LANDSTAR SYSTEM INC

Disclosure Controls and Procedures

As of the end of the period covered by this Annual Report on Form 10-K, an evaluation was carried out, under the supervision and with the participation of the Company’s management, including the Chief Executive Officer (“CEO”) and 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 December 28, 2024 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.

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.

Internal Control Over Financial Reporting

(a) Management’s Report on Internal Control over Financial Reporting

Management of Landstar System, Inc. (the “Company”) is responsible for establishing and maintaining effective internal control over financial reporting, as such term is defined in Rules 13a-15(f) and 15d-15(f) under the Securities Exchange Act, as amended.

Internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. The Company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the Company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the Company are being made only in accordance with authorizations of management and directors of the Company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the Company’s assets that could have a material effect on the Company’s financial statements.

Management, with the participation of the Company’s principal executive officer and principal financial officer, assessed the effectiveness of the Company’s internal control over financial reporting as of December 28, 2024. This assessment was performed using the criteria established under the Internal Control-Integrated Framework (2013) established by the Committee of Sponsoring Organizations of the Treadway Commission (“COSO”).

Internal control over financial reporting cannot provide absolute assurance of achieving financial reporting objectives because of its inherent limitations, including the possibility of human error or circumvention or overriding of internal control. Accordingly, even effective internal control over financial reporting can provide only reasonable assurance with respect to financial statement preparation and reporting and may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Based on the assessment performed using the criteria established by COSO, management has concluded that the Company maintained effective internal control over financial reporting as of December 28, 2024.
