Kumar Mangalam Birla and his family have raised their holding in Grasim Industries to 45.07%, buying 13,682,270 shares on the open market over 31 months, according to a filing disclosed on Monday, Sept. 28.
The promoter group now holds 306,711,893 shares. The filing measures the 2.01 percentage point increase from 43.06%, the level recorded in February 2024, and the purchases ran from Feb. 7 that year to Sept. 24, 2026.
Buying quietly and disclosing later is normal in India. Promoters, the term Indian markets use for founding families who control listed companies, must report cumulative acquisitions once they cross a threshold, which is why 31 months of purchases surface as a single announcement.
What Birla has been accumulating is a holding company as much as an operating one. Grasim is a flagship company of the Aditya Birla Group, a global leader in viscose staple fibre and India's largest chemicals producer, and it owns UltraTech Cement, the country's biggest cement maker, alongside 52.3% of Aditya Birla Capital, which houses the group's financial services businesses.
Buying Grasim therefore buys a slice of all of it.
Most of the stake sits in one vehicle. Birla Group Holdings Private Limited holds about 23%, after India's National Company Law Tribunal approved the merger of six family investment companies into it, among them Birla Family Investments and Birla TMT Holdings. Birla holds a further 0.26% in his own name, and his mother Rajashree, his wife Neerja and his three children Ananyashree, Advaitesha and Aryaman each appear separately on the register.
The company has been spending heavily while the family has been buying. Grasim's subsidiary Aditya Birla Renewables agreed in July to acquire Solenergi Power, owner of the Sprng Energy group, from Shell for an enterprise value of 172 billion rupees, about $1.8 billion. Grasim separately put 28.8 billion rupees into Aditya Birla Capital in June through a preferential share issue, lifting its holding there to 52.3%.
Grasim carries a market value of about 2.25 trillion rupees.
Birla is 59 and took over the group in 1995 at 28, after his father Aditya Vikram Birla died. He has spent three decades turning a textiles and commodities house into a conglomerate spanning cement, metals through Hindalco, chemicals, financial services, telecommunications through Vodafone Idea and fashion retail. Forbes ranks him among India's wealthiest people.
