Precedent transactions answer a different question than trading comps: what have real acquirers actually paid to buy similar companies outright? Instead of looking at where peers trade day to day, you look at the multiples paid in completed M&A deals. It's the most concrete evidence you have of what a whole company changes hands for, because someone actually wrote the check.
The mechanics mirror trading comps. You assemble a set of past deals involving similar targets, compute the multiple paid in each (usually EV / EBITDA, off the target's metrics at announcement), and apply that range to your company. The difference is what the multiples embed.
The control premium
When an acquirer buys a company, it doesn't pay the trading price. It pays a premium over it, typically in the range of 20% to 40%. That premium buys two things: control (the right to run the business, replace management, redirect strategy) and synergies (cost cuts and revenue gains the buyer expects to capture). A minority shareholder buying 100 shares gets neither, which is why they pay less.
This is why precedent transactions almost always produce higher values than trading comps. Comps reflect a minority, no-control trading price; precedents reflect a full-control acquisition price with a premium baked in. So the two methods bracket the answer: comps set the floor of the range, precedents set the ceiling. If your precedents came in below your comps, something is wrong with one of the sets.

Frequently asked
- What are precedent transactions in valuation?
- Precedent transactions value a company off what real acquirers actually paid to buy similar businesses in past M&A deals. Instead of where peers trade day to day, you look at multiples paid in completed deals, usually EV/EBITDA off the target's metrics at announcement. It is the most concrete evidence of what a whole company changes hands for.
- What is the control premium and how big is it?
- The control premium is the amount an acquirer pays over the trading price to buy a company, typically 20% to 40%. It buys two things: control, meaning the right to run the business and replace management, and synergies, the cost cuts and revenue gains the buyer expects. A minority shareholder gets neither, which is why they pay less.
- Why does reaching back too far for deals hurt a precedent set?
- Transaction multiples are a snapshot of the market at the moment the deal was struck. A frothy-cycle acquisition from 2007 was priced in a very different credit and equity environment and tells you little about what a buyer would pay in a tighter market. Recency and comparable deal conditions matter as much as a comparable target.
