Eos Energy Investors Face May 5 Deadline to Seek Lead Role in Securities Case

Overview

• The federal class action, Yung v. Eos Energy Enterprises, Inc. (2:26-cv-02372), is pending in New Jersey and investors have until May 5, 2026 to ask the court to be lead plaintiff.
• Plaintiffs say Eos misled investors about its ability to scale production, with battery-line downtime far above norms, delays in its automated bipolar line hitting quality targets, and systems that could not support reliable guidance.
• Investors learned the extent of the problems on February 26, 2026 when Eos reported 2025 revenue of $114.2 million against guidance of $150–$160 million and an adjusted EBITDA loss of $219 million.
• Eos said heavy manufacturing downtime and slower-than-expected quality ramp on its automated line drove the shortfall, and the stock fell about 39% to close at $6.74 that day.
• Multiple firms, including Rosen Law, Hagens Berman, Berger Montague, and Bleichmar Fonti & Auld, are recruiting class members and seeking whistleblowers as the case remains in early stages with no class certified.
