Item 9A. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

As of August 29, 2026, an evaluation was performed under the supervision and with the participation of AutoZone’s management, including the Chief Executive Officer and the 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 Exchange Act, as amended. Based on that evaluation, our management, including the Chief Executive Officer and the Chief Financial Officer, concluded that our disclosure controls and procedures were effective as of August 29, 2026.

Internal Control Over Financial Reporting

A report of AutoZone’s management on our internal control over financial reporting (as such term is defined in Rule 13a-15(f) under the Exchange Act) and a report of Ernst & Young, LLP, an independent registered public accounting firm, on the effectiveness of AutoZone’s internal control over financial reporting are included in Part II, Item 8 of this document and is incorporated herein by reference.

Changes in Internal Control Over Financial Reporting

As part of a multi-year system implementation, the Company began utilizing certain aspects of a new enterprise resource planning (“ERP”) system during the quarter ended February 14, 2026. Eventually, this ERP system will replace our existing core financial systems. The ERP system is designed to accurately maintain the Company’s financial records, process transactions and provide timely information to its management team. While we believe that this new ERP system will enhance internal controls over financial reporting, there are inherent risks in implementing a new ERP system. Accordingly, we will continue to evaluate the design and operating effectiveness of these controls.

There have been no other changes in our internal control over financial reporting (as defined in Rule 13a-15(f) of the Exchange Act) that occurred during the quarter ended August 29, 2026, that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Attestation Report of Registered Public Accounting Firm

Our internal control over financial reporting as of August 29, 2026, has been audited by Ernst & Young, LLP, an independent registered public accounting firm, which also audited our Consolidated Financial Statements for the year ended August 29, 2026, as stated in their report included herein, which expresses an unqualified opinion on the effectiveness of our internal control over financial reporting as of August 29, 2026.
