Organization, Consolidation and Presentation of Financial Statements [Abstract]
INTERIM FINANCIAL STATEMENTS	INTERIM FINANCIAL STATEMENTS Basis of Presentation These condensed Consolidated Financial Statements contain unaudited information as of June 30, 2024, and for the three and six months ended June 30, 2024 and 2023. The unaudited interim financial statements have been prepared pursuant to the rules and regulations for reporting on Form 10-Q. Accordingly, certain disclosures required by accounting principles generally accepted in the United States of America for annual financial statements are not included herein. In management’s opinion, these unaudited financial statements reflect all adjustments (which include only normal recurring adjustments) necessary for a fair presentation of the information when read in conjunction with our 2023 audited Consolidated Financial Statements and the related notes thereto. The financial information as of December 31, 2023, is derived from our Annual Report on Form 10-K filed with the Securities and Exchange Commission on February 23, 2024. The results of operations for the interim periods presented are not necessarily indicative of the results to be expected for the full year. Reclassifications Certain reclassifications of amounts previously reported have been made to the accompanying Consolidated Financial Statements to maintain consistency and comparability between periods presented. Within our financing operations income, we disaggregated our “lease income” out of our previously reported “interest, fee, and lease income” to be its own separately presented line item.

Receivables [Abstract]
FINANCE RECEIVABLES	FINANCE RECEIVABLES Interest income on finance receivables is recognized based on the contractual terms of each loan and is accrued until repayment, reaching non-accrual status, charge-off, or repossession. Direct costs associated with loan originations are capitalized and expensed as an offset to interest income when recognized on the loans.

FAIR VALUE MEASUREMENTS

FAIR VALUE MEASUREMENTS	6 Months Ended

Fair Value Disclosures [Abstract]
FAIR VALUE MEASUREMENTS	FAIR VALUE MEASUREMENTS Factors used in determining the fair value of our financial assets and liabilities are summarized into three broad categories: • Level 1 - quoted prices in active markets for identical securities; • Level 2 - other significant observable inputs, including quoted prices for similar securities, interest rates, prepayment spreads, credit risk; and • Level 3 - significant unobservable inputs, including our own assumptions in determining fair value. We determined the carrying value of cash equivalents, accounts receivable, trade payables, accrued liabilities, finance receivables, and short-term borrowings approximate their fair values because of the nature of their terms and current market rates of these instruments. We believe the carrying value of our variable rate debt approximates fair value. We have investments consisting of equity securities, available for sale debt securities, and equity method investments. We calculated the estimated fair value of the equity securities, equity method investments, and U.S. Treasury debt securities using quoted market prices (Level 1). The fair value of corporate and municipal debt securities are measured using observable Level 2 market expectations at each measurement date. See Note 6 – Investments. We have fixed rate debt primarily consisting of amounts outstanding under our senior notes, non-recourse notes payable, and real estate mortgages. We calculated the estimated fair value of the senior notes using quoted prices for the identical liability (Level 1). The fair value of non-recourse notes payable are measured using observable Level 2 market expectations at each measurement date. The calculated estimated fair values of the fixed rate real estate mortgages and finance lease liabilities use a discounted cash flow methodology with estimated current interest rates based on a similar risk profile and duration (Level 2). The fixed cash flows are discounted and summed to compute the fair value of the debt. We have derivative instruments consisting of an offsetting set of interest rate caps. The fair value of derivative assets and liabilities are measured using observable Level 2 market expectations at each measurement date and is recorded as other current assets, current liabilities and other long-term liabilities in the Consolidated Balance Sheets. Nonfinancial assets such as goodwill, franchise value, or other long-lived assets are measured and recorded at fair value during a business combination or when there is an indicator of impairment. We evaluate our goodwill and franchise value using a qualitative assessment process. If the qualitative factors determine that it is more likely than not that the carrying value exceeds the fair value, we would further evaluate for potential impairment using a quantitative assessment. The quantitative assessment estimates fair values using unobservable (Level 3) inputs by discounting expected future cash flows of the store for franchise value, or reporting unit for goodwill. The forecasted cash flows contain inherent uncertainties, including significant estimates and assumptions related to growth rates, margins, working capital requirements, and cost of capital, for which we utilize certain market participant-based assumptions we believe to be reasonable. We estimate the value of other long-lived assets that are recorded at fair value on a non-recurring basis on a market valuation approach. We use prices and other relevant information generated primarily by recent market transactions involving similar or comparable assets, as well as our historical experience in divestitures, acquisitions and real estate transactions. Additionally, we may use a cost valuation approach to value long-lived assets when a market valuation approach is unavailable. Under this approach, we determine the cost to replace the service capacity of an asset, adjusted for physical and economic obsolescence. When available, we use valuation inputs from independent valuation experts, such as real estate appraisers and brokers, to corroborate our estimates of fair value. Real estate appraisers’ and brokers’ valuations are typically developed using one or more valuation techniques including market, income and replacement cost approaches. Because these valuations contain unobservable inputs, we classified the measurement of fair value of long-lived assets as Level 3. There were no changes to our valuation techniques during the six-month period ended June 30, 2024. Below are our assets and liabilities that are measured at fair value: As of June 30, 2024 As of December 31, 2023 ($ in millions) Carrying Value Level 1 Level 2 Level 3 Carrying Value Level 1 Level 2 Level 3 Recorded at fair value Marketable securities Equity securities $ 2.1 $ 2.1 $ — $ — $ — $ — $ — $ — U.S. Treasury $ 19.9 $ 19.9 $ — $ — $ — $ — $ — $ — Municipal debt 9.6 — 9.6 — — — — — Corporate debt 19.8 — 19.8 — — — — — Total debt securities $ 49.3 $ 19.9 $ 29.4 $ — $ — $ — $ — $ — Equity Method Investment Pinewood Technologies Group PLC (PINE.L) $ 100.0 $ 100.0 $ — $ — $ — $ — $ — $ — Derivatives Derivative assets $ 8.9 $ — $ 8.9 $ — $ 12.3 $ — $ 12.3 $ — Derivative liabilities 8.9 — 8.9 — 12.3 — 12.3 — Recorded at historical value Fixed rate debt 1 4.625% Senior notes due 2027 $ 400.0 $ 379.5 $ — $ — $ 400.0 $ 380.0 $ — $ — 4.375% Senior notes due 2031 550.0 489.5 — — 550.0 492.3 — — 3.875% Senior notes due 2029 800.0 718.0 — — 800.0 716.0 — — Non-recourse notes payable 2,025.8 — 2,023.8 — 1,705.6 — 1,705.1 — Real estate mortgages and other debt 721.3 — 725.4 — 603.5 — 644.5 — 1 Excluding unamortized debt issuance costs

The following tables summarize the consideration paid for the 2024 acquisitions and the preliminary purchase price allocations for identified assets acquired and liabilities assumed as of the acquisition date: (in millions) Consideration Cash paid, net of cash acquired $ 1,169.5 Total consideration transferred $ 1,169.5 (in millions) Assets Acquired and Liabilities Assumed Accounts receivables, net $ 119.0 Inventories, net 999.5 Property and equipment 535.7 Operating lease right-of-use assets 289.8 Net investment in operating leases 181.5 Deferred taxes, net 20.5 Other assets 526.4 Floor plan notes payable assumed (868.1) Trade payables (39.6) Operating lease liabilities (283.9) Other liabilities and deferred revenue (311.3) Total net assets acquired and liabilities assumed $ 1,169.5 The purchase price allocations for the acquisitions from the third quarter of 2023 through the second quarter of 2024 are preliminary, and we have not obtained and evaluated all of the detailed information necessary to finalize the opening balance sheet amounts in all respects. We recorded the purchase price allocations based upon information that is currently available and recorded unallocated items as a component of other non-current assets in the Consolidated Balance Sheets. We expect all of the goodwill related to North American acquisitions completed in 2023 and 2024 to be deductible for US federal income tax purposes. Due to local country laws, we do not expect goodwill related to UK acquisitions completed in 2023 and 2024 to be deductible for UK income tax purposes. In the three and six-month periods ended June 30, 2024, we recorded $1.8 million and $9.5 million in acquisition-related expenses as a component of selling, general and administrative expense. Comparatively, we recorded $4.5 million and $5.7 million and of acquisition-related expenses in the same periods of 2023. The following unaudited pro forma summary presents consolidated information as if all acquisitions in the three and six-month periods ended June 30, 2024 and 2023 had occurred on January 1, 2023: Three Months Ended June 30, Six Months Ended June 30, (in millions, except per share amounts) 2024 2023 2024 2023 Revenue $ 9,276.3 $ 9,496.4 $ 18,361.9 $ 17,753.0 Net income attributable to Lithia Motors, Inc. 218.4 324.6 391.1 572.2 Basic earnings per share attributable to Lithia Motors, Inc. 8.03 11.79 14.29 20.80 Diluted earnings per share attributable to Lithia Motors, Inc. 8.02 11.77 14.27 20.76 These amounts have been calculated by applying our accounting policies and estimates.

Earnings Per Share [Abstract]
EARNINGS PER SHARE	EARNINGS PER SHARE We calculate basic earnings per share (EPS) by dividing net income attributable to Lithia Motors, Inc. by the weighted average number of common shares outstanding for the period, including vested RSU awards. Diluted EPS is calculated by dividing net income attributable to Lithia Motors, Inc. by the weighted average number of shares outstanding, adjusted for the dilutive effect of unvested RSU awards and employee stock purchases. The following is a reconciliation of net income attributable to Lithia Motors, Inc. and weighted average shares used for our basic EPS and diluted EPS: Three Months Ended June 30, Six Months Ended June 30, (in millions, except per share amounts) 2024 2023 2024 2023 Net income attributable to Lithia Motors, Inc. and applicable to common stockholders $ 214.2 $ 297.2 $ 376.7 $ 525.9 Weighted average common shares outstanding – basic 27.2 27.5 27.4 27.5 Effect of employee stock purchases and restricted stock units on weighted average common shares outstanding — 0.1 — 0.1 Weighted average common shares outstanding – diluted 27.2 27.6 27.4 27.6 Basic earnings per share attributable to Lithia Motors, Inc. $ 7.88 $ 10.79 $ 13.77 $ 19.11 Diluted earnings per share attributable to Lithia Motors, Inc. $ 7.87 $ 10.78 $ 13.75 $ 19.08 The effect of antidilutive securities on common stock was evaluated for the three and six-month periods ended June 30, 2024 and 2023 and was determined to be immaterial.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation These condensed Consolidated Financial Statements contain unaudited information as of June 30, 2024, and for the three and six months ended June 30, 2024 and 2023. The unaudited interim financial statements have been prepared pursuant to the rules and regulations for reporting on Form 10-Q. Accordingly, certain disclosures required by accounting principles generally accepted in the United States of America for annual financial statements are not included herein. In management’s opinion, these unaudited financial statements reflect all adjustments (which include only normal recurring adjustments) necessary for a fair presentation of the information when read in conjunction with our 2023 audited Consolidated Financial Statements and the related notes thereto. The financial information as of December 31, 2023, is derived from our Annual Report on Form 10-K filed with the Securities and Exchange Commission on February 23, 2024. The results of operations for the interim periods presented are not necessarily indicative of the results to be expected for the full year.
Reclassifications	Reclassifications Certain reclassifications of amounts previously reported have been made to the accompanying Consolidated Financial Statements to maintain consistency and comparability between periods presented. Within our financing operations income, we disaggregated our “lease income” out of our previously reported “interest, fee, and lease income” to be its own separately presented line item.
Commitments and Contingencies	Contract Liabilities We are the obligor on our lifetime oil and at home valet contracts. Revenue is allocated to these performance obligations and is recognized over time as services are provided to the customer. The amount of revenue recognized is calculated, net of cancellations, using an input method, which most closely depicts performance of the contracts. Our contract liability balances were $394.4 million and $317.0 million as of June 30, 2024, and December 31, 2023, respectively; and we recognized $18.2 million and $36.5 million of revenue in the three and six months ended June 30, 2024 related to our contract liability balance at December 31, 2023. Our contract liability balance is included in accrued liabilities and deferred revenue. Leases We lease certain dealerships, office space, land and equipment. Leases with an initial term of 12 months or less are not recorded on the balance sheet. We recognize lease expense for these leases on a straight-line basis over the lease term. We have elected not to bifurcate lease and non-lease components related to leases of real property. Most leases include one or more options to renew, with renewal terms that can extend the lease term from one Certain of our lease agreements include rental payments based on a percentage of retail sales over contractual levels and others include rental payments adjusted periodically for inflation. Our lease agreements do not contain any material residual value guarantees or material restrictive covenants. Our finance lease liabilities are included in long-term debt, with the current portion included in current maturities of long-term debt. The related assets are included in property, plant and equipment, net of accumulated amortization. We rent or sublease certain real estate to third parties.
Fair Value Measurements	Factors used in determining the fair value of our financial assets and liabilities are summarized into three broad categories: • Level 1 - quoted prices in active markets for identical securities; • Level 2 - other significant observable inputs, including quoted prices for similar securities, interest rates, prepayment spreads, credit risk; and • Level 3 - significant unobservable inputs, including our own assumptions in determining fair value. We determined the carrying value of cash equivalents, accounts receivable, trade payables, accrued liabilities, finance receivables, and short-term borrowings approximate their fair values because of the nature of their terms and current market rates of these instruments. We believe the carrying value of our variable rate debt approximates fair value. We have investments consisting of equity securities, available for sale debt securities, and equity method investments. We calculated the estimated fair value of the equity securities, equity method investments, and U.S. Treasury debt securities using quoted market prices (Level 1). The fair value of corporate and municipal debt securities are measured using observable Level 2 market expectations at each measurement date. See Note 6 – Investments. We have fixed rate debt primarily consisting of amounts outstanding under our senior notes, non-recourse notes payable, and real estate mortgages. We calculated the estimated fair value of the senior notes using quoted prices for the identical liability (Level 1). The fair value of non-recourse notes payable are measured using observable Level 2 market expectations at each measurement date. The calculated estimated fair values of the fixed rate real estate mortgages and finance lease liabilities use a discounted cash flow methodology with estimated current interest rates based on a similar risk profile and duration (Level 2). The fixed cash flows are discounted and summed to compute the fair value of the debt. We have derivative instruments consisting of an offsetting set of interest rate caps. The fair value of derivative assets and liabilities are measured using observable Level 2 market expectations at each measurement date and is recorded as other current assets, current liabilities and other long-term liabilities in the Consolidated Balance Sheets. Nonfinancial assets such as goodwill, franchise value, or other long-lived assets are measured and recorded at fair value during a business combination or when there is an indicator of impairment. We evaluate our goodwill and franchise value using a qualitative assessment process. If the qualitative factors determine that it is more likely than not that the carrying value exceeds the fair value, we would further evaluate for potential impairment using a quantitative assessment. The quantitative assessment estimates fair values using unobservable (Level 3) inputs by discounting expected future cash flows of the store for franchise value, or reporting unit for goodwill. The forecasted cash flows contain inherent uncertainties, including significant estimates and assumptions related to growth rates, margins, working capital requirements, and cost of capital, for which we utilize certain market participant-based assumptions we believe to be reasonable. We estimate the value of other long-lived assets that are recorded at fair value on a non-recurring basis on a market valuation approach. We use prices and other relevant information generated primarily by recent market transactions involving similar or comparable assets, as well as our historical experience in divestitures, acquisitions and real estate transactions. Additionally, we may use a cost valuation approach to value long-lived assets when a market valuation approach is unavailable. Under this approach, we determine the cost to replace the service capacity of an asset, adjusted for physical and economic obsolescence. When available, we use valuation inputs from independent valuation experts, such as real estate appraisers and brokers, to corroborate our estimates of fair value. Real estate appraisers’ and brokers’ valuations are typically developed using one or more valuation techniques including market, income and replacement cost approaches. Because these valuations contain unobservable inputs, we classified the measurement of fair value of long-lived assets as Level 3.
Recent Accounting Pronouncements	In November 2023, the Financial Accounting Standards Board (FASB) issued an accounting standards update (ASU) 2023-07 related to improvements to reportable segment disclosures. The amendments in this update require additional disclosure of significant expenses related to our reportable segments, additional segment disclosures on an interim basis, and qualitative disclosures regarding the decision making process for segment resources. The amendments in this update are effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024. We have adopted this pronouncement and plan to make the necessary updates to our segment disclosures for the year ending December 31, 2024, and, aside from these disclosure changes, we do not expect the amendments to have a material effect on our financial statements. In December 2023, the FASB issued ASU 2023-09 related to improvements to income tax disclosures. The amendments in this update require enhanced jurisdictional and other disaggregated disclosures for the effective tax rate reconciliation and income taxes paid. The amendments in this update are effective for fiscal years beginning after December 15, 2024. We plan to adopt this pronouncement and make the necessary updates to our disclosures for the year ending December 31, 2025, and, aside from these disclosure changes, we do not expect the amendments to have a material effect on our financial statements.
