Gautam Adani, the billionaire chair of Indian conglomerate Adani Group and one of the world's richest people, has been indicted in New York over his role in a $265 million bribery scheme, according to U.S. prosecutors.
U.S authorities said Adani and seven other defendants, including his nephew Sagar Adani, agreed to pay the bribes to Indian government officials to obtain contracts expected to yield $2 billion of profit over 20 years, and develop India's largest solar power plant project.
A judge has issued arrest warrants for Gautam Adani and Sagar Adani and prosecutors plan to hand those warrants to foreign law enforcement, court records show.
Prosecutors also said the Adanis and another executive at Adani Green Energy, former CEO Vneet Jaain, raised more than $3 billion in loans and bonds by hiding their corruption from lenders and investors.
Gautam Adani, Sagar Adani and Jaain were charged with securities fraud, securities fraud conspiracy and wire fraud conspiracy, and the Adanis were also charged in a U.S. Securities and Exchange Commission civil case.
Fallout for the Adani empire, which was rocked by a short-seller attack in February 2023, was immediate with shares in conglomerate's listed companies stocks tumbling between 10% and 20%.
Adani Green Energy also cancelled plans on Thursday to raise $600 million in U.S. dollar-denominated bonds. The bond had been priced but was pulled following the news.
Adani dollar bonds slumped in Asian trading, with prices down between 3-5c on bonds for Adani Ports and Special Economic Zone. The falls were the largest since the Adani Group came under a short-seller attack in February 2023.
According to an indictment, some conspirators referred privately to Gautam Adani with the code names "Numero uno" and "the big man," while Sagar Adani allegedly used his cellphone to track specifics about the bribes.
The Adani Group has not responded to requests for comment.
Gautam Adani, Sagar Adani and Jaain were charged with securities fraud, securities fraud conspiracy and wire fraud conspiracy, and the Adanis were also charged in a U.S. Securities and Exchange Commission civil case.
Five other defendants were charged with conspiring to violate the Foreign Corrupt Practices Act, a U.S. anti-bribery law, and four were charged with conspiring to obstruct justice.
None of the defendants is in custody, a spokesperson for U.S. Attorney Breon Peace in Brooklyn said. Gautam Adani is believed to be in India.
Shares in GQG Partners, an Australia-listed investment firm that is a major Adani backer, slid 20%. The decline was the stock's largest one-day fall since it listed three years ago.
GQG last year bought 3.4% of Adani Enterprises - the group's flagship firm, 4.1% of Adani Ports and Special Economic Zone, 2.5% of Adani Transmission and 3.5% of Adani Green Energy. It said in a statement that it was monitoring the charges.
Gautam Adani, 62, is worth $69.8 billion according to Forbes magazine. He is one of the few billionaires formally accused in the United States of criminal wrongdoing.
