RECONCILIATION OF NET LEVERAGE* -Earnings before interest, taxes, depreciation and amortization (“EBITDA”), Pro-Forma Adjusted EBITDA, and Net Debt to Pro-Forma Adjusted EBITDA are non-GAAP financial measures. In addition to reporting financial results in accordance with accounting principles generally accepted in the United States, we provide non-GAAP operating results adjusted for certain items and other one-time items. -We adjust for the items listed above in all periods presented, unless the impact is clearly immaterial to our financial statements. -We utilize the adjusted results to review our ongoing operations without the effect of these adjustments and for comparison to budgeted operating results. We believe the adjusted results are useful to investors because they help them compare our results to previous periods and provide important insights into underlying trends in the business and how management oversees our business operations on a day-to-day basis. -We calculate free cash flow by subtracting cash paid for purchases of property, plant and equipment from cash flow from operations. - Figures may not sum due to rounding. * As defined by credit agreement which includes debt and cash balances RECONCILIATION OF NET INCOME TO EBITDA TO PRO-FORMA ADJUSTED EBITDA* RECONCILIATION OF FREE CASH FLOW FOR THE TRAILING TWELVE MONTHS $ 172 68 53 139 $ 432 $ 3,885 20 11 $ 462 Q2’23 TTM ($ in millions) Total debt outstanding @ 7/2/2023 $ 1,236.9 Less: cash on hand @ 7/5/2023 (33.9) Net debt @ 7/5/2023 $ 1,203.0 Pro-Forma Adjusted EBITDA $ 462.4 Net debt to Pro-Forma Adjusted EBITDA 2.6x Cash Flow from Operations $ 516 Less: Capital Expenditures (72) Free Cash Flow $ 444 11.1% ($ in millions) 19 Use of Non-GAAP Financial Measures This presentation contains non-GAAP financial measures.
