Additional Matters for Consideration at the 2026 Annual Meeting

Please note the deadline for submission of proposals by shareholders for consideration at the 2026 Annual Meeting has passed. This applies to proposals that shareholders might wish to include in the Corporation’s Proxy Statement for the Annual Meeting (this Proxy Statement), proposals that shareholders might wish to include in their own proxy materials, which they would prepare, file with the SEC and disseminate to shareholders, or proposals that shareholders might wish to submit directly to a shareholder vote, in person, at the Annual Meeting. Therefore, no additional matters may be proposed by any shareholder for submission, or submitted, to a vote of the shareholders generally at the Annual Meeting, other than procedural issues such as adjournment, postponement or continuation. On such procedural issues, all shares represented at the Annual Meeting by proxy may be voted at the discretion of the attorneys-in-fact named in the proxies, to the extent permitted by law.

Proxy Cards Returned Without Specific Voting Instructions

Shares represented by properly executed proxies will be voted as directed. If you return a signed proxy card without specific voting instructions for any or all proposals, your shares will be voted “FOR” each of the Board’s four Director nominees on Proposal 1; “FOR” Say-On-Pay on Proposal 2; “FOR” ratification of the appointment of Crowe LLP on Proposal 3; and, “FOR” any other procedural matter properly submitted for shareholder consideration, in such manner as the shareholders’ attorneys-in-fact may determine, in their discretion, to be appropriate and in the best interests of shareholders generally.
