Marathon Oil Corp (MRO.N) said it will split off its refinery and pipeline operations into a stand-alone company, pushing its shares up 9 percent. The move, which will take effect on June 30, 2011, will create the fifth-largest U.S. refiner and revives a plan the company had shelved in December 2008, when the financial crisis hit commodity markets. Analysts and investors have long called on the Houston-based company to split into two to unlock value that Wall Street was overlooking.
