EnerSys said it will close its legacy lead-acid battery manufacturing facility in Tijuana, Mexico, and transition the majority of production to its existing proprietary advanced Thin Plate Pure Lead (TPPL) plant in Springfield, Missouri.
The company said its proprietary TPPL technology delivers greater power density and improved discharge performance compared to legacy valve‑regulated lead‑acid batteries. TPPL solutions are suited for modern data center applications that require reliable, high‑output power over shorter discharge intervals, supporting increasingly demanding uptime and performance requirements.
EnerSys expects to incur a pre-tax charge of approximately $37 million under this plan when completed, the majority of which is expected to be incurred by the second half of fiscal year 2027, of which $14 million is expected to be a non-cash charge primarily from equipment write-offs. Cash charges of $23 million include severance, decommissioning and cleanup related to the facility. The restructuring is expected to deliver an annual estimated pre-tax benefit of approximately $20 million, beginning in fiscal year 2028, while ensuring continued product availability and customer support.
“The closure of our Tijuana facility and the transition of production to Springfield, Missouri will enable us to optimize our cost structure, maximize near-term advanced manufacturing production tax benefits, and mitigate future risks associated with potential tariffs while reinforcing our commitment to strengthening domestic industrial capacity and supply chain resilience,” said Shawn O’Connell, President and Chief Executive Officer at EnerSys. “These actions build on the investments we have made to scale our TPPL platform and enable us to better serve data center customers with solutions that deliver higher power density and strong performance for today’s increasingly demanding applications.”
