governed by the internal affairs doctrine. Furthermore, HoldCo’s bylaws designate the federal district courts of the United States as the exclusive forum for the resolution of any complaint asserting a cause of action arising under the Securities Act. Any

TABLE OF CONTENTS

person or entity purchasing or otherwise acquiring any interest in shares of HoldCo capital stock is deemed to have received notice of and consented to the foregoing provisions. These forum selection provisions may limit a stockholder’s ability to bring a claim in a judicial forum that it finds more favorable for disputes with HoldCo or its directors or officers, which may discourage such lawsuits against HoldCo and its directors or officers. Alternatively, if a court were to find this choice of forum provision inapplicable to, or unenforceable in respect of, one or more of the specified types of actions or proceedings, HoldCo may incur additional costs associated with resolving such matters in other jurisdictions, which could adversely affect HoldCo’s business, financial condition, prospects or results of operations.

Because HoldCo does not anticipate paying any cash dividends on its common stock in the foreseeable future, capital appreciation, if any, will be your sole source of gain.

We have never declared or paid cash dividends on our equity securities. As our successor, HoldCo currently intends to retain all of its future earnings, if any, to finance the growth and development of its business. In addition, the terms of our and HoldCo’s existing credit facility with Pacific Western Bank precludes HoldCo, and the terms of any future debt agreement may preclude HoldCo, from paying dividends. As a result, capital appreciation, if any, of HoldCo’s equity securities will likely be your sole source of gain for the foreseeable future.

Other Risk Factors

Our, RareGen’s and HoldCo’s businesses are and will be subject to the risks described above. In addition, our business is, and will continue to be, subject to the risks described in our Annual Reports on Form 10-K, as updated by subsequent Quarterly Reports on Form 10-Q, all of which are filed with the SEC and incorporated by reference into this proxy statement/prospectus.

Some of the information contained in this discussion and analysis or set forth elsewhere in this proxy statement/prospectus, including information with respect to RareGen’s plans and strategy for its business, includes forward-looking statements that involve risks and uncertainties. You should review the “Risk Factors” section of this proxy statement/prospectus for a discussion of important factors that could cause actual results to differ materially from the results described in or implied by the forward-looking statements contained in the following discussion and analysis.

Overview

RareGen, LLC, or RareGen, provides strategy, commercialization and investment support to companies developing therapeutics addressing rare diseases. On August 1, 2018, RareGen entered into its first partnership with Sandoz, Inc., or Sandoz, whereby the parties launched the first-to-file generic of treprostinil injection for the treatment of patients with pulmonary arterial hypertension, or PAH.

Promotion Agreement

RareGen entered into a Promotion Agreement with Sandoz on August 1, 2018, as amended on May 8, 2020, or the Promotion Agreement, pursuant to which Sandoz engaged RareGen on an exclusive basis to promote the appropriate use of Sandoz’s treprostinil, or the Product, for the treatment of PAH in the United States. Sandoz retains all rights in and to the Product. RareGen paid Sandoz an initial payment of $10 million on August 1, 2018 for the right to conduct the promotional activities as contemplated in the Promotion Agreement. Upon the successful quality release by Sandoz of 9,000 units of the Product, RareGen paid Sandoz $10 million in additional consideration for the right to conduct the promotional activities for the Product and receive a portion of the Net Profits (as defined below under “RareGen’s Business” beginning on page 69). The portion of Net Profits are allocated to RareGen as follows: (i) for that portion of aggregate Net Profits less than or equal to $500 million, RareGen shall receive between 50-80% of all such Net Profits; and (ii) for that portion of aggregate Net Profits greater than $500 million, RareGen shall receive 75% of all such Net Profits. For the year ended December 31, 2019, RareGen recognized revenues of $10.1 million for its share of Net Profits under the Promotion Agreement including contra revenue of approximately $3.3 million, related to the amortization of the upfront payments.

PBM Services Agreement

Pursuant to that certain services agreement with PBM Capital Group, dated August 7, 2018 and as amended on April 1, 2019, or the Services Agreement, PBM Capital Group is retained by RareGen to provide certain services including but limited to: (i) strategy and business development, (ii) operations management, (iii) contract negotiation and review, (iv) processing purchase orders issued by RareGen, (v) establishing, maintaining and administering benefit plans, (vi) maintaining financial books and records of RareGen and (vii) furnishing such other services as are incidental to the foregoing or usually or customarily furnished by a financial manager. RareGen pays a fee of $20,000 per month for the services provided by PBM Capital Group. As a condition precedent to closing the Merger Agreement, the Services Agreement will be terminated or, by agreement of our company, RareGen and PBM Capital Group, amended and restated, in either case as of the effective time of the Merger Transaction. For the year ended December 31, 2019, RareGen paid $0.3 million in management fees to PBM Capital Group under the Services Agreement. PBM Capital Group is a related party of RareGen. For more information, please see “Certain Relationships and Related Party Transactions of RareGen” beginning on page 165.

Recent Developments

Litigation Financing Agreement

On June 4, 2020, RareGen entered into a financing agreement with Henderson SPV, LLC to cover the prospective costs of the litigation with United Therapeutics Corporation, or United Therapeutics, and Smiths

TABLE OF CONTENTS

Medical ASD, Inc., or Smiths Medical, from the date of this agreement, in consideration for a share of the litigation proceeds. The share is a fixed percentage based on the litigation proceeds with various litigation proceed ranges. In the case where RareGen has no proceeds from the litigation, RareGen will have no obligation to Henderson SPV, LLC, or Henderson, for the litigation expenses that were previously financed. Henderson has not financed any costs of litigation as of the date of this proxy statement/prospectus.

Amendment to the Promotion Agreement with Sandoz, Inc.

On May 8, 2020, the Promotion Agreement with Sandoz was amended and significant provisions of the amendment are as follows:

•

Sandoz and RareGen will share any litigation proceeds in the current lawsuit or any future lawsuit they bring against United Therapeutics and Smiths Medical. The parties will also share equally in any losses incurred and approved expenses incurred. Note 7 includes a description of the circumstances regarding this litigation.

•

As described below, we and RareGen have entered into the Merger Agreement. Upon the closing of the Merger Transaction, RareGen will use good faith efforts to bring cartridges to market and make cartridges available for use with the Product, the initial term of the Promotion Agreement will be extended to eight years, and the formula for sharing net profits will be altered in exchange for Sandoz’s waiver of its right to terminate the Promotion Agreement for a change in control. Sandoz’s waiver of its right to terminate the Promotion Agreement for a change in control will be granted only if the Merger Transaction closes on or prior to September 30, 2020.

Merger Transaction

On June 29, 2020, we and RareGen entered into the Merger Agreement. The completion of the Merger Transaction is subject to the satisfaction of customary closing conditions, including approval by our stockholders and a registration statement on Form S-4, of which this proxy statement/prospectus forms a part, being declared effective by the SEC.

Upon satisfaction of the customary closing conditions, RareGen’s members will receive the following as consideration:

•

6,166,666 shares of our common stock; plus

•

the contingent right to receive up to 2,708,333 additional shares of our common stock if RareGen is able to meet certain net sales thresholds in 2021; plus

•

an amount in cash equal to the cash held by RareGen at closing, less $1.0 million, if any; plus

•

the contingent right to receive the amount of any payments received from Sandoz under the Promotion Agreement that are attributable to any periods prior to the closing date, if any.

Other Income (Expense)

Other income (expense), net consists of interest income on RareGen’s cash and cash equivalents.

Impact of COVID-19 on RareGen’s Business

RareGen has been actively monitoring the novel coronavirus, or COVID-19, situation and its impact globally. RareGen did not experience any material impact on its financial results for the quarter ended March 31, 2020. RareGen’s primary service relates to a life-sustaining, critical pharmaceutical for patients. As such, the demand for the service is directly impacted by these patients’ needs. The success of RareGen’s business is dependent on the distribution and supply chain managed by Novartis. Sandoz is a division of Novartis. RareGen continues to operate with the exception of enabling its employees, including field sales force, to work from home and abiding by travel restrictions issued by federal and local governments. As a result of these travel restrictions, sales representatives have been unable to physically visit hospitals and health care professionals, which may impact the near-term growth of RareGen’s business. Challenges may also be presented from a compliance monitoring standpoint,with more heavy reliance on remote and virtual oversight tools.

If the COVID-19 pandemic continues, RareGen may experience other disruptions that could severely impact its business, results of operations and prospects. The extent to which COVID-19 may impact RareGen’s business will depend on future developments, which are highly uncertain and cannot be predicted, such as the ultimate geographic spread of the disease, the duration of the outbreak, travel restrictions and social distancing in the United States and other countries, business closures or business disruptions and the effectiveness of actions taken in the United States and other countries to contain and treat the disease.

Net Service Revenue

Revenue for the quarter ended March 31, 2020 was $2.8 million, compared to $4.3 million for the quarter ended March 31, 2019. The decrease of $1.5 million was primarily the result of the first bulk order of the Product from a wholesaler occurring during the quarter ended March 31, 2019.

Operating Expenses

Litigation Expense

Litigation expenses for the quarter ended March 31, 2020 were $0.2 million, compared to $0.3 million for the quarter ended March 31, 2019. The decrease of $0.1 million was due to decreased legal fees and expenses related to the UTC/Smiths Medical litigation, in which RareGen is a co-plaintiff.

Payroll Expense

Payroll expenses for the quarter ended March 31, 2020 were $0.6 million, compared to $0.8 million for the quarter ended March 31, 2019. The decrease of $0.2 million was primarily due to a reduction in sales employees from natural attrition.

Contract Support, General and Administrative

Contract support, general and administrative expenses for the quarter ended March 31, 2020 were $0.2 million, compared to $0.4 million for the quarter ended March 31, 2019. The decrease of $0.2 million was primarily due to a reduction in marketing spend of $160,000 and a reduction in travel-related expenses of $50,000.

Management Fee

The management fee for each of the quarters ended March 31, 2020 and 2019 was $0.1 million, relating to amounts paid to PBM Capital Group to provide accounting, administrative, management and other services to RareGen.

Research and Development

Research and development expenses for the quarter ended March 31, 2020 were $26 thousand compared to $1 thousand for the quarter ended March 31, 2019. The increase of $25 thousand was primarily related to efforts undertaken by RareGen to develop a cartridge that can be used to administer the Product subcutaneously.

TABLE OF CONTENTS

equivalents of $3.6 million. RareGen expects its existing cash and cash equivalents and cash generated from operations will enable it to fund its operating expenses and capital expenditure requirements.

RareGen’s future capital requirements will depend on many factors, including:

•

RareGen’s ability to maintain the Promotion Agreement, on favorable terms, if at all;

•

the ability of RareGen and Sandoz to successfully sell the Product during the term of the Promotion Agreement;

•

the outcome, timing and cost of regulatory approvals for any medical devices used to administer the Product;

•

the cost and timing of hiring new employees to support RareGen’s continued growth; and

•

the costs of establishing and maintaining sales and marketing capabilities and related support.

RareGen expects to finance its future cash needs primarily through the receipt of its share of net profits under the Promotion Agreement and from reimbursement of UTC/Smiths Medical litigation expenses through the third-party litigation financing arrangement.

Off-Balance Sheet Arrangements

RareGen has not entered into any off-balance sheet arrangements.

Critical Accounting Policies

RareGen’s financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America, or GAAP, as determined by the Financial Accounting Standards Board, or FASB, Accounting Standards Codification, or ASC. The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. RareGen’s most critical accounting policies are summarized below. See note 2 to RareGen’s financial statements beginning on page F-1 of this proxy statement/prospectus for a description of RareGen’s other significant accounting policies.

On August 1, 2018, RareGen partnered with Sandoz in the Promotion Agreement to launch the first-to-file generic of treprostinil injection for the treatment of patients with PAH. Under the Promotion Agreement, RareGen will provide certain promotional and nonpromotional activities on an exclusive basis for the Product in the United States of America for the treatment of PAH, in exchange for a share of Sandoz’s net profits, as defined within the Promotion Agreement. In addition, RareGen paid Sandoz $20 million at the inception of the Promotion Agreement, in consideration for the right to conduct the promotional activities for the Product. In exchange for its services, RareGen is entitled to receive a portion of net profits based on specified profit levels associated with the Product.

RareGen determined that certain activities within the contract are within the scope of ASC 808, Collaborative Arrangements. The commercialization of the Product is a joint operating activity where RareGen will provide promotional and other activities for Sandoz’s Product and Sandoz will be responsible for items such as supply of the Product, distribution to customers, managing sales, returns, and regulatory matters. Both parties will be active participants, each carrying out its assigned responsibilities, and participating in the joint operating activity and will share in the risks and rewards of the commercialization through the profit-sharing arrangement.

In addition, RareGen determined that the services provided under the Promotion Agreement fall within the scope of Topic 606. While this is RareGen’s first income-generating contract, the promotional activities RareGen will perform are one of the services RareGen expects to provide as part of its ordinary activities, and it is receiving consideration for this service from Sandoz in the form of a share of future net profits. RareGen has one combined performance obligation under the Promotion Agreement, which is to perform promotional and non-promotional activities to encourage the appropriate use of the Product in

TABLE OF CONTENTS

accordance with the product labeling and applicable law. As such, and in accordance with ASU 2018-18: Clarifying the Interaction between Topic 808 and Topic 606, RareGen will account for the entire Promotion Agreement under Topic 606.

The share of net profits due to RareGen under the Promotion Agreement represents variable consideration as described in Topic 606 that is subject to a number of uncertainties, including the level of acceptance the Product achieves from health care providers that must prescribe the Product to their patients, or by payors such as insurers who must add the Product to their list of covered drugs, “gross to net” revenue adjustments, Sandoz’s costs, and competition from other products that have or may enter the market. As such, the recognition of revenue will be limited to the amount that is payable based on the net profit hurdles achieved to date. RareGen will receive payments representing its share of net profits on a quarterly basis based on net profits received by Sandoz to date during the term of the Promotion Agreement.

The $20 million paid by RareGen to Sandoz as consideration payable to the customer has been recorded as an asset that will be amortized on a straight-line basis into income as contra revenue over the initial term of five-year contract.

The Promotion Agreement has customary termination provisions for breach, bankruptcy of one of the parties, withdrawal of marketing approval, and safety concerns. Both parties have the right to terminate the Promotion Agreement before the end of the initial term in certain circumstances including if net profits targets are not reached after aggregate net profits received by the other party has reached a specified hurdle.

The Product was launched in March 2019. For the year ended December 31, 2019, RareGen recognized revenues for its share of net profits under the Promotion Agreement of approximately $10.1 million including contra revenue of approximately $3.3 million, related to the amortization of the upfront payments. For the three-month period ended March 31, 2020, RareGen recognized revenues for its share of net profits under the Promotion Agreement of approximately $2.8 million including contra revenue of approximately $1 million, related to the amortization of the upfront payments. For the three-month period ended March 31, 2019, RareGen recognized revenues for its share of net profits under the Promotion Agreement of approximately $4.4 million including contra revenue or approximately $333,000. At March 31, 2020, December 31, 2019 and December 31, 2018, the unamortized balances of the upfront payments made to Sandoz were approximately $15.7 million, $16.7 million and $20 million, respectively, which are included in Intangibles, net in RareGen’s balance sheet in the accompanying financial statements.

Recent Accounting Pronouncements

See note 2 to RareGen’s financial statements beginning on page F-1 of this proxy statement/prospectus for a description of recent accounting pronouncements applicable to RareGen’s financial statements.

Qualitative and Quantitative Disclosures about Market Risk

RareGen is affected by changes in the general level of U.S. interest rates, particularly because RareGen’s investments, including cash equivalents, are in the form of money market accounts.

Inflation generally affects RareGen by increasing its cost of labor. RareGen does not believe that inflation had a material effect on its business, financial condition or results of operations during the period from July 16, 2018 (date of inception) through December 31, 2018, the year ended December 31, 2019 or the three months ended March 31, 2020.

TABLE OF CONTENTS

RAREGEN’S BUSINESS

Overview

Pursuant to its Promotion Agreement with Sandoz, RareGen owns the exclusive rights to conduct any and all promotional and non-promotional activities to encourage the appropriate use of the first-to-file fully substitutable generic treprostinil injection for the treatment of patients with PAH in the United States, or the Product. To that end, RareGen has a small, targeted sales force focused on PAH which it employs to conduct such marketing activities. See below under “Promotion Agreement” on page 70 for more information.

Treprostinil, Remodulin® and the Generic Version of Remodulin®

Treprostinil/Remodulin® Generally

Treprostinil is a synthetic analog of prostacyclin, a vasoactive mediator essential to normal lung function that is deficient in patients with PAH. Treprostinil can be administered as a continuous infusion through the use of an infusion pump or continuous intravenous infusion through the use of a central venous catheter. PAH is a rare disease, with an estimated prevalence in the United States of approximately 30,000 patients. Of such patients, approximately 3,000 patients are on Remodulin®, which has annual sales of approximately $600 million. Remodulin® is treprostinil administered through subcutaneous or intravenous infusion and is marketed by United Therapeutics. Because parenteral agents are considered to offer the greatest efficacy, but also carry the most significant side effects related to infusion site pain, risk of infection, and significant limitations on quality of life, they are usually reserved for patients later in the course of the disease.

Treprostinil is currently sold mainly through specialty pharmacies, such as Accredo and CVS, and hospitals through traditional distributors. Treprostinil generally has a two-year shelf life, although Remodulin® has a four-year shelf life.

Remodulin® was approved by the FDA for subcutaneous and intravenous administration in 2002 and 2004, respectively, and has been sold commercially in the United States since 2002. United Therapeutics sells Remodulin® to specialty pharmaceutical distributors in the United States and to pharmaceutical distributors internationally. Remodulin® is indicated to treat patients with PAH, to diminish symptoms associated with exercise. Studies establishing effectiveness included patients with functional class II-IV (moderate to severe) symptoms. Outside of the United States, Remodulin® is marketed and sold for the treatment of PAH throughout most of Europe, and various countries throughout Asia, the Middle East and South America.

Remodulin® has many qualities that make it an appealing alternative to other parenteral therapies for the treatment of PAH. Remodulin® is stable at room temperature, so it does not need to be cooled during infusion and patients do not need to use cooling packs or refrigeration to keep it stable. Treprostinil is highly soluble under certain circumstances and highly potent in concentrated solutions. This allows therapeutic concentrations of Remodulin® to be delivered at very low flow rates via miniaturized infusion pumps for both subcutaneous and intravenous infusion. Remodulin® can be continuously infused for up to 48 hours before refilling the external infusion pump. This profile contrasts favorably with non-treprostinil based, continuously infused prostacyclin therapies that are presently available — Flolan®, Veletri® and generic epoprostenol. Flolan® and generic epoprostenol are not stable at room temperature (and therefore require refrigeration or the use of cooling packs), but Veletri® may be stable at room temperature depending on its concentration. Flolan®, generic epoprostenol, and Veletri® have shorter half-lives than Remodulin, requiring mixing prior to pump refills. None of these other parenteral products may be administered via subcutaneous infusion, and therefore may only be delivered intravenously.

Patients must use external pumps manufactured by third parties to deliver Remodulin®. Smiths Medical manufactures the pumps used by most patients in the United States to administer Remodulin®, including the CADD-MS® 3 (MS-3) pump used to deliver subcutaneous Remodulin®, and the CADD-Legacy® pump to deliver intravenous Remodulin®.

There are serious side effects associated with Remodulin®. For example, when infused subcutaneously, Remodulin® causes varying degrees of infusion site pain and reaction (redness and swelling) in most patients.

TABLE OF CONTENTS

Patients who cannot tolerate the infusion site pain related to the use of subcutaneous Remodulin® may instead use intravenous Remodulin®. Intravenous Remodulin® is delivered continuously through a surgically implanted central venous catheter, similar to Flolan®, Veletri® and generic epoprostenol. Patients who receive therapy through implanted venous catheters have a risk of developing blood stream infections and a serious systemic infection known as sepsis. Other common side effects associated with both subcutaneous and intravenous Remodulin® include headache, diarrhea, nausea, jaw pain, vasodilation and edema.

It is estimated that branded sales of Remodulin® recorded approximately $466 million in U.S. revenue in 2019 (and approximately $587 million in total, including approximately $121 million of non-U.S. sales), of which approximately 50% of branded Remodulin® sales derived from intravenous administration and 50% of branded Remodulin® sales derived from subcutaneous administration. The majority of sales made pursuant to the Promotion Agreement are made through specialty pharmacies. In consideration for RareGen conducting certain responsibilities associated with the commercialization of the Product, RareGen receives a portion of the net profits generated from the sales of the Product.

Sandoz

Sandoz, a Novartis division, is a global leader in generic pharmaceuticals and biosimilars. Sandoz’s purpose is to pioneer novel approaches to help people around the world access high-quality medicine. Sandoz’s broad portfolio of high-quality medicines, covering all major therapeutic areas, accounted for 2019 sales of $9.7 billion. Sandoz’s headquarters are in Holzkirchen, in Germany’s Greater Munich area.

Generic Version of Remodulin®

In 2011, Sandoz filed an ANDA with the FDA to market a generic version of treprostinil for parenteral administration. Sandoz claimed that United Therapeutics’ patents for Remodulin® were invalid, unenforceable and/or not infringed by its generic version of treprostinil. United Therapeutics then sued Sandoz for patent infringement and the parties settled that litigation in 2015. Pursuant to that settlement agreement, Sandoz was permitted to market its generic treprostinil alternative in June 2018 and United Therapeutics agreed to not interfere with Sandoz’s efforts to launch its generic product. In August 2018, Sandoz partnered with RareGen to jointly market and commercialize its generic version of treprostinil pursuant to a Promotion Agreement, as described below. The treprostinil is supplied in 20 mL multi-dose vials in four strengths — containing 20 mg, 50 mg, 100 mg, or 200 mg (1 mg/mL, 2.5 mg/mL, 5 mg/mL or 10 mg/mL) of treprostinil, respectively.

Sandoz launched the first-to-file fully substitutable generic treprostinil for parenteral administration in March 2019, followed by Teva Pharmaceuticals in October 2019. Par Pharmaceutical, Inc. launched a generic treprostinil for parenteral administration after receiving approval in September 2019, Dr. Reddy’s Laboratories Inc.’s received approval in May 2020 for generic treprostinil for parenteral administration, and Alembic Pharmaceuticals Ltd’s has settled with United Therapeutics in order to launch a generic treprostinil for parenteral administration, though it has not yet been approved to date. In March 2020, Teva obtained the rights to sell its generic product to CVS, which rights were previously held by RareGen and Sandoz. Currently, RareGen sells Sandoz’s generic product mainly through Accredo. The generic product launched by Sandoz and RareGen is a fully substitutable generic for Remodulin®, with the same active ingredient, same strength, same dosage forms and same inactive ingredient amounts as Remodulin®, and at the same service and support, but at a lower price. This product is currently used only for intravenous administration.

Pursuant to the UTC/Smiths Medical litigation, RareGen and Sandoz allege that Smiths Medical and United Therapeutics blocked access to cartridges necessary for administering the generic treprostinil through the CADD MS-3 pump manufactured by Smiths Medical for use in the administration of subcutaneous infusions of generic treprostinil.

Under the Promotion Agreement, Sandoz retains responsibility for: the specifications, manufacture and supply, distribution and future development of treprostinil; regulatory submission and interactions with the FDA pertaining to treprostinil, including maintaining all necessary regulatory approvals; reporting to the FDA or other regulatory authorities on matters relating to manufacturing, sale or promotion, such as any safety events involving treprostinil; internally reviewing and, as it determines appropriate, approving promotional materials developed by RareGen, and making submissions to the FDA’s Office of Prescription Drug Promotion; handling safety activities including adverse event reporting, and initiating and managing any recalls of treprostinil.

RareGen’s activities and obligations related to regulatory matters conducted under the Promotion Agreement include: promotional and non-promotional activities, including sales and marketing activities for treprostinil, and engagement of healthcare professionals for advisory boards; developing, with prior written approval from Sandoz, marketing and educational materials consistent with FDA approved labeling and applicable laws; notifying Sandoz of notices from governmental authorities about adverse event reports or regulatory inquiries related to the safety of treprostinil, product complaints or alleged defects, unsolicited requests for off-label medical information; providing certain data and information to Sandoz in order to fulfill its transparency and reporting obligations under the Physician Payment Sunshine Act; complying with applicable laws relevant to the activities conducted under the Promotion Agreement; establishing a compliance program and mechanism for disclosure of any violations of RareGen policies and procedures and submission of an annual report and certification to Sandoz of its compliance activities; and managing, with oversight and participation from Sandoz, negotiations and arrangements for managed care activities.

The Promotion Agreement, unless earlier terminated, initially extends until the eight (8) year anniversary of the first commercial sale of the Product by Sandoz, which occurred on or about March 25, 2019. The Promotion Agreement automatically renews for successive two-year terms unless earlier terminated.

RareGen paid Sandoz an initial payment of $10 million on August 1, 2018 and, upon the successful quality release by Sandoz of 9,000 units of the Product on August 3, 2018, RareGen paid Sandoz an additional $10 million as further consideration for the right to conduct the activities as contemplated in the Promotion Agreement and to receive a portion of the “Net Profits” (as defined below). The portion of Net Profits are allocated to RareGen as follows: (i) for that portion of aggregate Net Profits less than or equal to $500 million, RareGen shall receive between 50-80% of all such Net Profits; and (ii) for that portion of aggregate Net Profits greater than $500 million, RareGen shall receive 75% of all such Net Profits.

“Net Profits” are calculated based on net sales of the Product less (i) certain manufacturing costs incurred by Sandoz or its affiliates or any third party, if applicable, (ii) certain write-offs resulting from or relating to unsold and expired Products or components, (iii) costs associated with patient starter kits and (iv) certain other fees, charges and expenses charged by customers. RareGen also has the right to inspect and audit the records and books of account maintained by Sandoz, or any affiliate, as applicable, with respect to Net Profits and related factors.

RareGen also is required to use good faith efforts to bring to market 3ml cartridges for use in a Smiths Medical CADD-MS® 3 (MS-3) ambulatory infusion pump with treprostinil, or the Cartridges, and to market and make the Cartridges available for use with the Product. Upon termination of the Promotion Agreement, Sandoz may make and market the Cartridges pursuant to a license agreement as negotiated between RareGen and Sandoz in good faith.

TABLE OF CONTENTS

The Promotion Agreement required the formation of a joint steering committee, or JSC, which meets quarterly and consists of three representatives from each of RareGen and Sandoz. The purpose and responsibilities of the JSC include: (i) reviewing and approving updates or amendments to the “RareGen Activity Plan and Budget” (as defined in the Promotion Agreement); (ii) planning and implementating RareGen promotional activities; (iii) coordinating and implementing commercialization strategy; (iv) discussing the forecasting, procurement and manufacture of the Product and constituent parts; and (v) discussing status and terms of agreements with customers.

RareGen and Sandoz may terminate the Promotion Agreement for cause upon a number of customary events, such as a material breach of the Promotion Agreement that remains uncured, complete withdrawal of marketing approval of the Product or upon the filing or institution of bankruptcy, reorganization, liquidation or receivership proceedings with respect to the other party. Further, either party may terminate the Promotion Agreement upon written notice to the other party at any time after the initial eight (8) year term in the event Sandoz is then procuring 100% of its supply of Product from a single third party upon (a) expiration of the supply agreement with such third party and (b) Sandoz’s failure, after exercise of commercially reasonable efforts, to secure continued supply of the Product from such third party or other third parties within 12 months of the termination of such supply agreement. RareGen and Sandoz also each have a right to terminate the Promotion Agreement on not more than 90 days’ written notice in the event that Net Profits in the last calendar year are less than $5 million.

Sandoz may terminate the Promotion Agreement on not more than 90 days’ written notice after the conclusion of any full 12-month calendar year in the event that Net Profits in such calendar year are less than or equal to 10% of the net sales in such calendar year; provided, however, that Sandoz may not terminate the Promotion Agreement in such instance unless and until (i) aggregate amounts received by RareGen under the sharing of Net Profits have reached $32.5 million, or (ii) both (x) Net Profits or the profit margin were adversely affected in such calendar year by any temporary event or circumstance and (z) the JSC makes a determination that such profit margin deficiency is not likely to continue in the subsequent calendar year. Sandoz may also terminate the Promotion Agreement upon a change of control of RareGen; provided, however, that in connection with the first amendment to the Promotion Agreement, Sandoz waived this termination right provided that the Merger Transaction closes on or prior to September 30, 2020. In the event that the Merger Transaction does not close on or before September 30, 2020, RareGen will need to obtain an extension to Sandoz’s consent and waiver in order to satisfy the conditions to closing the Merger Transaction.

RareGen may terminate the Promotion Agreement on not more than 90 days’ written notice after the conclusion of any full 12-month calendar year in the event that RareGen’s share of the Net Profits in such calendar year are less than or equal to RareGen’s operating expenses relating to the Product for such calendar year; provided, however, that RareGen may not terminate the Promotion Agreement in such instance unless and until (i) aggregate amounts received by Sandoz under the share of Net Profits have reached $28.125 million, or (ii) both (x) Net Profits or its operating expenses relating to the Product were adversely affected in such calendar year by a temporary event or circumstance and (z) the JSC makes a determination that RareGen’s share of the Net Profits is not likely to continue to be less than its operating expenses relating to the Product in the subsequent calendar year.

Pursuant to the terms of the Promotion Agreement, Sandoz and RareGen also entered into a pharmacovigilance agreement on January 9, 2019, or the Pharmacovigilance Agreement. Under the Promotion Agreement, Sandoz is responsible for all pharmacovigilance activities regarding the Product while RareGen’s sole obligations related to pharmacovigilance is to notify Sandoz in the event that it receives safety information regarding the Product or information regarding any safety-related regulatory request or inquiry. The Pharmacovigilance Agreement establishes the procedures and guidelines that RareGen must follow when fulfilling its pharmacovigilance notification responsibilities.

PBM Services Agreement

TABLE OF CONTENTS

(v) establishing, maintaining and administering benefit plans, (vi) maintaining financial books and records of RareGen and (vii) furnishing such other services as are incidental to the foregoing or usually or customarily furnished by a financial manager. RareGen pays a fee of $20,000 per month for the services provided by PBM Capital Group. The Services Agreement automatically renews for successive one-year periods after the expiration of the initial term on August 7, 2019. However, the Services Agreement may be terminated by either party at any time, with or without cause with 60 days advance written notice. As a condition precedent to closing the Merger Agreement, the Services Agreement will be terminated or, by agreement of us, RareGen and PBM Capital Group, amended and restated, in either case as of the effective time of the Merger Transaction.

Joint Development Agreement

Pursuant to a Joint Development Agreement, dated May 6, 2019, by and between RareGen and Carelife USA Inc., or Carelife, RareGen has engaged Carelife to perform certain development and manufacturing services, and to furnish finished cartridges when ready for commercial sale. Currently, RareGen is working with Carelife to develop a medication cartridge for use with CADD-MS® 3 (MS-3) ambulatory infusion pumps. Pursuant to the Joint Development Agreement, Carelife or an affiliate of Carelife will manufacture the medication cartridge for use with CADD-MS® 3 ambulatory infusion pumps that is currently under development by RareGen and Carelife. Such manufacturer will then sell cartridges to a distributor who will import the cartridges into the United States and sell them to specialty pharmacies and other customers. It is contemplated that RareGen will only receive a commission or fee on sales of the cartridges to the specialty pharmacies and other customers. The amount of RareGen’s fee is to be negotiated. All other amounts received with respect to the manufacture and sale of such cartridges will be paid to the manufacturer, distributor and/or other third parties.

Each party is responsible for providing the necessary systems, personnel and materials to perform the tasks assigned to it according to the terms of the Joint Development Agreement. Additionally, RareGen is responsible for (i) costs and expenses related to the production of product molds, and (ii) third party costs and expenses relating to testing of any products manufactured by Carelife in accordance with the Joint Development Agreement. RareGen retains all intellectual property and technology created pursuant to the Joint Development Agreement.

The initial term of the Joint Development Agreement expires on May 6, 2027, and RareGen may terminate at any time upon 30 days’ prior written notice.

Marketing, Sales and Support

RareGen has a PAH-seasoned small, targeted sales force that provides strategy, investment and commercialization for the Product. RareGen also engages a consultant for certain marketing services. RareGen closely coordinates with specialty pharmacies to maximize the patient experience and adoption. Specialty pharmacies own the infusion pumps and supply them to patients as needed, along with the drug and other ancillary equipment required for continuous infusion.

The majority of sales made pursuant to the Promotion Agreement are made through specialty pharmacies, due to its investments in health care professionals, or HCPs, and patient experience and support. Currently, approximately 95% of quantities are sold through specialty pharmacies.

Following the closing of the Merger Transaction, RareGen, as a subsidiary of HoldCo, will continue to carry out its responsibilities under the Promotion Agreement, including sales and marketing. RareGen

and Sandoz are jointly responsible for commercial strategy and payer strategy. Sandoz will continue to hold the ANDA, manage the supply chain, recognize and report revenue, and manage contracts with payers.

[MISSING IMAGE: tm2025040d1-tbl_raregen4clr.jpg]

Research, Development and Engineering

RareGen continues to pursue potential collaborations and partnerships with third parties to develop ambulatory infusion pumps that would be suitable for administration of generic treprostinil to patents.

Intellectual Property

RareGen does not currently hold any patent, published patent applications or U.S. copyright registrations and currently holds one registered trademark, “RAREGEN”. Much of RareGen’s intellectual property consists of know-how and goodwill which is valid and enforceable only insofar as it qualifies as trade secrets under applicable law.

Additionally, pursuant to the Promotion Agreement, RareGen has the non-exclusive right to use Sandoz’s trademarks and copyrights on (i) labels and other written, printed or graphic matter on (x) any container or wrapper utilized with the Product or (z) any written material accompanying the Product and (ii) any other Product materials provided by or on behalf of Sandoz for use in connection with RareGen’s promotional activities. Any improvement, enhancement or modification made, discovered, conceived, reduced to practice or generated by RareGen to any of RareGen’s know-how (as defined in the Promotion Agreement) in performing its promotional activities shall vest in RareGen if it is not derived from Sandoz’s confidential information.

Government Regulation

RareGen does not itself hold any drug approvals from the FDA or any similar governmental authority, nor does it bill government or commercial payors for any pharmaceutical products. Given, however, that RareGen provides services to the pharmaceutical industry that include sales and marketing and certain educational communication services, FDA laws and other federal laws governing healthcare are relevant to its business and the related risks. Additionally, certain states have implemented laws applicable to pharmaceutical companies whereby they must also comply with, among other things, transparency requirements regarding sales and marketing activities, and prohibitions or restrictions on financial arrangements or activities with healthcare professionals.

At the federal level, FDA law prohibits “misbranding” of drugs and establishes related rules and policies on promotional and non-promotional (educational, scientific) communications, and as such, interactions with or communications directed to healthcare professionals, or HCPs, or prospective customers, or patients or patient- or disease-advocates or advocacy groups, are subject to heightened scrutiny by the FDA. Relative to non-promotional communications, for example, there are specific FDA accommodations for non-promotional, truthful and non-misleading sharing of information regarding products in development and off-label uses including dissemination of peer-reviewed reprints that contain off-label information, support of independent continuing medical education, or CME, that may include discussion of off-label information, and healthcare economic discussions with payors. These non-promotional communications, while permitted by the FDA, are subject to a number of limitations as well as industry compliance best

TABLE OF CONTENTS

practices. Additionally, although the FDA would typically look primarily to the ANDA holder for responsibility for the compliance of its products including as related to outsourced services that it obtains from third parties, the Food, Drug, and Cosmetic Act is broad in scope such that if any third party were found to have “caused” misbranding the FDA could theoretically take enforcement action against that entity, even if not explicitly in a directly regulated role.

Compliance with these FDA laws also has relevance to healthcare fraud and abuse laws such as (i) the False Claims Act, or the FCA, as off-label promotion can be used as a basis the government to take action under the FCA, and (ii) the Anti-Kickback Statute, or AKS, as healthcare professionals who receive payment for services, such as advisory board services, who are not clearly documented as providing bona fide services for which only fair market value has been paid can raise AKS-related concerns.

The AKS prohibits, among other things, persons and entities from knowingly and willfully soliciting, receiving, offering or paying remuneration, directly or indirectly, overtly or covertly, in case or in kind, to induce or reward, or in return for, or either the referral of an individual for, or the purchase, lease or order or recommendation of an item or service reimbursable, in whole or in part, under a federal healthcare program, such as the Medicare and Medicaid programs. This statute has been interpreted broadly to apply to, among other things, arrangements between pharmaceutical manufacturers on the one hand and prescribers, purchasers and formulary managers on the other hand. The term “remuneration” expressly includes kickbacks, bribes or rebates and also has been broadly interpreted to include anything of value. There are a number of statutory exceptions and regulatory safe harbors protecting certain common activities from prosecution or other regulatory sanctions; however, the exceptions and safe harbors are drawn narrowly, and practices that do not fit squarely within an exception or safe harbor may be subject to scrutiny. The failure to meet all of the requirements of a particular applicable statutory exception or regulatory safe harbor does not make the conduct per se illegal under the federal Anti-Kickback Statute. Instead, the legality of the arrangement will be evaluated on a case-by-case basis based on a cumulative review of all of its facts and circumstances. Our sales and marketing practices may not meet all of the criteria for safe harbor protection from AKS liability in all cases. A person or entity does not need to have actual knowledge of the AKS or specific intent to violate it to have committed a violation. In addition, Patient Protection and Affordable Care Act of 2010, as amended, or the ACA, codified case law that a claim including items or services resulting from a violation of the AKS constitutes a false or fraudulent claim for purposes of the FCA.

The federal FCA prohibits individuals or entities from, among other things, knowingly presenting or causing the presentation of a claims payment to, or approval by, the federal government that are false, fictitious or fraudulent, or knowingly making, using or causing to be made or used, a false record or statement material to a false or fraudulent claim to avoid, decrease or conceal an obligation to pay money to the federal government. As a result of a modification made by the Fraud Enforcement and Recovery Act of 2009, a claim includes “any request or demand” for money or property presented to the federal government. Although we do not submit claims directly to payors, manufacturers can be held liable under these laws if they are deemed to “cause” the submission of false or fraudulent claims by, for example, providing inaccurate billing or coding information to customers, promoting a product for unapproved uses (also known as “off-label promotion”), marketing products of sub-standard quality, or, as noted above, paying a kickback that results in a claim for items or services in violation of the AKS. The FCA also permits a private individual acting as a “whistleblower” to bring actions on behalf of the federal government alleging violations of the FCA and to share in any monetary recovery. In addition, certain marketing practices, including off-label promotion, may also implicate the FCA. Although the FCA is a civil statute, conduct that results in a FCA violation may also implicate various federal criminal statutes.

Employees

As of March 31, 2020, RareGen employed nine employees on a full-time basis, consisting of seven active sales employees, RareGen’s Chief Executive Officer and RareGen’s Chief Operating Officer. In addition, RareGen contracts with consultants for services. RareGen believes that its future success will depend in large part on its ability to recruit and retain qualified employees, particularly highly skilled sales representatives. At times RareGen has experienced difficulty in attracting new personnel, and RareGen may not be successful in retaining or recruiting sufficient key personnel in the future. None of RareGen’s employees is represented by a labor union, and RareGen has never experienced a work stoppage, slowdown or strike. RareGen considers its relationship with its employees to be good.

Properties

RareGen’s corporate headquarters are located in Durham, North Carolina, and consist of approximately 1,350 square feet of space under a lease that expires on October 31, 2020. The permitted use of this location is general office. RareGen believes that its facility is adequate for its current needs.

Legal Proceedings and Related Agreements

On April 16, 2019, Sandoz and RareGen filed a complaint against United Therapeutics and Smiths Medical in the District Court of New Jersey (Case No. No. 3:19-cv-10170), or the UTC/Smiths Medical litigation, alleging that United Therapeutics and Smiths Medical violated the Sherman Antitrust Act of 1890, state law antitrust statutes and unfair competition statutes by engaging in anticompetitive acts regarding the drug treprostinil for the treatment of PAH. On March 20, 2020, Sandoz and RareGen filed a first amended complaint adding a claim that United Therapeutics breached a settlement agreement that was entered into in 2015, in which United Therapeutics agreed to not interfere with Sandoz’s efforts to launch its generic treprostinil, by taking calculated steps to restrict and interfere with the launch of Sandoz’s competing generic product. United Therapeutics developed treprostinil under the brand name Remodulin® and Smiths Medical manufactured a pump and cartridges that are used to inject treprostinil into patients continuously throughout the day. Sandoz and RareGen allege that United Therapeutics and Smiths Medical entered into anticompetitive agreements (i) whereby Smiths Medical placed restrictions on the cartridges such that they can only be used with United Therapeutics’ branded Remodulin® product and (ii) requiring Smiths Medical to enter into agreements with specialty pharmacies to sell the cartridges only for use with Remodulin®.

On January 29, 2020, the court denied RareGen’s and Sandoz’s motion for a preliminary injunction and United Therapeutics’ and Smiths Medicals’ motion to dismiss. The litigation is proceeding through the discovery process.

HoldCo or its subsidiaries post-closing will not be entitled to any proceeds resulting from, or bear any financial or other liability for, the UTC/Smiths Medical litigation.

RareGen may become subject to additional legal proceedings and claims arising in connection with the normal course of its business. In the opinion of RareGen’s management, except as disclosed herein, there are currently no claims that would have a material adverse effect on RareGen’s financial position, results of operations or cash flows.

Financing Agreement

On June 4, 2020, RareGen entered into a financing agreement with Henderson SPV, LLC, or Henderson, to cover prospective costs of the litigation with United Therapeutics and Smiths Medical, from the date of this agreement, in consideration for a share of the litigation proceeds. In the event that RareGen has no proceeds from the litigation, Henderson will have no right to recover any litigation expenses that were previously financed. Henderson has not financed any costs of litigation as of the date of this proxy statement/prospectus.

UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL STATEMENTS OF HOLDCO

On June 29, 2020, we and RareGen entered into the Merger Agreement. Under the terms of the Merger Agreement, Liquidia Merger Sub, a wholly owned subsidiary of HoldCo, will merge with and into our company and our stockholders will receive one share of HoldCo common stock in exchange for each share of our common stock at the effective time of the Merger Transaction. In addition, RareGen Merger Sub, a wholly owned subsidiary of Liquidia Corporation, will merge with and into RareGen under the Merger Transaction. Upon consummation of the Merger Transaction, the separate corporate existences of Liquidia Merger Sub and RareGen Merger Sub will thereupon cease and our company and RareGen will continue as wholly owned subsidiaries of Liquidia Corporation.

The following unaudited pro forma condensed combined financial statements give effect to the Merger Transaction. The Unaudited Pro Forma Condensed Combined Balance Sheet is presented as if the Merger Transaction had occurred on March 31, 2020. The Unaudited Pro Forma Condensed Combined Statements of Income for the three months ended March 31, 2020 and for the year ended December 31, 2019 are presented as if the Merger Transaction had occurred on January 1, 2019, the beginning of the earliest period presented. The unaudited pro forma financial information is based on the historical consolidated financial statements of our company and RareGen, and the assumptions and adjustments set forth in the accompanying explanatory notes. This unaudited pro forma condensed combined financial information was prepared using the acquisition method of accounting where we are considered the acquirer of RareGen for accounting purposes. See “Note 2 — Basis of Presentation” below on page 81.

The unaudited pro forma condensed combined financial information for the Merger Transaction has been developed from and should be read in conjunction with our unaudited interim financial statements contained in our Quarterly Report on Form 10-Q for the three months ended March 31, 2020 filed with the SEC on May 11, 2020 and our audited financial statements contained in our Annual Report on Form 10-K for the year ended December 31, 2019 filed with the SEC on March 16, 2020, which are each incorporated by reference into this proxy statement/prospectus. The acquisition of RareGen will be accounted for as a business combination and will reflect the application of acquisition accounting in accordance with Accounting Standards Codification (ASC) 805, Business Combinations. For purposes of developing the Unaudited Pro Forma Condensed Combined Balance Sheet as of March 31, 2020, the acquired RareGen assets, including identifiable intangible assets and liabilities assumed, have been recorded at their estimated fair values with the excess purchase price assigned to goodwill. The pro forma adjustments are based on preliminary estimates of the fair values of assets acquired and liabilities assumed and information available as of the date of this proxy statement/prospectus. Certain valuations and assessments, including valuations of the fixed assets, contingent consideration, other intangible assets as well as the assessment of the tax positions and rates of the combined business, are in process and will not be completed until subsequent to the close of the proposed acquisition. The estimated fair values assigned in this unaudited pro forma financial information are preliminary and represent our current best estimate of fair value and are subject to revision.

At the effective time of the Merger Transaction, an aggregate of 6,166,666 shares of HoldCo common stock, including 616,666 shares of HoldCo common stock which will be withheld from RareGen members to secure the indemnification obligations of RareGen members, will be issued to RareGen members in exchange for 10,000 RareGen common units, representing all of the issued and outstanding RareGen equity. Additionally, RareGen members shall be entitled to a pro rata portion of any RareGen cash at closing in excess of $1 million. RareGen members are also entitled to receive a pro rata portion of up to an additional 2,708,333 shares of HoldCo common stock in the aggregate in 2022, based on the amount of 2021 net sales of the generic treprostinil product owned by Sandoz, which RareGen markets pursuant to the Promotion Agreement, which are referred to herein as Net Sales Earnout Shares. Please see Note 3 below for further detail on consideration paid to RareGen members. The fair value of the purchase consideration, or the purchase price, in the unaudited pro forma condensed combined financial information is estimated to be approximately $37.4 million. The purchase consideration consists of the 6,166,666 shares of HoldCo common stock based on a per share price of $5.38, which represents the closing price of our common stock on July 27, 2020, and the estimated fair value of the contingent consideration liability of $4.3 million.

NOTES TO THE UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL STATEMENTS

Description of Transaction

Consideration paid to RareGen

RareGen members will receive an aggregate of 6,166,666 shares of HoldCo common stock, including 616,666 shares of HoldCo common stock which will be withheld from RareGen members to secure the indemnification obligations of RareGen members, in exchange for 100% of the membership interests in RareGen. RareGen members are also entitled to receive between 1,458,333 shares of HoldCo common stock, in the event that 2021 net sales under the Promotion Agreement equals $32.9 million, and 2,708,333 shares of HoldCo common stock in the event that 2021 net sales under the Promotion Agreement equals $61.1 million. Additionally, RareGen members shall be entitled to a pro rata portion of any RareGen cash at closing in excess of $1 million, which is referred to in the Merger Agreement as the Minimum Cash Amount. This number of shares of HoldCo common stock to be exchanged in the Merger Transaction will not be adjusted for changes in the market price or number of shares outstanding of either our common stock between the date of signing the Merger Agreement and completion of the Merger Transaction or, for purposes of the Net Sales Earnout Shares, the HoldCo common stock between the date of completion of the Merger Transaction and the date of determination whether 2021 net sales are at least $32.9 million.

Basis of Presentation

The accompanying unaudited pro forma condensed combined financial statements give effect to the Merger Transaction in which RareGen will merge with and into our company. The unaudited pro forma condensed combined financial information is based on the historical consolidated financial statements of our company and RareGen, and the assumptions and adjustments set forth in these notes. The unaudited pro forma condensed combined financial information is provided for informational purposes only and is based on available information and assumptions that we believe are reasonable. It does not purport to represent what the actual consolidated results of operations or the consolidated financial position of HoldCo would have been if the Merger Transaction occurred on the dates indicated, nor is it necessarily indicative of future consolidated results of operations or consolidated financial position. The actual financial position and results of operations will differ, perhaps significantly, from the pro forma amounts reflected herein due to a variety of factors, including access to additional information, changes in value not currently identified and changes in operating results following the date of the pro forma financial information.

Merger-related pro forma adjustments are included only to the extent they are adjustments that reflect the accounting for the transaction in accordance with U.S. GAAP. The accompanying unaudited pro forma condensed combined financial information is presented for informational purposes only and is based on available information and assumptions that we believe are reasonable.

The Merger Transaction will be accounted for using the acquisition method of accounting with our company considered the accounting and legal acquirer. The unaudited pro forma condensed combined financial information reflects the preliminary assessment of fair values and useful lives assigned to the assets acquired and liabilities assumed. Fair value estimates were determined based on preliminary discussions between us and RareGen and through due diligence efforts. The detailed valuation studies necessary to arrive at the required estimates of the fair values for the RareGen assets acquired and liabilities assumed have not been completed. Significant assets and liabilities that are subject to preparation of valuation studies to determine appropriate fair value adjustments include intangible assets, deferred income tax liability and accrued costs. Changes to the fair values of these assets and liabilities will also result in changes to goodwill recorded from the acquisition, which could be material.

Preliminary Purchase Consideration

The fair value of the purchase consideration, or the purchase price, in the unaudited pro forma condensed combined financial information is estimated to be approximately $37.4 million. The purchase consideration consists of the 6,166,666 shares of HoldCo common stock based on a per share price of $5.38,

TABLE OF CONTENTS

which represents the closing price of our common stock on July 27, 2020, and the estimated fair value of the contingent consideration liability of $4.3 million.

Given that the estimated purchase price is variable depending upon the valuation of our company and our common stock, management performed a sensitivity analysis over the change in purchase consideration, exclusive of contingent consideration, based on +/ — 10% volatility in our common stock valuation. An increase or decrease in the valuation of our common stock by 10% would increase or decrease the purchase consideration by approximately $3.3 million with an offsetting adjustment to Goodwill in the unaudited condensed consolidated pro forma balance sheet.

The total estimated purchase price and allocated purchase price is summarized as follows:

Number of shares of the combined company to be owned by RareGen’s members		6,166,666
Multiplied by the fair value per share of Liquidia Technologies common stock	$	5.38
Total estimated stock value	$	33,176,663
Contingent consideration liability	$	4,265,000
Total estimated purchase price		37,441,663

For purposes of this pro forma analysis, the above estimated purchase price has been allocated as follows based on a preliminary estimate of the fair value of assets and liabilities to be acquired as of March 31, 2020:

Cash	$	1,000,000
Property and equipment		80,605
Prepaid and other current assets		43,816
Intangible asset		14,547,000
Other assets		13,022,464
Goodwill		11,437,002
Less current liabilities		(364,224)
Less deferred tax liability		(2,325,000)
Total estimated purchase price	$	37,441,663

Pro Forma Adjustments

In May 2020, the SEC adopted Release No.33-10786 “Amendments to Financial Disclosures about Acquired and Disposed Businesses”, or the Final Rule. The Final Rule is effective on January 1, 2021, however, voluntary early adoption is permitted. We have elected to early adopt the provisions of the Final Rule, and the unaudited pro forma condensed combined financial information herein is presented in accordance therewith.

Adjustments included in the column under the heading “Transaction Accounting Adjustments” are solely based on information contained within the Merger Agreement. Transaction Accounting Adjustments are required adjustments that reflect only the application of required accounting to the transaction linking the effects of the acquisition of RareGen to our historical financial statements.

Given our history of net losses and valuation allowance, management assumed a statutory tax rate of 0%. Therefore the pro forma adjustments to the statement of operations resulted in no income tax adjustment to the pro forma financials.

Pro forma adjustments are necessary to reflect the acquisition consideration exchanged and to adjust amounts related to the tangible assets and liabilities of RareGen to reflect the preliminary estimate of their fair values, and to reflect the impact on the balance sheets and statements of operations of the Merger Transaction as if the companies had been combined during the periods presented therein. The pro forma adjustments included in the unaudited pro forma condensed combined financial statements are as follows:

TABLE OF CONTENTS

To adjust cash received from RareGen as RareGen members are entitled to a pro rata portion of all cash in excess of $1.0 million at the closing per the terms of the Merger Agreement.

To adjust the accounts receivable from the Promotion Agreement generated prior to the closing of the Merger Agreement. Any payments owed from Sandoz prior to the closing of the Merger Transaction will not be part of the assets acquired.

To record the fair value of the intangible asset and other asset acquired and the residual goodwill from the Merger Transaction. Goodwill, representing the excess of the purchase price over the fair value of the assets to be acquired, is $11,437,002. This allocation is based on preliminary estimates. The final allocation may differ materially from this estimate as changes to the initial valuation of assets and liabilities will be allocated to goodwill.

To reclassify Due to related party balance to Accounts payable if the Merger Transaction were in effect as of the balance sheet date.

To reflect the issuance of HoldCo common stock to existing members of RareGen and the elimination of RareGen’s historical members’ equity balance, including accumulated earnings.

To reflect estimated transaction expenses of $4,000,000 in the unaudited pro forma condensed combined balance sheet and record these expenses in the earliest period presented. These transaction costs are one-time non-recurring expenses directly associated with the Merger Transaction.

To record a deferred tax liability for the difference between the future tax and book amortization of the acquired intangible and other assets utilizing the blended federal and state statutory income tax rate of approximately 23% for the three months ended March 31, 2020.

To record the preliminary estimated fair value of the contingent consideration payable to the RareGen members upon the achievement of certain net sales in 2021. The preliminary estimated fair value of the contingent consideration was valued using a Monte Carlo simulation technique. Before acquisition, this liability will be remeasured to its fair value at the end of each reporting period and subsequent changes in the fair value after acquisition will be recognized in the Company’s statement of operations as a component of operating income or expenses.

To record the amortization expense applicable to the related period for the intangible asset acquired as part of the business combination. The newly acquired intangible asset has been amortized using an estimated useful life of eight years. The intangible asset is being amortized to cost of revenue based on the expected timing of yearly net revenues versus the expected total net revenues from the Promotion Agreement as this represents management’s best estimate of the pattern of utilization for the intangible asset. We are still in the process of evaluating the fair value of the intangible asset. Any resulting change in the fair value would have a direct impact to amortization expense.

PROPOSAL 1 — THE MERGER TRANSACTION

This section describes material aspects of the proposed Merger Transaction, including the Merger Agreement. While we and RareGen believe that this description covers the material terms of the Merger Transaction and the Merger Agreement, this description may not contain all of the information that is important to you. You should read carefully this entire document and the other documents to which we and RareGen refer, including the Merger Agreement attached to this proxy statement/prospectus as Annex A, for a more complete understanding of the Merger Transaction and the Merger Agreement. The following description is subject to, and is qualified in its entirety by reference to, the Merger Agreement.

Background of the Merger Transaction

As part of the ongoing evaluation of our business, members of our senior management and our board of directors have periodically reviewed and assessed our financial performance and operations, financial condition and industry and regulatory developments in the context of our mid to long-term strategic goals and plans, including the consideration of potential opportunities to enhance stockholder value through licensing transactions, acquisitions, business combinations and other financial and strategic alternatives.

Beginning in the third quarter of 2019, we conducted informal discussions, including in-person meetings, with several third parties including RareGen and PBM Capital Finance, or PBM, regarding a potential strategic partnership or other commercial relationship. On December 11, 2019, we signed a Confidentiality Agreement with RareGen and we made confidential information available to each other about our respective businesses. The discussions were preliminary in nature, and discussions between the parties did not progress due to significant differences in expectations regarding potential transaction terms. We also signed confidentiality agreements with several other third parties, but discussions did not progress past preliminary stages.

On March 3, 2020, Paul B. Manning,the manager and sole beneficial owner of PBM, a holder of 70.65% of RareGen’s equity, called Neal Fowler, our Chief Executive Officer, and indicated that RareGen and PBM were interested in re-engaging with us regarding a potential strategic transaction. On March 6, 2020, members of RareGen management, representatives of PBM, members of our management, a representative of our board of directors and representatives of a private investment manager that we refer to as “Party X” met in person in at our executive offices in Raleigh, North Carolina. At the meeting, our representatives and representatives of RareGen discussed our respective businesses and the financial and strategic benefits of combining the two companies. Mr. Manning proposed a potential transaction, involving our acquisition of RareGen and a simultaneous investment in us by Party X and other investors to be led by Party X, which we refer to as the potential PIPE financing. The parties also discussed the relationship between RareGen and Sandoz under the Promotion Agreement, and the consent that would be required from Sandoz if RareGen were to be acquired by us. The parties also discussed RareGen’s pending litigation with United Therapeutics and Smiths Medical, and how the litigation would be treated in any transaction between us and RareGen. Mr. Manning indicated that following the meeting, RareGen would send a term sheet setting forth the terms of a proposed business combination transaction and a simultaneous PIPE financing. The parties agreed to continue discussions to determine whether a mutually beneficial transaction might be achievable.

On March 7, 2020, we received a non-binding term sheet from RareGen on behalf of RareGen and Party X, which set out the proposed terms for the acquisition of RareGen and the proposed simultaneous PIPE financing. The term sheet contemplated our acquisition of RareGen in a stock-for-stock merger, in which members of RareGen would receive aggregate merger consideration of $50 million in the form of our common stock. The term sheet also contemplated a simultaneous PIPE financing of up to $60 million led by Party X. The term sheet also included a provision which carved-out of the transaction RareGen’s pending litigation with United Therapeutics and Smiths Medical, with RareGen members retaining liability for all expenses and liabilities related to the litigation, and RareGen members receiving all proceeds from the litigation or any settlement.

On March 9, 2020, our board of directors met to discuss the terms set forth in the March 7th term sheet. At the meeting, the board of directors formed a transaction committee (the “Transaction Committee”) consisting of Messrs. Fowler and Kirsch and Drs. Bloch, Horobin and Rudnick to facilitate the board of

TABLE OF CONTENTS

director’s consideration of a potential transaction with RareGen, and authorized our management to engage third party advisors to assist in our evaluation of a potential transaction. Our board of directors discussed the benefits of a combination with RareGen, including the potential to leverage RareGen’s existing sales force, infrastructure and marketing relationships for our product candidates, and the increased financial strength resulting from access to RareGen’s cash flow generated by sales of a generic version of Remodulin. The board authorized our management to engage in discussions with RareGen, PBM and Party X relating to the transactions, and to provide confidential information to RareGen, PBM and Party X. In accordance with the authorization of our board of directors, we engaged DLA Piper as our legal advisor and Jefferies LLC as our financial advisor in connection with the proposed transaction. We also engaged Triangle Insights Group, LLC to assist our management with their due diligence review of RareGen.

Between March 9, 2020 and April 9, 2020, we had several calls with DLA Piper, RareGen, PBM and Party X to discuss the transactions set forth in the March 7th term sheet and exchanged several drafts of the term sheet reflecting the matters discussed by the parties. The parties discussed the proposed merger consideration, and whether a portion of the merger consideration should be structured as an earnout, with additional shares of our common stock issued to RareGen members if RareGen achieved certain revenue targets. The parties also discussed governance matters, including the composition of the combined company board of directors and representation on the combined company board of directors by certain RareGen members and a representative of Party X. The parties also continued to discuss other provisions of the term sheet, including indemnification matters and conditions to closing, which included the consent of Sandoz to the proposed transaction. Also during this time, our representatives and representatives RareGen and our respective advisors engaged in a due diligence review of each other, which included a review of legal, commercial and regulatory matters, and forecasts through 2024 prepared by RareGen management and provided to us by RareGen.

On April 9, 2020, the Transaction Committee met, with our management and representatives of DLA Piper and Jefferies in attendance. Representatives of DLA Piper and Jefferies updated the Transaction Committee on the status of negotiations with respect to the proposed transactions, and presented a summary of the provisions included in the most recent draft of the term sheet being discussed by the parties. Representatives of DLA Piper and Jefferies reviewed for the Transaction Committee the proposed merger consideration, including the number of shares of our common stock to be issued to RareGen members and our management’s proposal to structure a portion of the consideration as an earnout payment, with additional shares of our common stock issued to RareGen members upon the achievement of revenue targets in RareGen management’s forecast. The Transaction Committee discussed the appropriate valuation for the shares of our common stock to be issued to RareGen members in the merger, and determined that the price per share should be fixed at the time of execution of a definitive agreement, based on the 30-day volume weighted average trading prices for our common stock, or 30-day VWAP. The Transaction Committee also discussed the terms of the proposed PIPE financing, including the issuance price per share based on the 30-day VWAP for our common stock. The Transaction Committee authorized our management to execute the non-binding term sheet and continue discussions with RareGen, PBM and Party X with respect to the transactions described in the term sheet.

On April 9, 2020, we executed a non-binding term sheet with RareGen and Party X which, among other things, contemplated a reverse subsidiary merger, pursuant to which members of RareGen would receive $40 million of our common stock in the aggregate at closing, and up to $12.5 million of additional shares of our common stock issuable to the RareGen members upon achievement of certain revenue milestones, in each case valued at our 30-day VWAP at the time of the execution of a definitive agreement. The term sheet also provided for a simultaneous $60 million PIPE financing, priced at our 30-day VWAP at the time of execution of the definitive agreement, the appointment of representatives of PBM, RareGen, and Party X to the combined company board of directors, and a carve-out for the pending United Therapeutics/ Smiths Medical litigation.

On April 14, 2020, we formally engaged Jefferies as our financial advisor to assist in our evaluation of the acquisition of RareGen.

Discussions among us, RareGen and Party X continued following the execution of the term sheet, including with respect to tax, accounting and structuring matters. To address certain tax and accounting matters arising out of the proposed reverse subsidiary merger structure, the parties discussed structuring our

TABLE OF CONTENTS

acquisition of RareGen using a holding company structure, where each of Liquidia Technologies and RareGen would become wholly-owned subsidiaries of a new publicly traded holding company. Discussions also continued with respect to the Sandoz Promotion Agreement, and RareGen’s efforts to obtain Sandoz’s consent to a change of control that would result from the proposed acquisition of RareGen.

On April 29, 2020, DLA Piper, as instructed by the Transaction Committee, sent a draft of a common stock purchase agreement with respect to the proposed PIPE financing to Party X’s legal counsel. The draft agreement provided for the issuance of $60.0 million in new shares of our common stock to investors led by Party X at a price based on our 30-day VWAP on the date of execution of definitive agreements. The draft agreement also contemplated that a portion of the shares of our common stock to be purchased by Party X and the investors, not to exceed 19.99% of our outstanding shares of common stock, would be purchased concurrent with execution of the Merger Agreement, and the remaining shares would be purchased concurrent with closing of the Merger Transaction.

On May 8, 2020, representatives of RareGen informed our management that RareGen had reached an agreement with Sandoz, pursuant to which RareGen and Sandoz would amend the Promotion Agreement to modify, among other things, the non-compete provisions, change in control provisions, and economic terms of the Promotion Agreement.

On May 12, 2020, the Transaction Committee met, with our management and representatives of DLA Piper in attendance. Representatives of DLA Piper updated the Transaction Committee on the status of discussions with RareGen and Party X and certain legal and process matters. Representatives of DLA Piper presented a summary of the draft Merger Agreement, including the transaction structure, covenants, conditions to closing, indemnification provisions and termination provisions, which our management proposed to use as the basis for discussion with RareGen. Representatives of DLA Piper also reviewed a summary of a draft registration rights agreement, with respect to the shares of our common stock to be issued to RareGen in the Merger Transaction and Party X in the PIPE financing. Our management informed the Transaction Committee that Party X was seeking assurance that there would be sufficient support from our existing stockholders to approve the Merger and the issuance of shares of our common stock in excess of 19.99% in the PIPE financing, as required by Nasdaq stockholder approval rules. Representatives of DLA Piper presented a summary of a draft support agreement, pursuant to which certain of our large stockholders would agree to support the Merger Transaction and vote to approve the Merger Agreement. The Transaction Committee discussed contacting certain of our existing stockholders seeking their support for the proposed transactions and gauging their potential interest in participating in the PIPE financing. The Transaction Committee authorized DLA Piper to send the draft Merger Agreement, Support Agreement and Registration Rights Agreement to RareGen and Party X, and authorized our management to contact certain of our existing stockholders to gauge their support for the transactions and their interest in participating in the PIPE financing.

In accordance with the Transaction Committee’s instructions, our management contacted certain of our largest stockholders, including representatives of Eshelman Ventures, LLC and Canaan VIII L.P. to discuss whether they would be supportive of the proposed Merger Transaction and whether they would be interested in participating in the PIPE financing. Our management also informed such stockholders that RareGen and Party X would require a support agreement from our large stockholders, pursuant to which such stockholders would agree to vote to approve the Merger Agreement.

On May 12, 2020, DLA Piper, as instructed by the Transaction Committee, sent a draft of the Merger Agreement, to Cooley, legal counsel to RareGen, RareGen and PBM.

On May 12, 2020, DLA Piper, as instructed by the Transaction Committee, sent a draft of the Registration Rights Agreement and Support Agreement to Party X’s legal counsel.

Beginning in May 2020, the Transaction Committee met weekly by telephonic conference with, our management and advisors, and the Transaction Committee was given updates on the status of due diligence and negotiation of the transaction documents. The Transaction Committee provided guidance to our management and advisors with respect to issues raised in negotiations of the transaction documents and issues raised in due diligence.

TABLE OF CONTENTS

On May 28, 2020, our board of directors met, with our management, representatives of DLA Piper and representatives of Jefferies in attendance. Our board of directors reviewed our strategic plan and forecasts under various business scenarios, and reviewed forecasts prepared by our management for RareGen, including estimates of synergies that could be realized from the potential transaction. Representatives of Jefferies reviewed the status of discussions with RareGen, PBM and Party X, and presented our board of directors with its preliminary financial analysis of the proposed transaction. Representatives of DLA Piper summarized the key terms of the Merger Agreement, Support Agreement, Registration Rights Agreement and Common Stock Purchase Agreement related to the PIPE financing, and the issues that remained open, which included indemnification matters, post-closing adjustments to the merger consideration, representations, warranties and covenants applicable to each of us and RareGen, closing conditions, expense reimbursement and the termination fee, among others. Our board of directors discussed the open issues, including how to value holdback shares supporting RareGen’s indemnification obligations, the appropriate percentage of shares to be held back at closing to support RareGen’s indemnification obligations, the events giving rise to our termination rights, the amount of termination fee payable by us if we were to terminate the Merger Agreement under certain circumstances, and expense reimbursement if our stockholders do not approve the Merger Agreement. Our board of directors discussed the benefits of the proposed Merger Transaction, including the potential for achieving cost synergies, a stronger balance sheet, enhanced access to financing sources and the potential for positive cash flow and profitability quicker than we could achieve on a stand-alone basis. Our board of directors instructed our management to continue negotiations with RareGen and Party X, with guidance from the Transaction Committee,

On May 28, 2020, our Compensation Committee approved fees payable to members of the Transaction Committee as compensation for the additional time and effort spent on the proposed transactions, which consisted of $5,000 to each member of the Transaction Committee and $10,000 to the Chairperson of the Transaction Committee, each on a quarterly basis.

Also on May 28, 2020, the Transaction Committee met with representatives of DLA Piper and Jefferies to discuss the status of negotiations between RareGen, Party X and us, and the terms of the amendment to the Sandoz Promotion Agreement with RareGen, which is described in detail on page 61. At the meeting, the Transaction Committee formally appointed Mr. Kirsch as chairman of the Transaction Committee.

On June 11, 2020, the Transaction Committee met with our management and representatives of DLA Piper and Jefferies. Our management reviewed the forecasts provided by RareGen management and the adjustments made by our management to such forecasts. The Transaction Committee also discussed the amendment to the Sandoz Promotion Agreement, and strategic opportunities in the broader treprostinil market, among other things. Our management also reviewed with the Transaction Committee the draft RareGen financial statements provided by RareGen management for the most recent fiscal year and interim period. Representatives of DLA Piper and Jefferies provided an update on the status of negotiations on the Merger Agreement and PIPE financing documents. Open points on the Merger Agreement included closing conditions, indemnification procedures, termination rights and the termination fee. The Transaction Committee also discussed the recent increase in the trading prices of our common stock, and the possible implications for the negotiation of the Merger Agreement and the PIPE financing documents.

On June 15, 2020, our board of directors met, with representatives of Jefferies and DLA Piper in attendance. Representatives of Jefferies discussed the recent increase in the trading price of our common stock, which had increased from $5.50 per share on April 9, 2020, the date the non-binding term sheet was executed by us, RareGen and Party X, to $7.60 at the opening of trading on June 15, 2020. Our board of directors discussed the pricing of the potential PIPE financing given our recent stock price performance. Our board of directors instructed Jefferies to contact Party X to confirm that the issue price tied to the 30-day VWAP in the term sheet would still be acceptable to the potential PIPE investors in light of the increase in stock price.

On June 15, 2020, in accordance with the instructions of our board of directors, representatives of Jefferies contacted Party X. Party X responded that they would not agree to a price per share greater than $6.00 in the potential PIPE financing, which reflected the 30-day VWAP at the time the term sheet was executed. Representatives of Jefferies promptly informed our management of Party X’s response to our board

TABLE OF CONTENTS

of directors’ request for an increase in the issue price for the PIPE financing. Between June 15, 2020 and June 24, 2020, additional discussions relating to the issue price for the PIPE financing took place between Jefferies and Party X.

On June 24, 2020, the Transaction Committee met with members of our management and representatives of Jefferies and DLA Piper in attendance, to discuss financing alternatives given our recent stock price performance, among other things. Representatives of Jefferies reviewed our recent stock price performance with the Transaction Committee, and noted that our stock price had risen from a closing price of $5.50 on April 9, 2020 (the date the term sheet was signed) to a closing price of $11.00 on June 24, 2020. The Transaction Committee discussed the potential benefits of pursuing an underwritten public offering at a price greater than $6.00, and abandoning the PIPE financing. The Transaction Committee determined it was in the best interest of our stockholders to discontinue the PIPE financing discussions and proceed with a public offering at a price that more appropriately reflected the value of our common stock under current market conditions.

On June 25, 2020, we informed Party X that we were discontinuing the PIPE financing discussions, given our recent stock price performance. All activity in connection therewith was terminated and any offers to buy or indications of interest given in the private offering were rejected or otherwise not accepted.

We also informed RareGen that we would not be moving forward with the PIPE financing, but would instead be pursing an underwritten public offering of common stock that we intended to launch concurrently with the execution of the Merger Agreement. Our negotiations with RareGen continued, and the parties resolved all remaining open issues, including a termination fee of $7.5 million if we terminate the Merger Agreement under certain circumstances. We and RareGen also continued negotiations with certain of our stockholders, including Eshelman Ventures, LLC, Canaan VIII LP, Neal Fowler and certain other large stockholders in our company, and such stockholders agreed to enter into the Support Agreements described on page 138 under the heading “The Merger Agreement — Agreements Entered Into in Connection with the Merger Agreement: Support Agreements”. We and RareGen also reached agreement on certain governance matters, including the composition of the board of directors of HoldCo, as reflected in the Cooperation Agreements described on page 135 under the heading “The Merger Agreement — Agreements Entered Into in Connection with the Merger Agreement: Cooperation Agreements beginning on page 135. RareGen members agreed to restrictions on their ability to transfer HoldCo shares for six months after the closing of the Merger Transaction. Finally, we and RareGen agreed to the terms on which the United Therapeutics/ Smiths Medical litigation will be funded and any settlement proceeds distributed, as set forth in the Litigation Funding and Indemnification Agreement described on page 139 under the heading “The Merger Agreement — Agreements Entered Into in Connection with the Merger Agreement: Litigation Funding and Indemnification Agreement”.

On June 28, 2020, our board of directors met, with our management and representatives of Jefferies and DLA Piper in attendance. Representatives of Jefferies presented its financial analysis of the proposed Merger Transaction, including the relative values of us and RareGen under various business scenarios. Jefferies then delivered its oral opinion to our board of directors, subsequently confirmed in writing on June 29, 2020, that as of June 29, 2020, and based upon and subject to the factors and assumptions set forth therein, the number of shares of HoldCo common stock to be received by holders of our common stock in the Merger Transaction pursuant to the Merger Agreement was fair from a financial point of view to such holders. Representatives of DLA Piper provided an update on the status of the transaction documents, including the Support Agreements. Our board of directors discussed the benefits and risks of proceeding with the RareGen acquisition, and following such deliberations, our board of directors determined that it was in the best interests of our stockholders to enter into the Merger Agreement and consummate the Merger Transactions, and approved the execution and delivery of the Merger Agreement by our management and consummation of the Merger Transactions. Our board of directors also approved launching the confidentially marketed public offering on the morning on June 29, 2020.

On June 29, 2020, the Merger Agreement was executed and we issued a joint press release with RareGen at approximately 4:01 p.m. announcing the Merger Transaction. Also on June 29, 2020, a Pricing Committee of our board of directors met and approved the terms of the public offering. Shortly thereafter, we issued a press release announcing the launch of the public offering.

Liquidia’s Reasons for the Merger Transaction

In reaching its decision to approve and declare the advisability of the Merger Agreement and the Liquidia Merger, our board of directors, including the transaction committee of our board of directors, consulted with our management and our financial and legal advisors, and considered a number of factors. In its decision to recommend and approve the Merger Transaction, the factors identified by our board of directors, including the transaction committee of our board of directors, were the following:

•

the potential strategic benefits of the Merger Transaction including:

•

the generation of cash flow through sales of a generic version of Remodulin®, which is a parenteral formulation of treprostinil, for the treatment of PAH from RareGen operations;

•

the belief that HoldCo will be better positioned to provide a broader PAH product offering to patients comprised of both LIQ861, a potential first-to-market inhaled dry powder treprostinil that can be delivered using a convenient, palm-sized dry powder inhaler, and a generic version of Remodulin®;

•

adding supportive stockholders which are vested in HoldCo’s long-term success;

•

adding new directors to HoldCo’s board of directors which have many years of PAH experience at peer biotechnology and pharmaceutical companies as well as many years of public company director experience;

•

the potential to leverage RareGen’s existing sales force and sales experience to market our product candidates;

•

the potential to leverage RareGen’s commercial strategy, scalable PAH infrastructure, marketing capabilities and relationships with hospitals, specialty pharmacies and national and regional payers to successfully commercialize our product candidates; and

•

the increased financial strength and operational efficiencies that HoldCo can potentially deliver.

•

historical information concerning our and RareGen’s respective businesses, prospects, financial performance and condition, operations, technology, management and competitive position, including the results of operations for each company;

•

our management’s view of the financial condition, results of operations and businesses of us and RareGen before and after giving effect to the Merger Transaction including:

•

the belief that HoldCo could experience faster revenue growth, with a broader portfolio and a larger national infrastructure, and achieve positive cash flow and profitability quicker than we could on a stand-alone basis;

•

the belief that HoldCo’s balance sheet will be viewed by investors as stronger than our balance sheet on a stand-alone basis and that HoldCo could therefore be considered as more financially viable;

•

the belief that HoldCo will be able to achieve cost synergies; and

•

the belief that HoldCo will have enhanced access to financing sources necessary to fund its business as compared to our access on a stand-alone basis;

•

current financial market conditions and historical market prices, volatility and trading information with respect to our common stock reflecting, among other things, a shortage of analyst coverage, institutional support and investor interest, which potentially could be improved as part of a larger combined company;

•

the consideration to be received by our stockholders and RareGen’s members as a result of the Merger Transaction and a comparison of comparable transactions;

•

the belief that the terms of the Merger Agreement, including the parties’ representations, warranties and covenants, and the conditions to their respective obligations, are reasonable;

•

the diminished prospects of our company as an independent company when compared to the prospects of us and RareGen as a combined entity;

TABLE OF CONTENTS

•

the potential for other third parties to enter into strategic relationships with or to acquire us or RareGen;

•

financial analysis prepared by Jefferies, which is described in the section entitled “— Opinion of Jefferies LLC” beginning on page 98, with respect to the companies presented to our board of directors;

•

the presentation by representatives of Jefferies, including Jefferies’ opinion dated as of June 29, 2020, that subject to the various assumptions made, procedures followed, matters considered and limitations and qualifications on the scope of the review undertaken by Jefferies as described in its opinion, the number of shares of HoldCo common stock to be received by our stockholders in the Liquidia Merger pursuant to the Merger Agreement was fair, from a financial point of view, to the holders of our common stock (please read Annex B carefully and see the section entitled “— Opinion of Jefferies LLC” beginning on page 98);

•

the intention that the Merger Transaction will qualify as a tax-free exchange for our stockholders for United States federal income tax purposes;

•

the nature of our stockholder constituency and the absence of voting agreements that “lockup” the vote of our stockholders, with the exception of the Support Agreements, with regard to the adoption of the Merger Agreement;

•

the expected impact of the Merger Transaction on HoldCo’s future customers. Our board of directors believes that HoldCo’s future customers will likely benefit from:

•

a broader PAH product portfolio and an experienced national sales force;

•

strategic partners, who may enjoy a greater geographic reach and additional customer solutions; and

•

employees who may have an opportunity to grow with an organization that has better financial backing and expanded market opportunities; and

•

the results of the due diligence investigation of RareGen performed by our management, legal and financial advisors, and market research reports, which underscored the belief of our board of directors that the Merger Transaction represents a reasonable and fair transaction to us and our stockholders.

Our board of directors, including the transaction committee of our board of directors, also identified and considered the following potentially negative factors in its deliberations concerning the Merger Transaction:

•

the risk that the potential benefits sought in the Merger Transaction might not be fully realized;

•

the possibility that the Merger Transaction might not be completed despite the parties’ efforts, even if approved by our stockholders;

•

the effect of public announcement of the Merger Transaction on:

•

our ability to attract and retain key management, marketing and commercial personnel, and

•

the progress and status of certain projects and strategic relationships;

•

the substantial charges to be incurred in connection with the Merger Transaction, including the costs of integrating the businesses and the Merger Transaction expenses arising from the Merger Transaction;

•

the risk that, despite the efforts of HoldCo, key personnel might not remain employed by HoldCo;

•

the challenges of integrating the businesses of us and RareGen;

•

the risk associated with the fact that HoldCo will be controlled by a select few stockholders who will be able to exercise significant control over the corporate activities of HoldCo; and

•

various other risks described in the section entitled “Risk Factors” beginning on page 36.

The foregoing discussion includes the material factors considered by our board of directors. In view of the complexity and wide variety of information and factors, both positive and negative considered by our

TABLE OF CONTENTS

board of directors, it did not find it practical to quantify, rank or otherwise assign relative or specific weights to the factors considered. In addition, our board of directors did not reach any specific conclusion with respect to each of the factors considered, or any aspect of any particular factor. Instead, our board of directors conducted an overall analysis of the factors described above, including discussions with our management and legal, financial and accounting advisors. In considering the factors described above, individual members of our board of directors may have given different weight to different factors.

Recommendation of the Liquidia Technologies Board of Directors

After careful consideration of all of the factors described above, our board of directors determined that the Merger Agreement and the proposed Merger Transaction are advisable, fair to, and in the best interests of, us and our stockholders. Our board of directors recommends that our stockholders vote FOR adoption of the Merger Agreement and approval of the Liquidia Merger.

RareGen’s Reasons for the Merger Transaction

the ability of RareGen to retain its sales force and recruit new employees with a broader product portfolio and broader business;

•

the potential to maximize the value of RareGen’s existing sales force and sales experience by creating an opportunity to market additional product candidates;

•

the potential to maximize the value of RareGen’s commercial strategy, scalable PAH infrastructure, marketing capabilities and relationships with hospitals, specialty pharmacies and national and regional payers by creating an opportunity to market additional product candidates; and

Opinion of Jefferies LLC

We have retained Jefferies as our financial advisor in connection with the Merger Transaction. In connection with this engagement, we requested that Jefferies evaluate the fairness, from a financial point of view, of the number of shares of HoldCo common stock to be received by holders of our common stock in the Liquidia Merger pursuant to the Merger Agreement. At a meeting of our board of directors held on June 28, 2020, Jefferies rendered an oral opinion, confirmed by delivery of a written opinion dated June 29, 2020, to our board of directors to the effect that, as of that date and based on and subject to the various assumptions made, procedures followed, matters considered and limitations and qualifications on the scope of review undertaken as described in its opinion, the number of shares of HoldCo common stock to be received by holders of our common stock in the Liquidia Merger pursuant to the Merger Agreement was fair, from a financial point of view, to such holders.

The full text of Jefferies’ opinion, which describes the assumptions made, procedures followed, matters considered and limitations and qualifications on the scope of review undertaken by Jefferies in rendering its opinion, is attached as Annex B to this proxy statement/prospectus and is incorporated herein by reference. Jefferies’ opinion is for the use and benefit of our board of directors (in its capacity as such) in its consideration of the Merger Transaction, and Jefferies’ opinion does not address the relative merits of the Merger Transaction contemplated by the Merger Agreement as compared to any alternative transaction or opportunity that might be available to our company, nor does it address the underlying business decision by our company to engage in the Merger Transaction or the terms of the Merger Agreement or the documents referred to therein.

TABLE OF CONTENTS

Jefferies’ opinion does not constitute a recommendation as to how any holder of our common stock should vote or act in connection with the Merger Transaction or any other matter. The following summary is qualified in its entirety by reference to the full text of Jefferies’ opinion.

In arriving at its opinion, Jefferies, among other things:

(i)

reviewed a draft of the Merger Agreement provided to it on June 26, 2020;

(ii)

reviewed certain publicly available financial and other information about our company;

(iii)

reviewed certain information furnished to it by our management, relating to the business, operations and prospects of our company, including financial forecasts and analyses under various business assumptions;

(iv)

reviewed certain information furnished to it by our management, relating to the business, operations and prospects of RareGen, including financial forecasts and analyses under various business assumptions;

(v)

reviewed certain information furnished to it by the management of RareGen, relating to the business, operations and prospects of RareGen, including financial forecasts and analyses under various business assumptions, and held discussions with senior management of RareGen about such matters;

(vi)

reviewed information relating to certain financial and operational benefits and operating synergies (including the amount and timing thereof) anticipated by our management to result from the Merger Transaction, and approved for Jefferies’ use by our company, which Jefferies referred to as “synergies”;

(vii)

considered the potential pro forma impact of the Merger Transaction;

(viii)

held discussions with members of senior our management concerning the matters described in clauses (ii) through (vii) above;

(ix)

reviewed the proposed financial terms of the Merger Transaction and compared them with the publicly available financial terms of certain other transactions that Jefferies deemed relevant; and

(x)

conducted such other financial studies, analyses and investigations as Jefferies deemed appropriate.

In its review and analysis and in rendering its opinion, Jefferies assumed and relied upon, but did not assume any responsibility to independently investigate or verify, the accuracy and completeness of all financial and other information that was supplied or otherwise made available by our company or that was publicly available to Jefferies (including, without limitation, the information described above), or that was otherwise reviewed by Jefferies. Jefferies relied on assurances of our management that it is not aware of any facts or circumstances that would make such information inaccurate or misleading. In its review, Jefferies did not obtain any independent evaluation or appraisal of any of the assets or liabilities of, nor did Jefferies conduct a physical inspection of any of the properties or facilities of our company, RareGen or HoldCo, nor has Jefferies been furnished with any such evaluations or appraisals of such physical inspections, nor did Jefferies assume any responsibility to obtain any such evaluations or appraisals.

With respect to the financial forecasts provided to and examined by Jefferies, Jefferies noted that projecting future results of any company is inherently subject to uncertainty. With respect to the forecasts of our company and RareGen prepared by our management and provided to Jefferies by our management for use by Jefferies, we informed Jefferies, and Jefferies assumed, that such financial forecasts were reasonably prepared on bases reflecting the best currently available estimates and good faith judgments of our management as to the future financial performance of our company and RareGen. With respect to the future financial performance of HoldCo giving pro forma effect to the Merger Transaction, at our board of directors’ instruction and with its consent, Jefferies assumed that the synergies will be realized in the amounts and at the times projected. Jefferies expressed no opinion as to the financial forecasts prepared by our management or the assumptions on which they are made, including the synergies. In addition, at our board of directors’ instruction for informational purposes that were not considered part of Jefferies

TABLE OF CONTENTS

financial analyses for its opinion, Jefferies performed certain financial analysis using the financial forecasts prepared by management of RareGen. Jefferies expressed no opinion as to the financial forecasts prepared by RareGen or the assumptions on which they are made.

Jefferies’ opinion is based on economic, monetary, regulatory, market and other conditions existing and which could be evaluated as of June 29, 2020. Jefferies expressly disclaimed any undertaking or obligation to advise any person of any change in any fact or matter affecting its opinion of which Jefferies becomes aware after June 29, 2020.

Jefferies made no independent investigation of any legal or accounting matters affecting us, RareGen and HoldCo, and Jefferies assumed the correctness in all respects material to its analysis of all legal and accounting advice given to our company and our board of directors, including, without limitation, advice as to the legal, accounting and tax consequences of the terms of, and transactions contemplated by, the Merger Agreement to our company, RareGen and HoldCo. Jefferies assumed that the Merger Transaction will be consummated in accordance with the terms of the Merger Agreement without waiver, modification or amendment of any term, condition or agreement and in compliance with applicable laws, documents and other requirements and that the final form of the Merger Agreement would be substantially similar to the draft dated June 26, 2020 previously provided to Jefferies. Jefferies also assumed that in the course of obtaining the necessary regulatory or third party approvals, consents and releases for the Merger Transaction, no delay, limitation, restriction or condition would be imposed that would have an adverse effect on us, RareGen or HoldCo or the contemplated benefits of the Merger Transaction in any respect material to Jefferies’ opinion. Jefferies expressed no opinion as to the price shares of HoldCo common stock will trade at any time in the future.

Jefferies’ opinion was provided for the use and benefit of our board of directors in its consideration of the transactions contemplated by the Merger Agreement, and Jefferies’ opinion does not address the relative merits of the transactions contemplated by the Merger Agreement as compared to any alternative transaction or opportunity that might be available to us, nor did it address the underlying business decision by our company to engage in the transactions contemplated by the Merger Agreement. Jefferies opinion did not take into account the underwritten public offering of 9,375,000 shares of our common stock completed in July 2020. In addition, we did not ask Jefferies to address, and the opinion did not address, the fairness to, or any other consideration of, the holders of any class of securities, creditors or other constituencies of our company. Jefferies’ opinion was authorized by the Fairness Committee of Jefferies LLC.

In connection with rendering its opinion to our board of directors, Jefferies performed a variety of financial and comparative analyses, which are summarized below. The following summary is not a complete description of all analyses performed and factors considered by Jefferies in connection with its opinion. The preparation of a fairness opinion is a complex process involving various determinations as to the most appropriate and relevant quantitative and qualitative methods of financial analysis and the applications of those methods to the particular circumstances and, therefore, is not necessarily susceptible to partial analysis or summary description. Jefferies believes that its analyses must be considered as a whole. Considering any portion of Jefferies’ analyses or the factors considered by Jefferies or focusing on information presented in tabular format, without considering all analyses and factors or the narrative description of the analyses, could create a misleading or incomplete view of the processes underlying Jefferies’ analyses and opinion. Jefferies did not draw, in isolation, conclusions from or with regard to any one factor or method of analysis for purposes of its opinion, but rather arrived at its ultimate opinion based on the results of all analyses undertaken by it and assessed as a whole.

With respect to the selected transactions analysis summarized below, no company or transaction used as a comparison was identical or directly comparable to our company, RareGen or the Merger Transaction. This analysis necessarily involved complex considerations and judgments concerning financial and operating characteristics and other factors that could affect the acquisition or other values of the companies or transactions concerned.

The estimates of the future performance of our company, RareGen and HoldCo in or underlying Jefferies’ analyses are not necessarily indicative of future results or values, which may be significantly more or less favorable than those estimates. In performing its analyses, Jefferies considered industry performance, general business, economic, monetary, regulatory, market and other conditions and other matters, many

100

TABLE OF CONTENTS

of which were beyond the control of our company and Jefferies. Estimates of the financial value of companies do not purport to be appraisals or necessarily reflect the prices at which companies or securities actually may be sold or acquired. Accordingly, the estimates used in, and the range of the valuations resulting from, any particular analysis described below are inherently subject to substantial uncertainty and should not be taken as Jefferies’ view of the actual value of our company, RareGen, HoldCo or our or their respective securities.

The number of shares of HoldCo common stock to be received by holders of our common stock pursuant to the Merger Agreement was determined through negotiations between us and RareGen, and our decision to enter into the Merger Agreement was solely that of our board of directors. Jefferies’ opinion and financial analyses were only one of many factors considered by our board of directors in its evaluation of the number of shares of HoldCo common stock to be received by holders of our common stock in the Liquidia Merger and should not be viewed as determinative of the views of our board of directors or management with respect to the Merger Transaction or the number of shares of HoldCo common stock to be received by holders of our common stock in the Liquidia Merger.

Financial Analyses

The following is a summary of the material financial analyses provided to our board of directors and performed by Jefferies in connection with its opinion. The financial analyses summarized below include information presented in tabular format. In order to fully understand Jefferies’ financial analyses, the tables must be read together with the text of each summary. The tables alone do not constitute a complete description of the financial analyses. Considering the data below without considering the full narrative description of the financial analyses, including the methodologies and assumptions underlying the analyses, could create a misleading or incomplete view of Jefferies’ financial analyses. For purposes of the financial analyses described below, (i) the term “unlevered free cash flow” refers to a calculation of the future cash flows generated by an asset without including in such calculation any debt servicing costs, (ii) the term “our company forecasts” means financial forecasts and estimates relating to our company prepared by our management, (iii) the term “our RareGen forecasts” means financial forecasts and estimates relating to RareGen prepared by our management and (iv) the term “RareGen management forecasts” means financial forecasts and estimates relating to RareGen prepared by management of RareGen. For purposes of its analysis, Jefferies did not take into account the underwritten public offering of 9,375,000 shares of our common stock completed in July 2020 or any future financings that may be completed by us or HoldCo in the future.

RareGen Selected Transactions Analysis. Jefferies reviewed financial data relating to 17 precedent transactions announced since July 1, 2014, to the extent publicly available, involving the sale of generic products or generic product portfolios, which given their business and financial characteristics, including lack of R&D spend and pipeline products, Jefferies considered relevant for purposes of its analysis of RareGen, which is a single product company with no R&D spend or product pipeline.

Jefferies reviewed, among other information, transaction values of the selected transactions, calculating the consideration paid for the products as a multiple of such product or product portfolio’s latest 12 months revenue as of the applicable announcement date. Financial data of the selected transactions were based on public filings and other publicly available information. Financial data of RareGen was based on internal estimates of RareGen management which Jefferies was instructed to use by our management.

The overall low to high latest 12 months revenue multiples observed for the selected transactions announced since January 1, 2018 were 0.1x to 1.7x with a median of 1.1x and a mean of 1.0x. The overall low to high latest 12 months revenue multiples observed for the selected transactions announced between July 1, 2014 and January 1, 2018 were 2.0x to 6.7x with a median of 2.7x and a mean of 3.0x. Jefferies calculated separate multiple ranges for the periods before and after January 1, 2018 because changes in the generic pharmaceutical market in recent years made pre-2018 transactions (which had higher multiples) less relevant for its analysis. Jefferies then applied a selected range of 1.0x to 2.5x latest 12 months revenue multiples derived from the selected transactions to RareGen’s latest 12 months (as of March 31, 2020) RareGen/Sandoz net sales of $27.5 million (prior to the allocation of “Net Profits” under the Promotion Agreement with Sandoz (as described on page 70 of this proxy statement/prospectus)), and RareGen’s latest 12 months (as of March 31, 2020) adjusted net sales of $22.0 million. Jefferies calculated adjusted net sales for RareGen by dividing RareGen’s gross profit for the period by RareGen’s gross profit percentage for such period, without giving effect to the allocation of “Net Profits” under the Promotion Agreement with Sandoz. This analysis indicated the following approximate implied equity value reference ranges for RareGen:

102

TABLE OF CONTENTS

Financial Metrics			Implied RareGen Equity Value
LTM (3/30/20) RareGen/Sandoz Net Sales			$27.0 – $69.0 million
LTM (3/20/20) Adjusted Net Sales			$22.0 – $55.0 million

RareGen Discounted Cash Flow Analysis. Jefferies performed a discounted cash flow analysis of RareGen, using a perpetuity growth rate approach, to calculate a range of implied present values of the unlevered free cash flows that RareGen was forecasted to generate through the full fiscal year ending December 31, 2024 utilizing our RareGen forecasts (disclosed at page 106 of this proxy statement/prospectus), both with and without synergies estimated by our management and assuming various launch dates for LIQ861 provided by our management. Terminal values of RareGen were calculated by applying to RareGen’s unlevered free cash flows for the fiscal year ending December 31, 2024 a selected range of perpetuity growth rates of (20.0%) to 0.0%, which range was selected by Jefferies in its professional judgement. The present values (as of March 31, 2020) of the cash flows and terminal values were then calculated using a selected discount rate range of 9.7% to 10.7%, which were based on the estimated weighted average cost of capital of RareGen derived by application of the capital asset pricing model. This analysis indicated the following approximate implied equity value reference range for RareGen:

			Implied RareGen Equity Value
Liquidia Technologies case (no synergies)			$26.0 – $56.0 million
Liquidia Technologies case (with synergies)			$36.0 – $66.0 million

The discounted cash flow analysis is a widely used valuation methodology, but the results of such methodology are highly dependent on the assumptions that must be made, including revenue growth rates, cash flow estimates, terminal values and discount rates. The analysis did not purport to be indicative of the actual values or expected values of RareGen.

Liquidia Technologies Sum of the Parts Discounted Cash Flow Analysis. Using our company forecasts (disclosed at page 106 of this proxy statement/prospectus) prepared by our management and assuming various launch dates for LIQ861 provided by our management, Jefferies performed a sum-of-the-parts discounted cash flow analysis to derive an implied range of stand-alone equity values for our company. Using a mid-year convention and discount rates ranging from 9.7% to 10.7%, reflecting estimates of our weighted average cost of capital derived by application of the capital asset pricing model, Jefferies discounted to present value as of March 31, 2020 estimates of the free cash flows to be generated by LIQ861 through December 31, 2037, assuming various product launch dates, all as reflected in our forecasts. Jefferies then derived a range of implied equity values for our company by adding (a) POS adjusted estimates of the free cash flows to be generated from LIQ861, assuming various product launch dates, in each case through December 31, 2037, and (b) the estimated value of our platform, pipeline and PRINT technology, with respect to which our management instructed Jefferies to assume a value of $40.0 million. This analysis indicated an implied equity value reference range of $238.2 million to $268.1 million for our company.

Relative Value Financial Analysis. Jefferies performed a relative value analysis by comparing the implied equity values for our company on a stand-alone basis resulting from the sum-of-the-parts discounted cash flow analysis described above, with the implied equity value ranges for RareGen resulting from the selected precedent analysis, and discounted cash flow analysis for RareGen, with and without synergies. This analysis yielded the following ranges of implied relative equity values on a percentage basis for RareGen and our company.

Jefferies then compared the percentage of shares of HoldCo common stock to be issued to RareGen’s members in the Merger Transaction, which is 17.7% of the shares of Holdco common stock on a fully diluted basis, to the implied equity value ranges for RareGen, relative to our company expressed on a percentage basis. Jefferies considered that in the Merger Transaction holders of our common stock will receive one share of HoldCo common stock for each share of our common stock, representing 82.3% of the shares of HoldCo common stock on a fully-diluted basis.

Certain Additional Information

At the request of our board of directors, Jefferies performed an illustrative discounted cash flow analysis using the RareGen management forecasts, which assumes that RareGen achieves its 2021 net sales target (as calculated pursuant to the Promotion Agreement) and 2,083,333 additional shares of HoldCo are issued to RareGen members. Utilizing the RareGen management forecasts and using a perpetuity growth rate approach, Jefferies calculated a range of implied present values of the unlevered free cash flows that RareGen management had forecasted RareGen to generate through the full fiscal year ending December 31, 2024. Terminal values of RareGen were calculated by applying to RareGen’s unlevered free cash flows for the fiscal year ending December 31, 2024 a selected range of perpetuity growth rates of (20.0%) to 0.0%, which range was selected by Jefferies in its professional judgement. The present values (as of March 31, 2020) of the cash flows and terminal values were then calculated using a selected discount rate range of 9.7% to 10.7%, which were based on the estimated weighted average cost of capital of RareGen derived by application of the capital asset pricing model. This analysis indicated an implied equity value reference range for RareGen of $56.0 million to $108.0 million. Jefferies then performed an illustrative relative value analysis by comparing the implied equity value reference range for RareGen resulting from the discounted cash flow analysis using the RareGen management forecasts with the implied equity value range of $238.2 million to $268.1 million for our company resulting from the sum-of-the-parts discounted cash flow analysis described above. Jefferies observed that the resulting implied relative equity value range using RareGen management forecasts represented 17.4% to 31.2% for RareGen, as compared to 68.8% to 82.6% for our company. The illustrative discounted cash flow analysis and illustrative relative value analysis using RareGen management forecasts was not considered part of Jefferies financial analyses for its opinion but rather were noted for informational purposes.

Miscellaneous

We have agreed to pay Jefferies a fee of $2.5 million, a portion of which was payable upon delivery of Jefferies’ opinion and the remainder of which is contingent upon consummation of the Merger Transaction. We have also agreed to reimburse Jefferies for expenses, including fees and expenses of counsel, incurred in connection with Jefferies’ engagement, and to indemnify Jefferies and related parties against liabilities arising out of or in connection with the services rendered and to be rendered by Jefferies under its engagement.

In the past two years, Jefferies has provided financial advisory and financing services to our company, including (i) acting as a bookrunner for the initial public offering of our common stock in July 2018, (ii) acting

104

TABLE OF CONTENTS

as a bookrunner in an offering of our common stock in March 2019, (iii) acting as a placement agent in a private placement of our common stock in December 2019, and (iv) acting as a placement agent for our ATM facility in December 2019-February 2020, for which we have received aggregate fees of less than $5.0 million. Jefferies acted as a bookrunner in a public offering of our common stock in July 2020, for which Jefferies received a fee of $3.87 million. In addition, Jefferies maintains a market in the securities of our company, and in the ordinary course of its business, Jefferies and its affiliates may trade or hold securities of our company, RareGen, HoldCo and/or our or their respective affiliates for its own account and for the accounts of its customers and, accordingly, may at any time hold long or short positions in those securities. In addition, Jefferies may seek to, in the future, provide financial advisory and financing services to our company, RareGen, HoldCo or entities that are affiliated with us, RareGen or HoldCo, for which Jefferies would expect to receive compensation.

Jefferies was selected to act as our financial advisor in connection with the Merger Transaction because, among other factors, Jefferies is an internationally recognized investment banking firm with substantial experience in merger and acquisition transactions, its familiarity with our company and our business and reputation. Jefferies is regularly engaged in the valuation of businesses and securities in connection with mergers and acquisitions, leveraged buyouts, negotiated underwritings, competitive bids, secondary distributions of listed and unlisted securities and private placements.

Certain Liquidia and RareGen Forward-Looking Financial Information

Prior to approval by our board of directors of the Merger Transaction, the execution of the Merger Agreement and the consummation of the transactions contemplated by the Merger Agreement, our management prepared certain forward-looking financial information on a stand-alone, pre-transaction basis for each of our company and RareGen. The forward-looking financial information prepared by our management is on a standalone basis and is not intended to be added together, and adding together the forward-looking financial information for the two companies would not represent the results that HoldCo will achieve if the Merger Transaction is completed. In addition, RareGen management prepared certain forward-looking financial information which our management adjusted to develop its own forecasts for the RareGen business on a stand-alone basis.

This forward-looking financial information for our company and RareGen prepared by our management was not prepared with a view toward compliance with published guidelines of the SEC or the guidelines established by the American Institute of Certified Public Accountants for preparation or presentation of prospective financial information.

The forward-looking financial information included in this document has been prepared by, and is the responsibility of, our management. PricewaterhouseCoopers LLP has not audited, reviewed, examined, compiled nor applied agreed-upon procedures with respect to the accompanying forward-looking financial information and, accordingly, PricewaterhouseCoopers LLP does not express an opinion or any other form of assurance with respect thereto. The PricewaterhouseCoopers LLP report incorporated by reference relates to our previously issued financial statements. It does not extend to the forward-looking financial information and should not be read to do so.

The forward-looking financial information prepared by our management and RareGen management is subjective in many respects and thus subject to interpretation. While presented with numeric specificity, the forward looking financial information reflects numerous estimates and assumptions made by our management or RareGen management, as the case may be, with respect to industry performance and competition, regulatory approvals and the timing thereof, and general business, economic and market conditions, all of which are difficult to predict and many of which are beyond the control of our management and RareGen management.

The forward-looking financial information prepared by our management also reflects assumptions by our management as to certain business decisions that are subject to change. Accordingly, there can be no assurance that the forward-looking results are indicative of the future performance of our company, RareGen or HoldCo or that actual results will not differ materially from those presented. Inclusion of the forward-looking financial information in this proxy statement/prospectus should not be regarded as a representation by us, RareGen or Jefferies or any other person that the results contained in the forward-looking financial

information will be achieved. The forward-looking financial information covers multiple years. Such information, by its nature, becomes less predictive with each successive year. Readers of this proxy statement/prospectus are cautioned that the forward-looking financial information should not be construed as financial guidance and should not be relied on as such or for any other reason. The forward-looking financial information is not included in this proxy statement/prospectus in order to induce any stockholder to vote in favor of any matter or to purchase securities of any person.

The forward-looking financial information has not been updated since the date of its preparation. We do not intend, nor do we assume any obligation, to update or otherwise revise the forward-looking financial information as a result of circumstances existing since our preparation, to reflect the occurrence of unanticipated events or otherwise, even in the event that any or all of the underlying assumptions are shown to be in error. Furthermore, we do not intend to update or revise the forward-looking financial information in this proxy statement/prospectus to reflect changes in general economic or industry conditions.

Liquidia Technologies Forward-Looking Information

In connection with the process leading up to the Merger Agreement, our management prepared estimated financial forecasts under certain scenarios for our company on a stand-alone, pre-transaction basis. These forecasts are included in this proxy statement/prospectus because they were provided to our board of directors in connection with its consideration of the Merger Transaction and to Jefferies for use in its financial analysis.

The financial forecasts for our clinical-stage, pre-revenue company at this time are primarily comprised of two components: (a) the successful approval and timing of commercial launch of LIQ861 for use in World Health Organization (WHO) Group 1 (PAH), which is currently subject to a 30-month regulatory stay at the FDA pending resolution of a patent infringement suit; and (b) the estimated value of our platform, pipeline and PRINT® technology. With regard to LIQ861, our management prepared forecasts based on three probability-weighted scenarios to account for a range of uncertainty in approval and timing of launch. The three scenarios included: (i) an FDA approval and launch of LIQ861 in the fourth quarter of 2021; (ii) an FDA approval and launch of LIQ861 in the fourth quarter of 2022; and (iii) an FDA decision not to approve LIQ861. The launch timing in scenarios (i) and (ii) are estimates based on the projected time frames to resolve patent litigation as calculated by (x) a successful result from our two petitions for inter partes review with the Patent Trial and Appeal Board initiated in March 2020, and (y) the full-length of the 30-month regulatory stay of approval. The estimates in these three scenarios, along with an estimated value of $40 million for our pipeline and technology, were provided to Jefferies for use in its financial analysis.

The estimates and assumptions underlying the our forecasts are inherently uncertain and are subject to a wide variety of significant business, economic, regulatory and competitive risks and uncertainties that could cause actual results to differ materially from those contained therein, including, the matters described in the sections entitled “Risk Factors” beginning on page 36 and “Forward-Looking Statements” beginning on page 87, in our Annual Report on Form 10-K filed with the SEC on March 16, 2020 and in our Quarterly Report on Form 10-Q filed with the SEC on May 11, 2020.

In addition, we provided Jefferies for use in its financial analysis certain projected information for our company prepared by our management, which Jefferies used to calculate our estimated unlevered free cash flows for the years fiscal 2020 through 2037 under the two launch scenarios described above: (i) an FDA approval and launch of LIQ861 in the fourth quarter of 2021, and (ii) an FDA approval and launch of LIQ861 in the fourth quarter of 2022. Jefferies calculated our company’s estimated unlevered free cash flows under each scenario by subtracting capital expenditures and changes in net working capital from net operating income (after tax), and adding back amortization and depreciation expense. All of the data that Jefferies used to calculate the unlevered free cash flows for our company were provided by our management and approved by our company for use by Jefferies.

The results of these calculations of unlevered free cash flows for our company for the fiscal years 2020 through 2037 using our company forecasts for each of the two scenarios is set forth below:

Using the RareGen forecasts, our management prepared forecasts for RareGen on a stand-alone, pre-transaction basis for the fiscal years 2020 through 2024. Our RareGen forecasts assumed a smaller branded market size and lower generic penetration than the RareGen management forecasts, and assumed discounting to branded products to occur earlier than the RareGen management forecasts. Our RareGen forecasts are included in this proxy statement/prospectus because we and RareGen provided the 2020-2024 forecasts for RareGen to our board of directors in connection with its consideration of the Merger Transaction and to Jefferies for use in its financial analysis.

In addition, we provided Jefferies for use in its financial analysis certain projected information for RareGen prepared by our management, which Jefferies used to calculate RareGen’s estimated unlevered free cash flows for the fiscal years 2020 through 2024. We also instructed Jefferies to perform an illustrative discounted cash flow analysis of RareGen for the years 2020 through 2024 using the forecasts for RareGen provided by RareGen management. Jefferies calculated RareGen’s estimated unlevered free cash flows by subtracting capital expenditures from operating income and adding back interest, tax expense, amortization (excluding amortization of acquired intangibles), and depreciation, and adjusting for changes in working

capital. All of the data that Jefferies used to calculate the unlevered free cash flows for RareGen were provided by our management and approved by our company for use by Jefferies.

The results of these calculations of unlevered free cash flows for RareGen for the fiscal years 2020 through 2024 using our RareGen forecasts and using RareGen management forecasts is set forth below:

Unlevered Free Cash Flows ($ in millions)	2020			2021			2022			2023			2024

Our RareGen Forecasts		$	4.4		$	4.2		$	2.2		$	5.4		$	5.7

The differences between RareGen management forecasts and our RareGen forecasts were primarily as a result of different assumptions related to generic erosion of the branded product market and price discount assumptions over time.

The estimates and assumptions underlying the 2020-2024 forecasts for RareGen are inherently uncertain and are subject to a wide variety of significant business, economic, regulatory and competitive risks and uncertainties that could cause actual results to differ materially from those contained therein, including, the matters described in the sections entitled “Risk Factors” beginning on page 36 and “Forward-Looking Statements” beginning on page 87.

Estimated Synergies

Our management prepared estimates of annual synergies expected to be realized following the closing of the Merger Transaction, which are referred to in this section as the “Estimated Synergies.” The Estimated Synergies are not reflected in our company forecasts or our RareGen forecasts. These Estimated Synergies include the following: (i) incremental revenue from LIQ861 net sales of $11 to $16 million in the first five years after approval of LIQ861 as a result of having an existing, experienced sales force deployed in the field prior to the LIQ861 launch; and (ii) cumulative run-rate cost savings to our company of $5.3 million post-approval of LIQ861, accounting for the existing sales force expenses attributed to RareGen. The Estimated Synergies were provided by our management to Jefferies and approved by us for use by Jefferies in its financial analysis. This information should be read in light of the risks described under “Risk Factors” beginning on page 36, “Forward-Looking Statements” beginning on page 87, in our Annual Report on Form 10-K filed with the SEC on March 16, 2020 and in our Quarterly Report on Form 10-Q filed with the SEC on May 11, 2020.

Structure of the Merger Transaction

Pursuant to the terms of the Merger Agreement, a direct wholly owned subsidiary of HoldCo, RareGen Merger Sub, will merge with and into RareGen such that RareGen will become a subsidiary of HoldCo. This merger is referred to as the RareGen Merger. Immediately following the RareGen Merger, a direct wholly owned subsidiary of HoldCo, Liquidia Merger Sub, will merge with and into us such that we will also become a subsidiary of HoldCo. This merger is referred to as the Liquidia Merger.

Effective Time of the Merger Transaction

The closing of the Liquidia Merger and RareGen Merger, and consequently the Merger Transaction as a whole, contemplated by the Merger Agreement, will occur remotely via the exchange of documents and signatures no later than the second business day after the last of the conditions to the Merger Transaction have been satisfied or, if permissible, waived, unless another date is agreed to in writing by us and RareGen. As early as practicable on the closing date, we and RareGen will file certificates of merger with the Secretary of State of the State of Delaware to effect the Liquidia Merger and the RareGen Merger. The mergers will become effective upon the filing of these certificates or at such other time as we and RareGen agree in writing and specify in the certificates of merger. We and RareGen currently expect that the closing of the Merger Transaction will take place late in the third calendar quarter of 2020 or early in the fourth calendar quarter of 2020. However, because the Merger Transaction is subject to stockholder approval and other customary conditions, we and RareGen cannot predict exactly when the closing will occur.

TABLE OF CONTENTS

The Merger Consideration and Conversion of Securities

General

Upon the closing of the Merger Transaction, (i) each share of our common stock, whether certificated or held in book-entry form, will automatically convert into one share of HoldCo common stock, (ii) each option or warrant to purchase our common stock will automatically convert into the right to receive one share of HoldCo common stock for each share of our common stock subject to the option or warrant, and the exercise price per share will remain the same as the exercise price underlying such option or warrant, and (iii) each restricted stock unit to acquire our common stock will automatically convert into the right to receive one share of HoldCo common stock for each share of our common stock subject to such restricted stock unit grant.

Upon consummation of the Merger Transaction, HoldCo will issue to RareGen’s members an aggregate of 6,166,666 shares of HoldCo common stock, including 616,666 shares of HoldCo common stock, referred to in the Merger Agreement as “Holdback Shares”, which are being withheld to satisfy potential indemnification obligations of RareGen members. In addition, HoldCo will issue up to 2,708,333 shares of HoldCo common stock in 2022, which are referred to in the Merger Agreement as “Net Sales Earnout Shares”, if RareGen achieves at least $32.9 million of 2021 net sales (as calculated by Sandoz net sales), with the number of Net Sales Earnout Shares to be issued to depend upon the actual amount of the 2021 net sales. Furthermore, RareGen members have a contingent right to receive, on a pro rata basis, any RareGen cash at closing in excess of $1 million. With respect to the Net Sales Earnout Shares which may be issued to RareGen members, the actual amount of shares of HoldCo common stock which RareGen members are entitled to receive on a pro rata basis is subject to a sliding scale if 2021 net sales falls between $32.9 million and $61.1+ million such that HoldCo shall issue to RareGen members, on a pro rata basis, between 1,458,333 Net Sales Earnout Shares and 2,708,333 Net Sales Earnout Shares of additional HoldCo shares. For the avoidance of doubt, if 2021 net sales is less than $32.9 million, then no Net Sales Earnout Shares shall be issued to RareGen members, and if RareGen’s 2021 net sales is greater than $61.1 million, then the maximum 2,708,333 shares of HoldCo common stock will be issued to RareGen’s members in the aggregate, on a pro rata basis.

The shares of HoldCo common stock issued to RareGen members on the closing date of the Merger Transaction will be subject to a six-month lock-up from the date of issuance as described under “The Merger Agreement — Agreements Entered Into in Connection with the Merger Agreement: Post-Closing Transfer Restrictions” on page 140.

RareGen Net Sales Earnout Shares Procedures

No later than 15 days after the receipt by HoldCo or RareGen post-closing of each quarterly report from Sandoz pursuant to the Promotion Agreement with respect to any calendar quarter ending on or prior to the last day of the January 1, 2021 — December 31, 2021 net sales earnout period, or any proposed amendment thereto, HoldCo shall send a copy of such quarterly report to the Members’ Representative. As soon as practicable, but, in any event, within 15 days after the delivery of a quarterly report, the Members’ Representative shall provide to HoldCo a written report indicating its agreement with, or specific itemized objections to, or any additional information it reasonably needs with respect to, Sandoz’s calculation of the net sales, or a Quarterly Objection Report. Within 15 days of the receipt by HoldCo of a Quarterly Objection Report, if any, the Members’ Representative and HoldCo shall reasonably cooperate to take such actions as may be available under the Promotion Agreement to object to Sandoz’s calculation of net sales and/or request additional information from Sandoz regarding such calculation, and thereafter, the Members’ Representative and HoldCo shall use good faith efforts to cause Sandoz to adjust its calculation of net sales for such period for all purposes under the Promotion Agreement (including in connection with any reconciliation thereof) as set forth in the Quarterly Objection Report. No later than the earlier of (i) 15 days after the completion of the final reconciliation for the 2021 calendar year and (ii) March 31, 2022, HoldCo shall prepare and deliver to the Members’ Representative a “Draft Net Sales Report”, as defined in the Merger Agreement, that sets forth (A) HoldCo’s good faith calculations of the 2021 net sales, (B) whether net sales of at least $32.9 million have been achieved and therefore, if all or any portion of the Net Sales Earnout Shares would be issued, and (C) the number of Net Sales Earnout Shares to be issued. The Draft Net Sales

110

TABLE OF CONTENTS

Report shall be prepared using the net sales information as reported to HoldCo or RareGen post-closing in accordance with the Promotion Agreement, subject to any adjustments mutually agreed upon by Sandoz, HoldCo and the Members’ Representative. Within 30 days after the delivery of a Draft Net Sales Report and any requested supporting documentation, the Members’ Representative shall provide to HoldCo a written report indicating its agreement with, or specific itemized objections to, HoldCo’s calculation of net sales for 2021, which is referred to in the Merger Agreement as the “Members’ Representative Net Sales Response”. Failure by the Members’ Representative to object to HoldCo’s calculation of 2021 net sales or, if earlier, the Members’ Representative’s affirmative agreement in writing to HoldCo’s calculations shall be deemed to be the Members’ Representative’s acceptance of the Draft Net Sales Report and that Draft Net Sales Report shall automatically and irrevocably be deemed a “Final Net Sales Report”, as defined in the Merger Agreement, except in the case of fraud. Within 15 days after receipt by HoldCo of the Members’ Representative’s Net Sales Response, if any, the Members’ Representative and HoldCo shall endeavor in good faith to agree on any matters in dispute. If HoldCo and the Members’ Representative are unable to agree on any remaining matters in dispute within such 15 day period referred to above, then, the matters in dispute will be submitted for resolution to an independent accounting firm, which shall within 30 days of such submission, acting as experts and not arbitrators, determine and issue a written report to the Members’ Representative and HoldCo upon such disputed items and such written report shall automatically and irrevocably be deemed the Final Net Sales Report, except in the case of fraud. If 2021 net sales of at least $32.9 million are achieved, then HoldCo shall issue shares of HoldCo common stock to the Exchange Agent, on behalf of each RareGen member, in the amount of the Net Sales Earnout Shares for distribution to the RareGen members according to their pro rata ownership of RareGen at the time of the Merger Transaction, subject to the terms set forth therein, within 30 days following the achievement of net sales of at least $32.9 million based upon the issuance of a Final Net Sales Report. Notwithstanding the foregoing, HoldCo shall be entitled to operate RareGen post-Merger Transaction and the promotion of the Product as it deems appropriate in its sole discretion. Further, (i) there is no assurance that any net sales earnout and net sales earnout issuance will be realized, in whole or in part; (ii) HoldCo owes no fiduciary duty to RareGen post-closing or the RareGen members with respect to the achievement of the net sales earnout; provided, however, that nothing shall excuse HoldCo from its obligation to adhere to good faith and/or fair dealing when determining whether or not 2021 net sales of at least $32.9 million were achieved; provided,¸further, that HoldCo shall cause RareGen to use commercially reasonable efforts to achieve 2021 net sales of at least $32.9 million and not act in a manner that intentionally reduces 2021 net sales. “Net Sales Earnout Amount” is defined in the Merger Agreement as 2021 net sales as determined pursuant to the Promotion Agreement, divided by 3.76, up to a maximum Net Sales Earnout Amount of $16,250,000.

In the event HoldCo enters into a “Sale Transaction”, as defined in the Merger Agreement, at any time prior to December 31, 2021, then the successors and assigns of HoldCo shall assume HoldCo’s obligations relating to the Net Sales Earnout Amount; provided, however, that the RareGen members will be entitled to receive, in lieu of the Net Sales Earnout Shares, the number and kind of securities and property that the RareGen members would have received with respect to the Net Sales Earnout Shares if such Net Sales Earnout Shares had been distributed immediately before the closing of such sale transaction.

Holdback Shares

The Holdback Shares shall be withheld from RareGen members at closing for the purpose of securing the indemnification obligations of RareGen to Liquidia Indemnitees. On March 31, 2022, the RareGen members will be entitled to their respective pro rata percentage of the Holdback Shares, subject to reduction as set forth in the immediately following sentence, together with any stock dividends with respect to the Holdback Shares. The Holdback Shares may be reduced by: (i) the portion of the Holdback Shares, if any, used to satisfy the obligations of the RareGen members to the Liquidia Indemnitees in accordance with Article 7 of the Merger Agreement; and (ii) the portion of the Holdback Shares, if any, to the extent reasonably necessary to serve as security for any unresolved or unsatisfied claims for losses incurred by an indemnified party, which are referred to in the Merger Agreement as the Reserve Shares. The Holdback Shares remaining after giving effect to the reductions set forth in clauses (i) and (ii) in the immediately preceding sentence are referred to in the Merger Agreement as the “Remaining Holdback Shares.” The Remaining Holdback Shares shall be disbursed to the Exchange Agent, for the benefit of the RareGen members, on March 31, 2022, or the Holdback Shares Release Date, and the Reserve Shares shall be disbursed to the Exchange Agent, for the benefit of the RareGen members upon the final resolution of any unresolved

111

TABLE OF CONTENTS

claim to which such Reserve Shares were subject. For more information about the indemnification obligations of RareGen members, see “The Merger Agreement — Indemnification” beginning on page 130.

HoldCo Governing Documents

Upon the closing of the Merger Transaction, the Certificate of Incorporation and Bylaws of HoldCo shall remain the Certificate of Incorporation and Bylaws of HoldCo.

Procedures for Payment of Merger Consideration

Promptly after the effective time of the Merger Transaction, HoldCo will deposit with the Exchange Agent shares of HoldCo common stock issuable in exchange for outstanding RareGen common units.

RareGen members should not transfer their holdings for exchange unless and until they receive the transmittal instructions and a letter of transmittal from the Exchange Agent.

Promptly after the effective time of the Merger Transaction, the Exchange Agent will mail to all RareGen members a letter of transmittal and instructions for use to effect the transfer of their common units in exchange for HoldCo common stock and any dividends or distributions with respect thereto. Upon the transfer of any RareGen common units for cancellation, to the Exchange Agent, as applicable, along with a completed and properly executed letter of transmittal and any other required documents, RareGen units will be cancelled and the RareGen member will receive a number of whole shares of HoldCo common stock, and any dividends or other distributions, to which such holder is entitled. No fractional shares of HoldCo common stock will be issued and RareGen members are not entitled to cash in lieu of such fractional shares. In lieu of any such fractional share that a RareGen member would otherwise be entitled, the number of shares of HoldCo common stock to be issued to a RareGen member shall be rounded down to the nearest whole share.

RareGen members are not entitled to receive any dividends or other distributions declared or made with respect to their shares of HoldCo common stock with a Record Date after the effective time of the Merger Transaction until they have transferred their RareGen common units to the Exchange Agent for cancellation. If there is any dividend or other distribution on HoldCo common stock with a Record Date after the effective time of the Merger Transaction and a payment date prior to the date RareGen common units are transferred, the transferring holder will receive any such dividend or other distribution with respect to the whole shares of HoldCo common stock issued after the units are transferred. If there is any dividend or other distribution on HoldCo common stock with a Record Date after the effective time of the Merger Transaction and a payment date after RareGen common units are transferred, the transferring holder will receive any such dividend or other distribution with respect to the whole shares of HoldCo common stock received on the payment date, without interest.

HoldCo, the Exchange Agent and the surviving corporations are entitled to deduct and withhold from the merger consideration otherwise payable such amounts as are required by applicable law.

No Fractional Shares

No certificates or scrip representing fractional shares of HoldCo common stock shall be issued upon the exchange of RareGen units, no dividend or distribution with respect to HoldCo common stock shall be payable on or with respect to any fractional share and such fractional share interests shall not entitle the owner thereof to any rights of a stockholder of HoldCo.

Transfers of Ownership and Lost Stock Certificates

Following completion of the Merger Transaction, all shares of our common stock outstanding immediately prior to the effective time of the Merger Transaction shall automatically be cancelled, and all of our stockholders shall cease to have any rights as stockholders of our company. No further transfers of shares of our common stock or RareGen common units shall be made on the stock or unit transfer books, as applicable, after the effective time of the Merger Transaction.

112

TABLE OF CONTENTS

Following completion of the Merger Transaction, all RareGen common units outstanding immediately prior to the effective time of the Merger Transaction shall automatically be cancelled, and all holders of RareGen common units shall cease to have any rights as holders of such securities. No further transfers of RareGen common units shall be made on the unit transfer books after the effective time of the Merger Transaction. If, after such time, any RareGen common units are presented to the Exchange Agent, HoldCo or RareGen, they will be cancelled and exchanged for the merger consideration.

Unclaimed Amounts

Any portion of the merger consideration deposited with the Exchange Agent that remains undistributed to RareGen members 12 months after the effective time of the Merger Transaction shall be delivered to HoldCo upon demand, and any RareGen members who have not transferred their common units for cancellation by then can only look to HoldCo for satisfaction of their claims for the merger consideration.

Treatment of Stock Options, Warrants and Restricted Stock Units

After the effective time of the Merger Transaction, HoldCo will assume each outstanding option to purchase shares of our common stock under the Liquidia Technologies, Inc. Stock Option Plan, as amended, the Liquidia Technologies, Inc. 2016 Equity Compensation Plan, as amended, and the Liquidia Technologies, Inc. 2018 Long-Term Incentive Plan, which we collectively refer to herein as the Liquidia Equity Plans. Each assumed option will continue to have, and be subject to, the same terms and conditions set forth in the applicable foregoing plans, including but not limited to the exercise price, except that each assumed option will be exercisable for that number of whole shares of HoldCo common stock. The conversion of any Liquidia Technologies options which are incentive stock options within the meaning of Section 422 of the Code, into options to purchase HoldCo common stock is intended to be made so as not to constitute a “modification” of such Liquidia Technologies options within the meaning of Section 424 of the Code. Continuous employment with us or our subsidiaries shall be credited to the optionee for purposes of determining the vesting of all assumed Liquidia Technologies options after the effective time of the Merger Transaction. Each assumed Liquidia Technologies option, as of the effective time of the Merger Transaction, will be vested as to the same percentage of the total number of shares subject to the option as it was vested immediately prior to the effective time of the Merger Transaction.

At the effective time of the Merger Transaction, HoldCo will assume each issued and outstanding warrant and other right to acquire our common stock, whether or not exercisable at the effective time of the Merger Transaction, in accordance with the terms of such warrants and other rights. The number of HoldCo shares of common stock underlying the warrant of any such HoldCo warrant will equal the number of shares of our common stock underlying the Liquidia Technologies warrant and the exercise price of such HoldCo warrant will equal the exercise price of such Liquidia Technologies warrant.

Additionally, at the effective time of the Merger Transaction, HoldCo will assume each issued and outstanding restricted stock unit to acquire our common stock. The number of HoldCo shares of common stock underlying the restricted stock unit will equal the number of shares of our common stock underlying the Liquidia Technologies restricted stock unit. Continuous employment with us shall be credited to the holders of our restricted stock units for purposes of determining the vesting of all assumed Liquidia Technologies restricted stock units after the effective time of the Merger Transaction.

Outstanding options and restricted stock units to acquire our common stock will be assumed by HoldCo.

As soon as reasonably practicable after the effective time of the Merger Transaction, but in any event within 20 days after the effective time of the Merger Transaction, HoldCo will file one or more registration statements on Form S-8 for the shares of its stock issuable with respect to our stock options and restricted stock units assumed in the Merger Transaction.

Material U.S. Federal Income Tax Consequences

The following discussion sets forth the intended material U.S. federal income tax consequences of the Merger Transaction to our stockholders who exchange their shares of our common stock in the Merger Transaction. This discussion is based on the Code, and the related Treasury regulations, administrative interpretations and court decisions, all of which are subject to change, possibly with retroactive effect. Any change could affect the accuracy of the statements and the conclusions discussed below and the tax consequences of the Merger Transaction. This discussion applies only to our stockholders that hold their shares of our common stock, and will hold the shares of HoldCo common stock received in exchange for such shares, as capital assets within the meaning of Section 1221 of the Code.

If a partnership or any other entity taxed as a partnership for U.S. federal income tax purposes is a beneficial owner of shares of our common stock, the treatment of a partner in the partnership or other entity taxed as a partnership will generally depend upon the status of the equity owner of such partnership or entity taxed as a partnership and the activities of the partnership or other entity taxed as a partnership. If you are a partner (or other owner) of a partnership or other pass-through entity that is a beneficial owner of our common stock, you should consult your tax advisor regarding the tax consequences of the Merger Transaction. The tax consequences to a beneficial owner who or that is not described in this paragraph may differ substantially from the tax consequences discussed below.

This discussion does not address all U.S. federal income tax consequences of the Merger Transaction that may be relevant to particular stockholders, including, without limitation, the following:

•

stockholders who are not citizens or residents of the United States;

•

dealers or traders in securities;

•

regulated investment companies and REITs;

•

stockholders who exercise appraisal rights in connection with the Merger Transaction;

•

banks and other financial institutions;

•

insurance companies;

•

tax-exempt organizations;

•

individual retirement accounts;

•

holders of shares of our common stock as part of a position in a “straddle” or as part of a “hedging” or “conversion” transaction;

•

stockholders who have entered into a constructive sale under the Code;

114

TABLE OF CONTENTS

•

stockholders who have a “functional currency” other than the U.S. dollar;

•

stockholders who are foreign persons;

•

stockholders who are controlled foreign corporations, passive foreign investment companies or U.S. expatriates;

•

stockholders who own their shares indirectly through partnerships, S-corporations, trusts or other entities that may be subject to special treatment; and

•

stockholders who acquired their shares of our common stock through stock option or employee stock purchase programs or otherwise as compensation.

This discussion does not discuss the tax consequences of transactions effectuated prior or subsequent to, or concurrently with, the Merger Transaction (whether or not any such transactions are undertaken in connection with the Merger Transaction), including, without limitation, any transaction in which shares of our common stock are acquired or shares of HoldCo common stock are disposed of. This discussion also does not discuss the tax consequences of the Merger Transaction to holders of RareGen common units, holders of options or warrants to purchase our common stock or restricted stock units to acquire our common stock or holders of our promissory notes, if any. In addition, this discussion does not address any consequences arising under the laws of any state, local or foreign jurisdiction, any estate or gift tax considerations, any installment sale or open transaction disposition considerations, the application of the alternative minimum tax or the Medicare contribution surtax on net investment income, or any U.S. federal non-income taxes.

OUR STOCKHOLDERS ARE URGED TO CONSULT THEIR OWN TAX ADVISORS AS TO SPECIFIC TAX CONSEQUENCES TO THEM OF THE MERGER TRANSACTION, INCLUDING THE APPLICABILITY AND EFFECT OF ANY STATE, LOCAL OR FOREIGN TAX LAWS AND OF CHANGES IN APPLICABLE TAX LAWS.

Based upon customary covenants, assumptions and representations as to factual matters described below, all of which must continue to be true and accurate as of the effective time of the Merger Transaction, (i) the Merger Transaction is intended to qualify as an exchange described in Section 351 of the Code and (ii) accordingly, the tax consequences of the Merger Transaction are as set forth below. This discussion of material U.S. federal income tax consequences of the Merger Transaction and of the ownership and disposition of our common stock received in the Merger Transaction is not binding on the Internal Revenue Service, or the IRS. No assurance is given that the IRS would not assert, or that a court would not sustain, a position contrary to any described herein.

Stockholders Exchanging Shares of our Common Stock Solely for HoldCo Common Stock

A holder of our common stock who exchanges all of his, her or its shares of our common stock and receives only shares of HoldCo common stock in the Merger Transaction is not intended to recognize gain or loss for U.S. federal income tax purposes. Each holder’s aggregate tax basis in the HoldCo capital stock received in the Merger Transaction will be the same as his or her aggregate tax basis in our common stock exchanged in the Merger Transaction. The holding period of the HoldCo common stock received in the Merger Transaction by a holder of our common stock will include the holding period of our common stock that he, she or it exchanged in the Merger Transaction. If a holder of our common stock has differing tax bases and/or holding periods in respect of the stockholder’s shares of our common stock, the stockholder should consult with a tax advisor in order to identify the tax bases and/or holding periods of the particular shares of HoldCo common stock that the stockholder receives.

HoldCo and Liquidia Technologies

None of HoldCo or we will recognize gain or loss as a result of the Merger Transaction, the Liquidia Merger or the RareGen Merger.

Reporting

Each of our stockholders will be required to attach a statement to his, her or its U.S. federal income tax return for the year of the closing that contains the information listed in Treasury

115

TABLE OF CONTENTS

Regulations Section 1.351-3. Such statement must include the stockholder’s tax basis in our common stock and a description of the HoldCo common stock received.

THE PRECEDING DISCUSSION DOES NOT PURPORT TO BE A COMPLETE ANALYSIS OR DISCUSSION OF ALL OF THE POTENTIAL TAX CONSEQUENCES OF THE MERGER TRANSACTION. OUR STOCKHOLDERS SHOULD CONSULT THEIR TAX ADVISORS REGARDING THE SPECIFIC TAX CONSEQUENCES TO THEM OF THE MERGER TRANSACTION, INCLUDING TAX RETURN REPORTING REQUIREMENTS, AND THE APPLICABILITY AND EFFECT OF U.S. FEDERAL, STATE, LOCAL, NON-U.S. AND OTHER APPLICABLE TAX LAWS IN LIGHT OF THEIR PARTICULAR CIRCUMSTANCES.

Other Approvals

If any additional governmental approvals or actions are required, we and RareGen intend to obtain them. We and RareGen cannot assure you, however, that we and RareGen will be able to obtain any approvals or actions.

Accounting Treatment

The Merger Transaction will be accounted for using the acquisition method of accounting with Liquidia Technologies considered the acquirer of RareGen. In identifying our company as the acquiring entity, the companies took into account the relative outstanding share ownership, the composition of the governing body of the combined entity, HoldCo, and the designation of certain senior management positions. As a result, the historical financial statements of our company will become the historical financial statements of HoldCo. We will record assets acquired, including identifiable intangible assets, and liabilities assumed from RareGen at their respective fair values at the date of completion of the Merger Transaction. Financial statements of HoldCo after the effective time of the Merger Transaction will reflect such fair values and will not be restated retroactively to reflect the historical financial position or results of operations of RareGen. Any excess of the purchase price over the net fair value of such assets and liabilities will be recorded as goodwill. The results of operations of RareGen will be included in the results of operations of HoldCo beginning on the effective date of the Merger Transaction. See the section entitled “Unaudited Pro Forma Condensed Combined Financial Statements of HoldCo” beginning on page 77 for more information.

Interests of Certain Directors, Officers and Affiliates of Liquidia and RareGen

When considering the recommendation of our board of directors and its transaction committee with respect to the Merger Agreement and the Merger Transaction contemplated by the Merger Agreement, our stockholders should be aware that certain members of the respective boards of directors and executive officers of our company and RareGen have interests in the Merger Transaction contemplated by the Merger Agreement that may be different from, or in addition to, the interests of our stockholders, generally. Our board of directors took these interests into account in determining the fairness of the Merger Transaction to our stockholders when making its decision to approve and declare the advisability of the Merger Agreement.

Indemnification; Directors’ and Officers’ Insurance

Pursuant to the Merger Agreement, HoldCo will, and will cause us and RareGen to, indemnify the directors and executive officers of our company and RareGen, as described in the section entitled “The Merger Agreement — Indemnification and Insurance” on page 135.

Employment and Compensation

Roger A. Jeffs, Ph.D. and Paul B. Manning, current directors of RareGen, will become Class I and Class III directors of HoldCo, respectively, after the Merger Transaction and will be entitled to receive compensation as directors of HoldCo. Mr. Manning is the manager and sole beneficial owner of PBM Capital Finance, which currently owns 70.65% of RareGen’s common units. Dr. Jeffs is the manager of Serendipity BioPharma LLC, which currently owns 25.00% of RareGen’s common units. Dr. Jeffs and Mr. Manning currently own 18,595 and 1,018,466 shares, respectively, of our common stock through various entities which they control. Contingent and effective upon the closing of the Merger Transaction, the HoldCo board of

116

TABLE OF CONTENTS

directors will increase the increased the authorized number of directors from eight to nine and a current director of HoldCo is expected to resign.

The current officers of Liquidia Technologies will retain their same positions and salaries at HoldCo as those currently held at Liquidia Technologies. Scott Moomaw, RareGen’s Chief Operating Officer, will become HoldCo’s Senior Vice President, Commercial after the Merger Transaction. Mr. Moomaw is expected to become Senior Vice President, Commercial of HoldCo effective immediately following the Merger Transaction and will receive, among other benefits, an annual salary and a discretionary annual cash bonus commensurate with our other senior executive officers on Mr. Moomaw’s level, and an incentive stock option grant to purchase shares of HoldCo common stock on his first day of employment, vesting over a four-year period with an exercise price equal to the then-fair market value of HoldCo common stock. Additionally, certain of the other employees of RareGen will become employees of HoldCo after the Merger Transaction. Damian deGoa, RareGen’s Chief Executive Officer, will resign effective as of the closing of the Merger Transaction.

Dr. Ralph Snyderman, a current Class I director of our company and HoldCo, will resign as a director of our company and HoldCo effective upon the Merger Transaction. Therefore, following completion of the Merger Transaction, the directors of HoldCo will be Dr. Stephen Bloch, Neal F. Fowler, Katherine Rielly-Gauvin, Dr. Joanna Horobin, Roger A. Jeffs, Ph.D., Arthur Kirsch, Paul B. Manning, Dr. Seth Rudnick and Raman Singh. Each director of HoldCo will be entitled to receive compensation as directors of HoldCo, which compensation will be identical to what our directors currently receive for serving as directors of our company. See the section entitled “Directors and Officers of HoldCo Following Completion of the Merger Transaction: Director Compensation” beginning on page 150 for a description of the compensation to be received by HoldCo’s directors.

In connection with the Merger Transaction, on March 9, 2020, our board of directors established a transaction committee comprised of Dr. Stephen Bloch, Neal F. Fowler, Dr. Joanna Horobin, Arthur Kirsch and Dr. Seth Rudnick, with Mr. Kirsch as Chairman. The transaction committee has the authority to, among other things, negotiate the definitive transaction documentation relating to the Merger Agreement subject to the approval of the full board of directors and our stockholders. In recognition of their efforts, Mr. Kirsch will receive $10,000 as compensation for serving as Chairman of the transaction committee and Drs. Bloch, Horobin and Rudnick and Mr. Fowler will each receive $5,000 for their service as members of the transaction committee.

Listing of Shares of HoldCo Common Stock; Delisting and Deregistration of Shares of Liquidia Technologies Common Stock

It is a condition to the completion of the Merger Transaction that the shares of HoldCo common stock to be issued in the Merger Transaction be approved for listing on the Nasdaq Capital Market, subject to official notice of issuance.

If the Merger Transaction is completed, shares of our common stock will no longer be listed on the Nasdaq Capital Market and will be deregistered under the Exchange Act, and we will no longer file periodic reports with the SEC. Shares of HoldCo common stock will, however, be registered under the Exchange

117

TABLE OF CONTENTS

Act and listed on the Nasdaq Capital Market, and HoldCo will file periodic reports with the SEC as our reporting issuer successor.

Appraisal Rights

Appraisal rights are not available in all circumstances, and exceptions to these rights are provided under the DGCL. Section 262 of the DGCL provides that stockholders have the right, in some circumstances, to dissent from certain corporate actions and to instead demand payment of the fair value of their shares. Stockholders do not have appraisal rights with respect to shares of any class or series of stock if such shares of stock, or depositary receipts in respect thereof, are either (i) listed on a national securities exchange or (ii) held of record by more than 2,000 holders, unless the stockholders receive in exchange for their shares anything other than shares of stock of the surviving or resulting corporation (or depositary receipts in respect thereof), or of any other corporation that is publicly listed or held by more than 2,000 holders of record, cash in lieu of fractional shares or fractional depositary receipts described above or any combination of the foregoing. Therefore, because our common stock is listed on Nasdaq, and our stockholders will receive in the merger only shares of HoldCo common stock, which will be publicly listed on Nasdaq, holders of our common stock will not be entitled to appraisal rights in the merger with respect to their shares of our common stock.

Under the Delaware Limited Liability Company Act, appraisal rights do not exist except when those rights are specifically provided for in the company agreement or an agreement of merger. Because appraisal rights are not specifically provided for in the Merger Agreement or RareGen’s operating agreement, RareGen members also do not have appraisal rights in connection with the Merger Transaction.

Conduct of Liquidia’s and HoldCo’s Business Prior to Completion of the Merger Transaction

Except as set forth in our disclosure schedule, as may be required by the transactions contemplated by the Merger Agreement or any of the ancillary agreements, we and HoldCo may not, between the date of the Merger Agreement and the earlier of the termination of the Merger Agreement in accordance with its terms and the effective time of the Merger Transaction, directly or indirectly, do, or agree to do, any of the following without the prior written consent of RareGen, which consent will not be unreasonably conditioned, withheld or delayed: (A) adjust, split, combine or reclassify any of our or HoldCo’s capital stock or issue any shares of capital stock other than certain excluded securities, such as option and warrant exercises, or in connection with our July 2020 underwritten public offering of our common stock; (B) declare, set aside, set a Record Date for or pay any dividend or other distribution with respect to our common stock; (C) amend our or HoldCo’s certificate of incorporation or bylaws in any manner that would prohibit or hinder, impede or delay in any material respect the transactions contemplated by the Merger Agreement, the ancillary agreements or our July 2020 public offering; or (D) agree to, or make any commitment to, take or adopt any resolutions of our board of directors or similar governing body in support of, any of the actions prohibited by the Merger Agreement.

Meeting of Stockholders

We are obligated under the Merger Agreement to promptly and duly call, give notice of, and cause to be held, a special meeting of our stockholders for the purposes of adopting the Merger Agreement and approving the Liquidia Merger and any other transactions contemplated by the Merger Agreement, and to hold the meeting on or before the 60th day after the date on which the registration statement, of which this proxy statement/prospectus forms a part, becomes effective. Our board of directors shall recommend that our stockholders vote in favor of the adoption and approval of the Merger Agreement and the Liquidia Merger and shall not withdraw, modify or withhold such recommendation unless the following conditions are all met: (i) we and our representatives are materially complying with the no solicitation covenant; (ii) an unsolicited bona fide written alternative proposal is made to us by a third party and is not withdrawn; (iii) our board of directors, after consultation with our outside counsel, has determined in good faith, after giving effect to all of the adjustments which may be offered by RareGen pursuant to subclause (3) below, that the failure to make a change in recommendation would violate our board of directors’ fiduciary duties under applicable law; and (iv)(1) our board of directors has concluded in good faith, after giving effect to all of the adjustments which may be offered by RareGen pursuant to subclause (3) below, that such alternative proposal constitutes a superior proposal, (2) we have notified RareGen, at least five business days in advance, of our intention to make a change of recommendation in response to such superior proposal (including the identity of the party making such alternative proposal) and furnished to RareGen a written description of the material terms of the superior proposal or an unredacted copy of such written superior proposal, and (3) before making such a change in recommendation, we have, and have caused our financial and legal advisors to, during the period after our delivery of the notice referred to in subclause (2) above, negotiated with RareGen in good faith for a period of up to five business days (to the extent RareGen desires to negotiate) to make such adjustments in the terms and conditions of this Merger Agreement so that such alternative proposal ceases to constitute a superior proposal.

An “alternative proposal” means, other than our July 2020 underwritten public offering, any offer or proposal concerning any (A) merger, consolidation, business combination, or similar transaction involving us or our subsidiaries; (B) sale, lease, license or other disposition directly or indirectly by merger, consolidation, business combination, share exchange, joint venture, or otherwise of assets of our company representing 20% or more of the consolidated assets or revenues of our company; (C) issuance, sale, or other disposition of (including by way of merger, consolidation, business combination, share exchange, joint venture, or any similar transaction) securities (or options, rights or warrants to purchase, or securities convertible into or exchangeable for such securities) representing 20% or more of the voting power of our company; (D) transaction in which any person shall acquire beneficial ownership, or the right to acquire beneficial ownership or any group shall have been formed which beneficially owns or has the right to acquire beneficial ownership of 20% or more of the outstanding voting capital stock of our company, (E) transaction involving a sale, lease, license or other disposition directly or indirectly of any rights with respect to LIQ861 or any assets that are material to the manufacturing, distribution, marketing, promotion or sale thereof or (F) any combination of the foregoing (other than the Merger Transaction).

122

TABLE OF CONTENTS

A “superior proposal” means a bona fide alternative proposal (provided, that for this purpose, references to 20% in the definition of “alternative proposal” shall be deemed to be 50%) made by a third party which does not result in a breach by us of our “no solicitation” covenant in the Merger Agreement, and which, in the good faith judgment of our board of directors, taking into account, to the extent deemed appropriate by our board of directors, the various legal, financial and regulatory aspects of the proposal and the person making such proposal (i) if accepted, is reasonably likely to be consummated and (ii) if consummated would result in a transaction that is more favorable to our stockholders, from a financial point of view, than the transactions contemplated by the Merger Agreement (taking into account any changes to the terms of the Merger Agreement proposed by RareGen in response to such superior proposal or otherwise).

Except if the Merger Agreement is terminated in accordance with its terms, the above obligation to call and hold a meeting of our stockholders is not affected by the commencement, disclosure, announcement or submission of any acquisition proposal, or by any withdrawal, amendment or modification of either party’s board of directors’ recommendation in favor of the Merger Transaction and associated agreements.

Tax Matters

The amount of any taxes for a tax period beginning on or before the closing date and ending after the closing date, which is referred to in the Merger Agreement as the “Straddle Period”, allocable to the portion of the Straddle Period ending on the closing date shall (i) in the case of real and personal property taxes and franchise taxes not based on gross or net income, be equal to the amount of such taxes for the entire Straddle Period multiplied by a fraction, the numerator of which is the number of calendar days in the portion of the Straddle Period ending on the closing date and the denominator of which is the number of calendar days in the entire Straddle Period and, (ii) in the case of other taxes, be determined as if RareGen filed a separate tax return with respect to such taxes for the portion of the Straddle Period ending at the end of the day on the closing date using a “closing of the books methodology” based on the actual operations of RareGen, but assuming a similar interim closing of the books of any pass-through entity in which RareGen owns an interest and that the tax year of such pass-through entity ended on the closing date, and provided that, in determining the amount of such taxes, any exemptions, allowances or deductions that are calculated on a periodic basis (such as depreciation or amortization deductions) shall be pro-rated in the same manner as described in clause (i).

The Members’ Representative shall, at the expense of the RareGen members, timely prepare and file or cause to be prepared and filed all partnership income tax returns of RareGen for all taxable periods ending on or before the closing date that are due after the closing date. Any income tax deductions of RareGen arising in connection with the transactions contemplated by the Merger Agreement will be reflected in a partnership income tax return of RareGen for the pre-closing period to the extent permitted by applicable law. Prior to the filing of any such tax return, the Members’ Representative shall provide HoldCo with a final draft of such tax return at least 15 business days (after taking into account any applicable extensions) prior to the due date for such tax return, and shall consider in good faith any reasonable comments made by HoldCo. Such tax returns shall be prepared or completed in a manner consistent with prior practice of RareGen, except as otherwise required by law or otherwise agreed to in writing by HoldCo prior to the filing thereof.

For each pre-closing period, (i) RareGen shall, to the maximum extent permitted under applicable law, make a valid election under Section 6221(b) of the Code, which is referred to in the Merger Agreement as the “Audit Opt-Out Election”, on its applicable tax returns and (ii) to the extent an Audit Opt-Out Election is not permitted to be made pursuant to applicable law, RareGen shall timely elect pursuant to Section 6226 of the Code to have any partnership adjustments passed through to the RareGen members or their predecessors-in-interest during the taxable period subject to such adjustment.

After the closing date, the Members’ Representative shall have the exclusive right to represent the interests of RareGen and the RareGen members (at the RareGen members’ expense) in any tax contests that relate solely to partnership income taxes or partnership income tax returns of RareGen for any pre-closing period.

Promotion Agreement Payments

From and after the effective date of the Merger Transaction, if RareGen receives or collects any payments from Sandoz pursuant to the Promotion Agreement which are allocable to any period prior to closing, HoldCo shall cause RareGen to remit such funds to the Members’ Representative no later than April 15, 2021. For purposes of calculating the portion of any Sandoz payment that is allocable to a period prior to closing, the Sandoz payments received by RareGen and attributable to any given calendar month shall be allocated to the period prior to closing as follows: (A) with respect to Sandoz payments that are attributable to any calendar month that expires prior to the closing, 100% shall be allocated to the period prior to closing, and (B) with respect to Sandoz payments that are attributable to any calendar month that commenced prior to the closing but expires after the closing, a fraction of such Sandoz payments shall be

125

TABLE OF CONTENTS

allocated to the period prior to closing, the numerator of which is the number of calendar days in the portion of the calendar month ending on the closing date and the denominator of which is the number of calendar days in the entire calendar month.

No Solicitation

Under the terms of the Merger Agreement, we and RareGen each agreed not to take any action directly or indirectly, or authorize or permit any of our or its directors, officers, employees, agents or representatives, or to the extent under our or its control, our or its affiliates, to take any action to:

•

solicit, initiate or knowingly encourage, including by way of furnishing non-public information, or facilitate, to the extent that such party knew or should have known it was facilitating, any alternative proposal or RareGen acquisition proposal, as applicable;

•

enter into any agreement with respect to any alternative proposal or RareGen acquisition proposal, as applicable, or enter into any agreement, arrangement or understanding requiring it to abandon, terminate or fail to complete the Merger Transaction or any other transaction contemplated by the Merger Agreement or any ancillary agreement; or

•

We and RareGen further agreed that upon execution of the Merger Agreement, we and they would cease immediately and cause to be terminated any and all existing discussions or negotiations with any parties conducted up to the execution of the Merger Agreement with respect to an alternative proposal or RareGen acquisition proposal, as applicable. We and RareGen would also promptly request that all confidential information disclosed on our and their behalf in connection with any such discussions or negotiations be returned or destroyed. Furthermore, unless the Merger Agreement has been terminated in accordance with its terms, neither us nor RareGen shall, and we and they shall cause each of our and their respective subsidiaries and representatives not to, execute or enter into any letter of intent, agreement in principle, Merger Agreement, asset or stock purchase or share exchange agreement, option agreement or other contract related to any acquisition proposal or RareGen acquisition proposal, as applicable.

In addition, each of us and RareGen agreed to advise the other party as promptly as practicable, and in no event later than 24 hours, of receiving any inquiry relating to any potential alternative proposal or RareGen acquisition proposal, as applicable, and of the material terms of any proposal or inquiry, including the identity of the person and its affiliates making the proposal, or of any information requested from it or of any negotiations or discussions being sought to be initiated with it. We and RareGen must also furnish to the other party an unredacted copy of any such proposal or inquiry if it is in writing, or a written summary of any such proposal or inquiry if it is not in writing, and must keep the other party reasonably informed on a reasonably prompt basis with respect to any not-insignificant developments with respect to the proposal or inquiry.

If at any time after the date of the Merger Agreement and before the receipt of the affirmative vote of the holders of a majority of the outstanding shares of our common stock, we and/or our representatives receive a bona fide, unsolicited written acquisition proposal that did not result from a breach of the Merger Agreement, we and/or our representatives may engage in negotiations and discussions with, and furnish any information and other access (so long as all such information and access has previously been made available to RareGen or is made available to RareGen before or concurrently with the time such information or access is made available to such person) to, any person making such alternative proposal if, and only if, our board of directors determines in good faith, after consultation with our outside legal and financial advisors, that (i) such alternative proposal constitutes or is reasonably likely to become a superior proposal and (ii) the failure of our board of directors to furnish such information or access or enter into such discussions or negotiations would violate its fiduciary duties under applicable law; but before furnishing any such information, we shall have received from the person making such alternative proposal an executed confidentiality agreement with terms at least as restrictive in all material respects on such person as the

126

TABLE OF CONTENTS

confidentiality agreement between us and RareGen, which confidentiality agreement shall not prohibit us from complying with the terms of this “no solicitation” covenant.

Neither the RareGen board of directors nor any committee thereof shall (A) withdraw or modify, or propose publicly to withdraw or modify, in a manner adverse to us, the approval or recommendation of the RareGen board of directors or such committee of the adoption and approval of the RareGen Merger; (B) other than the RareGen Merger, approve or recommend, or propose publicly to approve or recommend, any RareGen acquisition proposal or (C) other than the RareGen Merger, cause RareGen to enter into any letter of intent, agreement in principle, acquisition agreement or other similar agreement related to any RareGen acquisition proposal.

A “RareGen acquisition proposal” means any offer or proposal concerning any:

•

merger, consolidation, business combination, or similar transaction involving RareGen;

•

sale, lease or other disposition directly or indirectly by merger, consolidation, business combination, equity exchange, joint venture, or otherwise of assets of RareGen representing 20% or more of the consolidated assets of RareGen;

•

issuance, sale or other disposition of, including by way of merger, consolidation, business combination, equity exchange, joint venture, or any similar transaction, securities, or options, rights or warrants to purchase, or securities convertible into or exchangeable for such securities, representing 20% or more of the voting power of RareGen;

•

a transaction in which any person acquires beneficial ownership, or the right to acquire beneficial ownership or any group has been formed which beneficially owns or has the right to acquire beneficial ownership of 20% or more of the outstanding voting equity of RareGen; or

•

any combination of the foregoing, other than the Merger Transaction contemplated by the Merger Agreement;

provided, however, that any offer or proposal, or agreement or transaction related to an offer or proposal, made or received after the termination of the Merger Agreement concerning any sale or issuance by RareGen of securities in one or more bona fide capital-raising transactions that do not result in any person or group obtaining the right to designate more than one-third of the members of the RareGen board of directors will not constitute an acquisition proposal.

RareGen Indemnification Limitations

Notwithstanding the foregoing, the RareGen members shall not have any liability under the Merger Agreement for any individual direct claim or third party claim if the losses associated therewith are less than $25,000, or the Claim Threshold, and any such losses below such claim threshold shall not be taken into account or aggregated for purposes of determining the applicability of the “Basket” (as defined below). Furthermore, RareGen members shall not be liable to the Liquidia Indemnitees for indemnification described above until the aggregate amount of all losses in respect of indemnification exceeds $200,000, which is referred to as the “Basket” in the Merger Agreement, in which event the RareGen members shall be required to pay or be liable for all such losses in excess of the Basket. Other than losses arising out of or resulting from any inaccuracy in or breach of any Fundamental Representation, indemnified taxes, transaction expenses or arising from fraud, the aggregate amount of all losses for which the RareGen members shall be liable pursuant to the foregoing section shall not exceed $3,700,000, which is referred to as the “Cap” in the Merger Agreement. The aggregate amount of all losses for which the RareGen members shall be liable with respect to the Fundamental Representations and indemnified taxes, when added to any other losses for which RareGen members may be liable thereunder, shall not exceed the value of the merger consideration actually paid to the RareGen members. The aggregate amount of all losses for which each RareGen member shall be liable (other than claims of fraud by such RareGen member) shall not exceed the lesser of (i) such RareGen member’s percentage share of such losses and (ii) the portion of the merger consideration actually received by the RareGen member.

Notwithstanding anything contained herein to the contrary, the Liquidia Indemnitees shall not be entitled to recover any losses (i) relating to any matter arising under one provision of the Merger Agreement

131

TABLE OF CONTENTS

to the extent that the Liquidia Indemnitees have already recovered the same losses with respect to such matter pursuant to Article 7 of the Merger Agreement, (ii) for any non-indemnified taxes, (iii) to the extent the matter giving rise to such loss had been reserved or provided for in the RareGen financial statements, (iv) that are contingent unless and until such contingent losses becomes actual losses (so long as the claim for such losses was timely submitted), (v) to the extent the Liquidia Indemnitees failed to mitigate such losses or (vi) for any otherwise indemnifiable losses arising out of any breach of any representation, warranty, covenant or agreement unless a claim therefore is asserted with specificity and in writing by such Liquidia Indemnitee timely in accordance with the Merger Agreement (failing which such claim shall be waived and extinguished). The amount of any loss for which indemnification is provided under the Merger Agreement shall be net of any amounts recovered or recoverable by Liquidia Indemnitees from any third party (including under insurance policies, if any) with respect to such loss. If a Liquidia Indemnitee recovers an amount from a third party in respect of losses that are the subject of indemnification hereunder after all or a portion of such losses have been paid by an indemnifying party pursuant to the Merger Agreement, then the Liquidia Indemnitees shall promptly remit to the indemnifying party the excess (if any) of (i) (A) the amount paid by the indemnifying party in respect of such losses plus (B) the amount received by the Liquidia Indemnitee from a third party in respect thereof over (ii) the full amount of the losses. In the event that a Liquidia Indemnitee has any rights against a third party with respect to any loss that results in a payment by an indemnifying party, such indemnifying party shall be subrogated to such rights to the extent of such payment.

Any losses arising out of or resulting from any inaccuracy in or breach of any representation or warranty shall be determined without regard to any materiality, Liquidia material adverse effect or other similar qualification contained in or otherwise applicable to such representation or warranty.

HoldCo Indemnification Limitations

Notwithstanding the foregoing, HoldCo shall not have any liability under the Merger Agreement for any individual direct claim or third party claim if the losses associated therewith are less than the Claim Threshold and any such losses below such Claim Threshold shall not be taken into account or aggregated for purposes of determining the applicability of the Basket. Additionally, HoldCo shall not be liable to the RareGen Member Indemnitees until the aggregate amount of all losses exceeds the Basket, in which event HoldCo shall be required to pay or be liable for all such losses in excess of the Basket. Other than losses arising out of or resulting from any inaccuracy in or breach of any HoldCo Fundamental Representation (as defined below), the aggregate amount of all losses for which HoldCo shall be liable thereunder shall not exceed the Cap. The aggregate amount of all losses arising out of or resulting from any inaccuracy in or breach of any HoldCo Fundamental Representation for which HoldCo shall be liable, when added to any other losses for which RareGen members may be liable thereunder, shall not exceed the value of the merger consideration actually paid to the RareGen members.

Indemnification Procedures

If any indemnified party receives notice of the assertion or commencement of any action made or brought by a third party against such indemnified party, which is referred to in the Merger Agreement as a “Third Party Claim,” the indemnified party shall give the indemnifying party prompt written notice thereof, but in any event not later than 30 calendar days after receipt of such notice of such Third Party Claim, which notice shall, among other things, describe the Third Party Claim in reasonable detail and include the estimated amount of the loss that has been or may be sustained by the indemnified party. The failure to give such prompt written notice shall not, however, relieve the indemnifying party of its indemnification obligations, except and only to the extent that the indemnifying party is adversely affected (including if the indemnifying party forfeits rights or defenses) by reason of such failure. The indemnifying party shall have the right to participate in, or by giving written notice to the indemnified party, to assume the defense of any Third Party Claim at the indemnifying party’s expense and by the indemnifying party’s own counsel, and the indemnified party shall cooperate in good faith in such defense; provided, that the indemnifying party shall not have the right to defend or direct the defense of any such Third Party Claim that seeks an injunction or other equitable relief against the indemnified parties. The indemnified party shall have the right to participate in the defense of any Third Party Claim with counsel selected by it subject to the indemnifying party’s right to control the defense thereof, with the fees and disbursements of such counsel being the expense

132

TABLE OF CONTENTS

of the indemnified party subject to certain limited exceptions. If the indemnifying party elects not to compromise or defend such Third Party Claim, fails to promptly notify the indemnified party in writing of its election to defend as provided in the Merger Agreement, or fails to diligently prosecute the defense of such Third Party Claim, the indemnified party may, subject to certain exceptions described below under “Settlement of Third Party Claims”, pay, compromise, defend such Third Party Claim and seek indemnification for any and all losses based upon, arising from or relating to such Third Party Claim. The Members’ Representative and HoldCo shall cooperate with each other in all reasonable respects in connection with the defense of any Third Party Claim.

Settlement of Third Party Claims

The indemnifying party shall not enter into a settlement of any Third Party Claim without the prior written consent of the indemnified party (which consent shall not be unreasonably withheld, conditioned or delayed), except as described herein. If a firm offer is made to settle a Third Party Claim without leading to liability or the creation of a financial or other obligation on the part of the indemnified party and provides, in customary form, for the unconditional release of each indemnified party from all liabilities and obligations in connection with such Third Party Claim and the indemnifying party desires to accept and agree to such offer, the indemnifying party shall give written notice to that effect to the indemnified party. If the indemnified party fails to consent to such firm offer within ten days after its receipt of such notice, the indemnified party may continue to contest or defend such Third Party Claim and in such event, the maximum liability of the indemnifying party as to such Third Party Claim shall not exceed the amount of such settlement offer. If the indemnified party fails to consent to such firm offer and also fails to assume defense of such Third Party Claim, the indemnifying party may settle the Third Party Claim upon the terms set forth in such firm offer to settle such Third Party Claim. If the indemnified party has assumed the defense pursuant to the section entitled “Indemnification Procedures” above, it shall not agree to any settlement without the written consent of the indemnifying party (which consent shall not be unreasonably withheld or delayed); provided, that such consent shall not be determinative as to whether any indemnified party is entitled to indemnification or the amount of losses relating to such matter.

Direct Claims

Any action by an indemnified party on account of a loss which does not result from a Third Party Claim, which is referred to in the Merger Agreement as a “Direct Claim”, shall be asserted by the indemnified party giving the indemnifying party reasonably prompt written notice thereof, but in any event not later than 30 days after the indemnified party becomes aware of such Direct Claim. The failure to give such prompt written notice shall not, however, relieve the indemnifying party of its indemnification obligations, except and only to the extent that the indemnifying party is adversely affected (including if the indemnifying party forfeits rights or defenses) by reason of such failure. Such notice by the indemnified party shall, among other things, describe the Direct Claim in reasonable detail, and shall indicate the estimated amount of the loss, if reasonably determinable, that has been or may be sustained by the indemnified party. The indemnifying party shall have 30 days after its receipt of such notice to respond in writing to such Direct Claim. If the indemnifying party does not so respond within such 30 day period, the indemnifying party shall be deemed to have rejected such claim, in which case the indemnified party shall be free to pursue such remedies as may be available to the indemnified party on the terms and subject to the provisions of the Merger Agreement.

Payments

(c) third, directly from the RareGen members by wire transfer of immediately available funds. Notwithstanding the foregoing, the Members’ Representative may elect, in its sole discretion, for any losses to be satisfied via wire transfer of immediately available funds in lieu of any reduction to the number of Holdback Shares, return of shares of HoldCo common stock or offset against the Net Sales Earnout Shares.

Any losses payable to a Liquidia Indemnitee pursuant to the indemnification provisions contained in the Merger Agreement shall be satisfied from the RareGen members, severally and not jointly, in proportion to their respective pro rata ownership of RareGen. Additionally, all indemnification payments made under the Merger Agreement shall be treated by the parties as an adjustment to the merger consideration for tax purposes, unless otherwise required by law.

•

by either us or RareGen if the Merger Transaction has not been completed by December 31, 2020, although such right to terminate the Merger Agreement shall not be available to any party whose failure to fulfill any obligation in the Merger Agreement has been the principal cause of, or resulted in, the failure of the Merger Transaction to occur on or before December 31, 2020;

•

by RareGen (provided RareGen is not then in material breach of any representation, warranty, covenant or other agreement contained therein) if we materially breach any representation or warranty set forth in the Merger Agreement or fails to perform any of our covenants set forth in the Merger Agreement and such breach or failure to perform is not cured by us within 30 days following receipt by us of RareGen’s written notice of such material breach or failure; or

•

by RareGen, if our board of directors shall have made a change in recommendation to our stockholders following the receipt of a superior proposal.

Termination Fee

In the event the Merger Agreement is terminated by (i) us on account of our acceptance of a superior proposal or (ii) RareGen, if our board of directors shall have made a change in recommendation to our stockholders following the receipt of a superior proposal, then, in the case of a termination by us pursuant to (i), we shall pay to RareGen by wire transfer a one-time termination fee equal to $7.5 million immediately before and as a condition to such termination, and in the case of a termination by RareGen pursuant to (ii), within two business days after the date of such termination.

The obligations under the Merger Agreement shall not be terminated or modified in such a manner as to adversely affect any indemnitee (or such indemnitee’s heirs, successors or assigns) to whom this provision of the Merger Agreement applies without the consent of such affected indemnitee (or such indemnitee’s heir, successor or assign), it being expressly agreed that the indemnitees (and such indemnitees’ heirs, successors and assigns) to whom this provision of the Merger Agreement applies shall be third-party beneficiaries of this provision.

Amendment and Waiver

The Merger Agreement may be amended in writing by the parties by action of their respective boards of directors at any time prior to the effective time of the Merger Transaction; provided that after obtaining our stockholders’ approval of the Merger Transaction, no amendment, which by any applicable law or rule requires further approval of such stockholders, shall be made without obtaining such further approval.

Pursuant to the Support Agreements, the Supporting Stockholders have agreed to, among other things, to the extent permitted by applicable law, rule or regulation, vote all of our common stock owned by them (i) in favor of the adoption and approval of the Merger Agreement, the Liquidia Merger and the consummation of the Merger Transaction and the transactions contemplated therein, and the other related ancillary agreements at every meeting of the stockholders of our company at which such matters are considered and at every adjournment or postponement thereof; and (ii) against (1) any “takeover proposal” (as defined below) with respect to our company or HoldCo, (2) any action, proposal, transaction or agreement which could reasonably be expected to result in a breach of any covenant, representation or warranty or any other obligation or agreement of our company under the Merger Agreement or of the Supporting Stockholder under the Support Agreement and (3) any action, proposal, transaction or agreement that could reasonably be expected to impede, interfere with, delay, discourage, adversely affect or inhibit the timely consummation of the transactions contemplated in the Merger Agreement and the other ancillary agreements or the fulfillment of each party’s conditions under the Merger Agreement or change in any manner the voting rights of any class of shares of our capital stock (including any amendments to our or HoldCo’s organizational documents).

The power of attorney granted by the Supporting Stockholder therein is a durable power of attorney and shall survive the dissolution, bankruptcy, death or incapacity of the Supporting Stockholder. The proxy and power of attorney granted thereunder shall terminate upon the termination of the Support Agreement.

To the extent applicable, the Supporting Stockholders also (i) waive, and agree not to assert or perfect, any rights of appraisal or rights to dissent from the Merger Transaction that the Supporting Stockholder may have by virtue of ownership of the shares of our common stock and (ii) agree (A) not to commence or participate in and (B) to take all actions necessary to opt out of any class in any class action with respect to any claim, derivative or otherwise, against us, HoldCo, Liquidia Merger Sub, RareGen, RareGen Merger Sub or any of their respective affiliates relating to the negotiation, execution or delivery of the Support Agreement or the Merger Agreement or the consummation of the transactions contemplated thereby, including any claim (1) challenging the validity of, or seeking to enjoin the operation of, any provision of the Support Agreement or the Merger Agreement or (2) alleging a breach of any fiduciary duty of our board of directors in connection with the Support Agreement, the Merger Agreement or the transactions contemplated thereby.

In addition, Mr. Fowler, Canaan VIII L.P. and Eshelman Ventures, LLC and Mr. Eshelman have agreed not to transfer any of their shares of our common stock, and each Supporting Stockholder has agreed not to deposit any such shares into a voting trust or enter into a voting agreement or arrangement with respect to such shares and not to grant a proxy or power of attorney in respect of such shares until the termination date of the Support Agreement.

As of the date of this proxy statement/prospectus, the Supporting Stockholders collectively hold and are entitled to vote in the aggregate approximately 34.5% of the issued and outstanding shares of our common stock entitled to vote at the special meeting of our stockholders.

Litigation Funding and Indemnification Agreement

Prior to the effective time of the Merger Transaction, RareGen will enter into the litigation funding and indemnification agreement with the Members’ Representative pursuant to which, in the event the financing agreement is terminated or otherwise rendered non-operable by failure of either party thereto or by operation of law or in the event Henderson is no longer required to, or fails to timely, make payments to RareGen pursuant to the financing agreement, the Members’ Representative will make payments to or on behalf of RareGen to be used by RareGen exclusively for the payment of counsel fees and litigation expenses incurred in connection with the UTC/Smiths Medical litigation described under “RareGen’s Business: Legal Proceedings and Related Agreements” beginning on page 76. In consideration for making such payments to or on behalf of RareGen, the Members’ Representative is entitled to an amount equal to the litigation proceeds actually received by RareGen or any of its affiliates in connection with the UTC/Smiths Medical litigation, less any and all amounts payable to Henderson pursuant to the financing agreement and all litigation expenses and counsel fees then payable by the Members’ Representative pursuant to the litigation funding and indemnification agreement and for which RareGen has not been reimbursed for pursuant to the litigation funding and indemnification agreement. If there are no litigation proceeds (after deducting any amounts payable to Henderson pursuant to the financing agreement), then no amount shall be payable to the Members’ Representative, and if there are litigation proceeds but they are less (after deducting any amounts payable to Henderson pursuant to the financing agreement) than the amount necessary to pay the Members’ Representative the entirety of its share, RareGen shall not be obligated to pay the difference to the Members’ Representative. In the event that RareGen is required under the financing agreement to pay any litigation proceeds into a lockbox account, escrow account or other similar restricted account, then no portion of such litigation proceeds shall become payable to the Members’ Representative pursuant to the

139

TABLE OF CONTENTS

litigation funding and indemnification agreement unless and until such funds are released to RareGen from such lockbox account, escrow account or other restricted account.

The Members’ Representative has agreed to indemnify RareGen and its affiliates from any losses and fees incurred in connection with (i) any claim of United Therapeutics or Smiths Medical or any other party against RareGen or its affiliates in connection with or resulting in any way from the UTC/Smiths Medical litigation, or (ii) any breach by the Members’ Representative of the terms of the litigation funding and indemnification agreement. RareGen has agreed to indemnify the Members’ Representative and its affiliates from any losses and fees incurred in connection with any breach by RareGen of the terms of the litigation funding and indemnification agreement.

Post-Closing Transfer Restrictions

In connection with the Merger Transaction, each current RareGen member receiving HoldCo common stock in exchange for their RareGen common units agreed that, without the prior written consent of HoldCo, as applicable, it will not, subject to limited exceptions, among other things, offer, sell, contract to sell, pledge, or otherwise dispose of, or to enter into any hedging or swap transaction with respect to, any shares of HoldCo common stock acquired at the closing of the Merger Transaction for a period ending six months after the closing date of the Merger Transaction.

A lock-up agreement will be entered into and effective on the closing date of the Merger Transaction. RareGen members will not enter into a lock-up agreement for any shares of HoldCo common stock acquired after the closing date of the Merger Transaction, such as upon the acquisition of Holdback Shares or Net Sales Earnout Shares.

The foregoing does not prohibit transfers or dispositions by current RareGen members:

•

with the prior written consent of HoldCo;

•

as a transfer pursuant to a bona fide third party tender offer, merger, consolidation or other similar transaction involving a change of control of HoldCo;

•

as a distribution to limited partners, members or stockholders of a holder of HoldCo common stock;

•

as a transfer by a business entity to another business entity so long as the transferee controls or is under common control with the holder, such as the proposed post-closing transfer of shares of HoldCo common stock from PBM Capital Finance to PD Joint Holdings;

•

as a transfer to a legal representative, heir, beneficiary or a member of the holder’s immediate family;

•

as a transfer to any trust for the direct or indirect benefit the holder or the immediate family of the holder and/or charitable organizations;

•

as a bona fide gift, including pursuant to a domestic order or a negotiated divorce settlement, or estate or intestate succession; or

•

as a transfer by operation of law, including pursuant to a court or regulatory agency order, a qualified domestic relations order or in connection with a divorce settlement.

Unless a transfer or disposition is made with the written consent of HoldCo, the permitted transfers and dispositions described above may not be made by any current RareGen member unless (i) the transfer or disposition does not result in any public disclosure or filing under the Exchange Act reporting a reduction in beneficial ownership of shares of common stock being required or voluntarily made during the applicable lock-up period and (ii) the transferee of each such shares agrees to be bound by the lock-up agreement.

For the avoidance of doubt, the lock-up agreement shall not apply to shares of HoldCo common stock, or any derivative securities of our company or HoldCo, which are beneficially owned before or following the date of the applicable lock-up agreement, other than the particular shares subject to the lock-up agreement.

Required Vote; Board Recommendation

To approve this Proposal 1, if a quorum is present or represented by proxy at the special meeting, stockholders holding a majority of our common stock entitled to vote on the matter must vote “FOR” the proposal, meaning that the votes cast by the stockholders “FOR” the approval of the proposal must equal a majority of the shares outstanding. If a stockholder votes to “ABSTAIN,” it has the same effect as a vote “AGAINST.” Broker non-votes will have the same effect as a vote “AGAINST” this proposal. If no vote is specified on the proxy and in the absence of directions to the contrary, the shares will be voted “FOR” the Merger Agreement and the Liquidia Merger.

UPON THE RECOMMENDATION OF THE LIQUIDIA TECHNOLOGIES BOARD OF DIRECTORS, THE LIQUIDIA TECHNOLOGIES BOARD OF DIRECTORS RECOMMENDS THAT LIQUIDIA TECHNOLOGIES STOCKHOLDERS VOTE “FOR” THE ADOPTION OF THE MERGER AGREEMENT AND APPROVAL OF THE LIQUIDIA MERGER.

DIRECTORS AND OFFICERS OF HOLDCO FOLLOWING COMPLETION OF THE MERGER TRANSACTION

HoldCo’s bylaws, which are substantially identical to our amended and restated bylaws, provide that the authorized number of directors of HoldCo shall not be less than three nor more than 11. Eight directors are currently serving on our and HoldCo’s board of directors, consisting of Dr. Stephen Bloch, Neal F. Fowler, Katherine Rielly-Gauvin, Dr. Joanna Horobin, Arthur Kirsch, Dr. Seth Rudnick, Raman Singh and Dr. Ralph Snyderman. The HoldCo board of directors is authorized to increase or decrease the total number of directors within the limitations prescribed by HoldCo’s bylaws.

Directors

Drs. Bloch, Horobin, Rudnick and Snyderman, Ms. Rielly-Gauvin and Messrs. Fowler, Kirsch and Singh, all of whom are current Liquidia Technologies directors, were appointed as HoldCo directors on June 28, 2020 in connection with the formation of HoldCo. Effective and contingent upon the consummation of the Merger Transaction, the HoldCo board of directors will increase the authorized number of directors from eight to nine. Upon the completion of the Merger Transaction, Dr. Ralph Snyderman has agreed to resign from the boards of directors of our company and HoldCo and Dr. Jeffs and Mr. Manning will be appointed as directors of HoldCo. As such, post-closing, the HoldCo board of directors will be comprised of nine members, consisting of Drs. Bloch, Horobin, Jeffs and Rudnick, Ms. Rielly-Gauvin and Messrs. Fowler, Kirsch, Manning and Singh.

Classified Board

HoldCo’s bylaws and certificate of incorporation divides the HoldCo board of directors into three classes with staggered three-year terms. At the 2019 annual meeting of stockholders, our stockholders elected Drs. Bloch and Snyderman as Class I directors, and in September 2019 our board of directors appointed Dr. Horobin as a Class I director, with a term expiring at the 2022 annual meeting of stockholders. At the 2020 annual meeting of stockholders, our stockholders elected Ms. Rielly-Gauvin, Dr. Rudnick and Mr. Singh as Class II directors with a term expiring at the 2023 annual meeting of stockholders. Messrs. Fowler and Kirsch are current Class III directors of our company with a term expiring at the 2021 annual meeting of stockholders. In forming HoldCo, the current Liquidia Technologies classifications were incorporated. Upon the closing of the Merger Agreement, Dr. Jeffs and Mr. Manning will be appointed as Class I and Class III directors, respectively, to fill the vacancies caused by the increase in authorized number of directors and the resignation of Dr. Snyderman, respectively. Pursuant to the HoldCo certificate of incorporation and bylaws, no one class of directors is to have more than one director more than any other class of directors. At each succeeding annual meeting of HoldCo stockholders, directors will be elected for a full three-year term to succeed the directors of the class whose terms expire at such annual meeting.

Board Committees

The HoldCo board of directors currently has four standing committees: an Audit Committee, a Compensation Committee, a Nominating and Corporate Governance Committee and a Research and Development Committee. These committees, their principal functions and their respective memberships are described below.

Audit Committee

The Audit Committee of the HoldCo board of directors will oversee the quality and integrity of HoldCo’s financial statements and other financial information, accounting and financial reporting processes, internal controls and procedures for financial reporting and internal audit function. It will also oversee the audit and other services provided by HoldCo’s independent auditor and is directly responsible for the appointment, independence, qualifications, compensation and oversight of the independent auditor. In addition, HoldCo’s audit committee is responsible for reviewing HoldCo’s compliance with legal and regulatory requirements, and it assists the HoldCo board of directors in an initial review of recommendations to the HoldCo board of directors regarding proposed business transactions.

HoldCo’s Audit Committee following completion of the Merger Transaction will be comprised of Dr. Bloch and Messrs. Kirsch and Singh, with Mr. Kirsch serving as Chairperson. All members of HoldCo’s Audit Committee meet the requirements for financial literacy under the applicable rules and regulations of the SEC and Nasdaq. HoldCo’s board of directors has determined that Mr. Kirsch is an “audit committee financial expert” as defined under the applicable rules of the SEC and has the requisite financial sophistication as defined under the applicable rules and regulations of Nasdaq. Under the rules of the SEC, members of the audit committee must also meet heightened independence standards. HoldCo’s board of directors has determined that each of Dr. Bloch and Messrs. Kirsch and Singh are independent under the heightened audit committee independence standards of the SEC and Nasdaq. The Audit Committee operates under a written charter that satisfies the applicable standards of the SEC and Nasdaq.

Compensation Committee

The Compensation Committee of HoldCo’s board of directors will review and determine the compensation of all of its executive officers and establishes HoldCo’s compensation policies and programs. Specific responsibilities of HoldCo’s Compensation Committee include, among other things, evaluating the performance of its Chief Executive Officer and determining its Chief Executive Officer’s compensation. It will also determine the compensation of HoldCo’s other executive officers. In addition, HoldCo’s Compensation Committee will administer all equity compensation plans and has the authority to grant equity awards subject to the terms and conditions of such equity compensation plans. HoldCo’s Compensation Committee will also review and approve various other compensation policies and matters, including establishing policies and making recommendations to HoldCo’s board of directors regarding director compensation. In reviewing and advising the HoldCo board of directors, the Compensation Committee will consider aligning the level and structure of compensation with the long-term interest and risk policies of HoldCo, and will create a compensation structure that is appropriate to attract, retain and motivate (a) directors to provide good stewardship of HoldCo, and (b) key management personnel to successfully manage HoldCo, while not paying more than necessary to accomplish the foregoing. HoldCo’s Compensation Committee may also review and discuss with management the compensation discussion and analysis that HoldCo may be required from time to time to include in SEC filings, and it may prepare a compensation committee report on executive compensation as may be required from time to time to be included in HoldCo’s annual proxy statements or annual reports on Form 10-K filed with the SEC.

In fulfilling its responsibilities, the Compensation Committee shall, to the extent permitted by the applicable rules of Nasdaq and applicable law, be entitled to delegate any or all of its responsibilities to one or more subcommittees of the Compensation Committee comprised of one or more members of the Compensation Committee. In connection with its evaluations and determinations in 2019, at management’s recommendation the Compensation Committee of our board of directors retained the services of Radford/

In computing the number of shares beneficially owned by an individual or entity and the percentage ownership of that person, shares of common stock subject to options, convertible securities or other rights, held by such person that are currently exercisable or will become exercisable within 60 days of July 15, 2020, are considered outstanding. We did not, however, deem such shares outstanding for the purpose of computing the percentage ownership of any other person. Unless otherwise indicated, to our knowledge, the persons and entities named in the table below have sole voting and sole investment power with respect to all shares that they beneficially own, subject to community property laws where applicable. The information in the table below does not necessarily indicate beneficial ownership for any other purpose, including for purposes of Sections 13(d) and 13(g) of the Securities Act.

Security Ownership of Certain Beneficial Owners and Management of HoldCo Following Completion of the Merger Transaction

The following table sets forth information regarding the beneficial ownership (as such term is defined in Rule 13d-3 under the Exchange Act) of HoldCo’s common stock as of July 15, 2020, giving effect to the Merger Transaction (excluding the issuance of the Holdback Shares), except as noted below, by:

•

each of HoldCo’s directors following completion of the Merger Transaction;

•

each of HoldCo’s named executive officers (as defined in Item 402(m)(2) of Regulation S-K) following completion of the Merger Transaction;

•

each person, or group of affiliated persons, who is known by HoldCo to beneficially own more than five percent of HoldCo’s common stock following completion of the Merger Transaction; and

•

all of HoldCo’s directors and executive officers as a group following completion of the Merger Transaction.

HoldCo has determined beneficial ownership in accordance with the rules of the SEC, which generally means that a person has beneficial ownership of a security if he, she or it possesses sole or shared voting or investment power of that security, including our options, restricted stock units or warrants that are currently exercisable or exercisable within 60 days of July 15, 2020 which will be assumed by HoldCo upon consummation of the Merger Transaction. In computing the number of shares beneficially owned by an individual or entity and the percentage ownership of that person, shares of HoldCo common stock subject to options, convertible securities or other rights to be assumed by HoldCo, held by such person that are currently exercisable or will become exercisable within 60 days of July 15, 2020, giving effect to the Merger Transaction, are considered outstanding. HoldCo did not, however, deem such shares outstanding for the purpose of computing the percentage ownership of any other person. Unless otherwise indicated, to HoldCo’s knowledge, the persons and entities named in the table below have sole voting and sole investment power with respect to all shares that they beneficially own, subject to community property laws where applicable. The information in the table below does not necessarily indicate beneficial ownership for any other purpose, including for purposes of Sections 13(d) and 13(g) of the Securities Act.

HoldCo has based its calculation of the percentage of beneficial ownership on 43,229,890 shares of HoldCo common stock outstanding as of July 15, 2020, giving effect to the Merger Transaction (excluding the issuance of the Holdback Shares).

Narrative Disclosure to Summary Compensation Table

Base Salary

Messrs. deGoa and Moomaw receive a base salary to compensate them for services rendered to RareGen. The base salary payable to each such executive is intended to provide a fixed component of compensation reflecting the executive’s skill set, experience, role and responsibilities. Pursuant to Messrs. deGoa’s and Moomaw’s employment agreements, base salary is subject to adjustment as determined by the RareGen board of directors based on RareGen policy and the executive’s contributions to RareGen’s business.

Bonuses

Prior to such date that RareGen members have received, in the aggregate, distributions from RareGen in an amount equal to their aggregate capital contributions to RareGen, or $25 million, which date is referred to as the “Payback Date,” each of Messrs. deGoa and Moomaw shall be entitled to receive an annual cash bonus with respect to each calendar year during their respective employment, to be calculated as a percentage of RareGen’s “Net Income” (as defined below) in the applicable calendar year. Specifically, prior to the Payback Date (i) for the first $30 million of Net Income in a calendar year, (ii) for that portion of the Net Income in such calendar year that exceeds $30 million and is less than or equal to $60 million and (iii) for that portion of the Net Income in such calendar year that exceeds $60 million, each of Messrs. deGoa and Moomaw shall receive 0.50%, 1.00% and 1.50% of RareGen’s Net Income, respectively. Following the Payback Date, the respective percentages of Net Income in each of (i), (ii) and (iii) which Messrs. deGoa and Moomaw are entitled to receive increases to 2.00%, 2.50% and 3.00%, respectively.

“Net Income” is defined in each executive’s employment agreement as, for any calendar year, the net income of RareGen as determined by GAAP, minus (i) all cash reserves reasonably set aside by the RareGen board of directors in its sole and absolute discretion to fund working capital, capital expenditures, acquisitions and future contingencies or to otherwise accomplish RareGen’s business, plus (ii) any amounts previously set aside as reserves, deemed by the RareGen board of directors to no longer be required to be maintained as reserves, minus (iii) the amount by which the Net Income in the immediately preceding calendar year was less than $0.

deGoa and Moomaw Employment Agreements

RareGen entered into an employment agreement with Mr. Moomaw, RareGen’s Chief Operating Officer, on August 7, 2018 and with Mr. deGoa, RareGen’s Chief Executive Officer, on September 21, 2018, which we refer to together as the “RareGen Employment Agreements” and individually as a “RareGen Employment Agreement”, pursuant to which Messrs. Moomaw and deGoa are each entitled to receive an annual base salary of $300,000. Please also see the description of Messrs. Moomaw’s and deGoa’s annual cash bonuses on page 162 of this proxy statement/prospectus under the section entitled “Bonuses.” Pursuant to each RareGen Employment Agreement, Messrs. deGoa and Moomaw are employed by RareGen on an “at will” basis until such employment is terminated by either party. The RareGen Employment Agreements are governed by the laws of the Commonwealth of Virginia.

The RareGen Merger constitutes a Sale Transaction (defined below) under the RareGen Employment Agreements. In the event of a Sale Transaction, Messrs. Moomaw and deGoa are eligible to receive a one-time bonus equal to two percent and four percent, respectively, of the Net Sales Proceeds (defined below). The amounts to be paid to Messrs. deGoa and Moomaw due to the consummation of the Merger Transaction are included in the transaction expenses to be paid by RareGen’s members and cannot be calculated until closing. Neither Mr. Moomaw nor Mr. deGoa are eligible to receive any further bonuses in the event of a Sale Transaction. Any bonus paid in the event of a Sale Transaction is paid in lieu of, and not in addition to, any bonus that the executive would have otherwise been eligible to receive.

“Net Sales Proceeds” is defined in the RareGen Employment Agreements as the total amount of cash and the fair market value of other property actually paid to the members of RareGen in their capacity as such in connection with a Sale Transaction. If all or any portion of the Net Sales Proceeds are (i) subject to increase by contingent payments related to future events (including any such contingent payments held in escrow), (ii) of a determined amount but are to be paid over time, or (iii) held by RareGen as reserves for potential liabilities or future contingencies, the portion of the bonus payable in the event of a Sales Transaction shall be payable as and when such payments are made to RareGen’s members, regardless of the date on which made.

“Sale Transaction” is defined in the RareGen Employment Agreements as the date on which RareGen closes a transaction pursuant to which: (A) any person, including a “group” as defined below, will acquire ownership of all or substantially all of RareGen’s equity, excluding any acquisition of stock by a person or group of persons who were members of RareGen immediately prior to such acquisition; or (B) any person, including a “group” as defined below, will acquire all or substantially all of the assets of RareGen. For purposes of this definition, the term “group” has the same meaning as in Section 13(d)(3) of the Exchange Act.

Messrs. Moomaw and deGoa have each agreed under the RareGen Employment Agreements that all information, whether or not in writing, relating to the business, technical or financial affairs of RareGen is exclusive property of RareGen. Each executive further agreed to customary (i) confidentiality provisions, (ii) invention assignment provisions; (iii) non-competition restrictions during their employment and for a period of six months after the expiration or termination of their employment; and (iv) non-solicitation restrictions during their employment and for a period of 12 months after the expiration or termination of their employment.

The RareGen Employment Agreements provide that Messrs. Moomaw and deGoa may terminate their employment for any reason with at least 30 days’ notice prior to the effective date of termination and are entitled to their base salary and benefits otherwise payable through the last day of their employment. RareGen may elect to terminate each executive’s employment at any time during such 30-day notice period. Messrs. Moomaw and deGoa are not entitled to receive any other compensation or benefits upon such termination.

RareGen may terminate the RareGen Employment Agreements with Cause (defined below), or upon such executive’s permanent disability upon written notice to Messrs. Moomaw and deGoa, as applicable. In such instance, the executive is entitled to receive his base salary and benefits otherwise payable through

163

TABLE OF CONTENTS

the last day of their employment by RareGen and are not entitled to receive any other compensation or benefits. Upon the executive’s death, his employment will terminate immediately and RareGen will not have any further liability or obligation to such executive other than any accrued but unpaid salary through the date of the executive’s death.

“Cause” is defined in the RareGen Employment Agreements as (i) the executive’s embezzlement, theft, fraud, misappropriation of any business opportunity of RareGen, gross negligence, or a breach of any fiduciary duty owned to RareGen, (ii) intentional misconduct involving RareGen or any of its suppliers or customers that adversely affects or may so affect the business or reputation of RareGen, (iii) conviction of the executive of a felon or entry of a pleading of guilty or nolo contendere by the executive to any felony; (iv) the RareGen board of directors’ good faith finding of the executive’s continued failure to perform his duties and responsibilities to RareGen that remains uncured for 30 days after receipt of written notice of such finding, (v) the executive’s unauthorized use or disclosure of any of RareGen’s proprietary information or trade secrets or any information entrusted to RareGen by a supplier, customer or other third party (except disclosures made in good faith in the ordinary course of business, consistent with past practices) and (vi) the RareGen board of directors’ good faith finding of the executive’s material breach of or default under any of his obligations under any written agreements with RareGen (including the RareGen Employment Agreement).

RareGen may terminate either RareGen Employment Agreement without Cause (including any termination without Cause after a change of control of RareGen) with thirty (30) days’ written notice to Messrs. Moomaw or deGoa, as applicable. In such instance, Messrs. Moomaw and deGoa are entitled to receive a severance payment equal to any annual cash bonus as described on page 162 of this proxy statement/prospectus under the section entitled “Bonuses” that would have been payable if the calendar year had ended on the same date on which the executive’s employment terminates; provided that such executive shall not be entitled to any severance payments unless he executes a severance agreement releasing any and all claims he may have against RareGen.

It is a condition precedent to our consummation of the Merger Transaction that Mr. deGoa’s RareGen Employment Agreement be terminated as of the effective time of the Merger Transaction, and RareGen shall not have any severance or bonus obligations pursuant to Mr. deGoa’s employment agreement as of such effective time.

Director and Officer Indemnification

RareGen’s operating agreement also requires RareGen to indemnify its officers and directors for such indemnifiable losses, and to advance amounts incurred by such director or officer in defending any proceeding, with such amounts to be repaid by the director or officer if such person is ultimately adjudicated to be ineligible for indemnification. In addition, RareGen has entered into agreements to indemnify Mr. Moomaw and Dr. Jeffs. These indemnification agreements, among other things, require RareGen to indemnify Mr. Moomaw and Dr. Jeffs for certain expenses, including attorneys’ fees, judgments, fines and settlement amounts incurred by them arising out of their services as a director or officer, or any other company or enterprise to which the person provides services at RareGen’s request and out of any claim of breach or alleged breach of any obligations of Mr. Moomaw and Dr. Jeffs to United Therapeutics Corporation.

The HoldCo certificate of incorporation is identical to our amended and restated certificate of incorporation, as amended, currently in effect, other than (i) the company name and (ii) the number of shares of common stock authorized thereunder, with our company having 60,000,000 shares of our common stock authorized and HoldCo having 80,000,000 shares of its common stock authorized. The HoldCo bylaws are identical to our amended and restated bylaws currently in effect, other than the company name and the inclusion of a federal exclusive forum provision for claims arising under the Securities Act. This section also summarizes relevant provisions of the DGCL. The terms of HoldCo’s certificate of incorporation and bylaws, as well as the terms of the DGCL, are more detailed than the general information provided below. Therefore, you should carefully consider the actual provisions of these documents and the DGCL. The HoldCo amended and restated certificate of incorporation and HoldCo bylaws are each attached as exhibits to this proxy statement/prospectus.

General

The total number of shares of capital stock that HoldCo has authorized is 90,000,000, divided into two classes consisting of (i) 80,000,000 shares of common stock, $0.001 par value per share, and (ii) 10,000,000 shares of preferred stock, $0.001 par value per share.

Common Stock

The holders of HoldCo common stock are entitled to one vote per share on all matters to be voted upon by the stockholders. At a meeting of stockholders at which a quorum is present, for all matters other than the election of directors, an affirmative vote of the majority of shares entitled to vote on a matter and that are represented either in person or by proxy at a meeting of stockholders decides all questions, unless the matter is one upon which a different vote is required by express provision of law or HoldCo’s certificate of incorporation or bylaws, each as may be amended from time to time. The holders of HoldCo common stock are entitled to receive ratably those dividends, if any, that may be declared from time to time by HoldCo’s board of directors out of funds legally available, subject to preferences that may be applicable to preferred stock, if any, then outstanding. In the event of a liquidation, dissolution or winding up of HoldCo, the holders of common stock will be entitled to share ratably in all assets remaining after payment of liabilities, subject to prior distribution rights of preferred stock, if any, then outstanding. The HoldCo common stock has no preemptive or conversion rights or other subscription rights. There are no redemption or sinking fund provisions applicable to the common stock. All outstanding shares of HoldCo common stock are fully paid and non-assessable.

Preferred Stock

The HoldCo board of directors is authorized to issue preferred stock in one or more series, to establish the number of shares to be included in each such series and to fix the designation, powers, preferences and rights of these shares and any qualifications, limitations or restrictions thereof. The issuance of preferred stock may have the effect of delaying, deferring or preventing a change in control of HoldCo without further action by the stockholders and may adversely affect the voting and other rights of the holders of HoldCo common stock. The issuance of preferred stock with voting and conversion rights may adversely affect the voting power of the holders of HoldCo common stock, including the loss of voting control to others. At present, HoldCo has no plans to issue any of the preferred stock.

Warrants

As of July 15, 2020, we had outstanding warrants to purchase an aggregate of 106,274 shares of our common stock at an exercise price of $0.0168 per share. These warrants expire on December 31, 2026. Upon consummation of the Merger Transaction, HoldCo will assume these warrants, which will become exercisable for HoldCo common stock at the same exercise price and on the same other terms as contained in our warrants.

Registration Rights

Pursuant to a Limited Waiver and Modification to the Merger Agreement dated as of August 3, 2020, HoldCo has agreed to file with the SEC a resale registration statement as promptly as practicable following the closing of the Merger Transaction to register for resale the shares of HoldCo common stock issuable to RareGen members in the Merger Transaction. HoldCo has agreed to use reasonable best efforts to cause the resale registration statement to be declared effective within 60 days following the closing date of the Merger Transaction.

Additionally, we entered into a Seventh Amended and Restated Investors’ Rights Agreement, or IRA, on February 2, 2018 with our then-largest stockholders. Subject to the terms of this agreement, Holders, as defined in the Seventh Amended and Restated IRA, of shares having registration rights, or Registrable Securities, as defined in the Seventh Amended and Restated IRA, can demand that we file a registration statement or request that their shares be covered by a registration statement that we are otherwise filing, until the earliest to occur of: (i) five years following the consummation of our initial public offering, or July 30, 2023, (ii) as to any Holder, such earlier time after our initial public offering at which such Holder can sell all Registrable Securities held by such Holder (together with any affiliate of the Holder with whom such Holder must aggregate its sales under Rule 144) in a single three (3)-month period without registration in compliance with Rule 144 of the Securities Act or (iii) after the consummation of a “Liquidation Event,” as defined in the Seventh Amended and Restated IRA.

Pursuant to the IRA, the IRA shall inure to the benefit of and be binding upon the respective successors and assigns of the parties, including HoldCo as our successor following consummation of the Merger Transaction.

Demand Registration Rights. At any time after six months following the closing of our initial public offering, or January 30, 2019, subject to certain exceptions set forth in the Seventh Amended and Restated IRA, if the Holders of at least a majority of the common stock issued upon conversion of the Series C, Series C-1 and Series D preferred stock, or the Required Holders, demand that we file a registration statement covering the registration of Registrable Securities with an anticipated aggregate offering price of at least $10 million, we are required to use all commercially reasonable efforts to effect, as soon as practicable, the registration under the Securities Act of all Registrable Securities requested to be registered.

Form S-3 Registration Rights. If we receive from the Holders of Registrable Securities a written request that we effect a registration on Form S-3, we are required to provide written notice of the proposed registration to all other Holders and use all commercially reasonable efforts to effect the registration of such shares on Form S-3; provided, however, that such Form S-3 registration right is subject to a number of exceptions, such as us being eligible to use Form S-3 at the time such Form S-3 registration request is made, the proposed sale of Registrable Securities to be registered on Form S-3 having an aggregate price to the public (net of any underwriters’ discounts or commissions) of at least $5 million and us not being required to file more than two registration statements on Form S-3 in a 12-month period. Furthermore, we have the ability to delay the filing of a registration statement under specified conditions, such as for a period of time following the effective date of a prior registration statement, if our board of directors deems it detrimental to us and our stockholders to delay the filing. Such postponements cannot exceed 90 days during any 12-month period and cannot be made more than once in any 12-month period.

Piggyback Registration Rights. If we propose to register any of our securities under the Securities Act in connection with the public offering of such securities, we are required to, at such time, promptly give each Holder party to the Seventh Amended and Restated IRA written notice of such registration. Upon the written request of each such Holder given within 20 days after receipt of our registration notice, we are required to use all commercially reasonable efforts to cause to be registered under the Securities Act all of the Registrable Securities that each holder requests to be registered. In connection with any such offering, we are not required to include any of the Holders’ securities in such underwriting unless they accept the terms of the underwriting as agreed between us and the underwriters selected by us and enter into an underwriting agreement in customary form with such underwriters, and then only in such quantity as the underwriters determine in their sole discretion will not jeopardize the success of the offering by us. If marketing factors require a limitation of the number of shares to be underwritten, then the number of shares that may be included in the underwriting will be allocated, first, to us; second, to the Holders other than the Common

168

TABLE OF CONTENTS

Holders on a pro rata basis based on the total number of Registrable Securities held by such Holders; third, to the Common Holders on a pro rata basis based on the total number of Registrable Securities held by the Common Holders; and fourth, to any stockholder other than a Holder and/or Common Holder on a pro rata basis.

Expenses of Registration. We will pay all expenses, other than underwriting discounts and commissions, related to any demand, Form S-3 or piggyback registration, including without limitation all registration, filing and qualification fees, printers’ and accounting fees, fees and disbursements of counsel for us and the reasonable fees and disbursements of one counsel for the selling Holders, not to exceed $50,000.

Indemnification. The Seventh Amended and Restated IRA contains customary cross-indemnification provisions under which we are obligated to indemnify the selling stockholders in the event of material misstatements or omissions or other “Violation,” as defined in the Seventh Amended and Restated IRA, in the registration statement attributable to us, and they are obligated to indemnify us for material misstatements or omissions or other Violation attributable to them.

Termination of Registration Rights. All registration rights granted under the IRA will terminate on the fifth anniversary of the completion of our initial public offering, or July 30, 2023.

Anti-Takeover Effects of HoldCo’s Charter and Bylaws and Delaware Law

Some provisions of the DGCL and HoldCo’s certificate of incorporation and bylaws could make the following transactions more difficult:

• acquisition of HoldCo by means of a tender offer, a proxy contest or otherwise; and

• removal of HoldCo’s incumbent officers and directors.

These provisions, summarized below, are expected to discourage and prevent coercive takeover practices and inadequate takeover bids. These provisions are designed to encourage persons seeking to acquire control of HoldCo to negotiate first with the HoldCo board of directors. They are also intended to provide HoldCo management with the flexibility to enhance the likelihood of continuity and stability if the HoldCo board of directors determines that a takeover is not in the best interests of its stockholders. These provisions, however, could have the effect of discouraging attempts to acquire HoldCo, which could deprive HoldCo’s stockholders of opportunities to sell their shares of HoldCo common stock at prices higher than prevailing market prices. HoldCo believes that the benefits of these provisions, including increased protection of HoldCo’s potential ability to negotiate with the proponent of an unfriendly or unsolicited proposal to acquire or restructure HoldCo, outweigh the disadvantages of discouraging takeover proposals, because negotiation of takeover proposals could result in an improvement of their terms.

Election and Removal of Directors

HoldCo’s certificate of incorporation and bylaws contain provisions that establish specific procedures for appointing and removing members of the HoldCo board of directors. Under HoldCo’s certificate of incorporation and bylaws, the HoldCo board of directors consists of three classes of directors: Class I, Class II and Class III. A nominee for director shall be elected to the HoldCo board of directors upon a plurality of the votes cast by the stockholders entitled to vote at the election. Each director will serve a three-year term and will stand for election upon the third anniversary of the annual meeting at which such director was elected. In addition, HoldCo’s certificate of incorporation and bylaws provide that vacancies and newly created directorships on the HoldCo board of directors may be filled only by a majority of the directors then serving on the board. Under HoldCo’s certificate of incorporation, directors may be removed by the stockholders only by the affirmative vote of the holders of at least a majority of the voting power of all of the then-outstanding shares of HoldCo’s capital stock entitled to vote generally in the election of directors, voting together as a single class.

Authorized but Unissued Shares. The authorized but unissued shares of common stock and preferred stock are available for future issuance without any further vote or action by HoldCo’s stockholders. These additional shares may be utilized for a variety of corporate purposes, including future public offerings to raise additional capital, corporate acquisitions and employee benefit plans. The existence of authorized but

169

TABLE OF CONTENTS

unissued shares of common stock and preferred stock could render more difficult or discourage an attempt to obtain control over HoldCo by means of a proxy contest, changes in HoldCo’s management, tender offer, merger or otherwise. In particular, the authorization of undesignated preferred stock makes it possible for the HoldCo board of directors to issue preferred stock with voting or other rights or preferences that could impede the success of any attempt to change control of HoldCo.

Stockholder Action; Advance Notification of Stockholder Nominations and Proposals. HoldCo’s certificate of incorporation and bylaws require that any action required or permitted to be taken by its stockholders must be effected at a duly called annual or special meeting of stockholders and does not allow for stockholders to act by written consent without a meeting. In addition, HoldCo’s bylaws provide that candidates for director may be nominated and other business brought before an annual meeting only by the HoldCo board of directors or by a stockholder who gives written notice to HoldCo no later than 90 days prior to nor earlier than 120 days prior to the first anniversary of the last annual meeting of stockholders. These provisions may have the effect of deterring unsolicited offers to acquire HoldCo or delaying changes in HoldCo’s management, which could depress the market price of the common stock.

Special Stockholder Meetings. Under HoldCo’s certificate of incorporation and bylaws, only the HoldCo board of directors, the Chairman of the board of directors or HoldCo’s Chief Executive Officer may call special meetings of stockholders.

Delaware Anti-Takeover Law. HoldCo is subject to Section 203 of the DGCL, which is an anti-takeover law. In general, Section 203 prohibits a publicly held Delaware corporation from engaging in a business combination with an interested stockholder for a period of three years following the date that the person became an interested stockholder, unless the business combination or the transaction in which the person became an interested stockholder is approved in a prescribed manner. Generally, a business combination includes a merger, asset or stock sale, or another transaction resulting in a financial benefit to the interested stockholder. Generally, an interested stockholder is a person who, together with affiliates and associates, owns 15% or more of the corporation’s voting stock. The existence of this provision may have an anti-takeover effect with respect to transactions that are not approved in advance by the HoldCo board of directors, including discouraging attempts that might result in a premium over the market price for the shares of common stock held by stockholders.

No Cumulative Voting. Under Delaware law, cumulative voting for the election of directors is not permitted unless a corporation’s certificate of incorporation authorizes cumulative voting. HoldCo’s certificate of incorporation does not provide for cumulative voting in the election of directors. Cumulative voting allows a minority stockholder to vote a portion or all of its shares for one or more candidates for seats on the HoldCo board of directors. Without cumulative voting, a minority stockholder will not be able to gain as many seats on the HoldCo board of directors based on the number of shares of HoldCo stock the stockholder holds as the stockholder would be able to gain if cumulative voting were permitted. The absence of cumulative voting makes it more difficult for a minority stockholder to gain a seat on the HoldCo board of directors to influence its decision regarding a takeover.

Amendment of Charter Provisions. The amendment of certain of the above provisions in HoldCo’s certificate of incorporation and bylaws requires approval by holders of at least a majority of HoldCo’s outstanding capital stock entitled to vote generally in the election of directors.

These and other provisions could have the effect of discouraging others from attempting hostile takeovers, and, as a consequence, they may also inhibit temporary fluctuations in the market price of the common stock that often result from actual or rumored hostile takeover attempts. These provisions may also have the effect of preventing changes in HoldCo’s management. It is possible that these provisions could make it more difficult to accomplish transactions that stockholders might otherwise deem to be in their best interests.

Exclusive Forum

HoldCo’s certificate of incorporation and bylaws provides that, unless HoldCo consents in writing to the selection of an alternate forum, the Court of Chancery of the State of Delaware will, to the fullest extent permitted by law, be the sole and exclusive forum for any (1) derivative action or proceeding brought on

170

TABLE OF CONTENTS

behalf of HoldCo, (2) action asserting a claim of breach of a fiduciary duty owed by any director or officer of HoldCo to HoldCo or its stockholders, (3) action asserting a claim against HoldCo arising pursuant to any provision of the DGCL or HoldCo’s certificate of incorporation or bylaws or (4) action asserting a claim against HoldCo governed by the internal affairs doctrine. Any person or entity purchasing or otherwise acquiring any interest in shares of capital stock of HoldCo shall be deemed to have notice of and consented to the state forum provisions in HoldCo’s certificate of incorporation and bylaws. However, the enforceability of similar forum provisions in other companies’ certificates of incorporation has been challenged in legal proceedings, and it is possible that a court could find these types of provisions to be unenforceable.

HoldCo’s bylaws also provides that, unless HoldCo consents in writing to the selection of an alternative forum, the federal district courts of the United States of America shall be the exclusive forum for the resolution of any complaint asserting a cause of action arising under the Securities Act. Any person or entity purchasing or otherwise acquiring any interest in shares of capital stock of HoldCo shall be deemed to have notice of and consented to the federal forum provisions in HoldCo’s bylaws.

Transfer Agent

The transfer agent and registrar for our common stock, and HoldCo’s common stock following consummation of the Merger Transaction, is Computershare Trust Company, N.A., with an address of 250 Royall Street, Canton, MA 02021.

Listing

HoldCo’s common stock will be listed on the Nasdaq Capital Market under the symbol “LQDA” following consummation of the Merger Transaction.

COMPARISON OF STOCKHOLDER AND UNITHOLDER RIGHTS

General

We are incorporated under the laws of the State of Delaware as a corporation and the rights of our stockholders are governed by the laws of the State of Delaware, including the Delaware General Corporation Law, or the DGCL, our amended and restated certificate of incorporation, as amended, and our amended and restated bylaws. RareGen is formed under the laws of the State of Delaware as a limited liability company and the rights of RareGen unitholders are governed by the DLLCA and RareGen’s operating agreement, effective August 6, 2018, as amended, or the operating agreement. As a result of the Merger Transaction, our stockholders and RareGen unitholders who receive shares of HoldCo common stock will become HoldCo stockholders. HoldCo is incorporated under the laws of the State of Delaware and the rights of HoldCo stockholders will be governed by the laws of the State of Delaware, including the DGCL, HoldCo’s certificate of incorporation and HoldCo’s bylaws. As a result, the rights of our stockholders and RareGen unitholders who become HoldCo stockholders will continue to be governed by the laws of the State of Delaware (although in the case of RareGen, under the DGCL and not the DLLCA) but will also be governed by HoldCo’s certificate of incorporation and HoldCo’s bylaws.

As our successor following the closing of the Merger Transaction, the certificate of incorporation and bylaws of HoldCo are substantially identical to our amended and restated certificate of incorporation, as amended, and amended and restated bylaws. The only changes between the governing documents of our company and HoldCo are (i) the company name, (ii) the number of shares of HoldCo common stock authorized under the HoldCo certificate of incorporation (80,000,000 shares) versus the number of shares of our common stock currently authorized under our amended and restated certificate of incorporation, as amended (60,000,000 shares), and (iii) the addition of an exclusive federal forum provision in HoldCo’s bylaws for the resolution of any complaint asserting a cause of action arising under the Securities Act. As such, the rights of our stockholders contained in our amended and restated certificate of incorporation, as amended, and amended and restated bylaws will not substantially change following the Merger Transaction. See “Description of HoldCo Capital Stock Following Completion of the Merger Transaction” on page 167 for more information.

The following comparison of stockholder and unitholder rights is based on the certificate of incorporation and bylaws of HoldCo that are currently in effect and will be in effect following the completion of the Merger Transaction. The following discussion is not intended to provide a comprehensive discussion of each company’s governing documents and is qualified in its entirety by reference to HoldCo’s certificate of incorporation and bylaws attached to the registration statement of which this proxy statement/prospectus is a part as Exhibit 3.1 and Exhibit 3.2, respectively, and are incorporated by reference herein. Copies of Liquidia’s governing documents have been filed with the SEC. We encourage you to read the governing documents and relevant provisions of the DGCL and the DLLCA.

The DGCL further provides that unless a corporation’s certificate of incorporation or bylaws otherwise provides, directors of a corporation are elected by a plurality of the votes of the shares present in person or represented by proxy and entitled to vote in the election at a stockholders meeting at which a quorum is present. Except as otherwise required by the DGCL or by the certificate of incorporation or bylaws, under the DGCL, all matters brought before a stockholder meeting require the affirmative vote of the majority of the shares present in person or represented by proxy and entitled

Votes on Mergers, Consolidations, Sales or Leases of Assets and Certain Other Transactions

HoldCo. Under the DGCL, a merger, consolidation or sale of all or substantially all of a corporation’s assets generally must be approved by a majority of the outstanding stock of the corporation entitled to vote thereon. HoldCo’s certificate of incorporation and bylaws do not modify these provisions of the DGCL with regard to common stock.

Generally, a business combination includes a merger, asset or stock sale, or another transaction resulting in a financial benefit to the interested stockholder. Generally, an interested stockholder is a person who, together with affiliates and associates, owns 15% or more of the corporation’s voting stock.

Indemnification of Directors and Officers

HoldCo. The DGCL provides that a corporation may indemnify its officers, directors, employees and agents against liabilities and expenses incurred in proceedings if the person acted in good faith and in a manner he or she reasonably believed to be in, or not opposed to, the best interests of the corporation and, with respect to any criminal action, had no reasonable cause to believe that the person’s conduct was unlawful. The DGCL further provides that no indemnification is available in respect of a claim as to which the person has been adjudged to be liable to the corporation, unless and only to the extent that a court determines that in view of all the circumstances, such person is fairly and reasonably entitled to indemnity for such expenses that the court deems proper. Under the DGCL, a Delaware corporation must indemnify its present or former directors and officers against expenses (including attorneys’ fees) actually and reasonably incurred to the extent that the officer or director has been successful on the merits or otherwise in defense of any action, suit or proceeding brought against him or her by reason of the fact that he or she is or was a director or officer of the corporation. The HoldCo bylaws provide that HoldCo will indemnify each person in a pending or threatened action, suit or proceeding, whether civil, criminal, administrative or investigative, by reason of the fact that he or a person of whom he is the legal representative, is or was a director or officer of HoldCo or is or was serving at the request of HoldCo as a director, officer, partner, employee or trustee of, or in a similar capacity with, another corporation, partnership, joint venture, trust or other enterprise, including service with respect to employee benefit plans, whether the basis of such proceeding is alleged action in an official capacity as a director or officer, or in any other capacity while serving as a director or officer or as otherwise described above, shall be indemnified and held harmless by HoldCo to the fullest extent authorized by the DGCL against all expenses (including attorneys’ fees), liability and loss reasonably incurred or suffered by such person in connection therewith (including, to the extent permitted by law, amounts paid in settlement actually and reasonably incurred in connection with such action, suit or proceeding, and any appeal therefrom), and such indemnification shall continue as to a person who has ceased to be a director or officer and shall inure to the benefit of his heirs, executors and administrators; provided, that, HoldCo will indemnify any such person seeking indemnity in connection with a proceeding (or part thereof) initiated by such person only if (a) such indemnification is expressly required to be made by law, (b) the proceeding (or part thereof) was authorized by the HoldCo board of directors, (c) such indemnification is provided by HoldCo, in its sole discretion, pursuant to the powers under the DGCL, or (d) the proceeding (or part thereof) is brought to establish or enforce a right to indemnification or advancement under an indemnity agreement or any other statute or law or otherwise as required under Section 145 of the DGCL. The rights hereunder shall be contract rights and shall include the right to be paid expenses incurred in defending any such proceeding in advance of its final disposition; provided, that the payment of such expenses incurred by a director or officer of HoldCo in his capacity as a director or officer (and not in any other capacity in which service was or is tendered by such person while a director or officer, including, without limitation, service to an employee benefit plan) in advance of the final disposition of such proceeding, shall be made only upon delivery to HoldCo of an

RareGen. The DLLCA provides that the limited liability company agreement may provide for indemnification of any member, manager or other person from and against any and all claims and demands whatsoever. The RareGen operating agreement provides that RareGen will indemnify each director and each person serving as an officer of RareGen, including persons who serve at RareGen’s request as directors, managers, members, partners, officers, employees, agents or trustees of another organization in which RareGen has any interest as a shareholder, member, creditor or otherwise, and their respective successors and assigns from and against any and all losses asserted against, imposed on or incurred by such person at any time, including as a result of such person’s capacity as a director or officer or employee; provided that no such indemnification shall be provided for any losses incurred as a result of such person’s willful misconduct or knowing violation of the criminal law.

Limitation on Personal Liability of Directors

HoldCo. The DGCL provides that a corporation may include in its certificate of incorporation a provision eliminating the liability of a director to the corporation or its stockholders for monetary damages for a breach of the director’s fiduciary duties, except liability for any breach of the director’s duty of loyalty to the corporation’s stockholders, for acts or omissions not in good faith or that involve intentional misconduct or knowing violation of law and for any transaction from which the director derived an improper personal benefit. The HoldCo certificate of incorporation provides that no person will be personally liable to HoldCo or its stockholders for monetary damages for breach of his or her fiduciary duty as a director of HoldCo, except for liability (i) for any breach of the director’s duty of loyalty to the HoldCo or its stockholders, (ii) for any acts or omissions not in good faith or which involve

RareGen.

The RareGen operating agreement provides that no director or officer of RareGen will be liable to RareGen or any member for any act or failure to act on behalf of RareGen which shall result in any loss or damage sustained by RareGen or to any member unless the loss or damage results from gross negligence, fraud, willful misconduct or knowing violation of the criminal law by the director or officer in question.

Preemptive Rights

HoldCo. The HoldCo stockholders have no preemptive or conversion rights or other subscription rights. Thus, if additional shares of HoldCo common stock are issued, the current holders of HoldCo common stock would own a proportionately smaller interest in a larger number of outstanding shares of common stock to the extent that they do not participate in the additional issuance.

The right of first refusal does not apply to (1) common units (and/or options, warrants or other unit purchase rights issued pursuant to such options, warrants or other rights exercisable into common units) issued or to be issued on or after the date of the operating agreement to employees, officers, directors, consultants or advisors to RareGen, pursuant to any equity compensation plan or other arrangements that are approved by the RareGen board of directors provided that the issuances permitted by this clause (1) do not exceed 10% of the outstanding units; (2) any securities issued for consideration other than cash pursuant to a merger, consolidation, acquisition or similar business combination with any non-affiliated third party approved by the RareGen board of directors; (3) units issued in connection with any unit split, dividend or recapitalization by RareGen effected on a proportionate basis across all classes or series of units; (4) any units issued upon conversion of convertible units; (5) any units or securities issued pursuant to any licensing, strategic alliance, partnership or joint venture agreement, or loan arrangement, or debt financing from a bank or similar non-affiliated financial or lending institution approved by the RareGen board of directors; and (6) any securities that are issued by RareGen to third parties (and not to members or their affiliates) pursuant to a registration statement filed under the Securities Act.

Cumulative Voting Rights

HoldCo. The DGCL allows for cumulative if it is authorized in a corporation’s certificate of incorporation. HoldCo’s certificate of incorporation does not provide for cumulative voting in the election of directors.

Dividends and Stock Repurchases

HoldCo. The DGCL provides that, subject to any restrictions in a corporation’s certificate of incorporation, dividends may be declared from the corporation’s surplus, or, if there is no surplus, from its net profits for the fiscal year in which the dividend is declared and for the preceding fiscal year. Dividends may not be declared out of net profits, however, if the corporation’s capital has been diminished to an amount less than the aggregate amount of all capital represented by the issued and outstanding stock of all classes having a preference upon the distribution of assets until the deficiency in the amount of capital represented by the issued and outstanding stock of all classes having a preference upon the distribution of assets is repaired. Furthermore, the DGCL generally provides that a corporation may redeem or repurchase its shares only if the redemption or repurchase would not impair the capital of the corporation. The HoldCo bylaws do not modify these provisions of DGCL.

Liquidia Technologies. Our amended and restated bylaws do not modify the provisions of DGCL.

RareGen. The RareGen operating agreement provides that the RareGen board of directors has the sole discretion to distribute annually (or more frequently in the board’s discretion) to the members an amount not to exceed distributable cash for such fiscal year or other period, or the net proceeds to RareGen from any financing or refinancing to the members on a pro rata basis in proportion to each member’s respective unit percentages. Additionally, unless the RareGen board of directors determines otherwise by unanimous approval of the board of directors, RareGen will make quarterly distributions to each member in an amount equal to their estimated United States federal, state and local income liabilities (including estimated income tax liabilities) arising from allocations of profits and losses of RareGen. The net proceeds (after RareGen’s payment of all expenses, indebtedness and obligations incurred in connection with a terminating capital transaction) shall be distributed in the following order and priority: (i) first, towards the satisfaction of all outstanding debts and obligations of RareGen (including to members in the priority provided by law; (ii) second, the balance to the holders of all units in proportion to their respective positive capital account balances after all allocations of profits and losses. Profits for any fiscal year or other period, other than profits from a terminating capital transaction, shall be allocated to the members on a pro rata basis in proportion to their respective unit percentages. Losses for any fiscal year or any other period, other than losses from a terminating capital transaction, shall be allocated to the members to the extent of and in proportion to their respective capital account balances and, thereafter, to the members on a pro rata basis in proportion to their respective unit percentages.

Dissenters’ or Appraisal Rights

HoldCo. The DGCL provides that a stockholder may dissent from, and receive payment in cash for, the fair value of his or her shares as appraised by the Delaware Chancery Court in the event of certain mergers and consolidations. However, stockholders do not have appraisal rights if the shares of stock they hold, at the record date for determination of stockholders entitled to vote at the meeting of stockholders to act upon the merger or consolidation, or on the record date with respect to action by written consent, are either (i) listed on a national securities exchange or designated as a national market system security on an interdealer quotation system by the National Association of Securities Dealers, Inc. or (ii) held of record by more than 2,000 stockholders. Further, no appraisal rights are available to stockholders of the surviving corporation if the mergers did not require the vote of the stockholders of the surviving corporation. Notwithstanding the foregoing, appraisal rights are available if stockholders are required by the terms of the Merger Agreement to accept for their shares anything other than: (i) shares of stock of the surviving corporation, (ii) shares of stock of another corporation that are listed on a national securities exchange, designated as a national market system security as described above, or held of record by more than 2,000 stockholders, (iii) cash instead of fractional shares of stock; or (iv) any combination of the foregoing. Appraisal rights are also available under the DGCL in certain other circumstances including in certain parent-subsidiary corporation mergers and in certain

Such record date shall not precede the date on which the resolution fixing the record date is adopted and shall not be more than 60 nor less than 10 days before the date of such meeting. If no record date is fixed by the board of directors, the record date for determining the stockholders entitled to notice of or to vote at a meeting of stockholders shall be the close of business on the day before the date on which notice is given, or, if notice is waived, the close of business on the day before the date on which the meeting is held.

Prior to effectuating a non-permitted voluntary transfer of units, RareGen has the right of first refusal to purchase all or any portion of the units offered in such transfer, the non-selling members have the right of second refusal to purchase pro rata all or a portion of the remaining units offered in such transfer and the non-selling members have a right of co-sale in any such transfer which may result in a reduction in the number of units to be sold by the selling member.

PROPOSAL 2 — APPROVAL OF THE HOLDCO 2020 INCENTIVE PLAN

General

Stockholders are being asked to approve the proposed Liquidia Corporation 2020 Long-Term Incentive Plan, which is also referred to as the HoldCo 2020 Incentive Plan in this proxy statement/prospectus. The HoldCo 2020 Incentive Plan was adopted by the HoldCo board of directors on June 28, 2020, and will become effective upon the closing date of the Merger Transaction, subject to approval by our stockholders.

Below is a summary of the principal provisions of the HoldCo 2020 Incentive Plan assuming stockholder approval, which summary is qualified in its entirety by reference to the full text of the HoldCo 2020 Incentive Plan, a copy of which is attached to this proxy statement/prospectus as Annex C.

The HoldCo 2020 Incentive Plan is substantially identical to the Liquidia Technologies, Inc. 2018 Long-Term Incentive Plan, or the Liquidia 2018 Plan. At the effective time of the Merger Transaction, (i) HoldCo will assume the Liquidia 2018 Plan, the Liquidia Technologies, Inc. 2016 Equity Incentive Plan, as amended, and the Liquidia Technologies, Inc. Stock Option Plan, which we collectively refer to herein as the Assumed Plans, and each outstanding, unexercised and unexpired stock option or restricted stock unit granted under the Assumed Plans; and (ii) the assumed options and restricted stock units will become exercisable for shares of HoldCo common stock on a one-for-one basis and remain subject to the same terms and conditions set forth in the Assumed Plans and related agreements.

No “Awards”, as defined below, will be made under the Liquidia 2018 Plan after the effective time of the Merger Transaction.

The HoldCo 2020 Incentive Plan is designed to:

•

promote the long-term financial interests and growth of HoldCo and its subsidiaries by attracting and retaining directors and employees, which include management as well as other personnel;

•

motivate management by means of growth-related incentives to achieve long-range goals; and

•

further the alignment of the interests of participants and those of HoldCo’s stockholders, through opportunities for increased stock or stock-based ownership in HoldCo.

The HoldCo 2020 Incentive Plan will remain in effect, subject to the right of HoldCo’s board of directors or Compensation Committee to amend or terminate the HoldCo 2020 Incentive Plan at any time, until the earlier of (a) the earliest date as of which all Awards granted under the HoldCo 2020 Incentive Plan have been satisfied in full or terminated and no shares of common stock approved for issuance under the HoldCo 2020 Incentive Plan remain available to be granted under new Awards, or (b) June 27, 2030. No Awards will be granted under the HoldCo 2020 Incentive Plan after such termination date. Subject to other applicable provisions of the HoldCo 2020 Incentive Plan, all Awards made under the HoldCo 2020 Incentive Plan on or before June 27, 2030, or such earlier termination of the HoldCo 2020 Incentive Plan, shall remain in effect until such Awards have been satisfied or terminated in accordance with the HoldCo 2020 Incentive Plan and the terms of such Awards.

Participation in the HoldCo 2020 Incentive Plan

All of HoldCo’s and its subsidiaries’ officers, non-employee directors, employees and consultants are eligible to participate in the HoldCo 2020 Incentive Plan.

Participation by Non-Employee Directors

Although HoldCo’s directors, including HoldCo’s independent directors, are not involved in the day-to-day running of HoldCo’s operations on a consolidated basis, they play an important role in furthering HoldCo’s business interests by contributing their experience and expertise. In particular, a number of HoldCo’s independent directors have substantial experience and expertise in pharmaceutical research and

185

TABLE OF CONTENTS

development and play an important role in helping us shape HoldCo’s business strategy. It is crucial for HoldCo to be able to attract, retain and incentivize such individuals.

It may not always be possible to quantify the services and contributions of HoldCo’s non-employee directors to HoldCo, and accordingly, it may not always be possible to compensate them fully or appropriately by increasing their directors’ fees or other cash payments. To that end, participation by non-employee directors in the HoldCo 2020 Incentive Plan will allow HoldCo to acknowledge and reward their services and contributions to HoldCo. In addition, HoldCo believes that opportunities for increased stock or stock-based ownership in HoldCo will further align the interests of its non-employee directors with the interests of its stockholders.

Plan Administration

The HoldCo 2020 Incentive Plan will be administered by the “Administrator”, as defined below, provided that no director shall participate in any deliberation or decision in respect of any stock option, stock appreciation right, stock award, stock unit, performance share, performance unit and/or other stock-based award, each, an Award, and collectively, the Awards, to be granted to him or held by him.

For the purposes of the HoldCo 2020 Incentive Plan, “Administrator” means HoldCo’s Compensation Committee, or such other committee(s) of director(s) duly appointed by HoldCo’s board of directors or Compensation Committee to administer the HoldCo 2020 Incentive Plan or delegated limited authority to perform administrative actions under the HoldCo 2020 Incentive Plan, and having such powers as shall be specified by HoldCo’s board of directors or Compensation Committee, provided, however, that at any time HoldCo’s board of directors may serve as the Administrator in lieu of or in addition to HoldCo’s Compensation Committee or such other committee(s) of director(s) to whom administrative authority has been delegated. With respect to any Award to which Section 16 of the Exchange Act applies, the Administrator shall consist of either HoldCo’s board of directors or a committee of HoldCo’s board of directors, which committee shall consist of three or more directors, each of whom is intended to be, to the extent required by Rule 16b-3 of the Exchange Act, a “non-employee director” as defined in Rule 16b-3 of the Exchange Act and an “independent director” to the extent required by the Nasdaq listing rules. Any member of the Administrator who does not meet the foregoing requirements shall abstain from any decision regarding an Award and shall not be considered a member of the Administrator to the extent required to comply with Rule 16b-3 of the Exchange Act.

The Administrator has the authority, in its sole and absolute discretion, to grant Awards under the HoldCo 2020 Incentive Plan to eligible individuals, and to take all other actions necessary or desirable to carry out the purpose and intent of the HoldCo 2020 Incentive Plan. Further, the Administrator has the authority, in its sole and absolute discretion, subject to the terms and conditions of the HoldCo 2020 Incentive Plan, to, among other things:

•

determine the eligible individuals to whom, and the time or times at which, Awards shall be granted;

•

determine the type of Awards to be granted to any eligible individual;

•

determine the number of shares of common stock to be covered by or used for reference purposes for each Award or the value to be transferred pursuant to any Award; and

•

determine the terms, conditions and restrictions applicable to each Award and any shares of common stock acquired pursuant thereto, including, without limitation, (i) the purchase price of any shares of common stock, (ii) the method of payment for shares of common stock purchased pursuant to any Award, (iii) the method for satisfying any tax withholding obligation arising in connection with any Award, including by the withholding or delivery of shares of common stock, (iv) the timing, terms and conditions of the exercisability, vesting or payout of any Award or any shares of common stock acquired pursuant thereto, (v) the performance goals applicable to any Award and the extent to which such performance goals have been attained, (vi) the time of the expiration of an Award, (vii) the effect of a participant’s Termination of Service, as defined in the HoldCo 2020 Incentive Plan, on any of the foregoing and (viii) all other terms, conditions and restrictions applicable to any Award or shares of common stock acquired pursuant thereto as the Administrator considers to be appropriate and not inconsistent with the terms of the HoldCo 2020 Incentive Plan.

TABLE OF CONTENTS

Size

A total of 1,700,000 shares of HoldCo common stock will be initially authorized and reserved for issuance under the HoldCo 2020 Incentive Plan. This reserve will automatically increase on January 1, 2021 and each subsequent anniversary through 2030, by an amount equal to the smaller of (a) 4% of the number of shares of common stock issued and outstanding on the immediately preceding December 31, or (b) an amount determined by the HoldCo board of directors. This reserve will not be increased to include any shares issuable upon exercise of options granted under an Assumed Plan that expire or terminate without having been exercised in full.

Appropriate adjustments will be made in the number of authorized shares and other numerical limits in the HoldCo 2020 Incentive Plan and in outstanding awards to prevent dilution or enlargement of participants’ rights in the event of a stock split or other change in HoldCo’s capital structure. Shares subject to awards which expire, are cancelled, forfeited, terminated unearned, settled in cash, or withheld or surrendered in payment of an exercise price or taxes will again become available for issuance under the HoldCo 2020 Incentive Plan.

Subject to adjustment as provided in the provision of the HoldCo 2020 Incentive Plan pertaining to the occurrence of certain corporate transactions, the maximum number of shares of common stock that may be issued pursuant to stock options granted under the HoldCo 2020 Incentive Plan that are intended to qualify as incentive stock options is 10,000,000.

Key Considerations in the Determination of Shares to be Authorized

In determining the number of shares to be initially authorized under the HoldCo 2020 Incentive Plan, the HoldCo Compensation Committee considered the following principal factors and information as of July 15, 2020 on which date there were 37,749,890 shares of common stock outstanding:

•

Number of Shares Available for Grant under the Liquidia 2018 Plan: As of July 15, 2020, 1,378,286 shares remained reserved and available for issuance under the Liquidia 2018 Plan.

•

Burn Rate. Burn rate measures the usage of shares of HoldCo’s stock plans as a percentage of outstanding shares. For 2019, our burn rate was 3.9%.

•

Overhang. As of July 15, 2020, 3,036,502 shares were subject to outstanding awards under the Assumed Plans resulting in an overhang of approximately 8.0%. Following the Merger Transaction, upon including the shares requested under the Holdco 2020 Incentive Plan, the overhang on a fully diluted basis would be approximately 12.5%.

When considering the number of shares to be initially reserved for the HoldCo 2020 Incentive Plan as well as the plan’s evergreen feature, the HoldCo Compensation Committee also reviewed, among other things, projected future share usage and projected future forfeitures. The projected future usage of shares for long-term incentive awards under the HoldCo 2020 Incentive Plan was reviewed under scenarios based on a variety of assumptions. The HoldCo Compensation Committee is committed to effectively managing the number of shares reserved for issuance under the HoldCo 2020 Incentive Plan while minimizing stockholder dilution.

Maximum Entitlements

The Administrator may establish compensation for directors who are not employees of HoldCo or any of its Affiliates, as defined in the HoldCo 2020 Incentive Plan, or the Non-Employee Directors, from time to time, provided that the sum of any cash compensation and the grant date fair value of Awards granted under the HoldCo 2020 Incentive Plan to a non-employee director as compensation for services as a non-employee director during any calendar year may not exceed $500,000 for an annual grant, provided however that in a non-employee’s director first year of service, compensation for services may not exceed $1 million. The Administrator may make exceptions to this limit for individual non-employee directors in extraordinary circumstances, as the Administrator may determine in its discretion, provided that the non-employee director receiving such additional compensation may not participate in the decision to award such compensation or in other compensation decisions involving non-employee director.

187

TABLE OF CONTENTS

Awards

Awards may be granted individually or in tandem with other types of Awards, concurrently with or with respect to outstanding Awards. Participants are not required to pay for the application or acceptance of Awards.

Stock Options

The Administrator may, from time to time, grant to eligible individuals Awards of stock options.

Such stock options shall be exercisable at such time or times and subject to such terms and conditions as shall be determined by the Administrator; provided, however, that, Awards of stock options may not have a term in excess of ten years unless otherwise required by applicable law.

The exercise price per share subject to a stock option granted under the HoldCo 2020 Incentive Plan shall not be less than the fair market value of one share on the date of grant of the stock option, except as provided under applicable law or with respect to stock options that are granted in substitution of similar types of awards of a company acquired by HoldCo or with which HoldCo combines (whether in connection with a corporate transaction, such as a merger, combination, consolidation or acquisition of property or stock, or otherwise) to preserve the intrinsic value of such awards.

Except as provided in the applicable award agreement or otherwise determined by the Administrator, to the extent stock options are not vested and exercisable, a participant’s stock options shall be forfeited upon his Termination of Service.

Stock Appreciation Rights

The Administrator may, from time to time, grant to eligible individuals Awards of stock appreciation rights. A stock appreciation right entitles the participant to receive, subject to the provisions of the HoldCo 2020 Incentive Plan and the applicable award agreement, a payment having an aggregate value equal to the product of (a) the excess of (i) the fair market value on the exercise date of one share over (ii) the base price per share specified in the award agreement, and (b) the number of shares of common stock specified by the stock appreciation right, or portion thereof, which is exercised. The base price per share specified in the applicable award agreement shall not be less than the lower of the fair market value on the date of grant or the exercise price of any tandem stock option to which the stock appreciation right is related, or with respect to stock appreciation rights that are granted in substitution of similar types of awards of a company acquired by HoldCo or with which HoldCo combines (whether in connection with a corporate transaction, such as a merger, combination, consolidation or acquisition of property or stock, or otherwise) such base price as is necessary to preserve the intrinsic value of such awards.

Stock appreciation rights shall be exercisable at such time or times and subject to such terms and conditions as shall be determined by the Administrator; provided, however, that stock appreciation rights granted under the HoldCo 2020 Incentive Plan may not have a term in excess of ten years unless otherwise required by applicable law.

Except as provided in the applicable award agreement or otherwise determined by the Administrator, to the extent stock appreciation rights are not vested and exercisable, a participant’s stock appreciation rights shall be forfeited upon his Termination of Service.

Stock Awards

The Administrator may, from time to time, grant to eligible individuals Awards of unrestricted stock or restricted stock, collectively, Stock Awards. For the purposes of the HoldCo 2020 Incentive Plan, “Restricted Stock” means an Award of shares of common stock that may be subject to certain transferability and other restrictions and to a risk of forfeiture, including by reason of not satisfying certain performance goals.

Restricted Stock shall be subject to such vesting, restrictions on transferability and other restrictions, if any, and risk of forfeiture as the Administrator may impose at the date of grant or thereafter. The period during which such vesting or transferability and other restrictions and/or risk of forfeiture applies, or the

188

TABLE OF CONTENTS

Restriction Period, may lapse under such circumstances, including without limitation upon the attainment of performance goals, in such installments, or otherwise, as the Administrator may determine. Subject to the provisions of the HoldCo 2020 Incentive Plan and the applicable award agreement, during the Restriction Period, the Participant shall not be permitted to sell, assign, transfer, pledge or otherwise encumber Restricted Stock.

Except to the extent restricted under the applicable award agreement, a participant granted Restricted Stock shall have all of the rights of a stockholder including, without limitation, the right to vote. Cash dividends declared payable on of common stock shall be paid, with respect to outstanding Restricted Stock, either as soon as practicable following the dividend payment date or deferred for payment to such later date as determined by the Administrator, and shall be paid in cash or as unrestricted shares of common stock having a fair market value equal to the amount of such dividends or may be reinvested in additional shares of Restricted Stock as determined by the Administrator; provided, however, that dividends declared payable on Restricted Stock granted as a Performance Award shall be held by HoldCo and made subject to forfeiture at least until achievement of the applicable performance goal relating to such shares of Restricted Stock. Shares of common stock distributed in connection with a stock split or stock dividend, and other property distributed as a dividend, shall be subject to restrictions and a risk of forfeiture to the same extent as the Restricted Stock with respect to which such shares of common stock or other property have been distributed.

Except as provided in the applicable award agreement, upon termination of service during the applicable Restriction Period, Restricted Stock and any accrued but unpaid dividends that are at that time subject to restrictions shall be forfeited; provided that the Administrator may provide, by rule or regulation or in any Award Agreement, or may determine in any individual case, that restrictions or forfeiture conditions relating to Restricted Stock will be waived in whole or in part in the event of terminations resulting from specified causes, and the Administrator may in other cases waive in whole or in part the forfeiture of Restricted Stock.

Stock Units

The Administrator may, from time to time, grant to eligible individuals Awards of unrestricted stock units or Restricted Stock Units. For the purposes of the HoldCo 2020 Incentive Plan, “Restricted Stock Unit” means a right granted to a participant to receive shares of common stock or cash at the end of a specified deferral period, which right may be conditioned on the satisfaction of certain requirements, including the satisfaction of certain performance goals.

Restricted Stock Units shall be subject to such vesting, risk of forfeiture and/or payment provisions as the Administrator may impose at the date of grant. The Restriction Period to which such vesting and/or risk of forfeiture applies may lapse under such circumstances, including without limitation upon the attainment of performance goals, in such installments, or otherwise, as the Administrator may determine.

Until shares of common stock are issued to the participant in settlement of stock units, the participant shall not have any rights of a stockholder with respect to the stock units or the shares of common stock issuable thereunder. The Administrator may grant the participant the right to dividend equivalents on stock units, on a current, reinvested and/or restricted basis, subject to such terms as the Administrator may determine; provided, however, that dividend equivalents declared payable on stock units granted as a Performance Award shall rather than be paid on a current basis, be accrued and made subject to forfeiture at least until achievement of the applicable performance goal relating to such stock units.

Performance Shares and Performance Units

An award of Performance Shares, as that term is used in the HoldCo 2020 Incentive Plan, refers to shares of HoldCo common stock or stock units that are expressed in terms of HoldCo common stock, the issuance, vesting, lapse of restrictions or payment of which is contingent on performance as measured against predetermined objectives over a specified performance period. An award of Performance Units, as that term is used in the HoldCo 2020 Incentive Plan, refers to dollar-denominated units valued by reference to designated criteria established by the administrator, other than HoldCo common stock, whose issuance, vesting, lapse of restrictions or payment is contingent on performance as measured against predetermined objectives over a specified performance period. The applicable award agreement will specify whether Performance Shares and Performance Units will be settled or paid in cash or shares of HoldCo common

189

TABLE OF CONTENTS

stock or a combination of both, or will reserve to the administrator or the participant the right to make that determination prior to or at the payment or settlement date.

The Administrator will, prior to or at the time of grant, condition the grant, vesting or payment of, or lapse of restrictions on, an award of Performance Shares or Performance Units upon (A) the attainment of performance goals during a performance period or (B) the attainment of performance goals and the continued service of the participant. The length of the performance period, the performance goals to be achieved during the performance period, and the measure of whether and to what degree such performance goals have been attained will be conclusively determined by the Administrator in the exercise of its absolute discretion. Performance goals may include minimum, maximum and target levels of performance, with the size of the award or payout of Performance Shares or Performance Units or the vesting or lapse of restrictions with respect thereto based on the level attained. An award of Performance Shares or Performance Units will be settled as and when the award vests or at a later time specified in the award agreement or in accordance with an election of the participant, if the Administrator so permits, that meets the requirements of Section 409A.

Performance goals applicable to performance-based awards may be awarded based on performance metrics to be attained within a predetermined performance period as they may apply to an individual, one or more business units, divisions, or affiliates, or on a company-wide basis, and in absolute terms, relative to a base period, or relative to the performance of one or more comparable companies, peer groups, or an index covering multiple companies.

The Administrator may, in its discretion, adjust the performance goals applicable to any awards to reflect any unusual or non-recurring events and other extraordinary items, impact of charges for restructurings, discontinued operations and the cumulative effects of accounting or tax changes.

Other Stock-Based Awards

The Administrator may, from time to time, grant to eligible individuals Awards in the form of Other Stock-Based Awards. For the purposes of the HoldCo 2020 Incentive Plan, “Other Stock-Based Award” means an Award of shares of common stock or any other Award that is valued in whole or in part by reference to, or that is otherwise based upon, shares of common stock, including without limitation dividend equivalents and convertible debentures.

Adjustment Events

In the event of a merger, consolidation, rights offering, statutory share exchange or similar event affecting HoldCo, each, a Corporate Event, or a stock dividend, stock split, reverse stock split, separation, spinoff, reorganization, extraordinary dividend of cash or other property, share combination or subdivision or recapitalization or similar event affecting the capital structure of HoldCo, each, a Share Change, that occurs at any time after the effective date of the HoldCo 2020 Incentive Plan (including any such Corporate Event or Share Change that occurs after such adoption and coincident with or prior to the effective date of the HoldCo 2020 Incentive Plan), the Administrator shall make equitable and appropriate substitutions or proportionate adjustments to (a) the aggregate number and kind of shares of common stock or other securities on which Awards under the HoldCo 2020 Incentive Plan may be granted to eligible individuals, (b) the maximum number of shares of common stock or other securities with respect to which Awards may be granted during any one calendar year to any individual, (c) the maximum number of shares of common stock or other securities that may be issued with respect to incentive stock options granted under the HoldCo 2020 Incentive Plan, (d) the number of shares of common stock or other securities covered by each outstanding Award and the exercise price, base price or other price per share, if any, and other relevant terms of each outstanding Award and (e) all other numerical limitations relating to Awards, whether contained in the HoldCo 2020 Incentive Plan or in award agreements; provided, however, that any fractional shares resulting from any such adjustment shall be eliminated and that no such adjustment shall be made if as a result, the participant receives a benefit that a stockholder does not receive and any adjustment (except in relation to a capitalization issue) must be confirmed in writing by the auditors of HoldCo (acting as experts and not as arbitrators) to be, in their opinion, fair and reasonable.

190

TABLE OF CONTENTS

In the case of Corporate Events, the Administrator may make such other adjustments to outstanding Awards as it determines to be appropriate and desirable, which adjustments may include, without limitation, (a) the cancellation of outstanding Awards in exchange for payments of cash, securities or other property or a combination thereof having an aggregate value equal to the value of such Awards, as determined by the Administrator in its sole discretion (it being understood that in the case of a Corporate Event with respect to which stockholders receive consideration other than publicly traded equity securities of the ultimate surviving entity, any such determination by the Administrator that the value of a stock option or stock appreciation right shall for this purpose be deemed to equal the excess, if any, of the value of the consideration being paid for each share of common stock pursuant to such Corporate Event over the exercise price or base price of such stock option or stock appreciation right shall conclusively be deemed valid and that any stock option or stock appreciation right may be cancelled for no consideration upon a Corporate Event if its exercise price or base price equals or exceeds the value of the consideration being paid for each share of common stock pursuant to such Corporate Event), (b) the substitution of securities or other property (including, without limitation, cash or other securities of our company and securities of entities other than our company) for the shares of common stock subject to outstanding Awards and (c) the substitution of equivalent awards, as determined in the sole discretion of the Administrator, of the surviving or successor entity or a parent thereof; provided, however, that no such adjustment shall be made if as a result, the participant receives a benefit that a stockholder does not receive and any adjustment (except in relation to a capitalization issue) must be confirmed in writing by the auditors of HoldCo (acting as experts and not as arbitrators) to be, in their opinion, fair and reasonable.

Change in Control

In the event of a change in control, as defined in the HoldCo 2020 Incentive Plan, of HoldCo, outstanding awards will terminate upon the effective time of the change in control unless provision is made for the continuation, assumption or substitution of awards by the surviving or successor entity or its parent. Unless an award agreement says otherwise, the following will occur with respect to awards that terminate in connection with a change in control of HoldCo:

•

stock options and stock appreciation rights will become fully exercisable and holders of these awards will be permitted immediately before the change in control to exercise them;

•

restricted stock and stock units with time-based vesting (i.e., not subject to achievement of performance goals) will become fully vested immediately before the change in control, and stock units will be settled as promptly as is practicable in accordance with applicable law; and

•

performance shares and units that vest based on the achievement of performance goals will vest as if the performance goal for the unexpired performance period had been achieved at the target level; and the performance units will be settled as promptly as is practicable in accordance with applicable law.

HoldCo 2020 Incentive Plan Amendments

HoldCo’s board of directors or Compensation Committee may amend, alter or discontinue the HoldCo 2020 Incentive Plan, but no amendment, alteration or discontinuation shall be made which would materially impair the rights of a participant with respect to a previously granted Award without such participant’s consent, except such an amendment made to comply with applicable law or rule of any securities exchange or market on which shares of HoldCo common stock are listed or admitted for trading or to prevent adverse tax or accounting consequences to HoldCo or the participant.

HoldCo’s board of directors or Compensation Committee may, at any time, modify and/or alter any or all of the provisions of the HoldCo 2020 Incentive Plan, except that no modification or alternation of any provision shall be made to the advantage of participants except with the prior approval of stockholders a stockholders’ meeting to the extent such amendment requires stockholders’ approval under the applicable provisions of the applicable listing exchange rule, including but not limited to (a) materially expanding the eligibility for participation in the HoldCo 2020 Incentive Plan, (b) materially increasing the number of shares of common stock which may be issued under the HoldCo 2020 Incentive Plan or to a participant, (c) eliminating or modifying the prohibition set forth in the HoldCo 2020 Incentive Plan on repricing of

191

TABLE OF CONTENTS

stock options and stock appreciation rights, (d) lengthening the maximum term or lowering the minimum exercise price or base price permitted for stock options and stock appreciation rights, (e) modifying the prohibition on the issuance of reload or replenishment options or (f) materially increasing the benefits accruing to participants under the HoldCo 2020 Incentive Plan.

Amendment of Awards

The Administrator may unilaterally amend the terms of any Award theretofore granted, but no such amendment shall materially impair the rights of any participant with respect to an Award without the participant’s consent, except such an amendment made to cause the HoldCo 2020 Incentive Plan or Awards thereunder to comply with applicable law, applicable rule of any securities exchange on which shares of HoldCo common stock are listed or admitted for trading, or to prevent adverse tax or accounting consequences for the participant or HoldCo or any of its affiliates. For purposes of the foregoing sentence, an amendment to an Award that results in a change in the tax consequences of the Award to the participant shall not be considered to be a material impairment of the rights of the participant and shall not require the participant’s consent.

Required Vote; Recommendation of Board of Directors

To approve Proposal 2, if a quorum is present or represented by proxy at the special meeting, stockholders holding a majority of our common stock present or represented by proxy at the special meeting and entitled to vote on the matter must vote “FOR” the proposal, meaning that the votes cast by our stockholders “FOR” the approval of the proposal must exceed the number of votes cast “AGAINST” the approval of the proposal. If a stockholder votes to “ABSTAIN,” it has the same effect as a vote “AGAINST.” Broker non-votes will not be considered as votes cast “FOR” or “AGAINST” this proposal and will therefore have no effect on the outcome of the vote. If no vote is specified on the proxy and in the absence of directions to the contrary, the shares will be voted “FOR” the HoldCo 2020 Incentive Plan.

OUR BOARD OF DIRECTORS RECOMMENDS THAT OUR STOCKHOLDERS VOTE “FOR” THE APPROVAL OF THE LIQUIDIA CORPORATION 2020 LONG-TERM INCENTIVE PLAN.

PROPOSAL 3 — APPROVAL OF THE HOLDCO 2020 ESPP

General

Our stockholders are being asked to approve the proposed Liquidia Corporation 2020 Employee Stock Purchase Plan, which is also referred to as the HoldCo 2020 ESPP in this proxy statement/prospectus. The HoldCo 2020 ESPP was adopted by the HoldCo board of directors on June 28, 2020, and will become effective upon the closing date of the Merger Transaction, subject to approval by our stockholders.

Summary

Below is a summary of the principal provisions of the HoldCo 2020 ESPP assuming stockholder approval, which summary is qualified in its entirety by reference to the full text of the HoldCo 2020 ESPP, a copy of which is attached to this proxy statement/prospectus as Annex D. Our stockholders are urged to read the actual text of the HoldCo 2020 ESPP in its entirety.

The HoldCo 2020 ESPP is substantially identical to the Liquidia Technologies, Inc. 2018 ESPP, or the Liquidia ESPP. At the effective time of the Merger Transaction, the Liquidia ESPP will be terminated and all shares registered on Form S-8 thereunder will be deregistered and a new Form S-8 will be filed to register the shares issuable under the HoldCo 2020 ESPP.

Overview

A total of 300,000 shares of HoldCo common stock are available for sale under the HoldCo 2020 ESPP. In addition, the HoldCo 2020 ESPP provides for annual increases in the number of shares available for issuance under the HoldCo 2020 ESPP on January 1, 2021 and each subsequent anniversary through 2030, equal to the smallest of:

•

1.0% of the outstanding shares of HoldCo common stock on the immediately preceding December 31;

•

150,000 shares; or

•

such other amount as may be determined by the HoldCo board of directors.

Appropriate adjustments will be made in the number of authorized shares and in outstanding purchase rights to prevent dilution or enlargement of participants’ rights in the event of a stock split or other change in HoldCo’s capital structure. Shares subject to purchase rights which expire or are cancelled will again become available for issuance under the HoldCo 2020 ESPP.

The HoldCo Compensation Committee will administer the HoldCo 2020 ESPP and have full authority to interpret the terms of the HoldCo 2020 ESPP. The HoldCo 2020 ESPP provides, subject to certain limitations, for indemnification by HoldCo of any director, officer or employee against all reasonable expenses, including attorneys’ fees, incurred in connection with any legal action arising from such person’s action or failure to act in administering the HoldCo 2020 ESPP.

All of HoldCo’s employees, including HoldCo’s named executive officers, are eligible to participate if they are customarily employed by HoldCo or a subsidiary of HoldCo for at least 20 hours per week and more than five months in any calendar year. Non-employee directors are not eligible to participate in the HoldCo 2020 ESPP. Following the closing of the Merger Transaction, HoldCo is expected to have approximately 75 full-time employees. However, an employee may not be granted rights to purchase stock under the HoldCo 2020 ESPP if such employee:

•

TABLE OF CONTENTS

The HoldCo 2020 ESPP is intended to qualify under Section 423 of the Code and the HoldCo 2020 ESPP shall be so construed. The HoldCo 2020 ESPP will typically be implemented through two consecutive six-month offering periods. The offering periods generally start on or about March 1st and September 1st of each year after an enrollment period. The HoldCo Compensation Committee may, in its discretion, modify the terms of future offering periods, including establishing offering periods of up to 27 months and providing for multiple purchase dates.

The HoldCo 2020 ESPP permits participants to purchase common stock through payroll deductions of up to 20.0% of their eligible compensation, which includes a participant’s regular and recurring straight time gross earnings and payments for overtime and shift premiums, but exclusive of sign-on bonuses, annual or other incentive bonuses, commissions, profit-sharing distributions or other incentive-type payments, any contributions made by HoldCo on the participant’s behalf to any employee benefit or welfare plan now or hereafter established (other than amounts deferred pursuant to Section 401(k) or Section 125 of the Code), payments in lieu of notice, payments pursuant to a severance agreement, termination pay, moving allowances, relocation payments, or any amounts directly or indirectly paid pursuant to the HoldCo 2020 ESPP or any other stock purchase, stock option or other stock-based compensation plan, or similar types of compensation.

Amounts deducted and accumulated from participant compensation are used to purchase shares of HoldCo common stock at the end of each offering period. Under the terms of the HoldCo 2020 ESPP, the purchase price of the shares may be 85.0% of the lower of the fair market value of HoldCo common stock on the first trading day of the offering period or on the last day of the offering period; provided, however, that as a default the purchase price of the shares will be 85.0% of the fair market value of HoldCo common stock on the last day of the offering period. Participants may end their participation at any time during an offering period and will be paid their accrued payroll deductions that have not yet been used to purchase shares of common stock. Participation ends automatically upon termination of employment with HoldCo.

Each participant in any offering will have an option to purchase for each full month contained in the offering period a number of shares which shall be the lesser of (i) the number of shares determined by dividing $2,083.33 by the fair market value of a share of HoldCo common stock on the first day of the offering period or (ii) 200 shares, and except as limited in order to comply with Section 423 of the Code. Prior to the beginning of any offering period, the HoldCo Compensation Committee, as administrator of the HoldCo 2020 ESPP, may alter the maximum number of shares that may be purchased by any participant during the offering period or specify a maximum aggregate number of shares that may be purchased by all participants in the offering period. If insufficient shares remain available under the plan to permit all participants to purchase the number of shares to which they would otherwise be entitled, the administrator will make a pro rata allocation of the available shares. Any amounts withheld from participants’ compensation in excess of the amounts used to purchase shares will be refunded, without interest.

A participant may not transfer rights granted under the HoldCo 2020 ESPP other than by will, the laws of descent and distribution or as otherwise provided under the HoldCo 2020 ESPP as described below.

As further discussed below, in the event of a change in control, an acquiring or successor corporation may assume HoldCo’s rights and obligations under outstanding purchase rights or substitute substantially equivalent purchase rights. If the acquiring or successor corporation does not assume or substitute for outstanding purchase rights, then the purchase date of the offering periods then in progress will be accelerated to a date prior to the change in control.

The HoldCo 2020 ESPP will continue in effect until terminated by the HoldCo Compensation Committee. The Compensation HoldCo Committee has the authority to amend, suspend or terminate the HoldCo 2020 ESPP at any time.

Purpose

The purpose of the HoldCo 2020 ESPP is to advance the interests of HoldCo and its stockholders by providing an incentive to attract, retain and reward HoldCo’s or its subsidiaries’ eligible employees and by motivating such persons to contribute to the growth and profitability of HoldCo. The HoldCo 2020 ESPP

194

TABLE OF CONTENTS

provides such eligible employees with an opportunity to acquire a proprietary interest in HoldCo through the purchase of common stock.

Valuation

On , 2020 the Record Date for the special meeting, the fair market value per share of our common stock was $ which was the closing price per share of our common stock on such date.

New Plan Benefits

While all of the employees employed by HoldCo and its subsidiaries for at least 20 hours per week who work more than five months in any calendar year will be eligible to participate in the HoldCo 2020 ESPP and could purchase as much $25,000 worth of HoldCo common stock in a particular year, the actual amount or value of shares purchased by any given employee or group of employees is not determinable because it depends on the elections of each employee who chooses to participate. Therefore, it is not possible to determine the benefits that will be received in the future by participants in the HoldCo 2020 ESPP or the benefits that would have been received by such participants if the HoldCo 2020 ESPP had been in effect in the year ended December 31, 2019. Therefore, a New Plan Benefits table has not been provided.

Participant Withdrawal or Termination

A participant may withdraw from the HoldCo 2020 ESPP by signing and delivering to HoldCo’s office or representative designated by HoldCo a written or electronic notice of withdrawal on a form provided by HoldCo for this purpose. Such withdrawal may be elected at any time prior to the end of an offering period; provided, however, that if a participant withdraws from the HoldCo 2020 ESPP after a purchase date, the withdrawal shall not affect shares of common stock acquired by the participant on such purchase date. A participant who voluntarily withdraws from the HoldCo 2020 ESPP is prohibited from resuming participation in the HoldCo 2020 ESPP in the same offering from which he or she withdrew, but may participate in any subsequent offering by again satisfying the requirements of the HoldCo 2020 ESPP. HoldCo may impose, from time to time, a requirement that the notice of withdrawal from the HoldCo 2020 ESPP be on file with HoldCo’s office or representative designated by HoldCo for a reasonable period prior to the effectiveness of the participant’s withdrawal.

Upon a participant’s voluntary withdrawal from the HoldCo 2020 ESPP, the participant’s accumulated HoldCo 2020 ESPP account balance which has not been applied toward the purchase of shares of common stock shall be refunded to the participant as soon as practicable after the withdrawal, without the payment of any interest, and the participant’s interest in the HoldCo 2020 ESPP and the offering shall terminate. Such amounts to be refunded may not be applied to any other offering under the HoldCo 2020 ESPP.

Change in Control

In the event of a “Change in Control” (as defined in the HoldCo 2020 ESPP) of HoldCo, the surviving, continuing, successor, or purchasing corporation or parent thereof, as the case may be, or the “Acquiring Corporation”, may, without the consent of any participant, assume or continue our rights and obligations under outstanding purchase rights or substitute substantially equivalent purchase rights for the Acquiring Corporation’s stock. If the Acquiring Corporation elects not to assume, continue or substitute for the outstanding purchase rights, the purchase date of the then current offering period shall be accelerated to a date before the date of the Change in Control specified by the HoldCo Compensation Committee, but the number of shares of common stock subject to outstanding purchase rights shall not be adjusted. All purchase rights which are neither assumed or continued by the Acquiring Corporation in connection with the Change in Control nor exercised as of the date of the Change in Control shall terminate and cease to be outstanding effective as of the date of the Change in Control.

Amendment or Termination of the ESPP

The HoldCo Compensation Committee, as administrator of the HoldCo 2020 ESPP, may at any time amend, suspend or terminate the HoldCo 2020 ESPP, except that (a) no such amendment, suspension or termination shall affect purchase rights previously granted under the HoldCo 2020 ESPP unless expressly

195

TABLE OF CONTENTS

provided by the HoldCo Compensation Committee, and (b) no such amendment, suspension or termination may adversely affect a purchase right previously granted under the HoldCo 2020 ESPP without the consent of the participant, except to the extent permitted by the HoldCo 2020 ESPP or as may be necessary to qualify the HoldCo 2020 ESPP as an employee stock purchase plan pursuant to Section 423 of the Code or to comply with any applicable law, regulation or rule. In addition, an amendment to the HoldCo 2020 ESPP must be approved by the stockholders of HoldCo within 12 months of the adoption of such amendment if such amendment would authorize the sale of more shares than are then authorized for issuance under the HoldCo 2020 ESPP or would change the definition of the corporations that may be designated by the HoldCo Compensation Committee as “Participating Companies” (as defined in the HoldCo 2020 ESPP). Notwithstanding the foregoing, in the event that the HoldCo Compensation Committee determines that continuation of the HoldCo 2020 ESPP or an offering would result in unfavorable financial accounting consequences to HoldCo, the HoldCo Compensation Committee may, in its discretion and without the consent of any participant, including with respect to an offering period then in progress: (i) terminate the HoldCo 2020 ESPP or any offering period, (ii) accelerate the purchase date of any offering period, (iii) reduce the discount or the method of determining the purchase price in any offering period (e.g., by determining the purchase price solely on the basis of the “Fair Market Value” (as defined in the HoldCo 2020 ESPP) on the purchase date), (iv) reduce the maximum number of shares of common stock that may be purchased in any offering period, or (v) take any combination of the foregoing actions.

Federal Income Tax Consequences Relating to the HoldCo 2020 ESPP

The following is a summary of the principal U.S. federal income tax consequences generally applicable to awards made to a U.S. employee under the HoldCo 2020 ESPP. It does not describe all federal tax consequences under the HoldCo 2020 ESPP, nor does it describe state or local tax consequences.

The HoldCo 2020 ESPP is intended to qualify as an “employee stock purchase plan” under Section 423 of the Code. Amounts withheld from pay under the HoldCo 2020 ESPP are taxable income to participating employees in the year in which the amounts otherwise would have been received, but the participating employees will not be required to recognize additional income for federal income tax purposes either at the time the employee is deemed to have been granted a right to purchase common stock (on the first day of an offering period) or when the right to purchase common stock is exercised (on the last day of the purchase period).

If the participating employee holds the common stock purchased under the HoldCo 2020 ESPP for at least two years after the first day of the offering period in which the common stock was acquired, or the “Grant Date”, and for at least one year after the date the common stock is purchased, when the participating employee disposes of the common stock, he or she will recognize as ordinary income an amount equal to the lesser of:

•

the excess of the fair market value of the common stock on the date of disposition over the price paid for the common stock; or

•

the fair market value of the common stock on the Grant Date multiplied by the discount percentage for stock purchases under the HoldCo 2020 ESPP. HoldCo may choose 15% or a lesser discount percentage, including a zero discount percentage.

If the participating employee disposes of the common stock within two years after the Grant Date or within one (1) year after the date the common stock is purchased, he or she will recognize ordinary income equal to the fair market value of the common stock on the last day of the purchase period in which the common stock was acquired less the amount paid for the common stock. The ordinary income recognition pertains to any disposition of common stock acquired under the HoldCo 2020 ESPP (such as by sale, exchange or gift).

Upon disposition of the common stock acquired under the HoldCo 2020 ESPP, any gain realized in excess of the amount reported as ordinary income will be reportable by the participating employee as a capital gain, and any loss will be reportable as a capital loss. Amounts required to be reported as ordinary income on the disposition of the common stock may be added to the purchase price in determining any

196

TABLE OF CONTENTS

remaining capital gain or loss. Capital gain or loss will be long-term if the employee has satisfied the two-year holding period requirement described above or, in any event, if the employee has held the common stock for at least one year. Otherwise, the capital gain or loss will be short-term.

If the participating employee satisfies the two-year holding period for common stock purchased under the HoldCo 2020 ESPP, HoldCo will not receive any deduction for federal income tax purposes with respect to that common stock or the right under which it was purchased. If the employee does not satisfy the two-year holding period, HoldCo will be entitled to a deduction in an amount equal to the amount that is considered ordinary income. Otherwise, the HoldCo 2020 ESPP has no tax effect on HoldCo.

If the exercise of a Purchase Right does not constitute an exercise pursuant to an “employee stock purchase plan” under section 423 of the Code, the exercise of the Purchase Right will be treated as the exercise of a nonstatutory stock option. The participant would therefore recognize ordinary income on the purchase date equal to the excess of the fair market value of the shares acquired over the purchase price. Such income is subject to withholding of income and employment taxes. Any gain or loss recognized on a subsequent sale of the shares, as measured by the difference between the sale proceeds and the sum of (i) the purchase price for such shares and (ii) the amount of ordinary income recognized on the exercise of the Purchase Right, will be treated as a capital gain or loss, as the case may be.

Required Vote; Recommendation of Board of Directors

To approve Proposal 3, if a quorum is present or represented by proxy at the special meeting, stockholders holding a majority of our common stock present or represented by proxy at the special meeting and entitled to vote on the matter must vote “FOR” the proposal, meaning that the votes cast by the stockholders “FOR” the approval of the proposal must exceed the number of votes cast “AGAINST” the approval of the proposal. If a stockholder votes to “ABSTAIN,” it has the same effect as a vote “AGAINST.” Broker non-votes will not be considered as votes cast “FOR” or “AGAINST” this proposal and will therefore have no effect on the outcome of the vote. If no vote is specified on the proxy and in the absence of directions to the contrary, the shares will be voted “FOR” the HoldCo 2020 ESPP.

OUR BOARD OF DIRECTORS RECOMMENDS THAT OUR STOCKHOLDERS VOTE “FOR” THE APPROVAL OF THE LIQUIDIA CORPORATION 2020 EMPLOYEE STOCK PURCHASE PLAN.

PROPOSAL 4 — HOLDCO 2020 AUDITOR RATIFICATION

HoldCo’s Audit Committee has appointed PricewaterhouseCoopers LLP, which is Liquidia Technologies’ auditor, as the HoldCo’s independent registered public accounting firm for the year ending December 31, 2020. In connection with this appointment, PricewaterhouseCoopers LLP will examine and report to stockholders on the financial statements of HoldCo for 2020 following completion of the Merger Transaction.

Although stockholder ratification of the appointment of HoldCo’s independent registered public accounting firm is not required by HoldCo’s bylaws or otherwise, we have put this proposal before our stockholders because we believe that seeking stockholders’ ratification of the Audit Committee’s appointment of HoldCo’s independent registered public accounting firm is good corporate practice. This vote is only advisory, however, because HoldCo’s Audit Committee has the sole authority to retain and dismiss HoldCo’s independent registered public accounting firm. If the appointment of PricewaterhouseCoopers LLP is not ratified, the Audit Committee will evaluate the basis for the stockholders’ vote when determining whether to continue the firm’s engagement. Even if the appointment is ratified, the Audit Committee in its sole discretion may direct the appointment of a different independent registered public accounting firm at any time if it determines that such a change would be in the best interests of HoldCo and its stockholders following completion of the Merger Transaction.

Representatives of PricewaterhouseCoopers LLP are expected to be virtually present at the special meeting and are expected to be available to respond to appropriate questions from stockholders. They also will have the opportunity to make a statement if they desire to do so.

Principal Accounting Fees and Services

The following table summarizes the aggregate fees billed for professional services rendered to us by PricewaterhouseCoopers LLP, our registered independent public accounting firm, during the fiscal years ended December 31, 2018 and 2019. A description of these fees and services follows the table.

	2018			2019
Audit Fees(1)		$	1,128,332		$	648,008
Audit-Related Fees(2)		$	37,840		$	—
Tax Fees(3)			—		$	—
All Other Fees(4)		$	2,768		$	2,768
TOTAL		$	1,168,940		$	650,776

(1)

Audit fees consist of fees billed for the audit of our annual financial statements, the review of our interim financial statements and related services that are normally provided in connection with public offerings, including the registration statement for our initial public offering in the third quarter of 2018, our follow-on public offering in the first quarter of 2019, our “at-the-market” sales agreement entered into in August 2019 and our private offering of common stock in December 2019.

(2)

Audit-related fees consist of fees billed for assurance and related services that are reasonably related to the performance of the audit or review of the Company’s financial statements and are not reported under “Audit Fees.” For 2018, fees for the review of our initial assessment of ASC 606, Revenue from Contracts with Customers, comprise substantially all of such fees.

(3)

Tax fees consist of fees billed for services including, but not limited to, assistance with tax compliance, tax advice and tax planning. There were no such fees in 2018 or 2019.

(4)

This category includes fees billed for the use of a research tool and automated disclosure checklist.

HoldCo’s Audit Committee has considered whether the provision of these services by PricewaterhouseCoopers LLP is compatible with maintaining the independence of PricewaterhouseCoopers LLP. Further, pursuant to the Audit Committee’s pre-approval policies and procedures described below, all of the services provided by PricewaterhouseCoopers LLP in 2018 and 2019 were approved in advance in accordance with Liquidia Technologies’ Audit Committee’s pre-approval policies and procedures described

198

TABLE OF CONTENTS

below. The Liquidia Technologies’ Audit Committee did not rely on the waiver of pre-approval procedures permitted with respect to de minimis non-audit services under the applicable rules of the SEC for its approval of any of the services provided by PricewaterhouseCoopers LLP in 2018 and 2019.

Pre-Approval of Audit and Permissible Non-Audit Services

HoldCo’s Audit Committee requires pre-approval of all audit and non-audit services in one of two methods. Under the first method, the engagement to render the services would be entered into pursuant to pre-approval policies and procedures established by the Audit Committee, provided (i) the policies and procedures are detailed as to the services to be performed, (ii) the Audit Committee is informed of each service, and (iii) such policies and procedures do not include delegation of the Audit Committee’s responsibilities under the Exchange Act, to the Company’s management. Under the second method, the engagement to render the services would be presented to and pre-approved by the Audit Committee (subject to the de minimis exceptions for non-audit services described in Section 10A(i)(1)(B) of the Exchange Act that are approved by the Audit Committee prior to the completion of the audit). The Audit Committee has the authority to delegate to one or more members of the Audit Committee the authority to grant pre-approvals of audit and permissible non-audit services by the independent registered public accounting firm, provided that all pre-approvals by such Audit Committee members must be presented to the full Audit Committee at its next scheduled meeting. The Audit Committee considers, among other things, whether the provision of such audit or non-audit services is consistent with applicable regulations regarding maintaining auditor independence, whether the provision of such services would impair the independent register public accounting firm’s independence and whether the independent registered public accounting firm are best positioned to provide the most effective and efficient service.

Required Vote; Recommendation of Board of Directors

To approve Proposal 4, if a quorum is present or represented by proxy at the meeting, stockholders holding a majority of our common stock present or represented by proxy at the special meeting and entitled to vote on the matter must vote “FOR” the proposal, meaning that the votes cast by the stockholders “FOR” the approval of the proposal must exceed the number of votes cast “AGAINST” the approval of the proposal. If a stockholder votes to “ABSTAIN,” it has the same effect as a vote “AGAINST.” As Proposal 4 is a routine matter, broker non-votes will not occur with respect to this proposal. If no vote is specified on the proxy and in the absence of directions to the contrary, the shares will be voted “FOR” the ratification of the appointment of HoldCo’s independent auditor.

OUR BOARD OF DIRECTORS RECOMMENDS THAT OUR STOCKHOLDERS VOTE “FOR” THE RATIFICATION OF HOLDCO’S AUDIT COMMITTEE’S APPOINTMENT OF PRICEWATERHOUSECOOPERS LLP AS HOLDCO’S INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM FOR 2020.

PROPOSAL 5 — GRANT OF DISCRETIONARY AUTHORITY TO THE LIQUIDIA BOARD OF
DIRECTORS TO ADJOURN OR POSTPONE THE SPECIAL MEETING

General

At the special meeting of our stockholders, and any adjournment or postponement of the special meeting, we stockholders will be asked to consider and vote upon a proposal to grant discretionary authority to our board of directors to adjourn or postpone the special meeting to a later date, if necessary, to solicit additional proxies if there are insufficient votes in favor of Proposals 1, 2, 3 or 4.

Proposal

If at our special meeting on , 2020, the number of shares of our common stock entitled to vote and voting in favor of the proposal to adopt the Merger Agreement and approve the Liquidia Merger, the proposal to approve the HoldCo 2020 Incentive Plan and the HoldCo 2020 ESPP, and the proposal to ratify HoldCo’s auditors for 2020, which are Proposals 1 – 4, respectively, is insufficient under applicable law and our organizational documents to approve such proposal, our board of directors intends to move to adjourn the special meeting in order to solicit additional proxies in favor of the proposal(s).

In this Proposal 5, we are asking our stockholders to authorize the holder of any proxy solicited by our board of directors to vote in favor of granting the discretionary authority to our board of directors to adjourn or postpone our special meeting, and any later adjournments, in order to enable our board of directors to solicit additional proxies in favor of Proposal 1, Proposal 2, Proposal 3 or Proposal 4. If our stockholders approve this Proposal 5, our board of directors could adjourn or postpone the special meeting, and any adjourned session of the special meeting, and use the additional time to solicit additional proxies in favor of Proposal 1, Proposal 2, Proposal 3 or Proposal 4, including the solicitation of proxies from our stockholders that have previously voted against Proposal 1, Proposal 2, Proposal 3 or Proposal 4. Among other things, approval of this Proposal 5 could mean that, even if we has received proxies representing a sufficient number of votes against Proposal 1, Proposal 2, Proposal 3 or Proposal 4 to defeat them, our board of directors could adjourn the special meeting without a vote on Proposal 1, Proposal 2, Proposal 3 or Proposal 4 and seek during that period to convince the holders of those shares to change their votes to vote in favor of Proposal 1, Proposal 2, Proposal 3 or Proposal 4, as the case may be.

Our board of directors believes that if the number of shares of our common stock present or represented at the special meeting and voting in favor of Proposal 1, Proposal 2, Proposal 3 or Proposal 4 is insufficient to approve such proposals, it is in the best interests of our stockholders to enable our board of directors, for a limited period of time in the discretion of our board of directors, to continue to seek to obtain a sufficient number of additional votes in favor of one or more such proposals to bring about their approval.

Required Vote; Recommendation of Board of Directors

To approve this Proposal 5, regardless of whether a quorum is present or represented by proxy at the special meeting, stockholders holding a majority of our common stock present or represented by proxy at the special meeting and entitled to vote on the matter must vote “FOR” the proposal, meaning that the votes cast by the stockholders “FOR” the approval of the proposal must exceed the number of votes cast “AGAINST” the approval of the proposal. If a stockholder votes to “ABSTAIN,” it has the same effect as a vote “AGAINST.” Broker non-votes will not be considered as votes cast “FOR” or “AGAINST” this

We have audited the accompanying financial statements of RareGen, LLC, which comprise the balance sheets as of December 31, 2019 and 2018, and the related statements of operations, changes in members’ equity, and cash flows for the year ended December 31, 2019 and for the period from July 16, 2018 (inception) to December, 31, 2018, and the related notes to the financial statements.

Management’s Responsibility for the Financial Statements

Management is responsible for the preparation and fair presentation of these financial statements in accordance with accounting principles generally accepted in the United States of America; this includes the design, implementation, and maintenance of internal control relevant to the preparation and fair presentation of financial statements that are free from material misstatement, whether due to fraud or error.

Auditor’s Responsibility

Our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits in accordance with auditing standards generally accepted in the United States of America. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free from material misstatement.

An audit involves performing procedures to obtain audit evidence about the amounts and disclosures in the financial statements. The procedures selected depend on the auditor’s judgment, including the assessment of the risks of material misstatement of the financial statements, whether due to fraud or error. In making those risk assessments, the auditor considers internal control relevant to the entity’s preparation and fair presentation of the financial statements in order to design audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the entity’s internal control. Accordingly, we express no such opinion. An audit also includes evaluating the appropriateness of accounting policies used and the reasonableness of significant accounting estimates made by management, as well as evaluating the overall presentation of the financial statements.

We believe that the audit evidence we have obtained is sufficient and appropriate to provide a basis for our audit opinion.

Opinion

In our opinion, the financial statements referred to above present fairly, in all material respects, the financial position of RareGen, LLC as of December 31, 2019 and 2018, and the results of its operations and its cash flows for the year ended December 31, 2019 and for the period from July 16, 2018 (inception) to December 31, 2018 in accordance with accounting principles generally accepted in the United States of America.

Emphasis of Matter

As described in Note 9 to the financial statements, there is uncertainty related to the COVID-19 outbreak and impact on the Company’s business. Our opinion is not modified with respect to this matter.

Notes to Financial Statements

1. Background and Organization

Nature of Business

The Company was formed on July 16, 2018, as a Limited Liability Company (“LLC”) under State of Delaware statutes. Under the terms of the LLC Operating Agreement, the term of the Company continues in perpetuity.

RareGen, LLC (the “Company”) provides strategy, commercialization, and investment support to companies developing therapeutics addressing rare diseases. The Promotion Agreement, executed on August 1, 2018, with Sandoz, Inc. is the Company’s first partnership, in which the parties will launch the first-to-file generic of Treprostinil Injection for the treatment of patients with Pulmonary Arterial Hypertension (“PAH”).

2. Summary of Significant Accounting Policies

Basis of Presentation

The accompanying financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) as determined by the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”).

Use of Estimates

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

Cash and Cash Equivalents

Cash and cash equivalents include all cash balances, and highly liquid investments with an initial maturity of three months or less. Cash equivalents include money market accounts.

The Company maintains its cash in bank deposit accounts which, at times, may exceed federally insured limits. Accounts are guaranteed by the Federal Deposit Insurance Corporation (“FDIC”) up to certain limits. At December 31, 2019 and 2018, the Company had approximately $3,313,000 and $830,000, respectively, in excess of FDIC-insured limits. The Company has not experienced any losses in such accounts.

Accounts Receivable

Accounts receivable balances are monitored by management to determine if they are uncollectible. The Company has recorded no allowance for doubtful accounts at December 31, 2019 and 2018.

Credit risk and concentrations

At December 31, 2019 and 2018 and for the year ended December 31, 2019, one customer accounted for 100% of total accounts receivable and net service revenue.

Property and Equipment

Property and equipment are recorded at cost, less accumulated depreciation. The costs of major repairs and maintenance that extend the useful life of the asset are capitalized and normal maintenance and repairs are charged to expense as incurred. Depreciation is computed by the straight-line method over the

2. Summary of Significant Accounting Policies (continued)

estimated useful lives of the related assets, ranging from five to seven years. Upon retirement or sale of an asset, the cost and accumulated depreciation are removed from the accounts and any gain or loss is reflected in operations.

Impairment of Long-lived Assets

The Company reviews the carrying value of property, plant, and equipment for impairment whenever events and circumstances indicate that the carrying value of an asset may not be recoverable from the estimated future cash flows expected to result from its use and eventual disposition. In cases where undiscounted expected future cash flows are less than the carrying value, an impairment loss is recognized equal to an amount by which the carrying value exceeds the fair value of the assets. The factors considered by management in performing this assessment include current operating results, trends, and prospects, as well as the effects of obsolescence, demand, competition, and other economic factors. No impairment losses were recorded for long-lived assets during 2019 or 2018.

Intangible Assets

Intangible assets that have finite useful lives are amortized by the Company using the straight-line method over their estimated useful lives and are evaluated for impairment when indicators of such are present. Intangible assets are considered impaired if the fair value of the intangible assets is lower than carrying value. The fair value of intangible assets is determined based upon the present values of expected future cash flows using discount rates commensurate with the risks involved in the asset, or upon estimated replacement cost. The Company did not incur any impairment charges to intangible assets during the periods ended December 31, 2019 or 2018, respectively.

Operating Leases

Total rent payments under operating leases that include scheduled payment increases are amortized on a straight-line basis over the term of the lease.

Fair Value of Financial Instruments

Estimates of fair value for certain assets may be necessary from time to time if impairment concerns are present. For such measurements, the Company has adopted FASB guidance on fair value measurements. The provisions of the guidance provide a framework for measuring fair value under GAAP and defines fair value as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. This guidance requires that valuation techniques maximize the use of observable inputs and minimize the use of unobservable inputs.

This guidance also establishes a fair value hierarchy which prioritizes the valuation inputs into three broad levels. Based on the underlying inputs, each fair value measurement in its entirety is reported in one of three levels:

Level 1 —

Observable inputs such as quoted prices (unadjusted) in active markets for identical assets or liabilities.

Level 2 —

Inputs other than quoted prices that are observable for the asset or liability, either directly or indirectly. These include quoted prices for similar assets and liabilities in active markets and quoted prices identical or similar assets and liabilities in markets that are not active.

F-8

TABLE OF CONTENTS

RAREGEN, LLC

Notes to Financial Statements

2. Summary of Significant Accounting Policies (continued)

Level 3 —

Unobservable inputs that cannot be corroborated by observable market data and reflect the use of significant management judgment. These values are generally determined using pricing models for which the assumptions utilize management’s estimates of market participant assumptions.

The Company’s financial instruments include its cash equivalents, accounts receivable, accounts payable, and due to related party. The carrying values are believed to approximate fair values due to their short-term nature. The carrying values associated with related party financial instruments cannot be presumed to approximate fair value due to the absence of comparable transactions.

Revenue Recognition

The Company recognizes revenue in accordance with Accounting Standards Update (ASU) 2014-09, Revenue from Contracts with Customers (Topic 606). The core principle of Topic 606 is that a company should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services. The following five steps are applied to achieve that core principle:

•

Step 1: Identify the contract with the customer

•

Step 2: Identify the performance obligations in the contract

•

Step 3: Determine the transaction price

•

Step 4: Allocate the transaction price to the performance obligations in the contract

•

Step 5: Recognize revenue when the company satisfies a performance obligation

In order to identify the performance obligations in a contract with a customer, the company assesses the promised goods or services in the contract and identifies each promised good or service that is distinct.

If a good or service is not distinct, the good or service is combined with other promised goods or services until a bundle of goods or services is identified that is distinct.

The transaction price is the amount of consideration to which an entity expects to be entitled in exchange for transferring promised goods or services to a customer. The consideration promised in a contract with a customer may include fixed amounts, variable amounts, or both.

Variable consideration is included in the transaction price only to the extent that it is probable that a significant reversal in the amount of cumulative revenue recognized will not occur when the uncertainty associated with the variable consideration is subsequently resolved. The Company evaluates any non-cash consideration, consideration payable to the customer, and whether consideration contains a significant financing element in determining the transaction price.

Revenue is measured based on consideration specified in a contract with a customer. The Company recognizes revenue when it satisfies a performance obligation by transferring control over a service to a customer.

On August 1, 2018, the Company partnered with Sandoz, Inc. in a Promotion Agreement (the “Agreement”) to launch the first-to-file generic of Treprostinil Injection for the treatment of patients with PAH. Under the Agreement, the Company will provide certain promotional and nonpromotional activities on an exclusive basis for the product in the United States of America for the treatment of PAH, in exchange for a share of Sandoz, Inc.’s net profits, as defined within the Agreement. In addition, the Company paid Sandoz, Inc. $20 million at the inception of the agreement, in consideration for the right to conduct the promotional activities for the product. In exchange for its services, the Company is entitled to receive a

2. Summary of Significant Accounting Policies (continued)

The Company determined that certain activities within the contract are within the scope of ASC 808, Collaborative Arrangements. The commercialization of the product is a joint operating activity where the Company will provide promotional activities for Sandoz, Inc.’s intellectual property and Sandoz, Inc. will be responsible for items such as supply of the product, distribution to customers, managing sales, returns, and regulatory matters, and protection of patents. Both parties will be active participants, each carrying out its assigned responsibilities, and participating in the joint operating activity and will share in the risks and rewards of the commercialization through the profit-sharing arrangement.

In addition, the Company determined that the services provided under the agreement fall within the scope of Topic 606. While this is the Company’s first income-generating contract, the promotional activities the Company will perform are one of the services the Company expects to provide as part of its ordinary activities, and it is receiving consideration for this service from Sandoz, Inc. in the form of a share of future net profits. The Company has one combined performance obligation under the Agreement, which is to perform promotional and non-promotional activities to encourage the appropriate use of the product in accordance with the product labeling and applicable law. As such, and in accordance with ASU 2018-18: Clarifying the Interaction between Topic 808 and Topic 606, the Company will account for the entire Agreement under Topic 606.

The share of net profits due to the Company under the Agreement represents variable consideration as described in Topic 606 that is subject to a number of uncertainties, including the level of acceptance the product achieves from health care providers that must prescribe the product to their patients, or by payors such as insurers who must add the product to their list of covered drugs, “gross to net” revenue adjustments, Sandoz, Inc.’s costs, and competition from other products that have or may enter the market. As such, the recognition of revenue over time will be limited to the amount that is payable based on the net profit hurdles achieved to date. The Company will receive payments representing its share of net profits on a quarterly basis based on net profits received by Sandoz, Inc. to date during the term of the Agreement.

The $20 million paid by the Company to Sandoz, Inc. as consideration payable to the customer has been recorded as an asset that will be amortized on a straight-line basis into income as contra revenue over the initial term of five-year contract.

The Agreement has customary termination provisions for breach, bankruptcy of one of the parties, withdrawal of marketing approval, and safety concerns. Both parties have the right to terminate the Agreement before the end of the initial term in certain circumstances including if net profits targets are not reached or after aggregate net profits received by the other party has reached a specified hurdle.

The product was launched in March of 2019. For the year ended December 31, 2019, the Company recognized revenues for its share of net profits under the Agreement of approximately $10.1 million including contra revenue of approximately $3.3 million, related to the amortization of the upfront payments. At December 31, 2019 and 2018, the unamortized balances of the upfront payments made to Sandoz, Inc. were approximately $16.7 million and $20 million, respectively, which are included in Intangibles, net in the Company’s Balance sheet.

New Accounting Pronouncements

In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842), which requires companies with leases to recognize on their balance sheets the assets and liabilities generated by contracts longer than a year. The total value is calculated based on the present value of the future lease payments and the expense is recognized over the life of the lease on a straight-line basis. In June 2020, the FASB issued ASU 2020-05, Revenue from Contracts with Customers (Topic 606) and Leases (Topic 842): Effective Dates for Certain Entities, which defers the effective date of ASU 2016-02 for certain entities that have not yet issued their

financial statements (or made financial statements available for issuance) reflecting the adoption of ASU 2016-02. The main provision of ASU 2020-05 allows entities to elect to adopt the guidance for fiscal years beginning after December 15, 2021. Early application continues to be permitted, which means that an entity may choose to implement Topic 842 before the deferred effective date. The Company has not adopted Topic 842 and is currently evaluating the implications of this standard.

3. Cash and Cash equivalents

Cash and Cash equivalents consisted of the following:

December 31,	2019			2018
Cash		$	111,079		$	1,080,784

Notes to Financial Statements

5. Property, Plant and Equipment (continued)

The Company incurred depreciation expense of $5,069 and $422 for the periods ended December 31, 2019 and 2018, respectively.

6. Related Party Transactions

The Company entered into a management agreement with a PBM Capital Group, a related party of the Company to provide accounting, administrative, management and other services to the Company. Management fees in the amount of approximately $300,000 and $192,000 were expensed for the periods ended December 31, 2019 and 2018, respectively. The amounts are shown in the accompanying statements of operations.

7. Commitments and Contingencies

Litigation

On April 16, 2019, the plaintiffs, the Company and Sandoz, Inc., asserted that the defendants, United Therapeutics and Smiths Medical ASD Inc, violated the Sherman Act and impeded unlawfully in the competition for a new generic drug that treats PAH, pulmonary arterial hypertension. The plaintiffs recently brought to market a generic form of Treprostinil. The plaintiffs allege that United Therapeutics prohibited specialty pharmacies from dispensing the cartridges necessary for Treprostinil to be administered through subcutaneous injection for use with generic Treprostinil. The plaintiffs asked the court to stop the defendants from denying patients access to the cartridges and sought a preliminary injunction to attain access to them. As of December 31, 2019, the litigation is still in process.

Various legal claims may also arise from time to time in the normal course of business, which, in the opinion of management, will not have a material effect on the financial position or results of operations of the Company.

8. Members’ Equity

The Company accounts for the common units pursuant to the LLC Agreement (the “Agreement”). The Company has the authority to issue common units. At December 31, 2019 and 2018, the number of common units authorized, issued, and outstanding was 10,000. Each common unit holder or member shall be entitled to one vote per common unit on any matter voted upon by the members of the Company. Such vote may be taken at a meeting of the members or by written consent.

Under the terms of the LLC Operating Agreement, allocations of profits, losses, and distributions are in the following priorities:

Profits for any fiscal year or any other period, other than Profits from a Terminating Capital Transaction, as defined in the Agreement, shall be allocated to the Members on a pro rata basis in proportion to respective Unit Percentages, as defined in the Agreement.

Losses for any fiscal year or any other period, other than Losses from a Terminating Capital Transaction, shall be allocated to the Members to the extent of and in proportion to their respective positive Capital Account balances and, thereafter, to the Members on a pro rata basis in proportion to their respective Unit Percentages.

8. Members’ Equity (continued)

Accordingly, the Company’s taxable income or loss is allocated to its members in accordance with their respective percentage ownership. Therefore, no provision or liability for income taxes has been included in the accompanying financial statements.

9. Subsequent Events

In preparing these financial statements, the Company has evaluated events and transactions for potential recognition and/or disclosure through July 17, 2020, the date these financial statements were available to be issued.

COVID-19

On January 30, 2020, the World Health Organization (“WHO”) announced a global health emergency because of a new strain of coronavirus originating in Wuhan, China (the “COVID-19 outbreak”) and the risks to the international community as the virus spreads globally beyond its point of origin. In March 2020, the WHO classified the COVID-19 outbreak as a pandemic, based on the rapid increase in exposure globally.

The resulting impact of COVID-19 on the economic environment may be significant and arises from impacts on business activity, including but not limited to:

Reduced demand for goods and services due to economic uncertainty;

Disruption of global supply chains due to restrictions placed on the movement of people and goods;

Lack of investment in capital improvements and construction, reducing demand for many goods and services; and

Reduction in market prices for commodities and financial assets, including equity and debt instruments.

The full impact of the COVID-19 outbreak continues to evolve as of the date of this report. As such, it is uncertain as to the full magnitude that the pandemic will have on the Company’s financial condition, liquidity, and future results of operations. Management is actively monitoring the impact of the global situation on its financial condition, liquidity, operations, suppliers, industry, and workforce. Given the daily evolution of the COVID-19 outbreak and the global responses to curb its spread, the Company is not able to estimate the effects of the COVID-19 outbreak on its results of operations, financial condition, or liquidity for fiscal year 2020.

Known and direct impacts to the Company’s business activities include the following:

•

The Company’s primary service relates to a life-sustaining, critical pharmaceutical for patients. As such, the demand for the service is directly impacted by these patient’s needs. The success of the Company’s business is dependent on the distribution and supply chain managed by Novartis. Sandoz, Inc., is a division of Novartis.

F-14

TABLE OF CONTENTS

RAREGEN, LLC

Notes to Financial Statements

9. Subsequent Events (continued)

•

While the Company is not currently experiencing a negative impact to its business, the Company is closely monitoring the situation as it develops. The Company’s sales force is not physically active in the field so that may impact the near-term growth of its business.

CARES Act

On March 27, 2020, President Trump signed into law the “Coronavirus Aid, Relief, and Economic Security (CARES) Act.” The CARES Act, among other things, includes provisions relating to refundable payroll tax credits, deferment of employer side social security payments, net operating loss carryback periods, alternative minimum tax credit refunds, modifications to the net interest deduction limitations, increased limitations on qualified charitable contributions, and technical corrections to tax depreciation methods for qualified improvement property.

It also appropriated funds for the Small Business Administration Paycheck Protection Program loans that are forgivable in certain situations to promote continued employment, as well as Economic Injury Disaster Loans to provide liquidity to small businesses harmed by COVID-19.

The Company has examined the impact that the CARES Act may have on its business and currently the Company does not believe there is an impact from the CARES Act. The Company will continue to examine any impact the CARES Act has on its financial condition, results of operations, or liquidity.

Amendment to the Agreement with Sandoz, Inc.

On May 8, 2020, the Agreement with Sandoz, Inc. was amended and significant provisions of the amendment are as follows:

Sandoz, Inc. and the Company will share any litigation proceeds in the current lawsuit or any future lawsuit they bring against United Therapeutics Corporation and Smiths Medical ASD, Inc. The parties will also share equally in any losses incurred and approved expenses incurred. Note 7 includes a description of the circumstances regarding this litigation.

As described below, Liquidia Technologies, Inc. (“Liquidia Technologies”) and the Company have entered into an Agreement and Plan of Merger (the “Merger Transaction”). Upon the closing of the Merger Transaction, the Company will use good faith efforts to bring cartridges to market and make cartridges available for use with the Product, the initial term of the Agreement will be extended to eight years, and the formula for sharing net profits will be altered in exchange for Sandoz Inc.’s waiver of its right to terminate the Agreement for a change in control. Sandoz Inc.’s waiver of its right to terminate the Agreement for a change in control will be granted only if the Merger Transaction closes on or prior to September 30, 2020.

Litigation financing agreement

On June 4, 2020 the Company entered into a financing agreement with Henderson SPV, LLC to cover the prospective costs of the litigation with United Therapeutics Corporation and Smiths Medical ASD, Inc., from the date of this agreement, in consideration for a share of the litigation proceeds. The share is a fixed percentage based on the litigation proceeds with various litigation proceed ranges. In the case where the Company has no proceeds from the litigation, Henderson SPV, LLC will not be owed, by the Company, the litigation expenses that were previously financed. Henderson SPV, LLC has not financed any costs of litigation as of the date of these financial statements.

2. Summary of Significant Accounting Policies (continued)

The share of net profits due to the Company under the Agreement represents variable consideration as described in Topic 606 that is subject to a number of uncertainties, including the level of acceptance the product achieves from health care providers that must prescribe the product to their patients, or by payors such as insurers who must add the product to their list of covered drugs, “gross to net” revenue adjustments, Sandoz, Inc.’s costs, and competition from other generics that have or may enter the market. As such, the recognition of revenue will be over time and limited to the amount that is payable based on the net profit hurdles achieved to date. The Company will receive payments representing its share of net profits on a quarterly basis based on net profits received by Sandoz, Inc. to date during the term of the Agreement.

The product was launched in March of 2019. For the three month period ended March 31, 2020, the Company recognized revenues for its share of net profits under the Agreement of approximately $3.8 million including contra revenue of approximately $1 million, related to the amortization of the upfront payments. For the three month period ended March 31, 2019, the Company recognized revenues for its share of net profits under the Agreement of approximately $4.7 million including contra revenue or approximately $333,000. At March 31, 2020 and December 31, 2019, the unamortized balances of the upfront payments made to Sandoz, Inc. were approximately $15.6 million and $16.6 million, respectively, which are included in Intangibles, net in the Company’s Balance sheet.

6. Related Party Transactions

The Company entered into a management agreement with a PBM Capital Group, a related party of the Company to provide accounting, administrative, management and other services to the Company. Management fees in the amount of approximately $60,000 and $120,000 were expensed for the periods ended March 31, 2020 and 2019, respectively. The amounts are shown in the accompanying statements of operations.

7. Commitments and Contingencies

Litigation

On April 16, 2019, the plaintiffs, the Company and Sandoz, Inc., asserted that the defendants, United Therapeutics and Smiths Medical ASD Inc, violated the Sherman Act and impeded unlawfully in the competition for a new generic drug that treats PAH, pulmonary arterial hypertension. The plaintiffs recently brought to market a generic form of Treprostinil. The plaintiffs allege that United Therapeutics prohibited specialty pharmacies from dispensing the cartridges necessary for Treprostinil to be administered through subcutaneous injection for use with generic Treprostinil. The plaintiffs asked the court to stop the defendants from denying patients access to the cartridges and sought a preliminary injunction to attain access to them. As of March 31, 2020, the litigation is still in process.

8. Members’ Equity

The Company accounts for the common units pursuant to the LLC Agreement (the “Agreement”). The Company has the authority to issue common units. At March 31, 2020 and December 31, 2019, the number of common units authorized, issued, and outstanding was 10,000. Each common unit holder or member shall be entitled to one vote per common unit on any matter voted upon by the members of the Company. Such vote may be taken at a meeting of the members or by written consent.

Under the terms of the LLC Operating Agreement, allocations of profits, losses, and distributions are in the following priorities:

Cash Distributions: The Company may, in the sole and absolute discretion of the Board, distribute annually to the Members (or in the Board’s discretion, more frequently) an amount not to exceed Distributable Cash, as defined in the Agreement, for such fiscal year or other period, or the net proceeds to the Company from any financing or refinancing to the Members on a pro rata basis in proportion to their respective Unit Percentages. As an LLC, the Company is not a taxpaying entity for federal income tax purposes. Accordingly, the Company’s taxable income or loss is allocated to its members in accordance with their respective percentage ownership. Therefore, no provision or liability for income taxes has been included in the accompanying financial statements.

9. COVID-19

The resulting impact of COVID-19 on the economic environment may be significant and arises from impacts on business activity, including but not limited to:

Reduced demand for goods and services due to economic uncertainty;

Disruption of global supply chains due to restrictions placed on the movement of people and goods;

Lack of investment in capital improvements and construction, reducing demand for many goods and services; and

Reduction in market prices for commodities and financial assets, including equity and debt instruments.

The full impact of the COVID-19 outbreak continues to evolve as of the date of these financial statements. As such, it is uncertain as to the full magnitude that the pandemic will have on the Company’s financial condition, liquidity, and future results of operations. Management is actively monitoring the impact of the global situation on its financial condition, liquidity, operations, suppliers, industry, and workforce. Given the daily evolution of the COVID-19 outbreak and the global responses to curb its spread, the Company is not able to estimate the effects of the COVID-19 outbreak on its results of operations, financial condition, or liquidity for fiscal year 2020.

Known and direct impacts to the Company’s business activities include the following:

(b) No later than the earlier of (i) fifteen (15) days after the completion of the final reconciliation for the 2021 calendar year pursuant to Section 6.6.2 of the Sandoz Agreement and (ii) March 31, 2022, HoldCo shall prepare and deliver to the Members’ Representative a statement (the “Draft Net Sales Report”) that sets forth (A) HoldCo’s good faith calculations of the Net Sales for the Net Sales Earnout Period, (B) whether the Net Sales Target has been achieved and therefore, if the Net Sales Earnout Issuance would be owed, and all or any portion of the Net Sales Earnout Shares would be issued pursuant to Section 2.5.1, and (C) the number of Net Sales Earnout Shares to be issued. The Draft Net Sales Report shall be prepared using the Net Sales information as reported to HoldCo or RareGen Surviving LLC in accordance with the Sandoz Agreement, subject to any adjustments mutually agreed upon by Sandoz, HoldCo and Members’ Representative.

The Members’ Representative agrees to maintain confidentiality of any and all information in accordance with Section 5.5. Failure by the Members’ Representative to object to HoldCo’s calculation of Net Sales or, if earlier, the Members’ Representative’s affirmative agreement in writing to HoldCo’s calculations shall be deemed to be the Members’ Representative’s acceptance of the Draft Net Sales Report and that Draft Net Sales Report shall automatically and irrevocably be deemed a Final Net Sales Report in accordance with this Section 2.5 and shall have full weight and accord of a res judicata decision (final judgment without any possible way of recourse or appeal), except in the case of Fraud. Any objection to a Draft Net Sales Reportthat could have been, but was not, raised as an objection prior to such Draft Net Sales Reportbecoming a Final Net Sales Report is expressly waived. HoldCo shall make the Net Sales Earnout Issuance, if any, pursuant to Section 2.5.1.

(f) The Draft Net Sales Report, as adjusted based on the final resolution of each item set forth in the Members’ Representative’s Net Sales Response, in accordance with this Section 2.5.3, if any, is referred to as a “Final Net Sales Report.” Unless either HoldCo or Members’ Representative has engaged in Fraud in connection with the matters described in this Section 2.5.3, the Final Net Sales Report shall have the legal effect of an arbitral award and shall be final, binding, and conclusive on the parties hereto and shall automatically and irrevocably be deemed the Final Net Sales Report in accordance with this Section 2.5.3 and shall have full weight and accord of a res judicata decision (final judgment without any possible way of recourse or appeal), except in the case of Fraud. Unless either HoldCo or Members’ Representative has engaged in Fraud in connection with the matters described in this Section 2.5.3, any objection to a Draft Net Sales Report that could have been, but was not, raised as an objection in accordance with the terms of this Section 2.5.3 prior to such Draft Net Sales Report becoming a Final Net Sales Report is expressly waived.

HoldCo shall have been deemed to have fully satisfied its obligation to issue the Net Sales Earnout Shares, if any, by instructing the Exchange Agent to issue the Net Sales Earnout Shares.

Notwithstanding the foregoing or anything herein to the contrary, (i) HoldCo shall, and HoldCo shall cause RareGen Surviving LLC to, use commercially reasonable efforts to achieve the Net Sales Target, and (ii) not act in a manner that intentionally reduces the Net Sales for the Net Sales Earnout Period (including any action that would accelerate any Net Sales to a period prior to the Net Sales Earnout Period or defer any Net Sales to any period after the Net Sales Earnout Period, except to the extent that any such action is conducted in the ordinary course of business).

These rights shall survive consummation of the Mergers and are intended to benefit, and shall be enforceable by, each RareGen Member. The obligations of HoldCo under this Section 2.5 shall not be terminated or modified (whether by operation of law or otherwise) in such manner as to adversely affect the rights of any RareGen Member without the consent of such RareGen Member.

Section 2.6 Holdback Shares.

Section 5.3 Registration Statement; Proxy Statement. As promptly as practicable after the execution of this Agreement, Liquidia and RareGen shall prepare and HoldCo shall file with the SEC a proxy statement relating to the meeting of Liquidia’s stockholders to be held in connection with the Mergers (together with any amendments thereof or supplements thereto, the “Proxy Statement”) and HoldCo shall, with the assistance of Liquidia and RareGen, prepare and file with the SEC a registration statement on Form S-4 (together with all amendments thereto, the “Registration Statement”) in which the Proxy Statement shall be included as a prospectus, in connection with the registration under the Securities Act of the shares of HoldCo Common Stock to be issued to the stockholders of Liquidia and the RareGen Members pursuant to the Mergers. In connection with any Tax opinion required to be attached as an exhibit to the Registration Statement, each of HoldCo, Liquidia, RareGen, Liquidia Merger Sub and RareGen Merger Sub shall cooperate with each of Cooley and DLA (each such counsel, “Tax Counsel”) and shall deliver to each Tax Counsel customary representations and covenants. HoldCo and Liquidia shall use commercially reasonable efforts to prepare and file with the SEC any Other Filings as and when required or requested by the SEC. Each of HoldCo, Liquidia and RareGen shall use commercially reasonable efforts to respond to any comments made by the SEC with respect to the Registration Statement, the Proxy Statement and any Other Filings, and to cause the Registration Statement to become effective as promptly as practicable. Each of HoldCo, Liquidia and RareGen shall furnish all information concerning it (including, without limitation, financial statements prepared in accordance with Regulation S-X under the Securities Act as and to the extent required to be included in the Registration Statement in accordance with the rules and regulations of the SEC) and the holders of its capital stock as the other may reasonably request in connection with such actions and the preparation of the Registration Statement, the Proxy Statement and any Other Filings.

HoldCo shall advise Liquidia and RareGen, promptly after it receives notice thereof, of the time when the Registration Statement has become effective or any supplement or amendment has been filed, of the issuance of any stop order, the suspension of the qualification of the HoldCo Common Stock issuable in connection with the Mergers for offering or sale in any jurisdiction, or any request by the SEC for amendment of the Registration Statement, the Proxy Statement or any Other Filings or comments thereon and responses thereto or requests by the SEC for additional information.

as to form and substance in all material respects with the applicable requirements of the Securities Act, the Exchange Act and other applicable Law.

If at any time prior to the Effective Time, any event or circumstance relating to RareGen or its officers or directors, should be discovered by RareGen which should be set forth in an amendment or a supplement to the Registration Statement, the Proxy Statement or any Other Filing, RareGen shall promptly inform HoldCo and Liquidia and cooperate in filing or assist in filing with the SEC or its staff or any other Governmental Entity or officials thereof, or mailing or assisting in preparing and mailing to securityholders of Liquidia such amendment or supplement.

Section 5.4 Liquidia Stockholders’ Meeting. Liquidia shall duly call, give notice of, and cause to be held, a special meeting of its stockholders (the “Liquidia Stockholders’ Meeting”) as promptly as practicable after the date on which the Registration Statement is declared effective by the SEC (and in any event on or before the sixtieth (60th) day after the date that the Registration Statement is declared effective) for the purpose of voting upon the adoption and approval of this Agreement, the Liquidia Merger, and any other matters required by the transactions contemplated hereby. Liquidia shall use its best efforts to hold the Liquidia Stockholders’ Meeting as soon as practicable after the date on which the Registration Statement becomes effective and recommend that Liquidia’s stockholders vote in favor of the adoption and approval of this Agreement and the Liquidia Merger (the “Liquidia Board Recommendation”). Liquidia may only postpone or adjourn the Liquidia Stockholders’ Meeting to solicit additional proxies for the purpose of obtaining the Requisite Liquidia Vote, for the absence of a quorum and to allow reasonable additional time for the filing and/or mailing of any supplemental or amended disclosure that Liquidia has determined after consultation with outside legal counsel is reasonably likely to be required under applicable Law and for such supplemental or amended disclosure to be disseminated and reviewed by stockholders of Liquidia prior to the Liquidia Stockholders’ Meeting. The Liquidia Board and Liquidia shall use its reasonable best efforts to obtain from the stockholders of Liquidia the Requisite Liquidia Vote, including by communicating to its stockholders the Liquidia Board Recommendation (and including such recommendation in the Proxy Statement). Except as set forth in this Section 5.4, neither Liquidia, nor the Liquidia Board (nor any committee of the Liquidia Board) shall (A) withhold, withdraw or modify in any manner adverse to RareGen or propose publicly to withhold, withdraw or modify in any manner adverse to RareGen, the Liquidia Board Recommendation or approval, recommendation or declaration of advisability by Liquidia, the Liquidia Board or any such committee thereof with respect to this Agreement or the transactions contemplated hereby or thereby, (B) approve or recommend to its stockholders, or resolve to or publicly propose or announce its intention to approve or recommend to its stockholders, an Alternative Proposal or (C) fail to publicly, finally and without qualification (i) recommend against any Alternative Proposal or (ii) reaffirm the Liquidia Board Recommendation, in each case, within 10 Business Days after such Alternative Proposal is made public or any request by RareGen to do so (which request may be made once per Alternative Proposal (and any material change thereto)) (any of the foregoing, a “Change in Recommendation”). However, prior to the receipt of the Requisite Liquidia Vote, Liquidia and the Liquidia Board are permitted to make a Change in Recommendation if, but only if, and only to the extent that: (a) Liquidia and the Liquidia Representatives have complied in all material respects with Section 5.6; (b) an unsolicited bona fide written Alternative Proposal (that did not result from a breach of Section 5.6) is made to Liquidia by a third party, and such Alternative Proposal is not withdrawn; (c) the Liquidia Board, after consultation with its outside counsel, has determined in good faith, after giving effect to all of the adjustments which may be offered by RareGen pursuant to subclause (3) of item (d) below, that failure to make a Change in Recommendation would violate the Liquidia Board’s fiduciary duties under applicable Law; and (d) (1) the Liquidia Board has concluded in good faith, after giving effect to all of the adjustments which may be offered by RareGen pursuant to subclause (3) below, that such Alternative Proposal constitutes a Superior Proposal, (2) Liquidia has notified RareGen, at least five Business Days in advance, of its intention to make a Liquidia Change in Recommendation in response to such Superior Proposal (including the identity of the party making such Alternative Proposal) and furnished to RareGen a written description of the material terms of the Superior Proposal or an unredacted copy of such written Superior Proposal, and (3) before making such a Change in Recommendation, Liquidia has, and has caused its financial and legal advisors to, during the period after Liquidia’s delivery of the notice referred to in subclause (2) above, negotiated with RareGen in good faith for a period of up to five Business Days (to the extent RareGen desires to negotiate) to make such adjustments in the terms and conditions of this Agreement so that such Alternative Proposal ceases to constitute a Superior Proposal. Any change to the

A-31

TABLE OF CONTENTS

material terms of an Alternative Proposal shall require a new notice of Liquidia’s intention to make a Change in Recommendation and the provisions of this Section 5.4 shall apply anew to such Alternative Proposal. Notwithstanding anything to the contrary herein, unless this Agreement has been terminated in accordance with its terms, the Liquidia Stockholders’ Meeting shall be convened and this Agreement shall be submitted to the stockholders of Liquidia at the Liquidia Stockholders’ Meeting for the purpose of voting on the adoption of this Agreement and the other matters contemplated hereby.

Section 5.5 Access to Information; Confidentiality.

Section 5.5.1 Except as required pursuant to any confidentiality agreement or similar agreement or arrangement to which RareGen is a party (which such entity shall use its commercially reasonable efforts to cause the counterparty to waive), from the date of this Agreement to the Effective Time, RareGen shall, and shall cause each of its directors, officers, and employees (such persons, together with its accountants, consultants, legal counsel, advisors and agents and other representatives, the “RareGen Representatives”) to (A) provide to Liquidia and its officers, directors and employees (such persons, together with its accountants, consultants, legal counsel, advisors, agents and other representatives, the “Liquidia Representatives”) reasonable access at reasonable times upon prior notice to the officers, employees, agents, properties, offices and other facilities of RareGen and to the books and records thereof and (B) furnish promptly such information concerning the business, properties, contracts, assets, liabilities, personnel and other aspects of RareGen as Liquidia or the Liquidia Representatives may reasonably request; provided, that, in each case, such access may be limited to the extent that RareGen reasonably determines, in light of the Coronavirus (COVID-19) pandemic (taking into account any “shelter-in-place” or similar order issued by a Governmental Entity), that such access would jeopardize the health and safety of any person (whether an employee or otherwise). Except as required pursuant to any confidentiality agreement or similar agreement or arrangement to which Liquidia is a party (which Liquidia shall use its commercially reasonable efforts to cause the counterparty to waive), from the date of this Agreement to the Effective Time, Liquidia shall, and shall cause each of the Liquidia Representatives to (A) provide to RareGen and the RareGen Representatives reasonable access at reasonable times upon prior notice to the officers, employees, agents, properties, offices and other facilities of such party and its subsidiaries and to the books and records thereof and (B) furnish promptly such information concerning the business, properties, contracts, assets, liabilities, personnel and other aspects of such party and its subsidiaries as RareGen or the RareGen Representatives may reasonably request; provided, that, in each case, such access may be limited to the extent that Liquidia reasonably determines, in light of the Coronavirus (COVID-19) pandemic (taking into account any “shelter-in-place” or similar order issued by a Governmental Entity), that such access would jeopardize the health and safety of any person (whether an employee or otherwise). Notwithstanding the foregoing, neither Liquidia nor RareGen shall be required to disclose any information to the other party to the extent that Liquidia or RareGen, as applicable, reasonably determines such disclosure (i) would jeopardize the attorney-client privilege, (ii) would reasonably be expected to result in a loss of trade secret protection or (iii) would contravene any applicable Law (provided that the other party shall use its reasonable best efforts (a) to allow for such access or disclosure in a manner that does not result in a loss of attorney-client privilege or (b) to develop an alternative to providing such information so as to address such matters that is reasonably acceptable to the other party).

Section 5.5.2 With respect to the information disclosed pursuant to Section 5.5.1 hereof, the parties shall comply with, and shall cause their respective Representatives to comply with, all of their respective obligations under that certain Confidentiality Agreement dated as of December 11, 2019, by and between Liquidia and RareGen (the “Confidentiality Agreement”).

Section 5.6 No Solicitation of Transactions.

Section 5.6.1 Neither Liquidia nor RareGen shall, directly or indirectly, take (and neither Liquidia nor RareGen shall authorize or permit the Liquidia Representatives or RareGen Representatives, as applicable, or, to the extent within Liquidia’s or RareGen’s control, other affiliates to take) any action to (A) solicit, initiate or knowingly encourage or facilitate (including by way of furnishing non-public information) any Alternative Proposal or RareGen Acquisition Proposal, as applicable; (B) enter into any agreement with respect to any Alternative Proposal or RareGen Acquisition Proposal, as applicable, or enter into any agreement, arrangement or understanding requiring it to abandon,

terminate or fail to consummate the Mergers or any other transaction contemplated by this Agreement or any Ancillary Agreement or (C) participate in any way in discussions or negotiations with, or furnish any information to, any person in connection with, or take any other action to facilitate (to the extent that such party knew or should have known it was facilitating) any inquiries or the making of any proposal that constitutes, or could reasonably be expected to lead to, any Alternative Proposal or RareGen Acquisition Proposal, as applicable. Upon execution of this Agreement, Liquidia and RareGen shall cease immediately and cause to be terminated any and all existing discussions or negotiations with any parties conducted heretofore with respect to an Alternative Proposal or RareGen Acquisition Proposal, as applicable, and promptly request that all confidential information with respect thereto furnished on behalf of Liquidia or RareGen, as applicable, be returned or destroyed. Notwithstanding anything to the contrary contained in this Agreement, unless this Agreement has been terminated in accordance with its terms, neither Liquidia nor RareGen shall, and it shall cause each of their subsidiaries and the Liquidia Representatives and the RareGen Representatives, as applicable, not to, execute or enter into any letter of intent, agreement in principle, merger agreement, asset or stock purchase or share exchange agreement, option agreement or other contract related to any Acquisition Proposal or RareGen Acquisition Proposal, as applicable (other than, in each case, a confidentiality agreement entered into in accordance with Section 5.6.3).

Section 5.6.2 Each of Liquidia and RareGen shall, as promptly as practicable (and in no event later than 24 hours after receipt thereof), advise the other party of any inquiry received by it relating to any potential Alternative Proposal or RareGen Acquisition Proposal, as applicable, and of the material terms of any proposal or inquiry, including the identity of the person and its affiliates making the same, that it may receive in respect of any such potential Alternative Proposal or RareGen Acquisition Proposal, as applicable, or of any information requested from it or of any negotiations or discussions being sought to be initiated with it, shall furnish to the other party an unredacted copy of any such proposal or inquiry, if it is in writing, or a written summary of any such proposal or inquiry, if it is not in writing, and shall keep the party reasonably informed on a reasonably prompt basis with respect to any not-insignificant developments with respect to the foregoing.

Section 5.6.3 If at any time after the date hereof and before the receipt of the Requisite Liquidia Vote, Liquidia and the Liquidia Representatives receive a bona fide, unsolicited written Acquisition Proposal that did not result from a breach of Section 5.6.1, Liquidia and the Liquidia Representatives may engage in negotiations and discussions with, and furnish any information and other access (so long as all such information and access has previously been made available to RareGen or is made available to RareGen before or concurrently with the time such information or access is made available to such person) to, any person making such Alternative Proposal if, and only if, the Liquidia Board determines in good faith, after consultation with outside legal and financial advisors, that (i) such Alternative Proposal constitutes or is reasonably likely to become a Superior Proposal and (ii) the failure of the Liquidia Board to furnish such information or access or enter into such discussions or negotiations would violate its fiduciary duties under applicable Law; but before furnishing any such information, Liquidia shall have received from the person making such Alternative Proposal an executed confidentiality agreement with terms at least as restrictive in all material respects on such person as the Confidentiality Agreement, which confidentiality agreement shall not prohibit Liquidia from complying with the terms of this Section 5.6.

Section 5.6.4 Neither the RareGen Board nor any committee thereof shall (A) withdraw or modify, or propose publicly to withdraw or modify, in a manner adverse to Liquidia, the approval or recommendation by the RareGen Board or such committee of the adoption and approval of the RareGen Merger; (B) other than the RareGen Merger, approve or recommend, or propose publicly to approve or recommend, any RareGen Acquisition Proposal or (C) other than the RareGen Merger, cause RareGen to enter into any letter of intent, agreement in principle, acquisition agreement or other similar agreement related to any RareGen Acquisition Proposal.

consummate and make effective the transactions contemplated by this Agreement and each Ancillary Agreement as promptly as practicable; (B) obtain from any Governmental Entity any consents, licenses, permits, waivers, approvals, authorizations or orders required to be obtained or made by HoldCo, Liquidia or RareGen or any of their respective Subsidiaries or Affiliates, or to avoid any action or proceeding by any Governmental Entity (including, without limitation, those in connection with the HSR Act, if required), in connection with the authorization, execution and delivery of this Agreement and each Ancillary Agreement and the consummation of the transactions contemplated herein and therein, including, without limitation, the Mergers and (C) make all necessary filings, and thereafter respond promptly to any reasonable requests by a Governmental Entity for additional information or documents relating thereto, with respect to this Agreement and each Ancillary Agreement and the Mergers required under (x) the Securities Act and the Exchange Act, and any other applicable federal or state securities Laws; (y) the HSR Act, if required, and (z) any other applicable Law. As soon as reasonably practicable, and in any event no less than forty (40) days before the Outside Date, Liquidia and RareGen will reasonably determine in good faith whether any filing is required to be made under the HSR Act for the consummation of the transactions contemplated by this Agreement. If the parties reasonably determine in good faith that any such filing is required in accordance with the immediately preceding sentence (the “HSR Filing Determination”), then each party shall use commercially reasonable efforts to prepare and file its respective filing under the HSR Act as promptly as is practicable, and in any event within five (5) Business Days of the HSR Filing Determination.

Section 5.7.2 HoldCo, Liquidia and RareGen shall cooperate with each other in connection with the making of all such filings, including by providing copies of all such documents to the non-filing party and its advisors prior to filing; provided, that, if necessary to protect information that is competitively sensitive or covered by any evidentiary privilege, such disclosures may be redacted or made to each party’s outside counsel only.

Nothing in this Agreement, including this Section 5.7.1 shall require HoldCo, Liquidia, or any of their respective Subsidiaries or Affiliates, to agree to, implement, or engage in (AA) any divestiture, hold-separate agreement, sale, license, or other disposition of any assets or businesses; (BB) any modification, limitation, or other restraint on the manner in which it conducts or operates any assets or businesses; or (CC) any litigation, arbitration, or other dispute or legal proceeding. RareGen and Liquidia shall use their commercially reasonably efforts to furnish to each other all information required for any application or other filing under the rules and regulations of any applicable Law (including all information required to be included in the Registration Statement and the Proxy Statement) in connection with the transactions contemplated by this Agreement and each Ancillary Agreement. RareGen and Liquidia shall not take any action or enter into any transaction, the effect of which would reasonably be expected to materially delay or prevent the consummation of the transactions contemplated in this Agreement. RareGen and Liquidia agree that nothing in this Agreement or any Ancillary Agreement shall prohibit Liquidia or HoldCo from taking any action in connection with the Equity Financing, and any such actions are expressly permitted hereby.

Section 5.7.3 RareGen and Liquidia shall give any notices to third parties, and use commercially reasonable efforts to obtain any third-party consents, (A) necessary, proper or advisable to consummate the transactions contemplated in this Agreement and each Ancillary Agreement; (B) required to be disclosed in the RareGen Disclosure Schedule or the Liquidia Disclosure Schedule, as applicable; (C) required to prevent a RareGen Material Adverse Effect or a Liquidia Material Adverse Effect from occurring prior to or after the Effective Time or (D) otherwise referenced in Section 6.1.5; provided, however, each of the parties acknowledges and agrees that obtaining any such third-party consents shall

A-34

TABLE OF CONTENTS

not be a condition to any of the transactions contemplated by this Agreement, including the Merger, except as expressly set forth in Article VI. In the event that either party shall fail to obtain any third-party consent described in the first sentence of this Section 5.7.2, such party shall use commercially reasonable efforts, and shall take any such actions reasonably requested by the other party hereto, to minimize any material adverse effect upon RareGen and Liquidia, and their respective businesses resulting, or which would reasonably be expected to result after the Effective Time, from the failure to obtain such consent.

Section 5.7.4 From the date of this Agreement until the Effective Time, each of RareGen and Liquidia shall promptly notify the other party in writing of, to the knowledge of such party, any pending or threatened action, suit, arbitration or other proceeding or investigation by any Governmental Entity or any other person (A) challenging or seeking material damages in connection with the Mergers or the conversion of Liquidia Common Stock or RareGen Common Units into HoldCo Common Stock pursuant to the Mergers or (B) seeking to restrain or prohibit the consummation of the Mergers or otherwise materially limit the right of HoldCo or any HoldCo Subsidiary to own or operate all or any portion of the businesses or assets of Liquidia, or RareGen, which in either case would reasonably be expected to have a RareGen Material Adverse Effect or a Liquidia Material Adverse Effect prior to or after the Effective Time.

Section 5.8 Certain Notices. From and after the date of this Agreement until the Effective Time, each party hereto shall promptly notify the other parties hereto of (A) the occurrence, or non-occurrence, of any event that would be reasonably likely to cause any condition to the obligations of any party to effect the Mergers and the other transactions contemplated by this Agreement not to be satisfied or (B) the failure of RareGen or Liquidia, as the case may be, to comply with or satisfy any covenant, condition or agreement to be complied with or satisfied by it pursuant to this Agreement which would reasonably be expected to result in any condition to the obligations of any party to effect the Mergers and the other transactions contemplated by this Agreement not to be satisfied; provided, however, that any failure to give notice in accordance with the foregoing with respect to any breach shall not be deemed to constitute a violation of this Section 5.8 or the failure of any conditions set forth in Section 6.2 or 6.3 to be satisfied, or otherwise constitute a breach of this Agreement by the party failing to give such notice; provided, further, that the delivery of any notice pursuant to this Section 5.8 shall not cure any breach of any representation or warranty requiring disclosure of such matter prior to the date of this Agreement or otherwise limit or affect the remedies available hereunder to the party receiving such notice.

With respect to any employee benefit plans of HoldCo in which any director, officer or employee of Liquidia (the “Liquidia Employees”) or any director, officer or employee of RareGen (the “RareGen Employees”) will participate effective as of the Effective Time, HoldCo shall, or shall cause the Surviving Entities to, recognize all service of Liquidia Employees with Liquidia or RareGen Employees with RareGen, as the case may be, for purposes of vacation and participation in, but not for purposes of benefit accrual, in any employee benefit plans of HoldCo in which such Liquidia Employees or RareGen Employees may be eligible to participate after the Effective Time.

Section 5.12 Indemnification of Directors and Officers.

Section 5.12.1 For not less than six (6) years from and after the Effective Time, HoldCo agrees to, and to cause the Surviving Entities to, indemnify and hold harmless all past and present directors, officers and employees of Liquidia and RareGen to the same extent such persons are indemnified as of the date of this Agreement by Liquidia and RareGen, as applicable, pursuant to the Liquidia Certificate and the Liquidia Bylaws and the RareGen Certificate and the RareGen Operating Agreement, as applicable, and indemnification agreements, if any, in existence on the date of this Agreement set forth on Section 5.12.1 of the Liquidia Disclosure Schedule and the RareGen Disclosure Schedule, as applicable, with any directors, officers and employees of Liquidia and RareGen, as applicable, for acts or omissions occurring at or prior to the Effective Time; provided, however, that HoldCo agrees to, and to cause the Surviving Entities to, indemnify and hold harmless such persons to the fullest extent permitted by Law for acts or omissions occurring in connection with the approval of this Agreement and the consummation of the transactions contemplated hereby.

Section 5.12.2 RareGen shall (i) obtain as of the Effective Time “tail” insurance policies with a claims period of six (6) years from and after the Effective Time, that provides coverage for events occurring prior to the Effective Time, that is substantially equivalent to RareGen’s existing policies (the “D&O Insurance”) (true and complete copies which have been previously provided to Liquidia). HoldCo shall, and shall cause the Surviving Entities to, maintain such policy in full force and effect, and continue to honor the obligations thereunder. The obligations under this Section 5.12 shall not be terminated or modified in such a manner as to adversely affect any indemnitee (or such indemnitee’s heirs, successors or assigns) to whom this Section 5.12 applies without the consent of such affected indemnitee (or such indemnitee’s heir, successor or assign), it being expressly agreed that the indemnitees (and such indemnitees’ heirs, successors and assigns) to whom this Section 5.12 applies shall be third-party beneficiaries of this Section 5.12.

Section 5.12.3 In the event HoldCo or the Surviving Entities (A) consolidate with or merge into any other person and shall not be the continuing or surviving corporation or entity of such consolidation or merger or (B) transfer all or substantially all of its properties and assets to any person, then, and in each such case, proper provisions shall be made so that such continuing or surviving corporation or entity or transferee of such assets, as the case may be, shall assume the obligations set forth in this Section 5.12.

Section 5.13.1 Each of HoldCo, Liquidia and RareGen shall use their respective reasonable best efforts to take all actions necessary for (i) the Liquidia Merger to qualify as a “reorganization” within the meaning of Section 368(a) of the Code and (ii) the Mergers, taken together, to qualify as an exchange described in Section 351 of the Code and the regulations promulgated thereunder. None of HoldCo, Liquidia or RareGen shall take or cause to be taken any action that would reasonably be expected to prevent or impede (i) the Liquidia Merger from qualifying as a “reorganization” within the meaning of Section 368(a) of the Code or (ii) the Mergers, taken together, from qualifying as an exchange described in Section 351 of the Code and the regulations promulgated thereunder.

Section 5.13.2 This Agreement is intended to constitute, and the parties hereby adopt this Agreement as, a plan of “reorganization” within the meaning of Treasury Regulation Sections 1.368-2(g) and 1.368-3(a). Each of HoldCo, Liquidia and RareGen shall, and shall cause their respective

Section 5.16.1 The amount of any Taxes for a Straddle Period allocable to the portion of the Straddle Period ending on the Closing Date shall (i) in the case of real and personal property Taxes and franchise Taxes not based on gross or net income, be equal to the amount of such Taxes for the entire Straddle Period multiplied by a fraction, the numerator of which is the number of calendar days in the portion of the Straddle Period ending on the Closing Date and the denominator of which is the number of calendar days in the entire Straddle Period and, (ii) in the case of other Taxes, be determined as if RareGen filed a separate Tax Return with respect to such Taxes for the portion of the Straddle Period ending at the end of the day on the Closing Date using a “closing of the books methodology” based on the actual operations of RareGen, but assuming a similar interim closing of the books of any pass-through entity in which RareGen owns an interest and that the tax year of such pass-through entity ended on the Closing Date, and provided that, in determining the amount of such Taxes, any exemptions, allowances or deductions that are calculated on a periodic basis (such as depreciation or amortization deductions) shall be pro-rated in the same manner as described in clause (i).

Section 5.16.2 The Members’ Representative shall, at the expense of the RareGen Members, timely prepare and file or cause to be prepared and filed all partnership income Tax Returns of RareGen for all taxable periods ending on or before the Closing Date that are due after the Closing Date. Any income Tax deductions of RareGen arising in connection with the transactions contemplated by this Agreement will be reflected in a partnership income Tax Return of RareGen for the Pre-Closing Period to the extent permitted by applicable Law. Prior to the filing of any such Tax Return, the Members’ Representative shall provide HoldCo with a final draft of such Tax Return at least fifteen (15) Business Days prior to the due date for such Tax Return (after taking into account any applicable extensions), and shall consider in good faith any reasonable comments made by HoldCo. Such Tax Returns shall be prepared or completed in a manner consistent with prior practice of RareGen, except as otherwise required by Law or otherwise agreed to in writing by HoldCo prior to the filing thereof.

Section 5.16.3 For each Pre-Closing Period, (i) RareGen shall, to the maximum extent permitted under applicable Law, make the Audit Opt-Out Election on its applicable Tax Returns and (ii) to the extent an Audit Opt-Out Election is not permitted to be made pursuant to applicable Law, RareGen shall timely elect pursuant to Section 6226 of the Code to have any partnership adjustments passed through to the RareGen Members or their predecessors-in-interest during the taxable period subject to such adjustment.

Section 5.16.4 Notwithstanding anything to the contrary herein, after the Closing Date, the Members’ Representative shall have the exclusive right to represent the interests of RareGen and the RareGen Members (at the RareGen Members’ expense) in any Tax Contests that relate solely to partnership income Taxes or partnership income Tax Returns of RareGen for any Pre-Closing Period.

Section 5.17 Takeover Statutes. None of RareGen, Liquidia, HoldCo or their respective boards of directors shall take any action that would cause Section 203 of the DGCL or any other similar takeover Law, including any “moratorium,” “control share,” “fair price,” “takeover” or “interested stockholder” Law, to become applicable to this Agreement, either of the Mergers, or any of the other transactions

A-37

If any takeover Laws may become, or may purport to be, applicable to the transactions contemplated hereby, each party and the members of their respective boards of directors will grant such approvals and take such actions as are necessary so that the transactions contemplated by this Agreement may be consummated as promptly as practicable on the terms contemplated hereby and thereby and otherwise act to eliminate or minimize the effects of any takeover Law on any of the transactions contemplated by this Agreement.

Section 5.19 Sandoz Payments. From and after the Effective Date, if the RareGen Surviving LLC receives or collects any Sandoz Payments allocable to any period prior to Closing, HoldCo shall cause the RareGen Surviving LLC to remit such funds to the Members’ Representative no later than April 15, 2021. For purposes of calculating the portion of any Sandoz Payment that is allocable to a period prior to Closing, the Sandoz Payments received by RareGen and attributable to any given calendar month shall be allocated to the period prior to Closing as follows: (A) with respect to Sandoz Payments that are attributable to any calendar month that expires prior to the Closing, 100% shall be allocated to the period prior to Closing, and (B) with respect to Sandoz Payments that are attributable to any calendar month that commenced prior to the Closing but expires after the Closing, a fraction of such Sandoz Payments shall be allocated to the period prior to Closing, the numerator of which is the number of calendar days in the portion of the calendar month ending on the Closing Date and the denominator of which is the number of calendar days in the entire calendar month.

Section 5.20 Disclosure Documents.

(a) any inaccuracy in or breach of any of the representations or warranties of RareGen contained in this Agreement or in any certificate or instrument delivered by or on behalf of RareGen pursuant to this Agreement, as of the date such representation or warranty was made or as if such representation or warranty was made on and as of the Closing Date (except for representations and warranties that expressly relate to a specified date, the inaccuracy in or breach of which will be determined with reference to such specified date);

“Claim Threshold”) and any such Losses below the Claim Threshold shall not be taken into account or aggregated for purposes of determining the applicability of the limitations set forth in Section 7.2.2(b); provided, however, that the Claim Threshold shall not apply with respect to Losses arising out of or resulting from any inaccuracy in or breach of any Fundamental Representation or Tax Representation.

(b) RareGen Members shall not be liable to the Liquidia Indemnitees for indemnification under Section 7.2.1(a) until the aggregate amount of all Losses in respect of indemnification under Section 7.2.1(a) exceeds $200,000 (the “Basket”), in which event the RareGen Members shall be required to pay or be liable for all such Losses in excess of the Basket; provided, however, that the Basket shall not apply with respect to Losses arising out of or resulting from any inaccuracy in or breach of any Fundamental Representation or Tax Representation. Other than Losses arising out of or resulting from any inaccuracy in or breach of any Fundamental Representation or Tax Representation, or arising from Fraud, the aggregate amount of all Losses for which the RareGen Members shall be liable pursuant to Section 7.2.1(a) shall not exceed $3,700,000 (the “Cap”). The aggregate amount of all Losses arising out of or resulting from any inaccuracy in or breach of any Fundamental Representation or Tax Representation for which the RareGen Members shall be liable, when added to any other Losses for which RareGen Members may be liable hereunder, shall not exceed the Merger Consideration actually paid to the RareGen Members.

(d) Notwithstanding anything contained herein to the contrary, the Liquidia Indemnitees shall not be entitled to recover any Losses (i) relating to any matter arising under one provision of this Agreement to the extent that the Liquidia Indemnitees have already recovered the same Losses with respect to such matter pursuant to this Article 7, (ii) for any Non-Indemnified Taxes, (iii) to the extent the matter giving rise to such Loss had been reserved or provided for in the RareGen Financial Statements, (iv) that are contingent unless and until such contingent Losses becomes actual Losses (so long as the claim for such Losses was timely submitted pursuant to the provisions of this Article 7), (v) to the extent the Liquidia Indemnitees failed to mitigate such Losses or (vi) for any otherwise indemnifiable Losses arising out of any breach of any representation, warranty, covenant or agreement unless a claim therefore is asserted with specificity and in writing by such Liquidia Indemnitee timely in accordance with Sections 7.1 and 7.4 (failing which such claim shall be waived and extinguished).

(e) The amount of any Loss for which indemnification is provided under this Article 7 shall be net of any amounts recovered or recoverable by Liquidia Indemnitees from any third party (including under insurance policies, if any) with respect to such Loss. If a Liquidia Indemnitee recovers an amount from a third party in respect of Losses that are the subject of indemnification hereunder after all or a portion of such Losses have been paid by an Indemnifying Party pursuant to this Article 7, then the Liquidia Indemnitees shall promptly remit to the Indemnifying Party the excess (if any) of (i) (A) the amount paid by the Indemnifying Party in respect of such Losses plus (B) the amount received by the Liquidia Indemnitee from a third party in respect thereof over (ii) the full amount of the Losses. In the event that a Liquidia Indemnitee has any rights against a third party with respect to any Loss that results in a payment by an Indemnifying Party under this Article 7, such Indemnifying Party shall be subrogated to such rights to the extent of such payment. Without limiting the generality of any other provision hereof, each Liquidia Indemnitee shall duly execute upon request all instruments reasonably necessary to evidence and perfect the subrogation and subordination rights detailed herein, and otherwise cooperate in the prosecution of such claims.

Section 7.4 Indemnification Procedures. The party making a claim under this Article 7 is referred to as the “Indemnified Party”, and the party against whom such claims are asserted under this Article 7 is referred to as the “Indemnifying Party”.

Section 7.4.1 Third Party Claims. If any Indemnified Party receives notice of the assertion or commencement of any action made or brought by any person who is not a party to this Agreement or an Affiliate of a party to this Agreement or a Representative of the foregoing (a “Third Party Claim”) against such Indemnified Party with respect to which the Indemnifying Party is obligated to provide indemnification under this Agreement, the Indemnified Party shall give the Indemnifying Party prompt written notice thereof, but in any event not later than thirty (30) calendar days after receipt of such notice of such Third Party Claim. The failure to give such prompt written notice shall not, however, relieve the Indemnifying Party of its indemnification obligations, except and only to the extent that the Indemnifying Party is adversely affected (including if the Indemnifying Party forfeits rights or defenses) by reason of such failure. Such notice by the Indemnified Party shall describe the Third Party Claim in reasonable detail, shall include copies of all written evidence thereof and shall indicate the estimated amount, if reasonably determinable, of the Loss that has been or may be sustained by the Indemnified Party. The Indemnifying Party shall have the right to participate in, or by giving written notice to the Indemnified Party, to assume the defense of any Third Party Claim at the Indemnifying Party’s expense and by the Indemnifying Party’s own counsel, and the Indemnified Party shall cooperate in good faith in such defense; provided, that the Indemnifying Party shall not have the right

A-43

TABLE OF CONTENTS

to defend or direct the defense of any such Third Party Claim that seeks an injunction or other equitable relief against the Indemnified Parties. In the event that the Indemnifying Party assumes the defense of any Third Party Claim, subject to Section 7.4.2, it shall have the right to take such action as it deems necessary to avoid, dispute, defend, appeal or make counterclaims pertaining to any such Third Party Claim in the name and on behalf of the Indemnified Party. The Indemnified Party shall have the right to participate in the defense of any Third Party Claim with counsel selected by it subject to the Indemnifying Party’s right to control the defense thereof, with the fees and disbursements of such counsel being the expense of the Indemnified Party; provided, that if in the reasonable opinion of counsel to the Indemnified Party, (A) there are legal defenses available to an Indemnified Party that are different from or additional to those available to the Indemnifying Party; or (B) there exists a conflict of interest between the Indemnifying Party and the Indemnified Party that cannot be waived, the Indemnifying Party shall be liable for the reasonable and documented fees and expenses of one counsel to the Indemnified Party. If the Indemnifying Party elects not to compromise or defend such Third Party Claim, fails to promptly notify the Indemnified Party in writing of its election to defend as provided in this Agreement, or fails to diligently prosecute the defense of such Third Party Claim, the Indemnified Party may, subject to Section 7.4.2, pay, compromise, defend such Third Party Claim and seek indemnification for any and all Losses based upon, arising from or relating to such Third Party Claim. The Members’ Representative and HoldCo shall cooperate with each other in all reasonable respects in connection with the defense of any Third Party Claim, including making available records relating to such Third Party Claim and furnishing, without expense (other than reimbursement of actual out-of-pocket expenses) to the defending party, management employees of the non-defending party as may be reasonably necessary for the preparation of the defense of such Third Party Claim.

Section 7.4.2 Settlement of Third Party Claims. Notwithstanding any other provision of this Agreement, the Indemnifying Party shall not enter into settlement of any Third Party Claim without the prior written consent of the Indemnified Party (which consent shall not be unreasonably withheld, conditioned or delayed), except as provided in this Section 7.4.2. If a firm offer is made to settle a Third Party Claim without leading to liability or the creation of a financial or other obligation on the part of the Indemnified Party and provides, in customary form, for the unconditional release of each Indemnified Party from all liabilities and obligations in connection with such Third Party Claim and the Indemnifying Party desires to accept and agree to such offer, the Indemnifying Party shall give written notice to that effect to the Indemnified Party. If the Indemnified Party fails to consent to such firm offer within ten (10) days after its receipt of such notice, the Indemnified Party may continue to contest or defend such Third Party Claim and in such event, the maximum liability of the Indemnifying Party as to such Third Party Claim shall not exceed the amount of such settlement offer. If the Indemnified Party fails to consent to such firm offer and also fails to assume defense of such Third Party Claim, the Indemnifying Party may settle the Third Party Claim upon the terms set forth in such firm offer to settle such Third Party Claim. If the Indemnified Party has assumed the defense pursuant to Section 7.4.1 or this Section 7.4.2, it shall not agree to any settlement without the written consent of the Indemnifying Party (which consent shall not be unreasonably withheld or delayed); provided, that any such consent shall not be determinative as to whether any Indemnified Party is entitled to indemnification under Article 7 or the amount of Losses relating to such matter.

Section 7.4.3 Any action by an Indemnified Party on account of a Loss which does not result from a Third Party Claim (a “Direct Claim”) shall be asserted by the Indemnified Party giving the Indemnifying Party prompt written notice thereof, but in any event not later than thirty (30) days after the Indemnified Party becomes aware of such Direct Claim. The failure to give such prompt written notice shall not, however, relieve the Indemnifying Party of its indemnification obligations, except and only to the extent that the Indemnifying Party is adversely affected (including if the Indemnifying Party forfeits rights or defenses) by reason of such failure. Such notice by the Indemnified Party shall describe the Direct Claim in reasonable detail, shall include copies of all material written evidence thereof and shall indicate the estimated amount, if reasonably determinable, of the Loss that has been or may be sustained by the Indemnified Party. The Indemnifying Party shall have thirty (30) days after its receipt of such notice to respond in writing to such Direct Claim. The Indemnified Party shall allow the Indemnifying Party and its professional advisors to investigate the matter or circumstance alleged to give rise to the Direct Claim, and whether and to what extent any amount is payable in respect of the Direct Claim and the Indemnified Party shall assist the Indemnifying Party’s investigation by giving

The Liquidia Indemnitees shall seek recovery for any Losses pursuant to Sections 7.2.1(a) with respect to any Losses arising out of any inaccuracy in or breach of any Fundamental Representation or Tax Representation, (a) first, as a reduction of the number of Holdback Shares (to the extent there remains any Holdback Shares available for such reduction), (b) second, at the election of the Indemnifying Party, from (i) the return of shares of HoldCo Common Stock issued to the Indemnifying Party pursuant to this Agreement, or (ii) as an offset to any Net Sales Earnout Shares issuable to the Indemnifying Party pursuant to Section 2.5.1, and (c) third, directly from the RareGen Members by wire transfer of immediately available funds. The number of shares of HoldCo Common Stock that may be returned pursuant to this Section 7.5 shall be determined by dividing the aggregate amount of Losses to be satisfied by such return of HoldCo Common Stock by the Issuance Price per Share.

In furtherance of the foregoing, the Liquidia Indemnitees and RareGen Member Indemnitees waive, to the fullest extent permitted under Law, any and all rights, claims and causes of action for any breach of any representation, warranty, covenant, agreement or obligation set forth herein or otherwise relating to the subject matter of this Agreement it may have arising under or based upon any Law, except pursuant to the indemnification provisions set forth in this Article 7. Nothing in this Section 7.8 shall limit (a) any Liquidia Indemnitee’s right to seek and obtain any equitable relief to which such Liquidia Indemnitee shall be entitled or to seek any remedy against a RareGen Member on account of Fraud committed by such RareGen Member or (b) any RareGen Member Indemnitee’s right to seek and obtain any equitable relief to which such RareGen Member Indemnitee shall be entitled or to seek any remedy against HoldCo or Liquidia on account of Fraud committed by HoldCo or Liquidia.

Section 8.2.3.2 Notwithstanding anything to the contrary herein, but without limiting the right of any party to recover liabilities or damages to the extent permitted herein, Liquidia shall not be required to pay the Termination Fee more than once. Each of RareGen and Liquidia acknowledges that the agreements contained in this Section 8.2 are an integral part of the transactions contemplated by this Agreement, and that, without these agreements, the other party would not enter into this Agreement; accordingly, if Liquidia fails promptly to pay the amount due pursuant to this Section 8.2, and, in order to obtain such payment, RareGen commences a suit which results in a judgment against Liquidia for the Termination Fee or any portion thereof, Liquidia shall pay the costs and expenses of RareGen (including attorneys’ fees and expenses) in connection with such suit. In addition, if Liquidia fails to pay the amounts payable pursuant to this Section 8.2, then Liquidia shall pay interest on such overdue amounts at a rate per annum equal to the “prime rate” (as announced by JPMorgan Chase & Co. or any successor thereto) in effect on the date on which such payment was required to be made for the period commencing as of the date that such overdue amount was originally required to be paid.

Section 8.3 Amendment. This Agreement may be amended by the parties hereto by action taken by or on behalf of their respective boards of directors at any time prior to the Effective Time; provided, however, that, after approval of the Mergers by the stockholders of Liquidia, as applicable, no amendment may be made without further stockholder approval which, by Law or in accordance with the rules of any relevant stock exchange, requires further approval by such stockholders.

Section 8.4 Waiver. At any time prior to the Effective Time, any party hereto may: (A) extend the time for the performance of any of the obligations or other acts of the other party hereto; (B) waive any inaccuracies in the representations and warranties of the other party contained herein or in any document delivered pursuant hereto; and (C) waive compliance by the other party with any of the agreements or conditions contained herein; provided, however, that after any approval of the Mergers contemplated by this Agreement by the stockholders of Liquidia, there may not be, without further approval of such stockholders, any extension or waiver of this Agreement or any portion thereof which, by Law or in accordance with the rules of any relevant stock exchange, requires further approval by such stockholders. Any such extension or waiver shall be valid only if set forth in an instrument in writing signed by the party or parties to be bound thereby, but such extension or waiver or failure to insist on strict compliance with an obligation, covenant, agreement or condition shall not operate as a waiver of, or estoppel with respect to, any subsequent or other failure.

Section 8.5 Fees and Expenses. Except as otherwise provided for in this Agreement, all expenses incurred by the parties hereto shall be borne solely and entirely by the party which has incurred the same, except that all Transaction Expenses shall be paid by RareGen.

OPINION OF JEFFERIES LLC

June 29, 2020

The Board of Directors
Liquidia Technologies, Inc.
P.O. Box 110085
Research Triangle Park, NC 27709

Members of the Board:

We understand that Liquidia Technologies, Inc., a Delaware corporation (“Liquidia”), proposes to enter into an Agreement and Plan of Merger (the “Merger Agreement”) with RareGen LLC, a Delaware limited liability company (“RareGen”), Liquidia Corporation, a newly formed Delaware corporation and a wholly owned subsidiary of Liquidia (“HoldCo”), Gemini Merger Sub I, Inc., a Delaware corporation and a wholly owned subsidiary of HoldCo (“Liquidia Merger Sub”), Gemini Merger Sub II, Inc., a Delaware corporation and a wholly owned subsidiary of HoldCo (“RareGen Merger Sub”) and PBM RG Holdings, LLC, a Delaware limited liability company. Capitalized terms used herein, but not defined herein, shall have the meanings ascribed to them in the Merger Agreement. Pursuant to the terms of the Merger Agreement, (i) Liquidia Merger Sub will merge with and into Liquidia in accordance with the General Corporation Law of the State of Delaware (the “DGCL”), with Liquidia continuing as the surviving corporation (the “Liquidia Merger”) and each share of common stock, par value $0.001 per share, of Liquidia (the “Liquidia Common Stock”) shall be converted into the right to receive one share of common stock, par value $0.001 per share, of HoldCo (the “HoldCo Common Stock”), (ii) RareGen Merge Sub will merge with and into RareGen in accordance with the DGCL, with RareGen continuing as the surviving corporation (the “RareGen Merger”, and together with the Liquidia Merger, the “Mergers”), and each common unit of RareGen (the “RareGen Common Units”) shall be converted into (x) the right to receive the Per Unit Closing Shares plus the Per Unit Holdback Shares, and (y) the contingent right to receive the Per Unit Net Sales Earnout Shares, if any, in accordance with Section 2.5 of the Merger Agreement plus the Per Unit Excess Cash (which, at your direction we have assumed to be zero for purposes of this opinion). The terms and conditions of the Mergers are more fully set forth in the Merger Agreement.

You have asked for our opinion as to whether the number of shares of HoldCo Common Stock to be received by stockholders of Liquidia in the Liquidia Merger pursuant to the Merger Agreement is fair, from a financial point of view, to the stockholders of Liquidia.

In arriving at our opinion, we have, among other things:

reviewed a draft dated June 26, 2020 of the Merger Agreement;

ii.

reviewed certain publicly available financial and other information about Liquidia;

iii.

reviewed certain information furnished to us by Liquidia management, relating to the business, operations and prospects of Liquidia, including financial forecasts and analyses under various business assumptions;

iv.

reviewed certain information furnished to us by Liquidia management, relating to the business, operations and prospects of RareGen, including financial forecasts and analyses under various business assumptions;

reviewed certain financial information furnished to us by RareGen management, relating to the

B-1

TABLE OF CONTENTS

business, operations and prospects of RareGen, including financial forecasts and analysis under various business assumptions, and held discussions with senior members of RareGen management about such matters;

vi.

reviewed information relating to certain financial and operational benefits and operating synergies (including the amount and timing thereof) anticipated by Liquidia management to result from the Mergers, and approved for our use by Liquidia (“Synergies”);

vii. considered the potential pro forma impact of the Mergers;

viii.

held discussions with members of senior management of Liquidia concerning the matters described in clauses (ii) through (vii) above;

ix.

compared the proposed financial terms of the Mergers with the publicly available financial terms of certain other transactions that we deemed relevant; and

conducted such other financial studies, analyses and investigations as we deemed appropriate.

In our review and analysis and in rendering this opinion, we have assumed and relied upon, but have not assumed any responsibility to independently investigate or verify, the accuracy and completeness of all financial and other information that was supplied or otherwise made available by Liquidia or that was publicly available to us (including, without limitation, the information described above), or that was otherwise reviewed by us. We have relied on assurances of the management of Liquidia that they are not aware of any facts or circumstances that would make such information inaccurate or misleading. In our review, we did not obtain any independent evaluation or appraisal of any of the assets or liabilities of, nor did we conduct a physical inspection of any of the properties or facilities of, Liquidia, RareGen or HoldCo, nor have we been furnished with any such evaluations or appraisals of such physical inspections, nor do we assume any responsibility to obtain any such evaluations or appraisals.

With respect to the financial forecasts provided to and, at your direction, examined by us, we note that projecting future results of any company is inherently subject to uncertainty. With respect to the Liquidia and RareGen forecasts prepared by Liquidia management and provided to us by Liquidia management, you have informed us, and we have assumed, that such financial forecasts were reasonably prepared on bases reflecting the best currently available estimates and good faith judgment of Liquidia management as to the future financial performance of Liquidia and RareGen. With respect to the future financial performance of HoldCo giving pro forma effect to the Mergers, at your direction and with your consent, we have assumed that the Synergies will be realized in the amounts and at the times projected. We express no opinion as to these financial forecasts or the assumptions on which they are made, including the Synergies. In addition, at your direction we have performed certain financial analysis using the financial forecasts prepared by management of RareGen. We express no opinion as to the financial forecasts prepared by management of RareGen or the assumptions on which they are made.

Our opinion is based on economic, monetary, regulatory, market and other conditions existing and which can be evaluated as of the date hereof. We expressly disclaim any undertaking or obligation to advise any person of any change in any fact or matter affecting our opinion of which we become aware after the date hereof.

We have made no independent investigation of any legal or accounting matters affecting Liquidia, RareGen or HoldCo, and we have assumed the correctness in all respects material to our analysis of all legal and accounting advice given to Liquidia and its Board of Directors, including, without limitation, advice as to the legal, accounting and tax consequences of the terms of, and transactions contemplated by, the Merger Agreement to Liquidia, RareGen and HoldCo. We have assumed that the final form of the Merger Agreement will be substantially similar to the last draft reviewed by us in all respects material to our opinion. We have assumed that the Mergers will be consummated in accordance with the terms of the Merger Agreement without waiver, modification or amendment of any term, condition or agreement. We have also assumed that in the course of obtaining the necessary regulatory or third party approvals, consents and releases for the Mergers, no delay, limitation, restriction or condition will be imposed that would have an adverse effect on Liquidia, RareGen or HoldCo or the contemplated benefits of the Mergers in any respect

TABLE OF CONTENTS

material to our opinion. We express no opinion as to the price shares of HoldCo Common Stock will trade at any future time.

It is understood that our opinion is for the use and benefit of the Board of Directors of Liquidia in its consideration of the transactions contemplated by the Merger Agreement, and our opinion does not address the relative merits of the transactions contemplated by the Merger Agreement as compared to any alternative transaction or opportunity that might be available to Liquidia, nor does it address the underlying business decision by Liquidia to engage in the transactions contemplated by the Merger Agreement. Our opinion does not take into account any Equity Financing that may be completed by Liquiida following the execution of the Merger Agreement. In addition, you have not asked us to address, and this opinion does not address, the fairness to, or any other consideration of, the holders of any class of securities, creditors or other constituencies of Liquidia. Our opinion has been authorized by the Fairness Committee of Jefferies LLC.

We have been engaged by Liquidia to act as financial advisor to Liquidia in connection with the transactions contemplated by the Merger Agreement and will receive a fee for our services. We also will be reimbursed for certain expenses reasonably incurred. Liquidia has agreed to indemnify us against certain liabilities arising out of or in connection with the services rendered and to be rendered by us under such engagement. In the past two years, we have provided financial advisory and financing services to Liquidia, including (i) acting as a bookrunner for Liquidia’s initial public offering of Liquidia Common Stock in July 2018, (ii) acting as a bookrunner in an offering of Liquidia Common Stock in March 2019, (iii) acting as a placement agent in a private placement of Liquidia Common Stock in December 2019, and (iv) acting as a placement agent for Liquidia’s ATM facility in December 2019-February 2020, for which we have received aggregate fees of less than $5.0 million. We maintain a market in the securities of Liquidia, and in the ordinary course of our business, we and our affiliates may trade or hold securities of Liquidia, RareGen, HoldCo and/or their respective affiliates for our own account and for the accounts of our customers and, accordingly, may at any time hold long or short positions in those securities. In addition, we may seek to, in the future, provide financial advisory and financing services to Liquidia, RareGen, HoldCo or entities that are affiliated with Liquidia, RareGen or HoldCo, for which we would expect to receive compensation. Our opinion may not be used or referred to by Liquidia, or quoted or disclosed to any person in any matter, without our prior written consent.

Based upon and subject to the foregoing, we are of the opinion that, as of the date hereof, the number of shares of HoldCo Common stock to be received by stockholders of Liquidia in the Liquidia Merger pursuant to the Merger Agreement is fair, from a financial point of view, to the stockholders of Liquidia.

Very truly yours,

Jefferies LLC

5. Shares Issuable Pursuant to Awards.

(a) Initial Share Pool. Subject to adjustments as provided in Section 10 of the Plan, the number of shares of Common Stock issuable pursuant to Awards that may be granted under the Plan shall equal 1,700,000 (the “Share Pool”).

(b) Adjustments to Share Pool. On and after the Effective Date, the Share Pool shall be adjusted, in addition to any adjustments to be made pursuant to Section 10 of the Plan, as follows:

(i) The Share Pool shall be increased automatically, without further action of the Board, on January 1st of each calendar year commencing after the Effective Date and ending on (and including) January 1, 2030, by a number of shares of Common Stock equal to the lesser of (A) four percent (4%) of the aggregate number of shares of Common Stock outstanding on December 31st of the immediately preceding calendar year, excluding for this purpose any such outstanding shares of Common Stock that were granted under this Plan and remain unvested and subject to forfeiture as of the relevant December 31st, or (B) a lesser number of shares of Common Stock determined by the Board or Compensation Committee prior to the relevant January 1st.

(ii) The Share Pool shall be reduced, on the date of grant, by one share for each share of Common Stock made subject to an Award granted under the Plan;

C-3

TABLE OF CONTENTS

is cancelled, forfeited, expired, terminated unearned or settled in cash, in any such case without the issuance of shares and by the number of shares of Common Stock used as a reference measure for any Award that are not issued upon settlement of such Award either due to a net settlement or otherwise;

(iv) The Share Pool shall be increased, on the forfeiture date, by the number of shares of Common Stock that are forfeited back to Liquidia Corporation after issuance due to a failure to meet an Award contingency or condition with respect to any Award or portion of an Award;

(vii) Notwithstanding the foregoing, the Share Pool will not be increased to include any shares of Common Stock issuable upon exercise of options granted under the Assumed Plans that expire or terminate without having been exercised in full.

(c) ISO Limit. Subject to adjustment pursuant to Section 10 of the Plan, the maximum number of shares of Common Stock that may be issued pursuant to stock options granted under the Plan that are intended to qualify as Incentive Stock Options within the meaning of Section 422 of the Code shall be equal to 10,000,000.

(d) Source of Shares. The shares of Common Stock with respect to which Awards may be made under the Plan shall be shares authorized for issuance under Liquidia Corporation’ charter but unissued, or issued and reacquired, including without limitation shares purchased in the open market or in private transactions.

(e) Non-Employee Director Award Limit. In addition, the Administrator may establish compensation for Non-Employee Directors from time to time, subject to the limitations in the Plan. The Administrator will from time to time determine the terms, conditions and amounts of all such Non-Employee Director compensation in its discretion and pursuant to the exercise of its business judgment, taking into account such factors, circumstances and considerations as it shall deem relevant from time to time, provided that the sum of any cash compensation and the grant date fair value of Awards (as determined in accordance with Financial Accounting Standards Board Accounting Standards Codification Topic 718, or any successor thereto) granted under the Plan to a Non-Employee Director as compensation for services as a Non-Employee Director during any calendar year of the Company may not exceed $500,000 for an annual grant, provided however, in a Non-Employee Director’s first year of service compensation for services may not exceed $1,000,000 (such limits, the “Director Limits”). The Administrator may make exceptions to this limit for individual Non-Employee directors in extraordinary circumstances, as the Administrator may determine in its discretion, provided that the Non-Employee Director receiving such additional compensation may not participate in the decision to award such compensation or in other compensation decisions involving Non-Employee Director.

6. Participation.

Participation in the Plan shall be open to all Eligible Individuals, as may be selected by the Administrator from time to time.

7. Awards.

(a) Awards, In General. The Administrator, in its sole discretion, shall establish the terms of all Awards granted under the Plan consistent with the terms of the Plan. Awards may be granted individually or in tandem with other types of Awards, concurrently with or with respect to outstanding Awards. All

C-4

TABLE OF CONTENTS

Awards are subject to the terms and conditions provided in the Award Agreement, which shall be delivered to the Participant receiving such Award upon, or as promptly as is reasonably practicable following, the grant of such Award. Unless otherwise specified by the Administrator, in its sole discretion, or otherwise provided in the Award Agreement, an Award shall not be effective unless the Award Agreement is signed or otherwise accepted by Liquidia Corporation and the Participant receiving the Award (including by electronic delivery and/or electronic signature).

(b) Stock Options.

(i) Grants. A stock option means a right to purchase a specified number of shares of Common Stock from Liquidia Corporation at a specified price during a specified period of time. The Administrator may from time to time grant to Eligible Individuals Awards of Incentive Stock Options or Nonqualified Options; provided, however, that Awards of Incentive Stock Options shall be limited to employees of Liquidia Corporation or of any current or hereafter existing “parent corporation” or “subsidiary corporation,” as defined in Sections 424(e) and 424(f) of the Code, respectively, of Liquidia Corporation, and any other Eligible Individuals who are eligible to receive Incentive Stock Options under the provisions of Section 422 of the Code. No stock option shall be an Incentive Stock Option unless so designated by the Administrator at the time of grant or in the applicable Award Agreement.

(ii) Exercise. Stock options shall be exercisable at such time or times and subject to such terms and conditions as shall be determined by the Administrator; provided, however, that Awards of stock options may not have a term in excess of ten years’ duration unless required otherwise by applicable law.

(iii) Termination of Service. Except as provided in the applicable Award Agreement or otherwise determined by the Administrator, to the extent stock options are not vested and exercisable, a Participant’s stock options shall be forfeited upon his or her Termination of Service.

(iv) Additional Terms and Conditions. The Administrator may, by way of the Award Agreement or otherwise, determine such other terms, conditions, restrictions, and/or limitations, if any, of any Award of stock options, provided they are not inconsistent with the Plan.

(c) Limitation on Reload Options. The Administrator shall not grant stock options under this Plan that contain a reload or replenishment feature pursuant to which a new stock option would be granted automatically upon receipt of delivery of Common Stock to Liquidia Corporation in payment of the exercise price or any tax withholding obligation under any other stock option.

(d) Stock Appreciation Rights.

(i) Grants. The Administrator may from time to time grant to Eligible Individuals Awards of stock appreciation rights. A stock appreciation right entitles the Participant to receive, subject to the provisions of the Plan and the Award Agreement, a payment having an aggregate value equal to the product of (i) the excess of (A) the Fair Market Value on the exercise date of one share of Common Stock over (B) the base price per share specified in the Award Agreement, times (ii) the number of shares specified by the stock appreciation right, or portion thereof, which is exercised. The base price per share specified in the Award Agreement shall not be less than the lower of the Fair Market Value on the date of grant or the exercise price of any tandem stock option to which the stock appreciation right is related, or with respect to stock appreciation rights that are granted in substitution of similar types of awards of a company acquired by Liquidia Corporation or a Subsidiary or with which Liquidia Corporation or a Subsidiary combines (whether in connection with a corporate transaction, such as a merger, combination, consolidation or acquisition of property or stock, or otherwise) such base price as is necessary to preserve the intrinsic value of such awards.

(ii) Exercise. Stock appreciation rights shall be exercisable at such time or times and subject to such terms and conditions as shall be determined by the Administrator; provided, however, that stock appreciation rights granted under the Plan may not have a term in excess of ten years’ duration unless required otherwise by applicable law. The applicable Award Agreement shall specify whether payment by Liquidia Corporation of the amount receivable upon any exercise of a stock appreciation right is to be made in cash or shares of Common Stock or a combination of both, or shall reserve to the Administrator or the Participant the right to make that determination prior to or upon the exercise of

C-5

TABLE OF CONTENTS

the stock appreciation right. If upon the exercise of a stock appreciation right a Participant is to receive a portion of such payment in shares of Common Stock, the number of shares shall be determined by dividing such portion by the Fair Market Value of a share of Common Stock on the exercise date. No fractional shares shall be used for such payment and the Administrator shall determine whether cash shall be given in lieu of such fractional shares or whether such fractional shares shall be eliminated.

(iii) Termination of Service. Except as provided in the applicable Award Agreement or otherwise determined by the Administrator, to the extent stock appreciation rights are not vested and exercisable, a Participant’s stock appreciation rights shall be forfeited upon his or her Termination of

(iv) Additional Terms and Conditions. The Administrator may, by way of the Award Agreement or otherwise, determine such other terms, conditions, restrictions, and/or limitations, if any, of any Award of stock appreciation rights, provided they are not inconsistent with the Plan.

(e) Repricing. Notwithstanding anything herein to the contrary, except in connection with a corporate transaction involving Liquidia Corporation (including, without limitation, any stock dividend, stock split, extraordinary cash dividend, recapitalization, reorganization, merger, consolidation, split-up, spin-off, combination, or exchange of shares), the terms of options and stock appreciation rights granted under the Plan may not be amended, after the date of grant, to reduce the exercise price of such options or stock appreciation rights, nor may outstanding options or stock appreciation rights be canceled in exchange for (i) cash, (ii) options or stock appreciation rights with an exercise price or base price that is less than the exercise price or base price of the original outstanding options or stock appreciation rights, or (iii) other Awards, unless such action is approved by Liquidia Corporation’ stockholders.

(f) Stock Awards.

(i) Grants. The Administrator may from time to time grant to Eligible Individuals Awards of unrestricted Common Stock or Restricted Stock (collectively, “Stock Awards”) on such terms and conditions, and for such consideration, including no consideration or such minimum consideration as the Administrator shall determine, subject to the limitations set forth in Section 7(b). Stock Awards shall be evidenced in such manner as the Administrator may deem appropriate, including via book-entry registration.

(ii) Vesting. Restricted Stock shall be subject to such vesting, restrictions on transferability and other restrictions, if any, and/or risk of forfeiture as the Administrator may impose at the date of grant or thereafter. The Restriction Period to which such vesting, restrictions and/or risk of forfeiture apply may lapse under such circumstances, including without limitation upon the attainment of Performance Goals, in such installments, or otherwise, as the Administrator may determine. Subject to the provisions of the Plan and the applicable Award Agreement, during the Restriction Period, the Participant shall not be permitted to sell, assign, transfer, pledge or otherwise encumber shares of Restricted Stock.

(iii) Rights of a Stockholder; Dividends. Except to the extent restricted under the Award Agreement relating to the Restricted Stock, a Participant granted Restricted Stock shall have all of the rights of a stockholder of Common Stock including, without limitation, the right to vote Restricted Stock. Cash dividends declared payable on Common Stock shall be paid, with respect to outstanding Restricted Stock, either as soon as practicable following the dividend payment date or deferred for payment to such later date as determined by the Administrator, and shall be paid in cash or as unrestricted shares of Common Stock having a Fair Market Value equal to the amount of such dividends or may be reinvested in additional shares of Restricted Stock as determined by the Administrator; provided, however, that dividends declared payable on Restricted Stock that is granted as a Performance Award shall be held by Liquidia Corporation and made subject to forfeiture at least until achievement of the applicable Performance Goal related to such shares of Restricted Stock. Stock distributed in connection with a stock split or stock dividend, and other property distributed as a dividend, shall be subject to restrictions and a risk of forfeiture to the same extent as the Restricted Stock with respect to which such Common Stock or other property has been distributed. As soon as is practicable following the date on which restrictions on any shares of Restricted Stock lapse, Liquidia Corporation shall deliver to the Participant the certificates for such shares or shall cause the shares to be registered in the Participant’s name in book-entry form, in either case with the restrictions removed, provided that the

C-6

TABLE OF CONTENTS

Participant shall have complied with all conditions for delivery of such shares contained in the Award Agreement or otherwise reasonably required by Liquidia Corporation.

(iv) Termination of Service. Except as provided in the applicable Award Agreement, upon Termination of Service during the applicable Restriction Period, Restricted Stock and any accrued but unpaid dividends that are at that time subject to restrictions shall be forfeited; provided that the Administrator may provide, by rule or regulation or in any Award Agreement, or may determine in any individual case, that restrictions or forfeiture conditions relating to Restricted Stock will be waived in whole or in part in the event of terminations resulting from specified causes, and the Administrator may in other cases waive in whole or in part the forfeiture of Restricted Stock.

(v) Additional Terms and Conditions. The Administrator may, by way of the Award Agreement or otherwise, determine such other terms, conditions, restrictions, and/or limitations, if any, of any Award of Restricted Stock, provided they are not inconsistent with the Plan.

(g) Stock Units.

(i) Grants. The Administrator may from time to time grant to Eligible Individuals Awards of unrestricted stock Units or Restricted Stock Units on such terms and conditions, and for such consideration, including no consideration or such minimum consideration as may be required by law, as the Administrator shall determine, subject to the limitations set forth in Section 7(b). Restricted Stock Units represent a contractual obligation by Liquidia Corporation to deliver a number of shares of Common Stock, an amount in cash equal to the Fair Market Value of the specified number of shares subject to the Award, or a combination of shares of Common Stock and cash, in accordance with the terms and conditions set forth in the Plan and any applicable Award Agreement.

(ii) Vesting and Payment. Restricted Stock Units shall be subject to such vesting, risk of forfeiture and/or payment provisions as the Administrator may impose at the date of grant. The Restriction Period to which such vesting and/or risk of forfeiture apply may lapse under such circumstances, including without limitation upon the attainment of Performance Goals, in such installments, or otherwise, as the Administrator may determine. Shares of Common Stock, cash or a combination of shares of Common Stock and cash, as applicable, payable in settlement of Restricted Stock Units shall be delivered to the Participant as soon as administratively practicable, but no later than 30 days, after the date on which payment is due under the terms of the Award Agreement provided that the Participant shall have complied with all conditions for delivery of such shares or payment contained in the Award Agreement or otherwise reasonably required by Liquidia Corporation, or in accordance with an election of the Participant, if the Administrator so permits, that meets the requirements of Section 409A of the Code.

(iii) No Rights of a Stockholder; Dividend Equivalents. Until shares of Common Stock are issued to the Participant in settlement of stock Units, the Participant shall not have any rights of a stockholder of Liquidia Corporation with respect to the stock Units or the shares issuable thereunder. The Administrator may grant to the Participant the right to receive Dividend Equivalents on stock Units, on a current, reinvested and/or restricted basis, subject to such terms as the Administrator may determine provided, however, that Dividend Equivalents payable on stock Units that are granted as a Performance Award shall, rather than be paid on a current basis, be accrued and made subject to forfeiture at least until achievement of the applicable Performance Goal related to such stock Units.

(iv) Termination of Service. Upon Termination of Service during the applicable deferral period or portion thereof to which forfeiture conditions apply, or upon failure to satisfy any other conditions precedent to the delivery of shares of Common Stock or cash to which such Restricted Stock Units relate, all Restricted Stock Units and any accrued but unpaid Dividend Equivalents with respect to such Restricted Stock Units that are then subject to deferral or restriction shall be forfeited; provided that the Administrator may provide, by rule or regulation or in any Award Agreement, or may determine in any individual case, that restrictions or forfeiture conditions relating to Restricted Stock Units will be waived in whole or in part in the event of termination resulting from specified causes, and the Administrator may in other cases waive in whole or in part the forfeiture of Restricted Stock Units.

C-7

TABLE OF CONTENTS

(v) Additional Terms and Conditions. The Administrator may, by way of the Award Agreement or otherwise, determine such other terms, conditions, restrictions, and/or limitations, if any, of any Award of stock Units, provided they are not inconsistent with the Plan.

(h) Performance Shares and Performance Units.

(i) Grants. The Administrator may from time to time grant to Eligible Individuals Awards in the form of Performance Shares and Performance Units. Performance Shares, as that term is used in this Plan, shall refer to shares of Common Stock or Units that are expressed in terms of Common Stock, the issuance, vesting, lapse of restrictions on or payment of which is contingent on performance as measured against predetermined objectives over a specified Performance Period. Performance Units, as that term is used in this Plan, shall refer to dollar-denominated Units valued by reference to designated criteria established by the Administrator, other than Common Stock, the issuance, vesting, lapse of restrictions on or payment of which is contingent on performance as measured against predetermined objectives over a specified Performance Period. The applicable Award Agreement shall specify whether Performance Shares and Performance Units will be settled or paid in cash or shares of Common Stock or a combination of both, or shall reserve to the Administrator or the Participant the right to make that determination prior to or at the payment or settlement date.

(ii) Performance Criteria. The Administrator shall, prior to or at the time of grant, condition the grant, vesting or payment of, or lapse of restrictions on, an Award of Performance Shares or Performance Units upon (A) the attainment of Performance Goals during a Performance Period or (B) the attainment of Performance Goals and the continued service of the Participant. The length of the Performance Period, the Performance Goals to be achieved during the Performance Period, and the measure of whether and to what degree such Performance Goals have been attained shall be conclusively determined by the Administrator in the exercise of its absolute discretion. Performance Goals may include minimum, maximum and target levels of performance, with the size of the Award or payout of Performance Shares or Performance Units or the vesting or lapse of restrictions with respect thereto based on the level attained. Performance Goals may be applied on a per share or absolute basis and relative to one or more Performance Metrics, or any combination thereof, and may be measured pursuant to U.S. generally accepted accounting principles (“GAAP”), non-GAAP or other objective standards in a manner consistent with Liquidia Corporation’ or its Subsidiary’s established accounting policies, all as the Administrator shall determine at the time the Performance Goals for a Performance Period are established. The Administrator may, in its sole discretion, provide that one or more objectively determinable adjustments shall be made to the manner in which one or more of the Performance Goals is to be calculated or measured to take into account, or ignore, one or more of the following: (1) items related to a change in accounting principle; (2) items relating to financing activities; (3) expenses for restructuring or productivity initiatives; (4) other non-operating items; (5) items related to acquisitions; (6) items attributable to the business operations of any entity acquired by the Company during the Performance Period; (7) items related to the sale or disposition of a business or segment of a business; (8) items related to discontinued operations that do not qualify as a segment of a business under U.S. generally accepted accounting principles; (9) items attributable to any stock dividend, stock split, combination or exchange of stock occurring during the Performance Period; (10) any other items of significant income or expense which are determined to be appropriate adjustments; (11) items relating to unusual or extraordinary corporate transactions, events or developments, (12) items related to amortization of acquired intangible assets; (13) items that are outside the scope of the Company’s core, on-going business activities; (14) changes in foreign currency exchange rates; (15) items relating to changes in tax laws; (16) certain identified expenses (including, but not limited to, cash bonus expenses, incentive expenses and acquisition-related transaction and integration expenses); (17) items relating to asset impairment charges; (18) items relating to gains or unusual or nonrecurring events or changes in applicable law, accounting principles or business conditions, or (19) or any other items selected by the Administrator. Shares or Performance Units shall be settled as and when the Award vests or at a later time specified in the Award Agreement or in accordance with an election of the Participant, if the Administrator so permits, that meets the requirements of Section 409A of the Code.

(iii) Additional Terms and Conditions. The Administrator may, by way of the Award Agreement or otherwise, determine such other terms, conditions, restrictions, and/or limitations, if any, of any Award of Performance Shares or Performance Units, provided they are not inconsistent with the Plan.

C-8

TABLE OF CONTENTS

(i) Other Stock-Based Awards. The Administrator may from time to time grant to Eligible Individuals Awards in the form of Other Stock-Based Awards. Other Stock-Based Awards in the form of Dividend Equivalents may be (A) awarded on a free-standing basis or in connection with another Award other than a stock option or stock appreciation right, (B) paid currently or credited to an account for the Participant, including the reinvestment of such credited amounts in Common Stock equivalents, to be paid on a deferred basis, and (C) settled in cash or Common Stock as determined by the Administrator; provided, however, that Dividend Equivalents payable on Other Stock-Based Awards that are granted as a Performance Award shall, rather than be paid on a current basis, be accrued and made subject to forfeiture at least until achievement of the applicable Performance Goal related to such Other Stock- Based Awards. Any such settlements, and any such crediting of Dividend Equivalents, may be subject to such conditions, restrictions and contingencies as the Administrator shall establish.

(j) Awards to Participants Outside the United States. The Administrator may grant Awards to Eligible Individuals who are foreign nationals, who are located outside the United States or who are not compensated from a payroll maintained in the United States, or who are otherwise subject to (or could cause Liquidia Corporation or a Subsidiary to be subject to) tax, legal or regulatory provisions of countries or jurisdictions outside the United States, on such terms and conditions different from those specified in the Plan as may, in the judgment of the Administrator, be necessary or desirable in order that any such Award shall conform to laws, regulations, and customs of the country or jurisdiction in which the Participant is then resident or primarily employed or to foster and promote achievement of the purposes of the Plan.

(k) Limitation on Dividend Reinvestment and Dividend Equivalents. Reinvestment of dividends in additional Restricted Stock at the time of any dividend payment, and the payment of shares of Common Stock with respect to dividends to Participants holding Awards of stock Units, shall only be permissible if sufficient shares are available under the Share Pool for such reinvestment or payment (taking into account then outstanding Awards). In the event that sufficient shares are not available under the Share Pool for such reinvestment or payment, such reinvestment or payment shall be made in the form of a grant of stock Units equal in number to the shares of Common Stock that would have been obtained by such payment or reinvestment, the terms of which stock Units shall provide for settlement in cash and for Dividend Equivalent reinvestment in further stock Units on the terms contemplated by this Section 7(k).

8. Withholding of Taxes.

Participants and holders of Awards shall pay to Liquidia Corporation or its Affiliate, or make arrangements satisfactory to the Administrator for payment of, any Tax Withholding Obligation in respect of Awards granted under the Plan no later than the date of the event creating the tax or social insurance contribution liability. The obligations of Liquidia Corporation under the Plan shall be conditional on such payment or arrangements. Unless otherwise determined by the Administrator, Tax Withholding Obligations may be settled in whole or in part with shares of Common Stock, including unrestricted outstanding shares surrendered to Liquidia Corporation and unrestricted shares that are part of the Award that gives rise to the Tax Withholding Obligation, having a Fair Market Value on the date of surrender or withholding equal to the statutory minimum amount (or such greater amount permitted under FASB Accounting Standards Codification Topic 718, Compensation — Stock Compensation, for equity-classified awards) required to be withheld for tax or social insurance contribution purposes, all in accordance with such procedures as the Administrator establishes. Liquidia Corporation or its Affiliate may deduct, to the extent permitted by law, any such Tax Withholding Obligations from any payment of any kind otherwise due to the Participant or holder of an Award.

9. Transferability of Awards.

(a) General Nontransferability Absent Administrator Permission. Except as otherwise determined by the Administrator, and in any event in the case of an Incentive Stock Option or a tandem stock appreciation right granted with respect to an Incentive Stock Option, no Award granted under the Plan shall be transferable by a Participant otherwise than by will or the laws of descent and distribution. The Administrator shall not permit any transfer of an Award for value. An Award may be exercised during the lifetime of the Participant, only by the Participant or, during the period the Participant is under a legal disability, by the Participant’s guardian or legal representative, unless otherwise determined by the

C-9

TABLE OF CONTENTS

Administrator. Awards granted under the Plan shall not be subject in any manner to alienation, anticipation, sale, transfer, assignment, pledge, or encumbrance, except as otherwise determined by the Administrator; provided, however, that the restrictions in this sentence shall not apply to the shares of Common Stock received in connection with an Award after the date that the restrictions on transferability of such shares set forth in the applicable Award Agreement have lapsed. Nothing in this paragraph shall be interpreted or construed as overriding the terms of any Liquidia Corporation stock ownership or retention policy, now or hereafter existing, that may apply to the Participant or shares of Common Stock received under an Award.

(b) Administrator Discretion to Permit Transfers Other Than For Value. Except as otherwise restricted by applicable law, the Administrator may, but need not, permit an Award, other than an Incentive Stock Option or a tandem stock appreciation right granted with respect to an Incentive Stock Option, to be transferred to a Participant’s Family Member (as defined below) as a gift or pursuant to a domestic relations order in settlement of marital property rights. The Administrator shall not permit any transfer of an Award for value. For purposes of this Section 9, “Family Member” means any child, stepchild, grandchild, parent, stepparent, grandparent, spouse, former spouse, sibling, niece, nephew, mother-in-law, father-in-law, son-in-law, daughter-in-law, brother-in-law, or sister-in-law, including adoptive relationships, any person sharing the Participant’s household (other than a tenant or employee), a trust in which these persons have more than fifty percent of the beneficial interest, a foundation in which these persons (or the Participant) control the management of assets, and any other entity in which these persons (or the Participant) own more than fifty percent (50%) of the voting interests. The following transactions are not prohibited transfers for value: (i) a transfer under a domestic relations order in settlement of marital property rights; and (ii) a transfer to an entity in which more than fifty percent of the voting interests are owned by Family Members (or the Participant) in exchange for an interest in that entity.

10. Adjustments for Corporate Transactions and Other Events.

(a) Mandatory Adjustments. In the event of a merger, consolidation, stock rights offering, statutory share exchange or similar event affecting Liquidia Corporation (each, a “Corporate Event”) or a stock dividend, stock split, reverse stock split, separation, spinoff, reorganization, extraordinary dividend of cash or other property, share combination or subdivision, recapitalization, capital reduction distribution, or similar event affecting the capital structure of Liquidia Corporation (each, a “Share Change”) that occurs at any time after the Effective Date (including any such Corporate Event or Share Change that occurs after such adoption and coincident with or prior to the Effective Date), the Administrator shall make equitable and appropriate substitutions or proportionate adjustments to (i) the aggregate number and kind of shares of Common Stock or other securities on which Awards under the Plan may be granted to Eligible Individuals, (ii) the maximum number of shares of Common Stock or other securities that may be issued with respect to Incentive Stock Options granted under the Plan, (iv) the number of shares of Common Stock or other securities covered by each outstanding Award and the exercise price, base price or other price per share, if any, and other relevant terms of each outstanding Award, and (v) all other numerical limitations relating to Awards, whether contained in this Plan or in Award Agreements; provided, however, that any fractional shares resulting from any such adjustment shall be eliminated.

(b) Discretionary Adjustments. In the case of Corporate Events, the Administrator may make such other adjustments to outstanding Awards as it determines to be appropriate and desirable, which adjustments may include, without limitation, (i) the cancellation of outstanding Awards in exchange for payments of cash, securities or other property or a combination thereof having an aggregate value equal to the value of such Awards, as determined by the Administrator in its sole discretion (it being understood that in the case of a Corporate Event with respect to which stockholders of Liquidia Corporation receive consideration other than publicly traded equity securities of the ultimate surviving entity, any such determination by the Administrator that the value of a stock option or stock appreciation right shall for this purpose be deemed to equal the excess, if any, of the value of the consideration being paid for each share of Common Stock pursuant to such Corporate Event over the exercise price or base price of such stock option or stock appreciation right shall conclusively be deemed valid and that any stock option or stock appreciation right may be cancelled for no consideration upon a Corporate Event if its exercise price or base price equals or exceeds the value of the consideration being paid for each share of Common Stock pursuant to such Corporate Event), (ii) the substitution of securities or other property (including, without limitation, cash or other securities of Liquidia Corporation and securities of entities other than Liquidia Corporation) for

C-10

TABLE OF CONTENTS

the shares of Common Stock subject to outstanding Awards, and (iii) the substitution of equivalent awards, as determined in the sole discretion of the Administrator, of the surviving or successor entity or a parent thereof (“Substitute Awards”).

(c) Adjustments to Performance Goals. The Administrator may, in its discretion, adjust the Performance Goals applicable to any Awards to reflect any unusual or non-recurring events and other extraordinary items, impact of charges for restructurings, discontinued operations and the cumulative effects of accounting or tax changes, each as defined by generally accepted accounting principles or as identified in Liquidia Corporation’ consolidated financial statements, notes to the consolidated financial statements, management’s discussion and analysis or other Liquidia Corporation filings with the Securities and Exchange Commission. If the Administrator determines that a change in the business, operations, corporate structure or capital structure of Liquidia Corporation or the applicable subsidiary, business segment or other operational unit of Liquidia Corporation or any such entity or segment, or the manner in which any of the foregoing conducts its business, or other events or circumstances, render the Performance Goals to be unsuitable, the Administrator may modify such Performance Goals or the related minimum acceptable level of achievement, in whole or in part, as the Administrator deems appropriate and equitable.

(d) Statutory Requirements Affecting Adjustments. Notwithstanding the foregoing: (A) any adjustments made pursuant to Section 10 to Awards that are considered “deferred compensation” within the meaning of Section 409A of the Code shall be made in compliance with the requirements of Section 409A of the Code; (B) any adjustments made pursuant to Section 10 to Awards that are not considered “deferred compensation” subject to Section 409A of the Code shall be made in such a manner as to ensure that after such adjustment, the Awards either (1) continue not to be subject to Section 409A of the Code or (2) comply with the requirements of Section 409A of the Code; (C) in any event, the Administrator shall not have the authority to make any adjustments pursuant to Section 10 to the extent the existence of such authority would cause an Award that is not intended to be subject to Section 409A of the Code at the date of grant to be subject thereto; and (D) any adjustments made pursuant to Section 10 to Awards that are Incentive Stock Options shall be made in compliance with the requirements of Section 424(a) of the Code.

(e) Dissolution or Liquidation. Unless the Administrator determines otherwise, all Awards outstanding under the Plan shall terminate upon the dissolution or liquidation of Liquidia Corporation.

11. Change in Control Provisions.

(a) Termination of Awards. Notwithstanding the provisions of Section 11(b), in the event that any transaction resulting in a Change in Control occurs, outstanding Awards will terminate upon the effective time of such Change in Control unless provision is made in connection with the transaction for the continuation or assumption of such Awards by, or for the issuance therefor of Substitute Awards of, the surviving or successor entity or a parent thereof. Solely with respect to Awards that will terminate as a result of the immediately preceding sentence and except as otherwise provided in the applicable Award Agreement:

(i) the outstanding Awards of stock options and stock appreciation rights that will terminate upon the effective time of the Change in Control shall, immediately before the effective time of the Change in Control, become fully exercisable and the holders of such Awards will be permitted, immediately before the Change in Control, to exercise the Awards;

(ii) the outstanding shares of Restricted Stock the vesting or restrictions on which are then solely time-based and not subject to achievement of Performance Goals shall, immediately before the effective time of the Change in Control, become fully vested, free of all transfer and lapse restrictions and free of all risks of forfeiture;

(iii) the outstanding shares of Restricted Stock the vesting or restrictions on which are then subject to and pending achievement of Performance Goals shall, immediately before the effective time of the Change in Control and unless the Award Agreement provides for vesting or lapsing of restrictions in a greater amount upon the occurrence of a Change in Control, become vested, free of transfer and lapse restrictions and risks of forfeiture in such amounts as if the applicable Performance Goals for the unexpired Performance Period had been achieved at the target level set forth in the applicable Award Agreement;

C-11

TABLE OF CONTENTS

(iv) the outstanding Restricted Stock Units, Performance Shares and Performance Units the vesting, earning or settlement of which is then solely time-based and not subject to or pending achievement of Performance Goals shall, immediately before the effective time of the Change in Control, become fully earned and vested and shall be settled in cash or shares of Common Stock (consistent with the terms of the Award Agreement after taking into account the effect of the Change in Control transaction on the shares) as promptly as is practicable, subject to any applicable limitations imposed thereon by Section 409A of the Code; and

(v) the outstanding Restricted Stock Units, Performance Shares and Performance Units the vesting, earning or settlement of which is then subject to and pending achievement of Performance Goals shall, immediately before the effective time of the Change in Control and unless the Award Agreement provides for vesting, earning or settlement in a greater amount upon the occurrence of a Change in Control, become vested and earned in such amounts as if the applicable Performance Goals for the unexpired Performance Period had been achieved at the target level set forth in the applicable Award Agreement and shall be settled in cash or shares of Common Stock (consistent with the terms of the Award Agreement after taking into account the effect of the Change in Control transaction on the shares) as promptly as is practicable, subject to any applicable limitations imposed thereon by Section 409A of the Code.

Implementation of the provisions of this Section 11(a) shall be conditioned upon consummation of the Change in Control.

(b) Continuation, Assumption or Substitution of Awards. The Administrator may specify, on or after the date of grant, in an award agreement or amendment thereto, the consequences of a Participant’s Termination of Service that occurs coincident with or following the occurrence of a Change in Control, if a Change in Control occurs under which provision is made in connection with the transaction for the continuation or assumption of outstanding Awards by, or for the issuance therefor of Substitute Awards of, the surviving or successor entity or a parent thereof.

(c) Other Permitted Actions. In the event that any transaction resulting in a Change in Control occurs, the Administrator may take any of the actions set forth in Section 10 with respect to any or all Awards granted under the Plan.

(d) Section 409A Savings Clause. Notwithstanding the foregoing, if any Award is considered to be a “nonqualified deferred compensation plan” within the meaning of Section 409A of the Code, this Section 11 shall apply to such Award only to the extent that its application would not result in the imposition of any tax or interest or the inclusion of any amount in income under Section 409A of the Code.

12. Substitution of Awards in Mergers and Acquisitions.

Awards may be granted under the Plan from time to time in substitution for assumed awards held by employees, officers, or directors of entities who become employees, officers, or directors of Liquidia Corporation or a Subsidiary as the result of a merger or consolidation of the entity for which they perform services with Liquidia Corporation or a Subsidiary, or the acquisition by Liquidia Corporation of the assets or stock of the such entity. The terms and conditions of any Awards so granted may vary from the terms and conditions set forth herein to the extent that the Administrator deems appropriate at the time of grant to conform the Awards to the provisions of the assumed awards for which they are substituted and to preserve their intrinsic value as of the date of the merger, consolidation or acquisition transaction. To the extent permitted by applicable law and marketplace or listing rules of the primary securities market or exchange on which the Common Stock is listed or admitted for trading, any available shares under a stockholder-approved plan of an acquired company (as appropriately adjusted to reflect the transaction) may be used for Awards granted pursuant to this Section 12 and, upon such grant, shall not reduce the Share Pool.

13. Compliance with Securities Laws; Listing and Registration.

(a) The obligation of Liquidia Corporation to sell or deliver Common Stock with respect to any Award granted under the Plan shall be subject to all applicable laws, rules and regulations, including all

C-12

TABLE OF CONTENTS

applicable federal, state securities laws, and the obtaining of all such approvals by governmental agencies as may be deemed necessary or appropriate by the Administrator. If at any time the Administrator determines that the delivery of Common Stock under the Plan is or may be unlawful under the laws of any applicable jurisdiction, or Federal, state or foreign (non-United States) securities laws, the right to exercise an Award or receive shares of Common Stock pursuant to an Award shall be suspended until the Administrator determines that such delivery is lawful. If at any time the Administrator determines that the delivery of Common Stock under the Plan would or may violate the rules of any exchange on which Liquidia Corporation’ securities are then listed for trade, the right to exercise an Award or receive shares of Common Stock pursuant to an Award shall be suspended until the Administrator determines that such delivery would not violate such rules. If the Administrator determines that the exercise or nonforfeitability of, or delivery of benefits pursuant to, any Award would violate any applicable provision of securities laws or the listing requirements of any stock exchange upon which any of Liquidia Corporation’ equity securities are listed, then the Administrator may postpone any such exercise, nonforfeitability or delivery, as applicable, but Liquidia Corporation shall use all reasonable efforts to cause such exercise, nonforfeitability or delivery to comply with all such provisions at the earliest practicable date.

(b) Each Award is subject to the requirement that, if at any time the Administrator determines, in its absolute discretion, that the listing, registration or qualification of Common Stock issuable pursuant to the Plan is required by any securities exchange or under any state, federal or foreign (non-United States) law, or the consent or approval of any governmental regulatory body is necessary or desirable as a condition of, or in connection with, the grant of an Award or the issuance of Common Stock, no such Award shall be granted or payment made or Common Stock issued, in whole or in part, unless listing, registration, qualification, consent or approval has been effected or obtained free of any conditions not acceptable to the Administrator.

(c) In the event that the disposition of Common Stock acquired pursuant to the Plan is not covered by a then current registration statement under the Securities Act of 1933, as amended (the “Securities Act”), and is not otherwise exempt from such registration, such Common Stock shall be restricted against transfer to the extent required by the Securities Act or regulations thereunder, and the Administrator may require a person receiving Common Stock pursuant to the Plan, as a condition precedent to receipt of such Common Stock, to represent to Liquidia Corporation in writing that the Common Stock acquired by such person is acquired for investment only and not with a view to distribution and that such person will not dispose of the Common Stock so acquired in violation of Federal, state or foreign securities laws and furnish such information as may, in the opinion of counsel for the Company, be appropriate to permit the Company to issue the Common Stock in compliance with applicable Federal, state or foreign securities laws.

14. Section 409A Compliance.

It is the intention of Liquidia Corporation that any Award that constitutes a “nonqualified deferred compensation plan” within the meaning of Section 409A of the Code shall comply in all respects with the requirements of Section 409A of the Code to avoid the imposition of any tax or interest or the inclusion of any amount in income pursuant to Section 409A of the Code, and the terms of each such Award shall be construed, administered and deemed amended, if applicable, in a manner consistent with this intention. Notwithstanding the foregoing, neither Liquidia Corporation nor any of its Affiliates nor any of its or their directors, officers, employees, agents or other service providers will be liable for any taxes, penalties or interest imposed on any Participant or other person with respect to any amounts paid or payable (whether in cash, shares of Common Stock or other property) under any Award, including any taxes, penalties or interest imposed under or as a result of Section 409A of the Code. Any payments described in an Award that are due within the “short term deferral period” as defined in Section 409A of the Code shall not be treated as deferred compensation unless applicable law requires otherwise. For purposes of any Award, each amount to be paid or benefit to be provided to a Participant that constitutes deferred compensation subject to Section 409A of the Code shall be construed as a separate identified payment for purposes of Section 409A of the Code. For purposes of Section 409A of the Code, the payment of Dividend Equivalents under any Award shall be construed as earnings and the time and form of payment of such Dividend Equivalents shall be treated separately from the time and form of payment of the underlying Award. Notwithstanding any other provision of the Plan to the contrary, with respect to any Award that constitutes a “nonqualified deferred compensation plan” within the meaning of Section 409A of the Code, any

C-13

TABLE OF CONTENTS

payments (whether in cash, shares of Common Stock or other property) to be made with respect to the Award that become payable on account of the Participant’s separation from service, within the meaning of Section 409A of the Code, while the Participant is a “specified employee” (as determined in accordance with the uniform policy adopted by the Administrator with respect to all of the arrangements subject to Section 409A of the Code maintained by Liquidia Corporation and its Affiliates) and which would otherwise be paid within six months after the Participant’s separation from service shall be accumulated (without interest) and paid on the first day of the seventh month following the Participant’s separation from service or, if earlier, within 15 days after the appointment of the personal representative or executor of the Participant’s estate following the Participant’s death. Notwithstanding anything in the Plan or an Award Agreement to the contrary, in no event shall the Administrator exercise its discretion to accelerate the payment or settlement of an Award where such payment or settlement constitutes deferred compensation within the meaning of Code section 409A unless, and solely to the extent that, such accelerated payment or settlement is permissible under Treasury Regulation section 1.409A-3(j)(4).

15. Plan Duration; Amendment and Discontinuance.

(a) Plan Duration. The Plan shall remain in effect, subject to the right of the Board or the Compensation Committee to amend or terminate the Plan at any time, until the earlier of (a) the earliest date as of which all Awards granted under the Plan have been satisfied in full or terminated and no shares of Common Stock approved for issuance under the Plan remain available to be granted under new Awards or (b) June 27, 2030. No Awards shall be granted under the Plan after such termination date. Subject to other applicable provisions of the Plan, all Awards made under the Plan on or before June 27, 2030 or such earlier termination of the Plan, shall remain in effect until such Awards have been satisfied or terminated in accordance with the Plan and the terms of such Awards.

(b) Amendment and Discontinuance of the Plan. The Board or the Compensation Committee may amend, alter or discontinue the Plan, but no amendment, alteration or discontinuation shall be made which would materially impair the rights of a Participant with respect to a previously granted Award without such Participant’s consent, except such an amendment made to comply with applicable law or rule of any securities exchange or market on which the Common Stock is listed or admitted for trading or to prevent adverse tax or accounting consequences to Liquidia Corporation or the Participant. Notwithstanding the foregoing, no such amendment shall be made without the approval of Liquidia Corporation’ stockholders to the extent such amendment would (A) materially increase the benefits accruing to Participants under the Plan, (B) materially increase the number of shares of Common Stock which may be issued under the Plan or to a Participant, (C) materially expand the eligibility for participation in the Plan, (D) eliminate or modify the prohibition set forth in Section 7(e) on repricing of stock options and stock appreciation rights, (E) lengthen the maximum term or lower the minimum exercise price or base price permitted for stock options and stock appreciation rights, or (F) modify the prohibition on the issuance of reload or replenishment options. Except as otherwise determined by the Board or Compensation Committee, termination of the Plan shall not affect the Administrator’s ability to exercise the powers granted to it hereunder with respect to Awards granted under the Plan prior to the date of such termination.

(c) Amendment of Awards. Subject to Section 7(e), the Administrator may unilaterally amend the terms of any Award theretofore granted, but no such amendment shall materially impair the rights of any Participant with respect to an Award without the Participant’s consent, except such an amendment made to cause the Plan or Award to comply with applicable law, applicable rule of any securities exchange on which the Common Stock is listed or admitted for trading, or to prevent adverse tax or accounting consequences for the Participant or the Company or any of its Affiliates. For purposes of the foregoing sentence, an amendment to an Award that results in a change in the tax consequences of the Award to the Participant shall not be considered to be a material impairment of the rights of the Participant and shall not require the Participant’s consent.

16. General Provisions.

(a) Non-Guarantee of Employment or Service. Nothing in the Plan or in any Award Agreement thereunder shall confer any right on an individual to continue in the service of Liquidia Corporation or any Affiliate or shall interfere in any way with the right of Liquidia Corporation or any Affiliate to terminate

C-14

TABLE OF CONTENTS

such service at any time with or without cause or notice and whether or not such termination results in (i) the failure of any Award to vest or become payable; (ii) the forfeiture of any unvested or vested portion of any Award; and/or (iii) any other adverse effect on the individual’s interests under any Award or the Plan. No person, even though deemed an Eligible Individual, shall have a right to be selected as a Participant, or, having been so selected, to be selected again as a Participant. To the extent that an Eligible Individual who is an employee of a Subsidiary receives an Award under the Plan, that Award shall in no event be understood or interpreted to mean that Liquidia Corporation is the Participant’s employer or that the Participant has an employment relationship with Liquidia Corporation.

(b) No Trust or Fund Created. Neither the Plan nor any Award shall create or be construed to create a trust or separate fund of any kind or a fiduciary relationship between Liquidia Corporation and a Participant or any other person. To the extent that any Participant or other person acquires a right to receive payments from Liquidia Corporation pursuant to an Award, such right shall be no greater than the right of any unsecured general creditor of Liquidia Corporation.

(c) Status of Awards. Awards shall be special incentive payments to the Participant and shall not be taken into account in computing the amount of salary or compensation of the Participant for purposes of determining any pension, retirement, death, severance or other benefit under (a) any pension, retirement, profit-sharing, bonus, insurance, severance or other employee benefit plan of Liquidia Corporation or any Affiliate now or hereafter in effect under which the availability or amount of benefits is related to the level of compensation or (b) any agreement between (i) Liquidia Corporation or any Affiliate and (ii) the Participant, except as such plan or agreement shall otherwise expressly provide.

(d) Subsidiary Employees. In the case of a grant of an Award to an Eligible Individual who provides services to any Subsidiary, Liquidia Corporation may, if the Administrator so directs, issue or transfer the shares of Common Stock, if any, covered by the Award to the Subsidiary, for such lawful consideration as the Administrator may specify, upon the condition or understanding that the Subsidiary will transfer the shares of Common Stock to the Eligible Individual in accordance with the terms of the Award specified by the Administrator pursuant to the provisions of the Plan. All shares of Common Stock underlying Awards that are forfeited or canceled after such issue or transfer of shares to the Subsidiary shall revert to Liquidia Corporation.

(e) Governing Law and Interpretation. The validity, construction and effect of the Plan, of Award Agreements entered into pursuant to the Plan, and of any rules, regulations, determinations or decisions made by the Administrator relating to the Plan or such Award Agreements, and the rights of any and all persons having or claiming to have any interest therein or thereunder, shall be determined exclusively in accordance with applicable United States federal laws and the laws of the State of Delaware, without regard to its conflict of laws principles. The captions of the Plan are not part of the provisions hereof and shall have no force or effect. Except where the context otherwise requires: (i) the singular includes the plural and vice versa; (ii) a reference to one gender includes other genders; (iii) a reference to a person includes a natural person, partnership, corporation, association, governmental or local authority or agency or other entity; and (iv) a reference to a statute, ordinance, code or other law includes regulations and other instruments under it and consolidations, amendments, re-enactments or replacements of any of them.

(f) Use of English Language. The Plan, each Award Agreement, and all other documents, notices and legal proceedings entered into, given or instituted pursuant to an Award shall be written in English, unless otherwise determined by the Administrator. If a Participant receives an Award Agreement, a copy of the Plan or any other documents related to an Award translated into a language other than English, and if the meaning of the translated version is different from the English version, the English version shall control.

(g) Recovery of Amounts Paid. Except as otherwise provided by the Administrator, Awards granted under the Plan shall be subject to any and all policies, guidelines, codes of conduct, or other agreement or arrangement adopted by the Board or Compensation Committee with respect to the recoupment, recovery or clawback of compensation (collectively, the “Recoupment Policy”) and/or to any provisions set forth in the applicable Award Agreement under which Liquidia Corporation may recover from current and former Participants any amounts paid or shares of Common Stock issued under an Award and any proceeds therefrom under such circumstances as the Administrator determines appropriate. The Administrator may apply the Recoupment Policy to Awards granted before the policy is adopted to the extent required by

C-15

TABLE OF CONTENTS

applicable law or rule of any securities exchange or market on which shares of Common Stock are listed or admitted for trading, as determined by the Administrator in its sole discretion.

17. Glossary.

Under this Plan, except where the context otherwise indicates, the following definitions apply:

“Administrator” means the Compensation Committee, or such other committee(s) of director(s) duly appointed by the Board or the Compensation Committee to administer the Plan or delegated limited authority to perform administrative actions under the Plan, and having such powers as shall be specified by the Board or the Compensation Committee; provided, however, that at any time the Board may serve as the Administrator in lieu of or in addition to the Compensation Committee or such other committee(s) of director(s) to whom administrative authority has been delegated. With respect to any Award to which Section 16 of the Exchange Act applies, the Administrator shall consist of either the Board or a committee of the Board, which committee shall consist of three or more directors, each of whom is intended to be, to the extent required by Rule 16b-3 of the Exchange Act, a “non-employee director” as defined in Rule 16b-3 of the Exchange Act and an “independent director” to the extent required by the rules of the national securities exchange that is the principal trading market for the Common Stock, provided that, with respect to Awards made to a member of the Board who is not an employee of the Company, Administrator means the Board. Any member of the Administrator who does not meet the foregoing requirements shall abstain from any decision regarding an Award and shall not be considered a member of the Administrator to the extent required to comply with Rule 16b-3 of the Exchange Act.

“Adoption Date” means the date the Plan is adopted by the Board.

“Affiliate” means any entity, whether now or hereafter existing, which controls, is controlled by, or is under common control with, Liquidia Corporation or any successor to Liquidia Corporation. For this purpose, “control” (including the correlative meanings of the terms “controlled by” and “under common control with”) shall mean ownership, directly or indirectly, of 50% or more of the total combined voting power of all classes of voting securities issued by such entity, or the possession, directly or indirectly, of the power to direct the management and policies of such entity, by contract or otherwise.

“Award” means any stock option, stock appreciation right, stock award, stock unit, Performance Share, Performance Unit, and/or Other Stock-Based Award, whether granted under this Plan.

“Award Agreement” means the written document(s), including an electronic writing acceptable to the Administrator, and any notice, addendum or supplement thereto, memorializing the terms and conditions of an Award granted pursuant to the Plan and which shall incorporate the terms of the Plan.

“Board” means the Board of Directors of Liquidia Corporation.

“Cause” means, with respect to a Participant, except as otherwise provided in the relevant Award Agreement (i) the Participant’s plea of guilty or nolo contendere to, or conviction of, (A) a felony (or its equivalent in a non-United States jurisdiction) or (B) other conduct of a criminal nature that has or is likely to have a material adverse effect on the reputation or standing in the community of Liquidia Corporation, any of its Affiliates or a successor to Liquidia Corporation or an Affiliate, as determined by the Administrator in its sole discretion, or that legally prohibits the Participant from working for Liquidia Corporation, any of its Subsidiaries or a successor to Liquidia Corporation or a Subsidiary; (ii) a breach by the Participant of a regulatory rule that adversely affects the Participant’s ability to perform the Participant’s employment duties to Liquidia Corporation, any of its Subsidiaries or a successor to Liquidia Corporation or a Subsidiary, in any material respect; or (iii) the Participant’s failure, in any material respect, to (A) perform the Participant’s employment duties, (B) comply with the applicable policies of Liquidia Corporation, or of its Subsidiaries, or a successor to Liquidia Corporation or a Subsidiary, or (C) comply with covenants contained in any contract or Award Agreement to which the Participant is a party; provided, however, that the Participant shall be provided a written notice describing in reasonable detail the facts which are considered to give rise to a breach described in this clause and the Participant shall have 30 days following receipt of such written notice (the “Cure Period”) during which the Participant may remedy the condition and, if so remedied, no Cause for Termination of Service shall exist.

C-16

TABLE OF CONTENTS

“Change in Control” means the first of the following to occur: (i) a Change in Ownership of Liquidia Corporation, (ii) a Change in Effective Control of Liquidia Corporation, or (iii) a Change in the Ownership of Assets of Liquidia Corporation, as described herein and construed in accordance with Code section 409A.

(i) A “Change in Ownership of Liquidia Corporation” shall occur on the date that any one Person acquires, or Persons Acting as a Group acquire, ownership of the capital stock of Liquidia Corporation that, together with the stock held by such Person or Group, constitutes more than 50% of the total fair market value or total voting power of the capital stock of Liquidia Corporation. However, if any one Person is, or Persons Acting as a Group are, considered to own more than 50%, on a fully diluted basis, of the total fair market value or total voting power of the capital stock of Liquidia Corporation, the acquisition of additional stock by the same Person or Persons Acting as a Group is not considered to cause a Change in Ownership of Liquidia Corporation or to cause a Change in Effective Control of Liquidia Corporation (as described below). An increase in the percentage of capital stock owned by any one Person, or Persons Acting as a Group, as a result of a transaction in which Liquidia Corporation acquires its stock in exchange for property will be treated as an acquisition of stock.

(ii) A “Change in Effective Control of Liquidia Corporation” shall occur on the date either (A) a majority of members of Liquidia Corporation’ Board is replaced during any 12-month period by directors whose appointment or election is not endorsed by a majority of the members of Liquidia Corporation’ Board before the date of the appointment or election, or (B) any one Person, or Persons Acting as a Group, acquires (or has acquired during the 12-month period ending on the date of the most recent acquisition by such Person or Persons) ownership of stock of Liquidia Corporation possessing 50% or more of the total voting power of the stock of Liquidia Corporation.

(iii) A “Change in the Ownership of Assets of Liquidia Corporation” shall occur on the date that any one Person acquires, or Persons Acting as a Group acquire (or has or have acquired during the 12-month period ending on the date of the most recent acquisition by such Person or Persons), assets from Liquidia Corporation that have a total gross fair market value equal to or more than 50% of the total gross fair market value of all of the assets of Liquidia Corporation immediately before such acquisition or acquisitions. For this purpose, gross fair market value means the value of the assets of Liquidia Corporation, or the value of the assets being disposed of, determined without regard to any liabilities associated with such assets.

The following rules of construction apply in interpreting the definition of Change in Control:

(A) A “Person” means any individual, entity or group within the meaning of Section 13(d)(3) or 14(d)(2) of the Securities Exchange Act of 1934, as amended, other than employee benefit plans sponsored or maintained by Liquidia Corporation and by entities controlled by Liquidia Corporation or an underwriter, initial purchaser or placement agent temporarily holding the capital stock of Liquidia Corporation pursuant to a registered public offering.

(B) Persons will be considered to be Persons Acting as a Group (or Group) if they are owners of a corporation that enters into a merger, consolidation, purchase or acquisition of stock, or similar business transaction with the corporation. If a Person owns stock in both corporations that enter into a merger, consolidation, purchase or acquisition of stock, or similar transaction, such shareholder is considered to be acting as a Group with other shareholders only with respect to the ownership in that corporation before the transaction giving rise to the change and not with respect to the ownership interest in the other corporation. Persons will not be considered to be acting as a Group solely because they purchase assets of the same corporation at the same time or purchase or own stock of the same corporation at the same time, or as a result of the same public offering.

(C) A Change in Control shall not include a transfer to a related person as described in Code section 409A or a public offering of capital stock of Liquidia Corporation.

(D) For purposes of the definition of Change in Control, Section 318(a) of the Code applies to determine stock ownership. Stock underlying a vested option is considered owned by the individual who holds the vested option (and the stock underlying an unvested option is not considered owned by

C-17

TABLE OF CONTENTS

the individual who holds the unvested option). For purposes of the preceding sentence, however, if a vested option is exercisable for stock that is not substantially vested (as defined by Treasury Regulation §1.83-3(b) and (j)), the stock underlying the option is not treated as owned by the individual who holds the option.

“Code” means the Internal Revenue Code of 1986, as amended from time to time, and any successor thereto, the Treasury Regulations thereunder and other relevant interpretive guidance issued by the Internal Revenue Service or the Treasury Department. Reference to any specific section of the Code shall be deemed to include such regulations and guidance, as well as any successor section, regulations and guidance.

“Common Stock” means shares of common stock of Liquidia Corporation, par value $0.001 per share, and any capital securities into which they are converted.

“Company” means Liquidia Corporation and its Subsidiaries, except where the context otherwise requires. For purposes of determining whether a Change in Control has occurred, Company shall mean only Liquidia Corporation.

“Compensation Committee” means the Compensation Committee of the Board.

LIQUIDIA CORPORATION

RESTRICTED STOCK UNITS AGREEMENT
UNDER THE
LIQUIDIA CORPORATION
2020 LONG-TERM INCENTIVE PLAN

1. Terminology. Unless otherwise provided in this Agreement, capitalized terms used herein are defined in the Glossary at the end of this Agreement.

2. Vesting. All of the RSUs are nonvested and forfeitable as of the Grant Date. So long as your Service is continuous from the Grant Date through the applicable date upon which vesting is scheduled to occur, the RSUs will become vested and nonforfeitable in accordance with the vesting schedule set forth in the Notice. Except for the circumstances, if any, described in the Notice, none of the RSUs will become vested and nonforfeitable after your Service ceases.

3. Termination of Employment or Service. Unless otherwise provided in the Notice, if your Service with the Company ceases for any reason, all RSUs that are not then vested and nonforfeitable will be forfeited to the Company immediately and automatically upon such cessation without payment of any consideration therefor and you will have no further right, title or interest in or to such RSUs or the underlying shares of Common Stock.

4. Restrictions on Transfer. Neither this Agreement nor any of the RSUs may be assigned, transferred, pledged, hypothecated or disposed of in any way, whether by operation of law or otherwise, and the RSUs shall not be subject to execution, attachment or similar process. All rights with respect to this Agreement and the RSUs shall be exercisable during your lifetime only by you or your guardian or legal representative. Notwithstanding the foregoing, the RSUs may be transferred upon your death by last will and testament or under the laws of descent and distribution.

5. Settlement of RSUs.

(a) Manner of Settlement. You are not required to make any monetary payment (other than applicable tax withholding, if required) as a condition to settlement of the RSUs. The Company will issue to you, in settlement of your RSUs and subject to the provisions of Section 6 below, the number of whole shares of Common Stock that equals the number of whole RSUs that become vested, and such vested RSUs will terminate and cease to be outstanding upon such issuance of the shares. Upon issuance of such shares, the Company will determine the form of delivery (e.g., a stock certificate or electronic entry evidencing such shares) and may deliver such shares on your behalf electronically to the Company’s designated stock plan administrator or such other broker-dealer as the Company may choose at its sole discretion, within reason.

(b) Timing of Settlement. Your RSUs will be settled by the Company, via the issuance of Common Stock as described herein, on the date that the RSUs become vested and nonforfeitable. However, if a scheduled issuance date falls on a Saturday, Sunday or federal holiday, such issuance date shall instead fall on the next following day that the principal executive offices of the Company are open for business. In all cases, the issuance and delivery of shares under this Agreement is intended to comply with Treasury Regulation 1.409A-1(b)(4) and shall be construed and administered in such a manner.

6. Tax Withholding. On or before the time you receive a distribution of the shares subject to your RSUs, or at any time thereafter as requested by the Company, you hereby authorize any required withholding from the Common Stock issuable to you and/or otherwise agree to make adequate provision in cash for any sums required to satisfy the federal, state, local and foreign tax withholding obligations of the Company or any Affiliate which arise in connection with your RSUs (the “Withholding Taxes”). Additionally, the Company may, in its sole discretion, satisfy all or any portion of the Withholding Taxes obligation relating to your RSUs by any of the following means or by a combination of such means: (i) withholding from any compensation otherwise payable to you by the Company; (ii) causing you to tender a cash payment; (iii) permitting you to enter into a “same day sale” commitment with a broker-dealer that is a member of the Financial Industry Regulatory Authority (a “FINRA Dealer”) whereby you irrevocably elect to sell a

C-23

TABLE OF CONTENTS

portion of the shares to be delivered under the Agreement to satisfy the Withholding Taxes and whereby the FINRA Dealer irrevocably commits to forward the proceeds necessary to satisfy the Withholding Taxes directly to the Company; or (iv) withholding shares of Common Stock from the shares of Common Stock issued or otherwise issuable to you in connection with the RSUs with a Fair Market Value (measured as of the date shares of Common Stock are issued to you pursuant to Section 5) equal to the amount of such Withholding Taxes; provided, however, that the number of such shares of Common Stock so withheld shall not exceed the amount necessary to satisfy the Company’s required tax withholding obligations using the minimum statutory withholding rates for federal, state, local and foreign tax purposes, including payroll taxes, that are applicable to supplemental taxable income. Unless the tax withholding obligations of the Company and/or any Affiliate are satisfied, the Company shall have no obligation to deliver to you any Common Stock. In the event the Company’s obligation to withhold arises prior to the delivery to you of Common Stock or it is determined after the delivery of Common Stock to you that the amount of the Company’s withholding obligation was greater than the amount withheld by the Company, you agree to indemnify and hold the Company harmless from any failure by the Company to withhold the proper amount.

7. Adjustments for Corporate Transactions and Other Events.

(a) Stock Dividend, Stock Split and Reverse Stock Split. Upon a stock dividend of, or stock split or reverse stock split affecting, the Common Stock, the number of outstanding RSUs shall, without further action of the Administrator, be adjusted to reflect such event; provided, however, that any fractional RSUs resulting from any such adjustment shall be eliminated. Adjustments under this paragraph will be made by the Administrator, whose determination as to what adjustments, if any, will be made and the extent thereof will be final, binding and conclusive.

(b) Merger, Consolidation and Other Events. If the Company shall be the surviving or resulting corporation in any merger or consolidation and the Common Stock shall be converted into other securities, the RSUs shall pertain to and apply to the securities to which a holder of the number of shares of Common Stock subject to the RSUs would have been entitled. If the stockholders of the Company receive by reason of any distribution in total or partial liquidation or pursuant to any merger of the Company or acquisition of its assets, securities of another entity or other property (including cash), then the rights of the Company under this Agreement shall inure to the benefit of the Company’s successor, and this Agreement shall apply to the securities or other property (including cash) to which a holder of the number of shares of Common Stock subject to the RSUs would have been entitled, in the same manner and to the same extent as the RSUs.

8. Non-Guarantee of Employment or Service Relationship. Nothing in the Plan or this Agreement shall alter your at-will or other employment status or other service relationship with the Company, nor be construed as a contract of employment or service relationship between the Company and you, or as a contractual right of you to continue in the employ of, or in a service relationship with, the Company for any period of time, or as a limitation of the right of the Company to discharge you at any time with or without cause or notice and whether or not such discharge results in the forfeiture of any nonvested and forfeitable RSUs or any other adverse effect on your interests under the Plan.

9. Rights as Stockholder. You shall not have any of the rights of a stockholder with respect to any shares of Common Stock that may be issued in settlement of the RSUs until such shares of Common Stock have been issued to you.

10. The Company’s Rights. The existence of the RSUs shall not affect in any way the right or power of the Company or its stockholders to make or authorize any or all adjustments, recapitalizations, reorganizations, or other changes in the Company’s capital structure or its business, or any merger or consolidation of the Company, or any issue of bonds, debentures, preferred or other stocks with preference ahead of or convertible into, or otherwise affecting the Common Stock or the rights thereof, or the dissolution or liquidation of the Company, or any sale or transfer of all or any part of the Company’s assets or business, or any other corporate act or proceeding, whether of a similar character or otherwise.

11. Restrictions on Issuance of Shares. The issuance of shares of Common Stock upon settlement of the RSUs shall be subject to and in compliance with all applicable requirements of federal, state, or foreign law with respect to such securities. No shares of Common Stock may be issued hereunder if the issuance

C-24

TABLE OF CONTENTS

of such shares would constitute a violation of any applicable federal, state, or foreign securities laws or other law or regulations or the requirements of any stock exchange or market system upon which the Common Stock may then be listed. The inability of the Company to obtain from any regulatory body having jurisdiction the authority, if any, deemed by the Company’s legal counsel to be necessary to the lawful issuance of any shares subject to the RSUs shall relieve the Company of any liability in respect of the failure to issue such shares as to which such requisite authority shall not have been obtained. As a condition to the settlement of the RSUs, the Company may require you to satisfy any qualifications that may be necessary or appropriate, to evidence compliance with any applicable law or regulation, and to make any representation or warranty with respect thereto as may be requested by the Company.

12. Notices. All notices and other communications made or given pursuant to this Agreement shall be given in writing and shall be deemed effectively given upon receipt or, in the case of notices delivered by the Company to you, five (5) days after deposit in the United States mail, postage prepaid, addressed to you at the last address you provided to the Company, or in the case of notices delivered to the Company by you, addressed to the Administrator, care of the Company for the attention of its Secretary at its principal executive office or, in either case, if the receiving party consents in advance, transmitted and received via telecopy or via such other electronic transmission mechanism as may be available to the parties. Notwithstanding the foregoing, the Company may, in its sole discretion, decide to deliver any documents related to participation in the Plan and this award of RSUs by electronic means or to request your consent to participate in the Plan or accept this award of RSUs by electronic means. You hereby consent to receive such documents by electronic delivery and, if requested, to agree to participate in the Plan through an on-line or electronic system established and maintained by the Company or another third party designated by the Company.

13. Entire Agreement. This Agreement, together with the relevant Notice and the Plan, contain the entire agreement between the parties with respect to the RSUs granted hereunder. Any oral or written agreements, representations, warranties, written inducements, or other communications made prior to the execution of this Agreement with respect to the RSUs granted hereunder shall be void and ineffective for all purposes.

14. Amendment. This Agreement may be amended from time to time by the Administrator in its discretion; provided, however, that this Agreement may not be modified in a manner that would have a materially adverse effect on the RSUs as determined in the discretion of the Administrator, except as provided in the Plan or in a written document signed by each of the parties hereto.

15. 409A Savings Clause. This Agreement and the RSUs granted hereunder are intended to fit within the “short-term deferral” exemption from Section 409A of the Code as set forth in Treasury Regulation Section 1.409A-1(b) (4). In administering this Agreement, the Company shall interpret this Agreement in a manner consistent with such exemption. Notwithstanding the foregoing, if it is determined that the RSUs fail to satisfy the requirements of the short-term deferral rule and are otherwise deferred compensation subject to Section 409A, and if you are a “Specified Employee” (within the meaning set forth Section 409A(a)(2)(B)(i) of the Code) as of the date of your separation from service (within the meaning of Treasury Regulation Section 1.409A-1(h)), then the issuance of any shares that would otherwise be made upon the date of the separation from service or within the first six (6) months thereafter will not be made on the originally scheduled date(s) and will instead be issued in a lump sum on the date that is six (6) months and one day after the date of the separation from service, but if and only if such delay in the issuance of the shares is necessary to avoid the imposition of additional taxation on you in respect of the shares under Section 409A of the Code. Each installment of shares that vests is intended to constitute a “separate payment” for purposes of Section 409A of the Code and Treasury Regulation Section 1.409A-2(b)(2).

16. No Obligation to Minimize Taxes. The Company has no duty or obligation to minimize the tax consequences to you of this award of RSUs and shall not be liable to you for any adverse tax consequences to you arising in connection with this award. You are hereby advised to consult with your own personal tax, financial and/or legal advisors regarding the tax consequences of this award and by signing the Notice, you have agreed that you have done so or knowingly and voluntarily declined to do so.

C-25

You agree that before you may bring any legal action arising under, as a result of, pursuant to or relating to, this Agreement you will first exhaust your administrative remedies before the Administrator.

INCENTIVE STOCK OPTION AGREEMENT

UNDER THE

LIQUIDIA CORPORATION 2020 LONG-TERM INCENTIVE PLAN

1. Terminology. Capitalized terms used in this Agreement are defined in the correlating Stock Option Notice and/or the Glossary at the end of the Agreement.

2. Exercise of Options.

(a) Exercisability. The Options will become exercisable in accordance with the Exercisability Schedule set forth in the Stock Option Notice, so long as you are in the Service of the Company from the Grant Date through the applicable exercisability dates. None of the Options will become exercisable after your Service with the Company ceases, unless the Stock Option Notice provides otherwise with respect to exercisability that arises as a result of your cessation of Service.

(b) Right to Exercise. You may exercise the Options, to the extent exercisable, at any time on or before 5:00 P.M. Eastern Time on the Expiration Date or the earlier termination of the Options, unless otherwise provided under applicable law. Notwithstanding the foregoing, if at any time the Administrator determines that the delivery of Shares under the Plan or this Agreement is or may be unlawful under the laws of any applicable jurisdiction, or Federal, state or foreign securities laws, the right to exercise the Options or receive Shares pursuant to the Options shall be suspended until the Administrator determines that such delivery is lawful. If at any time the Administrator determines that the delivery of Shares under the Plan or this Agreement is or may violate the rules of the national securities exchange on which the shares are then listed for trade, the right to exercise the Options or receive Shares pursuant to the Options shall be suspended until the Administrator determines that such exercise or delivery would not violate such rules. Section 3 below describes certain limitations on exercise of the Options that apply in the event of your death, Total and Permanent Disability, or termination of Service. The Options may be exercised only in multiples of whole Shares and may not be exercised at any one time as to fewer than one hundred Shares (or such lesser number of Shares as to which the Options are then exercisable). No fractional Shares will be issued under the Options.

(c) Exercise Procedure. In order to exercise the Options, you must provide the following items to the Secretary of the Company or his or her delegate before the expiration or termination of the Options:

(i) notice, in such manner and form as the Administrator may require from time to time, specifying the number of Shares to be purchased under the Options; and

(ii) full payment of the Exercise Price for the Shares or properly executed, irrevocable instructions, in such manner and form as the Administrator may require from time to time, to effectuate a broker-assisted cashless exercise, each in accordance with Section 2(d) of this Agreement.

An exercise will not be effective until the Secretary of the Company or his or her delegate receives all of the foregoing items, and such exercise otherwise is permitted under and complies with all applicable federal, state and foreign securities laws. Notwithstanding the foregoing, if the Administrator permits payment by means of delivering properly executed, irrevocable instructions, in such manner and form as the Administrator may require from time to time, to effectuate a broker-assisted cashless exercise and such instructions provide for sale of Shares under a limit order rather than at the market, the exercise will not be effective until the earlier of the date the Company receives delivery of cash or cash equivalents in full payment of the Exercise Price or the date the Company receives confirmation from the broker that the sale instruction has been fulfilled, and the exercise will not be effective unless the earlier of such dates occurs on or before termination of the Options.

C-30

TABLE OF CONTENTS

(d) Method of Payment. You may pay the Exercise Price by:

(i) delivery of cash, certified or cashier’s check, money order or other cash equivalent acceptable to the Administrator in its discretion;

(ii) a broker-assisted cashless exercise in accordance with Regulation T of the Board of Governors of the Federal Reserve System through a brokerage firm designated or approved by the Administrator;

(iii) subject to such limits as the Administrator may impose from time to time, tender (via actual delivery or attestation) to the Company of other shares of Common Stock of the Company which have a Fair Market Value on the date of tender equal to the Exercise Price;

(iv) subject to such limits as the Administrator may impose from time to time, net share settlement with respect to any portions of the Options that do not qualify as incentive stock options within the meaning of Code section 422;

(v) any other method approved by the Administrator; or

(vi) any combination of the foregoing.

(e) Issuance of Shares upon Exercise. The Company shall issue to you the Shares underlying the Options you exercise as soon as practicable after the exercise date, subject to the Company’s receipt of the aggregate exercise price and the requisite withholding taxes, if any. Upon issuance of such Shares, the Company may deliver, subject to the provisions of Section 7 below, such Shares on your behalf electronically to the Company’s designated stock plan administrator or such other broker-dealer as the Company may choose at its sole discretion, within reason, or may retain such Shares in uncertificated book-entry form. Any share certificates delivered will, unless the Shares are registered or an exemption from registration is available under applicable federal and state law, bear a legend restricting transferability of such Shares.

3. Termination of Service.

(a) Termination of Unexercisable Options. If your Service with the Company ceases for any reason, the Options that are then unexercisable will terminate immediately upon such cessation.

(b) Exercise Period Following Termination of Service. If your Service with the Company ceases for any reason other than discharge for Cause, the Options that are then exercisable will terminate upon the earliest of:

(i) the expiration of 90 days following such cessation, if your Service ceases on account of (1) your termination by the Company other than a discharge for Cause, or (2) your voluntary termination other than for Total and Permanent Disability or death;

(ii) the expiration of 12 months following such cessation, if your Service ceases on account of your Total and Permanent Disability or death;

(iii) the expiration of 12 months following your death, if your death occurs during the periods described in clauses (i) or (ii) of this Section 3(b), as applicable; or

(iv) the Expiration Date.

In the event of your death, the exercisable Options may be exercised by your executor, personal representative, or the person(s) to whom the Options are transferred by will or the laws of descent and distribution.

(c) Misconduct. The Options will terminate in their entirety, regardless of whether the Options are then exercisable, immediately upon your discharge from Service for Cause, or upon your commission of any of the following acts during the exercise period following your termination of Service: (i) fraud on or misappropriation of any funds or property of the Company, or (ii) your breach of any provision of any employment, non-disclosure, non-competition, non-solicitation, assignment of inventions, or

C-31

TABLE OF CONTENTS

other similar agreement executed by you for the benefit of the Company, as determined by the Administrator, which determination will be conclusive.

(d) Changes in Status. If you cease to be a “common law employee” of the Company but you continue to provide bona fide services to the Company following such cessation in a different capacity, including without limitation as a director, consultant or independent contractor, then a termination of Service shall not be deemed to have occurred for purposes of this Section 3 upon such change in capacity. Notwithstanding the foregoing, the Options shall not be treated as incentive stock options within the meaning of Code section 422 with respect to any exercise that occurs more than three months after such cessation of the common law employee relationship (except as otherwise permitted under Code section 421 or 422). In the event that your Service is with a business, trade or entity that, after the Grant Date, ceases for any reason to be part or an Affiliate of the Company, your Service will be deemed to have terminated for purposes of this Section 3 upon such cessation if your Service does not continue uninterrupted immediately thereafter with the Company or an Affiliate of the Company.

4. Nontransferability of Options. These Options are nontransferable otherwise than by will or the laws of descent and distribution and during your lifetime, the Options may be exercised only by you or, during the period you are under a legal disability, by your guardian or legal representative. Except as provided above, the Options may not be assigned, transferred, pledged, hypothecated or disposed of in any way (whether by operation of law or otherwise) and shall not be subject to execution, attachment or similar process.

5. Qualified Nature of the Options.

(a) General Status. The Options are intended to qualify as incentive stock options within the meaning of Code section 422 (“Incentive Stock Options”), to the fullest extent permitted by Code section 422, and this Agreement shall be so construed. The Company, however, does not warrant any particular tax consequences of the Options. Code section 422 provides limitations, not set forth in this Agreement, respecting the treatment of the Options as Incentive Stock Options. You should consult with your personal tax advisors in this regard.

(b) Code Section 422(d) Limitation. Pursuant to Code section 422(d), the aggregate fair market value (determined as of the Grant Date) of shares of Common Stock with respect to which all Incentive Stock Options first become exercisable by you in any calendar year under the Plan or any other plan of the Company (and its parent and subsidiary corporations, within the meaning of Code section 424(e) and (f), as may exist from time to time) may not exceed $100,000 or such other amount as may be permitted from time to time under Code section 422. To the extent that such aggregate fair market value exceeds $100,000 or other applicable amount in any calendar year, such stock options will be treated as nonstatutory stock options with respect to the amount of aggregate fair market value thereof that exceeds the Code section 422(d) limit. For this purpose, the Incentive Stock Options will be taken into account in the order in which they were granted. In such case, the Company may designate the shares of Common Stock that are to be treated as stock acquired pursuant to the exercise of Incentive Stock Options and the shares of Common Stock that are to be treated as stock acquired pursuant to nonstatutory stock options by issuing separate certificates for such shares and identifying the certificates as such in the stock transfer records of the Company.

(c) Significant Stockholders. Notwithstanding anything in this Agreement or the Stock Option Notice to the contrary, if you own, directly or indirectly through attribution, stock possessing more than 10% of the total combined voting power of all classes of stock of the Company or of any of its subsidiaries (within the meaning of Code section 424(f)) on the Grant Date, then the Exercise Price is the greater of (a) the Exercise Price stated on the Stock Option Notice or (b) 110% of the Fair Market Value of the Common Stock on the Grant Date, and the Expiration Date is the last business day prior to the fifth anniversary of the Grant Date.

(d) Disqualifying Dispositions. If you make a disposition (as that term is defined in Code section 424(c)) of any Shares acquired pursuant to the Options within two years of the Grant Date or within one year after the Shares are transferred to you, you must notify the Company of such disposition in writing within 30 days of the disposition. The Administrator may, in its discretion, take reasonable

C-32

TABLE OF CONTENTS

steps to ensure notification of such dispositions, including but not limited to requiring that Shares acquired under the Options be held in an account with a Company-designated broker-dealer until they are sold.

6. Withholding of Taxes.

(a) At the time the Options are exercised, in whole or in part, or at any time thereafter as requested by the Company, you hereby authorize withholding from payroll or any other payment of any kind due to you and otherwise agree to make adequate provision for foreign, federal, state and local taxes required by law to be withheld, if any, which arise in connection with the Options (including upon a disqualifying disposition within the meaning of Code section 421(b)). The Company may require you to make a cash payment to cover any withholding tax obligation as a condition of exercise of the Options or issuance of share certificates representing Shares.

(b) The Administrator may, in its sole discretion, permit you to satisfy, in whole or in part, any withholding tax obligation which may arise in connection with the Options either by electing to have the Company withhold from the Shares to be issued upon exercise that number of Shares, or by electing to deliver to the Company already-owned shares, in either case having a Fair Market Value not in excess of the amount necessary to satisfy the statutory minimum withholding amount due.

7. Adjustments. The Administrator may make various adjustments to your Options, including adjustments to the number and type of securities subject to the Options and the Exercise Price, in accordance with the terms of the Plan. In the event of any transaction resulting in a Change in Control (as defined in the Plan) of the Company, the outstanding Options will terminate upon the effective time of such Change in Control unless provision is made in connection with the transaction for the continuation or assumption of such Options by, or for the substitution of the equivalent awards of, the surviving or successor entity or a parent thereof. In the event of such termination, you will be permitted, immediately before the Change in Control, to exercise or convert all portions of such Options that are then exercisable or which become exercisable upon or prior to the effective time of the Change in Control.

8. Non-Guarantee of Employment or Service Relationship. Nothing in the Plan or this Agreement will alter your at-will or other employment status or other service relationship with the Company, nor be construed as a contract of employment or service relationship between you and the Company, or as a contractual right for you to continue in the employ of, or in a service relationship with, the Company for any period of time, or as a limitation of the right of the Company to discharge you at any time with or without Cause or notice and whether or not such discharge results in the failure of any of the Options to become exercisable or any other adverse effect on your interests under the Plan.

9. No Rights as a Stockholder. You shall not have any of the rights of a stockholder with respect to the Shares until such Shares have been issued to you upon the due exercise of the Options. No adjustment will be made for dividends or distributions or other rights for which the record date is prior to the date such Shares are issued.

10. The Company’s Rights. The existence of the Options shall not affect in any way the right or power of the Company or its stockholders to make or authorize any or all adjustments, recapitalizations, reorganizations or other changes in the Company’s capital structure or its business, or any merger or consolidation of the Company, or any issue of bonds, debentures, preferred or other stocks with preference ahead of or convertible into, or otherwise affecting the Common Stock or the rights thereof, or the dissolution or liquidation of the Company, or any sale or transfer of all or any part of the Company’s assets or business, or any other corporate act or proceeding, whether of a similar character or otherwise.

11. Entire Agreement. This Agreement, together with the correlating Stock Option Notice and the Plan, contain the entire agreement between you and the Company with respect to the Options. Any oral or written agreements, representations, warranties, written inducements, or other communications made prior to the execution of this Agreement with respect to the Options shall be void and ineffective for all purposes.

C-33

TABLE OF CONTENTS

12. Amendment. This Agreement may be amended from time to time by the Administrator in its discretion; provided, however, that this Agreement may not be modified in a manner that would have a materially adverse effect on the Options or Shares as determined in the discretion of the Administrator, except as provided in the Plan or in a written document signed by you and the Company.

13. Conformity with Plan. This Agreement is intended to conform in all respects with, and is subject to all applicable provisions of, the Plan. Any conflict between the terms of this Agreement and the Plan shall be resolved in accordance with the terms of the Plan. In the event of any ambiguity in this Agreement or any matters as to which this Agreement is silent, the Plan shall govern. A copy of the Plan is available upon request to the Administrator.

14. Section 409A. This Agreement and the Options granted hereunder are intended to comply with, or otherwise be exempt from, Section 409A of the Code. This Agreement and the Options shall be administered, interpreted and construed in a manner consistent with this intent. Nothing in the Plan or this Agreement shall be construed as including any feature for the deferral of compensation other than the deferral of recognition of income until the exercise of the Options. Should any provision of the Plan or this Agreement be found not to comply with, or otherwise be exempt from, the provisions of Section 409A of the Code, it may be modified and given effect, in the sole discretion of the Administrator and without requiring your consent, in such manner as the Administrator determines to be necessary or appropriate to comply with, or to effectuate an exemption from, Section 409A of the Code. The foregoing, however, shall not be construed as a guarantee or warranty by the Company of any particular tax effect to you.

15. Electronic Delivery of Documents. By your signing the Notice, you (i) consent to the electronic delivery of this Agreement, all information with respect to the Plan and the Options, and any reports of the Company provided generally to the Company’s stockholders; (ii) acknowledge that you may receive from the Company a paper copy of any documents delivered electronically at no cost to you by contacting the Company by telephone or in writing; (iii) further acknowledge that you may revoke your consent to the electronic delivery of documents at any time by notifying the Company of such revoked consent by telephone, postal service or electronic mail; and (iv) further acknowledge that you understand that you are not required to consent to electronic delivery of documents.

16. No Future Entitlement. By execution of the Notice, you acknowledge and agree that: (i) the grant of these Options is a one-time benefit which does not create any contractual or other right to receive future grants of stock options, or compensation in lieu of stock options, even if stock options have been granted repeatedly in the past; (ii) all determinations with respect to any such future grants, including, but not limited to, the times when stock options shall be granted or shall become exercisable, the maximum number of shares subject to each stock option, and the purchase price, will be at the sole discretion of the Administrator; (iii) the value of these Options is an extraordinary item of compensation which is outside the scope of your employment contract, if any; (iv) the value of these Options is not part of normal or expected compensation or salary for any purpose, including, but not limited to, calculating any termination, severance, resignation, redundancy, end of service payments or similar payments, or bonuses, long-service awards, pension or retirement benefits; (v) the vesting of these Options ceases upon termination of employment with the Company or transfer of employment from the Company, or other cessation of eligibility for any reason, except as may otherwise be explicitly provided in this Agreement; (vi) if the underlying Common Stock does not increase in value, these Options will have no value, nor does the Company guarantee any future value; and (vii) no claim or entitlement to compensation or damages arises if these Options do not increase in value and you irrevocably release the Company from any such claim that does arise.
