Eos Energy Enterprises, Inc. PITTSBURGH, July 15, 2026 (GLOBE NEWSWIRE) -- Eos Energy Enterprises, Inc. (NASDAQ: EOSE) (“Eos” or the “Company”), America’s leading innovator in designing, manufacturing, and providing zinc-based long-duration energy storage (LDES) systems sourced and manufactured in the United States, today announced a strategic partnership with the Department of War to enhance the resilience of national defense infrastructure. Eos was awarded a Golden Dome for America contract to integrate mission-ready long-duration energy storage supporting requirements of the nation’s defense shield. The award was highlighted by President Donald Trump during Senator Dave McCormick's Defense and National Security Summit in Carlisle, Pennsylvania on July 15, 2026. “Eos in Pittsburgh just agreed to a multi-million-dollar partnership with the Department of War to build energy storage technology in support of our Golden Dome missile defense. Yeah we're building a golden dome over our country and its going to be a very effective one,” said President Donald J. Trump. Under the initiative, Eos’ Z3™ zinc-based long-duration energy storage technology will first be deployed as an initial prototype at a critical installation. The Z3 system is designed to secure power infrastructure and strengthen mission readiness through resilient, long-duration power. The initial deployment will demonstrate the value of American-made long-duration energy storage for national security applications. The program is structured to scale as national defense needs evolve. “This award validates the strategy we’ve built around American technology innovation, manufacturing and supply chains,” said Joe Mastrangelo, Eos Chief Executive Officer. “Today, we’re proving that America can still manufacture advanced technology at scale and deliver for our nation’s most critical missions.” Manufactured and assembled in Pittsburgh, Pennsylvania, Eos’ proprietary technology combines a non-flammable aqueous zinc chemistry with approximately 91% domestic content and a predominantly U.S.-based supply chain. The system is Section 842 NDAA- and FEOC-compliant, built around reliable performance, trusted manufacturing and secure sourcing. “We spent the last year building the relationships, compliance foundation and technical proof points the Department of War requires,” said Michelle Buczkowski, Eos Chief Administration Officer. “This award reflects that work. Eos is ready to deliver for the Department's mission at scale.” As the United States strengthens the resilience of its defense and critical infrastructure, reliable power has become a strategic capability. Long-duration energy storage enables facilities to maintain operational readiness, enhances energy security and provides the flexibility needed to support missions where uninterrupted power is essential. The selection of a commercially available American technology for this initiative reflects the growing role advanced energy storage can play in supporting national preparedness. "The Golden Dome should be built on American technology. Eos' technology will help secure the power infrastructure our military depends on, while creating good jobs right here in Pennsylvania," said Senator Dave McCormick. Eos is rapidly expanding domestic manufacturing capacity through its state-of-the-art Thorn Hill facility in the Pittsburgh region. With Eos’ second battery line now in commercial production, Thorn Hill serves as the cornerstone of the Company’s next phase of growth, adding automated manufacturing capacity for the Z3 platform and creating a scalable, repeatable foundation as Eos works toward 8 gigawatt-hours of annual production capacity in Allegheny County. The facility further strengthens Eos’ domestic supply chain, advances American energy independence and supports the Company’s commitment to create 1,000 high-quality jobs across the region.
