Williams, a firm providing infrastructure that safely delivers natural gas products, completed the acquisition of MountainWest Pipelines, an operator of natural gas pipeline systems, from Southwest Gas, a firm engaged in the business of purchasing, distributing, and transporting natural gas, for $1.5bn. “Our natural gas focused strategy is anchored in having the right assets in the right places to serve our nation’s growing demand for clean, affordable and abundant natural gas. This acquisition enhances our position in the western U.S. and is complementary to our current footprint, providing us with infrastructure for natural gas deliveries across key demand markets. With the acquisition now complete, we look forward to welcoming MountainWest employees to Williams and bringing value to our shareholders by delivering safe and reliable services to both Williams and MountainWest customers as we increase the utilization of our existing large scale platforms,” Alan Armstrong, Williams President and CEO.
