You will be able to participate, submit questions and vote your shares electronically at the Annual Meeting. At the Annual Meeting, you will be asked to:

1. Elect eleven directors for a one-year term expiring at the 2027 Annual Meeting of Stockholders; and

2. Ratify the appointment of PricewaterhouseCoopers LLP as our independent registered public accounting firm for the fiscal year ending December 31, 2026.

These matters are more fully discussed in the accompanying proxy statement. Our Board of Directors is soliciting proxies from stockholders who are entitled to vote at the Annual Meeting.
