(To Prospectus dated May 7, 2025)

Tevogen Bio Holdings Inc.

This prospectus supplement updates and supplements the prospectus, dated May 7, 2025 (as supplemented to date, the “Prospectus”), which forms a part of our registration statement on Form S-1 (No. 333-280414), as amended. This prospectus supplement is being filed to update and supplement the information in the Prospectus with the information contained in our Current Report on Form 8-K filed with the Securities and Exchange Commission on March 25, 2026 (the “Form 8-K”). Accordingly, we have attached the Form 8-K to this prospectus supplement.

This prospectus supplement should be read in conjunction with the Prospectus, which is to be delivered with this prospectus supplement, and is qualified by reference thereto, except to the extent that the information in this prospectus supplement updates or supersedes the information contained in the Prospectus. Please keep this prospectus supplement with your Prospectus for future reference.

Our common stock, par value $0.0001 per share (“Common Stock”), and public warrants to purchase Common Stock (“Warrants”) are listed on The Nasdaq Stock Market LLC under the symbols “TVGN” and “TVGNW,” respectively. On March 24, 2026, the closing price of our Common Stock was $5.22 and the closing price for our Warrants was $0.0346.

We are an “emerging growth company” and “smaller reporting company” for purposes of federal securities laws and are subject to reduced public company reporting requirements. Accordingly, the information in the Prospectus and this prospectus supplement may not be comparable to information provided by companies that are not emerging growth companies or smaller reporting companies.

Our business and investment in our Common Stock and Warrants involve significant risks. These risks are described in the section titled “Risk Factors” beginning on page 8 of the Prospectus.

Neither the Securities and Exchange Commission nor any state securities commission has approved or disapproved of these securities or passed upon the adequacy or accuracy of the Prospectus or this prospectus supplement. Any representation to the contrary is a criminal offense.

The date of this prospectus supplement is March 25, 2026.
