2025 Annual Meeting of Shareholders

We currently plan to hold our 2025 Annual Meeting of Shareholders (the “2025 Annual Meeting”) on or about December 16, 2025. The time and location of the 2025 Annual Meeting, and the matters to be considered, will be as set forth in our definitive proxy statement for the 2025 Annual Meeting to be filed with the SEC.

Because the expected date of the 2025 Annual Meeting represents a change of more than 30 calendar days from the date that was included in the proxy statement for the 2024 Annual Meeting of Shareholders as the expected date for the 2025 Annual Meeting, we are informing shareholders of this change and the updated deadline for shareholders to submit proposals intended for inclusion in our proxy statement for consideration at the 2025 Annual Meeting in accordance with the rules and regulations of the SEC. Accordingly, to be timely, shareholders wishing to submit proposals intended to be considered for inclusion in our proxy statement relating to the 2025 Annual Meeting must ensure that proper notice is received by us at our offices no later than the close of business on October 10, 2025, which we consider a reasonable time before we will begin printing and mailing proxy materials. Any proposal intended to be considered for inclusion in our proxy statement and form of proxy must comply with Rule 14a-8 of Regulation 14A under the Exchange Act. The submission of a shareholder proposal does not guarantee that it will be included in our proxy materials.
