2025 Annual Meeting of Shareholders

We currently plan to hold our 2025 Annual Meeting of Shareholders (the “2025 Annual Meeting”) on June 24, 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 scheduled date of the 2025 Annual Meeting is more than 30 days from the anniversary of the Company’s 2024 Annual Meeting of Stockholders, prior disclosed deadlines regarding the submission of stockholder proposals pursuant to Rule 14a-8 (“Rule 14a-8”) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), for the 2025 Annual Meeting are no longer applicable. The Company is hereby providing notice of certain revised deadlines for the submission of stockholder proposals in connection with the 2025 Annual Meeting. In order for a stockholder proposal, submitted pursuant to Rule 14a-8, to be considered timely for inclusion in the Company’s proxy statement and form of proxy for the 2025 Annual Meeting, such proposal must be received by the Company by April 8, 2025, which the Company determined to be a reasonable time before the Company plans to begin printing and mailing its proxy materials. Therefore, in order for a stockholder to submit a proposal for inclusion in the Company’s proxy materials for the 2025 Annual Meeting, the stockholder must comply with the requirements set forth in Rule 14a-8, including with respect to the subject matter of the proposal, and must deliver the proposal and all required documentation to the Company no later than April 8, 2025. The public announcement of an adjournment or postponement of the date of the 2025 Annual Meeting will not commence a new time period (or extend any time period) for submitting a proposal pursuant to Rule 14a-8.
