First Solar Inc. stock rose 2.9% in after-hours trading following the release of second-quarter 2026 results, as the company posted an adjusted earnings per share figure that substantially exceeded expectations.
Adjusted EPS came in at $3.92, comfortably above the analyst consensus of $3.01 - a roughly 30% outperformance versus estimates. Quarterly revenue was $1.06 billion, which matched the consensus forecast exactly.
Investors also reacted to a pronounced improvement in profitability. First Solar reported a gross margin of about 57%, an expansion of roughly 12 percentage points compared with the same quarter a year earlier. Management attributed this stronger margin profile to several specific factors: an estimated $89 million net benefit tied to IEEPA tariff-related provisions, improved qualification for Section 45X advanced manufacturing tax credits, and lower logistics costs. The company noted that these elements together emphasize its structural position as the only major U.S.-headquartered solar manufacturer.
On demand visibility, First Solar said it had a $13.6 billion order backlog at quarter end. The company reiterated its full-year 2026 guidance, while its revenue outlook of $5.05 billion was slightly below the $5.08 billion analyst consensus.
The broader market offered a stable backdrop during the regular trading session, with the S&P 500 up 0.2%, the Dow Jones Industrial Average rising 0.1% and the Nasdaq gaining 0.6%. Solar-sector peers were also trading positively on the day, indicating a generally supportive risk environment. Nevertheless, the timing and size of First Solar's after-hours move appeared to be driven primarily by its own quarterly results rather than by sector momentum alone.
Taken together, the company's decisive earnings beat, notable margin expansion to multi-year highs, confirmation of guidance and a sizeable backlog gave investors concrete reasons to bid the stock higher after the market close, extending gains that had begun during the regular session.
