Williams put $2.7 billion into capital projects in the third quarter, excluding acquisitions, against $1.5 billion of cash from operations: about 1.8 times what its business generated, by our arithmetic from its release. A year earlier it invested $1.05 billion, less than the $1.44 billion of operating cash it brought in.
The gap was covered from outside. In July an investor put $3.74 billion into Pantheon, the Williams subsidiary that owns its five power projects, part of $5.34 billion of committed capital that the 10-Q says is “dedicated for funding the construction of the power projects”.
An evergreen Business Engineer explainer on free cash flow: what is left after a company pays for its investments. It explains the general idea only and does not discuss Williams’ results.
The key insight: As we read the release, Williams is now investing well beyond what its pipelines throw off in cash, about 1.8 times in the third quarter by our arithmetic, while an outside investor’s committed capital funds construction of the power projects.
Capital expenditures reached $2.489 billion in the quarter, 2.6 times the $954 million of a year earlier, by our arithmetic. The Transmission, Power & Gulf segment, which holds the interstate pipelines and the power projects, accounted for $1.864 billion of it, or 75%.
That segment’s spending was 2.8 times its level a year earlier. The release’s quarterly schedule shows it rising from $369 million in the first quarter of 2025 to $1.864 billion in the third quarter of 2026.
On top of the capital programme, Williams paid $2.816 billion in the quarter for Momentum Midstream, which the release says strengthens its Haynesville position. The 10-Q puts its total consideration at about $5.1 billion.

Wall St Engine (@wallstengine) posted its Williams Q3’26 highlights card at 21:08 UTC on 2 November: revenue of $3.22B, adjusted EPS of $0.54 against a $0.55 estimate, adjusted EBITDA of $2.04B, affirmed 2026 guidance including growth capex of $7.3B-$7.9B, cash flow from operations of $1.51B, and the Momentum Midstream acquisition closed ahead of schedule. The piece checks each figure against Williams’ own release and 10-Q.
The Power Projects
The 10-Q lists five power projects. Socrates, in New Albany, Ohio, has an expected 556 MW; its southern half entered service in late July and its northern half is expected later in the fourth quarter, according to the filing. It runs under a 10-year, primarily fixed-price power purchase agreement.
Four more are contracted: Apollo in Ohio, 490 MW; Aquila in Utah, 520 MW; Socrates the Younger in Ohio, 340 MW; and Neo in Ohio, 682 MW, with expected in-service dates in 2027 and 2028, the 10-Q says. Together the five come to 2,588 MW, about 2.6 GW, by our arithmetic.
Socrates South already shows up in results. The 10-Q attributes a $53 million rise in power revenues in the segment mainly to it. Williams accounts for the Socrates South agreement as an operating lease, with income recognised in service revenues.
Chief executive Chad Zamarin said in the release that Socrates is “the first of many power projects” and that Williams is “actively working to commercialize additional power projects, which we expect to announce soon”.
The Financing
Williams kept 51% of Pantheon and control of it. It sold the other 49% for $5.34 billion of committed capital: $3.74 billion arrived in July and $1 billion more in October, the 10-Q says. Williams has a buyout right in years 7 to 14 at a price giving the investor “a specified return”.
The rest came from debt markets. Over nine months Williams raised $5.538 billion of long-term debt and repaid $1.137 billion. Debt-to-adjusted EBITDA was 3.80 times at quarter end, the release says, against 3.73 times a year earlier.
The Quarter in Numbers
Adjusted EBITDA rose 6% to $2.039 billion, and adjusted earnings per share were $0.54, against $0.49. Available funds from operations covered the dividend 2.42 times. Total revenues were $3.223 billion.
The release says Williams is tracking toward the upper half of its $8.3 billion to $8.5 billion adjusted EBITDA guidance for 2026. With $6.214 billion in the first nine months, the upper half implies $2.186 billion to $2.286 billion in the fourth quarter, by our arithmetic.
Wall St Engine’s card on X lists estimates of $2.02 billion for adjusted EBITDA and $0.55 for adjusted earnings per share; Williams reported figures above the first and below the second.
What the risk factors say
Williams’ 10-Q points to the risk factors in its 2025 annual report and says “Those Risk Factors have not materially changed”.
As we read it, the step-up is concentrated: the Transmission, Power & Gulf segment took 75% of third-quarter capital expenditures, by our arithmetic, up from about a third in the first quarter of 2025.
As we read the 10-Q, the Pantheon structure lets Williams keep control of the power projects while an outside investor funds construction, with a buyout right in years 7 to 14 at a specified return.
As we read the filings, the power projects are contracted before they are built: each of the five has a power purchase agreement, mostly fixed-price, with terms of 10 to 12.5 years.
Chad Zamarin, president and chief executive, Williams, in the Q3 2026 earnings release
“As the first of many power projects, Socrates demonstrates our ability to deliver fast, reliable and scalable solutions for customers facing rapidly growing power demand”
Three Implications
FOR WILLIAMS’ CASH FLOW Capital investments of $2.727 billion against $1.505 billion of operating cash flow in the quarter left a gap of about $1.2 billion, by our arithmetic, before the Momentum acquisition.
FOR POWER BUYERS The 10-Q lists 2,588 MW across five contracted projects, by our arithmetic, with expected in-service dates running to the second half of 2028.
FOR LEVERAGE The release puts debt-to-adjusted EBITDA at 3.80 times at quarter end, against 3.73 times a year earlier, after $5.538 billion of new long-term debt in nine months.
The framework sets out the dependency this way: “You cannot ship foundries without energy. The bedrock dictates what the upper floors can do.”
As we read it, a pipeline company building contracted power plants is spending at that bedrock layer. The framework does not discuss Williams, and the filings do not say who buys the power.
What Is Not Established
The filings do not name the customer for the power projects, the Pantheon investor or the specified return. They do not say what the power will be used for; we make no claim about data centres.
Capital investments in the release include equity-method contributions as well as plant spending, so the 1.8 times ratio compares a broader measure of investment with operating cash flow. We did not use Williams’ earnings call.
This Week In The AI Supercycle
Anthropic’s Reality Check, The Capital Squeeze, & The New World Order
This week’s issue: for two years the AI build-out was priced as a growthstory. This week it started being priced as a credit story.
Williams invested about 1.8 times its third-quarter operating cash flow, by our arithmetic, with three-quarters of its capital spending in the segment that holds its pipelines and power projects. A partner’s $5.34 billion of committed capital funds the five power projects, which add up to about 2.6 GW.
