Nairobi — Two Middle Eastern wealth funds have invested up to $1 billion in Indian energy company Adani Energy Solutions' share sale after a one and a half-year share offering halt.

According to reports, the two investment companies, which include Abu Dhabi Investment Authority and Qatar Investment Authority, executed the deal on Tuesday, triggering a 7 percent stock increase.

In February of last year, U.S. Hindenburg Research prompted a call-off of a $2.5 billion share offering after claiming that the Adani group led by the group's CEO was involved in stock manipulation and inappropriate use of offshore tax havens.

Furthermore, Hindenburg claimed that Adani companies had also taken on substantial debt, including pledging shares of their inflated stock for loans, consequently positioning the entire group on "precarious financial footing".

However, in a statement, Adani groups led by the group's chairperson and CEO Gautam Adani strongly refuted these claims.

However, following the report, the group significantly plummeted its borrowing by more than 3.5 percent last year.

"Today we reveal the findings of our 2-year investigation, presenting evidence that the INR 17.8 trillion (U.S. $218 billion) Indian conglomerate Adani Group has engaged in a brazen stock manipulation and accounting fraud scheme over decades," the report from Hindenburg stated.

According to reports, as of Tuesday, the company's share sale was for $700 million, with an additional option for a further $300 million.

The company's stock had significantly plummeted by 60% below where it was before the organization was accused by Hindenburg Research.

The allegations from Hindenburg triggered a sell-off of the group's stock worth over $100 billion, and despite the pronounced recovery of the company's shares, the new deal will be pivotal in attracting investors' trust backing.
