LBO Interview Questions: The Conceptual Ones Behind the Maths

"What makes a good LBO candidate?"

• Stable, predictable cash flows — debt service does not tolerate volatility; this is why subscription revenue and non-cyclical demand are prized.
• Low ongoing capex needs — cash that must go into machinery cannot go into debt paydown.
• A deleveraging path or operational upside the current owner is not capturing.
• Defensible market position — leverage amplifies downside, so moats matter more, not less.
• A credible exit: sponsors underwrite the sale on the way in. "Great business, no plausible buyer at exit" is a pass.

"Where do LBO returns actually come from?"

Three drivers, and interviewers want them decomposed, not listed: debt paydown (cash flows repay debt, transferring enterprise value from lenders to equity), EBITDA growth (a bigger business at exit), and multiple expansion (selling at a higher multiple than entry — the driver disciplined underwriters assume LEAST, because it depends on market conditions rather than anything the sponsor controls).

A strong answer notes the interaction: leverage amplifies whichever way the operating performance goes. The same 20% EBITDA decline that dents an unlevered business can wipe out the equity in a 6x-levered one.

"Why not use as much leverage as possible?"

Because leverage prices in fragility: more debt means higher interest cost eating cash flow, tighter covenant headroom, less room for operational missteps, and a business that cannot invest through a downturn. Lenders cap it anyway (leverage and coverage constraints), but the better answer is that the sponsor should not want maximum leverage on a business whose cash flows do not support it — the equity option is only valuable if the company survives to exit.

The follow-up traps

• "Would you rather have 20% EBITDA growth or 2 turns of multiple expansion?" — do the maths live with round numbers, then note growth is (partly) controllable while exit multiples are not.
• "How does an LBO create value if nothing about the company changes?" — honest answer: pure deleveraging transfers value to equity, but the *price* was set competitively; with no operational plan, returns depend on the entry price being wrong. This is why "financial engineering alone" is a criticized model.
• "What happens to IRR if the hold extends from 5 to 7 years at the same MOIC?" — IRR falls (same multiple over longer time); candidates who cannot reason this way trip on it constantly.
• "Walk me through how a dividend recap changes the returns" — capital returned early boosts IRR (time value) and de-risks the position, while MOIC stays a function of total cash returned.

How to prepare

Drill the paper LBO until the arithmetic is automatic (our free trainer generates a fresh one each run) — then spend equal time practising these conceptual answers out loud. The maths gets you to par; the concepts are the differentiator.
