Mustang Bio, Inc. (“Mustang” or the “Company”) (Nasdaq: MBIO), a clinical-stage biopharmaceutical company focused on translating today’s medical breakthroughs in cell therapies into potential cures for difficult-to-treat cancers, today announced that it has entered into a definitive agreement for the exercise of certain existing warrants to purchase an aggregate of 16,877,638 shares of its common stock having an exercise price of $0.237 per share, originally issued in May 2024. The issuance or resale of the shares of common stock issuable upon exercise of the existing warrants are registered pursuant to an effective registration statement on Form S-1 (File No. 333-278006). The gross proceeds to the Company from the exercise of the existing warrants are expected to be approximately $4 million, prior to deducting placement agent fees and offering expenses payable by the Company.

H.C. Wainwright & Co. is acting as the exclusive placement agent for the offering.

In consideration for the immediate exercise of the existing warrants for cash, the Company will issue new unregistered warrants to purchase up to an aggregate of 33,755,276 shares of common stock. The new warrants will have an exercise price of $0.27 per share and will be exercisable commencing on the effective date of stockholder approval of the issuance of the shares issuable upon exercise of the new warrants (the “Stockholder Approval”).

The offering is expected to close on or about October 25, 2024, subject to satisfaction of customary closing conditions. Mustang currently intends to use the net proceeds from the offering for working capital and general corporate purposes.

The new warrants described above are being offered in a private placement under Section 4(a)(2) of the Securities Act of 1933, as amended (the “Securities Act”), and Regulation D promulgated thereunder and, along with the shares of common stock issuable upon exercise of the new warrants, have not been registered under the Securities Act, or applicable state securities laws. Accordingly, the new warrants issued in the private placement and the shares of common stock underlying the new warrants may not be offered or sold in the United States except pursuant to an effective registration statement or an applicable exemption from the registration requirements of the Securities Act and such applicable state securities laws. The Company has agreed to file a registration statement with the Securities and Exchange Commission covering the resale of the shares of common stock issuable upon the exercise of the new warrants.
