MAGNACHIP SEMICONDUCTOR CORPORATION AND SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
(TABULAR DOLLARS IN THOUSANDS, EXCEPT SHARE DATA)
1. Business, Basis of Presentation and Significant Accounting Policies
Business
Magnachip Semiconductor Corporation (together with its subsidiaries, the “Company”) is a designer and manufacturer of analog and mixed-signal power semiconductor platform solutions for various applications, including industrial, automotive, communication, consumer and computing.
The Company develops and manufactures Power discrete products and develops Power integrated circuit (“IC”) products. Power discrete products include metal oxide semiconductor field effect transistors (“MOSFETs”) and insulated-gate bipolar transistors (“IGBTs”) for a range of devices, including televisions, smartphones, mobile phones, wearable devices, desktop personal computers (“PCs”), notebook PCs, tablet PCs, servers, other consumer electronics, as well as automotive and industrial applications such as power suppliers,
e-bikes,
solar inverters, LED lighting and motor drives. Power IC products include
AC-DC/DC-DC
converters, LED drivers, regulators, power management integrated circuits (“PMICs”) and level shifter for a range of devices, including televisions, wearable devices, notebooks, tablet PCs and others consumer electronics, as well as automotive applications.
In 2024, the Power IC business was operated by Magnachip Mixed-Signal, Ltd. (“MMS”), which later transferred the business to Magnachip Semiconductor, Ltd. (“MSK”) effective January 1, 2025, pursuant to an intercompany business transfer agreement executed between MMS and MSK. The transfer was based on the mutual understanding that consolidating the Power IC and Power Analog Solutions businesses under a single company would create a more effective framework for expanding and strengthening the Company’s business for Power products.
Basis of Presentation
The accompanying unaudited interim consolidated financial statements of the Company have been prepared in accordance with generally accepted accounting principles in the United States of America (“U.S. GAAP”). These interim consolidated financial statements include normal recurring adjustments and the elimination of all intercompany accounts and transactions which are, in the opinion of management, necessary to provide a fair statement of the Company’s financial condition and results of operations for the periods presented. These interim consolidated financial statements are presented in accordance with Accounting Standards Codification (“ASC”) 270, “Interim Reporting” and, accordingly, do not include all of the information and note disclosures required by U.S. GAAP for complete financial statements, except for the changes below.
The Company has reclassified certain prior year amounts to conform to the current year’s presentation for discontinued operations to reflect a plan to shut down the Company’s Display business and transition into a pure-play Power company. The assets and liabilities related to the discontinued Display business have not been reclassified on the consolidated balance sheets as of September 30, 2025. See Note 2 “Discontinued Operations” for additional information. The consolidated statements of cash flows have not been adjusted to separately disclose cash flows related to discontinued operations, but the material items in the operating and investing activities of cash flows relating to discontinued operations are disclosed in Note 2. Unless otherwise stated, information in these notes to consolidated financial statements relates to the Company’s continuing operations and excludes the discontinued operations.
There have been no material changes to the Company’s significant accounting policies as of and for the nine months ended September 30, 2025, except for those related to discontinued operations as described below, as compared to the significant accounting policies described in the Company’s Annual Report on Form
10-K
for the fiscal year ended December 31, 2024.

2. Discontinued Operations
On March 7, 2025, the Company’s Board of Directors authorized a strategy to transition to a pure-play Power company, focusing its investments on the Power Analog Solutions and Power IC businesses to enhance profitability and maximize shareholder value. As part of this strategy, the Company explored all strategic options including a sale, merger, joint venture, licensing, and wind-down for its Display business (Display IC products). However, the Company was not able to consummate a transaction following several months of discussions with several interested parties on terms that the Company’s Board of Directors believed were in the best interests of the Company and its stockholders.
Accordingly, on April 6, 2025, the Company’s Board of Directors unanimously approved the plan to shut down the Company’s Display business (the “Discontinued Business”), including the liquidation of MMS, the Company’s indirect wholly owned subsidiary that operated the Discontinued Business. As a result, the Display business qualifies as a discontinued operation in accordance with ASC
205-20.
The following table summarizes the results from discontinued operations, net of tax, for the three and nine months ended September 30, 2025 and 2024 (in thousands):

Capital expenditures |  | $ | (99 | ) |  | $ | (1,597 | )

Although the Company has ceased active operations of its Display business, it continues to have limited involvement after the shutdown. Specifically, the Company’s Korean subsidiary, MSK, continues to fulfill remaining customer obligations, including the sale of certain “end of life” (“EOL”) Display products. A small team has been retained to manage the transition and to provide ongoing customer support.
As such, the result of these limited ongoing activities do not qualify for presentation as part of continuing operations and are instead presented as part of discontinued operations. The following table presents the revenue, gross profit and operating expenses related to the Company’s continuing involvement with the Discontinued Business for the periods presented (in thousands):

|  | Three Months Ended |  |  | Nine Months Ended |
|  | September 30, 2025 |
Net sales |  | $ | 7,233 |  |  | $ | 9,551 |
Gross profit |  |  | 3,540 |  |  |  | 4,473 |
Operating expenses |  |  | 342 |  |  |  | 485 |

The sale of EOL Display products and the potential monetization of the intellectual property assets of the Discontinued Business are currently expected to generate cash inflow of approximately $20 million over a period of approximately 2 years from the second half of 2025, depending upon customer demand and monetization efforts of the Display intellectual property assets.
The total estimated cash cost of the liquidation is approximately $12 to $15 million, which is expected to be offset by the cash inflow that may be generated as described above. The
one-time
liquidation cost is expected to consist of statutory severance and other employee-related costs, contract termination charges and other associated costs. Of this estimated total cash cost, the Company paid $6.5 million of statutory severance and other employee-related costs in the second quarter of 2025. Further, the Company originally expected to pay certain contract termination charges in full along with the statutory severance and other employee-related costs, but negotiated with the respective vendors for those contract termination charges totaling $6.5 million to be paid over the duration of the remaining existing contract terms.

For derivative instruments that are designated and qualify as cash flow hedges, gains or losses on the derivative aside from components excluded from the assessment of effectiveness are reported as a component of accumulated other comprehensive income or loss (“AOCI”) and reclassified into earnings in the same period or periods during which the hedged transaction affects earnings. Gains and losses on the derivative, representing hedge components excluded from the assessment of effectiveness, are recognized in current earnings.

10. Accrued Severance Benefits
The majority of accrued severance benefits are for employees in the Company’s Korean subsidiaries. Pursuant to the Employee Retirement Benefit Security Act of Korea, eligible employees and executive officers with one or more years of service are entitled to severance benefits upon the termination of their employment based on their length of service and rate of pay. As of September 30, 2025, 97% of all employees of the Company were eligible for severance benefits.

The severance benefits funded through the Company’s National Pension Fund have been and will be used exclusively for payment of severance benefits to eligible employees. These amounts have been deducted from the accrued severance benefit balance.
Beginning in July 2018, the Company contributes to certain severance insurance deposit accounts a certain percentage of severance benefits that are accrued for eligible employees for their services from January 1, 2018 pursuant to Employee Retirement Benefit Security Act of Korea. These accounts consist of time deposits and other guaranteed principal and interest, and are maintained at insurance companies, banks or security companies for the benefit of employees. The Company deducts the contributions made to these severance insurance deposit accounts from its accrued severance benefits.

11. Long-Term Borrowings
Term Loan
On March 26, 2024, Magnachip Semiconductor, Ltd., a Korean limited liability company (“MSK”) and indirect wholly owned subsidiary of the Company, executed a Standard Credit Agreement (together with its General Terms and Conditions, the “Loan Agreement”) with Korea Development Bank (“KDB”). In connection with the Loan Agreement, on March 26, 2024, MSK entered into a
Kun-Pledge
(Mortgage) Agreement (the “Pledge Agreement”) with KDB pursuant to which MSK pledged its real property and buildings located in Gumi, Korea (“Fab 3 properties”) in favor of KDB.
The Loan Agreement provides for a working capital term loan (the “Term Loan”) of KRW 40,000,000,000 (approximately $29,835 thousand based on the KRW/USD exchange rate of
1,340.7:1
as of March 26, 2024 as quoted by KEB Hana Bank), which was funded in full to MSK on March 26, 2024.
The Term Loan bears interest at a variable rate equal to the
3-month
CD rate quoted by KDB, plus 1.21%, which rate is adjusted quarterly. The initial interest rate on the Term Loan was 4.86% per annum. The Term Loan requires monthly interest-only payments and matures on March 26, 2027, at which time the full principal balance will be due and payable. All obligations of MSK under the Loan Agreement and the Term Loan are secured by the Fab 3 properties pursuant to the Pledge Agreement.
As of September 30, 2025, the outstanding principal amount under the Term Loan was approximately $28,527 thousand.
CAPEX Loans
On December 16, 2024, MSK executed a Standard Credit Agreement (as amended) (together with its General Terms and Conditions, the “Equipment Financing Credit Agreement”) with KDB. In connection with the Equipment Financing Credit Agreement, on December 8, 2024, MSK also amended the
Kun-Pledge
Agreement (the “Equipment Pledge Agreement”) with KDB, originally executed on or about March 26, 2024, to increase the maximum secured amount and to expand the scope of collateral to include certain machinery and equipment owned by MSK, which are located in its fabrication facility located in Gumi, Korea (“Fab 3 machinery and equipment”).
The Equipment Financing Credit Agreement provides for loans for MSK’s capital expenditures (the “CAPEX Loans”) up to an aggregate of KRW 38,000,000,000 ($26,523 thousand based on the KRW/USD exchange rate of 1,432.7:1 as of December 16, 2024 as quoted by KEB Hana Bank), which will be funded directly to capital expenditure supply vendors by KDB upon the submission of a request form by MSK with the necessary evidence such as purchase agreement, invoice and other documentation, as applicable.
The CAPEX Loans will bear interest at a fixed rate quoted by the treasury bond market yield (a six-year Korea treasury bill rate). CAPEX Loans mature in ten years from the initial loan disbursement date (the “Maturity Date”), with an initial
two-year
(measured from the first loan disbursement date) interest-only payment period during which only interest is paid monthly, followed by eight years of amortizing payments where the principal is repaid in equal installments every three months and interest is paid monthly. The Equipment Financing Credit Agreement contains customary representations of MSK in connection with the execution of the agreement and with each borrowing of CAPEX Loans and customary terms and conditions for a secured equipment financing loan of this type in Korea. All obligations of MSK under the Equipment Financing Credit Agreement and CAPEX Loans are secured by certain Fab 3 machinery and equipment pursuant to the Equipment Pledge Agreement.
As of September 30, 2025, the aggregate principal amount outstanding under the CAPEX Loans was approximately $10,408 thousand, which bears a weighted average interest rate of 2.66% per annum and matures on June 26, 2035.

Diluted earnings (loss) per common share adjusts basic earnings (loss) per common share for the potentially dilutive impact of stock options and restricted stock units. As the Company has reported loss from continuing operations for the three and nine months ended September 30, 2025 and 2024, all potentially dilutive securities are antidilutive and accordingly not considered, therefore basic loss per common share equals diluted loss per common share.
The following outstanding instruments were excluded from the computation of diluted loss per common share, as they have an anti-dilutive effect on the calculation:

|  | Three Months Ended |  |  | Nine Months Ended |

Item 2. | Management’s Discussion and Analysis of Financial Condition and Results of Operations

The following discussion and analysis should be read in conjunction with the unaudited consolidated financial statements and the related notes included elsewhere in this Report.

Overview

We are a designer and manufacturer of analog and mixed-signal power semiconductor platform solutions for various applications, including industrial, automotive, communication, consumer and computing. We have a proven record with approximately 45 years of operating history, a portfolio of approximately 1,000 registered patents and pending applications and extensive engineering and manufacturing process expertise.

We develop and manufacture Power discrete products and develop Power integrated circuit (“IC”) products. Power discrete products include metal oxide semiconductor field effect transistors (“MOSFETs”) and insulated-gate bipolar transistors (“IGBTs”) for a range of devices, including televisions, smartphones, mobile phones, wearable devices, desktop personal computers (“PCs”), notebook PCs, tablet PCs, servers, other consumer electronics, as well as automotive and industrial applications such as power suppliers, e-bikes, solar inverters, LED lighting and motor drives. Power IC products include AC-DC/DC-DC converters, LED drivers, regulators, power management integrated circuits (“PMICs”) and level shifter for a range of devices, including televisions, wearable devices, notebooks, tablet PCs and others consumer electronics, as well as automotive applications.

In 2024, the Power IC business was operated by Magnachip Mixed-Signal, Ltd. (“MMS”), which later transferred the business to Magnachip Semiconductor, Ltd. (“MSK”) effective January 1, 2025, pursuant to an intercompany business transfer agreement executed between MMS and MSK. The transfer was based on the mutual understanding that consolidating the Power IC and Power Analog Solutions businesses under a single company would create a more effective framework for expanding and strengthening the Company’s business for Power products. We refer to the Power Analog Solutions and Power IC businesses collectively as the Power solutions business.

On March 7, 2025, our Board of Directors authorized a strategy to transition into a pure-play Power company, focusing its investments on the Power Analog Solutions and Power IC businesses to enhance profitability and maximize shareholder value. As part of this strategy, we explored all strategic options including a sale, merger, joint venture, licensing, and wind-down for its Display business (Display IC products). However, we were not able to consummate any transaction following several months of discussions with several interested parties on terms that our Board of Directors believed were in the best interests of the Company and our stockholders.

Accordingly, on April 6, 2025, our Board of Directors unanimously approved the plan to shut down our Display business (the “Discontinued Business”), including the liquidation of MMS, our indirect wholly owned subsidiary that operated the Discontinued Business. For additional information regarding the announcement of our plan to shut down display business, see the Company’s Current Report on Form 8-K filed on April 8, 2025. As a result of the Discontinued Business and the cessation of transitional Fab 3 foundry services, our results from continuing operations in future periods will consist solely of the Power solutions business.

Our wide variety of analog and mixed-signal power semiconductor products combined with our mature technology platform allow us to address multiple high-growth end markets and rapidly develop and introduce new products and services in response to market demands. Our design center in Korea and global manufacturing operations place us at the core of the global electronics device supply chain. We believe this enables us to quickly and efficiently respond to our customers’ needs, and allows us to better serve and capture additional demand from existing and new customers. Certain of our Power IC products are produced using an external foundry. Through a strategic cooperation with an external foundry, we manage to ensure outsourcing wafers at competitive price and produce quality products.

To maintain and increase our profitability, we must accurately forecast trends in demand for electronics devices that incorporate semiconductor products we produce. We must understand our customers’ needs as well as the likely end market trends and demand in the markets they serve. We must also invest in relevant research and development activities and purchase necessary materials on a timely basis to meet our customers’ demand while maintaining our target margins and cash flow.

The semiconductor markets in which we participate are highly competitive. The prices of our products tend to decrease regularly over their useful lives, and such price decreases can be significant as new generations of products are introduced by us or our competitors. We strive to offset the impact of declining selling prices for existing products through cost reductions and the introduction of new products that command selling prices above the average selling price of our existing products. In addition, we seek to manage our inventories and manufacturing capacity so as to mitigate the risk of losses from product obsolescence.

27

Demand for our products and services is driven by overall demand for industrial, automotive, communication, consumer and computing products and can be adversely affected by periods of weak consumer and enterprise spending or by market share losses by our customers. In order to mitigate the impact of market volatility on our business, we continually strive to diversify our portfolio of products, customers, and target applications. We also expect that new competitors will emerge in these markets that may place increased pressure on the pricing for our products and services. While we believe we are well positioned competitively to compete in these markets and against these new competitors as a result of our long operating history, existing manufacturing capacity and our worldwide customer base, if we are not effective in competing in these markets, our operating results may be adversely affected.

Net sales for our Power Analog Solutions and Power IC business are driven by design wins in which we are selected by an electronics original equipment manufacturer (“OEM”) or other potential customer to supply its demand for a particular product. A customer will often have more than one supplier designed into multi-source components for a particular product line. Once we have design wins and the products enter into mass production, we often specify the pricing of a particular product for a set period of time, with periodic discussions and renegotiations of pricing with our customers. In any given period, our net sales depend heavily upon the end-market demand for the goods in which our products are used, the inventory levels maintained by our customers and, in some cases, allocation of demand for components for a particular product among selected qualified suppliers.

In contrast to completely fabless semiconductor companies, our internal manufacturing capacity provides us with greater control over certain manufacturing costs and the ability to implement process and production improvements for our internally manufactured products, which can favorably impact gross profit margins. Our internal manufacturing capacity also allows for better control over delivery schedules, improved consistency over product quality and reliability and improved ability to protect intellectual property from misappropriation on these internally manufactured products. However, having internal manufacturing capacity exposes us to the risk of under-utilization of manufacturing capacity that results in lower gross profit margins, particularly during downturns in the semiconductor industry.

Our Power Analog Solutions and Power IC business requires investments in capital equipment. Analog and mixed-signal manufacturing facilities and processes are typically distinguished by the design and process implementation expertise rather than the use of the most advanced equipment. Many of these processes also tend to migrate more slowly to smaller geometries due to technological barriers and increased costs. For example, some of our products use high-voltage technology that requires larger geometries and that may not migrate to smaller geometries for several years, if at all. As a result, our manufacturing base and strategy do not require substantial investment in leading edge process equipment for those products, allowing us to utilize our facilities and equipment over an extended period of time with moderate required capital investments. In addition, we are less likely to experience significant industry overcapacity, which can cause product prices to decline significantly. In general, we seek to invest in manufacturing capacity that can be used for multiple high-value applications over an extended period of time. In addition, we outsource manufacturing of Power IC products which do require advanced technology and 8-inch wafer capacity. We believe this balanced capital investment strategy enables us to optimize our capital investments and facilitates more diversified product and service offerings.

By outsourcing manufacturing of Power IC products to an external foundry, we have been able to adapt dynamically to changing customer requirements and address growing markets without substantial capital investments by us. However, relying on an external foundry exposes us to the risk of being unable to secure manufacturing capacity, particularly during the global shortage of foundry services. Although we work to diversify the sourcing of external manufacturing, if these efforts are at any time unsuccessful, our ability to deliver products to our customers may be negatively impacted, which would adversely affect our relationship with customers and opportunities to secure new design-wins.

Our success going forward will depend upon our ability to adapt to future challenges such as the emergence of new competitors for our products and services or the consolidation of current competitors. Additionally, we must innovate to remain ahead of, or at least rapidly adapt to, technological breakthroughs that may lead to a significant change in the technology necessary to deliver our products and services. We believe that our established relationships and close collaboration with leading customers enhance our awareness of new product opportunities, market and technology trends and improve our ability to adapt and grow successfully.

Recent Developments

Shut-Down of Display business

On March 7, 2025, our Board of Directors authorized a strategy to transition to a pure-play Power company, focusing its investments on the Power Analog Solutions and Power IC businesses to enhance profitability and maximize shareholder value. As part of this strategy, we explored all strategic options including a sale, merger, joint venture, licensing, and wind-down for its Display business (Display IC products). However, we were not able to consummate a transaction following several months of discussions with several interested parties on terms that our Board of Directors believed were in the best interests of the Company and our stockholders.

Accordingly, on April 6, 2025, our Board of Directors unanimously approved the plan to shut down our Display business (the “Discontinued Business”) by the end of the second quarter of 2025, including the liquidation of MMS, our indirect wholly owned subsidiary that operated the Discontinued Business. For additional information regarding the announcement of our plan to shut down display business, see the Company’s Current Report on Form 8-K filed on April 8, 2025.

Although we shut down our Display business, we continue to provide limited support for remaining customer obligations including the sale of “end of life” (“EOL”) Display products, which is being conducted by MSK. We have retained a small team to continue to support customers with respect to EOL Display products. The sale of EOL Display products and the potential monetization of the intellectual property assets of the Discontinued Business are currently expected to generate cash inflow of approximately $20 million over a period of approximately 2 years from the second half of 2025, depending upon customer demand and monetization efforts of the Display intellectual property assets.

The total estimated cash cost of the liquidation is approximately $12 to $15 million, which is expected to be offset by the cash inflow that may be generated as described above. The one-time liquidation cost is expected to consist of statutory severance and other employee-related costs, contract termination charges and other associated costs. Of this estimated total cash cost, we paid $6.5 million of statutory severance and other employee-related costs in the second quarter of 2025. Further, we originally expected to pay certain contract termination charges in full along with the statutory severance and other employee-related costs, but negotiated with the respective vendors for those contract termination charges totaling $6.5 million to be paid over the duration of the remaining existing contract terms.

CAPEX Loans

On December 16, 2024, MSK executed a Standard Credit Agreement (as amended) (together with its General Terms and Conditions, the “Equipment Financing Credit Agreement”) with Korea Development Bank (“KDB”). In connection with the Equipment Financing Credit Agreement, on December 8, 2024, MSK amended the Kun-Pledge Agreement (the “Equipment Pledge Agreement”) with KDB, originally executed on or about March 26, 2024, to increase the maximum secured amount and to expand the scope of collateral to include certain machinery and equipment owned by MSK, which are located in its fabrication facility located in Gumi, Korea (“Fab 3 machinery and equipment”).

The Equipment Financing Credit Agreement provides for loans for MSK’s capital expenditures (the “CAPEX Loans”) up to an aggregate of KRW 38,000,000,000 ($26.5 million based on the KRW/USD exchange rate of 1,432.7:1 as of December 16, 2024 as quoted by KEB Hana Bank), which will be funded directly to capital expenditure supply vendors by KDB upon the submission of a request form by MSK with the necessary evidence such as purchase agreement, invoice and other documentation, as applicable.

The CAPEX Loans will bear interest at a fixed rate quoted by the treasury bond market yield (a six-year Korea treasury bill rate). CAPEX Loans mature in ten years from the initial loan disbursement date, with an initial two-year (measured from the first loan disbursement date) interest-only payment period during which only interest is paid monthly, followed by eight years of amortizing payments where the principal is repaid in equal installments every three months and interest is paid monthly. The Equipment Financing Credit Agreement contains customary representations of MSK in connection with the execution of the agreement and with each borrowing of CAPEX Loans and customary terms and conditions for a secured equipment financing loan of this type in Korea. All obligations of MSK under the Equipment Financing Credit Agreement and CAPEX Loans are secured by certain Fab 3 machinery and equipment pursuant to the Equipment Pledge Agreement.

As of September 30, 2025, the aggregate principal amount outstanding under the CAPEX Loans was approximately $10.4 million, which bears a weighted average interest rate of 2.66% per annum and matures on June 26, 2035.

Macroeconomic Industry Conditions

The semiconductor industry continues to face a number of macroeconomic challenges, including rising inflation, increased interest rates, supply chain disruptions, inventory corrections, shifting customer and end-user demand, fluctuations in currency rates, and geopolitical tensions, including without limitation ongoing conflicts involving Russia and Ukraine, sustained military action and conflicts in the Middle East, and trade conflicts or trade wars (especially those between the United States and China) including those arising directly or indirectly from tariffs recently imposed by the United States, any one or more of which may cause (if they have not already caused) volatility and unpredictability in the supply chain or market for semiconductor products and end-user demand. The length and severity of these macroeconomic events and their overall impact on our business, results of operations and financial condition remain uncertain.

Developments in Export Control Regulations

On October 7, 2022, the Bureau of Industry and Security (BIS) of the U.S. Department of Commerce published changes to U.S. export control regulations (U.S. Export Regulations), including new restrictions on Chinese entities’ ability to obtain advanced computing chips, develop and maintain supercomputers, and manufacture advanced semiconductors. Further, on October 12, 2022, a new rule went into effect requiring U.S. persons to obtain a license prior to engaging in certain activities that could “support” certain end-uses and end-users, including those related to weapons of mass destruction. Additionally, on October 21, 2022, BIS brought into effect a series of new Foreign Direct Product (FDP) rules and various new controls on advanced computing items, significantly expanding the scope of items that are subject to export control under the U.S. Export Regulations. More recently, on October 25, 2023, BIS published additional rules, which went into effect on November 17, 2023 to expand, clarify, and correct the rules published in October 2022. A further corrected and clarified version of these rules went into effect on April 4, 2024. On January 16, 2025, BIS published amendments and clarifications of the U.S. Export Regulations which further tightened controls of advanced computing items. On September 30, 2025, BIS published an “Affiliates Rule,” effective immediately, to expand end-user controls to cover certain affiliates of entities designated on BIS Entity List or Military End User List or designated on the Specially Designated Nationals and Blocked Persons (SDN) List administered by the U.S. Department of the Treasury, Office of Foreign Assets Control. Based on our understanding of the U.S. Export Regulations and related rules currently in effect, we expect to invest additional resources and efforts in the screening of prospects, customers, and end-users in order to comply with the new Affiliates Rule; while we do not anticipate that the rest of the rules will have a material impact on our current business, we will continue reviewing and assessing these rules and regulations and their potential impact on our business. Additional changes to the U.S. Export Regulations are expected, such as recently proposed rule changes that may expand restrictions on export transactions involving end users or end uses with military connections; but the scope or timing of such changes is uncertain. We will continue to monitor such developments, including potential additional trade restrictions, and other regulatory or policy changes by the U.S. and foreign governments.

Explanation and Reconciliation of Non-U.S. GAAP Measures

Adjusted EBITDA, Adjusted Operating Income (Loss) and Adjusted Net Income (Loss)

We use the terms Adjusted EBITDA, Adjusted Operating Income (Loss) and Adjusted Net Income (Loss) (including on a per share basis) in this Report. Adjusted EBITDA, as we define it, is a non-U.S. GAAP measure. We define Adjusted EBITDA for the periods indicated as EBITDA (as defined below), adjusted to exclude (i) equity-based compensation expense, (ii) foreign currency loss (gain), net, (iii) derivative valuation loss (gain), net and (iv) early termination and other charges. EBITDA for the periods indicated is defined as net income (loss) before interest income, interest expense, income tax expense (benefit), net and depreciation and amortization.

See the footnotes to the table below for further information regarding these items. We present Adjusted EBITDA as a supplemental measure of our performance because:

| • |  | we believe that Adjusted EBITDA, by eliminating the impact of a number of items that we do not consider to be indicative of our core ongoing operating performance, provides a more comparable measure of our operating performance from period-to-period and may be a better indicator of future performance;

| • |  | we believe that Adjusted EBITDA is commonly requested and used by securities analysts, investors and other interested parties in the evaluation of a company as an enterprise level performance measure that eliminates the effects of financing, income taxes and the accounting effects of capital spending, as well as other one time or recurring items described above; and

| • |  | we believe that Adjusted EBITDA is useful for investors, among other reasons, to assess a company’s period-to-period core operating performance and to understand and assess the manner in which management analyzes operating performance.

We use Adjusted EBITDA in a number of ways, including:

| • |  | for planning purposes, including the preparation of our annual operating budget;

| • |  | to evaluate the effectiveness of our enterprise level business strategies;

| • |  | in communications with our Board of Directors concerning our consolidated financial performance; and

| • |  | in certain of our compensation plans as a performance measure for determining incentive compensation payments.

We encourage you to evaluate each adjustment and the reasons we consider them appropriate. In evaluating Adjusted EBITDA, you should be aware that in the future we may incur expenses similar to the adjustments in this presentation. Adjusted EBITDA is not a measure defined in accordance with U.S. GAAP and should not be construed as an alternative to income (loss) from continuing operations or any other performance measure derived in accordance with U.S. GAAP, or as an alternative to cash flows from operating activities as a measure of liquidity. A reconciliation of loss to Adjusted EBITDA from continuing operations is as follows:

Adjustments: |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |
Equity-based compensation expense(a) |  |  | 0.1 |  |  |  | 2.0 |  |  |  | 1.6 |  |  |  | 3.5 |

Adjusted EBITDA from continuing operations |  | $ | (4.0 | ) |  | $ | (6.7 | ) |  | $ | 0.8 |  |  | $ | (4.6 | )

(a) | This adjustment eliminates the impact of non-cash equity-based compensation expenses. Although we expect to incur non-cash equity-based compensation expenses in the future, these expenses do not generally require cash settlement, and, therefore, are not used by us to assess the profitability of our operations. We believe that analysts and investors will find it helpful to review our operating performance without the effects of these non-cash expenses as supplemental information.

31

(b) | This adjustment mainly eliminates the impact of non-cash foreign currency translation associated with intercompany debt obligations and foreign currency denominated receivables and payables, as well as the cash impact of foreign currency transaction gains or losses on collection of such receivables and payment of such payables. Although we expect to incur foreign currency translation gains or losses in the future, we believe that analysts and investors will find it helpful to review our operating performance without the effects of these primarily non-cash gains or losses, which we cannot control. Additionally, we believe the isolation of this adjustment provides investors with enhanced comparability to prior and future periods of our operating performance results.

(c) | This adjustment eliminates the impact of gain or loss recognized in income on derivatives, which represents derivatives value changes excluded from the risk being hedged. We enter into derivative transactions to mitigate foreign exchange risks. As our derivative transactions are limited to a certain portion of our expected cash flows denominated in U.S. dollars, and we do not enter into derivative transactions for trading or speculative purposes, we do not believe that these charges or gains are indicative of our core operating performance.

(d) | For the three months ended September 30, 2025, this adjustment eliminates $2.6 million of termination-related charges in connection with the voluntary resignation program and $1.4 million of certain executive separation benefits. For the nine months ended September 30, 2025, this adjustment eliminates $2.6 million of termination-related charges, $1.7 million of certain executive separation benefits and $0.5 million of one-time employee incentives. As this adjustment meaningfully impacted our operating results and is not expected to represent an ongoing operating expense or income to us, we believe our operating performance results are more usefully compared if this adjustment is excluded.

Adjusted EBITDA has limitations as an analytical tool, and you should not consider it in isolation, or as a substitute for analysis of our results as reported under U.S. GAAP. Some of these limitations are:

| • |  | Adjusted EBITDA does not reflect our cash expenditures, or future requirements, for capital expenditures or contractual commitments;

| • |  | Adjusted EBITDA does not reflect changes in, or cash requirements for, our working capital needs;

| • |  | Adjusted EBITDA does not reflect the interest expense, or the cash requirements necessary to service interest or principal payments, on our debt;

| • |  | although depreciation and amortization are non-cash charges, the assets being depreciated and amortized will often need to be replaced in the future, and Adjusted EBITDA does not reflect any cash requirements for such replacements;

| • |  | Adjusted EBITDA does not consider the potentially dilutive impact of issuing equity-based compensation to our management team and employees;

| • |  | Adjusted EBITDA does not reflect the costs of holding certain assets and liabilities in foreign currencies; and

| • |  | other companies in our industry may calculate Adjusted EBITDA differently than we do, limiting its usefulness as a comparative measure.

Because of these limitations, Adjusted EBITDA should not be considered as a measure of discretionary cash available to us to invest in the growth of our business. We compensate for these limitations by relying primarily on our U.S. GAAP results and using Adjusted EBITDA only supplementally.

We present Adjusted Operating Income (Loss) as supplemental measures of our performance. We prepare Adjusted Operating Income (Loss) by adjusting operating income (loss) to eliminate the impact of equity-based compensation expenses and other items that may be either one time or recurring that we do not consider to be indicative of our core ongoing operating performance. We believe that Adjusted Operating Income (Loss) is useful to investors to provide a supplemental way to understand our underlying operating performance and allows investors to monitor and understand changes in our ability to generate income (loss) from ongoing business operations.

Adjusted Operating Income (Loss) is not a measure defined in accordance with U.S. GAAP and should not be construed as an alternative to operating income (loss) or any other performance measure derived in accordance with U.S. GAAP. We encourage you to evaluate each adjustment and the reasons we consider them appropriate. Other companies in our industry may calculate Adjusted Operating Income (Loss) differently than we do, limiting its usefulness as a comparative measure. In addition, in evaluating Adjusted Operating Income (Loss), you should be aware that in the future we may incur expenses similar to the adjustments in this presentation. We define Adjusted Operating Income (Loss) for the periods indicated as operating income (loss) adjusted to exclude (i) equity-based compensation expense and (ii) early termination and other charges.

The following table summarizes the adjustments to operating loss that we make in order to calculate Adjusted Operating Loss for the periods indicated:

|  | Three Months Ended September 30, 2025 |  |  | Nine Months Ended September 30, 2025 |  |  | Three Months Ended September 30, 2024 |  |  | Nine Months Ended September 30, 2024 |
|  | (Dollars in millions) |
Operating loss |  | $ | (11.5 | ) |  | $ | (23.4 | ) |  | $ | (4.5 | ) |  | $ | (19.1 | )
Adjustments: |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |
Equity-based compensation expense(a) |  |  | 0.1 |  |  |  | 2.0 |  |  |  | 1.6 |  |  |  | 3.5 |
Early termination and other charges(b) |  |  | 4.0 |  |  |  | 4.8 |  |  |  | — |  |  |  | — |
Adjusted Operating Loss |  | $ | (7.4 | ) |  | $ | (16.6 | ) |  | $ | (2.9 | ) |  | $ | (15.6 | )

(a) | This adjustment eliminates the impact of non-cash equity-based compensation expenses. Although we expect to incur non-cash equity-based compensation expenses in the future, these expenses do not generally require cash settlement, and, therefore, are not used by us to assess the profitability of our operations. We believe that analysts and investors will find it helpful to review our operating performance without the effects of these non-cash expenses as supplemental information.

(b) | For the three months ended September 30, 2025, this adjustment eliminates $2.6 million of termination-related charges in connection with the voluntary resignation program and $1.4 million of certain executive separation benefits. For the nine months ended September 30, 2025, this adjustment eliminates $2.6 million of termination-related charges, $1.7 million of certain executive separation benefits and $0.5 million of one-time employee incentives. As this adjustment meaningfully impacted our operating results and is not expected to represent an ongoing operating expense or income to us, we believe our operating performance results are more usefully compared if this adjustment is excluded.

33

We present Adjusted Net Income (Loss) (including on a per share basis) as a further supplemental measure of our performance. We prepare Adjusted Net Income (Loss) (including on a per share basis) by adjusting net income (loss) to eliminate the impact of a number of non-cash expenses and other items that may be either one time or recurring that we do not consider to be indicative of our core ongoing operating performance. We believe that Adjusted Net Income (Loss) (including on a per share basis) is particularly useful because it reflects the impact of our asset base and capital structure on our operating performance. We present Adjusted Net Income (Loss) (including on a per share basis) for a number of reasons, including:

| • |  | we use Adjusted Net Income (Loss) (including on a per share basis) in communications with our Board of Directors concerning our consolidated financial performance without the impact of non-cash expenses and the other items as we discussed below since we believe that it is a more consistent measure of our core operating results from period to period; and

| • |  | we believe that reporting Adjusted Net Income (Loss) (including on a per share basis) is useful to readers in evaluating our core operating results because it eliminates the effects of non-cash expenses as well as the other items we discuss below, such as foreign currency gains and losses, which are out of our control and can vary significantly from period to period.

Adjusted Net Income (Loss) (including on a per share basis) is not a measure defined in accordance with U.S. GAAP and should not be construed as an alternative to income (loss) from continuing operations or any other performance measure derived in accordance with U.S. GAAP, or as an alternative to cash flows from operating activities as a measure of liquidity. We encourage you to evaluate each adjustment and the reasons we consider them appropriate. Other companies in our industry may calculate Adjusted Net Income (Loss) (including on a per share basis) differently than we do, limiting its usefulness as a comparative measure. In addition, in evaluating Adjusted Net Income (Loss) (including on a per share basis), you should be aware that in the future we may incur expenses similar to the adjustments in this presentation. We define Adjusted Net Income (Loss) (including on a per share basis); for the periods indicated as net income (loss), adjusted to exclude (i) equity-based compensation expense, (ii) foreign currency loss (gain), net, (iii) derivative valuation loss (gain), net, (iv) early termination and other charges and (v) income tax effect on non-GAAP adjustments.

The following table summarizes the adjustments to loss from continuing operations that we make in order to calculate Adjusted Loss (including on a per share basis) from continuing operations for the periods indicated:

|  | Three Months Ended September 30, 2025 |  |  | Nine Months Ended September 30, 2025 |  |  | Three Months Ended September 30, 2024 |  |  | Nine Months Ended September 30, 2024 |

(a) | This adjustment eliminates the impact of non-cash equity-based compensation expenses. Although we expect to incur non-cash equity-based compensation expenses in the future, these expenses do not generally require cash settlement, and, therefore, are not used by us to assess the profitability of our operations. We believe that analysts and investors will find it helpful to review our operating performance without the effects of these non-cash expenses as supplemental information.

34

(b) | This adjustment mainly eliminates the impact of non-cash foreign currency translation associated with intercompany debt obligations and foreign currency denominated receivables and payables, as well as the cash impact of foreign currency transaction gains or losses on collection of such receivables and payment of such payables. Although we expect to incur foreign currency translation gains or losses in the future, we believe that analysts and investors will find it helpful to review our operating performance without the effects of these primarily non-cash gains or losses, which we cannot control. Additionally, we believe the isolation of this adjustment provides investors with enhanced comparability to prior and future periods of our operating performance results.

(c) | This adjustment eliminates the impact of gain or loss recognized in income on derivatives, which represents derivatives value changes excluded from the risk being hedged. We enter into derivative transactions to mitigate foreign exchange risks. As our derivative transactions are limited to a certain portion of our expected cash flows denominated in U.S. dollars, and we do not enter into derivative transactions for trading or speculative purposes, we do not believe that these charges or gains are indicative of our core operating performance.

(d) | For the three months ended September 30, 2025, this adjustment eliminates $2.6 million of termination-related charges in connection with the voluntary resignation program and $1.4 million of certain executive separation benefits. For the nine months ended September 30, 2025, this adjustment eliminates $2.6 million of termination-related charges, $1.7 million of certain executive separation benefits and $0.5 million of one-time employee incentives. As this adjustment meaningfully impacted our operating results and is not expected to represent an ongoing operating expense or income to us, we believe our operating performance results are more usefully compared if this adjustment is excluded.

(e) | For the three and nine months ended September 30, 2025 and 2024, income tax effect on non-GAAP adjustments were calculated by calculating the tax expense of each jurisdiction with or without the non-GAAP adjustments. For the three and nine months ended September 30, 2025, income tax effect on non-GAAP adjustments related to our Korean subsidiary was positive $1.8 million and negative $0.4 million, respectively. For the three and nine months ended September 30, 2024, income tax effect on non-GAAP adjustments related to our Korean subsidiary was negative $0.1 million and negative $1.3 million, respectively.

We believe that all adjustments to income (loss) from continuing operations used to calculate Adjusted Net Income (Loss) from continuing operations was applied consistently to the periods presented.

Adjusted Net Income (Loss) has limitations as an analytical tool, and you should not consider it in isolation, or as a substitute for analysis of our results as reported under U.S. GAAP. Some of these limitations are:

| • |  | Adjusted Net Income (Loss) does not reflect changes in, or cash requirements for, our working capital needs;

| • |  | Adjusted Net Income (Loss) does not consider the potentially dilutive impact of issuing equity-based compensation to our management team and employees;

| • |  | Adjusted Net Income (Loss) does not reflect the costs of holding certain assets and liabilities in foreign currencies; and

| • |  | Other companies in our industry may calculate Adjusted Net Income (Loss) differently than we do, limiting its usefulness as a comparative measure.

Because of these limitations, Adjusted Net Income (Loss) should not be considered as a measure of profitability of our business. We compensate for these limitations by relying primarily on our U.S. GAAP results and using Adjusted Net Income (Loss) only as a supplement.

Factors Affecting Our Results of Operations

Net Sales. We derive substantially all of our sales (net of sales returns and allowances) from our Power solutions business. Our product inventory is primarily located in Korea and is available for drop shipment globally. Outside of Korea, we maintain limited product inventory, and our sales representatives generally relay orders to our fabrication facility in Korea for fulfillment. We have strategically located our sales offices near concentrations of major customers. Our sales offices are located in Korea, Japan, Taiwan and Greater China. Our network of authorized agents and distributors is in the United States, Europe and the Asia Pacific region.

We recognize revenue when a customer obtains control of the product, which is generally upon product shipment, delivery at the customer’s location or upon customer acceptance, depending on the terms of the arrangement. For the nine months ended September 30, 2025 and 2024, we sold products to 173 and 147 customers, respectively, and our net sales to our ten largest customers represented 74.2% and 72.5% of our net sales – Power solutions business, respectively.

Gross Profit. Our overall gross profit generally fluctuates as a result of changes in overall sales volumes and in the average selling prices of our products and services. Other factors that influence our gross profit include changes in product mix, the introduction of new products and services and subsequent generations of existing products and services, shifts in the utilization of our manufacturing facility and the yields achieved by our manufacturing operations, changes in material, labor and other manufacturing costs including outsourced manufacturing expenses, and variation in depreciation expense.

Average Selling Prices (“ASP”). Average selling prices for our products tend to be highest at the time of introduction of new products which utilize the latest technology and tend to decrease over time as such products mature in the market and are replaced by next generation products. We strive to offset the impact of declining selling prices for existing products through our product development activities and by introducing new products that command selling prices above the average selling price of our existing products. In addition, we seek to manage our inventories and manufacturing capacity so as to preclude losses from product and productive capacity obsolescence.

Material Costs. Our material costs consist of costs of raw materials, such as silicon wafers, chemicals, gases and tape and packaging supplies. We use processes that require specialized raw materials, such as silicon wafers, that are generally available from a limited number of suppliers. If demand increases or supplies decrease, the costs of our raw materials could increase significantly.

Labor Costs. A significant portion of our employees are located in Korea. Under Korean labor laws, most employees and certain executive officers with one or more years of service are entitled to severance benefits upon the termination of their employment based on their length of service and rate of pay. As of September 30, 2025, 97% of our employees were eligible for severance benefits.

Depreciation Expense. We periodically evaluate the carrying values of long-lived assets, including property, plant and equipment and intangible assets, as well as the related depreciation periods. We depreciate our property, plant and equipment using the straight-line method over the estimated useful lives of our assets. Depreciation rates vary from 30-40 years on buildings to 3-12 years for certain equipment and assets. Our evaluation of carrying values is based on various analyses including cash flow and profitability projections. If our projections indicate that future undiscounted cash flows are not sufficient to recover the carrying value of the related long-lived assets, the carrying value of the assets is impaired and will be reduced, with the reduction charged to expense so that the carrying value is equal to fair value.

Selling Expenses. We sell our products worldwide through a direct sales force as well as a network of sales agents and representatives to OEMs, including major branded customers and contract manufacturers, and indirectly through distributors. Selling expenses consist primarily of the personnel costs for the members of our direct sales force, a network of sales representatives and other costs of distribution. Personnel costs include base salary, benefits and incentive compensation.

General and Administrative Expenses. General and administrative expenses consist of the costs of various corporate operations, including finance, legal, human resources and other administrative functions. These expenses primarily consist of payroll-related expenses, consulting and other professional fees and office facility-related expenses.

Research and Development. The rapid technological change and product obsolescence that characterize our industry require us to make continuous investments in research and development. Product development time frames vary but, in general, we incur research and development costs one to two years before generating sales from the associated new products. These expenses include personnel costs for members of our engineering workforce, cost of photomasks, silicon wafers and other non-recurring engineering charges related to product design. Additionally, we develop base line process technology through experimentation and through the design and use of characterization wafers that help achieve commercially feasible yields for new products. The majority of research and development expenses of our Power IC business are material and design-related costs for Power IC products. Power IC uses standard BCD process technologies which can be sourced from multiple foundries. The majority of research and development expenses of our Power discrete business are certain equipment, material and design-related costs for Power discrete products.

36

Impact of Foreign Currency Exchange Rates on Reported Results of Operations. Historically, a portion of our revenues and cost of sales and greater than the majority of our operating expenses have been denominated in non-U.S. currencies, principally the Korean won, and we expect that this will remain true in the future. Because we report our results of operations in U.S. dollars converted from our non-U.S. revenues and expenses based on monthly average exchange rates, changes in the exchange rate between the Korean won and the U.S. dollar could materially impact our reported results of operations and distort period to period comparisons. In particular, because of the difference in the amount of our consolidated revenues and expenses that are in U.S. dollars relative to Korean won, depreciation in the U.S. dollar relative to the Korean won could result in a material increase in reported costs relative to revenues, and therefore could cause our profit margins and operating income to appear to decline materially, particularly relative to prior periods. The converse is true if the U.S. dollar were to appreciate relative to the Korean won. Moreover, our foreign currency gain or loss would be affected by changes in the exchange rate between the Korean won and the U.S. dollar as a substantial portion of non-cash translation gain or loss is associated with the intercompany long-term loans to one of our Korean subsidiaries, Magnachip Semiconductor, Ltd. or MSK, which is denominated in U.S. dollars. As of September 30, 2025, the outstanding intercompany loan balance including accrued interest between MSK and our Dutch subsidiary was $244.7 million. As a result of such foreign currency exchange rate fluctuations, it could be more difficult to detect underlying trends in our business and results of operations. In addition, to the extent that fluctuations in currency exchange rates cause our results of operations to differ from our expectations or the expectations of our investors, the trading price of our stock could be adversely affected.

From time to time, we may engage in exchange rate hedging activities in an effort to mitigate the impact of exchange rate fluctuations. Our Korean subsidiary, Magnachip Semiconductor, Ltd., enters into foreign currency zero cost collar contracts in order to mitigate a portion of the impact of U.S. dollar-Korean won exchange rate fluctuations on our operating results. Obligations under these foreign currency zero cost collar contracts must be cash collateralized if our exposure exceeds certain specified thresholds. These zero cost collar contracts may be terminated by a counterparty in a number of circumstances, including if our total cash and cash equivalents is less than $30.0 million at the end of a fiscal quarter unless a waiver is obtained from the counterparty. We cannot assure that any hedging technique we implement will be effective. If our hedging activities are not effective, changes in currency exchange rates may have a more significant impact on our results of operations.

Foreign Currency Gain or Loss. Foreign currency translation gains or losses on transactions by us or our subsidiaries in a currency other than our or our subsidiaries’ functional currency are included in foreign currency gain (loss), net in our consolidated statements of operations. A substantial portion of this net foreign currency gain or loss relates to non-cash translation gain or loss related to the principal balance of intercompany balances at our Korean subsidiary, Magnachip Semiconductor, Ltd., that are denominated in U.S. dollars. This gain or loss results from fluctuations in the exchange rate between the Korean won and U.S. dollar.

Income Taxes. We record our income taxes in each of the tax jurisdictions in which we operate. This process involves using an asset and liability approach whereby deferred tax assets and liabilities are recorded for differences in the financial reporting bases and tax basis of our assets and liabilities. We exercise significant management judgment in determining our provision for income taxes, deferred tax assets and liabilities. We assess whether it is more likely than not that the deferred tax assets existing at the period-end will be realized in future periods. In such assessment, we consider all available positive and negative evidence, including scheduled reversals of deferred tax liabilities, projected future taxable income, tax planning strategies and recent results of operations. In the event we were to determine that we would be able to realize the deferred income tax assets in the future in excess of their net recorded amount, we would adjust the valuation allowance, which would reduce the provision for income taxes.

We are subject to income-or non-income-based tax examinations by tax authorities of the U.S., Korea and multiple other foreign jurisdictions for all open tax years. Significant estimates and judgments are required in determining our worldwide provision for income-or non-income based taxes. Some of these estimates are based on interpretations of existing tax laws or regulations. The ultimate amount of tax liability may be uncertain as a result.

Capital Expenditures. We primarily invest in manufacturing equipment, software design tools and other tangible assets mainly for fabrication facility maintenance, capacity expansion and technology improvement. Capacity expansions and technology improvements typically occur in anticipation of increases in demand. We typically pay for capital expenditures in partial installments with portions due on order, delivery and final acceptance. Our capital expenditures mainly include our payments for the purchase of property, plant and equipment.

Inventories. We monitor our inventory levels in light of product development changes and market expectations. We may be required to take additional charges for quantities in excess of demand, cost in excess of market value and product age. Our analysis may take into consideration historical usage, expected demand, anticipated sales price, new product development schedules, the effect new products might have on the sales of existing products, product age, customer design activity, customer concentration and other factors. These forecasts require us to estimate our ability to predict demand for current and future products and compare those estimates with our current inventory levels and inventory purchase commitments. Our forecasts for our inventory may differ from actual inventory use.

Operating Expenses

Selling, General and Administrative Expenses. Selling, general and administrative expenses were $8.3 million, or 18.1% of total revenues, for the three months ended September 30, 2025, compared to $9.5 million, or 17.2% of total revenues, for the three months ended September 30, 2024. The decrease of $1.2 million, or 12.7%, was primarily attributable to a decrease in employee compensation, mainly due to the forfeiture of equity-based compensation in connection with the separation of certain executive officers.

Research and Development Expenses. Research and development expenses were $7.8 million, or 16.9% of total revenues, for the three months ended September 30, 2025, compared to $6.5 million, or 11.7% of total revenues, for the three months ended September 30, 2024.

Early Termination and Other Charges. For the three months ended September 30, 2025, we recorded $2.6 million of termination-related charges in connection with the voluntary resignation program and $1.4 million of certain executive separation benefits.

Operating Loss

As a result of the foregoing, operating loss of $11.5 million was recorded for the three months ended September 30, 2025 compared to operating loss of $4.5 million for the three months ended September 30, 2024. As discussed above, the increase in operating loss of $7.1 million resulted primarily from a $4.0 million increase in early termination and other charges, a $3.0 million decrease in gross profit and a $1.3 million increase in research and development expenses, which was offset in part by a $1.2 million decrease in selling, general and administrative expenses.

Other Income (Expense)

Interest Income. Interest income was $1.3 million and $1.9 million for the three months ended September 30, 2025 and 2024, respectively.

Interest Expense. Interest expense was $0.5 million and $0.5 million for the three months ended September 30, 2025 and 2024, respectively.

Foreign Currency Gain (Loss), Net. Net foreign currency loss for the three months ended September 30, 2025 was $4.3 million compared to net foreign currency gain of $5.2 million for the three months ended September 30, 2024. The net foreign currency loss for the three months ended September 30, 2025 was due to the depreciation in value of the Korean won relative to the U.S. dollar during the period. The net foreign currency gain for the three months ended September 30, 2024 was due to the appreciation in value of the Korean won relative to the U.S. dollar during the period.

A substantial portion of our net foreign currency gain or loss is non-cash translation gain or loss associated with intercompany long-term loans to one of our Korean subsidiaries, which are denominated in U.S. dollars, and are affected by changes in the exchange rate between the Korean won and the U.S. dollar. As of September 30, 2025 and 2024, the outstanding intercompany loan balances, including accrued interest between our Korean subsidiary, Magnachip Semiconductor, Ltd., and our Dutch subsidiary, were $244.7 million and $259.7 million, respectively. Foreign currency translation gain or loss from intercompany balances were included in determining our consolidated net income (loss) since the intercompany balances were not considered long-term investments in nature because management intended to settle these intercompany balances at their respective maturity dates.

Income Tax Expense (Benefit), Net

Income tax benefit was $4.2 million for the three months ended September 30, 2025, which was primarily attributable to the estimated taxable loss in our Korean subsidiary for the respective period, including loss recognized in connection with the shutdown of the discontinued Display business during the second quarter of 2025.

Income tax expense was $6.1 million for the three months ended September 30, 2024, which was primarily related to the primary operating entity’s in-kind contribution of certain business lines made during the first quarter of 2024, as a result of its assessment of realizability of the deferred tax assets in the future.

Loss from Continuing Operations

Loss from continuing operations for the three months ended September 30, 2025 was $10.6 million compared to loss from continuing operations of $3.9 million for the three months ended September 30, 2024. The $6.7 million increase in loss from continuing operations was primarily attributable to a $9.5 million increase in net foreign currency loss and $7.1 million increase in operating loss, which was offset in part by a $10.3 million increases in income tax benefit.

Loss from Discontinued Operations, Net of Tax

Loss from discontinued operations, net of tax for the three months ended September 30, 2025 was $2.5 million, compared to loss from discontinued operations, net of tax of $5.7 million for the three months ended September 30, 2024. The $3.2 million improvement in loss from discontinued operations, net of tax primarily resulted from a $4.6 million improvement in operating loss, which was offset in part by a $1.7 million decrease in income tax benefit.

Net Loss

As a result of the foregoing, a net loss of $13.1 million was recorded for the three months ended September 30, 2025 compared to a net loss of $9.6 million for the three months ended September 30, 2024. As discussed above, the increase in net loss of $3.5 million primarily resulted from a $6.7 million increase in loss from continuing operations, which was offset by a $3.2 million improvement in loss from discontinued operations, net of tax.

Net sales – Power solutions business in Korea increased from $59.9 million for the nine months ended September 30, 2024 to $67.7 million for the nine months ended September 30, 2025, or by $7.8 million, or 13.1%, primarily due to an increased demand for power products such as low-voltage MOSFETs in communication applications, which was offset in part by a decreased revenue from the competitive pricing pressure on our older generation products in consumer applications. A higher demand for our Power IC products, primarily for LED televisions, also had a favorable impact on net sales.

Net sales – Power solutions business in Asia Pacific (other than Korea) decreased from $71.9 million for the nine months ended September 30, 2024 to $63.7 million for the nine months ended September 30, 2025, or by $8.1 million, or 11.3%, primarily due to a decreased revenue from the competitive pricing pressure on our older generation products in consumer and industrial applications, which was offset in part by a higher demand for low-voltage MOSFETs in communication applications.

Operating Expenses

Selling, General and Administrative Expenses. Selling, general and administrative expenses were $26.5 million, or 19.2% of total revenues, for the nine months ended September 30, 2025, compared to $28.3 million, or 19.5% of total revenues, for the nine months ended September 30, 2024. The decrease of $1.9 million, or 6.5%, was primarily attributable to a decrease in employee compensation, mainly due to the forfeiture of equity-based compensation in connection with the separation of certain executive officers, as well as a decrease in professional fees mainly comprised of legal and consulting fees.

Research and Development Expenses. Research and development expenses were $19.7 million, or 14.2% of total revenues, for the nine months ended September 30, 2025, compared to $18.5 million, or 12.7% of total revenues, for the nine months ended September 30, 2024. The increase of $1.2 million, or 6.7%, was primarily attributable to higher personnel costs resulting from the increased headcount of research and development staff and an increase in material costs for power products based on the timing of development activities.

Early Termination and Other Charges. For the nine months ended September 30, 2025, we recorded $2.6 million of termination-related charges in connection with the voluntary resignation program, $1.7 million of certain executive separation benefits and $0.5 million of one-time employee incentives.

Operating Loss

As a result of the foregoing, operating loss of $23.4 million was recorded for the nine months ended September 30, 2025 compared to operating loss of $19.1 million for the nine months ended September 30, 2024. As discussed above, the increase in operating loss of $4.3 million resulted primarily from a $4.8 million increase in early termination and other charges and a $1.2 million increase in research and development expenses, which was offset in part by a $1.9 million decrease in selling, general and administrative expenses.

44

Other Income (Expense)

Interest Income. Interest income was $4.1 million and $6.2 million for the nine months ended September 30, 2025 and 2024, respectively.

Interest Expense. Interest expense was $1.3 million and $1.1 million for the nine months ended September 30, 2025 and 2024, respectively.

Foreign Currency Gain (Loss), Net. Net foreign currency gain for the nine months ended September 30, 2025 was $6.1 million compared to net foreign currency loss of $3.4 million for the nine months ended September 30, 2024. The net foreign currency gain for the nine months ended September 30, 2025 was due to the appreciation in value of the Korean won relative to the U.S. dollar during the period. The net foreign currency loss for the nine months ended September 30, 2024 was due to the depreciation in value of the Korean won relative to the U.S. dollar during the period.

A substantial portion of our net foreign currency gain or loss is non-cash translation gain or loss associated with intercompany long-term loans to one of our Korean subsidiaries, which are denominated in U.S. dollars, and are affected by changes in the exchange rate between the Korean won and the U.S. dollar. As of September 30, 2025 and 2024, the outstanding intercompany loan balances, including accrued interest between our Korean subsidiary, Magnachip Semiconductor, Ltd., and our Dutch subsidiary, were $244.7 million and $259.7 million, respectively. Foreign currency translation gain or loss from intercompany balances were included in determining our consolidated net income (loss) since the intercompany balances were not considered long-term investments in nature because management intended to settle these intercompany balances at their respective maturity dates.

Income Tax Expense (Benefit), Net

Income tax benefit was $8.7 million for the nine months ended September 30, 2025, which was primarily attributable to the estimated taxable loss in our Korean subsidiary for the respective period, including loss recognized in connection with the shutdown of the discontinued Display business during the second quarter of 2025.

Income tax expense was $2.3 million for the nine months ended September 30, 2024, which was primarily related to a decrease in tax benefits from pre-tax loss of one of our operating entities in Korea and a valuation allowance established against the deferred tax assets of the other operating entity in Korea, as a result of its assessment of realizability of the deferred tax assets in the future.

Loss from Continuing Operations

Loss from continuing operations for the nine months ended September 30, 2025 was $5.5 million compared to loss from continuing operations of $19.6 million for the nine months ended September 30, 2024. The $14.2 million improvement in results from continuing operations was primarily attributable to a $9.5 million improvement in net foreign currency gain or loss, and an $11.0 million increase in income tax benefit, which was offset in part by a $4.3 million increase in operating loss and a $2.1 million decrease in interest income.

Loss from Discontinued Operations, Net of Tax

Loss from discontinued operations, net of tax for the nine months ended September 30, 2025 was $16.2 million, compared to loss from discontinued operations, net of tax of $18.4 million for the nine months ended September 30, 2024. The $2.2 million improvement in loss from discontinued operations, net of tax primarily resulted from a $3.0 million improvement in operating loss, which was offset in part by a $0.7 million increase in income tax expense.

Net Loss

As a result of the foregoing, a net loss of $21.6 million was recorded for the nine months ended September 30, 2025 compared to a net loss of $38.0 million for the nine months ended September 30, 2024. As discussed above, the improvement in net loss of $16.4 million primarily resulted from a $14.2 million decrease in loss from continuing operations and a $2.2 million decrease in loss from discontinued operations, net of tax.

Liquidity and Capital Resources

Our principal capital requirements are to fund sales and marketing, invest in research and development and capital equipment, to make debt service payments and to fund working capital needs. We calculate working capital as current assets less current liabilities.

Our principal sources of liquidity are our cash, cash equivalents, cash flows from operations and financing activities. Our ability to manage cash and cash equivalents may be limited, as our primary cash flows are dictated by the terms of our sales and supply agreements, contractual obligations, debt instruments and legal and regulatory requirements. From time to time, we may sell accounts receivable to third parties under factoring agreements or engage in accounts receivable discounting to facilitate the collection of cash. In addition, from time to time, we may make payments to our vendors on extended terms with their consent. As of September 30, 2025, we did not have any accounts payable on extended terms or payment deferment with our vendors.

As of June 29, 2018, our Korean subsidiary, Magnachip Semiconductor, Ltd. (“MSK”), entered into an arrangement whereby it (i) acquired a water treatment facility from SK hynix for $4.2 million to support our fabrication facility in Gumi, Korea, and (ii) subsequently sold the water treatment facility for $4.2 million to a third party management company that we engaged to run the facility for a 10-year term beginning July 1, 2018. As of September 30, 2025, the outstanding obligation of this arrangement is approximately $11.4 million for remaining service term through 2028.

On March 26, 2024, MSK executed a Standard Credit Agreement (together with its General Terms and Conditions, the “Loan Agreement”) with Korea Development Bank (“KDB”). The Loan Agreement provides for a working capital term loan (the “Term Loan”) of KRW 40,000,000,000 (approximately $28.5 million based on the KRW/USD exchange rate of 1,402.2:1 as of September 30, 2025 as quoted by KEB Hana Bank). The Term Loan requires monthly interest-only payments and matures on March 26, 2027, at which time the full principal balance will be due and payable.

On June 26, 2025, under its existing Equipment Financing Credit Agreement with KDB, MSK entered into a CAPEX Loan of KRW 9,520,000,000 (approximately $6.8 million based on the KRW/USD exchange rate of 1,402.2:1 as of September 30, 2025 as quoted by KEB Hana Bank). On September 26, 2025, MSK additionally entered into a CAPEX Loan of KRW 5,075,000,000 (approximately $3.6 million based on the KRW/USD exchange rate of 1,402.2:1 as of September 30, 2025 as quoted by KEB Hana Bank). The CAPEX Loan requires monthly interest-only payments, with principal repayments deferred for an initial two-year period and amortized over the subsequent eight years, and matures on June 26, 2035.

As of September 30, 2025, cash and cash equivalents held by MSK were $99.2 million, which represents 92% of our total cash and cash equivalents on a consolidated basis. We currently believe that we will have sufficient cash reserves from cash on hand and expected cash from operations to fund our operations as well as capital expenditures for the next 12 months and the foreseeable future.

Working Capital

Our working capital balance as of September 30, 2025 was $151.7 million compared to $173.0 million as of December 31, 2024. The decrease in working capital balance was mainly attributable to a $30.6 million decrease in cash and cash equivalents resulted primarily from a $6.5 million of severance and other employee-related costs in connection with the liquidation of MMS, and continued execution of capital expenditures and stock repurchase program.

Cash Flows from Operating Activities

Cash outflow used in operating activities totaled $29.6 million for the nine months ended September 30, 2025, compared to $18.0 million of cash outflow used in operating activities for the nine months ended September 30, 2024. The net operating cash outflow for the nine months ended September 30, 2025 reflects our net loss of $21.6 million, as adjusted favorably by $17.8 million, which mainly consisted of depreciation and amortization, provision for severance benefits, provision for inventory reserves, net foreign currency gain and stock-based compensation, and net unfavorable impact of $25.8 million from changes in operating assets and liabilities.

Cash Flows from Investing Activities

Cash outflow used in investing activities totaled $13.0 million for the nine months ended September 30, 2025, compared to $35.4 million of cash outflow used in investing activities for the nine months ended September 30, 2024. The $22.4 million decrease in cash outflow was primarily attributable to a $30.0 million of investment in short-term financial instruments in 2024, a $2.2 million of net decrease in hedge collateral and $4.9 million decrease in net payment of guarantee deposits, which was offset in part by a $15.6 million increase in purchase of property, plant and equipment.

46

Cash Flows from Financing Activities

Cash inflow provided by financing activities totaled $5.8 million for the nine months ended September 30, 2025, compared to $20.1 million of cash inflow provided by financing activities for the nine months ended September 30, 2024. The financing cash inflow for the nine months ended September 30, 2025 was primarily attributable to the $10.6 million of proceeds received from the CAPEX Loans with KDB, which was offset in part by a payment of $3.7 million for the repurchases of our common stock pursuant to our stock repurchase program and a payment of $0.6 million for the repurchase of our common stock to satisfy tax withholding obligations in connection with the vesting of restricted stock units. The financing cash inflow for the nine months ended September 30, 2024 was primarily attributable to the $30.1 million of proceeds received from the Term Loan with KDB, which was offset in part by a payment of $8.9 million for the repurchases of our common stock pursuant to our stock repurchase program and a payment of $0.6 million for the repurchase of our common stock to satisfy tax withholding obligations in connection with the vesting of restricted stock units.

For additional cash flow information associated with our discontinued operation, please see “Item 1. Interim Consolidated Financial Statements – Notes to Consolidated Financial Statements – Note 2 – Discontinued Operations” included elsewhere in this Report.

Capital Expenditures

We routinely make capital expenditures for fabrication facility maintenance, enhancement of our existing facility and reinforcement of our global research and development capability. For the nine months ended September 30, 2025, capital expenditures for property, plant and equipment were $19.7 million, a $15.6 million, or 372.8%, increase from $4.2 million for the nine months ended September 30, 2024.

Looking ahead, we expect the capital expenditures for the year ending December 31, 2025, to be in the range of $29 to $30 million, of which $19.7 million was incurred through September 30, 2025. The $29 to $30 million range includes approximately $20 million planned for investments to upgrade our fabrication facility located in Gumi, Korea. These upgrade capital expenditures will be partially funded through the $26.5 million Equipment Financing Credit Agreement, which is specifically designated for equipment purchases or upgrades in our Gumi fabrication facility. Of the $19.7 million incurred in 2025, $13.6 million was related to investments to upgrade our Gumi fabrication facility, of which $10.6 million was funded through the Equipment Financing Credit Agreement. These investments to upgrade the Gumi fabrication facility are expected to drive development of new generation products, and upgrade new tools to optimize product mix and improve gross profit margin in the future.

Critical Accounting Policies and Estimates

Preparing financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities as of the date of the financial statements, the reported amounts of revenues and expenses during the reporting periods and the related disclosures in our consolidated financial statements and accompanying notes.

We believe that our significant accounting policies, which are described further in Note 1 to our consolidated financial statements in our Annual Report on Form 10-K for our fiscal year ended December 31, 2024, or our 2024 Form 10-K, are critical due to the fact that they involve a high degree of judgment and estimates about the effects of matters that are inherently uncertain. We base these estimates and judgments on historical experience, knowledge of current conditions and other assumptions and information that we believe to be reasonable. Estimates and assumptions about future events and their effects cannot be determined with certainty. Accordingly, these estimates may change as new events occur, as more experience is acquired, as additional information is obtained and as the business environment in which we operate changes.

A description of our critical accounting policies that involve significant management judgement appears in our 2024 Form 10-K, under “Management’s Discussion and Analysis of Financial Conditions and Reports of Operations—Critical Accounting Policies and Estimates.” There have been no other material changes to our critical accounting policies and estimates as compared to our critical accounting policies and estimates included in our 2024 Form 10-K.
