**FIRST SOLAR, INC.**

**NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS**

**(Unaudited)**

**1. Basis of Presentation**

The accompanying unaudited condensed consolidated financial statements of First Solar, Inc. and its subsidiaries in this Quarterly Report have been prepared in accordance with generally accepted accounting principles in the United States of America ("U.S. GAAP") for interim financial information and pursuant to the instructions to Form 10-Q and Article 10 of Regulation S-X of the Securities and Exchange Commission (the "SEC"). Accordingly, these interim financial statements do not include all of the information and footnotes required by U.S. GAAP for annual financial statements. In the opinion of First Solar management, all adjustments (consisting only of normal recurring adjustments) considered necessary for a fair statement have been included. Certain prior period disclosures have been recast to conform to the current period presentation.

The preparation of condensed consolidated financial statements in conformity with U.S. GAAP requires us to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Despite our intention to establish accurate estimates and reasonable assumptions, actual results could differ materially from such estimates and assumptions. Operating results for the three and nine months ended September 30, 2025 are not necessarily indicative of the results that may be expected for the year ending December 31, 2025 or for any other period. The condensed consolidated balance sheet at December 31, 2024 has been derived from the audited consolidated financial statements at that date, but does not include all of the information and footnotes required by U.S. GAAP for complete financial statements. These interim financial statements and notes should be read in conjunction with the audited financial statements and notes thereto for the year ended December 31, 2024 included in our Annual Report on Form 10-K, which has been filed with the SEC.

Unless expressly stated or the context otherwise requires, the term "condensed consolidated financial statements" refers to the accompanying unaudited condensed consolidated financial statements contained in this Quarterly Report.

Our restricted marketable securities represent long-term investments to fund the estimated future cost of collecting and recycling modules covered under our solar module collection and recycling program. We have established a trust under which funds are put into custodial accounts with an established and reputable bank, for which First Solar, Inc.; First Solar Malaysia Sdn. Bhd.; and First Solar Manufacturing GmbH are grantors. As of September 30, 2025 and December 31, 2024, such custodial accounts also included noncurrent restricted cash and cash equivalents balances of $6.2 million and $5.0 million, respectively, which were reported within "Other assets." 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 fund any incremental amounts for our estimated collection and recycling obligations on an annual basis 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. During the nine months ended September 30, 2025 and September 30, 2024, we purchased $5.0 million and $7.9 million of restricted marketable securities, respectively, as part of our ongoing management of the custodial accounts.

See Note 8. "Fair Value Measurements" to our condensed consolidated financial statements for information about the fair value of our restricted marketable securities. The following tables summarize the unrealized gains and losses related to our restricted marketable securities, by major security type, as of September 30, 2025 and December 31, 2024 (in thousands):

As of September 30, 2025, the contractual maturities of these securities were between 5 years and 14 years, and restricted marketable securities with unrealized losses had generally been in a loss position for a period of time greater than 12 months. The unrealized losses were primarily due to increases in interest rates relative to rates at the time of purchase, and, based on the underlying credit quality of the investments, we expect to hold such securities until we recover our cost basis.

Accounts receivable trade, net consisted of the following at September 30, 2025 and December 31, 2024 (in thousands):

During 2024, we entered into various revolving factoring arrangements to sell certain trade receivables to unrelated financial institutions. Transfers under these arrangements, which retained servicing but were without recourse, qualified as true sales under Accounting Standards Codification ("ASC") 860, and we derecognized the sold receivables when control transferred to the financial institutions. We factored $245.7 million and $126.0 million under these arrangements and recorded $5.3 million and $1.9 million of discounts on factored receivables in "Selling, general and administrative" expense during the nine months ended September 30, 2025 and the year ended December 31, 2024, respectively. The trade receivables sold that remained outstanding as of September 30, 2025 and December 31, 2024 were $156.8 million and $126.0 million, respectively. Proceeds from the sale of receivables are classified as operating activities in our condensed consolidated statements of cash flows.

We evaluate our property, plant, and equipment for impairment under a held-and-used impairment model whenever events or changes in business circumstances arise that may indicate that the carrying amount of the assets may not be recoverable. Such events and changes include, among other things, significant changes in the manner of use of the assets, expectations that the assets may be sold or otherwise disposed of before the end of their useful lives, and the expected operational status of our international manufacturing facilities. As of September 30, 2025, the recoverability of our property, plant, and equipment was based on certain expectations regarding the ongoing operation of our international manufacturing facilities. However, it is reasonably possible that the operational status of one or more of our international facilities may be adversely affected by geopolitical developments, including trade policies or tariffs, which may result in future decisions to reduce, pause, or cease operations at these facilities. Such decisions may result in certain property, plant, and equipment being sold or otherwise disposed of before the end of their previously estimated useful lives, which, in turn, could result in a decrease in the value, and possible impairment, of this property, plant, and equipment. Accordingly, any such changes to the operational status of our international manufacturing facilities could be material to our condensed consolidated financial statements and have a significant adverse effect on our results of operations.

Depreciation of property, plant and equipment was $130.9 million and $375.3 million for the three and nine months ended September 30, 2025, respectively, and $107.1 million and $287.2 million for the three and nine months ended September 30, 2024, respectively.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2)During 2023, we entered into a power purchase agreement with Cleantech Solar ("Cleantech"), a leading provider of renewable energy solutions in India and Southeast Asia, and Cleantech committed to construct certain photovoltaic ("PV") solar and wind power-generating assets to supply electricity to our manufacturing facility in India.

During 2024, we purchased ownership interests in two subsidiaries of Cleantech for $7.9 million. These subsidiaries own certain of the power-generating assets that supply electricity to our facility, and we account for our investments in these subsidiaries using the equity method.

During the three and nine months ended September 30, 2025, we purchased $1.3 million and $2.5 million of electricity, respectively, from these subsidiaries. During the nine months ended September 30, 2024, we recognized $27.3 million of revenue from module sales to these subsidiaries.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1)During the nine months ended September 30, 2025, we transferred $492.8 million of trade receivables to a financial institution under a factoring arrangement with recourse, while retaining servicing responsibilities. Transfers under this arrangement do not meet the criteria for a sale of receivables and are therefore accounted for as secured borrowings.

As of September 30, 2025, transferred trade receivables of $194.4 million remained on our condensed consolidated balance sheets within "Accounts receivable trade, net," and a corresponding liability was recorded under "Other current liabilities." We record discounts on receivables factored with recourse as interest expense over the term of the respective receivables. Accordingly, during the three and nine months ended September 30, 2025, we recorded $4.7 million and $4.9 million, respectively, of interest expense associated with these arrangements.

**5. Government Grants**

Government grants represent benefits provided by federal, state, or local governments that are not subject to the scope of ASC 740. We recognize a grant when we have reasonable assurance that we will comply with the grant's conditions and that the grant will be received. Government grants whose primary condition is the purchase, construction, or acquisition of a long-lived asset are considered asset-based grants and are recognized as a reduction to such asset's cost basis, which reduces future depreciation. Other government grants not related to long-lived assets are considered income-based grants and are recognized as a reduction to the related cost of activities that generated the benefit.

The following table presents the benefits recognized from asset-based government grants, net of depreciation and amortization, in our condensed consolidated balance sheets as of September 30, 2025 and December 31, 2024 (in thousands):

In February 2021, the state government of Tamil Nadu, India granted First Solar certain incentives associated with the construction of our manufacturing facility in the state. Among other things, such incentives provide a 24% subsidy for eligible capital expenditures, contingent upon meeting certain minimum investment and employment commitments. We expect to receive the subsidy in six annual installments following the completion of the associated application and review process, which commenced earlier this year. Such incentives are reflected on our condensed consolidated balance sheets within "Government grants receivable, net" and "Government grants receivable," which classification reflects the expected timing of cash receipts.

In August 2022, the previous U.S. President signed into law the Inflation Reduction Act of 2022 ("IRA"). Among other things, the IRA offers a tax credit, pursuant to Section 45X of the Internal Revenue Code ("IRC"), for solar modules and solar module components manufactured in the United States and sold to third parties. Such credit may be refundable by the Internal Revenue Service ("IRS") or transferable to a third party and is available from 2023 to 2032, subject to phase down beginning in 2030. 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. We recognize such credit as a reduction to "Cost of sales" in the period the modules are sold to customers. Such credit is also reflected on our condensed consolidated balance sheets within "Government grants receivable, net" and "Government grants receivable," which classification reflects the expected timing of cash receipts.

In December 2024, we entered into two agreements for the sale of $857.2 million of Section 45X tax credits we generated during 2024 for aggregate cash proceeds of $818.6 million. We received initial cash proceeds of $616.0 million in December 2024 and received the remaining cash proceeds of $202.6 million in February 2025.

In June 2025, we entered into an agreement for the sale of $311.9 million of Section 45X tax credits we generated during 2025 for aggregate cash proceeds of $296.3 million. We received the full cash proceeds in June 2025.

In July 2025, we entered into an agreement for the sale of up to $391.0 million of Section 45X tax credits we expect to generate during 2025 for aggregate cash proceeds of up to $372.8 million. We received initial cash proceeds of $123.5 million and $124.2 million in July and October 2025, respectively, and we expect to receive the remaining cash proceeds in the fourth quarter of 2025.

**6. Derivative Financial Instruments**

As a global company, we are exposed in the normal course of business to various risks, including foreign currency and commodity price risks, that could affect our financial position, results of operations, and cash flows. We may use derivative instruments to hedge against these risks and do not hold such instruments for speculative or trading purposes.

Depending on the terms of the specific derivative instruments and market conditions, some of our derivative instruments may be assets and others liabilities at any particular balance sheet date. We report all of our derivative instruments at fair value and account for changes in the fair value of derivative instruments within "Accumulated other comprehensive loss" if the derivative instruments qualify for hedge accounting. For those derivative instruments that do not qualify for hedge accounting (i.e., "economic hedges"), we record the changes in fair value directly to earnings. See Note 8. "Fair Value Measurements" to our condensed consolidated financial statements for information about the techniques we use to measure the fair value of our derivative instruments.

***Foreign Currency Risk***

*Transaction Exposure and Economic Hedging*

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 condensed 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.

We also enter into foreign exchange forward contracts to economically hedge balance sheet and other exposures related to transactions between certain of our subsidiaries and transactions with third parties. Such contracts are considered economic hedges and do not qualify for hedge accounting. Accordingly, we recognize gains or losses from the fluctuations in foreign exchange rates and the fair value of these derivative contracts in "Foreign currency loss, net" on our condensed consolidated statements of operations.

As of September 30, 2025 and December 31, 2024, the U.S. Dollar equivalent notional values of our foreign exchange forward contracts that do not qualify for hedge accounting were $542.9 million and $603.4 million, respectively, including contracts in Indian Rupee, Euro, and Malaysian Ringgit, among other currencies.

***Commodity Price Risk***

From time to time, we use commodity swap contracts to mitigate our exposure to commodity price fluctuations for certain raw materials used in the production of our modules. During the year ended December 31, 2024, we entered into various commodity swap contracts to hedge a portion of our forecasted cash flows for purchases of steel between April 2024 and December 2024. Such swaps had an aggregate initial notional value based on short tons of forecasted steel purchases, equivalent to $7.6 million, and entitled us to receive the price based on the U.S. Midwest Hot-Rolled Coil Steel Index while requiring us to pay certain fixed prices. The notional amount of the commodity swap contracts proportionately adjusted with forecasted purchases of steel.

These commodity swap contracts qualified for accounting as cash flow hedges in accordance with ASC 815, and we designated them as such. We reported unrealized gains or losses on such contracts in "Accumulated other comprehensive loss" and subsequently reclassified applicable amounts into earnings when the hedged transactions occurred and impacted earnings. We determined that these derivative financial instruments were highly effective as cash flow hedges as of December 31, 2024. As of September 30, 2025, we had no outstanding cash flow hedges.

**8. Fair Value Measurements**

The following is a description of the valuation techniques that we use to measure the fair value of assets and liabilities that we measure and report at fair value on a recurring basis:

*• Cash Equivalents and Restricted Cash Equivalents.* At September 30, 2025 and December 31, 2024, our cash equivalents and restricted cash equivalents consisted of money market funds. We value our cash equivalents and restricted cash equivalents using observable inputs that reflect quoted prices for securities with identical characteristics and classify the valuation techniques that use these inputs as Level 1.

*• Marketable Securities and Restricted Marketable Securities.* At September 30, 2025 and December 31, 2024, our marketable securities consisted of time deposits and U.S. debt, and our restricted marketable securities consisted of U.S. debt, foreign and U.S. government obligations, and supranational debt. We value our marketable securities and restricted marketable securities using observable inputs that reflect quoted prices for securities with identical characteristics or quoted prices for securities with similar characteristics and other observable inputs (such as interest rates that are observable at commonly quoted intervals). Accordingly, we classify the valuation techniques that use these inputs as either Level 1 or Level 2 depending on the inputs used. We also consider the effect of our counterparties' credit standing in these fair value measurements.

*• Derivative Assets and Liabilities*. At September 30, 2025 and December 31, 2024, our derivative assets and liabilities consisted of foreign exchange forward contracts involving major currencies and commodity swap contracts involving major commodity prices. Since our derivative assets and liabilities are not traded on an exchange, we value them using standard industry valuation models. As applicable, these models project future cash flows and discount the amounts to a present value using market-based observable inputs, including credit risk, foreign exchange rates, forward and spot prices for currencies, and forward prices for commodities. These inputs are observable in active markets over the contract term of the derivative instruments we hold, and accordingly, we classify the valuation techniques as Level 2. In evaluating credit risk, we consider the effect of our counterparties' and our own credit standing in the fair value measurements of our derivative assets and liabilities, respectively.

• *Contingent Consideration.* At September 30, 2025 and December 31, 2024, our contingent consideration consisted of balances associated with a prior business acquisition. We project future cash outflows associated with certain payout outcomes and discount the amounts to a present value using significant unobservable inputs, including various probabilities and assumptions regarding the timing, nature, and extent of technical milestones achieved. We classify the valuation technique that uses these inputs as Level 3.

The carrying values in our condensed consolidated balance sheets of our trade accounts receivable, restricted cash, current government grants receivable, accounts payable, accrued expenses, and debt arrangements with an original maturity of less than one year approximated their fair values due to their nature and relatively short maturities; therefore, we excluded them from the foregoing table. The fair value measurements for our noncurrent government grants receivable and long-term debt are considered Level 2 measurements under the fair value hierarchy.

***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.

***Revolving Credit Facility***

In June 2023, we entered into a credit agreement with several financial institutions as lenders and JPMorgan Chase Bank, N.A. as administrative agent, which provides us with a senior secured credit facility (the "Revolving Credit Facility") with an aggregate borrowing capacity of $1.0 billion. Borrowing under the Revolving Credit Facility bears interest at a rate per annum equal to, at our option, (i) the Term Secured Overnight Financing Rate ("Term SOFR"), plus a credit spread of 0.10%, plus a margin that ranges from 1.25% to 2.25% or (ii) an alternate base rate as defined in the credit agreement, plus a margin that ranges from 0.25% to 1.25%. The margins under the Revolving Credit Facility are based on our net leverage ratio or, if we elect to switch to a credit ratings-based system after the investment grade ratings trigger date occurs (as defined in the credit agreement), on our public debt rating.

In addition to paying interest on outstanding principal under the Revolving Credit Facility, we are required to pay an unused commitment fee that ranges from 0.125% to 0.375% per annum based on the same factors discussed above and the daily unused commitments under the facility. We are also required to pay (i) a letter of credit fee based on the applicable margin for Term SOFR loans on the face amount of each letter of credit, (ii) a letter of credit fronting fee as agreed by us and such issuing lender, and (iii) other customary letter of credit fees. Our Revolving Credit Facility matures in June 2028. Loans and letters of credit issued under the Revolving Credit Facility are secured by liens on substantially all of our tangible and intangible assets.

As of September 30, 2025 and December 31, 2024, we had no outstanding debt or letters of credit under our Revolving Credit Facility.

***India Credit Facility***

In July 2022, FS India Solar Ventures Private Limited ("FSISV"), our indirect wholly-owned subsidiary, entered into a finance agreement (the "India Credit Facility") with the U.S. International Development Finance Corporation for aggregate borrowing of up to $500.0 million for the development and construction of a solar module manufacturing facility in India. Principal on the India Credit Facility is payable in scheduled semi-annual installments beginning in August 2024 through the facility's expected maturity in August 2029. The India Credit Facility is guaranteed by First Solar, Inc.

***India Credit Agricole Working Capital Facility***

In August 2022, FSISV entered into a working capital facility agreement (the "India Credit Agricole Working Capital Facility") with Credit Agricole Corporate and Investment Bank, for the issuance of letters of credit, bank guarantees, and overdrafts. In 2024, the India Credit Agricole Working Capital Facility was amended to include certain working capital loans, and during 2025, the facility limit was increased to INR 8.5 billion ($95.9 million). The outstanding balance matures in the fourth quarter of 2025. The India Credit Agricole Working Capital Facility is guaranteed by First Solar, Inc.

***India JPM Working Capital Facility***

In December 2022, FSISV entered into a working capital facility agreement (the "India JPM Working Capital Facility") with JPMorgan Chase Bank, N.A. for the issuance of bank guarantees, bonds, and other similar forms of security. During 2023, the India JPM Working Capital Facility was amended to include certain working capital loans of up to INR 6.2 billion ($70.2 million). The outstanding balance matures in the fourth quarter of 2025 and the second quarter of 2026. The India JPM Working Capital Facility is guaranteed by First Solar, Inc.

***India HSBC Working Capital Facility***

In February 2024, FSISV entered into a working capital facility agreement (the "India HSBC Working Capital Facility") with the Hongkong and Shanghai Banking Corporation Limited, which provides certain working capital loans of up to INR 8.2 billion ($92.5 million). The outstanding balance matures in the fourth quarter of 2025 and the first quarter of 2026. The India HSBC Working Capital Facility is guaranteed by First Solar, Inc.

***India Citibank Working Capital Facility***

In August 2024, FSISV entered into a working capital facility agreement (the "India Citibank Working Capital Facility") with Citibank, N.A. In January 2025, the India Citibank Working Capital Facility was amended to provide certain working capital loans of up to INR 6.4 billion ($72.2 million). The outstanding balance matures in the fourth quarter of 2025. The India Citibank Working Capital Facility is guaranteed by First Solar, Inc.

**10. Commitments and Contingencies**

***Commercial Commitments***

During the normal course of business, we enter into commercial commitments in the form of letters of credit and surety bonds to provide financial and performance assurance to third parties. As of September 30, 2025, the issued and outstanding amounts and available capacities under these commitments were as follows (in millions):

---

| | | |
|:---|:---|:---|
| | **Issued and Outstanding** | **Available Capacity** |
| Revolving Credit Facility (1) | $— | $250.0 |
| Bilateral facilities (2) | 235.4 | 123.9 |
| Surety bonds | 130.5 | 137.3 |

---

——————————

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1)Our Revolving Credit Facility provides us with a sub-limit of $250.0 million to issue letters of credit, at a fee based on the applicable margin for Term SOFR loans, a fronting fee, and other customary letter of credit fees.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2)Of the total letters of credit issued under the bilateral facilities, $1.6 million was secured with cash.

***Product Warranties***

When we recognize revenue for sales of modules, we accrue liabilities for the estimated future costs of meeting our limited warranty obligations. We estimate our limited product warranty liability for power output and defects in materials and workmanship under normal use and service conditions based on return rates for each series of module technology and other factors. 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. From time to time, we have taken remediation actions with respect to affected modules beyond our limited warranties and may elect to do so in the future, in which case we would incur additional costs. Such potential voluntary future remediation actions beyond our limited warranty obligations may be material to our condensed consolidated statements of operations if we commit to any such remediation actions.

<u>[**Table of Contents**](#iacbb247b2553403b9d641c6defc6042c_7)</u>

Product warranty activities during the three and nine months ended September 30, 2025 and 2024 were as follows (in thousands):

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. Subsequently, we identified the causes of these issues and compiled and evaluated data on the expected impact such issues may have on performance, including collecting samples of module performance data from several locations. During the nine months ended September 30, 2025, we settled certain of our obligations related to these issues and continued to engage in settlement discussions with various additional customers. Based on such settlement experience, the estimated number of affected modules, and projections of probable costs to remediate the issues, we believe a reasonable estimate of potential future losses will range from approximately $50 million to $90 million. Within that range, we recorded a specific warranty liability of $65 million as of September 30, 2025, which represents our best estimate of expected future losses related to the identified manufacturing issues. The ultimate loss we will incur will depend on the extent of the premature power loss that is experienced in relation to the obligations under our limited product warranties, as well as any potential additional commitments we may make to remediate the affected modules. As additional information becomes available to us, our estimate of the aggregate losses related to these manufacturing issues may change, and any change in estimate may also result in a change to our product warranty liability.

***Indemnifications***

In certain limited circumstances, we have provided indemnifications to customers or other parties under which we are contractually obligated to compensate such parties for losses they suffer resulting from a breach of a representation, warranty, or covenant; the resolution of specific matters associated with a solar project's development or construction; guarantees of a third party's payment or performance obligations; or any disallowance or lack of the right to claim all or any portion of certain tax credits. For contracts that have such indemnification provisions, we initially recognize a liability under ASC 460 for the estimated premium that would be required by a guarantor to issue the same indemnity in a standalone arm's-length transaction with an unrelated party. We may base these estimates on the cost of insurance or other instruments that cover the underlying risks being indemnified and may purchase such instruments to mitigate our exposure to potential indemnification payments. We subsequently measure such liabilities at the greater of the initially estimated premium or the contingent liability required to be recognized under ASC 450. We recognize any indemnification liabilities as a reduction of earnings associated with the related transaction.

After an indemnification liability is recorded, we derecognize such amount pursuant to ASC 460 depending on the nature of the indemnity, which derecognition typically occurs upon expiration or settlement of the arrangement, and any contingent aspects of the indemnity are accounted for in accordance with ASC 450. As of December 31, 2024, we accrued $2.5 million of indemnification liabilities. As of September 30, 2025, we had no accrual for indemnification liabilities. Our potential future payments under these indemnifications primarily relate to legislative changes that may adversely affect an entity's ability to benefit from previously transferred Section 45X tax credits.

***Contingent Consideration***

As part of a business acquisition in May 2023, we agreed to pay additional consideration of up to $42.5 million to the selling shareholders contingent upon the successful achievement of certain technical milestones. During the nine months ended September 30, 2025, we reduced the associated long-term contingent consideration liability to $3.6 million, based on certain revisions to the probability and timing of achieving the remaining milestones. Changes in the fair value of the contingent consideration arrangement are classified within "Research and development" expense in our condensed consolidated statements of operations. As of December 31, 2024, we recorded $6.5 million of long-term liabilities for such contingent obligation, which was based on its estimated fair value at that time.

***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 agreed to pay the costs for the collection and recycling of qualifying solar modules, and the end-users agreed to notify us, disassemble their solar power systems, package the solar modules for shipment, and revert ownership rights over the modules back to us at the end of the modules' service lives. Accordingly, we recorded any collection and recycling obligations within "Cost of sales" at the time of sale based on the estimated cost to collect and recycle the covered solar modules.

We estimate the cost of our collection and recycling 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 condensed consolidated statements of operations.

Our module collection and recycling liability was $145.1 million and $134.4 million as of September 30, 2025 and December 31, 2024, respectively. See Note 3. "Restricted Marketable Securities" to our condensed consolidated financial statements for more information about our arrangements for funding this liability.

***Legal Proceedings***

During the year ended December 31, 2022, we received several indemnification demands from certain customers, for whom we provided EPC services, regarding claims that such customers' PV tracker systems infringe, in part, on patents owned by Rovshan Sade ("Plaintiff"), the owner of a company called Trabant Solar, Inc. In January 2023, we were notified by two of our customers that Plaintiff served them with patent infringement complaints, and we have assumed the defense of these claims. We have conducted due diligence on the patents and claims and believe that we will prevail in the actions. After a series of stays of the proceedings, the last of which was lifted on July 14, 2025, the parties have begun responding to their respective discovery demands. Each party has submitted its claim construction filings with the court, and a claim construction hearing is not anticipated before early 2026. At this time, we are not in a position to assess the likelihood of any potential loss or adverse effect on our financial condition or to estimate the amount or range of possible loss, if any, from these actions.

<u>[**Table of Contents**](#iacbb247b2553403b9d641c6defc6042c_7)</u>

In April 2019, a subcontractor of First Solar sustained certain injuries while performing work at a former project site and, in May 2019, commenced legal action against a subsidiary of the Company. In June 2023, a jury awarded damages of approximately $51.3 million to the plaintiff. On September 21, 2023, the Superior Court of California for Monterey County ruled, in response to a motion for remittitur filed by the Company, that the damages awarded to the plaintiff were excessive and reduced the award from $51.3 million to $21.8 million. The plaintiff and defendant have appealed and cross appealed varying aspects of the verdict and the remittitur. Accordingly, due to the uncertainty surrounding the multiple decisions and appeals, as of September 30, 2025, we recorded a $21.8 million accrued litigation payable included in "Other current liabilities" in our condensed consolidated balance sheet. We believe the full amount of awarded damages will be covered by our various insurance policies. Accordingly, we also recorded a $21.8 million receivable included in "Other current assets" in our condensed consolidated balance sheet as of September 30, 2025. The plaintiff did not accept the reduced award by the court ordered deadline of October 10, 2023. As a result, the $21.8 million award has been vacated, and a new trial is expected to be scheduled. We, in conjunction with our insurance carriers, are challenging the initial verdict in an appellate court, and the plaintiff is cross appealing from the decision to reduce the award, among other issues, stemming from the trial. We filed our initial briefs with the court on December 20, 2024. The plaintiff submitted its briefs on April 23, 2025. We filed our reply briefings on August 6, 2025.

On September 29, 2023 and June 5, 2024, the Company received subpoenas from the Division of Enforcement of the SEC seeking documents and information relating to the Company's operations in India, the Company's entry into a PV module supply agreement with an India-based customer, and certain aspects of the Company's technology roadmap, among other things. On May 7, 2025, we received a notice from the SEC stating that the SEC had concluded its investigation as to First Solar and noting that based on the information collected to date, the SEC staff did not intend to recommend an enforcement action against First Solar.

We are party to other legal matters and claims in the normal course of our operations. While we believe the ultimate outcome of these matters and claims will not have a material adverse effect on our financial position, results of operations, or cash flows, the outcome of such matters and claims is not determinable with certainty, and negative outcomes may adversely affect us.

**11. Revenue from Contracts with Customers**

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. Our customer contracts generally contain provisions that (i) require us to pay the customer liquidated damages if we fail to deliver modules by scheduled dates or if we fail to deliver modules that meet certain U.S. domestic content requirements and (ii) entitle us to a termination payment if the customer defaults on its contractual obligations and the contract is terminated. For sales of modules imported into the United States, our customer contracts generally include provisions that are intended to mitigate the adverse impact from changes in trade policy, such as tariffs. If a contract is terminated on the basis of these trade policy provisions, such contract would effectively be canceled without liability to either party, resulting in a corresponding reduction in future sales of solar modules related to such contract and the return of any customer deposit under the contract, if applicable.

The following table reflects the changes in our contract liabilities, which we classify as "Deferred revenue," for the nine months ended September 30, 2025 (in thousands):

---

| | | | | |
|:---|:---|:---|:---|:---|
| | **September 30,<br>2025** | **December 31,<br>2024** | **Nine Month Change** | **Nine Month Change** |
| Deferred revenue | $2217765 | $2039825 | $177940 | 9% |

---

------

<u>[**Table of Contents**](#iacbb247b2553403b9d641c6defc6042c_7)</u>

During the nine months ended September 30, 2025, our contract liabilities increased by $177.9 million primarily due to (i) advance payments received in the current period for future sales of solar modules, partially offset by (ii) the recognition of revenue for sales of solar modules for which payment was received in prior years, (iii) the recognition of revenue of $121 million associated with certain customer contract terminations, (iv) the reversal of a $63 million advance payment previously accrued due to our deferral of a customer's invoice due date, and (v) the restructuring of payment terms with a customer that resulted in the return of $50 million of previously received advance payments in exchange for a letter or credit. During the nine months ended September 30, 2025 and 2024, we recognized revenue of $309.5 million and $284.0 million, respectively, that was included in the corresponding contract liability balance at the beginning of the periods.

During the three months ended September 30, 2025, we terminated various master supply agreements with a major oil and gas customer due to the customer's failure to cure several breaches of its contractual obligations. These terminations triggered certain contractual termination payment provisions, of which we recognized $61.0 million as revenue for the advance payments previously received from the customer. These terminations reduced our contracted backlog of solar modules by 6.6 GW at an aggregate transaction price of $1.9 billion.

As of September 30, 2025, we had entered into contracts with customers for the future sale of 53.7 GW of solar modules for an aggregate transaction price of $16.4 billion, which we expect to recognize as revenue through 2030 as we transfer control of the modules to the customers. This volume and transaction price exclude contracts with customers in India for which payment has not been fully secured. This transaction price also excludes estimates of variable consideration associated with (i) future module technology improvements, including enhancements to certain energy related attributes, (ii) sales freight in excess of defined thresholds, (iii) changes to certain commodity prices, (iv) the module wattage committed for delivery, (v) the volume of modules sold that meet certain U.S. domestic content requirements, and (vi) 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. These contracts may also be subject to amendments as agreed to by the parties to the contract. These amendments may increase or decrease the volume of modules to be sold under the contract, change delivery schedules, or otherwise adjust the expected revenue under these contracts.

**12. Share-Based Compensation**

The following table presents share-based compensation expense recognized in our condensed consolidated statements of operations for the three and nine months ended September 30, 2025 and 2024 (in thousands):

---

| | | | | |

| | **Three Months Ended <br>September 30,** | **Three Months Ended <br>September 30,** | **Nine Months Ended <br>September 30,** | **Nine Months Ended <br>September 30,** |
| | **2025** | **2024** | **2025** | **2024** |
| Cost of sales | $835 | $505 | $2141 | $2920 |
| Selling, general and administrative | 5400 | 5610 | 12100 | 16484 |

| &nbsp;&nbsp;&nbsp;&nbsp;Total share-based compensation expense | $7319 | $6796 | $16713 | $21987 |

---

As of September 30, 2025, we had $28.3 million of unrecognized share-based compensation expense related to unvested restricted stock and performance units, which we expect to recognize over a weighted-average period of approximately 1.3 years.

------

<u>[**Table of Contents**](#iacbb247b2553403b9d641c6defc6042c_7)</u>

In May 2021 and March 2022, the compensation committee of our board of directors approved grants of performance units for key executive officers to be earned over multi-year performance periods, which ended in December 2023 and December 2024, respectively. Vesting of the 2021 and 2022 grants of performance units was contingent upon the specific attainment targets of each grant, which targets included metrics such as contracted revenue, return on capital, cost per watt, incremental average selling price, and operating income metrics. In February 2024, the compensation committee certified the achievement of the vesting conditions applicable to the 2021 grants, which approximated the maximum level of performance. In February 2025, the compensation committee certified the achievement of the vesting conditions applicable to the 2022 grants, which approximated the maximum level of performance. Accordingly, each participant received one share of common stock for each vested performance unit granted, net of any tax withholdings.

In March 2023, March 2024, and May 2025, the compensation committee approved additional grants of performance units for key executive officers; such grants are expected to be earned over a multi-year performance period ending in December 2025, December 2026, and December 2027, respectively. Vesting of the 2023, 2024, and 2025 grants of performance units is contingent upon the specific attainment targets of each grant, which targets include metrics such as contracted revenue, production, incremental average selling price, operating margin, and technology development.

Vesting of performance units is also contingent upon the employment of program participants through the applicable vesting dates, with limited exceptions in case of death, disability, a qualifying retirement, or a change-in-control of First Solar. Outstanding performance units are included in the computation of diluted net income per share based on the number of shares that would be issuable if the end of the reporting period were the end of the contingency period.

**13. Income Taxes**

In July 2025, the U.S. President signed the budget reconciliation legislation (House of Representatives 1, or "H.R.1") into law, commonly referred to as the "One Big Beautiful Bill." H.R.1 includes significant provisions, such as (i) the permanent extension of certain expiring provisions of the Tax Cuts and Jobs Act, (ii) modifications to the international tax framework, and (iii) the restoration of favorable tax treatment for certain business provisions. H.R.1 has multiple effective dates, with certain provisions effective in 2025 and others implemented through 2027. The enactment of H.R.1 did not result in a material impact to our condensed consolidated financial statements.

In August 2022, the previous U.S. President signed into law the IRA, which revised U.S. tax law by, among other things, including a new corporate alternative minimum tax of 15% on certain large corporations, imposing a 1% excise tax on stock buybacks, and providing various incentives, including the introduction of the advanced manufacturing production credit under Section 45X of the IRC. The provisions of the IRA are generally effective for tax years beginning after 2022.

Our effective tax rate was 2.2% and 6.4% for the nine months ended September 30, 2025 and 2024, respectively. The decrease in our effective tax rate was primarily driven by the relative amounts of advanced manufacturing production credits earned in each period, partially offset by lower relative amounts of income earned in foreign jurisdictions with lower tax rates. Our provision for income taxes differed from the amount computed by applying the U.S. statutory federal income tax rate of 21% primarily due to the effect of tax law associated with the IRA.

Our Malaysian subsidiary has been granted a long-term tax holiday that expires in 2027. The tax holiday, which generally provides for a full exemption from Malaysian income tax, is conditional upon our continued compliance with certain employment and investment thresholds. We are currently in compliance with such thresholds.

------

<u>[**Table of Contents**](#iacbb247b2553403b9d641c6defc6042c_7)</u>

Our Vietnamese subsidiary has been granted a long-term tax incentive that generally provides a full exemption from Vietnamese income tax through 2023, followed by reduced tax rates of 5% through 2032 and 10% through 2036. Such long-term tax incentive is conditional upon our continued compliance with certain revenue and research and development ("R&D") spending thresholds. We are currently in compliance with such thresholds.

We are subject to audit by federal, state, local, and foreign tax authorities. We are currently under examination in India, Chile, the United States, and the States of Tennessee and Texas. We believe that adequate provisions have been made for any adjustments that may result from tax examinations. However, the outcome of tax examinations cannot be predicted with certainty. If any issues addressed by our tax examinations are not resolved in a manner consistent with our expectations, we could be required to adjust our provision for income taxes in the period such resolution occurs.

**14. Net Income per Share**

**16. Segment Reporting**

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. Third-party customers of this segment include system developers, independent power producers, utilities, commercial and industrial companies, and other system owners and operators. Our business is managed by our Chief Executive Officer, who is also considered our chief operating decision maker ("CODM").

Prior to 2025, we regularly provided our CODM with financial information that included certain legacy business activities. As such activities have continued to decline in size and importance, our CODM no longer receives detailed financial information at this disaggregated level. Therefore, we currently operate as a single operating segment, and our disclosures reflect this change.

Although our CODM regularly uses gross profit for key operating decisions about allocating resources and assessing performance, we have concluded that consolidated net income is also used and is the measure of profit or loss required to be disclosed under the provisions of ASC 280 for our single operating segment. Accordingly, we considered whether there were any significant expense categories to disclose and concluded that the condensed consolidated financial statements and accompanying notes thereto include the relevant categories regularly provided to our CODM. The measure of segment assets is reported in our condensed consolidated balance sheets as "Total assets."

**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, our 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 and fifth manufacturing facilities in the United States and completed the expansion of our manufacturing footprint at our existing facilities in Ohio. Our global footprint spans the United States, India, Malaysia, and Vietnam.

Certain of our financial results and other key operational developments for the three months ended September 30, 2025 include the following:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Net sales for the three months ended September 30, 2025 increased by 79.7% to $1.6 billion compared to $0.9 billion for the same period in 2024. The increase was primarily due to a 79.1% increase in the volume of modules sold to third parties and the prior period reduction in revenue related to manufacturing issues affecting certain Series 7 modules manufactured in 2023 and 2024.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• During the three months ended September 30, 2025, we terminated various master supply agreements with a major oil and gas customer due to the customer's failure to cure several breaches of its 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 the 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 the customer for the remaining termination payments along with certain other receivables for solar modules previously delivered to the customer.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;*•* Gross profit as a percentage of net sales for the three months ended September 30, 2025 decreased 11.9 percentage points to 38.3% from 50.2% for the same period in 2024. The decrease was primarily due to higher logistics, detention, and demurrage charges; a lower sales mix of modules qualifying for the advanced manufacturing production credit under Section 45X of the IRC; and, as a percentage of net sales, lower relative revenue associated with certain customer contract terminations; partially offset by the prior period reduction in revenue related to manufacturing issues affecting certain Series 7 modules manufactured in 2023 and 2024.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• During the three months ended September 30, 2025, we commenced production of Series 7 modules at our new manufacturing facility in Louisiana, bringing our total installed nameplate production capacity across all our facilities to approximately 23.5 GW. During the three months ended September 30, 2025, we produced 3.6 GW and sold 5.3 GW of solar modules.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• In July 2025, we entered into an agreement for the sale of up to $391.0 million of Section 45X tax credits we expect to generate during 2025 for aggregate cash proceeds of up to $372.8 million. We received initial cash proceeds of $123.5 million and $124.2 million in July and October 2025, respectively, and we expect to receive the remaining cash proceeds in the fourth quarter of 2025.

**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 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 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. 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 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. Notwithstanding these considerations, utility and corporate demand for energy and overall electric load growth, especially as a result of artificial intelligence-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.

Internationally, 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 policies that provide a level playing field for domestic manufacturers of solar cells and modules. We also continue to focus on our strategies and points of differentiation, which include our advanced module technology, our manufacturing process and distributed manufacturing presence, our 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 relatively stable due, in part, to the rising demand for domestically manufactured modules as a result of the IRA 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 research and development of a viable and commercially scalable perovskite product.

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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *CuRe*. Our CuRe program is intended to improve our current semiconductor structure by replacing copper with certain other elements that are expected to enhance module performance by improving its bifaciality characteristics, improving its temperature coefficient, and improving its warranted degradation. As a result of these performance improvements, our PV solar modules are expected to produce more energy in real world operating conditions over their estimated useful lives than crystalline silicon modules with the same nameplate capacity. In 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 early 2026, we intend to initiate a phased replication of the technology across certain manufacturing facilities within our fleet.

<u>[**Table of Contents**](#iacbb247b2553403b9d641c6defc6042c_7)</u>

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;*• 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 viable and 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 capacity. 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 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.

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 further 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 Part II. "Other Information" Item 1A. "Risk Factors" for discussion of other risks (the "Risk Factors") 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.

<u>[**Table of Contents**](#iacbb247b2553403b9d641c6defc6042c_7)</u>

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:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *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 Investment Tax Credit ("ITC") and Production Tax Credit ("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 foreign entity of concern ("FEOC"). H.R.1 also severely limits Section 45X tax credit eligibility for products manufactured by, or with material assistance from, a FEOC.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *India*. In March 2023, the government of India allocated financial incentives under the Production Linked Incentive ("PLI") scheme to certain PV module manufacturers, including First Solar. The PLI scheme is expected to provide aggregate funding of INR 185 billion ($2.1 billion) to certain PV module manufacturers, of which INR 11.8 billion ($133 million) was allocated to First Solar, to promote the manufacturing of high efficiency solar modules in India and to reduce India's dependency on foreign imports of solar modules. Under the PLI scheme, manufacturers were selected through a competitive bid process and may be entitled to receive certain cash incentives over a five-year period following the commissioning of their manufacturing facilities. Among other things, such incentives are subject to attaining certain minimum thresholds for module efficiency and temperature coefficient and require that a certain proportion of raw materials be sourced from the domestic market. Such conditions will be evaluated on a quarterly basis from 2026 through 2031. At this time, it is uncertain to what extent we may qualify for such incentives.

------

<u>[**Table of Contents**](#iacbb247b2553403b9d641c6defc6042c_7)</u>

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:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *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 was extended for an additional 90 days on August 12, 2025. On July 2, 2025, the U.S. President announced that the United States and Vietnam had reached a preliminary trade agreement, which placed a 20% tariff on all products of Vietnam and a 40% tariff on all "transshipped" goods. On July 31, 2025, the U.S. President issued an executive order detailing new reciprocal tariff rates specific to individual countries. All countries not listed in the announcement remain subject to a 10% "baseline" reciprocal tariff except for Canada, Mexico, North Korea, Russia, and Belarus. As it pertains to the countries where we manufacture solar modules, reciprocal tariff rates apply to Vietnam (20%), India (25%), and Malaysia (19%). The executive order also imposes an additional duty of 40% instead of the reciprocal tariff that would normally apply for any article that U.S. Customs and Border Protection determines has been transshipped to evade the reciprocal tariffs. Effective August 27, 2025, the U.S. President imposed an additional 25% tariff on India over its purchases of Russian oil, resulting in an overall rate of 50%. For more information about this development, see Part II. "Other Information" Item 1A. "Risk Factors – 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."

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *United States.* Effective June 4, 2025, the U.S. President increased tariffs on imported aluminum and steel articles under Section 232 of the Trade Expansion Act of 1962 ("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 Part II. "Other Information" Item 1A. "Risk Factors – 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."

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;*• 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. Since these export controls came into effect, we have assembled a cross-functional team to interpret the export controls 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.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *United States.* In April 2024, the American Alliance for Solar Manufacturing Trade Committee, which includes First Solar, filed a set of antidumping and countervailing duty ("AD/CVD") petitions with the U.S. Department of Commerce ("USDOC") and the U.S. International Trade Commission ("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 Part II. "Other Information" Item 1A. "Risk Factors – 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."

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *India*. The Approved List of Models and Manufacturers ("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 Ministry of New and Renewable Energy ("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. For more information about the ALMM, see Part II. "Other Information" Item 1A. "Risk Factors – 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."

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 September 30, 2025, we had entered into contracts with customers for the future sale of 53.7 GW of solar modules for an aggregate transaction price of $16.4 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 23.6 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 September 30, 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 price adjustments associated with sales freight in excess of defined thresholds and/or favorable or unfavorable price adjustments associated with changes to (i) certain commodity prices, (ii) the module wattage committed for delivery, (iii) the volume of modules sold that meet certain U.S. domestic content requirements, and (iv) certain tariff structures within a defined threshold. As a result, the revenue recognized from such contracts may increase or decrease in future periods relative to the original transaction price.

<u>[**Table of Contents**](#iacbb247b2553403b9d641c6defc6042c_7)</u>

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 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, therefore reducing future sales of solar modules. Furthermore, our ability to subsequently resell solar modules sold under terminated and/or renegotiated contracts may be constrained, such as by the project lead times of our customers, under-allocation of certain solar modules, and other factors. For example, on September 30, 2025, First Solar filed a complaint in the Supreme Court of the State of New York seeking monetary damages asserting that a certain major oil and gas customer breached its 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 II. "Other Information" Item 1. "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 recently identified manufacturing issues affecting certain Series 7 modules may adversely impact the average selling prices of our modules or the carrying value of our inventories. These manufacturing issues may also increase product warranty claims by our customers to resolve the premature power loss in affected modules. 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" of our Annual Report on Form 10-K for the year ended December 31, 2024.

We continue to increase the nameplate production capacity of our existing manufacturing facilities by improving our production throughput, increasing module wattage, and reducing manufacturing yield losses. Additionally, we are in the process of expanding our domestic manufacturing capacity, which includes capacity expansions at certain existing facilities. 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" of our Annual Report on Form 10-K for the year ended December 31, 2024.

***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. Third-party customers of this segment include system developers, independent power producers, utilities, commercial and industrial companies, and other system owners and operators.

***Net Sales***

During the three and nine months ended September 30, 2025, we sold the majority of our solar modules to developers and operators of systems in the United States, and substantially all of our module sales 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 following table shows net sales for the three and nine months ended September 30, 2025 and 2024:

---

Net sales increased $707.2 million for the three months ended September 30, 2025 compared to the three months ended September 30, 2024 primarily due to a 79.1% increase in the volume of modules sold to third parties and the prior period reduction in revenue related to manufacturing issues affecting certain Series 7 modules manufactured in 2023 and 2024.

------

<u>[**Table of Contents**](#iacbb247b2553403b9d641c6defc6042c_7)</u>

Net sales increased $844.3 million for the nine months ended September 30, 2025 compared to the nine months ended September 30, 2024 primarily due to a 30.3% increase in the volume of modules sold to third parties, an increase of $49.8 million in revenue associated with certain customer contract terminations, and the prior period reduction in revenue for the manufacturing issues discussed above.

***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 shipping, logistics, warranties, and solar module collection and recycling (excluding accretion).

Cost of sales increased $541.8 million, or 122.5%, and increased 11.9 percentage points as a percent of net sales for the three months ended September 30, 2025 compared to the three months ended September 30, 2024. The increase in cost of sales was primarily driven by (i) higher production costs of $453.3 million due to an increase in the volume of modules sold, (ii) higher logistics costs of $121.9 million, which includes tariffs, detention, and demurrage charges; and (iii) higher module storage costs of $43.8 million. These increases were partially offset by (iv) a higher volume of modules sold qualifying for the advanced manufacturing production credit under Section 45X of the IRC, which decreased cost of sales by $130.2 million.

Cost of sales increased $679.5 million, or 48.5%, and increased 6.8 percentage points as a percent of net sales for the nine months ended September 30, 2025 compared to the nine months ended September 30, 2024. The increase in cost of sales was primarily driven by (i) higher production costs of $532.2 million due to an increase in the volume of modules sold; (ii) higher logistics costs of $248.9 million, which includes tariffs, detention, and demurrage charges; (iii) higher production costs of $113.7 million, largely due to a higher sales mix of U.S.-produced modules; and (iv) higher module storage costs of $99.0 million. These increases were partially offset by (v) a higher volume of modules sold qualifying for the advanced manufacturing production credit under Section 45X of the IRC, which decreased cost of sales by $355.5 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.

The following table shows gross profit for the three and nine months ended September 30, 2025 and 2024:

---

Interest income for the three months ended September 30, 2025 was consistent with the three months ended September 30, 2024.

Interest income for the nine months ended September 30, 2025 decreased compared to the nine months ended September 30, 2024 due to lower balances of marketable securities and time deposits. These decreases were partially offset by higher interest earned on late customer payments.

***Interest Expense, Net***

Interest expense, net primarily comprises interest incurred on debt. We may capitalize interest expense to our property, plant and equipment when such costs qualify for interest capitalization, which reduces the amount of net interest expense reported in any given period.

---

Interest expense, net for the three and nine months ended September 30, 2025 increased compared to the three and nine months ended September 30, 2024 primarily due to the accretion of discounts on trade receivables factored with recourse, which are accounted for as secured borrowings.

***Other Expense, Net***

Other expense, net primarily comprises miscellaneous items and financing fees.

***Income Tax Expense***

Income tax expense or benefit, deferred tax assets and liabilities, and liabilities for unrecognized tax benefits reflect our best estimate 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.

The following table shows income tax expense for the three and nine months ended September 30, 2025 and 2024:

| Effective tax rate | 1.0% | 4.4% |  |  | 2.2% | 6.4% |  |  |

---

Our tax rate is affected by the advanced manufacturing production credit under Section 45X and recurring items such as tax rates in foreign jurisdictions and the relative amounts of income we earn in those jurisdictions. The rate is also affected by discrete items that may occur in any given period but are not consistent from period to period. During the nine months ended September 30, 2024, we reversed our position to indefinitely reinvest the accumulated earnings of a foreign subsidiary and recorded discrete tax expense of approximately $6 million.

Income tax expense for the three months ended September 30, 2025 decreased compared to the three months ended September 30, 2024 primarily due to (i) the relative amounts of advanced manufacturing production credits earned in each period and (ii) a discrete tax benefit associated with the acceptance of a filing position on an amended tax return in a foreign jurisdiction, partially offset by (iii) higher pretax income and (iv) higher losses in certain jurisdictions for which no tax benefit could be recorded.

Income tax expense for the nine months ended September 30, 2025 decreased compared to the nine months ended September 30, 2024 primarily due to (i) the relative amounts of advanced manufacturing production credits earned in each period, (ii) a discrete tax benefit associated with the acceptance of a filing position on an amended tax return in a foreign jurisdiction, and (iii) the prior year discrete tax expense associated with the reversal of our indefinite reinvestment assertion described above; partially offset by (iv) higher pretax income and (v) higher losses in certain jurisdictions for which no tax benefit could be recorded.

**Critical Accounting Policies and Estimates**

In preparing our condensed consolidated financial statements in conformity with 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. We believe the judgments and estimates involved in accrued solar module collection and recycling, product warranties, and government grants have the greatest potential impact on our condensed consolidated financial statements. 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. For a description of the accounting policies that require the most significant judgment and estimates in the preparation of our condensed consolidated financial statements, refer to our Annual Report on Form 10-K for the year ended December 31, 2024. There have been no material changes to our accounting policies during the nine months ended September 30, 2025.

**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. ASU 2023-09 is effective for public companies for annual periods beginning after December 15, 2024. We plan to present the expanded income tax disclosures in our consolidated financial statements for the year ending December 31, 2025.

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. 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.

**Liquidity and Capital Resources**

As of September 30, 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, we have availability under our Revolving Credit Facility, which remains unused as of September 30, 2025, as well as various trade receivables factoring arrangements with financial institutions. 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 Revolving 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 construction activities and purchases of manufacturing equipment for our newest manufacturing facilities 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 September 30, 2025, we had $2.0 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) higher cash receipts from module sales, including advance payments for future sales, (ii) receipts from trade receivables factoring, and (iii) proceeds from the sale of Section 45X tax credits, partially offset by (iv) increases in payments made to suppliers, (v) purchases of property, plant and equipment for our U.S. facilities, (vi) various operating expenditures, and (vii) certain advance payments for raw materials. As of September 30, 2025 and December 31, 2024, $388.1 million and $694.0 million of our cash, cash equivalents, and marketable securities, respectively, were held by our foreign subsidiaries and were primarily based in U.S. dollar and Indian Rupee 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 September 30, 2025, but we may choose to reevaluate this intent in one or more jurisdictions in the future. 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 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 December 2024, we entered into two agreements for the sale of $857.2 million of Section 45X tax credits we generated during 2024 for aggregate cash proceeds of $818.6 million. We received initial cash proceeds of $616.0 million in December 2024 and received the remaining cash proceeds of $202.6 million in February 2025. In June 2025, we entered into an agreement for the sale of $311.9 million of Section 45X tax credits we generated during 2025 for aggregate cash proceeds of $296.3 million. We received the full cash proceeds in June 2025. In July 2025, we entered into an agreement for the sale of up to $391.0 million of Section 45X tax credits we expect to generate during 2025 for aggregate cash proceeds of up to $372.8 million. We received initial cash proceeds of $123.5 million and $124.2 million in July and October 2025, respectively, and we expect to receive the remaining cash proceeds in the fourth quarter of 2025. For more information about certain risks associated with the benefits available to us under the IRA, see Part II. "Other Information" Item 1A. "Risk Factors." See Note 5. "Government Grants" to our condensed 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. The capital expenditures necessary to expand our capacity were 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.

In addition to the expansion described above, we intend to increase the nameplate production capacity of our existing manufacturing facilities by improving our production throughput, increasing module wattage, and reducing manufacturing yield losses. During 2025, we expect to spend between $0.9 billion and $1.2 billion for capital expenditures, including the new facility mentioned above, investments in various R&D initiatives, and upgrades to machinery and equipment that we believe will further increase our module wattage and expand capacity and throughput at our facilities. 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" of our Annual Report on Form 10-K for the year ended December 31, 2024.

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 $319.9 million as of September 30, 2025 and decline over the remaining supply 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.

<u>[**Table of Contents**](#iacbb247b2553403b9d641c6defc6042c_7)</u>

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 September 30, 2025, such funds were comprised of restricted marketable securities of $215.5 million and associated restricted cash and cash equivalents of $6.2 million. As of September 30, 2025, our module collection and recycling liability was $145.1 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 September 30, 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 10. "Commitments and Contingencies" to our condensed consolidated financial statements for further information about our financial assurance related instruments.

***Cash Flows***

The following table summarizes key cash flow activity for the nine months ended September 30, 2025 and 2024 (in thousands):

---

| | | |
|:---|:---|:---|
| | **Nine Months Ended <br>September 30,** | **Nine Months Ended <br>September 30,** |
| | **2025** | **2024** |
| Net cash provided by operating activities | $815212 | $407003 |
| Net cash used in investing activities | (577934) | (1341921) |
| Net cash provided by (used in) financing activities | 124442 | (5879) |
| Effect of exchange rate changes on cash, cash equivalents, restricted cash, and restricted cash equivalents | 2021 | (2805) |
| Net increase (decrease) in cash, cash equivalents, restricted cash, and restricted cash equivalents | $363741 | $(943602) |

---

*Operating Activities*

The increase in net cash provided by operating activities was primarily driven by higher cash receipts from module sales, including advance payments for future sales, and receipts from factoring trade receivables, partially offset by higher payments made to suppliers.

*Investing Activities*

The decrease in net cash used in investing activities 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 provided by financing activities was primarily due to net proceeds from secured borrowings from trade receivables factoring with recourse and other borrowings under various debt agreements in the current period, partially offset by repayment of debt in the current period.

**Item 3. *Quantitative and Qualitative Disclosures about Market Risk***

There have been no material changes to the information previously provided under Item 7A. of our Annual Report on Form 10-K for the year ended December 31, 2024.

**Item 4. *Controls and Procedures***

**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 September 30, 2025 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.

**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" as defined in Exchange Act Rule 13a-15(f) and 15d-15(f) to determine whether any changes in our internal control over financial reporting occurred during the three months ended September 30, 2025 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 three months ended September 30, 2025.

**CEO and CFO Certifications**

We have attached as exhibits to this Quarterly Report on Form 10-Q the certifications of our Chief Executive Officer and Chief Financial Officer, which are required in accordance with the Exchange Act. We recommend that this Item 4. be read in conjunction with those certifications for a more complete understanding of the subject matter presented.

**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.

First Solar alleges that the JinkoSolar TOPCon products contain solar cells manufactured using a method claimed in the patent. First Solar seeks both monetary damages and injunctive relief. On June 27, 2025, JinkoSolar filed an answer to the complaint and counterclaims asserting that the patent-in-suit is not valid and that it is not infringed by JinkoSolar. On July 18, 2025, First Solar filed an answer to the counterclaims.

On July 18, 2025, JinkoSolar Co. Ltd. filed an *inter partes* review before the U.S. Patent and Trademark Office (the "USPTO") alleging First Solar's patent asserted in the District of Delaware litigation (the "'074 Patent") is invalid over certain prior art. On September 29, 2025, First Solar filed a brief requesting that the *inter partes* review be discretionarily denied.

*Mundra*

On April 15, 2025, Mundra Solar PV Limited ("Mundra") filed suit in the district court of the District of Delaware seeking declaratory judgment that it does not infringe two of First Solar's patents (the '074 Patent and the '732 Patent) through its manufacture, import, use, sale, and offering for sale of certain TOPCon solar products. On August 1, 2025, First Solar filed an answer to the compliant and pleaded counterclaims alleging that Mundra as well as its affiliates Mundra Solar Energy Ltd., Adani Solar USA Inc., Adani Solar USA LLC, and Adani Solar infringe the two First Solar patents. On September 22, 2025, Mundra filed an answer to First Solar's counterclaims and added counterclaims asserting that the First Solar patents are invalid. On October 3, 2025, Adani Solar USA Inc. and Adani Solar USA LLC (collectively, "Adani Solar USA") filed a motion to dismiss First Solar's counterclaims with respect to Adani Solar USA. On October 8, 2025, First Solar filed an answer to Mundra's counterclaims. First Solar filed an opposition to the motion to dismiss on October 17, 2025, and Adani Solar USA filed a reply brief on October 24, 2025.

On August 15, 2025, Mundra filed an *inter partes* review before the USPTO alleging that First Solar's '732 Patent is invalid over certain prior art. On October 17, 2025, First Solar filed a brief requesting that the *inter partes* review be discretionarily denied.

On August 22, 2025, Canadian Solar (USA) Inc. filed an *inter partes* review before the USPTO alleging that First Solar's '074 Patent is invalid over certain prior art. On October 24, 2025, First Solar filed a brief requesting that the *inter partes* review be discretionarily denied.

*Customer Contract Dispute*

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 (together, the "Defendants") 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 master supply agreements. As a result of the failure to cure such breaches, First Solar terminated the various master supply agreements, which triggered certain contractual termination payment provisions amounting to $384.6 million, of which First Solar recognized $61.0 million in revenue during the quarter related to advance payments previously received from the Defendants. First Solar seeks monetary damages, demanding payment from the Defendants for the remaining termination payments of $323.6 million along with certain other receivables for solar modules previously delivered to the Defendants. The Defendants' answers to the complaint are due on October 31, 2025.

See Note 10. "Commitments and Contingencies" under the heading "Legal Proceedings" of our condensed consolidated financial statements for other legal proceedings and related matters.

**Item 1A. *Risk Factors***

In addition to the other information set forth in this report, you should carefully consider the factors discussed in Item 1A. "Risk Factors" of our Annual Report on Form 10-K for the year ended December 31, 2024, which could materially affect our business, financial condition, results of operations, and cash flows. The risks described in our Annual Report on Form 10-K are not the only risks we face. Additional risks and uncertainties not currently known to us or that we currently consider immaterial may also materially adversely affect our business, financial condition, results of operations, and cash flows. Except for the risk factors set forth below, there have been no material changes in the risk factors contained in our Annual Report on Form 10-K.

***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 feed-in-tariff structures, rebates, tax incentives, and other incentives to end users, distributors, system integrators, and manufacturers of PV solar products. Many of these incentive programs expire, phase down over time, require renewal by the applicable authority, or may be amended. To the extent government incentive programs are reduced earlier than previously expected, are changed retroactively, or are not renewed, such changes have and could negatively impact demand and/or price levels for our solar modules, lead to a reduction in our net sales, and adversely impact our operating results.

Current regulatory policies, or any future changes or threatened changes to such policies, including those changes as a result of the U.S. presidential administration and control of the U.S. Congress, may subject us to significant risks, including the following:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• a reduction or removal of certain energy programs and initiatives and the incentives they provide may diminish the market for future solar energy off-take agreements, slow the retirement of aging fossil fuel plants, including the retirements of coal generation plants, and reduce the ability for solar project developers to compete for off-take agreements, which may reduce PV solar module sales;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• any limitations on the value or availability to manufacturers or potential investors of tax incentives that benefit solar energy production, sales, or projects, such as the Section 45X advanced manufacturing production credit, ITC, and PTC, as seen in the accelerated termination of certain energy tax credits under the "One Big Beautiful Bill" the U.S. President signed into law on July 4, 2025, could result in reducing such manufacturers' or investors' economic returns and could cause a reduction in the availability of financing, thereby reducing demand for PV solar modules;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• any incentives contingent upon domestic production of modules, such as tax incentives set forth under the IRA, could limit our ability to sell modules manufactured in certain foreign jurisdictions, which may adversely impact our module average selling prices and could require us to record significant charges to earnings should we determine that the manufacturing facilities and equipment in such foreign jurisdictions are impaired; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• any effort to overturn federal and state laws, regulations, or policies that are supportive of solar energy generation or that remove costs or other limitations on other types of electricity generation that compete with solar energy projects could negatively impact our ability to compete with traditional forms of electricity generation and materially and adversely affect our business.

Application of trade laws may also adversely impact, either directly or indirectly, our operating results; for example, by impacting our customers' project costs, profitability, and their demand for our modules; or by impacting our own costs or disrupting our manufacturing or supply chains, and consequently negatively impacting demand and/or price levels for our solar modules, reducing our net sales, or affecting potential profitability of fulfilling customer contracts. We are therefore potentially subject to various risks, which include the following:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• any tariffs that reduce the profitability of contracts, whereby the cost of tariffs exceeds the amount able to be, or willing to be, absorbed by either us or the customer under the provisions of the contract and may lead to us or the customer cancelling such contract, potentially resulting in the reduction of future revenue, the loss of the contractual right to a termination payment from the customer, and potentially the required return of a previously received customer down payment;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• any reciprocal or other tariffs may place burdens on our customers' supply chains exclusive of module import costs, including through increased costs of trackers, inverters, transformers, and other imported equipment, which are often heavily dependent on Chinese supply chains. These and other costs could result in an inability for certain projects to generate profitable returns, and may lead to the delay or abandonment of such projects, thereby reducing or removing demand for currently contracted PV module sales; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• any reduction in our ability to profitably import modules from our international manufacturing locations as a result of tariffs or other trade laws could lead to us significantly reducing capacity utilization at certain international manufacturing facilities. Such underutilization may lead to potential impairment of certain international equipment and facilities and may also increase our selling costs and reduce our competitiveness in the market, thereby reducing demand for our modules.

In some instances, the application of trade laws is currently beneficial to us, and changes in their application could have an adverse impact. The overall impact of trade laws on our business depends on multiple factors, including their duration, their scope and potential expansion thereof, enforcement, retaliatory measures by impacted exporting countries, inflationary effects and broader macroeconomic responses, changes to consumer purchasing behavior, and the effectiveness of our responses in managing these impacts. Recent developments include the following:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *United States — Reciprocal Tariffs*. On April 2, 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 pursuant to the International Emergency Economic Powers Act of 1977 ("IEEPA"). On April 9, 2025, the U.S. President paused the additional, higher tariffs on most countries for 90 days. 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 was extended for an additional 90 days on August 12, 2025. On July 2, 2025, the U.S. President announced that the United States and Vietnam had reached a preliminary trade agreement, which placed a 20% tariff on all products of Vietnam and a 40% tariff on all "transshipped" goods. On July 31, 2025, the U.S. President issued an executive order detailing new reciprocal tariff rates specific to individual countries. All countries not listed in the announcement remain subject to a 10% "baseline" reciprocal tariff except for Canada, Mexico, North Korea, Russia, and Belarus. As it pertains to the countries where we manufacture solar modules, reciprocal tariff rates apply to Vietnam (20%), India (25%), and Malaysia (19%). The executive order also imposes an additional duty of 40% instead of the reciprocal tariff that would normally apply for any article that U.S. Customs and Border Protection determines has been transshipped to evade the reciprocal tariffs. Effective August 27, 2025, the U.S. President imposed an additional 25% tariff on India over its purchases of Russian oil, resulting in an overall rate of 50%. The additional, higher tariffs on imports from these countries increase the costs of our solar modules manufactured in these countries with respect to our U.S. market. Further, such circumstances have and may continue to impact our ability to sell certain modules into the United States and therefore have and may continue to also impact the operational status of certain of our international manufacturing facilities. As a result, our operating results have and may continue to be adversely impacted by these tariffs.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;*• United States — Tariffs on Certain Imported Crystalline Silicon PV Cells and Modules.* The United States currently imposes different types of tariffs and/or other trade remedies on certain imported crystalline silicon PV cells and modules from various countries. In February 2022, the previous U.S. President proclaimed a four-year extension of a global safeguard measure imposed pursuant to Section 201 of the Trade Act of 1974 that provides for tariffs on imported crystalline silicon solar modules and a tariff-rate quota on imported crystalline silicon solar cells. Thin film solar cell products, such as our CdTe technology, are specifically excluded from the tariffs. The extension measure's tariff rate was originally set at 14.75%, with annual reductions of 0.25 percentage points over the remainder of its four-year term. The current rate is 14%. The extension measure also provides an annual tariff-rate quota, whereby tariffs apply to imported crystalline silicon solar cells above the first 5.0 GW of imports. In August 2024, the previous U.S. President increased the tariff-rate quota from 5.0 GW to 12.5 GW.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *United States — Additional Tariffs on Certain Chinese Imports*. The United States currently imposes tariffs on various articles imported from China, including tariffs of 50% on crystalline silicon solar cells and tariffs of 25% on modules, based on an investigation under Section 301 of the Trade Act of 1974. In February 2025, the U.S. President announced an additional 10% tariff on all imports from China, which is related to the national security threat posed by China's trade in fentanyl and other illegal narcotics. This 10% tariff was subsequently doubled to 20% in March 2025 and applies in addition to the 25% tariffs under Section 301 and ordinary customs duties and AD/CVDs. Further, as discussed above, in April 2025, the United States imposed an additional reciprocal tariff on China. Effective May 14, 2025, the United States agreed to lower this additional reciprocal tariff rate to 10% for 90 days. On August 12, 2025 this initial 90-day period was extended and the 10% reciprocal tariff rate is currently set to remain in place until November 10, 2025. On May 28, 2025, the Court of International Trade issued a decision enjoining the U.S. presidential administration's tariffs imposed under the IEEPA, including the 30% tariffs imposed on China. This ruling was subsequently upheld by the Court of Appeals for the Federal Circuit on August 29, 2025. The Supreme Court has agreed to hear this challenge, with oral arguments set to take place on November 5, 2025. Our operating results could be adversely impacted if the IEEPA tariffs on China were to be terminated or reduced.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *United States — Port Fees on Certain Chinese Vessel Operators and Chinese Vessel Owners.* On April 17, 2025, the Office of the U.S. Trade Representative published a notice of final action based on an investigation under Section 301 of the Trade Act of 1974 into China's targeting of the maritime, logistics, and shipbuilding sectors for dominance. The action imposes new port fees on Chinese vessel operators and/or Chinese vessel owners as well as on non-Chinese operators of Chinese-origin vessels beginning on October 14, 2025. The level of fees is on a sliding scale per net ton or, in the case of non-Chinese operators, the higher of a net ton or container-based fee. Such fees may impact our logistics services and consequently impact our profitability and results of operations.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *United States — Tariffs on Certain Foreign-imported Aluminum, Steel, and Copper.* 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. Such tariffs and policies, or any other U.S. or global trade remedies or other trade barriers, may directly or indirectly affect U.S. or global markets for solar energy and our business, financial condition, and results of operations.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *United States — Potential Tariffs on Processed Critical Minerals and Derivative Products, Polysilicon, Robotics and Industrial Machinery.* 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. The scope of these investigations is potentially broad and may cover materials and equipment used in solar module manufacturing. These investigations may result in the imposition of tariffs or import restrictions, or may remove barriers on the imports of competitor products and materials, all of which could negatively impact demand and/or price levels for our solar modules and limit our growth, lead to a reduction in our net sales, or increase our costs, thereby adversely impacting our operating results.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *United States — Antidumping and Countervailing Duties on Certain Imported Crystalline Silicon PV Cells and Modules.* The United States currently imposes AD/CVDs on certain imported crystalline silicon PV cells and modules from China and Taiwan. Such AD/CVDs can change over time pursuant to annual administrative reviews conducted by the USDOC, and a decline in duty rates or USDOC failure to fully enforce U.S. AD/CVD laws could have an adverse impact on our operating results. In August 2023, the USDOC issued final affirmative circumvention rulings, finding that solar modules completed in Cambodia, Malaysia, Thailand, and Vietnam using parts and components produced in China circumvent the pre-existing AD/CVD orders on China. Such duties apply to circumventing imports on or after June 6, 2024, as well as any circumventing imports prior to that date that were not used or installed on or before December 3, 2024. Our operating results could be adversely impacted if the USDOC and other U.S. government agencies do not enforce the affirmative circumvention rulings as expected or if pending litigation challenges result in a modification of the rulings. Conversely, effective enforcement could positively impact our operating results.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *United States — Antidumping and Countervailing Duties on Certain Traded Solar Products.* 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. On April 21, 2025, the USDOC announced final determinations in the AD/CVD investigations. Final AD/CVD rates ranged from de minimis to over 3,400%, depending on the particular foreign producer. On June 9, 2025, the USITC notified USDOC of its final affirmative determinations in the AD/CVD investigations. AD/CVD orders, including the assessment of AD/CVDs 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 August 2025, the USITC issued affirmative preliminary determinations. The USDOC is expected to issue its preliminary countervailing duty determinations in December 2025 and preliminary antidumping duty determinations in February 2026.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *India — Domestic and Foreign Imports.* 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. In April 2024, the government of India reimposed the ALMM, thereby requiring solar project developers to procure qualifying modules from companies on the list, which includes our Indian manufacturing facility. Also in April 2024, the ALMM was amended to include specific minimum conversion efficiency thresholds for CdTe solar technologies starting at 18% for solar lighting, 18.5% for rooftop applications, and 19% for utility-scale applications. 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. In May 2025, the ALMM was amended to lower the minimum efficiency thresholds for PV modules used in off-grid applications. 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. Our operating results could be adversely impacted if the ALMM requirements are significantly relaxed to allow modules, solar cells, or certain other key module components to be imported from other countries.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *India — Import Duty Tariffs.* In April 2022, the Indian government began imposing import duty tariffs of 40% on solar modules and 25% on solar cells. In connection with such April 2022 tariffs, the Indian government also implemented a regulation mandating that any solar project with federal utility, state utility, or commercial and industrial off-takers that interconnects through government owned transmission lines only use solar modules from manufacturers included in the ALMM, and a requirement that all federal procurement of solar modules be only from cells and modules produced domestically. However, in February 2025, the Indian government began imposing import duty tariffs of 20% each on solar modules and cells and levied additional tax on certain commercial agricultural production, which tax included 20% on solar modules and 7.5% on solar cells. Therefore, the aggregate impact on the import of solar modules and cells is 40% and 27.5%, respectively.

These examples show that established markets for PV solar development face uncertainties arising from policy, regulatory, and governmental actions. While the expected potential of the markets we are targeting is significant, policy promulgation and market development are especially vulnerable to governmental inertia, political instability, changing government policy and priorities, the imposition or lowering of trade remedies and other trade barriers, geopolitical risk, fossil fuel subsidization, potentially stringent localization requirements, and limited available infrastructure. Any negative impacts from changes in policy, regulatory, and governmental actions could negatively affect our business, reduce our net sales, profitability and/or market share, and consequently adversely affect our results of operations, prospects, and financial condition.

***The loss of any of our large customers, or the inability of our customers and counterparties to perform under their contracts with us, including through terminations by customers of any contract in part or in full, has reduced and, in the future, could significantly reduce our net sales and negatively impact our results of operations.***

Our customers include developers and operators of systems, utilities, independent power producers, commercial and industrial companies, and other system owners, who may experience intense competition at the system level, thereby constraining the ability for such customers to sustain meaningful and consistent profitability. The loss of any of our large customers, their inability to perform under their contracts, or their default in payment has reduced and, in the future, could significantly reduce our net sales and/or adversely impact our operating results. 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. These contract breaches and renegotiations have and may continue to reduce the volume of modules sold under the relevant contracts, postpone delivery schedules, and/or otherwise decrease the revenue we realize under these contracts and, correspondingly, negatively impact, potentially significantly, our results of operations. This includes cases where our ability to subsequently resell solar modules sold under terminated and/or renegotiated contracts may be constrained, such as by the project lead times of our customers, under-allocation of certain solar modules, and other factors. For example, on September 30, 2025, First Solar filed a complaint in the Supreme Court of the State of New York seeking monetary damages asserting that a certain major oil and gas customer breached its 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. See Part II "Other Information" Item 1. "Legal Proceedings" for additional information. Additionally, although we require some form of payment security from our customers, such as cash deposits, parent guarantees, bank guarantees, surety bonds, or commercial letters of credit, in the event the providers of such payment security fail to perform their obligations, our operating results could be adversely impacted.

***Our failure to protect or successfully commercialize our intellectual property rights may undermine our competitive position, and litigation to protect our intellectual property rights or defend against third-party allegations of infringement may be costly.***

Protection of our proprietary processes, methods, and other technology is critical to our business. Failure to protect and monitor the use of our existing intellectual property rights or to successfully commercialize future intellectual property rights could result in the loss of valuable technologies. We rely primarily on patents, trademarks, trade secrets, copyrights, and contractual restrictions to protect our intellectual property. We regularly file patent applications to protect certain inventions arising from our R&D and are currently pursuing such patent applications in various countries in accordance with our strategy for intellectual property in that jurisdiction. Our existing patents and future patents could be challenged, invalidated, circumvented, or rendered unenforceable. Our pending patent applications may not result in issued patents, or if patents are issued to us, such patents may not be sufficient to provide meaningful protection against competitors or against competitive technologies.

We also rely on unpatented proprietary manufacturing expertise, continuing technological innovation, and other trade secrets to develop and maintain our competitive position. Although we generally enter into confidentiality agreements with our associates and third parties to protect our intellectual property, such confidentiality agreements are limited in duration and could be breached and may not provide meaningful protection for our trade secrets or proprietary manufacturing expertise. Adequate remedies may not be available in the event of unauthorized use or disclosure of our trade secrets and manufacturing expertise. In addition, others may obtain knowledge of our trade secrets through independent development or legal means. The failure of our patents or confidentiality agreements to protect our processes, equipment, technology, trade secrets, and proprietary manufacturing expertise, methods, and compounds could have a material adverse effect on our business. In addition, effective patent, trademark, copyright, and trade secret protection may be unavailable or limited in some foreign countries, especially any developing countries into which we may expand our operations. In some countries, we have not applied for patent, trademark, or copyright protection.

Third parties may infringe or misappropriate our proprietary technologies or other intellectual property rights, which could have a material adverse effect on our business, financial condition, and operating results. Policing unauthorized use of proprietary technology can be difficult and expensive. Additionally, litigation may be necessary to enforce our intellectual property rights, protect our trade secrets, or determine the validity and scope of the proprietary rights of others. For example, on February 25, 2025, we filed a lawsuit in the United States District Court for the District of Delaware against JinkoSolar and its related entities alleging infringement of certain of our U.S. TOPCon patents. On April 15, 2025, Mundra, whose parent corporation is Adani Green Technology Limited, filed a lawsuit in the United States District Court for the District of Delaware seeking a judgment declaring that it has not infringed two of our U.S. TOPCon patents. Further, on May 9, 2025, we filed a lawsuit in the United States District Court for the District of Delaware against Canadian Solar and its related entities alleging infringement of certain of our U.S. TOPCon patents. We cannot ensure that the outcome of such litigation will be in our favor, and such litigation may be costly and may divert management attention and other resources away from our business. An adverse determination in any such litigation or the related *inter partes* reviews may impair our intellectual property rights and may harm our business, prospects, and reputation. In addition, we have no insurance coverage against such litigation costs and would have to bear all costs arising from such litigation to the extent we are unable to recover them from other parties.

***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.***

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. The provisions of the IRA are generally effective for tax years beginning after 2022. 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. 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.

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. For example, in June 2025, December 2024, and December 2023, we entered into various agreements for the sales of Section 45X tax credits generated in 2025, 2024, and 2023, respectively. For further information, see Item 2. "Management's Discussion and Analysis of Financial Condition and Results of Operations – Liquidity and Capital Resources." However, there is no assurance that future sales of tax credits will be available to us on similar or alternative terms or at all. In connection with the sale of Section 45X tax credits, we agree to indemnify the purchasers for certain losses they may suffer, including as a result of any inability to claim all or any portion of the Section 45X tax credits sold, subject to certain exceptions and limitations. If we are required to make an indemnification payment to a purchaser of a tax credit it may have a material impact on our results of operations and financial condition. Furthermore, 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.

Certain developments to technical guidance and regulations include the following:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• In March 2024, the U.S. Treasury Department and the IRS issued final regulations on the direct payment election under Section 6417 of the IRC. The final regulations apply to tax years ending on or after March 11, 2024, but taxpayers may choose to apply the rules in the final regulations in taxable years ending before March 11, 2024, provided the final regulations are applied in their entirety and in a consistent manner. The final regulations mostly adopted and confirmed the proposed regulations previously issued in June 2023.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• In April 2024, the U.S. Treasury Department and the IRS issued final regulations on the elective transfer provisions under Section 6418 of the IRC. The final regulations apply to taxable years ending on or after April 30, 2024, but taxpayers may choose to apply the rules in the final regulations in taxable years ending before April 30, 2024, provided the final regulations are applied in their entirety and in a consistent manner. The final regulations mostly adopted and confirmed the proposed regulations previously issued in June 2023.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• In October 2024, the U.S. Treasury Department and the IRS issued final regulations on the Section 45X credit confirming key aspects of the credit, including (i) that a vertically-integrated solar module manufacturer is entitled to the sum of the credit amounts for each eligible component that is integrated into the solar module, (ii) the determination of the credit amounts based on standard test conditions, and (iii) the definition of a Section 45X manufacturing facility.

Any modifications to the law or its effects arising, for example, through (i) technical guidance and regulations from the IRS and U.S. Treasury Department, including the certain aspects disclosed above, (ii) subsequent amendments to or interpretations of the law by the IRS, the U.S. Treasury Department, or the courts, (iii) future laws or regulations rendering certain provisions of the IRA less effective or ineffective, in whole or in part, and/or (iv) changes to U.S. government priorities, policies, and/or initiatives as a result of the current U.S. presidential administration and control of the U.S. Congress, could result in changes to the expected and/or actual benefits in the future, which could have a material adverse effect on demand and/or price levels for our solar modules, our net sales, and future expansion plans within the United States, and/or otherwise adversely impact our business, financial condition, and results of operations.
