First Solar shareholders have been invited to take charge of a securities fraud lawsuit. The Rosen Law Firm announced the class action on behalf of people who bought First Solar securities between February 26, 2025 and February 24, 2026, a span it calls the Class Period.
The cutoff for volunteers is August 24, 2026. Anyone who wants to be lead plaintiff must move the court by then. That person acts for the rest of the class in directing the case.
The allegations
First Solar trades on the Nasdaq under FSLR. According to the lawsuit, defendants overstated the company’s ability to manage the impact of U.S. tariff policy on its business. The suit also says they understated how far the company’s response, including intentional underuse of production facilities in Malaysia and Vietnam and an attempted relocation of production to the U.S., would drag on projected performance in fiscal 2026.
The lawsuit calls the defendants’ public statements materially false and misleading at all relevant times. It claims investors were harmed when the true picture came out.
What investors can do
Rosen said buyers during the Class Period may be entitled to compensation, with no out-of-pocket fees or costs, through a contingency fee arrangement.
Holding shares in that window does not oblige anyone to lead. No class has been certified, and until one is, investors are not represented by counsel unless they retain someone. They may pick their own lawyer or stay on as absent class members. Rosen said that sharing in a future recovery is not dependent on serving as lead plaintiff.
