Recently Issued Accounting Pronouncements

In December 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2023-09,Income Taxes (Topic 740). The amendments in this ASU are intended to enhance the transparency of income tax information by updating income tax disclosure requirements. The guidance is effective for public entities for annual periods beginning after December 15, 2024, and early adoption is permitted. The amendments in this ASU should be applied on a prospective basis; however, retrospective application is permitted. The Company will adopt this standard with its fiscal 2026 annual filing. The Company is currently evaluating these new disclosure requirements and does not expect the adoption to have a material impact.

In November 2024, the FASB issued ASU 2024-03,Income Statement – Reporting Comprehensive Income – Expense Disaggregation Disclosures (Subtopic 220-40).* This ASU requires disclosure in the notes to the financial statements, at each interim and annual reporting period, of specified information about certain costs and expenses including purchases of inventory, employee compensation, depreciation and intangible asset amortization included in each relevant expense caption. Also required is a qualitative description of the amounts remaining in relevant expense captions that are not separately disaggregated. This ASU is effective for all public entities for annual reporting periods beginning after December 15, 2026, and interim periods within annual reporting periods beginning after December 15, 2027, and early adoption is permitted. This ASU should be applied either prospectively to financial statements issued after the effective date of this update or retrospectively to all prior periods presented in the financial statements. The Company will adopt this standard with its fiscal 2028 annual filing. The Company is currently evaluating these new disclosure requirements and the impact of adoption. *

In September 2025, the FASB issued ASU 2025-06,*Intangibles – Goodwill and Other – Internal-Use Software (Subtopic 350-40).*This ASU is intended to modernize internal-use software guidance by removing all project stages and clarifying the thresholds entities apply to begin capitalizing costs. This ASU is effective for all entities for annual reporting periods beginning after December 15, 2027, and interim reporting periods within those annual reporting periods, and early adoption is permitted. The amendments in this ASU may be applied using a prospective, modified, or retrospective transition approach. This update will be effective for the Company beginning with its fiscal 2029 first quarter. The Company is currently evaluating the impact of adoption.

Note B – Merchandise Inventories

Merchandise inventories include related purchasing, storage and handling costs. Inventory cost has been determined using the last-in, first-out (“LIFO”) method stated at the lower of cost or market value for domestic inventories and the

weighted average cost method stated at the lower of cost or net realizable value for Mexico and Brazil inventories. The Company’s policy is not to write up inventory in excess of replacement cost. Due to price changes on the Company’s merchandise purchases, primarily due to inflation driven by tariffs, the Company’s LIFO credit reserve balance was $260.0 million at May 9, 2026, and $83.0 million at August 30, 2025. Changes to the Company’s LIFO credit reserve balance are recorded as a non-cash charge or benefit to cost of sales.

Note C – Variable Interest Entities

The Company invests in certain tax credit funds that promote renewable energy and generate a return primarily through the realization of federal tax credits. The Company considers its investments in these tax credit funds as investments in variable interest entities (“VIEs”). The Company evaluates the investment in any VIE to determine whether it is the primary beneficiary. The Company considers a variety of factors in identifying the entity that holds the power to direct matters that most significantly impact the VIE’s economic performance including, but not limited to, the ability to direct financing, leasing, construction and other operating decisions and activities. As of May 9, 2026, the Company held tax credit equity investments that were deemed to be VIEs and determined that it was not the primary beneficiary of the entities, as it did not have the power to direct the activities that most significantly impacted the entities and accounted for these investments using the equity method. The Company’s maximum exposure to losses is generally limited to its net investment, which was $71.0 million and $60.8 million as of May 9, 2026, and August 30, 2025, respectively, and was included in Other long-term assets in the Condensed Consolidated Balance Sheets.

Note D – Fair Value Measurements

The Company defines fair value as the price received to transfer an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. In accordance with ASC 820,Fair Value Measurements and Disclosures, the Company uses the fair value hierarchy, which prioritizes the inputs used to measure fair value. The hierarchy, as defined below, gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities and the lowest priority to unobservable inputs. The three levels of the fair value hierarchy are set forth below:

Level 1 inputs—unadjusted quoted prices in active markets for identical assets or liabilities that the Company can access at the measurement date.

Level 2 inputs—inputs other than quoted market prices included within Level 1 that are observable, either directly or indirectly, for the asset or liability.

Level 3 inputs—unobservable inputs for the asset or liability, which are based on the Company’s own assumptions as there is little, if any, observable activity in identical assets or liabilities.

Marketable Debt Securities Measured at Fair Value on a Recurring Basis

The Company’s marketable debt securities measured at fair value on a recurring basis were as follows:

The Company’s marketable debt securities are typically valued at the closing price in the principal active market as of the last business day of the quarter or through the use of other market inputs relating to the securities, including benchmark yields and reported trades. Fair values of the marketable debt securities, by asset class, are described in “Note E – Marketable Debt Securities.”

Additionally, the Company has deferred compensation plan assets which are recorded at fair value on a recurring basis using Level 1 inputs. These assets consisted of investments in various mutual and money markets funds of which$45.7 million is recorded in Other current assets and$32.5 million is recorded in Other long-term assets at May 9, 2026, and$2.7 million was recorded in Other current assets and$68.2 million was recorded in Other long-term assets at August 30, 2025. The Company’s liability under the plan included$45.7 million recorded in Accrued expenses and other and$32.5 million recorded in Other long-term liabilities at May 9, 2026, and$2.7 million recorded in Accrued expenses and other and$68.2 million recorded in Other long-term liabilities at August 30, 2025.

Financial Instruments not Recognized at Fair Value

The Company has financial instruments, including cash and cash equivalents, accounts receivable, other current assets and accounts payable. The carrying amounts of these financial instruments approximate fair value because of their short maturities. A discussion of the carrying values and fair values of the Company’s debt is included in “Note I – Financing.”

Note E – Marketable Debt Securities

Marketable debt securities are carried at fair value, with unrealized gains and losses, net of income taxes, recorded in Accumulated other comprehensive loss until realized, and any credit risk related losses are recognized in net income in the period incurred. The Company’s basis for determining the cost of a security sold is the “Specific Identification Model.”

The Company’s available-for-sale marketable debt securities consisted of the following:

The contractual maturities of the Company’s available for sale marketable debt securities are as follows:

At May 9, 2026, the Company held 131 securities that were in an unrealized loss position of approximately $0.5 million. In evaluating whether a credit loss exists for the securities, the Company considers factors such as the severity of the loss position, the credit worthiness of the investee, the term to maturity and the intent and ability to hold the investments until maturity or until recovery of fair value. An allowance for credit losses was deemed unnecessary given consideration of the factors above. The Company did not realize any material gains or losses on its marketable debt securities during the twelve and thirty-six week periods ended May 9, 2026, and the comparable prior year periods.

Included above in total available-for-sale marketable debt securities are $119.9 million and $117.4 million of marketable debt securities transferred by the Company’s insurance captive to a trust account to secure its obligations to an insurance company related to future workers’ compensation and casualty losses as of May 9, 2026, and August 30, 2025, respectively.

Note F – Cloud Computing Arrangements

The Company capitalizes implementation costs associated with its cloud computing arrangements when incurred, consistent with the treatment of costs capitalized for internal use software. These costs begin amortization once the related software is placed in service and will be amortized over the remaining non-cancellable term of the hosting agreement, plus any renewal periods that are reasonably certain to be exercised, and are recorded within Operating, selling, general and administrative expenses in the Company’s Condensed Consolidated Statements of Income, the same line item as the related hosting fees. Amortization expense of $0.4 million and $0.7 million was recorded in the twelve

and thirty-six weeks ended May 9, 2026, respectively, withno amortization expense recorded in the comparable prior year periods. At May 9, 2026, and August 30, 2025, capitalized cloud-based enterprise resource planning (“ERP”) software implementation costs of $2.8 million and $1.6 million, respectively, were recorded within Other current assets, and $40.5 million and $29.6 million, respectively, were recorded within Other long-term assets on the Company's Condensed Consolidated Balance Sheets. Cloud computing arrangement implementation costs are classified within operating activities in the Company’s Condensed Consolidated Statements of Cash Flows.

Note G – Supplier Financing Programs

The Company has arrangements with third-party financial institutions to confirm invoice balances owed by the Company to certain suppliers and pay the financial institutions the confirmed amounts on the invoice due dates. These arrangements allow the Company’s inventory suppliers, at their sole discretion, to enter into agreements directly with these financial institutions to finance the Company’s obligations to the suppliers at terms negotiated between the suppliers and the financial institutions. Supplier participation is optional and our obligations to our suppliers, including the amount and dates due, are not impacted by our suppliers’ decision to enter into an agreement with a third-party financial institution. As of May 9, 2026, and August 30,2025, the Company had supplier obligations outstanding that had been confirmed under these arrangements of$5.6 billion, and$5.4 billion respectively, which are included in Accounts payable and$289.4 million and$264.9 million, respectively, which are included in Other long-term liabilities in the Company’s Condensed Consolidated Balance Sheets.

Note H – Litigation

The Company is involved in various legal proceedings incidental to the conduct of its business, including, but not limited to, claims and allegations related to wage and hour violations, unlawful termination, employment practices, product liability, privacy and cybersecurity, environmental matters, intellectual property rights or regulatory compliance. The Company does not currently believe that, either individually or in the aggregate, these matters will result in liabilities material to the Company’s financial condition, results of operations or cash flows.

Note I – Financing

The Company’s debt consisted of the following:

The Company maintains a revolving credit facility (as amended from time to time, the “Revolving Credit Agreement”) with a borrowing capacity of $2.25 billion. The maximum borrowing capacity under the Revolving Credit Agreement may, at the Company’s option, subject to lenders’ approval, be increased from $2.25 billion to $3.25 billion. The Revolving Credit Agreement will terminate, and all amounts borrowed will be due and payable, on November 15, 2028. As of May 9, 2026, the Company hadno outstanding borrowings and $1.7 million of outstanding letters of credit under the Revolving Credit Agreement.

In addition to the outstanding letters of credit issued under the Revolving Credit Agreement discussed above, the Company had $166.7 million and $149.1 million in letters of credit outstanding as of May 9, 2026, and August 30, 2025, respectively. These letters of credit have various maturity dates and were issued on an uncommitted basis. Additionally, the Company’s total surety bonds commitment was $98.4 million at May 9, 2026, compared with $100.5 million at August 30, 2025. Since its fiscal year end, the Company has canceled, issued and modified stand-by letters of credit that are primarily renewed on an annual basis to cover deductible payments to its casualty insurance carriers.

As of May 9, 2026, the $1.4 billion commercial paper borrowings and the $450 million 5.050% Senior Notes due July 2026 were classified as long-term debt in the accompanying Condensed Consolidated Balance Sheets as the Company currently has the ability and intent to refinance them on a long-term basis through available capacity under its Revolving Credit Agreement. As of May 9, 2026, the Company had $2.2 billion of availability under its Revolving Credit Agreement, which would allow it to replace these short-term obligations with a long-term financing facility.

On April 21, 2026, the Company repaid its outstanding $400 million 3.125% Senior Notes due April 2026.

The Senior Notes contain a provision that repayment may be accelerated if the Company experiences both a change of control and a rating event (both as defined in the agreements). The Company’s borrowings under its Senior Notes contain minimal covenants, primarily restrictions on liens. All of the repayment obligations under its borrowing arrangements may be accelerated and come due prior to the scheduled payment date if covenants are breached or an event of default occurs. Interest for the Senior Notes is paid on a semi-annual basis.

The fair value of the Company’s debt was estimated at $9.0 billion and $8.9 billion as of May 9, 2026, and August 30, 2025, respectively, based on the quoted market prices for the same or similar issues or on the current rates available to the Company for debt of the same terms (Level 2). Such fair value is greater than the carrying value of debt by $32.7 million and $94.4 million at May 9, 2026, and August 30, 2025, respectively, which reflects the face amount, adjusted for any unamortized debt issuance costs and discounts.

As of May 9, 2026, the Company was in compliance with all covenants and expects to remain in compliance with all covenants under its borrowing arrangements.

Note J – Stock Repurchase Program

From January 1, 1998, to May 9, 2026, the Company has repurchased a total of 156.0 million shares of its common stock at an aggregate cost of $39.8 billion, including 356.3 thousand shares of its common stock at an aggregate cost of $1.3 billion during the thirty-six week period ended May 9, 2026.

On October 8, 2025, the Board voted to authorize the repurchase of an additional $1.5 billion of the Company’s common stock in connection with its ongoing share repurchase program, which raised the total value of shares authorized to be repurchased to $40.7 billion. Considering the cumulative repurchases as of May 9, 2026, the Company had $0.8 billion remaining under the Board’s authorization to repurchase its common stock.

During the thirty-six week period ended May 9, 2026, the Company retired 0.4 million shares of treasury stock which had been previously repurchased under the Company’s stock repurchase program. The retirement increased Retained deficit by $1.4 billion and decreased Additional paid-in capital by $45.1 million. During the comparable prior year period, the Company retired 0.7 million shares of treasury stock, which increased Retained deficit by $2.0 billion and decreased Additional paid-in capital by $69.9 million.

Subsequent to May 9, 2026, and through June 5, 2026, the Company has repurchased 53.9 thousand shares of its common stock at an aggregate cost of $174.0 million.

Note K – Accumulated Other Comprehensive Loss

Accumulated other comprehensive loss includes foreign currency translation adjustments, net unrealized gains (losses) on marketable debt securities, and net derivative activities.

Changes in Accumulated other comprehensive loss for the twelve week periods ended May 9, 2026, and May 10, 2025, consisted of the following:

Changes in Accumulated other comprehensive loss for the thirty-six week periods ended May 9, 2026, and May 10, 2025, consisted of the following:

Note L – Share-Based Plans

AutoZone maintains several equity incentive plans, which provide equity-based compensation to non-employee directors and eligible employees for their service to AutoZone, its subsidiaries or affiliates. The Company recognizes compensation expense for share-based payments based on the fair value of the awards at the grant date. Share-based

payments include stock option grants, restricted stock grants, restricted stock unit grants, discounts on shares sold to employees under share purchase plans and other awards. Additionally, directors’ fees are paid in restricted stock units with value equivalent to the value of shares of common stock as of the grant date. The change in fair value of liability-based stock awards is also recognized in share-based compensation expense.

Stock Options:

The Company made stock option grants for 119,235 shares during the thirty-six week period ended May 9, 2026, and granted options to purchase 122,802 shares during the comparable prior year period. The Company grants options to purchase common stock to certain of its employees under its equity incentive plans at prices equal to or above the market value of the stock on the date of grant. Option-vesting periods range from four tofive years, with the majority of options vesting ratably over four years. The fair value of each option is amortized into compensation expense on a straight-line basis over the requisite service period, less estimated forfeitures. Employees who meet the qualified retirement provisions under the AutoZone, Inc. 2020 Omnibus Incentive Award Plan are assumed to have a 0% forfeiture rate. All other employee grants assume a 10% forfeiture rate, which is based on historical experience.

The weighted average fair value of the stock option awards granted during the thirty-six week periods ended May 9, 2026, and May 10, 2025, using the Black-Scholes-Merton multiple-option pricing valuation model, was $1,265.06 and $1,026.36 per share, respectively, using the following weighted average key assumptions:

During the thirty-six week period ended May 9, 2026, and the comparable prior year period,54,837 and 117,698 stock options, respectively, were exercised at a weighted average exercise price of $1,092.99 and $906.53, respectively.

As of May 9, 2026, total unrecognized share-based expense related to stock options, net of estimated forfeitures, was approximately $165.7 million, before income taxes, which we expect to recognize over an estimated weighted average period of 2.9 years.

Restricted Stock Units:

Restricted stock unit awards are valued at the market price of a share of the Company’s stock on the date of grant. Grants of employee restricted stock units vest ratably on an annual basis over afour-year service period and are payable in shares of common stock on the vesting date. Compensation expense for grants of employee restricted stock units is recognized on a straight-line basis over thefour-year service period, less estimated forfeitures, which are consistent with stock option forfeiture assumptions. Grants of non-employee director restricted stock units are made and expensed on January 1 of each year, as they vest immediately.

The Company made grants of 2,267 and 2,743 restricted stock unit awards at weighted average grant date fair values of $3,788.99 and $3,155.36, respectively, during the thirty-six week periods ended May 9, 2026, and May 10, 2025.

During the thirty-six week period ended May 9, 2026, and the comparable prior year period,2,828 and 3,218 restricted stock unit awards, respectively, were vested at a weighted average grant date fair value of $2,694.23 and $2,041.04, respectively.

As of May 9, 2026, total unrecognized stock-based compensation expense related to nonvested restricted stock unit awards, net of estimated forfeitures, was approximately $8.6 million, before income taxes, which we expect to recognize over an estimated weighted average period of 2.7 years.

Total share-based compensation expense (a component of Operating, selling, general and administrative expenses) for the twelve and thirty-six week periods ended May 9, 2026, was $30.2 million and $97.6 million, respectively. For the comparable prior year periods, total share-based compensation expense was $29.0 million and $85.6 million, respectively.

For the twelve and thirty-six week periods ended May 9, 2026,150,738 and 117,565, respectively, stock options were excluded from the diluted earnings per share computation because they would have been anti-dilutive. For the comparable prior year periods,125,197 and 114,925 anti-dilutive stock options were excluded from the dilutive earnings per share computation.

See AutoZone’s Annual Report on Form 10-K for the year ended August 30, 2025, and other filings with the SEC for a discussion regarding the methodology used in developing AutoZone’s assumptions to determine the fair value of the option awards and a description of AutoZone’s Amended and Restated 2011 Equity Incentive Award Plan, the AutoZone, Inc. 2020 Omnibus Incentive Award Plan and the Director Compensation Program.

Note N – Commitments and Contingencies

On February 20, 2026, the U.S. Supreme Court invalidated tariffs imposed under the International Emergency Economic Powers Act (‘IEEPA’). The President immediately introduced new tariffs under different statutory authority, though their scope and duration, and the likelihood and outcome of further legal challenges to these tariffs, remain uncertain. On April 20, 2026, the Company filed for refunds of IEEPA tariffs paid directly by the Company via the U.S. Customs and Border Protection’s consolidated administration and processing of entries tool in the automated commercial environment portal. Due to the uncertainty around the timing and amount of refunds to be received, the Company has not recognized any potential IEEPA tariff refunds within its Condensed Consolidated Financial Statements as of May 9, 2026. The Company continues to monitor the potential impacts on its financial condition and results of operations.
