Investors File Class Action Lawsuit Against First Solar Over Tariff Impact

The litigation, docketed as 26-cv-03787, represents investors who purchased First Solar securities between February 26, 2025, and February 24, 2026. The complaint claims that while the company publicly maintained that its market position remained robust despite shifting trade regulations, it simultaneously failed to disclose that its strategic responses—specifically the underutilization of production plants in Malaysia and Vietnam—would severely impair its 2026 fiscal performance.

Market skepticism began to crystallize on January 7, 2026, when Jefferies downgraded the stock from Buy to Hold, citing significant de-bookings and margin compression. Following the analyst report, First Solar shares dropped 10.29%. The downward pressure intensified on February 24, 2026, when the company reported quarterly earnings that missed expectations and issued conservative revenue guidance for the coming year. Baird Research subsequently downgraded the stock to Neutral, and the share price slid an additional 13.61% the following day. Investors seeking to serve as lead plaintiff in the case have until August 24, 2026, to petition the court.
