Analyst reactions after earnings and guidance
Market reactions to First Solar's recent earnings and 2026 outlook have prompted multiple broker revisions. The company reported fourth-quarter earnings that missed expectations by 6% and issued 2026 revenue guidance of $4.9 billion to $5.2 billion. That guidance is cited as 17% below Street expectations and represents a 3% year-over-year decline.
Deutsche Bank downgraded First Solar from Buy to Hold and trimmed its price target to $245 from $300. Jefferies lowered its price target to $205 from $260 while keeping a Hold rating, citing weak guidance and limited visibility on recovery. HSBC moved the stock to Hold from Buy with a $211 price target, noting that net income matched the bank's estimates but fell slightly short of consensus. Barclays reduced its price target to $228 from $279 while maintaining an Overweight rating. RBC Capital cut its price target to $236 from $258 and kept an Outperform rating, attributing its adjustment to tariff policy pressures affecting the company’s outlook.
These broker updates underscore the market and analyst reassessment following weaker-than-expected guidance and various external pressures highlighted by the firms issuing revisions.
