As further described below in Item 5.07 of this Current Report on Form 8-K, the Annual Meeting of Stockholders (the “Annual Meeting”) of Knife River Corporation (the “Company”) was held on May 22, 2025, at which the Company’s stockholders approved the amendment and restatement of the Company’s Amended and Restated Certificate of Incorporation to eliminate the two-thirds (662/3%) supermajority voting requirements and make other immaterial, non-substantive and ministerial changes (as amended and restated, the “Second Amended and Restated Certificate of Incorporation”), as further set forth in the Company’s Definitive Proxy Statement for the Annual Meeting of the Company filed with the Securities and Exchange Commission on April 7, 2025 (the “Proxy Statement”).

On May 22, 2025, following the conclusion of the Annual Meeting of the Company, the Company filed the Second Amended and Restated Certificate of Incorporation with the Secretary of State of the State of Delaware, which became effective upon filing.

In connection with the approval by the Company’s stockholders of the Second Amended and Restated Certificate of Incorporation and the Company’s related filing of the Second Amended and Restated Certificate of Incorporation with the Secretary of State of the State of Delaware, on May 22, 2025, the Board of Directors of the Company amended and restated the Company’s Amended and Restated Bylaws (as amended and restated, the “Second Amended and Restated Bylaws”), effective as of that date, to similarly remove the related two-thirds (662/3%) supermajority voting requirements to align with the Second Amended and Restated Certificate of Incorporation, as well as make other immaterial, non-substantive and ministerial changes.

The foregoing summaries of the Second Amended and Restated Certificate of Incorporation and the Second Amended and Restated Bylaws are qualified in their entirety by reference to the full text of the Second Amended and Restated Certificate of Incorporation and the Second Amended and Restated Bylaws, copies of which are filed as Exhibit 3.1 and Exhibit 3.2, respectively, to this Current Report on Form 8-K, and incorporated herein by reference.
