Under these license agreements, the Company may be required to pay certain amounts upon the achievement of defined milestones. If these products are ultimately commercialized, the Company is also obligated to pay royalties to third parties, computed as a percentage of net product sales, for each respective product under a license agreement.
Through the USWM Acquisition, the Company acquired licensing agreements with other pharmaceutical companies for APOKYN, ONAPGO, XADAGO, and MYOBLOC.

USWM Enterprises Commitments Assumed
As part of the USWM Acquisition, the Company assumed the remaining commitments of USWM Enterprises and its subsidiaries, which are discussed below.
The Company assumed the annual minimum purchase requirement of MYOBLOC, amounting to an estimated €3.9 million annually, under the contract manufacturing agreement with Merz for manufacture and supply. An amendment to the contract manufacturing agreement with Merz was executed in July 2025. Amendments to the contract manufacturing agreement included among other things, the removal of the annual minimum purchase requirement of MYOBLOC, and the Company's agreement to pay a nonrefundable annual fee of €3.0 million to cover general maintenance and reservation costs for the manufacturing facilities.
MDD US Operations, LLC (formerly US WorldMeds, LLC) and its subsidiary, Solstice Neurosciences, LLC (US) (collectively, the MDD Subsidiaries) entered into a Corporate Integrity Agreement (CIA) with the Office of Inspector General of the U.S. Department of Health and Human Services which was effective in April 2019. Under the CIA, the MDD Subsidiaries agreed to and paid $17.5 million to resolve U.S. Department of Justice allegations that it violated the False Claims Act and committed to the establishment and ongoing maintenance of an effective compliance program. The fine was paid by the MDD Subsidiaries prior to closing of the USWM Acquisition. As part of the USWM Acquisition, the Company assumed the obligations of the CIA and could become liable for payment of certain stipulated monetary penalties in the event of any CIA violations. In addition, the Company continues to maintain a broad array of processes, policies and procedures necessary to comply with the CIA and submitted its final report during the second quarter of 2024. The Company received an official notification of release from the Office of the Inspector General in April 2025 and thus no longer remains subject to its obligations under the CIA.
Claims and Litigation
From time to time, the Company may be involved in various claims, litigation and legal proceedings. These matters may involve patent litigation, product liability and other product-related litigation, commercial and other matters, and government investigations, among others. On a quarterly basis, the Company reviews the status of each significant matter and assesses its potential financial exposure. If the potential loss from any claim, asserted or unasserted, or legal proceeding is considered probable and the amount can be reasonably estimated, the Company will accrue a liability for the estimated loss. Because of uncertainties related to claims, legal proceedings and litigation, accruals will be based on the Company's best estimates based on available information. The Company does not believe that any of these matters will have a material adverse effect on its financial position. The Company may reassess the potential liability related to these matters and may revise these estimates. The process of resolving matters through litigation or other means is inherently uncertain and it is possible that an unfavorable resolution of these matters will adversely affect the Company, its results of operations, financial condition and cash flows.
NAMENDA XR/Namzaric Qui Tam Litigation
On April 1, 2019, Adamas was served with a complaint filed in the United States District Court for the Northern District of California (the District Court) (Case No. 3:18-cv-03018-JCS) against it and several Allergan entities alleging violations of federal and state false claims acts (FCA) in connection with the commercialization of NAMENDA XR and Namzaric by Allergan. The lawsuit is a qui tam complaint brought by an individual, asserting rights of the federal government and various state governments. The lawsuit was originally filed in May 2018 under seal, and Adamas became aware of the lawsuit when it was served. The complaint alleges that patents held by Allergan and Adamas covering NAMENDA XR and Namzaric were procured through fraud on the United States Patent and Trademark Office and that these patents were asserted against potential generic
manufacturers of NAMENDA XR and Namzaric to prevent the generic manufacturers from entering the market, thereby wrongfully excluding generic competition resulting in artificially high price being charged to government payors. Adamas' patents in question were licensed exclusively to Forest Laboratories Holdings Limited. The complaint includes a claim for damages of "potentially more than $2.5 billion dollars," treble damages and statutory penalties. To date the federal and state governments have declined to intervene in this action. This case is currently stayed pending Adamas's and Allergan's interlocutory appeal of the District Court's December 11, 2020 order denying Adamas's and Allergan's motion to dismiss the complaint. The appeal is pending in the United States Court of Appeals for the Ninth Circuit (Case No. 21-80005). Argument was held on January 10, 2022. On August 25, 2022, the Ninth Circuit sided with the defendants by reversing the District Court’s public disclosure bar rulings and remanding the case back to the District Court to decide certain issues in the first instance. On October 11, 2022, the plaintiff filed a petition for rehearing with the Ninth Circuit which was denied on November 3, 2022. On December 23, 2022, the defendants filed renewed motions to dismiss directed to the remaining unresolved issue. On March 20, 2023, the District Court entered an order and final judgment dismissing with prejudice the FCA claim while declining to exercise supplemental jurisdiction over the state false claims act claims which were dismissed without prejudice. On April 19, 2023, the plaintiff appealed the District Court's dismissal of the Federal False Claims Act claim. On February 20, 2024, the plaintiff filed a motion for an indicative ruling and to set aside the judgment in the District Court, based on the same arguments raised in his appeal. That motion was fully briefed and the District Court determined that the motion for an indicative ruling was suitable for determination without a hearing. On May 7, 2024, the District Court denied the plaintiff’s motion for an indicative ruling. The appeal is fully briefed, and the Ninth Circuit heard oral argument on November 21, 2024. On January 29, 2025, the Ninth Circuit affirmed the District Court’s order dismissing the litigation. On March 31, 2025, the plaintiff filed a petition for rehearing by the Ninth Circuit, but the Ninth Circuit denied the Petition on April 15, 2025. The plaintiff opted not to seek review from the U.S. Supreme Court. It remains to be seen whether he will attempt to refile any of his state-law FCA claims. The Company intends to defend itself vigorously. However, the Company can offer no assurances that it will be successful in a litigation.
APOKYN Litigation
On October 3, 2022, Sage Chemical, Inc. and TruPharma, LLC filed a lawsuit in the United States District Court for the District of Delaware alleging that Supernus Pharmaceuticals, Inc., Britannia Pharmaceuticals Limited (Britannia), and US WorldMeds Partners, LLC (US WorldMeds) violated state and federal antitrust law in connection with APOKYN® (apomorphine HCl). On October 16, 2022, Plaintiffs amended their complaint to add additional defendants MDD US Enterprises, LLC, MDD US Operations, LLC (each a subsidiary of Supernus Pharmaceuticals, Inc.), USWM, LLC (USWM), and individual defendants Paul Breckinridge Jones, Sr., Herbert Lee Warren, Jr., Henry Van Den Berg, and Kristin L. Gullo. On January 10, 2023, Defendants filed an Omnibus Motion to Dismiss the Amended Complaint seeking dismissal of each of Plaintiffs’ claims and the lawsuit in its entirety and US WorldMeds with USWM, Britannia, and the group of individual defendants each filed separate motions to dismiss. On May 9, 2024, and May 28, 2024, respectively, the Court denied the Defendants’ omnibus motion and the Britannia motion to dismiss. On May 31, 2024, and June 4, 2024, respectively, the Court granted the individual defendants’ motion to dismiss and the US WorldMeds and USWM motion to dismiss. On December 6, 2024, Plaintiffs filed a second amended complaint, which added US WorldMeds and USWM back to the case. The Court ordered on February 3, 2026, that case dispositive and Daubert motions briefing would begin on June 9, 2026, with a hearing scheduled for September 18, 2026, pretrial conference set for January 15, 2027, and trial beginning January 25, 2027.
The Company intends to defend itself vigorously. However, the Company can offer no assurances that it will be successful in a litigation.
Sage Legal Proceedings
Merger Complaints
In connection with the Merger Agreement and Sage's Board of Directors' (Sage Board) recommendation to Sage shareholders to tender their shares pursuant to the tender offer, two purported Sage shareholders filed complaints in state court against Sage and each member of the Sage Board. Among other things, the complaints assert claims for negligent misrepresentation and concealment and negligence under New York common law. Sage has also received certain demand letters from other purported shareholders with similar allegations to those contained in the complaints. Additional demand letters may be received by Sage and additional complaints may be filed against Sage, the Sage Board, Supernus and Saphire, Inc. in connection with the Merger Agreement and tender offer.
Securities Class Action
On August 28, 2024, named plaintiff Darren Korver filed a purported federal securities class action lawsuit in the Southern District of New York against Sage and individuals, Barry E. Greene and Kimi Iguchi (Securities Class Action). The complaint in the Securities Class Action alleges violations of U.S. securities laws under Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 and Rule 10b-5 promulgated thereunder and seeks an as-yet unspecified amount of damages allegedly sustained by parties who purchased Sage stock between April 12, 2021 and July 23, 2024, as well as applicable attorneys’ fees and costs. Sage denies any allegations of wrongdoing and intends to vigorously defend against the Securities Class Action.
U.S. Securities and Exchange Commission (SEC) Investigation
On October 16, 2024, Sage received a subpoena from the Enforcement Division of the SEC requesting documents and information related to Sage’s NDA for zuranolone for the treatment of major depressive disorder (MDD), including communications with the FDA and any communications containing material nonpublic information. The Company is cooperating with the SEC and intends to continue to provide information responsive to the SEC’s requests.
Consolidated Derivative Litigations
On March 26, 2025, plaintiff shareholder Qingping Zhu commenced derivative litigation in the Southern District of New York, purportedly on behalf of Sage, against sixteen current and former officers and directors of Sage (the Zhu Derivative Litigation). Based significantly on the allegations underlying the Securities Class Action, the Zhu Derivative Litigation alleges violations of Section 14(a) of the Exchange Act and Rule 14a-9 promulgated thereunder, breaches of fiduciary duty, unjust enrichment, and waste of corporate assets, and seeks unspecified damages and various equitable relief. On April 14, 2025, the Southern District of New York granted a stay of the Zhu Derivative Litigation pending the resolution of the motion to dismiss the amended complaint in the Securities Class Action.
On May 13, 2025, plaintiff shareholder Jurgen Matton commenced derivative litigation in the Southern District of New York, purportedly on behalf of Sage Therapeutics, against sixteen current and former officers and directors of Sage Therapeutics (the Matton Derivative Litigation). Based significantly on the allegations underlying the Securities Class Action, the Matton Derivative Litigation alleges violations of Section 14(a) of the Exchange Act and Rule 14a-9 promulgated thereunder, breaches of fiduciary duty, unjust enrichment, and waste of corporate assets, and seeks unspecified damages and various equitable relief.
On May 22, 2025, plaintiff shareholder Joseph Pizzelanti commenced derivative litigation in the Southern District of New York, purportedly on behalf of Sage Therapeutics, against sixteen current and former officers and directors of the Company (the Pizzelanti Derivative Litigation). Based significantly on the allegations underlying the Securities Class Action, the Pizzelanti Derivative Litigation alleges violations of Section 14(a) of the Exchange Act and Rule 14a-9 promulgated thereunder, breaches of fiduciary duty, unjust enrichment, and waste of corporate assets, and seeks unspecified damages and various equitable relief.
On June 20, 2025, Sage, along with other relevant parties, submitted for the Southern District of New York’s approval of a consolidation of the Zhu Derivative Litigation with the Matton Derivative Litigation and the Pizzelanti Derivative Litigation and the court approved such consolidation (the Consolidated Derivative Litigation).
At this time, the Company is unable to predict the outcome of the Merger Complaints, Securities Class Action, the SEC investigation, or the Consolidated Derivative Litigation, or reasonably estimate a range of possible losses. The outcome of the matters described above cannot be predicted with certainty. The Company intends to defend itself vigorously. However, the Company can offer no assurances that it will be successful in a litigation.

About Commitments Disclosures
Commitments and contingencies disclosures catalog a company's off-balance-sheet obligations and legal exposures — purchase commitments, guarantee arrangements, pending litigation, and regulatory proceedings. These items represent potential future cash outflows that may not appear as liabilities on the balance sheet until they become probable and estimable.
Key signals: litigation reserves and disclosed loss ranges quantify management's estimate of legal exposure, but unquantified "reasonably possible" losses often represent the larger risk. Watch for changes in language around pending cases — shifts from "remote" to "reasonably possible" or increases in estimated loss ranges signal deteriorating outcomes. Unconditional purchase obligations and take-or-pay contracts create fixed cost structures that reduce operational flexibility. Guarantee arrangements for subsidiaries or joint ventures can create cascading obligations. Compare the total commitment schedule against projected free cash flow to assess whether the company can meet its obligations without additional financing.
