Precedent Transactions
A relative valuation method using the multiples paid in comparable historical M&A deals. Typically produces higher implied values than trading comps because it includes a control premium.

Build a transaction set, adjust for what makes each deal different, and say why it usually reads high.
Where it comes up. An MD preparing for a board meeting asks what a strategic buyer would actually pay, and why that sits above where the sector trades today.
Select on the deal, not just the company
Similar business, but also a similar situation: same rough size, comparable buyer type, and a process that was competitive rather than a rescue. A distressed sale and a contested auction for the same asset produce different multiples and belong in different tables.
Use the multiple at announcement
Take enterprise value at the announced price against the target’s last twelve months of EBITDA as disclosed at the time. Not today’s figures, and not the restated ones. The multiple is a record of what someone paid on a date, and mixing vintages destroys it.
Expect it to read above trading comps
Transaction multiples include a control premium, because the buyer acquires the ability to direct the business, and often a share of expected synergies. Trading comps price a minority stake with neither. That is the mechanism behind "precedents are usually highest", and it is the mechanism rather than the rule that gets asked about.
Discount old deals honestly
A multiple from a different rate environment or a different credit market is not directly comparable. Say how far back the set goes and treat anything from a very different cycle as context rather than evidence.
Worked through
A target with $120m LTM EBITDA. Trading comps median 8.5x; precedent set median 10.5x.
- Value on trading comps
- 8.5 × $120m = $1,020m
- Value on precedents
- 10.5 × $120m = $1,260m
- Implied control premium
- $240m, about 24%
The 2.0 turn gap is what a buyer is paying for control and expected synergies. If your precedent set came in BELOW trading comps, that is a finding worth explaining rather than a mistake: it usually means the market has re-rated the sector since those deals were struck.

That the financing environment was completely different. Deal multiples in a period of very cheap debt reflect what a buyer could borrow at, not just what the asset was worth. Carrying those multiples into a higher-rate market overstates value, and a defensible analysis either restricts the set to a comparable environment or states the vintage prominently and treats the older deals as context.

Why Precedent Transactions matters in interviews
Precedent transactions are the M&A banker's valuation anchor, and interviewers use them to test whether you understand that a deal price is a negotiated outcome, not a market observation. Knowing why they run high, and when they are stale — is the substance of the question.
How it works in practice
You identify historical acquisitions of similar companies, calculate the multiple paid on the target's metrics at announcement, and apply that range to your own target. Transaction value uses the price actually paid for the whole business, including assumed debt.
Precedent multiples typically exceed trading comps because they embed a control premium and, often, the acquirer's expected synergies. Both are reasons a strategic buyer will pay more than the public market.
Recency matters enormously. Deals struck in a different credit or rate environment tell you little about today's clearing price, so practitioners usually limit the set to the last three to five years and flag the market conditions of each.
What candidates get wrong
- Ignoring deal context — a distressed sale, a hostile situation and a competitive auction produce very different multiples for identical assets.
- Using the current share price rather than the announcement-date price when calculating the multiple paid.
- Failing to note whether the consideration was cash or stock, which affects both the premium paid and how the multiple should be read.
Precedent Transactions: frequently asked questions
How far back should a precedent transactions analysis go?
Usually three to five years. Older deals were struck under different interest rate, credit and sector conditions, so their multiples are poor evidence of what a buyer would pay today. If you must reach further back for a thin sector, flag the market environment explicitly.
Why are precedent transaction multiples higher than trading multiples?
Two reasons: the control premium an acquirer pays to own and direct the entire business, and the synergies a strategic buyer expects to realise, part of which typically gets shared with the seller in a competitive process.
