Reconciliation of Non-GAAP Measures APPENDIX EBITDA Three Months Ended March 31, ($ in thousands) 2024 2023 Net income $ 36,545 $ 7,259 Interest expense, net 9,321 10,394 Provision for income taxes 11,745 2,390 Depreciation and amortization 32,689 32,499 EBITDA $ 90,300 $ 52,542 FREE CASH FLOW Three Months Ended March 31, ($ in thousands) 2024 2023 Net cash flows (used in) provided by operating activities $ (7,654) $ 74,676 Capital expenditures (8,608) (17,159) Free cash flow $ (16,262) $ 57,517 12 EBITDA and free cash flow are non-GAAP performance measures included to illustrate and improve comparability of the Company's results from period to period. EBITDA is defined as net income (loss) before interest expense, provision (benefit) for income taxes, depreciation and amortization expense. Free cash flow is defined as net cash flows provided by operating activities minus capital expenditures. The Company considers these non-GAAP measures in evaluating and managing the Company's operations and believes that discussion of results adjusted for these items is meaningful to investors because they provide a useful analysis of ongoing underlying trends. The adjusted measures are not in accordance with, nor are they a substitute for, GAAP measures, and they may not be comparable to similarly titled measures used by other companies.
