If a company doesn’t provide this metric (there’s no legal requirement to do so), you find it by looking at the firm’s financial statements. Look for the earnings, tax, and interest figures on the income statement; the amortization is normally found in the notes to operating profit or on the cash flow statement. A shortcut to calculating EBITA is to start with operating profit, also called earnings before interest and taxes (EBIT), then add back amortization.
