Item 3.02 Unregistered Sales of Equity Securities.

 

As previously disclosed, on September 9, 2026, Shuttle Pharmaceuticals Holdings, Inc. (the “Company”) held a Special Meeting of Stockholders (the “Meeting”) pursuant to which, among other things, the stockholders of the Company approved the issuance of securities of the Company as described in that Definitive Proxy Statement on Schedule 14A filed by the Company with the U.S. Securities and Exchange Commission (the “SEC”) on August 13, 2026, as supplemented (the “Proxy Statement”). The voting results of the Meeting were reported on a Current Report on Form 8-K filed with the SEC on September 11, 2026.

 

As of September 14, 2026, the Company issued an aggregate of (a) 2,869,595 shares of the Company’s common stock, par value $0.00001 per share (“Common Stock”), upon the conversion of certain of its issued and outstanding shares of Series B-1 Preferred Stock (the “B-1 Preferred Stock”) and (b) 867,887 shares of Common Stock upon the conversion of certain of its issued and outstanding shares of Series B-2 Preferred Stock (the “B-2 Preferred Stock” and with the B-1 Preferred Stock, the “Preferred Stock”). The issuance of such shares of Common Stock takes into account the 4.99% beneficial ownership limitations set forth in the Preferred Stock. Also as a result of the approval of the issuance of securities of the Company as described in the Proxy Statement, as of September 9, 2026, the Company issued common stock purchase warrants (the “Warrants”) to purchase an aggregate of approximately 927,114 shares of Common Stock exercisable for a period of three years at an exercise price of $10.30 per share (post-reverse split), and pre-funded warrants (the “Pre-Funded Warrants”) to purchase an aggregate of approximately 16,932,508 shares of Common Stock.

 

Copies of the form of Warrant and form of Pre-Funded Warrant were filed as Exhibits 4.1 and 4.2, respectively, to the Company’s Current Report on Form 8-K filed with the SEC on May 1, 2026, and are incorporated herein by reference, and the foregoing description of the Warrants and Pre-Funded Warrants is qualified in its entirety by reference thereto.

 

The issuance of the securities set forth in this Item 3.02 has not been registered under the Securities Act of 1933, as amended (the “Securities Act”), in reliance upon the exemption from registration provided by Section 4(a)(2) of the Securities Act.
