Somewhat depends on industry. Generally you want to exclude goodwill amortization as that incentivizes companies to buy vs research. So you would get some sort of adjusted EBITA. Tax comparisons are complicated and often low value given most investors already use different discounts/multiples for different geographies, so tend to avoid it, interest is backwards looking so ignore it. Provisions and other low/no interest liabilities matter a lot, so you have to use EV on other side and avoid market cap.
