1. 004Do a paper LBO. EBITDA of $100, bought at 10 times, five turns of leverage, exit at the same multiple in five years with EBITDA at $150.LBO mechanicsHardtechnicalBain CapitalGeneralist · Boston · 2024WPWarburg PincusPrivate Equity · New York · 2014Clayton Dubilier and RicePrivate Equity · London · 2026

   Say this

   Entry equity is $500. With about $250 of debt repaid over five years, exit equity is $1,500 less $250, so $1,250. That is 2.5 times the money and roughly a 20 percent IRR.

   Then walk it

   1. Entry: $100 EBITDA at 10 times is $1,000 enterprise value. Debt at five turns is $500, so the sponsor writes $500.
   2. Cash generation: EBITDA ramps from $100 to $150, averaging about $125. Interest on $500 at 8 percent is roughly $40. Less CapEx of $25, working capital of $5, and cash taxes on EBIT.
   3. That leaves around $50 a year to sweep, so about $250 of debt repaid. Ending debt is $250.
   4. Exit: $150 at 10 times is $1,500, less $250 of debt, equals $1,250 of equity.
   5. Return: $1,250 on $500 is 2.5 times. Using the standard grid, 2.0 times over five years is about 15 percent, 2.5 times is about 20 percent, 3.0 times is about 25 percent.
   6. Attribution: EBITDA grew 50 percent and debt halved, with no multiple expansion assumed. That is the version an investment committee likes, because the return does not depend on the exit market.

   Where candidates lose it

   Reaching for a calculator or chasing decimal precision. Round hard, state every assumption out loud, and know the IRR grid cold. Also announce your interest rate and CapEx assumptions rather than letting them appear silently.

   Expect next

   • What if you exit at 8 times?
   • What return does the fund actually need?
   • How much of that return came from each driver?

2. 007What makes a good LBO candidate?Investment judgementCorefirst roundWPWarburg PincusPrivate Equity · San Francisco · 2014Clayton Dubilier and RicePrivate Equity · London · 2026GSGuggenheim SecuritiesHealthcare · London · 2026

   Say this

   Predictable cash flow that can service debt, low capital intensity, a defensible market position, a clear operational improvement to make, and a credible exit. Stability matters more than growth.

   Then walk it

   1. Cash flow stability first, because debt service is non-negotiable. Contracted or recurring revenue, low cyclicality, sticky customers, and a demonstrated ability to hold margin through a downturn.
   2. Low maintenance CapEx, since every dollar spent on the asset base is a dollar not repaying debt.
   3. Defensible position: switching costs, scale, regulation, brand. Something that protects margin for the five years you own it without requiring you to outspend competitors.
   4. An identifiable value creation lever: an underinvested commercial function, a bloated cost base, a fragmented sector supporting a buy-and-build, or a non-core division to divest.
   5. A real exit. A deep strategic buyer list, or a listed peer group at a decent multiple. The best entry price is worthless if nobody will buy it from you in five years.
   6. And the anti-candidate, which is worth naming: high-growth, cash-burning, cyclical, capital-heavy. That can be an excellent investment and a terrible LBO, and knowing the difference is the point of the question.

   Where candidates lose it

   Putting high growth near the top. Growth consumes cash and cash service is the binding constraint. Saying that venture-style growth is the opposite of what an LBO structure wants shows you understand why the structure exists.

   Expect next

   • Pitch me a company that would be a great LBO candidate.
   • Why is high growth not necessarily good?
   • Would you invest in a company with negative sales growth?

3. 008Pitch me a business that would be a great LBO candidate, covering market drivers and both financial and non-financial qualities.Investment judgementHardsuperdayClayton Dubilier and RicePrivate Equity · London · 2026GSGuggenheim SecuritiesHealthcare · London · 2026

   Say this

   Pick a real company, ideally mid-cap and slightly unglamorous, and structure it as: why the market works, why this asset wins in it, what you would do differently as owner, how you would fund it, and how you would exit.

   Then walk it

   1. Market first: growing or at least stable demand, fragmented enough to consolidate, with a driver you can name, regulation, outsourcing, demographics, infrastructure spend.
   2. Then the asset: recurring revenue, contracted or repeat, gross margin stability, customer concentration low enough to be safe, and a defensible position you can describe in one sentence.
   3. Then the value creation plan, which is the part most candidates skip. Be specific: pricing that has not been touched in years, a sales force with no CRM discipline, three acquirable competitors in adjacent geographies, a non-core division to sell.
   4. Then the financing: what leverage the cash flow supports, what the interest burden looks like, and whether covenants would be comfortable in a downside case.
   5. Then the exit: who buys it in five years and why. Name actual acquirers, and say what the asset would look like at exit compared with today.
   6. Then the risks and what would stop you. A pitch with no acknowledged risk reads as a sales document rather than an investment case.

   Where candidates lose it

   Pitching a household name that is far too large or obviously not leveragable. Pick something with a realistic enterprise value for the fund you are interviewing with, and lead with the value creation plan rather than the financials.

   Expect next

   • How much leverage would it support?
   • Who buys it from you in five years?
   • What is the biggest risk?
