•Net sales for 2024 increased by 27% to $4.2 billion compared to $3.3 billion in 2023. The increase in net sales was primarily driven by an increase in the volume of modules sold to third parties and an increase in termination payments associated with certain customer contract terminations in the U.S., India, and Europe, partially offset by a reduction in revenue related to manufacturing issues affecting certain Series 7 modules manufactured in 2023 and 2024. We currently believe the primary causes of the issues have been identified and we have taken actions to address such issues.

Solar energy is one of the fastest growing forms of renewable energy with numerous benefits, including economic and speed of deployment, that make it an attractive complement to or substitute for traditional forms of energy generation. In recent years, the cost of producing electricity from PV solar power systems has decreased to levels that are competitive with or below the wholesale price of electricity in many markets. Other technological developments in the renewable energy industry, such as the advancement of energy storage capabilities, have further enhanced the prospects of solar energy as an alternative to traditional forms of energy generation. As a result of these and other factors, worldwide solar markets continue to develop and expand. Government incentive programs, such as the IRA discussed previously, have contributed to this momentum by providing solar module manufacturers, project developers, and project owners with various incentives to accelerate the deployment of solar power generation. For more information about these incentive programs, see Item 1. “Business – Incentive Programs.”

Supply and Demand. As a result of the market opportunities described above, we recently commenced production of Series 7 modules at our first manufacturing facility in Alabama and are in the process of expanding our manufacturing capacity, including the construction of our fifth U.S. manufacturing facility, which is expected to commence operations in the second half of 2025. We continue to evaluate opportunities for future expansion worldwide. We believe manufacturers of solar cells and modules, particularly those in China, have significant installed production capacity, relative to global demand, and the ability for additional capacity expansion. Accordingly, we believe the solar industry may experience periods of structural imbalance between supply and demand, which could lead to periods of pricing volatility. Further, demand for solar energy in key markets, such as the United States and India, may be affected by the nature and extent of commitments to the renewable energy transition at the local and global levels. For example, certain large oil and gas and energy companies have experienced investor pressure to pursue returns commensurate with those currently associated with fossil fuel projects, where returns have become easier as fossil fuel prices have rebounded since the COVID-19 pandemic. Notwithstanding these considerations, utility and corporate demand for clean energy, and overall electric load growth, especially as a result of AI-driven data center demand, continue to increase. Internationally, given the combination of (i) a European Union market captured by Chinese solar modules, which pricing is at levels near or below manufacturing costs, (ii) an India market effectively closed to Southeast Asian finished goods, (iii) the uncertain U.S. policy environment following the 2024 U.S. elections, and (iv) a supply and demand imbalance for Southeast Asian product, we have decided to reduce production output of our Series 6 modules at our manufacturing facilities in Malaysia and Vietnam by a combined total of 1 GW in 2025. In light of such market realities, we continue to advocate for industrial and trade policies that provide a level playing field for domestic manufacturers of solar cells and modules. We also continue to focus on our strategies and points of differentiation, which include our advanced module technology, our manufacturing process and distributed manufacturing presence, our R&D capabilities, our commitment to responsible solar, and our financial stability.

Further, even on an unsubsidized basis, utility-scale PV solar is cost competitive with conventional forms of energy generation, including natural gas and nuclear, and is significantly faster to deploy than a five-year natural gas project development timeline or a much longer nuclear project timeline.

Pricing Competition. The solar industry has been characterized by intense pricing competition, both at the module and system levels. This competition may result in an environment in which pricing falls rapidly, which could potentially increase demand for solar energy solutions but constrain the ability for module manufacturers and project developers to sustain meaningful and consistent profitability. Our results of operations could be adversely affected if competitors reduce pricing below their costs, bid aggressively low prices for module sale agreements, or are able to operate at minimal or negative operating margins for sustained periods of time. For certain of our competitors, including many in China, these practices may be enabled by their direct or indirect access to sovereign capital or other forms of state support. Although module average selling prices in many global markets continue to decline, recent module pricing in the United States, our primary market, has been relatively stable due, in part, to the demand for domestically manufactured modules as a result of the IRA.

Diverse Offerings. We face intense competition from manufacturers of crystalline silicon solar modules and other emerging technologies. Solar module manufacturers compete with one another on sales price per watt, which may be influenced by several module value attributes, including energy yield, wattage (through a larger form factor or an improved conversion efficiency), degradation, sustainability, and reliability. Sales price per watt may also be influenced by warranty terms, customer payment terms, and/or module content attributes. We believe that utility-scale solar will continue to be a compelling offering and will continue to represent an increasing portion of the overall electricity generation mix. However, this focus on utility-scale module offerings exists within a current market environment that includes rooftop and distributed generation solar, which may influence our future offerings.

•Bifacial. While conventional solar modules are monofacial, meaning their ability to produce energy is a function of direct and diffuse irradiance on their front side, most module manufacturers offer bifacial modules that also capture diffuse irradiance on the back side of a module. Bifaciality compromises nameplate efficiency, but by converting both front and rear side irradiance, such technology may improve the overall energy production of a module relative to nameplate efficiency when applied in certain applications, which could lower the overall LCOE of a system when compared to systems using monofacial solar modules. We recently began commercial production of bifacial solar modules at certain of our manufacturing facilities and delivered our first bifacial modules to customers. Our bifacial module features an innovative transparent back contact which, in addition to converting both front and rear side irradiance, allows infrared light to pass through rather than be absorbed as heat. This design lowers the operational temperature of the module, resulting in a higher energy yield.

•CuRe. Our CuRe program is intended to improve our current semiconductor structure by replacing copper with certain other elements that are expected to enhance module performance by improving its bifaciality characteristics, improving its temperature coefficient, and improving its warranted degradation. As a result of these performance improvements, our PV solar modules are expected to produce more energy in real- world operating conditions over their estimated useful lives than crystalline silicon modules with the same nameplate capacity. In May 2024, we achieved a new world record CdTe research cell conversion efficiency of 23.1%, which was based on our CuRe program and certified by the U.S. Department of Energy’s National Renewable Energy Laboratory. We commenced a limited commercial production run of modules employing our CuRe technology in late 2024 and intend to begin a phased replication of the technology across our fleet in the first quarter of 2026.

Product Efficiencies. The efficiencies gained from the vertical integration of our manufacturing model and our cost management initiatives allow us to compete favorably in markets where pricing for modules and systems is highly competitive. Our cost competitiveness is based in large part on our advanced thin film semiconductor technology, module wattage, proprietary manufacturing process (which enables us to produce a CdTe module in a matter of hours using a continuous and highly automated industrial manufacturing process, as opposed to a batch process), and focus on operational excellence. In addition, our CdTe modules use approximately 2% to 3% of the amount of semiconductor material that is used to manufacture conventional crystalline silicon solar modules. The cost of polysilicon is a significant driver of the manufacturing cost of crystalline silicon solar modules, and the timing and rate of change in the cost of silicon feedstock and polysilicon could lead to changes in solar module pricing levels.

Energy Performance. In many climates our solar modules provide certain energy production advantages relative to competing crystalline silicon solar modules. As a result, our solar modules can produce more annual energy in real-world operating conditions than conventional crystalline silicon modules with the same nameplate capacity. For more information about these advantages, see Item 1. “Business – Business Strategy.” Additionally, we warrant that our solar modules will produce at least 98% of their labeled power output rating during the first year, with the warranty coverage reducing by a degradation factor that is generally between 0.3% and 0.5%, depending on the module series, every year thereafter throughout the limited power output warranty period of up to 30 years.

Our business is evolving worldwide and is shaped by the varying ways in which our offerings can be compelling and economically viable solutions to energy needs in various markets. In addressing electricity demands, we are focused on providing utility-scale module offerings in key geographic markets that we believe have a significant need for mass-scale PV solar electricity, including markets throughout the United States and India. We closely evaluate and monitor the appropriate level of resources required to support such markets and their associated sales opportunities. When deployed in utility-scale applications, our modules provide energy at a lower LCOE compared to traditional forms of energy generation, making them an attractive alternative to or replacement for aging fossil fuel-based generation resources. Accordingly, future retirements of aging energy generation resources represent a significant increase in the potential market for solar energy.

Demand for our PV solar module offerings depends, in part, on market factors outside our control. For example, many governments have proposed or enacted policies or incentive programs intended to encourage renewable energy investments to achieve decarbonization objectives and/or establish greater energy independence. While we compete in markets that do not require solar-specific government subsidies or incentive programs, our net sales and profits remain subject to variability based on the availability and size of government subsidies and economic incentives. Adverse changes in these factors could increase the cost of utility-scale systems, which could reduce demand for our solar modules. Recent developments to government incentive programs include the following:

•United States. In August 2022, the previous U.S. President signed the IRA into law, which was intended to accelerate the country’s energy transition. Among other things, the financial incentives provided by the IRA have significantly increased demand for modules manufactured in the United States. Accordingly, the demand for these solar modules is expected to increase domestic manufacturing in the near term, which may result in localized supply chain constraints and periods of inflationary pricing for certain of our key raw materials. The financial incentives provided by the IRA have also increased demand for solar modules in general due to the incremental tax credit available for the qualified production of clean hydrogen that is powered by renewable resources. Given the complexities of the IRA, we continue to evaluate the extent of benefits available to us, which we expect will favorably impact our results of operations in future periods. For example, we currently expect to qualify for the advanced manufacturing production credit under Section 45X of the IRC, which provides certain specified benefits for solar modules and solar module components manufactured in the United States and sold to third parties. See Note 9. “Government Grants” and Note 18. “Income Taxes” to our consolidated financial statements for discussion of our expectation of the financial benefits available to us under the IRA and developments to technical guidance and regulations, respectively. Also, the new presidential administration and control of the U.S. Congress present uncertainty as to the continued availability of such benefits. For example, on January 20, 2025, the U.S. President issued the executive order entitled, “Unleashing American Energy,” which, among other things, indicated a lack of support for federal funding of certain solar and solar-related projects. For more information about certain risks associated with the benefits available to us under the IRA, see Item 1A. “Risk Factors – We have received and expect to continue to receive certain financial benefits as a result of tax incentives provided by the Inflation Reduction Act of 2022. If these financial benefits vary significantly from our assumptions, our business, financial condition, and results of operations could be adversely affected.”

Further, on July 4, 2025, the U.S. President signed H.R.1 into law, commonly referred to as the “One Big Beautiful Bill,” which significantly curtails the availability of certain energy tax credits. H.R.1 includes accelerating the termination of the clean electricity ITC and PTC in relation to solar and restricting tax credits if a taxpayer employs certain products and components produced by a supplier with ties to a FEOC. H.R.1 also severely limits Section 45X tax credit eligibility for products manufactured by, or with material assistance from, a FEOC. For more information about certain risks associated with the benefits available to us under the IRA, see Item 1A. “Risk Factors – We have received and expect to continue to receive certain financial benefits as a result of tax incentives enacted by the Inflation Reduction Act of 2022 and amended by the One Big Beautiful Bill Act of 2025.

•China. In early February 2025, China announced that it would tighten export controls for five key minerals, including products containing tellurium; tellurium is one of the main components of our CdTe module production process. Although tellurium and products containing tellurium are sourced globally, China is a major global producer of tellurium and products containing tellurium. Exporters of tellurium and related products may be required to obtain a license from the Chinese Ministry of Commerce. Since these export controls came into effect, we have assembled a cross-functional team to interpret the export controls, analyze how they may impact First Solar’s module production process. We have and intend to continue applying for export licenses where appropriate, as well as continuing to implement other strategic alternatives such as leveraging our alternative suppliers to mitigate potential adverse impacts from these export controls. For more information about this development, see Item 1A. “Risk Factors – A disruption in our supply chain for CdTe, tellurium, products containing tellurium, or other key raw materials, or equipment could interrupt or impair our ability to manufacture solar modules and could adversely impact our profitability and long-term growth prospects.”

For more information about the ALMM, see Item 1A. “Risk Factors – The modification, reduction, elimination, or expiration of government subsidies, economic incentives, eligibility limitations, tax incentives, renewable energy targets, and other support for on-grid solar electricity applications, or the impact of other public policies, such as tariffs or other trade remedies imposed on solar cells and modules or related raw materials or equipment, have, and in the future could, negatively impact demand and/or price levels for our solar modules and limit our growth or lead to a reduction in our net sales or increase our costs, thereby adversely impacting our operating results.”

Previous wording

Our ability to provide solar modules on economically attractive terms is also affected by the availability and cost of logistics services associated with the procurement of raw materials or equipment used in our manufacturing process and the shipping, handling, storage, and distribution of our modules. To mitigate certain logistics costs, we employ commercial contract structures that provide additional consideration to us if the cost of logistics services, excluding demurrage and detention, exceeds defined thresholds. We may also adjust our shipping plans to include additional lead times for module deliveries and/or utilize our network of U.S. distribution centers to mitigate logistics costs. Additionally, our manufacturing capacity expansions are expected to bring production activities closer to customer demand, further mitigating our exposure to the cost of ocean freight.

We generally price and sell our solar modules on a per watt basis. As of December 31, 2024, we had entered into contracts with customers for the future sale of 68.5 GW of solar modules for an aggregate transaction price of $20.5 billion, which we expect to recognize as revenue through 2030 as we transfer control of the modules to our customers. This volume and transaction price exclude contracts with customers in India for which payment has not been fully secured. This volume includes contracts for the sale of 37.1 GW of solar modules with anticipated price adjustments for future module technology improvements, including enhancements to certain energy related attributes. Based on these potential improvements, the contracted module volume as of December 31, 2024, the expected timing of such improvements being incorporated into our manufacturing process, and the expected timing of module deliveries, such adjustments, if realized, could result in additional revenue of up to $0.7 billion, the majority of which would be recognized between 2026 and 2028. In addition to these price adjustments, certain of our contracts with customers may include favorable price adjustments associated with sales freight in excess of defined thresholds and/or favorable or unfavorable price adjustments associated with changes to (i) certain commodity prices, (ii) the module wattage committed for delivery, and (iii) the volume of modules sold that meet certain U.S. domestic content requirements. As a result, the revenue recognized from such contracts may increase or decrease in future periods relative to the original transaction price.

We monitor our modules’ expected performance through quality and reliability testing, as well as actual performance in certain field installation sites. Any declines in the expected performance attributes of our modules could adversely impact our financial results due to declines in the average selling prices of our modules and additional margin compression. For example, the recently identified manufacturing issues affecting certain Series 7 modules may adversely impact the average selling prices of our modules or the carrying value of our inventories. These manufacturing issues may also increase product warranty claims by our customers to resolve the premature power loss in affected modules. The remediation of any identified issues in our manufacturing process may result in increased costs as we resolve the identified issues. Any future manufacturing issues, including any additional commitment made by us to remediate the affected modules beyond our limited warranty, could also adversely impact our reputation, financial position, operating results, and cash flows. We may also be subject to certain other risks and uncertainties surrounding module performance as described in Item 1A. “Risk Factors – Problems with product quality or performance may cause us to incur significant and/or unexpected contractual damages and/or warranty and related expenses, damage our market reputation, and prevent us from maintaining or increasing our market share.”
