The case tests the ability to identify revenue and cost synergies from cross-selling to an existing customer base, perform financial modeling with straightforward inputs, and recognize risks in entering a commoditized, mature market with high competition and regulatory complexity.

Okay Mobile, an Australian MVNO with 1M mobile subscribers, is considering entering the energy retail market as a virtual retailer. The task is to assess the viability of this expansion and project profitability. Analysis reveals $10M in potential profits (exceeding the $5M target) through 0.2M customers by year-end, supported by cross-selling synergies, but faces operational and competitive risks in a mature, low-margin commodity market.

Key Insights:

  1. Revenue synergies: Cross-selling to existing 1M subscriber base reduces customer acquisition costs and enables bundled offerings (one-stop shop value proposition)
  2. Cost synergies: Shared IT infrastructure, unified customer platforms, and leverage of existing customer service teams reduce marginal costs
  3. Financial model: $10M profit = (0.1M avg customers × $2,000 annual spend × 10% commission) - $10M fixed costs; profit margin of 5% is reasonable for commoditized energy market
  4. Key risks: Market consolidation and aggressive competition; operational complexity in managing multiple energy provider relationships; potential underestimation of IT and customer service costs; ambitious 0.2M customer target may require expensive marketing
