## Item 3.01 Notice of Delisting or Failure to Satisfy a Continued Listing Rule or Standard; Transfer of Listing.
On February 21, 2025, Atossa Therapeutics, Inc. (the "Company") received a letter (the "Notice") from The Nasdaq Stock Market LLC ("Nasdaq") informing the Company that it was not in compliance with the minimum bid price requirements set forth in Nasdaq Listing Rule 5550(a)(2) for continued listing on Nasdaq, because the Company's common stock failed to maintain a minimum closing bid price of $1.00 per share for 30 consecutive business days. The Company's initial compliance period ended on August 20, 2025, and the Company subsequently requested an extension. On August 21, 2025, the Company was informed that its deadline to regain compliance was extended by 180 days, or until February 17, 2026

The Notice has no immediate effect on the listing or trading of the Company's common stock on Nasdaq. The Company intends to actively monitor the bid price for its common stock, and is committed to considering available options to regain compliance with the minimum bid price requirement, including, if necessary, potentially effectuating a reverse stock split.
