(a) Dismissal of Independent Registered Public Accounting Firm

On March 13, 2026, the Audit Committee of the Board of Directors of Universal Logistics Holdings, Inc. (the “Company”) approved the dismissal of Grant Thornton LLP (“Grant Thornton”) as the Company’s independent registered public accounting firm, effective upon the Company’s filing of its Form 10-K for the fiscal year ending December 31, 2025, which occurred on March 16, 2026.

Grant Thornton’s audit reports on the Company’s consolidated financial statements for the fiscal years ended December 31, 2025 and December 31, 2024 did not contain an adverse opinion or a disclaimer of opinion, and were not qualified or modified as to uncertainty, audit scope, or accounting principles.

During the Company’s fiscal years ended December 31, 2025 and December 31, 2024, and subsequent interim period through March 16, 2026, there were no disagreements (as defined in Item 304(a)(1)(iv) of Regulation S-K) between the Company and Grant Thornton on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedures that, if not resolved to Grant Thornton’s satisfaction, would have caused Grant Thornton to make reference to the matter in its reports on the Company’s consolidated financial statements.

During the Company’s fiscal years ended December 31, 2025 and December 31, 2024, and subsequent interim period through March 16, 2026, there were no reportable events as defined in Item 304(a)(1)(v) of Regulation S-K except for the previously disclosed material weakness in the Company’s internal control over financial reporting related to deficiencies in the Company’s controls over financial reporting and financial statement preparation, including insufficient personnel with appropriate technical accounting expertise and ineffective controls over the identification, review and approval of complex accounting transactions and financial statement disclosures related to changes within our business described in the Company’s filings with the Securities and Exchange Commission. The registrant has authorized Grant Thornton to respond fully to the inquiries of the successor auditor concerning the subject matter of this reportable event.

The Company has provided Grant Thornton with a copy of the foregoing disclosures and has requested that Grant Thornton furnish the Company with a letter addressed to the Securities and Exchange Commission stating whether it agrees with the statements made in this Item 4.01(a). A copy of Grant Thornton’s letter is filed as Exhibit 16.1 to this Current Report on Form 8-K.
