Adani-Hindenburg Episode 2023
In January 2023, US short-seller Hindenburg Research published a report alleging stock price manipulation and accounting fraud at Adani Group entities, triggering the largest single-week wealth destruction by an Indian conglomerate and prompting a SEBI investigation into the allegations.
Hindenburg Research, a US-based short seller known for adversarial investigative reports on companies it bets against, released a 106-page report on 24 January 2023 titled 'Adani Group: How The World's 3rd Richest Man Is Pulling The Largest Con In Corporate History.' The report alleged that the Adani Group, led by Gautam Adani, had engaged in stock price manipulation through offshore shell entities in Mauritius and other jurisdictions, that debt levels were unsustainably high at several group companies, and that key listed entities had questionable related-party transactions with privately held group entities.
Adani Group shares had appreciated enormously in the years preceding the report, making Gautam Adani one of the wealthiest individuals in the world. The seven listed Adani companies commanded a combined market capitalisation of roughly 19 trillion rupees at their peak. In the four trading days following the Hindenburg report, this combined market cap fell by approximately 10 to 12 trillion rupees — one of the fastest destructions of conglomerate market value in financial history.
Adani Group published a detailed 413-page rebuttal calling the Hindenburg report a calculated attack on India and its institutions. The group emphasised its compliance with all disclosure regulations, the strategic importance of its infrastructure assets, and what it described as factual inaccuracies in the short-seller's claims. A planned 20,000 crore rupee follow-on public offering, which was already subscribed on listing, was later withdrawn and refunded to protect investor interests.
SEBI launched an investigation into the allegations regarding share price manipulation and minimum public shareholding compliance. The Supreme Court of India formed an expert committee headed by former Chief Justice AM Sapre to review SEBI's investigation timelines and the adequacy of India's regulatory framework. The committee's final report noted that no regulatory failure had been definitively established and that SEBI's probe was still ongoing at the time of the committee's submission.
The episode sparked a broader debate in India about the adequacy of disclosure requirements for complex conglomerates, the rights of short sellers to publish research, and the mechanisms for protecting retail investors caught between a powerful corporate group and an adversarial foreign institution. It also caused Indian regulators to revisit rules around beneficial ownership disclosure and foreign investor identification.
