Item 8.01 Other Events.

 

Shuttle Pharmaceuticals Holdings, Inc. (the “Company”) is announcing the postponement of its previously announced special meeting of stockholders (the “Special Meeting”) from its currently scheduled date and time on Thursday, September 3, 2026, at 11:00 a.m. Eastern Time, to its new time on September 9, 2026, at 11:00 a.m. Eastern Time (the “Reconvened Special Meeting”). If you vote your proxy, your vote must be received by 11:59 p.m. Eastern Time on September 8, 2026 in order for your vote to be counted.

 

The Company decided to postpone the Special Meeting to allow for further time to solicit proxies from the Company’s stockholders, provide stockholders with additional time to consider to proposals and vote in order to facilitate broader participation, and to allow the Company’s stockholders additional time to consider the amendment to the terms of the Milestone Events described in the Company’s Current Report on Form 8-K filed with the Securities and Exchange Commission on September 1, 2026.

 

At the Reconvened Special Meeting, stockholders will be deemed to be present in person and vote at such adjourned meeting in the same manner as disclosed in the Definitive Proxy Statement on Schedule 14A for the Annual Meeting, as supplemented, filed by the Company with the U.S. Securities and Exchange Commission (“SEC”) on August 13, 2026. Valid proxies submitted prior to the Special Meeting will continue to be valid for the Reconvened Special Meeting, unless properly changed or revoked prior to votes being taken at the Reconvened Special Meeting.
