Shares in Icahn Enterprises, the conglomerate of billionaire investor Carl Icahn, fell by as much as 20 percent in morning trading on 10 May after a regulatory filing revealed that the US Attorney’s office for the Southern District of New York had contacted the company seeking information about its corporate governance, capitalization, securities offerings, dividends, valuation, marketing materials, due diligence, and other matters. The filing followed the taking of a short position by noted short-seller Hindenburg Research, which alleged inflated asset valuations and other concerns about the company’s operations.
