REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Stockholders of LKQ Corporation

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of LKQ Corporation and subsidiaries (the "Company") as of December 31, 2023 and 2022, the related consolidated statements of income, comprehensive income, stockholders' equity, and cash flows, for each of the three years in the period ended December 31, 2023, and the related notes (collectively referred to as the "financial statements"). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2023 and 2022, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2023, in conformity with accounting principles generally accepted in the United States of America.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company's internal control over financial reporting as of December 31, 2023, based on criteria established in Internal Control — Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission and our report dated February 22, 2024, expressed an unqualified opinion on the Company's internal control over financial reporting.

Basis for Opinion

These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on the Company's financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

Critical Audit Matters

The critical audit matters communicated below are matters arising from the current-period audit of the financial statements that were communicated or required to be communicated to the audit committee and that (1) relate to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the financial statements, taken as a whole, and we are not, by communicating the critical audit matters below, providing separate opinions on the critical audit matters or on the accounts or disclosures to which they relate.

Goodwill Impairment Assessment - Refer to Notes 2 and 10 to the financial statements.

Critical Audit Matter Description

The Company’s evaluation of goodwill for impairment involves the comparison of the fair value of each reporting unit to its carrying value. The Company determines the fair value of its reporting units using a discounted cash flow model and the market approach, which require management to make significant estimates and assumptions.

Auditing the estimates and assumptions that impacted the valuation of certain reporting units involved especially subjective judgment; specifically, the forecasts of future revenue and profit margins (“forecasts”), the selection of discount rates, and the determination of market multiples.

How the Critical Audit Matter Was Addressed in the Audit

Our audit procedures related to the forecasts, the selection of discount rates, and determination of market multiples included the following, among others:

•We tested the effectiveness of controls over the goodwill impairment assessments, including those over the forecasts and the selection of the discount rates and market multiples.

•We evaluated management’s ability to accurately forecast by comparing actual results to management’s historical forecasts.

•We evaluated the reasonableness of management’s forecasts by comparing the forecasts to (1) historical results, (2) internal communications to management and the Board of Directors, (3) analyst and industry reports of the Company and companies in its peer group, and (4) forecasts used in the preceding impairment assessments.

•With the assistance of our fair value specialists, we evaluated the discount rates, including (1) testing the underlying source information and the mathematical accuracy of the calculations, (2) developing a range of independent estimates and comparing those to the discount rates used by management, and (3) comparing the discount rates used by management to those used in the preceding impairment assessments.

•With the assistance of our fair value specialists, we evaluated the market multiples, including testing the underlying source information and mathematical accuracy of the calculations, and comparing the multiples selected by management to its guideline public companies and the multiples used in the preceding impairment assessments.

Business Combinations - Refer to Note 3 to the financial statements.

Critical Audit Matter Description

The Company completed the acquisition of Uni-Select Inc. for approximately $2.1 billion on August 1, 2023. The Company accounted for this acquisition using the acquisition method of accounting, under which the acquisition purchase price is allocated to the assets acquired, including purchased intangible assets, and liabilities assumed based on their respective fair values.

The purchase price allocation included customer and supplier relationship intangible assets of $669 million and trade name intangible assets of $17 million. The Company’s estimation of the value of the customer and supplier relationships and the trade names required management to make significant estimates and assumptions, including future expected cash flows including revenue growth assumptions from product sales and customer contracts, royalty rates, customer attrition rates and discount rates.

We identified the valuation of the customer and supplier relationship and trade name intangible assets for Uni-Select Inc. as a critical audit matter because of the significant estimates and assumptions management made to determine the fair value of these assets discussed above. This required a high degree of auditor judgment and an increased extent of effort, including the need to involve our fair value specialists, when performing audit procedures to evaluate management’s valuation methodologies and the reasonableness of management’s assumptions related to future expected cash flows and the selection of royalty rates, customer attrition rates and discount rates.

How the Critical Audit Matter Was Addressed in the Audit

Our audit procedures related to the fair value of the acquired intangible assets discussed above included the following, among others:

•We tested the effectiveness of controls over the purchase price allocation, including management’s controls over the appropriateness of the valuation methodology, forecast of future expected cash flows, and selection of the royalty rates, customer attrition rates and discount rates.

•We assessed the reasonableness of management’s forecast of future expected cash flows by comparing the projections to historical results and certain peer companies. We also evaluated whether the estimated future expected cash flows were consistent with evidence obtained in other areas of the audit.

•With the assistance of our internal fair value specialists, we evaluated the reasonableness of the valuation methodology, royalty rates, customer attrition rates and discount rates by:

◦Testing the mathematical accuracy of the calculations.

◦Testing the source information underlying the determination of the royalty, customer attrition and discount rates.

◦Developing ranges of independent estimates and comparing those to the rates selected by management.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Stockholders of LKQ Corporation

Opinion on Internal Control over Financial Reporting

We have audited the internal control over financial reporting of LKQ Corporation and subsidiaries (the “Company”) as of December 31, 2023, based on criteria established in Internal Control — Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2023, based on criteria established in Internal Control — Integrated Framework (2013) issued by COSO.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated financial statements as of and for the year ended December 31, 2023, of the Company and our report dated February 22, 2024, expressed an unqualified opinion on those financial statements.

As described in the Report of Management on Internal Control over Financial Reporting, management excluded from its assessment the internal control over financial reporting at Uni-Select Inc., which was acquired on August 1, 2023, and whose financial statements constitute 16% of total assets (inclusive of goodwill and acquired intangible assets) and 4% of revenue of the consolidated financial statement amounts as of and for the year ended December 31, 2023. Accordingly, our audit did not include the internal control over financial reporting at Uni-Select Inc.

Basis for Opinion

The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Report of Management on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

Definition and Limitations of Internal Control over Financial Reporting

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.
