RECONCILIATION OF RETURN ON INVESTED CAPITAL Return on invested capital ("ROIC") is calculated by dividing Adjusted EBITA, net of tax (a non-GAAP measure) by average invested capital. Adjusted EBITA, net of tax, is calculated as Adjusted EBITDA (a non-GAAP measure), less stock-based compensation expense, less depreciation expense, less income taxes based on a tax rate that has been adjusted to exclude the impact of certain non-recurring and non-operating items that impacted income taxes calculated in accordance with GAAP. Average invested capital is the average of invested capital at the beginning of the applicable fiscal year and invested capital at the end of the applicable fiscal year. Invested capital is equal to (1) total assets, less cash and cash equivalents and assets of discontinued operations, minus (2) total current liabilities less current maturities of long-term debt and short-term debt, current portion of operating lease liabilities, and current liabilities of discontinued operations. 2022 QUANTA 2015 Adjusted EBITDA (a non-GAAP measure) $ 525,804 $ 1,684,938 Less: Depreciation Less: Stock-based compensation Adjusted EBITA (162,845) (290,647) (36,939) (105,600) 326,020 1,288,691 Income tax provision based on adjusted tax rate (122,844) (323,075) $ 203,176 $ 965,616 Adjusted EBITA, net of tax Total Assets (GAAP as reported) Less: Cash and cash equivalents Less: Current liabilities Plus: Current maturities of long-term debt and short-term debt Plus: Current portion of operating lease liabilities Plus: Current liabilities of discontinued operations Invested capital Prior year invested capital Average Invested Capital Return on Invested Capital (ROIC) $ 5,213,543 (128,771) (1,203,744) 7,067 $ 13,464,337 (428,505) (3,406,194) 37,495 74,052 15,313 3,903,408 4,233,975 9,741,185 9,568,549 $ 4,068,692 $ 9,654,867 5.0 % 10.0 % Page 54
