Arbutus Biopharma (NASDAQ: ABUS) has formally ended a 2025 patent collaboration with Genevant Sciences that was linked to Moderna’s respiratory syncytial virus (RSV) vaccine program. This step follows a settlement with Moderna that delivered approximately $178 million to Arbutus, bringing closure to a series of worldwide patent disputes surrounding lipid nanoparticle (LNP) technology used in COVID‑19 vaccines. The settlement with Moderna, received on July 8, 2026, represents Arbutus’ share of a non‑contingent payment that resolves all outstanding patent claims between the parties.

§1498. Arbutus and Genevant have also pursued compensation from the U.S. government in the Court of Federal Claims for vaccine doses supplied to federal agencies, a action that may affect the ultimate size of the payout.

With the newly available capital, Arbutus intends to initiate a share repurchase program that could total up to approximately $230 million. The company plans to execute these buybacks during the third quarter of 2026, reflecting confidence in its balance sheet and a desire to return value to shareholders while it continues to enforce its patent rights against other industry players. In recognition of the successful settlement, the company’s senior management received one‑time cash bonuses drawn from the proceeds.

The bonuses were structured as lump‑sum awards and are intended to acknowledge the contribution of leadership to the resolution of the litigation. Looking ahead, Arbutus will monitor developments related to its ongoing litigation, including any further determinations under §1498, and will assess the timing of the share repurchase program. The company’s ownership stake of approximately 16% in its parent entity further aligns its interests with those of shareholders as it moves forward.
