NOTICE OF 2023 ANNUAL GENERAL MEETING OF SHAREHOLDERS
To Be Held on August 1, 2023, at 10:00 a.m. (Irish Standard Time)

To Our Shareholders:

You are cordially invited to attend the annual general meeting of shareholders (the “Meeting”) of Avadel Pharmaceuticals plc (the “Company”) to be held August 1, 2023, at 10:00 a.m. (Irish Standard Time) at the offices of Arthur Cox LLP, Ten Earlsfort Terrace, Dublin 2, D02 T380 Ireland, for the following purposes:

By separate resolutions, to elect the following six current Directors: Gregory J. Divis, Dr. Eric J. Ende, Geoffrey M. Glass, Dr. Mark A. McCamish, Linda S. Palczuk and Peter J. Thornton to the Board of Directors; each to serve a one-year term expiring at the conclusion of the next annual general meeting of shareholders (“Proposal 1”);

To ratify the appointment of Deloitte & Touche LLP as the Company’s independent registered public auditor and accounting firm for the fiscal year ending December 31, 2023, and to authorize, in a binding vote, the Audit Committee of the Board of Directors to set the independent registered public auditor and accounting firm remuneration (“Proposal 2”);

To approve the amendment to the Avadel Pharmaceuticals plc 2020 Omnibus Incentive Compensation Plan to increase the number of shares authorized for issuance under the plan by 6,500,000 shares (“Proposal 3”); and

To transact such other business as may properly be brought before the Meeting and any adjournments or postponements of the Meeting.

Proposals 1, 2 and 3 are ordinary resolutions, requiring a majority of the votes cast in person or by proxy at the Meeting.

During the Meeting, following a review of the Company’s affairs, the Company’s management will also present for consideration the Company’s Irish Statutory Financial Statements for the financial year ended December 31, 2022, along with the related directors’ and independent auditor’s reports. There is no requirement under Irish law that the Irish Statutory Financial Statements be approved by the shareholders, and no such approval will be sought at the Meeting.

This notice of the Meeting and accompanying proxy materials will first be made available to you on or about as a holder of record of the Company’s ordinary shares as of 5:00 p.m. (Irish Standard Time) on May 25, 2023. The Bank of New York Mellon, as the depositary (the “Depositary”), or a broker, bank or other nominee, will make these proxy materials available to holders of American Depositary Shares, each of which represents one ordinary share, nominal value US$0.01 per share, of the Company (“ADSs”).

If you hold ADSs, you may instruct the Depositary, either directly or through your broker, bank or other nominee, how to vote the ordinary shares represented by your ADSs. The Depositary has fixed a record date for the determination of holders of ADSs who shall be entitled to give such voting instructions. We have been informed by the Depositary that it has set the ADS record date for the Meeting as 5:00 p.m. (New York Time) on May 25, 2023. If you wish to have your votes cast at the meeting, you must follow the instructions in the enclosed voting instruction card from the Depositary, if you are a registered holder of ADSs, or in accordance with any instructions from your broker, bank or other nominee. Please note that only registered holders of ordinary shares, rather than ADSs, are entitled to attend, speak, and vote directly at the Meeting. Any shareholder entitled to attend, speak and vote at the Meeting may appoint one or more proxies, who need not be shareholder(s) of the Company.

If you hold ordinary shares as a shareholder of record (rather than a holder of ADSs) at 5:00 p.m. (Irish Standard Time) on May 25, 2023, the record date established by the Board of Directors, you will be eligible to

vote at the Meeting. You may vote (i) in person at the Meeting, (ii) by granting your voting proxy to the Company’s proxy designees (i.e., Gregory J. Divis, our Chief Executive Officer or Thomas S. McHugh, our Chief Financial Officer, each with full power of substitution) and by submitting such proxy by means of (A) the Internet, in the manner instructed on the applicable Notice of Internet Availability of Proxy Materials described below, (B) e-mail, in the manner instructed on the proxy card enclosed with paper copies of these proxy materials or (C) regular mail, using the return envelope enclosed with paper copies of these proxy materials to return the enclosed proxy card properly signed and dated or by delivering the proxy card (or proxy form set out in section 184 of the Companies Act (the “Companies Act”)) to the Company Secretary, Avadel Pharmaceuticals plc at Ten Earlsfort Terrace, Dublin 2, D02 T380 Ireland; or (iii) by granting your voting proxy to any person other than the Company’s proxy designees. If you submit a proxy to the Company’s proxy designees and do not provide specific voting instructions, you will be deemed to have instructed the Company’s proxy designees to vote your shares in accordance with the recommendations of the Board. If you wish to appoint as proxy any person other than the Company’s proxy designees, please contact the Company Secretary at our registered office; your nominated proxy must attend the Meeting in person in order for your votes to be cast. Registered holders of ordinary shares who vote by submitting their proxy card by mail (or by delivering it (or proxy form set out in section 184 of the Companies Act) to the Company Secretary, Avadel Pharmaceuticals plc at Ten Earlsfort Terrace, Dublin 2, D02 T380 Ireland), online or e-mail, or by granting their voting proxy directly to the Company’s proxy designees or to any other person, must ensure their proxy card is received at the address stated on the card, voted online or e-mailed to the address stated on the card by 10:00 a.m. (Irish Standard Time) on July 30, 2023.

Enclosed with this Proxy Statement are (i) a proxy card (for use by holders of our ordinary shares) or a voting instruction card (for use by holders of our ADSs), as applicable, and (ii) a copy of our Annual Report on Form 10-K for the fiscal year ended December 31, 2022. In addition, enclosed is a copy of the Company’s Irish Statutory Financial Statements for the financial year ended December 31, 2022, along with the related directors’ and independent auditor’s reports. Additional copies of these materials may be obtained without charge by writing to the Company Secretary of Avadel Pharmaceuticals plc at Ten Earlsfort Terrace, Dublin 2, D02 T380 Ireland, or downloaded from our website at www.Avadel.com.

We intend to use the Internet as the primary means of providing our proxy materials to shareholders and holders of our ADSs in connection with the Meeting. As a result, certain shareholders and holders of our ADSs may not receive paper copies of our proxy materials. We intend to mail shareholders and holders of our ADSs a Notice of Internet Availability of Proxy Materials with instructions for accessing the proxy materials and for voting via the Internet. The Notice of Internet Availability of Proxy Materials will also provide the date, time and location of the Meeting; the matters to be acted upon at the meeting and the Board of Directors’ recommendation with regard to each matter; a toll-free number, an e-mail address and a website where shareholders can request a paper or e-mail copy of our Proxy Statement, form of proxy card (for shareholders) and voting instruction card (for ADS holders), our Annual Report on Form 10-K for fiscal year 2022, and our Irish Statutory Financial Statements for the financial year ended December 31, 2022, along with the related directors’ and independent auditor’s reports; information on how to access the proxy card or voting instruction card, as applicable; and information on how to attend the Meeting and vote in person.

Your vote is very important. The Company encourages you to read the Proxy Statement and the accompanying materials and to vote your shares or ADSs, as applicable, as promptly as possible.

Please note that, if you are a holder of ordinary shares, rather than ADSs, in the absence of specific instructions as to how to vote, brokers may not vote your shares on the election of directors. You may revoke your proxy at any time before the vote is taken by delivering to the Company Secretary a written revocation, submitting a proxy with a later date (but to be received by 10:00 a.m. (Irish Standard Time) on July 30, 2023) or by voting your shares in person at the Meeting, in which case your prior proxy will be disregarded. Please note that voting in advance in any of the ways described will not prevent a holder of ordinary shares from attending the Meeting.

THE BOARD RECOMMENDS THAT YOU VOTE “FOR” PROPOSALS 1, 2 AND 3.

IMPORTANT NOTICE REGARDING THE AVAILABILITY OF PROXY MATERIALS FOR THE
ANNUAL GENERAL MEETING OF SHAREHOLDERS TO BE HELD ON AUGUST 1, 2023

We are mailing to holders of our ordinary shares and holders of our ADSs a Notice of Internet Availability of Proxy Materials (which we refer to as a “Notice”), rather than mailing a full paper set of the materials. The Notice contains instructions on how to access our proxy materials on the Internet, as well as instructions on obtaining a paper copy of the proxy materials. This process is more environmentally friendly and reduces our costs to print and distribute these materials. All holders of ADSs and holders of ordinary shares who do not receive such a Notice, including shareholders who have previously requested to receive a paper copy of the materials, will receive a full set of paper proxy materials by U.S. mail or other form of delivery if outside the United States.

Voting by the Internet is fast and convenient, and your vote is immediately confirmed and tabulated. If you receive a paper copy of the proxy materials, you may also vote by completing, signing, dating, and returning the accompanying proxy card, or the enclosed voting instruction card (in the case of ADSs, as applicable) in the enclosed return envelope furnished for that purpose. By using the Internet, you help us reduce postage and proxy tabulation costs. Please do not return the enclosed paper ballot if you are voting over the Internet.

As provided in the Notice, this Proxy Statement and our Annual Report on Form 10-K for the fiscal year ended December 31, 2022, will be available online at www.Avadel.com and on the website address designated on the Notice. The Company’s Irish Statutory Financial Statements for the financial year ended December 31, 2022, along with the related directors’ and independent auditor’s reports, will be available online at www.Avadel.com and on the website address designated on the Notice prior to the date of the Meeting.

General

This Proxy Statement and the accompanying materials are being furnished to you by the Board of Directors (the “Board”) of Avadel Pharmaceuticals plc (“Avadel,” the “Company,” “we,” “us,” “our” or similar terms) to solicit your proxy to vote your shares, or, as applicable, ADSs (as defined below) at our 2023 annual general meeting of shareholders (the “Meeting”), or at any adjournments or postponements thereof. The materials accompanying this Proxy Statement are (i) a proxy card (for use by holders of our ordinary shares) or a voting instruction card (for use by holders of American Depositary Shares), each of which represents one ordinary share, nominal value US$0.01 per share, of the Company (“ADSs”), as applicable, and (ii) a copy of our Annual Report on Form 10-K for the fiscal year ended December 31, 2022 (the “Annual Report”). In addition, we enclose together with this Proxy Statement, a copy of the Company’s Irish Statutory Financial Statements for the financial year ended December 31, 2022, along with the related directors’ and independent auditor’s reports.

The Board has designated the offices of Arthur Cox, located at Ten Earlsfort Terrace, Dublin 2, D02 T380 Ireland, as the place of the Meeting. The Meeting will be called to order at 10:00 a.m. (Irish Standard Time), August 1, 2023.

Voting and Board Recommendations

Shares. As of May 25, 2023, there were ordinary shares issued and outstanding, of which were represented by ADSs. All registered holders of ordinary shares at 5:00 p.m. (Irish Standard Time) on May 25, 2023, the record date established by the Board (the “Record Date”), may vote at the Meeting. Each ordinary share owned as of the Record Date is entitled to one vote on each matter properly presented at the Meeting. A holder of ADSs registered in such holder’s name on the books of The Bank of New York Mellon, which acts as the depositary under our ADS program (the “Depositary”) (a “registered holder of ADSs”), may instruct the Depositary to vote the ordinary shares represented by such ADSs, provided that the Depositary receives the holder’s voting instructions by noon (New York Time) on July 25, 2023, which is the date established by the Depositary for such purpose. A holder of ADSs held through a broker or other securities intermediary (a “beneficial holder of ADSs”) should follow the instructions that its broker or other securities intermediary provides to vote the ordinary shares underlying its ADSs. The Depositary has fixed a record date for the determination of holders of ADSs who shall be entitled to give such voting instructions. The Company has been informed by the Depositary that it has set the ADS record date for the Meeting as the close of business (New York Time) on May 25, 2023 (the “ADS Record Date”).

Attendance. Registered shareholders may attend the Meeting in person or by appointing a proxy. Holders of ADSs may not attend the Meeting in person or by proxy, unless they surrender their ADSs and become registered on the registry maintained on behalf of the Company before the Record Date. The process for surrendering your ADSs is coordinated through your broker, or, if you do not hold your ADSs through a broker, directly with the Depositary. The Company cannot accurately predict the number of days it will take to complete the process of becoming a registered shareholder.

Voting. Registered holders may vote (i) in person at the Meeting, (ii) by granting your voting proxy to the Company’s proxy designees (i.e., Gregory J. Divis, our Chief Executive Officer or Thomas S. McHugh, our Chief Financial Officer, each with full power of substitution) and by submitting such proxy by means of (A) the Internet, in the manner instructed on the applicable Notice of Internet Availability of Proxy Materials described below, (B) e-mail, in the manner instructed on the proxy card enclosed with paper copies of these proxy materials to return the enclosed proxy card properly signed and dated or by delivering the proxy card (or proxy form set out in section 184 of the Companies Act) to the Company Secretary, Avadel Pharmaceuticals plc at Ten Earlsfort Terrace, Dublin 2, D02 T380 Ireland or (C) regular mail, using the return envelope enclosed with paper copies of these proxy materials; or (iii) by granting your voting proxy to any person other than the Company’s proxy designees. If you submit a proxy to the Company’s proxy designees and do not provide specific voting instructions, you will be deemed to have instructed the Company’s proxy designees to vote your shares in accordance with the recommendations of the Board. The Company intends to first mail or make available printed versions of this Proxy Statement and the accompanying materials to its shareholders and holders of its ADSs on or about June 23, 2023. Registered holders of ordinary shares who vote by submitting their proxy card by mail (or by delivering it (or proxy form set out in section 184 of the Companies Act) to the Company Secretary, Avadel Pharmaceuticals plc at Ten Earlsfort Terrace, Dublin 2, D02 T380 Ireland), online or e-mail, or by granting their voting proxy directly to the Company’s proxy designees or to any other person, must ensure their proxy card is received at the address stated on the card or e-mailed to the address stated on the card by 10:00 a.m. (Irish Standard Time) on July 30, 2023.

Holders of ADSs may only vote by instructing the Depositary how to vote the ordinary shares represented by their ADSs. Voting instructions may be given to the Depositary by following the instructions on the voting instructions form provided for ADS holders enclosed with paper copies of these proxy materials or on the applicable Notice of Internet Availability of Proxy Materials described below. The Depositary will endeavor to vote the underlying ordinary shares as so instructed (in the case of ADSs held through a broker or other securities intermediary, you must rely on the procedures of such intermediary to ensure that your voting instructions are properly communicated to the Depositary for this purpose). Voting instructions as to ADSs must be received by the Depositary by noon (New York Time) on the ADS Record Date in order for the Depositary to endeavor to give effect to such instructions at the Meeting.

For registered shareholders and those holders of ADSs who received a Notice of Internet Availability of Proxy Materials in the mail, please follow the instructions set forth in the notice in order to access your proxy card (for registered shareholders) or voting instruction card (for holders of ADSs). The Notice of Internet Availability of Proxy Materials also provides the date, time and location of the Meeting; the matters to be acted upon at the meeting and the Board of Directors’ recommendation with regard to each matter; a toll-free number, an e-mail address and a website where shareholders can request a paper or e-mail copy of our Proxy Statement, form of proxy card or voting instruction card, our Annual Report on Form 10-K for fiscal year 2022, and our Irish Statutory Financial Statements for the financial year ended December 31, 2022, along with the related directors’ and independent auditor’s reports; information on how to access the proxy card or voting instruction card; information on how to vote by Internet, mail or e-mail; and information on how to attend the meeting and vote in person. Brokers and other nominees who hold ADSs on behalf of beneficial owners may send their own similar notice. All registered shareholders and holders of ADSs as of the applicable record date will have the ability to access our proxy materials on the website referred to in the Notice of Internet Availability of Proxy Materials or request to receive a printed set of the proxy materials. Instructions on how to request a printed copy by mail or electronically may be found in the Notice of Internet Availability of Proxy Materials and on the website referred to in such Notice, including an option to request paper copies of future proxy materials. We will mail this Proxy Statement, together with the accompanying form of proxy card, voting instruction card and Notice of Annual General Meeting of Shareholders, to those shareholders and ADS holders entitled to vote at the Annual Meeting who have properly requested paper copies of such materials within three business days of request.

Under the Company’s Constitution, shareholders who are registered on the register maintained on behalf of the Company at 5:00 p.m. (Irish Standard Time) on the Record Date will be entitled to attend and vote at the Meeting. For holders of ADSs, the Depositary has established the ADS Record Date as the record date for determining the holders of ADSs who will be entitled to give voting instructions.

If you are a registered holder of ordinary shares and do not vote at the Meeting in person or by submitting your proxy card by mail, online or e-mail, or by granting your voting proxy directly to the Company’s proxy

TABLE OF CONTENTS

designees or to any other person, your ordinary shares will not be counted in respect of any matter on which votes are cast at the Meeting and will have no effect on the outcome of any such matter. If you are a registered holder of ordinary shares and you grant your proxy directly to the Company’s proxy designees but do not provide specific voting instructions, such ordinary shares will be voted in accordance with the recommendations of the Board. If you are a registered holder and appoint a proxy to vote your shares, whether you submit your proxy by mail, online or e-mail, and you abstain from voting as to any matter, your ordinary shares will be treated as abstentions on such matters and will have no effect on the outcome of any such matter. For such purposes, your ordinary shares will be treated as abstentions with respect to any matter if (A) you appoint the Company’s proxy designees as your proxy and you expressly abstain with respect to such matter, or (B) you appoint a person other than the Company’s proxy designees to act as your proxy, you fail to give such person instructions as to such matter and such person uses his or her discretion as your proxy to abstain from voting as to such matter.

If you are a registered holder of ADSs and do not provide the Depositary with voting instructions as to how you would like the ordinary shares represented by your ADS to be voted, pursuant to the terms of the deposit agreement, the Depositary may deem such ADS holder to have instructed the Depositary to give, and in such case the Depositary shall give, a discretionary proxy to a person designated by the Company to vote such ordinary shares; thus, such ordinary shares will be voted in accordance with the recommendations of the Board.

If you are a beneficial holder of ADSs and do not provide voting instructions to your broker or other securities intermediary as to how you would like the ordinary shares represented by your ADSs to be voted, the broker or other securities intermediary will not have discretionary authority to provide voting instructions to the Depositary on any matter. As a result, pursuant to the terms of the deposit agreement, the Depositary may deem such ADS holder to have instructed the Depositary to give, and in such case the Depositary shall give, a discretionary proxy to a person designated by the Company to vote such ordinary shares; thus, such ordinary shares will be voted in accordance with the recommendations of the Board.

If you hold ADSs, whether as a registered holder or beneficially through a broker or other securities intermediary, and you provide instructions with respect to some but not all matters, the ordinary shares represented by your ADSs will not be voted with respect to the matters as to which you did not provide voting instructions, unless you are deemed to have given instructions under the deposit agreement terms described above.

However, if you do not give the Depositary any voting instructions, the Depositary will not cast any vote with respect to any matter as to which the Company informs the Depositary (and we have agreed with the Depositary to provide such information to the Depositary as promptly as practicable in writing) that (A) the Company does not wish such vote cast, (B) substantial opposition exists or (C) such matter materially and adversely affects the rights of holders of our ordinary shares or ADSs. We may give a similar notification with respect to additional resolutions. Thus, any shares underlying ADSs for which a voting instruction card is not timely received may be voted as to all matters on the agenda in the manner recommended by the Board herein, except to the extent we may otherwise notify the Depositary in writing for the reasons described above.

Unless otherwise stated or the context otherwise requires, references herein to shares include the shares represented by ADSs and references to our shareholders include the holders of ADSs.

With respect to any other matters that may properly come before the Meeting, including consideration of a motion to adjourn the Meeting to another time or place (including for the purpose of soliciting additional proxies), if proxies are returned, such proxies will be voted in a manner deemed by the proxy representatives named therein in their discretion to be in our best interests and the best interests of our shareholders. ADS voting instructions would extend only to the specific questions on the agenda, so shares represented by ADSs would not be voted as to any other matter that might properly come before the Meeting.

Quorum and Vote Required under Irish Law

In accordance with the Company’s Constitution, the presence, in person or by proxy, of five or more persons holding or representing by proxy at least a majority of the voting power of the Company constitutes a quorum for the conduct of business. No business may take place at a general meeting if a quorum is not

TABLE OF CONTENTS

present in person or by proxy. Our Board has no authority to waive quorum requirements stipulated in our memorandum and articles of association (the “Company’s Constitution”). Abstentions and broker non-votes will be counted as present for the purposes of establishing a quorum in respect of the proposals at the Meeting.

Your shares are counted as present at the Meeting if you attend the Meeting in person or if you properly return a proxy by mail, online or e-mail, or (in the case of ADS holders) you properly cause voting instructions to be delivered to the Depositary or you are deemed to have given instructions under the deposit agreement terms described above. Abstentions and broker non-votes will be counted for the purposes of establishing a quorum in respect of the proposals at the Meeting.

Proposals 1, 2 and 3 are ordinary resolutions, requiring a majority of the votes cast in person or by proxy at the meeting. Abstentions and broker non-votes will neither count for nor against such proposals.

Shareholder Communications to Directors

Shareholders may communicate directly with the Company’s Directors by writing to Geoffrey M. Glass, who is Chair of our Board, at the Company’s registered office at Ten Earlsfort Terrace, Dublin 2, D02 T380 Ireland. Mr. Glass will monitor these communications and provide appropriate summaries of all received messages to the Board at its regularly scheduled meetings. Where the nature of a communication warrants, Mr. Glass may decide to obtain the immediate attention of the appropriate committee of the Board, a non- management Director or the Company’s management or independent advisors. After reviewing shareholder messages, Mr. Glass and/or the Board will determine whether any response is necessary.

Expenses of Solicitation

All expenses of this solicitation, including the cost of preparing and mailing this Proxy Statement, will be borne by the Company. The Company may reimburse brokerage firms and other securities intermediaries representing beneficial owners of ADSs for their reasonable expenses in forwarding proxy materials to, and in soliciting voting instructions from such beneficial owners. The Company’s Directors, officers and employees may also solicit votes in person or by telephone, letter, facsimile, electronic mail, or other means of communications. These Directors, officers and employees will not be additionally compensated, but they may be reimbursed for reasonable out-of-pocket expenses in connection with such solicitation.

Additional Information

Avadel files annual, quarterly and current reports, Proxy Statements and other information with the Securities and Exchange Commission (the “SEC”). Avadel’s SEC filings are available to the public at the SEC’s web site at http://www.sec.gov. You may request a copy of any of these filings, at no cost, by request directed to the Company Secretary at Ten Earlsfort Terrace, Dublin 2, D02 T380 Ireland.

QUESTIONS AND ANSWERS ABOUT THE ANNUAL GENERAL MEETING

The following questions and answers are intended to briefly address some commonly asked questions regarding the Meeting (as defined below). These questions and answers only highlight some of the information contained in this Proxy Statement. They may not contain all of the information that is important to you. You should read carefully this entire Proxy Statement.

Why am I receiving these materials?

Avadel is providing these materials to registered holders of our ordinary shares and holders of ADSs, in order to solicit your proxy to vote your ordinary shares or ADSs at the Meeting to be held at 10:00 a.m. (Irish Standard Time), August 1, 2023, and at any postponement(s) or adjournment(s) thereof. The Meeting will be held at the offices of Arthur Cox LLP, located Ten Earlsfort Terrace, Dublin 2, D02 T380 Ireland. We intend to mail printed versions of these materials to registered shareholders and holders of ADSs on or about June 23, 2023.

What is included in these materials?

These materials include this Proxy Statement, a proxy card (for the registered holders of ordinary shares, as explained hereafter), a voting instruction card (for the holders of ADSs, as explained hereafter), and our Annual Report on Form 10-K filed by the Company with the SEC on March 29, 2023. In addition, we will provide our shareholders and holders of our ADSs with a copy (together at the time the other proxy materials are furnished or shortly thereafter under separate cover) of the Company’s Irish Statutory Financial Statements for the financial year ended December 31, 2022, along with the related directors’ and independent auditor’s reports.

Why did I receive a “Notice of Internet Availability of Proxy Materials” but no other proxy materials?

Avadel is distributing its proxy materials via the Internet under the “Notice and Access” method allowed by the rules of the U.S. Securities and Exchange Commission (the “SEC”). This method expedites your receipt of proxy materials, is more environmentally friendly conserving natural resources and reduces Avadel’s distribution costs. On or about June 23, 2023, Avadel intends to mail, to registered holders of its ordinary shares and holders of its ADSs, a Notice of Internet Availability of Proxy Materials (“Notice of Internet Availability”) containing instructions on how to access and review the proxy materials and how to vote online. If you prefer to receive printed copies of the proxy materials in the mail, please follow the instructions in the Notice of Internet Availability to request those materials.

What items will be voted on at the Meeting?

The Company is aware of three items on which shareholders will be asked to vote at the Meeting. Please see the Notice of 2023 Annual General Meeting for a listing of all such items to be voted on at the Meeting.

Could other matters be decided at the Meeting?

At this time, we are unaware of any matters, other than as set forth above and the possible submission of additional shareholder resolutions, as described under “Other Matters” elsewhere in this Proxy Statement that may properly come before the Meeting.

To address the possibility of another matter being validly proposed and properly presented at the Meeting, ordinary shares of registered holders who grant their proxy to the Company’s proxy designees will be voted “AGAINST” such matters, and ordinary shares of registered holders who grant their proxy to any other person will be voted in the discretion of such person as to such matters.

Ordinary shares represented by ADSs will not be voted on any matter not disclosed in the Proxy Statement.

Who may vote at the Meeting?

As of May 25, 2023, there were ordinary shares issued and outstanding, of which were represented by ADSs. Registered holders of ordinary shares at 5:00 p.m. (Irish Standard Time) on the record

TABLE OF CONTENTS

date established by the Board of Directors (the “Record Date”), may vote at the Meeting. A holder of ADSs registered in such holder’s name on the books of The Bank of New York Mellon, which acts as the depositary under our ADS program (the “Depositary”) (a “registered holder of ADSs”) may instruct the Depositary to vote the ordinary shares represented by such ADSs, provided that the Depositary receives the holder’s voting instructions by noon (New York Time) on July 25, 2023, which is the date established by the Depositary for such purpose. A holder of ADSs held through a brokerage, bank or other account (a “beneficial holder of ADSs”) should follow the instructions that its broker, bank or other nominee provides to vote the ordinary shares underlying its ADSs. The Depositary has fixed a record date for the determination of holders of ADSs who shall be entitled to give such voting instructions. The Company has been informed by the Depositary that it has set the ADS record date for the Meeting as the close of business (New York Time) on May 25, 2023 (the “ADS Record Date”).

How does the Board of Directors recommend that I vote?

The Board of Directors recommends that you vote “FOR” each of proposals 1, 2 and 3.

If I hold ADSs instead of ordinary shares, are my rights to attend and vote at the Meeting different?

Yes. Attendance and voting rights are different depending on whether you hold ordinary shares or ADSs, as follows:

Attendance: Registered shareholders of ordinary shares may attend the Meeting in person or by appointing a proxy. You may not attend the Meeting in person or by proxy if you hold only ADSs. However, you may attend and vote at the Meeting if you surrender your ADSs and become registered on the register maintained on behalf of the Company by 5:00 p.m. (Irish Standard Time) on May 25, 2023. The process for surrendering your ADSs is coordinated through your broker, or, if you do not hold your ADSs through a broker, directly with the Depositary. The Company cannot accurately predict the number of days it will take to complete the process of becoming a registered shareholder.

Voting: Registered holders may vote (i) in person at the Meeting, (ii) by granting your voting proxy to the Company’s proxy designees (i.e., Gregory J. Divis, our Chief Executive Officer or Thomas S. McHugh, our Chief Financial Officer, each with full power of substitution) pursuant to the instructions included on the proxy card, which include submitting such proxy by means of (A) the Internet, in the manner instructed on the applicable Notice of Internet Availability of Proxy Materials described below, (B) e-mail, in the manner instructed on the proxy card enclosed with paper copies of these proxy materials or (C) regular mail, using the return envelope enclosed with paper copies of these proxy materials to return the enclosed proxy card properly signed and dated or by delivering the proxy card (or proxy form set out in section 184 of the Companies Act (the “Companies Act”)) to the Company Secretary, Avadel Pharmaceuticals plc at Ten Earlsfort Terrace, Dublin 2, D02 T380 Ireland; or (iii) by granting your voting proxy to any person other than the Company’s proxy designees. If you submit a proxy to the Company’s proxy designees and do not provide specific voting instructions, you will be deemed to instruct the Company’s proxy designees to vote your shares in accordance with the recommendations of the Board. Registered holders of ordinary shares who vote by submitting their proxy card by mail, online or e-mail, or by granting their voting proxy directly to the Company’s proxy designees or to any other person, must ensure their proxy card is received at the address stated on the card or e-mailed to the address stated on the card no later than 48 hours prior to the appointed time of the Meeting in accordance with Irish law, such deadline being 10:00 a.m. (Irish Standard Time) on July 30, 2023.

Holders of ADSs may only vote by instructing the Depositary how to vote the ordinary shares represented by their ADSs. Voting instructions may be given to the Depositary by following the instructions on the voting instructions form provided for ADS holders to their broker or other securities intermediary, or, if they do not hold their ADSs through such an intermediary, directly to the Depositary; and the Depositary will endeavor to vote the underlying ordinary shares as so instructed (in the case of ADSs held through a broker or other securities intermediary, you must rely on the procedures of such intermediary to ensure that your voting instructions are properly communicated to the Depositary for this purpose). The Depositary has established noon (New York Time) on July 25, 2023, as the date by which voting instructions as to ADSs must be received by the Depositary in order for the Depositary to endeavor to give effect to such instructions at the Meeting.

TABLE OF CONTENTS

For holders of ADSs, the Depositary has established the ADS Record Date as the record date for determining the holders of ADSs who will be entitled to give voting instructions.

If I am a registered holder of ordinary shares, how will my ordinary shares be voted if I do not vote or if I grant a proxy?

If you are a registered holder of ordinary shares and do not vote at the Meeting in person, via the Internet, by submitting your voting instructions by returning your proxy card by mail addressed to the Company as indicated on the proxy card or voting instruction card, by e-mail to the Company at general.meeting@avadel.com or by granting your voting proxy directly to any person, your ordinary shares will not be counted in respect of any matter on which votes are cast at the Meeting and will have no effect on the outcome of any such matter.

If you are a registered holder of ordinary shares and you grant your proxy to any individual, your shares will be voted as you instruct by the individuals named on the applicable proxy, or, if you fail to provide instructions to such person as to any matter, at the discretion of such person with respect to such matter.

If you are a registered holder of ordinary shares and you submit a proxy to the Company’s proxy designees and do not provide specific voting instructions, you will be deemed to have instructed the Company’s proxy designees to vote your shares in accordance with the recommendations of the Board.

How will the ordinary shares represented by my ADSs be voted if I do not provide voting instructions to the Depositary or my broker or other securities intermediary?

If you are a registered holder of ADSs and do not provide the Depositary with voting instructions as to how you would like the ordinary shares represented by your ADS to be voted or you do not return your voting instruction form, pursuant to the terms of the deposit agreement, the Depositary may deem you to have instructed the Depositary to give, and in such case the Depositary shall give, a discretionary proxy to a person designated by the Company to vote such ordinary shares; thus, such ordinary shares will be voted in accordance with the recommendations of the Board.

If you are a beneficial holder of ADSs and do not provide voting instructions to your broker or other securities intermediary as to how you would like the ordinary shares represented by your ADSs to be voted or do not return your voting instruction form, the intermediary will not have discretionary authority to provide voting instructions to the Depositary on any matter. As a result, pursuant to the terms of the deposit agreement, the Depositary may deem you to have instructed the Depositary to give, and in such case the Depositary shall give, a discretionary proxy to a person designated by the Company to vote such ordinary shares; thus, such ordinary shares will be voted in accordance with the recommendations of the Board.

However, if you do not give the Depositary any voting instructions, the proxy appointed by the Depositary will not cast any vote with respect to any matter as to which the Company informs the Depositary (and we have agreed with the Depositary to provide such information to the Depositary as promptly as practicable in writing) that (x) the Company does not wish such vote cast, (y) substantial opposition exists or (z) such matter materially and adversely affects the rights of holders of our ordinary shares or ADSs. Thus, any shares underlying ADSs for which a voting instruction card is not timely received may be voted as to all matters on the agenda in the manner recommended by the Board herein, except to the extent we may otherwise inform the Depositary in writing for the reasons described above.

If you hold ADSs, whether as a registered holder or beneficially through a broker or other securities intermediary, and you provide instructions with respect to some but not all matters, the ordinary shares represented by your ADSs will not be voted with respect to the matters as to which you did not provide voting instructions, unless you are deemed to have given an instruction under the deposit agreement provisions described above.

TABLE OF CONTENTS

instructions would extend only to the specific questions on the agenda, so shares represented by ADSs would not be voted as to any other matter that might come before the Meeting.

May shareholders ask questions?

Yes. Representatives of the Company will answer shareholders’ questions of general interest following the Meeting. In order to give a greater number of shareholders an opportunity to ask questions, individuals or groups will be allowed to ask only one question, and no repetitive or follow-up questions will be permitted.

Can I change my mind after I vote?

Receipt by the Company of your proxy card by mail or e-mail or appointing a proxy in advance of the Meeting will not preclude you from attending and voting at the Meeting. If you are a registered holder of ordinary shares and submit your proxy card to vote by mail, by e-mail or by appointing a proxy in advance of the meeting, you may change or revoke your proxy before it is exercised by attending and voting at the Meeting. If you hold ADSs directly or through a broker, bank or other nominee, you must follow the voting instructions provided by the Depositary or such broker, bank or other nominee if you wish to change your vote. The last instructions you submit prior to the deadline indicated by the Depositary or the broker, bank or other nominee, as applicable, will be used to instruct the Depositary how to vote the ordinary shares represented by your ADSs.

Who will count the votes?

Representatives of the Depositary will tabulate the voting instruction cards of ADS holders, and the Company will count the votes received from ordinary shareholders voting by way of proxy cards and/or by attending and voting at the Meeting.

Is my vote confidential?

Proxy instructions, ballots and voting tabulations that identify individual shareholders are handled in a manner that protects your voting privacy. Your vote will not be disclosed either within the Company or to third parties, except:

•

As necessary to meet applicable legal requirements;

•

To allow for the tabulation and certificate of votes; and

•

To facilitate a successful proxy solicitation.

Occasionally, shareholders provide written suggestions, comments or questions on their proxy cards, which may be forwarded to the Company’s management and the Board.

What does it mean if I receive more than one proxy card?

It means you hold ADSs in multiple accounts with brokers or other securities intermediaries. Please vote all of these ADSs. We recommend you contact your broker or other securities intermediary and/or the Depositary to consolidate as many accounts as possible under the same name and address. The Depositary may be reached at 1-888-BNY-ADRS (1-888-269-2377).

How many votes must be present to hold the Meeting?

Five or more persons holding or representing by proxy at least a majority of the voting power of the Company must be present for the meeting to be valid and to act on ordinary resolutions. If a quorum is not present when we convene the Meeting, the Board will give a second notice of the Meeting.

What will happen if a quorum is not present at the Meeting?

If the required quorum is not present when we convene the Meeting on August 1, 2023, we intend to adjourn and reconvene the Meeting.

TABLE OF CONTENTS

Your shares are counted as present at the Meeting if you attend the Meeting in person or if you properly return a proxy by mail or e-mail. Abstentions will be counted for purposes of establishing a quorum at the Meeting, but shares that are not voted will not be counted for such purposes.

How will a broker “non-vote” affect the vote?

A broker non-vote happens when a bank, broker or other securities intermediary who holds an ADS does not receive voting instructions from the beneficial owners of such ADS and does not have discretionary voting power with respect to a resolution to be voted upon at the Meeting. In such a case, the bank, broker or other securities intermediary is not permitted to instruct the Depositary how to vote with respect to such resolution, and the Depositary may vote the ordinary shares underlying such ADS in the manner recommended by the Board. As a result, ADSs that are the subject of a broker non-vote are included for quorum purposes, and a broker non-vote with respect to a resolution may be counted as a vote cast on such resolution.

When will the Company announce the voting results?

The Company will announce voting results of the Meeting on a Current Report on Form 8-K filed within four business days of the Meeting.

What if other matters are presented for consideration at the Meeting?

As of the date of this Proxy Statement, we know of no matters that will be presented for consideration at the Meeting other than those matters discussed in this Proxy Statement. If any other matters properly come before the Meeting and call for a vote of shareholders, validly executed proxies in the enclosed forms of proxy and voting instruction cards returned to Avadel will be voted in accordance with the recommendation of the Board, in the absence of such a recommendation, in accordance with the judgment of the proxy holders.

Whom should I contact if I have additional questions concerning the Proxy Statement, proxy card or voting instruction card?

If you have any questions concerning the information contained in this Proxy Statement or require assistance completing the proxy card or voting card, you may contact Jerad G. Seurer, General Counsel and Company Secretary at +1 636-730-1420.

TABLE OF CONTENTS

CORPORATE GOVERNANCE

General

Our business and affairs are managed under the direction of the Board in accordance with Irish law and the provisions of our Constitution (which comprises our memorandum and articles of association). Members of the Board are kept informed of our business through discussions with the Chair and Chief Executive Officer and other officers, by reviewing materials provided to them and by participating in meetings of the Board and its committees. The corporate governance practices we follow are summarized below.

Board Leadership Structure

Traditionally, our Board has had a general policy that the positions of the Chair and Chief Executive Officer should be held by separate persons. However, this general policy serves as part of a flexible framework within which the Board may conduct its business and is not a binding legal obligation. Our Board believes it should have the flexibility to make its determination as to whether these positions should be held by separate persons or one person at any given point in time in the way it believes best to provide appropriate leadership for us at that time. Presently, our Chair position is a non-executive position held by an independent director. The current Chair is Geoffrey M. Glass. Our Chair’s primary responsibilities are to preside at meetings of the Board and of the non-management and independent Board members, serve as the principal liaison between our Chief Executive Officer and management, on the one hand, and the Board, on the other hand, and provide not only our other directors, but also our shareholders, with an independent leadership contact. The Board recognizes there could be circumstances in the future that would lead it to combine the positions of Chair of the Board and Chief Executive Officer.

Role in Risk Oversight

Our Board’s role in risk management is primarily one of oversight with the day-to-day responsibility for risk management implemented by our management team. At regularly scheduled meetings, the Board receives management updates on our business operations, financial results and strategy and discusses risks related to the business. In carrying out its risk oversight function, our Board has three standing committees: Audit, Compensation and Nominating and Corporate Governance, each of which is responsible for risk oversight within that committee’s area of responsibility.

As part of its responsibilities, the Audit Committee oversees our financial policies, including financial risk management. The Audit Committee assists our Board in its oversight of risk management by discussing with management, particularly the Chief Financial Officer, our guidelines and policies regarding financial and enterprise risk management and risk appetite, including major risk exposures and the steps management has taken to monitor and control risk exposures. The Audit Committee also annually receives and considers a report from Deloitte & Touche LLP regarding the Company’s internal controls over financial reporting.

Each of the other committees of our Board considers risks within its areas of responsibility. The Compensation Committee oversees risk management as it relates to our compensation plans, policies and practices in connection with structuring our executive compensation programs and reviewing our incentive compensation programs for other employees and has reviewed with management whether our compensation programs may create incentives for our employees to take excessive or inappropriate risks that could have a materially adverse effect on the Company. Our Compensation Committee has concluded that none of the Company’s compensation programs are reasonably likely to cause management to take inappropriate or excessive risks. The Nominating and Corporate Governance Committee considers risks relating to board membership and corporate governance.

Diversity

The Nominating and Corporate Governance Committee considers diversity, along with other factors such as character, integrity, judgment, independence, skills, education, expertise, business acumen, business experience, length of service, understanding of the Company’s business and industry, conflicts of interest, and other commitments when selecting new Board members. We are committed to identifying, recruiting and advancing candidates offering such diversity in future searches.

TABLE OF CONTENTS

We consider, in identifying first-time candidates, nominees for director, or evaluating individuals recommended by shareholders, the current composition of the Board in light of the diverse communities and geographies we serve and the interplay of the candidate’s or nominee’s diverse individual experience, education, skills, background and other qualities and attributes with those of the other Board members. The Nominating and Corporate Governance Committee and the Board monitor the Board’s effectiveness through the Board’s self-evaluation process. The Nominating and Corporate Governance Committee and the Board believe the current composition of the Board reflects a group of highly talented individuals with diverse backgrounds, skills, professional and industry experience, and other personal qualities and attributes best suited to perform oversight responsibilities for the Company and its shareholders.

While our Board and Nominating and Corporate Governance Committee do not specify assigned weights to particular criteria, our Board and Nominating and Corporate Governance Committee believe it is essential that members of our Board represent diverse viewpoints and that the backgrounds and qualifications of our directors, considered as a group, should provide a composite mix of experience, knowledge and abilities that will allow our Board to promote our strategic objectives and fulfill its responsibilities to our shareholders. In particular, diversity in terms of race, ethnicity, age, and gender is viewed as important, in addition to many other factors, including industry knowledge, operational experience, scientific and academic expertise and personal backgrounds. Under the proposed Nasdaq listing rule, currently subject to review and approval by the SEC, directors who self-identify as (i) female, (ii) an underrepresented minority, or (iii) LGBTQ+ are defined as being diverse.

Board Diversity Matrix

The composition of the Board currently includes six individuals who are diverse under the Nasdaq listing rule regarding board diversity. Under the Nasdaq listing rule, directors who self-identify as (i) female, (ii) an underrepresented minority or (iii) LGBTQ+ are defined as being diverse.

Nominees Standing for Election

The Nominating and Corporate Governance Committee has recommended, and the Board has nominated, the following individuals for director: Gregory J. Divis, Dr. Eric J. Ende, Geoffrey M. Glass, Dr. Mark A. McCamish, Linda S. Palczuk and Peter J. Thornton. All of the nominees are current members of our Board. Except for Mr. Divis, our Chief Executive Officer, all of the nominees for director have been determined to be independent under the rules of the Nasdaq Global Market. Our Nominating and Corporate Governance Committee has reviewed each nominee’s qualifications and has recommended to our Board that each nominee be submitted to a vote of our shareholders at the Meeting, each to serve until the 2024 annual meeting of shareholders or until his or her successor is duly elected and qualified. Each of our nominees has

consented to being named in this Proxy Statement and has agreed to serve if elected. If a nominee is unavailable to serve as a director, full discretion is reserved to the persons named as proxies to vote for another nominee proposed by the Nominating and Corporate Governance Committee and the Board, or the Board may reduce the number of directors to be elected at the Meeting. Proxies cannot be voted for a greater number of persons than the number of nominees named in the Proxy Statement. The following table provides summary information about each director nominee as of April 7, 2023. Each director is elected annually by a majority of the votes cast.

Corporate Governance Guidelines

The Board has adopted corporate governance guidelines that set forth the practices of the Board with respect to the qualification, selection and election of directors, director orientation and continuing education, director responsibilities, Board composition and performance, director access to management and independent advisors, director compensation guidelines, management evaluation and succession, policies regarding the independent directors, meetings of the non-management directors, the policy on communicating with the non-management directors and various other issues. A copy of our corporate governance guidelines is available at https://investors.avadel.com/corporate-governance/highlights. A printed copy is available free of charge to any shareholder who requests it by contacting the Company Secretary in writing at Ten Earlsfort Terrace, Dublin 2, D02 T380 Ireland.

Board Standards of Independence

The Board sets our independence standards in our corporate governance guidelines. The director independence standards provide that a majority of the Board must be independent under the independence standards established by the corporate governance guidelines, Nasdaq, and the SEC as in effect from time to time. For a Board member or candidate for election to the Board to qualify as independent, the Board must determine that the person and his or her immediate family members do not have a material relationship with us (either directly or as a partner, shareholder or officer of an organization that has a relationship with us) or any of our affiliates. Under the categorical standards adopted by the Board, a member of the Board is not independent if:

•

The director is, or has been within the last three years, our employee, or an immediate family member is, or has been within the last three years, an executive officer of the Company;

•

The director has received, or has an immediate family member who has received, during any twelve-month period within the last three years, more than $120,000 in direct compensation from us, other than director and committee fees and pension or other forms of deferred compensation for prior service (provided such compensation is not contingent in any way on continued service);

TABLE OF CONTENTS

•

(i) The director is a current partner or employee of a firm that is our internal or external auditor; (ii) the director has an immediate family member who is a current partner of such a firm; (iii) the director has an immediate family member who is a current employee of such a firm and personally works on our audit; or (iv) the director or an immediate family member was within the last three years a partner or employee of such a firm and personally worked on our audit within that time;

•

The director or an immediate family member is, or has been within the last three years, employed as an executive officer of another company where any of our present executive officers at the same time serves or served on that company’s compensation committee; or

•

The director is a current employee, or an immediate family member is a current executive officer, of a company that has made payments to, or received payments from, us for property or services in an amount which, in any of the last three fiscal years, exceeds the greater of $1 million, or two percent, of such other company’s consolidated gross revenues.

The Board will also consider a director’s charitable relationships. Contributions to tax-exempt organizations are not considered payments for purposes of the test in the final bullet point above, provided that we are required to disclose in our annual Proxy Statement any such contributions made by us to any tax-exempt organization in which any independent director serves as an executive officer if, within the preceding three years, contributions in any single fiscal year from us to the organization exceeded the greater of $1 million, or two percent, of such tax-exempt organization’s consolidated gross revenues.

For purposes of the above independence standards, an “immediate family member” includes a person’s spouse, parents, children, siblings, mothers- and fathers-in-law, sons- and daughters-in-law, brothers- and sisters-in-law and anyone (other than domestic employees) who shares such person’s home. When applying the look-back provisions set forth above, the Board need not consider individuals who are no longer immediate family members as a result of legal separation or divorce, or those who have died or become incapacitated.

The Board has affirmatively determined that each member of the Board (besides Gregory J. Divis, our Chief Executive Officer) standing for election to the Board is independent in accordance with the above standards. Additionally, we made no contributions during fiscal year 2022 to any charitable organization in which an independent director serves as an executive officer in any single fiscal year within the preceding three fiscal years in an amount in excess of the greater of $1 million, or two percent, of the charitable organization’s consolidated gross revenues.

Board Meetings and Attendance at Meeting of Shareholders

During fiscal year 2022, there were 13 meetings of the Board held either in-person or by teleconference. Each incumbent director attended at least seventy-five percent (75%) of the aggregate of: (1) the total number of meetings of the Board held during the period that the individual served; and (2) the total number of meetings held by all committees of the Board on which the director served during the period that such individual served. All directors are strongly encouraged to attend the annual general meeting of shareholders.

Board Practices

Non-executive directors of the Company receive fees for their services and may be awarded restricted shares and/or share options (as set forth in the Executive Compensation section below). Non-executive directors are reimbursed, upon request, for expenses incurred in attending Board meetings. Upon termination, no benefits are provided to non-executive directors.

All directors are elected by the shareholders at each annual general meeting of shareholders. A quorum of the Board consists of one-half of the members of the Board, and actions shall be approved by the vote of a majority of the Board members present or represented by other members of the Board. Subject to the Constitution, the Board has the ability to determine its own internal rules for certain procedures. The Chair of the Board does not have the ability to cast a deciding vote in the event of a tie vote. A director may give a proxy to another director, but a director cannot represent more than one other director at any particular meeting. Members of the Board represented by another member at meetings do not count for purposes of determining the existence of a quorum.

TABLE OF CONTENTS

Directors are required to comply with applicable Irish law and the Company’s Constitution. Irish law permits, and the Company’s Constitution includes provisions for, the indemnification of our officers and directors to the extent permissible under the Companies Act 2014 (the “Companies Act”). In addition, we continue to contract for liability insurance for the benefit of our officers and directors similar to the insurance we have previously obtained. We believe the indemnity provisions in the Company’s Constitution and the insurance policies are important to our ability to attract and retain qualified directors and executive officers.

Compensation Committee

Composition, Qualifications and Governance

The Board has a Compensation Committee composed of Linda S. Palczuk (Chair), Dr. Mark A. McCamish and Peter J. Thornton. The Board has determined that all of the members of the Compensation Committee are independent within the meaning of the listing standards of Nasdaq. The Compensation Committee makes recommendations to the Board on the compensation of the executive officers of the Company, including the Chief Executive Officer. The Board makes the final decisions on compensation. The Compensation Committee has a written charter, which is available at https://investors.avadel.com/corporate-governance/highlights. The Compensation Committee reviews the charter annually and works with the Board to amend it as appropriate to reflect the evolving role of the Compensation Committee.

The Compensation Committee met four times during 2022.

The Compensation Committee, on an annual basis, reviews and approves corporate goals and objectives relevant to Chief Executive Officer and executive officers compensation, evaluates the Chief Executive Officer’s and executive officer’s performance in light of those goals and objectives, and based on this evaluation recommends to the Board, for the Chief Executive Officer’s and executive officers, (a) the annual base compensation or salary amount, (b) annual bonus arrangements, if any, (c) any long-term incentive compensation, (d) any employment agreements, severance arrangements, and change in control and similar agreements/provisions, and any amendments, supplements or waivers to the foregoing agreements, in each case as, when and if deemed necessary or advisable and (e) any perquisites, special or supplemental benefits.

Compensation Committee Interlocks and Insider Participation

The directors who served as members of the Compensation Committee during 2022 were Dr. Mark A. McCamish, Linda S. Palczuk (Chair) and Peter J. Thornton, none of whom is currently, or ever has been, an officer or employee of our Company, or had any relationship that is required to be disclosed in this proxy statement as a transaction with a related party. During 2022, none of our executive officers served as a member of the board of directors or the compensation committee (or other board committee performing equivalent functions) of any entity that had one or more of its executive officers serving on our Compensation Committee or our Board.

Audit Committee

Composition, Qualifications and Governance

Where the nature of a communication warrants, Mr. Glass may decide to obtain the immediate attention of the appropriate committee of the Board, a non-management Director or the Company’s management or independent advisors. After reviewing shareholder messages, Mr. Glass and/or the Board will determine whether any response is necessary.

PROPOSAL 1
ELECTION OF DIRECTORS
(Ordinary Resolution)

ITEM 1 ON PROXY CARD

Background

Our Board currently consists of six directors, all of whom were elected at the 2022 annual general meeting of shareholders and five of whom are non-executive directors. Our directors hold office until the next annual general meeting of shareholders, or, if earlier, until their successors have been elected or until the earlier of their resignation or removal. The Board, upon unanimous recommendation of the Nominating and Governance Committee, unanimously approved each of the six persons named below as nominees for election to the Board at the Meeting. Each of the six nominees: (i) is currently a member of the Board, (ii) has been nominated for election at the Meeting to hold office until the next annual general meeting of shareholders or, if earlier, the election of his/her respective successor and (iii) has consented to being named as such and to serve as such if elected. We know of no reason why each of the nominees would not be available for election or, if elected, would be unable to serve. While we do not anticipate that any of the nominees will be unable to serve, if any should be unable to serve, the proxy holders reserve the right to substitute another person designated by the Board.

The resolutions in respect of this Proposal 1 are ordinary resolutions. The text of the resolutions in respect of Proposal 1 are as follows:

“IT IS RESOLVED, by separate resolutions, to elect the following director nominees to the board of directors of the Company: Gregory J. Divis, Dr. Eric J. Ende, Geoffrey M. Glass, Dr. Mark A. McCamish, Linda S. Palczuk and Peter J. Thornton.”

Vote Required and Board Recommendation

The affirmative vote of a majority of the votes cast on each resolution is required for the approval of each of the nominees. As this proposal is not considered a “routine item,” your bank, broker or other nominee cannot vote your shares without receiving your voting instructions. Abstentions and broker non-votes will not count either in favor of or against the proposal.

Non-Employee Directors

Set forth below is information for each nominee concerning the individual’s age, principal occupation, employment and directorships during the past five years, positions with the Company, the year in which he or she first became a director of the Company and his term of office as a director. Also set forth below is a brief discussion of the specific experience, qualifications, attributes or skills that led to the Board’s conclusion that, in light of our business and structure, each nominee should serve as a director as of the date of this Proxy Statement.

Geoffrey M. Glass, 49, has been a member of the Board since July 2018 and became Chair of the Board in December 2018. Since January 2021, Mr. Glass has served as the Chief Executive Officer of Kiniciti, LLC, a company that invests in non-therapeutic companies supporting cell and gene therapy innovation. He is also currently the Chairman of the Board at Ncardia, a drug discovery company focused on cardiovascular and neurological diseases, serving in that role since November of 2021. Further, since June of 2022, Mr. Glass has served as Chairman of the Board at Abzena, a biologics and bioconjugates development company. Mr. Glass has also been the Operating Partner at LongueVue Capital. Previously, he was the Chief Executive Officer (from January 2018 through September 2018), and a member of the board of directors (from November 2017 through December 2018), of Sancilio Pharmaceuticals, a specialty pharma company. Mr. Glass was also as a member of the board of directors for Locus Biosciences, a biotechnology company that develops CRISPR-engineered precision antibacterial products, from August 2015 to October 2017. From April 2009 to April 2015, Mr. Glass served as an executive committee member at Patheon N.V., a pharmaceutical contract development and manufacturing company. While at Patheon, he held a number of senior leadership roles including President of Banner Life Sciences (a Patheon subsidiary), Executive Vice President of Sales and Marketing, and Senior Vice President, Strategy, Corporate Development and Integration for Patheon. Before Patheon, Mr. Glass worked in various executive positions at Valeant Pharmaceuticals (now Bausch Health), including Senior Vice President, Asia Region, and Senior Vice President, Chief Information Officer, and in both roles was a member of the company’s executive committee. Mr. Glass began his career as a consultant in the life sciences practice for Capgemini Consulting (formerly EY Consulting). He received degrees in Economics and Political Science from the University of Arizona.

We believe Mr. Glass’s extensive management and financial experience makes him well qualified to serve as a director.

Dr. Eric J. Ende, 54, has been a member of the Board since December 2018. Dr. Ende is the President of Ende BioMedical Consulting Group, a privately held consulting company focused on the life sciences industry, a position he has held since 2009. Since May 2017, Dr. Ende has been a member of the board of directors of Matinas BioPharma, Inc., a clinical-stage biopharmaceutical company, where he is currently Chairman of the Board in addition to serving on the Nominating and Corporate Governance Committee. Dr. Ende also serves on the board of directors at Neubase Therapeutics, a company focused on genetic medicines development, and at Mount Sinai Innovation Partners Technology, a healthcare research and development organization. From November 2019 to June 2020, Dr. Ende served on the board of directors of Progenics Pharmaceuticals, Inc., a biopharmaceutical company. From January 2015 to October 2016, he served as Chairman of the Unsecured Creditor’s Committee in the bankruptcy of Egenix, Inc.

From 2002 through 2008, Dr. Ende was the senior biotechnology analyst at Merrill Lynch; from 2000 through 2002 he was the senior biotechnology

analyst at Bank of America Securities; and from 1997 to 2000 he was a biotechnology analyst at Lehman Brothers. Dr. Ende received an MBA in Finance and Accounting from NYU - Stern Business School in 1997, an MD from Mount Sinai School of Medicine in 1994, and a BS in Biology and Psychology from Emory University in 1990.

We believe Dr. Ende’s experience as a director for other pharmaceuticals companies makes him well qualified to serve as a director.

Dr. Mark A. McCamish, 71, has been a member of the Board since December 2019. Since November 2020, Dr McCamish has served as President, Chief Executive Officer and member of the board of directors of IconOVir Bio, Inc., a biotechnology company focused on development of oncolytic virus therapies.

We believe Dr. McCamish’s broad experience in the life sciences industry makes him well qualified to serve as a director.

Linda S. Palczuk, 61, has been a member of the Board since July 2018. From September 2019 to December 2022, Ms. Palczuk served as the Chief Operating Officer and a director of Envara Health, Inc., a medical nutrition technology company.

Prior to her position at Osiris Therapeutics, Ms. Palczuk had an extensive and successful 30-year career with AstraZeneca Pharmaceuticals and its legacy companies, serving in senior-level commercial and general management roles, including Vice President, Established Brands and Vice President, Global Commercial Excellence from January 2012 until March 2015, Vice President, Sales & Marketing from March 2009 to December 2011, and Vice President, Sales from April 2006 to February 2009.

Ms. Palczuk received a BA degree in Biology from Franklin and Marshall College and an MBA degree from the Alfred Lerner College of Business and Economics at the University of Delaware.

We believe Ms. Palczuk’s management experience makes her well qualified to serve as a director.

He is the President and Chief Financial Officer of Envetec Sustainable Technologies Limited, an Irish cleantech company focused on the carbon neutral treatment of biohazardous clinical material and plastics at source.

Prior to joining Technopath Clinical Diagnostics, from September 2011 to December 2013, Mr. Thornton was Senior Vice President - Business Integration for Alkermes plc, a global biopharmaceuticals company headquartered in Dublin, Ireland. From July 2007 to September 2011, he was Senior Vice President — Corporate and Business Development for Elan Drug Technologies, an Elan Corporation plc division engaged in developing and manufacturing drug delivery technology based pharmaceutical products.

Mr. Thornton worked for the international public accounting firm of KPMG for seven years in Ireland and France and is a fellow of Chartered Accountants Ireland. He holds a Bachelor of Commerce degree from University College Cork, Ireland.

We believe Mr. Thornton’s experience as a chief financial officer and his financial expertise make him well qualified to serve as a director.

EXECUTIVE COMPENSATION — COMPENSATION DISCUSSION AND ANALYSIS

Compensation Discussion and Analysis

In this Compensation Discussion and Analysis, we give an overview and analysis of our compensation philosophy, our compensation program, and the decisions we made in 2022 under those programs with respect to our named executive officers. Included in this discussion is specific information about the compensation earned or paid in 2021 and 2022 to our named executive officers (the “Named Executive Officers”). Named Executive Officers for 2022 are:

Name			Position
Gregory J. Divis			Chief Executive Officer
Richard J. Kim			Chief Commercial Officer
Thomas S. McHugh			Chief Financial Officer
Douglas Williamson			Former Chief Medical Officer

Compensation Philosophy and Objectives

The Compensation Committee’s executive compensation programs are designed to: (i) attract, retain and motivate executives with significant industry knowledge and the experience and leadership capability necessary for us to achieve success; (ii) align incentives for our named executive officers with our corporate strategies and business objectives and goals; and (iii) achieve key strategic performance measures aligned with the long-term interests of our shareholders.

Compensation Components

Our executive compensation program has three primary components: base salary, annual cash incentive awards and equity awards.

•

Base Salary. We fix the base salary of each of our executive officers at a level we believe enables us to hire and retain individuals in a competitive environment and rewards satisfactory individual performance and a satisfactory level of contribution to our overall business goals. We take into account the base salaries paid by similarly situated companies in our peer group and, to the extent practicable, we set base salary levels for similarly situated executives within the Company at comparable levels to avoid divisiveness and encourage teamwork, collaboration, and a cooperative working environment.

•

Cash Incentive Awards. We provide annual cash incentive awards that are based upon the achievement of corporate and individual objectives established by the Compensation Committee and the Board of Directors. These cash incentive awards are designed to focus our executive officers on achieving key clinical, regulatory, commercial, operational, strategic and financial objectives.

•

Equity Awards. We use stock options, restricted share units and performance share units to reward long-term performance. These equity awards are intended to provide significant incentive value for each executive officer if the Company performance is outstanding and the Company achieves its long-term goals to align executive compensation with long-term shareholder interests.

In addition to the primary components of compensation described above, we provide our Named Executive Officers with employee benefits that are generally available to our salaried employees. These benefits include health and medical benefits, flexible spending plans, matching 401(k) contributions and group life insurance.

We have also entered into agreements with our Named Executive Officers under which they are provided certain benefits in the event their employment with the Company is terminated without cause or by the Named Executive Officer for good reason, following a change in control of the Company.

Compensation Policies and Process

The Compensation Committee has oversight of our compensation philosophy and programs and annually reviews and recommends all compensation decisions relating to our Chief Executive Officer, our

TABLE OF CONTENTS

other Named Executive Officers and all other executive officers of the Company. The Chief Executive Officer provides specific information to the committee relative to the performance of the other members of the executive management team. However, the Chief Executive Officer is always excused from the Compensation Committee meetings when his compensation or employment is discussed. The Compensation Committee considers any recommendations by the Chief Executive Officer; however, the committee recommends final compensation for all executives. All compensation decisions are assessed within the framework of the Company’s financial position and general economic conditions. Our Board typically reviews and approves the compensation decisions made by the Compensation Committee.

Our Compensation Committee has engaged Aon’s Human Capital Solutions Practices, a division of Aon plc (“Aon”) specializing in executive compensation, as its independent compensation consultant. In connection with the Compensation Committee’s executive compensation decisions for 2022, Aon reviewed and advised on principal aspects of our executive compensation program and performed the following services:

•

conducted a competitive assessment of the Company’s then current executive compensation arrangements, including analyzing peer group Proxy Statements, compensation survey data, and other publicly available data;

•

provided recommendations on the composition of the Company’s peer group; and

•

reviewed and advised on equity compensation and on industry best practices.

The Compensation Committee has determined that the work of Aon and the individual compensation advisors employed by Aon does not create any conflict of interest. In making that determination, the Compensation Committee took into consideration the following factors: (i) the provision of other services to the Company by the consultant; (ii) the amount of fees the Company paid the consultant as a percentage of the consultant’s total revenue; (iii) the consultant’s policies and procedures that are designed to prevent conflicts of interest; (iv) any business or personal relationship of the consultant or the individual compensation advisors employed by the consultant with any Company executive officer; (v) any business or personal relationship of the individual compensation advisors with any member of the Compensation Committee; and (vi) any Company stock owned by the consultant or the individual compensation advisors employed by the consultant.

Peer Group

In an effort to provide competitive total compensation to our executive officers, the Compensation Committee approved a group of comparable companies as our peer group as recommended by Aon. The peer group was selected on the basis of similarity to the Company on the following criteria: business comparability, stage of product development and commercialization, number of employees, market capitalization and revenue. The following companies were identified as our “peer group” for 2022:

	2022 Peer Group
	Aeglea BioTherapeutics, Inc.			CymaBay Therapeutics, Inc.
	Albireo Pharma, Inc.			EyePoint Pharmaceuticals
	Aldeyra Therapeutics, Inc.			G1 Therapeutics, Inc.
	Ardelyx, Inc.			Liquidia

Say-on-Pay and Say-on-Frequency

We have developed a compensation policy that is designed to attract and retain key executives responsible for our success and motivate management to enhance long-term shareholder value. We believe our

TABLE OF CONTENTS

compensation policy strikes an appropriate balance between the implementation of responsible, measured compensation practices and the effective provision of incentives for our named executive officers to exert their best efforts for our success.

As required by Section 14A(a)(1) of the Exchange Act, periodically we must provide our shareholders with an opportunity to provide an advisory vote related to the compensation of our named executive officers, commonly known as the “say-on-pay” proposal. The SEC say-on-pay vote generally covers the calendar year prior to the date of our proxy statement. As such vote is advisory, it is not binding upon our Board or our Compensation Committee and neither the Board nor the Compensation Committee is required to take any action as a result of the outcome of such vote. However, our Compensation Committee carefully considers the outcome of this vote when considering future executive compensation policies.

As reported in our report on Form 8-K, filed with the SEC on August 5, 2022, at our 2022 annual general meeting, approximately 93% of the votes cast on our SEC Say-on-Pay proposal supported the compensation paid to our named executive officers. At our 2022 annual general meeting, we also held a separate non-binding advisory shareholder vote on the frequency of future shareholder advisory votes regarding the compensation program for our named executive officers, commonly referred to as a “say-on-frequency” vote. At the 2022 annual general meeting, our shareholders approved, on an advisory basis, a proposal to take the say-on-pay vote every two years until the next required say-on-frequency vote. Accordingly, our next say-on-pay vote will occur at the 2024 annual general meeting and our next say-on-frequency vote will occur at the 2028 annual general meeting.

Base Salary

The Company provides base salaries to attract and retain executives with the proper experiences and skill sets required to assist us in achieving our specific business objectives, as well as our future growth and success. Base salaries provide a guaranteed base level of compensation that reflects a belief that base salary for executive officers should be targeted at market-competitive levels. Base salaries for a particular fiscal year are generally established at the end of the prior year. In establishing the base salaries for 2022, the Compensation Committee considered each Named Executive Officer’s role and level of responsibility at the Company, recent individual performance, perceived impact on Company results and overall Company performance. The base salaries of our Named Executive Officers during 2021 and 2022 were as follows:

Name	2021 Base Salary ($)		2022 Base Salary ($)		Increase (%)
Gregory J. Divis		544,800		561,144		3%
Richard J. Kim(1)		425,000		437,750		3%
Thomas S. McHugh		396,550		420,343		6%
Douglas Williamson(2)		—		450,000		—

(1)

Mr. Kim was hired on February 15, 2021.

(2)

Mr. Williamson was hired on February 14, 2022, and his employment with us ended on August 15, 2022.

Annual Cash Incentive

The goal of the annual cash incentive program in 2022 was to align a meaningful portion of the total compensation potential for the Named Executive Officers to the achievement of specified quantitative and qualitative Company performance targets, as well as individual performance targets. The achievement of these targets advances the Company’s specific business objectives and result in long-term shareholder value. The target levels of the annual cash incentive awards were established as part of the Named Executive Officer’s individual employment agreements. Each of these employment agreements provides that the Named Executive Officer will receive an annual cash incentive award determined at the discretion of the Compensation Committee and the Board based on the Company’s performance against its objectives and individualized objective and subjective criteria, with a target award amount equal to a percentage of the Named Executive Officer’s base salary. The award criteria include specific objectives, relating to the achievement of clinical,

TABLE OF CONTENTS

regulatory, commercial, business and/or financial milestones. The table below sets forth each Named Executive Officer’s target incentive compensation for 2022:

Name	2022 Target Bonus (% of Base Salary)		2022 Target Bonus ($)		2022 Actual Bonus ($)(1)
Gregory J. Divis		60%		336,686		168,343
Richard J. Kim		45%		196,988		98,494
Thomas S. McHugh		45%		189,154		94,577
Douglas Williamson(2)		45%		202,500		—

(1)

50% of target achievement level was paid to our Named Executive Officers other than Mr. Williamson based on the Company’s performance.

(2)

Mr. Williamson began employment with us on February 14, 2022, and his employment with us ended on August 15, 2022. Accordingly, Mr. Williamson was not eligible to earn a bonus in 2022.

Our approved 2022 corporate goals consisted of:

•

Achieving LUMRYZ launch revenue and patient demand targets

•

Executing long range strategy and financial plan

•

Execution of portfolio and pipeline explanation

Following receipt of tentative approval of LUMRYZ from the FDA, the 2022 corporate goals were modified to the following:

•

Favorable DE Court decision ordering delisting of Jazz’s ‘963 REMS Patent

•

Achieving operating expense targets

•

Executing LUMRYZ launch preparations, including commercial supply

•

Completion of the LUMRYZ REMS buildout

•

Advancing pipeline

The Compensation Committee determined that the Company’s corporate performance score was 50% for 2022 based solely on the Compensation Committee’s assessment of the Company’s level of achievement against the approved 2022 corporate performance goals set forth above.

Mr. Divis’ 2022 annual cash incentive bonus was based entirely upon achievement of the corporate performance goals described above. Accordingly, the Compensation Committee awarded an aggregate annual cash incentive with respect to 2022 for Mr. Divis in the amount of $168,343.

The process for determining the annual cash incentive for our other Named Executive Officers is generally similar to what is described above with respect to our Chief Executive Officer. For 2022, the Compensation Committee took into account the Company’s performance with respect to the financial and strategic performance goals discussed above. The Compensation Committee assessed the individual performance of the other Named Executive Officers and also considered the recommendations of Mr. Divis. The other Named Executive Officers reported directly to Mr. Divis as Chief Executive Officer and so, the Compensation Committee believes, Mr. Divis was in a position to provide a meaningful assessment of their capabilities and contributions to the Company.

The Compensation Committee determined 2022 annual cash incentives for the other Named Executive Officers in the following amounts: Richard J. Kim - $98,494 and Thomas S. McHugh - $94,577. Mr. Williamson began employment with us on February 14, 2022, and his employment with us terminated on August 15, 2022. Accordingly, Mr. Williamson was not eligible to earn a bonus in 2022.

Equity Compensation

The Compensation Committee believes equity compensation awards help to align the interests of our executive officers with those of shareholders because the value of the equity awards to the recipient increases

TABLE OF CONTENTS

only with the appreciation of the price of our ordinary shares. Furthermore, the Compensation Committee believes granting equity awards that vest over time encourages executives to remain with the Company. The authority to grant equity awards to our executive officers lies with the Compensation Committee and Board. The Compensation Committee takes into consideration the peer group data provided by Aon and the recommendations of our Chief Executive Officer (other than for himself). Generally, the Compensation Committee has granted stock options to our executive officers upon commencement of their employment with the Company. In this regard, Mr. Williamson was awarded an option to purchase 275,000 shares of common stock of the Company in connection with his commencement of employment with us on February 14, 2022. This initial stock option grant was scheduled to vest over a four-year period and was in connection with the executive officer’s employment agreement.

In addition to new hire stock options, at least annually, the Compensation Committee considers annual equity awards for our executive officers. These awards may consist of stock options, restricted share units (“RSUs”), performance share units (“PSUs”) or performance stock options (“PSOs”). In August 2022, the Compensation Committee determined it would be appropriate to grant PSOs to our employees. The Compensation Committee believed that the grant of supplemental awards in the form of PSOs would further align our employees’ long-term incentive compensation with the interests of our shareholders. Specifically, the vesting of the PSOs is tied to the achievement of certain commercial milestones related to LUMRYZ and 50% vest upon the achievement of those milestones and the other 50% vest one year following achievement of those milestones. The following table below reflects the PSOs awarded to each of our Named Executive Officers (other than Mr. Williamson):

Name	Stock Options
Gregory J. Divis		350,000
Richard J. Kim		175,000
Thomas S. McHugh		175,000

In determining the number of stock options to grant to a particular Named Executive Officer, the Compensation Committee takes into account numerous factors, including: the executive’s role and level of responsibility within the Company, the Company’s performance with respect to the financial and strategic goals and objectives for that year, and comparative peer group data as presented by Aon. The Compensation Committee recognizes that stock options only have value if there is an increase in stock value after the date of grant.

Compensation Risk Assessment

The Company regularly reviews compensation plans and practices to ensure they are appropriately structured and aligned with business objectives, and not designed to encourage executives to take unwarranted risks. Specifically, the overall design of the compensation philosophy and plans mitigate risks because: (1) the financial performance objectives of the short and long-term incentive plans are reviewed and approved annually by the Board; (2) the plans consist of multiple performance objectives, thus lessening the focus on any one in particular; and (3) short and long-term incentive payouts are capped for all participants.

General Employee Benefits

Avadel offers competitive health, dental and life insurance and vacation pay for all employees, including Named Executive Officers. In addition, the senior executives are eligible to receive matching 401(k) plan contributions on the same basis as other employees.

Severance and Change-in-Control Benefits

Pursuant to employment agreements, each of our Named Executive Officers has a provision in his or her employment agreement with the Company that entitles such Named Executive Officer to certain specified benefits in the event of termination of their employment under specified circumstances, including termination following a change in control of the Company. These benefits are described in the “Employment Agreement”

TABLE OF CONTENTS

section below, and certain estimates of these severance and change-in-control benefits are provided in “Estimated Payments Upon Termination or Change in Control” below.

Retirement Benefits

The Company believes offering competitive retirement benefits is important to attract and retain top executives. The Company’s U.S.-based executives participate in a traditional defined contribution 401(k) plan. For our Company’s 401(k) plan, the Company generally contributed approximately $11,000 to $12,000 to each eligible executive’s 401(k) account during 2022, which was the maximum contribution match allowable under the Company’s 401(k) Plan, provided the participant contributed the maximum in order to receive the maximum match and contributed based off of $305,000 of wages, the maximum allowable under the IRS limits. Additional details regarding retirement benefits are provided in the tables below entitled “Summary Compensation Table.”

Deductibility of Executive Compensation

Generally, Section 162(m) of the Internal Revenue Code of 1986, as amended (the “Code”) disallows a federal income tax deduction for public corporations of remuneration in excess of $1 million paid for any fiscal year to “covered employees” of the Company. The Board and the Compensation Committee believe shareholder interests are best served if they retain maximum flexibility to design executive compensation programs that meet stated business objectives. For that reason, while our Board and Compensation Committee consider the potential effects of Section 162(m) of the Code on the compensation paid to our named executive officers, in light of the constraints imposed by Section 162(m) and our desire to maintain flexibility in compensation decisions, the Board and the Compensation Committee do not necessarily limit compensation to amounts deductible under Section 162(m).

Taxation of “Parachute” Payments

Sections 280G and 4999 of the Code provide that executive officers and directors who hold significant equity interests and certain other service providers may be subject to significant additional taxes if they receive payments or benefits in connection with a change in control of the Company that exceeds certain prescribed limits, and that the Company (or a successor) may forfeit a deduction on the amounts subject to this additional tax. Our compensation arrangements for executive officers, including our Named Executive Officers, do not provide tax gross-ups for any type of payments, including payments for severance or in connection with a change of control of the Company.

Securities Trading Policy

The Company has a policy that prohibits executive officers and directors from trading in the Company’s securities while aware of material non-public information or engaging in hedging transactions or short sales and trading in “puts” and “calls” involving the Company’s securities. This policy is described in our Code of Conduct, which may be viewed on our website at https://www.avadel.com/corporate-compliance. In addition, executive officers and directors are prohibited from pledging the Company’s securities.

Represents salaries before any employee contributions under our 401(k) Plan. Mr. Williamson joined us in February 2022 and left us in August 2022. Mr. Kim joined us in February 2021 and, accordingly, their salaries for 2022 and 2021, respectively, reflect their partial years of service.

(2)

Represents the aggregate grant date fair value of share awards granted in 2022, 2021 and 2020, respectively, calculated in accordance with FASB ASC Topic 718. For a full description of the assumptions we use in calculating these amounts, see Note 14 to our consolidated financial statements for the year ended December 31, 2022 which are included in our Annual Report on Form 10-K filed with the SEC on March 29, 2023. The actual value a Named Executive Officer may receive depends on market prices and there can be no assurance that the amounts reflected in the Stock Awards column will actually be realized. For 2021 and 2020, the amounts reported in this table do not include the grant date fair value of the PSUs, as achievement was not probable on the grant date. Assuming maximum achievement, the grant date fair value of the PSUs granted in 2021 to each of Mr. Divis, Mr. McHugh and Mr. Kim for 2021 would have been $1,389,900, $492,000 and $451,004, respectively. Assuming maximum achievement, the grant date fair value of the PSUs granted in 2020 to each of Mr. Divis and Mr. McHugh would have been $1,392,720 and $497,400, respectively. All PSUs were forfeited in 2022.

Amounts reported reflect the aggregate grant date fair value of options granted or modified in 2022, 2021 and 2020, respectively, calculated in accordance with FASB ASC Topic 718. For a full description of the assumptions we use in calculating these amounts, see Note 14 to our consolidated financial statements for the year ended December 31, 2022 which are included in our Annual Report on Form 10-K filed with the SEC on March 29, 2023. The actual value a Named Executive Officer may receive depends on market prices and there can be no assurance that the amounts reflected in the Option Awards column will actually be realized. No gain to a named executive officer is possible without an appreciation in stock value after the date of grant. For 2022, the amounts reported in this table to Mr. Divis, Mr. McHugh and Mr. Kim do not include the grant date fair value of the PSOs, as achievement was not probable on the grant date. Assuming maximum achievement, the grant date fair value of the PSOs granted in 2022 to each of Mr. Divis, Mr. McHugh and Mr. Kim would have been $1,297,738, $648,869 and $648,869, respectively.

Employment Agreements

We have written employment agreements with each of our Named Executive Officers (other than Mr. Williamson), whose employment with us ended in August 2022), which were each amended on September 28, 2022. Each employment agreement provides that the individual’s employment will continue until either we or the Named Executive Officer provides written notice of termination in accordance with the terms of the agreement. In addition, each of these agreements prohibit the Named Executive Officer from disclosing confidential information and competing with us during the term of their employment with the Company and for a specified time period thereafter. The agreements also contain customary non-solicitation and non-disparagement provisions. Under the terms of their respective employment agreements, each of the Named Executive Officers is entitled to receive an annual base salary, subject to annual review, an annual cash incentive and an annual equity award, each component of which is subject to the discretion of our board.

Payments upon Termination of Employment

Pursuant to their employment agreements, each of our Named Executive Officers is entitled to certain severance benefits in the event he or she terminates his or her employment for “Good Reason” or if his or her employment is terminated by the Company for any reason other than for “Cause,” including non- renewal by the Company at the end of the employment term. Upon such a termination, each of the Named Executive Officers is entitled to receive all accrued but unpaid bonuses for any completed fiscal year and vacation pay, expense reimbursement and other benefits due under any Company-provided benefit plans, policies and arrangements. In addition, Mr. Divis is entitled to receive: (1) severance equal to 1.5 times his base salary, payable in substantially equal installments in accordance with the Company’s normally payroll practices; and (2) payment of monthly COBRA health insurance premiums for up to 18 months, and Mr. Kim and Mr. McHugh are entitled to receive (1) severance equal to 1.0 times their base salary, payable in substantially equal installments in accordance with the Company’s normally payroll practices; and (2) payment of monthly COBRA health insurance premiums for up to 12 months.

In addition to the above, if such a termination occurs during a Change in Control Period (as defined below), Mr. Divis is entitled to receive (i) the highest of (x) his target bonus in effect for the fiscal year in which the applicable change in control occurs, (y) his target bonus in effect for the fiscal year in which the termination of employment occurs; or (z) his actual bonus for performance during the calendar year prior to the calendar year during which the termination of employment occurs.

TABLE OF CONTENTS

For purposes of each of the Named Executive Officer’s agreements:

•

“Good Reason” is defined as

•

For Mr. Divis: (i) the failure of the Company to timely pay to the employee any compensation owed under the agreement; (ii) the Company’s diminution in the employee’s authority, duties or responsibilities in any material respect or the Company’s assignment to the employee of duties that are materially inconsistent with the duties stated in the agreement; (iii) the relocation of the place of the employee’s employment more than sixty (60) miles outside the greater St. Louis metropolitan area; (iv) a material breach by the Company of the agreement; or (v) the failure of the Company to have the agreement assumed in full by any successor in the case of any merger, consolidation, or sale of all or substantially all of the assets of the Company.

•

“Cause” means: (i) conviction of or plea of nolo contendere to a felony or crime involving moral turpitude; (ii) fraud, theft, or misappropriation of any asset or property of the Company, including, without limitation, any theft or embezzlement or any diversion of any corporate opportunity; (iii) breach of any of the material obligations contained in the agreement; (iv) conduct materially contrary to the material policies of the Company; (v) material failure to meet the goals and objectives established by the Company without cure within a reasonable period of time after written notice thereof; or (vi) conduct that results in a material detriment to the Company, its program, or goals or is inimical to the Company’s reputation and interests without cure within a reasonable period of time after written notice thereof.

“Change of Control” means the occurrence of any of the following events: (i) A change in the ownership of the Company which occurs on the date that any one person, or more than one person acting as a group (‘Person’), acquires ownership of the equity interests of the Company that, together with the shares held by such Person, constitutes more than fifty percent (50%) of the total voting power of the shares of the Company; provided, however, that for purposes of this subsection, the acquisition of additional shares by any one Person, who is considered to own more than fifty percent (50%) of the total voting power of the shares of the Company will not be considered a Change or Control; or (ii) A change in the effective control of the Company which occurs on the date that a majority of the members of the Board is replaced during any twelve (12) month period by Directors whose appointment or election is not endorsed by a majority of the members of the Board prior to the date of the appointment or election. For purposes of such definition, if any Person is considered to be in effective control of the Company, the acquisition of additional control of the Company by the same Person will not be considered a Change of Control; or (iii) A change in the ownership of a substantial portion of the Company’s assets which occurs on the date that any Person acquires (or has acquired during the twelve (12) month period ending on the date of the most recent acquisition by such person or persons) assets from the Company that have a total gross fair market value equal to or more than fifty percent (50%) of the total gross fair market value of all of the assets of the Company immediately prior to such acquisition or acquisitions.

The benefits provided are designed to protect earned benefits in the case that one or more of such Named Executive Officers is terminated without cause or as a result of a Change in Control of the Company, in order to encourage such Named Executive Officers to act in the best interests of the shareholders at all times during the course of a change in control transaction or other significant event involving our Company.

COMPENSATION COMMITTEE REPORT

The Compensation Committee has reviewed and discussed the Compensation Discussion and Analysis required by Item 402(b) of Regulation S-K with management and, based on such review and discussion, the Compensation Committee recommended to the Board that it be included in this Proxy Statement.

THE COMPENSATION COMMITTEE
Linda S. Palczuk, Chair
Dr. Mark A. McCamish
Peter J. Thornton

The “Compensation Committee Report” above shall not be deemed incorporated by reference by any general statement incorporating this Proxy Statement into any filing under the Securities Act of 1933 or under the Securities Exchange Act of 1934, as amended, except to the extent that we specifically incorporate this information by reference and shall not otherwise be deemed filed under such Acts.

Compensation Risk Assessment

As part of its oversight of our executive compensation program, the Compensation Committee considers the impact of our executive compensation program, and the incentives created by the compensation awards that it administers, on our risk profile. In addition, we review all our compensation policies and procedures, including the incentives that they create and factors that may reduce the likelihood of excessive risk-taking, to determine whether they present a significant risk to us. The Compensation Committee concluded that our compensation programs are designed with the appropriate balance of risk and reward in relation to our overall business strategy and that the balance of compensation elements discourages excessive risk-taking. The Compensation Committee, therefore, determined that the risks arising from our compensation policies and practices for employees are not reasonably likely to have a material adverse effect on us. The Compensation Committee will continue to consider compensation risk implications while deliberating the design of our executive compensation programs. In its discussions, the Compensation Committee considered the attributes of our programs, including:

•

Appropriate pay philosophy in light of our business model;

•

Balance with respect to the mix of cash and equity compensation, and measures of performance against both annual and multi-year standards;

•

Short and long-term incentives linked to share price performance;

•

Performance goals are set at levels that are sufficiently high to encourage strong performance and support the resulting compensation expense, but within reasonably attainable parameters to discourage pursuit of excessively risky business strategies;

•

Long-term incentives generally have multi-year vesting to ensure a long-term focus and appropriate balance against short-term goals;

•

Independent Compensation Committee oversight, with Compensation Committee discretion to reduce incentives based on subjective evaluation of individual performance; and

•

Anti-hedging/pledging policies.

PAY RATIO DISCLOSURE

Under Section 953(b) of the Dodd-Frank Wall Street Reform and Consumer Protection Act and Item 402(u) of Regulation S-K, the Company is required to provide the ratio of the annual total compensation of Mr. Divis, who is the Company’s Chief Executive Officer, to the annual total compensation of the median employee of the Company (the “Pay Ratio Disclosure”).

For fiscal year 2022, the median annual total compensation of all employees of the Company and its consolidated subsidiaries (other than the Chief Executive Officer) was $244,878. Mr. Divis’ annual total compensation for fiscal year 2022 was $753,687. Based on this information, for fiscal year 2022, the ratio of the compensation of the Chief Executive Officer to the median annual total compensation of all other employees was estimated to be 3 to 1.

To identify, and to determine the annual total compensation of, the median employee, we used the following methodology:

•

We collected the payroll data of all employees globally, whether employed on a full-time, part-time, temporary or seasonal basis as of December 31, 2022.

•

We annualized the compensation of all permanent full-time and part-time employees who were hired by the Company and its consolidated subsidiaries between January 1, 2022, and December 31, 2022.

•

We then identified our median employee from our employee population based on this compensation measure.

The median employee’s annual total compensation represents the amount of such employee’s compensation for fiscal year 2022 that would have been reported in the Summary Compensation Table in accordance with the requirements of Item 402(c)(2)(x) of Regulation S-K if the employee was a Named Executive Officer, and the annual total compensation of the Chief Executive Officer represents the amount reported in the “Total” column of our 2022 Summary Compensation Table on page 38 of this Proxy Statement.

Using this methodology, we determined that the median employee was a new hire with anomalous compensation. Therefore, we substituted another employee with compensation closest to our estimate used to identify the medial employee. This employee is an exempt, full-time employee located in the United States with an annual total compensation of $244,878 for fiscal year 2022, calculated in accordance with the requirements of Item 402(c)(2)(x) of Regulation S-K, which includes base pay, stock and option awards, non-equity incentive plan compensation and the Company’s contribution to that employee’s retirement plan.

The Pay Ratio Disclosure presented above is a reasonable estimate. Because the SEC rules for identifying the median employee and calculating the pay ratio allow companies to use different methodologies, exemptions, estimates and assumptions, the Pay Ratio Disclosure may not be directly comparable to the pay ratio reported by other companies.

TABLE OF CONTENTS

PAY VERSUS PERFORMANCE DISCLOSURE

As required by the Dodd-Frank Act and Item 402(v) of Regulation S-K, the Pay versus Performance disclosure that follows provides information about the relationship between Compensation Actually Paid, or CAP, to our principal executive officer, or PEO, and Non-PEO NEOs and certain financial performance measures of the company. For the most recently completed fiscal year, the Company did not use any “financial performance measures” as defined in Item 402(v) of Regulation S-K to link compensation paid to our Named Executive Officers, or NEOs, to the Company’s performance. We are also permitted to report as a “smaller reporting company” as defined under the U.S. federal securities laws. Accordingly, we have not included a tabular list of financial performance measures, and the table below does not include a column for a “Company-Selected Measure” as defined in Item 402(v) of Regulation S-K. See the Compensation Discussion and Analysis within this proxy statement for further information concerning the company’s variable pay-for-performance philosophy and how the company aligns executive compensation with company performance.

Relationship Between Financial Performance Measures

While the Company utilizes several performance measures to align executive compensation with Company performance, all of those Company measures are not presented in the Pay versus Performance table. Moreover, the Company generally seeks to incentivize long-term performance, and therefore does not specifically align the Company’s performance measures with compensation that is actually paid (as computed in accordance with SEC rules) for a particular year. The graphs below illustrate the relationship between compensation actually paid to our PEO and the average of the compensation actually paid to our remaining NEOs, with (i) our cumulative TSR and (ii) our net income, in each case, for the fiscal years ended December 31, 2022, December 31, 2021, and December 31, 2020. TSR amounts reported in the graph assume an initial fixed investment of $100, and that all dividends, if any, were reinvested.

CERTAIN RELATIONSHIPS AND RELATED PARTY TRANSACTIONS

Policies and Procedures for Related Person Transactions

The Audit Committee reviews all related party transactions and similar matters to the extent required by listing standards. The Nominating and Corporate Governance Committee further assists to ensure that all such related party transactions are thoroughly reviewed on a regular basis so that such transactions are and remain at arms’ length terms, thus promoting long term shareholder value.

For purposes of related person transactions as managed by our Audit and Nominating and Corporate Governance Committees, a “related person transaction” is a transaction, arrangement or relationship (or any series of similar transactions, arrangements or relationships) in which we (or any of our subsidiaries) were, are or will be a participant, and the amount involved exceeds $120,000 and in which any related person had, has or will have a direct or indirect interest. For purposes of determining whether a transaction is a related person transaction, the Committees rely upon Item 404 of Regulation S-K, promulgated under the Securities Exchange Act of 1934, as amended.

A “related person” is defined as:

•

Any person who is, or at any time since the beginning of our last fiscal year was, one of our directors or executive officers or a nominee to become one of our directors;

•

Any person who is known to be the beneficial owner of more than five percent of any class of our voting securities;

•

Any immediate family member of any of the foregoing persons, which means any child, stepchild, parent, stepparent, spouse, sibling, mother-in-law, father-in-law, son-in-law, daughter-in-law, brother- in-law or sister-in-law of the director, executive officer, nominee or more than five percent beneficial owner, and any person (other than a tenant or employee) sharing the household of such director, executive officer, nominee or more than five percent beneficial owner; and

Any firm, corporation, or other entity in which any of the foregoing persons is employed or is a general partner or principal or in a similar position or in which such person has a ten percent or greater beneficial ownership interest.

Related Party Transactions

Other than as described below and the compensation agreements and other arrangements described under the sections of this proxy statement titled “Executive Compensation” and “Director Compensation,” since January 1, 2022, there has not been and there is not currently proposed, any transaction or series of similar transactions to which we were, or will be, a party in which the amount involved exceeded, or will exceed, $120,000 and in which any director, executive officer, holder of five percent or more of any class of any class of our voting securities or any member of the immediate family of, or entities affiliated with, any of the foregoing persons, had, or will have, a direct or indirect material interest.

2023 Public Offering

In April 2023, we closed a registered public offering pursuant to which we issued and sold an aggregate of 12,205,883 ordinary shares, in the form of ADSs (including up to 2,205,882 ordinary shares, in the form of ADSs sold pursuant to the underwriter’s full exercise of its option to purchase additional ADSs) at a public offering price of $8.50 per ADS and (ii) an aggregate of 4,705,882 Series B Non-Voting Convertible Preferred Shares (“Series B Preferred Shares”) at a public offering price of $8.50 per Series B Preferred Share (the “Offering”). The following table sets forth the number of securities purchased in the Offering by holders of five percent or more of our securities:

PROPOSAL 2
A NON-BINDING RATIFICATION OF THE APPOINTMENT OF DELOITTE & TOUCHE LLP AND BINDING AUTHORIZATION OF THE AUDIT COMMITTEE OF THE BOARD TO SET THE AUDITORS’ REMUNERATION
(Ordinary Resolution)

ITEM 2 ON PROXY CARD

Pursuant to this proposal, the Company seeks shareholder ratification, in a non-binding vote, of the appointment of Deloitte & Touche LLP (“Deloitte”) as the Company’s independent registered public auditor and accounting firm for the fiscal year ending December 31, 2023, and authorization, in a binding vote, of the Audit Committee of the Board to set the independent registered public auditor and accounting firm remuneration.

Background

In 2022, the Audit Committee approved the engagement of Deloitte to serve as the Company’s independent registered public accounting firm for the fiscal year 2022, for purposes of the Company’s financial statements for filing under U.S. securities law for the year ending December 31, 2022. At the 2022 annual general meetings of shareholders, the shareholders voted to ratify the selection of Deloitte as the Company’s independent registered accounting firm for the fiscal year 2022. Pursuant to its charter, the Audit Committee approved in advance each professional service performed by Deloitte during fiscal year 2022 and considered the possible effect of the provision of such service on the auditors’ independence. Information relating to fees paid to Deloitte is set forth in the table below.

Under the Sarbanes-Oxley Act of 2002 and the rules of the SEC promulgated thereunder, the Audit Committee is solely responsible for the selection, appointment, compensation and oversight of the work of our independent registered public accounting firm. Although submission of the appointment of an independent registered public accounting firm to shareholders for ratification is not required by law, the Board considers the appointment of our independent registered public accounting firm to be an important matter of shareholder concern and is submitting the appointment of Deloitte for ratification by our shareholders, as a matter of good corporate practice.

It is not expected that any representatives of Deloitte will be present at the Meeting and, accordingly, no such representatives will have the opportunity to make a statement at the Meeting, if they desire to do so, nor, therefore, will any representative of Deloitte be available at the Meeting to respond to appropriate questions.

The Board has not determined what action it would take if the shareholders do not approve the selection of Deloitte but may reconsider its selection if the shareholders’ action so warrants. Even if the selection is ratified, the Audit Committee, exercising its own discretion, may select different auditors at any time during the year if it determines that such a change would be in the Company’s best interests and in the best interests of our shareholders.

The resolution in respect of this Proposal 2 is an ordinary resolution. The text of the resolution in respect of Proposal 2 is as follows:

“IT IS RESOLVED, to ratify the appointment of Deloitte & Touche LLP as the independent registered public accounting firm and auditors of Avadel Pharmaceuticals plc for the fiscal year ending December 31, 2023, and to authorize, in a binding vote, the Audit Committee to set such independent auditor and accounting firm’s remuneration.”

Required Vote and Board Recommendation

The affirmative vote of a majority of the votes cast on the matter is required for the approval of this item. As this proposal is considered a “routine item,” your bank, broker or other nominee may vote your shares “FOR” the proposal without receiving your voting instructions. Abstentions and broker non-votes will not count either in favor of or against the proposal.

THE BOARD RECOMMENDS THAT YOU VOTE “FOR” THE RATIFICATION OF THE APPOINTMENT OF DELOITTE & TOUCHE LLP AS THE INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM FOR THE FISCAL YEAR ENDING DECEMBER 31, 2023 AND TO AUTHORIZE THE AUDIT COMMITTEE OF THE BOARD TO SET THE AUDITORS’ REMUNERATION.

TABLE OF CONTENTS

AUDIT COMMITTEE REPORT

Pursuant to SEC rules for Proxy Statements, the Audit Committee of the Board has prepared the following Audit Committee Report. The Audit Committee intends that this report clearly describe our current audit program, including the underlying philosophy and activities of the Audit Committee.

Composition, Qualifications and Governance

The Board has an Audit Committee comprised solely of independent directors, namely Peter J. Thornton (Chair), Dr. Eric J. Ende, Geoffrey M. Glass, and Dr. Mark A. McCamish. The Audit Committee operates under a written charter adopted by the Board. The Audit Committee’s responsibilities are set forth in this charter, which was amended and restated effective August 14, 2020. The Audit Committee reviews and assesses the adequacy of its charter at least annually, and, when appropriate, recommends changes to the Board for review and approval. The charter is available at https://investors.avadel.com/corporate-governance/highlights.

Responsibilities and Duties

The Audit Committee assists the Board in fulfilling its responsibilities for general oversight of the integrity of the Company’s financial statements, the adequacy of the Company’s system of internal controls and procedures and disclosure controls and procedures, the Company’s risk management, the Company’s compliance with legal and regulatory requirements, the independent auditors’ qualifications and independence and the performance of the Company’s internal audit function and independent auditors. The Audit Committee recommends to the Board the selection of the Company’s independent auditors and manages the Company’s relationship with its independent auditors (who report directly to the Audit Committee). The Audit Committee has the authority to obtain advice and assistance from outside legal, accounting or other advisors as the Committee deems necessary to carry out its duties and receive appropriate funding, as determined by the Audit Committee, from the Company for such advice and assistance.

The Audit Committee met four times during 2022. The Audit Committee schedules its meetings with a view to ensuring that it devotes appropriate attention to all of its tasks. The Audit Committee’s meetings include private sessions with either the Company’s independent auditors or internal auditors when necessary, without the presence of the Company’s management, as well as executive sessions consisting of only Audit Committee members. In addition to the scheduled meetings, senior management confers with the Audit Committee or its Chair from time to time, as senior management deems advisable or appropriate, in connection with issues or concerns that arise throughout the year. The Audit Committee Chair also holds meetings with the Company’s Chief Financial Officer on a regular basis.

Management is responsible for the Company’s financial reporting process, including its system of internal control over financial reporting, and for the preparation of consolidated financial statements in accordance with accounting principles generally accepted in the U.S. The Company’s independent auditors are responsible for auditing those financial statements in accordance with professional standards and expressing an opinion as to their material conformity with U.S. generally accepted accounting principles and for auditing the effectiveness of the Company’s internal control over financial reporting. The Audit Committee’s responsibility is to monitor and review the Company’s financial reporting process and discuss management’s report on the Company’s internal control over financial reporting. It is not the Audit Committee’s duty or responsibility to conduct audits or accounting reviews or procedures. The Audit Committee has relied, without independent verification, on management’s representations that the financial statements have been prepared with integrity and objectivity and in conformity with accounting principles generally accepted in the U.S. and with respect to whether the Company’s internal control over financial reporting is effective. The Audit Committee has also relied, without independent verification, on the opinion of the independent auditors included in their report regarding the Company’s financial statements and effectiveness of internal control over financial reporting.

Matters Discussed with Management and Independent Auditors

As part of its oversight of the Company’s financial statements, the Audit Committee reviews and discusses with both management and the Company’s independent auditors all annual and quarterly financial statements prior to their issuance. During 2022, management advised the Audit Committee that each set of financial statements reviewed had been prepared in accordance with accounting principles generally accepted in the

TABLE OF CONTENTS

U.S. and reviewed significant accounting and disclosure issues with the Audit Committee. These reviews included discussions with the independent auditors of matters required to be discussed pursuant to Public Company Accounting Oversight Board (“PCAOB”) Auditing Standard No. 16 (Communication with Audit Committees), including the quality (not merely the acceptability) of the Company’s accounting principles, the reasonableness of significant judgments, the clarity of disclosures in the financial statements and disclosures related to critical accounting practices. The Audit Committee has also discussed with Deloitte & Touche LLP matters relating to its independence, including a review of audit and non-audit fees and the written disclosures and letter received from Deloitte & Touche LLP required by applicable requirements of the PCAOB regarding Deloitte & Touche LLP’s communications with the Audit Committee concerning independence. The Audit Committee also considered whether any non-audit services provided by the independent auditors are compatible with the independent auditors’ independence. The Audit Committee also received regular updates, and written summaries as required by the PCAOB rules (for tax and other services), on the amount of fees and scope of audit, audit-related, tax and other services provided.

In addition, the Committee reviewed key initiatives and programs aimed at strengthening the effectiveness of the Company’s internal and disclosure control structure. As part of this process, the Committee continued to monitor the scope and adequacy of the Company’s internal auditing program, reviewing staffing levels and steps taken to implement recommended improvements in internal procedures and controls. The Committee also reviews and discusses legal and compliance matters with management, and, as necessary or advisable, the Company’s independent auditors.

Based on the Audit Committee’s discussions with management and the independent auditors and the Audit Committee’s review of the representations of management and the report of the independent auditors to the Board, and subject to the limitations on the Audit Committee’s role and responsibilities referred to above and in the Audit Committee charter, the Audit Committee recommended to the Board, and the Board has approved, the audited consolidated financial statements of the Company be included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2022 for filing with the SEC.

PROPOSAL 3
TO AMEND THE AVADEL PHARMACEUTICALS PLC 2020 OMNIBUS INCENTIVE COMPENSATION PLAN
(Ordinary Resolution)

ITEM 3 ON PROXY CARD

Proposal

The Board believes that share-based incentive awards can play an important role in the success of the Company by encouraging and enabling the employees, officers, non-employee directors and consultants of the Company and its subsidiaries upon whose judgment, initiative and efforts the Company largely depends for the successful conduct of its business to acquire a proprietary interest in the Company. The Board believes that providing such persons with a direct stake in the Company assures a closer identification of the interests of such individuals with those of the Company and its shareholders, thereby stimulating their efforts on the Company’s behalf and strengthening their desire to remain with the Company.

On April 17, 2023, upon the recommendation of the Compensation Committee, the Board approved an amendment (the “Amendment”) of the Avadel Pharmaceuticals plc 2020 Omnibus Incentive Compensation Plan (as amended, the “2020 Plan”), subject to shareholder approval. The Amendment, among other things, increases the aggregate number of shares authorized for issuance under the 2020 Plan by 6,500,000 shares.

The 2020 Plan was designed to enhance the flexibility to grant equity awards to our officers, employees, non-employee directors and consultants and to ensure that we can continue to grant equity awards to eligible recipients at levels determined to be appropriate by the Board and/or the Compensation Committee.

Summary of Material Features of the 2020 Plan

If this Proposal 3 is approved by our shareholders, the material features of the 2020 Plan, as amended, are:

•

The maximum number of ordinary shares that can be issued under the 2020 Plan is 12,500,000;

•

The maximum number of shares of ordinary shares that can be issued under the 2020 Plan as incentive stock options is 12,500,000;

•

All full-time and part-time officers, employees, non-employee directors and consultants are eligible to participate in the 2020 Plan, subject to the discretion of the administrator;

•

The award of share options (both incentive and non-qualified options), share appreciation rights, restricted shares, restricted stock units, unrestricted shares, cash-based awards, and dividend equivalent rights is permitted;

•

Shares reacquired on the open market will not be added to the reserved pool under the 2020 Plan;

•

Shares tendered or held back for taxes will not be added back to the reserved pool under the 2020 Plan. Upon the exercise of a share appreciation right that is settled in ordinary shares, the full number of shares underlying the award will be charged to the reserved pool. Additionally, shares we reacquire on the open market will not be added to the reserved pool under the 2020 Plan;

•

Share options and share appreciation rights will not be repriced in any manner without shareholder approval;

•

The value of all awards awarded under the 2020 Plan and all other cash compensation paid by us to any non-employee director in any calendar year may not exceed $675,000;

•

A minimum vesting period of one year is required for all equity awards, other than a limited number of excepted awards under the 2020 Plan;

•

Any dividends and dividend equivalent rights payable with respect to any equity award are subject to the same vesting provisions as the underlying award;

•

Any material amendment to the 2020 Plan is subject to approval by our shareholders; and

TABLE OF CONTENTS

•

The term of the 2020 Plan will expire on August 5, 2030.

Based solely on the closing price of our ADSs as reported by Nasdaq on April 7, 2023 and the maximum number of shares that would have been available for awards as of such date under the 2020 Plan, as amended, the maximum aggregate market value of the ordinary shares that could potentially be issued under the 2020 Plan, as amended, is $60,946,841. The ordinary shares underlying any awards that are forfeited, canceled or otherwise terminated, other than by exercise, under the 2020 Plan and our Avadel Pharmaceuticals plc 2017 Omnibus Incentive Compensation Plan will be added back to the ordinary shares available for issuance under the 2020 Plan. Shares tendered or held back upon exercise of a share option or settlement of an award under the 2020 Plan to cover the exercise price or tax withholding and (ii) shares subject to a share appreciation right that are not issued in connection with the share settlement of the share appreciation right upon exercise thereof, will not be added back to the ordinary shares available for issuance under the 2020 Plan. In addition, shares repurchased on the open market will not be added back to the shares available for issuance under the 2020 Plan.

Rationale for Share Increase

The 2020 Plan is critical to our ongoing effort to build shareholder value. Equity incentive awards are an important component of our executive and non-executive employees’ compensation. Our Compensation Committee and the Board believe that we must continue to offer a competitive equity compensation program in order to attract, retain and motivate the talented and qualified employees necessary for our continued growth and success.

We manage our long-term shareholder dilution by limiting the number of equity incentive awards granted annually. The Compensation Committee carefully monitors our annual net burn rate, total dilution and equity expense in order to maximize shareholder value by granting only the number of equity incentive awards that it believes are necessary and appropriate to attract, reward and retain our employees. Our compensation philosophy reflects broad-based eligibility for equity incentive awards for high performing employees. By doing so, we link the interests of those employees with those of our shareholders and motivate our employees to act as owners of the business.

Our Compensation Committee determined the size of the reserved pool under the 2020 Plan based on projected equity awards to anticipated new hires, projected annual equity awards to existing employees and an assessment of the magnitude of increase that our institutional investors and the firms that advise them would likely find acceptable. We anticipate that if our request to increase the share reserve is approved by our shareholders, it will be sufficient to provide equity incentives to attract, retain, and motivate employees.

The following table provides information as of April 7, 2023, regarding ordinary shares that may be issued under our equity compensation plans, consisting of our 2017 Omnibus Incentive Compensation Plan (the “2017 Omnibus Plan”), our 2020 Omnibus Incentive Compensation Plan (the “2020 Omnibus Plan”), and our 2021 Inducement Plan (the “Inducement Plan”). As of April 7, 2023, there were 76,683,391 ordinary shares outstanding.

Summary of the 2020 Plan

The following description of certain features of the 2020 Plan, as amended, is intended to be a summary only. The summary is qualified in its entirety by the full text of the 2020 Plan, and the amendment to the 2020 Plan, which is attached hereto as Annex A.

Administration. The 2020 Plan will be administered by the Compensation Committee. The Compensation Committee has full power to select, from among the individuals eligible for awards, the individuals to whom awards will be granted, to make any combination of awards to participants, and to determine the specific terms and conditions of each award, subject to the provisions of the 2020 Plan. The Compensation Committee may delegate to a committee consisting of one or more officers of the Company the authority to grant awards to employees who are not subject to the reporting and other provisions of Section 16 of the Exchange Act, subject to certain limitations and guidelines.

Eligibility; Plan Limits. All full-time and part-time officers, employees, non-employee directors and consultants are eligible to participate in the 2020 Plan, subject to the discretion of the administrator. As of April 7, 2023, approximately 63 individuals would be eligible to participate in the 2020 Plan, which includes three executive officers, 60 employees who are not executive officers, five non-employee directors and zero consultants. There are certain limits on the number of awards that may be granted under the 2020 Plan. For example, no more than 6,500,000 shares may be granted in the form of incentive share options.

Director Compensation Limit. The 2020 Plan provides that the value of all awards awarded under the 2020 Plan and all other cash compensation paid by the Company to any non-employee director in any calendar year shall not exceed $675,000.

Minimum Vesting Period. The minimum vesting period for each equity award granted under the 2020 Plan must be at least one year, provided (1) that up to 5% of the shares authorized for issuance under the 2020 Plan may be utilized for unrestricted share awards or other equity awards with a minimum vesting period of less than one year and (2) annual awards to non-employee directors that occur in connection with the Company’s annual meeting of shareholders may vest on the date of the Company’s next annual meeting of shareholders. In addition, the Administrator may grant equity awards that vest within one year (i) if such awards are granted as substitute awards in replacement of other awards (or awards previously granted by an entity being acquired (or assets of which are being acquired)) that were scheduled to vest within one year or (ii) if such awards are being granted in connection with an elective deferral of cash compensation that, absent a deferral election, otherwise would have been paid to the grantee within the one year.

Share Options. The 2020 Plan permits the granting of (1) options to purchase ordinary shares intended to qualify as incentive share options under Section 422 of the Code and (2) options that do not so qualify. Options granted under the 2020 Plan will be non-qualified options if they fail to qualify as incentive options or exceed the annual limit on incentive share options. Incentive share options may only be granted to employees of the Company and its subsidiaries. Non-qualified options may be granted to any persons eligible to receive incentive options and to non-employee directors and consultants. The option exercise price of each option will be determined by the Compensation Committee. Except in the case of options (i) granted pursuant to a transaction described in, and in a manner consistent with, Section 424(a) of the Code, (ii) granted to individuals who are not subject to U.S. income tax on the date of grant or (iii) that are compliant with Section 409A of the Code, the exercise price of an option may not be less than 100% of the fair market value of the ordinary shares on the date of grant. Fair market value for this purpose will be determined by reference to the price of the ADSs on Nasdaq/the New York Stock Exchange or other foreign or national securities exchange or established market. The exercise price of an option may not be reduced after the date of the option grant without shareholder approval, other than to appropriately reflect changes in our capital structure.

TABLE OF CONTENTS

The term of each option will be fixed by the Compensation Committee and may not exceed ten years from the date of grant (provided that any options granted with an exercise price less than 100% of fair market value to Irish taxpayers must have a term not exceeding seven years). The Compensation Committee will determine at what time or times each option may be exercised. Options may be made exercisable in installments and the exercisability of options may be accelerated by the Compensation Committee at any time. In general, unless otherwise permitted by the Compensation Committee, no option granted under the 2020 Plan is transferable by the optionee other than by will or by the laws of descent and distribution or pursuant to a domestic relations order, and options may be exercised during the optionee’s lifetime only by the optionee, or by the optionee’s legal representative or guardian in the case of the optionee’s incapacity.

Upon exercise of options, the option exercise price must be paid in full either in cash, by certified or bank check or other instrument acceptable to the Compensation Committee or by delivery (or attestation to the ownership) of shares that are beneficially owned by the optionee and that are not subject to risk of forfeiture so that such shares shall be purchased by the Company and the cash proceeds applied to pay-up the option exercise price. Subject to applicable law, the exercise price may also be delivered to the Company by a broker pursuant to irrevocable instructions to the broker from the optionee. In addition, non-qualified options may be exercised using a net exercise feature which reduces the number of shares issued to the optionee by the number of shares with a fair market value equal to the exercise price (provided that so much of the nominal value must be paid in cash, which may be paid by the Company or any subsidiary).

To qualify as incentive options, options must meet additional U.S. federal tax requirements, including a $100,000 limit on the value of shares subject to incentive options that first become exercisable by a participant in any one calendar year.

Share Appreciation Rights. The Compensation Committee may award share appreciation rights subject to such conditions and restrictions as the Compensation Committee may determine. Share appreciation rights entitle the recipient to ordinary shares or cash equal to the value of the appreciation in the share price over the exercise price. The exercise price is the fair market value of the ordinary shares on the date of grant. The term of a share appreciation right may not exceed ten years.

Restricted Shares. The Compensation Committee may award ordinary shares to participants subject to such conditions and restrictions as the Compensation Committee may determine (provided that so much of the nominal value must be paid in cash, which may be paid by the Company or any subsidiary). These conditions and restrictions may include the achievement of certain performance goals and/or continued employment with us through a specified restricted period. During the vesting period, restricted share awards may be credited with dividend equivalent rights (but dividend equivalents payable with respect to unvested restricted share awards shall not be paid unless and until such restricted shares vest).

Restricted Stock Units. The Compensation Committee may award restricted stock units to participants. Restricted stock units are ultimately payable in the form of ordinary shares or cash subject to such conditions and restrictions as the Compensation Committee may determine (provided that, if payable in shares, so much of the nominal value must be paid in cash, which may be paid by the Company or any subsidiary). These conditions and restrictions may include the achievement of certain performance goals and/or continued employment with the Company through a specified vesting period. In the Compensation Committee’s sole discretion, it may permit a participant to make an advance election to receive a portion of his or her future cash compensation otherwise due in the form of a restricted stock unit award, subject to the participant’s compliance with the procedures established by the Compensation Committee and requirements of Section 409A of the Code. During the deferral period, the deferred share awards may be credited with dividend equivalent rights.

Unrestricted Share Awards. The Compensation Committee may also grant ordinary shares which are free from any restrictions under the 2020 Plan. Unrestricted shares may be granted to any participant in recognition of past services or other valid consideration and may be issued in lieu of cash compensation due to such participant (provided that so much of the nominal value must be paid in cash, which may be paid by the Company or any subsidiary).

Dividend Equivalent Rights. The Compensation Committee may grant dividend equivalent rights to participants, which entitle the recipient to receive credits for dividends that would be paid if the recipient had

TABLE OF CONTENTS

held specified ordinary shares. Dividend equivalent rights granted as a component of another award (other than a share option or share appreciation right) may be paid only if the related award becomes vested. Dividend equivalent rights may be settled in cash, ordinary shares or a combination thereof, in a single installment or installments, as specified in the award.

Cash-Based Awards. The Compensation Committee may grant cash bonuses under the 2020 Plan to participants. The cash bonuses may be subject to the achievement of certain performance goals.

Change of Control Provisions. In the event of a “sale event,” as defined in the 2020 Plan, awards under 2020 Plan may be assumed, continued or substituted. In the event that awards are not assumed, continued or substituted, except as otherwise provided by the Compensation Committee in the award agreement, upon the effective time of the sale event, the Company may make or provide for payment, in cash or in kind, to participants holding options and share appreciation rights equal to the difference between the per share cash consideration and the exercise price of the options or share appreciation rights (provided that, in the case of an option or share appreciation right with an exercise price equal to or greater than the per share cash consideration, such option or share appreciation right shall be cancelled for no consideration). The Compensation Committee shall also have the option to make or provide for a payment, in cash or in kind, to grantees holding other awards in an amount equal to the per share cash consideration multiplied by the number of vested shares under such awards. All awards will terminate in connection with a sale event unless they are assumed by the successor entity.

Adjustments for Share Dividends, Share Splits, Etc. The 2020 Plan requires the Compensation Committee to make appropriate adjustments to the number of ordinary shares that are subject to the 2020 Plan, to certain limits in the 2020 Plan, and to any outstanding awards to reflect share dividends, share splits, extraordinary cash dividends and similar events.

Tax Withholding. Participants in the 2020 Plan are responsible for the payment of any U.S. federal, state or local taxes that the Company is required by law to withhold upon the exercise of options or share appreciation rights or vesting of other awards. The Compensation Committee may require that tax withholding obligations satisfied by withholding ordinary shares to be issued pursuant to exercise or vesting. The Compensation Committee may also require the Company’s tax withholding obligation to be satisfied, in whole or in part, by an arrangement whereby a certain number of shares issued pursuant to any award are immediately sold and proceeds from such sale are remitted to the Company in an amount that would satisfy the withholding amount due.

Amendments and Termination. The Board may at any time amend or discontinue the 2020 Plan and the Compensation Committee may at any time amend or cancel any outstanding award for the purpose of satisfying changes in the law or for any other lawful purpose. However, no such action may adversely affect any rights under any outstanding award without the holder’s consent. To the extent required under the rules of Nasdaq, any amendments that materially change the terms of the 2020 Plan will be subject to approval by our shareholders. Amendments shall also be subject to approval by our shareholders if and to the extent determined by the Compensation Committee to be required by the Code to preserve the qualified status of incentive options.

Effective Date of Plan. The 2020 Plan was approved by our Board on April 13, 2020 and our shareholders on August 5, 2020. On April 17, 2023, the Board approved the amendment to the 2020 Plan, subject to shareholder approval. Awards of incentive options may be granted under the 2020 Plan until April 13, 2030. No other awards may be granted under the 2020 Plan after the date that is ten years from the date of shareholder approval.

New Plan Benefits

All awards to executive officers in future periods are made at the discretion of the Compensation Committee and our board of directors. Therefore, the benefits and amounts that will be received or allocated under the 2020 Plan to such persons are not determinable at this time.

Tax Aspects Under the Code

The following is a summary of the principal U.S. federal income tax consequences of certain transactions under the 2020 Plan. It does not describe all U.S. federal tax consequences under the 2020 Plan, nor does it describe state or local tax consequences.

Incentive Options. No taxable income is generally realized by the optionee upon the grant or exercise of an incentive option. If ordinary shares issued to an optionee pursuant to the exercise of an incentive option are sold or transferred after two years from the date of grant and after one year from the date of exercise, then (i) upon sale of such shares, any amount realized in excess of the option price (the amount paid for the shares) will be taxed to the optionee as a long-term capital gain, and any loss sustained will be a long-term capital loss, and (ii) the Company will not be entitled to any deduction for U.S. federal income tax purposes. The exercise of an incentive option will give rise to an item of tax preference that may result in alternative minimum tax liability for the optionee.

If ordinary shares acquired upon the exercise of an incentive option are disposed of prior to the expiration of the two-year and one-year holding periods described above (a “disqualifying disposition”), generally (i) the optionee will realize ordinary income in the year of disposition in an amount equal to the excess (if any) of the fair market value of the ordinary shares at exercise (or, if less, the amount realized on a sale of such shares) over the option price thereof, and (ii) we will be entitled to deduct such amount. Special rules will apply where all or a portion of the exercise price of the incentive option is paid by tendering ordinary shares.

If an incentive option is exercised at a time when it no longer qualifies for the tax treatment described above, the option is treated as a non-qualified option. Generally, an incentive option will not be eligible for the tax treatment described above if it is exercised more than three months following termination of employment (or one year in the case of termination of employment by reason of disability). In the case of termination of employment by reason of death, the three-month rule does not apply.

Non-Qualified Options. No income is realized by the optionee at the time a non-qualified option is granted. Generally (i) at exercise, ordinary income is realized by the optionee in an amount equal to the difference between the option price and the fair market value of the shares on the date of exercise, and we receive a tax deduction for the same amount, and (ii) at disposition, appreciation or depreciation after the date of exercise is treated as either short-term or long-term capital gain or loss depending on how long the shares have been held. Special rules will apply where all or a portion of the exercise price of the non-qualified option

TABLE OF CONTENTS

is paid by tendering ordinary shares. Upon exercise, the optionee will also be subject to Social Security taxes on the excess of the fair market value over the exercise price of the option.

Other Awards. The Company generally will be entitled to a tax deduction in connection with other awards under the 2020 Plan in an amount equal to the ordinary income realized by the participant at the time the participant recognizes such income. Participants typically are subject to income tax and recognize such tax at the time that an award is exercised, vests or becomes non-forfeitable, unless the award provides for a further deferral.

Parachute Payments. The vesting of any portion of an award that is accelerated due to the occurrence of a change in control (such as a sale event) may cause a portion of the payments with respect to such accelerated awards to be treated as “parachute payments” as defined in the Code. Any such parachute payments may be non-deductible to the Company, in whole or in part, and may subject the recipient to a non-deductible 20% U.S. federal excise tax on all or a portion of such payment (in addition to other taxes ordinarily payable).

Limitation on Deductions. Under Section 162(m) of the Code, the Company’s deduction for awards under the 2020 Plan may be limited to the extent that any “covered employee” (as defined in Section 162(m) of the Code) receives compensation in excess of $1 million a year.

The resolution in respect of this Proposal 3 is an ordinary resolution. The text of the resolution in respect of Proposal 3 is as follows:

“IT IS RESOLVED, that the Company’s shareholders approve an amendment to the Avadel Pharmaceuticals plc 2020 Omnibus Incentive Plan as disclosed in this proxy statement.”

Required Vote and Board Recommendation

THE BOARD RECOMMENDS THAT YOU VOTE “FOR” THE APPROVAL OF THE AMENDMENT TO THE AVADEL PHARMACEUTICALS PLC 2020 OMNIBUS INCENTIVE PLAN.

CERTAIN MATTERS RELATING TO PROXY MATERIALS AND ANNUAL REPORTS

Solicitation of Proxies

The cost of the solicitation of proxies on behalf of Avadel Pharmaceuticals plc will be borne by the Company. In addition, the Company’s directors, officers and other employees may, without additional compensation except reimbursement for any actual expenses, solicit proxies by mail, in person or by telecommunication. We may retain a third party to solicit proxies, which costs would also be borne by the Company. We will reimburse brokers, fiduciaries, custodians and other nominees for out-of-pocket expenses incurred in sending Company proxy materials to, and obtaining instructions relating to such materials from, beneficial owners.

Shareholder Proposals for 2024 Meeting

Shareholders who wish to present a proposal to be included in our Proxy Statement for our 2024 annual general meeting of shareholders (the “2024 Meeting”) must submit the proposal to us no later than December 29, 2023 and must otherwise comply with the requirements of Rule 14a-8 of the Exchange Act and our constitution. The Board, at the recommendation of the Nominating and Corporate Governance Committee, has established the same date (December 29, 2023) for shareholders to submit nominees for directors for inclusion in our Proxy Statement for our 2024 Meeting, and December 29, 2023 as the date for Shareholders to present other business at our Meeting of Shareholders without inclusion in our Proxy Statement for such meeting. All such proposals must be sent in writing to our Company Secretary at Ten Earlsfort Terrace, Dublin 2, D02 T380 Ireland.

All proposals submitted by holders of ordinary shares are reviewed by the Corporate Governance Committee or the Nominating Committee and by the Board.

An ADS holder does not have a right to present proposals for shareholder approval at the Meeting. To submit proposals at the Meeting, an ADS holder must convert the ADSs into ordinary shares by contacting the Depositary and complying with the rules described above.

Eligibility to Submit a Proposal: Under Rule 14a-8 promulgated under the Securities Exchange Act of 1934, in order to be eligible to submit a proposal, you must have continuously held at least $2,000 in market value, or 1%, of the Company’s securities entitled to be voted on the proposal at the meeting for at least one year by the date you submit the proposal. You must continue to hold those securities through the date of the meeting.

Shareholder Nomination Procedures. In addition, to comply with the universal proxy rules (once effective), stockholders who intend to solicit proxies in support of director nominees other than the Company’s nominees must provide notice that sets forth the information required by Rule 14a-19 under the Securities Exchange Act of 1934 no later than June 2, 2024.

Irish Disclosure of Shareholder Interests

Under the Companies Act, our shareholders must notify us if, as a result of a transaction, the shareholder will become interested in 3% or more of our shares; or if as a result of a transaction a shareholder who was interested in more than 3% of our shares ceases to be so interested. Where a shareholder is interested in more than 3% of our shares, the shareholder must notify us of any alteration of his or her interest that brings his or her total holding through the nearest whole percentage number, whether an increase or a reduction. The relevant percentage figure is calculated by reference to the aggregate nominal value of the shares in which the shareholder is interested as a proportion of the entire nominal value of our issued share capital (or any such class of share capital in issue), and disclosable interests in our shares include any interests in our shares of any kind whatsoever. Where the percentage level of the shareholder’s interest does not amount to a whole percentage this figure may be rounded down to the next whole number. We must be notified within five business days of the transaction or alteration of the shareholder’s interests that gave rise to the notification requirement. If a shareholder fails to comply with these notification requirements, the shareholder’s rights in respect of any our ordinary shares it holds will not be enforceable, either directly or indirectly. However, such person may apply to the court to have the rights attaching to such shares reinstated.

Annex A

AMENDMENT
TO THE
AVADEL PHARMACEUTICALS PLC
2020 OMNIBUS INCENTIVE COMPENSATION PLAN

WHEREAS, Avadel Pharmaceuticals plc (the “Company”) maintains the Avadel Pharmaceuticals plc 2020 Omnibus Incentive Compensation Plan (the “Plan”), which was previously adopted by the Board of Directors on April 13, 2020 and approved by the shareholders of the Company on August 5, 2020;

WHEREAS, the Board of Directors of the Company believes that the number of ordinary shares of the Company (“Ordinary Shares”) remaining available for issuance under the Plan has become insufficient for the Company’s anticipated future needs under the Plan;

WHEREAS, Section 16 of the Plan provides that the Board of Directors of the Company may amend the Plan at any time, subject to certain conditions set forth therein; and

WHEREAS, the Board of Directors of the Company has determined that it is in the best interests of the Company to amend the Plan, subject to shareholder approval, to increase both the aggregate number of Ordinary Shares available for issuance under the Plan, and the number of shares that may be issued in the form of Incentive Stock Options (as defined in the Plan) from 6,000,000 shares to 12,500,000 shares.

NOW, THEREFORE:

1. Increase in Shares. Section 3(a) of the Plan is hereby amended by deleting it in its entirety and replacing it with the following:

“The maximum number of Shares reserved and available for issuance under the Plan shall be 12,500,000 shares, subject to adjustment as provided in this Section 3. For purposes of this limitation, the Shares underlying any awards under the Plan and under the Company’s 2017 Omnibus Incentive Compensation Plan that are forfeited, canceled or otherwise terminated (other than by exercise) shall be added back to the Shares available for issuance under the Plan and, to the extent permitted under Section 422 of the Code and the regulations promulgated thereunder, the Shares that may be issued as Incentive Stock Options. Notwithstanding the foregoing, the following shares shall not be added to the shares authorized for grant under the Plan: (i) Shares tendered or held back upon exercise of an Option or settlement of an Award to cover the exercise price or tax withholding, and (ii) Shares subject to a Share Appreciation Right that are not issued in connection with the share settlement of the Share Appreciation Right upon exercise thereof. In the event the Company repurchases Shares on the open market, such Shares shall not be added to the Shares available for issuance under the Plan. Subject to such overall limitations, Shares may be issued up to such maximum number pursuant to any type or types of Award; provided, however, that no more than 12,500,000 Shares may be issued in the form of Incentive Stock Options. The Shares available for issuance under the Plan may be authorized but unissued Shares or Shares reacquired by the Company.”

2. Effective Date of Amendment. This Amendment to the Plan shall become effective upon the date that it is approved by the Company’s shareholders in accordance with applicable laws and regulations.

3. Other Provisions. Except as set forth above, all other provisions of the Plan shall remain unchanged.

IN WITNESS WHEREOF, this Amendment to the Plan has been adopted by the Board of Directors of the Company this 17th day of April, 2023 and approved by the Company’s shareholders on [ ].
