About Phillips 66
The Phillips 66 Company is an American multinational energy company headquartered in Westchase, Houston, Texas. Its name, dating back to 1927 as a trademark of the Phillips Petroleum Company, assisted in establishing the newly reconfigured Phillips 66. The company today was formed ten years after Phillips merged with Conoco to form ConocoPhillips. The merged company spun off its refining, chemical, and retail assets – known in the oil industry as downstream operations – into a new company bearing the Phillips 66 name. It began trading on the New York Stock Exchange on May 1, 2012, under the ticker PSX.
