Subscription Agreement

On April 11, 2025, Alaunos Therapeutics, Inc., a Delaware corporation (the “Company”) entered into a Subscription Agreement (the “Agreement”), by and among the Company and Watermill Asset Management set forth on Appendix A thereto, pursuant to which the Company agreed to issue and sell, in a private offering to the Purchaser shares of Series A-1 Convertible Preferred Stock of the Company, par value of $0.001 per share (the “Series A-1 Preferred Stock”), at a price per share of $1,000 (the “Preferred Offering”) for an aggregate purchase price of $500,000. The Preferred Offering also relates to the offering of the shares of the Company's common stock (the "Common Stock") issuable upon the conversion of or otherwise pursuant to the terms of the Series A-1 Preferred Stock). The Preferred Offering closed on April 11, 2025.

Series A-1 Preferred Stock

On April 11, 2025, the Company filed with the Secretary of State of the State of Delaware the Certificate of Designation of Series A-1 Convertible Preferred Stock of the Company attached hereto as Exhibit 3.1 (the “Certificate of Designation”) and designated 1,000 shares of Series A-1 Preferred Stock.

Under the terms of the Certificate of Designation, each share of Series A-1 Preferred Stock has a stated value of $1,000 per share and, when issued, the Series A-1 Preferred Stock will be fully paid and non-assessable. The holders of Series A-1 Preferred Stock will be entitled to receive dividends at a rate of 10% per annum, payable in shares of Series A-1 Preferred Stock. In addition, the holders of Series A-1 Preferred Stock, to the extent any other dividends or distributions are declared for holders of the Common Stock, the holders of Series A-1 Preferred Stock will be entitled to participate in such dividends or distributions on an as-converted basis. The holders of Series A-1 Preferred Stock are entitled to vote alongside holders of Common Stock on an as-converted basis on a 1:1 ratio as Common Stock, voting together as a single class, with respect to any and all matters presented to the stockholders of the Company for their action. Each holder of Series A-1 Preferred Stock shall be entitled to a number of votes equal to the number of shares of Common Stock into which such holder’s shares of Series A-1 Preferred Stock are convertible pursuant to the Certificate of Designation as of the record date of such vote or written consent (or as otherwise required by applicable law).

Each holder of Series A-1 Preferred Stock has the right to convert all or any portion of the outstanding Series A-1 Preferred Stock held by such holder along with the aggregate accrued or accumulated and unpaid dividends thereon, at any time at such holder’s option, into shares of Common Stock in accordance with the terms of the Certificate of Designation.
