   Say this

   Buy a company using mostly debt, use its own cash flow to pay that debt down over five years, then sell it. The equity return comes from deleveraging, from growing EBITDA, and from any multiple expansion.

   Then walk it

   1. Set the entry: purchase price as a multiple of EBITDA, then a sources and uses table. Debt takes you as far as the credit market allows, say five times EBITDA, and the sponsor writes a cheque for the rest plus fees.
   2. Project the operating model for five years, then build the debt schedule: interest, mandatory amortisation, and a cash sweep that applies surplus cash to the debt.
   3. Free cash flow after interest pays down debt each year, so the equity slice grows even if enterprise value does not move at all. That is deleveraging.
   4. Exit at an assumed multiple on final-year EBITDA, subtract the remaining debt, and you have exit equity value.
   5. Compute IRR and money multiple against the initial cheque. Then attribute the return across the three drivers: debt paydown, EBITDA growth and multiple change. A sponsor will always ask which one is carrying the deal.
   6. The sanity test: if the whole return depends on exiting at a higher multiple than you paid, it is not an investment thesis, it is a bet on the market.

   Where candidates lose it

   Describing the mechanics with no attribution of returns. Every good LBO answer ends with which of the three drivers produces the IRR, and an acknowledgement that multiple expansion is the one you cannot control.

   Say this

   Three levers: pay down debt with the company's cash flow, grow EBITDA through revenue and margin, and exit at a higher multiple than you paid. The first two you control, the third you mostly do not.

   Then walk it

   1. Deleveraging: every dollar of debt repaid transfers a dollar of enterprise value to the equity. At five times leverage this alone can double equity over five years with no growth at all.
   2. EBITDA growth: organic revenue growth, pricing, cost programmes, and bolt-on acquisitions. Bolt-ons are especially powerful because a small target bought at six times inside a platform valued at twelve times creates value on day one through multiple arbitrage.
   3. Multiple expansion: selling at a higher multiple, either because the market re-rated or because you made the asset more valuable, bigger, more diversified, faster-growing.
   4. A fourth, less discussed: the dividend recap. Refinancing to pull cash out early shortens the duration of the return and lifts IRR without any exit.
   5. The discipline point: a sponsor's investment committee wants to see the return work on deleveraging and EBITDA alone, with flat or lower exit multiples. Anything that only works on multiple expansion does not get approved.

   Where candidates lose it

   Naming only leverage. Leverage amplifies returns; it does not create them. And forgetting that IRR is time-sensitive, so the speed of the return matters as much as the size.

   Expect next

   • Which lever matters most?
   • What would you do in the first hundred days?
   • How does a dividend recap change the IRR?
