EnerSys Announces Strategic Manufacturing Restructuring: Tijuana, Mexico Facility Closure and Optimization of U.S. Manufacturing Footprint

Key Terms

thin plate pure lead (tppl) technical

Thin plate pure lead (TPPL) is a battery plate technology that uses very thin sheets of nearly pure lead to form the positive and negative plates inside lead‑acid batteries, allowing faster charging, higher power delivery, and longer cycle life compared with conventional thicker, alloyed plates. For investors, TPPL signals potentially better performance and durability in batteries used for backup power, renewable storage, and electric vehicles—similar to swapping a heavy, slow engine for a lighter, quicker one—affecting product competitiveness and demand.

valve‑regulated lead‑acid batteries technical

Sealed lead‑acid batteries that are built to recombine internal gases and only release pressure through a safety valve, so they don’t need regular water refills or routine maintenance. Think of them as a sealed household battery that provides reliable backup power for things like telecom, data centers, and emergency systems; investors care because their lifespan, safety, replacement cycle and regulatory handling affect operating costs, capital needs and product demand across multiple industries.

READING, Pa.--(BUSINESS WIRE)-- EnerSys (NYSE: ENS), a global leader in stored energy solutions for industrial applications, today announced a strategic manufacturing realignment to enhance operational efficiency. As part of this initiative, EnerSys 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, leveraging its investments to expand capacity within its U.S. manufacturing network.

EnerSys’ proprietary TPPL technology delivers greater power density and superior discharge performance compared to legacy valve‑regulated lead‑acid batteries. TPPL solutions are well 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.”

EnerSys remains committed to maintaining service continuity for its customers throughout this transition. The Company will work closely with employees, customers, and other stakeholders to ensure a seamless shift in production and supply chain logistics.
