Beneficial Owner: Shares Registered in the Name of Broker, Financial Institution, or Other Nominee If, as of the close of business on April 22, 2025, the record date, your shares were held not in your name, but rather in an account at a brokerage firm, financial institution, or other similar organization, then you are the beneficial owner of shares held in “street name” and these proxy materials are being forwarded to you by that organization. The organization holding your account is considered to be the stockholder of record for purposes of voting at the Annual Meeting. As a beneficial owner, you have the right to direct your broker or other agent regarding how to vote the shares in your account. You should have received a proxy card and voting instructions with these proxy materials from that organization rather than from us. Simply complete and mail the proxy card and voting instructions to help ensure that your vote is counted. Alternatively, you may submit your voting instructions over the telephone or on the Internet as instructed by your broker, financial institution, or other nominee, if applicable. To attend the Annual Meeting and vote online during the Annual Meeting, you must obtain a valid proxy from your broker, financial institution, or other nominee. You will need the 16-digitcontrol number included in your proxy card or the instructions that accompanied your proxy materials. Follow the instructions from your broker, financial institution, or other nominee included with these proxy materials, or contact your broker, financial institution, or other nominee to request a proxy.
