For purposes of the Group’s primary financial reporting outside the United States, the Group prepares its consolidated financial statements in accordance with IFRS as endorsed by the EU. For purposes of the Group’s consolidated financial statements prepared in accordance with IFRS as endorsed by the EU, the Group applies fair value hedge accounting for portfolio hedges of interest rate risk (fair value macro hedges) in accordance with the EU carve out version of IAS 39. The purpose of applying the EU carve out version of IAS 39 is to align the Group’s hedge accounting approach with its risk management practice and the accounting practice of its major European peers. Under the EU carve out version of IAS 39 fair value macro hedge accounting may be applied to core deposits. In addition, the EU carve out version of IAS 39 hedge ineffectiveness is only recognized when the revised estimate of the amount of cash flows in scheduled time buckets falls below the original designated amount of that bucket. If the revised amount of cash flows in scheduled time buckets is more than the original designated amount, then there is no hedge ineffectiveness. Under IFRS as issued by the IASB, hedge accounting for fair value macro hedges cannot be applied to core deposits. In addition, under IFRS as issued by the IASB hedge ineffectiveness arises for all fair value macro hedge accounting relationships whenever the revised estimate of the amount of cash flows in scheduled time buckets is either more or less than the original designated amount of that bucket. The EU carve out version of IAS 39 also removes the prohibition on identifying a benchmark risk component in a financial instrument priced at sub–benchmark. This may arise when financial instruments carry a negative spread such that the identified non–contractually specified risk component is larger than the interest carry on the contract itself. The application of the EU carve out version of IAS 39 had a negative impact of € 688 million on profit before tax and of € 496 million on profit after tax for the three-month period ended June 30, 2026, compared to a negative impact of € 535 million on profit before tax and of € 383 million on profit after tax for the three-month period ended June 30, 2025. The application of the EU carve out version of IAS 39 had a positive impact of € 166 million on profit before tax and of € 119 million on profit after tax for the six-month period ended June 30, 2026, compared to a negative impact of € 144 million on profit before tax and of € 103 million on profit post taxes for the six-month period ended June 30, 2025. The Group’s regulatory capital and ratios thereof are also reported on the basis of the EU carve out version of IAS 39. As of June 30, 2026, the application of the EU carve out had a cumulative negative impact on the CET1 capital ratio of about 53 basis points compared to a cumulative negative impact of about 75 basis points as of June 30, 2025. The preparation of financial information under IFRS requires management to make estimates and assumptions for certain categories of assets and liabilities. These estimates and assumptions affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the balance sheet date and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from management’s estimates, especially in relation to potential impacts from tariffs or inflation and broader changes in the political and geopolitical environment (e.g., war in Ukraine or Middle East conflict), and the results reported should not be regarded as necessarily indicative of results that may be expected for the entire year.

The interim consolidated financial statements of Deutsche Bank Aktiengesellschaft, Taunusanlage 12, Frankfurt am Main,

Germany and its subsidiaries (collectively the “Group” or “Deutsche Bank”) for the six-month period ended June 30, 2026,

is stated in euros, the presentation currency of the Group. It has been prepared based on the International Financial

Reporting Standards (IFRS) as issued by the International Accounting Standards Board (IASB). The interim consolidated

financial statements are prepared in accordance with the requirements of IAS 34 relating to interim financial reporting.

The Group’s interim consolidated financial statements are unaudited and include the consolidated balance sheet as of

June 30, 2026, the related consolidated statements of income and comprehensive income for the six-month period

ended June 30, 2026, as well as other information.

The Group’s interim consolidated financial statements should be read in conjunction with the audited consolidated

financial statements of Deutsche Bank for the year ended December 31, 2025, for which the same accounting policies,

critical accounting estimates and changes in accounting estimates have been applied with the exception of the newly

adopted accounting pronouncements outlined in section “Recently adopted accounting pronouncements”.

For purposes of the Group’s primary financial reporting outside the United States, the Group prepares its consolidated

financial statements in accordance with IFRS as endorsed by the EU. For purposes of the Group’s consolidated financial

statements prepared in accordance with IFRS as endorsed by the EU, the Group applies fair value hedge accounting for

portfolio hedges of interest rate risk (fair value macro hedges) in accordance with the EU carve out version of IAS 39. The

purpose of applying the EU carve out version of IAS 39 is to align the Group’s hedge accounting approach with its risk

management practice and the accounting practice of its major European peers. Under the EU carve out version of IAS 39

fair value macro hedge accounting may be applied to core deposits. In addition, the EU carve out version of IAS 39 hedge

ineffectiveness is only recognized when the revised estimate of the amount of cash flows in scheduled time buckets falls

below the original designated amount of that bucket. If the revised amount of cash flows in scheduled time buckets is

more than the original designated amount, then there is no hedge ineffectiveness. Under IFRS as issued by the IASB,

hedge accounting for fair value macro hedges cannot be applied to core deposits. In addition, under IFRS as issued by

the IASB hedge ineffectiveness arises for all fair value macro hedge accounting relationships whenever the revised

estimate of the amount of cash flows in scheduled time buckets is either more or less than the original designated

amount of that bucket. The EU carve out version of IAS 39 also removes the prohibition on identifying a benchmark risk

component in a financial instrument priced at sub–benchmark. This may arise when financial instruments carry a

negative spread such that the identified non–contractually specified risk component is larger than the interest carry on

the contract itself.

The application of the EU carve out version of IAS 39 had a negative impact of € 688 million on profit before tax and of

€ 496 million on profit after tax for the three-month period ended June 30, 2026, compared to a negative impact of

€ 535 million on profit before tax and of € 383 million on profit after tax for the three-month period ended June 30, 2025.

The application of the EU carve out version of IAS 39 had a positive impact of € 166 million on profit before tax and of

€ 119 million on profit after tax for the six-month period ended June 30, 2026, compared to a negative impact of

€ 144 million on profit before tax and of € 103 million on profit post taxes for the six-month period ended June 30, 2025.

The Group’s regulatory capital and ratios thereof are also reported on the basis of the EU carve out version of IAS 39. As

of June 30, 2026, the application of the EU carve out had a cumulative negative impact on the CET1 capital ratio of

about 53 basis points compared to a cumulative negative impact of about 75 basis points as of June 30, 2025.

The preparation of financial information under IFRS requires management to make estimates and assumptions for certain

categories of assets and liabilities. These estimates and assumptions affect the reported amounts of assets and liabilities

and disclosure of contingent assets and liabilities at the balance sheet date and the reported amounts of revenues and

expenses during the reporting period. Actual results could differ from management’s estimates, especially in relation to

potential impacts from tariffs or inflation and broader changes in the political and geopolitical environment (e.g., war in

Ukraine or Middle East conflict), and the results reported should not be regarded as necessarily indicative of results that
