The company reported record fourth-quarter 2025 revenue and full-year 2025 revenue of $114.2 million, with 2026 revenue guidance projected between $300 million and $400 million. Eos is expanding its manufacturing capacity with a new facility in Marshall, Pennsylvania, aiming for an annualized energy storage capacity of 8 GWh, and secured a $305.3 million loan guarantee from the U.S. Department of Energy in November 2024.
