• Vaxart published an open letter urging shareholders to back its board ahead of the July 16, 2026 annual meeting, citing a proxy contest in which dissident investors nominated three directors.
• Management framed the next 12–18 months as a key inflection period for its oral vaccine platform, highlighting a fully enrolled BARDA-backed Phase 2b COVID-19 booster study with about 5,400 participants.
