Leveraged Buyout (LBO)
Think of an LBO like buying a house with a big mortgage — the PE firm puts down a small equity check, borrows the rest, and uses the company's own cash flow to pay off the debt. If the company grows, the equity value skyrockets.
Definition
A Leveraged Buyout (LBO) is the acquisition of a company using a significant amount of borrowed money (debt) to fund the purchase price. The target company's free cash flows are used to service and repay the debt over the hold period, while the private equity firm invests a smaller equity check and aims to exit at a higher enterprise value.
Formula
Equity Value at Exit = Exit Enterprise Value - Net Debt at Exit MOIC = Equity Value at Exit / Initial Equity Investment IRR = (MOIC)^(1/years) - 1 (simplified for single cash flow) Entry EV = Entry EBITDA × Entry Multiple Exit EV = Exit EBITDA × Exit Multiple Debt Paydown = Cumulative FCF applied to debt repayment

How an LBO Works
A PE firm identifies a target, structures the financing (typically 50–70% debt, 30–50% equity) laid out in the sources & uses table, acquires the company, improves operations over a 3–7 year hold period, and exits via sale or IPO. The debt is secured by the target's assets and must satisfy debt covenants. Because the PE firm only invests 30–50% of the purchase price in equity, even modest enterprise value growth can generate outsized equity returns. This 'leverage effect' is the fundamental principle behind LBOs.
Four Drivers of LBO Returns
- EBITDA Growth: Operational improvements, revenue growth, and margin expansion increase the base for valuation. 2) Multiple Expansion: Selling at a higher EV/EBITDA multiple than the entry multiple. 3) Debt Paydown: Using FCF to repay debt increases equity value dollar-for-dollar. 4) Timing: Returning capital faster boosts IRR. The best LBO returns come from all four working together. In a base case, assume the exit multiple equals the entry multiple (no multiple expansion) to be conservative.
Ideal LBO Candidate
The best LBO targets have: stable, predictable cash flows (to service debt), strong market position with high barriers to entry, low CapEx requirements (maximizing FCF), opportunities for operational improvement (cost cutting, pricing power), a fragmented industry allowing for add-on acquisitions, and asset-heavy balance sheets that can secure debt. Industries like healthcare services, business services, industrials, and food & beverage are classic LBO sectors. High-growth tech companies are generally poor LBO candidates (volatile cash flows, high reinvestment needs).
LBO Return Targets
PE firms typically target 20–25% gross IRR and 2.0–3.0x MOIC on individual deals. Fund-level returns are lower after fees (management fees + carry). A simplified LBO return: entry at 8x EBITDA, $100M EBITDA, 60% leverage ($480M debt, $320M equity). Over 5 years, EBITDA grows to $130M, $200M debt repaid, exit at 8x = $1.04B EV. Equity = $1.04B - $280M remaining debt = $760M. MOIC = $760M / $320M = 2.4x. IRR ≈ 19%.
Worked Example — With Real Numbers
Entry: $100M EBITDA × 10x = $1B EV. 60% debt ($600M), 40% equity ($400M). Over 5 years: EBITDA grows 5%/yr to $128M, $250M debt repaid, exit at 10x. Exit EV = $1.28B. Net Debt = $350M. Equity at Exit = $930M. MOIC = $930M / $400M = 2.3x. IRR ≈ 18.4%.
Key Takeaways
LBOs are funded 50-70% with debt and 30-50% with equity — leverage amplifies returns (and risk)
Four return drivers: EBITDA growth, multiple expansion, debt paydown, and timing of cash flows

Common Mistakes in Interviews
Assuming multiple expansion in the base case — conservative models assume exit multiple equals entry multiple
Picking a high-growth tech company as an LBO candidate — volatile cash flows and high reinvestment needs make debt service risky
Confusing MOIC and IRR — a 3x return in 10 years (~12% IRR) is very different from 3x in 3 years (~44% IRR)
Forgetting transaction fees in the sources & uses — advisory, legal, and financing fees typically run 2-5% of enterprise value
How Interviewers Test This
LBO questions are guaranteed in PE interviews and common in IB. Be able to: 1) Describe how an LBO works conceptually, 2) Name the four return drivers, 3) Walk through a simplified 'paper LBO' with numbers, 4) Describe the ideal LBO candidate. Follow-up: 'How do you increase IRR in an LBO?' — use a dividend recap, reduce the purchase price, improve EBITDA faster, or exit sooner. Practice with the IB Quiz.
