McGrath RentCorp is a diversified business-to-business rental company operating in the United States and Canada. The Company provides relocatable modular buildings, portable storage containers, and electronic test equipment for rent and sale. Its primary emphasis is on equipment rentals, although sales occur in the normal course of business. McGrath RentCorp serves customers across various industries including education, construction, healthcare, aerospace, defense, and manufacturing. The Company invests capital in rental products and recovers its original investment through rents over a period shorter than the product’s useful life. When rental equipment is sold, a significant portion of the original investment is typically recovered. This business model supports operating cash flows that fund continued rental asset growth.
McGrath RentCorp generates revenue primarily from the rental and sale of its three core product lines: modular buildings, portable storage containers, and electronic test equipment. Rental revenue is derived from monthly lease agreements with terms typically ranging from one month to several years, depending on the product type. Sales revenue comes from the disposition of rental inventory or new equipment sold to meet permanent customer needs. The Company serves a broad customer base that includes public and private schools, colleges, universities, construction firms, healthcare providers, governmental agencies, and industrial companies. Revenue is also influenced by seasonal demand patterns, particularly in the educational and construction sectors. The Company’s rental products are designed for long useful lives relative to typical rental terms, enabling high utilization and residual value upon sale. Effective asset management, including repair, maintenance, and refurbishment programs, supports equipment longevity and financial performance.
The company operates through the following segments: Mobile Modular, Portable Storage, TRS-RenTelco, and Enviroplex.
- Mobile Modular: This segment provides relocatable modular buildings for use as classrooms, temporary offices, healthcare facilities, and other purposes. Mobile Modular purchases new modular units from manufacturers based on its design specifications and maintains a rental fleet of over 41,000 units. The segment emphasizes customer service, rapid delivery, and in-house customization to meet project needs. Mobile Modular markets its units through its website at www.mobilemodular.com, internet advertising, and direct marketing. The Company believes Mobile Modular has a leading modular building fleet in the United States, particularly in California, Florida, and Texas for educational space needs.
- Portable Storage: This segment rents and sells steel storage and office containers for temporary storage solutions. Portable Storage’s inventory includes ISO-certified shipping containers and modified ground level offices (GLOs) made from weather-resistant corrugated steel. The segment serves customers in construction, retail, commercial, industrial, energy, petrochemical, manufacturing, education, and healthcare sectors. Portable Storage emphasizes product availability, quality, price, and service to compete in a highly competitive market. The Company believes Portable Storage is one of the largest participants in the temporary portable storage rental industry in North America with a national reach across multiple regions.
- TRS-RenTelco: This segment rents and sells electronic test equipment including general purpose and communications test equipment from facilities in Texas and Canada. TRS-RenTelco’s inventory includes oscilloscopes, analyzers, signal sources, and network test equipment used by customers in aerospace, defense, communications, manufacturing, and semiconductor industries. The segment is supported by an ISO 9001-2015 registered calibration laboratory that ensures equipment is calibrated and ready for immediate shipment. TRS-RenTelco attracts customers through its website at www. TRSRenTelco.com, outside sales force, telemarketing, trade shows, and electronic mail campaigns. The Company believes TRS-RenTelco is one of the largest electronic test equipment rental and leasing companies in North America offering a broad and deep selection of equipment for rent.
- Enviroplex: This segment manufactures and sells portable classrooms built to the requirements of the California Division of the State Architect. Enviroplex sells directly to California public school districts and other educational institutions for use as permanent or temporary classroom space. The segment focuses on the California market, where demand is driven by shifting student populations, insufficient funding for new construction, and modernization of aging school facilities. Enviroplex complements Mobile Modular’s rental offerings by providing sale options for modular classrooms. The Company does not list specific trademarked product names under this segment beyond its corporate name.
McGrath RentCorp maintains a strong position within each of its rental industries through a combination of operational scale, asset management expertise, and customer-focused service. Mobile Modular competes against national and regional modular building providers, leveraging its regional sales and inventory centers to reduce costs and improve response times. Portable Storage faces competition from larger national firms and local operators, differentiating itself through fleet quality and responsiveness. TRS-RenTelco operates in a fragmented market with no dominant player, competing on equipment availability, technical expertise, and 24/7 customer support. The Company’s competitive advantages include its decentralized yet integrated operating structure, long product life cycles, and ability to recover high percentages of original investment through rentals and sales. Management believes its emphasis on preventive maintenance and refurbishment enhances equipment resale value and rental rate stability over time.
McGrath RentCorp serves a diverse customer base across multiple industries. In the modular building segment, customers include public and private schools, colleges, universities, construction companies, healthcare providers, and governmental agencies needing temporary administrative or operational space. Portable Storage serves construction sites, retail businesses, industrial facilities, and educational institutions requiring secure, temporary storage solutions. TRS-RenTelco’s customers span aerospace, defense, communications, manufacturing, and semiconductor companies, including Fortune 500 firms and smaller market businesses requiring test equipment for research, development, and infrastructure projects. Enviroplex sells specifically to California public school districts and other educational institutions within the state. While the filing does not disclose specific customer names by segment, it indicates that educational space needs represent a significant portion of modular rental and sales revenues, particularly in California, Florida, Georgia, Louisiana, Maryland, North Carolina, South Carolina, Texas, Virginia, and Washington, D.
