A leveraged buyout is simple arithmetic with deep psychology. You buy a company mostly with borrowed money, let the company's own cash flow repay the debt, and sell it later. Every rupee of repaid debt becomes a rupee of equity value, on top of any growth in the business itself.
How does a leveraged buyout work in numbers?
Start with a toy deal that has all the logic and none of the schedules. Buy a business generating EBITDA of $100m at 8.0×, so enterprise value is $800m. Fund it 60/40, with $480m of debt and $320m of equity. Hold it five years. EBITDA grows a modest 5%/year to $127.6m at exit. Sell at the same 8.0×, and exit EV = $1,021m. Along the way the company's free cash flow repaid $200m of debt, which leaves exit debt of $280m. Exit equity = 1,021 − 280 = $741m.
MOIC (multiple on invested capital) = 741 / 320 = 2.32×
IRR = (741/320)^(1/5) − 1 = 18.3% per yearNow decompose the $421m equity gain, the standard value-creation bridge:
| Driver | $m | Share |
|---|---|---|
| EBITDA growth at constant multiple: (127.6 − 100) × 8.0 | +221 | 52% |
| Multiple expansion: (8.0 − 8.0) × 127.6 | 0 | 0% |
| Debt paydown (deleveraging) | +200 | 48% |
| Total equity gain (320 → 741) | +421 |
Half the profit came from the business, and half came from the capital structure, as cash flow turned lenders' claims into owners' claims. Compare what the same asset returns unlevered. EV grew from 800 to 1,021, which is 28% over five years, or ≈ 5%/year, plus the free cash flow the owner pockets. Call it ~11 to 13%, and the full LBO computes it properly. Leverage turned a ~12% asset into an ~18% equity return without improving the business at all.

How does leverage cut both ways, and which lever matters?
Now run it in reverse, the part every LBO pitch leaves out. Same deal, but EBITDA falls 20% to $80m and the exit multiple contracts to 7.0×, so exit EV = $560m. Weak cash flow means debt only fell to $440m. Exit equity = 560 − 440 = $120m: MOIC 0.38×, IRR −17.8%. You lost 62% of your money on a business whose enterprise value fell only 30%, an unlevered MOIC of 0.70×. Leverage is a lens that magnifies whatever passes through it, in both directions. Debt holders feel none of it until you're near zero, because equity takes the first loss. That asymmetry, with equity as the thin slice that absorbs all the variance, is the most transferable idea here. It's the same idea as promoter pledging risk (M2), banking leverage (Phase 5) and position-sizing ruin (Phase 9).
Every LBO return breaks down into three levers.
- EBITDA growth is operating improvement, and it's the defensible lever.
- Multiple expansion, buying at 8× and selling at 10×, is the market-timing lever. Underwrite deals at flat or contracting multiples, and treat any expansion as luck.
- Deleveraging is cash flow paying down debt. It's the mechanical lever, and the business's FCF conversion puts a ceiling on it.
Sponsors underwrite to ~20 to 25% gross IRR, or ~2.0 to 2.5× MOIC, over 4 to 6 years. When you see a realized 3×+, ask which lever did it. Growth is skill, expansion is luck, and leverage is rented.
Why does a public-market analyst care about LBOs?
Why should a public-market analyst care? For three reasons.
- An LBO floor. If a sponsor could underwrite a 20% IRR buying the whole company at a 30% premium, the stock has a natural bidder beneath it. Work out what a sponsor could pay, as the toolkit section shows, and you have a floor estimate under your football field.
- Pattern recognition. Levered equities are LBOs. A company at 4× net debt/EBITDA is a live experiment in the reverse-gear math above.
- History's lab. Start with RJR Nabisco, KKR's ~$25bn deal of 1989 that named an era, and read Barbarians at the Gate. Then there's Hilton. Blackstone paid ~$26bn for it in 2007, with ~$20bn of debt, at the worst possible moment. Operational growth and patience rescued it into roughly a 3×, a ~$14bn reported profit and the most profitable single PE deal on record (figures as reported). And then Twitter/X in 2022, $44bn with ~$13bn of debt whose interest bill exceeded the company's pre-deal EBITDA. Leverage without free cash flow is a countdown timer.
Are leveraged buyouts common in India?
In India, classic onshore LBOs are rare, because Indian banks are restricted from financing share acquisitions. Buyout debt is typically raised offshore or through NBFC/AIF structures instead. Indian "buyouts" such as Blackstone–Mphasis and Baring–NIIT Tech/Coforge run the same math with different plumbing, plus the promoter-exit dynamics you already know from M2.
