Basis of Presentation The condensed consolidated financial data at December 31, 2022 are derived from audited financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2022 filed with the Securities and Exchange Commission (“SEC”) on February 10, 2023 (“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 nine months ended September 30, 2023 are not necessarily indicative of the results that may be expected for other interim periods or the year ending December 31, 2023. 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.

Earnings per Share

	Sep. 30, 2023
Earnings Per Share [Abstract]
Earnings per Share	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. During the nine months ended September 30, 2023 and 2022, we paid no dividends on our Common Stock. The table below sets forth the reconciliation between net income and the weighted average shares outstanding used for calculating basic and diluted EPS: Three Months Ended Nine Months Ended September 30, September 30, 2023 2022 2023 2022 Earnings (numerator) Net income attributable to common stockholders $ 48,720 $ 86,386 $ 201,890 $ 239,232 Shares (denominator) Weighted average common shares outstanding (basic) 45,936 45,475 45,758 45,283 Dilutive effect of stock options and stock awards outstanding 384 539 538 655 Adjusted weighted average common shares outstanding (diluted) 46,320 46,014 46,296 45,938 Earnings per share attributable to common stockholders Basic $ 1.06 $ 1.90 $ 4.41 $ 5.28 Diluted $ 1.05 $ 1.88 $ 4.36 $ 5.21 Stock options and stock awards excluded from EPS 271 104 94 83

Income Tax Provision	NOTE 5 – Income Tax Provision The table below sets forth information related to our income tax expense: Three Months Ended Nine Months Ended September 30, September 30, 2023 2022 2023 2022 Domestic pre-tax income $ 21,480 $ 53,967 $ 118,209 $ 185,839 Foreign pre-tax income $ 39,026 $ 55,179 $ 131,845 $ 115,337 Income tax provision $ 10,674 $ 20,172 $ 44,514 $ 55,279 Effective tax rate 17.6 % 18.5 % 17.8 % 18.4 % Impact of tax holidays on tax expense $ ( 216 ) $ ( 173 ) $ 111 $ 1,118 Earnings per share impact of tax holidays: Basic $ - $ 0.01 $ - $ ( 0.02 ) Diluted $ - $ 0.01 $ - $ ( 0.02 ) The decrease in the effective tax rate for the three and nine months ended September 30, 2023, when compared to the three and nine months ended September 30, 2022, is primarily attributable to the geographical mix of pre-tax income and loss across tax jurisdictions relative to the Company’s consolidated pre-tax income and the impact of changes to the outside basis difference in foreign subsidiaries where the Company does not assert permanent reinvestment. Our undistributed foreign earnings continue to be indefinitely reinvested in foreign operations, with limited exceptions related to certain earnings of our 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 2012, or for the tax years 2015 - 2018. We are no longer subject to China income tax examinations by tax authorities for tax years before 2012. 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 2016. 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 September 30, 2023, the gross amount of unrecognized tax benefits was approximately $ 51.5 million. 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.

Restricted stock awards and restricted stock units 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 granted 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 September 30, 2023, total unrecognized share-based compensation expense related to share grants was approximately $ 71.6 million, before income taxes, and is expected to be recognized over a weighted average period of approximately 2.4 years. Stock Modification . During the nine months ended September 30, 2023 we modified previously granted stock awards for two corporate officers who retired.

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 and distribution sales (“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.

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 SOFR 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 September 30, 2023, was approximately $ 109.4 million, net of $ 29.4 million advanced under our foreign credit lines and $ 0.4 million credit used for import and export guarantee. Long-term debt On May 26, 2023 , the Company, Diodes Holdings UK Limited (the “Foreign Borrower” and, collectively with the Company, the “Borrowers”), and certain subsidiaries of the Company as guarantors, entered into a Third Amended and Restated Credit Agreement (the “Credit Agreement”) that amends and restates that certain Second Amended and Restated Credit Agreement dated as of May 29, 2020 (as amended, modified and/or supplemented from time to time prior to the date of the Credit Agreement, the “Existing Credit Agreement”). Certain capitalized terms used in this description of the Credit Agreement have the meanings given to them in the Credit Agreement, which is attached as Exhibit 10.1 to our Current Report on Form 8-K that we filed with the SEC on June 2, 2023. The Existing Credit Agreement consisted of a term loan with no outstanding balance as of the date of the Credit Agreement and a $ 225.0 million revolving senior credit facility with nothing drawn as of the date of the Credit Agreement. The Credit Agreement, which represented a complete amendment and restatement of the Existing 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 Credit Agreement contains certain financial and non-financial covenants, including, but not limited to, a maximum Consolidated Leverage Ratio, a minimum Consolidated Interest Coverage Ratio, and restrictions on liens, indebtedness, investments, fundamental changes, dispositions, and restricted payments (including dividends and share repurchases). Furthermore, under the Credit Agreement, restricted payments, including dividends and share repurchases, are permitted in certain circumstances, including while the pro forma Consolidated Leverage Ratio is, both before and after giving effect to any such restricted payment, at least 0.25 to 1.00 less than the maximum permitted under the Credit Agreement . The Revolving Credit Facility matures on May 26, 2028.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Financial Instruments	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 September 30, 2023 and December 31, 2022, we had $ 220.3 million and $ 183.1 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.

Investments, Debt and Equity Securities [Abstract]
Equity Investments	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 September 30, 2023, the Company had $ 55.6 million of investments accounted for under the measurement alternative. During the nine months ended September 30, 2023 and September 30, 2022, the Company recognized upward adjustments in value of $ 15.3 million and $ 3.9 million, respectively, for a cumulative total of upward adjustments of $ 19.2 million on these investments. These adjustments were based on the valuation of additional equity issued by the investee which was deemed to be an observable transaction of a similar investment under ASC 321. The upward adjustments were recorded within other income, in the condensed consolidated statement of operations. The upward fair value adjustment represents a nonrecurring fair value measurement based on observable price changes. Variable Interest Entities The Company determines at the inception of each arrangement whether an entity in which it has made an investment or in which the Company has other variable interests is considered a variable interest entity (“VIE”). The Company consolidates VIEs when it is the primary beneficiary. The Company is the primary beneficiary of a VIE when it has the power to direct activities that most significantly affect the economic performance of the VIE and has the obligation to absorb the majority of their losses or benefits. If the Company is not the primary beneficiary of a VIE, the Company accounts for the investment or other variable interests in a VIE in accordance with applicable GAAP. Each reporting period, the Company assesses whether any changes in our interest or relationship with the entity affect our determination of whether the entity is a VIE and, if so, whether the Company is the primary beneficiary. Unconsolidated Variable Interest Entity During July 2021, the Company acquired an interest in an early stage privately held fabless wafer design company (“PWDC”), 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 May 2023, the Company acquired an additional interest in PWDC by purchasing $ 13.9 million of preferred stock. As part of the May 2023 agreement, the Company’s previously held convertible note converted to $ 5.2 million of preferred stock and as of September 30, 2023, the Company owns more than 50 % of PWDC. T he Company determined that PWDC is a VIE and while the Company does no business with PWDC, other than the investment transactions described above, the Company determined that PWDC is a related party. The Company does not have the power to direct the activities that most significantly impact PWDC, and therefore, has determined that the Company is not the primary beneficiary. As the Company is not the primary beneficiary of PWDC, the Company did not consolidate the assets and liabilities of the PWDC in our financial statements and instead accounted for the investment under the measurement alternative described in ASC 321-10-35-2 using 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. As a result of entering into an additional interest in PWDC in May 2023, the Company recorded an upward adjustment of $ 15.3 million during the nine months ended September 30, 2023. PWDC is funded through debt and equity. The Company's maximum exposure to loss is limited to its investment in PWDC and notes receivable and accrued interest owed to the Company from the PWDC. The following is a summary of the Company’s holdings in the VIE, in which we are not the primary beneficiary: September 30, 2023 December 31, 2022 Privately Held Wafer Design Company ("PWDC") VIE total assets $ 25,134 $ 13,671 VIE total liabilities 379 6,625 Diodes' equity in VIE $ 44,420 $ 10,000 Diodes' note receivable from VIE - 5,000 Diodes' interest receivable from VIE - 222 Diodes' maximum exposure to loss $ 44,420 $ 15,222

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 nine months ended September 30, 2023 are not necessarily indicative of the results that may be expected for other interim periods or the year ending December 31, 2023. 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.

Objectives for using derivative instruments	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.
