Vaxart (VXRT) faces Nasdaq delisting after reverse split plan withdrawn

Rhea-AI Filing Summary

Vaxart, Inc. reports that Nasdaq has decided to delist its securities after the company failed to meet conditions previously set by a Nasdaq Hearings Panel. Those conditions required shareholder approval of a reverse stock split by September 5, 2025, completion of the reverse split by October 6, 2025, and proof that the company met Nasdaq’s minimum bid price requirement. Vaxart withdrew its reverse stock split proposal on September 18, 2025, which left these conditions unmet.

Nasdaq’s Office of the General Counsel sent a letter on September 19, 2025 stating that Vaxart’s securities will be delisted. Trading of Vaxart’s common stock on Nasdaq has already been suspended since the open of trading on July 8, 2025. The company’s common stock is currently quoted on the OTCQX® Best Market under the symbol VXRT, meaning its shares continue to trade but no longer on a national securities exchange.

• Continued trading off-exchange: Vaxart’s common stock has been suspended from trading on Nasdaq since July 8, 2025 and is now quoted only on the OTCQX® Best Market under the symbol VXRT, which can reduce liquidity and market visibility.

Vaxart will be delisted from Nasdaq and now trades on OTCQX.

Vaxart confirms that Nasdaq will delist its securities after the company did not satisfy the Nasdaq Hearings Panel’s conditions. Those conditions included shareholder approval of a reverse stock split by September 5, 2025, completion of that split by October 6, 2025, and regaining compliance with the minimum bid price rule. Vaxart’s withdrawal of the reverse split proposal on September 18, 2025 effectively ensured noncompliance.

Nasdaq’s Office of the General Counsel sent a delisting letter on September 19, 2025, formalizing the outcome. Trading on Nasdaq had already been suspended since the open on July 8, 2025, so the practical shift to over-the-counter trading began earlier. The filing states that the common stock is now quoted on the OTCQX® Best Market under the symbol VXRT, which is a lower-profile venue than a national exchange.

For investors, this move from Nasdaq to OTCQX can affect trading liquidity and visibility, although the company’s shares remain tradeable. Future company filings may describe any additional steps Vaxart considers in response to the delisting and its prior reverse stock split proposal.
