First Solar Faces Class Action Lawsuit Over Tariff Impact Disclosures

The legal action, filed in the U.S. District Court for the Eastern District of New York, covers investors who acquired First Solar securities between February 26, 2025, and February 24, 2026. Plaintiffs contend that company leadership overstated their capacity to mitigate the impact of import tariffs on Malaysia and Vietnam-based production, while failing to disclose the extent to which relocating operations would damage projected 2026 performance.

Financial strain became public on January 7, 2026, when an analyst downgrade from Jefferies highlighted significant margin compression and facility underutilization, triggering a 10.29% drop in share price. Further pressure mounted on February 24, 2026, when the company reported quarterly earnings that missed market expectations and issued weak revenue guidance. Following that disclosure, the stock price fell an additional 13.61%. Investors seeking to serve as lead plaintiff have until August 24, 2026, to file with the court.
