Vaxart Provides Business Update and Reports First Quarter 2026 Financial Results
Topline data from 400-person sentinel cohort of the Phase 2b COVID-19 trial anticipated in Q2 2026
Cash, cash equivalents, and investments of $61.0 million as of March 31, 2026; runway into second quarter of 2027
Live stockholder fireside chat scheduled for May 8, 2026 at 4:30 p.m. ET
SOUTH SAN FRANCISCO, Calif., May 7, 2026 — Vaxart, Inc. (OTCQX: VXRT) (“Vaxart" or the "Company”), a clinical-stage biotechnology company developing a range of oral recombinant pill vaccines based on its proprietary delivery platform, today announced its business update and financial results for the first quarter of 2026.
“In the first quarter of 2026, our team remained focused on the operational execution of our Phase 2b COVID-19 trial, which is being conducted in collaboration with BARDA,” said Steven Lo, Chief Executive Officer of Vaxart. “We are currently finalizing the topline 12-month safety and efficacy data from our 400-person sentinel cohort and are working to release these data as soon as our partnership protocols and contractual data-sharing guidelines permit. This cohort is expected to provide a descriptive analysis of the effect of our unique oral pill vaccine. The topline sentinel results will be followed by a more complete data readout on safety, immunogenicity, and efficacy from this sentinel cohort. In addition, we are dedicating significant resources to manage the 5,000-participant main study cohort, which is a primary focus of our clinical efforts. We anticipate the primary efficacy and safety data readout from this larger group in early 2027.”
Recent Business Highlights
COVID-19 Program Update
| |
●
|
Vaxart’s Phase 2b COVID-19 trial, conducted in collaboration with BARDA, compares the Company’s oral pill vaccine against a commercially available mRNA vaccine. The trial is fully enrolled with approximately 5,400 participants across the two cohorts – Vaxart’s oral pill vs. mRNA injectable.
|
| |
o
|
The Company is working toward the release of the 12-month safety and immunogenicity data from the 400-person sentinel cohort, which is now anticipated in the second quarter of 2026.
|
| |
■
|
The 400-participant sentinel cohort was designed to assess safety prior to initiating the larger efficacy and safety trial and was not powered to provide a statistically significant comparison between the oral pill and mRNA vaccine groups.
|
| |
■
|
In January 2025, Vaxart announced that an independent Data and Safety Monitoring Board (DSMB), which conducted a planned review of the 30-day safety data from the sentinel cohort of 400 participants, recommended that the study continue without any modifications.
|
| |
o
|
The primary data readout from the main KP.2 cohort of approximately 5,000 participants is currently anticipated in early 2027.
|
BARDA COVID-19 Contract Update
| |
●
|
As of March 31, 2026, Vaxart has received cumulative cash payments of $218.9 million associated with the BARDA contract awarded in 2024.
|
Norovirus
| |
●
|
As part of the characterization of its norovirus vaccine candidate, Vaxart is evaluating the cross-reactivity of its next generation bivalent product to GII.17 and other strains. These results are expected to be discussed in scientific meetings and potential scientific publications later in 2026.
|
Share Purchase Agreement
| |
●
|
On April 16, 2026, the Company entered into a share purchase agreement with Lincoln Park Capital Fund, LLC (“LPC”). This agreement provides Vaxart with the right, at its sole discretion, to sell up to $25 million of common stock over a 24-month period, subject to certain limitations and satisfaction of the conditions set forth in the agreement including registering in advance the resale of shares by LPC. This facility offers flexible access to capital to support the continued execution of the Company’s clinical milestones.
|
Board of Directors Appointment
| |
●
|
On April 23, 2026, Vaxart announced the appointment of Dr. James B. Breitmeyer, M.D., Ph.D., to its Board of Directors. Dr. Breitmeyer brings extensive experience in clinical development, including vaccines, and navigating complex regulatory pathways, further strengthening the Board's oversight as the Company advances its oral vaccine pipeline.
|
Corporate Headquarters Relocation
| |
●
|
Vaxart recently completed the relocation of its corporate headquarters. This move is designed to optimize the Company’s operational footprint and reduce fixed overhead expenses, further supporting its commitment to fiscal discipline and the efficient allocation of resources toward its clinical pipeline.
|
Financial Results for the First Quarter Ended March 31, 2026
| |
●
|
Cash, cash equivalents, and short-term investments totaled $61.0 million as of March 31, 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 first quarter of 2026 was $39.2 million, compared to $20.9 million for the first quarter of 2025. Revenue in the first quarter of 2026 and the first quarter of 2025 was primarily from government contracts related to the BARDA contract awarded in June 2024, with first quarter 2026 also including revenue recognized from the Dynavax license and collaboration agreement signed in November 2025, partially offset by a decrease in non-cash royalty revenue related to sale of future royalties.
|
| |
●
|
Research and development expenses were $29.4 million for the first quarter of 2026, compared to $30.7 million for the first quarter of 2025. The decrease is primarily due to a decrease in personnel costs, and clinical trial expenses related to Vaxart’s norovirus vaccine candidate as well as expenses related to manufacturing, preclinical, and facilities expenses, partially offset by an increase in clinical trial expenses related to Vaxart’s COVID-19 vaccine candidate.
|
| |
●
|
General and administrative expenses were $4.6 million for the first quarter of 2026, compared to $5.1 million for the first quarter of 2025. The decrease is primarily due to lower personnel costs and facility expenses, partially offset by an increase in legal and professional fees.
|
| |
●
|
Vaxart reported net income of $5.2 million for the first quarter 2026, compared to a net loss of ($15.6) million for first quarter of 2025. Net income per share for the first quarter of 2026 was $0.02, compared to a net loss per share of ($0.07) for the first quarter of 2025.
