BENGALURU, March 2 (Reuters) - U.S. boutique investment firm GQG Partners has bought shares worth $1.87 billion in four Adani group companies, marking the first major investment in the Indian conglomerate since a short-seller's critical report sparked a stock rout. U.S-based, Australia-listed GQG has, through block deals, bought shares worth 154.46 billion rupees in four Adani group companies, including the conglomerate's flagship firm Adani Enterprises (ADEL.NS), a regulatory filing showed. GQG took a 3.4% stake in Adani Enterprises for about $662 million, 4.1% in Adani Ports for $640 million, 2.5% in Adani Transmission for $230 million, and a 3.5% stake in Adani Green Energy for $340 million. "This transaction marks the continued confidence of global investors in the governance, management practices and the growth of Adani Portfolio of companies," said Adani Group CFO Jugeshinder Singh. In the run-up to the announcement, Adani group shares rallied, with Adani Enterprises climbing nearly 35% over the last three sessions, Adani Ports 11% and Adani Green Energy 16%.
