REPORT ON CORPORATE INCOME TAX INFORMATION

Introduction

Overview Since 2016, ASML, as a multinational enterprise headquartered in the Netherlands with consolidated revenues exceeding EUR 750 million, has submitted its annual Country by Country Report (hereafter "CbCR") to the Dutch tax authorities. In addition, ASML has submitted its CbCR to the Taiwanese tax authorities. Beginning with the financial year commencing on January 1, 2025, ASML will publicly disclose its CbCR in accordance with the European Union Directive on the Disclosure of Income Tax Information by Certain Undertakings and Branches (Directive (EU) 2021/2101). Consistent with ASML’s commitment to transparency, the public disclosure will cover all jurisdictions in which the group operates. ASML's operating model ASML’s tax position reflects the substance of its business operations: the sale of lithography systems and related products and services arising from manufacturing and R&D activities. We operate a centralised principal model, centred on our campus in Veldhoven, the Netherlands. ASML Netherlands B.V. serves as the global headquarters and principal company of the ASML Group. In addition to group management and control functions, ASML Netherlands B.V. develops and manufactures ASML systems and owns and controls the associated intangible assets. It is supported by limited-risk entities (for example, distributors and manufacturers) across multiple jurisdictions, remunerated on a routine basis. The notable exception is the Cymer Light Sources business line, for which Cymer LLC in the United States acts as the principal.

Conclusion

ADDITIONAL INFORMATION 1. Data sources • The CbCR reporting data of the respective Constituent Entities (“CEs”) is based on the data used for financial consolidation reporting purposes based on US GAAP. In case of multiple CEs in a jurisdiction, irrespective of applicable country consolidation, reporting took place on an aggregate basis at a jurisdictional level. • There may be differences between figures prepared under US GAAP and those in audited standalone financial statements of the CEs, including due to differences in revenue recognition rules, among other things. • Amounts in the "Overview of information on country-by-country basis" are reported in EUR in full whole units. Employees are reported in full number of FTE. 2. Definitions In compiling the "Overview of information on country-by-country basis," ASML has followed the definitions as included in the OECD Guidance and Dutch legislation: • Revenue: The sum of revenues of all CEs of the MNE Group generated in the relevant tax jurisdiction, including sales of inventory, property, services, royalties, interest (income and expense), premiums, and any other amounts. Revenue excludes dividends from CEs. Currency gains/losses are not included. • Profit before tax: The sum of profit before income tax for all CEs resident for tax purposes in the relevant jurisdiction, including all extraordinary income and expenses. Income from subsidiaries arising from equity method accounting and dividends from CEs are excluded. • Income tax paid: Cash tax paid during the current (reporting) year, whether relating to the current, prior, or future years. This includes withholding taxes (“WHT”) paid by other (associated) entities with respect to payments to the CE (excluding WHT on dividends). Tax refunds, if any, are reported within Income Tax Paid as negative amounts. • Income tax accrued: The current tax expense accrued for the reporting period. It excludes deferred tax, cash tax payments, and prior-year adjustments. • Stated capital: All amounts paid on shares outstanding (including share premium, additional paid-in capital, and shares issued at a discount or part-paid). This excludes, among other things, Other Comprehensive Income and Translation Adjustments. For ASML Holding N.V., Stated Capital excludes treasury shares (buy-backs of own shares). • Accumulated earnings: All amounts within equity originating from retained earnings. • Employees: Full-time equivalent (FTE) data as at December 31, 2025. • Tangible assets other than cash and cash equivalents: Tangible assets other than cash and cash equivalents include Property, plant and equipment; inventory; and right-of-use assets. 3. Reconciliations The following data included in the "Overview of information on country-by-country basis" reconciles with the data stated in the consolidated financial statements of Annual Report 2025: • Revenues - Unrelated Parties reconcile with the total net sales and the net interest (and other) income of the group as reported in the Consolidated statements of operations of the Annual Report 2025. • Number of employees reconcile with the number included in Note 18 of the Notes to the Consolidated financial statements of the Annual Report 2025. The other elements of the "Overview of information on country-by-country basis" do not reconcile directly with the data stated in the Annual Report 2025 due to intercompany profit elimination (applicable for Revenues - Related Parties, Profit (loss) before tax, and Tangible assets other than cash and cash equivalents) and/or differences in definitions as per US GAAP and CbCR guidance (applicable for income tax paid and income tax accrued). 4. Observations "Overview of information on country-by-country basis" • Accumulated earnings include negative figures for certain CEs located in Germany, South Korea, Malaysia, the Netherlands, Taiwan, and US. • The negative balance reported under ‘Tangible assets other than cash and cash equivalents’ for the United Kingdom results from a temporary timing discrepancy between projected costs and actual costs recorded for service orders in progress. 5. Mergers and acquisitions • No entities have been incorporated during the year ended December 31, 2025. • ASML Hong Kong Ltd. has been placed in members’ voluntary liquidation on September 30, 2025. • ASML Hong Kong Ltd. – Hong Kong PE (in South Korea) has been placed in voluntary liquidation on September 12, 2025. • Hermes Microvision (Shanghai) Co., Ltd. has been liquidated on March 13, 2025. • No other liquidations or dissolutions occurred during the year ended December 31, 2025. • In 2022, the activity of ASML Trading B.V. – Netherlands PE (in Russia) ceased and the procedure for its de-registration is ongoing. 6. Other comments • In determining the nature of the main business activities of CEs in the “List of subsidiaries and activities," ASML has followed the Group's Operating model as well as relevant transfer pricing characterizations of the CEs within the ASML value chain as documented in the Group’s Transfer Pricing Policy. • For CEs - ASML Repair Center Korea Ltd., ASML (Beijing) Equipment Repair Company Ltd., and EO Technical Solutions LLC - one of the main business activities marked in the “List of subsidiaries and activities" is “Other” as it allows to further clarify the nature of the activities performed. These CEs are involved in the provision of repair services for parts to related parties
