Annual Meeting of Shareholders

Meeting Agenda:

Voting Matters and Vote Recommendation

Our Director Nominees

The following table provides summary information about each director nominee. Each director is elected annually by the affirmative vote of the holders of a plurality of the votes cast. Our Board, however, has adopted a majority vote policy, under which, in an uncontested election, any director nominee for whom the number of votes “withheld” exceeds the number of votes “for” the nominee must submit his or her resignation for consideration by our Nominating, Governance & Sustainability Committee and our Board.

Principal Accountant Fees and Services

As a matter of good corporate governance, we ask that our shareholders ratify the selection of PwC as our independent auditor for 2026. Set forth below is summary information with respect to 2025 auditor fees paid to PwC. See “Proposal 2 – Ratification of the Selection of Our Independent Auditor – Independent Auditing Firm Fees” for additional information.

Executive Compensation

We ask that our shareholders annually approve on an advisory basis our named executive officer (“NEO”) compensation. Our Board of Directors (the “Board”) recommends a FOR vote because it believes that our compensation policies and practices for named executive officers are effective in achieving the Company’s goals of rewarding sustained financial and operating performance and leadership excellence, aligning such executives’ long-term interest with those of our shareholders, and motivating our executives to remain with the Company for long and productive careers. At our most recent regularly held annual meeting, 96% of the votes cast by our shareholders approved our executive compensation.
