Eos Energy manufactures zinc-based long-duration battery energy storage systems used to store renewable power and support grid reliability.

Eos repeatedly touted manufacturing progress driven by a transition to a highly automated battery manufacturing line and issued revenue guidance of $150 million to $160 million for fiscal year 2025.

The filed complaint alleges that Company statements were materially false and misleading because Eos was experiencing significant production inefficiencies, excessive battery line downtime, and delays in achieving quality targets, which undermined its ability to meet its stated guidance.

On February 26, 2026, before the market opened, 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 due 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 also issued weaker‑than‑expected 2026 revenue guidance due to slower‑than‑anticipated production progress and heightened execution risk.

Following these disclosures, Eos Energy’s stock price fell $4.39 per share, or approximately 39.4%, to close at $6.74.

Investors who suffered losses have until May 5, 2026, to seek appointment as lead plaintiff.
