What National Maintenance Services does

National Maintenance Services operates as Concentric, a privately held US industrial power services provider headquartered in Carrollton, Texas and operating as a division of Mitsubishi Heavy Industries Ltd. (MHI) under the OnPoint Group umbrella. The company delivers nationwide forklift power management, critical power infrastructure, dedicated on-site maintenance, and energy storage solutions to enterprise customers across manufacturing, warehousing, cold storage, data centers, utilities, communications, and industrial/petrochemical verticals.

Concentric's core technology platform centers on PowerHIVE, a proprietary autonomous forklift battery swap system that completes battery reloads in approximately two minutes and has executed over 250,000 swaps across 200+ facilities. The platform is supported by the RAAMS IoT-enabled remote monitoring system, the GuaranteedPOWER managed service program, the ConcentricCARE proactive maintenance program, and a critical power portfolio spanning BESS (1-15MW typical capacity), microgrids, distributed energy resource management, and virtual power plant enablement. The company has grown through an aggressive acquisition strategy, completing 14 acquisitions between August 2021 and January 2026 to build out its national footprint.

The business model combines recurring managed service subscriptions (GuaranteedPOWER at fixed monthly fees over 3-6 year contracts with 98% retention), direct equipment sales of batteries, chargers, UPS systems, and energy storage hardware, and on-site professional services delivered through 200+ dedicated technicians across 60+ stocking locations. Customers include named enterprise accounts such as Rockline Industries, CBRE, ATMC, Smithfield Foods, and United Distributors. Pricing is quote-based and not publicly disclosed; additional recurring revenue streams include Clean Fuels Program credits in Oregon, Washington, and California, and a Demand Response grid management program.

Broad incumbents

• ABB Ltd: Global leader in electrification, motion, and automation products including UPS, switchgear, and industrial power systems. Comparable to Concentric's critical power and switchgear service capabilities, particularly in utility and data center end markets.
• ABM Industries: Facility services, parking, and transportation solutions provider serving commercial, industrial, and healthcare customers nationwide. Comparable business model to Concentric's multi-site managed services concept, though focused on janitorial and integrated facility services rather than industrial power.
• Generac Holdings: Leading manufacturer of backup power generators and energy storage systems for residential, commercial, and industrial customers. Comparable to Concentric's critical power/generator and BESS offerings but with a much broader product portfolio and consumer focus.
• Schneider Electric: Global specialist in energy management and automation, including UPS systems, switchgear, and data center infrastructure (APC, Galaxy). Overlaps with Concentric's Critical Power Division but operates at significantly larger scale with broader portfolio.
• EMCOR Group: Provider of electrical and mechanical construction, industrial and facility services including HVAC, lighting, and power distribution. Comparable to Concentric's Mechanical & HVAC and On-Site Maintenance service offerings at a much larger scale with broader end-market exposure.

Direct peers

• Vertiv Holdings: Provider of critical digital infrastructure and continuity solutions including UPS, thermal management, and power management for data centers. Comparable to Concentric's Critical Power and Mission Critical & Data Center Power offerings, including the recent CCI acquisition scope.
• East Penn Manufacturing: Privately held manufacturer of industrial and motive power batteries (MK Battery, Deka). Direct peer in the lead-acid and lithium forklift battery supply and service ecosystem that Concentric operates within.
• EnerSys: Global manufacturer of industrial motive power batteries (including Hawker brand) and reserve power products. Most direct upstream peer to Concentric's forklift battery and stationary power service business, and a recognized Concentric supplier (EnerSys Representative of the Year award).

Others

• Crown Equipment Corporation: Privately held global forklift OEM with broad material handling portfolio. Concentric's motive power services support Crown lift truck fleets across the US, making Crown an adjacent peer in the material handling ecosystem rather than a direct competitor.

Emerging players

• Flow-Rite Controls: Manufacturer of battery watering systems, spill containment, and maintenance products for industrial batteries. Comparable to Concentric's ConcentricCARE and Environmental & Safety Products lines with overlapping battery maintenance use cases but a narrower product focus.
