LANDSTAR SYSTEM INC

As of the end of the period covered by this quarterly report on Form 10-Q, an evaluation was carried out, under the supervision and with the participation of the Company’s management, including the Chief Executive Officer (“CEO”) and the Chief Financial Officer (“CFO”), of the effectiveness of the Company’s disclosure controls and procedures (as defined in Rule 13a-15(e) promulgated under the Securities Exchange Act of 1934, as amended). Based on that evaluation, the CEO and CFO concluded that the Company’s disclosure controls and procedures were effective as of June 27, 2026 to provide reasonable assurance that information required to be disclosed by the Company in reports that it filed or submitted under the Securities Exchange Act of 1934, as amended, is recorded, processed, summarized and reported within the time periods specified in Securities and Exchange Commission rules and forms.

There were no changes in the Company’s internal control over financial reporting during the second quarter of 2026, which were identified in connection with management’s evaluation required by paragraph (d) of Rules 13a-15 and 15d-15 under the Securities Exchange Act of 1934, as amended, that have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.

In designing and evaluating disclosure controls and procedures, Company management recognizes that any disclosure controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives, and management necessarily was required to apply its judgment in evaluating the cost-benefit relationship of possible controls and procedures. Because of the inherent limitation in any control system, no evaluation or implementation of a control system can provide complete assurance that all control issues and all possible instances of fraud have been or will be detected.
