Q: How is EV/FCF different from EV/EBITDA?
A: EBITDA adds back depreciation and amortization on the premise that they are non-cash charges, but for capital-intensive businesses, depreciation approximates the real ongoing cost of maintaining the asset base. Free cash flow subtracts actual capital expenditures instead of ignoring them, so EV/FCF reflects the cash left over after that spending has already happened. A large gap between a company's EV/EBITDA and EV/FCF multiples — EV/FCF being meaningfully higher — is a signal of high capital intensity relative to reported earnings.
