Eos Energy Enterprises, Inc.

Shares of Eos Energy fell over 35% on February 26, 2026, after the company reported Q4 and FY25 results that missed expectations. This included Q4 revenue of $58.0 million, well below analyst estimates of approximately $93 million. Eos also reported a Q4 gross loss of $54.4 million and a full-year adjusted EBITDA loss of $219.1 million, and disclosed FY25 revenue of $114.2 million. The company further stated that it reached its targeted 2 GWh annualized production capacity five weeks later than initially planned and that the CEO was “disappointed in not meeting revenue expectations.”

The complaint alleges that Eos Energy failed to disclose to investors that: (1) the Company was unable to achieve the ramp in production and capacity utilization required to achieve its previously set guidance; (2) the Company’s battery line downtime was running well above industry norms, the design intent of the line, and internal forecasts; (3) the Company was experiencing delays in the ability for its automated bipolar production to hit quality targets; (4) the Company’s inadequate systems and processes prevented it from ensuring reasonably accurate guidance and that its public disclosures were timely, accurate, and complete; and (5) as a result, Defendants’ positive statements about the Company’s business, operations, and prospects were materially misleading and/or lacked a reasonable basis at all relevant times.
