Reclusive tycoon Pallonji Mistry controls Mumbai-headquartered engineering and construction giant, the 156-year-old Shapoorji Pallonji Group. The S.P. Group, run by Mistry's older son Shapoor, also owns Eureka Forbes, the country's leading brand of water purifiers. The family's biggest asset is an 18.4% stake in Tata Sons, holding outfit of the $103 billion (revenue) Tata Group, a conglomerate of 30 companies. After Mistry's younger son Cyrus was ousted as chairman of Tata Sons in October 2016, the two families have been at loggerheads. In September 2020, the Mistrys decided to sell their Tata Sons' stake saying "a separation of interests would best serve all stakeholder groups."
