India’s Adani Group issued a detailed riposte on Sunday to a Hindenburg Research report that sparked a $48 billion rout in its stocks, saying it complies with all local laws and had made the necessary regulatory disclosures.

The conglomerate led by Asia’s richest man, the Indian billionaire Gautam Adani, said last week’s Hindenburg report was intended to enable the US-based short seller to book gains, without citing evidence.

For 60-year-old Adani, the stock market meltdown has been a dramatic setback for a school dropout who rose swiftly in recent years to become the world’s third richest man, before slipping last week to rank seventh on the Forbes rich list.

Adani Group’s response comes as its flagship company, Adani Enterprises, pushes ahead with a $2.5bn share sale. This has been overshadowed by Hindenburg’s report, which flagged concerns about debt levels and the use of tax havens.

“All transactions entered into by us with entities who qualify as ‘related parties’ under Indian laws and accounting standards have been duly disclosed by us,” Adani said in the 413-page response issued late on Sunday.

“This is rife with conflict of interest and intended only to create a false market in securities to enable Hindenburg, an admitted short seller, to book massive financial gain through wrongful means at the cost of countless investors,” it added.

Hindenburg said on its website Adani’s “response largely confirmed our findings and ignored our key questions”. It reiterated that it was short on the Adani group through US-traded bonds and non-Indian-traded derivative instruments.

Its report had questioned how the Adani Group has used offshore entities in tax havens such as Mauritius and the Caribbean islands, adding that certain offshore funds and shell companies “surreptitiously” own stock in Adani’s listed firms.

The research report, Adani said, made “misleading claims around offshore entities” without any evidence whatsoever.

Hindenburg said it “found Adanis lack of direct and transparent answers” on the allegations of use of offshore entities “telling”.

Adani said on Thursday that it is considering taking action against Hindenburg, which responded on the same day by saying it would welcome such a move.

Hindenburg’s report also said five of seven key listed Adani companies have reported current ratios, a measure of liquid assets minus near-term liabilities, of below 1 which it said suggested “a heightened short-term liquidity risk”.

It said key listed Adani companies had “substantial debt” which has put the entire group on a “precarious financial footing” and that shares in seven Adani listed companies have an 85 per cent downside due to what it called “sky-high valuations”.

Adani’s response stated that over the past decade, its group companies have “consistently de-levered”.

Defending its practice on pledging shares of its promoters — or key shareholders — the Adani Group said that raising financing against shares as collateral was common practice globally and loans are given by large institutions and banks on the back of thorough credit analysis.

The group added there is a robust disclosure system in place in India and its promoter pledge positions across portfolio companies had dropped from more than 50pc in March 2020 in some listed stocks, to less than 20pc in December 2022.

‘Sail through’

The Hindenburg report, and its fallout is seen as one of the biggest career challenges to face the billionaire, whose business interests range from ports, airports, mining and power to media and cement.

Adani’s response included more than 350 pages of annexes that included snippets from annual reports, public disclosures and earlier court rulings.

Hindenburg, Adani said, had sought answers to 88 questions in its report, but 65 of them were related to matters that have been disclosed by Adani portfolio companies in annual reports.

The rest, Adani said, relate to public shareholders and third parties, and some were “baseless allegations based on imaginary fact patterns”.

Hindenburg said “Adani failed to specifically answer 62 of our 88 questions.”

Hindenburg is known for having shorted electric truck maker Nikola Corp and Twitter.

Adani also responded to allegations by Hindenburg relating to the company’s auditors, saying “all these auditors who have been engaged by us have been duly certified and qualified by the relevant statutory bodies.”

Its response comes just hours ahead of India market opening, when the $2.5bn secondary share sale begins its second day of subscription. Friday’s plunge took Adani Enterprises shares below the issue price, raising doubts about its success.

In a separate statement on Sunday, Adani Group’s chief financial officer Jugeshinder Singh said it is focused on the share sale and is confident it will succeed. He also said its anchor investors have shown faith and remain invested.

“We are confident the FPO (follow-on public offering) will also sail through,” he said.
