Item 5.03. Amendments to Articles of Incorporation or Bylaws; Change in Fiscal Year.

As described in Item 5.07 of the Current Report, at the 2026 annual meeting of shareholders (the “2026 Annual Meeting”) of Post Holdings, Inc. (the “Company”) held on January 29, 2026, the Company’s shareholders approved three amendments (collectively, the “Articles Amendments”) to the Company’s prior Amended and Restated Articles of Incorporation (the “Prior Articles,” and the Prior Articles and the Revised Articles (defined below) are collectively referred to as the “articles of incorporation”) to lower certain supermajority voting thresholds, as described in “Amendments to the Company’s Amended and Restated Articles of Incorporation to Eliminate Certain Supermajority Voting Requirements (Proxy Item No. 4)” of the Company’s Definitive Proxy Statement on Schedule 14A filed with the Securities and Exchange Commission on December 15, 2025 (the “Proxy Statement”).

The Articles Amendments consisted of (i) an amendment to eliminate the supermajority voting requirement relating to the removal of directors, (ii) an amendment to eliminate the supermajority voting requirement relating to the approval of certain business combinations with interested shareholders and (iii) an amendment to eliminate the supermajority voting requirement relating to amendments to the provisions regarding the approval process for certain business combinations with interested shareholders, all as described under Proposals 4(a), 4(b) and 4(c) in Item 5.07 of the Current Report, which are incorporated by reference into this Item 5.03.

The Articles Amendments were previously approved by the Company’s Board of Directors (the “Board”), subject to shareholder approval. The Articles Amendments became effective upon the filing of the Company’s revised Amended and Restated Articles of Incorporation, which incorporated the Articles Amendments (the “Revised Articles”), with the Secretary of State of the State of Missouri on January 29, 2026.

The foregoing description of the terms of the Articles Amendments does not purport to be complete and is qualified in its entirety by reference to the Revised Articles, a copy of which is filed as Exhibit 3.1 to the Current Report and a marked copy of which showing the amendments is filed as Exhibit 3.2 to the Current Report, both of which are incorporated herein by reference.
