Digital Realty Trust, Inc. (NYSE: DLR) and its worldwide subsidiaries (“DLR Group”) is a leading global provider of data center, colocation and interconnection solutions for customers across a variety of industry verticals. This Public Country-by-Country Reporting (“CbCR”) (“Public CbCR”) report has been prepared for DLR Group for the fiscal year ended 31 December 2025 (“FY25”) in accordance with the EU Directive 2021/2101 amending Directive 2013/34/EU on Public CbCR of the European Parliament and of the Council as implemented in relevant EU Member States (the “EU Public CbCR Directive”). The Public CbCR requires disclosure of selected financial and tax information on a country-by-country basis for qualifying multinational groups. DLR Group has prepared the report in USD based on our U.S. GAAP (United States generally accepted accounting principles) financial statements. In line with the EU Public CbCR Directive, the Group discloses information separately for each EU Member State in which it operates, as well as for jurisdictions included on the EU list of non-cooperative jurisdictions for tax purposes (and certain jurisdictions on the ‘grey list’ where required). All other non-EU jurisdictions are presented on an aggregated basis as ‘All other tax jurisdictions’. Digital Realty Trust, Inc. is the non-EU ultimate parent undertaking (“UPE”) for DLR Group. The UPE has prepared and hereby published a qualifying Public CbC report, and one of its constituent entities in Ireland, Digital Realty (Management Company) Limited, is the single EU undertaking responsible for filing and publication under the filing hub approach. This report is made publicly available on the website of DLR Group’s UPE. For this Public CbC report, definitions follow OECD guidance and align with those used in DLR Group’s confidential OECD CbC report filed with tax authorities (“OECD private CbC report”). The following definitions apply: i. Revenue - Total revenue generated by constituent entities within a jurisdiction, comprising both revenue from unrelated parties and revenue from related parties (intra‑group transactions including finance income). ii.
