Entry into a Material Definitive Agreement

On February 19, 2026, Moleculin Biotech, Inc. (the "Company") entered into warrant exercise inducement offer letters (each, an "Inducement Letter") with holders of certain existing warrants (the "Holders") to purchase up to 2,122,652 shares of Company common stock with an exercise price of $3.90 per share (the "Existing Warrants").

Pursuant to the Inducement Letter, the Holders agreed to exercise the Existing Warrants, and the Company agreed to issue the Holders new warrants to purchase up to a number of shares of Company common stock equal to 300% of the number of shares of Company common stock underlying the exercised Existing Warrants, comprised of new Series H warrants to purchase up to 6,367,956 shares of Company common stock (the "Inducement Warrants" and the shares of Company common stock underlying the Inducement Warrants, the "Inducement Warrant Shares") with an exercise term of five years from the initial exercise date.

The issuance and/or resale of the shares of Company common stock underlying the Existing Warrants have been registered pursuant to effective registration statements on Form S-1 (File No. 333-287727) and Form S-3 (File No. 333-290418). The Company anticipates receiving aggregate gross proceeds of up to approximately $8.3 million from the exercise of the Existing Warrants before deducting fees and other expenses payable by it.

Each Inducement Warrant has an initial exercise price per share equal to the lesser of (i) $3.90, and (ii) the lowest volume weighted average price of the Company common stock on any trading day during the five trading day period immediately following the public announcement of the Company entering into the Inducement Letters with the Holders, will be exercisable upon the receipt of shareholder approval of the issuance of the Inducement Warrant Shares, and may be exercised for a period of five years from such approval. If while the Inducement Warrants are outstanding, the Company issues or sells, or is deemed to have issued or sold, any common stock and/or common stock equivalents other than in connection with certain exempt issuances, at a purchase price per share less than the exercise price of the Inducement Warrants in effect immediately prior to such issuance or sale or deemed issuance or sale, then immediately after such issuance or sale or deemed issuance or sale, the exercise price of the Inducement Warrants then in effect will be reduced to an amount equal to the new issuance price, subject to a floor price of $0.962.

The Inducement Warrants may only be exercised on a cashless basis if there is no registration statement registering, or the prospectus contained therein is not available for, the resale of the shares of common stock underlying the Inducement Warrants by the Holders. The Holders of an Inducement Warrant may not exercise any such warrants to the extent that such exercise would result in the number of shares of common stock beneficially owned by such Holders and its affiliates exceeding 4.99% or 9.99% (at the election of the Holders) of the total number of shares of common stock outstanding immediately after giving effect to the exercise, which percentage may be increased or decreased at the Holders’ election not to exceed 9.99% (the "Beneficial Ownership Limitation"). In the event of certain fundamental transactions (as defined in the Inducement Warrants), the Holders of the Inducement Warrants will have the right to receive the Black Scholes value of the Inducement Warrants calculated pursuant to a formula set forth in the Inducement Warrants, payable either in cash or in the same type or form of consideration that is being offered and being paid to the Holders of common stock.

The Company agreed to file a registration statement on Form S-3 (or other appropriate form, including Form S-1, if it is not then Form S-3 eligible) providing for the resale of the Inducement Warrant Shares issuable upon the exercise of the Inducement Warrants (the "Resale Registration Statement"), on or before March 31, 2026, and to use commercially reasonable efforts to have such Resale Registration Statement declared effective by the SEC by April 30, 2026 and to keep the Resale Registration Statement effective at all times until no Holders of the Inducement Warrants own any Inducement Warrant Shares.

Roth Capital Partners, LLC served as financial advisor for the transaction and received as compensation for such services a fee of 7.0% of the gross proceeds the Company received from the warrant inducement of the Existing Warrants and reimbursement of $50,000 in legal fees.

The representations, warranties and covenants contained in the Inducement Letter were made solely for the benefit of the parties to the Inducement Letter. In addition, such representations, warranties and covenants: (i) are intended as a way of allocating the risk between the parties to such agreements and not as statements of fact, and (ii) may apply standards of materiality in a way that is different from what may be viewed as material by stockholders of, or other investors in, the Company. Accordingly, the Inducement Letter is filed with this report only to provide investors with information regarding the terms of transaction, and not to provide investors with any other factual information regarding the Company. Information concerning the subject matter of the representations and warranties may change after the date of the Inducement Letter, which subsequent information may or may not be fully reflected in public disclosures.

The forms of the Inducement Warrant and Inducement Letter are filed as Exhibits 4.1 and 10.1, respectively, to this Current Report on Form 8-K. The foregoing summaries of the terms of these documents are subject to, and qualified in their entirety by, such documents, which are incorporated herein by reference.
