SEC filingFirst Solar's revenue grew 24% to $5.2B in 2025, but gross margin contracted to 40.6% due to cost pressures and sales mix shift.
First Solar is America's leading PV solar technology and manufacturing company and the world's largest thin film PV solar module manufacturer. It is the only U.S.-headquartered company among the world's largest solar manufacturers. The company focuses on providing a competitive, high-performance, and responsibly produced alternative to conventional crystalline silicon PV solar modules. Its modules are produced using a fully integrated, continuous process that does not rely on Chinese crystalline silicon supply chains.
The Business section describes a single reportable segment: the Modules Business, which involves the design, manufacture, and sale of CdTe solar modules. No other segments are disclosed; the company's revenue is generated entirely from module sales.
First Solar manufactures two primary product lines: the Series 6 Plus module (approximately 4ft x 6ft) and the Series 7 module (approximately 4ft x 7ft with a steel back rail mounting structure). At the end of 2025, average power output was 464 watts for Series 6 Plus and 532 watts for Series 7. The company's CdTe thin film technology provides advantages including a superior temperature coefficient, superior spectral response in humid environments, better partial shading response, and immunity to cell cracking. The modules are warranted to produce at least 98% of labeled power output in the first year, with degradation factor coverage up to 30 years.
First Solar sells directly to system developers, independent power producers, utilities, commercial and industrial companies, large corporate energy buyers, and other system owners and operators. In 2025, the majority of sales were to customers with projects in the United States. The U.S. market accounted for 96% of net sales. Key customer concentration: Silicon Ranch Corporation and NextEra Energy each accounted for 10% or more of modules business net sales. The company also focuses on markets with high insolation, humid environments, responsible sourcing demand, and supportive policy environments, such as India.
The solar energy sector is highly competitive. First Solar primarily competes with crystalline silicon module manufacturers, most of which are linked to China. Competition is based on sales price per watt, influenced by module attributes such as wattage, energy yield, degradation, sustainability, and reliability. Competitors may have access to sovereign capital and operate at minimal margins. The company also competes on responsible sourcing and supply chain due diligence. Competition is further shaped by evolving federal policies, domestic content requirements, and foreign entity restrictions.
First Solar's strategy is built on five pillars: (1) Advanced Module Technology — leveraging CdTe thin film advantages and maintaining world record cell efficiencies (23.1% cell, 19.9% module aperture area). (2) Manufacturing Process and Distributed Manufacturing Presence — operating high-throughput, automated facilities in the U.S., Malaysia, Vietnam, and India with a continuous flow process. (3) Research and Development — vertically integrated R&D focusing on improving wattage, energy yield, durability, and manufacturing efficiencies, including tandem technology development. (4) Responsible Solar — ensuring no components from Xinjiang, achieving the smallest carbon footprint and fastest energy payback, and recycling over 90% of module materials. (5) Financial Stability — funding growth through operations and maintaining appropriate debt levels to offer meaningful warranties and strategic optionality.
As of December 31, 2025, First Solar had approximately 7,900 associates (full and part-time), with the majority located in the United States, Malaysia, India, and Vietnam. The company follows a pay-for-performance model, offers competitive compensation and benefits, and emphasizes career development, mentorship, and inclusive culture. Except for associates in Vietnam (represented by Vietnam General Confederation of Labor) and Sweden (represented by Engineers of Sweden), no associates are covered by collective bargaining agreements.
First Solar's net sales rose 24% year-over-year to $5.2 billion in 2025, primarily driven by a 24% increase in module volume sold to third parties. Gross profit increased 14% to $2.1 billion, but gross margin contracted 3.6 percentage points to 40.6% from 44.2% in 2024. The margin decline was attributed to a sales mix shift toward more U.S.-produced modules, higher warehousing costs, additional duties and tariffs, and increased logistics charges. These headwinds were partially offset by a $601.8 million reduction in cost of sales from higher recognition of Section 45X advanced manufacturing production credits. Operating margin decreased to 30.6% from 33.2%, reflecting the gross margin pressure and higher selling, general and administrative expenses (up 8% due to credit losses and legal costs) and research and development expenses (up 22% from headcount and facility investments).
First Solar operates as a single operating segment focused on the design, manufacture, and sale of CdTe solar modules. The company's third-party customer base includes system developers, independent power producers, utilities, and commercial entities. Substantially all sales were denominated in U.S. dollars, and two customers (Silicon Ranch Corporation and NextEra Energy) each accounted for 10% or more of net sales. The segment's performance mirrors the consolidated results, with revenue growth driven by volume and margin impacted by cost mix.
Management provided capital expenditure guidance of $0.8 billion to $1.0 billion for 2026, covering the construction of a sixth U.S. manufacturing facility (expected to commence operations in H2 2026), R&D investments, and equipment upgrades. The company expects to continue benefiting from Section 45X tax credits, with an estimated credit of ~17 cents per watt for U.S.-produced modules. As of December 31, 2025, First Solar had a contracted backlog of 50.1 GW with an aggregate transaction price of $15.0 billion, with revenue recognition expected through 2030. Potential additional revenue of up to $0.6 billion from price adjustments for future module technology improvements, largely in 2027-2028, was also noted. The company remains focused on cost competitiveness, technology roadmap (CuRe, perovskite), and navigating trade policy uncertainties.
As of December 31, 2025, First Solar held $2.80 billion in cash and cash equivalents and $51.8 million in marketable securities, totaling $2.85 billion in liquid assets. The company's total debt principal was $498.8 million, net of $0.2 million unamortized issuance costs, with a current portion of $216.0 million. Shareholders' equity stood at $9.54 billion, up from $7.98 billion a year earlier, driven by net income of $1.53 billion. Inventory totaled $974.2 million (current $736.7 million; noncurrent $237.5 million), a decrease from $1.36 billion in 2024.
First Solar reported a contracted backlog of 50.1 GW as of December 31, 2025, with an aggregate transaction price of $15.0 billion, expected to be recognized as revenue through 2030. Deferred revenue was $1.82 billion, down $220.4 million from 2024, due to revenue recognition on advance payments and contract terminations. The company also disclosed $79.4 million in product warranty liabilities, $146.0 million for solar module collection and recycling obligations, and $2.2 million in contingent consideration related to the Evolar acquisition.
No share repurchases or dividends were reported for 2025. First Solar issued $370.5 million in debt and repaid $473.4 million, resulting in a net debt reduction of $102.9 million. Capital expenditures totaled $869.9 million, representing 16.7% of net sales ($5.22 billion). The company purchased $5.0 million of restricted marketable securities to fund module collection and recycling obligations.
The notes do not provide segment-level financial data; First Solar operates as a single reporting unit (modules business). Geographic mix is not quantified in the notes, though revenue recognition policies note sales occur upon delivery to customer-specified locations. The company's net sales were concentrated among a limited number of customers.
First Solar faces significant regulatory and geopolitical risks. The IRA's Section 45X advanced manufacturing production credit (approx. $0.17/watt) is a critical financial benefit, but the One Big Beautiful Bill Act (OBBBA) of July 2025 curtailed certain energy tax credits, creating uncertainty about future benefits. Trade policy is highly volatile: IEEPA tariffs were ruled unlawful by the Supreme Court in February 2026 and replaced by Section 122 tariffs (up to 15% for 150 days). AD/CVD investigations on solar imports from Cambodia, Malaysia, Thailand, Vietnam, India, Indonesia, and Laos are ongoing, with final determinations in some cases. India's ALMM requirements and import duties (40% on modules) add complexity. China's export controls on tellurium could disrupt supply.
Key raw materials (CdTe, tellurium, glass) are single- or limited-sourced, creating vulnerability. China's export controls on tellurium are a specific new risk. Manufacturing equipment is customized and sole-sourced, posing disruption risks. The company is expanding domestic capacity by ~4 GW, including a new facility in South Carolina (expected H2 2026), which carries execution risk.
Intense competition from crystalline silicon manufacturers, especially in China, with structural overcapacity and pricing pressure. Competitors may operate at negative margins for sustained periods. New technologies (TOPCon, bifacial, n-type) could erode First Solar's competitive position.
Product quality issues with Series 7 modules (2023-2024) resulted in a $50M warranty liability, with potential losses of $35M-$75M. A legal dispute with BP/Lightsource involves $323.6M in termination payments and $175M in counterclaims. Patent infringement lawsuits against JinkoSolar, Canadian Solar, and others (including a USITC petition) could be costly and distract management. Customer concentration and contract breaches remain risks.
Failure to execute technology roadmap (e.g., CuRe program) could render products uncompetitive. Interest rate increases could reduce customer financing and demand. Cybersecurity and AI risks are noted but not quantified. Climate-related physical risks to manufacturing operations are acknowledged.
First Solar generated $2.0 billion in operating cash flow for FY2025, up 25% from $1.6 billion in FY2024. Net income was $1.5 billion, resulting in a CFO-to-net-income ratio of 1.33, indicating strong cash conversion. Capital expenditures of $1.1 billion were moderate relative to CFO, yielding free cash flow of $0.9 billion. The company did not repurchase shares or pay dividends, retaining all FCF for reinvestment. No significant working capital swings or one-time items were noted in the provided excerpt.
