Eos Energy sued for fraud after manufacturing issues cause 39% stock drop

Eos Energy Enterprises faces a securities fraud class action lawsuit after its stock fell 39% on 26 February 2026. The lawsuit, filed in the US District Court for the District of New Jersey, alleges the company misrepresented near-term revenue growth and manufacturing capabilities. Eos Energy, which manufactures zinc-based battery energy storage systems, had guided fiscal year 2025 revenue of $150 million to $160 million whilst touting manufacturing progress.

The complaint alleges violations of the Securities Exchange Act. Investors have until 5 May 2026 to apply to lead the case. Law firm Bleichmar Fonti & Auld is representing plaintiffs on a contingency basis.
