What is the valuation overhang?
The gap between what sponsor-owned companies are carried at and what they would fetch if sold today. It exists because private assets are valued periodically by their owners under review, rather than continuously by a market, and because the population being valued was largely bought at higher prices than currently clear.
The composition of that population is the problem. A majority of assets in buyout portfolios, by both count and value, were acquired in 2021 or earlier, underwritten at or before peak pricing (Bain and Company, Private Equity Midyear Report 2026, 8 June 2026, on MSCI holdings data as at the fourth quarter of 2025). This is not a tail of stragglers. It is the median asset.
The inventory is not clearing. There were 13,509 US private equity backed companies as at 30 June 2026, up from 13,325 three months earlier, so the backlog grew through the first half of the year despite a strong prior exit year (PitchBook, Q2 2026 US PE Breakdown, 6 July 2026). Globally, 34 percent of portfolio companies had been held for more than five years as at 31 March 2026 (PwC, citing PitchBook data; note PwC's own two pages give the prior-year comparison as 25 percent and 28 percent respectively, so the direction is reliable and the increment is not).
For a business owner none of this is abstract. The sponsor-owned competitor down the road is carried at a number, and the price at which it eventually sells sets the comparable that a buyer will quote back to you.
Why do private marks move so slowly?
Because lowering one is a decision rather than an event, and the people making the decision have concrete reasons to make it gradually. A markdown reduces reported returns in the period it is taken, and reported returns are what a manager takes to market when raising the next fund.
The limited partner tolerance for the gap is measurable and narrow. More than half of limited partners lose confidence in a manager once a full exit prices more than 5 percent below the last carrying value (ILPA webcast polls, April 2026, published in Bain and Company, 8 June 2026). A manager holding an asset that would clear 20 percent below its mark is therefore choosing between a slow write-down and a fast loss of credibility.
The first hard evidence of movement arrived in 2026. Software valuations in private equity portfolios declined about 8 percent in the first quarter of 2026, with the United States at 8.9 percent and Europe at 4.2 percent (Bain and Company, 8 June 2026, on proprietary MSCI analysis, as at 31 March 2026). Against a public software move several times larger, a nine percent adjustment implies more to come rather than a completed correction.
There is an older reading that points the same way and should be labelled as older. Exits priced between 0.5 and 1.1 turns below held marks from 2022 through the third quarter of 2024, a reversal of a decade-long pattern in which they printed above (MSCI, May 2025, used here as labelled historical context).
“A public company reprices every morning whether anyone likes it or not. A private company reprices when a valuation committee decides it should, and the same committee is preparing to raise a fund. That is not dishonesty, it is a structure, and it is why the adjustment arrives as a series of small quarterly steps rather than a single day.”
Are private marks simply overstated?
Not on the realised evidence, and this is the correction that most commentary on the subject omits. More than 75 percent of buyout assets still exit above their next-to-final quarterly mark, broadly consistent with historical patterns (Bain and Company, 8 June 2026, on MSCI data covering global buyout exits from 2021 to 2025).
Read carefully, that finding is compatible with an overhang rather than contradicting it. Managers sell the assets that clear above their marks and hold the ones that do not, so the realised population is a selected sample. What it does establish is that the marks on the assets that transact are not systematically fictional.
Public markets are pricing a haircut on the unsold remainder. Listed business development companies traded at an average of 0.85 times net asset value, a 14.7 percent discount, with a median of 0.80 times and individual vehicles at 0.44 to 0.50 times (With Intelligence, as at 24 April 2026). That is a daily-marked opinion on where private credit valuations may be revised, and it is an opinion rather than a measurement.
The honest summary is that both claims are partly true. Marks are not fabricated, and they are stickier than the market they describe. The overhang lives in the difference between the assets that transact and the assets that do not.
| Reading | Figure | What it actually measures |
|---|---|---|
| Marks are moving | Software valuations in buyout portfolios down about 8 percent in the first quarter of 2026, United States 8.9 percent, Europe 4.2 percent | Carried valuations of held assets, adjusted by their owners under review, as at 31 March 2026 |
| Marks are not fictional | More than 75 percent of buyout assets exit above their next-to-final quarterly mark | Realised exits from 2021 to 2025, which is a selected sample of assets that could be sold |
| Exits printed below marks | Exits 0.5 to 1.1 turns below held marks from 2022 through the third quarter of 2024 | A labelled historical reading, reversing a decade-long pattern |
| Public markets disagree | Listed business development companies at an average 0.85 times net asset value, median 0.80 times, individual vehicles at 0.44 to 0.50 times | A daily-marked opinion on private credit valuations as at 24 April 2026, not a measurement of them |
How long does the unwind take?
Years, and the structural reason is that clearing requires transactions rather than opinions. Distributions as a share of net asset value now imply an approximately seven-year capital cycle for the buyout industry, well beyond historical norms and following four consecutive years of record-low distributions (Bain and Company, 8 June 2026, on MSCI data as at May 2026).
The cohort arithmetic is starker. Four years after investment, only 16.6 percent of the 2021 cohort had exited against 32.3 percent of the 2017 cohort, and extrapolating at recent annualised exit rates would leave roughly half the 2021 cohort unexited at the ten-year mark (PitchBook, 2026 US Private Equity Outlook, published 3 December 2025, as at 31 October 2025, extrapolated).
The forcing function is fund life rather than sentiment. Funds from 2020 and 2021 deployed at peak valuations on five to six year hold assumptions, which places their natural exit windows in 2025 to 2027, arriving exactly when bid-ask spreads are widest (Allianz Research, Private equity in transition, 20 February 2026, published before the second-quarter 2026 shock and labelled accordingly).
So the mechanism that finally moves the marks is a manager who needs a realisation more than it needs the mark. That is already visible: some sponsors are accepting lower exit valuations simply to generate the realised returns needed to raise their next vehicle (PwC, US Deals 2026 midyear outlook, 17 June 2026).
What does this mean for a seller now?
That the comparable a buyer quotes you may be stale in a direction that does not favour you, and that the competing supply is about to increase. Both points are actionable and neither is an argument for waiting.
On comparables, ask what the quoted transaction actually was. A sponsor-to-sponsor sale at a strong multiple two years ago tells you very little about today, and sponsor-to-sponsor volume has collapsed to the lowest quarterly mark in at least a decade (PitchBook, 6 July 2026). A buyer using old comparables in either direction should be asked to date them.
On supply, a backlog that is not clearing is a queue you may end up standing in. An owner who is prepared can choose the moment; an owner who begins preparing when the market improves arrives with everyone else. Exit preparation is generally advised to begin twelve to twenty-four months before a sale (EY, Global Private Equity Exit Readiness Study 2026, published 28 July 2026).
The one genuinely favourable reading in the current data belongs to well-run private businesses. Sponsors going down-market, holding longer and needing operating growth rather than multiple expansion are describing a preference for exactly the kind of company that has been run for cash rather than for a story. The overhang is a problem for assets bought at peak, not for businesses that were never priced that way.
