Why does the same business trade higher when it is bigger?
Because fund size dictates cheque size, and cheque size dictates which assets a buyer is allowed to consider. A fund with billions to deploy cannot write four million dollar equity cheques without breaking its own portfolio construction, so it sets a floor and everything below the floor is invisible to it regardless of quality.
Capital has concentrated into exactly those funds. Thirteen funds raising five billion dollars or more captured 49 percent of all US private equity capital raised in 2025, and large buyout funds now manage 46 percent of global private equity assets, up from 35 percent in 2015 (iCapital, Scale Advantages in Private Equity Buyout, February 2026, measuring 2025 and labelled as such). The top ten firms in the 2026 industry ranking raised 854.6 billion dollars between them, about a quarter of the entire ranking (PEI 300, June 2026).
So crossing a size threshold does something no operational improvement can do on its own: it adds bidders. A business that becomes reachable by a new class of fund is not a better business the following morning. It is a more contested one, and contest is what sets price.
The folk explanation, that bigger companies are simply better run and less risky, is partly true and is not the mechanism. Both effects point the same way, which is why the premium is stable enough to plan against.
How big is the step?
Roughly four turns across the published ladder. Transactions between ten and twenty-five million dollars of enterprise value averaged 5.9 times EBITDA while transactions between one hundred and two hundred and fifty million averaged 10.0 times (GF Data, published 27 January 2026, covering the first nine months of 2025). That table is the only public size-band series that exists, and no 2026 print has been published as at August 2026, so it is a labelled baseline rather than a current quote.
A second cut of the same data measures a different pair of bands: large platforms between one hundred and five hundred million dollars of enterprise value averaged 9.8 times against 7.0 times for platforms below one hundred million, a spread of 2.8 turns, up from 2.4 turns in the first half of 2025 and above the long-run average of 2.6 turns (GF Data, January 2026). The two spreads are not alternative estimates of one quantity and should not be blended.
The current-vintage evidence is thinner but points the same way. Transactions above two hundred and fifty million dollars averaged 12.2 times enterprise value to EBITDA in the first quarter of 2026 (Capstone Partners, Capital Markets Update, 4 June 2026), and global trailing enterprise value to EBITDA held near 10.7 times with North American large and mega-cap transactions reaching 11 to 13 times (Valuation Research Corporation, citing PitchBook, as at the first quarter of 2026).
Those large-cap numbers are the ones owners see quoted in the press, and they sit several turns above middle-market reality. An owner benchmarking a business against a figure drawn from transactions ten times its size is benchmarking against a different market.
| Enterprise value band | Average EV to EBITDA | Total leverage available |
|---|---|---|
| 10 to 25 million dollars | 5.9 times | 2.50 to 3.25 times for issuers below ten million dollars of EBITDA |
| Platforms below 100 million dollars | 7.0 times | 4.00 to 5.50 times for issuers above ten million dollars of EBITDA |
| 100 to 250 million dollars | 10.0 times | 5.00 to 6.50 times for issuers above twenty-five million dollars of EBITDA |
| Above 250 million dollars | 12.2 times in the first quarter of 2026 | Syndicated and large private credit markets, priced off a different curve |
“The threshold is not a valuation opinion, it is an arithmetic constraint inside somebody else's fund. That is why arguing quality does not move it and adding size does. A business that reaches the floor gets a longer buyer list, and the longer list is the entire re-rating.”
How much of the premium is financing rather than buyers?
A substantial part, and it is the half most sellers never see. A buyer's ability to pay is a function of what it can borrow, and borrowing capacity rises steeply with size in the same way multiples do.
The current bands make the point. Total debt for issuers below ten million dollars of EBITDA clears at 2.50 to 3.25 times, while issuers above twenty-five million clear at 5.00 to 6.50 times (SPP Capital Partners, Market At A Glance, July 2026). The smaller company's buyer must fund a much larger share of the price with equity, which is the most expensive money in the structure.
Pricing moves in the same direction. Non-bank unitranche costs SOFR plus 550 to 750 for a borrower below ten million dollars of EBITDA against SOFR plus 425 to 575 above twenty-five million, a gap of roughly 125 to 175 basis points at the same seniority (SPP Capital Partners, July 2026). More leverage, cheaper, against the same earnings quality.
Put the two together and the size premium stops looking mysterious. The larger business is bid by more buyers, each of whom can borrow more of the purchase price at a lower rate. Neither effect has anything to do with how well the smaller business is run.
Does buying scale actually work?
It can, and the arithmetic is why three-quarters of sponsor buyouts are add-ons rather than platforms (PitchBook, Q2 2026 US PE Breakdown, 6 July 2026). Acquiring businesses at the lower band's multiple and having them valued at the platform's multiple is the most reliable value creation mechanism available in this market.
The test of whether it works in a specific case is narrower than the strategy. Three things have to hold: the acquisitions must actually clear at the small-company multiple after transaction costs, the combined business must be genuinely one company rather than a holding structure, and the leverage used must leave headroom for the acquisitions still to come.
The evidence on the second condition is the sobering part. In one dataset of buy-and-build programmes, the cohort with two or more add-ons produced the lowest returns despite the fastest revenue growth (BCG and HHL Leipzig data, cited by CapitalPad, June 2026). Reaching the threshold and being valued at it are separate achievements, and the second requires the integration the first does not.
For an owner rather than a sponsor, there is a simpler version of the same question. If two years and a modest amount of debt would move a business from one band into the next, the published ladder says that is worth several turns of EBITDA. If it would take five years, three acquisitions and full leverage, the risk is being taken to capture a spread the market may not still be paying.
Which size band is worst positioned right now?
The middle of the middle. Lower middle market volume between ten and one hundred million dollars of enterprise value rose 45.8 percent year on year in the first quarter of 2026, and the upper middle market between two hundred and fifty and five hundred million took 39.9 percent of middle-market capital deployed against a twenty-year average of 31.5 percent. The core middle market between one hundred and two hundred and fifty million was described as comparatively more constrained, sitting between small self-funded acquisitions and large institutional must-own assets (Capstone Partners, Capital Markets Update, 4 June 2026).
That is a barbell, and a business in the middle of it faces the least favourable buyer list in the market: too large for self-funded and independent sponsor buyers to reach comfortably, too small to be a required asset for a large fund. Owners in that band should hear it plainly rather than discover it in month four of a process.
The remedy is not necessarily to grow. It is to build the buyer list from the classes that are actually active at that size, which currently means strategic acquirers, sponsor platforms doing add-ons, and family offices investing directly rather than funds seeking new platforms.
And there is a timing point underneath. Whether the size premium widens or narrows from here depends partly on financing conditions, which are not improving: three-month SOFR forwards price 4.04 percent at the end of 2027 against 3.76 percent in early August 2026 (Blue Gamma, 4 August 2026). A plan to grow into a higher multiple has to be robust to the possibility that leverage stays expensive for the whole of it.
