Williams Companies has several parts, but they all add up to the delivery of energy and profits. Williams is engaged in gas marketing and the gathering, storing, and the processing of natural gas and natural gas liquids (NGLs). It also operates refineries, ethanol plants, and terminals. The company owns 60% of  Williams Partners which has gas pipeline operations in the Northwest, the Rockies, the Gulf Coast, and the East. The gas pipeline unit operates three major interstate pipeline companies, a midstream businesses in Canada, and an olefins business in the US. Williams had agreed to be bought by Energy Transfer Equity (ETE) but the deal fell through in 2016 when ETE backed out, citing the weak energy market.
