HUNT J B TRANSPORT SERVICES INC

We maintain controls and procedures designed to ensure that the information we are required to disclose in the reports we file with the SEC is recorded, processed, summarized and reported, within the time periods specified in the SEC rules, and that such information is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure. 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 our Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and operation of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended). Based upon that evaluation, our Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures were effective as of March 31, 2026.

There were no changes in our internal control over financial reporting during the first quarter 2026 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
