Pursuant to the issuance and listing of our securities in the United States under registration statements filed with the United States Securities and Exchange Commission (“SEC”), we file annual reports on Form 20-F which must include financial statements prepared under generally accepted accounting principles in the United States (“U.S. GAAP”), or financial statements prepared according to a comprehensive body of accounting principles with a reconciliation of net income and stockholders’ equity to U.S. GAAP. When we first listed our securities in the United States, Indian GAAP was not considered a comprehensive body of accounting principles under the United States securities laws and regulations. However, pursuant to a significant expansion of Indian accounting standards, Indian GAAP constitutes a comprehensive body of accounting principles. Accordingly, we have included in this annual report, as in the annual reports for fiscal years 2024 through 2026, consolidated financial statements prepared according to Indian GAAP, with a reconciliation of net income and stockholders’ equity to U.S. GAAP and a description of significant differences between Indian GAAP and U.S. GAAP.

Our annual report prepared and distributed to our shareholders under Indian law and regulations include unconsolidated Indian GAAP financial statements, management’s discussion and analysis of the Bank’s results of operations and financial condition based on the Bank’s unconsolidated Indian GAAP financial statements and our consolidated Indian GAAP financial statements.
