Internet Availability of Proxy Materials

Internet Availability of Proxy Materials

As permitted by the rules of the SEC, we are using the internet as a means of furnishing proxy materials to our stockholders. We believe this method will make the proxy distribution process more efficient, lower costs and help in conserving natural resources.

On or about April 1, 2026, we mailed to our stockholders a Notice of Internet Availability of Proxy Materials containing instructions on how to access our proxy materials, including this Proxy Statement and our annual report. The Notice of Internet Availability of Proxy Materials also instructs you on how to access your proxy and voting instruction card to be able to vote through the internet or by telephone. Other stockholders, in accordance with their prior requests, and employees with regular access to email have received email notification of how to access our proxy materials and vote via the internet or by telephone or have been mailed paper copies of our proxy materials and a proxy and voting instruction card.

Important Notice Regarding the Availability of Proxy Materials for the Annual Stockholders Meeting To Be Held on May 13, 2026.

This Proxy Statement and annual report are available at www.proxyvote.com.
