EXPLANATORY NOTE

Celcuity Inc. (the “Company”) is filing this Amendment No. 1 on Form 8-K/A (this “Amendment”) to supplement the information provided in the Current Report on Form 8-K filed with the Securities and Exchange Commission on February 12, 2026. This Amendment sets forth the complete text of each amended item.

Item 5.02

Departure of Directors or Certain Officers; Election of Directors; Appointment of Certain Officers; Compensatory Arrangements of Certain Officers.

On February 11, 2026, the Board of Directors (the “Board”) of the Company, upon the recommendation of the Nominating and Corporate Governance Committee of the Board (the “N&CG Committee”), voted to increase the size of the Board from seven members to eight members and to appoint Charles (Chip) R. Romp as a new director to fill the resulting vacancy, effective immediately, for a term extending through the date of the Company’s 2026 Annual Meeting of Stockholders and the election of his successor, or his earlier death, resignation or removal. The Board determined that Mr. Romp qualifies as an independent director pursuant to the listing standards of The Nasdaq Stock Market LLC and the rules of the U.S. Securities and Exchange Commission (the “SEC”). On May 14, 2026, Mr. Romp was appointed by the Board to the Compensation Committee of the Board and the N&CG Committee, effective immediately.

Mr. Romp will receive compensation for his service in accordance with the Company’s non-employee director compensation program, which currently provides for an annual cash retainer of $70,000, payable quarterly, and an annual equity award with a fair market value of $135,000, payable in the form of restricted stock, stock options, or a combination of both, at the director’s election.

Upon appointment to the Board, the Company granted Mr. Romp a pro-rated annual grant of 215 shares of restricted stock under the Company’s 2017 Stock Incentive Plan, which vested in full on April 30, 2026.

There are no arrangements or understandings between Mr. Romp and any other persons pursuant to which Mr. Romp was selected as a director of the Company. There are no relationships or related transactions between Mr. Romp or any member of his immediate family and the Company that would be required to be reported under Item 404(a) of Regulation S-K.
