[lemma]

A quick note (since I'm on my phone) until someone posts a better reply: ev/fcf is a financial ratio you can use to compare how much you are paying for various companies (idea being that similar companies should sell for roughly similar ratios). DCF takes all the cash a company will ever make and tells you how much you should pay for that now. Basically, there are a lot of ways to value a company and some methods are better suited for a given stage in a company's life than others (for example, many methods fall apart when a company has no earnings or has negative cash flows).
