28 US Ecology reports adjusted EBITDA, adjusted earnings per diluted share, pro forma Adjusted EBITDA, pro forma earnings per diluted per share and pro forma revenue results, which are non - GAAP financial measures, as a complement to results provided in accordance with generally accepted accounting principles in the United States (GAAP) and believes that such information provides analysts, stockholders, and other users information to better understand the Company’s operating performance . Because adjusted EBITDA, adjusted earnings per diluted share, pro forma Adjusted EBITDA , pro forma earnings per diluted per share and pro forma revenue are not measurements determined in accordance with GAAP and are thus susceptible to varying calculations they may not be comparable to similar measures used by other companies . Items excluded from adjusted EBITDA, adjusted earnings per diluted share, pro forma Adjusted EBITDA , pro forma earnings per diluted per share and pro forma revenue are significant components in understanding and assessing financial performance . Adjusted EBITDA, adjusted earnings per diluted share, pro forma Adjusted EBITDA , pro forma earnings per diluted per share and pro forma revenue should not be considered in isolation or as an alternative to, or substitute for, revenue, net income, cash flows generated by operations, investing or financing activities, or other financial statement data presented in the consolidated financial statements as indicators of financial performance or liquidity . Adjusted EBITDA , adjusted earnings per diluted share, pro forma Adjusted EBITDA , pro forma earnings per diluted per share and pro forma revenue have limitations as analytical tools and should not be considered in isolation or a substitute for analyzing our results as reported under GAAP . 28 Adjusted and Pro Forma EBITDA, EPS & Revenue

28

29 Adjusted EBITDA The Company defines adjusted EBITDA as net income before interest expense, interest income, income tax expense, depreciation, amortization, stock based compensation, accretion of closure and post - closure liabilities, foreign currency gain/loss and other income/expense, which are not considered part of usual business operations . Adjusted Earnings Per Diluted Share The Company defines adjusted earnings per diluted share as net income plus the after tax impact of non - cash, non - operational foreign currency gains or losses (“Foreign Currency Gain/Loss”) plus the after tax impact of business development costs divided by the number of diluted shares used in the earnings per share calculation . The Foreign Currency Gain/Loss excluded from the earnings per diluted share calculation are related to intercompany loans between our Canadian subsidiary and the U . S . parent which have been established as part of our tax and treasury management strategy . These intercompany loans are payable in Canadian dollars (“CAD”) requiring us to revalue the outstanding loan balance through our consolidated income statement based on the CAD/United States currency movements from period to period . We believe excluding the currency movements for these intercompany financial instruments provides meaningful information to investors regarding the operational and financial performance of the Company .
