SUPPLEMENT TO PROXY STATEMENT FOR

THE ANNUAL MEETING OF STOCKHOLDERS

To Be Held May 28, 2026

Explanatory Note

On April 14, 2026, Enveric Biosciences, Inc., a Delaware corporation (“we,” “us,” “our,” “Enveric,” or the “Company”), filed a definitive proxy statement (“Proxy Statement”) for its 2026 Annual Meeting of Stockholders (“Annual Meeting”), to be held at 10:00 a.m. Eastern Time on May 28, 2026. This supplement (“Supplement”) to the Proxy Statement supplements the Proxy Statement as filed and should be read in conjunction with the Proxy Statement and any other additional proxy materials we have filed.

The purpose of this Supplement is to correct typographical errors with respect to the maximum ratio of the proposed reverse stock split range in Proposal 3. Proposal 3 in the Proxy Statement requests stockholder approval to extend the approval of the Board of Directors (the “Board”) to amend the Company’s Amended and Restated Certificate of Incorporation, as amended, to, at the discretion of the Board, effect a reverse stock split with respect to the Company’s issued and outstanding common stock, including stock held by the Company as treasury shares, at a ratio of 1-for-5 to 1-for-15 (the “Range”), with the ratio within such Range to be determined at the discretion of the Board and included in a public announcement. In two locations within the Proxy Statement, and specifically on the proxy card (“Proxy Card”) and in the notice of Internet availability (“Notice”) that were mailed to stockholders, the maximum ratio of the proposed reverse stock split range was incorrectly stated at 1-for-50. The correct maximum ratio intended by the Board, and which was accurately stated in the text of Proposal 3 within the Proxy Statement itself, starting on page 34, is 1-for-15.

THIS SUPPLEMENT SHOULD BE READ IN CONJUNCTION WITH THE PROXY STATEMENT.

EXCEPT AS SPECIFICALLY SUPPLEMENTED BY THE INFORMATION CONTAINED HEREIN, THIS SUPPLEMENT DOES NOT MODIFY ANY OTHER INFORMATION SET FORTH IN THE PROXY STATEMENT.

This Supplement supplements and updates the disclosures in the Proxy Statement as follows:

● All references in the Proxy Statement to “1-for-50” are replaced with “1-for-15”.

● The foregoing updates apply to the Proxy Card and Notice. The entirety of the revised Proxy Card and Notice are reproduced below:
