What EnerSys does
EnerSys is a global manufacturer of stored energy solutions for industrial applications, headquartered in Reading, Pennsylvania and listed on the NYSE under ticker ENS. The company designs and produces batteries across multiple chemistries — Thin Plate Pure Lead (TPPL), lithium-ion, AGM, and flooded lead-acid — alongside battery chargers and integrated power systems including UPS, enclosures, and DC power equipment. EnerSys serves over 10,000 customers in more than 100 countries across data centers, material handling and logistics, telecommunications, defense and aerospace (including space-qualified batteries powering NASA missions), transportation, medical, and industrial power. The portfolio spans proprietary brands (NexSys, DataSafe, Hawker, Odyssey, PowerSafe, Genesis) and acquired brands (Alpha, Bren-Tronics, NorthStar, Quallion, ABSL, Purcell), unified by shared TPPL and lithium technology platforms.
The business operates across three operating segments (effective Q1 FY2027): Network & Infrastructure Solutions, Industrial Mobility Solutions, and Precision Power Solutions. Revenue is generated primarily through hardware sales of batteries, chargers, and integrated power systems, supplemented by aftermarket services (installation, commissioning, maintenance) and a recurring IRA Section 45X advanced manufacturing tax credit contributing approximately $40 million per quarter. Distribution combines a direct enterprise sales force, independent representatives, and a global distributor network, with large multi-year contracts in defense (notably $75M and $92M US Navy TPPL awards) as anchors alongside diversified mid-market and SMB volume.
EnerSys is executing an active strategic reset under CEO Shawn O'Connell and CFO Andrea Funk, branded as "EnerGize," which emphasizes cost discipline, segment realignment, and a pivot toward higher-value niches including AI-driven data center power (DataSafe Noir), defense electrification, and domestic lithium manufacturing via a planned Greenville, South Carolina gigafactory supported by a $199 million DOE award under negotiation. FY2026 (ended March 31, 2026) delivered record revenue of $3.75 billion and adjusted diluted EPS of $10.56, with operating cash flow of $548 million and $409 million returned to shareholders, against net leverage of 1.1-1.2x EBITDA.
