Material Agreements	Material Agreements Purchase and Sale Agreement with RTW Investments LP On August 13, 2025, the Company entered into the Purchase Agreement with funds managed by RTW Investments LP. Under the terms of the Purchase Agreement, in exchange for the Purchaser's payment to the Company of a purchase price of $75,000, upon approval of Anaphylm by the FDA by a specified date, the refinancing of the Company’s existing 13.5% Notes and certain other customary conditions (the "Closing Conditions"), the Company agreed to a sale of assigned interests to the Purchaser, including a right for the Purchaser to tiered revenue share payments ranging from 1.0% to 7.5% of net sales (as defined in the Purchase Agreement) of Anaphylm (and 9.5% for the subsequent calendar year period if net sales do not achieve specified level in a calendar year period beginning in 2027) in the United States. Revenue share payments commence in the first fiscal quarter in which the first commercial sale of Anaphylm in the United States after the satisfaction of the Closing Conditions. Revenue share payments will cease upon the Purchaser's receipt of $187,500 by December 31, 2035 or $225,000 thereafter. The Purchase Agreement contains customary affirmative and negative covenants, including covenants that limit or restrict the Company’s ability to, among other things, incur indebtedness (which restrictions are eliminated after the achievement by the Purchaser of a specified return on its investment), and other provisions customary for transactions of this nature, in each case subject to certain exceptions set forth in the Purchase Agreement. As this financing is contingent on events that have not occurred yet and are outside of the Company's control, the accounting consequences for this transaction as of March 31, 2026 and December 31, 2025 have been limited to capitalized legal fees of approximately $750 and $700, respectively, recorded within Other current assets on the Condensed Balance Sheets. On March 3, 2026, the Company entered into the Amendment No. 1 to the Purchase Agreement. The Amendment extends the Marketing Approval Deadline from its original date in the Purchase Agreement to June 30, 2027. Concurrently, the Company entered into a Warrant Issuance Agreement with funds managed by RTW, pursuant to which the Company agreed to issue a warrant to purchase up to 375,000 shares of the Company's Common Stock at an exercise price of $4.00 per share, expiring on March 3, 2029. For information regarding the RTW Warrants, see Note 14, Warrants. On March 3, 2026, the Company also entered into a Share Purchase Commitment Agreement with certain RTW-affiliated funds, pursuant to which such funds committed to purchase, in the aggregate, not less than $5,000 of Common Stock during the 90-day period following the effective date of the Amendment, at prices determined in accordance with Rule 415(a)(4) under the Securities Act. Commercial Exploitation Agreement with Indivior In August 2008, the Company entered into the Indivior License Agreement (with subsequent amendments) with Reckitt Benckiser Pharmaceuticals, Inc. who was later succeeded to in interest by Indivior. Pursuant to the Indivior License Agreement, the Company agreed to manufacture and supply Indivior’s requirements for Suboxone®, a sublingual film formulation, both inside and outside the United States on an exclusive basis. Under the terms of the Indivior License Agreement, the Company is required to manufacture Suboxone in accordance with current Good Manufacturing Practice standards and according to the specifications and processes set forth in the related quality agreements the Company entered into with Indivior. Additionally, the Company is required to obtain API for the manufacture of Suboxone directly from Indivior. The Indivior License Agreement specifies a minimum annual threshold quantity of Suboxone that the Company is obligated to fill and requires Indivior to provide the Company with a forecast of its requirements at various specified times throughout the year. The Indivior License Agreement provides for payment by Indivior of an agreed upon purchase price per unit until January 1, 2025 and, thereafter, that is subject to annual adjustments based on changes in an agreed upon price index. In addition to the purchase price for the Suboxone supplied, Indivior is required to make certain single digit percentage royalty payments tied to net sales value (as provided for in the Indivior License Agreement) outside of the U.S., subject to annual maximum amounts and limited to the life of the related patents. The Indivior License Agreement contains customary contractual termination provisions, including with respect to a filing for bankruptcy or corporate dissolution, an invalidation of the intellectual property surrounding Suboxone, and commission of a material breach of the Indivior License Agreement by either party. Additionally, Indivior may terminate the Indivior License Agreement if the FDA or other applicable regulatory authority declares the Company’s manufacturing site to no longer be suitable for the manufacture of Suboxone or Suboxone is no longer suitable to be manufactured due to health or safety reasons. The initial term of the Indivior License Agreement was seven years from the commencement date. Thereafter, the Indivior License Agreement automatically renewed for successive one-year periods. Effective as of March 2, 2023, the Company and Indivior entered into the Indivior Amendment to the Indivior License Agreement. The Indivior Amendment was entered into for the primary purpose of amending the Agreement as follows: (i) extending the term of the Agreement until August 16, 2026 and thereafter providing for automatic renewal terms of successive one-year periods unless Indivior delivers notice to the Company, at least twelve months prior to the expiration of the then current term, of Indivior’s intent not to renew, subject to the earlier termination rights of the parties under the Agreement, and providing that the Agreement will not automatically renew for any renewal term beginning after the expiration of the last to expire of the product patents covered under the Indivior License Agreement; and (ii) agreeing to transfer pricing and payment terms for supplied product under the Indivior License Agreement. License Agreement with Sunovion Pharmaceuticals, Inc. On April 1, 2016, the Company entered into a license agreement with Cynapsus Therapeutics Inc. (which was later succeeded to in interest by Sunovion), referred to as the Sunovion License Agreement, pursuant to which Sunovion obtained an exclusive, worldwide license (with the right to sub-license) to certain intellectual property, including existing and future patents and patent applications, covering all oral films containing apomorphine for the treatment of off episodes in Parkinson’s disease patients. Sunovion used this intellectual property to develop its apomorphine product KYNMOBI®, which was approved by the FDA on May 21, 2020. This approval triggered Sunovion’s obligation to remit a payment of $4,000, due on the earlier of: (a) the first day of product availability at a pharmacy in the United States; or (b) within six months of FDA approval of the product. This amount was received as of September 30, 2020 and was included in License and royalty revenues for the twelve months ended December 31, 2020. Effective March 16, 2020, the Company entered into the First Amendment. The First Amendment was entered into for the primary purpose of amending the Sunovion License Agreement as follows: (i) including the United Kingdom and any other country currently in the EU which later withdraws as a member country in the EU for purpose of determining the satisfaction of the condition triggering the obligation to pay the third milestone due under the Sunovion License Agreement, (ii) extending the date after which Sunovion has the right to terminate the Sunovion License Agreement for convenience from December 31, 2024 to March 31, 2028, (iii) modifying the effective inception date of the first minimum annual royalty due from Sunovion to the Company from January 1, 2020 to April 1, 2020, and (iv) modifying the termination provision to reflect the Company’s waiver of the right to terminate the Sunovion License Agreement in the event that KYNMOBI was not commercialized by January 1, 2020. This Sunovion License Agreement will continue until terminated by Sunovion in accordance with the termination provisions of the First Amendment. The Sunovion License Agreement continues (on a country-by-country basis) until the expiration of all applicable licensed patents unless earlier terminated under the termination provisions contained therein. Upon termination of the Sunovion License Agreement, all rights to intellectual property granted to Sunovion to develop and commercialize apomorphine-based products will revert to the Company. On October 23, 2020, the Company amended the Sunovion License Agreement to clarify the parties' agreement with respect to certain provisions in the Sunovion License Agreement, specifically the date after which Sunovion has the right to terminate the Sunovion License Agreement and the rights and obligations of the parties regarding the prosecution and maintenance of the Company’s patents covered under the Sunovion License Agreement. In consideration of the rights granted to Sunovion under the Sunovion License Agreement, the Company received aggregate payments totaling $22,000 to date. In addition to the upfront payment of $5,000, the Company has also earned an aggregate of $17,000 in connection with specified regulatory and development milestones in the United States and Europe (the “Initial Milestone Payments”), all of which have been received to date. With the Monetization Agreement (defined below) entered into on November 3, 2020 relating to KYNMOBI as described in the paragraph below, the Company is no longer entitled to receive any payments under the Sunovion License Agreement. Purchase and Sale Agreement with an affiliate of Marathon On November 3, 2020, the Company entered into the Monetization Agreement with Marathon. Under the terms of the Monetization Agreement, the Company sold to Marathon all of its contractual rights to receive royalties and milestone payments due under the Sunovion License Agreement related to Sunovion’s apomorphine product, KYNMOBI. In exchange for the sale of these rights, the Company received an upfront payment from Marathon of $40,000 and an additional payment of $10,000 through the achievement of the first milestone. The Company has received an aggregate amount of $50,000 through March 31, 2026 under the Monetization Agreement. Under the Monetization Agreement, additional contingent payments of up to $75,000 may be due to the Company upon the achievement of worldwide royalty and other commercial targets within a specified timeframe, which could result in total potential proceeds of $125,000. In June 2023, Sunovion announced that it had voluntarily withdrawn KYNMOBI from the U.S. and Canadian markets; therefore, the Company likely will not receive any of the additional contingent payments under the Monetization Agreement. See Note 15, Sale of Future Revenue for further details on the accounting for the Monetization Agreement. Agreement to Terminate CLA with Zevra Therapeutics, Inc. (formerly KemPharm) In March 2012, the Company entered into an agreement with Zevra to terminate a Collaboration and License Agreement entered into by the Company and Zevra in April 2011.

Under that Asset Purchase Agreement, Assertio assigned and transferred its rights and certain obligations arising post closing to Cosette.
