First Solar Shares Plunge 14% on Disappointing Sales Forecast

Key Facts

1First Solar shares tumbled nearly 14% in after-hours trading.
2The company forecasted current-year sales below analyst estimates.
3The company expects higher product prices following additional tariffs on foreign-made solar panels.

Shares of First Solar, the largest U.S. solar panel manufacturer, tumbled nearly 14% in after-hours trading following a weak financial outlook. The company issued a full-year sales forecast that significantly missed analyst estimates, sparking concerns over its near-term growth trajectory. While First Solar anticipates higher product pricing due to new tariffs on foreign-made solar panels, this potential upside failed to reassure investors. The downbeat forecast overshadowed the benefits of increased pricing power, highlighting the sensitivity of the renewables sector to sales volume targets. This significant drop in a sector leader is expected to weigh heavily on broader clean energy benchmarks. Market participants are now closely monitoring how these sales projections will impact industry-wide ETFs such as TAN and ICLN.
