Let’s assume our client is Great Burger (GB) a fast food chain that competes head–to–head with McDonald’s, Wendy’s, Burger King, KFC, etc. GB is the fourth largest fast food chain worldwide, measured by the number of stores in operation. As most of its competitors do, GB offers food and “combos” for the three largest meal occasions: breakfast, lunch and dinner. Even though GB owns some of its stores, it operates under the franchising business model with 85% of its stores owned by franchisees (individuals own & manage stores and pay a franchise fee to GB, but major business decisions e.g. menu, look of store, are controlled by GB). As part of its growth strategy GB has analyzed some potential acquisition targets including Heavenly Donuts (HD), a growing doughnut producer with both a US and international store presence. HD operates under the franchising business model too, though a little bit differently than GB. While GB franchises restaurants, HD franchises areas or regions in which the franchisee is required to open a certain number of stores. GB’s CEO has hired McKinsey to advise him on whether they should acquire HD or not.

Great Burger seeks McKinsey advice on acquiring Heavenly Donuts. The case requires evaluating HD’s standalone value, identifying revenue and cost synergies, calculating the financial impact of selling doughnuts in GB stores while accounting for cannibalization, and ultimately determining whether the acquisition creates sufficient value.

Key Insights:

  1. Synergy identification in M&A requires analyzing both revenue opportunities (cross-selling, geographic expansion, superior site selection) and cost savings (SG&A integration, purchasing scale, real estate expertise)
  2. Cannibalization analysis is critical when combining complementary products—the 10% cannibalization rate in this case reduces the apparent $60K revenue contribution to $15K net incremental profit per store
  3. Different franchise structures between companies require integration planning to maintain system coherence while preserving each brand’s operational model
  4. Quantitative rigor at each step allows early-stage hypothesis validation (e.g., requiring $1.2M sales/store in 5 years is achievable given consumption growth doubling)
