First Solar Shares Retrace Despite Strong Revenue Growth

First Solar Inc. shares closed at USD 195.96 on Nasdaq on September 18, 2026, marking a significant decline from the 52-week high of USD 320.95. As reported by GN auto stocks/energy-stocks: solar stocks, the stock is currently trading roughly 39 percent below that peak. This price action reflects broader sector weakness rather than company-specific operational failures, with the thin-film manufacturer experiencing pressure alongside other renewable energy peers.

The recent sell-off was driven by renewed concerns over interest rates and project financing costs. On September 19, the stock fell approximately 4 percent to USD 193.38, moving below key short and long-term moving averages. Technical indicators show immediate resistance near USD 202.41, indicating that the stock faces sustained selling pressure in the near term despite its underlying financial strength.

Valuation Gap Persists Amid Sector Weakness

Despite the technical decline, First Solar Inc. trades at a discount to various fair value estimates. The current share price is approximately 25 percent below an internally estimated fair value of USD 263. Investing.com notes that the company has a market capitalization of USD 20.77 billion and a trailing price-to-earnings ratio of 11.9 times. This multiple is consistent with mature industrial firms rather than high-growth renewable energy players.

Analyst consensus suggests potential upside if market sentiment normalizes. Estimates indicate a fair value upside of 23.7 percent and an analyst target upside of 35.7 percent. These figures imply that the market is currently pricing in significant risk regarding financing conditions, which may not fully reflect the company's current earnings power or long-term demand for its technology.

Revenue Growth Supports Long-Term Fundamentals

First Solar Inc. has demonstrated robust top-line expansion, with revenue compounding from USD 2.92 billion in fiscal 2021 to USD 5.22 billion in fiscal 2025. This near-doubling of sales highlights strong demand for its thin-film solar modules. Trailing twelve-month earnings per stand at approximately USD 16, supporting the current low single-digit forward price-to-earnings multiple range of 11 to 12 times.

Cash flow generation has become a central part of the investment thesis. The latest twelve-month free cash flow stands at USD 836.2 million, with projections suggesting this stream could grow into the low single-digit billions over the next decade. This cash generation provides a buffer against the current volatility in renewable energy financing costs and supports the company's balance sheet stability.

Market Sentiment Drives Short-Term Price Action

The disconnect between fundamental performance and share price is largely attributed to macroeconomic factors. Investors remain cautious regarding the cost of capital for renewable infrastructure projects, which has weighed on the entire solar sector. First Solar Inc. is thus caught in a broader market adjustment, where sector-wide headwinds are temporarily overshadowing its individual revenue growth and earnings consistency.
