1. 002How does private equity create value?Value creationIntermediatefirst roundEQTInfrastructure · Munich · 2013TPTPGInvestment Banking · New York · 2024

   Say this

   Three financial levers, deleveraging, EBITDA growth and multiple expansion, sitting on top of two real ones: operational improvement and better governance. The financial levers are the arithmetic; the operational ones are the actual work.

   Then walk it

   1. Deleveraging: cash flow repays debt, so enterprise value transfers from lenders to the equity. At five times leverage this alone can double equity over a hold with no growth.
   2. EBITDA growth: organic revenue, pricing, cost programmes, and bolt-on acquisitions. Bolt-ons are especially powerful because buying at six times into a platform valued at twelve creates value on announcement.
   3. Multiple expansion: selling higher than you bought, either because the market moved or because you made the asset genuinely better, larger, more diversified, more recurring.
   4. Underneath those: operational improvement. Professionalising a founder-run business, installing proper reporting, fixing pricing, rationalising the portfolio, upgrading management.
   5. And governance. A concentrated owner with board control and aligned management incentives makes decisions faster than a public company answering to a diffuse shareholder base. That alignment is a genuine structural advantage, not just a story.
   6. The honest framing: in the 2010s a lot of the industry's returns came from cheap debt and rising multiples. With both less available, the operational lever is where the differentiation now has to come from, and every fund will say this in its fundraising deck.

   Where candidates lose it

   Answering only 'leverage'. Leverage amplifies returns, it does not create them, and a sponsor interviewer will push back hard. Name the operational and governance levers and acknowledge that the easy financial tailwinds have gone.

   Expect next

   • Which lever matters most today?
   • What would you do in the first hundred days?
   • What is better, a dollar of EBITDA or a dollar less debt?

2. 003What is better: a one dollar increase in EBITDA or a one dollar decrease in debt?Value creationIntermediatetechnicalAMAres ManagementPrivate Equity · New York · 2026

   Say this

   A dollar of EBITDA, by the exit multiple. If you exit at 10 times, one extra dollar of EBITDA is ten dollars of enterprise value, while a dollar of debt repaid is one dollar of equity. Ten to one.

   Then walk it

   1. Debt paydown is a one-for-one transfer: a dollar less debt is a dollar more equity at exit.
   2. EBITDA is capitalised at the exit multiple. At 10 times, a permanent extra dollar of EBITDA adds ten dollars of enterprise value and therefore ten dollars of equity.
   3. So the ratio is simply the exit multiple, which is a clean way to say it and shows you understand the mechanism rather than the answer.
   4. The conditions that matter: the EBITDA has to be recurring, not a one-off, and the multiple has to hold. A dollar of EBITDA from a one-time contract is worth roughly a dollar, not ten.
   5. There is also a second-order benefit: higher EBITDA reduces the leverage ratio at the same debt level, which improves covenant headroom and refinancing options.
   6. The nuance worth adding: early in a hold, when leverage is high and covenants are tight, a dollar of debt repayment can be worth more than its face value because it buys flexibility and avoids a default. So the answer is EBITDA in general, debt paydown when survival is the issue.

   Where candidates lose it

   Answering without naming the exit multiple as the exchange rate. That one insight is the whole question. Also missing that the EBITDA must be recurring for the multiple to apply.

   Expect next

   • What if the EBITDA is a one-off?
   • When would you prefer the debt repayment?
   • How does that change how you prioritise the value creation plan?

3. 025What are the key drivers of value creation in a deal, and how do you attribute the return?Value creationIntermediatetechnicalTPTPGInvestment Banking · New York · 2024

   Say this

   Break the equity gain into revenue growth, margin improvement, multiple change and deleveraging. The attribution bridge is a standard exhibit in every exit review and every fundraising deck.

   Then walk it

   1. Start with entry and exit equity values, then decompose the change.
   2. Revenue growth contribution: hold margin and multiple constant, and measure the EBITDA change from volume and price alone.
   3. Margin contribution: hold revenue constant and measure the EBITDA change from margin improvement. Splitting these two matters because they say different things about the quality of the work.
   4. Multiple contribution: change in exit multiple times exit EBITDA. This is the component the fund does not control and the one limited partners discount.
   5. Deleveraging contribution: the reduction in net debt over the hold, which flows straight to equity.
   6. The interpretation is what matters: a fund whose returns come predominantly from multiple expansion has been lucky and will say it was skill. A fund whose returns come from margin and revenue has actually done something. In a fundraising conversation, that attribution is the single most scrutinised chart.

   Where candidates lose it

   Naming the drivers but being unable to build the bridge. Also failing to separate revenue from margin, which collapses the two very different value creation stories into one.

   Expect next

   • Which component would a limited partner discount?
   • How would you build that bridge in Excel?
   • Which driver has been most important for the industry over the last decade?

4. 026What is multiple arbitrage and how does a buy-and-build strategy work?Value creationIntermediatetechnicalAudax GroupPrivate Equity · Boston · 2021

   Say this

   Buy small companies at low multiples into a platform that is valued at a higher multiple. Six times EBITDA bought inside a business worth twelve times creates value on completion, before any synergy.

   Then walk it

   1. The mechanism: smaller companies trade at lower multiples because they are riskier, less liquid and have fewer buyers. A larger platform trades higher. Moving EBITDA from one to the other closes that gap.
   2. So acquiring a business at six times that is immediately valued at your platform's twelve times doubles the value of that EBITDA with no operational change at all.
   3. Add cost synergies on top, removing duplicated overhead, and the effective entry multiple falls further, often to four or five times post-synergy.
   4. The strategy also grows the platform, and scale itself can support a higher exit multiple by improving diversification, management depth and buyer appeal.
   5. The risks are real and worth naming: integration capacity, paying up as a sector gets competitive, and roll-ups that grow EBITDA while destroying organic growth. A buyer at exit will look hard at organic performance excluding acquisitions.
   6. And the financing constraint: each acquisition needs funding, so the platform's leverage and lender relationships determine how fast you can execute.

   Where candidates lose it

   Describing the arbitrage as if it were free money. The exit buyer sees through a roll-up with no organic growth, and diligence at exit will strip out acquired growth. Naming that shows you understand both ends of the trade.

   Expect next

   • What does a buyer at exit look at in a roll-up?
   • How do you fund a bolt-on programme?
   • How much of the synergy would you pay away?

5. 061How do you think about a roll-up in a fragmented industry?Value creationHardsuperdayAudax GroupPrivate Equity · Boston · 2021

   Say this

   The arithmetic works easily and the execution usually does not. The test is whether the combined entity is genuinely worth more than the sum of the parts, or whether you have just assembled a portfolio of small businesses with a head office on top.

   Then walk it

   1. The value creation is real when there is genuine scale benefit: procurement leverage, shared infrastructure, a single back office, cross-selling, or density in a route-based business where overlapping territories cut cost per job.
   2. It is illusory when the acquired businesses keep operating exactly as before. Then all you have is multiple arbitrage and added overhead, and the exit buyer will see it.
   3. Integration capacity is the binding constraint. Most roll-ups fail because they acquire faster than they can integrate. A platform that closes eight deals a year with a two-person integration team will have problems in year three.
   4. Watch organic growth separately. A buyer at exit will strip out acquired revenue and look at the organic trend. A roll-up growing 30 percent with minus 2 percent organic is worth much less than the headline.
   5. Price discipline erodes over time: the first deals are cheap, then sellers learn what you are doing and the sector gets competitive. Having a walk-away multiple and holding it is what separates good platforms.
   6. And funding: each deal needs capital, so the platform's leverage capacity and lender relationships set the pace. A roll-up that runs out of debt capacity mid-strategy is stuck.

   Where candidates lose it

   Focusing only on the multiple arbitrage. It is the easy half. Integration capacity and organic growth are what determine whether the exit buyer pays the platform multiple, and naming those is what makes the answer credible.

   Expect next

   • How would you measure whether integration is working?
   • What would you do if organic growth went negative?
   • How do you keep discipline on price as the sector heats up?
