December 31, 2026. For any proposal to be considered for inclusion in our proxy statement and form of proxy for submission to the shareholders at the 2026 Annual Meeting, it must be submitted in writing and comply with the requirements of Rule 14a-8 of the Exchange Act and our bylaws. Such proposals must be received at our offices at 640 Fifth Avenue, 14 Floor, New York, New York
