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 and six months ended June 30, 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 (“FASB”) issued Accounting Standards Update (“ASU”) 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.

In May 2025, the FASB issued ASU 2025-03, “Business Combination and Consolidation: Determining the Accounting Acquirer in the Acquisition of a Variable Interest Entity”(“ASU 2025-03”). ASU 2025-03 provides clarifying guidance on determining the accounting acquirer in certain transactions involving VIEs. The update aims to improve consistency and comparability in financial reporting, especially when companies merge with a special-purpose acquisition company (“SPAC”). ASU 2025-03 requires entities to apply the same factors used for determining the accounting acquirer in other acquisition transactions. Essentially, it aims to make financial reporting more comparable and decision-useful for investors by ensuring that the accounting acquirer is appropriately identified in acquisitions of VIEs, particularly in SPAC transactions. ASU 2024-03 is effective for fiscal years beginning after December 15, 2026 including interim periods within those annual periods, with early adoption permitted. The Company is currently evaluating the impact this amended guidance may have on its financial statements.

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:

Earnings per share impact of tax holidays:
Basic$0.01$-$0.01$-
Diluted$0.01$-$0.01$-

The decrease in effective tax rate for the three and six months ended June 30, 2025, when compared to the three and six months ended June 30, 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 2014. 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 June 30, 2025, the gross amount of unrecognized tax benefits was approximately $45.1 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.

-13-

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.

One Big Beautiful Bill Act

On July 4, 2025, the One Big Beautiful Bill Act was signed into law in the U.S., which contains a broad range of income tax provisions affecting businesses. We are evaluating the effects of the legislation, which we expect will likely not have a material impact on our financial statements. As the legislation was enacted after the close of our second quarter, the impacts are not included in our operating results for the six months ended June 30, 2025.

NOTE 6 – Share-Based Compensation

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

Three Months Ended · Six Months Ended

Total share-based compensation expense$5,793$4,245$12,179$9,318

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 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 June 30, 2025, total unrecognized share-based compensation expense related to share grants was approximately$46.8 million, before income taxes, and is expected to be recognized over a weighted average period of approximately 2.2 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 ourchief 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 June 30, 2025, two customers accounted for approximately $45.9 million and $43.8 million, or 12.5% and 12.0%, respectively, of our net sales. During thesix months ended June 30, 2025, two customers accounted for approximately $82.9 million and $79.5 million, or 11.9% and 11.4%, respectively, or our net sales. As of June 30, 2025, two customers accounted for approximately $48.2 million and $35.8 million, or 15.4% and 11.4%, respectively, of the Company’s outstanding accounts receivable.

During the three months ended June 30, 2024, one customer accounted for approximately $33.9 million or 10.6% of our net sales. During thesix months ended June 30, 2024, one customer accounted for approximately $76.6 million or 12.3% of our net sales. As of June 30, 2024, one customer accounted for approximately 11.8% of our outstanding accounts receivable. 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$115.5 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

-16- available credit under the various facilities as of June 30, 2025, was approximately$87.5 million, net of$27.6 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 wasno outstanding balance at June 30, 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 $40.1 million at June 30, 2025. As of June 30, 2025, we also had a commitment to purchase approximately$69.6 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 June 30, 2025, the underfunded liability for this defined benefit plan was approximately $5.2 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 June 30, 2025 and December 31, 2024, we had$315.6 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.

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 June 30, 2025 and December 31, 2024, these investments totaled approximately $18.5 million and $17.2 million, respectively.

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 $5.7 million of wafers from Nuvoton that ends in the second quarter of 2026. 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.

-19-

In May 2025, the Company entered into a Joint Venture Agreement (the “Joint Venture Agreement”) with Global Advanced Packaging Test Limited (“GAPT”) to acquire a 43% interest and joint control of ATX Semiconductor SDN (“ATX”), a Malaysian private limited liability company, with the purpose of building synergies related to testing and packaging. ATX is a related party for the Company.

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 June 30, 2025, the Company had$97.8 million of investments accounted for under the measurement alternative. During the six months ended June 30, 2025, the Company recorded $25.6 million of non-cash mark-to-market adjustments related to the value of a previously made equity investments.

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 and the Company’s previously held convertible note converted to $5.2 million of preferred stock. In June 2025, the Company acquired an additional interest in Atlas by purchasing $12.3 million of preferred stock. In connection with the additional investment in Atlas in June 2025, the Company recorded an upward mark-to-market adjustment of $33.3 million to adjust the value of the investment. The primary purpose for providing the additional investments in Atlas was to provide for continued access to developing technology with potential future benefit to the Company. At June 30, 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;

-20-

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 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:

June 30, 2025December 31, 2024
VIE total assets$41,660$20,273
VIE total liabilities10,7454,945
Diodes' equity in VIE$90,035$44,420
Diodes' note receivable from VIE9,0004,000
Diodes' interest receivable from VIE403245
Diodes' maximum exposure to loss$99,438$48,665

ATX Semiconductor SDN

In May 2025, the Company entered into a Joint Venture Agreement with GAPT to acquire a 43% interest and joint control of ATX, a Malaysian private limited liability company, with the purpose of building synergies related to testing and packaging.

The ATX joint venture meets the accounting definition of a joint venture where neither party has unilateral control of the entity and both parties have joint control over the decision-making process in ATX. As such, the Company uses the equity method to account for its share of the investment in ATX.

The carrying value of the equity investment is $30.0 million as of June 30, 2025, which represents the initial cost of the investment in ATX. The Company intends to record equity method earnings of the joint venture on a 3-month lag. As such, the Company will recognize the equity method earnings from the date of formation through June 30, 2025 within the Condensed Consolidated Statements of Operations for the three months ended September 30, 2025.

NOTE 15 – Acquisitions and Divestitures
