I have a set of precedent transactions but I’m missing information like EBITDA for a lot of the companies – how can I find it if it’s not available via public sources?

1. Search online and see if you can find press releases or articles in the financial press with these numbers.
2. Failing that, look in equity research for the buyer around the time of the transaction and see if any of the analysts estimate the seller’s numbers.
3. Also look on online sources like Capital IQ and Factset and see if any of them disclose numbers or give estimates.
