Shapoorji Pallonji Group has pushed for listing of Tata Sons, the holding entity of Tata Group, and expects RBI to act upon the deadline, NDTV-Profit reported. RBI's "upper layer" classification for Tata Sons, issued in 2022, required the company to be mandatorily listed by September 2025. Notably, Tata Sons' listing will provide SP Group an opportunity to liquidate its stake.
