PART I

Company Overview

We are America’s leading photovoltaic (“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, thin film PV technology. Developed at research and development (“R&D”) labs in California and Ohio, the Company’s technology represents the next generation of solar power generation, providing 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. In addressing the overall global demand for electricity, PV solar modules provide energy at a lower levelized cost of electricity (“LCOE”), meaning the net present value of a system’s total life cycle costs divided by the quantity of energy that is expected to be produced over the system’s life, when compared to traditional forms of energy generation. With approximately $2 billion in cumulative R&D investments in the last 20 years, we have a demonstrated history of innovation and continuous improvement. We believe our strategies and points of differentiation provide the foundation for our competitive position and enable us to remain one of the preferred providers of PV solar modules.

Business Strategy

Advanced Module Technology

Our current module semiconductor structure is a single-junction polycrystalline thin film that uses Cadmium Telluride (“CdTe”) as the absorption layer. CdTe has absorption properties that are well matched to the solar spectrum and can deliver competitive wattage using approximately 2% to 3% of the amount of semiconductor material used to manufacture conventional crystalline silicon modules. In terms of performance, in many climates our solar modules provide certain energy production advantages relative to competing crystalline silicon modules. For example, our CdTe solar technology provides:

• a superior temperature coefficient, which results in stronger system performance in typical high insolation climates as the majority of a system’s generation, on average, occurs when module temperatures are well above 25°C (standard test conditions);

• a superior spectral response in humid environments where atmospheric moisture alters the solar spectrum relative to standard test conditions;

• a better partial shading response than competing crystalline silicon technologies, which may experience significantly lower energy generation than CdTe solar technologies when partial shading occurs; and

• an immunity to cell cracking and its resulting power output loss, a common failure often observed in crystalline silicon modules caused by poor manufacturing, handling, weather, or other conditions.

In addition to these technological advantages, we also 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. As a result of these and other factors, our solar modules can produce more annual energy in real-world operating conditions than conventional crystalline silicon modules with the same nameplate capacity.

Manufacturing Process and Distributed Manufacturing Presence

Our modules combine our leading-edge CdTe technology with the manufacturing excellence and quality control that comes from being the world’s most experienced producer of thin film PV solar modules. With more than 75 GW of modules sold worldwide, we have a demonstrated history of manufacturing success and innovation. Our global manufacturing footprint includes facilities in the United States, Malaysia, Vietnam, and India. During 2023, we commenced production of our Series 7TM (“Series 7”) modules at our third manufacturing facility in Ohio and our first manufacturing facility in India, which combine our thin film CdTe technology with a larger form factor and an innovative steel back rail mounting structure that reduces module installation time. During 2024, we commenced production of Series 7 modules at our first manufacturing facility in Alabama, bringing our total installed nameplate production capacity across all our facilities to approximately 21 GW. Additionally, we are in the process of expanding our manufacturing capacity by approximately 4 GW, including the construction of our fifth U.S. manufacturing facility, which is expected to commence operations in the second half of 2025.

Our modules are manufactured in a high-throughput, automated environment that integrates all manufacturing steps into a continuous flow process. This process eliminates the multiple supply chain operators and resource-intensive batch processing steps that are used to produce crystalline silicon modules, which typically occur over several days and across multiple factories. At the outset of our module production, a sheet of glass enters the production line and in a matter of hours is transformed into a completed module ready for shipment.

This proprietary production process includes the following three stages: (i) the deposition stage, (ii) the cell definition and treatment stage, and (iii) the assembly and test stage. In the deposition stage, panels of transparent oxide-coated glass are robotically loaded onto the production line where they are cleaned, laser-mark identified with a serial number, heated, and coated with thin layers of semiconductor material, including CdTe, using our vapor transport deposition technology, after which the semiconductor-coated plates are cooled rapidly to increase glass strength. In the cell definition and treatment stage, we use high-speed lasers to transform the large continuous semiconductor coating on the glass plate into a series of interconnected cells that deliver the desired current and voltage output. In this stage, we also treat the semiconductor film using certain chemistries and processes to improve the device’s performance and apply a back contact. In the assembly and test stage, we apply busbars, inter-layer material, and a rear glass cover sheet that is laminated to encapsulate the device. We then apply anti-reflective coating material to the substrate glass to further improve the module’s performance by increasing its ability to absorb sunlight. Finally, junction boxes, termination wires, and a frame are applied to complete the module assembly.

We maintain a robust quality and reliability assurance program that monitors critical process parameters and measures product performance to ensure that industry and more stringent internal standards are met. We also conduct acceptance testing for electrical leakage, visual quality, and power measurement on a solar simulator prior to preparing a module for shipment. Our quality and reliability tests complement production surveillance with an ongoing monitoring program, subjecting production modules to accelerated life stress testing to help ensure ongoing conformance to requirements of the International Electrotechnical Commission and Underwriters Laboratories Inc. These programs and tests help assure delivery of power and performance in the field with a high level of product quality and reliability.

An investment in our stock involves a high degree of risk. You should carefully consider the following information, together with the other information in this Annual Report on Form 10-K, before buying shares of our stock. If any of the following risks or uncertainties occur, our business, financial condition, and results of operations could be materially and adversely affected and the trading price of our stock could decline.

Summary of Risk Factors

The following is a summary of the principal risks and uncertainties that could materially adversely affect our business, financial condition, and results of operations and make an investment in our stock speculative or risky. You should read this summary together with the more detailed description of each risk factor contained below.

Risks Related to Our Markets and Customers

• Competition in solar markets globally and across the solar value chain is intense and could remain that way for an extended period of time. The solar industry may experience periods of structural imbalance between global PV module supply and demand that result in periods of pricing volatility. If our competitors reduce module pricing to levels near or below their manufacturing costs, or are able to operate at minimal or negative operating margins for sustained periods of time, or if global demand for PV modules decreases relative to installed production capacity, our business, financial condition, and results of operations could be adversely affected.

• The modification, reduction, elimination, or expiration of government subsidies, economic incentives, tax incentives, renewable energy targets, and other support for on-grid solar electricity applications, or other public policies could negatively impact demand and/or price levels for our solar modules. The imposition of tariffs on our products or their related raw materials and components could materially increase our costs to perform under our contracts with customers, which could adversely affect our results of operations.

• The loss of any of our large customers, or the inability of our customers and counterparties to perform under their contracts with us, could significantly reduce our net sales and negatively impact our results of operations.

Risks Related to Our Operations, Manufacturing, and Technology

• We face intense competition from manufacturers of crystalline silicon solar modules; if global supply exceeds global demand, it could lead to a further reduction in the average selling price for PV solar modules, which could reduce our net sales and adversely affect our results of operations.

• 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.

• Our failure to further refine our technology and develop and introduce improved PV products, including as a result of delays in implementing planned advancements, could render our solar modules uncompetitive and reduce our net sales, profitability, and/or market share.

• Several of our key raw materials and components, in particular CdTe, tellurium, products containing tellurium, and substrate glass, and manufacturing equipment are either single-sourced or sourced from a limited number of suppliers, and their failure to perform could cause manufacturing delays, especially as we expand or seek to expand our business, and/or impair our ability to deliver solar modules to customers in the required quality and quantities and at a price that is profitable to us.

Table of Contents

• Our failure to effectively manage module manufacturing production and selling costs, including costs related to raw materials and logistics services, could render our solar modules uncompetitive and reduce our net sales, profitability, and/or market share.

• 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.

• We may be unable to generate sufficient cash flows or have access to the sources of external financing necessary to fund planned capital investments in manufacturing capacity and product development.

Risks Related to Regulations

• 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.

• Existing regulations and policies, changes thereto, and new regulations and policies may present technical, regulatory, and economic barriers to the purchase and use of PV solar products, which may significantly reduce demand for our modules.

Risks Related to Our Markets and Customers

Competition in solar markets globally and across the solar value chain is intense and could remain that way for an extended period of time. The solar industry may experience periods of structural imbalance between global PV module supply and demand that result in periods of pricing volatility, which could have a material adverse effect on our business, financial condition, and results of operations.

In the aggregate, we believe manufacturers of solar cells and modules have significant installed production capacity, relative to global demand, and the ability for additional capacity expansion. For example, we estimate that in 2024 approximately 270 GW of capacity was added by solar module manufacturers, primarily in China. We believe the solar industry may from time to time experience periods of structural imbalance between supply and demand, and that excess capacity will continue to put pressure on pricing. 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. There may be additional pressure on global demand and average selling prices in the future resulting from fluctuating demand in certain major solar markets, such as China. If our competitors reduce module pricing to levels near or below their manufacturing costs, or are able to operate at minimal or negative operating margins for sustained periods of time, or if global demand for PV modules decreases relative to installed production capacity, our business, financial condition, and results of operations could be adversely affected.

The modification, reduction, elimination, or expiration of government subsidies, economic incentives, 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, 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.

Although we believe that solar energy will experience widespread adoption in those applications where it competes economically with traditional forms of energy without any incentive programs, in certain markets our net sales and profits remain subject to variability based on the availability and size of government subsidies and economic incentives. Federal, state, and local governmental bodies in many countries have provided subsidies in the form of

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, thin film PV technology. Developed at R&D labs in California and Ohio, the Company’s technology represents the next generation of solar power generation, providing 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 manufacturing facility in the United States and are in the process of expanding our manufacturing capacity, including the construction of our fifth manufacturing facility in the United States, which is expected to commence operations in the second half of 2025. With a global footprint that spans the United States, India, Malaysia, and Vietnam, we expect to have an annual manufacturing capacity of over 25 GW by 2026.

Certain of our financial results and other key operational developments for the year ended December 31, 2024 include the following:

• 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.

• Gross profit as a percentage of net sales increased 5.0 percentage points to 44.2% in 2024 from 39.2% in 2023. The increase was primarily driven by a higher sales mix of modules qualifying for the advanced manufacturing production credit under Section 45X of the IRC, termination payments associated with certain customer contract terminations in the U.S., India, and Europe, and an increase in the volume of modules sold to third parties, partially offset by higher module storage costs and a reduction in revenue related to manufacturing issues affecting certain Series 7 modules manufactured in 2023 and 2024.

• During 2024, we commenced production of Series 7 modules at our first manufacturing facility in Alabama, bringing our total installed nameplate production capacity across all our facilities to approximately 21 GW. During 2024, we produced 15.5 GW and sold 14.1 GW of solar modules. During 2025, we expect to produce between 18 GW and 19 GW and sell between 18 GW and 20 GW.

• In May 2024, we achieved a new world record CdTe research cell conversion efficiency of 23.1%, which was certified by the U.S. Department of Energy’s National Renewable Energy Laboratory.

• In July 2024, our dedicated R&D innovation center in Ohio was formally commissioned. This R&D facility features a high-volume manufacturing scale production pilot line, which is expected to enable the production of full-sized prototypes of thin film and tandem PV modules, supporting the implementation of our technology roadmap.

• In December 2024, we entered into two agreements with Visa Inc. (“Visa”) for the sale of $857.2 million of Section 45X tax credits we generated during 2024 for aggregate cash proceeds of $818.6 million and received initial cash proceeds of $616.0 million. We expect to receive the remaining cash proceeds during the first quarter of 2025.

Market Overview

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,

Foreign Currency Exchange Risk

Cash Flow Exposure. We expect certain of our subsidiaries to have future cash flows that will be denominated in currencies other than the subsidiaries’ functional currencies. Changes in the exchange rates between the functional currencies of our subsidiaries and the other currencies in which they transact will cause fluctuations in the cash flows we expect to receive or pay when these cash flows are realized or settled. Accordingly, from time to time we may enter into foreign exchange forward contracts to hedge a portion of these forecasted cash flows. These foreign exchange forward contracts qualify for accounting as cash flow hedges in accordance with Accounting Standards Codification (“ASC”) 815 and we designate them as such. We report unrealized gains or losses on such contracts in “Accumulated other comprehensive loss” and subsequently reclassify applicable amounts into earnings when the hedged transaction occurs and impacts earnings. For additional details on our derivative hedging instruments and activities, see Note 10. “Derivative Financial Instruments” to our consolidated financial statements.

Certain of our international operations, such as our manufacturing facilities in Malaysia and Vietnam, pay a portion of their operating expenses, including associate wages and utilities, in local currencies, which exposes us to foreign currency exchange risk for such expenses. Our manufacturing facilities are also exposed to foreign currency exchange risk for purchases of certain equipment and raw materials from international vendors. To the extent we expand into new markets, particularly emerging markets, our total foreign currency exchange risk, in terms of both size and exchange rate volatility, and the number of foreign currencies we are exposed to could increase significantly.

Transaction Exposure. Many of our subsidiaries have assets and liabilities (primarily cash, receivables, deferred taxes, payables, accrued expenses, lease liabilities, debt, and solar module collection and recycling liabilities) that are denominated in currencies other than the subsidiaries’ functional currencies. Changes in the exchange rates between the functional currencies of our subsidiaries and the other currencies in which these assets and liabilities are denominated will create fluctuations in our reported consolidated statements of operations. We may enter into foreign exchange forward contracts or other financial instruments to economically hedge assets and liabilities against the effects of currency exchange rate fluctuations. The gains and losses on such foreign exchange forward contracts will economically offset all or part of the transaction gains and losses that we recognize in earnings on the related foreign currency denominated assets and liabilities. For additional details on our economic hedging instruments and activities, see Note 10. “Derivative Financial Instruments” to our consolidated financial statements.

As of December 31, 2024, a 10% change in the U.S. dollar relative to our primary foreign currency exposures would have resulted in an $8.8 million change to our net foreign currency income or loss, including the effect of our hedging activities.

Interest Rate Risk

Variable Rate Debt Exposure. We are exposed to interest rate risk as certain of our debt arrangements have variable interest rates, exposing us to variability in interest expense and cash flows. See Note 13. “Debt” to our consolidated financial statements for additional information on our debt borrowing rates. An increase in relevant interest rates would increase the cost of borrowing under certain of our debt arrangements. For the year ended December 31, 2024, a 100 basis point change in such variable interest rates would not have had a significant impact to our interest expense.

Customer Financing Exposure. We are also indirectly exposed to interest rate risk because many of our customers depend on debt financings to purchase modules. An increase in interest rates could make it challenging for our customers to obtain the capital necessary to make such purchases on favorable terms, or at all. Such factors could reduce demand or lower the price we can charge for our modules, thereby reducing our net sales and gross profit.

Marketable Securities and Restricted Marketable Securities Exposure. We invest in various debt securities, which exposes us to interest rate risk. The primary objectives of our investment activities are to preserve principal and provide liquidity, while at the same time maximizing the return on our investments. Many of the securities in which we invest may be subject to market risk. Accordingly, a change in prevailing interest rates may cause the market value of such investments to fluctuate. For example, if we hold a security that was issued with an interest rate fixed at the then-prevailing rate and the prevailing interest rate subsequently rises, the market value of our investment may decline.

For the year ended December 31, 2024, our marketable securities earned a return of 5%, including the impact of fluctuations in the price of the underlying securities, and had a weighted-average maturity of 1 month as of the end of the period. Based on our investment positions as of December 31, 2024, a hypothetical 100 basis point change in interest rates would not have had a significant impact on the market value of our marketable securities investment portfolio. For the year ended December 31, 2024, our restricted marketable securities incurred a loss of less than 1%, including the impact of fluctuations in the price of the underlying securities, and had a weighted-average maturity of approximately 10 years as of the end of the period. Based on our restricted marketable securities positions as of December 31, 2024, a hypothetical 100 basis point change in interest rates would have resulted in a $15.4 million change in the market value of our restricted marketable securities portfolio.

Commodity and Component Risk

Some of our raw materials and components are sourced from a limited number of suppliers or a single supplier. Although we may enter into long-term supply contracts for certain raw materials and components, we may be exposed to price changes for certain raw materials and components used to manufacture our solar modules for which we are unable to secure long-term supply contracts or for which our demand exceeds our committed supply. From time to time, we may utilize derivative hedging instruments to mitigate such raw material price changes. In addition, the failure of a key supplier could disrupt our supply chain, which could result in higher prices and/or a disruption in our manufacturing process. As a result, we may be in default of our delivery obligations if we experience a manufacturing disruption. In addition to price changes in the raw materials and components used in our manufacturing process, we are also exposed to price changes associated with the shipping, handling, storage, and distribution of our modules. To mitigate such price changes, we have used, and expect to continue using, module contract structures that provide additional consideration to us if the cost of certain raw materials or logistics services exceeds a defined threshold. However, we may be unable to pass along the full amount of cost increases we experience for such raw materials, components, and logistics services to our customers.

Credit Risk

We have certain financial instruments that subject us to credit risk. These consist primarily of cash, cash equivalents, marketable securities, accounts receivable, restricted cash, restricted cash equivalents, restricted marketable securities, foreign exchange forward contracts, and commodity swap contracts. We are exposed to credit losses in the event of nonperformance by the counterparties to our financial instruments. We place these instruments with various high-quality financial institutions and limit the amount of credit risk from any one counterparty. We monitor the credit standing of our counterparty financial institutions. Our net sales are primarily concentrated among a limited number of customers. We monitor the financial condition of our customers and perform credit evaluations whenever considered necessary. We typically require some form of payment security from our customers, including, but not limited to, advance payments, parent guarantees, letters of credit, bank guarantees, or surety bonds.

Consolidated Financial Statements

Our consolidated financial statements as required by this item are included in Item 15. “Exhibits and Financial Statement Schedules.” See Item 15(a) for a list of our consolidated financial statements.

Evaluation of Disclosure Controls and Procedures

We carried out an evaluation, under the supervision and with the participation of management, including our Chief Executive Officer and Chief Financial Officer, of the effectiveness of our “disclosure controls and procedures” as defined in Exchange Act Rule 13a-15(e) and 15d-15(e). Based on that evaluation, our Chief Executive Officer and Chief Financial Officer concluded that as of December 31, 2024 our disclosure controls and procedures were effective to ensure that information required to be disclosed by us in reports that we file or submit under the Exchange Act is recorded, processed, summarized, and reported within the time periods specified in SEC rules and forms, and that such information is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure.

Management’s Report on Internal Control over Financial Reporting

Our management is responsible for establishing and maintaining adequate “internal control over financial reporting,” as defined in Exchange Act Rule 13a-15(f) and 15d-15(f). We also carried out an evaluation, under the supervision and with the participation of management, including our Chief Executive Officer and Chief Financial Officer, of the effectiveness of our internal control over financial reporting as of December 31, 2024 based on the criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (“COSO”). Our internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with U.S. GAAP. Based on such evaluation, our management concluded that our internal control over financial reporting was effective as of December 31, 2024. The effectiveness of our internal control over financial reporting as of December 31, 2024 has also been audited by PricewaterhouseCoopers LLP, an independent registered public accounting firm, as stated in its report, which appears herein.

Changes in Internal Control over Financial Reporting

We also carried out an evaluation, under the supervision and with the participation of management, including our Chief Executive Officer and Chief Financial Officer, of our “internal control over financial reporting” to determine whether any changes in our internal control over financial reporting occurred during the quarter ended December 31, 2024 that materially affected, or are reasonably likely to materially affect, our internal control over financial reporting. Based on that evaluation, there were no such changes in our internal control over financial reporting that occurred during the quarter ended December 31, 2024.

Limitations on the Effectiveness of Controls

Control systems, no matter how well designed and operated, can provide only reasonable, not absolute, assurance that the control systems’ objectives are being met. Further, the design of any system of controls must reflect the fact that there are resource constraints, and the benefits of all controls must be considered relative to their costs. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, within our company have been detected. These inherent limitations include the realities that judgments in decision-making can be faulty and that breakdowns can occur because of error or mistake. Control systems can also be circumvented by the individual acts of some persons, by collusion of two or more people, or by management override of the controls. The design of any system of controls is also based in part upon certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions. Over time, controls may become inadequate because of changes in conditions or deterioration in the degree of compliance with policies or procedures.

Insider Trading Arrangements

From time to time, our directors and officers may adopt plans for the purchase or sale of our securities. Such plans may be designed to satisfy the affirmative defense conditions of Rule 10b5-1 under the Exchange Act or may constitute non-Rule 10b5-1 trading arrangements (as defined in Item 408(c) of Regulation S-K). During the three months ended December 31, 2024, none of our officers or directors terminated Rule 10b5-1 trading arrangements or adopted or terminated non-Rule 10b5-1 trading arrangements. However, certain of our officers adopted Rule 10b5-1 trading plans for the sale of our securities. The following table provides certain terms of such plans:

Opinions on the Financial Statements and Internal Control over Financial Reporting

We have audited the accompanying consolidated balance sheets of First Solar, Inc. and its subsidiaries (the “Company”) as of December 31, 2024 and 2023, and the related consolidated statements of operations, of comprehensive income, of stockholders’ equity and of cash flows for each of the three years in the period ended December 31, 2024, including the related notes (collectively referred to as the “consolidated financial statements”). We also have audited the Company’s internal control over financial reporting as of December 31, 2024, based on criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO).

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of the Company as of December 31, 2024 and 2023, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2024 in conformity with accounting principles generally accepted in the United States of America. Also in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2024, based on criteria established in Internal Control – Integrated Framework (2013) issued by the COSO.

Basis for Opinions

The Company’s management is responsible for these consolidated financial statements, for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting, included in Management’s Report on Internal Control over Financial Reporting appearing under Item 9A. Our responsibility is to express opinions on the Company’s consolidated financial statements and on the Company’s internal control over financial reporting based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud, and whether effective internal control over financial reporting was maintained in all material respects.

Our audits of the consolidated financial statements included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.

Definition and Limitations of Internal Control over Financial Reporting

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Critical Audit Matters

The critical audit matter communicated below is a matter arising from the current period audit of the consolidated financial statements that was communicated or required to be communicated to the audit committee and that (i) relates to accounts or disclosures that are material to the consolidated financial statements and (ii) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates.

Revenue Recognition - Modules Segment

As described in Note 21 to the consolidated financial statements, the Company's modules segment net sales were $4.2 billion for the year ended December 31, 2024. As described in Note 15 to the consolidated financial statements, the Company recognizes 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 principal consideration for our determination that performing procedures relating to revenue recognition for the modules segment is a critical audit matter is a high degree of auditor effort in performing procedures related to the Company’s revenue recognition.
