IMMUNOMEDICS, INC. AND SUBSIDIARIES

NOTES TO UNAUDITED CONDENSED CONSOLIDATED

FINANCIAL STATEMENTS

Reference is made to the Transition Report on Form 10-K, of Immunomedics, Inc., a Delaware corporation (“Immunomedics,” the “Company,” “we,” “our” or “us”), for the six months ended December 31, 2018, which contains our audited consolidated financial statements and the notes thereto.

1.    Business Overview, Basis of Presentation and Recent Accounting Pronouncements

Business Overview

Immunomedics, Inc., a Delaware corporation, together with its subsidiaries (collectively "we," "our," "us," "Immunomedics", or the "Company"), is a clinical-stage biopharmaceutical company that develops monoclonal antibody-based products for the targeted treatment of cancer. Immunomedics manages its operations as one line of business of researching, developing, manufacturing and marketing biopharmaceutical products, particularly antibody-based products for patients with difficult to treat solid tumor and blood cancers. The Company currently reports as a single industry segment with substantially all business conducted in the United States. Immunomedics conducts its research activities in the United States and runs its development studies in the United States and selected European countries. Our corporate objective is to become a fully-integrated biopharmaceutical company and a leader in the field of antibody-drug conjugates (“ADCs”). To that end, our immediate priority is to commercialize our most advanced ADC product candidate, sacituzumab govitecan ("IMMU-132"), beginning in the United States, with metastatic triple-negative breast cancer (“mTNBC”) as the first indication. On May 21, 2018, we submitted a Biologics License Application (“BLA”) to the United States Food and Drug Administration ("FDA") for sacituzumab govitecan for the treatment of patients with mTNBC who have received at least two prior therapies for metastatic disease. On July 18, 2018, we received notification from the FDA that the BLA was accepted for filing and the original application was granted Priority Review with a Prescription Drug User Fee Act ("PDUFA") target action date of January 18, 2019. On January 17, 2019, we received a Complete Response Letter ("CRL") from the FDA for the BLA. We subsequently met with the FDA on May 2, 2019 to review the FDA’s findings and discussed our BLA resubmission. Since then, we have developed a detailed plan to address the chemistry, manufacturing, and control (“CMC”) matters raised in the CRL and in our pre-approval inspection. We held another meeting with the FDA on September 27, 2019 to update the FDA on our progress in addressing these matters and to receive feedback from the FDA on our approach. We have dedicated, and continue to commit, significant resources to address the CMC matters identified by the FDA, while, in parallel, preparing our manufacturing facility to be ready for re-inspection by the FDA for acknowledgment of receipt of the submission.

Basis of Presentation

The accompanying unaudited condensed consolidated financial statements of Immunomedics, which incorporates our foreign subsidiary, Immunomedics GmbH in Rödermark, Germany, have been prepared in accordance with United States generally accepted accounting principles (“GAAP”), for interim financial information and the instructions to the Quarterly Report on Form 10‑Q and Regulation S‑X. Accordingly, the statements do not include all of the information and footnotes required by GAAP for complete annual financial statements. With respect to the financial information for the interim periods included in this Quarterly Report on Form 10-Q, which is unaudited, management believes that all adjustments (consisting of normal recurring accruals), considered necessary for a fair presentation of the results for such interim periods have been included. Operating results for the three and nine-month periods ended September 30, 2019, are not necessarily indicative of the results that may be expected for the full calendar year ending December 31, 2019, or any other period. The preparation of the condensed consolidated financial statements requires management to make estimates and assumptions that affect reported amounts and disclosures. Actual results could differ from those estimates.

Our significant accounting policies are described in Note 2 of Notes to Consolidated Financial Statements included in our 2018 Transition Report on Form 10-K. Such significant accounting policies are applicable for periods prior to the adoption of the following new accounting standards.

Recent Accounting Pronouncements

Accounting Pronouncements adopted during the year:

The Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2019-01, “Leases Topic 842,” requiring entities to recognize assets and liabilities on the balance sheet for all leases, with certain exceptions. Topic 842 allows for a modified retrospective application and is effective as of the first quarter of 2019. Entities are allowed to apply the new guidance using a modified retrospective approach at the beginning of the year in which new lease standard is adopted, rather than to the earliest comparative period presented in their financial statements. The modified retrospective approach includes a number of optional practical expedients that entities may elect to apply. We elected the modified retrospective approach under the new guidance and elected the available practical expedients on adoption. Upon adoption, we recognized additional operating lease liabilities of $8.4 million with a corresponding right-of-use assets of $8.4 million based on the present value of the remaining lease payments under existing operating leases. As of December 31, 2018, we had $2.1 million in deferred charges related to our real estate leases that were recorded against the lease liability asset as part of the transition, resulting in $10.5 million included in other long-term liabilities on our condensed consolidated balance sheet. In addition, the new guidance resulted in additional lease-related disclosures in the footnotes to our condensed consolidated financial statements. Our leasing portfolio is comprised entirely of operating leases, and we do not recognize right-of-use assets or related lease liabilities with a lease term of twelve months or less on our condensed consolidated balance sheet. Adoption of Topic 842 has required changes to our business processes and controls to comply with the provisions of the standard. Refer to Note 11 "Commitments and Contingencies" for additional information.

In June 2018, the FASB issued ASU 2018-07, "Compensation-Stock Compensation," to improve the usefulness of information provided to users of financial statements while reducing cost and complexity in financial reporting and provide guidance aligning the measurement and classification for share-based payments to nonemployees with the guidance for share-based payments to employees. Under the guidance, the measurement of equity-classified nonemployee awards will be fixed at the grant date. This standard is effective for fiscal years beginning after December 15, 2018, and interim periods within those annual periods. Early adoption is permitted, but no earlier than an entity's adoption date of ASU 2014-09, “Revenue from Contracts with Customers (Topic 606).” We adopted ASU 2018-07 during the first quarter of 2019 and the adoption did not have a material impact to our condensed consolidated financial statements.

Accounting Pronouncements yet to be adopted:

In November 2018, the FASB issued ASU 2018-18, "Collaborative Arrangements (Topic 808): Clarifying the Interaction between Topic 808 and Topic 606,"    to clarify when ASC 606 should be used for collaborative arrangements when the counterparty is a customer. The guidance precludes an entity from presenting consideration from a transaction in a collaborative arrangement as revenue from contracts with customers if the counterparty is not a customer for that transaction. The guidance is effective for public business entities in fiscal years beginning after December 15, 2019, and interim periods therein. Early adoption is permitted to entities that have adopted ASC 606. We are currently assessing the impact of ASU 2018-18.

In August 2018, the FASB issued ASU 2018-13, "Fair Value measurement (Topic 820): Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement," to no longer require public companies to disclose transfers between Level 1 and Level 2 of the fair value hierarchy, and to require disclosure about the range and weighted average used to develop significant unobservable inputs for Level 3 fair value measurements. The guidance is effective for fiscal years beginning after December 15, 2019, and for interim periods within those fiscal years. Entities are permitted to early adopt either the entire standard or only the provisions that eliminate or modify the requirements. We are currently assessing the impact of ASU 2018-13.

2.          Revenue Recognition

Pursuant to Topic 606, we recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. To achieve this core principle, Topic 606 includes provisions within a five step model that includes i) identifying the contract with a customer, ii) identifying the performance obligations in the contract, iii) determining the transaction price, iv) allocating the transaction price to the performance obligations, and v) recognizing revenue when, or as, an entity satisfies a performance obligation.

At contract inception, we assess the goods or services promised within each contract and assess whether each promised good or service is distinct and determine those that are performance obligations. We then recognize as revenue the amount of the transaction price that is allocated to the respective performance obligation when the performance obligation is satisfied.

Everest Medicines II Limited:

On April 29, 2019, the Company entered into a license agreement (the “License Agreement”) with Everest Medicines II Limited, a China limited company (“Everest”). Pursuant to the License Agreement, the Company granted Everest an exclusive license to develop and commercialize sacituzumab govitecan in the People’s Republic of China, Taiwan, Hong Kong, Macao, Indonesia, Philippines, Vietnam, Thailand, South Korea, Malaysia, Singapore and Mongolia (the "Territory"). In consideration for entering into the License Agreement, Everest made a one-time, non-refundable upfront payment to the Company in the aggregate amount of $65.0 million which is recorded as deferred revenue. The License Agreement contains a development milestone payment of $60.0 million based upon the Company’s achievement of FDA approval for sacituzumab govitecan in mTNBC. The License Agreement also contains additional development milestone payments in a total amount of up to $180.0 million based upon the achievement of certain other development milestones. In addition, the License Agreement contains sales milestone payments in a total amount of up to $530.0 million based upon the achievement of certain sales milestones. Everest will make royalty payments to the Company based upon percentages of net sales of sacituzumab govitecan, ranging from 14% to 20%.

The Company assessed the arrangement in accordance with ASC 606 and concluded that the contract counterparty, Everest, is a customer based on the arrangement structure. The Company identified two material promises to deliver under the contract: (1) grant of license and the (2) clinical and commercial supply of the product. However, given the nature of the manufacturing of the product the license is not considered to be distinct from the clinical and commercial supply promise. The Company therefore concluded that there is one combined performance obligation.

The Company initially deferred and will recognize the $65.0 million over the performance obligation period of the combined performance obligation. As it relates to the upfront consideration, the $65.0 million is recorded as deferred revenue and will be recognized over the term of the of the contract performance obligation period, which the Company has concluded to be 15 years after initial sale of the product in the territory. As concluded above, the Company has a combined performance obligation, which includes delivering the license and clinical and commercial supply to Everest. As such, because the clinical and commercial supply obligation occur throughout the period of the License Agreement, the $65.0 million fixed consideration is recognized over the period in which commercial and clinical supply of product is delivered (over-time).

The future potential milestone payments are excluded from the transaction price, as the achievement of the milestone events require considerable judgment in determining whether it is probable of being achieved, and that a significant revenue reversal would not occur. As such, all milestone payments are fully constrained. The Company will reevaluate the transaction price at the end of each reporting period and as uncertain events are resolved or other changes in circumstances occur, and, if necessary, adjust its estimate of the transaction price.

Janssen Biotech Inc.:

On April 5, 2019, the Company entered into a promotion agreement (the “Promotion Agreement”) with Janssen Biotech Inc., ("Janssen") pursuant to which the Company will provide non-exclusive product detailing services to Janssen for erdafitinib (the “Product”). Pursuant to the Promotion Agreement, the Company will provide a dedicated sales team to market the Product, upon approval by the FDA, to oncologists and other targeted health care providers in the United States. Under the terms of the Promotion Agreement, Janssen maintains ownership of the New Drug Application for the Product as well as legal, regulatory, distribution, commercialization and manufacturing responsibilities for the Product, while the Company will provide product detailing services to Janssen.  Following the achievement of certain sales targets in 2019 and 2020, Janssen will pay the Company (a) a service fee equal to a percentage in the low double digits of the portion of Cumulative Net Sales (as defined in the Promotion Agreement) in excess of a baseline amount during each of 2019 and 2020, and (b) potential milestone payments of up to $15.0 million when Cumulative Net Sales exceed certain thresholds during each of 2019 and 2020. On April 12, 2019, the Company

10

was informed that the FDA granted accelerated approval to Janssen's Balversa (erdafitinib) for the treatment of adult patients with locally advanced or metastatic urothelial carcinoma that has a type of susceptible genetic alteration known as FGFR3 or FGFR2, and that has progressed during or following prior platinum-containing chemotherapy. During the three and nine months ended September 30, 2019, no revenues were recorded relating to the Promotion Agreement.

4.    Debt

Liability Related to Sale of Future Royalties:

On January 7, 2018, the Company entered into a funding agreement with RPI Finance Trust, a Delaware statutory trust ("RPI"), under which we sold a portion of our right to receive royalties on potential net sales of the ADC sacituzumab govitecan, in exchange for $175.0 million in cash. Concurrently, we entered into a common stock purchase agreement with RPI through which RPI purchased 4.4 million shares of the Company's common stock for $75.0 million (the "Financing").

The Company concluded that there were two units of accounting in the transaction: (1) the liability related to the sale of future royalties (the "Liability") and (2) the "Financing". We allocated the consideration of $250.0 million on a relative fair value basis to the Liability for $182.2 million and the common stock for $67.8 million. We continue to accrete the Liability related to the sale of future royalties using the effective interest method with an annual interest rate of approximately 16% over a period of 20 years. As of September 30, 2019 and December 31, 2018, we determined the fair value at $251.3 million and $221.3 million, respectively. During the three months ended September 30, 2019 and 2018, the Company recognized approximately $9.6 million and $9.8 million in interest expense, respectively. During the nine months ended September 30, 2019 and 2018, the Company recognized approximately $30.0 million and $29.6 million in interest expense, respectively.

Convertible Senior Notes:

In February 2015, the Company issued $100.0 million of Convertible Senior Notes (the "Convertible Senior Notes") (net proceeds of approximately $96.3 million after deducting the initial purchasers’ fees and offering expenses) in a private offering exempt from registration under the Securities Act of 1933, as amended (the “Securities Act”), in reliance upon Rule 144A under the Securities Act. The Convertible Senior Notes will mature on February 15, 2020, unless earlier purchased or converted. The debt issuance costs of approximately $3.7 million, primarily consisting of underwriting, legal and other professional fees, are amortized over the term of the Convertible Senior Notes. The Convertible Senior Notes are senior unsecured obligations of the Company. Interest at 4.75% is payable semiannually on February 15 and August 15 of each year. The effective interest rate on the Convertible Senior Notes was 5.48% for the period from the date of issuance through September 30, 2019. The balance of the outstanding Convertible Senior Notes was $7.1 million convertible into 1.4 million shares of common stock at September 30, 2019, and December 31, 2018.

If the Company undergoes a fundamental change (as defined in the indenture governing the Convertible Senior Notes), holders may require Immunomedics to purchase for cash all or part of the Convertible Senior Notes at a purchase price equal to 100% of the principal amount of the Convertible Senior Notes to be purchased, plus accrued and unpaid interest, if any, to, but excluding, the fundamental change purchase date, subject to certain exceptions. In addition, if certain make-whole fundamental changes (as defined in the indenture governing the Convertible Senior Notes) occur, Immunomedics will, in certain circumstances, increase the conversion rate for any Convertible Note converted in connection with such make-whole fundamental change.

Total interest expense for the Convertible Senior Notes for the three months ended September 30, 2019 and 2018 was $0.1 million and $0.2 million, respectively. For the nine months ended September 30, 2019 and 2018, interest expense was $0.3 million and $0.7 million, respectively. Included in interest expense was an immaterial amount of amortization of debt issuance costs for the three and nine months ended September 30, 2019 and 2018.

9.        Related Party Transactions

On January 8, 2018, Morris Rosenberg joined the Company as Chief Technology Officer and became a full-time employee. Between May 5, 2017 and January 7, 2018, Mr. Rosenberg was engaged by the Company as an independent consultant pursuant to a consulting agreement between the Company and Mr. Rosenberg’s consulting company, M Rosenberg BioPharma Consulting LLC. The Company paid M Rosenberg BioPharma Consulting LLC $0.6 million during this time and Morris Rosenberg was also granted stock options to purchase 45,000 shares of the Company's common stock pursuant to the Immunomedics, Inc. 2014 Long-Term Incentive Plan. From January 8, 2018 through September 30, 2018, the Company paid M Rosenberg BioPharma $0.8 million for services agreed upon prior to Mr. Rosenberg becoming a full-time employee. As part of his employment contract, 50% of the 45,000 shares granted to Mr. Rosenberg as a consultant were forfeited, and the remaining 50% continue to vest. Mr. Rosenberg received 104,389 stock options and was permitted to continue to provide certain limited outside consulting services through M Rosenberg BioPharma Consulting LLC based on certain restrictions outlined in the contract.

10.    Collaboration Agreements

AstraZeneca/MedImmune

In June 2018, the Company entered into a clinical collaboration with AstraZeneca PLC ("AstraZeneca") and its global biologics research and development arm, MedImmune, to evaluate in Phase 1/2 studies the safety and efficacy of combining AstraZeneca’s Imfinzi^® (durvalumab), a human monoclonal antibody directed against programmed cell death ligand 1 ("PD-L1"), with sacituzumab govitecan as a treatment of patients with triple-negative breast cancer (“TNBC”) and urothelial cancer ("UC"), which was broadened in October 2018 to include second-line metastatic non-small cell lung cancer ("NSCLC").

Part one of the two-part Phase 1/2 studies will be co-funded by the two companies. Immunomedics will supply the study drug and AstraZeneca will utilize its existing clinical trial infrastructure to accelerate the enrollment of the sacituzumab govitecan and durvalumab combination. The trial design allows for rapid transition into randomized Phase 2 studies should the first part of these studies show promising data and the companies agree to proceed based on efficacy and safety results obtained.

The collaboration terminates thirty days following the expiration of the study periods end-date. Either party may terminate the collaboration earlier by providing thirty days' written notice.

GBG Forschungs GmbH

In September 2019, the Company entered into a clinical collaboration with GBG Forschungs-GmbH ("GBG"), Neu-Isenburg, Germany, to develop sacituzumab govitecan as a treatment for newly-diagnosed breast cancer patients who do not achieve a pathological complete response ("pCR") following standard neoadjuvant therapy.

The multinational, post-neoadjuvant Phase 3 SASCIA study developed by GBG will be conducted under the sponsorship of GBG. Approximately 1,200 high-risk patients with newly-diagnosed HER2-negative breast cancer not achieving a pCR following standard neoadjuvant therapy will be randomized to receive either sacituzumab govitecan or treatment of physician’s choice. Primary endpoint is invasive DFS with overall survival, patient reported outcome/quality of life, circulating tumor DNA clearance, and safety serving as secondary endpoints.

Under the terms of the agreement, GBG is eligible to receive up to €33.0 million in potential clinical and regulatory milestone payments over a span of approximately six years, of which €0.5 million to be paid at signing which is included in accrued expenses as of September 30, 2019. The collaboration terminates following the completion of the study or until either party terminates the collaboration earlier by providing thirty days' written notice.

11.    Commitments and Contingencies

a. Legal Matters

Stockholder Complaints:

Class Action Stockholder Federal Securities Cases

Two purported class action cases were filed in the United States District Court for the District of New Jersey; namely, Fergus v. Immunomedics, Inc., et al., filed June 9, 2016; and Becker v. Immunomedics, Inc., et al., filed June 10, 2016. These cases arise from the same alleged facts and circumstances and seek class certification on behalf of purchasers of our common stock between April 20, 2016 and June 2, 2016 (with respect to the Fergus matter) and between April 20, 2016 and June 3, 2016 (with respect to the Becker matter). These cases concern the Company’s statements in press releases, investor conference calls, and filings with the U.S. Securities and Exchange Commission (the "SEC") beginning in April 2016 that the Company would present updated information regarding its IMMU-132 breast cancer drug at the 2016 American Society of Clinical Oncology (“ASCO”) conference in Chicago, Illinois. The complaints allege that these statements were false and misleading in light of June 2, 2016 reports that ASCO had canceled the presentation because it contained previously reported information. The complaints further allege that these statements resulted in artificially inflated prices for our common stock, and that the Company and certain of its officers are thus liable under Sections 10(b) and 20(a) of the Securities Exchange Act of 1934, as amended (the "Exchange Act"). An order of voluntary dismissal without prejudice was entered on November 10, 2016 in the Becker matter. An order granting motion to consolidate cases, appoint lead plaintiff, and approve lead and liaison counsel was entered on February 7, 2017 in the Fergus matter. A consolidated complaint was filed on October 4, 2017. The Company filed a motion to dismiss the consolidated complaint on January 26, 2018. On March 31, 2019, the court granted the Company's motion to dismiss, without prejudice, and

16

left plaintiffs with the ability to file an amended complaint within thirty (30) days. Counsel for the Company has consented to an extension of time for plaintiffs to file the proposed amended complaint for an additional thirty (30) days. On May 30, 2019, plaintiffs filed an amended complaint alleging many of the same allegations that were set forth in the previously filed complaints, and the Company has filed a motion to dismiss.

A third purported class action case was filed in the United States District Court for the District of New Jersey; namely, Odeh v. Immunomedics, Inc., et al., filed December 27, 2018. The complaint in this action alleges that the Company failed to disclose the results of observations made by the FDA during an inspection of the Company’s manufacturing facility in Morris Plains, New Jersey in August 2018. The complaint alleges that Immunomedics misled investors by failing to disclose the Form 483 inspection report issued by the FDA which set forth the observations of the FDA inspector during the inspection. Such observations purportedly included, inter alia, manipulated bioburden samples, misrepresentation of an integrity test procedure in the batch record, and backdating of batch records. The complaint further alleges that the Company’s failure to disclose the Form 483 resulted in an artificially inflated price for our common stock, and that the Company and certain of its officers are thus liable under Sections 10(b) and 20(a) of the Exchange Act.

On February 8, 2019, a purported class action case was filed in the United States District Court for the District of New Jersey; namely, Choi v. Immunomedics, Inc., et al. The complaint asserts violations of the federal securities laws based on claims that the Company violated the federal securities laws by making alleged misstatements in various press releases and securities filings from February 8, 2018 to November 7, 2018 and by failing to disclose the substance of its interactions with the FDA in connection with the Company's submission of its BLA for sacituzumab govitecan. 

Motions for the appointment of a lead plaintiff and lead counsel and to consolidate the Odeh and Choi actions were granted on September 10, 2019. Pursuant to a scheduling order entered by the court on October 7, 2019, the plaintiffs must file an amended complaint by November 18, 2019.

On April 8, 2019, a putative stockholder of the Company filed a derivative action purportedly on behalf of the Company and against the Company’s board of directors and certain Company current and former officers, in the Superior Court of New Jersey, Law Division (Morris County); namely, Crow v. Aghazadeh, et al. The Crow complaint alleges that the individual defendants breached their fiduciary duties and committed other violations of law based on the same core allegations in the Odeh and Choi actions. The Crow complaint was served on the Company and other defendants on July 18, 2019. On August 13, 2019, the parties submitted to the court a stipulation and proposed order to stay the action until either the entry of an order denying all motions to dismiss the now-consolidated federal actions or the entry of an order dismissing the federal actions with prejudice. That stipulation is currently pending court approval.

Stockholder Claim in the Court of Chancery of the State of Delaware

On February 13, 2017, venBio commenced an action captioned venBio Select Advisor LLC v. Goldenberg, et al., C.A. (Del. Ch.) (the “venBio Action”), alleging that Company’s Board breached their fiduciary duties when the Board (i) amended the Company’s Amended and Restated By-laws (the “By-Laws”) to call for a plurality voting regime for the election of directors instead of majority voting, and providing for mandatory advancement of attorneys’ fees and costs for the Company’s directors and officers, (ii) rescheduled the Company’s 2016 Annual Meeting of Stockholders (the “2016 Annual Meeting”) from December 14, 2016 to February 16, 2017, and then again to March 3, 2017, and (iii) agreed to the proposed Licensing Transaction with Seattle Genetics. venBio also named Seattle Genetics as a defendant and sought an injunction preventing the Company from closing the licensing transaction with Seattle Genetics. On March 6, 2017, venBio amended its complaint, adding further allegations. The Court of Chancery entered a temporary restraining order on March 9, 2017, enjoining the closing of the Licensing Transaction. venBio amended its complaint a second time on April 19, 2017, this time adding Greenhill & Co. Inc. and Greenhill & Co. LLC (together “Greenhill”), the Company’s financial advisor on the Licensing Transaction, as an additional defendant. On May 3, 2017, venBio and the Company and individual defendants Dr. Goldenberg, Ms. Sullivan and Mr. Brian A. Markison, a director of the Company (collectively, the “Individual Defendants”) entered into the Initial Term Sheet. On June 8, 2017, venBio the Company and Greenhill entered into the Greenhill Term Sheet. On February 9, 2018, the Court of Chancery approved the Settlement, and entered an order and partial judgment releasing all claims that were asserted by venBio against the Individual Defendants and Greenhill in the venBio Action and awarding venBio fees and expenses. On May 24, 2018 the remaining parties to the venBio Action participated in a mediation of the claims against Geoff Cox, Robert Forrester, Bob Oliver, and Jason Aryeh (the "Remaining Defendants"). The mediation was unsuccessful. The Remaining Defendants filed submitted motions to dismiss the claims against them in the venBio Action. On March 18, 2019, venBio amended its complaint, adding further allegations. The Remaining Defendants filed a motion to dismiss the claims against them on May 1, 2019. The Court of Chancery has scheduled oral arguments for the motion to dismiss on November 13, 2019.

Insurance Coverage Arbitration:

The Company has initiated an arbitration with two of its management liability insurers: Starr Indemnity & Liability Company (“Starr”), and Liberty Insurance Underwriters Inc. (“Liberty”) (collectively, “Insurers”).  The arbitration arises from the 2015 Insurers’ refusal to cover $3,402,980 in attorneys’ fees and expenses paid to venBio pursuant to a December 1, 2017, settlement agreement between venBio, the Company, Dr. Goldenberg, Ms. Sullivan, Mr. Markison, and Greenhill to partially settle the venBio Action and fully settle the Federal Action and the Delaware Section 225 Action (the “venBio Fee Award”).  

The Insurers argue that the venBio Fee Award does not satisfy their policies’ definitions of covered “loss” because the policies only cover defense costs incurred by the Company.  The Company counters that the venBio Fee Award is a covered settlement, not a claim for defense costs.  Insurers also argue that they have no obligation to pay any defense costs or settlement incurred in the Federal Action or 225 Action because Immunomedics initiated those lawsuits.  The Company’s position is that the Federal Action and 225 Action were defensive in nature and therefore covered because they were initiated to further the defense of the venBio Action.  Additionally, Insurers argue the venBio Fee Award is not covered because the Company was required to obtain Insurers’ consent to enter into a binding term sheet in the venBio Action and to agree to pay the venBio Fee Award and that the Company failed to do so.  The Company takes the position that Insurers at all times were aware of the developments in the venBio Action, that they sought consent to enter into the settlement, and that Insurers cannot show they were prejudiced by an any alleged failure to obtain Insurers’ consent.

Liberty also contends that the Company’s insurance claim is not covered by Liberty’s 2015-16 insurance policy and should be covered by another company’s policy in a later policy period. The Company takes the position that the policies treat the venBio Action as a related claim to the Fergus v. Immunomedics class action stockholder federal securities case, which was filed in 2016 and that because of the similar allegation in the venBio Action and Fergus, the policies deem the venBio Action claim to be made at the same time as Fergus and covered by the 2015-16 policies. In the arbitration, Starr contends it will have the benefit of any finding that the claim is covered in a later policy period, even though Starr had agreed with the Company’s position prior to the arbitration.

In the event Insurers prevail on their argument that the venBio Fee Award is covered by a subsequent policy year, the Company will pursue coverage under its other insurance policies.

Starr is presently advancing the costs to defend the remaining claims in the venBio Action, i.e., those against the Company as Nominal Defendant and individual defendants Aryeh, Cox, Forrester, and Oliver.  However, all Insurers have reserved their rights to contest coverage for any potential settlement of those claims.

Breach of Contract:

On November 16, 2018, Kapil Dhingra filed a complaint against Immunomedics, Inc., in the Superior Court of New Jersey, Law Division, Morris County, alleging breach of contract and breach of the implied covenant of good faith and fair dealing. In the complaint, Dhingra alleges that Immunomedics breached agreements with Dhingra entered into in 2012 and 2013 that purportedly give him the right to purchase 50,000 shares of Common Stock of Immunomedics for a strike price stated in the agreements. On January 11, 2019, Immunomedics filed a motion for summary judgment and to stay discovery while the motion for summary judgment was pending. On February 5, 2019, Dhingra filed an opposition brief and an amended complaint adding as a plaintiff Kapital Consulting, LLC (together with Dhingra, "Plaintiffs"), and Plaintiffs filed a partial cross-motion for summary judgment. On April 4, 2019, the Court denied all motions without prejudice pending the completion of discovery. Immunomedics continues to dispute the allegations and will seek expedited disposition following discovery.

b. Other Matters:

Immunomedics is also a party to various claims and litigation arising in the normal course of business.

c. Our Licenses

We have obtained licenses from various parties for rights to use, develop and commercialize proprietary technologies and compounds. Currently, we have the following licenses:

Medical Research Council (“MRC”) - We entered into a license agreement with MRC in May 1994, whereby we have obtained a license for certain patent rights with respect to the genetic engineering on monoclonal antibodies. Our agreement does not require any milestone payments, nor have we made any payments to MRC to date. Our agreement with MRC, which expires

18

at the expiration of the last of the licensed patents in 2020, provides for future royalty payments in the low single digits based on a percentage of product sales.

On April 4, 2018, we entered into a license agreement with The Scripps Research Institute ("TSRI"). Pursuant to the license agreement, TSRI granted to us an exclusive, worldwide, sub-licensable, royalty-bearing license to use certain patent rights relating to sacituzumab govitecan. The license agreement expires on a country-by-country basis on the expiration date of the last to expire licensed patent rights in such country covering a licensed product. The license agreement may be terminated by the mutual written consent of us and TSRI, and TSRI may terminate the license agreement upon the occurrence of certain events, including, but not limited to if we do not make a payment due pursuant to the license agreement and fail to cure such non-payment within 30 days after the date of TSRI's written notice of such non-payment. As consideration for the license granted, we made a cash payment of $250,000 to TSRI. Additionally, we will pay TRSI (i) product development milestone payments that range from the mid six-digit dollar figure to the low seven-digit dollar figure and (ii) royalties on net sales of licensed products in the low-single digit percentage figure range capped at an annual amount. We have agreed to use reasonable efforts to develop and market the licensed products.

d. Michael Pehl Separation

On March 13, 2019, the Company entered into a separation agreement (the “Separation Agreement”) with Michael Pehl, the Company’s former Chief Executive Officer, President and member of the Company’s Board. Mr. Pehl resigned as Chief Executive Officer, President and member of the Company’s Board effective February 23, 2019. Pursuant to the Separation Agreement, Mr. Pehl will receive cash payments of approximately $1.0 million over an eighteen-month period. During the nine months ended September 30, 2019, the Company paid approximately $0.3 million to Mr. Pehl, and $0.7 million was accrued for as of September 30, 2019. Mr. Pehl also released the Company from any and all claims with respect to all matters arising out of or related to Mr. Pehl’s employment by the Company and his resignation.

e. Leases

Our operating lease assets primarily represent manufacturing and research and development facilities, warehouses, and offices. Our finance leases primarily represent computer equipment and are not significant. Total operating lease expense was $0.3 million for the three months ended September 30, 2019, and $1.0 million for the nine months ended September 30, 2019. For the three and nine months ended September 30, 2019, cash payments against operating lease liabilities totaled $0.3 million and $1.0 million, respectively. The discount rate used to determine the net present value of the leases at inception was 11.0%. This is the incremental borrowing rate that represents the rate of interest that the Company would expect to pay to borrow an amount equal to the lease payments under similar terms. Our leases both share a remaining lease term of 12.1 years, some of which may include options to extend the leases further. The Company considers these options in determining the lease term used to establish the right-of-use assets and lease liabilities.

Overview

Immunomedics, Inc., a Delaware corporation, together with its subsidiaries (collectively "we," "our," "us," "Immunomedics," or the "Company"), is a clinical-stage biopharmaceutical company that develops monoclonal antibody-based products for the targeted treatment of cancer. Our advanced proprietary technologies allow us to create humanized antibodies that can be used either alone in unlabeled or “naked” form, or conjugated with chemotherapeutics, cytokines or toxins.

We believe that our antibodies have therapeutic potential, in some cases as a naked antibody or when conjugated with chemotherapeutics, cytokines or other toxins to create unique and potentially more effective treatment options. The attachment of effective anti-tumor compounds to antibodies is intended to allow the delivery of these therapeutic agents to tumor sites with better specificity than conventional chemotherapy. This treatment method is designed to optimize the therapeutic window through

21

reducing the systemic exposure of the patient to the therapeutic agents, which ideally minimizes debilitating side effects while maximizing the concentration of the therapeutic agent at the tumor, potentially leading to better efficacy.

Our portfolio of investigational products includes antibody-drug conjugates ("ADCs") that are designed to deliver a specific payload of a chemotherapeutic directly to the tumor while reducing overall toxicities that are usually associated with conventional administration of these chemotherapeutic agents. Our lead ADC product candidate is sacituzumab govitecan (“IMMU-132”). It has received Breakthrough Therapy Designation from the FDA for the treatment of patients with mTNBC who have received at least two prior therapies for metastatic disease.

Our corporate strategy is to commercialize sacituzumab govitecan on our own in the United States for the benefit of patients with mTNBC and the creation of value for our stockholders. On May 21, 2018, we submitted a BLA to the FDA for sacituzumab govitecan for the treatment of patients with mTNBC who have received at least two prior therapies for metastatic disease. On July 18, 2018, we received notification from the FDA that the BLA was accepted for filing and the original application was granted Priority Review with a PDUFA target action date of January 18, 2019. On January 17, 2019, we received a Complete Response Letter ("CRL") from the FDA for the BLA. We subsequently met with the FDA on May 2, 2019 to review the FDA’s findings and discussed our BLA resubmission. Since then, we have developed a detailed plan to address the chemistry, manufacturing, and control (“CMC”) matters raised in the CRL and in our pre-approval inspection. We held another meeting with the FDA on September 27, 2019 to update the FDA on our progress in addressing these matters and to receive feedback from the FDA on our approach. We have dedicated, and continue to commit, significant resources to address the CMC matters identified by the FDA, while, in parallel, preparing our manufacturing facility to be ready for re-inspection by the FDA. We expect to resubmit our BLA to the FDA in the late November or early December 2019 time-frame, which will then commence the 30 day review period by the FDA for acknowledgment of receipt of the submission.

On March 29, 2019, the Company entered into a sales agreement (the "ATM Agreement") with Cowen and Company, LLC ("Cowen") to issue and sell shares of the Company’s common stock, par value $0.01 per share, having an aggregate offering price of up to $150.0 million, from time to time during the term of the ATM Agreement, through an “at-the-market” equity offering program at the Company's sole discretion, under which Cowen will act as the Company’s agent and/or principal. The Company will pay Cowen a commission up to 3.0% of the gross sales proceeds of any common stock sold through Cowen under the ATM Agreement. During the nine months ended September 30, 2019, the Company sold 370,920 shares of common stock with net proceeds of $5.8 million at a weighted average price of $15.95 (excluding commissions) under the ATM Agreement.

On April 5, 2019, we entered into a promotion agreement (the “Promotion Agreement”) with Janssen Biotech Inc., ("Janssen") pursuant to which we will provide non-exclusive product detailing services to Janssen for erdafitinib (the “Product”). Pursuant to the Promotion Agreement, we will provide a dedicated sales team to market the Product, upon approval by the FDA, to oncologists and other targeted health care providers in the United States. Under the terms of the Promotion Agreement, Janssen maintains ownership of the New Drug Application for the Product as well as legal, regulatory, distribution, commercialization and manufacturing responsibilities for the Product, while we will provide product detailing services to Janssen.  Following the achievement of certain sales targets in 2019 and 2020, Janssen will pay us (a) a service fee equal to a percentage in the low double digits of the portion of Cumulative Net Sales (as defined in the Promotion Agreement) in excess of a baseline amount during each of 2019 and 2020, and (b) potential milestone payments of up to $15.0 million when Cumulative Net Sales exceed certain thresholds during each of 2019 and 2020. On April 12, 2019, we were informed that the FDA granted accelerated approval to Janssen's Balversa (erdafitinib) for the treatment of adult patients with locally advanced or metastatic urothelial carcinoma that has a type of susceptible genetic alteration known as FGFR3 or FGFR2, and that has progressed during or following prior platinum-containing chemotherapy. Refer to "Note 2 - Revenue Recognition" for additional information.

On April 29, 2019, we entered into a license agreement (the “License Agreement”) with Everest Medicines II Limited, a China limited company (“Everest”). Pursuant to the License Agreement, we granted Everest an exclusive license to develop and commercialize sacituzumab govitecan in the People’s Republic of China, Taiwan, Hong Kong, Macao, Indonesia, Philippines, Vietnam, Thailand, South Korea, Malaysia, Singapore and Mongolia (the "Territory"). In consideration for entering into the License Agreement, Everest made a one-time, non-refundable upfront payment to us in the aggregate amount of $65.0 million which is recorded as deferred revenue. The License Agreement contains a development milestone payment of $60.0 million based upon our achievement of FDA approval for sacituzumab govitecan. The License Agreement also contains additional development milestone payments in a total amount of up to $180.0 million based upon the achievement of certain other development milestones. In addition, the License Agreement contains sales milestone payments in a total amount of up to $530.0 million based upon the achievement of certain sales milestones. Everest will make royalty payments to us based upon percentages of net sales of sacituzumab govitecan, ranging from 14% to 20%. Refer to "Note 2 - Revenue Recognition" for additional information.

22

As of September 30, 2019, we had $369.2 million in cash, cash equivalents and marketable securities. We believe our projected financial resources are adequate to (i) support our clinical development plan for developing sacituzumab govitecan in mTNBC, advanced urothelial cancer ("UC"), hormone receptor-positive ("HR+")/human epidermal growth factor receptor 2-negative ("HER2-") metastatic breast cancer ("mBC"), non-small cell lung cancer ("NSCLC"), (ii) further build our clinical and manufacturing infrastructure, and (iii) fund operations through 2020. However, in case of regulatory delays or other unforeseen events, we may require additional funding. Potential sources of funding in such a case could include (i) the entrance into potential development and commercial partnerships to advance and maximize our full pipeline for mTNBC and beyond in the United States and globally, and (ii) potential private and capital markets financing including the use of our ATM Agreement. Refer to "Note 7 - Stockholders' Equity" for additional information.

To accelerate the clinical and preclinical development of sacituzumab govitecan, we have entered into clinical collaborations with AstraZeneca to investigate the ADC in earlier lines of therapy for mTNBC, advanced UC and metastatic NSCLC in combination with its checkpoint inhibitor, and with Clovis to combine with its PARP inhibitor in mTNBC, advanced UC and ovarian cancer. We are also working with the University of Wisconsin on a clinical study in prostate cancer and with the Massachusetts General Hospital on another study combining sacituzumab govitecan with Pfizer's PARP inhibitor, talazoparib, in patients with mTNBC. In September 2019, the Company entered into a clinical collaboration with F. Hoffman-La Roche Ltd ("Roche") to evaluate the safety and efficacy of the combination of atezolizumab (Tecentriq^®), a programmed cell death ligand 1 blocking checkpoint inhibitor, and sacituzumab govitecan, as a frontline treatment of patients with metastatic or inoperable locally advanced TNBC. Roche will be responsible for conducting the randomized trial. In September 2019, the Company also entered into a clinical collaboration with GBG Forschungs-GmbH ("GBG"), Neu-Isenburg, Germany, to develop sacituzumab govitecan as a treatment for newly-diagnosed breast cancer patients who do not achieve a pathological complete response following standard neoadjuvant therapy.

We also have a number of other product candidates that target solid tumors and hematologic malignancies in various stages of clinical and preclinical development. They include other ADCs such as labetuzumab govitecan, which binds the CEACAM5 antigen expressed on CRC and other solid cancers, and IMMU-140 which targets HLA-DR for the potential treatment of hematologic malignancies. We believe that our portfolio of intellectual property provides commercially reasonable protection for our product candidates and technologies.

The development and commercialization of successful therapeutic products is subject to numerous risks and uncertainties including, without limitation, the following:

• we may be unable to obtain additional capital through strategic collaborations, licensing, issuance of convertible debt securities or equity financing in order to continue our research and secure regulatory approval of and market our drug;

• the type of therapeutic compound under investigation and nature of the disease in connection with which the compound is being studied;

• our ability, as well as the ability of our partners, to conduct and complete clinical trials on a timely basis;

• the time required for us to comply with all applicable federal, state and foreign legal requirements, including, without limitation, our receipt of the necessary approvals of the FDA, if at all;

• the financial resources available to us during any particular period; and

• many other factors associated with the commercial development of therapeutic products outside of our control.

See Risk Factors in Item 1A of this Quarterly Report.

Critical Accounting Policies and Accounting Estimates

A critical accounting policy is one that is both important to the portrayal of our financial condition and results of operation and requires management's most difficult, subjective or complex judgments, often as a result of the need to make estimates about the effect of matters that are inherently uncertain.

For a description of our significant accounting policies, refer to "Part II, Item 8. Financial Statements and Supplementary Data, Note 2 - Summary of Significant Accounting Policies" in our 2018 Transition Report on Form 10-K. Of these policies, the following are considered critical to an understanding of our Unaudited Condensed Consolidated Financial Statements as they

23

require the application of the most difficult, subjective and complex judgments: stock-based compensation expenses, and interest expense on liability related to sale of future royalties.

Our critical accounting estimates and assumptions impacting the unaudited condensed consolidated financial statements relate to stock-based compensation expense, and interest expense on liability related to sale of future royalties. Refer to "Note 4 - Debt" and "Note 5 - Stock-based Compensation", respectively, for more information.

Recent Accounting Pronouncements

Refer to "Note 1 - Business Overview, Basis of Presentation and Recent Accounting Pronouncements” in the Notes to Unaudited Condensed Consolidated Financial Statements for a discussion of recently adopted accounting pronouncements and accounting pronouncements not yet adopted, and their expected impact on our financial position and results of operations.

Results of Operations

Our results for any interim period, such as those described in the following analysis, are not necessarily indicative of the results for the entire year or any other future period.

Three-Month Period Ended September 30, 2019 Compared to Three-Month Period Ended September 30, 2018

Costs and Expenses

					($ in thousands)
					Increase/(Decrease)
Three Months Ended September 30,	2019		2018		2019 vs 2018
Research and development	$	68,958	$	38,239	$	30,719		80.3%
Sales and marketing	5,933		5,799		134			2.3%
General and administrative	11,880		13,131		(1,251		)	(9.5)%
Total costs and expenses	$	86,771	$	57,169	$	29,602		51.8%

Total costs and expenses for the three months ended September 30, 2019 increased $29.6 million compared to the three months ended September 30, 2018, primarily due to an increase in research and development expenses of $30.7 million, and an increase in sales and marketing expenses of $0.1 million, partially offset by a decrease in general and administrative expenses of $1.3 million. The overall increase is attributed primarily to preparations to launch sacituzumab govitecan for commercial sales in the United States for patients with at least two prior lines of treatment for metastatic TNBC, and to expand clinical development of sacituzumab govitecan into earlier lines of therapy and other indications.

Research and Development

We do not track expenses on the basis of each individual compound under investigation. We evaluate projects under development from an operational perspective, including such factors as results of individual compounds from laboratory/animal testing, patient results and enrollment statistics in clinical trials. It is important to note that multiple product candidates are often tested simultaneously. It is not possible to calculate each antibody’s supply costs. There are many different development processes and test methods that examine multiple product candidates at the same time. We track our costs in the categories discussed below, specifically “research costs” and “product development costs” and by the types of costs outlined below.

Our research costs consist of outside costs associated with animal studies and costs associated with research and testing of our product candidates prior to reaching the clinical stage. Such research costs primarily include personnel costs, facilities, including depreciation, lab supplies, funding of outside contracted research and license fees. Our product development costs consist of costs from preclinical development (including manufacturing), conducting and administering clinical trials and patent expenses.

24

The following table summarizes our research and development costs for the three months ended September 30, 2019, compared to the three months ended September 30, 2018:

					($ in thousands)
					Increase/(Decrease)
Three Months Ended September 30,	2019		2018		2019 vs 2018
Labor	$	11,384	$	8,018	$	3,366		42.0	%
Manufacturing and quality costs	44,881		16,038		28,843			nm
Clinical development and operations	9,308		4,702		4,606			98.0	%
Other	3,385		9,481		(6,096		)	(64.3	)%
Total research and development costs	$	68,958	$	38,239	$	30,719		80.3	%
nm - not meaningful

Research and development costs increased for the three months ended September 30, 2019 by approximately $30.7 million to $69.0 million compared to the three months ended September 30, 2018. The increase in research and development costs for the three months ended September 30, 2019, compared to the three months ended September 30, 2018, relate primarily to preparations for the approval and launch of sacituzumab govitecan in the United States for patients with mTNBC, including outside manufacturers' organizations services costs and outside consulting services to improve our manufacturing and regulatory functions.

Completion of clinical trials may take several years or more. The length of time varies according to the type, complexity and the disease indication of the product candidate. We estimate that clinical trials of the type we generally conduct are typically completed over the following periods:

	Estimated Completion Period
Clinical Phase	(Years)
I	0-1
II	1-2
III	1-4

The duration and cost of clinical trials through each of the clinical phases may vary significantly over the life of a particular project as a result of, among other things, the following factors:

• the length of time required to recruit qualified patients for clinical trials;

• the duration of patient follow-up in light of trial results;

• the number of clinical sites required for trials; and

• the number of patients that ultimately participate.

Sales and Marketing

Sales and marketing expenses increased $0.1 million during the three months ended September 30, 2019, compared to the three months ended September 30, 2018.

Total general and administrative	$	11,880	$	13,131	$	(1,251	)	(9.5	)%

General and administrative expenses for the three months ended September 30, 2019 decreased by approximately $1.3 million compared to the three months ended September 30, 2018, primarily due to decreased legal and advisory fees and consulting services.

Changes in Fair Market Value of Warrant Liabilities

We had no non-cash income or expense for the three months ending September 30, 2019, compared to a $1.2 million of non-cash gain for the three months ended September 30, 2018, due to a decrease in the fair value of outstanding warrants. There were no outstanding warrants as of September 30, 2019.

Interest Expense

Interest expense for the three months ended September 30, 2019 was $9.7 million, compared to $10.1 million for the three months ended September 30, 2018. The $0.4 million decrease was due primarily to changes in the fair value of our debt balances as a result of the RPI agreement. Refer to "Note 4 - Debt" for more information.

Income Tax Expense

There was no income tax expense for the three months ended September 30, 2019 and 2018.

Total costs and expenses	$	233,587	$	148,060	$	85,527		57.8%
nm - not meaningful

Total costs and expenses for the nine months ended September 30, 2019 increased $85.5 million compared to the nine months ended September 30, 2018, primarily due to an increase in research and development expenses of $85.4 million and an increase in sales and marketing expenses of $9.0 million, partially offset by a decrease in general and administrative expenses of $8.8 million. The overall increase is attributed primarily to preparations to launch sacituzumab govitecan for commercial sales in the United States for patients with at least two prior lines of treatment for metastatic TNBC, and to expand clinical development of sacituzumab govitecan into earlier lines of therapy and other indications.

Research and Development

We do not track expenses on the basis of each individual compound under investigation. We evaluate projects under development from an operational perspective, including such factors as results of individual compounds from laboratory/animal testing, patient results and enrollment statistics in clinical trials. It is important to note that multiple product candidates are often tested simultaneously. It is not possible to calculate each antibody’s supply costs. There are many different development processes and test methods that examine multiple product candidates at the same time. We track our costs in the categories discussed below, specifically “research costs” and “product development costs” and by the types of costs outlined below.

Our research costs consist of outside costs associated with animal studies and costs associated with research and testing of our product candidates prior to reaching the clinical stage. Such research costs primarily include personnel costs, facilities, including depreciation, lab supplies, funding of outside contracted research and license fees. Our product development costs consist of costs from preclinical development (including manufacturing), conducting and administering clinical trials and patent expenses.

The following table summarizes our research and development costs for the nine months ended September 30, 2019, compared to the nine months ended September 30, 2018:

					($ in thousands)
					Increase/(Decrease)
Nine Months Ended September 30,	2019		2018		2019 vs 2018

Total research and development costs	$	180,053	$	94,685	$	85,368		90.2	%
nm - not meaningful

Research and development costs increased for the nine months ended September 30, 2019 by approximately $85.4 million to $180.1 million compared to the nine months ended September 30, 2018. The increase in research and development costs for the nine months ended September 30, 2019, compared to the nine months ended September 30, 2018 relate primarily to preparations for the approval and launch of sacituzumab govitecan in the United States for patients with mTNBC, including outside manufacturers' organizations services and outside consulting services to improve our manufacturing and regulatory functions, partially offset by other expenses.

Completion of clinical trials may take several years or more. The length of time varies according to the type, complexity and the disease indication of the product candidate. We estimate that clinical trials of the type we generally conduct are typically completed over the following periods:

	Estimated Completion Period
Clinical Phase	(Years)
I	0-1
II	1-2
III	1-4

The duration and cost of clinical trials through each of the clinical phases may vary significantly over the life of a particular project as a result of, among other things, the following factors:

• the length of time required to recruit qualified patients for clinical trials;

• the duration of patient follow-up in light of trial results;

• the number of clinical sites required for trials; and

• the number of patients that ultimately participate.

Sales and Marketing

Sales and marketing expenses increased $9.0 million during the nine months ended September 30, 2019, compared to the nine months ended September 30, 2018, primarily due to increased headcount and labor expenses related to our sales force.

General and Administrative Expenses

The following table summarizes our general and administrative expenses for the nine months ended September 30, 2019, compared to the nine months ended September 30, 2018:

					($ in thousands)
					(Decrease)/Increase
Nine Months Ended September 30,	2019		2018		2019 vs 2018

Total general and administrative	$	33,374	$	42,124	$	(8,750	)	(20.8	)%

General and administrative expenses for the nine months ended September 30, 2019 decreased by approximately $8.8 million compared to the nine months ended September 30, 2018, primarily due to decreased legal and advisory fees and other expenses.

Changes in Fair Market Value of Warrant Liabilities

We had no non-cash income or expense for the nine months ending September 30, 2019, compared to a $47.8 million non-cash expense for the nine months ended September 30, 2018, due to an increase in the fair value of then outstanding warrants. There were no outstanding warrants as of September 30, 2019.

Interest Expense

Interest expense for the nine months ended September 30, 2019 was $30.3 million, compared to $30.5 million for the nine months ended September 30, 2018. The $0.2 million decrease was due primarily to changes in the fair value of our debt balances as a result of the RPI agreement. Refer to "Note 4 - Debt" for more information.

Income Tax Expense

There was no income tax expense for the nine months ended September 30, 2019, and $0.2 million of income tax expense for the nine months ended September 30, 2018.

Liquidity and Capital Resources

Since its inception in 1982, Immunomedics’ principal sources of funds have been the private and public sale of equity and debt securities, and revenues from licensing agreements, including up-front and milestone payments, funding of development programs, and other forms of funding from collaborations.

As of September 30, 2019, we had $369.2 million in cash, cash equivalents and marketable securities. We believe our projected financial resources are adequate to (i) support our clinical development plan for developing sacituzumab govitecan in mTNBC, advanced urothelial cancer ("UC"), hormone receptor-positive ("HR+")/human epidermal growth factor receptor 2-negative ("HER2-") metastatic breast cancer ("mBC"), non-small cell lung cancer ("NSCLC"), (ii) further build our clinical and manufacturing infrastructure, and (iii) fund operations through 2020. However, in case of regulatory delays or other unforeseen events, we may require additional funding. Potential sources of funding in such a case could include (i) the entrance into potential development and commercial partnerships to advance and maximize our full pipeline for mTNBC and beyond in the United States and globally, and (ii) potential private and capital markets financing including the use of our ATM Agreement. Refer to "Note 7 - Stockholders' Equity" for additional information.

Actual results could differ materially from our expectations as a result of a number of risks and uncertainties, including the risks described in Item 1A Risk Factors, “Factors That May Affect Our Business and Results of Operations,” and elsewhere in this Quarterly Report on Form 10-Q. Our working capital and working capital requirements are affected by numerous factors and such factors may have a negative impact on our liquidity. Principal among these factors are the success of product commercialization and marketing products, the technological advantages and pricing of our products, the impact of the regulatory requirements applicable to us, and access to capital markets that can provide us with the resources, when necessary, to fund our strategic priorities.

Discussion of Cash Flows

The following table summarizes our cash flows for the nine months ended September 30, 2019 and 2018:

	($ in thousands)
	Nine Months Ended September 30,
	2019			2018
Net cash used in operating activities	$	(129,778	)	$	(119,299	)
Net cash (used in) provided by investing activities	(6,514		)	62,664
Net cash provided by financing activities	8,110			577,647

Net cash used in operating activities. Net cash used in operating activities during the nine months ended September 30, 2019 was approximately $129.8 million, compared to $119.3 million during the nine months ended September 30, 2018, an increase in cash used in operating activities of $10.5 million. The increase in cash used in operating activities for the period was primarily due to an increase in the net loss partially offset by an increase of $65.0 million of deferred revenue related to the Everest Agreement, as well as changes in the fair value of warrant liabilities.

Net cash (used in) provided by investing activities. Net cash used in investing activities during the nine months ended September 30, 2019 was $6.5 million, compared to cash provided by investing activities of $62.7 million during the nine months ended September 30, 2018, an increase of approximately $69.2 million, primarily due to a decrease of $74.0 million in proceeds from sales or maturities of marketable securities.

Net cash provided by financing activities. Net cash provided by financing activities during the nine months ended September 30, 2019 was $8.1 million, compared to $577.6 million of cash provided by financing activities during the nine months ended September 30, 2018. The decrease of $569.5 million was due primarily to cash proceeds received from our agreement with RPI in January 2018, as well as the sale of common stock and warrants, net of related expenses in the prior year.

Working Capital and Cash Requirements

Working capital was $320.0 million as of September 30, 2019, compared to $472.8 million as of December 31, 2018. The $152.8 million decrease in working capital was primarily due to increased research and development expenses in clinical trial costs as well as increases in labor related costs in connection with preparations for the approval and launch of sacituzumab govitecan in the United States for patients with mTNBC.

We expect to continue to fund our operations with our current financial resources. However, in case of regulatory delays or other unforeseen events, we may require additional funding. Potential sources of funding include (i) the entrance into various potential strategic partnerships targeted at advancing and maximizing our full pipeline for mTNBC and beyond, (ii) the sales and marketing of sacituzumab govitecan as a third-line therapy for mTNBC in the United States (pending FDA approval), and (iii) potential equity and debt financing transactions including the use of our ATM Agreement. Refer to "Note 7 - Stockholders' Equity" for additional information.

Until we can generate significant cash through (i) the entrance into various potential strategic partnerships towards advancing and maximizing our full pipeline for mTNBC and beyond, or (ii) the sales and marketing of sacituzumab govitecan as a third-line therapy for mTNBC in the United States (pending FDA approval), we expect to continue to fund our operations with our current financial resources. In the future, if we cannot obtain sufficient funding through the above methods, we could be required to finance future cash needs through the sale of additional equity and/or issuance of debt. However, there can be no assurance that we will be able to raise the additional capital needed to complete our pipeline of research and development programs on commercially acceptable terms, if at all. The capital markets have experienced volatility in recent years, which has resulted in uncertainty with respect to availability of capital and hence the timing to meet an entity’s liquidity needs. Our existing debt may also negatively impact our ability to raise additional capital. If we are unable to raise capital on acceptable terms, our ability to continue our business would be materially and adversely affected. Actual results could differ materially from our expectations as a result of a number of risks and uncertainties, including the risks described in Item 1A Risk Factors, “Factors That May Affect Our Business and Results of Operations,” and elsewhere in our Quarterly Report on Form 10-Q. Our working capital and working capital requirements are affected by numerous factors and such factors may have a negative impact on our liquidity. Principal among these factors are the success of product commercialization and marketing products, the technological advantages and pricing

30

of our products, the impact of the regulatory requirements applicable to us, and access to capital markets that can provide us with the resources, when necessary, to fund our strategic priorities.

Off-Balance Sheet Arrangements

We did not have during the periods presented in this quarterly report on Form 10-Q, and we do not currently have, any off-balance sheet arrangements, as defined in the rules and regulations of the SEC.

PART II.    OTHER INFORMATION

ITEM 1.    LEGAL PROCEEDINGS

The information called for by this item is incorporated by reference to "Note 11 - Commitments and Contingencies" of Notes to Unaudited Condensed Consolidated Financial Statements contained in Part I Item 1 of this Quarterly Report on Form 10-Q.

Item 1A.    RISK FACTORS 

Factors That May Affect Our Business and Results of Operations

Investing in our common stock involves a high degree of risk. You should carefully consider the risks described below, as well as the other information in this quarterly report, including our financial statements and the related notes and “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” before deciding whether to invest in our common stock. The occurrence of any of the events or developments described below could harm our business, financial condition, results of operations and growth prospects. In such an event, the market price of our common stock could decline, and you may lose all or part of your investment. Additional risks and uncertainties not presently known to us or that we currently deem immaterial also may impair our business operations

Risks Relating to Our Business, Operations and Product Development 

We have a long history of operating losses and it is likely that our operating expenses will continue to exceed our revenues for the foreseeable future.

We have incurred significant operating losses since our formation in 1982. We continue to spend our cash resources to fund our research and development programs and, subject to adequate funding, we expect these expenses to increase for the foreseeable future. Our only significant sources of revenue in recent years have been derived from collaboration agreements and sales of our LeukoScan^® product in certain European countries. Additionally, the only product sales we have earned to date have come from the limited sales of our LeukoScan^® diagnostic imaging product for which our (i) patent protection has expired and (ii) future sales were discontinued during February 2018. There can be no assurance that we will be profitable in future quarters or other periods. Further, we have made the strategic decision to focus on our therapeutic pipeline. We have never had product sales of any therapeutic product. We expect to experience significant operating losses as we invest further in our research and development activities while simultaneously attempting to develop and commercialize our other therapeutic product candidates. Even if we are able to develop commercially viable therapeutic products, certain obligations the Company has to third parties, including, without limitation, our obligation to pay RPI royalties on certain sacituzumab govitecan revenues pursuant to the Royalty Agreement may erode profitability of such products. If we are unable to develop commercially viable therapeutic products or to license them to third parties, it is likely that we will never achieve significant revenues or become profitable, either of which would jeopardize our ability to continue as a going concern.

We have significant future capital needs and may be unable to raise capital when needed, which could force us to delay or reduce our clinical development efforts.

We believe our projected financial resources are adequate to (i) support our clinical development plan for developing sacituzumab govitecan in mTNBC, advanced urothelial cancer ("UC"), hormone receptor-positive ("HR+")/human epidermal growth factor receptor 2-negative ("HER2-") metastatic breast cancer ("mBC"), non-small cell lung cancer ("NSCLC"), (ii) further build our clinical and manufacturing infrastructure, and (iii) fund operations through 2020. However, in case of regulatory delays or other unforeseen events, we may require additional funding.

We may require additional funding in the future to complete our clinical trials currently planned or underway, continue research and new development programs, and continue operations. Potential sources of funding include (i) the entrance into various potential strategic partnerships targeted at advancing and maximizing our full pipeline for mTNBC and beyond, (ii) the sales and marketing of sacituzumab govitecan as a third-line therapy for mTNBC in the United States (pending FDA approval), and (iii) potential equity and debt financing transactions including the use of our ATM Agreement. Refer to "Note 7 - Stockholders' Equity" for additional information.

Until we can generate significant cash through (i) the entrance into various potential strategic partnerships towards advancing and maximizing our full pipeline for mTNBC and beyond, or (ii) the sales and marketing of sacituzumab govitecan as

32

a third-line therapy for mTNBC in the United States (pending FDA approval), we expect to continue to fund our operations with our current financial resources. In the future, if we cannot obtain sufficient funding through the above methods, we could be required to finance future cash needs through the sale of additional equity and/or issuance of debt. However, there can be no assurance that we will be able to raise the additional capital needed to complete our pipeline of research and development programs on commercially acceptable terms, if at all. The capital markets have experienced volatility in recent years, which has resulted in uncertainty with respect to availability of capital and hence the timing to meet an entity’s liquidity needs. Our existing debt may also negatively impact our ability to raise additional capital. If we are unable to raise capital on acceptable terms, our ability to continue our business would be materially and adversely affected.

Other than our pending BLA resubmission for sacituzumab govitecan for patients with metastatic triple-negative breast cancer, our other most advanced therapeutic product candidates are still only in the clinical development stage, and may require us to raise capital in the future in order to fund further expensive and time-consuming studies before they can even be submitted for final regulatory approval. A failure of a clinical trial could severely harm our business and results of operations.

Clinical trials involve the administration of a product candidate to patients who are already extremely ill, making patient enrollment often difficult and expensive. Moreover, even in ideal circumstances where the patients can be enrolled and then followed for the several months or more required to complete the study, the trials can be suspended, terminated, delayed or otherwise fail for any number of reasons, including:

• later-stage clinical trials may raise safety or efficacy concerns not readily apparent in earlier trials or fail to meet the primary endpoint;

• unforeseen difficulties in manufacturing the product candidate in compliance with all regulatory requirements and in the quantities needed to complete the trial which may become cost-prohibitive;

• we or any of our collaboration partners may experience delays in obtaining, or be unable to obtain, agreement for the conduct of our clinical trials from the FDA, institutional review boards ("IRBs"), or other reviewing entities at clinical sites selected for participation in our clinical trials;

• while underway, the continuation of clinical trials may be delayed, suspended or terminated due to modifications to the clinical trial’s protocols based on interim results obtained or changes required or conditions imposed by the FDA, an IRB, a data and safety monitoring board (“DSMB”), or any other regulatory authority;

• our third-party contractors may fail to meet their contractual obligations to us in a timely manner;

• the FDA or other regulatory authorities may impose a clinical hold, for example based on an inspection of the clinical trial operations or trial sites;

• we or any of our collaboration partners may suspend or cease trials in our or their sole discretion;

• during the long trial process alternative therapies may become available which make further development of the product candidate impracticable; and

• if we are unable to obtain the additional capital we need to fund all of the clinical trials we foresee, we may be forced to cancel or otherwise curtail such trials and other studies.

Any substantial delay in successfully completing clinical trials for our product candidates, sacituzumab govitecan and labetuzumab govitecan, could severely harm our business and results of operations.

Moreover, principal investigators for our clinical trials may serve as scientific advisers or consultants to us from time to time and receive compensation in connection with such services. Under certain circumstances, the Company may be required to report some of these relationships to the FDA. The FDA may conclude that a financial relationship between the Company and a principal investigator has created a conflict of interest or otherwise affected interpretation of the study. The FDA may therefore question the integrity of the data generated at the applicable clinical trial site and the utility of the clinical trial itself may be jeopardized. This could result in a delay in approval, or rejection, of our marketing applications by the FDA and may ultimately lead to the denial of regulatory approval of one or more of our product candidates.

33

Our clinical trials may not adequately show that our drugs are safe or effective, and a failure to achieve the planned endpoints could result in termination of product development.

Progression of our drug products through the clinical development process is dependent upon our trials indicating our drugs have adequate safety and efficacy in the patients being treated by achieving pre-determined safety and efficacy endpoints according to the trial protocols. Failure to achieve either of these endpoints could result in delays in our trials, require the performance of additional unplanned trials or require termination of any further development of the product for the intended indication.

These factors could result in delays in the development of our product candidates and could result in significant unexpected costs or the termination of programs.

Should the clinical development process be successfully completed, our ability to derive revenues from the sale of therapeutics will depend upon our first obtaining FDA as well as foreign regulatory approvals, all of which are subject to a number of unique risks and uncertainties.

Even if we are able to demonstrate the safety and efficacy of our product candidates in clinical trials, if we fail to gain timely approval to commercialize our product candidates from the FDA and other foreign regulatory authorities, we will be unable to generate the revenues we will need to build our business. The FDA or comparable regulatory authorities in other countries may delay, limit or deny approval of our product candidates for various reasons. For example, such authorities may disagree with the design, scope or implementation of our clinical trials; or with our interpretation of data from our preclinical studies or clinical trials; or may otherwise take the position that our product candidates fail to meet the requirements and standards for regulatory approval. There is limited FDA precedent or guidance on ADCs, and ADC product candidates may present more complex review considerations than conventional drugs, given their biologic (antibody), drug, and linker components. There are numerous FDA personnel assigned to review different aspects of a BLA, and uncertainties can be presented by their ability to exercise judgment and discretion during the review process. During the course of review, the FDA may request or require additional preclinical, clinical, chemistry, manufacturing, and control (“CMC”), or other data and information, and the development and provision of these data and information may be time consuming and expensive. Regulatory approvals may not be granted on a timely basis, if at all, and even if and when they are granted, they may not cover all the indications for which we seek approval. On May 21, 2018, we submitted a Biologics License Application (“BLA”) to the FDA for sacituzumab govitecan for the treatment of patients with mTNBC who have received at least two prior therapies for metastatic disease. On July 18, 2018, we received notification from the FDA that the BLA was accepted for filing and the original application was granted Priority Review with a PDUFA target action date of January 18, 2019. On January 17, 2019, we received a Complete Response Letter (“CRL”) from the FDA for the BLA, which identified CMC matters for the Company to address to place our application in condition for approval. On February 4, 2019, we received a written communication from the FDA enclosing the Establishment Inspection Report (“EIR”) from the chemistry, manufacturing and controls BLA pre-approval inspection conducted by the FDA at the Company’s Morris Plains, New Jersey antibody manufacturing facility for our ADC product candidate sacituzumab govitecan, which took place from August 6, 2018 through August 14, 2018. The FDA also notified the Company that the FDA will be conducting a re-inspection of the Company’s Morris Plains, New Jersey antibody manufacturing facility as part of the BLA resubmission process. The Company met with the FDA on May 2, 2019 to review the FDA’s findings and discussed the Company’s BLA resubmission and held another meeting with the FDA on September 27, 2019 to update the FDA on our progress in addressing the items identified in the CRL and in our pre-approval inspection and to receive feedback from FDA on our approach. The Company has developed a detailed plan and has dedicated, and continues to commit, significant resources to addressing the CMC matters identified by the FDA, while, in parallel, preparing our manufacturing facility to be ready for re-inspection by the FDA. If the FDA determines that these actions were not sufficient, or based on the re-inspection FDA officials do not recommend approval relative to our manufacturing facility, or if information deemed necessary by the FDA cannot be provided as part of our BLA submission or during the review period as deemed appropriate on a timely basis, such events could further delay the progress of our BLA and could require additional Company actions that cannot be completed during the review period which may adversely impact our business. Further, while we may develop a product candidate with the intention of addressing a large, unmet medical need, the FDA may only approve the use of the drug for indications affecting a relatively small number of patients, thus greatly reducing the market size and our potential revenues. The approvals may also contain significant limitations in the form of warnings, precautions or contraindications with respect to conditions of use, which could further narrow the size of the market. In certain countries, even if the health regulatory authorities approve a drug, it cannot be marketed until pricing for the drug is also approved. Finally, even after approval can be obtained, we may be required to recall or withdraw a product as a result of newly discovered safety or efficacy concerns, either of which would have a materially adverse effect on our business and results of operations.

In order to fund future operations, we will need to raise significant amounts of additional capital. Because it can be difficult for a mid-cap company like ours to raise equity capital on acceptable terms, we cannot assure you that we will be able to obtain the necessary capital when we need it, or on acceptable terms, if at all.

34

Even if our technologies and product candidates are superior, if we lack the capital needed to bring our future products to market, we will never be successful. We have obtained the capital necessary to fund our research and development programs to date primarily from the following sources:

• upfront payments, milestone payments, and payments for limited amounts of our antibodies received from licensing partners;

• proceeds from the public and private sale of our equity or debt securities; and

• limited product sales of LeukoScan^® (which were discontinued during February 2018), licenses, grants and interest income from our investments.

Over the long term, we expect to commercialize sacituzumab govitecan in mTNBC in the United States and globally, to expand sacituzumab govitecan to treat patients with other solid tumors, including UC, HR+/HER2- mBC, NSCLC and other serious cancers, to expand research and development activities to continue to expand and we do not believe we will have adequate cash to continue commercial expansion and development of sacituzumab govitecan, or to complete development of product candidates in line with our pipeline included in our long term corporate strategy. Our capital requirements are dependent on numerous factors, including:

• the rate of progress of commercialization of sacituzumab govitecan in mTNBC and our ability to develop it for other cancers;

• the rate at which we progress our research programs and the number of product candidates we have in preclinical and clinical development at any one time;

• the cost of conducting clinical trials involving patients in the United States, Europe and possibly elsewhere;

• our need to establish the manufacturing capabilities necessary to produce the quantities of our product candidates we project we will need;

• the time and costs involved in obtaining FDA and foreign regulatory approvals;

• the cost of first obtaining, and then defending, our patent claims and other intellectual property rights; and

• our ability to enter into licensing and other collaborative agreements to help offset some of these costs.

There may be additional cash requirements for many reasons, including, but not limited to, changes in our commercial expansion plans, our research and development plans, the need for unexpected capital expenditures or costs associated with any acquisitions of other businesses, assets or technologies that we may choose to undertake and marketing and commercialization of our product candidates. If we deplete our existing capital resources, we will be required to either obtain additional capital quickly, or significantly reduce our operating expenses and capital expenditures, either of which could have a material adverse effect on us.

Until we can generate significant cash through either (i) the entrance into various potential strategic partnerships targeted at advancing and maximizing the Company’s full pipeline for mTNBC and beyond, or (ii) the sales and marketing of sacituzumab govitecan as a third-line therapy for mTNBC in the United States (pending FDA approval), we expect to continue to fund our operations with our current financial resources. We believe our projected financial resources are adequate to (i) support our clinical development plan for developing sacituzumab govitecan in mTNBC, advanced urothelial cancer ("UC"), hormone receptor-positive ("HR+")/human epidermal growth factor receptor 2-negative ("HER2-") metastatic breast cancer ("mBC"), non-small cell lung cancer ("NSCLC"), (ii) further build our clinical and manufacturing infrastructure, and (iii) fund operations through 2020. However, in case of regulatory delays or other unforeseen events, we may require additional funding. If, however, we cannot obtain sufficient funding through the entrance into various potential strategic partnerships targeted at advancing and maximizing the Company’s full pipeline for mTNBC and beyond, we could be required to finance future cash needs through the sale of additional equity and/ or issuance of debt. However, there can be no assurance that we will be able to raise the additional capital needed to complete our pipeline of research and development programs on commercially acceptable terms, if at all. The capital markets have experienced volatility in recent years, which has resulted in uncertainty with respect to availability of capital and hence the timing to meet an entity’s liquidity needs. The Company’s existing debt will also negatively impact the Company’s ability to raise additional capital. If the Company is unable to raise capital on acceptable terms, its ability to continue its business would be materially and adversely

35

affected. Having insufficient funds may require us to delay, scale-back, or eliminate some or all of our programs, or renegotiate less favorable terms than we would otherwise choose. Failure to obtain adequate financing also may adversely affect our ability to operate as a going concern.

Additionally, if we raise funds by issuing equity securities, dilution to existing stockholders would result; and if we raise funds by incurring additional debt financing, the terms of the debt may involve future cash payment obligations and/or conversion to equity as well as restrictions that may limit our ability to operate our business.

If we, or any of our collaboration partners, or our or their contract manufacturers, cannot successfully and efficiently manufacture the compounds that make up our products and product candidates, our ability, and the ability of our collaboration partners, to sell products and conduct clinical trials will be impaired.

Our ability to conduct our preclinical and clinical research and development programs depends, in large part, upon our ability to manufacture our proprietary compounds in accordance with the FDA and other regulatory requirements. We have limited historical experience in manufacturing these compounds in significant quantities, and we may not be able to do so in the quantities required to commercialize these products. Any interruption in manufacturing across the supply chain, whether by natural acts or otherwise, could significantly and adversely affect our operations, and delay our research and development programs.

We and our collaboration partners also depend on third parties to provide certain raw materials, and contract manufacturing and processing services. All manufacturers of biopharmaceutical products must comply with current cGMPs, required by the FDA and other regulatory agencies. Such regulations address, among other matters, controls in manufacturing processes, quality control and quality assurance requirements and the maintenance of proper records and documentation. The FDA and other regulatory agencies routinely inspect manufacturing facilities, including in connection with the review of a BLA. The FDA generally will issue a notice on Form 483 if it finds issues with respect to its inspections, to which the facility must adequately respond in order to avoid escalated regulatory concerns. If our manufacturing facility or those facilities of our collaboration partners and our respective contract manufacturers or processors do not comply with applicable cGMPs and other regulatory requirements, in addition to regulatory enforcement, we may be subject to product liability claims, we may be unable to meet clinical demand for our products, and we could suffer delays in the progress of clinical trials for products under development and of potential approval and commercialization.

Although historically we have been a research and development company, we currently plan to commercialize our lead product candidate internally rather than license such asset. There can be no assurance that we will be successful in developing and expanding commercial operations or balancing our research and development activities with our commercialization activities.

We have historically been engaged primarily in research and development activities, but plan to commercialize our lead product candidate, sacituzumab govitecan, ourselves. There can be no assurance that we will be able to successfully manage the balance of our research and development operations with our planned commercialization activities. Potential investors should be aware of the problems, delays, expenses and difficulties frequently encountered by companies balancing development of product candidates, which can include problems such as unanticipated issues relating to clinical trials and receipt of approvals from the FDA and foreign regulatory bodies, with commercialization efforts, which can include problems relating to managing manufacturing and supply, reimbursement, marketing problems and additional costs. Our product candidates will require significant additional research and clinical trials, and we will need to overcome significant regulatory burdens prior to commercialization in the United States and other countries. In addition, we may be required to spend significant funds on building out our commercial operations. If we are unable to develop commercially viable therapeutic products, certain obligations the Company has to third parties, including, without limitation, our obligation to pay RPI royalties on certain sacituzumab govitecan revenues pursuant to the funding agreement may also erode profitability of this product. There can be no assurance that after the expenditure of substantial funds and efforts, we will successfully develop and commercialize any of our product candidates, generate any significant revenues or ever achieve and maintain a substantial level of sales of our products.

We may not successfully establish and maintain collaborative and licensing arrangements, which could adversely affect our ability to develop and commercialize certain of our product candidates. Any of our collaboration partners may not adequately perform their responsibilities under our agreements, which could adversely affect our development and commercialization program.

A key element of our business strategy has been to develop, market and commercialize our product candidates through collaborations with more established pharmaceutical companies. To the extent we continue to rely on this business strategy, we may not be able to maintain or expand these licenses and collaborations or establish additional licensing and collaboration

36

arrangements necessary to develop and commercialize any of our product candidates. Even if we are able to maintain or establish licensing or collaboration arrangements, these arrangements may not be on favorable terms and may contain provisions that will restrict our ability to develop, test and market our product candidates. Any failure to maintain or establish licensing or collaboration arrangements on favorable terms could adversely affect our business prospects, financial condition or ability to develop and commercialize our product candidates.

We expect to rely at least in part on third party collaborators to perform a number of activities relating to the development and commercialization of certain of our product candidates, including the manufacturing of product materials, the design and conduct of clinical trials for certain of our product candidates, and potentially the obtaining of regulatory approvals and marketing and distribution of any successfully developed products. Our collaborative partners may also have or acquire rights to control aspects of our product development and clinical programs. As a result, we may not be able to conduct these programs in the manner or on the time schedule we currently contemplate. In addition, if any of these collaborative partners withdraw support for our programs or product candidates or otherwise impair their development, our business could be negatively affected. Our expenses may also increase as a result of our plan to undertake these activities internally to commercialize sacituzumab govitecan.

In addition, our success depends on the performance of our collaborators of their responsibilities under these arrangements. Some potential collaborators may not perform their obligations in a timely fashion or in a manner satisfactory to us. Because such agreements may be exclusive, we may not be able to enter into a collaboration agreement with any other company covering the same product field during the applicable collaborative period. In addition, our collaborators’ competitors may not wish to do business with us at all due to our relationship with our collaborators. If we are unable to enter into additional product discovery and development collaborations, our ability to sustain or expand our business will be significantly diminished.

Our future success will depend upon our ability to first obtain and then adequately protect our patent and other intellectual property rights, as well as avoiding the infringement of the rights of others.

Our future success will be highly dependent upon our ability to first obtain and then defend the patent and other intellectual property rights necessary for the commercialization of our product candidates. We have filed numerous patent applications on the technologies and processes that we use in the United States and certain foreign countries. Although we have obtained a number of issued United States patents to date, the patent applications owned or licensed by us may not result in additional patents being issued. Moreover, these patents may not afford us the protection we need against competitors with similar technologies or products. A number of jurisdictions where we have sought, or may in the future choose to seek, intellectual property protection, have intellectual property laws and patent offices which are still developing. Accordingly, we may have difficulty obtaining intellectual property protection in these markets, and any intellectual property protections which we do obtain may be less protective than in the United States, which could have an adverse effect on our operations and financial prospects.

The successful development of therapeutic products frequently requires the application of multiple technologies that may be subject to the patent or other intellectual property rights of third parties. Although we believe it is likely we will need to license technologies and processes from third parties in the ordinary course of our business, we are not currently aware of any material conflict involving our technologies and processes with any valid patents or other intellectual property rights owned or licensed by others that would affect commercial sales of sacituzumab govitecan or other products starting in 2020. In the event that a third party was to claim such a conflict existed, they could sue us for damages as well as seek to prevent us from commercializing our product candidates. It is possible that a third party could successfully claim that our products infringe on their intellectual property rights. Uncertainties resulting from the litigation and continuation of patent litigation or other proceedings could have a material adverse effect on our ability to compete in the marketplace. Any patent litigation or other proceeding, even if resolved in our favor, would require significant financial resources and management time.

Some of our competitors may be able to sustain these costs more effectively than we can because of their substantially greater financial and managerial resources. If a patent litigation or other proceeding is resolved unfavorably to us, we may be enjoined from manufacturing or selling our products without a license from the other party, in addition to being held liable for significant damages. We may not be able to obtain any such license on commercially acceptable terms, if at all.

In addition to our reliance on patents, we attempt to protect our proprietary technologies and processes by relying on trade secret laws, nondisclosure and confidentiality agreements and licensing arrangements with our employees and other persons who have access to our proprietary information. These agreements and arrangements may not provide meaningful protection for our proprietary technologies and processes in the event of unauthorized use or disclosure of such information. In addition, our competitors may independently develop substantially equivalent technologies and processes or otherwise gain access to our trade secrets or technology, either of which could materially and adversely affect our competitive position.

37

Expiry of our intellectual property rights could lead to increased competition.

Even where we are able to obtain and then defend patent and other intellectual property rights necessary for research, development and commercialization of our product candidates, such intellectual property rights will be for a limited term. Where patents which we own or license expire, the technology comprising the subject of the patent may be utilized by third parties in research and development or competing products (for example, biosimilars of a patented product may be manufactured by third parties once the patent expires). While we endeavor to maintain robust intellectual property protection, as our existing issued patents expire, it may materially and adversely affect our competitive position.

We face substantial competition in the biotechnology industry and may not be able to compete successfully against one or more of our competitors.

The biotechnology industry is highly competitive, particularly in the area of therapeutic oncology products. In recent years, there have been extensive technological innovations achieved in short periods of time, and it is possible that future technological changes and discoveries by others could result in our products and product candidates quickly becoming uncompetitive or obsolete. A number of companies, including Amgen, Astellas Pharma, AstraZeneca, Bayer Healthcare Pharmaceuticals, Bristol-Myers Squibb, Celgene, Daiichi Sankyo, Eli Lilly, Genmab, GlaxoSmithKline, Immunogen, Johnson & Johnson, Merck, Merck Serono, Novartis, Pfizer, Roche, and Seattle Genetics, are engaged in the development of therapeutic oncology products. Many of these companies have significantly greater financial, technical and marketing resources than we do. In addition, many of these companies have more established positions in the pharmaceutical industry and are therefore better equipped to develop, commercialize and market oncology products. Even some smaller competitors may obtain a significant competitive advantage over us if they are able to discover or otherwise acquire patentable inventions, form collaborative arrangements or merge with larger pharmaceutical companies. Further, even if we are able to successfully develop and commercialize products, other manufacturers operating in emerging markets may also have a competitive advantage over us with respect to competing products due to their ability to manufacture with a lower cost base.

We expect to face increasing competition from universities and other non-profit research organizations. These institutions carry out a significant amount of research and development in the field of antibody-based technologies and they are increasingly aware of the commercial value of their findings. As a result, they are demanding greater patent and other proprietary rights, as well as licensing and future royalty revenues. It is possible that such competition could come from universities with which we have, or have previously had, collaborative research and development relationships, notwithstanding our efforts to protect our intellectual property in the course of such relationships.

We may be liable for contamination or other harm caused by hazardous materials that we use in the operations of our business.

In addition to laws and regulations enforced by the FDA, we are also subject to regulation under various other foreign, federal, state and local laws and regulations. Our manufacturing and research and development programs involve the controlled use of viruses, hazardous materials, chemicals and various radioactive compounds. The risk of accidental contamination or injury from these materials can never be completely eliminated, and if an accident occurs, we could be held liable for any damages that result, which could exceed our available resources.

The nature of our business exposes us to significant liability claims, and our insurance coverage may not be adequate to cover any future claims.

The use of our compounds in clinical trials and any future sale exposes us to liability claims that could be substantial. These claims might be made directly by healthcare providers, medical personnel, patients, consumers, pharmaceutical companies, and others selling or distributing our compounds. While we currently have product liability insurance that we consider adequate for our current needs, we may not be able to continue to obtain comparable insurance in the future at an acceptable cost, if at all. If for any reason we cannot maintain our existing or comparable liability insurance, our ability to clinically test and market products could be significantly impaired. Moreover, the amount and scope of our insurance coverage, as well as the indemnification arrangements with third parties upon which we rely, may be inadequate to protect us in the event of a successful product liability claim. Any successful claim in excess of our insurance coverage could materially and adversely affect our financial condition and operating results.

Certain potential for conflicts of interest, both real and perceived, exist which could result in expensive and time-consuming litigation.

38

Certain of our former officers and directors have relationships and agreements, both with us as well as among themselves and their respective affiliates, which create the potential for both real, as well as perceived, conflicts of interest. These include Dr. David M. Goldenberg, our former Chairman of our Board of Directors, our former Chief Scientific Officer and our former Chief Patent Officer, and Ms. Cynthia L. Sullivan, a former Director and our former President and Chief Executive Officer (who is also the wife of Dr. Goldenberg). Dr. Goldenberg is also a minority stockholder of our majority-owned subsidiary, IBC. Dr. Goldenberg was the primary inventor of new intellectual property for Immunomedics and IBC and was largely responsible for allocating ownership between the two companies. Immunomedics has incurred expenses on behalf of the IBC operations, including interest, over the past fifteen years. As of September 30, 2019, IBC has a liability to Immunomedics Inc. which is eliminated in consolidation.

On January 8, 2018, Morris Rosenberg joined the Company as Chief Technology Officer and became a full-time employee and was permitted to continue to provide certain limited outside consulting services through M Rosenberg BioPharma Consulting LLC.

On March 5, 2019, we entered into a Letter Agreement with Scott Canute, a member of our Board of Directors, in connection with his appointment as Executive Director of the Company.

As a result of these and other relationships, the potential for both real and perceived conflicts of interest exists and disputes could arise over the allocation of funds, research projects and ownership of intellectual property rights. In addition, in the event that we become involved in stockholder litigation regarding these potential conflicts, we might be required to devote significant resources and management time defending the Company from these claims, which could adversely affect our results of operations.

The commercial success of our product candidates depends on the availability and sufficiency of third-party payor coverage and reimbursement. Given that recent cancer therapeutics for solid cancers such as the ones we are developing can cost approximately in excess of $12,500 a month, even if our product candidates become available for sale it is likely that federal and state governments, insurance companies and other payors of health care costs will try to first limit the use of these drugs to certain patients, and may be reluctant to provide a level of reimbursement that permits us to earn a significant profit on our investment, if any.

Our ability to successfully commercialize therapeutic products will depend, in significant part, on the extent to which hospitals and physicians can obtain appropriate reimbursement levels for the cost of our products and related treatment. Third-party payors are increasingly challenging the prices charged for diagnostic and therapeutic products and related services. In addition, legislative proposals to reform health care or reduce government insurance programs may result in lower prices or the actual inability of prospective customers to purchase our products. Furthermore, even if reimbursement is available, it may not be available at price levels sufficient for us to realize a positive return on our investment.

The United States government, state legislatures and foreign governmental entities have shown significant interest in implementing cost containment programs to limit the growth of government-paid healthcare costs, including price controls, restrictions on reimbursement and coverage and requirements for substitution of generic products for branded prescription drugs. Adoption of government controls and measures, and tightening of restrictive policies in jurisdictions with existing controls and measures, could exclude or limit our product candidates from coverage and limit payments for pharmaceuticals.

In addition, we expect that increased emphasis on managed care and cost containment measures in the United States by third-party payors and government authorities to continue and will place pressure on pharmaceutical pricing and coverage. Coverage policies and third-party reimbursement rates may change at any time. Even if favorable coverage and reimbursement status is attained for one or more product candidates for which we receive regulatory approval, less favorable coverage policies and reimbursement rates may be implemented in the future.

If we are unable to obtain and maintain sufficient third-party coverage and adequate reimbursement for our product candidates, the commercial success of our product candidates may be greatly hindered and our financial condition and results of operations may be materially and adversely affected.

Our products may not achieve market acceptance.

If any of our product candidates fail to achieve sufficient market acceptance, we may not be able to generate sufficient revenue to become profitable. The degree of market acceptance of our product candidates, if and when they are approved for commercial sale, will depend on a number of factors, including but not limited to:

39

• the timing of our receipt of marketing approvals, the terms of such approvals and the countries in which such approvals are obtained;

• the safety, efficacy, reliability and ease of administration of our product candidates;

• the prevalence and severity of undesirable side effects and adverse events;

• the extent of the limitations or warnings required by the FDA or comparable regulatory authorities in other countries to be contained in the labeling of our product candidates;

• the clinical indications for which our product candidates are approved;

• the availability and perceived advantages of alternative therapies;

• any publicity related to our product candidates or those of our competitors;

• the quality and price of competing products;

• our ability to obtain third-party payor coverage and sufficient reimbursement;

• the willingness of patients to pay out of pocket in the absence of third-party payor coverage; and

• the selling efforts and commitment of our commercialization collaborators.

If our approved product candidates fail to receive a sufficient level of market acceptance, our ability to generate revenue from sales of our product candidates will be limited, and our business and results of operations may be materially and adversely affected.

A portion of our funding has come from federal government grants and research contracts. Due to reductions in funding, we may not be able to rely on these grants or contracts as a continuing source of funds.

During the last few years, we have generated revenues from awards made to us by the National Institutes of Health and the Department of Defense to partially fund some of our programs. We cannot rely on grants or additional contracts as a continuing source of funds. Funds available under these grants and contracts must be applied by us toward the research and development programs specified by the government rather than for all our programs generally. The government’s obligation to make payments under these grants and contracts is subject to appropriation by the United States Congress for funding in each year. It is possible that Congress or the government agencies that administer these government research programs will continue to scale back these programs or terminate them due to their own budgetary constraints, as they have recently been doing. Additionally, these grants and research contracts are subject to adjustment based upon the results of periodic audits performed on behalf of the granting authority. Consequently, the government may not award grants or research contracts to us in the future, and any amounts that we derive from existing awards may be less than those received to date. In those circumstances, we would need to provide funding on our own, obtain other funding, or scale back or terminate the affected program. In particular, we cannot assure you that any currently contemplated or future efforts to obtain funding for our product candidate programs through government grants or contracts will be successful, or that any such arrangements which we do conclude will supply us with sufficient funds to complete our development programs without providing additional funding on our own or obtaining other funding. Where funding is obtained from government agencies or research bodies, our intellectual property rights in the research or technology funded by the grant are typically subject to certain licenses to such agencies or bodies, which could have an impact on our utilization of such intellectual property in the future.

We face a number of risks relating to the maintenance of our information systems and our use of information relating to clinical trials.

In managing our operations, we rely on computer systems and electronic communications, including systems relating to record keeping, financial information, sourcing, and back-up and the Internet (“Information Systems”). Our Information Systems include the electronic storage of financial, operational, research, patient and other data. Our Information Systems may be subject to interruption or damage from a variety of causes, including power outages, computer and communications failures, system capacity constraints, catastrophic events (such as fires, tornadoes and other natural disasters), cyber risks, computer viruses and security breaches. If our Information Systems cease to function properly, are damaged or are subject to unauthorized access, we

40

may suffer interruptions in our operations, be required to make significant investments to fix or replace systems and/or be subject to fines, penalties, lawsuits, or government action. The realization of any of these risks could have a material adverse effect on our business, financial condition and results of operations. Our clinical trials information and patient data (which may include personally identifiable information) is part of our Information Systems and is therefore subject to all of the risks set forth above, notwithstanding our efforts to code and protect such information.

Risks Related to Government Regulation of our Industry

Legislative or regulatory reform of the healthcare system may affect our ability to sell our products profitably.

In recent years, there have been numerous initiatives on the federal and state levels in the United States for comprehensive reforms affecting the payment for, the availability of, and reimbursement for, healthcare services. There have been a number of federal and state proposals during the last few years regarding the pricing of pharmaceutical and biopharmaceutical products, limiting coverage and reimbursement for drugs and other medical products, government control and other changes to the healthcare system in the United States. For example, the Patient Protection and Affordable Care Act (“ACA”) and the Health Care and Education Reconciliation Act of 2010, which amends the ACA, collectively, the United States Health Reform Laws, were signed into law in the United States in March 2010.

Among the provisions of the ACA of importance to the pharmaceutical industry are the following:

• the Medicaid Drug Rebate Program requires pharmaceutical manufacturers to enter into and have in effect a national rebate agreement with the Secretary of the Department of Health and Human Services as a condition of Medicare Part B and Medicaid coverage of the manufacturer's outpatient drugs furnished to Medicaid patients. Effective in 2010, the ACA made several changes to the Medicaid Drug Rebate Program, including increasing pharmaceutical manufacturers' rebate liability by raising the minimum basic Medicaid rebate on most branded prescription drugs from 15.1% of average manufacturer price, or AMP, to 23.1% of AMP, establishing new methodologies by which AMP is calculated and rebates owed by manufacturers under the Medicaid Drug Rebate Program are collected for drugs that are inhaled, infused, instilled, implanted or injected, adding a new rebate calculation for "line extensions" (i.e., new formulations, such as extended release formulations) of solid oral dosage forms of branded products, expanding the universe of Medicaid utilization subject to drug rebates to covered drugs dispensed to individuals who are enrolled in Medicaid managed care organizations, and expanding the population potentially eligible for Medicaid drug benefits;

• the expansion of eligibility criteria for Medicaid programs by, among other things, allowing states to offer Medicaid coverage to additional individuals beginning in April 2010 and by adding new mandatory eligibility categories for certain individuals with income at or below 133.0% of the federal poverty level beginning in 2014, thereby potentially increasing both the volume of sales and manufacturers' Medicaid rebate liability;

• in order for a pharmaceutical product to receive federal reimbursement under the Medicare Part B and Medicaid programs or to be sold directly to United States government agencies, the manufacturer must extend discounts to entities eligible to participate in the 340B drug pricing program. The required 340B discount on a given product is calculated based on the AMP and Medicaid rebate amounts reported by the manufacturer. Effective in 2010, the ACA expanded the types of entities eligible to receive discounted 340B pricing, although, under the current state of the law, with the exception of children's hospitals, these newly eligible entities will not be eligible to receive discounted 340B pricing on orphan drugs when used for the orphan indication. In addition, as 340B drug pricing is determined based on AMP and Medicaid rebate data, the revisions to the Medicaid rebate formula and AMP definition described above could cause the required 340B discount to increase. Recent proposed guidance from the United States Department of Health and Human Services Health Resources and Services Administration, if adopted in its current form, may affect manufacturers' rights and liabilities in conducting audits and resolving disputes under the 340B program;

• the ACA imposed a requirement on manufacturers of branded drugs to provide a 50% (and 70% commencing on January 1, 2019) discount off the negotiated price of branded drugs dispensed to Medicare Part D patients in the coverage gap (i.e., the "donut hole");

• the ACA imposed an annual, nondeductible fee on any entity that manufactures or imports certain branded prescription drugs, apportioned among these entities according to their market share in certain government healthcare programs, although this fee would not apply to sales of certain products approved exclusively for orphan indications;

• the ACA implemented the Physician Payments Sunshine Act;

41

• the ACA requires annual reporting of drug samples that manufacturers and distributors provide to physicians;

• the ACA expanded healthcare fraud and abuse laws in the United States, including the False Claims Act and the federal Anti-Kickback Statute, new government investigative powers and enhanced penalties for non-compliance;

• the ACA established a licensing framework for follow-on biologics;

• the ACA established the Patient-Centered Outcomes Research Institute to oversee, identify priorities in and conduct comparative clinical effectiveness research, along with the funding for such research. The research conducted by the Patient-Centered Outcomes Research Institute may affect the market for certain pharmaceutical products by influencing decisions relating to coverage and reimbursement rates; and

• the ACA established the Center for Medicare and Medicaid Innovation within the Centers for Medicare & Medicaid Center ("Innovation Center"), to test innovative payment and service delivery models to lower Medicare and Medicaid spending, potentially including prescription drug spending. The Innovation Center has been funded through 2019, and funding will be automatically renewed for each 10-year budget window thereafter.

Some of the provisions of the ACA have yet to be implemented, and there have been judicial and Congressional challenges to certain aspects of the ACA, as well as recent efforts by the Trump administration to repeal or replace certain aspects of the ACA. Since January 2017, President Trump has signed two Executive Orders and other directives designed to delay the implementation of certain provisions of the ACA or otherwise circumvent some of the requirements for health insurance mandated by the ACA. Concurrently, Congress has considered legislation that would repeal or repeal and replace all or part of the ACA. While Congress has not passed comprehensive repeal legislation, two bills affecting the implementation of certain taxes under the ACA have been signed into law. The Tax Cuts and Jobs Act of 2017 ("TCJA"), includes a provision repealing, effective January 1, 2019, the tax-based shared responsibility payment imposed by the ACA on certain individuals who fail to maintain qualifying health coverage for all or part of a year that is commonly referred to as the "individual mandate". Additionally, on January 22, 2018, President Trump signed a continuing resolution on appropriations for fiscal year 2018 that delayed the implementation of certain ACA-mandated fees, including the so-called "Cadillac" tax on certain high cost employer-sponsored insurance plans, the annual fee imposed on certain health insurance providers based on market share, and the medical device excise tax on non-exempt medical devices. Further, the Bipartisan Budget Act of 2018, or the BBA, among other things, amends the ACA, effective January 1, 2019, to close the coverage gap in most Medicare drug plans, commonly referred to as the "donut hole". In July 2018, CMS published a final rule permitting further collections and payments to and from certain ACA qualified health plans and health insurance issuers under the ACA risk adjustment program in response to the outcome of federal district court litigation regarding the method CMS uses to determine this risk adjustment. Congress may consider additional legislation to repeal or repeal and replace other elements of the ACA. More recently, the United States District Court for the Northern District of Texas struck down the ACA, deeming it unconstitutional given that Congress repealed the individual mandate in 2017. The decision has been stayed pending outcome of an appeal to the Fifth Circuit Court of Appeals. Although there is no immediate impact on the ACA, we will continue to evaluate the effect that the ACA and its possible repeal and replacement, or potential total revocation by the Supreme Court of the United States, has on our business.

In addition, other legislative changes have been proposed and adopted since the ACA was enacted. For example, in August 2011, the Budget Control Act of 2011, among other things, created measures for spending reductions by Congress. A Joint Select Committee on Deficit Reduction, tasked with recommending a targeted deficit reduction of at least $1.2 trillion for the years 2013 through 2021, was unable to reach required goals, thereby triggering the legislation's automatic reduction to several government programs. This includes aggregate reductions to Medicare payments to providers of up to 2.0% per fiscal year, which went into effect in 2013, and due to subsequent legislative amendments to the statute, including the BBA, will remain in effect through 2027 unless additional Congressional action is taken. In January 2013, then-President Barack Obama signed into law the American Taxpayer Relief Act of 2012 ("ATRA"), which, among others, delayed for another two months the budget cuts mandated by these sequestration provisions of the Budget Control Act of 2011. The ATRA also reduced Medicare payments to several providers, including hospitals, imaging centers and cancer treatment centers, and increased the statute of limitations period for the government to recover over-payments to providers from three to five years. Moreover, CMS has promulgated or amended a number of cost containment and value-based reimbursement measures in the ordinary course of business, and it is expected to continue revising its regulations and policies in response to market conditions and administration directives. These new laws may result in additional reductions in Medicare and other healthcare funding, which could have a material and adverse effect on our customers and accordingly, our financial operations.

42

Further, there has been increasing legislative and enforcement interest in the United States with respect to specialty drug pricing practices. Specifically, there have been several recent United States Congressional inquiries and proposed and enacted federal and state legislation designed to, among other things, bring more transparency to drug pricing, reduce the cost of prescription drugs under Medicare, review the relationship between pricing and manufacturer patient programs, and reform government program reimbursement methodologies for drugs. At the federal level, the Trump administration's budget proposal for fiscal year 2019 contains further drug price control measures that could be enacted during the 2019 budget process or in other future legislation, including, for example, measures to permit Medicare Part D plans to negotiate the price of certain drugs under Medicare Part B, to allow some states to negotiate drug prices under Medicaid, and to eliminate cost sharing for generic drugs for low-income patients. Additionally, on May 11, 2018, President Trump laid out his administration's "Blueprint" to lower drug prices and reduce out of pocket costs of drugs, as well as additional proposals to increase drug manufacturer competition, increase the negotiating power of certain federal healthcare programs, incentivize manufacturers to lower the list price of their products, and reduce the out of pocket costs of product candidates paid by consumers. Although most of these, and other, proposals will require authorization through additional legislation to become effective, the United States Congress and the Trump administration have each indicated that it will continue to seek new legislative and administrative measures to control drug costs, including by addressing the role of pharmacy benefit managers in the supply chain. HHS has already started the process of soliciting feedback on some of these measures and, at the same time, is immediately implementing others under its existing authority. For example, in September 2018, CMS announced that it will allow Medicare Advantage Plans to use step therapy for Part B drugs beginning January 1, 2019 in October 2018, CMS proposed a new rule that would require direct-to-consumer television advertisements of prescription drugs and biological products, for which payment is available through or under Medicare or Medicaid to include in the advertisement that Wholesale Acquisition Cost, or list price, of that drug or biological product and a February 6, 2019 proposed rule aims to eliminate certain Anti-Kickback safe harbor protections for drug rebates. At the state level, legislatures have increasingly passed legislation and implemented regulations designed to control pharmaceutical and biological product pricing, including price or patient reimbursement constraints, discounts, restrictions on certain product access and marketing cost disclosure and transparency measures, and, in some cases, designed to encourage importation from other countries and bulk purchasing.

More recently, on May 30, 2018, the Trickett Wendler, Frank Mongiello, Jordan McLinn, and Matthew Bellina Right to Try Act of 2017, or Right to Try Act, was signed into law. The law, among other things, provides a federal framework for patients to access certain investigational new product candidates that have completed a Phase I clinical trial. Under certain circumstances, eligible patients can seek treatment without enrolling in clinical trials and without obtaining FDA approval under the FDA expanded access program. The Right to Try Act did not establish any new entitlement or positive right to any party or individual, nor did it create any new mandates, directives, or additional regulations requiring a manufacturer or sponsor of an eligible investigational new product candidates to provide expanded access.

We are unable to predict the future course of federal or state healthcare legislation in the United States directed at broadening the availability of healthcare and containing or lowering the cost of healthcare. The United States Health Reform Laws and any further changes in the law or regulatory framework that reduce our revenue or increase our costs could also have a material and adverse effect on our business, financial condition and results of operations.

Healthcare laws and regulations may affect the pricing of our product candidates and may affect our profitability.

In certain countries, the government may provide healthcare at a subsidized cost to consumers and regulate prices, patient eligibility or third-party payor reimbursement policies to control the cost of product candidates. Such a system may lead to inconsistent pricing of our product candidates from one country to another. The availability of our product candidates at lower prices in certain countries may undermine our sales in other countries where our product candidates are more expensive. In addition, certain countries may set prices by reference to the prices of our product candidates in other countries. Our inability to secure adequate prices in a particular country may adversely affect our ability to obtain an acceptable price for our product candidates in existing and potential markets. If we are unable to obtain a price for our product candidates that provides an appropriate return on our investment, our profitability may be materially and adversely affected.

Our industry and we are subject to intense regulation from the United States Government and such other governments and quasi-official regulatory bodies where our products are and product candidates may be sold.

Both before and after regulatory approval to market a particular product candidate, including our biologic product candidates, the manufacturing, labeling, packaging, adverse event reporting, storage, advertising, promotion, distribution and record keeping related to the product are subject to extensive, ongoing regulatory requirements, including, without limitation, submissions of safety and other post-marketing information and reports, registration, as well as continued compliance with cGMP requirements and good clinical practice requirements for any clinical trials that we conduct post-approval. As a result, we are subject to a number of governmental and other regulatory risks, which include:

43

• clinical development is a long, expensive and uncertain process; delay and failure can occur at any stage of our clinical trials;

• our clinical trials are dependent on patient enrollment and regulatory approvals; we do not know whether our planned trials will begin on time, or at all, or will be completed on schedule, or at all;

• the FDA or other regulatory authorities may not approve a clinical trial protocol or may place a clinical trial on hold;

• we rely on third parties, such as consultants, contract research organizations, medical institutions, and clinical investigators, to conduct clinical trials for our drug candidates and if we or any of our third-party contractors fail to comply with applicable regulatory requirements, such as current Good Clinical Practices ("cGCP") requirements, the clinical data generated in our clinical trials may be deemed unreliable and the FDA, the European Medicines Agency ("EMA") or comparable foreign regulatory authorities may require us to perform additional clinical trials;

• if the clinical development process is completed successfully, our ability to derive revenues from the sale of therapeutics will depend on our first obtaining FDA or other comparable foreign regulatory approvals, each of which are subject to unique risks and uncertainties;

• there is no assurance that we will receive FDA or corollary foreign approval for any of our product candidates for any indication; we are subject to government regulation for the commercialization of our product candidates;

• we have not received regulatory approval in the United States for the commercial sale of any of our biologic product candidates;

• even if one or more of our product candidates does obtain approval, regulatory authorities may approve such product candidate for fewer or more limited indications than we request, may not approve the price we intend to charge for our products, may grant approval contingent on the performance of costly post-marketing clinical trials, or may approve with a label that does not include the labeling claims necessary or desirable for the successful commercialization of that product candidate;

• undesirable side effects caused by our product candidates could cause us or regulatory authorities to interrupt, delay or halt clinical trials and could result in a more restrictive label or the delay or denial of regulatory approval by the FDA or other comparable foreign authorities;

• later discovery of previously unknown problems with a product, including adverse events of unanticipated severity or frequency, or with our third-party manufacturers or manufacturing processes, or failure to comply with the regulatory requirements of FDA and other applicable United States and foreign regulatory authorities could subject us to administrative or judicially imposed sanctions;

• although several of our product candidates have received orphan drug designation in the United States and the EU for particular indications, we may not receive orphan drug exclusivity for any or all of those product candidates or indications upon approval, and even if we do obtain orphan drug exclusivity, that exclusivity may not effectively protect the product from competition; and

• even if one or more of our product candidates is approved in the United States, it may not obtain the 12 years of exclusivity from biosimilars for which innovator biologics are eligible, and even if it does obtain such exclusivity, that exclusivity may not effectively protect the product from competition; the FDA’s policies may change and additional government regulations may be enacted that could prevent, limit or delay regulatory approval of our drug candidates, and if we are slow or unable to adapt to changes in existing requirements or the adoption of new requirements or policies, or if we are not able to maintain regulatory compliance, we may lose any marketing approval that we may have obtained; and we may be liable for contamination or other harm caused by hazardous materials used in the operations of our business.

Healthcare providers, physicians and third-party payors often play a primary role in the recommendation and prescription of any currently marketed products and product candidates for which we may obtain marketing approval. Our current and future arrangements with healthcare providers, physicians, third-party payors and customers, and our sales, marketing and educational activities, may expose us to broadly applicable fraud and abuse and other healthcare laws and regulations (at the federal and state level) that may constrain our business or financial arrangements and relationships through which we market, sell and distribute

44

our products for which we obtain marketing approval. In addition, our operations are also subject to various federal and state fraud and abuse, physician payment transparency and privacy and security laws, including, without limitation:

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

• The federal civil and criminal false claims laws and civil monetary penalty laws, including the False Claims Act, which prohibits individuals or entities from, among other things, knowingly presenting, or causing to be presented, claims for payment to, or approval by, the federal government that are false, fictitious or fraudulent or knowingly making, using or causing to be made or used, a false record or statement material to a false or fraudulent claim to avoid, decrease or conceal an obligation to pay money to the federal government. As a result of a modification made by the Fraud Enforcement and Recovery Act of 2009, a claim includes "any request or demand" for money or property presented to the federal government. Although we do not submit claims directly to payors, manufacturers can be held liable under these laws if they are deemed to "cause" the submission of false or fraudulent claims by, for example, providing inaccurate billing or coding information to customers, promoting a product off-label, marketing products of sub-standard quality, or, as noted above, paying a kickback that results in a claim for items or services. In addition, our activities relating to the reporting of wholesaler or estimated retail prices for our products, the reporting of prices used to calculate Medicaid rebate information and other information affecting federal, state and third-party reimbursement for our products, and the sale and marketing of our products, are subject to scrutiny under this law. For example, several pharmaceutical and other healthcare companies have faced enforcement actions under these laws for allegedly inflating drug prices they report to pricing services, which in turn were used by the government to set Medicare and Medicaid reimbursement rates, and for allegedly providing free product to customers with the expectation that the customers would bill federal programs for the product. The False Claims Act also permits a private individual acting as a "whistleblower" to bring actions on behalf of the federal government alleging violations of the False Claims Act and to share in any monetary recovery. In addition, federal Anti-Kickback Statute violations and certain marketing practices, including off-label promotion, may also implicate the False Claims Act. Although the False Claims Act is a civil statute, conduct that results in a False Claims Act violation may also implicate various federal criminal statutes.

The federal Health Insurance Portability and Accountability Act of 1996, or HIPAA, which imposes criminal and civil liability for knowingly and willfully executing, or attempting to execute, a scheme to defraud or to obtain, by means of false or fraudulent pretenses, representations or promises, any money or property owned by, or under the control or custody of, any healthcare benefit program, including private third-party payors and knowingly and willfully falsifying, concealing or covering up by trick, scheme or device, a material fact or making any materially false, fictitious or fraudulent statement in connection with the delivery of or payment for healthcare benefits, items or services. Similar to the federal Anti-Kickback Statute, a person or entity does not need to have actual knowledge of the statute or specific intent to violate it to have committed a violation.

• HIPAA, as amended by the Health Information Technology for Economic and Clinical Health Act of 2009, or HITECH, and their respective implementing regulations, including the Final Omnibus Rule published on January 25, 2013, impose, among other things, obligations, including mandatory contractual terms, with respect to safeguarding the privacy, security and transmission of individually identifiable health information held by certain healthcare providers, health plans and

45

healthcare clearinghouses, known as covered entities, and business associates. Among other things, HITECH made certain aspects of HIPAA's rules (notably the Security Rule) directly applicable to business associates - independent contractors or agents of covered entities that receive or obtain individually identifiable health information in connection with providing a service on behalf of a covered entity. HITECH also created four new tiers of civil monetary penalties, amended HIPAA to make civil and criminal penalties directly applicable to business associates, and gave state attorneys general new authority to file civil actions for damages or injunctions in federal court to enforce the federal HIPAA laws and seek attorney's fees and costs associated with pursuing federal civil actions. The Department of Health and Human Services Office of Civil Rights, or the OCR, has increased its focus on compliance and continues to train state attorneys general for enforcement purposes. The OCR has recently increased both its efforts to audit HIPAA compliance and its level of enforcement, with one recent penalty exceeding $5 million.

• The federal physician payment transparency requirements, sometimes referred to as the "Physician Payments Sunshine Act," created under the United States Patient Protection and Affordable Care Act of 2010, as amended, or the ACA, and its implementing regulations, which requires applicable manufacturers of covered drugs, devices, biologics and medical supplies for which payment is available under Medicare, Medicaid or the State Children's Health Insurance Program (with certain exceptions) to annually report to the United States Department of Health and Human Services, or HHS, information related to certain payments or other transfers of value made or distributed to physicians (defined to include doctors, dentists, optometrists, podiatrists and chiropractors) and teaching hospitals, or to entities or individuals at the request of, or designated on behalf of, the physicians and teaching hospitals, as well as ownership and investment interests held by physicians and their immediate family members.

• On October 25, 2018, President Trump signed into law the “Substance Use-Disorder Prevention that Promoted Opioid Recovery and Treatment for Patients and Communities Act.” This law, in part (under a provision entitled “Fighting the Opioid Epidemic with Sunshine”), will extend the Sunshine Act to payments and transfers of value to physician assistants, nurse practitioners, and other mid-level healthcare providers (with reporting requirements going into effect in 2022 for payments made in 2021.

• According to the United States Federal Trade Commission, or the FTC, failing to take appropriate steps to keep consumers' personal information secure constitutes unfair acts or practices in or affecting commerce in violation of Section 5(a) of the Federal Trade Commission Act, or the FTCA, 15 USC § 45(a). The FTC expects a company's data security measures to be reasonable and appropriate in light of the sensitivity and volume of consumer information it holds, the size and complexity of its business, and the cost of available tools to improve security and reduce vulnerabilities. Medical data is considered sensitive data that merits stronger safeguards. The FTC's guidance for appropriately securing consumers' personal information is similar to what is required by the HIPAA Security Rule.

• Analogous state laws and regulations, such as state anti-kickback and false claims laws, which may apply to items or services reimbursed by any third-party payor, including commercial insurers, some state laws require pharmaceutical companies to comply with the pharmaceutical industry's voluntary compliance guidelines and the relevant compliance guidance promulgated by the federal government in addition to requiring drug manufacturers to report pricing and marketing information, including, among other things, information related to payments to physicians and other healthcare providers or marketing expenditures, state and local laws that require the registration of pharmaceutical sales representatives, and state laws governing the privacy and security of health information and the use of prescriber-identifiable data in certain circumstances, many of which differ from each other in significant ways and may not have the same effect, thus complicating compliance efforts.

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

If our operations are found to be in violation of any of the health regulatory laws described above or any other laws that apply to us, we may be subject to penalties, including, but not limited to, criminal, civil and administrative penalties, damages, fines, disgorgement, individual imprisonment, possible exclusion from participation in government healthcare programs, injunctions, private qui tam actions brought by individual whistleblowers in the name of the government and the curtailment or

46

restructuring of our operations, as well as additional reporting obligations and oversight if we become subject to a corporate integrity agreement or other agreement to resolve allegations of non-compliance with these laws, any of which could adversely affect our ability to operate our business and our results of operations.

Our failure to comply with data protection laws and regulations could lead to government enforcement actions and significant penalties against us, and adversely impact our operating results.

European Union member states and other foreign jurisdictions, including Switzerland, have adopted data protection laws and regulations which impose significant compliance obligations. Moreover, the collection and use of personal health data in the European Union, which was formerly governed by the provisions of the European Union Data Protection Directive, was replaced with the European Union General Data Protection Regulation, or the GDPR, in May 2018. The GDPR, which is wide-ranging in scope, imposes several requirements relating to the consent of the individuals to whom the personal data relates, the information provided to the individuals, the security and confidentiality of the personal data, data breach notification and the use of third party processors in connection with the processing of personal data. The GDPR also imposes strict rules on the transfer of personal data out of the European Union to the United States, provides an enforcement authority and imposes large penalties for noncompliance, including the potential for fines of up to €20 million or 4% of the annual global revenues of the non-compliant company, whichever is greater. The recent implementation of the GDPR has increased our responsibility and liability in relation to personal data that we process, including in clinical trials, and we may in the future be required to put in place additional mechanisms to ensure compliance with the GDPR, which could divert management's attention and increase our cost of doing business. In addition, new regulation or legislative actions regarding data privacy and security (together with applicable industry standards) may increase our costs of doing business. In this regard, we expect that there will continue to be new proposed laws, regulations and industry standards relating to privacy and data protection in the United States, the European Union and other jurisdictions, and we cannot determine the impact such future laws, regulations and standards may have on our business.

Our employees and our independent contractors, principal investigators, consultants or commercial collaborators, as well as their respective sub-contractors, if any, may engage in misconduct or fail to comply with certain regulatory standards and requirements, which could expose us to liability and adversely affect our reputation.

Our employees and our independent contractors, principal investigators, consultants or commercial collaborators, as well as their respective sub-contractors, if any, may engage in fraudulent conduct or other illegal activity, which may include intentional, reckless or negligent conduct that violates, among others, (a) FDA laws and regulations, or those of comparable regulatory authorities in other countries, including those laws that require the reporting of true, complete and accurate information to the FDA, (b) manufacturing standards, (c) healthcare fraud and abuse laws (d) anti-bribery and anti-corruption laws, including the FCPA, or (e) laws that require the true, complete and accurate reporting of financial information or data. For example, such persons may improperly use or misrepresent information obtained in the course of our clinical trials, create fraudulent data in our preclinical studies or clinical trials or misappropriate our drug products, which could result in regulatory sanctions being imposed on us and cause serious harm to our reputation. It is not always possible for us to identify or deter misconduct by our employees and third parties, and any precautions we may take to detect or prevent such misconduct may not be effective. Any misconduct or failure by our employees and our independent contractors, principal investigators, consultants or commercial collaborators, as well as their respective sub-contractors, if any, to comply with the applicable laws or regulations may expose us to governmental investigations, other regulatory action or lawsuits. If any action is instituted against us as a result of the alleged misconduct of our employees or other third parties, regardless of the final outcome, our reputation may be adversely affected and our business may suffer as a result. If we are unsuccessful in defending against any such action, we may also be liable to significant fines or other sanctions, which could have a material and adverse effect on us.

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

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

Disruptions at the FDA and other agencies may also slow the time necessary for new drugs to be reviewed and/or approved by necessary government agencies, which would adversely affect our business. For example, over the last several years, including

47

from December 22, 2018 until January 25, 2019, the U.S. government has shut down several times and certain regulatory agencies, such as the FDA and the SEC, have had to furlough critical FDA, SEC and other government employees and stop critical activities. If a prolonged government shutdown occurs, it could significantly impact the ability of the FDA to timely review and process our regulatory submissions, which could have a material adverse effect on our business. Further, in our operations as a public company, future government shutdowns could impact our ability to access the public markets and obtain necessary capital in order to properly capitalize and continue our operations.

Risks Related to Our Securities

Conversion of the Convertible Senior Notes will dilute the ownership interest of existing stockholders and could adversely affect the market price of our common stock.

The conversion of some or all of the Convertible Senior Notes will dilute the ownership interests of existing stockholders. Any sales in the public market of the common stock issuable upon such conversion and exercise could adversely affect prevailing market prices of our common stock. In addition, the existence of the Convertible Senior Notes may encourage short selling by market participants.

Our indebtedness and debt service obligations may adversely affect our cash flow.

We intend to fulfill our current debt service obligations, including repayment of the principal from our existing cash and investments, as well as the proceeds from potential licensing agreements and any additional financing from equity or debt transactions. However, our ability to make scheduled payments of the principal of, to pay interest on, or to refinance, our indebtedness, depends on our future performance, which is subject to economic, financial, competitive and other factors beyond our control. Our business may not generate cash flow from operations in the future sufficient to service our debt and make necessary capital expenditures. If we are unable to generate such cash flow to meet these obligations, we may be required to adopt one or more alternatives, such as selling assets, restructuring debt or obtaining additional equity capital on terms that may be onerous or highly dilutive, or delaying or curtailing research and development programs. Our ability to refinance our indebtedness will depend on the capital markets and our financial condition at such time. We may not be able to engage in any of these activities or engage in these activities on desirable terms, which could result in a default on our debt obligations.

We may add lease lines to finance capital expenditures and may obtain additional long‑term debt and lines of credit. If we issue other debt securities in the future, our debt service obligations will increase further.

Our indebtedness could have significant additional negative consequences, including, but not limited to:

• requiring the dedication of a substantial portion of our existing cash and marketable securities balances and, if available, future cash flow from operations to service our indebtedness, thereby reducing the amount of our expected cash flow available for other purposes, including capital expenditures;

• increasing our vulnerability to general adverse economic and industry conditions;

• limiting our ability to obtain additional financing;

• limiting our ability to sell assets if deemed necessary;

• limiting our flexibility in planning for, or reacting to, changes in our business and the industry in which we compete; and

• placing us at a possible competitive disadvantage to less leveraged competitors and competitors that have better access to capital resources.

We may not have the ability to raise funds necessary to purchase the Convertible Senior Notes upon a fundamental change and our future debt may contain limitations on our ability to repurchase the Convertible Senior Notes.

Following a fundamental change (which includes matters such as a change in control of the Company, approval by the Company’s stockholders of a plan of dissolution or liquidation of the Company, and the cessation of listing of the Company’s common stock on Nasdaq or The New York Stock Exchange, among others as further described in the indenture), holders of Convertible Senior Notes will have the right to require the Company to purchase their Convertible Senior Notes for cash. A fundamental change may also constitute an event of default or require prepayment under, and result in the acceleration of the

48

maturity of, our other then-existing indebtedness. We cannot assure you that we will have sufficient financial resources, or will be able to arrange financing, to pay the fundamental change purchase price in cash with respect to any Convertible Senior Notes surrendered by holders for purchase upon a fundamental change. In addition, restrictions in the agreements governing our then-outstanding indebtedness, if any, may not allow us to purchase the Convertible Senior Notes upon a fundamental change. Our failure to purchase the Convertible Senior Notes upon a fundamental change when required would result in an event of default with respect to the Convertible Senior Notes which could, in turn, constitute a default under the terms of our other indebtedness, if any. If the repayment of the related indebtedness were to be accelerated after any applicable notice or grace periods, we may not have sufficient funds to repay the indebtedness and purchase the Convertible Senior Notes, which could have a material and adverse impact on our financial condition and results of operations.

Shares eligible for future sale may adversely affect our ability to sell equity securities.

Sales of our common stock (including the issuance of shares upon conversion of convertible debt) in the public market could materially and adversely affect the market price of shares. As of September 30, 2019 we had 191,995,708 shares of common stock issued, plus (1) outstanding options to purchase 5,729,916 shares of common stock with a weighted-average exercise price of $16.36 per share, (2) 58,002 outstanding restricted stock units held by certain executive officers of the Company, (3) 694,569 outstanding performance stock options held by certain executive officers and employees of the Company, (4) 4,944,564 shares of common stock reserved for potential future grant under the Plan, and (5) $7.1 million of principal amount of Convertible Senior Notes convertible into approximately 1,393,160 shares of common stock at the conversion rate of $5.11 subject to adjustment as described in the indenture. Of the 250,000,000 shares of common stock authorized under our Certificate of Incorporation, there are 45,184,081 shares of common stock that remain available for future issuance.

Our outstanding Convertible Senior Notes, options and warrants may adversely affect our ability to consummate future equity‑based financings due to the dilution potential to future investors.

Due to the number of shares of common stock we are obligated to issue pursuant to outstanding Convertible Senior Notes, options and warrants, potential investors may not purchase our future equity offerings at market price because of the potential dilution such investors may suffer as a result of the exercise of the outstanding options and warrants or conversion of the outstanding Convertible Senior Notes.

The market price of our common stock has fluctuated widely in the past, and is likely to continue to fluctuate widely based on a number of factors, many of which are beyond our control.

The market price of our common stock has been, and is likely to continue to be, highly volatile. Furthermore, the stock market and the market for stocks of comparable biopharmaceutical companies like ours have from time to time experienced, and likely will again experience, significant price and volume fluctuations that are unrelated to actual operating performance.

From time to time, stock market analysts publish research reports or otherwise comment upon our business and future prospects. Due to a number of factors, we may fail to meet the expectations of securities analysts or investors and our stock price would likely decline as a result. These factors include:

• Announcements by us, any collaboration partners, any future alliance partners or our competitors of pre-clinical studies and clinical trial results, regulatory developments, technological innovations or new therapeutic products, product sales, new products or product candidates and product development timelines;

• The formation or termination of corporate alliances;

• Developments in patent or other proprietary rights by us or our respective competitors, including litigation;

• Developments or disputes concerning our patent or other proprietary rights, and the issuance of patents in our field of business to others;

• Government regulatory action;

• Period-to-period fluctuations in the results of our operations; and

• Developments and market conditions for emerging growth companies and biopharmaceutical companies, in general.

49

In addition, Internet “chat rooms” have provided forums where investors make predictions about our business and prospects, oftentimes without any real basis in fact, that readers may trade on.

In the past, following periods of volatility in the market prices of the securities of companies in our industry, securities class action litigation has often been instituted against those companies. Refer to “Legal Proceedings” for more information. If we face such litigation in the future, it would result in substantial costs and a diversion of management’s attention and resources, which could negatively impact our business.

Our principal stockholders can significantly influence all matters requiring the approval by our stockholders.

As of October 4, 2019, Avoro Capital Advisors LLC (“Avoro”) is the beneficial owner of approximately 11.6% of our outstanding common stock. Avoro is our largest stockholder, and Dr. Behzad Aghazadeh, the portfolio manager and controlling person of Avoro, serves as Chairman of our Board of Directors.

As a result of this voting power, Avoro has the ability to significantly influence the outcome of substantially all matters that may be put to a vote of our stockholders, including the election of our directors.

There are limitations on the liability of our directors, and we may have to indemnify our officers and directors in certain instances.

Our certificate of incorporation limits, to the maximum extent permitted under Delaware law, the personal liability of our directors for monetary damages for breach of their fiduciary duties as directors. Our bylaws provide that we will indemnify our officers and directors and may indemnify our employees and other agents to the fullest extent permitted by law. These provisions may be in some respects broader than the specific indemnification provisions under Delaware law. The indemnification provisions may require us, among other things, to indemnify such officers and directors against certain liabilities that may arise by reason of their status or service as directors or officers (other than liabilities arising from willful misconduct of a culpable nature), to advance their expenses incurred as a result of certain proceedings against them as to which they could be indemnified and to obtain directors’ and officers’ insurance. Section 145 of the Delaware General Corporation Law provides that a corporation may indemnify a director, officer, employee or agent made or threatened to be made a party to an action by reason of the fact that he or she was a director, officer, employee or agent of the corporation or was serving at the request of the corporation, against expenses actually and reasonably incurred in connection with such action if he or she acted in good faith and in a manner he or she reasonably believed to be in, or not opposed to, the best interests of the corporation, and, with respect to any criminal action or proceeding, had no reasonable cause to believe his or her conduct was unlawful. Delaware law does not permit a corporation to eliminate a director’s duty of care and the provisions of our certificate of incorporation have no effect on the availability of equitable remedies, such as injunction or rescission, for a director’s breach of the duty of care.

We believe that our limitation of officer and director liability assists us to attract and retain qualified employees and directors. However, in the event an officer, a director or the board of directors commits an act that may legally be indemnified under Delaware law, we will be responsible to pay for such officer(s) or director(s) legal defense and potentially any damages resulting there from. Furthermore, the limitation on director liability may reduce the likelihood of derivative litigation against directors and may discourage or deter stockholders from instituting litigation against directors for breach of their fiduciary duties, even though such an action, if successful, might benefit our stockholders and us. Given the difficult environment and potential for incurring liabilities currently facing directors of publicly-held corporations, we believe that director indemnification is in our and our stockholders’ best interests because it enhances our ability to attract and retain highly qualified directors and reduce a possible deterrent to entrepreneurial decision-making.

Nevertheless, limitations of director liability may be viewed as limiting the rights of stockholders, and the broad scope of the indemnification provisions contained in our certificate of incorporation and bylaws could result in increased expenses. Our board of directors believes, however, that these provisions will provide a better balancing of the legal obligations of, and protections for, directors and will contribute positively to the quality and stability of our corporate governance. Our board of directors has concluded that the benefit to stockholders of improved corporate governance outweighs any possible adverse effects on stockholders of reducing the exposure of directors to liability and broadened indemnification rights.

We are exposed to potential risks from legislation requiring companies to evaluate controls under Section 404 of the Sarbanes-Oxley Act.

The Sarbanes-Oxley Act requires that we maintain effective internal controls over financial reporting and disclosure controls and procedures. Among other things, we must perform system and process evaluation and testing of our internal controls

50

over financial reporting to allow management to report on, and our independent registered public accounting firm to attest to, our internal controls over financial reporting, as required by Section 404 of the Sarbanes-Oxley Act (“Section 404”). Compliance with Section 404 requires substantial accounting expense and significant management efforts. Our testing, or the subsequent review by our independent registered public accounting firm, may reveal deficiencies in our internal controls that would require us to remediate in a timely manner so as to be able to comply with the requirements of Section 404 each year. If we are not able to comply with the requirements of Section 404 in a timely manner each year, we could be subject to sanctions or investigations by the SEC, the Nasdaq Stock Market or other regulatory authorities that would require additional financial and management resources and could adversely affect the market price of our common stock.

We do not intend to pay dividends on our common stock. Until such time as we pay cash dividends, our stockholders, must rely on increases in our stock price for appreciation.

We have never declared or paid dividends on our common stock. We intend to retain future earnings to develop and commercialize our product candidates and therefore we do not intend to pay cash dividends in the foreseeable future. Until such time as we determine to pay cash dividends on our common stock, our stockholders must rely on increases in the market price of our common stock for appreciation of their investment.

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Business Overview, Basis of Presentation and Recent Accounting Pronouncements

Reference is made to the Transition Report on Form 10-K, of Immunomedics, Inc., a Delaware corporation (“Immunomedics,” the “Company,” “we,” “our” or “us”), for the six months ended December 31, 2018, which contains our audited consolidated financial statements and the notes thereto.

Business Overview, Basis of Presentation and Recent Accounting Pronouncements

Business Overview

Immunomedics, Inc., a Delaware corporation, together with its subsidiaries (collectively "we," "our," "us," "Immunomedics", or the "Company"), is a clinical-stage biopharmaceutical company that develops monoclonal antibody-based products for the targeted treatment of cancer. Immunomedics manages its operations as one line of business of researching, developing, manufacturing and marketing biopharmaceutical products, particularly antibody-based products for patients with difficult to treat solid tumor and blood cancers. The Company currently reports as a single industry segment with substantially all business conducted in the United States. Immunomedics conducts its research activities in the United States and runs its development studies in the United States and selected European countries. Our corporate objective is to become a fully-integrated biopharmaceutical company and a leader in the field of antibody-drug conjugates (“ADCs”). To that end, our immediate priority is to commercialize our most advanced ADC product candidate, sacituzumab govitecan ("IMMU-132"), beginning in the United States, with metastatic triple-negative breast cancer (“mTNBC”) as the first indication. On May 21, 2018, we submitted a Biologics License Application (“BLA”) to the United States Food and Drug Administration ("FDA") for sacituzumab govitecan for the treatment of patients with mTNBC who have received at least two prior therapies for metastatic disease. On July 18, 2018, we received notification from the FDA that the BLA was accepted for filing and the original application was granted Priority Review with a Prescription Drug User Fee Act ("PDUFA") target action date of January 18, 2019. On January 17, 2019, we received a Complete Response Letter ("CRL") from the FDA for the BLA. We subsequently met with the FDA on May 2, 2019 to review the FDA’s findings and discussed our BLA resubmission. Since then, we have developed a detailed plan to address the chemistry, manufacturing, and control (“CMC”) matters raised in the CRL and in our pre-approval inspection. We held another meeting with the FDA on September 27, 2019 to update the FDA on our progress in addressing these matters and to receive feedback from the FDA on our approach. We have dedicated, and continue to commit, significant resources to address the CMC matters identified by the FDA, while, in parallel, preparing our manufacturing facility to be ready for re-inspection by the FDA for acknowledgment of receipt of the submission.

Basis of Presentation

The accompanying unaudited condensed consolidated financial statements of Immunomedics, which incorporates our foreign subsidiary, Immunomedics GmbH in Rödermark, Germany, have been prepared in accordance with United States generally accepted accounting principles (“GAAP”), for interim financial information and the instructions to the Quarterly Report on Form 10‑Q and Regulation S‑X. Accordingly, the statements do not include all of the information and footnotes required by GAAP for complete annual financial statements. With respect to the financial information for the interim periods included in this Quarterly Report on Form 10-Q, which is unaudited, management believes that all adjustments (consisting of normal recurring accruals), considered necessary for a fair presentation of the results for such interim periods have been included. Operating results for the three and nine-month periods ended September 30, 2019, are not necessarily indicative of the results that may be expected for the full calendar year ending December 31, 2019, or any other period. The preparation of the condensed consolidated financial statements requires management to make estimates and assumptions that affect reported amounts and disclosures. Actual results could differ from those estimates.

Our significant accounting policies are described in Note 2 of Notes to Consolidated Financial Statements included in our 2018 Transition Report on Form 10-K. Such significant accounting policies are applicable for periods prior to the adoption of the following new accounting standards.

Recent Accounting Pronouncements

Accounting Pronouncements adopted during the year:

The Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2019-01, “Leases Topic 842,” requiring entities to recognize assets and liabilities on the balance sheet for all leases, with certain exceptions. Topic 842 allows for a modified retrospective application and is effective as of the first quarter of 2019. Entities are allowed to apply the new guidance using a modified retrospective approach at the beginning of the year in which new lease standard is adopted, rather than to the earliest comparative period presented in their financial statements. The modified retrospective approach includes a number of optional practical expedients that entities may elect to apply. We elected the modified retrospective approach under the new guidance and elected the available practical expedients on adoption. Upon adoption, we recognized additional operating lease liabilities of $8.4 million with a corresponding right-of-use assets of $8.4 million based on the present value of the remaining lease payments under existing operating leases. As of December 31, 2018, we had $2.1 million in deferred charges related to our real estate leases that were recorded against the lease liability asset as part of the transition, resulting in $10.5 million included in other long-term liabilities on our condensed consolidated balance sheet. In addition, the new guidance resulted in additional lease-related disclosures in the footnotes to our condensed consolidated financial statements. Our leasing portfolio is comprised entirely of operating leases, and we do not recognize right-of-use assets or related lease liabilities with a lease term of twelve months or less on our condensed consolidated balance sheet. Adoption of Topic 842 has required changes to our business processes and controls to comply with the provisions of the standard. Refer to Note 11 "Commitments and Contingencies" for additional information.

In June 2018, the FASB issued ASU 2018-07, "Compensation-Stock Compensation," to improve the usefulness of information provided to users of financial statements while reducing cost and complexity in financial reporting and provide guidance aligning the measurement and classification for share-based payments to nonemployees with the guidance for share-based payments to employees. Under the guidance, the measurement of equity-classified nonemployee awards will be fixed at the grant date. This standard is effective for fiscal years beginning after December 15, 2018, and interim periods within those annual periods. Early adoption is permitted, but no earlier than an entity's adoption date of ASU 2014-09, “Revenue from Contracts with Customers (Topic 606).” We adopted ASU 2018-07 during the first quarter of 2019 and the adoption did not have a material impact to our condensed consolidated financial statements.

Accounting Pronouncements yet to be adopted:

In November 2018, the FASB issued ASU 2018-18, "Collaborative Arrangements (Topic 808): Clarifying the Interaction between Topic 808 and Topic 606,"    to clarify when ASC 606 should be used for collaborative arrangements when the counterparty is a customer. The guidance precludes an entity from presenting consideration from a transaction in a collaborative arrangement as revenue from contracts with customers if the counterparty is not a customer for that transaction. The guidance is effective for public business entities in fiscal years beginning after December 15, 2019, and interim periods therein. Early adoption is permitted to entities that have adopted ASC 606. We are currently assessing the impact of ASU 2018-18.

In August 2018, the FASB issued ASU 2018-13, "Fair Value measurement (Topic 820): Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement," to no longer require public companies to disclose transfers between Level 1 and Level 2 of the fair value hierarchy, and to require disclosure about the range and weighted average used to develop significant unobservable inputs for Level 3 fair value measurements. The guidance is effective for fiscal years beginning after December 15, 2019, and for interim periods within those fiscal years. Entities are permitted to early adopt either the entire standard or only the provisions that eliminate or modify the requirements. We are currently assessing the impact of ASU 2018-13.

^(b) Level 2 - Financial instruments whose values are based on quoted market prices in markets where trading occurs infrequently or whose values are based on quoted prices of instruments with similar attributes in active markets.

^(c) Level 3 - Financial instruments whose values are based on prices or valuation techniques that require inputs that are both unobservable and significant to the overall fair value measurement. These inputs reflect management's own assumptions about the assumptions a market participant would use in pricing the asset.

^(d) The money market funds noted above are included in cash and cash equivalents.

Convertible Senior Notes

Convertible Senior Notes	$	7,093	$	18,900	$	7,055	$	20,100

The fair value of the Convertible Senior Notes, which differs from their carrying values, is influenced by interest rates, the Company’s stock price and stock price volatility, and is determined by prices for the Convertible Senior Notes observed in market trading which are Level 2 inputs.

Liability Related to the Sale of Future Royalties

The Company has determined the fair value of the liability related to the sale of future royalties is based on the Company's current estimates of future royalties expected to be paid to RPI, over the life of the arrangement, which are considered Level 3 (See Note 4 - "Debt").

There were no transfers between Level 1, Level 2, and Level 3 during the periods presented.

Collaboration Agreements

AstraZeneca/MedImmune

In June 2018, the Company entered into a clinical collaboration with AstraZeneca PLC ("AstraZeneca") and its global biologics research and development arm, MedImmune, to evaluate in Phase 1/2 studies the safety and efficacy of combining AstraZeneca’s Imfinzi^® (durvalumab), a human monoclonal antibody directed against programmed cell death ligand 1 ("PD-L1"), with sacituzumab govitecan as a treatment of patients with triple-negative breast cancer (“TNBC”) and urothelial cancer ("UC"), which was broadened in October 2018 to include second-line metastatic non-small cell lung cancer ("NSCLC").

Part one of the two-part Phase 1/2 studies will be co-funded by the two companies. Immunomedics will supply the study drug and AstraZeneca will utilize its existing clinical trial infrastructure to accelerate the enrollment of the sacituzumab govitecan and durvalumab combination. The trial design allows for rapid transition into randomized Phase 2 studies should the first part of these studies show promising data and the companies agree to proceed based on efficacy and safety results obtained.

The collaboration terminates thirty days following the expiration of the study periods end-date. Either party may terminate the collaboration earlier by providing thirty days' written notice.

GBG Forschungs GmbH

In September 2019, the Company entered into a clinical collaboration with GBG Forschungs-GmbH ("GBG"), Neu-Isenburg, Germany, to develop sacituzumab govitecan as a treatment for newly-diagnosed breast cancer patients who do not achieve a pathological complete response ("pCR") following standard neoadjuvant therapy.

The multinational, post-neoadjuvant Phase 3 SASCIA study developed by GBG will be conducted under the sponsorship of GBG. Approximately 1,200 high-risk patients with newly-diagnosed HER2-negative breast cancer not achieving a pCR following standard neoadjuvant therapy will be randomized to receive either sacituzumab govitecan or treatment of physician’s choice. Primary endpoint is invasive DFS with overall survival, patient reported outcome/quality of life, circulating tumor DNA clearance, and safety serving as secondary endpoints.

Under the terms of the agreement, GBG is eligible to receive up to €33.0 million in potential clinical and regulatory milestone payments over a span of approximately six years, of which €0.5 million to be paid at signing which is included in accrued expenses as of September 30, 2019. The collaboration terminates following the completion of the study or until either party terminates the collaboration earlier by providing thirty days' written notice.

Stockholders' Equity

Stockholders’ Equity

Common Stock 

On October 11, 2016, the Company completed an underwritten public offering of 10,000,000 shares of its common stock and accompanying warrants to purchase 10,000,000 shares of common stock at a purchase price of $3.00 per unit, comprising of one share of common stock and one warrant. The change in fair value of the warrant liabilities for the three and nine months ended September 30, 2018, resulted in a gain of $1.2 million and a loss of $47.8 million, respectively, which has been recognized in the accompanying condensed consolidated statements of comprehensive loss. During 2018, all of the warrants were exercised. As of September 30, 2019 and December 31, 2018, there were no warrants outstanding.

At-the-Market Offering

On March 29, 2019, the Company entered into a sales agreement (the "ATM Agreement") with Cowen and Company, LLC ("Cowen") to issue and sell shares of the Company’s common stock, par value $0.01 per share, having an aggregate offering price of up to $150.0 million, from time to time during the term of the ATM Agreement, through an “at-the-market” equity offering program at the Company's sole discretion, under which Cowen will act as the Company’s agent and/or principal. The Company will pay Cowen a commission up to 3.0% of the gross sales proceeds of any common stock sold through Cowen under the ATM Agreement. During the nine months ended September 30, 2019, the Company sold 370,920 shares of common stock with net proceeds of $5.8 million at a weighted average price of $15.95 (excluding commissions) under the ATM Agreement.

Commitments and Contingencies

a. Legal Matters

Stockholder Complaints:

Class Action Stockholder Federal Securities Cases

Two purported class action cases were filed in the United States District Court for the District of New Jersey; namely, Fergus v. Immunomedics, Inc., et al., filed June 9, 2016; and Becker v. Immunomedics, Inc., et al., filed June 10, 2016. These cases arise from the same alleged facts and circumstances and seek class certification on behalf of purchasers of our common stock between April 20, 2016 and June 2, 2016 (with respect to the Fergus matter) and between April 20, 2016 and June 3, 2016 (with respect to the Becker matter). These cases concern the Company’s statements in press releases, investor conference calls, and filings with the U.S. Securities and Exchange Commission (the "SEC") beginning in April 2016 that the Company would present updated information regarding its IMMU-132 breast cancer drug at the 2016 American Society of Clinical Oncology (“ASCO”) conference in Chicago, Illinois. The complaints allege that these statements were false and misleading in light of June 2, 2016 reports that ASCO had canceled the presentation because it contained previously reported information. The complaints further allege that these statements resulted in artificially inflated prices for our common stock, and that the Company and certain of its officers are thus liable under Sections 10(b) and 20(a) of the Securities Exchange Act of 1934, as amended (the "Exchange Act"). An order of voluntary dismissal without prejudice was entered on November 10, 2016 in the Becker matter. An order granting motion to consolidate cases, appoint lead plaintiff, and approve lead and liaison counsel was entered on February 7, 2017 in the Fergus matter. A consolidated complaint was filed on October 4, 2017. The Company filed a motion to dismiss the consolidated complaint on January 26, 2018. On March 31, 2019, the court granted the Company's motion to dismiss, without prejudice, and

left plaintiffs with the ability to file an amended complaint within thirty (30) days. Counsel for the Company has consented to an extension of time for plaintiffs to file the proposed amended complaint for an additional thirty (30) days. On May 30, 2019, plaintiffs filed an amended complaint alleging many of the same allegations that were set forth in the previously filed complaints, and the Company has filed a motion to dismiss.

A third purported class action case was filed in the United States District Court for the District of New Jersey; namely, Odeh v. Immunomedics, Inc., et al., filed December 27, 2018. The complaint in this action alleges that the Company failed to disclose the results of observations made by the FDA during an inspection of the Company’s manufacturing facility in Morris Plains, New Jersey in August 2018. The complaint alleges that Immunomedics misled investors by failing to disclose the Form 483 inspection report issued by the FDA which set forth the observations of the FDA inspector during the inspection. Such observations purportedly included, inter alia, manipulated bioburden samples, misrepresentation of an integrity test procedure in the batch record, and backdating of batch records. The complaint further alleges that the Company’s failure to disclose the Form 483 resulted in an artificially inflated price for our common stock, and that the Company and certain of its officers are thus liable under Sections 10(b) and 20(a) of the Exchange Act.

On February 8, 2019, a purported class action case was filed in the United States District Court for the District of New Jersey; namely, Choi v. Immunomedics, Inc., et al. The complaint asserts violations of the federal securities laws based on claims that the Company violated the federal securities laws by making alleged misstatements in various press releases and securities filings from February 8, 2018 to November 7, 2018 and by failing to disclose the substance of its interactions with the FDA in connection with the Company's submission of its BLA for sacituzumab govitecan. 

Motions for the appointment of a lead plaintiff and lead counsel and to consolidate the Odeh and Choi actions were granted on September 10, 2019. Pursuant to a scheduling order entered by the court on October 7, 2019, the plaintiffs must file an amended complaint by November 18, 2019.

On April 8, 2019, a putative stockholder of the Company filed a derivative action purportedly on behalf of the Company and against the Company’s board of directors and certain Company current and former officers, in the Superior Court of New Jersey, Law Division (Morris County); namely, Crow v. Aghazadeh, et al. The Crow complaint alleges that the individual defendants breached their fiduciary duties and committed other violations of law based on the same core allegations in the Odeh and Choi actions. The Crow complaint was served on the Company and other defendants on July 18, 2019. On August 13, 2019, the parties submitted to the court a stipulation and proposed order to stay the action until either the entry of an order denying all motions to dismiss the now-consolidated federal actions or the entry of an order dismissing the federal actions with prejudice. That stipulation is currently pending court approval.

Stockholder Claim in the Court of Chancery of the State of Delaware

On February 13, 2017, venBio commenced an action captioned venBio Select Advisor LLC v. Goldenberg, et al., C.A. (Del. Ch.) (the “venBio Action”), alleging that Company’s Board breached their fiduciary duties when the Board (i) amended the Company’s Amended and Restated By-laws (the “By-Laws”) to call for a plurality voting regime for the election of directors instead of majority voting, and providing for mandatory advancement of attorneys’ fees and costs for the Company’s directors and officers, (ii) rescheduled the Company’s 2016 Annual Meeting of Stockholders (the “2016 Annual Meeting”) from December 14, 2016 to February 16, 2017, and then again to March 3, 2017, and (iii) agreed to the proposed Licensing Transaction with Seattle Genetics. venBio also named Seattle Genetics as a defendant and sought an injunction preventing the Company from closing the licensing transaction with Seattle Genetics. On March 6, 2017, venBio amended its complaint, adding further allegations. The Court of Chancery entered a temporary restraining order on March 9, 2017, enjoining the closing of the Licensing Transaction. venBio amended its complaint a second time on April 19, 2017, this time adding Greenhill & Co. Inc. and Greenhill & Co. LLC (together “Greenhill”), the Company’s financial advisor on the Licensing Transaction, as an additional defendant. On May 3, 2017, venBio and the Company and individual defendants Dr. Goldenberg, Ms. Sullivan and Mr. Brian A. Markison, a director of the Company (collectively, the “Individual Defendants”) entered into the Initial Term Sheet. On June 8, 2017, venBio the Company and Greenhill entered into the Greenhill Term Sheet. On February 9, 2018, the Court of Chancery approved the Settlement, and entered an order and partial judgment releasing all claims that were asserted by venBio against the Individual Defendants and Greenhill in the venBio Action and awarding venBio fees and expenses. On May 24, 2018 the remaining parties to the venBio Action participated in a mediation of the claims against Geoff Cox, Robert Forrester, Bob Oliver, and Jason Aryeh (the "Remaining Defendants"). The mediation was unsuccessful. The Remaining Defendants filed submitted motions to dismiss the claims against them in the venBio Action. On March 18, 2019, venBio amended its complaint, adding further allegations. The Remaining Defendants filed a motion to dismiss the claims against them on May 1, 2019. The Court of Chancery has scheduled oral arguments for the motion to dismiss on November 13, 2019.

Insurance Coverage Arbitration:

The Company has initiated an arbitration with two of its management liability insurers: Starr Indemnity & Liability Company (“Starr”), and Liberty Insurance Underwriters Inc. (“Liberty”) (collectively, “Insurers”).  The arbitration arises from the 2015 Insurers’ refusal to cover $3,402,980 in attorneys’ fees and expenses paid to venBio pursuant to a December 1, 2017, settlement agreement between venBio, the Company, Dr. Goldenberg, Ms. Sullivan, Mr. Markison, and Greenhill to partially settle the venBio Action and fully settle the Federal Action and the Delaware Section 225 Action (the “venBio Fee Award”).  

The Insurers argue that the venBio Fee Award does not satisfy their policies’ definitions of covered “loss” because the policies only cover defense costs incurred by the Company.  The Company counters that the venBio Fee Award is a covered settlement, not a claim for defense costs.  Insurers also argue that they have no obligation to pay any defense costs or settlement incurred in the Federal Action or 225 Action because Immunomedics initiated those lawsuits.  The Company’s position is that the Federal Action and 225 Action were defensive in nature and therefore covered because they were initiated to further the defense of the venBio Action.  Additionally, Insurers argue the venBio Fee Award is not covered because the Company was required to obtain Insurers’ consent to enter into a binding term sheet in the venBio Action and to agree to pay the venBio Fee Award and that the Company failed to do so.  The Company takes the position that Insurers at all times were aware of the developments in the venBio Action, that they sought consent to enter into the settlement, and that Insurers cannot show they were prejudiced by an any alleged failure to obtain Insurers’ consent.

Liberty also contends that the Company’s insurance claim is not covered by Liberty’s 2015-16 insurance policy and should be covered by another company’s policy in a later policy period. The Company takes the position that the policies treat the venBio Action as a related claim to the Fergus v. Immunomedics class action stockholder federal securities case, which was filed in 2016 and that because of the similar allegation in the venBio Action and Fergus, the policies deem the venBio Action claim to be made at the same time as Fergus and covered by the 2015-16 policies. In the arbitration, Starr contends it will have the benefit of any finding that the claim is covered in a later policy period, even though Starr had agreed with the Company’s position prior to the arbitration.

In the event Insurers prevail on their argument that the venBio Fee Award is covered by a subsequent policy year, the Company will pursue coverage under its other insurance policies.

Starr is presently advancing the costs to defend the remaining claims in the venBio Action, i.e., those against the Company as Nominal Defendant and individual defendants Aryeh, Cox, Forrester, and Oliver.  However, all Insurers have reserved their rights to contest coverage for any potential settlement of those claims.

Breach of Contract:

On November 16, 2018, Kapil Dhingra filed a complaint against Immunomedics, Inc., in the Superior Court of New Jersey, Law Division, Morris County, alleging breach of contract and breach of the implied covenant of good faith and fair dealing. In the complaint, Dhingra alleges that Immunomedics breached agreements with Dhingra entered into in 2012 and 2013 that purportedly give him the right to purchase 50,000 shares of Common Stock of Immunomedics for a strike price stated in the agreements. On January 11, 2019, Immunomedics filed a motion for summary judgment and to stay discovery while the motion for summary judgment was pending. On February 5, 2019, Dhingra filed an opposition brief and an amended complaint adding as a plaintiff Kapital Consulting, LLC (together with Dhingra, "Plaintiffs"), and Plaintiffs filed a partial cross-motion for summary judgment. On April 4, 2019, the Court denied all motions without prejudice pending the completion of discovery. Immunomedics continues to dispute the allegations and will seek expedited disposition following discovery.

b. Other Matters:

Immunomedics is also a party to various claims and litigation arising in the normal course of business.

c. Our Licenses

We have obtained licenses from various parties for rights to use, develop and commercialize proprietary technologies and compounds. Currently, we have the following licenses:

Medical Research Council (“MRC”) - We entered into a license agreement with MRC in May 1994, whereby we have obtained a license for certain patent rights with respect to the genetic engineering on monoclonal antibodies. Our agreement does not require any milestone payments, nor have we made any payments to MRC to date. Our agreement with MRC, which expires

at the expiration of the last of the licensed patents in 2020, provides for future royalty payments in the low single digits based on a percentage of product sales.

On April 4, 2018, we entered into a license agreement with The Scripps Research Institute ("TSRI"). Pursuant to the license agreement, TSRI granted to us an exclusive, worldwide, sub-licensable, royalty-bearing license to use certain patent rights relating to sacituzumab govitecan. The license agreement expires on a country-by-country basis on the expiration date of the last to expire licensed patent rights in such country covering a licensed product. The license agreement may be terminated by the mutual written consent of us and TSRI, and TSRI may terminate the license agreement upon the occurrence of certain events, including, but not limited to if we do not make a payment due pursuant to the license agreement and fail to cure such non-payment within 30 days after the date of TSRI's written notice of such non-payment. As consideration for the license granted, we made a cash payment of $250,000 to TSRI. Additionally, we will pay TRSI (i) product development milestone payments that range from the mid six-digit dollar figure to the low seven-digit dollar figure and (ii) royalties on net sales of licensed products in the low-single digit percentage figure range capped at an annual amount. We have agreed to use reasonable efforts to develop and market the licensed products.

d. Michael Pehl Separation

On March 13, 2019, the Company entered into a separation agreement (the “Separation Agreement”) with Michael Pehl, the Company’s former Chief Executive Officer, President and member of the Company’s Board. Mr. Pehl resigned as Chief Executive Officer, President and member of the Company’s Board effective February 23, 2019. Pursuant to the Separation Agreement, Mr. Pehl will receive cash payments of approximately $1.0 million over an eighteen-month period. During the nine months ended September 30, 2019, the Company paid approximately $0.3 million to Mr. Pehl, and $0.7 million was accrued for as of September 30, 2019. Mr. Pehl also released the Company from any and all claims with respect to all matters arising out of or related to Mr. Pehl’s employment by the Company and his resignation.

e. Leases

Our operating lease assets primarily represent manufacturing and research and development facilities, warehouses, and offices. Our finance leases primarily represent computer equipment and are not significant. Total operating lease expense was $0.3 million for the three months ended September 30, 2019, and $1.0 million for the nine months ended September 30, 2019. For the three and nine months ended September 30, 2019, cash payments against operating lease liabilities totaled $0.3 million and $1.0 million, respectively. The discount rate used to determine the net present value of the leases at inception was 11.0%. This is the incremental borrowing rate that represents the rate of interest that the Company would expect to pay to borrow an amount equal to the lease payments under similar terms. Our leases both share a remaining lease term of 12.1 years, some of which may include options to extend the leases further. The Company considers these options in determining the lease term used to establish the right-of-use assets and lease liabilities.

Revenue from Contract with Customer [Abstract]

Revenue Recognition

Revenue Recognition

Pursuant to Topic 606, we recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. To achieve this core principle, Topic 606 includes provisions within a five step model that includes i) identifying the contract with a customer, ii) identifying the performance obligations in the contract, iii) determining the transaction price, iv) allocating the transaction price to the performance obligations, and v) recognizing revenue when, or as, an entity satisfies a performance obligation.

At contract inception, we assess the goods or services promised within each contract and assess whether each promised good or service is distinct and determine those that are performance obligations. We then recognize as revenue the amount of the transaction price that is allocated to the respective performance obligation when the performance obligation is satisfied.

Everest Medicines II Limited:

On April 29, 2019, the Company entered into a license agreement (the “License Agreement”) with Everest Medicines II Limited, a China limited company (“Everest”). Pursuant to the License Agreement, the Company granted Everest an exclusive license to develop and commercialize sacituzumab govitecan in the People’s Republic of China, Taiwan, Hong Kong, Macao, Indonesia, Philippines, Vietnam, Thailand, South Korea, Malaysia, Singapore and Mongolia (the "Territory"). In consideration for entering into the License Agreement, Everest made a one-time, non-refundable upfront payment to the Company in the aggregate amount of $65.0 million which is recorded as deferred revenue. The License Agreement contains a development milestone payment of $60.0 million based upon the Company’s achievement of FDA approval for sacituzumab govitecan in mTNBC. The License Agreement also contains additional development milestone payments in a total amount of up to $180.0 million based upon the achievement of certain other development milestones. In addition, the License Agreement contains sales milestone payments in a total amount of up to $530.0 million based upon the achievement of certain sales milestones. Everest will make royalty payments to the Company based upon percentages of net sales of sacituzumab govitecan, ranging from 14% to 20%.

The Company assessed the arrangement in accordance with ASC 606 and concluded that the contract counterparty, Everest, is a customer based on the arrangement structure. The Company identified two material promises to deliver under the contract: (1) grant of license and the (2) clinical and commercial supply of the product. However, given the nature of the manufacturing of the product the license is not considered to be distinct from the clinical and commercial supply promise. The Company therefore concluded that there is one combined performance obligation.

The Company initially deferred and will recognize the $65.0 million over the performance obligation period of the combined performance obligation. As it relates to the upfront consideration, the $65.0 million is recorded as deferred revenue and will be recognized over the term of the of the contract performance obligation period, which the Company has concluded to be 15 years after initial sale of the product in the territory. As concluded above, the Company has a combined performance obligation, which includes delivering the license and clinical and commercial supply to Everest. As such, because the clinical and commercial supply obligation occur throughout the period of the License Agreement, the $65.0 million fixed consideration is recognized over the period in which commercial and clinical supply of product is delivered (over-time).

The future potential milestone payments are excluded from the transaction price, as the achievement of the milestone events require considerable judgment in determining whether it is probable of being achieved, and that a significant revenue reversal would not occur. As such, all milestone payments are fully constrained. The Company will reevaluate the transaction price at the end of each reporting period and as uncertain events are resolved or other changes in circumstances occur, and, if necessary, adjust its estimate of the transaction price.

Janssen Biotech Inc.:

On April 5, 2019, the Company entered into a promotion agreement (the “Promotion Agreement”) with Janssen Biotech Inc., ("Janssen") pursuant to which the Company will provide non-exclusive product detailing services to Janssen for erdafitinib (the “Product”). Pursuant to the Promotion Agreement, the Company will provide a dedicated sales team to market the Product, upon approval by the FDA, to oncologists and other targeted health care providers in the United States. Under the terms of the Promotion Agreement, Janssen maintains ownership of the New Drug Application for the Product as well as legal, regulatory, distribution, commercialization and manufacturing responsibilities for the Product, while the Company will provide product detailing services to Janssen.  Following the achievement of certain sales targets in 2019 and 2020, Janssen will pay the Company (a) a service fee equal to a percentage in the low double digits of the portion of Cumulative Net Sales (as defined in the Promotion Agreement) in excess of a baseline amount during each of 2019 and 2020, and (b) potential milestone payments of up to $15.0 million when Cumulative Net Sales exceed certain thresholds during each of 2019 and 2020. On April 12, 2019, the Company

was informed that the FDA granted accelerated approval to Janssen's Balversa (erdafitinib) for the treatment of adult patients with locally advanced or metastatic urothelial carcinoma that has a type of susceptible genetic alteration known as FGFR3 or FGFR2, and that has progressed during or following prior platinum-containing chemotherapy. During the three and nine months ended September 30, 2019, no revenues were recorded relating to the Promotion Agreement.

On January 8, 2018, Morris Rosenberg joined the Company as Chief Technology Officer and became a full-time employee. Between May 5, 2017 and January 7, 2018, Mr. Rosenberg was engaged by the Company as an independent consultant pursuant to a consulting agreement between the Company and Mr. Rosenberg’s consulting company, M Rosenberg BioPharma Consulting LLC. The Company paid M Rosenberg BioPharma Consulting LLC $0.6 million during this time and Morris Rosenberg was also granted stock options to purchase 45,000 shares of the Company's common stock pursuant to the Immunomedics, Inc. 2014 Long-Term Incentive Plan. From January 8, 2018 through September 30, 2018, the Company paid M Rosenberg BioPharma $0.8 million for services agreed upon prior to Mr. Rosenberg becoming a full-time employee. As part of his employment contract, 50% of the 45,000 shares granted to Mr. Rosenberg as a consultant were forfeited, and the remaining 50% continue to vest. Mr. Rosenberg received 104,389 stock options and was permitted to continue to provide certain limited outside consulting services through M Rosenberg BioPharma Consulting LLC based on certain restrictions outlined in the contract. Additionally, during his employment period, except with the prior written consent of the Company's Board of Directors (the "Board"), Mr. Rosenberg is not permitted to enter into any contract, agreement or other transaction arrangement to provide goods and/or services to the Company through M Rosenberg BioPharma Consulting LLC.

Debt Disclosure [Abstract]

Debt

Liability Related to Sale of Future Royalties:

On January 7, 2018, the Company entered into a funding agreement with RPI Finance Trust, a Delaware statutory trust ("RPI"), under which we sold a portion of our right to receive royalties on potential net sales of the ADC sacituzumab govitecan, in exchange for $175.0 million in cash. Concurrently, we entered into a common stock purchase agreement with RPI through which RPI purchased 4.4 million shares of the Company's common stock for $75.0 million (the "Financing").

The Company concluded that there were two units of accounting in the transaction: (1) the liability related to the sale of future royalties (the "Liability") and (2) the "Financing". We allocated the consideration of $250.0 million on a relative fair value basis to the Liability for $182.2 million and the common stock for $67.8 million. We continue to accrete the Liability related to the sale of future royalties using the effective interest method with an annual interest rate of approximately 16% over a period of 20 years. As of September 30, 2019 and December 31, 2018, we determined the fair value at $251.3 million and $221.3 million, respectively. During the three months ended September 30, 2019 and 2018, the Company recognized approximately $9.6 million and $9.8 million in interest expense, respectively. During the nine months ended September 30, 2019 and 2018, the Company recognized approximately $30.0 million and $29.6 million in interest expense, respectively.

The following table shows the activity within the liability related to sale of future royalties during the nine months ended September 30, 2019 (in thousands):

Carrying value of liability related to sale of future royalties at December 31, 2018	$	221,295
Interest expense recognized	30,022
Carrying value of liability related to sale of future royalties at September 30, 2019	$	251,317

Convertible Senior Notes:

In February 2015, the Company issued $100.0 million of Convertible Senior Notes (the "Convertible Senior Notes") (net proceeds of approximately $96.3 million after deducting the initial purchasers’ fees and offering expenses) in a private offering exempt from registration under the Securities Act of 1933, as amended (the “Securities Act”), in reliance upon Rule 144A under the Securities Act. The Convertible Senior Notes will mature on February 15, 2020, unless earlier purchased or converted. The debt issuance costs of approximately $3.7 million, primarily consisting of underwriting, legal and other professional fees, are amortized over the term of the Convertible Senior Notes. The Convertible Senior Notes are senior unsecured obligations of the Company. Interest at 4.75% is payable semiannually on February 15 and August 15 of each year. The effective interest rate on the Convertible Senior Notes was 5.48% for the period from the date of issuance through September 30, 2019. The balance of the outstanding Convertible Senior Notes was $7.1 million convertible into 1.4 million shares of common stock at September 30, 2019, and December 31, 2018.

If the Company undergoes a fundamental change (as defined in the indenture governing the Convertible Senior Notes), holders may require Immunomedics to purchase for cash all or part of the Convertible Senior Notes at a purchase price equal to 100% of the principal amount of the Convertible Senior Notes to be purchased, plus accrued and unpaid interest, if any, to, but excluding, the fundamental change purchase date, subject to certain exceptions. In addition, if certain make-whole fundamental changes (as defined in the indenture governing the Convertible Senior Notes) occur, Immunomedics will, in certain circumstances, increase the conversion rate for any Convertible Note converted in connection with such make-whole fundamental change.

Total interest expense for the Convertible Senior Notes for the three months ended September 30, 2019 and 2018 was $0.1 million and $0.2 million, respectively. For the nine months ended September 30, 2019 and 2018, interest expense was $0.3 million and $0.7 million, respectively. Included in interest expense was an immaterial amount of amortization of debt issuance costs for the three and nine months ended September 30, 2019 and 2018.

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Basis of Accounting

Basis of Presentation

The accompanying unaudited condensed consolidated financial statements of Immunomedics, which incorporates our foreign subsidiary, Immunomedics GmbH in Rödermark, Germany, have been prepared in accordance with United States generally accepted accounting principles (“GAAP”), for interim financial information and the instructions to the Quarterly Report on Form 10‑Q and Regulation S‑X. Accordingly, the statements do not include all of the information and footnotes required by GAAP for complete annual financial statements. With respect to the financial information for the interim periods included in this Quarterly Report on Form 10-Q, which is unaudited, management believes that all adjustments (consisting of normal recurring accruals), considered necessary for a fair presentation of the results for such interim periods have been included. Operating results for the three and nine-month periods ended September 30, 2019, are not necessarily indicative of the results that may be expected for the full calendar year ending December 31, 2019, or any other period. The preparation of the condensed consolidated financial statements requires management to make estimates and assumptions that affect reported amounts and disclosures. Actual results could differ from those estimates.

Our significant accounting policies are described in Note 2 of Notes to Consolidated Financial Statements included in our 2018 Transition Report on Form 10-K. Such significant accounting policies are applicable for periods prior to the adoption of the following new accounting standards.

Recent Accounting Pronouncements

Recent Accounting Pronouncements

Accounting Pronouncements adopted during the year:

The Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2019-01, “Leases Topic 842,” requiring entities to recognize assets and liabilities on the balance sheet for all leases, with certain exceptions. Topic 842 allows for a modified retrospective application and is effective as of the first quarter of 2019. Entities are allowed to apply the new guidance using a modified retrospective approach at the beginning of the year in which new lease standard is adopted, rather than to the earliest comparative period presented in their financial statements. The modified retrospective approach includes a number of optional practical expedients that entities may elect to apply. We elected the modified retrospective approach under the new guidance and elected the available practical expedients on adoption. Upon adoption, we recognized additional operating lease liabilities of $8.4 million with a corresponding right-of-use assets of $8.4 million based on the present value of the remaining lease payments under existing operating leases. As of December 31, 2018, we had $2.1 million in deferred charges related to our real estate leases that were recorded against the lease liability asset as part of the transition, resulting in $10.5 million included in other long-term liabilities on our condensed consolidated balance sheet. In addition, the new guidance resulted in additional lease-related disclosures in the footnotes to our condensed consolidated financial statements. Our leasing portfolio is comprised entirely of operating leases, and we do not recognize right-of-use assets or related lease liabilities with a lease term of twelve months or less on our condensed consolidated balance sheet. Adoption of Topic 842 has required changes to our business processes and controls to comply with the provisions of the standard. Refer to Note 11 "Commitments and Contingencies" for additional information.

In June 2018, the FASB issued ASU 2018-07, "Compensation-Stock Compensation," to improve the usefulness of information provided to users of financial statements while reducing cost and complexity in financial reporting and provide guidance aligning the measurement and classification for share-based payments to nonemployees with the guidance for share-based payments to employees. Under the guidance, the measurement of equity-classified nonemployee awards will be fixed at the grant date. This standard is effective for fiscal years beginning after December 15, 2018, and interim periods within those annual periods. Early adoption is permitted, but no earlier than an entity's adoption date of ASU 2014-09, “Revenue from Contracts with Customers (Topic 606).” We adopted ASU 2018-07 during the first quarter of 2019 and the adoption did not have a material impact to our condensed consolidated financial statements.

Accounting Pronouncements yet to be adopted:

In November 2018, the FASB issued ASU 2018-18, "Collaborative Arrangements (Topic 808): Clarifying the Interaction between Topic 808 and Topic 606,"    to clarify when ASC 606 should be used for collaborative arrangements when the counterparty is a customer. The guidance precludes an entity from presenting consideration from a transaction in a collaborative arrangement as revenue from contracts with customers if the counterparty is not a customer for that transaction. The guidance is effective for public business entities in fiscal years beginning after December 15, 2019, and interim periods therein. Early adoption is permitted to entities that have adopted ASC 606. We are currently assessing the impact of ASU 2018-18.

In August 2018, the FASB issued ASU 2018-13, "Fair Value measurement (Topic 820): Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement," to no longer require public companies to disclose transfers between Level 1 and Level 2 of the fair value hierarchy, and to require disclosure about the range and weighted average used to develop significant unobservable inputs for Level 3 fair value measurements. The guidance is effective for fiscal years beginning after December 15, 2019, and for interim periods within those fiscal years. Entities are permitted to early adopt either the entire standard or only the provisions that eliminate or modify the requirements. We are currently assessing the impact of ASU 2018-13.
