Roivant Announces Genevant Sciences’ and Arbutus Biopharma’s $2.25 Billion Global Settlement With Moderna

• Moderna to pay Genevant and Arbutus $950 million upfront and an additional $1.3 billion contingent upon a favorable resolution of Moderna’s Section 1498 appeal
• If the $1.3 billion payment is realized, this settlement will be the largest disclosed patent settlement paid in the pharmaceutical industry and the second largest in any industry
• Settlement holds Moderna accountable for infringement and provides for the court to enter judgment of no invalidity on the four Genevant/Arbutus patents asserted in the case
• Genevant grants Moderna a global non-exclusive license to its LNP delivery technology for SM-102-containing mRNA vaccines for infectious disease and a covenant not to sue for certain Genevant/Arbutus patents and Moderna products, ending all patent-infringement litigation against Moderna arising from its unauthorized use of the technology in its COVID-19 vaccines
• Pfizer/BioNTech litigation is ongoing in the United States following a favorable Markman ruling issued in September 2025; Comirnaty sales represent ~2/3 of global COVID-mRNA vaccine sales to date
• Roivant’s board of directors has approved a $1 billion share repurchase program, inclusive of the $500 million authorization that was approved in June 2025
• Roivant will host an investor call to discuss these updates today, March 3, 2026, at 4:45 p.m. ET

BASEL, Switzerland and LONDON and NEW YORK, March 03, 2026 (GLOBE NEWSWIRE) -- Roivant (Nasdaq: ROIV) today announced that Genevant Sciences, a leading nucleic acid delivery company with world-class platforms and a robust lipid nanoparticle (LNP) patent portfolio and a subsidiary of Roivant, and Arbutus Biopharma Corporation (Nasdaq: ABUS), a clinical-stage biopharmaceutical company focused on infectious disease, have entered into a $2.25 billion global settlement with Moderna, Inc. to resolve all U.S. and international enforcement actions involving Moderna’s unauthorized use of Genevant’s and Arbutus’ LNP delivery technology in its COVID-19 vaccines, including Spikevax^®.

As part of the settlement, Moderna will pay Genevant and Arbutus $950 million upfront in July 2026 and an additional $1.3 billion contingent upon an appellate ruling that 28 U.S.C. § 1498 (Section 1498) does not bar Genevant’s and Arbutus’ claims against Moderna for patent infringement, except as to doses characterized by the district court as having gone to U.S. government employees. In asserting that defense, Moderna argued that Section 1498 applies such that U.S. taxpayers should assume liability for its infringement of Genevant’s and Arbutus’ patents for sales made under one of its government contracts. Moderna has also consented to entry of a judgment of infringement and of no invalidity of four Genevant/Arbutus patents. Additionally, as a part of this settlement, Genevant has agreed to grant Moderna a global non-exclusive license to LNP delivery technology for infectious disease applications and a covenant not to sue for certain Genevant/Arbutus patents and Moderna products. For more information about the terms and conditions of the settlement with Moderna, including the contingent payment, please refer to Roivant’s Current Report on Form 8-K filed with the SEC on March 3, 2026.

“We are pleased with this settlement, which allows us to put this lengthy dispute behind us and remain focused on our mission to leverage our world-class nucleic acid delivery systems to bring innovative medicines to people who need them,” said James Heyes, CEO of Genevant Sciences. “At the same time, it is enormously gratifying for the Genevant team to, at long last, be recognized for our pivotal contribution to restoring normalcy around the world in the face of a once-in-a-lifetime pandemic.”

“Nobel laureates, industry executives, and prominent researchers have long recognized that Arbutus scientists changed the drug development landscape when they invented LNP delivery technology, enabling nucleic acids including mRNA to be used for medicines and opening a new world of possibilities,” said Lindsay Androski, President and Chief Executive Officer of Arbutus. “Today, Moderna has finally acknowledged the same. This is a transformative outcome for Arbutus as a company, but more importantly, it is a long-overdue recognition that the COVID-19 vaccines would never have made it to the world without the seminal work of Ian MacLachlan, Ed Yaworski, Lloyd Jeffs, Kieu Lam, Lorne Palmer, and Cory Giesbrecht. Today, above all else, we celebrate – and in the case of Cory, remember – them.”

"This outcome speaks to the fundamental role that Genevant’s foundational LNP technology played in enabling the world's response to the COVID-19 pandemic. As we continue to pursue our ongoing litigation against Pfizer/BioNTech, whose Comirnaty sales represent ~2/3 of global COVID vaccine sales, this resolution with Moderna reduces uncertainty, validates our IP estate and provides near term significant cash inflow,” said Matt Gline, CEO of Roivant. “We will continue to be capital efficient with these proceeds with an additional $500 million authorized by our board for share repurchases.”
