Magnera Corp

Pursuant to the Bylaws, any eligible shareholder, or group of no more than 20 eligible shareholders, that complies with certain informational disclosure requirements set forth in Sections 1.9(d) and 1.10 of our Bylaws, is permitted to include a director nominee or nominees (not to exceed 20% of the number of directors) in the Company’s proxy statement for its annual meeting.

In order to provide adequate time to assess shareholder-nominated candidates, requests to include shareholder-nominated candidates in the Company’s proxy materials must be received by the Company Secretary at the principal executive offices of the Company not less than 120 days nor more than 150 days prior to the first anniversary of the preceding year’s proxy statement mailing, subject to certain limited exceptions set forth in our Bylaws.

If no annual meeting was held in the preceding year, as was the case in 2025, a shareholder’s notice must be received the later of 90 days prior to the annual meeting or 10 calendar days after the meeting date is publicly disclosed. Accordingly, to be considered a timely notice for inclusion in this proxy statement, a shareholder notice must have been received by December 9, 2025 per the Current Report on Form 8-K filed with the SEC on November 28, 2025.
