First Solar (FSLR) Stock Looks Cheap On Cash Flow But Earnings Lag
First Solar stock enters late August 2026 with a strong five year share return and a current price that still screens as cheap on several valuation checks. The Discounted Cash Flow (DCF) intrinsic value estimate and earnings multiples both suggest the stock trades at a discount even after recent policy news around tariffs.
- Over the past 5 years, First Solar has delivered a share price gain of 117.4%, which puts recent price weakness into the context of a longer period of solid compounding.
- The recent 15% tariff on polysilicon imports can support domestic pricing and cash flow expectations for First Solar, although any change in trade policy or industry pricing pressure remains a key risk to those cash flows.
- The broader valuation checks lean cheap, with the stock scoring a high value rating of 5 out of 6 and both the Discounted Cash Flow (DCF) intrinsic value estimate and earnings multiples pointing to undervaluation.
The issue now is whether First Solar's current share price already reflects the improved policy backdrop and long term cash flow outlook, or if there is still a meaningful discount to intrinsic value.

Does First Solar Look Undervalued on Cash Flow?
The Discounted Cash Flow (DCF) model values First Solar by projecting future free cash flows and discounting them back to today. For First Solar, the latest twelve month free cash flow sits at about $836 million, and the model assumes growing cash flows over time using a 2 Stage Free Cash Flow to Equity approach. On those inputs, the DCF points to an estimated intrinsic value of about $340 per share.
That intrinsic value is roughly 39.8% above the current share price, which implies the stock screens as undervalued on cash flow alone. The recent 15% tariff on polysilicon imports supports the case for stronger domestic cash generation, and that helps explain why a cash flow based model can sit well above where the market currently prices First Solar. According to this Discounted Cash Flow model, the stock appears undervalued relative to its estimated intrinsic value.
Our Discounted Cash Flow (DCF) analysis suggests First Solar is undervalued by 39.8%. Track this in your watchlist or portfolio, or discover 45 more high quality undervalued stocks.
Is First Solar Still Cheap on Earnings?
The P/E ratio is a useful cross check for First Solar because earnings are a clear anchor for how the market is pricing its current profitability. Right now, First Solar trades on a P/E of about 12.6x, which is well below the semiconductor industry average of 47.4x and also below the peer group average of 59.6x.
A tailored fair P/E ratio for First Solar, which takes into account its margins, growth profile, market size and risk, comes out at about 30.1x. That is more than double the current P/E. This wide gap suggests the stock is priced as if its earnings deserve a significant discount to typical sector and peer valuations, even though the broader valuation framework points to a higher level as reasonable.
On this P/E multiple cross check, First Solar stock appears undervalued compared with both its sector and what the fair ratio model implies.

The Bottom Line
For First Solar, both the Discounted Cash Flow (DCF) intrinsic value estimate and the earnings multiple view point to an undervalued stock, and the broader checks support that message rather than contradict it. The key question now is whether the market eventually moves closer to that intrinsic value, or whether policy and tariff uncertainty keep a lid on the valuation. The crux of the bull versus bear debate is how resilient First Solar's cash flows remain if trade rules or pricing pressure shift from here.
