Kekst CNC is providing global strategic communications and crisis support to Adani Group, the India-based conglomerate that has been accused of accounting fraud and stock market manipulation by Hindenburg Research.

The company has denied Hindenburg’s allegations and has issued a more than 400-page rebuttal to the charges lodged by the New York-based short seller.

Adani Group, which operates India’s ports, runs its power transmission lines, stores its grain and produces its cement, ranks among the country’s top ten non-financial firms.

Gautam Adani, who was the world’s third richest man and the self-proclaimed Rockefeller of India, has lost tens of billions in wealth since the release of Hindenburg’s report on Jan. 24.

The Economist editorialized on Feb. 9 that “the humbling of Gautam Adani is a test for Indian capitalism.” It also is a political embarrassment for India’s prime minister Narendra Modi, who has close ties to Adani.

Adani Group reportedly has hired New York law firm Wachtell, Lipton, Rosen & Katz to help stem the crisis.

Wachtell is “among the most sought-after advisers by besieged corporate boards at some of the largest US companies trying to fend off activist investors or hostile takeovers," according to the Financial Times.
