What it means
Every valuation method needs an anchor, and a comparable transaction anchors the answer in what a real buyer actually paid for a similar business. Rather than forecasting cash flows decades into the future, you look at completed acquisitions in the same sector and of roughly the same size, then see where the price settled.
If a buyer paid nine times profit for a business like yours last year, that is genuine evidence of what yours might fetch. The word comparable is doing a lot of work in that sentence.
A deal is only a useful reference if the target was similar in industry, size, growth rate, margin profile and geography, and if it closed recently enough that market conditions have not moved on. A retail chain sold at the peak of a boom tells you very little about a retail chain sold into a downturn.
In practice an analyst builds a table of five to fifteen deals, calculates the multiple implied by each one, then takes the median rather than the average so a single strange outlier does not distort the answer. The multiple is usually enterprise value divided by EBITDA (earnings before interest, tax, depreciation and amortisation), because that measure ignores how each company happened to be financed.
Revenue and earnings multiples appear too, depending on what the sector treats as normal. Values produced this way tend to sit above the values implied by quoted share prices, because an acquirer pays a control premium for the right to run the business and to change it.
That premium is real information rather than an error, but it means transaction comparables and trading comparables answer slightly different questions. Bankers usually present both and let the range speak for itself.
The main practical difficulty is data quality. Private deal terms are often undisclosed, headline prices can hide earn-outs and assumed debt that change the true consideration, and the profit figure quoted may have been adjusted by the seller in ways that flatter it.
Careful analysts read the footnotes before trusting any multiple they did not calculate themselves.
In practice
Real-world examples.
Example
A family-owned bakery group is approached by a private equity buyer. Its adviser pulls together four bakery acquisitions completed in the previous two years, finds a median of 7.5 times EBITDA, and uses that as the opening anchor in negotiation rather than accepting the buyer's first offer of 5 times.
Example
A software company preparing for sale reviews recent deals in subscription analytics and notices that buyers paid between 4 and 6 times annual recurring revenue. Management uses the range to set a realistic internal target and to decide that another year of growth would be worth more than selling immediately.
Example
A hospital group's finance director is asked whether a $40,000,000 offer for its diagnostics division is fair. Comparable transactions in outpatient diagnostics cleared at around 11 times EBITDA, and the division earns $4,500,000, implying roughly $49,500,000, so the board pushes back on price.
Formula
Calculation
Implied enterprise value = multiple paid in the comparable deal x your company's matching financial metric.
Suppose a rival distribution business was acquired last year for an enterprise value of $180,000,000 while generating EBITDA of $20,000,000. The multiple paid was $180,000,000 / $20,000,000 = 9.0 times EBITDA.
Your company generates EBITDA of $12,000,000. Applying the same multiple gives an implied enterprise value of 9.0 x $12,000,000 = $108,000,000. If your company also carries net debt of $18,000,000, the implied value of the equity is $108,000,000 - $18,000,000 = $90,000,000.Case study
Seen in the real world.
In this illustrative and entirely fictional example, Harrowgate Precision Tooling received an unsolicited offer of $54,000,000 from a listed engineering group. The founders had no reference point beyond the fact that the number sounded large, so their adviser assembled six precedent transactions in specialist tooling completed within the previous thirty months.
Stripping out one deal that included a large property portfolio, the remaining five implied a median of 8.2 times EBITDA. Harrowgate's normalised EBITDA was $8,000,000, pointing to an enterprise value near $65,600,000 before any control premium argument. The gap between that figure and the offer gave the founders something concrete to negotiate against.
The eventual agreement settled at $62,000,000 plus a modest earn-out linked to retaining two key customers. The founders later said the most valuable part of the process was not the final number but understanding why the first offer had been low.
Watch out
Common mistakes.
- Treating the average multiple as the answer when one distressed or strategic deal has dragged the whole set away from the middle.
- Comparing an enterprise value multiple from a precedent deal against your own equity value, which double counts or ignores debt entirely.
- Using deals from four or five years ago without adjusting for how much interest rates, sector sentiment and buyer appetite have shifted since.
Questions
People also ask.
How many comparable transactions do you need?
Five to fifteen is typical; fewer than three makes the median meaningless, and more than twenty usually means the screen has become too loose.
Why do transaction multiples exceed trading multiples?
Because acquirers pay a control premium for the ability to direct the business, replace management and capture cost savings.
Can comparable transactions be used for a small private company?
Yes, though disclosed deal data thins out quickly at the smaller end, so the results should be treated as a sanity check rather than a precise valuation.
