Filing of Form 20-F

ICICI Bank Limited (NYSE: IBN) filed its annual report in Form 20-F for the year ended March 31, 2025 (FY2025) on July 25, 2025, as required by United States securities regulations. The Form 20-F annual report includes the Bank’s consolidated financial statements under Indian GAAP and a reconciliation of consolidated profit after tax and net worth under Indian GAAP to net income and stockholders’ equity respectively, under U.S. GAAP, approved by the Audit Committee of the Board.

There are differences in the basis of accounting between U.S. GAAP and Indian GAAP primarily relating to allowance for loan losses, business combinations, consolidation, valuation of securities and derivatives, amortization of fees and costs, securitization, income taxes and fixed assets.

The consolidated profit after tax under Indian GAAP increased from Rs. 44,256 crore (US$ 5,180 million) in FY2024 to Rs. 51,029 crore (US$ 5,973 million) in FY2025. The consolidated net income under U.S. GAAP in FY2025 was Rs. 51,354 crore (US$ 6,011 million) compared to Rs. 61,376 crore (US$ 7,184 million) in FY2024.

Stockholders’ equity as per U.S. GAAP was Rs. 365,480 crore (US$ 42.8 billion) compared to the consolidated net worth as per Indian GAAP of Rs. 313,906 crore (US$ 36.7 billion) at March 31, 2025. The reconciliation of consolidated profit after tax and net worth under Indian GAAP to net income and stockholders’ equity under U.S. GAAP is explained in note 21 of the consolidated financial statements of the Bank in Form 20-F.

Pursuant to its issuance and listing of securities in the United States under registration statements filed with the Securities and Exchange Commission, ICICI Bank files annual report in Form 20-F with the SEC as required by U.S. securities laws and regulations. ICICI Bank in its annual report in Form 20-F includes consolidated financial statements under Indian GAAP, with a reconciliation of profit after tax and net worth under Indian GAAP to net income and stockholders' equity respectively, under U.S. GAAP and a description of differences between Indian GAAP and U.S. GAAP.
