KKR Balance-Sheet Bet Pays Off With $3.3bn USI Exit to Aon

A buyout firm that keeps a stake for itself

Most private equity firms make their money from other people's capital. They collect management fees on what their limited partners commit and take a share of the profits when they sell. KKR has spent years building a second business on top of that model, one that puts its own money into companies. The payoff from that bet arrived at the end of August, and it was large.

On August 31, KKR agreed to sell USI Insurance Services to Aon for $17 billion in cash. The buyer is acquiring the business from KKR and its co-investors.48 KKR says the sale should bring in about $3.3 billion after tax and roughly $2 billion of adjusted net income, which works out to more than $2 a share.45 The Financial Times' Lex column framed the deal as evidence that KKR is unusual among buyout houses because it bets on itself. Its summary argued that as buyout groups reach middle age, managing outside money only takes them so far.5 My view is that the USI sale does more than produce a big gain. It is the first real test of whether a private equity firm's balance sheet can behave like a long-term holding company, and on this deal it passed.

What KKR actually sold

USI is the tenth-largest insurance brokerage in the US, a fact Bloomberg reported.42 It has more than 10,500 employees in nearly 200 offices.48 KKR first invested in 2017, when the deal valued the company at about $4.3 billion. It put in more money in 2020, 2023 and 2025.45 While KKR owned it, USI nearly tripled its revenue through organic growth and more than 90 bolt-on acquisitions. Adjusted revenue grew about 12% a year and adjusted EBITDA about 13%.48

The return depends on how it is measured. Some coverage led with a sixfold gain.44 That number refers only to the original 2017 equity. KKR's own release puts the return at 3.4 times when every dollar of balance-sheet capital invested over nine years is counted.48 One analysis made this point explicitly, noting that the 3.4x figure includes the three follow-on investments.46 The 3.4x figure is the fairer measure of what KKR earned. It is still an excellent result for a nine-year hold.

The "mini Berkshire" gets its first big test

Where KKR held USI matters more than the multiple. The company was not in a conventional buyout fund with a fixed life. It sat in Strategic Holdings, the segment KKR created in 2023 to own durable, dividend-paying businesses directly. Bloomberg described the unit as a "mini Berkshire."42 KKR set up the segment when it bought the remaining 37% of its insurer, Global Atlantic, for about $2.7 billion, paid from a balance sheet that held $23 billion of cash and investments at the time.29 The segment was built from KKR's core private equity holdings, which then totaled $35 billion of assets under management, of which $6.5 billion sat on the firm's own books.28

The company's description makes clear why the structure is unusual. Through Strategic Holdings, KKR invests its own capital in portfolio companies and earns investment returns on top of the fees and carried interest it collects from outside investors.48 USI was KKR's first core private equity investment.48 The holdings had mostly been a promise until this sale. Commentators observed that the unit produced only about $232 million of earnings last year, against a goal of more than $1 billion by 2030.46

The reported figures for Strategic Holdings vary. Bloomberg and Private Equity Wire cite about $232 million of earnings in 2025.4349 KKR's second-quarter materials cite $187 million of segment operating earnings over the trailing twelve months, with a target above $1.1 billion by 2030.34 The difference most likely comes from KKR reporting more than one measure for the segment: one that includes dividends plus realized investment income, and an operating-earnings line. Either way, the segment's recurring earnings are still small. USI's one-time gain dwarfs a full year of them.

Analysts noticed the gap. On the second-quarter call, a BMO analyst called the Strategic Holdings trajectory "hockey stick shaped." The segment earned only $37 million in the quarter against a 2026 target of more than $350 million.31 The USI sale does not turn that curve into a straight line. It does show that the assets KKR has been holding can be sold for real cash at a strong price.

An exit in a market short of exits

The timing explains much of the attention. Private equity has a well-documented backlog of companies it cannot sell. PitchBook data cited in industry reports put about $3.8 trillion of value in roughly 32,000 unsold companies.16 Holding periods are approaching seven years, and distributions to investors as a share of net asset value have been at record lows for four straight years.18 McKinsey estimates that 16,000 companies have been held for more than four years, or 52% of buyout-backed inventory, the highest share it has recorded.14

The first half of 2026 brought only partial relief. S&P Global Market Intelligence counted 1,504 global exits in the first half, down 6% from a year earlier. Second-quarter exits were the lowest for any quarter since early 2024.15 In the US, exit value fell 46% from the prior quarter in the second quarter, and deals of $1 billion or more accounted for more than 61% of the total.16 Allianz described a market in which the largest, highest-quality assets can find buyers and much of the rest of the inventory cannot.12

The broad trend is consistent across these sources: quality assets sell, and the rest wait. The forecasts differ on how quickly that changes. Allianz's baseline projects a meaningful improvement in distributions in 2026.12 The S&P data and mid-year reports show momentum stalling in the second quarter.1516 The evidence available by autumn favors the more cautious view.

USI fits the pattern where things are working. It was a large, high-quality business sold to a strategic buyer. One analysis argued that a listed acquirer can pay for cost savings and other synergies that no financial buyer could capture, and that this explains why the price was not available from another sponsor.46 Aon is paying about 14.5 times USI's trailing adjusted EBITDA on a synergized basis. It is funding the whole deal with new debt and pausing share buybacks.44 Aon's shares fell about 7% on the announcement while KKR's rose about 2%.44 Investors clearly saw KKR as the side that got the better deal.

KKR's results look unlike its peers'

USI follows a run of strong exits. In the second quarter KKR reported $848 million of realized performance income, the largest monetization quarter in its history, plus $220 million of realized investment income.34 The firm sold eight portfolio investments in the quarter, including stakes in Kokusai Electric and HD Hyundai Marine Solution.38 Bloomberg's figure for the quarter's asset sales was $1.29 billion.41 That does not exactly match the two income lines KKR reported, so the figures are likely measured on different bases.

Fundraising has followed the cash coming back to investors. KKR raised a record $23 billion for its latest Americas buyout fund, while several listed rivals missed their targets.41 It has raised $305 billion since the start of 2024, six months ahead of its three-year goal of $300 billion.34 Co-CEO Scott Nuttall said the firm sits on "the happy part of the K," his description of an industry splitting into winners and strugglers.38 With LPs increasingly judging managers on cash actually returned, the link between exits and new fundraising looks more like cause and effect than coincidence.11

The caveats

The picture is not entirely positive. KKR's shares were down about 22% for the year at the time of its second-quarter results.31 Management dropped its formal target of $7 in adjusted net income per share because, in the CFO's words, it had become a distraction.32 Bloomberg Intelligence now expects the USI gain to put 2026 adjusted net income well ahead of that $7 goal.43 A one-time sale can do that for a single year. It does not create the steady earnings stream the Strategic Holdings model was sold on.

There is also some regulatory friction. In late August KKR agreed to pay a record $250 million to settle a Justice Department lawsuit over its buyout filings. The firm said it disagreed with the government's claims and had acted in good faith.5 Investing its own capital also concentrates risk: when a holding loses value, KKR's own shareholders absorb the loss rather than its funds' investors.8

My reading

The Lex framing is right, and the USI sale supports it. For years KKR's critics could argue that a buyout firm holding companies on its own balance sheet was taking on risk while pretending to be an asset manager. USI weakens that argument. A nine-year hold, built up through more than 90 acquisitions, sold to a strategic buyer at 3.4 times invested capital, is the kind of result the structure was designed to produce.

The broader point for private equity is the uncomfortable part. KKR can afford patience because its own capital does not have a fund deadline forcing a sale. Most of its rivals do face that clock, and with an exit backlog in the trillions they are selling into a market that rewards only their best assets.19 Many of them may now try to copy KKR's approach, but adopting it requires a balance sheet of comparable size, which few of them have.
