Phillips 66

RANK143

It was a tumultuous year for Phillips 66, the Houston-based energy company. As lockdowns rippled around the globe, demand for transport fuels for cars and planes plunged, while losses mounted industrywide. Phillips 66 was no exception: The company lost $4 billion for the full year on a 40% drop in revenues. Like its peers, the company cut operating costs and slashed capital spending. The start of 2021, too, was rocky, as a crippling February storm in Texas hit operations in the state from refineries to pipelines.
