Recent earnings and guidance
First Solar’s fourth-quarter results and its forward guidance for 2026 have been central to recent market discussion. The company reported fourth-quarter earnings that missed expectations by 6%. Management’s revenue projection for 2026 also came in well below analysts’ forecasts, prompting several firms to revise their views.
Analyst actions and commentary
- Deutsche Bank downgraded First Solar from Buy to Hold, citing a weak outlook and noting that the company’s 2026 revenue guidance was roughly 17% below Street expectations.
- GLJ Research likewise moved its rating to Hold, pointing to the fact that First Solar’s 2026 guidance missed across all key metrics called out by the firm, including revenue and EBITDA.
Price-target adjustments
- Guggenheim reduced its price target from $312 to $269 while keeping a Buy rating.
- Barclays trimmed its target to $228 from $279 and retained an Overweight rating.
- Jefferies lowered its target to $205 from $260 and continues to rate the stock as Hold.
These revisions reflect concerns tied to the company’s weaker-than-expected guidance and the limited visibility around the timing and magnitude of any recovery, even as some firms express a cautiously optimistic long-term outlook.
