Williams Buys Momentum Midstream for $5.5B

Williams Companies has finalized a substantial acquisition, agreeing to purchase Momentum Midstream for a total consideration of up to $5.5 billion. This strategic move significantly bolsters Williams' presence in the vital Haynesville shale region, a critical artery for U.S. natural gas exports. The transaction marks a significant exit for energy-focused private equity firm EnCap Flatrock Midstream, which had backed Momentum Midstream.

The deal's financial structure involves approximately $3.5 billion in cash and assumed debt, complemented by roughly $2 billion in Williams stock. This acquisition is among the largest undertaken by Williams, underscoring its commitment to expanding its midstream infrastructure network. The Haynesville basin is experiencing heightened activity due to the insatiable demand from the burgeoning U.S. liquefied natural gas (LNG) export market, making assets in this region highly coveted.

Momentum Midstream, headquartered in Houston, operates an extensive network of approximately 4,000 miles of natural gas pipelines. This infrastructure boasts a daily transportation capacity of around 6 billion cubic feet, connecting prolific production areas in East Texas and northern Louisiana to key demand centers, including LNG export terminals, power generation facilities, and industrial consumers along the U.S. Gulf Coast. The integration of these assets is expected to enhance Williams' logistical capabilities significantly.

The acquisition underscores a broader industry trend where established midstream operators are increasingly turning to strategic acquisitions to expand capacity. With new pipeline construction facing considerable regulatory hurdles and lengthy permitting processes, acquiring existing, operational networks presents a more efficient pathway to growth. This approach is particularly attractive as the U.S. LNG sector continues its rapid expansion, with projections indicating a substantial increase in export capacity as new terminals become operational throughout the decade.

In conjunction with the acquisition, Williams announced plans for an additional $1.5 billion investment in infrastructure enhancements. These planned expansions include projects like the Delta Access initiative on its Transco pipeline system and the Shelby Trough Connector, an extension of its Louisiana Energy Gateway network. These investments signal Williams' intent to leverage the acquired assets and further solidify its position as a leading transporter of natural gas to global markets.

The transaction saw significant advisory involvement. BofA Securities served as the lead financial advisor to Williams, with Davis Polk & Wardwell providing legal counsel. Momentum Midstream received advisory services from Barclays and Jefferies, while Kirkland & Ellis acted as its legal counsel. EnCap Flatrock Midstream was advised by Willkie Farr & Gallagher.
