I joined the Board of HDFC Bank in May 2021. My tenure on the Board saw momentous events like merger of the bank with HDFC Ltd that created a conglomerate under the Bank. This strategic initiative made HDFC Bank the second largest Bank in the country. Though, the benefits of merger are yet to fully fructify. Certain happenings and practices within the bank, that I have observed over last two years, are not in congruence with my personal Values and Ethics. This is the basis of my aforementioned decision. I confirm that there are no other material reasons for my resignation other than those stated above. I would like to express my sincere appreciation to the Board and senior management for their cooperation and support during my tenure. I express my gratitude to all the Independent Directors and Non-Executive Directors, who spared their valuable time and shouldered onerous responsibilities on the Board and its Committees. It has been a privilege to contribute to the growth and governance of the Bank. I observed great amount of energy and verve in the middle & junior levels of the organization, that should form the core of a reimaged organization. I also place on record my sincere appreciation for Secretarial, Compliance, Audit and Group oversight functions. Kindly instruct Company Secretary to take this letter on record and arrange to file the necessary intimations with the Registrar of Companies and other regulatory authorities as required under applicable law. I wish the Bank continued success in all its future endeavors. I remain, Part-time Chairman & Independent Director, HDFC Bank DIN: 01469375 Date 17/03/2026 Yours sincerely,
