Shareholding pattern
Sir Dorabji Tata Trust and Sir Ratan Tata Trust are the two biggest shareholders of Tata Sons, with a combined stake of around 50%, while Pallonji Shapoorji Mistry was the largest individual shareholder. Pallonji's father, Shapoorji Pallonji Mistry was a prominent construction magnate who acquired a significant stake of Tata Sons in the 1930s initially from Framroze Edulji Dinshaw, and finally when JRD Tata's younger brother, Dorab, sold his shares in a fit of anger. Pallonji's shareholding was divided equally between his two sons, Shapoor Mistry and Cyrus Mistry, who died in September, 2022. Total equity shares: 404,146 (₹10 each)

Conversion to Private Ltd, and internal conflicts 
Natarajan Chandrasekaran took over as Chairman of Tata Sons on 21 February 2017. The company also undertook conversion from a public limited company to a private limited one in 2017; both these decisions were challenged in court by former executive chairman Cyrus Mistry. In December 2019, NCLAT declared the conversion, and by extension, Chandrasekaran's chairmanship, illegal and restored Mistry. On 10 January 2020, however, the Supreme Court stayed NCLAT's order; in response, Mistry filed a cross appeal in the court, seeking explanations for anomalies in the NCLAT. On 26 March 2021, the Supreme Court of India upheld Tata Sons' decision to sack Cyrus Mistry.
