McGrath RentCorp operates a specialized rental business across three segments: modular buildings (portable classrooms, offices, storage), electronic test equipment (oscilloscopes, spectrum analyzers for semiconductor/aerospace), and portable storage containers. The company owns a fleet of ~9,000 modular buildings concentrated in California and Texas education markets, plus ~$400M in electronic test assets serving R&D and manufacturing customers. Strong returns (26.8% operating margin, 11.6% FCF yield) reflect asset ownership economics and sticky customer relationships in niche markets.

Incremental margins are strong when existing fleet capacity is deployed (minimal marginal cost), but growth requires ongoing capex to expand fleet. Typical capex runs 40-50% of operating cash flow to maintain and grow the rental base.
