Reverse Stock Split

On March 9, 2026, Reviva completed a 1-for-20 reverse stock split of its issued and outstanding shares of common stock. The Reverse Split did not change the number of authorized shares of common stock or par value of common stock. No cash or fractional shares were issued in connection with the Reverse Split, and instead the Company rounded up to the next whole share in lieu of issuing factional shares that would have been issued in the Reverse Split. Proportional adjustments were made to the number of shares of common stock issuable upon exercise or conversion of the Company’s outstanding stock options, restricted common stock, and warrants, the exercise price of the Company’s outstanding stock options, restricted common stock and warrants, and the number of shares reserved for issuance under the Company’s equity incentive plan. All share, common stock warrant, prefunded warrant, restricted common stock and common stock option amounts, and per share, per common stock warrant, per prefunded warrant, per restricted common stock and per common stock option amounts, in these consolidated financial statements have been retrospectively adjusted as appropriate to reflect the Reverse Stock Split.
