ConocoPhillips (COP-N) announced today that it will separate into two companies, spinning off its refining arm. The move comes shortly after Marathon Oil (MRO-N) did the same with what is now Marathon Petroleum Corp (MPC-N). COP, the third largest oil company in the US, saw its shares rise as much as 7.5% before it closed the day up 1.6%. Though the deal does not require shareholder approval, today’s price fluctuation calls into question whether current investors will support the split.
