The Shapoorji Pallonji (SP) Group, the second-largest shareholder in Tata Sons, has publicly supported a potential listing of the holding company for India's expansive Tata conglomerate. In a statement issued on Friday, September 18, 2026, the group declared, "Look forward to working closely and constructively with Tata Sons towards listing." This endorsement suggests a shift in the ongoing power struggle and could reshape the ownership dynamics of one of India's most prominent business groups.

This development comes amidst heightened scrutiny on Tata Sons regarding its listing status. The Reserve Bank of India's (RBI) recent decision to not relax listing rules for the Tata Group's holding company is seen as a victory for Shapoor Mistry, head of the debt-laden Shapoorji Pallonji Group. Mistry had previously sought a listing of Tata Sons Pvt. to unlock value from his group's 18.4% stake, as outlined in an open letter to the regulator months prior to the RBI's decision.

The SP Group, facing substantial debt, had reportedly proposed an alternative to a public listing, offering to sell a 2-3% stake back to Tata Sons for $300 million (₹25,000 crore), which would value the holding company at $99.6 billion (₹8.3 trillion). This proposal was presented to the Tata Sons board by Noel Tata, chairman of Tata Trusts. However, with the RBI mandate for listing, the SP Group's public support for an IPO indicates a potential alignment with the regulatory direction, even though they previously viewed an IPO as a complex and potentially discounted valuation process compared to a direct sale.

The SP Group's ownership of an 18.38% stake in Tata Sons dates back to 1965. The group's financial challenges, including a reported $7.2 billion (₹60,000 crore) in debt, have made monetizing their stake critical. The conversion of Tata Sons into a private limited company after Cyrus Mistry's ouster in 2016 complicated share transfers, making an IPO or a structured sale crucial for the SP Group to address its financial obligations. The support for listing could signify a pathway for the SP Group to finally realize value from its significant holding.
