Annual Meeting of Stockholders

IMPORTANT INFORMATION REGARDING DELIVERY OF PROXY MATERIALS

The Securities and Exchange Commission (the “SEC”) has adopted rules regarding how companies must provide proxy materials to their stockholders. These rules are often referred to as “notice and access,” under which a company may select either of the following options for making proxy materials available to its stockholders:

• the full set delivery option; or

• the notice only option.

A company may use a single method for all of its stockholders or use full set delivery for some while adopting the notice only option for others. In connection with our 2025 Annual Meeting of Stockholders (the “2025 Annual Meeting”), we have elected to use the notice only option.

#### Full Set Delivery Option
Under the full set delivery option, which we have elected NOT to use for the 2025 Annual Meeting, a company delivers all proxy materials to its stockholders by mail. In addition to delivery of proxy materials to stockholders, the company must post all proxy materials on a publicly-accessible website and provide information to stockholders about how to access the website. Although we have elected to use the notice only option in connection with the 2025 Annual Meeting, we may choose to use the full set delivery option in the future.

#### Notice Only Option
Under the notice only option, a company must post all proxy materials on a publicly-accessible website. Instead of delivering proxy materials to its stockholders, the company instead delivers a “Notice of Internet Availability of Proxy Materials.” The notice includes, among other things:

• information regarding the date and time of the 2025 Annual Meeting of stockholders as well as the items to be considered at the meeting;
