Our Board of Directors currently consists of 12 members.

At the Annual Meeting, all directors will be elected to serve until the 2026 Annual Meeting, in each case, until their successors are elected and qualified, except for Mr. Farrell who submitted his resignation from his position as Chairman and a member of the Board effective as of the close of business on September 30, 2025 (the “Effective Date”). Our Board of Directors has nominated Bradlen S. Cashaw, Richard A. Dierker, Matthew T. Farrell, Bradley C. Irwin, Penry W. Price, Susan G. Saideman, Ravichandra K. Saligram, Robert K.

All nominees have agreed to be named in this proxy statement and to serve as directors if elected for an additional term, except for Mr. Farrell who will serve until the Effective Date.

The Board believes that contemporary governance practices suggest that the former CEO of a public company should continue to serve as a director for a limited transition period after retirement from the CEO role. Accordingly Mr. Farrell complied with the Board’s desire that he resign from the Board as of the Effective Date. Mr. Farrell’s decision to resign from the Board is not the result of any disagreement with the Company on any matter relating to the Company’s operations, policies or practices.
