EnerSys,

Item 8.01 Other Events. On July 23, 2026, as part of a strategic review, EnerSys revised the scope of its previously announced planned lithium-ion cell manufacturing facility in Greenville, South Carolina. EnerSys now expects the planned facility to have an initial capacity of up to 1 gigawatt-hour, as compared to approximately 4 to 5 gigawatt-hours as originally planned, and a materially smaller physical footprint, with such changes made to better align on the aerospace and defense markets as well as specialized industrial applications where a secure supply chain is essential. Additionally, EnerSys has been awarded a revised grant from the U.S. Department of Energy (“DOE”) of approximately $150 million, subject to final documentation and other customary conditions as well as up to $200 million of state and local incentives. EnerSys currently estimates the total net investment for the planned facility to be approximately $500 million. Under the updated plan, EnerSys expects the facility to have initial production capacity of approximately 1 gigawatt‑hour, purpose‑built to meet the specialized requirements of defense applications. EnerSys intends to use federal, state, and local funding, and operating cash flow to support the capital requirements of the factory. EnerSys’ Board of Directors has formally approved the investment and development plan. EnerSys currently anticipates beginning construction in the first half of fiscal year 2028, subject to customary approvals and conditions, including, but not limited to, agreement on a revised award from the DOE, with full production expected approximately three years following the commencement of construction. A press release regarding the planned facility is attached as Exhibit 99.1 to this Current Report on Form 8-K.

Item 7.01 Regulation FD Disclosure. EnerSys previously issued a press release on June 14, 2023 announcing that it had entered into a non-binding memorandum of understanding with Verkor SAS, to explore the development of a lithium battery gigafactory in the United States. EnerSys intends to transition away from its technology relationship with Verkor and does not expect Verkor to serve as the project’s technology partner going forward.
