Effective as of July 1, 2024, the Company became a fully remote company. We do not maintain a principal executive office. For purposes
of compliance with applicable requirements of the Securities Act of 1933, as amended, and the Securities Exchange Act of 1934, as amended,
any stockholder communication required to be sent to the Company’s principal executive offices may be directed to
Item 3.01 Notice of Delisting or Failure to Satisfy a Continued Listing Rule or Standard.
On May 20, 2026, GT Biopharma, Inc., a Delaware corporation (the “Company”), received a letter from the Nasdaq Listing Qualifications Staff (the “Staff”) of The Nasdaq Stock Market LLC (“Nasdaq”) notifying the Company that the Staff has granted the Company an additional compliance period of 180 calendar days, or until November 16, 2026, to regain compliance with Nasdaq Listing Rule 5550(a)(2), which requires listed securities to maintain a minimum bid price of $1.00 per share (the “Minimum Bid Price Requirement”). If at any time during this additional compliance period the closing bid price of the Company’s common stock, $0.001 par value per share (the “Common Stock”), is at least $1.00 per share for a minimum of 10 consecutive business days (unless the Staff exercises its discretion to extend this ten business day period pursuant to Nasdaq Listing Rule 5810(c)(3)(H)), Nasdaq will provide the Company written confirmation of compliance with the Minimum Bid Price Requirement, and the matter will be closed.
As previously disclosed, on November 20, 2025, the Company received a letter from the Staff notifying the Company that the closing bid price of the Company’s common stock had fallen below the required minimum bid price of $1 per share for 30 consecutive business days and that the Company had been provided an initial 180 calendar day compliance period, or until May 19, 2026, to regain compliance.
Nasdaq determined that the Company is eligible for the additional compliance period because the Company meets the continued listing requirement for the market value of publicly held shares and all other applicable requirements for initial listing on the Nasdaq Capital Market, with the exception of the Minimum Bid Price Requirement.
The Company intends to monitor the closing bid price of the Common Stock and assess its available options to regain compliance with the Minimum Bid Price Requirement and continue listing on The Nasdaq Capital Market. There can be no assurance that the Company will be able to regain compliance with the Minimum Bid Price requirement or will otherwise be in compliance with other applicable Nasdaq listing rules.
