Description of Business and Summary of Significant Accounting Policies	NOTE 1. Description of Business and Summary of Significant Accounting Policies Description of Business. Cars.com Inc., d/b/a Cars Commerce Inc. (the "Company" or "Cars Commerce") is an audience-driven technology company empowering the automotive industry. The Company simplifies everything about car buying and selling with powerful products powered by data and machine learning that span pretail, retail and post-sale activities – enabling more efficient and profitable retail operations. The Cars Commerce platform is organized around five industry-leading capabilities: the flagship automotive marketplace and dealer reputation site Cars.com, award-winning website and digital retail technology and marketing services from Dealer Inspire and D2C Media, essential trade-in and appraisal technology from AccuTrade, a reputation-based dealer-to-dealer wholesale auction from DealerClub and exclusive in-market media solutions from the Cars Commerce Media Network. Basis of Presentation. The accompanying unaudited interim consolidated financial statements ("Consolidated Financial Statements") have been prepared in conformity with accounting principles generally accepted in the United States of America ("U.S. GAAP") and the rules and regulations of the Securities and Exchange Commission (the "SEC") for interim financial statements. Accordingly, certain information and footnote disclosures normally included in financial statements prepared in accordance with U.S. GAAP have been condensed or omitted pursuant to the SEC rules and regulations. These Consolidated Financial Statements should be read in conjunction with the audited consolidated financial statements and the notes thereto for the year ended December 31, 2024, which are included in the Company's Annual Report on Form 10-K as filed with the SEC on February 27, 2025 (the "December 31, 2024 Consolidated Financial Statements"). The significant accounting policies used in preparing these Consolidated Financial Statements were applied on a basis consistent with those reflected in the December 31, 2024 Consolidated Financial Statements. In the opinion of management, the Consolidated Financial Statements contain all adjustments (consisting of a normal, recurring nature) necessary to present fairly the Company's financial position, results of operations, cash flows and changes in stockholders' equity as of the dates and for the periods indicated. The unaudited results of operations for the three and nine months ended September 30, 2025 are not necessarily indicative of results that may be expected for the year ending December 31, 2025. Use of Estimates. The preparation of the accompanying Consolidated Financial Statements in accordance with U.S. GAAP requires management to make estimates and assumptions that affect amounts reported in the Consolidated Financial Statements and accompanying disclosures. Although these estimates are based on management’s best knowledge of current events and actions that the Company may undertake in the future, actual results may differ from those estimates. Reclassifications. Certain prior year balances have been reclassified to conform to the current year presentation. These reclassifications were not material to the previously reported Consolidated Financial Statements. Principles of Consolidation. The accompanying Consolidated Financial Statements include the accounts of Cars Commerce and its 100% owned subsidiaries, including DealerClub since the date of acquisition. All intercompany transactions and accounts have been eliminated in consolidation. Recently Issued Accounting Standards Not Yet Adopted. In September 2025, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2025-06, Intangibles - Goodwill and Other-Internal-Use Software (Subtopic 350-40): Targeted Improvements to the Accounting for Internal-Use Software, which modernizes the accounting for internal-use software costs by eliminating the stage-based model in current U.S. GAAP and clarifying when capitalization of software development costs are appropriate. The standard removes the concept of discrete development stages and introduces a principle-based framework centered on whether management has authorized and committed to funding the project, and whether it is probable that the project will be completed and the software will be used to perform its intended function. This amendment is effective for annual reporting periods beginning after December 15, 2027, and for interim reporting periods beginning after December 15, 2027. Early adoption is permitted and entities are permitted to apply the new guidance in a prospective, modified or retrospective approach. The Company is currently evaluating this new guidance and its impact on its Consolidated Financial Statements and related disclosures. In November 2024, the FASB issued ASU 2024-03, Income Statement Reporting Comprehensive Income Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses, which requires companies to provide more detailed and organized disclosures of their expenses in their income statements. The standard requires breaking down expenses into specific categories, such as employee compensation and costs related to depreciation and amortization. This amendment is effective for annual reporting periods beginning after December 15, 2026, and interim reporting periods beginning after December 15, 2027, on a prospective basis and early adoption and retrospective application is permitted. The Company is currently evaluating this new guidance and its impact on its financial statement disclosures. In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures, which requires presentation of specific categories of reconciling items, as well as reconciling items that meet a quantitative threshold, in the reconciliation between the income tax provision and the income tax provision using statutory tax rates. The standard also requires disclosure of income taxes paid disaggregated by jurisdiction with separate disclosure of income taxes paid to individual jurisdictions that meet a quantitative threshold. This amendment is effective for fiscal years beginning after December 15, 2024, on a prospective basis and early adoption and retrospective application are permitted. The Company will adopt the relevant presentation requirements in its financial statement disclosures contained in its Annual Report on Form 10-K for the year ending December 31, 2025.
