EnerSys to Acquire Ultralife Corporation in a $320 Million All-Cash Transaction

NEWARK, N.Y., Oct. 27, 2026 (GLOBE NEWSWIRE) -- Ultralife Corporation (NASDAQ: ULBI) today announced that it has entered into an Agreement and Plan of Merger (“merger agreement”) with EnerSys (NYSE: ENS) under which upon closing EnerSys will acquire Ultralife Corporation in an all-cash transaction valued at approximately $320 million, including the assumption of net debt.

Under the terms of the merger agreement, which has been unanimously approved by the Boards of Directors of both companies, Ultralife Corporation shareholders will receive $16.00 in cash for each share of Ultralife Corporation common stock they own. The purchase price represents a premium of 166% to Ultralife Corporation’s closing stock price on October 26, 2026.

Strategic Benefits of the Transaction:

Ultralife is highly complementary to EnerSys and a combination creates a compelling platform for continued innovation, customer support and growth. Together, we believe EnerSys and Ultralife would be well positioned to:

• Establish a unique portfolio of integrated, mission-critical power solutions by combining complementary products, engineering capabilities and application-specific design expertise;
  
• Increase scale and broaden exposure to the large and rapidly growing defense market with capabilities across mission-critical applications in munitions, soldier power, drones, counter drones, and autonomous systems accelerating focused growth;
  
• Expand EnerSys’ advanced defense power technology portfolio with the addition of Ultralife’s differentiated multi-chemistry capabilities, purpose-built advanced manufacturing capacity with existing security and environmental permits, and operational expertise to scale production of EnerSys’ proprietary liquid reserve battery technology; and
  
• Deepen customer relationships by creating a broader, Foreign Entity of Concern (FEOC)-compliant product portfolio for U.S. Department of War and allied country customers.
  
  

Management Commentary:

"Combining with EnerSys is an exciting next step that will allow us to unlock value and growth opportunities for both companies, while delivering substantial and certain cash value to Ultralife shareholders,” said Michael E. Manna, President and Chief Executive Officer of Ultralife Corporation. “This transaction is a testament to the hard work and dedication of our entire organization, and now offers even greater opportunities for our valued employees. We look forward to partnering with the EnerSys team with the combined scale, resources, and shared vision to accelerate innovation and better serve our global customer base."

“This acquisition is a compelling strategic fit for EnerSys and directly advances our strategy to build a broader, more differentiated defense power platform,” said Shawn O'Connell, President and Chief Executive Officer of EnerSys. “Building on the success of our recent acquisitions, Ultralife expands our portfolio of advanced, reliable, high-performance power solutions. Together, we will be better positioned to support the U.S. Department of War (DoW) and allied forces with leading-edge, cost-effective technologies for the increasingly electrified battlefield of the future. We know the Ultralife business and its team well, and are confident that our shared commitment to engineering, problem solving, and customer focus will create a strong cultural fit.
