(2) For the relevant fiscal year, represents the cumulative TSR (the “Peer Group TSR”) of the S&P 500 Retailing Index.

(3) Adjusted EBITDA is a non-GAAP measure. We define “EBITDA” as net income before other interest expense, net (excluding floor plan interest expense), provision for income tax expense and depreciation and amortization. We define “Adjusted EBITDA” as EBITDA further adjusted for the impact of certain noncash and other items that we do not consider in our evaluation of ongoing operating performance. These items include, among other things, loss and expense on debt restructure, long-lived asset impairment, lease termination costs, gains and losses on sale or disposal of assets, net, equity-based compensation, Tax Receivable Agreement liability adjustment, restructuring costs related to the 2019 Strategic Shift, and other unusual or one-time items. For a reconciliation of Adjusted EBITDA to net income, see “Non-GAAP Financial Measures” in Item 7 of Part II of our Annual Report on Form 10-K for the fiscal year ended December 31, 2022. We selected Adjusted EBITDA as the Company-Selected Measure due to it being an important financial performance measure that helps link compensation actually paid to the Company’s NEOs to the

Company’s performance for the most recently completed fiscal year. Specifically, Adjusted EBITDA is used to evaluate performance under the Company’s annual performance-based cash incentive program.

The graphs below compare the compensation actually paid to our PEO and the average of the compensation actually paid to our remaining NEOs, with (i) our cumulative TSR, as well as the relationship between our TSR and the Peer Group TSR, (ii) our net income, and (iii) our Adjusted EBITDA, in each case, for the fiscal years ended December 31, 2020, 2021 and 2022.

TSR amounts reported in the graph assume an initial fixed investment of $100, and that all dividends, if any, were reinvested.
