AI brief of an SEC Form 8-K · Vir Biotechnology (VIR)

Vir Biotechnology CFO Jason O'Byrne to step down effective August 3, 2026

Neutral Impact 4 of 5 leadership Written later

Vir Biotechnology's Chief Financial Officer, Jason O'Byrne, will step down effective August 3, 2026 to pursue another opportunity, and the company says his departure was not due to any disagreement on its operations, policies, or practices. The board has named Brent Sabatini, the company's Chief Accounting Officer, as interim principal financial officer effective the same date while Vir searches for a successor, a change that matters to shareholders because it concerns who leads financial reporting during the transition.

Key points

  • Jason O'Byrne, Executive Vice President and Chief Financial Officer, informed Vir on July 20, 2026 that he will step down effective August 3, 2026.
  • The board appointed Brent Sabatini, Senior Vice President and Chief Accounting Officer, as interim principal financial officer on July 23, 2026, effective August 3, 2026.
  • Sabatini has served as Chief Accounting Officer since February 2023 and as principal accounting officer since October 2024; he will receive no added compensation for the interim role.
  • Vir has initiated a search for O'Byrne's successor; the filing gives no timeline for that search.
