The law firm of Kirby McInerney LLP announces that a class action lawsuit has been filed on behalf of investors who acquired Eos Energy Enterprises, Inc. (“Eos” or the “Company”) (NASDAQ:EOSE) period of November 5, 2025 through February 26, 2026, inclusive (“the Class Period”).
The lawsuit alleges 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; and (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.
On February 26, 2026, Eos reported a substantial net loss of approximately $970 million for fiscal year 2025 and disclosed full-year 2025 revenue that fell short of the guidance the company had repeatedly reaffirmed, including as recently as November 2025. At the same time, Eos issued weaker-than-expected 2026 revenue guidance. Eos attributed its 2025 results to heavy spending to scale its manufacturing operations, including ramp-up inefficiencies, automation-related costs, and large non-cash financing and asset write-down charges. Eos attributed the disappointing 2026 revenue forecast to slower-than-anticipated production progress and heightened execution risk. On this news, the price of Eos shares declined by $4.39 per share, or approximately 39.4%, from $11.13 per share on February 25, 2026 to close at $6.74 on February 26, 2026.
