Subsequent Events [Abstract] |
Subsequent Events | Note 11 – Subsequent Events Stock Offering On January 4, 2023, GT Biopharma received gross proceeds of $6.5 million, before deducting placement agent fees and other offering expenses of approximately $450,000, in relation to a purchase agreement (the “Purchase Agreement”) signed on December 30, 2022, between the Company and an institutional investor (the “Purchaser”) for the issuance and sale, in a registered direct offering (the “Offering”), of 3,600,000 shares of the Company’s common stock, par value $0.001 per share (the “Shares”), pre-funded warrants to purchase up to 2,900,000 shares of the Company’s common stock (the “Pre-Funded Warrants”), and warrants to purchase up to an aggregate of 6,500,000 shares of the Company’s common stock (the “Common Warrants”). The Common Warrants have an exercise price equal to $1.00, will be exercisable commencing six months following issuance, and will have a term of exercise equal to five years following the initial exercise date. The Pre-Funded Warrants have an exercise price of $0.0001 per Share, are immediately exercisable and can be exercised at any time after their original issuance until such Pre-Funded Warrants are exercised in full. The Shares and Common Warrants were sold at an offering price of $1.00 per Share and accompanying Common Warrant and the Pre-Funded Warrants and Common Warrants were sold at an offering price of $0.9999 per Pre-Funded Warrant and accompanying Common Warrant. Issuance of Common Stock for research and development agreement On March 14, 2023, the Company issued 486,819 shares of common stock with a fair value of $820,341 pursuant to a payment agreement with a third-party manufacturer (see Note 4). The shares were valued at the respective month-end closing prices of the Company’s common stock when the payment was due to the vendor. Demand Letter In March 2023, the Company received a demand letter from an attorney representing an alleged holder of a convertible note which alleges that the Company did not deliver shares of common stock that were due on conversion in 2022. The demand letter contends that the Company is liable for per diem liquidated damages. The Company has denied liability and will defend any such claim vigorously if asserted.
