Indian billionaire Gautam Adani's indictment by U.S. authorities for his alleged role in a $265 million bribery scheme has sent shockwaves through his eponymous ports-to-soybeans conglomerate. The Adani Group denies the allegations.

Adani, 62, one of Asia’s richest men, was thrust into the spotlight last week when U.S. prosecutors in New York charged him and seven of his associates with securities fraud.

Since the bribery indictment last week, Indian billionaire Gautam Adani's net worth has tumbled almost $16 billion to about $54 billion currently, according to Forbes real-time data. The group is also facing a backlash from investors and business partners.
