McGrath RentCorp is a diversified business-to-business rental company with three primary operating divisions: relocatable modular buildings, portable storage containers, and electronic test equipment, along with a classroom manufacturing business. The company generates revenue through equipment rentals and direct sales, with rental operations accounting for the majority of revenues through long-term operating leases and associated rental services such as delivery, installation, and maintenance. Its customers include public schools, government agencies, electronics manufacturers, and commercial entities across the United States and Canada. The capital-intensive rental business model relies on a large installed fleet of equipment and customers, with profitability driven by spreading fixed costs across recurring rental revenues and leveraging shared facilities and operating systems across divisions.
