Protect Your Yield

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, announced the start of commercial production at its Thorn Hill manufacturing facility in Marshall Township, Pennsylvania, following the successful completion of Site Acceptance Testing (SAT) for Battery Line 2.

The launch of Battery Line 2 represents a major milestone in Eos’ evolution from proving its manufacturing model to scaling it. Following the successful deployment of Line 1, the Company has now demonstrated its ability to replicate, improve, and implement automated battery production at a second facility, helping reduce execution risk associated with future manufacturing expansion.

Eos is expanding production capacity to support growing customer demand, execute against its contracted backlog, and position the Company for the next phase of growth. Simultaneously, Line 1 surpassed its full-year 2025 production in just the first 164 days of 2026. This achievement, together with the startup of the new line, establishes a proven blueprint for future capacity additions while advancing Eos toward its goal of reaching 4 GWh of annual manufacturing capacity by the end of 2026.

Demand for Eos technology continues to build across multiple applications, supported in part by Frontier Power USA’s (FPUSA) 2 GWh capacity reservation agreement. In May 2026, FPUSA signed its first transaction to acquire a 480 MWh battery project portfolio in Texas from Bimergen Energy which was followed by FPUSA’s strategic framework agreement with Stella Energy Solutions to further advance a 2 GWh pipeline built around Eos technology.

In the United Kingdom, Frontier Power Energy Holding Ltd (Frontier Power UK) acquired the rights to the Ayr and Busby projects in Scotland, which are expected to utilize approximately 2.8 GWh of Eos Z3 Indensity™ systems under an existing framework agreement that Frontier Power UK and Eos announced in April 2025. While subject to customary development milestones, project-specific agreements and closing conditions, these opportunities demonstrate the growing demand that Line 2 was built to support.

“Battery Line 2 demonstrates our ability to continuously improve as we scale,” said John Mahaz, Chief Operating Officer of Eos. “We took the lessons learned from commissioning and operating Line 1 and incorporated them directly into the design of this facility and production line. The result is a more efficient manufacturing environment with better flow and a stronger foundation for future expansion. Most importantly, it validates that our manufacturing system can be replicated and scaled with discipline.”

Battery Line 2 was designed using the operational experience and manufacturing insights gained from commissioning Line 1. The line incorporates single-piece flow architecture, enhanced process redundancy, and advanced pick-and-place gantry systems designed to improve throughput and support more efficient production at scale.

The Thorn Hill facility itself was engineered to optimize manufacturing flow and productivity. Compared to Battery Line 1, the new layout reduces raw material travel by 86% and shortens overall production line length by 40%, improving material handling, reducing complexity, and supporting higher operating efficiency.

Production operators are onsite at the Thorn Hill facility, and Line 2 has begun producing commercial batteries. The line will ramp throughout the year, with subassemblies coming online in the early third quarter and full production targeted in the fourth quarter of 2026.
