1. 011Give me a purchase price for this company, given that the acquisition will generate an extra million of EBITDA.ValuationHardtechnicalAudax GroupPrivate Equity · Boston · 2021

   Say this

   Price the standalone business on its own multiple, then decide how much of the synergy you are willing to hand to the seller. In a buy-and-build you want to pay for the asset as it is and keep the synergy for yourself.

   Then walk it

   1. Start with standalone value: the target's own EBITDA at a multiple appropriate to its size and quality. Small bolt-ons trade well below platform multiples, often six to eight times against twelve for the platform.
   2. Then the synergy. That extra million of EBITDA, capitalised at your platform's exit multiple, is worth ten or twelve million of enterprise value to you.
   3. The negotiation is about how much of that you concede. A disciplined buyer pays little or nothing for synergies it creates; a competitive auction forces you to share some of it.
   4. So I would express it as a range: I would open at the standalone multiple, and my walk-away is the price at which the deal stops clearing my return hurdle after synergies.
   5. Then check the maths on the multiple arbitrage: buying at seven times and having it valued at twelve inside the platform creates value immediately, and that arbitrage is the core of any buy-and-build.
   6. And I would probability-weight the synergy. Cost synergies in a bolt-on are largely deliverable; revenue synergies rarely are, so I would underwrite only the former.

   Where candidates lose it

   Adding the synergy to the target's EBITDA and paying a full multiple on the combined figure. That hands the entire value creation to the seller before you have done any work, and it is the error the question is designed to find.

   Expect next

   • How much of the synergy would you pay away in a competitive auction?
   • What is multiple arbitrage?
   • How do you underwrite synergies in diligence?

2. 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?

3. 046How would you diligence a founder-run business?Due diligenceHardsuperdayAudax GroupPrivate Equity · Boston · 2021HIH.I.G. CapitalPrivate Equity · Paris · 2024

   Say this

   Assume the reporting is weaker than it looks and the founder is more central than anyone admits. The two questions are what the real earnings are, and what happens to the business when the founder steps back.

   Then walk it

   1. Financial reporting is usually thin. There may be no audited accounts, no management accounts by segment, no unit-level profitability. Budget more time and money for quality of earnings than you would for a corporate carve-out.
   2. Personal expenses run through the business are standard: cars, travel, family on the payroll, property. These are legitimate add-backs but each needs verification, and they are also a signal about controls.
   3. Founder dependency is the core risk. Which customer relationships are personal? Who actually makes pricing decisions? Is there a second layer of management, or does everything route through one person?
   4. Test it concretely: ask what happened when the founder took a long holiday. Ask the customers who they call. The answers are usually revealing.
   5. Related-party arrangements: property leased from a founder-owned entity, supply from a family business, loans in both directions. All need to be put on arm's-length terms before closing.
   6. Then structure around what you find. Rollover equity and an earnout keep the founder engaged; a transition agreement with defined handover milestones; and building the second layer of management is usually the first hundred days priority.

   Where candidates lose it

   Treating it like a corporate diligence. The distinctive risks are informal reporting, personal expenses and founder dependency, and the answer should end with how you structure around them rather than just listing them.

   Expect next

   • How would you structure the founder's rollover?
   • What if the founder wants to leave immediately?
   • How do you value a business where the owner works unpaid?

4. 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?

5. 079What are the transaction multiples on the deals on your resume?Career and fitIntermediateevery roundWPWarburg PincusPrivate Equity · New York · 2014Carlyle GroupAsset Management · Washington · 2015Audax GroupLeveraged Buyouts · New York · 2025

   Say this

   Know every number on your resume cold: enterprise value, the entry multiple on both EBITDA and revenue, leverage, the growth rate, the margin, and roughly what returns the structure implied. Not knowing them is disqualifying.

   Then walk it

   1. For each deal listed, be able to state without hesitation: enterprise value, EV/EBITDA, EV/revenue if relevant, leverage as a multiple of EBITDA, and the premium if it was public.
   2. Then the operating numbers: revenue, growth rate, EBITDA margin, and the direction each has been moving.
   3. Then your view: was the multiple justified against the comparable set, and what did the buyer need to believe?
   4. For confidential deals, give the numbers in ranges or as multiples rather than absolute figures if the specifics are not public. Saying 'I can talk about it on a multiples basis because the absolute figures are not public' is the professional answer and interviewers respect it.
   5. Audax explicitly asks candidates to describe something small on their resume, which is the same test in another form: everything on the page is fair game, including the line you thought nobody would ask about.
   6. So the preparation rule is simple: if you cannot discuss a line on your resume for five minutes, take it off the resume.

   Where candidates lose it

   Putting a deal on your resume you cannot discuss in detail. Sponsors interview by going deep on one transaction, and a candidate who worked on the periphery and cannot answer basic questions is immediately exposed.

   Expect next

   • Would you have done the deal?
   • Who else was in the process?
   • Describe something small on your resume.

6. 087How would you model a bolt-on acquisition inside an existing platform?LBO mechanicsHardtechnicalAudax GroupPrivate Equity · Boston · 2021

   Say this

   Add the target's EBITDA and synergies to the platform, fund it with incremental debt and any equity top-up, then check the pro forma leverage against the credit agreement and the effect on the sponsor's equity return.

   Then walk it

   1. Start with sources and uses for the bolt-on: purchase price at the target's multiple, fees, funded by incremental term loan, revolver drawing, or a sponsor equity contribution.
   2. Add the target's EBITDA plus realisable cost synergies to the platform's consolidated EBITDA. Be conservative on synergies and phase them over 12 to 24 months rather than assuming day-one delivery.
   3. Check pro forma leverage immediately. The credit agreement will have a permitted acquisitions basket and an incurrence test, usually requiring leverage to be no worse than before or below a defined level. If the deal breaches it you need lender consent.
   4. The accretion test: because you buy at six times and the platform is valued at twelve, the deal is immediately value-accretive on a multiple basis. Show that arbitrage explicitly, since it is the core of the strategy.
   5. Then the return effect: model the exit with the enlarged EBITDA at the platform multiple and compare the sponsor IRR with and without the bolt-on. If the sponsor has to fund equity, the timing of that cheque matters for IRR.
   6. And model the integration cost as real cash, because it always is, and it is the line most often omitted.

   Where candidates lose it

   Assuming synergies arrive immediately and forgetting integration costs. Also ignoring the credit agreement: many bolt-ons are constrained not by economics but by what the existing documentation permits.

   Expect next

   • What is a permitted acquisitions basket?
   • How do you phase the synergies?
   • What if it breaches the leverage test?
