Through this exercise, the promoters aim to eventually hold stakes of 64-68% each across group companies, ET reported in August. The promoter group raised its stake in Adani Enterprises, Adani Power and Adani Green Energy last quarter.

According to the average price of shares during the quarter, promoters are likely to have spent about ?16,134.31 crore on raising their holdings in the three companies.
