Sub: HDFC Bank Limited - Scrutinizer’s Report on Postal Ballot (E-voting) Results

I, B Narasimhan, Proprietor of BN & Associates, Company Secretaries, had been appointed as a Scrutinizer by the Board of Directors of HDFC Bank Limited (hereinafter referred to as the “Bank”) at its meeting held on March 26, 2026 to scrutinize the e-voting process in a fair and transparent manner in respect of the resolution as stated in the Postal Ballot Notice dated March 26, 2026 (the “Postal Ballot Notice”).

In compliance with the provisions of Sections 108 and 110 of the Companies Act, 2013 (the “Act”) read with Rule 20 and 22 of the Companies (Management and Administration) Rules, 2014, including any statutory amendment(s), modification(s), variation(s) or re-enactment(s) thereto, for the time being in force and in compliance with the applicable guidelines / circulars / rules issued by the Ministry of Corporate Affairs (“MCA”) inter alia including General Circular No. 03/2025 dated September 22, 2025 read with other relevant circulars issued by MCA (“MCA Circulars”) from time to time, Regulation 44 of the Securities and Exchange Board of India (Listing Obligations and Disclosure Requirements) Regulations, 2015 (“SEBI Listing Regulations”), Secretarial Standard on General Meetings (“SS-2”) issued by the Institute of Company Secretaries of India, and other applicable laws and regulations, if any, the following special business mentioned in the Postal Ballot Notice was proposed to be passed by the Members of the Bank by way of Postal Ballot through voting by electronic means (“remote e-voting”) only. The Bank had, accordingly, provided facility of remote e-voting to all Members of the Bank to enable them to cast their votes electronically on the special business mentioned in the Notice.

The Bank had engaged the services of National Securities Depository Limited, as the Electronic Voting Service Provider (“NSDL”) who had made necessary arrangements to facilitate remote e-voting by the shareholders of the Bank on their website www.evoting.nsdl.com. Datamatics Business Solutions Limited is the Registrar and Share Transfer Agent for the Bank (the “RTA”).

The Bank had sent the Postal Ballot Notice including all the requisite information required by the shareholders to cast their vote(s), in electronic form only to those Members who had registered their e-mail addresses with RTA / Depository Participants, as on Friday, March 20, 2026 (being the cut-off date specified for the purpose of identifying eligibility of Members to vote on the Postal Ballot). The communication of the assent or dissent of the Members was sought through the remote e-voting system only.

The Bank and NSDL had uploaded the Postal Ballot Notice together with the explanatory statement on their respective websites viz. www.hdfc.bank.in and www.evoting.nsdl.com and Electronic Voting Event Number “138927” (’EVEN’) was generated for casting the votes through the e-voting mode. The Bank and NSDL have complied with all the necessary formalities specified under the Act, the Rules framed thereunder and the MCA Circulars issued in this regard.

The Management of the Bank is responsible for ensuring compliance with the requirements of the Act and the Rules made thereunder and SEBI Listing Regulations relating to the items placed for approval of the Members through Postal Ballot by e-voting. My responsibility as the Scrutinizer of the voting process (through e-voting), was restricted to scrutinizing the remote e-voting process, in a fair and transparent manner and to prepare a Scrutinizer’s Report on the votes cast in favour or against the resolutions stated in the Postal Ballot Notice, based on the data generated from the e-voting system provided by NSDL.

I report that the Postal Ballot Notice was sent on Friday, March 27, 2026 through e-mail to 38,97,422 Members whose e-mail addresses were registered with the RTA /Depositories. The total Number of Members as on the Cut-off date were 40,38,941.

The e-voting period commenced on Saturday, March 28, 2026 at 10:00 a.m. (IST) and ended on Sunday, April 26, 2026 at 5.00 p.m. (IST). The Bank also published an advertisement in newspapers having nation-wide circulation on Saturday March 28, 2026 viz. in “Business Standard”, English Newspaper (all editions), and in “Free Press Journal”, Marathi edition Newspaper (Mumbai edition) providing requisite information as required under Rules framed under the Act and MCA Circulars.
