EnerSys has refined its Greenville, South Carolina, lithium‑ion plant plan to prioritize defense and aerospace applications, scaling initial capacity to about 1 gigawatt‑hour and narrowing the footprint to bolster a secure, U.S.–based supply chain. The project is supported by roughly $150 million in U.S. Department of Energy funding and about $200 million in state and local incentives, with total net investment now estimated at $500 million. EnerSys will exit its technology relationship with Verkor SAS for this venture and rely on its aerospace and defense supplier network. The company’s board has approved the updated investment and construction is expected to begin in early fiscal year 2028, with full production roughly three years after construction starts. An insider buy was reported in the past three months, signaling some investor confidence alongside broader performance considerations such as potential margin pressure and execution risks. Market commentary notes EnerSys’ strategic shift aims to meet FEOC standards and strengthen the U.S. supply chain, while acknowledging valuation and near‑term headwinds as factors to watch.
