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. 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?
