Leveraged buyout (LBO): What it is and how it works

Key Takeaways

• A leveraged buyout finances a company purchase with a mix of debt and equity, with debt typically covering the larger share.

• Common LBO structures include management buyouts (MBOs), management buy-ins (MBIs), and secondary buyout.

• Private equity firms use LBOs to acquire larger companies while committing less of their own fund capital.

• Lenders and bond investors supply the debt through term loans, high-yield bonds, and mezzanine financing.

• A typical private equity holding period runs four to seven years, ending in a sale, an IPO, or a dividend recapitalization.

• Debt service obligations are fixed, so a drop in revenue or cash flow raises the risk of default or bankruptcy.

What is a leveraged buyout (LBO)?

A leveraged buyout is when a company gets bought using a large amount of borrowed money, backed by the assets and expected future earnings of the company being bought. The buyer pays a comparatively small amount out of its own pocket, often 20% to 50% of the purchase price, and covers the rest with bank loans and bonds.

Once the deal closes, the purchased company owes the debt, not the buyer. The company's earnings pay down that debt over time. If the company grows in value and pays off enough debt, the owners profit when they eventually sell.

The mix of debt and cash used in an LBO changes with the economy and interest rates. In the late 1980s, some deals were financed with 80% to 90% debt. Today, most deals use less, commonly 50% to 65% debt, because banks are more cautious about how much debt a company can safely carry.

Types of Leveraged Buyout

LBOs take different forms depending on who initiates the deal and who runs the company afterward.

Management buyout (MBO)

In an MBO, the people already running the company buy it from its current owners. They pay with a mix of their own savings, outside investors, and borrowed money. Because the managers already know the business inside and out, the transition tends to go more smoothly.

Management buy-in (MBI)

An MBI is the opposite setup: an outside management team, usually backed by a private equity investor, buys the company and takes over running it. Investors go this route when they believe a new leadership team can grow the business faster than the current one. Since the new managers are learning the company for the first time, an MBI carries more risk during the transition than an MBO does.

Secondary Buyouts

A secondary buyout is when one private equity firm sells a company it owns to another private equity firm, instead of to an outside company or through a stock market listing an initial public offering, IPO. This has become a common way for private equity firms to exit an investment, especially for stable, mid-sized companies that still have growth left in them under a new owner.

How does an LBO Work?

A leveraged buyout generally moves through these stages:

• Identify a target with stable cash flow, then run diligence on its finances and market position.

• Raise the debt, typically a mix of bank loans, bonds, and mezzanine capital.

• Secure that debt against the target company’s assets to lower the lender’s risk.

• Project the cash flows that will service interest and fund operations across the hold.

• Take control, then act on the operating changes the model assumed.

How are leveraged buyouts financed?

An LBO is rarely paid for with one type of loan. Buyers usually stack a few layers of financing together:

• Bank loans: Loans from banks, backed by the target company's assets, which get paid back first if anything goes wrong.

• High-yield bonds: Bonds sold to investors that pay a higher interest rate because they carry more risk and get paid back after the bank loans.

• Mezzanine financing: A flexible layer of financing that sits between debt and ownership. It's often structured as a loan that also gives the lender some right to future ownership or profit, and it's used to fill any gap left after the other financing is in place.

• Seller notes: A loan from the company's previous owner to the buyer, repaid over time. It's sometimes used to close the gap when the buyer and seller can't agree on price.

• Investor cash: The money the private equity fund and its co-investors put in themselves. This money is at the most risk if the deal goes badly, but it also earns the biggest reward if the deal goes well.

How does a leveraged buyout work in private equity?

Two US federal tax provisions can affect the economics of an LBO, although they apply to different parties:

• Carried interest: Section 1061 generally recharacterizes certain net long-term capital gains associated with an applicable partnership interest as short-term capital gains unless the relevant asset satisfies a holding period of more than three years. For individual taxpayers, net short-term capital gains generally face ordinary income tax rates. Section 1061 does not apply identically to every component of a fund manager’s compensation or investment return.

• Business-interest deductions. Section 163(j) generally limits deductible business-interest expense to the sum of business-interest income, 30% of adjusted taxable income, and floor-plan financing interest. Exceptions and entity-specific rules apply. For tax years beginning after December 31, 2024, depreciation, amortization, and depletion deductions are once again added back when adjusted taxable income is calculated.

These rules are complex and may operate differently depending on the fund structure, taxpayer, transaction, and tax year. Readers should consult a qualified tax adviser.

How to build a successful LBO model?

The model answers one question: can this deal clear the fund’s return target?

Leveraged buyout examples

Let's analyze the most famous LBOs in corporate history to understand the strategies employed:

1. Squarespace: a recent technology take-private

In October 2024, Permira completed its acquisition of website-building platform Squarespace in a transaction valued at approximately $7.2 billion. The original agreement valued the company at $6.9 billion, but Permira subsequently increased its offer. Squarespace’s SEC filings show that the acquisition was financed through a combination of equity and committed debt, which qualifies it as an LBO.

2. Hilton: a profitable long-term investment

Blackstone acquired Hilton in October 2007 using approximately $20.6 billion of debt and $5.7 billion of equity. The transaction closed shortly before the global financial crisis, which put pressure on the hospitality industry and Hilton’s debt structure. Hilton returned to the public market through an IPO in December 2013, although Blackstone remained its majority shareholder at that time. Blackstone completed its final exit in 2018 and reported a total profit of approximately $14 billion. 

3. Energy Future Holdings: debt magnifying a failed forecast

In 2007, an investor group led by KKR and TPG, with Goldman Sachs Capital Partners and other investors, acquired Texas energy company TXU Corporation in a transaction announced at approximately $45 billion. After the acquisition, TXU was renamed Energy Future Holdings. The investment depended partly on expectations that natural gas prices, and therefore Texas wholesale electricity prices, would remain high. Increased natural gas supply caused both prices to fall, weakening the company’s earnings while its substantial debt remained. Energy Future Holdings and most of its subsidiaries filed for Chapter 11 protection in April 2014. The outcome illustrates why portfolio monitoring in private equity must account for debt capacity, market exposure, and downside scenarios. The TXU transaction was described as the largest private-equity buyout when it was announced in 2007, but it was surpassed in August 2026 by the approximately $55 billion acquisition of Electronic Arts.

Management buyout (MBO) vs. Leveraged buyout (LBO)

An MBO is one specific form of LBO; every MBO uses leveraged financing, but not every LBO is led by the target's own management. Here are the key differences.

Why do companies use leveraged buyouts?

Here are some key motivations behind different companies using LBOs:

1. Improving profitability: One of the primary motivations behind LBOs is the potential to enhance the target company's profitability. By implementing cost-cutting measures, streamlining operations, and optimizing resources, you can increase the company's efficiency and profitability.

2. Growth initiatives: LBOs provide the opportunity to drive growth within the acquired company. Strategic initiatives, such as expanding into new markets, launching new products, or enhancing existing services, can unlock the company's potential and achieve substantial growth.

3. High returns for private equity firms: For private equity firms, LBOs are a pathway to high returns on investment. By improving the target company's operations and financial performance, private equity firms aim to eventually sell the company at a profit or take it public through an Initial Public Offering (IPO). This process allows them to realize significant returns on their investment through a successful exit.

4. Strategic control and flexibility: LBOs allow you to gain control over the target company, helping you make strategic decisions that align with your vision and goals. This control allows for greater flexibility in implementing changes and driving the company towards success.

Exit strategies in leveraged buyouts

• Initial public offering (IPO): The company lists shares on a public exchange, and the sponsor sells its stake gradually over time.

• Strategic sale: A competitor or larger company in the same industry buys the business outright.

• Secondary buyout: Another private equity firm buys the company, often bringing new capital for the next growth phase.

• Dividend recapitalization: The company raises additional debt to pay a special dividend to the sponsor, returning some capital without a full exit.

Benefits and risks

Benefits:

• A buyer can purchase a much bigger company than it could afford with cash alone.

• If the deal goes well, the return on the buyer's own cash can be large, since a small amount of equity captures most of the upside.

• Business interest may be deductible, but Section 163(j) and other federal tax rules can limit or defer the deduction.

• New owners get time and room to fix or grow the business without the pressure of quarterly public shareholder reporting.

Risks:

• The company must make debt payments no matter how the business is doing, which is dangerous if sales drop.

• Lenders usually attach rules to the loan (called covenants) that limit how much more the company can borrow, sell off, or change without permission.

• To free up cash for debt payments, owners sometimes cut costs sharply, including through layoffs.

• If the company can't earn enough to cover its debt, it can be forced into default or bankruptcy, as happened to the Texas utility Energy Future Holdings (formerly TXU) in 2014.

Conclusion

The purpose of a leveraged buyout is simple: buy a company using mostly borrowed money, then use that company's own earnings to pay off the debt and grow its value. When it goes well, the new owners rebuild and grow the business, then sell it for more than they paid. When it goes unexpectedly, the same debt that boosted the potential return can sink a struggling company. If you're a manager, an investor, or an employee at a company going through an LBO, it's worth understanding both sides of that trade-off before the deal closes.

FAQ

What is an LBO in private equity?

In private equity, an LBO is the standard way a firm buys a company: the fund puts in a small equity stake, borrows the rest of the purchase price, and spends the next several years growing the company's value before selling it or taking it public.

What is LBO valuation?

LBO valuation is the process of figuring out the highest price a private equity firm can pay for a company while still hitting its target return, usually 20% to 25% a year (measured as internal rate of return, or IRR). It's based on the company's projected earnings, how much debt the deal can carry, and what the company might sell for down the line.

What is an LBO model?

An LBO model is a spreadsheet built to test whether a leveraged buyout can hit its target return before the deal happens. It projects the company's future revenue and cash flow, maps out the debt payment schedule, and calculates the expected return for the buyer at exit.

How is a business valued in an LBO?

A business is valued in an LBO by projecting its future cash flow and comparing it to what similar companies have sold for recently. The buyer then checks that price against the maximum the company's projected earnings can support in debt payments while still hitting the buyer's target return.

How are candidates qualified for a good LBO?

A good LBO candidate usually has steady, predictable cash flow, since that's what pays down the debt after the deal closes. Buyers also look for a company with low existing debt (so there's room to add more), assets that can back a loan, a strong position in its market, and clear opportunities to cut costs or grow revenue after the buyout. A stable, experienced management team is a plus too, since it lowers the risk during the transition.
