Williams Closes $1.5B Acquisition of MountainWest Natural Gas Transmission and Storage Business
Williams has closed its acquisition of MountainWest Pipelines Holding Company from Southwest Gas Holdings, in a transaction including $1.07 billion of cash and $0.43 billion of assumed debt, for an enterprise value of $1.5 billion.
MountainWest comprises roughly 2,000-miles of interstate natural gas pipeline systems primarily located across Utah, Wyoming, and Colorado, totaling approximately 8 Bcf/d of transmission capacity. MountainWest also operates 56 Bcf of total storage capacity, including the Clay Basin underground storage reservoir, providing valuable service to western markets.
“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,” said Alan Armstrong, Williams president and chief executive officer.
“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,” added Armstrong.
“We are pleased to close the transaction with Williams, which is an important milestone in simplifying our corporate structure. This is a significant step toward returning Southwest Gas to its core regulated utility business of providing reliable, sustainable, and affordable energy to meet the expectations of customers and communities, while continuing to maximize its growth potential,” said Karen S. Haller, president and chief executive officer of Southwest Gas.
“We look forward to continuing to enhance our focus as we move forward with the planned spin-off of Centuri to create two focused industry leaders,” added Haller.
With the acquisition of MountainWest, Williams expands its infrastructure network and increases its business mix of FERC-regulated natural gas transmission and storage. The acquisition expands Williams’ services to key Rockies markets, including natural gas delivery into Salt Lake City and other demand markets not previously served by Williams.
