 shareholder may submit a proposal, including the nomination of Directors, for consideration at the 2026 Annual Meeting, but not for inclusion in next year’s proxy statement, if the shareholder gives timely written notice of such proposal in accordance with Regulation 8(c) or Regulation 12(b), as applicable, of our Regulations. In general, Regulation 8(c) and Regulation 12(b) provide that, to be timely, a shareholder’s notice must be delivered to or mailed and received by the Secretary at our principal executive offices not less than 90 nor more than 120 calendar days prior to the first anniversary of the date on which we first mailed our proxy materials for the preceding year’s Annual Meeting. If the date of the 2026 Annual Meeting is delayed by more than 60 calendar days after the anniversary of the Annual Meeting, then a shareholder’s notice must be delivered to our principal executive offices not later than the close of business on the later of the 90th calendar day prior to the 2026 Annual Meeting or the 10th calendar day following the day on which public announcement of the date of the 2026 Annual Meeting is first made.

Our proxy materials for the Annual Meeting will be released to shareholders beginning March 27, 2025. Ninety days prior to the first anniversary of this date will be December 27, 2025, and 120 days prior to the first anniversary of this date will be November 27, 2025. Our proxies for the 2026 Annual Meeting will confer discretionary authority to vote on any matter if we do not receive timely written notice of such matter in accordance with Regulation 8(c) or Regulation 12(b), as applicable. For business to be properly requested by a shareholder to be brought before the 2026 Annual Meeting, in addition to complying with the timeliness requirements set forth above, the shareholder must comply with all of the requirements of Regulation 8(c) or Regulation 12(b), as applicable, including, without limitation, with respect to the nomination of a director, a statement whether such shareholder intends to solicit the holders of shares representing at least 67% of the voting power of the Company's shares entitled to vote on the election of directors in support of director nominees other than Avient's nominees.
