The Law Offices of Frank R. Cruz announces an investigation of Eos Energy Enterprises (“Eos Energy” or the “Company”) (NASDAQ: EOSE) on behalf of investors concerning the Company’s possible violations of federal securities laws.

What Is The Investigation About?

On February 26, 2026, Eos Energy announced fourth quarter and full year 2025 results, reporting, among other things, full year 2025 revenue of $114.2 million, falling far short of the Company’s previously issued guidance of $150 to $160 million. Management attributed these results to, in part, that “battery line downtime ran well above industry norms” and “the ability for the automated bipolar production to hit quality targets took longer than expected.” The Company further disclosed it had “uncovered inefficiencies that result in longer end-to-end production times.”

On this news, Eos Energy’s stock price fell $4.39, or 39.4%, to close at $6.74 per share on February 26, 2026, thereby injuring investors.
