ICICI Bank Limited (the ‘Bank’) Report on Form 6-K

The Bank has made the below announcement to the Indian stock exchanges:

ICICI Bank Limited (the Bank) has been informed by ICICI Prudential Asset Management Company Limited (IPru AMC) and ICICI Venture Funds Management Company Limited (I-Ven) that their respective Boards of Directors have, at their meetings held on May 8, 2025, approved in-principle a proposal to transfer the private equity, venture capital and real estate fund management business of I-Ven to IPru AMC. I-Ven would continue to undertake certain advisory activities as well as manage certain residual funds. The cost of acquisition of the proposed transaction is not expected to be material in the context of IPru AMC’s financial position. The proposed transaction would enable the offering of an integrated full range of investment asset classes including private equity by IPru AMC.

The transaction would be subject to the receipt of requisite regulatory and other approvals, completion of other procedures and entering into the necessary agreements. The completion of procedures and business transfer would be intimated in due course of time. At March 31, 2025, the Bank held 51% of the equity share capital of IPru AMC and 100% of the equity share capital of I-Ven.

We request you to kindly take note of the same.
