Marathon Oil Corp (MRO.N) said it would split off its refinery and pipeline operations into a stand-alone company in an effort to drive up its market value, and its shares rose 6 percent. The move, to take effect on June 30, would turn the fifth-largest U.S. refiner, reviving 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, with a market capitalization of $43 billion, to split into two to unlock value that Wall Street was overlooking.
