$24 million state-led economic development package underscores the shared commitment between Eos and Pennsylvania to advance U.S. manufacturing and job creation

Expansion reinforces the Company’s progress and transformation as Pennsylvania becomes a national hub for energy, technology, and manufacturing innovation

PITTSBURGH, Oct. 21, 2025 (GLOBE NEWSWIRE) -- Eos Energy Enterprises, Inc. (NASDAQ: EOSE) ("Eos" or the “Company”), an American energy company and the leading innovator in designing, sourcing, manufacturing, and providing zinc-based battery energy storage systems (BESS) manufactured in the United States, today announced the next phase of its growth strategy with the expansion of its U.S. manufacturing footprint and the establishment of a new software hub strengthening American energy storage capacity, energy independence, and industrial job growth.

In partnership with Pennsylvania Governor Josh Shapiro and Allegheny County, the Company was awarded a joint $24 million economic development package to support U.S. manufacturing and the continued growth of 1,000 high quality American jobs. The incentive package will help the Company scale operations to meet growing market demand driven, in part, by AI infrastructure, while advancing energy innovation in Pennsylvania.

“Energy storage is the backbone of a modern energy system, and this significant milestone marks our progress to bring America’s battery to scale,” said Joe Mastrangelo, Eos Chief Executive Officer. “Through Project AMAZE, we’re proving that you can make things in America again by building world-class capacity, pairing advanced manufacturing with innovative software, and doing it here in Pennsylvania to ensure a more energy-efficient and secure future. We thank Governor Shapiro, Allegheny County, the Allegheny Conference on Community Development, and the Pittsburgh Technology Council for their unwavering support and shared vision for advancing Americas quest to lead in energy.”

Eos will expand its manufacturing capacity with a new state-of-the-art 432,000 sq. ft. facility in Marshall Township, PA, that will house additional production lines that complement the Company’s existing Turtle Creek manufacturing facility with plans to reach 8 GWh of annualized energy storage capacity. The new facility enables Eos to transition from single piece flow operations to high-efficiency, large-scale production, marking the culmination of years of process development designed to bring U.S. made energy storage to market at scale.

“The demand for energy is going up — and my Administration is capitalizing on Pennsylvania’s strengths as a national energy leader and net energy exporter to attract leading energy manufacturers like Eos Energy to the Commonwealth,” said Governor Shapiro. “We’re doubling down on our efforts to aggressively compete for — and win — major projects like this one by cutting red tape, building out our skilled workforce, and investing in the next generation of energy technology. I’m proud that Pennsylvania will be home to Eos’ new global headquarters — and my Administration will continue to work to cut energy costs, create good-paying jobs, and position the Commonwealth to continue to be a national energy leader for decades to come.”

Eos will also establish a new software hub at Nova Place, Pittsburgh’s premiere technology and innovation center, that supports the Company’s growing workforce and proprietary battery management system, software, controls and analytics platform, DawnOS TM . Eos joins a thriving community of other advanced manufacturing, data/telecommunications, AI, electric utilities, and robotics leaders in Pittsburgh’s innovation headquarters.

As part of its expanding software and engineering focus, the Company plans to deepen its partnership with Carnegie Mellon University, a leading institution in robotics, AI, computer science, and engineering to further develop a state-of-the-art workforce to work in Eos’ software hub.

“Carnegie Mellon University is thrilled to celebrate this milestone with Eos, and we are looking forward to the many opportunities it unlocks – for Pittsburghers, our students, and America’s bright future in manufacturing,” said CMU President Farnam Jahanian. “On behalf of the CMU community, I extend my sincere congratulations to Pennsylvania Governor Josh Shapiro and Eos CEO Joe Mastrangelo and their teams for leading the way in strengthening Western Pennsylvania’s roles as an innovation engine for the nation and as a driver of the talent that will power it.”

“Pennsylvania has an extensive history of being at the forefront of innovation. We’re proving that in Pittsburgh you can not only build products in America but also offer world class education and intellectual capabilities to grow emerging industries,” said Pranesh Rao, Eos Senior Vice President of Storage System Engineering. “Building our software hub in Pittsburgh—surrounded by talented workers and a fast-growing innovation ecosystem—is both a strategic move and a catalyst to propel Eos to the next level.”
