Williams Companies is in advanced negotiations to acquire Momentum Midstream in a deal valued at roughly $5.5 billion, a transaction that would significantly expand the natural gas pipeline operator’s already massive infrastructure network.
The talks, first reported by Bloomberg on June 28, 2026, and subsequently confirmed by Reuters, could result in a formal announcement within approximately one week. No final agreement has been reached, and the deal could still fall apart.
What Williams is buying and why it matters
Momentum Midstream operates natural gas gathering and processing assets across crucial US production basins. The company is backed by private equity firm EnCap Flatrock Midstream, which retains the option to keep the asset if negotiations don’t produce acceptable terms.
Williams already operates a pipeline network stretching around 30,000 miles across the US. Adding Momentum’s infrastructure would bolster that footprint at a time when demand for US natural gas, both domestically and for export, continues to climb.
