1. 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.

   • 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?

2. 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?
