Revenue fell. Profit rose. That combination usually signals a business in trouble. At First Solar, it signals something different: a manufacturer extracting more value from every watt it ships, right as trade policy raises the floor under import pricing.
First Solar reported Q3 2026 earnings of $5.30 per share, beating the Zacks consensus of $4.64 by 14.2%, even as net sales fell 23% year over year to $1.23 billion. Operating margin hit 44.4%, up 15.1 percentage points from the same period last year. The company did less volume and made more money doing it. That is the cadmium-telluride business model in one line.
Full-year 2026 net sales guidance was cut to $4.60 to $4.90 billion from the prior $4.90 to $5.20 billion. Volume sold guidance was trimmed to 16.0 to 17.0 gigawatts, down from 17.0 to 18.2 gigawatts. Wall Street duly punished the stock. Shares were down about 5% in early pre-market trading on October 30, 2026 after the report. But the guidance cut has a specific source that most of the sell-off ignored.
In its Q3 materials, the company said contracting discipline and Section 232 uncertainty moderated booking volumes. First Solar is not necessarily losing orders to cheaper rivals. It is holding back signings because the Section 232 regime that takes effect December 4, 2026 is set to reset the pricing floor for imported polysilicon products, including certain solar inputs. The August 2026 presidential proclamation set minimum import prices that include $0.38 per watt for solar modules and also imposed an additional 15% ad valorem duty on specified polysilicon ingots and derivatives, effective December 4, 2026.
First Solar is the world’s largest thin film PV solar module manufacturer and the largest PV solar module manufacturer in the Western Hemisphere, and its cadmium-telluride panels do not rely on crystalline silicon supply chains. That means the same rules that pressure many import-dependent competitors can protect its pricing. BMO has said the new floor could push U.S. module prices toward $0.43 to $0.44 per watt. Any contract signed after that pricing shift lands at better economics for First Solar than anything booked today.
The separate risk is one the bulls tend to skip over. First Solar’s 2026 outlook assumes $2.07 to $2.19 billion of Section 45X tax credits. Gross profit guidance is $2.4 to $2.6 billion. At the midpoint, those credits represent roughly 85% of guided gross profit. Strip out the subsidy and the underlying margin picture looks narrower. That is the question the December 4 tariff and minimum import price date cannot answer on its own.
First Solar is completing its sixth U.S. manufacturing facility, located in South Carolina, to onshore final production processes for modules initiated by its international fleet. In its Q3 filing, the company said phase one of the South Carolina facility commenced commercial production in September 2026, and it expects phase two to commence operations in mid-2027. For Q4 2026, management guided to module sales of 4.3 to 5.3 gigawatts, including 3.4 to 4.3 gigawatts from U.S. manufacturing operations. The South Carolina facility shifts that domestic mix higher into 2027.
CEO Mark Widmar described Section 232 as a structural change in how the United States approaches solar manufacturing. He is the CEO of the company that benefits most from that change, so the framing deserves scrutiny. What it does correctly identify is that the competitive floor under First Solar’s pricing is now more regulatory than cyclical. Traders watching the stock near $200 are really watching whether the post-December contract pipeline confirms that pricing power, or whether slower bookings persist into a quarter where the policy cover finally arrives.
