The Reserve Bank of India has rejected Tata Sons’ application to surrender its core investment company registration, requiring the holding company to comply with the framework for upper-layer non-bank financial companies, which includes a mandatory listing requirement. Tata Sons applied in March 2024 after becoming debt-free and argued that it should remain privately held. The decision could give investors a clearer market reference for roughly ₹1.2 lakh crore ($12.5 billion) of Tata Sons holdings spread across seven listed Tata companies, which collectively own between 11.6% and 11.92% of the holding company. Based on a valuation of about ₹10 lakh crore, Tata Steel and the demerged Tata Motors Passenger Vehicles unit each hold stakes worth roughly ₹30,600 crore, while Tata Chemicals’ holding is valued at about ₹25,300 crore. The listed companies have not indicated that they will sell their stakes in a potential IPO. Tata Sons faces a possible offering or court challenge, while the listing could require changes to its cross-holdings, governance and asset allocation. The company’s ownership remains layered, with Tata Trusts holding control and the Shapoorji Pallonji Group owning 18.37%.
