The United States Securities and Exchange Commission’s (the “SEC”) proxy rules set forth how companies must provide proxy materials. These rules are often referred to as “notice and access.” Under the notice and access model, a company may select either of the following options for making proxy materials available to stockholders: (i) the full set delivery option; or (ii) the notice only option. A company may use a single method for all its stockholders or use the full set delivery option for some stockholders and the notice only option for others.

Under the full set delivery option, a company delivers all proxy materials to its stockholders by mail or, if a stockholder has previously agreed, electronically. In addition to delivering proxy materials to stockholders, the company must post all proxy materials on a publicly accessible web site (other than the SEC’s web site) and provide information to stockholders about how to access that web site and the hosted materials. Under the notice only option, instead of delivering its proxy materials to stockholders, the company delivers a “Notice of Internet Availability of Proxy Materials” that outlines (i) information regarding the date and time of the meeting of stockholders, as well as the items to be considered at the meeting; (ii) information regarding the web site where the proxy materials are posted; and (iii) various means by which a stockholder can request printed or emailed copies of the proxy materials.

In connection with our 2024 Annual Meeting, we have elected to use the notice only option. Accordingly, you should have received a notice by mail, unless you requested a full set of materials from prior mailings, instructing you how to access proxy materials at www.proxyvote.com and providing you with a control number you can use to vote your shares. You may request that the Company also deliver to you printed or emailed copies of the proxy materials.

All shares represented by a valid proxy, timely submitted to the Company, will be voted. Where a proxy specifies a stockholder’s choice with respect to any matter to be acted upon, the shares will be voted in accordance with that specification. If no choice is indicated on the proxy, the shares will be voted as recommended by the Board. If your shares are registered under your own name, you may revoke your proxy at any time before the Annual Meeting by (i) delivering to the Corporate Secretary at the Company’s headquarters either a written instrument revoking the proxy or a duly executed proxy with a later date, or (ii) attending the Annual Meeting and voting online. If you hold shares in street name, through a broker, bank or other nominee, you must contact the broker, bank or other nominee to revoke your proxy.
