Interim Financial Statements INTERIM FINANCIAL STATEMENTS
Business and Basis of Presentation
AutoNation, Inc., through its subsidiaries, is one of the largest automotive retailers in the United States. As of June 30, 2025, we owned and operated 322 new vehicle franchises from 244 stores located in the United States, predominantly in major metropolitan markets in the Sunbelt region. Our stores sell 30 different new vehicle brands. The core brands of new vehicles that we sell, representing approximately 88% of the new vehicles that we sold during the six months ended June 30, 2025, are manufactured by Toyota (including Lexus), Honda, Ford, General Motors, BMW, Mercedes-Benz, Stellantis, and Volkswagen (including Audi and Porsche). As of June 30, 2025, we also owned and operated 52 AutoNation-branded collision centers, 26 AutoNation USA used vehicle stores, 4 AutoNation-branded automotive auction operations, 3 parts distribution centers, a mobile automotive repair and maintenance business, and an auto finance company.
We offer a diversified range of automotive products and services, including new vehicles, used vehicles, “parts and service” (also referred to as “After-Sales”), which includes automotive repair and maintenance services as well as wholesale parts and collision businesses, and automotive “finance and insurance” products (also referred to as “Customer Financial Services”), which include vehicle service and other protection products, as well as the arranging of financing for vehicle purchases through third-party finance sources. We also offer indirect financing through our captive finance company on vehicles we sell. For convenience, the terms “AutoNation,” “Company,” and “we” are used to refer collectively to AutoNation, Inc. and its subsidiaries, unless otherwise required by the context. Our store and other operations are conducted by our subsidiaries.
The accompanying Unaudited Condensed Consolidated Financial Statements include the accounts of AutoNation, Inc. and its subsidiaries; intercompany accounts and transactions have been eliminated. The accompanying Unaudited Condensed Consolidated Financial Statements have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) for interim financial information and in accordance with the rules and regulations of the Securities and Exchange Commission (“SEC”). Accordingly, they do not include all of the information and notes required by GAAP for complete financial statements. Additionally, operating results for interim periods are not necessarily indicative of the results that can be expected for a full year. The Unaudited Condensed Consolidated Financial Statements herein should be read in conjunction with our audited Consolidated Financial Statements and notes thereto included within our most recent Annual Report on Form 10-K. These Unaudited Condensed Consolidated Financial Statements reflect, in the opinion of management, all material adjustments (which include only normal recurring adjustments) necessary to fairly state, in all material respects, our financial position and results of operations for the periods presented.
The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. In preparing these financial statements, management has made its best estimates and judgments of certain amounts included in the financial statements. We base our estimates and judgments on historical experience and other assumptions that we believe are reasonable. However, application of these accounting policies involves the exercise of judgment and use of assumptions as to future uncertainties and, as a result, actual results could differ materially from these estimates. We periodically evaluate estimates and assumptions used in the preparation of the financial statements and make changes on a prospective basis when adjustments are necessary. Such estimates and assumptions affect, among other things, our goodwill, indefinite-lived intangible asset, and long-lived asset valuations; inventory valuation; equity investment valuation; assets held for sale; assessments of variable consideration and related constraints associated with retrospective commissions; accruals for chargebacks against revenue recognized from the sale of finance and insurance products; accruals related to self-insurance programs; certain legal proceedings; assessment of the annual income tax expense; valuation of deferred income taxes and income tax contingencies; the allowance for expected credit losses; and measurement of performance-based compensation costs.
Certain reclassifications of amounts previously reported have been made to the accompanying Unaudited Condensed Consolidated Financial Statements in order to maintain consistency and comparability between periods presented.
Recent Accounting Pronouncements
In December 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standard Update (“ASU”) 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures, that 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. The amendments in this accounting standard are effective for annual periods beginning after December 15, 2024, on a prospective basis. Early adoption and retrospective application are permitted. We do not expect the adoption of this accounting standard to have an impact on our consolidated financial statements, but will require certain additional 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, that requires disclosure of the amounts of purchases of inventory, employee compensation, depreciation, and intangible asset amortization included in each relevant expense line item on the income statement. The standard also requires a qualitative description of other amounts included in each relevant expense line item on the income statement that are not separately disclosed. In addition, entities are required to disclose the nature and amount of selling expenses. The new standard is effective for annual reporting periods beginning after December 15, 2026, and interim reporting periods beginning after December 15, 2027. Early adoption is permitted. We do not expect the adoption of this accounting standard to have an impact on our consolidated financial statements, but will require certain additional disclosures.

Revenue Recognition REVENUE RECOGNITION
Disaggregation of Revenue
The significant majority of our revenue is from contracts with customers. Taxes assessed by governmental authorities that are directly imposed on revenue transactions are excluded from revenue and expenses. In the following tables, revenue is disaggregated by major lines of goods and services and timing of transfer of goods and services. The tables also include a reconciliation of the disaggregated revenue to reportable segment revenue.

Transaction Price Allocated to Remaining Performance Obligations
We sell a vehicle maintenance program (the AutoNation Vehicle Care Program or “VCP”) under which a customer purchases a specific number of maintenance services to be redeemed at an AutoNation location over a five-year term from the date of purchase. We satisfy our performance obligations related to this program and recognize revenue as the maintenance services are rendered, since the customer benefits when we have completed the maintenance service.
The following table includes estimated revenue expected to be recognized in the future related to VCP performance obligations that are unsatisfied (or partially unsatisfied) at the end of the reporting period:

As a practical expedient, since all other automotive repair and maintenance services are generally performed within one year or less, we do not disclose estimated revenue expected to be recognized in the future for all other automotive repair and maintenance performance obligations that are unsatisfied (or partially unsatisfied) at the end of the reporting period or when we expect to recognize such revenue.
Contract Assets and Liabilities
When the timing of our provision of goods or services is different from the timing of payments made by our customers, we recognize either a contract asset (performance precedes contractual due date) or a contract liability (customer payment precedes performance). Contract assets primarily relate to our right to consideration for work in process not yet billed at the reporting date associated with automotive repair and maintenance services, as well as our estimate of variable consideration that has been included in the transaction price for certain finance and insurance products (retrospective commissions). These contract assets are reclassified to receivables when the right to consideration becomes unconditional. Contract liabilities primarily relate to upfront payments received from customers for the sale of VCP contracts.
Our receivables from contracts with customers are included in Receivables, net, our current contract asset is included in Other Current Assets, our long-term contract asset is included in Other Assets, our current contract liability is included in Other
Current Liabilities, and our long-term contract liability is included in Other Liabilities in our Unaudited Condensed Consolidated Balance Sheets.

AutoNation Finance Income (Loss) [Abstract]  
AutoNation Finance Income (Loss) AUTONATION FINANCE INCOME (LOSS)
AutoNation Finance (“ANF”), our captive auto finance company, provides indirect financing to qualified retail customers on vehicles we sell. ANF income (loss) includes the interest and fee income generated by auto loans receivable less the interest expense associated with the debt issued or used to fund these receivables, a provision for estimated credit losses on the auto loans receivable originated or acquired, and direct expenses. Interest income on auto loans receivable is recognized over the contractual term of the related loans. ANF income (loss) does not include amortization of intercompany discounts or intercompany dealer participation fees. Direct costs associated with loan originations are capitalized and amortized using the effective interest method. The following table presents the components of AutoNation Finance income (loss):

In June 2024, our business was impacted by an outage of our dealer management system provided by CDK Global, which is used to support our dealership operations, including our sales, service, inventory, customer relationship management, and accounting functions. As a result, our results of operations and earnings per share for the three and six months ended June 30, 2024, were negatively impacted by lost income from the disruption to our operations and one-time compensation costs paid to commission-based associates to ensure business continuity.

Auto loans receivable primarily consist of amounts due from customers related to retail vehicle sales financed through AutoNation Finance, our captive auto finance company. Auto loans receivable are presented net of an allowance for expected credit losses. Auto loans receivable represent a large group of smaller-balance homogeneous loans, which we consider to be part of one class of financing receivable and one portfolio segment for purposes of determining our allowance for expected credit losses.

Credit Quality
We utilize proprietary credit scoring models to rate the risk of default for customers that apply for financing by evaluating customer credit history and certain credit application information, including information such as income, collateral, and down payment. The scoring models yield credit program tiers that reflect our internal credit risk ratings and represent the relative likelihood of repayment. The assigned credit tier influences the terms of the agreement, such as the required loan-to-value ratio and interest rate. After origination, credit tier assignments by customer are generally not updated. We monitor the credit quality of the auto loans receivable on an ongoing basis and also validate the accuracy of the credit scoring models periodically. Loan performance is reviewed on a recurring basis to identify whether the assigned credit tiers adequately reflect the customers’ likelihood of repayment, and if needed, adjustments are made to the scoring models on a prospective basis.
Auto Loans Receivable by Major Credit Program
The following tables present auto loans receivable as of June 30, 2025, and December 31, 2024, disaggregated by major credit program tier, in descending order of highest likelihood of repayment:

Allowance for Credit Losses
The allowance for credit losses represents the net credit losses expected over the remaining contractual life of our auto loans receivable. The allowance for credit losses is determined using a vintage-level statistical model that captures the relationship between historical changes in gross losses and the lifetime loss curves by month on book, credit tiers at origination, and seasonality, adjusted for expected recoveries based on historical recovery trends. The credit loss model also incorporates reasonable and supportable forecasts about the future utilizing a forecast of a macroeconomic variable, specifically, the change in U.S. disposable personal income, which we believe is most strongly correlated to evaluating and predicting expected credit losses of our auto loans receivable. We utilize a reasonable and supportable forecast period of one year, after which we immediately revert to historical experience.
We periodically consider whether the use of alternative variables would result in improved credit loss model accuracy and revise the model when appropriate. We also consider whether qualitative adjustments are necessary for factors that are not reflected in the quantitative methods but impact the measurement of estimated credit losses. Such adjustments include the expectations of the impact of recent economic trends on customer behavior.
The net loss estimate is calculated by applying the loss rates developed using the methods described above to the amortized cost basis of the auto loans receivable. The change in the allowance for credit losses is recognized through an adjustment to the provision for credit losses.
Rollforward of Allowance for Credit Losses
The following is a rollforward of our allowance for expected credit losses for auto loans receivable for the six months ended June 30, 2025:

We also estimate expected credit losses related to unfunded loan commitments and record a liability within Other Current Liabilities in our Unaudited Condensed Consolidated Balance Sheet. The change in the liability is recognized through an adjustment to the provision for credit losses. The credit loss liability totaled $1.5 million at June 30, 2025 and $2.8 million at December 31, 2024.
Past Due Auto Loans Receivable
An account is considered delinquent if 95% of the required principal and interest payments have not been received as of the date such payments were due. All loans continue to accrue interest until repayment, write-off, or when a loan reaches 75 days past due. If payment is received after a loan has stopped accruing interest due to reaching 75 days past due, the loan will be deemed current and the accrual of interest resumes. When a write-off occurs, accrued interest is written off by reversing interest income. Payments received on nonaccrual assets are recorded using a combination of the cost recovery method and the cash basis method depending on whether the related loan has been written off. In general, accounts are written off on the last business day of the month during which the earliest of the following occurs: the receivable is 120 days or more delinquent as of the last business day of the month and the related vehicle has not been repossessed, the vehicle has been repossessed and liquidated, or the related vehicle has been in repossession inventory for at least 60 days.

Vehicle floorplan payable-trade reflects amounts borrowed to finance the purchase of specific new and, to a lesser extent, used vehicle inventories with the corresponding manufacturers’ captive finance subsidiaries (“trade lenders”). Vehicle floorplan payable-non-trade represents amounts borrowed to finance the purchase of specific new and, to a lesser extent, used vehicle inventories with non-trade lenders, as well as amounts borrowed under our secured used vehicle floorplan facilities. Our service loaner inventory, which is reflected in Other Assets, is also financed with vehicle floorplan payable-trade and non-trade. Changes in vehicle floorplan payable-trade are reported as operating cash flows and changes in vehicle floorplan payable-non-trade are reported as financing cash flows in the accompanying Unaudited Condensed Consolidated Statements of Cash Flows.
Our inventory costs are generally reduced by manufacturer holdbacks, incentives, floorplan assistance, and non-reimbursement-based manufacturer advertising rebates, while the related vehicle floorplan payables are reflective of the gross cost of the vehicle. The vehicle floorplan payables, as shown in the above table, may also be higher than the inventory cost due to the timing of the sale of a vehicle and payment of the related liability.
Vehicle floorplan facilities are due on demand, but in the case of new vehicle inventories, are generally paid within several business days after the related vehicles are sold. Vehicle floorplan facilities are primarily collateralized by vehicle inventories and related receivables.
At June 30, 2025, our new vehicle floorplan facilities utilized Prime-based and SOFR-based interest rates. Our new vehicle floorplan outstanding had a weighted-average interest rate of 6.0% at June 30, 2025, and 6.1% at December 31, 2024. As of June 30, 2025, the aggregate capacity under our new vehicle floorplan facilities to finance our new vehicle inventory was approximately $4.7 billion, of which $3.1 billion had been borrowed based on the eligible new vehicle inventory that was pledged as collateral.
At June 30, 2025, our used vehicle floorplan facilities utilized Prime-based and SOFR-based interest rates. Our used vehicle floorplan outstanding had a weighted-average interest rate of 5.8% at June 30, 2025, and 5.8% at December 31, 2024. As of June 30, 2025, the aggregate capacity under our used vehicle floorplan facilities to finance a portion of our used vehicle inventory was $809.8 million, of which $603.3 million had been borrowed. The remaining borrowing capacity of $206.5 million was limited to $0.2 million based on the eligible used vehicle inventory that was pledged as collateral.

Goodwill
Goodwill for our reporting units is tested for impairment annually as of April 30 or more frequently when events or changes in circumstances indicate that impairment may exist.
Under accounting standards, we chose to make a qualitative evaluation about the likelihood of goodwill impairment for
our annual impairment testing as of April 30, 2025, for our Domestic, Import, Premium Luxury, AutoNation Finance, and Collision Center reporting units and determined that it was not more likely than not that the fair values of these reporting units were less than their carrying amounts. For our Mobile Service reporting unit, which relates to the mobile automotive repair and maintenance start-up business we acquired in the first quarter of 2023, we elected to perform a quantitative goodwill impairment test as of April 30, 2025, and determined that its fair value was less than its carrying value. As a result, during the three months ended June 30, 2025, we recorded a non-cash goodwill impairment charge of $65.3 million. The non-cash impairment charge is reflected as Goodwill Impairment in the accompanying Unaudited Condensed Consolidated Statements of Income. See Note 14 of the Notes to Unaudited Condensed Consolidated Financial Statements for information about our annual goodwill impairment test.

On February 24, 2025, we issued $500.0 million aggregate principal amount of 5.89% Senior Notes due 2035, which were sold at 99.995% of the aggregate principal amount.
The interest rates payable on our 4.5% Senior Notes, 3.8% Senior Notes, and 4.75% Senior Notes are subject to adjustment upon the occurrence of certain credit rating events as provided in the indentures for these senior unsecured notes.
Under our amended and restated credit agreement, we have a $1.9 billion revolving credit facility that matures on July 18, 2028. The credit agreement also contains an accordion feature that allows us, subject to credit availability and certain other conditions, to increase the amount of the revolving credit facility, together with any added term loans, by up to $500.0 million in the aggregate. As of June 30, 2025, we had no borrowings outstanding under our revolving credit facility. We have a $200.0 million letter of credit sublimit as part of the revolving credit facility. The amount available to be borrowed under the revolving credit facility is reduced on a dollar-for-dollar basis by the cumulative amount of any outstanding letters of credit, which was $0.8 million at June 30, 2025, leaving a borrowing capacity under our credit agreement of $1.9 billion at June 30, 2025.
Our revolving credit facility provides for a commitment fee on undrawn amounts ranging from 0.125% to 0.20% and interest on borrowings at SOFR plus a credit spread adjustment of 0.10% or the base rate, in each case plus an applicable margin. The applicable margin ranges from 1.125% to 1.50% for SOFR borrowings and 0.125% to 0.50% for base rate borrowings. The interest rate charged for our revolving credit facility is affected by our leverage ratio.
Within the meaning of Regulation S-X, Rule 3-10, AutoNation, Inc. (the parent company) has no independent assets or operations. If guarantees of our subsidiaries were to be issued under our existing registration statement, we expect that such guarantees would be full and unconditional and joint and several, and any subsidiaries other than the guarantor subsidiaries would be minor.
Other Long-Term Debt
At June 30, 2025, we had finance leases and other debt obligations of $355.6 million, which are due at various dates through 2041.
Commercial Paper
We have a commercial paper program pursuant to which we may issue short-term, unsecured commercial paper notes on a private placement basis up to a maximum aggregate amount outstanding at any time of $1.9 billion. The interest rate for the commercial paper notes varies based on duration and market conditions. The maturities of the commercial paper notes may vary, but may not exceed 397 days from the date of issuance. Proceeds from the issuance of commercial paper notes are used to repay borrowings under the revolving credit facility, to finance acquisitions, and for strategic initiatives, working capital, capital expenditures, share repurchases, and/or other general corporate purposes. We use the revolving credit facility under our credit agreement as a liquidity backstop for borrowings under the commercial paper program. A downgrade in our credit ratings could negatively impact our ability to issue, or the interest rates for, commercial paper notes.
At June 30, 2025, we had $130.0 million of commercial paper notes outstanding with a weighted-average annual interest rate of 4.8% and a weighted-average remaining term of 1 day. At December 31, 2024, we had $630.0 million of commercial paper notes outstanding with a weighted-average annual interest rate of 4.9% and a weighted-average remaining term of 9 days.
Non-Recourse Debt
Non-recourse debt relates to financed auto loans receivable of our captive auto finance company funded through a combination of warehouse facilities, asset-backed term funding transactions, and free cash flows from operations.
Non-recourse debt outstanding at June 30, 2025, and December 31, 2024, consisted of the following:
June 30,
2025		December 31, 2024
Warehouse facilities$777.9 $801.5 
Term securitization debt of consolidated VIEs690.1 24.7 
1,468.0 826.2 
Less: unamortized debt discounts and debt issuance costs(3.4)(0.2)
Less: current maturities (45.0)(28.3)
Non-recourse debt, net of current maturities $1,419.6 $797.7 
The timing of principal payments on the non-recourse debt is based on the timing of principal collections and defaults on the related auto loans receivable. The current portion of non-recourse debt represents the portion of the payments received from the auto loans receivable that are due to be distributed as principal payments on the non-recourse debt in the following period.
We recognize transfers of auto loans receivable into the warehouse facilities and term securitizations (together, “non-recourse debt”) as secured borrowings, which result in recording the auto loans receivable and the related non-recourse debt on our Unaudited Condensed Consolidated Balance Sheets. The non-recourse debt is structured to legally isolate the auto loans receivable, which can only be used as collateral to settle obligations of the related non-recourse debt. The term securitization trusts and investors and the creditors of the warehouse facilities have no recourse to our assets for payment of the debt beyond the related auto loan receivables, the amounts on deposit in reserve accounts, and the restricted cash from collections on auto loans receivable.
Warehouse Facilities
We have three warehouse facility agreements with certain banking institutions through wholly-owned, bankruptcy-remote, special purpose entities, primarily to finance the purchase and origination of auto loans receivable. We fund auto loans receivable through these warehouse facilities, which are secured by the eligible auto loans receivable pledged as collateral.
We generally enter into warehouse facility agreements for one-year terms and typically renew the agreements annually. At June 30, 2025, our warehouse facilities utilized SOFR-based interest rates, as well as interest rates based on a lender’s asset-backed commercial paper conduit. Our warehouse facilities had a weighted-average interest rate of 5.3% at June 30, 2025, and 5.4% at December 31, 2024. The aggregate capacities under our warehouse facilities as of June 30, 2025, were as follows:
June 30,
2025
Warehouse facilities:
August 2025 expiration

October 2025 expiration
300.0 
May 2026 expiration
700.0 
Aggregate capacity $1,400.0 
Unused capacity$622.1 
The remaining borrowing capacity of $622.1 million was limited to $0.5 million based on the eligible auto loans receivable that have been pledged as collateral.
Term Securitizations
We have asset-backed term securitizations that were put in place to provide long-term funding for certain auto loans receivable initially funded through the warehouse facilities. In these transactions, a pool of auto loans receivable is sold to a bankruptcy-remote, special purpose entity that, in turn, transfers the receivables to a special purpose securitization trust (“term securitization trust”). The term securitization trust issues asset-backed securities, secured or otherwise supported by the transferred receivables, and the proceeds from the sale of the asset-backed securities are used to finance the securitized receivables.
We are required to evaluate the term securitization trusts for consolidation. We retain the servicing rights for the auto loans receivable that were funded through the term securitizations. In our capacity as servicer of the underlying auto loans receivable, we have the power to direct the activities of the trusts that most significantly impact the economic performance of the trusts. In addition, we have the obligation to absorb losses (subject to limitations) and the rights to receive any returns of the trusts, which could be significant. Accordingly, we are the primary beneficiary of the trusts and are required to consolidate them.
In May 2025, we issued $700.0 million in non-recourse notes payable related to asset-backed term securitizations. At June 30, 2025, non-recourse notes payable consisted of the following:

Total non-recourse notes payable
$690.1 $735.1 
Term securitization debt is expected to become due and be paid prior to the final legal maturities based on amortization of the auto loans receivable pledged as collateral. The term securitization agreements require certain funds to be held in restricted cash accounts to provide additional collateral for the borrowings or to be applied to make payments on the securitization debt. Restricted cash of consolidated VIEs under the various term securitization agreements totaled $30.1 million as of June 30, 2025, and $3.4 million as of December 31, 2024, and is included in Other Current Assets and Other Assets in our Unaudited Condensed Consolidated Balance Sheets. Auto loans receivable pledged to the term securitization debt of consolidated VIEs totaled $687.1 million as of June 30, 2025, and $24.5 million as of December 31, 2024.
In July 2025, we repaid the outstanding balance of non-recourse notes payable of the CIG Auto Receivables Trust 2021-1.

Income Taxes INCOME TAXES
Income taxes payable included in Other Current Liabilities totaled $4.3 million and $69.0 million at June 30, 2025 and December 31, 2024, respectively. The income tax provision for the three and six months ended June 30, 2025 reflects the fact that the goodwill impairment charge recorded in the second quarter of 2025 was not deductible for income tax purposes. See Note 8 of the Notes to Unaudited Condensed Consolidated Financial Statements for more information.
We file income tax returns in the U.S. federal jurisdiction and various states. As a matter of course, various taxing authorities, including the IRS, regularly audit us. These audits may culminate in proposed assessments which may ultimately result in our owing additional taxes. With few exceptions, we are no longer subject to U.S. federal, state, and local income tax examinations by tax authorities for years before 2020. Currently, no tax years are under examination by the IRS and tax years from 2021 to 2022 are under examination by U.S. state jurisdictions. We believe that our tax positions comply with applicable tax law and that we have adequately provided for these matters.
It is our policy to account for interest and penalties associated with income tax obligations as a component of Income Tax Provision in the accompanying Unaudited Condensed Consolidated Statements of Income.

Financial Instruments and Fair Value Measurements

Fair Value Disclosures [Abstract]  
Financial Instruments and Fair Value Measurements FINANCIAL INSTRUMENTS AND FAIR VALUE MEASUREMENTS
The fair value of a financial instrument represents the amount at which the instrument could be exchanged in a current transaction between willing parties, other than in a forced sale or liquidation. Fair value estimates are made at a specific point in time based on relevant market information about the financial instrument. These estimates are subjective in nature and involve uncertainties and matters of judgment, and therefore cannot be determined with precision.
Accounting standards define fair value as the price that would be received from selling an asset or paid to transfer a liability in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants at the measurement date. Accounting standards establish a fair value hierarchy which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value and also establishes the following three levels of inputs that may be used to measure fair value:
Level 1Quoted prices (unadjusted) in active markets for identical assets or liabilities that a reporting entity can access at the measurement date
Level 2Inputs other than quoted prices in active markets for identical assets and liabilities that are observable either directly or indirectly
Level 3Unobservable inputs
The following methods and assumptions were used by us in estimating fair value disclosures for financial instruments:
•Cash and cash equivalents, receivables, other current assets, vehicle floorplan payable, accounts payable, other current liabilities, commercial paper, warehouse credit facilities, and variable rate debt: The amounts reported in the accompanying Unaudited Condensed Consolidated Balance Sheets approximate fair value due to their short-term nature or the existence of variable interest rates that approximate prevailing market rates.
•Auto loans receivable, net: Auto loans receivable are presented net of an allowance for expected credit losses, which we believe approximates fair value.
•Investments in Equity Securities: Our equity investments with readily determinable fair values are measured at fair value using Level 1 inputs, which totaled $10.2 million at June 30, 2025, and $20.0 million at December 31, 2024.
Our equity investments that do not have a readily determinable fair value are measured using the measurement alternative as permitted by accounting standards and were recorded at cost, to be subsequently adjusted for observable price changes. The carrying amounts of our equity investments without a readily determinable fair value totaled $50.3 million at June 30, 2025, and $49.8 million at December 31, 2024. Equity investments that do not have a readily determinable fair value reflect cumulative downward adjustments of $8.4 million and cumulative upward adjustments of $3.4 million based on observable price changes. We did not record any upward adjustments or impairments during the six months ended June 30, 2025.
Investments in equity securities are reported in Other Current Assets and Other Assets in the accompanying Unaudited Condensed Consolidated Balance Sheets. Realized and unrealized gains and losses are reported in Other Income (Loss), Net (non-operating) in the Unaudited Condensed Consolidated Statements of Income and in the “Corporate and other” category of our segment information.

•Fixed rate long-term debt: Our fixed rate long-term debt consists primarily of amounts outstanding under our senior unsecured notes. We estimate the fair value of our senior unsecured notes using quoted prices for the identical liability (Level 1). A summary of the aggregate carrying values and fair values of our senior unsecured notes is as follows:
June 30,
2025		December 31,
2024
Carrying value$3,279.0 $2,782.1 
Fair value$3,156.2 $2,578.6 
Nonfinancial assets such as goodwill, other intangible assets, and long-lived assets held and used, are measured at fair value when there is an indicator of impairment and recorded at fair value only when impairment is recognized or for a business combination. The fair values less costs to sell of long-lived assets and disposal groups held for sale are assessed each reporting
period they remain classified as held for sale. Subsequent changes in the held for sale long-lived asset’s or disposal group’s fair value less cost to sell (increase or decrease) are reported as an adjustment to its carrying amount, except that the adjusted carrying amount cannot exceed the carrying amount of the long-lived asset or disposal group at the time it was initially classified as held for sale.

Goodwill
Goodwill for our reporting units is tested for impairment annually as of April 30 or more frequently when events or changes in circumstances indicate that the carrying value of a reporting unit more likely than not exceeds its fair value. Under accounting standards, we chose to make a qualitative evaluation about the likelihood of goodwill impairment as of April 30, 2025, for our Domestic, Import, Premium Luxury, AutoNation Finance, and Collision Center reporting units and determined that it was not more likely than not that the fair values of these reporting units were less than their carrying amounts. For our Mobile Service reporting unit, which relates to the mobile automotive repair and maintenance start-up business we acquired in the first quarter of 2023, we elected to perform a quantitative goodwill impairment test as of April 30, 2025.
As a result of the quantitative test, we determined that the fair value of the Mobile Service reporting unit was less than its carrying value and we recorded a non-cash goodwill impairment charge of $65.3 million during the three months ended June 30, 2025. The decline in the fair value of the Mobile Service reporting unit reflects updated expectations of performance, which resulted in a reduction in forecasted cash flows and growth rates used to estimate fair value. The non-cash impairment charge is reflected as Goodwill Impairment in the accompanying Unaudited Condensed Consolidated Statements of Income and in the “Corporate and other” category of our segment information.
The quantitative goodwill impairment test requires a determination of whether the fair value of a reporting unit is less than its carrying value. We estimate the fair value of our reporting units using an “income” valuation approach, which discounts projected free cash flows of the reporting unit at a computed weighted average cost of capital as the discount rate. The income valuation approach requires the use of significant estimates and assumptions, which include the revenue growth rates and future operating margins used to calculate projected future cash flows, weighted average costs of capital, and future economic and market conditions. In connection with this process, we also reconcile the estimated aggregate fair values of our reporting units to our market capitalization, including consideration of a control premium that represents the estimated amount an investor would pay for our equity securities to obtain a controlling interest. We believe that this reconciliation process is consistent with a market participant perspective. We base our cash flow forecasts on our knowledge of the automotive industry, our recent performance, our expectations of our future performance, and other assumptions we believe to be reasonable but that are unpredictable and inherently uncertain. Actual future results may differ from those estimates. We also make certain judgments and assumptions in allocating shared assets and liabilities to determine the carrying values for each of our reporting units.
We chose to perform quantitative tests for our annual goodwill impairment testing as of April 30, 2024, and no impairment charges resulted from these quantitative tests.
Other Intangible Assets
Our principal identifiable intangible assets are individual store rights under franchise agreements with vehicle manufacturers, which have indefinite lives and are tested for impairment annually as of April 30 or more frequently when events or changes in circumstances indicate that impairment may have occurred.
We elected to perform quantitative franchise rights impairment tests as of April 30, 2025. As a result of the quantitative tests, we determined the franchise rights carrying values for nine stores, primarily Domestic franchises, exceeded their fair values, and we recorded non-cash franchise rights impairment charges of $71.7 million to reduce the carrying value of the stores’ franchise agreements to their estimated fair values. The decline in the fair value of rights under these stores’ franchise agreements reflects the underperformance relative to expectations of these stores, as well as our expectations for the stores’ future prospects. These factors resulted in a reduction in forecasted cash flows and growth rates used to estimate fair value. The non-cash impairment charges are recorded as Franchise Rights Impairment in the accompanying Consolidated Statements of Income and in the “Corporate and other” category of our segment information.
We elected to perform quantitative franchise rights impairment tests for our annual impairment tests as of April 30, 2024 and no impairment charges resulted from these quantitative tests.
Long-Lived Assets and Right-of-Use Assets
Fair value measurements for our long-lived assets and right-of-use assets are based on Level 3 inputs. Changes in fair value measurements are reviewed and assessed each quarter for properties and disposal groups classified as held for sale, or when an indicator of impairment exists for properties classified as held and used or for right-of-use assets. The valuation process is generally based on a combination of the market and replacement cost approaches. In certain cases, fair value measurements are based on pending agreements to sell the related assets.
In a market approach, we use transaction prices for comparable properties that have recently been sold. These transaction prices are adjusted for factors related to a specific property. We evaluate changes in local real estate markets, and/or recent market interest or negotiations related to a specific property. In a replacement cost approach, the cost to replace a specific long-lived asset is considered, which is adjusted for depreciation from physical deterioration, as well as functional and economic obsolescence, if present and measurable.
To validate the fair values determined under the valuation process noted above, we also obtain independent third-party appraisals for our properties and/or third-party brokers’ opinions of value, which are generally developed using the same valuation approaches described above, and we evaluate any recent negotiations or discussions with third-party real estate brokers related to a specific long-lived asset or market. 
The non-cash impairment charges related to long-lived assets are included in Other Expense, Net in our
Unaudited Condensed Consolidated Statements of Income and in the “Corporate and other” category of our segment
information.
We had assets held for sale of $78.4 million as of June 30, 2025, and $23.6 million as of December 31, 2024, primarily related to inventory, goodwill, and property of disposal groups held for sale, as well as property held for sale. Assets held for sale are included in Other Current Assets in our Unaudited Condensed Consolidated Balance Sheets.

Commitments And Contingencies COMMITMENTS AND CONTINGENCIES
Legal Proceedings
We are involved, and will continue to be involved, in numerous legal proceedings arising out of the conduct of our business, including litigation with customers, third-party dealers, wage and hour and other employment-related lawsuits, and actions brought by governmental authorities. Some of these lawsuits purport or may be determined to be class or collective actions and seek substantial damages or injunctive relief, or both, and some may remain unresolved for several years. We establish accruals for specific legal proceedings when it is considered probable that a loss has been incurred and the amount of the loss can be reasonably estimated. Our accruals for loss contingencies are reviewed quarterly and adjusted as additional information becomes available. We disclose the amount accrued if material or if such disclosure is necessary for our financial statements to not be misleading. If a loss is not both probable and reasonably estimable, or if an exposure to loss exists in excess of the amount accrued, we assess whether there is at least a reasonable possibility that a loss, or additional loss, may have been incurred. If there is a reasonable possibility that a loss, or additional loss, may have been incurred, we disclose the estimate of the possible loss or range of loss if it is material or a statement that such an estimate cannot be made. Our evaluation of whether a loss is reasonably possible or probable is based on our assessment and consultation with legal counsel regarding the ultimate outcome of the matter.
As of June 30, 2025 and 2024, we have accrued for the potential impact of loss contingencies that are probable and reasonably estimable, and there was no indication of a reasonable possibility that a material loss, or additional material loss, may have been incurred. We do not believe that the ultimate resolution of these matters will have a material adverse effect on our results of operations, financial condition, or cash flows. However, the results of these matters cannot be predicted with certainty, and an unfavorable resolution of one or more of these matters could have a material adverse effect on our results of operations, financial condition, or cash flows.
Other Matters
In connection with the CDK outage previously discussed in our Annual Report on Form 10-K for the fiscal year ended December 31, 2024, in the first quarter of 2025, we submitted claims under our cyber insurance policies seeking recovery for estimated business interruption and related losses caused by the CDK outage. In July 2025, we received insurance recoveries of $10 million in connection with the CDK outage. Although we expect to receive additional insurance recoveries in connection with the CDK outage, there can be no assurance as to the amount or timing of any potential additional recovery.
AutoNation, acting through its subsidiaries, is the lessee under many real estate leases that provide for the use by our subsidiaries of their respective store premises. Pursuant to these leases, we agree to indemnify the lessor and other related parties from certain liabilities arising as a result of the use of the leased premises, including environmental liabilities, or a breach of the lease by the lessee. Additionally, from time to time, we enter into agreements with third parties in connection with the sale of assets or businesses in which we agree to indemnify the purchaser or related parties from certain liabilities or costs arising in connection with the assets or business. Also, in the ordinary course of business in connection with purchases or sales of goods and services, we enter into agreements that may contain indemnification provisions. In the event that an indemnification claim is asserted, our liability would be limited by the terms of the applicable agreement.
From time to time, primarily in connection with dispositions of automotive stores, we assign or sublet to the store purchaser our interests in any real property leases associated with such stores. In general, we retain responsibility for the performance of certain obligations under such leases to the extent that the assignee or sublessee does not perform, whether such performance is required prior to or following the assignment or subletting of the lease. Additionally, we generally remain subject to the terms of any guarantees made by us in connection with such leases. We generally have indemnification rights against the assignee or sublessee in the event of non-performance under these leases, as well as certain defenses. We presently have no reason to believe that we will be called on to perform under any such remaining assigned leases or subleases. We estimate that lessee rental payment obligations during the remaining terms of these leases with expirations ranging from 2027 to 2034 are approximately $4 million at June 30, 2025. There can be no assurance that any performance required of us under these leases would not have a material adverse effect on our business, financial condition, and cash flows.
At June 30, 2025, surety bonds, letters of credit, and cash deposits totaled $111.7 million, of which $0.8 million were letters of credit. In the ordinary course of business, we are required to post performance and surety bonds, letters of credit, and/or cash deposits as financial guarantees of our performance. We do not currently provide cash collateral for outstanding letters of credit.
In the ordinary course of business, we are subject to numerous laws and regulations, including automotive, environmental, health and safety, and other laws and regulations. We do not anticipate that the costs of compliance with such laws will have a material adverse effect on our business, results of operations, cash flows, or financial condition, although such outcome is possible given the nature of our operations and the extensive legal and regulatory framework applicable to our business. We do not have any material known environmental commitments or contingencies.

Risks and Uncertainties [Abstract]  
Business And Credit Concentrations BUSINESS AND CREDIT CONCENTRATIONS
We own and operate franchised automotive stores in the United States pursuant to franchise agreements with vehicle manufacturers. During the six months ended June 30, 2025, approximately 65% of our total retail new vehicle unit sales was generated by our stores in Florida, California, and Texas.
We are subject to a concentration of risk in the event of financial distress of or other adverse event related to a major vehicle manufacturer or related lender or supplier. The core brands of vehicles that we sell, representing approximately 88% of the new vehicles that we sold during the six months ended June 30, 2025, are manufactured by Toyota (including Lexus), Honda, Ford, General Motors, BMW, Mercedes-Benz, Stellantis, and Volkswagen (including Audi and Porsche). Our business could be materially adversely impacted by a bankruptcy of or other adverse event related to a major vehicle manufacturer or related lender or supplier.
We are also subject to a concentration of risk in the event of the non-performance of third-party information technology service providers, such as the provider of our dealer management system on which we significantly rely to operate our business.
We had receivables from manufacturers or distributors of $218.5 million at June 30, 2025, and $267.1 million at December 31, 2024. Additionally, a large portion of our contracts-in-transit included in Receivables, net, in the accompanying Unaudited Condensed Consolidated Balance Sheets, are due from automotive manufacturers’ captive finance subsidiaries, which provide financing directly to our new and used vehicle customers. Concentrations of credit risk with respect to non-manufacturer trade receivables are limited due to the wide variety of customers and markets in which our products are sold as well as their dispersion across many different geographic areas in the United States. Consequently, at June 30, 2025, we do not consider AutoNation to have any significant non-manufacturer concentrations of credit risk.

Segment Reporting [Abstract]  
Segment Information SEGMENT INFORMATION
At June 30, 2025, we had four reportable segments: (1) Domestic, (2) Import, (3) Premium Luxury, and (4) AutoNation Finance. Our Domestic segment is comprised of retail automotive franchises that sell new vehicles manufactured by Ford, General Motors, and Stellantis. Our Import segment is primarily comprised of retail automotive franchises that sell new vehicles manufactured by Toyota, Honda, Hyundai, Subaru, and Nissan. Our Premium Luxury segment is primarily comprised of retail automotive franchises that sell new vehicles manufactured by Mercedes-Benz, BMW, Lexus, Audi, and Jaguar Land Rover. The franchises in each of our Domestic, Import, and Premium Luxury segments also sell used vehicles, parts and automotive services, and automotive finance and insurance products. Our AutoNation Finance segment is comprised of our captive auto finance company, which provides indirect financing to qualified retail customers on vehicles we sell.
“Corporate and other” is comprised of our non-franchised businesses, including AutoNation USA used vehicle stores, collision centers, parts distribution centers, auction operations, and our mobile automotive repair and maintenance business, all of which generate revenues but do not meet the quantitative thresholds for reportable segments, as well as unallocated corporate overhead expenses, goodwill and franchise right impairments, and other income items.
The reportable segments identified above are the business activities of the Company for which discrete financial information is available and for which operating results are regularly reviewed by our chief operating decision maker (“CODM”) to allocate resources and assess performance. Our CODM for each of our reportable segments is our Chief Executive Officer. For the Domestic, Import, and Premium Luxury segments, our CODM uses Franchised Dealerships - Segment Income (defined as operating income less floorplan expense) to allocate resources to each of these segments during our annual budgeting process. Our CODM evaluates Franchised Dealerships - Segment Income actual results versus budget and prior year on a monthly basis when making decisions about allocating resources to these segments and whether to reinvest profits into each of these segments or into other parts of the Company, such as for acquisitions, strategic initiatives, or share repurchases. Our CODM also uses Franchised Dealerships - Segment Income to assess the underlying operating performance of each of these segments by comparing the results and return on investment for each of these segments.
Our CODM uses AutoNation Finance Income (Loss) to allocate capital resources to the AutoNation Finance segment in our annual budgeting process and uses that measure as a basis to evaluate the underlying operating performance of this segment by monitoring the margin between interest revenue and interest expense, credit program tier distribution, portfolio quality, and the overall performance of the loan portfolio for the segment.
The following tables provide segment revenues and segment expenses that align with the segment-level information that is regularly provided to our CODM:

Organization, Consolidation and Presentation of Financial Statements [Abstract]  
Basis of Presentation
The accompanying Unaudited Condensed Consolidated Financial Statements include the accounts of AutoNation, Inc. and its subsidiaries; intercompany accounts and transactions have been eliminated. The accompanying Unaudited Condensed Consolidated Financial Statements have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) for interim financial information and in accordance with the rules and regulations of the Securities and Exchange Commission (“SEC”). Accordingly, they do not include all of the information and notes required by GAAP for complete financial statements. Additionally, operating results for interim periods are not necessarily indicative of the results that can be expected for a full year. The Unaudited Condensed Consolidated Financial Statements herein should be read in conjunction with our audited Consolidated Financial Statements and notes thereto included within our most recent Annual Report on Form 10-K. These Unaudited Condensed Consolidated Financial Statements reflect, in the opinion of management, all material adjustments (which include only normal recurring adjustments) necessary to fairly state, in all material respects, our financial position and results of operations for the periods presented.
Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. In preparing these financial statements, management has made its best estimates and judgments of certain amounts included in the financial statements. We base our estimates and judgments on historical experience and other assumptions that we believe are reasonable. However, application of these accounting policies involves the exercise of judgment and use of assumptions as to future uncertainties and, as a result, actual results could differ materially from these estimates. We periodically evaluate estimates and assumptions used in the preparation of the financial statements and make changes on a prospective basis when adjustments are necessary. Such estimates and assumptions affect, among other things, our goodwill, indefinite-lived intangible asset, and long-lived asset valuations; inventory valuation; equity investment valuation; assets held for sale; assessments of variable consideration and related constraints associated with retrospective commissions; accruals for chargebacks against revenue recognized from the sale of finance and insurance products; accruals related to self-insurance programs; certain legal proceedings; assessment of the annual income tax expense; valuation of deferred income taxes and income tax contingencies; the allowance for expected credit losses; and measurement of performance-based compensation costs.
Recent Accounting Pronouncements
In December 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standard Update (“ASU”) 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures, that 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. The amendments in this accounting standard are effective for annual periods beginning after December 15, 2024, on a prospective basis. Early adoption and retrospective application are permitted. We do not expect the adoption of this accounting standard to have an impact on our consolidated financial statements, but will require certain additional 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, that requires disclosure of the amounts of purchases of inventory, employee compensation, depreciation, and intangible asset amortization included in each relevant expense line item on the income statement. The standard also requires a qualitative description of other amounts included in each relevant expense line item on the income statement that are not separately disclosed. In addition, entities are required to disclose the nature and amount of selling expenses. The new standard is effective for annual reporting periods beginning after December 15, 2026, and interim reporting periods beginning after December 15, 2027. Early adoption is permitted. We do not expect the adoption of this accounting standard to have an impact on our consolidated financial statements, but will require certain additional disclosures.
Earnings Per Share Basic earnings per share (“EPS”) is computed by dividing net income by the weighted average number of common shares outstanding for the period, including vested restricted stock unit (“RSU”) awards. Diluted EPS is calculated using the treasury stock method by dividing net income by the weighted average number of shares outstanding, noted above, including the dilutive effect of unvested RSU awards.
Allowance for Credit Losses
The allowance for credit losses represents the net credit losses expected over the remaining contractual life of our auto loans receivable. The allowance for credit losses is determined using a vintage-level statistical model that captures the relationship between historical changes in gross losses and the lifetime loss curves by month on book, credit tiers at origination, and seasonality, adjusted for expected recoveries based on historical recovery trends. The credit loss model also incorporates reasonable and supportable forecasts about the future utilizing a forecast of a macroeconomic variable, specifically, the change in U.S. disposable personal income, which we believe is most strongly correlated to evaluating and predicting expected credit losses of our auto loans receivable. We utilize a reasonable and supportable forecast period of one year, after which we immediately revert to historical experience.
We periodically consider whether the use of alternative variables would result in improved credit loss model accuracy and revise the model when appropriate. We also consider whether qualitative adjustments are necessary for factors that are not reflected in the quantitative methods but impact the measurement of estimated credit losses. Such adjustments include the expectations of the impact of recent economic trends on customer behavior.
Impairment of Long-Lived Assets
Nonfinancial assets such as goodwill, other intangible assets, and long-lived assets held and used, are measured at fair value when there is an indicator of impairment and recorded at fair value only when impairment is recognized or for a business combination. The fair values less costs to sell of long-lived assets and disposal groups held for sale are assessed each reporting
period they remain classified as held for sale. Subsequent changes in the held for sale long-lived asset’s or disposal group’s fair value less cost to sell (increase or decrease) are reported as an adjustment to its carrying amount, except that the adjusted carrying amount cannot exceed the carrying amount of the long-lived asset or disposal group at the time it was initially classified as held for sale.

Earnings per share for the three and six months ended June 30, 2025, was adversely impacted by non-cash goodwill and franchise rights impairments. See Notes 8 and 14 of the Notes to Unaudited Condensed Consolidated Financial Statements for more information.
In June 2024, our business was impacted by an outage of our dealer management system provided by CDK Global, which is used to support our dealership operations, including our sales, service, inventory, customer relationship management, and accounting functions. As a result, our results of operations and earnings per share for the three and six months ended June 30, 2024, were negatively impacted by lost income from the disruption to our operations and one-time compensation costs paid to commission-based associates to ensure business continuity.
