SCRUTINIZERS’ REPORT

ICICI Bank Tower,

Near Chakli Circle,

Vadodara - 390 007

Dear Sir,

Sub.: Scrutinizer’s Report on Results of Postal Ballot through electronic voting (remote e-voting) process

I, Alwyn D’Souza (Membership no. FCS No.: 5559/ COP No. 5137) of Alwyn D’Souza & Co, Company Secretaries have been appointed as the Scrutinizer by the Board of Directors of ICICI Bank Limited (“Bank”) at its meeting held on January 17, 2026 for the purpose of scrutinizing the e-voting process for the Postal Ballot through electronic voting (‘remote e-voting’) conducted by the Bank in respect of the following Special Resolution:

Appointment of Ms. Vijayalakshmi Iyer (DIN: 05242960) as an Independent Director with effect from December 1, 2025.

The Bank had availed the remote e-voting facility offered by KFin Technologies Limited (‘KFintech’) for conducting remote e-voting by the shareholders of the Bank.

The Postal Ballot was held in compliance with the provisions of Section 110 read with Section 108 and all other applicable provisions, if any, of the Companies Act, 2013, (including any statutory amendment(s), modification(s), variation(s) or re-enactment(s) thereof for the time being in force) (“the Act”), read with Rule 20 and Rule 22 of the Companies (Management and Administration) Rules, 2014, as amended from time to time (“Rules”), read with General Circular No. Circular No. 14/2020 dated April 8, 2020; General Circular No. 17/2020 dated April 13, 2020 and other relevant circulars,

including General Circular No. 03/2025 dated September 22, 2025 and other circulars issued by the Ministry of Corporate Affairs, Government of India (hereinafter collectively referred to as (“MCA Circulars”), Regulation 44 of the Securities and Exchange Board of India (Listing Obligations and Disclosure Requirements) Regulations, 2015 (“Listing Regulations”), as amended, and Secretarial Standard-2 on General Meetings issued by the Institute of Company Secretaries of India and any other applicable laws, rules and regulations (including any statutory amendment(s), modification(s), variation(s) or re-enactment(s) thereof, for the time being in force) for seeking assent/dissent on the Special Resolution as set out in the Postal Ballot Notice (“Notice”).

In compliance with Regulation 44 of the Listing Regulations and pursuant to the provisions of Sections 108 and 110 of the Act read with the rules framed thereunder and the MCA Circulars, the Bank had sent the Notice in electronic form only and had extended only remote e-voting facility for its Members, to enable them to cast their votes electronically instead of submitting the Postal Ballot forms. Accordingly, the hard copy of the Notice along with the Postal Ballot forms and pre-paid business envelope was not sent to the Members for this Postal Ballot.

The Bank had on January 20, 2026 sent the Notice along with statement setting out material facts under Section 102 of the Act in respect of the above mentioned resolution, in electronic form only to those Members whose name appear in the Register of Members/Register of Beneficial Owners as received from the Depositories i.e. National Securities Depository Limited (‘NSDL’)/ Central Depository Services (India) Limited (‘CDSL’) as on Monday, January 19, 2026 (“Cut-Off date”) and who already had their e-mail address registered with KFintech (Registrar & Share Transfer Agent of the Bank for equity shares)/Bank/Depositories, in accordance with the provisions of the Act read with the Rules made thereunder and MCA Circulars.

In connection with the dispatch of the Notice to Holders of American Depository Shares (“ADS”), the cut-off date was January 30, 2026 for determining the registered ADS holders entitled to participate/vote at the Postal Ballot.

As stated in Sub-rule 3 of Rule 22 of Companies (Management and Administration) Rules, 2014, as amended, a Public Notice with regards to Bank’s Postal Ballot Notice was published in Financial Express (all editions), Business Standard (all editions), Vadodara Samachar and Indian Express (Vadodara edition) on January 21, 2026 informing about the completion of dispatch of Notices, requisite information for registering email IDs and queries pertaining to remote e-voting to the Members along with other related matters mentioned therein.

The shareholders of the Bank holding shares as on the Cut-off Date were entitled to vote on the resolution as contained in the Notice. The remote e-voting period commenced on Tuesday, January 27, 2026 at 9:00 a.m. IST and ended on Wednesday, February 25, 2026 at 5:00 p.m. IST. The remote e-voting module was disabled thereafter.

After the time fixed for closing of the e-voting, the votes were unblocked on Wednesday, February 25, 2026 at 5:01 p.m IST in the presence of two witnesses who are not in the employment of the Bank, on the e-voting website of KFintech at https://evoting.kfintech.com and a final electronic report was generated by me. I have diligently scrutinized and reviewed the votes cast through remote e-voting based on the basis of abovementioned data and have maintained a register in which necessary entries have been made in accordance with the Rules, as amended.

The data for the purpose of verification of the number of shares was taken as of Monday, January 19, 2026 which was the relevant date (cut-off date), fixed for determining voting rights of the Members entitled to participate in the voting process.

The voting rights of members were in proportion to their share of the paid-up equity share capital of the Bank as on the Cut-off date and as per the Register of Members of the Bank/Register of Beneficial Owners as received from the Depositories .

In accordance with the approval of Ministry of Finance, Department of Economic Affair the Deposit Agreement dated March 31, 2000 was executed by the Bank with Deutsche Bank Trust Company Americas (“DBTCA”) wherein the voting rights on American Depository Receipts (“ADRs”) could be exercised in accordance with directions of the Bank’s Board of Directors. However, effective January 2, 2026, the Deposit Agreement has been amended to provide voting rights to the ADR holders subject to them demonstrating compliance with the applicable laws of Republic of India (including but not limited to Section 12B of the Banking Regulation Act, 1949 as amended or replaced from time to time). Accordingly, DBTCA exercised the voting rights as instructed by the ADR Holders of the Bank. The votes so casted by DBTCA have been considered while computing the voting results.

I would like to mention that Shareholders who have split their votes into Assent as well as Dissent in respect of each DP ID/Client ID or Folio No., while their votes are taken as cast, they have been counted only once and has been mentioned under the head Assent.

The Management of the Bank is responsible to ensure the compliance with the requirements of the relevant provisions of the Act and Rules made thereunder and the various circulars issued by the Ministry of Corporate Affairs, Government of India and Listing Regulations relating to remote e-voting on the Resolution contained in the Notice.

My responsibility as the Scrutinizer for the Postal Ballot through remote e-voting is restricted to prepare a Scrutinizer’s Report of the votes cast “IN FAVOUR” and “AGAINST” on the business stated in the Notice based on the reports generated from the e-voting system provided by the KFintech.

The results of the Postal Ballot through remote e-voting process in respect to the resolution contained in the Notice is as under:
