BARDA COVID-19 Contract Update ● In June 2026, Vaxart announced a new contract modification to release additional funding from BARDA, through a contract with Advanced Technology International (“ATI”). The additional funding supports continuation of the Phase 2b COVID-19 study of our oral pill vaccine candidate and advances the next phase of data analysis. ● Following the modification, the total amount of authorized funding for the complete study is $344.8 million. Financial Results for the Second Quarter Ended June 30, 2026 ● Cash, cash equivalents, and short-term investments totaled $64.0 million as of June 30, 2026. Vaxart currently anticipates cash runway into the second quarter of 2027. The Company remains aggressive in exploring various strategies to extend its cash runway through business development partnerships and non-dilutive funding options, with the goal of achieving its upcoming clinical and regulatory milestones and maximizing stockholder value. ● Revenue for the second quarter of 2026 was $27.2 million, compared to $39.7 million for the second quarter of 2025. Revenue in the second quarter of 2026 and the second quarter of 2025 was primarily from government contracts related to the BARDA contract awarded in June 2024, with second quarter 2026 also including revenue recognized of $2.9 million from the Dynavax license and collaboration agreement signed in November 2025. ● Research and development expenses were $33.7 million for the second quarter of 2026, compared to $49.7 million for the second quarter of 2025.
