CVR Energy (CVI +4.4%) jumps after Carl Icahn issues an open letter blasting a recent statement made by the company regarding Icahn's $30/share tender offer as "disingenuous and misleading." Icahn says he plans to "conduct a full and open process" to sell CVR if he manages to gain control of the company, but says he will drop his bid if his offer doesn't leave him with a majority stake by March 23.
