Summary
• First Solar (FSLR) surges 12.65% intraday, hitting a 52-week high of $268.29
• Q3 2025 earnings report reveals $1.6B revenue (beating estimates) and $4.24 EPS

• Louisiana 3.5 GW manufacturing facility and 53.7 GW contracted backlog drive optimism

First Solar’s meteoric rise on October 31, 2025, reflects a confluence of robust earnings, strategic expansion, and analyst enthusiasm. The stock’s 12.65% surge—its largest intraday gain in over a year—signals a pivotal moment for the solar leader. With a record 5.3 GW in Q3 module shipments and a $16.4B backlog, FSLR’s momentum is underpinned by tangible operational progress and policy-driven demand.

Earnings Outperformance and Analyst Optimism Ignite FSLR’s Rally
First Solar’s explosive move stems from its Q3 2025 earnings report, which revealed $1.6B in revenue (exceeding the $1.56B consensus) and $4.24 EPS. The company narrowed FY25 guidance to $14–$15 EPS and $4.95B–$5.20B in sales, citing strong demand and a 53.7 GW contracted backlog. Analysts amplified the bullish sentiment: Keybanc raised FSLR’s price target from $100 to $150, while BMO and Morgan Stanley reiterated overweight/outperform ratings. Additionally, the Louisiana 3.5 GW manufacturing facility and strategic partnerships with Longroad Energy (2 GW expansion) underscore FSLR’s positioning in the U.S. solar boom.

Solar Sector Gains Momentum as Canadian Solar (CSIQ) Surges 11.87%
The broader solar sector is rallying alongside FSLR, with Canadian Solar (CSIQ) surging 11.87% on October 31. Both stocks benefit from U.S. policy tailwinds and global demand for clean energy. FSLR’s 12.65% gain outpaces CSIQ’s rally, reflecting its unique focus on thin-film technology and domestic manufacturing. However, CSIQ’s lower valuation (P/S of 3.2 vs. FSLR’s 5.79) suggests potential for further outperformance if FSLR’s premium pricing holds.
