Sustainability Report FY2025

A word from our CEO

As I begin my journey as CEO of EnerSys, I am honored to lead an organization with a critical mission and a proud legacy of powering the world’s most essential systems. This moment marks both a continuation of our success and an opportunity to elevate our ambitions. I am energized by the chance to embed sustainability and efficiency more deeply into our operations—cornerstones that will define both my leadership and our path forward.

EnerSys is more than a battery manufacturer, we are the largest supplier of batteries to the U.S. Department of Defense. Our energy storage technologies power mission-critical systems across air, land, sea, and space, from military aircraft and submarines to secure communications and unmanned systems. These applications form the backbone of U.S. defense infrastructure, and EnerSys is proud to help keep them running.

Within our operations, we’ve taken significant steps to establish Centers of Excellence across the business. These hubs of expertise are streamlining processes, driving standardization, and accelerating continuous improvement, ensuring we operate with precision, agility, and focus.

Looking ahead, my vision for EnerSys is clear: embed sustainability, resilience, and operational excellence into every part of our enterprise. These values are not just strategic, they are foundational to delivering long-term value to our customers, communities, and shareholders.

Thank you for reading our FY25 Sustainability Report and for your continued partnership with EnerSys.

Sincerely,

Shawn O’Connell
President & CEO

A word from the Chair of the EnerSys Nominating and Corporate Governance Board Committee

Over the past year, EnerSys has demonstrated remarkable adaptability and strategic foresight-attributes made possible by our long-standing commitment to governance and sustainability. From the acquisition of Bren-Tronics to a leadership transition, our strong governance framework has guided every decision, ensuring continuity and resilience in times of change.

Amid shifting external dynamics, including evolving regulatory and policy environments, our commitment to efficiency and long-term value remains constant. For us, sustainability is not a trend - it’s a proven business strategy. It enhances our operational performance, reduces risk, and drives cost savings. Most importantly, it positions EnerSys to lead with resilience and reliability, no matter the broader landscape.

The Board’s Nominating and Corporate Governance Committee remains actively engaged in shaping and overseeing these efforts. We are proud of the tangible progress our teams continue to deliver - progress that drives operational excellence and reinforces EnerSys’ role as a vital contributor to the domestic energy supply chain.

As we move forward, we do so with clarity of purpose and strategic discipline. I am confident that our shared commitment to sound governance and a pragmatic, results-driven sustainability strategy will continue to power EnerSys into the future.

Sincerely,

Rudolph Wynter
Chair of the EnerSys Nominating
& Corporate Governance Committee
