The Offering is expected to close on February 27, 2026, subject to the satisfaction of customary closing conditions.

Pursuant to the terms of the Underwriting Agreement, Vir Bio granted the Underwriters an option, exercisable for 30 days, to purchase up to an additional 2,647,058 shares of Common Stock at the public offering price.

Vir Bio expects to receive net proceeds from the Offering of approximately $141.1 million, or approximately $162.3 million if the Underwriters exercise in full their option to purchase additional shares, after deducting underwriting discounts and commissions and estimated Offering expenses.

The Underwriting Agreement contains customary representations, warranties and covenants by Vir Bio, customary conditions to closing and indemnification obligations of Vir Bio and the Underwriters against certain liabilities.
