READING, Pa., August 12, 2026 (BUSINESS WIRE) -- EnerSys (NYSE: ENS), a global leader in stored energy solutions for industrial, infrastructure, and defense applications, announced today results for its first quarter fiscal 2027, which ended on July 5, 2026.

“In the first quarter of fiscal year 2027, we delivered top line growth aligned with our long-term value creation framework,” said Shawn O'Connell, President and Chief Executive Officer of EnerSys. “Adjusted diluted EPS excluding IRC 45X increased 92% year-over-year, or 42% year-over-year excluding a one-time benefit from tariff refunds, demonstrating the effective combination of our diversified business and EnerGize strategic framework.

“Momentum across data centers, communications, and aerospace & defense is generating strong sales growth and margin expansion, offsetting the delayed recovery of material handling demand, and enabling another record first quarter result. We continue to advance on the commercialization of our next-generation products, progress on our planned lithium cell facility, and expand our services capabilities to accelerate our growth.

“As we communicated in our Investor Day in June, our strategic priorities are well defined. We are focused on our core markets where we have a right to win, we are applying our differentiated energy storage solutions to address the critical customer challenges of energy security and labor scarcity, and we are executing as a well-aligned organization to drive profitable growth and long-term shareholder value,” O’Connell concluded.
