Background
US-based natural gas company Williams has agreed to purchase Momentum Midstream (M6 Midstream) from EnCap Flatrock Midstream in a deal worth up to $5.5bn. The transaction includes $3.5bn in cash and debt consideration and approximately $2bn in Williams equity.
Momentum Midstream, headquartered in Houston, Texas, operates more than 4,000 miles of natural gas-gathering and transmission pipelines. The network serves more than one million dedicated acres and supplies gas to critical Gulf Coast locations including the Bethel, Carthage and Silsbee hubs in east Texas and the Gillis hub in south-west Louisiana.
Its system has a capacity of around six billion cubic feet per day (bcf/d), serving more than 140 customers including industrial end-users, power plants, city gates and liquefied natural gas facilities.
Current situation
Completion of the acquisition is subject to regulatory review and standard closing conditions. Momentum Midstream's present owner, EnCap Flatrock Midstream, is a private equity firm founded in 2008 by Flatrock Energy Advisors and EnCap Investments.
In late 2022, Momentum Midstream acquired two gas-gathering and transmission assets in the Haynesville Shale. The company also made a final investment decision during that time on the New Generation Gas Gathering (NG3) project. The NG3 pipeline runs 255 miles, offering 1.75bcf/d of gas deliverability to Gillis, Louisiana. It also features a carbon capture and sequestration programme intended to handle up to 1.8 million tonnes of CO₂ annually.
In April 2025, Momentum Midstream closed its acquisition of Clearfork Midstream to transform into a wellhead-to-market natural gas midstream platform.
| Metric | Value | Change YoY |
|---|---|---|
| GAAP net income | $827m | +51% |
| GAAP diluted EPS | $0.68 | N/A |
| Adjusted net income | $614m | +8% |
| Adjusted diluted EPS | $0.50 | N/A |
| Adjusted EBITDA | $1.92bn | +6% |
Impacts
The acquisition is expected to expand Williams' natural gas infrastructure footprint along the Gulf Coast, adding significant pipeline capacity and customer access. Momentum Midstream's network serves more than 140 customers, including industrial end-users, power plants, city gates and LNG facilities, which could strengthen Williams' position in the region.
Williams raised its 2026 adjusted EBITDA guidance midpoint by $200m to $8.4bn, reflecting the inclusion of the Momentum acquisition. The company also reported unaudited financial results for the three and six months ended 30 June 2026, with GAAP net income of $827m, or $0.68 per diluted share, an increase of 51% compared with the same quarter in 2025.
Adjusted net income reached $614m, or $0.50 per diluted share, increasing year-on-year by 8%. Adjusted EBITDA was $1.92bn, a YoY rise of 6%. These figures indicate the company's financial health ahead of the deal.
Future outlook
Scenario analysis: The possibilities below are not certain predictions.
If the acquisition receives regulatory approval and meets closing conditions, Williams could integrate Momentum Midstream's assets, potentially boosting its Gulf Coast operations and customer base. The deal may also support growing demand for US hydrocarbons domestically and abroad, as noted by Momentum Midstream CEO Frank Tsuru.
However, if regulatory hurdles arise or market conditions change, the deal could be delayed or renegotiated. The final impact on Williams' financial performance will depend on integration success and future natural gas demand.
Williams also started building the Northeast Supply Enhancement project in April this year, which will expand its Transco pipeline network. This could complement the Momentum acquisition, but the combined effect remains to be seen.
