Moderna, Inc.

Item 1. Legal Proceedings

We are involved in various claims and legal proceedings of a nature considered ordinary course in our business, including those described in our 2025 Form 10-K under the heading “Legal Proceedings.” Most of the issues raised by these claims are highly complex and subject to substantial uncertainties. For a description of risks relating to these and other legal proceedings we face, see Part I, Item 1A., “Risk Factors,” of our 2025 Form 10-K, including the discussion under the headings entitled “Risks related to our intellectual property” and “Risks related to the manufacturing of our commercial products and product candidates.” The outcome of any such proceedings, regardless of the merits, is inherently uncertain; therefore, assessing the likelihood of loss and any estimated damages is difficult and subject to considerable judgment.

Arbutus Patent Litigation

As more fully described in our 2025 Form 10-K, Arbutus Biopharma Corporation (Arbutus) and Genevant Sciences GmbH (Genevant) brought patent infringement actions against us in various jurisdictions, including in the U.S. District Court for the District of Delaware. On March 3, 2026, we entered into a settlement agreement with Arbutus and Genevant to resolve all patent infringement litigation pending worldwide. For more information, please see “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Settlement with Arbutus and Genevant.”

CureVac Patent Litigation

In April 2026, CureVac SE and CureVac Manufacturing GmbH filed a complaint against us in the U.S. District Court for the District of Delaware asserting that our manufacture and sale of Spikevax willfully infringes U.S. patents directed to RNA production methods and compositions with RNA encoding modified SARS-CoV-2 spike protein. The complaint seeks a judgment of infringement of the asserted patent and unspecified damages.
