ArcBest Corporation announced amendments to its bylaws, introducing a "proxy access" provision that allows stockholders to nominate director candidates for inclusion in the company's proxy materials. Under the new rules, a stockholder or a group of up to 20 stockholders who collectively own at least 3% of ArcBest’s outstanding common stock for three consecutive years may nominate board candidates. The maximum number of nominees allowed is the greater of two or 25% of the board.

These amendments, approved by the Board of Directors on February 20, 2025, and effective immediately, are part of ArcBest’s Ninth Amended and Restated Bylaws. The full text of the revised bylaws is included as Exhibit 3.1 in the company's Form 8-K filing.

This move aligns ArcBest with evolving corporate governance trends, enhancing shareholder rights and engagement in board nominations.
