Williams has agreed to acquire Houston-based Momentum Midstream for up to $5.5 billion. The transaction will expand Williams’ natural gas infrastructure across Texas and Louisiana.
The Williams Momentum Midstream acquisition will connect more Haynesville Shale production with Gulf Coast power plants, industrial facilities and liquefied natural gas terminals.
Tulsa-based Williams announced the agreement with its second-quarter financial results. The transaction remains subject to regulatory approval and customary closing conditions.
Deal Strengthens Haynesville Operations
Momentum operates a large network of natural gas gathering, treating, processing and transportation assets. Its infrastructure extends from East Texas through northern Louisiana.
The network includes approximately 4,000 miles of pipelines and serves more than 140 customers. Those customers include natural gas producers, utilities, industrial operations and LNG exporters.
Williams already has significant operations in the Haynesville region. Adding Momentum’s assets will give the company more capacity to move natural gas from production sites to major demand centers.
The Haynesville Shale has become an important supply region for Gulf Coast LNG exporters. Its location near terminals in Texas and Louisiana helps reduce the distance between production and export markets.
Williams has also invested in pipelines and other infrastructure serving power generation. Electricity demand from industrial growth and data centers has increased interest in reliable natural gas supplies.
Momentum Represents Company’s Sixth Iteration
Momentum was founded in Houston in 2004 by Bill Pritchard and Frank Tsuru. The company has developed or acquired thousands of miles of pipelines and several processing facilities.
Its current business is known as M6, representing the sixth major version of the company’s investment strategy. Each previous iteration built or acquired midstream systems before selling them to larger energy operators.
DCP Midstream acquired Momentum’s first collection of assets in 2007. Enterprise Products Partners bought the second portfolio in 2010 for $1.2 billion.
Later transactions involved DTE Energy and Williams. Williams acquired an operated interest in Momentum’s fourth iteration for $733 million in 2019.
That same year, DTE Midstream purchased assets from Momentum’s fifth iteration for $2.65 billion. Momentum later began developing M6 around natural gas infrastructure in East Texas and Louisiana.
The company expanded that platform through acquisitions and new construction. Its New Generation Gas Gathering project, known as NG3, entered service in 2025.
Houston Energy Market Records Another Major Transaction
The acquisition adds to a series of large transactions involving Houston energy companies. Private investment firm EnCap Flatrock Midstream supported Momentum’s growth with several other investors.
Momentum maintains its headquarters at 600 Travis Street in downtown Houston. The company’s local workforce helped develop its latest network across the Haynesville region.
Williams is headquartered in Tulsa but has a growing presence in Houston. It operates about 30,000 miles of pipelines and handles a significant portion of natural gas used across the United States.
The companies have not detailed how the acquisition may affect Momentum’s Houston employees. Integration plans could become clearer as the transaction moves through the approval process.
Acquisition Changes Williams’ Financial Outlook
Williams raised the midpoint of its 2026 adjusted earnings guidance after announcing the deal. The company now projects adjusted earnings before interest, taxes, depreciation and amortization at a midpoint of $8.4 billion.
Momentum’s long-term transportation and service agreements could provide Williams with predictable revenue. However, the company must complete the acquisition and integrate the network successfully.
The deal will also increase Williams’ exposure to natural gas demand from LNG terminals and power generators. Both markets are expected to require additional pipeline capacity along the Gulf Coast.
For Houston’s energy sector, the agreement demonstrates the continued value of locally developed midstream businesses. It also reinforces the region’s role in connecting domestic natural gas production with customers in the United States and abroad.
