The Company currently utilizes a single specialty pharmacy provider as its sole distributor for both MIPLYFFA and OLPRUVA.

All estimated reserve liabilities related to commercial products are recorded within the current portion of discount and rebate liabilities in the consolidated balance sheets. To commercialize MIPLYFFA and OLPRUVA in the United States, the Company has built marketing, sales, medical affairs, distribution, managerial and other non-technical capabilities or has made arrangements with third parties to perform these services. All revenues derived from sales of MIPLYFFA and OLPRUVA are in the United States.

For the years ended December 31, 2025, and 2024, the Company recognized revenue related to the global EAP of $13.0 million and $9.1 million, respectively, net of a clawback liability of $6.1 million and $5.7 million, respectively, and other gross to net adjustments.
The total estimated reserve liability as of December 31, 2025, and 2024, was $15.3 million and $12.6 million, respectively. As of December 31, 2025, and 2024, this estimated reserve liability is recorded as discount and rebate liabilities in the consolidated balance sheets and is separated into current and long-term based upon the timing of the expected payment to the French regulators.
AZSTARYS License Agreement
The Company entered into a Collaboration and License Agreement (the “AZSTARYS License Agreement”) with Commave Therapeutics SA (formerly known as Boston Pharmaceuticals Holdings SA) (“Commave”), an affiliate of Gurnet Point Capital, L.P., dated September 3, 2019. Under the AZSTARYS License Agreement, as amended, the Company granted to Commave an exclusive, worldwide license to develop, manufacture and commercialize the Company’s product candidates containing SDX and d-MPH, including AZSTARYS, or any other product candidates containing SDX and developed to treat ADHD or any other central nervous system disorder. Corium Inc. was tasked by Commave to lead all commercialization activities for AZSTARYS under the AZSTARYS License Agreement. Pursuant to the AZSTARYS License Agreement, Commave agreed to pay milestone payments up to an aggregate of $590.0 million upon the occurrence of specified regulatory milestones related to AZSTARYS, additional fixed payments upon the achievement of specified U.S. sales milestones, and quarterly, tiered royalty payments based on a range of percentages of net sales (as defined in the AZSTARYS License Agreement). Commave is obligated to make such royalty payments on a product-by-product basis until expiration of the royalty term for the applicable product.
The Company concluded that these regulatory milestones, sales milestones and royalty payments each contain a significant uncertainty associated with a future event. As such, these milestone and royalty payments are constrained at contract inception and are not included in the transaction price, as the Company could not conclude that it is probable a significant reversal in the amount of cumulative revenue recognized will not occur surrounding these milestone payments. At the end of each reporting period, the Company updates its assessment of whether the milestone and royalty payments are constrained by considering both the likelihood and magnitude of the potential revenue reversal. For the years ended December 31, 2025, and 2024, the Company recognized revenue under the AZSTARYS License Agreement of $5.0 million and $4.3 million, respectively. There was no deferred revenue related to this agreement as of December 31, 2025, and 2024. All revenues recognized under this agreement were derived in the United States.
The AZSTARYS License Agreement is within the scope of ASC 606, as the transaction represents a contract with a customer where the participants function in a customer/vendor relationship and are not exposed equally to the risks and rewards of the activities contemplated under the AZSTARYS License Agreement.
Relief Exclusive License Agreement
Pursuant to the Relief License Agreement, Relief will hold exclusive development and commercialization rights for OLPRUVA in the EU, Liechtenstein, San Marino, Vatican City, Norway, Iceland, Principality of Monaco, Andorra, Gibraltar, Switzerland, United Kingdom, Albania, Bosnia, Kosovo, Montenegro, Serbia and North Macedonia (“Geographical Europe”). The Company has the right to receive a royalty of up to 10% of the net sales of OLPRUVA in Geographical Europe. For the years ended December 31, 2025, and 2024, the Company did not recognize any revenue under the Relief License Agreement. There was no deferred revenue related to this agreement as of December 31, 2025, and 2024.

About Revenue Disclosures

Revenue disclosures under ASC 606 explain how a company identifies performance obligations, allocates transaction prices, and determines when revenue is recognized. This section is essential for understanding whether reported revenue reflects genuine economic activity or aggressive accounting choices. Analysts examine the mix of point-in-time versus over-time recognition, which directly affects revenue timing and comparability.

Key signals: rising contract liabilities (deferred revenue) suggest strong future revenue visibility, while declining contract assets may indicate slowing project milestones. Watch for variable consideration estimates — rebates, returns, and performance bonuses that require management judgment. Significant changes in disaggregated revenue by geography or product line can reveal shifting business mix before it appears in headline numbers. Compare revenue growth against contract liability growth to assess sustainability, and scrutinize any changes in the timing of recognition that coincide with earnings pressure.
