You never use Equity Value / EBITDA, but are there any cases where you might use Equity Value / Revenue?

It’s very rare to see this, but sometimes large financial institutions with big cash balances have negative Enterprise Values – so you might use Equity Value / Revenue instead. 

You might see Equity Value / Revenue if you’ve listed a set of financial institutions and non-financial institutions on a slide, you’re showing Revenue multiples for the nonfinancial institutions, and you want to show something similar for the financial institutions

Note, however, that in most cases you would be using other multiples such as P/E and P/BV with banks anyway.
