Leveraged Buyout (LBO)

Formulas

How an LBO is structured

The sponsor usually forms a chain of new holding companies, often called topco, midco and bidco. The fund, any co-investors and managers who roll over part of their existing stake subscribe for equity at the top; bidco borrows the acquisition debt and buys the target. Lenders take security over the target group's assets and guarantees from its subsidiaries, and are repaid from the group's cash flow or from sale or refinancing proceeds. The fund is not the borrower and does not normally guarantee the debt: lenders' recourse is limited to the acquired group, and a failed deal costs the fund its equity.

The debt is usually layered. A senior secured tranche (first-lien term loans, a term loan B in the syndicated market, or a single unitranche facility from direct lenders) sits alongside a revolving credit facility, with second-lien loans, high-yield bonds, mezzanine or holding-company payment-in-kind (PIK) notes below it in some deals. Lenders size the debt against EBITDA, cash flow and interest cover, and the amount moves with credit conditions, so no fixed share of the purchase price is standard. Leverage is quoted as debt-to-EBITDA, usually on an adjusted EBITDA definition negotiated in the credit agreement. Private credit loans of this kind are typically negotiated bilaterally and floating-rate, and Federal Reserve staff identify borrower leverage as one of the main risks in that market.

The value bridge

A value bridge splits the equity gain into its sources. In the illustrative deal, the $690 million gain on the $480 million invested splits into EBITDA growth valued at the entry multiple, $400 million (58%); multiple expansion applied to exit EBITDA, $70 million (10%); and net debt reduction from cash generation, $250 million (36%); less $30 million of entry fees funded with equity (−4%).

The split depends on the order of measurement. Valuing EBITDA growth at the exit multiple and the multiple change on entry EBITDA gives $420 million and $50 million instead; the $20 million difference is the interaction between growth and re-rating, which every bridge must assign somewhere. Bridges also differ in whether they separate revenue growth from margin change, show EBITDA bought through add-on acquisitions apart from organic growth, and show fees, dividends and management dilution as separate bars. Two bridges can be compared only if they use the same convention.

Leverage cuts both ways

Debt lets the sponsor control a business with a smaller equity cheque. The tax treatment of acquisition debt differs by jurisdiction. The price is a fixed claim ranking ahead of the equity. In the downside example a 20% fall in enterprise value removes about half of the equity. Over-levered buyouts typically get into trouble through rising floating rates, covenant breaches, or maturities that fall due when credit markets are closed; lenders monitor interest coverage and covenant headroom for that reason.

Exit routes

Sponsors realise LBOs through a trade sale to a strategic buyer, a secondary buyout to another sponsor, an IPO followed by sell-downs, or partly through a dividend recapitalisation that returns cash funded with new debt. Each route changes the timing of cash flows and therefore the IRR, even when the total value realised is similar.

Evidence on buyout returns

Fund-level studies disagree in degree. In Burgiss data, Harris, Jenkinson and Kaplan (2014) found that US buyout funds returned 20% to 27% more than the S&P 500 over fund life, more than 3% a year. Phalippou and Gottschalg (2009) found that average private equity fund returns, net of fees, lagged the index by about 3% a year in their sample, and argued that reported valuations of unrealised investments overstated performance. Kaplan and Schoar (2005) found average net returns close to the index, wide dispersion between funds and persistence across a manager's funds. The studies use different data, periods and samples, and none establishes that one value-creation lever dominates across deals.

How LPs and lenders read an LBO

LPs diligencing a buyout manager look at entry multiples and leverage relative to the market at the time, the share of past gains that came from earnings growth rather than re-rating, how EBITDA adjustments were treated, and how deals behaved in downturns. Lenders look at the same deal from below: the equity cushion beneath their claim, cash-flow cover of interest, the quality of the EBITDA used to size the debt (often tested in a quality-of-earnings report) and the covenant package. A sponsor's gross deal multiple on invested capital (MOIC) and IRR are not the LP's return: the LP's net figures come after management fees, the fund's own expenses and the GP's carried interest.

Worked examples

Examples are illustrative; figures are not market data.

Not the same as

• Management Buyout: A management buyout (MBO) is defined by who buys (the existing managers, usually with a sponsor); an LBO is defined by control and debt financing. Many MBOs are LBOs.
• Dividend Recapitalization: A dividend recapitalisation adds debt to a company the sponsor already controls and pays the proceeds to shareholders; an LBO uses debt to acquire control.
• Growth Equity: Growth equity usually buys a minority stake with little or no acquisition debt.
• Take-Private: A take-private is the acquisition of a listed target, usually structured as an LBO; LBOs also cover private targets.

How it is classified

• Classify a transaction as an LBO when a financial sponsor, or a sponsor-led group that may include management, acquires control and a material part of the price is financed with debt raised against the target's own cash flows and assets.
• A strategic buyer funding an acquisition from its balance sheet or corporate borrowing is not making an LBO.
• MBO, take-private, carve-out and secondary buyout describe the buyer, seller or target; LBO describes control and financing. One deal can carry several labels.
• A minority investment without acquisition debt is not an LBO, even when made by a buyout fund.

Common mistakes

• Quoting a fixed debt share of the purchase price (for example "50% to 70%") as standard. Debt is sized deal by deal against EBITDA, cash flow and coverage, and changes with credit conditions.
• Calculating returns on the equity value acquired rather than the actual equity cheque, which also pays fees and expenses.
• Saying the fund borrows the acquisition debt. The acquired group borrows; fund-level facilities such as subscription lines are separate.
• Comparing leverage multiples without checking whether EBITDA is reported, adjusted or pro forma.
• Presenting a value bridge without stating its ordering convention or without separating acquired EBITDA from organic growth.
• Treating gross deal MOIC or IRR as the LP's net return.
• Stating as settled that operational improvement, rather than leverage or multiple expansion, drives buyout returns. The evidence is mixed and period-dependent.

Edge cases

• Sponsor shareholder loans or PIK preferred shares are legally debt or preference capital but economically part of the sponsor's investment; include them in the equity cheque for sponsor returns and exclude them from third-party leverage.
• Equity injected during the hold (to fund add-ons or cure a covenant breach) adds outflows; MOIC and IRR must then use the dated series.
• A dividend recapitalisation returns cash early: it raises IRR and distributions to paid-in capital (DPI) and increases leverage without changing total value created.
• In a consortium (club) deal several sponsors each hold a minority stake while the group controls the company.
