Why Is Eos being Investigated for Securities Fraud?
Eos is being investigated for violations of the federal securities laws following a significant stock drop. The decline in Eos’s stock price caused significant losses to investors.
Eos manufactures zinc-based long-duration battery energy storage systems used to store renewable power and support grid reliability.
BFA is investigating whether Eos misrepresented its near-term revenue growth, as well as the timing, scale, execution, and reliability of its manufacturing efforts.
Why did Eos’s Stock Drop?
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 stock dropped over 39% on February 26, 2026.
