May 12 (Bloomberg) -- Citigroup Inc. Chief Executive Officer Vikram Pandit faces an ``impossible feat'' in turning around the biggest U.S. bank as it faces ``seismic'' costs to restructure, Oppenheimer & Co. analyst Meredith Whitney said.
Citigroup will be forced to announce the sale of major businesses toward the end of this year or in early 2009, Whitney, who recommends investors sell the shares, said in a Bloomberg TV interview today. One of the units could be Banamex, the company's Mexican branch, she said.
