AU Small Finance Bank (AU SFB) told stock exchanges on Thursday, May 7, 2026 that it has received approval from the Reserve Bank of India (RBI) for Kotak Mahindra Bank Limited to acquire up to 9.99% in the bank. The approval allows Kotak Mahindra Bank, along with its subsidiaries and funds or schemes managed by its subsidiaries, collectively referred to as the “Kotak Mahindra Group”, to build an aggregate holding of up to 9.99% of AU SFB’s paid-up share capital or voting rights. The RBI’s nod was dated May 6, 2026, and AU SFB said the exchange filing was released during market hours on May 7. The disclosure provided regulatory clarity on how far the Kotak group can increase exposure.

Conditions attached to the nod

AU SFB said the approval is subject to compliance with multiple laws and regulations. These include the Banking Regulation Act, 1949 and RBI directions issued under it. The approval is also linked to the provisions of the Foreign Exchange Management Act (FEMA), 1999, and applicable Securities and Exchange Board of India (SEBI) regulations. The filing additionally referenced “other relevant statutes, regulations and guidelines”, indicating that the stake build-up must remain within broader regulatory guardrails.
