First Solar investors who bought securities between February 26, 2025 and February 24, 2026 have until August 24, 2026 to seek appointment as lead plaintiff in a securities class action, with Rosen Law Firm issuing a fresh reminder that a complaint has already been filed. The suit alleges the company and certain executives overstated First Solar's ability to manage U.S. tariff policy and understated how measures such as underutilizing plants in Malaysia and Vietnam and trying to shift production to the U.S. could hurt fiscal 2026 results. Earlier notices tied the claims to a January 7, 2026 Jefferies downgrade that cited lowered guidance, de-bookings, margin compression and international facility underutilization, and to a February 24, 2026 earnings release that missed expectations and gave lower-than-expected FY 2026 revenue guidance, after which Baird downgraded the stock; First Solar shares fell 10.29% to $241.11 on January 7 and 13.61% to $210.12 on February 25. Rosen also said no class has been certified, meaning investors may seek lead-plaintiff status, retain their own counsel or remain absent class members without affecting any potential recovery.
