NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

Note A- Basis of Presentation

The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles for interim financial information and with instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by U.S. generally accepted accounting principles for complete financial statements. In the opinion of management, all adjustments, including normal recurring accruals, considered necessary for a fair presentation have been included. Certain prior year amounts have been reclassified to conform to current year presentations. For further information, refer to the consolidated financial statements and footnotes included in the 2006 Annual Report to Shareholders for AutoZone, Inc. (“AutoZone” or the “Company”), which is incorporated by reference in its Annual Report on Form 10-K for the year ended August 26, 2006.

Operating results for the twelve and thirty-six weeks ended May 5, 2007 are not necessarily indicative of the results that may be expected for the fiscal year ending August 25, 2007. Each of the first three quarters of our fiscal year consists of 12 weeks, and the fourth quarter consists of 16 or 17 weeks. Each of the fourth quarters of fiscal 2006 and 2007 has 16 weeks. Additionally, the Company’s business is somewhat seasonal in nature, with the highest sales generally occurring in the summer months of June through August and the lowest sales generally occurring in the winter months of December through February.

Note B- Accounting for Cores

A portion of the Company’s transactions include the sale of auto parts that contain a core component. The core component represents the recyclable portion of the auto part. Customers are not charged for the core component of the new part if a used core is returned at the point of sale of the new part; otherwise the Company charges customers a specified amount for the core component representing a deposit. The Company refunds that same amount upon the customer returning a used core to the store at a later date. The used core must be from the same application part that may or may not have been purchased from the Company. Generally, less than 5% of core transactions do not involve the return of a used core. The used cores are returned to vendors to settle a current payable or to settle an obligation to return a given number of cores to vendors when the Company is not billed for the core component of the inventory acquisition cost.

The Company does not recognize sales or cost of sales for the core component of these transactions when a used part is returned or expected to be returned from the customer. The Company believes that its current accounting treatment is appropriate, but recognizes that diversity of practice exists in accounting for these transactions among aftermarket auto parts retailers and manufacturers. Recently an aftermarket auto parts retailer restated its financial results to reflect within net sales the core charge even if customers did not pay for it at point of sale or if it was subsequently refunded to customers due to the return of a used core. This restatement increased the retailer’s net sales and cost of sales by the amount of core returns. If the Company were to apply this accounting treatment, it would increase net sales and cost of sales by the amount of the core returns with no impact to gross profit dollars. In response to this recent restatement and other developments, the Company is in the process of evaluating its policy on accounting for cores and expects to complete this evaluation prior to filing its Form 10-K for its fiscal year ended August 25, 2007.

The following summarizes the amount of core charges not required to be paid by a customer at point of sale or subsequently refunded to customers due to the return of a used core that were excluded from net sales and cost of sales during the following periods:

	Core
(in millions)	Returns
Twelve Weeks Ended May 5, 2007	$	70.1
Thirty-six Weeks Ended May 5, 2007		214.5

Twelve Weeks Ended May 6, 2006		74.4
Thirty-six Weeks Ended May 6, 2006		223.3

Year Ended August 26, 2006		327.1

Note C- Share-Based Payments

Share-based compensation transactions are accounted for in accordance with the provisions of Statement of Financial Accounting Standards (“SFAS”) No. 123(R) “Share-Based Payment.” We recognize 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 and the discount on shares sold to employees under various share purchase plans.

Total share-based expense (a component of operating, selling, general and administrative expenses) was $4.2 million for the twelve week period ended May 5, 2007 and was $4.2 million for the comparable prior year period. Share-based expense was $13.0 million for the thirty-six week period ending May 5, 2007 and was $12.1 million for the comparable prior year period.

AutoZone grants options to purchase common stock to some of its employees and directors under various plans at prices equal to the fair market value of the stock on the dates the options are granted. Options have a term of 10 years or 10 years and one day from grant date. Director options generally vest three years from the grant date, but upon retirement all unvested options immediately vest. Employee options generally vest in equal annual installments on the first, second, third and fourth anniversaries of the grant date. Employees generally have 30 days after the employment relationship ends, or one year after death, to exercise all vested options. The fair value of each option grant is separately estimated for each vesting date. The fair value of each option is amortized into compensation expense on a straight-line basis between the grant date for the award and each vesting date. The Company has estimated the fair value of all stock option awards as of the date of the grant by applying the Black-Scholes-Merton multiple-option pricing valuation model. The application of this valuation model involves assumptions that are judgmental and highly sensitive in the determination of compensation expense. The weighted average key assumptions used in determining the fair value of options granted in the thirty-six week period ended May 5, 2007 are as follows:

Expected price volatility	26.0	%
Risk-free interest rate	4.6	%
Weighted average expected lives in years	3.9
Forfeiture rate	10.0	%
Dividend yield	0.0	%

The Company generally issues new shares when options are exercised. A summary of stock option activity since our most recent fiscal year end is as follows:

	Options			Weighted Average Exercise Price
Outstanding August 26, 2006		3,355,542		$	70.73
Granted		695,298			104.64
Exercised		(809,198	)		67.34
Canceled		(126,224	)		82.26
Outstanding May 5, 2007		3,115,418		$	78.71

At May 5, 2007 the total compensation cost related to non-vested awards not yet recognized was $22.9 million with a weighted average expense recognition period of 1.4 years.

On December 13, 2006, stockholders approved the AutoZone, Inc. 2006 Stock Option Plan and the AutoZone, Inc. Fourth Amended and Restated Executive Stock Purchase Plan. There have been no other modifications to the Company’s share-based compensation plans during the thirty-six week period ended May 5, 2007.

Note D- Inventories

Inventories are stated at the lower of cost or market using the last-in, first-out (“LIFO”) method. Included in inventory are related purchasing, storage, delivery and handling costs. Due to price deflation on the Company’s merchandise purchases, the Company’s inventory balances are effectively maintained under the first-in first-out method, as the Company’s policy is not to write up inventory in excess of replacement cost, resulting in cost of sales being reflected at the higher amount. The cumulative balance of this unrecorded adjustment, which would be reduced upon experiencing price inflation on our merchandise purchases, was $225.2 million at May 5, 2007, and $198.3 million at August 26, 2006.

AutoZone has entered into pay-on-scan (“POS”) arrangements with certain vendors, whereby AutoZone will not purchase merchandise supplied by a vendor until just before that merchandise is ultimately sold to AutoZone’s customers. Title and certain risks of ownership remain with the vendor until the merchandise is sold to AutoZone’s customers. Since the Company does not own merchandise under POS arrangements until just before it is sold to a customer, such merchandise is not recorded on the Company’s balance sheet. Upon the sale of the merchandise to AutoZone’s customers, AutoZone recognizes the liability for the goods and pays the vendor in accordance with the agreed-upon terms. Although AutoZone does not hold title to the goods, AutoZone controls pricing and has credit collection risk and therefore, gross revenues under POS arrangements are included in net sales in the income statement. AutoZone has financed the repurchase of existing merchandise inventory by certain vendors in order to convert such vendors to POS arrangements. These receivables, reflected in accounts receivable, have remaining durations up to 4 months and approximated $2.0 million at May 5, 2007, and $11.6 million at August 26, 2006. Merchandise under POS arrangements was $31.3 million at May 5, 2007, and $92.1 million at August 26, 2006.

Note E- Pension Plans

Prior to January 1, 2003, substantially all full-time employees were covered by a defined benefit pension plan. The benefits under the plan were based on years of service and the employee’s highest consecutive five-year average compensation. On January 1, 2003, the plan was frozen, which resulted in plan participants no longer earning new benefits under the plan formula and no new participants being able to join the pension plan.

On January 1, 2003, the Company’s supplemental defined benefit pension plan for certain highly compensated employees was also frozen, which resulted in plan participants no longer earning new benefits under the plan formula and no new participants being able to join the supplemental pension plan.

The components of net periodic benefit (income) cost related to our pension plans for all periods presented are as follows:

	Twelve Weeks Ended						Thirty-six Weeks Ended
(in thousands)	May 5, 2007			May 6, 2006			May 5, 2007			May 6, 2006

Interest cost	$	2,214		$	2,121		$	6,642		$	6,363
Expected return on plan assets		(2,387	)		(1,978	)		(7,161	)		(5,934	)
Amortization of prior service cost		(12	)		(145	)		(36	)		(435	)
Amortization of net loss		173			1,303			519			3,909
Net periodic benefit (income) cost	$	(12	)	$	1,301		$	(36	)	$	3,903

The Company makes contributions in amounts at least equal to the minimum funding requirements of the Employee Retirement Income Security Act of 1974. During the thirty-six week period ended May 5, 2007, the Company made $7.5 million in contributions to the plan and expects to fund another $0.6 million to $4.1 million during the remainder of this fiscal year.

Note F- Long-Term Debt

The Company’s long-term debt consisted of the following:

(in thousands)	May 5, 2007		August 26, 2006

Bank Term Loan due December 2009, effective interest rate of 4.55%	$	300,000	$	300,000
5.875% Senior Notes due October 2012, effective interest rate of 6.33%		300,000		300,000
5.5% Senior Notes due November 2015, effective interest rate of 4.86%		300,000		300,000
4.75% Senior Notes due November 2010, effective interest rate of 4.17%		200,000		200,000

Other		39,442		44,757
	$	1,938,942	$	1,857,157

Note G- Leases

The Company has a fleet of vehicles used for delivery to our commercial customers, travel for members of field management, and field support roles. The majority of these vehicles are leased under arrangements that have historically been accounted for as operating leases. On September 1, 2006, the Company modified its leasing arrangements with one of its leasing vendors. As a result of these modifications, many of the vehicles are now accounted for as capital leases. At May 5, 2007, the Company had capital lease assets of $29.2 million, net of accumulated depreciation of $6.7 million, and capital lease obligations of $28.6 million. The $10.7 million current portion of these obligations was recorded as a component of other current liabilities and the $17.9 million long-term portion was recorded as a component of other long-term liabilities in the condensed consolidated balance sheets.

Note H- Stock Repurchase Program

On February 26, 2007, the Board of Directors increased the Company’s cumulative share repurchase authorization limit from $4.9 billion to $5.4 billion. From January 1, 1998 to May 5, 2007, the Company has repurchased a total of 97.0 million shares at an aggregate cost of $5.144 billion; including 3,771,184 shares of its common stock at an aggregate cost of $464.5 million during the thirty-six week period ended May 5, 2007. Considering cumulative repurchases as of May 5, 2007, the Company has $255.7 million remaining under this authorization to repurchase its common stock. On June 6, 2007, the Board of Directors raised the repurchase authorization limit from $5.4 billion to $5.9 billion.

Note I- Comprehensive Income

Comprehensive income includes foreign currency translation adjustments; the impact from certain derivative financial instruments designated and effective as cash flow hedges, including changes in fair value, as applicable, and the reclassification of gains and/or losses from accumulated other comprehensive loss to net income to offset the earnings impact of the underlying items being hedged; and changes in the fair value of certain investments classified as available for sale. Comprehensive income for all periods presented is as follows:

	Twelve Weeks Ended						Thirty-six Weeks Ended
(in thousands)	May 5, 2007			May 6, 2006			May 5, 2007			May 6, 2006

Report of Independent Registered Public Accounting Firm

The Board of Directors and Stockholders

AutoZone, Inc.

We have reviewed the condensed consolidated balance sheet of AutoZone, Inc. as of May 5, 2007, the related condensed consolidated statements of income for the twelve and thirty-six week periods ended May 5, 2007 and May 6, 2006 and the condensed consolidated statements of cash flows for the thirty-six week periods ended May 5, 2007 and May 6, 2006. These financial statements are the responsibility of the Company’s management.

We conducted our review in accordance with the standards of the Public Company Accounting Oversight Board (United States). A review of interim financial information consists principally of applying analytical procedures and making inquiries of persons responsible for financial and accounting matters. It is substantially less in scope than an audit conducted in accordance with the standards of the Public Company Accounting Oversight Board, the objective of which is the expression of an opinion regarding the financial statements taken as a whole. Accordingly, we do not express such an opinion.

Based on our review, we are not aware of any material modifications that should be made to the condensed consolidated financial statements referred to above for them to be in conformity with U.S. generally accepted accounting principles.

We have previously audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheet of AutoZone, Inc. as of August 26, 2006, and the related consolidated statements of income, changes in stockholders’ equity, and cash flows for the year then ended, not presented herein, and, in our report dated October 19, 2006, we expressed an unqualified opinion on those consolidated financial statements. In our opinion, the information set forth in the accompanying condensed consolidated balance sheet as of August 26, 2006 is fairly stated, in all material respects, in relation to the consolidated balance sheet from which it has been derived.

Item 2.

Management’s Discussion and Analysis of Financial Condition and Results of Operations.

Overview

We are the leading retailer and a leading distributor of automotive replacement parts and accessories in the United States. As of May 5, 2007, we operated 3,991 stores including 110 stores in Mexico, compared with 3,791 stores including 92 stores in Mexico at May 6, 2006. Excluded from the store counts are 1 store at May 5, 2007, and 8 stores at May 6, 2006, that were closed as a result of hurricanes. Each of our stores carries an extensive product line for cars, sport utility vehicles, vans and light trucks, including new and remanufactured automotive hard parts, maintenance items, accessories and non-automotive products. Many of our stores also have a commercial sales program that provides commercial credit and prompt delivery of parts and other products to local, regional and national repair garages, dealers and service stations. We also sell the ALLDATA brand diagnostic and repair software. On the web, we sell diagnostic and repair information and auto and light truck parts through www.autozone.com. We do not derive revenue from automotive repair or installation.

Operating results for the twelve and thirty-six weeks ended May 5, 2007, are not necessarily indicative of the results that may be expected for the fiscal year ending August 25, 2007. Each of the first three quarters of our fiscal year consists of 12 weeks, and the fourth quarter consists of 16 or 17 weeks. Each of the fourth quarters of fiscal 2006 and 2007 has 16 weeks. Additionally, our business is somewhat seasonal in nature, with the highest sales generally occurring in the summer months of June through August and the lowest sales generally occurring in the winter months of December through February.

Twelve Weeks Ended May 5, 2007,

Compared with Twelve Weeks Ended May 6, 2006

Net sales for the twelve weeks ended May 5, 2007, increased $56.2 million to $1.474 billion, or 4.0% over net sales of $1.417 billion for the comparable prior year period. This increase in sales was primarily driven by sales from new stores, as domestic comparable store sales (sales for domestic stores opened at least one year) increased 0.4%. Domestic DIY sales increased 3.8%, domestic commercial sales decreased 0.4%, and combined sales from our ALLDATA and Mexico operations increased 20.2%.

Gross profit for the twelve weeks ended May 5, 2007, was $735.4 million, or 49.9% of net sales, compared with $704.0 million, or 49.7% of net sales, during the comparable prior year period. Gross profit as a percentage of sales was favorable primarily due to our ongoing category management initiatives and a focus on driving supply chain efficiencies.

Operating, selling, general and administrative expenses for the twelve weeks ended May 5, 2007, was $470.4 million, or 31.9% of net sales, compared with $450.9 million, or 31.8% of net sales, during the comparable prior year period. The increase in operating expenses, as a percentage of sales, reflected higher occupancy costs versus last year.

Interest expense, net for the twelve weeks ended May 5, 2007, was $27.1 million compared with $24.9 million during the comparable prior year period. This increase was primarily due to higher average borrowing levels, higher rates over the comparable prior year period and the recognition of interest expense on capital lease obligations. Average borrowings for the twelve weeks ended May 5, 2007, were $1.944 billion, compared with $1.904 billion for the comparable prior year period. Weighted average borrowing rates were 5.7% at May 5, 2007, and 5.4% at May 6, 2006.

Our effective income tax rate was 36.3% of pretax income for the twelve weeks ended May 5, 2007, and 36.7% for the comparable prior year period. The actual annual rate for fiscal 2007 will depend on a number of factors, including the amount and source of operating income and the timing and nature of discrete income tax events.

Net income for the twelve week period ended May 5, 2007, increased by $7.2 million to $151.6 million, and diluted earnings per share increased by 15.0% to $2.17 from $1.89 in the comparable prior year period. The impact on current quarter diluted earnings per share from the stock repurchases since the end of the comparable prior year period was an increase of $0.11.

Thirty-six Weeks Ended May 5, 2007,

Compared with Thirty-six Weeks Ended May 6, 2006

Net sales for the thirty-six weeks ended May 5, 2007, increased $157.8 million to $4.167 billion, or 3.9% over net sales of $4.009 billion for the comparable prior year period. This increase in sales was primarily driven by sales from new stores, as domestic comparable store sales (sales for domestic stores opened at least one year) increased 0.2%. Domestic DIY sales increased 3.8%, domestic commercial sales decreased 0.9%, and combined sales from our ALLDATA and Mexico operations increased 21.1%.

Gross profit for the thirty-six weeks ended May 5, 2007, was $2.060 billion, or 49.4% of net sales, compared with $1.976 billion, or 49.3% of net sales, during the comparable prior year period. Gross profit as a percentage of sales was favorable primarily due to our ongoing category management initiatives and a focus on driving supply chain efficiencies.

Operating, selling, general and administrative expenses for the thirty-six weeks ended May 5, 2007, was $1.383 million, or 33.2% of net sales, compared with $1.339 million, or 33.4% of net sales, during the comparable prior year period. The primary driver of the favorability in operating expenses over prior year were hurricane related costs incurred in last year’s first quarter, our prior year store reset efforts, and an ongoing focus to reduce expenditures throughout the organization. These efforts were partially off-set by higher occupancy costs.

Interest expense, net for the thirty-six weeks ended May 5, 2007, was $81.0 million compared with $73.0 million during the comparable prior year period. This increase was primarily due to higher average borrowing levels and higher rates over the comparable prior year period and the recognition of interest expense on capital lease obligations. Average borrowings for the thirty-six weeks ended May 5, 2007, were $1.944 billion, compared with $1.916 billion for the comparable prior year period. Weighted average borrowing rates were 5.7% at May 5, 2007, and 5.4% at May 6, 2006.

Our effective income tax rate was 36.5% of pretax income for the thirty-six weeks ended May 5, 2007, and 36.9% for the comparable prior year period. The actual annual rate for fiscal 2007 will depend on a number of factors, including the amount and source of operating income and the timing and nature of discrete income tax events.

Net income for the thirty-six week period ended May 5, 2007, increased by $22.7 million to $378.5 million, and diluted earnings per share increased by 15.5% to $5.33 from $4.62 in the comparable prior year period. The impact on current year diluted earnings per share from the stock repurchases since the end of the comparable prior year period was an increase of $0.19.

Liquidity and Capital Resources

The primary source of our liquidity is our cash flows realized through the sale of automotive parts and accessories. For the thirty-six weeks ended May 5, 2007, our net cash flows from operating activities provided $484.2 million as compared with $436.3 million during the comparable prior year period. The increase is primarily due to improvements in accounts payable. Overall cash flows from operating activities continue to benefit from our inventory purchases being largely financed by our vendors, as evidenced by an 85% accounts payable to inventory ratio.

Our net cash flows from investing activities for the thirty-six weeks ended May 5, 2007, used $167.6 million as compared with $196.5 million used in the comparable prior year period. Capital expenditures for the thirty-six weeks ended May 5, 2007, were $157.8 million compared to $182.2 million for the comparable prior year period. During this thirty-six week period, we opened 120 stores, including 10 new stores in Mexico and three stores that were previously closed as a result of hurricane damage. In the comparable prior year period, we opened 127 new stores, including 11 new stores in Mexico. We expect to invest in our business consistent with historical rates during fiscal 2007, primarily related to our new store development program and enhancements to existing stores and other infrastructure. Investing cash flows were also impacted by our wholly-owned insurance captive, which purchased $88.8 million in marketable securities and sold $76.9 million in short-term investments during the thirty-six week period ended May 5, 2007. During the comparable prior year period, this captive purchased $138.2 million in marketable securities and sold $121.4 million in short-term investments.

Our net cash flows from financing activities for the thirty-six weeks ended May 5, 2007, used $325.5 million compared to $230.6 million provided in the comparable prior year period. Net proceeds from commercial paper borrowings were $87.1 million versus $115.3 million in the comparable prior year period. Stock repurchases were $464.5 million in the current period as compared with $238.1 million in the comparable prior year period. For the thirty-six weeks ended May 5, 2007, proceeds from the sale of common stock and exercises of stock options provided $66.1 million, including $14.5 million in related tax benefits. In the comparable prior year period, proceeds from the sale of common stock and exercises of stock options provided $44.6 million, including $9.4 million in related tax benefits.

Depending on the timing and magnitude of our future investments (either in the form of leased or purchased properties or acquisitions), we anticipate that we will rely primarily on internally generated funds and available borrowing capacity to support a majority of our capital expenditures, working capital requirements and stock repurchases. The balance may be funded through new borrowings. We anticipate that we will be able to obtain such financing in view of our credit rating and favorable experiences in the debt market in the past.

Credit Ratings

At May 5, 2007, AutoZone had a senior unsecured debt credit rating from Standard & Poor’s of BBB+ and a commercial paper rating of A-2. Moody’s Investors Service had assigned us a senior unsecured debt credit rating of Baa2 and a commercial paper rating of P-2. As of May 5, 2007, Moody’s and Standard & Poor’s had AutoZone listed as having a “stable” outlook. If our credit ratings drop, our interest expense may increase; similarly, we anticipate that our interest expense may decrease if our investment ratings are raised. If our commercial paper ratings drop below current levels, we may have difficulty continuing to utilize the commercial paper market and our interest expense could increase, as we could then be required to access more expensive bank lines of credit. If our senior unsecured debt ratings drop below investment grade, our access to financing may become more limited.

Debt Facilities

We maintain $1.0 billion of revolving credit facilities with a group of banks to primarily support commercial paper borrowings, letters of credit and other short-term unsecured bank loans. These facilities expire in May 2010, may be increased to $1.3 billion at AutoZone’s election, allow up to $200 million in letters of credit, and allow up to $100 million in capital leases. As the available balance is reduced by commercial paper borrowings and certain outstanding letters of credit, the Company had $672.3 million in available capacity under these facilities at May 5, 2007. The rate of interest payable under the credit facilities is a function of Bank of America’s base rate or a Eurodollar rate (each as defined in the facility agreements), or a combination thereof.

Our borrowings under our Senior Notes arrangements contain minimal covenants, primarily restrictions on liens. Under our other borrowing arrangements, covenants include limitations on total indebtedness, restrictions on liens, a minimum fixed charge coverage ratio and a provision where repayment obligations may be accelerated if AutoZone experiences a change in control (as defined in the agreements) of AutoZone or its Board of Directors. All of the repayment obligations under our borrowing arrangements may be accelerated and come due prior to the scheduled payment date if covenants are breached or an event of default occurs. As of May 5, 2007, we were in compliance with all covenants and expect to remain in compliance with all covenants.

Stock Repurchases

On February 26, 2007, the Board of Directors increased the Company’s cumulative share repurchase authorization limit from $4.9 billion to $5.4 billion. From January 1, 1998 to May 5, 2007 the Company has repurchased a total of 97.0 million shares at an aggregate cost of $5.144 billion; including 3,771,184 shares of its common stock at an aggregate cost of $464.5 million during the thirty-six week period ended May 5, 2007. Considering cumulative repurchases as of May 5, 2007, the Company has $255.7 million remaining under this authorization to repurchase its common stock. On June 6, 2007, the Board of Directors raised the repurchase authorization limit from $5.4 billion to $5.9 billion.

Off-Balance Sheet Arrangements

In conjunction with our commercial sales program, we offer credit to some of our commercial customers. Certain of the receivables related to the credit program are sold to a third party at a discount for cash with limited recourse. We have established a reserve for this recourse. At May 5, 2007, the receivables facility had an outstanding balance of $58.8 million and the balance of the recourse reserve was approximately $1.9 million.

Since fiscal year end, we have cancelled, issued new and modified existing stand-by letters of credit that are primarily renewed on an annual basis to cover premium and deductible payments to our workers’ compensation carrier. Our total standby letters of credit commitment at May 5, 2007 was $118.4 million compared with $131.6 million at August 26, 2006, and our total surety bonds commitment at May 5, 2007, was $11.7 million compared with $12.8 million at August 26, 2006.

We have entered into pay-on-scan (“POS”) arrangements with certain vendors, whereby we will not purchase merchandise supplied by a vendor until just before that merchandise is ultimately sold to our customers. Title and certain risks of ownership remain with the vendor until the merchandise is sold to our customers. Since we do not own merchandise under POS arrangements until just before it is sold to a customer, such merchandise is not recorded on our balance sheet. Upon the sale of the merchandise to our customers, we recognize the liability for the goods and pay the vendor in accordance with the agreed-upon terms. Although we do not hold title to the goods, we control pricing and credit collection risk and therefore, gross revenues under POS arrangements are included in net sales in the income statement. Sales of merchandise under POS approximated $31.5 million and $141.7 million for the twelve and thirty-six weeks ended May 5, 2007, and $86.0 million and $303.4 million for the twelve and thirty-six weeks ended May 6, 2006. Merchandise under POS arrangements was $31.3 million at May 5, 2007, and $92.1 million at August 26, 2006.

Critical Accounting Policies

As there have been no changes to our critical accounting policies during fiscal 2007, refer to our Annual Report to Shareholders, which is incorporated by reference in our Annual Report on Form 10-K for the fiscal year ended August 26, 2006, for a summary of our policies.

Forward-Looking Statements

Certain statements contained in this Quarterly Report on Form 10-Q are forward-looking statements. Forward-looking statements typically use words such as “believe,” “anticipate,” “should,” “intend,” “plan,” “will,” “expect,” “estimate,” “project,” “positioned,” “strategy” and similar expressions. These are based on assumptions and assessments made by our management in light of experience and perception of historical trends, current conditions, expected future developments and other factors that we believe to be appropriate. These forward-looking statements are subject to a number of risks and uncertainties, including without limitation, competition; product demand; the economy; the ability to hire and retain qualified employees; consumer debt levels; inflation; weather; raw material costs of our suppliers; energy prices; war and the prospect of war, including terrorist activity; availability of commercial transportation; construction delays; access to available and feasible financing; and changes in laws or regulations. Forward-looking statements are not guarantees of future performance and actual results, developments and business decisions may differ from those contemplated by such forward-looking statements, and such events could materially and adversely affect our business. Forward-looking statements speak only as of the date made. Except as required by applicable law, we undertake no obligation to update publicly any forward-looking statements, whether as a result of new information, future events or otherwise. Actual results may materially differ from anticipated results. Please refer to the Risk Factors section contained in our Annual Report on Form 10-K for the fiscal year ended August 26, 2006, for more information related to those risks.

Item 3.

Quantitative and Qualitative Disclosures About Market Risk.

At May 5, 2007, the only material changes to our instruments and positions that are sensitive to market risk since the disclosures in our 2006 Annual Report to Shareholders, which is incorporated by reference in our Annual Report on Form

10-K, was the $87.1 million net increase in commercial paper, the purchase of $88.8 million in marketable securities, partially off-set by the sale of $76.9 million in short-term investments, to support the self-insurance reserves in our wholly-owned insurance captive, and the execution of two forward-starting fuel swaps for a portion of our diesel fuel and unleaded fuel exposure. Mark-to-market gains of $0.5 million are recorded in operating, selling, general and administrative expenses and the portion related to diesel usage is then reclassed based on gallons used to cost of sales as a component of distribution costs.

The fair value of our debt was estimated at $1.941 billion as of May 5, 2007, and $1.825 billion as of August 26, 2006, based on the quoted market prices for the same or similar debt issues or on the current rates available to AutoZone for debt of the same remaining maturities. Such fair value is greater than the carrying value of debt by $2.0 million at May 5, 2007, and less than the carrying value of debt by $32.3 million at August 26, 2006. Considering the effect of any interest rate swaps designated and effective as cash flow hedges, we had $248.9 million of variable rate debt outstanding at May 5, 2007, and $167.2 million of variable rate debt outstanding at August 26, 2006. At these borrowing levels for variable rate debt, a one percentage point increase in interest rates would have had an unfavorable annual impact on our pre-tax earnings and cash flows of $2.5 million in fiscal 2007 and $1.7 million in fiscal 2006, which includes the effects of interest rate swaps. The primary interest rate exposure on variable rate debt is based on LIBOR. Considering the effect of any interest rate swaps designated and effective as cash flow hedges, we had outstanding fixed rate debt of $1.690 billion at May 5, 2007, and August 26, 2006. A one percentage point increase in interest rates would reduce the fair value of our fixed rate debt by $63.6 million at May 5, 2007 and $68.3 million at August 26, 2006.

Item 4.

Controls and Procedures.

An evaluation was performed under the supervision and with the participation of our management, including the Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and operation of our disclosure controls and procedures as of May 5, 2007. Based on that evaluation, our management, including the Chief Executive Officer and Chief Financial Officer, concluded that our disclosure controls and procedures were effective as of May 5, 2007. During or subsequent to the quarter ended May 5, 2007 there were no changes in our internal controls that have materially affected or are reasonably likely to materially affect, internal controls over financial reporting.

PART II. OTHER INFORMATION

Item 1.

Legal Proceedings.

As of the date of this filing, there have been no additional material legal proceedings or material developments in the legal proceedings disclosed in our 2006 Annual Report to Shareholders for AutoZone, Inc., which is incorporated by reference in our Annual Report on Form 10-K for the year ended August 26, 2006.

March 11, 2007 to April 7, 2007	1,269,919	128.12	96,555,193	312,837,894
April 8, 2007 to May 5, 2007	438,100	130.41	96,993,293	255,704,345
Total	1,907,819	$ 128.32	96,993,293	$ 255,704,345

All of the above repurchases were part of publicly announced plans that were authorized by the Company’s Board of Directors for the purchase of a maximum of $5.4 billion in common shares as of May 5, 2007.

March 19, 2007

Mr. Larry Roesel

3143 White Eagle Drive

Naperville, IL 60564

Dear Larry:

On behalf of AutoZone, I am delighted to offer to you the position of Senior Vice President, Commercial, subject to Board approval (anticipated to be March 21, 2007), reporting directly to me. This position is a member of the Executive Committee.

Our offer includes a base salary of $350,000 per annum plus an annual bonus target of 60% of your base salary. You will be eligible for a performance and salary review at the end of Fiscal 2007. We will guarantee your Fiscal 2007 Bonus at a minimum 100% payout, prorated for your time in position for Fiscal 2007. Actual bonus awards for Fiscal 2007 will be determined by the achievement of pre-defined Company and Business Unit objectives. Bonus can therefore be less than target, but can also exceed targets based on above-plan performance.

AutoZone will provide a gross sign-on bonus of $25,000, payable 1/2 up front and 1/2 after one year of service. Tax withholding and other reasonable and customary deductions will be deducted from the $25,000 gross payment.

Subject to the approval of the Compensation Committee of the Board of Directors of AutoZone, Inc., you will receive an initial AutoZone, Inc. common stock option grant of 20,000 non-qualified stock options, which will be granted in accordance with the AutoZone, Inc. 2006 Stock Option Plan. These options will be presented to the Compensation Committee for consideration at or before the next meeting of the Compensation Committee which occurs after your start date. Thereafter, on an annual basis, beginning on or around October 2007, subsequent grants will be determined by pre-defined performance achievements and the established annual range of options. All stock option grants are made by the Compensation Committee of the Board of Directors of AutoZone. Notwithstanding, any and all Stock Option Plans and future grants are subject to change or may be discontinued at any time.

Our offer of employment also includes relocation support, outlined in the Relocation Policy you will receive. This includes coverage for the home sale and purchase transaction costs, personal goods shipment, and suitable temporary housing. The cap for eligibility for the home sale program will be a home sale value not to exceed $750,000. We will also include a one-time miscellaneous gross payment of $10,000, as noted in the relocation policy (minus tax withholding and other customary deductions).

You will be eligible to participate in AutoZone's full group benefit programs, which currently include medical, dental, vision, life and 401(k) program (subject to the terms and conditions of each program). There is also a company paid Executive Disability Plan to include short-term and long-term disability.

As a Senior Vice President, you are eligible to participate in our Executive Medical Health Plan and the Executive Stock Purchase Plan. You are also eligible for four weeks of vacation. These benefits are granted and reviewed on an annual basis. All benefits are subject to review and may change from time to time.

Notwithstanding, your employment will be “at will” and terminable at any time.

Larry, the entire Executive Committee and the Board are enthusiastic about you joining our team. I am personally looking forward to your positive response and to working with you for many years to come. Please feel free to call me or Tim Briggs if you have any questions.

Sincerely,

/s/ Bob

Bob Olsen
