Hindenburg's report, which was behind a market rout of more than $100 billion in India's Adani Group earlier this year, alleges payments firm led by Twitter co-founder overstated its user numbers and understated its customer acquisition costs.
Gautam Adani, who saw $100 billion rout in shares of his listed firms, says his conglomerate has "impeccable track record" of fulfilling debt obligations. Meanwhile, Citigroup stops accepting securities of his firms as collateral for margin loans.
The Adani Group is led by Gautam Adani, the third richest man in the world (now the fourth). It has lost billions in market value in two days, all due to a report by Hindenburg Research, specialising in “forensic financial research”.
