(“we,” “our,” “us,” “CarMax” and “the company”), including its wholly owned subsidiaries, is the nation’s largest and most profitable retailer of used vehicles. We operate in two reportable segments: CarMax Sales Operations and CarMax Auto Finance (“CAF”). Our CarMax Sales Operations segment consists of all aspects of our auto merchandising and service operations, excluding financing provided by CAF. Our CAF segment consists solely of our own finance operation that provides financing to customers buying retail vehicles from CarMax. On June 1, 2021, we completed the acquisition of Edmunds Holding Company (“Edmunds”), which does not meet the quantitative thresholds to be considered a reportable segment.</span><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:12pt;font-weight:400;line-height:112%"> </span><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:112%">See Note 17 for additional information on our reportable segments and Note 2 for additional information regarding our acquisition of Edmunds.</span></div><div><span><br/></span></div><div style="text-align:justify"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">We deliver an unrivaled customer experience by offering a broad selection of quality used vehicles and related products and services at competitive, no-haggle prices using a customer-friendly sales process. Our omni-channel platform, which gives us the largest addressable market in the used car industry, empowers our retail customers to buy a car on their terms – online, in-store or a seamless combination of both. Customers can choose to complete the car-buying experience in-person at one of our stores; or buy the car online and receive delivery through contactless curbside pickup, available nationwide, or home delivery, available to most customers. We offer customers a range of related products and services, including the appraisal and purchase of vehicles directly from consumers; the financing of retail vehicle purchases through CAF and third-party finance providers; the sale of extended protection plan (“EPP”) products, which include extended service plans (“ESPs”) and guaranteed asset protection (“GAP”); and vehicle repair service. Vehicles purchased through the appraisal process that do not meet our retail standards are sold to licensed dealers through on-site or virtual wholesale auctions.</span></div>

All significant intercompany balances and transactions have been eliminated in consolidation. These consolidated financial statements have been prepared in conformity with U.S. generally accepted accounting principles (“GAAP”) for interim financial information. Accordingly, they do not include all of the information and footnotes required by U.S. GAAP for complete financial statements. In the opinion of management, such interim consolidated financial statements reflect all normal recurring adjustments considered necessary to present fairly the financial position and the results of operations and cash flows for the interim periods presented. The results of operations for the interim periods are not necessarily indicative of the results to be expected for the full fiscal year. </span></div><div style="text-align:justify"><span><br/></span></div><div style="text-align:justify"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">The accounting policies followed in the presentation of our interim financial results are consistent with those included in the company’s Annual Report on Form 10-K for the fiscal year ended February 28, 2021 (the “2021 Annual Report”), with the exception of those related to recent accounting pronouncements adopted in the current fiscal year. These consolidated financial statements should be read in conjunction with the audited consolidated financial statements and footnotes included in our 2021 Annual Report.</span></div>
	us-gaap	Use Of Estimates UseOfEstimates	The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses and the disclosure of contingent assets and liabilities. Actual results could differ from those estimates. In particular, the novel coronavirus (“COVID-19”) pandemic continues to have an adverse impact on global economic conditions and may impact future estimates including, but not limited to, our allowance for loan losses, inventory valuations, fair value measurements, downward adjustments to investments in equity securities, asset impairment charges, the effectiveness of the company’s hedging instruments, deferred tax valuation allowances, cancellation reserves, actuarial losses on our retirement benefit plans and discount rate assumptions. Depreciation and amortization previously included in selling, general, and administrative expenses is now separately presented on the consolidated statements of earnings. Prior period amounts have been reclassified to conform to the current period’s presentation. Depreciation and amortization related to other areas of our business, including cost of sales and CAF, is included in its respective line item on the consolidated statements of earnings. Certain other prior year amounts have been reclassified to conform to the current year’s presentation. Amounts and percentages may not total due to rounding.
