First Solar stock tumbles on weak 2026 outlook — tariffs and permits now in the crosshairs
First Solar shares fell 13.6% to $210.12 Wednesday after issuing a weaker-than-expected 2026 sales forecast and warning of $125–$135 million in tariff costs. The company cited federal permitting delays and trade friction affecting demand and factory use. First Solar also filed a patent complaint with the U.S. International Trade Commission against several rivals. After-hours, the stock slipped another 0.17%.
