**IMPORTANT NOTICE REGARDING THE AVAILABILITY OF PROXY MATERIALS FOR THE ANNUAL MEETING

OF STOCKHOLDERS TO BE HELD ON OCTOBER 15, 2025

In accordance with rules and regulations adopted by the Securities and Exchange Commission, we have elected to furnish our proxy materials to stockholders by providing access to the materials on the Internet. Accordingly, a Notice of Internet Availability of Proxy Materials (the “Internet Availability Notice”) has been mailed to the majority of our stockholders, while other stockholders will instead receive paper copies of the documents accessible on the Internet. We will first send and/or make available this Proxy Statement and the form of proxy for our 2025 Annual Meeting of Stockholders (the “Annual Meeting”) to our stockholders on or about September 4, 2025. It is important that your shares be represented and voted whether or not you plan to attend the Annual Meeting. If you are the registered holder of your shares and are viewing the proxy statement on the Internet, you may grant your proxy electronically via the Internet by following the instructions on the Internet Availability Notice previously mailed to you and the instructions listed on the Internet site. If you are receiving a paper copy of the proxy statement, you may vote by completing and mailing the proxy card enclosed with the proxy statement, or you may grant your proxy electronically via the Internet or by following the instructions on the proxy card. If your shares are held in “street name,” which means your shares are held of record by a broker, bank or other nominee, you should review the Notice of Internet Availability of Proxy Materials used by that firm to determine whether and how you will be able to submit your proxy over the Internet. Submitting a proxy over the Internet or by mailing a proxy card will ensure your shares are represented at the Annual Meeting. A complete list of stockholders entitled to vote at the Annual Meeting will be available for examination at our executive offices and during the Annual Meeting by following the instructions on the virtual platform.

You are cordially invited to attend the Annual Meeting virtually, via live webcast. Whether or not you expect to attend the Annual Meeting, please complete, date, sign and return the enclosed proxy or submit your proxy through the Internet, by mail as promptly as possible in order to ensure your representation at the Annual Meeting.
