HEARTLAND EXPRESS INC

Evaluation of Disclosure Controls and Procedures– We have established disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) to ensure that material information relating to us, including our consolidated subsidiaries, is made known to the officers who certify our financial reports and to other members of senior management and the Board of Directors.

As of the end of the period covered by this report, we carried out an evaluation, under the supervision and with the participation of our management, including the Chief Executive Officer (Principal Executive Officer) and Chief Financial Officer (Principal Accounting and Financial Officer), of the effectiveness of the design and operations of our disclosure controls and procedures. Based upon that evaluation, our Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures were effective as of June 30, 2024.

Our management, including our Chief Executive Officer and Chief Financial Officer, does not expect that our disclosure controls and procedures, or our internal controls, will prevent all errors or intentional fraud. An internal control system, no matter how well-conceived and operated, can only provide reasonable, not total, assurance that the objectives of such internal controls are met.

Changes in Internal Control Over Financial Reporting – There have been no changes in our internal control over financial reporting that occurred during the quarter ended June 30, 2024, that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
