ITEM 3.01 – NOTICE OF DELISTING OR FAILURE TO SATISFY A CONTINUED LISTING RULE OR STANDARD; TRANSFER OF LISTING.

On March 3, 2025, ArcBest Corporation (the “Company”) received a notice from the staff of the Listing Qualifications Department (the “Staff”) of The Nasdaq Stock Market (“Nasdaq”) after the Company discovered and self-reported that it did not fully comply with the audit committee composition requirements set forth in Nasdaq Listing Rule 5605(c)(2)(A). The non-compliance was a result of Fredrik J. Eliasson, a member of the Audit Committee, not qualifying as independent pursuant to Nasdaq Listing Rule 5605(a)(2)(F) due to his brother-in-law serving as a partner of the Company’s outside auditor for the fiscal year ended December 31, 2024. Mr. Eliasson’s brother-in-law has never worked on the audit of the Company’s financial statements or performed any other services for the Company. Following discovery of this relationship, Mr. Eliasson promptly tendered his resignation as a member of the Audit Committee.

In its notice, the Staff determined that, as a result of the Company’s and Mr. Eliasson’s actions and subject to the Company complying with the disclosure requirements intended to be met by the filing of this Current Report on Form 8-K, the Company has regained compliance with Nasdaq Listing Rule 5605(c)(2)(A).

Signatures

Pursuant to the requirements of the Securities Exchange Act of 1934, the registrant has duly caused this report to be signed on its behalf by the undersigned hereunto duly authorized.
