Precedent Transaction Analysis

A public company's shares trade at 8x EBITDA. But when a similar company in the same industry was actually acquired last year, the buyer paid 12x EBITDA — a 50% premium to what the market was pricing the shares at beforehand. Trading comparables tell you what investors will pay for a minority slice of shares on an exchange; precedent transactions tell you what an acquirer will actually pay to own the whole company, control included.

Why it differs from trading comparables, and why that's the point

Trading comparables and precedent transactions ask two different questions. Trading comparables ask: what does the market pay for a minority stake, freely tradable, with no ability to change how the company is run? Precedent transactions ask: what did an acquirer pay to control 100% of the company, redirect its strategy, extract synergies, and remove it from the public market entirely?

The gap between the two — a control premium, typically in the 20–40% range historically, though it varies widely by deal — reflects the value of control itself: the ability to replace management, restructure operations, combine with the buyer's existing business, and capture synergies the standalone public company couldn't realize on its own.

Because of this, precedent transactions are the natural method when the valuation question is "what should a buyer pay to acquire this company," while trading comparables are the natural method when the question is "what is a minority share worth on the open market."

Worked example

A target company generates $50 million of EBITDA. Its public peer group trades at a median 8.0x EV/EBITDA. Three recent acquisitions of similar companies closed at 10.5x, 11.0x, and 13.5x EV/EBITDA, with a median of 11.0x.

1. Trading comps value: 50 \times 8.0 = \400$ million enterprise value — a minority-stake, no-control estimate.
2. Precedent transactions value: 50 \times 11.0 = \550$ million enterprise value — what recent buyers actually paid for control of similar companies.
3. Implied control premium: $(11.0 / 8.0) - 1 \approx 37.5\%$, in line with typical historical ranges.

An advisor pitching this company for sale would present both numbers, but would frame the precedent transaction range as the more relevant anchor for what a real buyer is likely to offer.

What this means in practice

Precedent transactions have real weaknesses that trading comparables don't share: deal terms and disclosed financials are often incomplete, deals age (a transaction from a very different market environment may not reflect current conditions), and each deal's premium reflects its own unique synergies and competitive dynamics rather than a clean market-wide number. Analysts typically restrict the sample to deals within the last 3–5 years and adjust for market conditions at the time.
