Accordingly, business proposals for the 2026 annual meeting of stockholders must be delivered to the Secretary not earlier than the close of business on February 12, 2026 and not later than the close of business on March 14, 2026.

•Enhance disclosure requirements in connection with stockholder nominations of directors and submissions of proposals regarding other business at stockholder meetings, including, without limitation, requiring certain additional background and ownership information and disclosures regarding proposing and nominating stockholders and other persons related to or participating in a stockholder’s solicitation of proxies.

•Require stockholder nominees to complete a questionnaire to provide certain background information and representation and representations regarding disclosure of voting or compensation arrangements, compliance with the Company’s policies and guidelines and intent to serve the entire term.

•Add procedural mechanics for stockholders to call special meetings of stockholders or act by written consent.

•Update provisions relating to calling and notices of special Board meetings.

•Clarify procedures for director and officer resignations.

•Update procedures governing stock transfers and record date setting.
