AUTONATION, INC. (AN)

Overview

AutoNation, Inc., through its subsidiaries, is one of the largest automotive retailers in the United States. As of June 30, 2026, we owned and operated 327 new vehicle franchises from 246 stores located in the United States, predominantly in major metropolitan markets in the Sunbelt region. Our stores, which we believe include some of the most recognizable and well known in our key markets, sell 30 different new vehicle brands. The major brands of new vehicles that we sell, representing approximately 88% of the new vehicles that we sold during the six months ended June 30, 2026, are manufactured by Toyota (including Lexus), Honda, Ford, General Motors, BMW, Mercedes-Benz, Stellantis, and Volkswagen (including Audi and Porsche). As of June 30, 2026, we also owned and operated 52 AutoNation-branded collision centers, 24 AutoNation USA stores, 4 AutoNation-branded automotive auction operations, 3 parts distribution centers, 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 in-store and mobile 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.

At June 30, 2026, 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, and Subaru. 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. AutoNation Finance is our captive auto finance company, which provides indirect financing to qualified retail customers on vehicles we sell.

For the six months ended June 30, 2026, new vehicle sales accounted for 47% of our total revenue and 12% of our total gross profit. Used vehicle sales accounted for 29% of our total revenue and 10% of our total gross profit. Our parts and service operations, while comprising 18% of our total revenue, contributed 49% of our total gross profit. Our finance and insurance sales, while comprising 5% of our total revenue, contributed 29% of our total gross profit.

Market Conditions

In the second quarter of 2026, U.S. industry retail new vehicle unit sales, which includes sales in markets in which we do not compete, was relatively flat, with a decrease in April offset by increases in May and June, as compared to the same periods in the second quarter of 2025. New vehicle unit sales benefited from accelerated consumer demand in April 2025 following tariff-related announcements, and consumer demand and industry new vehicle unit sales stabilized in the later part of the second quarter of 2025.

Results of Operations

During the three months ended June 30, 2026, we had net income of $182.1 million and diluted earnings per share of $5.39, as compared to net income of $86.4 million and diluted earnings per share of $2.26 during the same period in 2025.

Our total gross profit decreased 3% during the second quarter of 2026, compared to the same period in the prior year, driven by decreases in new vehicle gross profit of 18%, used vehicle gross profit of 8%, and finance and insurance gross profit of 3%, partially offset by an increase in parts and service gross profit of 1%, each as compared to the second quarter of 2025. New vehicle gross profit was adversely impacted by a decrease in new vehicle unit volume as the prior year benefited from accelerated consumer demand following tariff-related announcements in April 2025 and a decrease in electric vehicle (“EV”)

unit volume in the current year period due in part to the phasing out of EV tax credits at the end of the third quarter of 2025, as well as a decrease in gross profit per vehicle retailed (“PVR”) resulting from higher average vehicle costs. Used vehicle gross profit was adversely impacted by a decrease in used vehicle retail unit volume primarily due to supply constraints on lower-priced used vehicles. Finance and insurance gross profit was adversely impacted by a decrease in vehicle unit volume, largely offset by an increase in finance and insurance gross profit PVR reflecting higher realized margins on vehicle service contracts and higher gross profit per transaction associated with arranging customer financing. Parts and service results benefited primarily from increases in gross profit associated with customer-pay service of 7% and wholesale parts sales of 9%.

Net income for the three months ended June 30, 2026, was adversely impacted by after-tax asset impairments, net of gains on property and store dispositions, of $2.4 million and an after-tax net loss from operations of terminated stores of $3.3 million. Net income for the three months ended June 30, 2025, was adversely impacted by non-cash goodwill and franchise rights impairments and other asset adjustments totaling $122.8 million after-tax.

Inventory Management

Our new and used vehicle inventories are stated at the lower of cost or net realizable value in our Unaudited Condensed Consolidated Balance Sheets. We monitor our vehicle inventory levels based on current economic conditions and seasonal sales trends.

Our new vehicle inventory units at June 30, 2026 and 2025, were 45,283 and 42,600, respectively. We have typically not experienced significant losses on the sale of new vehicle inventory, in part due to incentives provided by manufacturers to promote sales of new vehicles and our inventory management practices. We monitor our new vehicle inventory values as compared to net realizable values. Our new vehicle inventory was net of cumulative write-downs of $0.2 million at June 30, 2026, and $1.2 million at December 31, 2025.

Our used vehicle inventory units at June 30, 2026 and 2025, were 34,777 and 35,802, respectively. We recondition the majority of used vehicles acquired for retail sale in our parts and service departments and capitalize the related costs to the used vehicle inventory. We monitor our used vehicle inventory values as compared to net realizable values. Typically, used vehicles that are not sold on a retail basis are sold at wholesale auctions. Our used vehicle inventory balance was net of cumulative write-downs of $5.7 million at June 30, 2026, and $5.8 million at December 31, 2025.

Parts, accessories, and other inventory are carried at the lower of cost or net realizable value. We estimate the amount of potentially damaged and/or excess and obsolete inventory based upon historical experience, manufacturer return policies, and industry trends. Our parts, accessories, and other inventory balance was net of cumulative write-downs of $9.0 million at June 30, 2026, and $9.5 million at December 31, 2025.

Critical Accounting Estimates

We prepare our Unaudited Condensed Consolidated Financial Statements in conformity with U.S. generally accepted accounting principles (“GAAP”), which require us to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities as of the date of the financial statements, and the reported amounts of revenue and expenses during the reporting period. We evaluate our estimates on an ongoing basis, and we base our estimates on historical experience and various other assumptions we believe to be reasonable. Actual outcomes could differ materially from those estimates in a manner that could have a material effect on our Unaudited Condensed Consolidated Financial Statements. For additional discussion of our critical accounting estimates, please see “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in our most recent Annual Report on Form 10-K.

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, 2026, 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, we elected to perform a quantitative goodwill impairment test as of April 30, 2026, and no impairment charges resulted from this quantitative test. The fair value of the Mobile Service reporting unit substantially exceeded its carrying value as of April 30, 2026. The quantitative goodwill impairment test is dependent on many variables used to determine the fair value of a reporting unit. See Note 15 of the Notes to Unaudited Condensed Consolidated Financial

Statements for additional information on how the fair values and carrying values of our reporting units are derived for the quantitative goodwill impairment test.

As of June 30, 2026, we have $221.5 million of goodwill related to the Domestic reporting unit, $538.5 million related to the Import reporting unit, $504.6 million related to the Premium Luxury reporting unit, $75.2 million related to the Mobile Service reporting unit, $78.4 million related to the AutoNation Finance reporting unit, and $4.6 million related to the Collision Center reporting unit.

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 may first perform a qualitative assessment to determine whether it is more likely than not that a franchise right asset is impaired. We elected to perform quantitative franchise rights impairment tests for our annual impairment tests as of April 30, 2026, and no impairment charges resulted from these quantitative tests. We identified 16 stores that, while they each had franchise rights fair value in excess of carrying value, had lower relative performance compared to our total store population. We will continue to monitor these stores, as well as all stores, for events or changes in circumstances that may indicate potential impairment. The remainder of our stores had franchise rights with calculated fair values that substantially exceeded their carrying values.

The quantitative franchise rights impairment test is dependent on many variables used to determine the fair value of each store’s franchise rights. See Note 15 of the Notes to Unaudited Condensed Consolidated Financial Statements for a description of the valuation method and related estimates and assumptions used in our quantitative impairment testing. Based on sensitivity analyses of these estimates and assumptions, including if the fair value of each of our franchise rights had been determined to be a hypothetical 10% lower as of the valuation date, the resulting hypothetical impairmen

Except to the extent that differences among reportable segments are material to an understanding of our business taken as a whole, we present the discussion in Management’s Discussion and Analysis of Financial Condition and Results of Operations on a consolidated basis.

Certain reclassifications of amounts previously reported have been made to the accompanying Consolidated Financial Statements in order to maintain consistency and comparability between periods presented.

Overview

AutoNation, Inc., through its subsidiaries, is one of the largest automotive retailers in the United States. As of December 31, 2025, we owned and operated 323 new vehicle franchises from 245 stores located in the United States, predominantly in major metropolitan markets in the Sunbelt region. Our stores, which we believe include some of the most recognizable and well known in our key markets, sell 30 different new vehicle brands. The core brands of new vehicles that we sell, representing approximately 89% of the new vehicles that we sold in 2025, are manufactured by Toyota (including Lexus), Honda, Ford, General Motors, BMW, Mercedes-Benz, Stellantis, and Volkswagen (including Audi and Porsche). As of December 31, 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 auto finance company on vehicles we sell.

As of December 31, 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, and Subaru. 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. AutoNation Finance is our captive auto finance company, which provides indirect financing to qualified retail customers on vehicles we sell.

For the year ended December 31, 2025, new vehicle sales accounted for 49% of our total revenue and 13% of our total gross profit. Used vehicle sales accounted for 28% of our total revenue and 9% of our total gross profit. Our parts and service operations, while comprising 17% of our total revenue, contributed 48% of our total gross profit. Our finance and insurance sales, while comprising 5% of our total revenue, contributed 30% of our total gross profit.

Market Conditions

Full-year U.S. industry new vehicle unit sales, which includes sales in markets in which we do not compete, were 16.3 million in 2025, as compared to 16.0 million in 2024, and 15.6 million in 2023. The higher levels of manufacturer vehicle production over the past several years led to an increased supply of new vehicle inventory, which has resulted in moderation of new vehicle unit profitability. We expect that new vehicle unit profitability may continue to moderate, in part due to the tariffs announced in 2025, as well as consumer concerns on vehicle affordability.

Table of Contents

The tariffs announced by the U.S. government beginning in the first quarter of 2025, and as may be modified in 2026 or beyond, on vehicles and parts imported from other countries could increase our costs and/or consumer prices and limit the availability of inventory and/or reduce demand for the products and services we offer, which in turn could have a material adverse effect on our business and results of operations. The policies and announcements regarding tariffs on imported goods have been evolving and remain highly fluid. The ultimate impact of any tariffs is uncertain and will depend on various factors, including whether the tariffs are maintained and/or implemented, the duration of the tariffs and the timing of their implementation, the amount, scope, and nature of the tariffs, and the related responses from other countries, manufacturers, and/or consumers.

The 2025 Budget Reconciliation Act (the “Act”), signed into law in July 2025, introduces several provisions with direct implications for the automotive retail industry, particularly in areas of taxation, consumer incentives, and electric vehicle policies. While we are encouraged by the potential uplift certain beneficial tax provisions of the Act may have on our business and the automotive retail industry, we currently do not expect the impact will be material to our results of operations.

Results of Operations

We had net income of $649.1 million and diluted earnings per share of $17.04 in 2025, as compared to net income of $692.2 million and diluted earnings per share of $16.92 in 2024.

Our total gross profit increased 3% during 2025, as compared to 2024, driven by increases in parts and service gross profit of 7% and finance and insurance gross profit of 8%, partially offset by a decrease in new vehicle gross profit of 14%. Parts and service results benefited primarily from increases in gross profit from customer-pay service and warranty service. Finance and insurance gross profit benefited from higher realized margins on vehicle service contracts and an increase in vehicle unit volume. New vehicle gross profit was adversely impacted by a decrease in gross profit per vehicle retailed (“PVR”) resulting from continued moderation of margins following post-pandemic elevated levels and higher average vehicle costs.

SG&A expenses increased primarily due to an increase in performance-driven compensation expense, which was partially offset by certain one-time compensation of approximately $43 million paid to commission-based associates in the prior year to ensure business continuity as a result of the CDK outage.

Net income and diluted earnings per share during 2025 were favorably impacted by after-tax gains on insurance recoveries of $60.5 million for business interruption and related losses caused by the CDK outage that occurred in June 2024. As a result of the CDK outage, we estimate earnings per share in 2024 was negatively impacted by approximately $2.17 per share, without taking into account any recoveries related to the incident. The estimated impact was comprised of internal estimates for lost income during the outage period and the one-time costs incurred related to the incident, described above.

In addition, net income and diluted earnings per share during 2025 were adversely impacted by non-cash goodwill and franchise rights impairments and other asset adjustments totaling $161.7 million after-tax. See Note 19 of the Notes to Consolidated Financial Statements for a discussion of the impairment charges.

Net income during 2024 benefited from an after-tax net gain of $35.3 million related to business/property dispositions, net of asset impairments, partially offset by after-tax franchise rights impairments of $9.4 million and after-tax self-insured losses of $8.8 million primarily related to weather-related catastrophes.

Inventory Management

Our new and used vehicle inventories are stated at the lower of cost or net realizable value in our Consolidated Balance Sheets. We monitor our vehicle inventory levels based on current economic conditions and seasonal sales trends.

Our new vehicle inventory units at December 31, 2025 and 2024, were approximately 43,800 and 42,600, respectively. We have typically not experienced significant losses on the sale of new vehicle inventory, in part due to incentives provided by manufacturers to promote sales of new vehicles and our inventory management practices. We monitor our new vehicle inventory values as compared to net realizable values. Our new vehicle inventory was net of cumulative write-downs of $1.2 million at December 31, 2025, and $2.0 million at December 31, 2024.

Table of Contents

Our used vehicle inventory units at December 31, 2025 and 2024, were approximately 33,100 and 34,000, respectively. We recondition the majority of used vehicles acquired for retail sale in our parts and service departments and capitalize the related costs to the used vehicle inventory. We monitor our used vehicle inventory values as compared to net realizable values. Typically, used vehicles that are not sold on a retail basis are sold at wholesale auctions. Our used vehicle inventory balance was net of cumulative write-downs of $5.8 million at December 31, 2025, and $7.8 million at December 31, 2024.

Parts, accessories, and other inventory are carried at the lower of cost or net realizable value. We estimate the amount of potentially damaged and/or excess and obsolete inventory based upon historical experience, manufacturer return policies, and industry trends. Our parts, accessories, and other inventory balance was net of cumulative write-downs of $9.5 million at December 31, 2025, and $8.3 million at December 31, 2024.

Critical Accounting Estimates

We prepare our Consolidated Financial Statements in conformity with U.S. generally accepted accounting principles (“U.S. GAAP”), which require us to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities as of the date of the financial statements, and the reported amounts of revenue and expenses during the reporting period. We evaluate our estimates on an ongoing basis and we base our estimates on historical experience and various other assumptions we believe to be reasonable. Actual outcomes could differ materially from those estimates in a manner that could have a material effect on our Consolidated Financial Statements. Set forth below are the accounting estimates that we have identified as critical to our business operations and an understanding of our results of operations, based on the high degree of judgment or complexity in their application. See Note 1 of the Notes to Consolidated Financial Statements for a discussion of other significant accounting policies.

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. We may first perform a qualitative assessment to determine whether it is more likel
