What was filed
Kotak Mahindra Bank told the exchanges that Mr. Manish Kothari, Group President and Head – Commercial Bank and a Senior Management Personnel of the bank, has tendered his resignation, with his last working day the close of 30 September 2026. In his letter, Kothari said he was stepping down for personal reasons after thirty-one years at the firm, to pursue a journey outside Kotak, possibly an entrepreneurial one.
A planned transition
The bank framed the departure as orderly. Per the filing, it has initiated a planned transition and has already integrated the Commercial Bank portfolio handled by Kothari into its Retail and Institutional business segments. Kothari's letter describes working over several months with the whole-time directors and business heads to hand over the businesses he led.
Why it matters to a holder
This is a senior-management change disclosure — leadership continuity, not financial results, none of which the filing addresses. The notable structural detail is that the Commercial Bank vertical is not being handed to a single successor but absorbed into the bank's existing Retail and Institutional segments, per the filing.
