Item 3.01 Notice of Delisting or Failure to Satisfy a Continued Listing Rule or Standard; Transfer of Listing.

On November 21, 2024, GT Biopharma, Inc. (the “Company”) received a letter (the “Letter”) from the Nasdaq Listing Qualifications Staff (the “Staff”) of The Nasdaq Stock Market LLC (“Nasdaq”) notifying the Company that its amount of stockholders’ equity has fallen below the $2,500,000 required minimum for continued listing set forth in Nasdaq Listing Rule 5550(b)(1). Nasdaq’s determination was based upon the Company’s stockholders’ equity as reported in the Company’s Quarterly Report on Form 10-Q for the period ended September 30, 2024. The Letter also noted that the Company does not meet the alternatives of market value of listed securities or net income from continuing operations, and therefore, the Company no longer complies with Nasdaq’s Listing Rules.

This Letter has no immediate effect on the listing of the Company’s common stock, and its common stock will continue to trade on The Nasdaq Capital Market under the symbol “GTBP” at this time.

Under Nasdaq Listing Rules, the Company has until January 6, 2025 to provide Nasdaq with a plan to achieve and sustain compliance. If Nasdaq accepts the Company’s plan to regain compliance, Nasdaq may grant an extension of up to 180 calendar days from the date of the Letter to evidence compliance. If Nasdaq does not accept the Company’s plan to regain compliance, the Company will have the opportunity to appeal the decision to a Nasdaq Hearings Panel.

The Company intends to submit to Nasdaq, within the requisite time period, a plan to regain compliance with Listing Rule 5550(b)(1). There can be no assurance that Nasdaq will accept the Company’s plan, that the Company will be able to regain compliance with Listing Rule 5550(b)(1) or that the Company will be able meet the continued listing requirements during any compliance period that may be granted by Nasdaq.
