RECONCILIATION OF NON-GAAP METRICS Net Income (Loss) to Adjusted EBITDA IN THOUSANDS Net Income (Loss) Interest and Other (Income) Expense Income Tax (Benefit) Expense Depreciation and Amortization Restructuring, Impairment and Related Charges, Net Change in Fair Value of Warrant Liabilities Stock-based Compensation Expense Adjusted EBITDA Q1 2023 ($15,025) (5,647) 3,668 13,743 5,535 515 3,916 $6,705 Q1 2022 $15,866 684 2,030 7,147 (31,686) ($5,959) Adjusted EBITDA We define Adjusted EBITDA as consolidated Net income (loss) excluding interest and other income (expense), income tax (expense) benefit, and depreciation and amortization, adjusted to exclude (i) restructuring, impairment and related charges, net; (ii) changes in fair value of warrant liabilities; (iii) stock-based compensation expense; (iv) when applicable, the net gain or loss from asset disposals; and (v) when applicable certain other unusual items. We present Adjusted EBITDA because we consider it to be an important supplemental measure of our performance and believe it is frequently used by securities analysts, investors, and other interested parties in the evaluation of companies in our industry. By providing this non-GAAP financial measure, together with a reconciliation to net income (loss), which is the most directly comparable GAAP measure, we believe we are enhancing investors' understanding of our business and our results of operations, as well as assisting investors in evaluating how well we are executing our strategic initiatives. However, Adjusted EBITDA has limitations as an analytical tool, and should not be considered in isolation, or as an alternative to, a substitute for net income (loss) or other financial statement data presented in our Consolidated Financial Statements as indicators of financial performance. Hagerty's Adjusted EBITDA may be determined or calculated differently than similarly titled measures of other companies in our industry, which could reduce the usefulness of this non-GAAP financial measure when comparing our performance to that of other companies.
