Williams Closes $5.5B Momentum Deal, Lifts EBITDA Guide

Williams Companies (NYSE: WMB) closed its
$5.5 billion acquisition of Momentum Midstream on Sept. 3, 2026, just
one month after the deal was announced on Aug. 3. The Tulsa-based pipeline operator now folds Momentum’s Haynesville
gas-gathering and processing footprint into a network that spans roughly 32,000 miles of pipeline. Alongside the close,
Williams raised its 2026 adjusted EBITDA guidance to a range of
$8.3–$8.5 billion, a signal management already sees the assets contributing this year.

The deal at a glance

Momentum Midstream operated in the Haynesville shale of East Texas and North Louisiana, a basin whose relevance has
been re-underwritten in the last two years by two very specific demand drivers Williams cited in its
acquisition press release: Gulf Coast liquefied natural gas (LNG)
export terminals and, more recently, gas-fired power to feed AI data centers along the I-10 corridor. Gathering and
processing volumes in the Haynesville feed directly into that demand.

Why one month is fast for a $5B midstream deal

Sign-to-close in about 30 days is quick for U.S. midstream M&A. Antitrust review by the Federal Trade Commission
typically runs a 30-day Hart-Scott-Rodino
waiting period for cash deals of this size before the parties can close — often extended if the FTC issues a
second request. The compressed timeline suggests early termination or, at minimum, a clean review, which itself is a
data point on how regulators are viewing gathering-and-processing consolidation. Buyer and seller also had to complete
Federal Energy Regulatory Commission and state-level utility approvals where the assets touch interstate systems.

A midstream operator now leaning harder on Gulf Coast demand

Williams framed the acquisition around two structural shifts. The first is the multi-year build-out of Gulf Coast
LNG. The U.S. Energy Information Administration projects U.S. LNG
export capacity to keep expanding through 2028 as new terminals ramp; those terminals need feedgas, and the Haynesville
sits closer to Louisiana and Texas coastal export points than any other major dry-gas basin. The second is
gas-generation demand from data centers and grid additions in Texas and along the Gulf Coast, a theme the
EIA electric power monthly has been tracking as commercial power
load runs above prior forecasts.

Fits with the Blackstone Power Innovation JV

The Momentum close comes two months after Williams and Blackstone announced a
$5.34 billion Power Innovation joint venture in July, a vehicle
targeting dispatchable power infrastructure for large industrial and data-center loads. Read together, the two moves
outline a strategy: buy gathering and processing where the molecules are cheapest (Haynesville), and pair that supply
with generation platforms that monetize the demand side. That’s a different playbook than the “grow the fee-based
book” version of midstream that dominated the last cycle.

Balance-sheet questions the market is watching

Williams did not publicly detail the financing mix at close. The company entered 2026 with an investment-grade
credit profile and a large capital-expenditure book already committed to organic projects such as the Southeast Supply
Enhancement and Northeast Supply Enhancement lines highlighted on the company’s
project page. Between the JV commitment with Blackstone and the Momentum close, near-term free-cash-flow
conversion, leverage evolution, and any incremental debt issuance are the next questions for fixed-income and equity
investors alike. WMB traded around $74.05, down about 1.5% on the close-day session per Yahoo Finance.

What to watch next

• Q3 2026 earnings. First quarter that includes Momentum contribution; management will need to
  reconcile the raised 2026 EBITDA range with a full quarter of asset performance.
• Financing disclosures. Any follow-on senior notes or term-loan announcements will clarify how
  much of the $5.5 billion was funded with cash and revolver versus new debt.
• Haynesville rig count. The Baker Hughes rig
  count for the Haynesville is the single fastest read on how much gas Momentum’s system will process.
• Gulf Coast LNG start-ups. New export capacity coming online in 2026–2027 is what pulls
  incremental molecules through Williams’ pipes.
