Dear Stockholder:

It is my pleasure to inform you that our 2026 Annual Meeting of Stockholders (the “Annual Meeting”) will be conducted online on Wednesday, September 16, 2026, commencing at 10:00 a.m. ET.

Our Board of Directors will once again conduct the Annual Meeting as a virtual meeting because it believes that a virtual meeting will enable increased stockholder accessibility, while improving meeting efficiency and reducing costs. Stockholders will be able to listen, vote, and submit questions from their home or any remote location with Internet connectivity. Information on how to participate in the Annual Meeting can be found on page 3 of the Proxy Statement.

This year, we are once again taking advantage of the Securities and Exchange Commission rule that allows companies to provide their stockholders with access to proxy materials on the Internet. On or about August 7, 2026, we will begin mailing a Notice of Internet Availability of Proxy Materials (the “Notice”) to our stockholders informing them that our Proxy Statement, Annual Report for the fiscal year ended December 31, 2025 and voting instructions are available online. As more fully described in that Notice, all stockholders may choose to access our proxy materials on the Internet or may request to receive paper copies of the proxy materials. This allows us to conserve natural resources and reduces the costs of printing and distributing the proxy materials, while providing our stockholders with access to the proxy materials in a fast and efficient manner.

During the Annual Meeting, you will be asked to make your voice heard through (i) a vote on the election of five directors; (ii) a vote on the ratification of the appointment of Ernst & Young LLP as the Company’s independent registered public accounting firm for the fiscal year ending December 31, 2026; (iii) an advisory vote on executive compensation; (iv) an advisory vote on the frequency of future advisory votes on executive compensation; and (v) such other business as may properly come before the Annual Meeting and any adjournment or postponement thereof.

Whether or not you are able to participate in the Annual Meeting, it is important that your shares be represented. Please vote your shares using the Internet or the designated toll-free telephone number, or by requesting a printed copy of the proxy materials and completing and returning by mail the proxy card or voting instruction form you will receive in response to your request. Please refer to the section entitled “Voting Via the Internet, by Telephone, or by Mail” on page 2 of the Proxy Statement for a description of these voting methods.

Sincerely,

CAROLINE A. KOSTER

Corporate Secretary
