Commitments and Contingencies Disclosure [Abstract] |
Commitments and Contingent Liabilities | 16. COMMITMENTS AND CONTINGENT LIABILITIES Litigation From time to time, the Company may be subject to legal proceedings and claims in the ordinary course of business. 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 would accrue a liability for the estimated loss. Because of uncertainties related to claims and litigation, accruals are based on the Company’s best estimates, utilizing all available information. On a periodic basis, as additional information becomes available, or based on specific events such as the outcome of litigation or settlement of claims, the Company may reassess the potential liability related to these matters and may revise these estimates, which could result in material adverse adjustments to the Company’s operating results. At September 30, 2025, there were no potential material losses from claims, asserted or unasserted, or legal proceedings that the Company determined were probable of occurring. For claims that are reasonably possible, no estimable loss or range of loss can be made. INVEGA TRINZA ANDA Litigation In September 2020, Janssen Pharmaceutica, Janssen Pharmaceuticals, Inc., and Janssen Research & Development, LLC initiated a patent infringement lawsuit in the U.S. District Court for the District of New Jersey (the “NJ District Court”) against Mylan Laboratories Limited (“Mylan Labs”) and other Mylan entities following the filing by Mylan Labs of an abbreviated new drug application (“ANDA”) seeking approval from the U.S. Food and Drug Administration (“FDA”) to market a generic version of INVEGA TRINZA before the expiration of U.S. Patent No. 10,143,693 (the “’693 Patent”). Requested judicial remedies include recovery of litigation costs and injunctive relief. In May 2023, the NJ District Court issued an opinion in favor of the Janssen entities on the issues of infringement and validity of the ’693 Patent and the Mylan entities filed a notice of appeal of the decision. In March 2025, the U.S. Court of Appeals for the Federal Circuit (the “Federal Circuit Court”) issued a decision affirming the NJ District Court opinion and in May 2025, Mylan Labs filed a petition for panel rehearing or rehearing en banc, which was denied on July 1, 2025. The Company is not a party to this proceeding. VUMERITY ANDA Litigation In July 2023, Biogen Inc., Biogen Swiss Manufacturing GmbH and Alkermes Pharma Ireland Limited (“APIL”), a wholly-owned subsidiary of the Company, filed a patent infringement lawsuit in the U.S. District Court for the District of Delaware (the “DE District Court”) against Zydus Worldwide DMCC, Zydus Pharmaceuticals (USA) Inc. and Zydus Lifesciences Limited (collectively, “Zydus”) following the filing by Zydus of an ANDA seeking approval from the FDA to engage in the commercial manufacture, use or sale of a generic version of VUMERITY (diroximel fumarate) delayed-release capsules for oral use, 231 mg, before expiration of the Company’s U.S. Patent Nos. 8,669,281; 9,090,558; and 10,080,733 (the “VUMERITY patents”). The filing of the lawsuit triggered a stay of FDA approval of the ANDA for up to 30 months in accordance with the U.S. Drug Price Competition and Patent Term Restoration Act of 1984 (the “Hatch-Waxman Act”). On July 21, 2025, the parties entered into a confidential settlement agreement, pursuant to which Zydus was granted a license under the VUMERITY patents to engage in the commercial manufacture, use or sale of a generic version of VUMERITY in the United States beginning on an agreed date immediately prior to expiration of the latest to expire of the VUMERITY patents, or earlier under certain customary circumstances. In connection with the settlement agreement, the DE District Court dismissed the litigation pursuant to the parties’ stipulation of dismissal. LYBALVI ANDA Litigation On August 15, 2025, August 27, 2025 and September 5, 2025, APIL and Alkermes, Inc., two wholly-owned subsidiaries of the Company, filed a patent infringement lawsuit in the NJ District Court against each of Teva, Apotex, and MSN (each as defined herein), respectively, and on August 28, 2025, APIL and Alkermes, Inc. filed a patent infringement lawsuit in the DE District Court against Apotex. As used herein, Teva refers to Teva Pharmaceuticals, Inc., Apotex refers to Apotex Inc. and Apotex Corp., and MSN refers to MSN Laboratories Private Limited (“MSN Labs”), MSN Pharmaceuticals, Inc. and Novadoz Pharmaceuticals LLC. These lawsuits were filed following receipt of a “paragraph IV certification” notice from each of Teva, Apotex and MSN Labs regarding their respective filings of an ANDA with the FDA seeking approval to engage in the commercial manufacture, use or sale of a generic version of LYBALVI (olanzapine and samidorphan tablets, 5mg/10mg, 10mg/10mg, 15mg/10mg and 20mg/10mg) in the U.S. prior to the expiration of certain of the Company’s U.S. patents. The notices alleged that certain of the Company’s patents related to LYBALVI, with expiration dates between 2032 and 2041, are invalid, unenforceable and/or will not be infringed by the commercial manufacture, use or sale of the proposed generic products. The Company intends to vigorously defend its intellectual property. The filing of each lawsuit within 45 days of receipt of each of the respective notices triggered stays of FDA approval of each of the respective ANDAs for up to 30 months in accordance with the Hatch-Waxman Act. On August 20, 2025, APIL and Alkermes, Inc. amended the complaint in the lawsuit against Teva to include an additional patent. Antitrust Class Action Litigation On October 2, 2025, Value Drug Company filed a complaint asserting antitrust claims against Alkermes, Inc. and APIL in the U.S. District Court for the District of Massachusetts. The complaint was filed on behalf of a putative class of direct purchasers of VIVITROL and alleges that the Company’s U.S. Patent No. 7,919,499 related to VIVITROL was fraudulently obtained, improperly listed in the Orange Book, and wrongfully enforced, resulting in delayed market entry for generic forms of VIVITROL. The lawsuit seeks, among other things, unspecified money damages plus interest, reasonable attorneys’ fees and other costs. The Company intends to vigorously defend itself in this matter. Government Matters The Company has received a subpoena and civil investigative demands from U.S. state and federal governmental authorities. The Company is cooperating with the investigations. Product Liability and Other Legal Proceedings The Company is involved in litigation and other legal proceedings incidental to its normal business activities, including a product liability case alleging that the FDA-approved VIVITROL labeling was inadequate and that VIVITROL caused the individual to suffer from opioid overdose and death. The Company intends to vigorously defend itself in these matters. In addition, in January 2023, Acorda Therapeutics, Inc. (“Acorda”) filed a petition with the U.S. District Court for the Southern District of New York (the “NY Southern District Court”) asking the court to confirm in part and modify in part the final arbitral award rendered by an arbitration panel in October 2022 and, as part of the requested modification, seeking an additional approximately $66.0 million in damages. In August 2023, the NY Southern District Court confirmed the final arbitral award and declined to modify the final award to increase the damages awarded thereunder. In September 2023, Acorda filed a notice of appeal of the NY Southern District Court decision to the Federal Circuit Court. On July 25, 2025, the Federal Circuit Court transferred the appeal due to lack of jurisdiction to the U.S. Court of Appeals for the Second Circuit. Guarantees In connection with the Separation, the Company entered into an assignment and assumption of lease agreement (the “Assignment”) pursuant to which Alkermes, Inc., a wholly owned subsidiary of the Company, assigned to Mural Oncology, Inc. (“Mural US”), a subsidiary of Mural, an operating lease for approximately 180,000 square feet of corporate office space, administrative areas and laboratories located at 852 Winter Street in Waltham, Massachusetts (the “852 Winter Street Lease”), as described in more detail in Note 10, Leases in the “Notes to Consolidated Financial Statements” in the Annual Report. Although all of the rights, title and interest in, to and under the 852 Winter Street Lease were transferred to Mural US as of November 15, 2023 pursuant to the Assignment, the Company ratified and reaffirmed for the remainder of the lease term its guarantor obligations in respect of the lease under that certain Guaranty dated as of May 16, 2014. This lease expires in 2026 and we do not expect its term to be extended. Upon completion of the Separation, the Assignment was accounted for as a termination of the original lease and the Company de-recognized the right-of-use asset and lease liability related to the 852 Winter Street Lease. At September 30, 2025, the fair value of the guarantee was no t material to the Company.
