The last hurdle for CME is a group of dissident Nymex shareholders that have been pushing to increase the deal above $115 a share. The original value of the transaction was around $11 billion, but the stock of both companies has quickly deteriorated since January due to conditions in the financial markets.
Dissident shareholders such as Cataldo Capozza also have lawsuits pending against the deal. Capozza said he will try to block the deal in its current state and is also considering a move to remove the energy exchange's CEO, James Newsome. - Maria Woehr
