More Detailed Financial Analysis to Determine a Good PE Target?

Hello all,

I know there has been much talk about various criteria that makes companies good LBO candidates. But I was wondering if there are any more specific financial ratios beyond margins, growth, FCF generation, debt profile that one could look at to understand a private company better in terms of its attractiveness as a PE target.

Also, let's say a company already ticks all the typical LBO criteria - margins, growth, stable FCF, strong asset base, good market positioning / strong management - I am sure the decision to invest would never be taken just based on that. What other things would you look at?

Many thanks!
