This proxy statement supplement (this “Supplement”) provides updated information with respect to the 2025 Annual Meeting of Stockholders (the “Annual Meeting”)

Subsequent to the mailing of the Proxy Statement and as further described in the Company’s Current Report on Form 8-K as filed with the SEC on April 22, 2025,
Based on information provided by Marcum LLP (“Marcum”), the Company’s independent registered public accounting firm, on November 1, 2024, CBIZ CPAs P.C. (“CBIZ CPAs”) acquired the attest business of Marcum. On April 22, 2025, the Company was notified

public accounting firm for the year ending December 31, 2025.
As a result of the appointment of CBIZ CPAs appointment as the Company’s independent registered public accounting firm as successor to Marcum following CBIZ
