Private Equity: What the Firms Do, and Where the Returns Actually Come From

The interesting questions are what happens in between, where the return comes from, and — the question that determines everything for a reader — whether the returns that make the industry famous are available to anyone who is not already an institution.

What the firms actually do

The structure first, because it explains the behaviour. A firm raises a fund from institutional investors — pensions, endowments, insurers, sovereign funds — who commit capital for around ten years on the terms the fee article established. The firm then buys controlling stakes in companies, works on them, and exits by sale or listing. Control is the defining feature and the source of most of what follows: unlike a shareholder in a listed company, a buyout owner can replace management, change strategy, restructure the balance sheet, and act without quarterly scrutiny — which is a genuine advantage that public-market investors do not have and cannot replicate. Where the return comes from — three sources, and the mix matters enormously. Operational improvement: raising revenue, cutting costs, professionalising management, consolidating acquisitions. This is the source the industry emphasises and the one that represents genuine economic value creation — a company genuinely worth more than before. Multiple expansion: selling at a higher valuation multiple than was paid. This can reflect a genuinely improved business, and it can also reflect market conditions between purchase and sale — which means part of the return may be the market rather than the manager. And leverage: the debt used to buy the company, which the next article covers in full. The honest position on the mix is that it is contested and varies by fund, period, and strategy — researchers have attributed substantial portions to each of the three, and a reader should be sceptical of any firm claiming its returns are purely operational, and equally sceptical of any critic claiming they are purely leverage. Two further mechanics worth knowing. Dry powder: committed but uncalled capital, which the industry holds in large amounts and which affects competition for deals — more capital chasing the same companies raises purchase prices, which lowers future returns arithmetically rather than as a matter of opinion. And continuation vehicles, where a firm sells an asset to a fund it also manages, which has become common and raises a valuation question a reader should notice: the seller and the buyer share a manager.

Dispersion, and the access problem

Here is the fact that matters more than any average return figure: the dispersion between the best and worst funds in this industry is enormous, and far wider than in public equity funds. A top-quartile fund and a bottom-quartile fund from the same vintage year can differ by many percentage points annually — which means an average private-equity return describes an outcome few investors actually receive, and the entire question is manager selection. Three consequences follow, and they are unforgiving. Access to the best managers is rationed rather than purchased. The firms with the strongest records are frequently oversubscribed and allocate to long-standing institutional relationships — so a new investor with money is not thereby an investor with access, and the funds accepting unsolicited retail-adjacent capital are, by selection, not the ones turning capital away. Past performance is a weak predictor even here. Persistence in private-equity returns is genuinely debated, with evidence that it has weakened as the industry has grown — so selecting on track record is less reliable than it appears. And the published averages are compromised in the three ways the fee article set out: IRR timing sensitivity, appraisal valuation of unrealised holdings, and survivorship in voluntary databases. Now the comparison a reader actually needs. The relevant question is not whether private equity has outperformed public equity on average, but whether the version available to this reader, after every fee layer, net of the access penalty, and adjusted for the leverage embedded in the strategy, outperforms a low-cost public equity fund. The arithmetic there is unfriendly: a fund returning 15% gross delivers 12.1% net, or 11.3% through a feeder — and since buyout returns are partly leveraged equity returns, the honest public-market comparison is not an unleveraged index but a leveraged one, which narrows the gap considerably. What this article will not do is claim the industry produces nothing. Control, patient capital, and operational focus are real advantages; some firms demonstrably improve the companies they buy; and providing capital and governance to businesses too small or complex for public markets is a genuine economic function. What it will say is that the average is not the offer, the best is not accessible, and the comparison should be net of everything against a leveraged benchmark.
