(“we,” “our,” “us,” “CarMax” and “the company”), including its wholly owned subsidiaries, is the nation’s largest 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. </span></div><div style="margin-bottom:12pt;text-align:justify"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">On June 1, 2021, we completed the acquisition of Edmunds Holding Company (“Edmunds”). At that time, Edmunds was identified as a non-reportable operating segment and has been presented as “Other” in the Segment Information footnote in our prior period financial statements. Since the acquisition, Edmunds’ business strategy has become increasingly integrated with that of CarMax Sales Operations. Beginning in the first quarter of fiscal 2025, the chief operating decision maker (“CODM”) assessed the financial performance related to Edmunds’ operations together with the rest of the CarMax Sales Operations segment. As a result, as of May 31, 2024, the company realigned its operating segments to be consistent with the manner in which the CODM assesses performance and makes resource allocations. The company now operates in two operating segments, CarMax Sales Operations and CAF, both of which continue to be reportable segments.</span></div><div style="margin-bottom:12pt;text-align:justify"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">The operating segment change did not impact the company’s consolidated financial statements but did impact our previous segment footnote disclosure. The Segment Information footnote is no longer presented, as the previous disclosures were for the purpose of presenting the Edmunds operating segment separate from CarMax Sales Operations. The current and prior period required disclosures related to our reportable segments are included elsewhere within the consolidated financial statements and related footnotes. The performance of our CarMax Sales Operations segment is reviewed by our CODM at the gross profit level, the components of which are presented within the consolidated statement of earnings. The required segment information related to our CAF segment is presented in Note 3. Additionally, asset information by segment is not utilized for purposes of assessing performance or allocating resources and, as a result, such information has not been presented.</span></div><div style="margin-bottom:12pt;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 an integrated combination of both. 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”); advertising and subscription services; 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>
