Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations

The following discussion and analysis of our financial condition and results of operations should be read in conjunction with our consolidated financial statements and the related notes thereto included in this Annual Report on Form 10-K. In addition to historical financial information, the following discussion and analysis contains forward-looking statements that involve risks, uncertainties, and assumptions as described under the “Note Regarding Forward-Looking Statements” that appears earlier in this Annual Report on Form 10-K. Our actual results could differ materially from those anticipated by these forward-looking statements as a result of many factors, including those discussed under Item 1A. “Risk Factors,” and elsewhere in this Annual Report on Form 10-K. This discussion and analysis does not address certain items in respect of the year ended December 31, 2023. See Item 7. “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in our Annual Report on Form 10-K for the year ended December 31, 2024 for comparative discussions of our results of operations and liquidity and capital resources for the years ended December 31, 2024 and 2023.

Executive Overview

We are America’s leading PV solar technology and manufacturing company. The only U.S.-headquartered company among the world’s largest solar manufacturers, First Solar is focused on competitively and reliably enabling power generation needs with our advanced, uniquely American thin film PV technology. Developed at R&D labs in California and Ohio, our technology provides a competitive, high-performance, and responsibly produced alternative to conventional crystalline silicon PV solar modules. Our PV solar modules are produced using a fully integrated, continuous process that does not rely on Chinese crystalline silicon supply chains.

We are the world’s largest thin film PV solar module manufacturer and the largest PV solar module manufacturer in the Western Hemisphere. We recently commenced operations at our fourth and fifth manufacturing facilities in the United States and completed the expansion of our manufacturing footprint at our existing facilities in Ohio. We are in the process of further expanding our domestic manufacturing capacity, including the construction of our sixth U.S. manufacturing facility to onshore final production processes for modules initiated by our international fleet, which is expected to commence operations in the second half of 2026. Our global manufacturing footprint spans the United States, India, Malaysia, and Vietnam.

Certain of our financial results and other key operational developments for the year ended December 31, 2025 include the following:

•Net sales for 2025 increased by 24% to $5.2 billion compared to $4.2 billion in 2024. The increase in net sales was primarily driven by an increase in the volume of modules sold to third parties.

51

Table of Contents

•Gross profit as a percentage of net sales decreased 3.6 percentage points to 40.6% in 2025 from 44.2% in 2024. The decrease was primarily driven by higher costs related to a sales mix that included more U.S.-produced modules, higher warehousing costs, additional duties and tariff costs, and higher logistics charges, partially offset by the recognition of higher advanced manufacturing production credits under Section 45X of the IRC.

•During 2025, we commenced production of Series 7 modules at our new manufacturing facility in Louisiana. During 2025, we produced 16.1 GW and sold 17.5 GW of solar modules.

•In June 2025 and July 2025, we entered into two separate agreements for the sale of $701.9 million of Section 45X tax credits we generated during 2025 for aggregate cash proceeds of $668.1 million. We received the full cash proceeds during the year ended December 31, 2025.

•In October 2025, we entered into two separate agreements for the sale of $699.7 million of Section 45X tax credits we generated during 2025 for aggregate cash proceeds of $668.2 million. We received initial cash proceeds of $573.0 million during the year ended December 31, 2025, and expect to receive the remaining cash proceeds of $95.2 million during the first quarter of 2026.

•During 2025, we terminated various master supply agreements with BP Solar Holding LLC and its affiliate Lightsource Renewable Energy Trading, LLC due to the customers’ failure to cure several breaches of their contractual obligations. These terminations triggered certain contractual termination payment provisions amounting to $384.6 million, of which we recognized $61.0 million as revenue for advance payments previously received from the customer. In September 2025, we filed a complaint with the Supreme Court of the State of New York seeking relief and demanding payment from these customers for the remaining termination payments along with certain other receivables for solar modules previously delivered.

Market Overview

Solar energy is one of the fastest growing forms of renewable energy with numerous benefits, including economic benefits and speed of deployment, which make it an attractive complement to or substitute for traditional forms of energy generation. In recent years, the cost of electricity from PV solar power systems has generally been competitive with or below other forms of generation. 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 attractive complement 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 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.” Although we compete in markets that do not require solar-specific government incentive programs, our net sales and profits remain subject to variability based on the availability and size of these programs, including tax and production incentives, renewable portfolio standards, and other incentive programs intended to stimulate economies, achieve decarbonization initiatives, and/or establish greater energy independence. Such programs continue to influence the demand for PV solar energy around the world.

Supply and Demand

As a result of the market opportunities described above, we recently commenced operations at our fourth and fifth manufacturing facilities in the United States and completed the expansion of our manufacturing footprint at our existing facilities in Ohio. We are in the process of further expanding our domestic manufacturing capacity, including the construction of our sixth U.S. manufacturing facility to onshore final production processes for modules initiated by our international fleet, which is expected to commence operations in the second half of 2026. We believe

52

Table of Contents

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. Notwithstanding these considerations, utility and corporate demand for energy and overall electric load growth, especially as a result of AI-driven data center demand, continue to increase. 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.

Given the combination of (i) a European market captured by Chinese solar modules, where pricing is at levels near or below manufacturing costs, (ii) an Indian market effectively closed to Southeast Asian products, (iii) a general supply and demand imbalance for Southeast Asian products, and (iv) certain tariffs on modules imported into the United States, we have reduced production of Series 6 modules at our international manufacturing facilities.

In light of these market realities, we continue to advocate for industrial and trade policies that provide a level playing field for manufacturers of solar cells and modules. We also continue to focus on our strategies and points of differentiation, which include our proprietary advanced module technology, our manufacturing process and distributed manufacturing presence, our localized supply chain, our R&D capabilities, our commitment to responsible solar, and our financial stability.

Pricing Competition

The solar industry continues to be 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. Module average selling prices in many global markets have declined. However, recent module pricing in the United States, our primary market, has remained stable due, in part, to the rising demand for domestically manufactured modules as a result of the IRA, energy tax credit eligibility restrictions (including foreign-entity-related limitations) as amended by the OBBBA, and tariffs on modules imported into the United States.

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 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.

We continue to devote significant resources to support the implementation of our technology roadmap and improve the energy output of our modules. In the course of our R&D activities, we explore various technologies in our efforts to sustain competitive differentiation of our modules. Such technologies include the development of bifacial modules, the implementation of our CuRe program, and the ongoing R&D of a viable and commercially scalable perovskite product.

•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 power, but by converting both front and back side irradiance, such technology may improve the overall energy production of a module relative to nameplate power when applied in certain applications, which could lower the overall LCOE of a system when compared to systems using monofacial solar modules.

•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 power. In late 2024, we commenced a limited commercial production run of modules employing our CuRe technology, and during the first half of 2025, we sold our first CuRe modules to customers. Beginning in the first quarter of 2026, we intend to permanently convert one of our Ohio facilities to CuRe, followed by a phased replication of the technology across certain manufacturing facilities within our fleet.

•Perovskite. We continue to research and develop our thin-film semiconductor technology, with a focus on the use of perovskite thin films. Perovskites have the potential to significantly increase the efficiency and reduce the cost of PV solar modules either through single-junction or potentially multi-junction devices. Supported by the associates at our California and European Technology Centers, we continue to advance our work on improving both the efficiency and stability of this technology in developing a commercially scalable perovskite product. Our investment in this technology also includes the construction of a dedicated perovskite development line at our Ohio facility.

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 energy in real-world operating conditions than conventional crystalline silicon modules with the same nameplate power. For more information about these advantages, see Item 1. “Business – Business Strategy.” Additionally, we generally warrant that our solar modules will produce at least 98% of their labeled power output rating during the first year, with the warranty coverage

54

Table of Contents

reducing by a degradation factor every year thereafter throughout the limited power output warranty period of up to 30 years.

While our modules are generally competitive in cost, reliability, and performance attributes, there can be no guarantee such competitiveness will continue to exist in the future to the same extent, or at all. Any declines in the competitiveness of our products could result in declines in the average selling prices of our modules and additional margin compression. Accordingly, we continue to focus on enhancing the competitiveness of our solar modules through our module technology and cost reduction roadmaps.

Certain Trends and Uncertainties

We believe that our business, financial condition, and results of operations may be favorably or unfavorably impacted by the following trends and uncertainties. See Item 1A. “Risk Factors” and elsewhere in this Annual Report on Form 10-K for discussions of other risks that may affect us.

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 our key markets. In addressing electricity demands, we are focused on providing utility-scale module offerings in markets that we believe have a significant need for mass-scale PV solar electricity, including markets primarily in 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.

Demand for our PV solar modules depends, in part, on certain 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 ongoing transition to clean energy. Among other things, the financial incentives provided by the IRA have significantly increased demand for modules manufactured in the United States. We 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. However, the current U.S. presidential administration and control of the U.S. Congress present uncertainty as to the continued availability of certain 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. 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. If these financial benefits vary significantly from our assumptions, our business, financial condition, and results of operations could be adversely affected.”

Demand for our PV solar modules also depends on domestic or international trade policies and government regulations, which may be proposed, revised, and/or enacted across short- and long-term time horizons with varying degrees of impact to our net sales, profit, and manufacturing operations. Changes in these policies and regulations could adversely impact the competitive landscape of solar markets, which could reduce demand for our solar modules. Recent revisions or proposed changes to trade policy and government regulations include the following:

•United States. In April 2025, the U.S. President imposed a 10% “baseline” reciprocal tariff on nearly all U.S. trading partners, and additional, higher reciprocal tariffs on certain countries. Effective May 14, 2025, the United States entered into an agreement with China to lower the reciprocal tariff rate to 10% for 90 days. This agreement has since been extended until November 10, 2026. As it pertains to the countries where we manufacture solar modules, IEEPA tariffs applied to Vietnam (20%), India (25%), and Malaysia (19%). In August 2025, the U.S. President had imposed an additional 25% tariff on India over its purchases of Russian oil, resulting in an overall rate of 50%. On February 20, 2026, the U.S. Supreme Court ruled the IEEPA tariffs unlawful. President Trump responded immediately by revoking the IEEPA tariff actions and imposing new global tariffs pursuant to Section 122 of the Trade Act of 1974 (“Section 122”), which provides for tariffs up to 15% for a period of no more than 150 days. For more information about this development, 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.”

•United States. Effective June 4, 2025, the U.S. President increased tariffs on imported aluminum and steel articles under Section 232 from 25% to 50%. Effective August 1, 2025, the U.S. President imposed tariffs of 50% on copper under Section 232. Effective October 14, 2025, the U.S. President imposed tariffs of 10% on imported softwood timber and lumber products under Section 232. Further, on April 22, 2025, the U.S. Secretary of Commerce initiated an investigation to determine the effects on the national security of imports of processed critical minerals, as well as their derivative products, under Section 232; on July 1, 2025, the U.S. Secretary of Commerce initiated a Section 232 investigation to determine whether imports of polysilicon and its derivatives impair U.S. national security; and on September 2, 2025, the U.S. Secretary of Commerce initiated an investigation to determine the effects on the national security of imports of robotics and industrial machinery under Section 232. For more information about the context of these developments, 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.”

•China. In February 2025, China announced that it would tighten export controls for five key minerals, including products containing tellurium, which is one of the main components of our CdTe modules. 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 are generally required to obtain a license from the Chinese Ministry of Commerce. In October 2025, China expanded its rare earths export controls, adding new minerals to its restricted list and requiring foreign entities to obtain a license to export any products containing over 0.1% of rare earths from China or manufactured using China’s extraction, refining, magnet-making, or recycling technology. In November 2025, China announced it would delay imposition of the October 2025 export controls for one year. In February 2026, the U.S. President announced the creation of an approximately $12 billion stockpile of

56

Table of Contents

critical minerals for U.S. manufacturers in response to the potential supply chain disruptions as a result of Chinese export controls. We have assembled a cross-functional team to interpret the export controls and related developments and analyze how they may impact materials required for our module production. We have applied for and intend to continue applying for export licenses where appropriate, as well as continuing to implement other strategic alternatives, such as sourcing from other 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.”

•United States. In April 2024, the American Alliance for Solar Manufacturing Trade Committee, which includes First Solar, filed a set of AD/CVD petitions with the USDOC and the USITC to impose duties on certain unfairly traded solar products from Cambodia, Malaysia, Thailand, and Vietnam. Following final affirmative determinations by the USDOC and USITC that identified final subsidy rates of 534.67% to 3,403.96% for Cambodia, 14.64% to 168.8% for Malaysia, 263.74% to 799.55% for Thailand, and 68.15% to 542.64% for Vietnam, AD/CVD orders, including the assessment of countervailing duties and suspension of liquidation of such products, were issued on June 9, 2025. On July 17, 2025, the Alliance for American Solar Manufacturing and Trade filed another set of AD/CVD petitions with the USDOC and the USITC to impose duties on unfairly traded crystalline silicon solar products from India, Indonesia, and Laos. In addition to a range of alleged illegal subsidies, the petitioners identified dumping margins of 213.96% for India, 89.65% for Indonesia, and 245.79 to 249.09% for Laos. For more information about this development, 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.”

•India. The ALMM was introduced in 2021 as a non-tariff barrier to incentivize domestic manufacturing of PV modules by approving the list of models and manufacturers who can participate in certain solar development projects. The ALMM is approved by the MNRE, and any modifications to the ALMM and its application may affect future investments in solar module manufacturing in India. For example, in December 2024, the ALMM was amended to require nearly all solar development projects to use PV modules that contain domestically manufactured solar cells, which is expected to be effective for such projects completed on or after June 2026; in August 2025, the relevant list of qualifying entities was released, which included First Solar as an approved manufacturer. Further, in September 2025, the MNRE released draft amendments that would require nearly all solar development projects to use PV modules that contain domestically manufactured wafers, which is expected to be effective for such projects completed on or after June 2028; the proposed list was released at that time, which included First Solar as an approved manufacturer. In November 2025, the MNRE released a draft proposal that would increase the minimum efficiency of PV modules for manufacturers to be included in the ALMM beginning in 2027, which would potentially impact First Solar’s ability to sell modules within the Indian market. 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.”

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 use 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, 2025, we had entered into contracts with customers for the future sale of 50.1 GW of solar modules for an aggregate transaction price of $15.0 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 23.2 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, 2025, 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 $0.6 billion, the majority of which would be recognized in 2027 and 2028. In addition to these price adjustments, certain of our contracts with customers may include favorable or unfavorable price adjustments associated with changes to (i) sales freight in excess of defined thresholds, (ii) changes to certain commodity prices, (iii) the module wattage committed for delivery, (iv) the volume of modules sold that meet certain U.S. domestic content requirements, and (v) changes to certain tariff structures within a defined threshold, among other things. As a result, the revenue recognized from such contracts may increase or decrease in future periods relative to the original transaction price or may otherwise be impacted if a contract is canceled.

While our contracts with customers typically have certain firm purchase commitments and may require our customers to make payments to us if a contract is terminated in certain circumstances, those contract terms have in the past and may in the future be breached by our customers or subject to renegotiation. Among other things, these contract breaches and renegotiations have reduced, and may continue to reduce, the volume of modules sold under the relevant contracts and/or the extent of anticipated price adjustments for future module technology improvements, thereby reducing future sales of solar modules. Furthermore, our ability to subsequently resell solar modules sold under terminated and/or renegotiated contracts may be constrained by the project lead times of our customers, their required module specifications, or other factors. For example, on September 30, 2025, First Solar filed a complaint in the Supreme Court of the State of New York asserting that BP Solar Holding LLC and its affiliate Lightsource Renewable Energy Trading, LLC breached their contractual obligations with First Solar, having entered into various master supply agreements to purchase solar modules from First Solar and then refusing to pay the amounts owed under the purchase orders. For more information about this development, see Part I. Item 3. “Legal Proceedings.”

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 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. 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.”

We are in the process of expanding our domestic manufacturing capacity; this additional capacity, and any other potential investments to add to or otherwise modify our existing manufacturing capacity in response to market demand and competition, may require significant internal and possibly external sources of capital, and may be subject to certain risks and uncertainties described in Item 1A. “Risk Factors,” including those described under the headings “Our future success depends on our ability to effectively balance manufacturing production with market demand, effectively manage our cost per watt, and, when necessary, continue to build new manufacturing plants over time in response to market demand, all of which are subject to risks and uncertainties” and “If any future production lines are not built in line with committed schedules, it may adversely affect our future growth plans. If any future production lines do not achieve operating metrics similar to our existing production lines, our solar modules could perform below expectations and cause us to lose customers.”

Segment Overview

First Solar operates as one business, which involves the design, manufacture, and sale of CdTe solar modules, which convert sunlight into electricity. As such, we operate as a single operating segment. Our third-party customers include system developers, independent power producers, utilities, commercial and industrial companies, large corporate energy buyers, and other system owners and operators.

Net sales

We generally price and sell our solar modules on a per watt basis. During 2025, Silicon Ranch Corporation and NextEra Energy each accounted for 10% or more of our net sales, and the majority of our solar modules were sold to developers and operators of systems in the United States. Substantially all of our net sales during 2025 were denominated in U.S. dollars. We recognize revenue for module sales at a point in time following the transfer of control of the modules to the customer, which typically occurs upon delivery of the modules to the location specified in the terms of the underlying contract. The revenue recognition policies for module sales are further described in Note 2. “Summary of Significant Accounting Policies” to our consolidated financial statements.

Net sales increased by $1.0 billion in 2025 primarily due to a 24% increase in the volume of modules sold to third parties.

Cost of sales

Our cost of sales includes the cost of raw materials and components for manufacturing solar modules, such as glass, transparent conductive coatings, CdTe and other thin film semiconductors, laminate materials, connector assemblies, edge seal materials, and frames or back rails. In addition, our cost of sales includes direct labor for the manufacturing of solar modules and manufacturing overhead, such as engineering, equipment maintenance, quality and production control, and information technology. Our cost of sales also includes depreciation of manufacturing plant and equipment, facility-related expenses, environmental health and safety costs, and costs associated with logistics, warranties, and solar module collection and recycling (excluding accretion).

Cost of sales increased $750.6 million, or 32%, and increased 3.6 percentage points as a percent of net sales when comparing 2025 with 2024. The increase in cost of sales was driven by (i) higher costs of $651.6 million due to an increase in the volume of modules sold; (ii) higher production costs of $216.5 million, largely due to a higher sales mix of U.S.-produced modules and tariffs on raw materials; (iii) higher logistics costs of $173.1 million, which included detention and demurrage charges; (iv) higher warehousing costs of $130.7 million; and (v) tariffs on international modules imported into the United States of $94.4 million. These increases were partially offset by (vi) a higher sales mix of modules qualifying for the advanced manufacturing production credit under Section 45X of the IRC, which decreased cost of sales by $601.8 million.

Gross profit

Gross profit may be affected by various factors, including the selling prices of our modules, our manufacturing costs, the capacity utilization of our manufacturing facilities, and foreign exchange rates.

Income tax expense

Income tax expense or benefit, deferred tax assets and liabilities, and liabilities for unrecognized tax benefits reflect our best estimates of current and future taxes to be paid. We are subject to income taxes in both the United States and numerous foreign jurisdictions in which we operate, principally Singapore, Malaysia, Vietnam, and India. Significant judgments and estimates are required to determine our consolidated income tax expense. The statutory federal corporate income tax rate in the United States is 21%, and the tax rates in Singapore, Malaysia, Vietnam, and India are 17%, 24%, 20%, and 17%, respectively. In Malaysia, we have been granted a long-term tax holiday, scheduled to expire in 2027, pursuant to which substantially all of our income earned in Malaysia is exempt from income tax, conditional upon our continued compliance with certain employment and investment thresholds. In Vietnam, we have been granted a long-term tax incentive, scheduled to expire at the end of 2036, pursuant to which income earned in Vietnam is subject to reduced tax rates, conditional upon our continued compliance with certain revenue and R&D spending thresholds.

effects of tax law associated with the IRA, partially offset by a lower relative benefit from the long-term tax holiday in Malaysia and higher pretax income in the current year.

Liquidity and Capital Resources

As of December 31, 2025, we believe that our cash, cash equivalents, marketable securities, cash flows from operating activities, and contracts with customers for the future sale of solar modules will be sufficient to meet our working capital and capital expenditure needs for at least the next 12 months. In addition, as of December 31, 2025 we had availability under an unused $1.0 billion revolving credit facility, as well as various trade receivables factoring arrangements with financial institutions. In February 2026, we terminated the existing revolving credit facility and replaced it with a larger, $1.5 billion revolving facility. For more information about these facilities, see Note 12. “Debt.” To the extent we offer extended payment terms to customers, fail to collect trade receivables in a timely manner, or face other challenges in managing our working capital, we may be required to use our Credit Facility or other temporary sources of funding. As necessary, we also believe we will have adequate access to the capital markets. We monitor our working capital to ensure we have adequate liquidity, both domestically and internationally. We intend to maintain appropriate debt levels based upon cash flow expectations, our overall cost of capital, and expected cash requirements for operations, including near-term expansion activities in the United States. However, our ability to raise capital on terms commercially acceptable to us could be constrained if there is insufficient lender or investor interest due to company-specific, industry-wide, or broader market concerns. Any incremental debt financing could result in increased debt service expenses and/or restrictive covenants, which could limit our ability to pursue our strategic plans.

As of December 31, 2025, we had $2.9 billion in cash, cash equivalents, and marketable securities compared to $1.8 billion as of December 31, 2024. This increase was primarily driven by (i) proceeds from the sale of Section 45X tax credits and (ii) higher cash receipts from module sales, including advance payments for future sales, partially offset by (iii) increases in payments made to suppliers, (iv) purchases of property, plant and equipment for our U.S. facilities, (v) various operating expenditures, (vi) certain advance payments for raw materials, and (vii) repayment of debt. As of December 31, 2025 and 2024, $0.5 billion and $0.7 billion of our cash, cash equivalents, and marketable securities, respectively, were held by our foreign subsidiaries and were primarily based in U.S. dollar, Indian Rupee, and Euro denominated holdings. Our investment policy seeks to preserve our investment principal and maintain adequate liquidity to meet our cash flow requirements, while at the same time optimizing the return on our investments. Pursuant to such policy, we place our investments with a diversified group of high-quality financial institutions and limit the concentration of such investments with any one counterparty. We place significant emphasis on the creditworthiness of financial institutions and assess the credit ratings and financial health of our counterparty financial institutions when making investment decisions.

We use a variety of tax planning and financing strategies in an effort to ensure that our worldwide cash is available in the locations in which it is needed. If certain international funds were needed for our operations in the United States, we may be required to accrue and pay certain U.S. and foreign taxes to repatriate such funds. We maintain the intent and ability to permanently reinvest our accumulated earnings outside the United States, with the exception of certain subsidiaries for which applicable income taxes have been recorded as of December 31, 2025. In addition, changes to foreign government banking regulations may restrict our ability to move funds among various jurisdictions under certain circumstances, which could negatively impact our access to capital, resulting in an adverse effect on our liquidity and capital resources.

Although we compete in markets that do not require solar-specific government subsidies or incentive programs, such incentives continue to significantly influence the demand for PV solar energy around the world. Further, our net sales and profits remain subject to variability based on the availability and size of government subsidies and economic incentives. For example, the financial incentives provided by the IRA have significantly increased demand for modules manufactured in the United States, and we expect the benefits made available to us by the IRA to favorably impact our liquidity and capital resources in future periods. We expect to qualify for the advanced manufacturing production credit under Section 45X of the IRC, which provides certain specified benefits for solar

64

Table of Contents

modules and solar module components manufactured in the United States and sold to third parties. Such credit may be refundable by the IRS or transferable to a third party and is available from 2023 to 2032, subject to phase down beginning in 2030. Based on the current form factor of our modules, we believe we qualify for a credit of approximately 17 cents per watt for each module produced in the United States and sold to a third party. Accordingly, we expect the advanced manufacturing production credit will provide us with a significant source of funding throughout its remaining period.

In June 2025 and July 2025, we entered into two agreements for the sale of $701.9 million of Section 45X tax credits we generated during 2025 for aggregate cash proceeds of $668.1 million. We received the full cash proceeds during the year ended December 31, 2025. In October 2025, we entered into two agreements for the sale of $699.7 million of Section 45X tax credits we generated during 2025 for aggregate cash proceeds of $668.2 million. We received initial cash proceeds of $573.0 million during the year ended December 31, 2025, and expect to receive the remaining cash proceeds of $95.2 million during the first quarter of 2026. 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. If these financial benefits vary significantly from our assumptions, our business, financial condition, and results of operations could be adversely affected.” See Note 8. “Government Grants” to our consolidated financial statements for further information about government grants.

As a result of various market opportunities and increased domestic demand for our products, we recently commenced operations at our fourth and fifth manufacturing facilities in the United States and completed the expansion of our manufacturing footprint at our existing facilities in Ohio. We are in the process of further expanding our domestic manufacturing capacity, including the construction of our sixth U.S. manufacturing facility to onshore final production processes for modules initiated by our international fleet, which is expected to commence operations in the second half of 2026. We anticipate our investment in this U.S. facility to be approximately $0.3 billion. The capital expenditures necessary to expand our capacity may be financed, in part, by cash on hand, advance payments from customers for module sales in future periods, and the advanced manufacturing production credit described above.

During 2026, we expect to spend between $0.8 billion and $1.0 billion for capital expenditures, including the new facility mentioned above, investments in various R&D initiatives, and upgrades to machinery and equipment. These capital investments, and any other potential investments to implement our technology roadmap, may require significant internal and possibly external sources of capital and may be subject to certain risks and uncertainties described in Item 1A. “Risk Factors,” including those described under the headings “Our future success depends on our ability to effectively balance manufacturing production with market demand, effectively manage our cost per watt, and, when necessary, continue to build new manufacturing plants over time in response to market demand, all of which are subject to risks and uncertainties” and “If any future production lines are not built in line with committed schedules, it may adversely affect our future growth plans. If any future production lines do not achieve operating metrics similar to our existing production lines, our solar modules could perform below expectations and cause us to lose customers.”

We have committed and expect to continue to commit significant working capital to purchase various raw materials used in our module manufacturing process. Our failure to obtain raw materials and components that meet our quality, quantity, and cost requirements in a timely manner could increase our manufacturing costs or interrupt or impair our ability to manufacture our solar modules. Accordingly, we may enter into long-term supply agreements to mitigate potential risks related to the procurement of key raw materials and components, and such agreements may be noncancelable or cancelable with a significant penalty. For example, we have entered into long-term supply agreements for the purchase of certain specified minimum volumes of substrate glass for our PV solar modules. We have the right to terminate certain of these agreements upon payment of specified termination payments (which, in aggregate, are up to approximately $300 million as of December 31, 2025 and decline over the remaining supply

65

Table of Contents

periods). Additionally, for certain strategic suppliers, we have made, and may in the future be required to make, certain advance payments to secure the raw materials necessary for our module manufacturing.

We have also committed certain financial resources to fulfill our solar module collection and recycling obligations and have established a trust under which these funds are put into custodial accounts with an established and reputable bank. As of December 31, 2025, such funds were comprised of restricted marketable securities of $217.2 million and associated restricted cash and cash equivalents of $6.9 million. As of December 31, 2025, our module collection and recycling liability was $146.0 million. Trust funds may be disbursed for qualified module collection and recycling costs (including capital and facility related recycling costs), payments to customers for assuming collection and recycling obligations, and reimbursements of any overfunded amounts. Investments in the trust must meet certain investment quality criteria comparable to highly rated government or agency bonds. As necessary, we adjust the funded amounts for our estimated collection and recycling obligations based on the estimated costs of collecting and recycling covered modules, estimated rates of return on our restricted marketable securities, and an estimated solar module life of 25 years, less amounts already funded in prior years.

As of December 31, 2025, we had no off-balance sheet debt or similar obligations, other than financial assurance related instruments, which are not classified as debt. We do not guarantee any third-party debt. See Note 14. “Commitments and Contingencies” to our consolidated financial statements for further information about our financial assurance related instruments.

Operating Activities

The increase in net cash provided by operating activities during 2025 was primarily driven by higher cash receipts from module sales, including advance payments for future sales, higher proceeds from the sale of Section 45X tax credits, and higher receipts from factoring certain trade receivables, partially offset by higher payments made to suppliers.

Investing Activities

The decrease in net cash used in investing activities during 2025 was primarily due to lower purchases of property, plant and equipment for our manufacturing facilities in the United States and India and higher net proceeds from sales and maturities of marketable securities.

Financing Activities

The increase in net cash used in financing activities during 2025 was primarily due to repayment of debt, partially offset by new borrowings under various debt agreements.

Recent Accounting Pronouncements

In December 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2023-09, Income Taxes (Topic 740) - Improvements to Income Tax Disclosures, which requires greater disaggregation of an entity’s income tax disclosures. Among other things, ASU 2023-09 requires entities to disclose (i) specific categories in the effective tax rate reconciliation, (ii) pretax income or loss from continuing operations, separated between domestic and foreign jurisdictions, (iii) income tax expense or benefit from continuing operations, separated by federal, state, and foreign jurisdictions, and (iv) income taxes paid to federal, state, and foreign jurisdictions. We adopted ASU 2023-09 on a prospective basis effective January 1, 2025. The adoption did not have an impact on our consolidated financial position or results of operations but did require certain additional income tax disclosures. See Note 18. “Income Taxes” to our consolidated financial statements for the disclosures.

In November 2024, the FASB issued ASU 2024-03, Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses, which requires additional disclosure of specific types of expenses included in the expense captions presented on the face of the income statement. ASU 2024-03 is effective for public companies for annual reporting periods beginning after December 15, 2026 and interim reporting periods beginning after December 15, 2027. Early adoption is permitted, but we do not expect to do so. The disclosure requirements will be applied on a prospective basis, with the option to apply retrospectively. We are currently evaluating the impact ASU 2024-03 will have on our associated disclosures.

In December 2025, the FASB issued ASU 2025-10, Government Grants (Topic 832) - Accounting for Government Grants Received by Business Entities, to establish guidance on the recognition, measurement, and presentation of government grants received by business entities, which largely codifies our current approach to accounting for such grants. ASU 2025-10 is effective for public companies for annual reporting periods beginning after December 15, 2028 and interim reporting periods within those annual reporting periods. Early adoption is permitted, and we intend to adopt this standard in the first quarter of 2026. The guidance can be applied on a modified prospective basis, a modified retrospective basis, or a full retrospective basis, and we are currently evaluating these options. We do not expect ASU 2025-10 will have a significant impact on our consolidated financial statements or associated disclosures.

Critical Accounting Estimates

In preparing our consolidated financial statements in conformity with generally accepted accounting principles in the United States (“U.S. GAAP”), we make estimates and assumptions that affect the amounts of reported assets, liabilities, revenues, and expenses, as well as the disclosure of contingent liabilities. Some of our accounting policies require the application of significant judgment in the selection of the appropriate assumptions for making these estimates. By their nature, these judgments are subject to an inherent degree of uncertainty. We base our judgments and estimates on our historical experience, our forecasts, and other available information as appropriate. The actual results experienced by us may differ materially and adversely from our estimates. To the extent there are material differences between our estimates and the actual results, our future results of operations will be affected. Our significant accounting policies are described in Note 2. “Summary of Significant Accounting Policies” to our consolidated financial statements. The accounting policies that require the most significant judgment and estimates include the following:

Accrued Solar Module Collection and Recycling Liability. We previously established a module collection and recycling program, which has since been discontinued, to collect and recycle modules sold and covered under such program once the modules reach the end of their service lives. For legacy customer sales contracts that are covered under this program, we recognized expense at the time of sale based on the estimated cost to collect and recycle the covered solar modules. We estimate the cost of our obligations based on the present value of the expected future cost of collecting and recycling the solar modules, which includes estimates for the cost of packaging materials; the cost of freight from the solar module installation sites to a recycling center; material, labor, and capital costs; and by-product credits for certain materials recovered during the recycling process. We base these estimates on our

experience collecting and recycling solar modules and on certain assumptions regarding costs at the time the solar modules will be collected and recycled. In the periods between the time of sale and the related settlement of the collection and recycling obligation, we accrete the carrying amount of the associated liability and classify the corresponding expense within “Selling, general and administrative” expense on our consolidated statements of operations.

We periodically review our estimates of expected future recycling costs and may adjust our liability accordingly. Such adjustments are presented within “Cost of Sales” on our consolidated statements of operations. During the year ended December 31, 2025, we completed our annual cost study of obligations under our module collection and recycling program and determined that no adjustment to the associated liability was necessary. As of December 31, 2025, a 10% increase in the expected future recycling costs per module would increase the liability by $20.3 million.

Product Warranties. We provide a limited PV solar module warranty covering defects in materials and workmanship under normal use and service conditions for up to 12.5 years. We also typically warrant that modules installed in accordance with agreed-upon specifications will produce at least 98% of their labeled power output rating during the first year, with the warranty coverage reducing by a degradation factor every year thereafter throughout the limited power output warranty period of up to 30 years. Among other things, our solar module warranty also covers the resulting power output loss from cell cracking.

When we recognize revenue for sales of modules, we accrue liabilities for the estimated future costs of meeting our limited warranty obligations. We make and revise these estimates based primarily on the number of solar modules under warranty installed at customer locations, our historical experience with and projections of warranty claims, and our estimated per-module replacement costs. We also monitor our expected future module performance through certain quality and reliability testing and actual performance in certain field installation sites.

In general, we expect the return rates for our Series 6 and Series 7 modules to be lower than the rates of our older series. Accordingly, we estimate that the return rate for such newer series of module technology will be less than 1%. As of December 31, 2025, a 10 basis point increase in the return rates across all series of module technology would increase our product warranty liability by $24.3 million.

During the year ended December 31, 2024, we identified manufacturing issues affecting certain Series 7 modules manufactured in 2023 and 2024 that may cause the modules to experience premature power loss once installed in the field. As part of our monitoring of module performance through certain field installation sites, we tested over 100 Series 7 modules, which provided a preliminary view of potential levels of underperformance related to our initial production of Series 7 modules. We then estimated what subset of the entire population of Series 7 modules sold was affected by the manufacturing issues as not all Series 7 modules exhibited the variability in the production process that may lead to the identified underperformance. Accordingly, in arriving at the range of reasonably possible losses, we estimated that approximately two-thirds of Series 7 modules sold prior to December 31, 2024 may have been impacted, based on the Series 7 production schedule and the dates of when the underlying manufacturing issues were addressed at each affected facility.

During the year ended December 31, 2025, we settled certain of our obligations related to these issues and continued to engage in settlement discussions with various additional customers. We believe a reasonable estimate of potential future losses will range from approximately $35 million to $75 million. The low end of the range of reasonably possible losses reflects this settlement experience and considers performance data from select samples of Series 7 modules compared to warranted levels of performance, along with expectations of favorable Series 7 module energy performance attributes, such as a superior temperature coefficient and spectral response, that may partially offset underperformance from the identified issues. Such estimate of potential net underperformance was multiplied by the average selling price per watt of Series 7 modules to determine the low end of the expected costs to commercially settle warranty claims. The high end of the range of reasonably possible losses excludes any such favorable energy performance expectations from our advanced module technology and includes an estimate of incremental module underperformance beyond that exhibited in our samples of module performance data. Within that range, we recorded a specific warranty liability of $50 million as of December 31, 2025, which represents our best estimate of expected future losses related to the identified manufacturing issues; such liability was recorded as a reduction to revenue.

Government Grants. We continue to evaluate the extent of benefits available to us pursuant to the IRA, 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. For eligible components, the credit is equal to (i) $12 per square meter for a PV wafer, (ii) 4 cents multiplied by the capacity of a PV cell in watts, and (iii) 7 cents multiplied by the capacity of a PV module in watts. Based on the current form factor of our modules, we expect to qualify for a credit of approximately 17 cents per watt for each module produced in the United States and sold to a third party. During the year ended December 31, 2025, we recognized $1.6 billion of Section 45X credits as a reduction to “Cost of sales.”

For further information about certain key aspects of 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. If these financial benefits vary significantly from our assumptions, our business, financial condition, and results of operations could be adversely affected.” Any modifications to the law or its effects arising, for example, through (i) subsequent amendments to or interpretations of the law, and/or (ii) future laws or regulations rendering certain provisions of the IRA less effective or ineffective, in whole or in part, could result in material adverse changes to the benefits we have recognized and expect to recognize.

We recognize grants expected to be received directly from a government entity at their stated value. When we expect to transfer grants to a third party, we recognize the grants at, or adjust their carrying value to, the amount expected to be received from the transaction. Accordingly, changes in the expected realization of the grants could affect our results of operations. Additionally, the amount expected to be received from transfers to third parties may fluctuate based on market conditions or other factors that impact whether, and for how much, buyers are willing to purchase such credits.
