EnerSys manufactures and sells industrial batteries and energy storage systems for infrastructure and industrial applications. EnerSys operates through four segments: Energy Systems, Motive Power, Specialty, and New Ventures. Energy Systems provides backup power and management for data centers, telecom, and utilities to maintain critical infrastructure during grid fluctuations. Motive Power supplies batteries and chargers for electric forklifts and industrial vehicles. The Specialty segment produces batteries for aerospace, defense, and transportation. New Ventures develops battery energy storage systems for commercial buildings and EV fast charging. EnerSys generates revenue by selling these products and power electronics, benefiting from recurring revenue via battery replacement cycles. Profitability depends on manufacturing volume and a shift toward higher-value, maintenance-free thin plate pure lead technology. The company's growth strategy focuses on expanding into lithium-ion UPS systems for data centers, increasing its defense footprint through M&A, and developing a domestic lithium cell factory. EnerSys also utilizes advanced manufacturing tax credits to support its U.S. production. EnerSys distributes its products through a mix of direct sales, owned service locations, and independent distributors.
