We recommend that you log in a few minutes before the Annual Meeting start time of 1:00 p.m. Eastern Time on December 8, 2025, to ensure you are logged in when the Annual Meeting begins.

Pursuant to the bylaws of the Company, the Board of Directors has fixed the close of business on October 14, 2025, as the record date (the “Record Date”) for determination of stockholders entitled to notice and to vote at the Annual Meeting and any adjournment thereof. Holders of the Company’s Common Stock are entitled to vote at the Annual Meeting.

In accordance with rules and regulations adopted by the U.S. Securities and Exchange Commission (the “SEC”), we have elected to provide our beneficial owners and stockholders of record access to our proxy materials over the Internet. Beneficial owners are stockholders whose shares are held in the name of a broker, bank or other agent (i.e., in “street name”). Accordingly, a Notice of Internet Availability of Proxy Materials (the “Notice”) will be mailed on or about October 29,2025 to our beneficial owners and stockholders of record who owned our Common Stock at the close of business on October 14, 2025. Beneficial owners and stockholders of record will have the ability to access the proxy materials on a website referred to in the Notice or request a printed set of the proxy materials be sent to them by following the instructions in the Notice. Beneficial owners and stockholders of record who have previously requested to receive paper copies of our proxy materials will receive paper copies of the proxy materials instead of a Notice.

BY ORDER OF THE BOARD OF DIRECTORS

/s/ Geordan Pursglove

Chairman of the Board

Whether or not you expect to attend the Annual Meeting, please complete, date, sign and return the proxy mailed to you, or vote over the telephone or the internet as instructed in these materials, as promptly as possible in order to ensure your representation at the meeting. A return envelope (which is postage prepaid if mailed in the United States) has been provided for your convenience. Even if you have voted by proxy, you may still vote if you attend the Annual Meeting. Please note, however, that if your shares are held of record by a broker, bank or other nominee and you wish to vote at the Annual Meeting, you must obtain a proxy issued in your name from that record holder.
