What Is a Secondary Buyout?
A secondary buyout, sometimes abbreviated SBO, occurs when a private equity sponsor sells a company it owns to a different private equity sponsor, usually through a new leveraged buyout. The selling fund realizes its return and distributes proceeds to limited partners, while the buying fund starts a fresh hold period with its own debt package, its own board, and its own value creation plan.
Secondary buyouts sit alongside sales to strategic acquirers and initial public offerings as the main exit routes for sponsors. They have grown from a niche outcome into a structural feature of the industry, in some years accounting for roughly 40% of buyout exits, because record levels of dry powder mean there is almost always another fund willing to underwrite a well-performing asset.
How These Deals Work
Mechanically, a secondary buyout looks like any other LBO. The seller typically hires an investment bank to run an auction process, distributing a confidential information memorandum to a list of sponsors and strategics. Because the target has already lived under private equity ownership, it usually arrives with clean reporting, an incentivized management team, and a track record of hitting budgets, which makes diligence faster and financing easier to arrange.
The buyer's challenge is finding a new angle. The first sponsor may have already cut costs and professionalized operations, so the second owner needs a different thesis, such as international expansion, a buy-and-build campaign in a fragmented market, or a push into adjacent products. Management often rolls a portion of its equity into the new deal, and continuation vehicles, where the same sponsor sells a company to a new fund it also manages, have emerged as a related variant.
Why It Matters
For investors, secondary buyouts raise a real analytical question about returns. Buying from a sophisticated seller means the obvious improvements are likely done and the price is rarely a bargain, so entry multiples in SBOs tend to run higher than in founder or corporate carve-out deals. Academic evidence is mixed, with some studies finding SBOs underperform primary buyouts, particularly those done late in a fund's life when the buyer is under pressure to deploy capital.
For candidates, the term is interview-relevant in several ways. You should be able to name secondary buyouts among the standard exit assumptions in an LBO model, discuss why a sponsor might prefer a quick, certain sale to another fund over a lengthy IPO, and articulate what a second owner could still do to create value. That last question is a favorite because it tests judgment rather than memorization.
