Basis of Presentation

The condensed consolidated financial data at December 31, 2024 are derived from audited financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2024 filed with the Securities and Exchange Commission (“SEC”) on February 14, 2025 (“Form 10-K”). The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with United States Generally Accepted Accounting Principles (“GAAP”) for interim financial information and with the instructions to Form 10-Q. They do not include all information and footnotes necessary for a fair presentation of financial position, operating results, and cash flows in conformity with GAAP for complete financial statements. These condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and related notes contained in our Form 10-K. All significant intercompany balances and transactions have been eliminated in consolidation. In the opinion of management, all adjustments (consisting of normal recurring adjustments and accruals) considered necessary for a fair presentation of the operating results for the period presented have been included in the interim period. Operating results for the three months ended March 31, 2025 are not necessarily indicative of the results that may be expected for other interim periods or the year ending December 31, 2025.

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from these estimates. As permitted under GAAP, interim accounting for certain expenses, including income taxes, are based on full year forecasts. For interim financial reporting purposes, income taxes are recorded based upon estimated annual effective income tax rates taking into consideration discrete items occurring in a quarter.

Dollar amounts and share amounts are presented in thousands, except per share amounts, unless otherwise noted. Certain prior year’s balances may have been reclassified to conform to the current condensed consolidated financial statement presentation.

Recently Issued Accounting Pronouncements

In November 2024, the Financial Accounting Standards Board issued Accounting Standards Update 2024-03, Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures (Subtopic 220-40). The amendments in this update require that at each interim and annual reporting period an entity disclose:

•

The amounts of purchases of inventory, employee compensation, depreciation, intangible asset amortization, and depreciation, depletion, and amortization recognized as part of oil and gas-producing activities (or other amounts of depletion expense) included in each relevant expense caption. A relevant expense caption is an expense caption presented on the face of the income statement within continuing operations that contains any of the expense categories listed above;

•

Companies are also required to include certain amounts that are already required to be disclosed under current generally accepted accounting principles in the same disclosure as the other disaggregation requirements;

•

Disclose a qualitative description of the amounts remaining in relevant expense captions that are not separately disaggregated quantitatively; and

•

Disclose the total amount of selling expenses and, in annual reporting periods, an entity’s definition of selling expenses.

The amendments in this update are effective for annual reporting periods beginning after December 15, 2026, and interim reporting periods beginning after December 15, 2027. Early adoption is permitted.

NOTE 2 – Earnings per Share

Earnings per share (“EPS”) is calculated by dividing net income attributable to common stockholders by the weighted-average number of shares of Common Stock outstanding during the period. Diluted EPS is calculated similarly but includes potential dilution from the exercise of stock options and stock awards, except when the effect would be anti-dilutive. No dividends were paid on our Common Stock in any of the periods presented in this report.

The table below sets forth the reconciliation between net income and the weighted average shares outstanding used for calculating basic and diluted EPS:

NOTE 5 – Income Tax Provision

The table below sets forth information related to our income tax expense:


	Three Months Ended
	March 31,
	2025			2024
Domestic pre-tax income (loss)	$	14,623		$	(1,574	)
Foreign pre-tax (loss) income	$	(17,390	)	$	20,380

Impact of tax holidays on tax expense	$	(174	)	$	(93	)
Earnings per share impact of tax holidays:
Basic	$	-		$	-
Diluted	$	-		$	-

The decrease in effective tax rate for the three months ended March 31, 2025, when compared to the three months ended March 31, 2024, is primarily due to the change in pre-tax earnings during the comparable periods, including the geographical mix of pre-tax income and loss across tax jurisdictions.

Our undistributed foreign earnings continue to be indefinitely reinvested in foreign operations, with limited exceptions related to certain earnings of European and Asian subsidiaries. Any future distributions of foreign earnings will not be subject to additional U.S. income tax but may be subject to non-U.S. withholding taxes.

We file income tax returns in the U.S. federal jurisdiction and in various state and foreign jurisdictions. We are no longer subject to U.S. federal income tax examinations by tax authorities for tax years before 2021. We are no longer subject to China income tax examinations by tax authorities for tax years before 2013. With respect to state and local jurisdictions and countries outside of the U.S. (other than China), with limited exceptions, the Company is no longer subject to income tax audits for years before 2018. Although the outcome of tax audits is always uncertain, the Company believes that adequate amounts of tax, interest and penalties, if any, have been provided for in the Company’s reserve for any adjustments that may result from currently pending tax audits. The Company recognizes accrued interest and penalties related to unrecognized tax benefits in interest expense. As of March 31, 2025, the gross amount of unrecognized tax benefits was approximately $44.8 million.

Several jurisdictions in which we operate have either enacted, or announced plans to enact, legislation consistent with the Organization for Economic Co-operation and Development Global Anti-Base Erosion Model Rules ("Pillar Two") which introduced a global minimum effective tax rate of 15% applied on a jurisdiction-by-jurisdiction basis. We have analyzed enacted legislation and do not anticipate that it will have a material impact on our effective tax rate for 2025; however, we continue to monitor future tax legislative changes in the jurisdictions in which we operate in order to evaluate the impacts to the consolidated financial statements.

It is reasonably possible that the amount of the unrecognized benefit with respect to certain of the Company’s unrecognized tax positions will significantly increase or decrease within the next 12 months. At this time, an estimate of the range of the reasonably possible outcomes cannot be made.

NOTE 6 – Share-Based Compensation

The table below sets forth information related to our share-based compensation expense:


	Three Months Ended
	March 31,
	2025		2024
Cost of goods sold	$	554	$	450
Selling, general, and administrative		4,616		3,354
Research and development		1,216		1,268
Total share-based compensation expense	$	6,386	$	5,072

Share Grants. Share grants consist of restricted stock awards, restricted stock units (“RSUs”) and performance stock units (“PSUs”). Restricted stock awards and RSUs generally vest in equal annual installments over a four-year period and are measured based

-13-

on the fair market value of the underlying stock on the date of grant. Compensation expense is recognized on a straight-line basis over the requisite four-year service period. All new grants are awarded under the Company’s 2022 Equity Incentive Plan.

PSUs are measured based on the fair market value of the underlying stock on the date of grant, and compensation expense is recognized over the three-year performance period, with adjustments made to the expense to recognize the probable payout percentage.

As of March 31, 2025, total unrecognized share-based compensation expense related to share grants was approximately $53.9 million, before income taxes, and is expected to be recognized over a weighted average period of approximately 2.3 years.

NOTE 7 – Enterprise-Wide Segment Information and Net Sales

Segment Reporting. For financial reporting purposes, we operate in a single segment, standard semiconductor products, through our various manufacturing and distribution facilities. One segment reflects how our chief operating decision maker, which is our chief executive officer, allocates resources and measures results. We aggregate our products because the products are similar and have similar economic characteristics, use similar production processes and share similar customer type. Our primary operations include operations in Asia, the Americas, and Europe. During the three months ended March 31, 2025, two customers accounted for approximately $39.0 million and $33.6 million, or 11.8% and 10.1%, respectively, of our net sales and one customer accounted for approximately 14.1% of our outstanding accounts receivable at March 31, 2025. During the three months ended March 31, 2024, one customer accounted for approximately $42.7 million or 14.2% of our net sales and one customer accounted for approximately 17.3% of our outstanding accounts receivable at March 31, 2024. All customers that accounted for 10% or more of our net sales during any period presented in this Quarterly Report on Form 10-Q are broad-based global distributors that sell to thousands of different end users.

Disaggregation of Net Sales. We disaggregate net sales with customers into direct sales to end customers and distribution sales to distributors (“Distributors”) and by geographic area. Direct sales customers consist of those customers using our product in their manufacturing process, and Distributors are those customers who resell our products to third parties. We deliver our products to customers around the world for use in the industrial, automotive, computing, consumer, and communications markets. Further, most of our contracts are fixed-price arrangements, and are short term in nature, ranging from days to several months. The tables below set forth net sales based on the location of the subsidiary producing the net sale:

Short-term debt

Our Asia subsidiaries maintain credit facilities with several financial institutions through our foreign entities worldwide totaling $125.4 million. Other than two Taiwanese credit facilities that are collateralized by assets, our foreign credit lines are unsecured, uncommitted and contain no restrictive covenants. These credit facilities bear interest at the Taipei Interbank Offered Rate (or similar indices) plus a specified margin. Interest payments are due monthly on outstanding amounts under the credit lines. The unused and available credit under the various facilities as of March 31, 2025, was approximately $93.9 million, net of $31.0 million advanced under our foreign credit lines and $0.4 million credit used for import and export guarantee.

Long-term debt

The Company maintains a long-term credit facility (“Credit Agreement”). The Credit Agreement consists of a Revolving Credit Facility in the amount of $225.0 million, including a swing line sublimit equal to the lesser of $50.0 million and the Revolving Credit Facility, a letter of credit sublimit equal to the lesser of $100.0 million and the Revolving Credit Facility, and an alternative currency sublimit equal to the lesser of $40.0 million and the Revolving Credit Facility. The Company has the option to increase the Credit Facility and/or incur Incremental Term Loans in an aggregate principal amount of up to $350.0 million. There was no outstanding balance at March 31, 2025.

NOTE 9 – Commitments and Contingencies

Purchase Commitments. We have entered into non-cancelable purchase contracts for capital expenditures, primarily for manufacturing equipment, for approximately $26.9 million at March 31, 2025. As of March 31, 2025, we also had a commitment to purchase approximately $79.4 million of wafers to be used in our manufacturing process. These wafer purchases are scheduled to occur through 2031.

Defined Benefit Plan. We have a contributory defined benefit plan that covers certain employees in the United Kingdom. As of March 31, 2025, the underfunded liability for this defined benefit plan was approximately $4.8 million. We have agreed to a revised schedule of contributions of GBP 2.0 million (approximately $2.6 million based on a GBP: USD exchange rate of 1:1.3) to be paid annually with effect from January 1, 2023 to address the deficit revealed by the valuation (with the annual payments to be made by December 31, 2023 through December 31, 2028). A final payment of GBP 1.5 million (approximately $2.0 million based on a GBP: USD rate of 1:1.3) will be made by December 31, 2029.

Contingencies. From time to time, we are involved in various legal proceedings that arise in the normal course of business. While we intend to defend any lawsuit vigorously, we presently believe that the ultimate outcome of any pending legal proceeding will not have any material adverse effect on our consolidated financial position, cash flows, or operating results. However, litigation is subject to inherent uncertainties, and unfavorable rulings could occur. An unfavorable ruling could include monetary damages, which could impact our business and operating results for the period in which the ruling occurs and future periods. Based on available information available, we evaluate the likelihood of potential outcomes of all pending disputes. We record an appropriate liability when the amount of any liability associated with a pending dispute is deemed probable and reasonably estimable. In addition, we do not accrue estimated legal fees and other directly related costs as they are expensed as incurred. The Company is not currently a party to any pending litigation that we consider material.

NOTE 10 – Derivative Financial Instruments

We use derivative instruments to manage risks related to foreign currencies, interest rates, and the net investment risk in our foreign subsidiaries. Our objectives for holding derivatives include reducing, eliminating, and efficiently managing the economic impact of these exposures as effectively as possible. Our derivative programs include strategies that both qualify and do not qualify for hedge accounting treatment.

Hedges of Foreign Currency Risk. We are exposed to fluctuations in various foreign currencies against our different functional currencies. We use foreign currency forward agreements to manage this exposure. As of March 31, 2025 and December 31, 2024, we had $255.8 million and $380.9 million, respectively, of outstanding foreign currency forward agreements that are intended to preserve the economic value of foreign currency denominated monetary assets and liabilities; these instruments are not designated for hedge accounting treatment in accordance with Accounting Standards Codification (“ASC”) No. 815.

Hedges of Interest Rate and Net Investment Risk. The Company’s objectives in using interest rate derivatives are to add stability to interest expense and to manage its exposure to interest rate movements. To accomplish these objectives, the Company primarily uses interest rate swaps, including interest rate collars, as part of its interest rate risk management strategy. Interest rate swaps designated as cash flow hedges involve the receipt of variable amounts from a counterparty in exchange for the Company making fixed-rate payments over the life of the agreements without exchange of the underlying notional amount. The Company makes use of cross-currency swaps and foreign-currency forward contracts to decrease the foreign exchange risk inherent in the Company’s investment in some of its foreign subsidiaries.

The table below sets forth the fair value of the Company’s derivative financial instruments as well as their classification on our condensed consolidated balance sheets as of March 31, 2025 and December 31, 2024:

NOTE 12 – Employee Benefit Plans

We maintain a Non-Qualified Deferred Compensation Plan (the “Deferred Compensation Plan”) for executive officers, key employees, and members of the Board of Directors. The Deferred Compensation Plan allows eligible participants to defer the receipt of eligible compensation, including equity awards, until designated future dates. We offset our obligations under the Deferred Compensation Plan primarily by investing in the actual underlying investments. At March 31, 2025 and December 31, 2024, these investments totaled approximately $17.2 million.

NOTE 13 – Related Parties

We conduct business with the following related parties: Keylink International (B.V.I.) Inc. and its subsidiaries and affiliates (“Keylink”), Nuvoton Technology Corporation (“Nuvoton”), Jiyuan Crystal Photoelectric Frequency Technology Ltd. (“JCP”), and Atlas Magnetics, Co. (“Atlas”).

Keylink is a 5% joint venture partner in our Shanghai assembly and test facilities. We sell products to, and purchase inventory from, companies owned by Keylink. In addition, our subsidiaries in China lease their manufacturing facilities in Shanghai from, and subcontract a portion of our manufacturing process (metal plating and environmental services) to, Keylink. We also pay a consulting fee to Keylink.

Warren Chen, a member of the Company’s board of directors, serves as a member of the Nuvoton board of directors. We purchase wafers from Nuvoton for use in our production process. We have an agreement to purchase approximately $8.7 million of wafers from Nuvoton that ends in the second quarter of 2027. We consider our relationship with Nuvoton to be mutually beneficial, and plan to continue our strategic alliance with Nuvoton.

JCP is a frequency control product manufacturing company from which we purchase material and in which we have made an equity investment that we account for using the equity method of accounting.

Atlas is an early stage privately held fabless wafer design company in which the Company holds a majority interest. The Company determined that Atlas is a variable interest entity (“VIE”), and the Company does not have the power to direct the activities that most significantly impact Atlas. The Company has therefore determined that the Company is not the primary beneficiary. Consequently, we do not consolidate the assets and liabilities of Atlas in the Company’s financial statements. For additional information related to Atlas see Note 14 - Equity Investments - Unconsolidated VIE, below.

The tables below set forth the revenues, expenses, accounts receivable and accounts payable with our related parties:

NOTE 14 - Equity Investments

The Company maintains equity investments in companies which are accounted for under the measurement alternative described in ASC 321-10-35-2 for equity securities that lack readily determinable fair values. As of March 31, 2025, the Company had $49.6 million of investments accounted for under the measurement alternative. During the three months ended March 31, 2025, the Company recorded a $5.8 million non-cash impairment charge related to the decrease in value of a previously made equity investment.

Unconsolidated VIE

During July 2021, the Company acquired an interest in Atlas, an early stage privately held fabless wafer design company located in the western United States. The Company’s initial investment in July 2021 was $10.0 million of preferred stock and a $5.0 million convertible promissory note. In April 2023, the Company acquired an additional interest in Atlas by purchasing $13.9 million of preferred stock. The primary purpose for providing the additional investment in Atlas was for continued access to developing technology with potential future benefit to the Company. As part of the April 2023 agreement, the Company’s previously held convertible note converted to $5.2 million of preferred stock and at March 31, 2025, the Company owned more than 50% of Atlas. The Company determined that Atlas is a VIE and a related party. While the Company does own more than 50% of Atlas, according to the voting agreement governing the transaction, the Company does not have the power to control the board of directors or direct the activities that most significantly impact Atlas, including:

• The hiring and firing of officers (i.e., CEO, CFO, etc.) – The hiring and firing of personnel responsible for making the key daily decisions and implementing the strategic operating direction will determine the success the Company has in their initiatives, thereby affecting the economic performance;

• Determining the business plan and budget, including incurring additional indebtedness or issuing additional equity interests – As Atlas is thinly capitalized, the decisions around when and how to obtain cash will influence whether AM can continue operating; and

• Determining the strategic operating direction of Atlas – The decisions made around the significant operating direction of Atlas will significantly impact the overall performance of the Company by determining where and how Atlas limited capital is spent without having significant revenues to keep the Company operating.

As the Company is not the primary beneficiary of Atlas, the Company did not consolidate the assets and liabilities of Atlas in our financial statements and instead accounts for the investment under the measurement alternative described in ASC 321-10-35-2 using

-19-

the available measurement alternative for equity securities that lack readily determinable fair value. As such, the Company’s investment is measured at cost less impairment, and adjusted to fair value if there are any observable price changes for identical or similar investment of the same issuer.

Atlas is funded through debt and equity. The Company's maximum exposure to loss is limited to its investment in Atlas and notes receivable and accrued interest owed to the Company from Atlas. The following is a summary of the Company’s holdings in Atlas, a VIE, in which we are not the primary beneficiary:

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

Except for the historical information contained herein, the matters addressed in this Item 2 constitute “forward-looking statements” within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended, and as identified under the heading “Cautionary Statement for Purposes of the “Safe Harbor” Provision of the Private Securities Litigation Reform Act of 1995” herein. Such forward-looking statements are subject to a variety of risks and uncertainties, including those discussed in the subsection “Risk Factors” set forth in Part II, Item 1A of this Quarterly Report on Form 10-Q and Part I, Item 1A of our most recent Annual Report on Form 10-K, and similar discussions elsewhere in this Quarterly Report on Form 10-Q and in other reports we file with the SEC from time to time, that could cause actual results to differ materially from those anticipated by our management. The Private Securities Litigation Reform Act of 1995 (the “PSLRA”) provides certain “safe harbor” provisions for forward-looking statements. All forward-looking statements made in this Quarterly Report on Form 10-Q are made pursuant to the PSLRA. We undertake no obligation to publicly release the results of any revisions to our forward-looking statements that may be made to reflect events or circumstances after the date hereof or to reflect the occurrence of unexpected events. Unless the context otherwise requires, the words “Diodes,” the “Company,” “we,” “us,” and “our” refer to Diodes Incorporated and its subsidiaries. Dollar amounts and share amounts are presented in thousands, except per share amounts, unless otherwise noted.

This management’s discussion should be read in conjunction with the management’s discussion included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2024 (“Form 10-K”), previously filed with Securities and Exchange Commission (“SEC”) on February 14, 2025.

Overview

We are a leading global manufacturer and supplier of high-quality application-specific standard products within the broad discrete, logic, analog, and mixed-signal semiconductor markets. The Company serves the industrial, automotive, computing, consumer, and communications markets. For more information about our product and markets we serve, see Note 1 – Summary of Operations and Significant Accounting Policies, included in the condensed consolidated financial statements in Item 1 above. Our products are sold primarily throughout Asia, the Americas, and Europe. We believe focusing on dependable delivery and support tailored to specific end-user applications and solution-selling approach has fostered deep customer relationships and created a key competitive advantage for us in the highly fragmented discrete, logic, analog, and mixed-signal semiconductor marketplace. We believe our close relationships with our customers have provided us with keener insight into our customers’ product needs. This results in a stronger demand for our product designs and often provides us with insight into additional opportunities for new design wins in our customers’ products.

Recent Developments

As disclosed in Part I, Item 1A: Risk Factors, of our Annual Report on Form 10-K for the fiscal year ended December 31, 2024, the Company’s business is subject to risks related to, among other factors, tariffs and other trade barriers put in the place by government authorities. The imposition of tariffs and other trade barriers by government authorities on imported goods, including raw materials and components essential to our manufacturing processes, could have significant adverse effects on our business, financial condition, and results of operations. Starting in the first quarter of 2025 and continuing into the second quarter of 2025, the United States government announced additional tariffs on goods imported into the U.S. from numerous countries and multiple nations countered with reciprocal tariffs and other actions in response. The U.S. government stated that it is willing to negotiate with other countries regarding the tariffs. If the negotiations with the other countries are unsuccessful, the tariffs may negatively impact demand for our products and result in an increase in some product costs. The Company continues to analyze the impacts of the tariffs and actions that can be taken to moderate and/or minimize their effects.

Net loss was $4.4 million, compared to net income of $14.0 million in the first quarter of 2024 and net income of $8.2 for the fourth quarter of 2024;

•

Earnings per share attributable to common stockholders was a loss of $0.10 per diluted share, compared to earnings of $0.30 per diluted share in the first quarter or 2024 and earnings of $0.18 per diluted share in the fourth quarter of 2024; and

•

Cash flow provided by operations was $56.7 million. We had $15.9 million of capital expenditures. Net cash flow was $26.2 million.

As of March 31, 2025, our cash, cash equivalents, and short-term investments were $343.9 million, and we had access to unused borrowing capacity of $225.0 million under the revolving portion of our U.S. Credit Agreement. We believe our liquidity and our

-21-

borrowing capacity will allow us to cover our cash needs for working capital, capital expenditures, and acquisitions for at least the next 12 months.

Net sales for the three months ended March 31, 2025, exceeded the Company’s expectations due to better than anticipated seasonal performance across the computing, communications and consumer markets in Asia. Additionally, Europe and North America were up double digits sequentially as those regions showed signs of improvement from recent lows, highlighted by increasing opportunities for Diodes’ products in artificial-intelligence-related applications. Automotive and industrial markets totaled 42% of first quarter net sales as we continue to see expanding automotive content and design opportunities. Additional indicators of improving conditions are channel inventory dollars and days sales outstanding continue to decrease and appear to be more aligned with real demand and historical point of sales levels. Although the inventory depletion is a positive sign for the Company and the broader market, it does not directly benefit loading at our manufacturing facilities, and therefore, our gross margins. As channel inventory continues to normalize and global demand improves, we should see a more material expansion to gross margin. Additionally, further recovery in our higher margin automotive and industrial markets will also contribute to driving future margin improvement.

Net sales increased approximately $30.1 million, or 10.0%, for the three months ended March 31, 2025, compared to the same period last year, primarily due to increased demand in the Asia region. During the three months ended March 31, 2025,

-22-

weighted-average sales price increased 10.0% and volume was flat, when compared to the same period in 2024. The increase in weighted-average sales price was primarily due to product mix.

The table below sets forth our product revenue as a percentage of total product revenue by end-user market for the three months ended March 31, 2025 and 2024:


	Three Months Ended
	March 31,
	2025	2024
Industrial	23%	23%
Automotive	19%	18%
Computing	27%	25%
Consumer	17%	20%
Communications	14%	14%

For the three months ended March 31, 2025, gross profit increased approximately 5.1% when compared to the same period last year primarily due to higher net sales. Gross profit margin for the three-month periods ended March 31, 2025 and 2024 was 31.5% and 33.0%, respectively. The decrease in gross profit margin was primarily due to lower factory utilization.

Operating expenses for the three months ended March 31, 2025, increased $11.9 million when compared to the three months ended March 31, 2024. Operating expenses as a percentage of net sales were 31.1% and 30.3% for the three months ended March 31, 2025 and 2024, respectively. SG&A increased approximately $5.0 million as compared to the same period last year reflecting an increase in discretionary benefits of $5.7 million, partially offset by decreases in payroll expenses of $1.5 million. The increase in discretionary benefits in 2025 when compared to 2024 is partially related to a reversal of bonus accruals in 2024 that were not paid. SG&A, as a percentage of net sales, was 17.7% and 17.8% for the three months ended March 31, 2025 and 2024, respectively. The lower levels of discretionary benefits in SG&A reflect lower accruals based on the Company’s performance being lower than in 2024. Research and development expenses (“R&D”) were flat. R&D, as a percentage of net sales, was 11.6% and 11.2% for the three months ended March 31, 2025 and 2024, respectively.

Interest income increased $1.2 million, or 26.0%, for the three months ended March 31, 2025, compared to the same period last year, reflecting interest income received in the Company’s derivative hedging instruments. Interest expense was flat for the three months ended March 31, 2025, compared to the same period last year. During the three months ended March 31, 2025, the Company recognized an impairment loss on an equity investment of $5.8 million, due to a decline in the value of the investment. The change in unrealized (loss) gain on investments in 2025 compared to 2024 was to mark to market adjustments to adjust the value of the investment.

We recognized an income tax expense of approximately $0.0 million and $3.5 million for the three months ended March 2025 and 2024, respectively. The decrease in income taxes for 2025 compared to 2024 was primarily attributable to a decrease in pretax book income.

Financial Condition

Liquidity and Capital Resources

Our primary source of liquidity is cash flow from operations. Additional sources of liquidity are cash and cash equivalents, short-term investments, and our credit facilities. Our cash and cash equivalents and restricted cash increased from $314.7 million at December 31, 2024 to $341.0 million at March 31, 2025. This increase in cash, cash equivalents, and restricted cash reflects normal operations of the Company. As of March 31, 2025, we had short-term investments totaling $8.2 million. These investments are highly liquid with maturity dates greater than three months at the date of purchase. We generally can access these investments in a relatively short time frame but in doing so we generally forfeit all earned and future interest income.

At March 31, 2025 and December 31, 2024, our working capital was $868.0 million and $848.6 million, respectively. We expect cash generated by our operations together with existing cash, cash equivalents, short-term investments, and available borrowing under credit facilities to be sufficient to cover our cash needs for working capital, capital expenditures, and acquisitions for at least the next 12 months.

Our undistributed foreign earnings continue to be indefinitely reinvested in foreign operations, with limited exceptions related to earnings of certain European and Asian subsidiaries. As of March 31, 2025, our foreign subsidiaries held approximately $249.5 million of cash, cash equivalents and investments of which approximately $95.3 million would be subject to a potential non-U.S. withholding tax if distributed outside the country in which the cash is currently held. The $95.3 million is held in Germany, China, Korea, and Taiwan.

Short-term debt

Our Asia subsidiaries maintain short-term credit facilities with several financial institutions through our foreign entities worldwide totaling $125.4 million. Other than two Taiwanese credit facilities that are collateralized by assets, our foreign credit lines are unsecured,

-23-

uncommitted, and contain no restrictive covenants. These credit facilities bear interest at the Taipei Interbank Offering Rate (or similar indices) plus a specified margin. Interest payments are due monthly on outstanding amounts under the credit lines. The unused and available credit under the various facilities as of March 31, 2025, was approximately $93.9 million, net of $31.0 million advanced under our foreign credit lines and $0.4 million of credit used for import and export guarantee.

Long-term debt

The Company maintains a long-term credit facility (“Credit Agreement”). The Credit Agreement consists of a Revolving Credit Facility in the amount of $225.0 million, including a swing line sublimit equal to the lesser of $50.0 million and the Revolving Credit Facility, a letter of credit sublimit equal to the lesser of $100.0 million and the Revolving Credit Facility, and an alternative currency sublimit equal to the lesser of $40.0 million and the Revolving Credit Facility. The Company has the option to increase the Revolving Credit Facility and/or incur Incremental Term Loans in an aggregate principal amount of up to $350.0 million. The Credit Agreement bears interest at Term SOFR or similar other indices plus a specified margin and matures in May 2028. There was no outstanding balance under the Credit Agreement at March 31, 2025.

Because some of our outstanding debt is subject to variable interest rates, higher interest rates will potentially increase our overall debt service cost. If interest rates rise globally, our cost of capital may increase in the future.

Discussion of Cash Flows

The table below sets forth a summary of the condensed consolidated statements of cash flows:


	Three Months Ended March 31,
	2025			2024
Net cash flows from operating activities	$	56,743		$	(31,143	)
Net cash flows from investing activities		(28,458	)		(18,279	)
Net cash flows from financing activities		(1,318	)		3,182
Effect of exchange rate changes on cash and cash equivalents		(733	)		(1,683	)
Change in cash and cash equivalents, including restricted cash	$	26,234		$	(47,923	)

Operating Activities

Net cash flows from operating activities for the three months ended March 31, 2025 was $56.7 million. The following recurring operating items gave rise to the calculation of net cash flows from operating activities for the three months ended March 31, 2025: Depreciation and amortization of intangible assets of $35.9 million, a net increase of $12.1 million of changes in working capital accounts, a $4.0 million non-cash loss on investments related to mark-to-market adjustments to adjust the value of the investment, and share-based compensation of $6.4 million. These increases were partially offset by a net loss of $2.8 million. During the three months ended March 31, 2025, the Company recorded a $5.8 million non-cash impairment charge related to the decrease in value of a previously made equity investment, the result of which is an increase to operating cash flow.

Net cash flows from operating activities for the three months ended March 31, 2024 was $31.1 million. Net cash flows from operating activities for the three months ended March 31, 2024 resulted from net income of $15.3 million, depreciation and amortization of intangible assets of $34.8 million and share-based compensation of $5.1 million. The increases were offset by a decrease in operating asset and liability accounts of $77.4 million and a gain on disposal of property plant and equipment of $4.9 million.

Investing Activities

Net cash and cash equivalents from investing activities was ($28.5) million for the three months ended March 31, 2025. Net cash and cash equivalents from investing activities for the three months ended March 31, 2025 was primarily due to purchases of property, plant, and equipment of $15.9 million, or 4.8% of net sales, the expiration of a hedge instrument of $6.9 million, and the acquisition of the minority interest in a joint venture in Taiwan for approximately $4.1 million, bringing the Company’s ownership to 100%. We expect capital expenditures for the twelve months ended December 31, 2025 to be within our target model of 5% to 9% of net sales.

Net cash and cash equivalents from investing activities was $18.3 million for the three months ended March 31, 2024. Net cash and cash equivalents from investing activities for the three months ended March 31, 2024 was primarily due to purchases of property, plant and equipment of $20.4 million, or 6.7% of net sales.

Financing Activities

Net cash and cash equivalents from financing activities was ($1.3) million for the three months ended March 31, 2025. Net cash provided by financing activities in the three months ended March 31, 2025 consisted primarily of $0.2 million of net increases in our debt and taxes paid on net share settlements of $1.5 million. Net cash and cash equivalents provided by financing activities was $3.2 million for the three months ended March 31, 2024. Net cash and cash equivalents from financing activities in the three months ended March 31, 2024 consisted primarily of $8.6 million of net increases in our debt, partially offset by taxes paid on net share settlements of $5.4 million.

Use of Derivative Instruments and Hedging

We use, or may use, interest rate swaps, foreign exchange forward contracts, and cross currency swaps to provide a level of protection against interest rate risks and foreign exchange exposure.

Hedges of Interest Rate Risk

Our objectives in using interest rate derivatives are to add stability to interest expense and to manage exposure to interest rate movements. To accomplish these objectives, we primarily use interest rate swaps, including interest rate collars, as part of its interest rate risk management strategy. Interest rate swaps designated as cash flow hedges involve the receipt of variable amounts from a counterparty in exchange for us making fixed-rate payments over the life of the agreements without exchange of the underlying notional amount.

Hedges of Foreign Currency Risk

We are exposed to fluctuations in various foreign currencies against our different functional currencies. We use foreign currency forward agreements to manage this exposure and to preserve the economic value of foreign currency denominated monetary assets and liabilities. These instruments are not designated for hedge accounting treatment in accordance with ASC No. 815. The fair value of our foreign exchange hedges approximates zero.

Hedges of Net Investment Risk

We make use of cross-currency swaps and foreign-currency forward contracts to decrease the foreign exchange risk inherent in our investment in some of our foreign subsidiaries.

Off-Balance Sheet Arrangements

We do not have any transactions, arrangements, or other relationships with unconsolidated entities that will affect our liquidity or capital resources. We have no special purpose entities that provide off-balance sheet financing, liquidity, or market or credit risk support, nor do we engage in leasing, swap agreements, or outsourcing of research and development services that could expose us to liability that is not reflected on the face of our financial statements.

Contractual Obligations

There have been no material changes in our Contractual Obligations as disclosed in our Annual Report on Form 10-K for the fiscal year ended December 31, 2024, filed with the SEC on February 14, 2025.

Critical Accounting Estimates

Our critical accounting estimates are described in Item 7, Management’s Discussion and Analysis of Financial Condition and Results of Operations, and in the notes to our consolidated financial statements contained in our Annual Report on Form 10-K for the fiscal year ended December 31, 2024, filed with the SEC on February 14, 2025. Any new accounting estimates or updates to existing accounting estimates as a result of new accounting pronouncements have been discussed in the notes to our condensed consolidated financial statements in this Quarterly Report on Form 10-Q in Note 1 – Summary of Operations and Significant Accounting Policies. The application of our critical accounting estimates may require management to make judgments and estimates about the amounts reflected in the condensed consolidated financial statements. Management uses historical experience and all available information to make these estimates and judgments, and different amounts could be reported using different assumptions and estimates.

Item 3. Quantitative and Qualitative Disclosures About Market Risk.

There have been no material changes to our market risks as disclosed in our Annual Report on Form 10-K for the fiscal year ended December 31, 2024, filed with the SEC on February 14, 2025.

Item 4. Controls and Procedures.

Our Chief Executive Officer, Keh-Shew Lu, and Chief Financial Officer, Brett R. Whitmire, with the participation of our management, carried out an evaluation, as of March 31, 2025, of the effectiveness of our disclosure controls and procedures (as defined in Exchange Act Rules 13a-15(e) and 15d-15(e)). Based upon that evaluation, the Chief Executive Officer and the Chief Financial Officer believe that, as of the end of the period covered by this Quarterly Report on Form 10-Q, our disclosure controls and procedures are effective at the reasonable assurance level to ensure that information required to be included in this Quarterly Report is:

•

recorded, processed, summarized, and reported within the time period specified in the Commission’s rules and forms; and

•

accumulated and communicated to our management, including the Chief Executive Officer and the Chief Financial Officer, to allow timely decisions on required disclosure.

Disclosure controls and procedures, no matter how well designed and implemented, can provide only reasonable assurance of achieving an entity’s disclosure objectives. The likelihood of achieving such objectives is affected by limitations inherent in disclosure controls and procedures. These include the fact that human judgment in decision-making can be faulty and that breakdowns in internal control can occur because of human failures such as simple errors, mistakes, or intentional circumvention of the established processes.

Changes in Internal Controls over Financial Reporting

There was no change in our internal control over financial reporting, known to our Chief Executive Officer or Chief Financial Officer, that occurred in the three months ended March 31, 2025, that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

PART II—OTHER INFORMATION

Item 1. Legal Proceedings.

However, litigation is subject to inherent uncertainties, and unfavorable rulings could occur. An unfavorable ruling could include monetary damages, which could impact our business and operating results for the period in which the ruling occurs or future periods.

PLEASE NOTE: It is inappropriate for investors to assume the accuracy of any covenants, representations or warranties that may be contained in agreements or other documents filed as exhibits to this Quarterly Report on Form 10-Q. In certain instances the disclosure schedules to such agreements or documents contain information that modifies, qualifies and creates exceptions to the representations, warranties and covenants. Moreover, some of the representations and warranties may not be complete or accurate as of a particular date because they are subject to a contractual standard of materiality that is different from those generally applicable to stockholders and/or were used for the purpose of allocating risk among the parties rather than establishing certain matters as facts. Accordingly, you should not rely on the representations and warranties as characterizations of the actual state of facts at the time they were made or otherwise.
