This case tests market sizing, growth strategy analysis, and creative problem-solving within a private equity context. The candidate must build a bottoms-up growth model, identify realistic revenue drivers, and recognize that achieving 30% growth requires multiple initiatives beyond operational improvements. The case effectively combines quantitative analysis (market sizing, revenue calculations) with strategic thinking (geographic expansion, new products).

The client is a private equity firm looking to acquire a chain of car washes in the United States.

A PE firm seeks to acquire a 200-location car wash chain generating $40M in annual revenue. To justify the acquisition, the firm needs to demonstrate 30% revenue growth (to $52M) within one year. The case requires candidates to identify feasible growth levers through new products (vacuums, waxing), geographic expansion, and pricing strategies, ultimately showing that approximately 25% growth is achievable through service additions.

Key Insights:

  1. Market sizing is foundational: The total US car wash market is ~$16.5B, indicating significant room for growth beyond the $40M current revenue
  2. Growth can come from multiple vectors: existing locations (new services, price increases, marketing), new locations (existing/new markets), and geographic expansion into underserved regions
  3. Customer segmentation matters: Low-frequency and high-frequency customers have different willingness-to-pay for ancillary services (wax), affecting revenue potential
  4. The company holds strong competitive positions in 10 of 14 markets but is completely absent from Midwest, Mid-Atlantic, Northeast, and Southwest regions—representing expansion opportunities
  5. Adding high-margin ancillary services (vacuums at $0.50 and waxing at $1) generates approximately 15% incremental revenue, leaving a 5% gap requiring additional strategic initiatives
