First Solar Q1 2026: Record Revenue and Margins Fueled by Domestic Manufacturing Boom (FSLR Q1 2026 Earnings Call)

Record Revenue and Margin Expansion

First Solar reported a blowout first quarter for 2026, generating a record $1.0 billion in net sales, representing a 24% year-over-year increase. The top-line growth was driven by a 31% increase in module volume sold. Profitability metrics were equally impressive, with first-quarter gross margin expanding roughly six percentage points year-over-year to 47%. This massive margin expansion was primarily fueled by a higher volume of modules qualifying for Section 45X tax benefits under the Inflation Reduction Act (IRA), as well as significantly lower sales freight costs, which fell by roughly half to $0.017 per watt. Furthermore, warehouse costs were reduced by $22 million sequentially. Adjusted EBITDA came in at $520 million (a 50% margin), beating the top end of the company's previously provided preview range. Net income surged 65% year-over-year to $347 million, or $3.22 per diluted share. First Solar ended the quarter with a fortress balance sheet, boasting a net cash position of $2.0 billion.

Strong Bookings and Pricing Discipline

Despite ongoing macroeconomic and trade policy uncertainties, First Solar's demand pipeline remains incredibly robust. Since the previous earnings call, the company secured 1.9 gigawatts (GW) of gross bookings. Excluding domestic volume in India, First Solar booked 1.4 GW into its core U.S. utility-scale market at a healthy average selling price (ASP) of approximately $0.35 per watt. Notably, half of this recently booked volume sits out in 2029, demonstrating long-term customer commitment. First Solar ended the first quarter with a massive contracted backlog of 47.9 GW, representing an aggregate transaction price of $14.4 billion, stretching through 2030. Management noted they are taking a highly selective approach to incremental U.S. bookings as they await regulatory clarity on the pending Section 232 polysilicon derivatives tariff decision, which could materially alter domestic supply-demand dynamics.

Technology Rollout: CURE and Perovskites

First Solar successfully completed the launch of its next-generation CURE technology at its Perrysburg, Ohio facility. Extensive testing has validated that CURE will deliver superior bifaciality, temperature coefficients, and degradation profiles, yielding up to 8% more lifetime specific energy than competing crystalline silicon TOPCon modules. The company plans to replicate CURE across its Series 6 and Series 7 manufacturing fleet through 2028. Management noted that if achieved, this rollout supports the potential realization of up to $600 million in additional revenue from technology "adjusters" already embedded in its existing backlog. Looking further out, First Solar confirmed it is developing a 1 GW pilot line for next-generation perovskite thin-film technology, which is slated to be operational in 2027.

Geopolitical Strategy and IP Enforcement

First Solar’s strategic focus on supply chain independence continues to pay dividends. In India, the company sold a record 1 GW of modules in the quarter as the local policy framework—including domestic content requirements—increasingly favors vertically integrated manufacturers. In the United States, First Solar is aggressively defending its intellectual property. The U.S. International Trade Commission (ITC) recently instituted a Section 337 investigation into respondents representing a significant share of TOPCon modules currently imported into the U.S. that allegedly infringe on First Solar's patents. An initial determination is expected within 11 months. Management reiterated its full-year 2026 guidance, noting that its international facilities in Malaysia and Vietnam are running at reduced utilization as the company awaits clarity on U.S. trade policies before committing to import strategies for those modules.
