Amendment Description This Amendment No. 1 on Form 10-K/A (“Amendment No. 1”) is being filed solely to revise the Exhibit Index, contained in Part IV, Item 15 of the Annual Report on Form 10-K for the fiscal year ended December 31, 2024 (the “Original 2024 10-K”) of GT Biopharma, Inc. (the “Company”), filed with the Securities and Exchange Commission (the “SEC”) on February 21, 2025, to include the Company’s Compensation Recovery Policy as Exhibit 97.1.Pursuant to Rule 12b-15 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), currently dated Exhibit 31 certifications are filed herewith as exhibits to this Amendment No. 1 pursuant to Rule 13a-14(a) or 15d-14(a) of the Exchange Act under Item 15(a) of Part IV hereof. Because no financial statements have been included in this Amendment No. 1 and this Amendment No. 1 does not contain any disclosure with respect to Items 307 and 308 of Regulation S-K, paragraphs 3, 4, and 5 of the certifications have been omitted. Similarly, because no financial statements have been included in this Amendment No. 1, currently dated Exhibit 32 certifications pursuant to Section 906 of the Sarbanes-Oxley Act of 2002 have been omitted.  Amendment No. 1 speaks as of the filing date of the Original 2024 10-K, and does not reflect events that may have occurred subsequent to the filing date of the Original 2024 10-K. Except as described above, no other changes have been made to the Original 2024 10-K, and Amendment No. 1 does not modify, amend or update in any way any of the financial or other information contained in the Original 2024 10-K. Amendment No. 1 should be read in conjunction with the Original 2024 10-K and the Company’s other filings with the SEC.
