EnerSys filings document the formal disclosures of an industrial stored-energy manufacturer whose common stock trades on the New York Stock Exchange under ENS. Current reports furnish quarterly operating results, dividend actions, share repurchase authorization, annual meeting voting outcomes and material agreements tied to credit facilities and receivables financing.
The filing record also covers restructuring and exit-cost disclosures for workforce and manufacturing actions, including impairment and disposal-cost items related to battery production facilities.

EnerSys is refining its planned lithium-ion cell manufacturing facility in Greenville, South Carolina, shifting to a defense‑ and aerospace‑focused strategy. The company now expects initial production capacity of approximately 1 gigawatt‑hour, down from the originally planned approximately 4 to 5 gigawatt‑hours, with a materially smaller physical footprint tailored to specialized industrial and defense applications requiring a secure U.S. supply chain.
EnerSys has been awarded a revised U.S. Department of Energy grant of about $150 million, subject to final documentation and customary conditions, and has an incentive package from South Carolina and Greenville County valued at up to $200 million. The company currently estimates total net investment for the facility at approximately $500 million and intends to fund it with federal, state and local support and operating cash flow. The Board of Directors has formally approved the investment and development plan. EnerSys currently anticipates beginning construction in the first half of fiscal 2028, with full production expected about three years after construction begins, and plans to transition away from its technology relationship with Verkor SAS in favor of established aerospace and defense technology partners.
