Legal Proceedings

• Regenx and U-Penn lawsuit (U.S. District Court for the District of Delaware) for patent infringement of U.S. Patent No. 10,526,617 ('617 Patent) related to AAV gene therapy products, including ELEVIDYS. Sarepta's motion for summary judgment on invalidity was granted, but plaintiffs appealed to the U.S. Court of Appeals for the Federal Circuit.
• Second Regenx and U-Penn patent infringement lawsuit (U.S. District Court for the District of Delaware) against Sarepta and Catalent, asserting infringement of U.S. Patent No. 11,680,274 ('274 Patent) related to ELEVIDYS. The case is stayed pending Inter Partes Review (IPR) proceedings, where PTAB found the sole remaining claim not unpatentable, and Sarepta filed a notice of appeal.
• Nippon Shinyaku Co., Ltd. (NS) lawsuit (U.S. District Court for the District of Delaware) for breach of contract and patent infringement of NS Patents concerning exon 53 skipping technology (VYONDYS 53). Sarepta counterclaimed for infringement of UWA Patents by NS's Viltepso. A jury found NS's 092 Patent invalid and Sarepta's/UWA's 851 Patent not invalid, awarding Sarepta approximately $115.2 million in damages for U.S. sales and $0.8 million for ex-U.S. sales through December 15, 2024. Post-trial motions are pending.
• Genzyme Corporation lawsuit (U.S. District Court for the District of Delaware) asserting infringement of U.S. Patent Nos. 9,051,542 ('542 Patent) and 7,704,721 ('721 Patent) arising from ELEVIDYS. Genzyme later amended the complaint to include new allegations related to five additional patents. Sarepta has submitted IPR petitions challenging the validity of the '542 and '721 Patents.
• Brammer Bio MA, LLC arbitration demand relating to the termination of the Thermo Agreement. Settled on July 12, 2025, with Sarepta agreeing to pay Brammer $13.0 million.
• Putative securities class action complaint (U.S. District Court for the Southern District of New York) filed against the Company and certain officers, alleging violations of the Securities Exchange Act of 1934 and Rule 10b-5 related to ELEVIDYS safety and efficacy disclosures and financial statements. Lead plaintiffs and counsel have been appointed, and a motion to transfer venue is pending.
• Shareholder derivative lawsuits (U.S. District Court for the Southern District of New York) filed against company directors and certain officers, alleging breaches of fiduciary duties and Section 14(a) of the Exchange Act related to similar disclosures as the securities action. These actions have been consolidated.

Related Party Transactions

• The Michael A. Chambers Living Trust, an affiliate of Michael Chambers (a director), entered into a Rule 10b5-1 trading plan on September 16, 2025, for the sale of 88,286 shares of common stock, with an end date of October 31, 2026.

Stakeholder Impact

• **Shareholders:** Significant net losses, stock price volatility, and dilution risk from potential future capital raises. Multiple lawsuits (securities class action, derivative actions) could lead to substantial costs and further impact share price.
• **Employees:** A 36% workforce reduction (approximately 500 employees) as part of the restructuring plan, leading to job losses and potential impact on employee morale and retention.
• **Patients:** Suspension of ELEVIDYS shipments to non-ambulatory patients and a clinical hold on LGMD gene therapy trials (SRP-9003, SRP-9004) due to safety concerns (acute liver failure and patient death) directly impacts patient access to treatments and clinical trial participation. The failure of the ESSENCE trial for VYONDYS and AMONDYS creates uncertainty for patients relying on these PMO products.
• **Partners (e.g., Roche, Arrowhead, Catalent):** Ongoing collaboration agreements are impacted by regulatory decisions (e.g., ELEVIDYS approval in Japan, supply delays with Catalent) and milestone achievements (Arrowhead DM1 milestone). Litigation with partners (e.g., Catalent arbitration, Genzyme lawsuit) can strain relationships and incur costs.
• **Creditors:** The partial refinancing of convertible notes extends maturity, but the company's ability to service debt depends on future performance and cash flow, which is under pressure from operational challenges and losses.

Next Steps

• Ongoing discussions with the FDA regarding a labeling supplement for ELEVIDYS, including a boxed warning for acute liver injury and acute liver failure and removal of the non-ambulatory population from the Indication and Usage section.
• Discussions with the FDA regarding the potential pathway forward for VYONDYS 53 and AMONDYS 45 following the ESSENCE trial results, including a path to traditional approval.
• Evaluation of the financial impact of the ESSENCE trial results on financial statements, including recoverability of AMONDYS 45 and VYONDYS 53 inventories.
• Meeting with the FDA in 2025 regarding a Biologics License Application (BLA) submission for SRP-9003.
• Sharing initial data for siRNA product candidates SRP-1003 (DM1) and SRP-1001 (FSHD) in the first quarter of 2026.
• Continued building out of the network for commercial distribution in jurisdictions where products are approved or seeking approval.
• Continued assessment of the realizability of deferred tax assets on a quarterly basis.

Key Dates

Recommendation

The filing presents a highly concerning outlook for Sarepta Therapeutics. The significant net losses for both the three and nine months ended September 30, 2025, coupled with a 15% decline in total revenues for the quarter, indicate deteriorating financial performance. The core product, ELEVIDYS, faces substantial headwinds with the suspension of shipments to non-ambulatory patients, a clinical hold on LGMD gene therapy trials due to patient death, and the revocation of its platform technology designation by the FDA. Furthermore, the ESSENCE confirmatory trial for two other key PMO products (VYONDYS and AMONDYS) failed to meet its primary endpoint, raising serious questions about their continued market viability and potential for regulatory action, including withdrawal. The strategic restructuring, while aimed at cost reduction, involves a substantial 36% workforce reduction and a significant charge, signaling deep operational challenges. Multiple ongoing legal proceedings, including securities class action and patent infringement lawsuits, add further uncertainty and potential financial burden. While the debt refinancing provides some liquidity relief, the overall picture of declining sales, regulatory setbacks, and significant losses suggests a 'sell' recommendation for a seasoned investor or institution, as the risks appear to outweigh potential upsides in the near to medium term.
