As previously reported by Vaxart, Inc. (the "Company"), on August 27, 2025, the Nasdaq Hearings Panel (the "Panel") of The Nasdaq Stock Market LLC ("Nasdaq") granted the Company's request to continue its listing on Nasdaq subject to the Company's (i) receipt of shareholder approval for a reverse stock split on or before September 5, 2025, (ii) completion of such reverse stock split on or before October 6, 2025, and (iii) demonstration of compliance with Nasdaq's minimum bid price requirement (the "Panel's Conditions").
