RUSH ENTERPRISES INC \TX\

The Company, under the supervision and with the participation of management, including the Company’s principal executive officer and chief financial officer, evaluated the effectiveness of our disclosure controls and procedures as of the end of the period covered by this report. Based on that evaluation, the principal executive officer and chief financial officer concluded that our disclosure controls and procedures were effective as of September 30, 2026, to ensure that information required to be disclosed in the reports filed or submitted under the Securities Exchange Act of 1934 is (i) recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commission’s rules and forms, and (ii) is accumulated and communicated to Company management, including the principal executive officer and chief financial officer, as appropriate, to allow timely decisions regarding required disclosure.

There has been no change in our internal control over financial reporting that occurred during the three months ended September 30, 2026 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.
