Obviously, you would rather get more data, like balance sheet. Perhaps the company has no debt, though, in which case you wouldn't have to deal with interest expenses.

It's also true that many private equity types just look at EBITDA multiples, so that's something you can do in a pinch... use comparable public companies, figure out the EBITDA multiple, and then come to some conclusion about how much of a discount you want to add in for the fact that private companies are liquid.

Obviously, when doing valuation, it's good to use several techniques and see what the range of values are. That helps prevent any one assumption from taking you far afield.
