Information about the Company’s directors and executive officers is available in the Company’s registration statement on Form S-1/A, which was filed with the SEC on April 24, 2026. To the extent holdings of the Company’s securities by their respective directors or executive officers have changed since the amounts set forth in the Registration Statement on Form S-1/A, such changes have been or will be reflected on Initial Statements of Beneficial Ownership on Form 3 or Statements of Change in Ownership on Form 4 filed with the SEC.

Although the Company has attempted to identify important factors that could cause actual results to differ materially from those described in forward-looking statements and forward-looking information, there may be other factors that cause results not to be as anticipated, estimated or intended.
