Custom Truck One Source Inc

Custom Truck One Source, Inc. ("we," "our," "us," "Custom Truck," or "the Company"), a Delaware corporation, and its wholly owned subsidiaries are engaged in the business of providing a range of services and products to customers through rentals and sales of specialty equipment, rentals and sales of aftermarket parts and services related to the specialty equipment, and repair, maintenance, and customization services related to that equipment. Immediately following the acquisition by Nesco Holdings II, Inc. of Custom Truck One Source, L.P. ("Custom Truck LP") on April 1, 2021 (the "Acquisition"), Nesco Holdings, Inc. ("Nesco Holdings") changed its name to "Custom Truck One Source, Inc." and changed The New York Stock Exchange ticker for its shares of common stock from "NSCO" to "CTOS."

We are a specialty equipment provider to the electric utility transmission and distribution, telecommunications, rail, forestry, waste management and other infrastructure-related industries in North America. Our core business relates to our new equipment inventory and rental fleet of specialty equipment that is utilized by service providers in infrastructure development and improvement work. We offer our specialized equipment to a diverse customer base, including utilities and contractors, for the maintenance, repair, upgrade, and installation of critical infrastructure assets, including distribution and transmission electric lines, telecommunications networks, and rail systems, as well as for lighting and signage. We rent, produce, sell, and service a broad range of new and used equipment, including bucket trucks, digger derricks, dump trucks, cranes, service trucks, and heavy-haul trailers. Through December 31, 2025, we managed our business in our three reporting segments: Equipment Rental Solutions ("ERS"), Truck and Equipment Sales ("TES"), and Aftermarket Parts and Services ("APS"). Recently, our Chief Executive Officer reevaluated how he assesses performance and allocates resources across our business. This review resulted in a change in the reporting of management’s internal financial information. As a result, beginning in the three months ending March 31, 2026, we will report our results under two reportable segments: (1) Specialty Equipment Rentals ("SER") and (2) Specialty Truck Equipment and Manufacturing ("STEM"). Upon implementation, the new SER segment will consist of our historical ERS segment and a portion of our historical APS segment, and the new STEM segment will consist of our historical TES segment and a portion of our historical APS segment. We will also begin reflecting intercompany activity between the two segments, which will ultimately be eliminated in consolidation. This new segment reporting reflects how CTOS’s business is managed and how resources are allocated in 2026, and management believes this new presentation better reflects the positioning of CTOS’s strategies and operations portfolio. Management expects to provide more information on the new two segments in early April. We believe our new segment realignment will better reflect key economic drivers, capital intensity, and margin profiles of the respective new segments, as well as align our external reporting with how management allocates capital and evaluates performance.

We operate with a differentiated "one-stop-shop" business model, offering equipment rental, new and used equipment sales, and aftermarket parts and service out of more than 40 locations across the U.S. and Canada. Customers receive additional support throughout the country from Custom Truck’s twenty-four hour, seven-day a week ("24/7") call center, approximately 90 mobile technicians, and over 2,600 third-party service partners. Custom Truck and its customers also benefit from its sophisticated sourcing model and large-scale integrated production and customization capabilities, which enhance the quality and diversity of its equipment offerings, reduce both cost and lead times for equipment sales and provide greater flexibility to optimize its rental fleet. These attributes, together with a strong reputation built over many years, position Custom Truck to capitalize on attractive secular growth trends across its end-markets.

Custom Truck owns one of the industry’s largest fleets of specialty rental equipment focused on electric utility transmission and distribution ("T&D"), infrastructure, rail and telecommunications end-markets through our ERS segment. As of December 31, 2025, our fleet is comprised of more than 10,400 units with an average unit age of approximately 2.9 years, which we believe is young by rental fleet standards and compares favorably to the long useful life of the equipment. Our rental fleet is managed on a national level, which allows us to efficiently reposition equipment in response to shifts in regional demand and thereby sustain strong utilization levels.
