Buying a Marketplace Brand Portfolio / Aggregator business

Published · Reviewed by The Diligence Standard Team · Updated

Portfolio revenue can mask weak brand-level economics, duplicated overhead, stale inventory and concentration on the same platform or supplier base. Diligence should rebuild each brand before accepting consolidated EBITDA.

How the business works

A portfolio aggregator is only as strong as its consolidated contribution margin, brand-level concentration, inventory, shared overhead, platform exposure, acquisition accounting and the operational synergies that actually exist.

Risks to test

  • Consolidated EBITDA hides weak brands
  • Same platform risk across portfolio
  • Acquisition add-backs are aggressive
  • Inventory overhang
  • Shared overhead is misallocated
  • Supplier concentration crosses brands
  • Integration systems/key managers are fragile

Evidence to request and reconcile

  • Brand-level P&Ls
  • Acquisition/earnout schedules
  • Inventory by brand
  • Platform/channel reports
  • Shared payroll/overhead
  • Supplier spend
  • IP/trademark portfolio
  • Central operating KPIs

Decision questions

  • Which brands create most EBITDA?
  • What brands would be unprofitable standalone?
  • How much platform risk is actually diversified?
  • What overhead is required after closing?
  • What inventory is impaired?
  • Which supplier exposures repeat across brands?
  • What acquisition liabilities remain?
  • Can central operations run without founder?
