First Solar (FSLR) is back in focus after renewed optimism around potential U.S. Section 232 polysilicon tariffs, with investors weighing possible benefits for domestic solar manufacturers against ongoing legal headlines and recent share price volatility.

Recent headlines have left First Solar trading at US$233.06, with a 1 year total shareholder return of 31.63% and a 5 year total shareholder return of 147.17%. Over shorter periods, the 30 day share price return has fallen 16.47%, while the 90 day share price return is up 21.19%. This suggests momentum has cooled in the short term but remains positive over a longer window.

After a sharp run up on tariff hopes and index additions, First Solar now trades only slightly below consensus targets and at a wider discount to some intrinsic value estimates. This raises the question of where a reasonable fair value range actually sits.

Most Popular Narrative: 4.3% Undervalued

On the most followed narrative, First Solar's fair value of $243.59 sits slightly above the last close at $233.06, which frames the current tariff driven debate around only a modest valuation gap.

Recent U.S. policy changes, specifically strengthened incentives and tighter restrictions against foreign entities of concern (such as China) under the new reconciliation legislation, are supporting First Solar's competitive position, supporting demand for domestically produced modules, and enabling the company to capture higher long-term contracted pricing, directly affecting forward revenue visibility and gross margins.

The narrative focuses on measured revenue growth, changes in margins and a future earnings multiple that reframes what today’s price may imply.

Result: Fair Value of $243.59 (UNDERVALUED)

However, this fair value narrative for First Solar still relies heavily on supportive U.S. policy and assumes that trade disputes and tariff outcomes do not undermine margins or demand.
