First Solar (FSLR) Draws Mixed Valuation Attention, Is It Still Below Fair Value?

Simply Wall St · 3d ago

Why First Solar Is Back in Focus

First Solar (FSLR) has moved back into the spotlight as investors weigh its large contracted module backlog against questions around new order pricing, cash conversion, and fresh patent lawsuits.

The recent 1-day share price gain of 1.53% to US$174.43 comes after a year-to-date share price decline of 36.42%, while the 1-year total shareholder return is down 21.91% and the 5-year total shareholder return is up 58.24%. Over the past quarter, a 15.29% fall in the 90-day share price return and a 12.72% decline over 30 days point to fading near term momentum as investors reassess how First Solar’s backlog, order pricing, and legal actions feed into longer term expectations.

Compare First Solar’s setup with a curated group of peers by scanning our 42 power grid technology and infrastructure stocks that are also tied to grid, tariff, and policy driven demand shifts.

First Solar now trades well below both analyst targets and intrinsic value estimates after a sharp pullback. Does that gap signal mispricing, or a fair mark on backlog quality, pricing risk, and legal overhangs?

Most Popular Narrative: 34% Undervalued

Against a last close of US$174.43, the most followed narrative pegs First Solar’s fair value at US$263, which implies a sizable valuation gap that centers on policy support, booked watts, and litigation risk rather than near term earnings noise.

First Solar is the only scaled U.S. thin-film module maker with a multi-year contracted book, domestic-content advantage, and Section 45X credits running through the early 2030s. Q2 2026 showed the earnings power of that setup, revenue was a little light year-on-year, margins and EPS were not.

See why 30 investors see First Solar as 34% undervalued.

Result: Fair Value of $263 (UNDERVALUED)

Still, the patent dispute around TOPCon technology and the Swift Current performance lawsuit could weigh on confidence if they escalate or prompt higher warranty reserves.
