Is WMB a Buy? What to Consider in 2026
Short answer
The bull case for Williams Companies (WMB) rests on Fee-based gas transport core: The backbone of Williams is Transco, the highest-volume interstate gas pipeline in the U.S., supported by the Northwest Pipeline and extensive gathering and processing. Adjusted EPS (FY2025) is ~$2.10 per diluted share. If you believe that thesis holds, the real questions become position sizing and overlap, not timing. The main risk to that view: Williams carries meaningful leverage, with net debt of roughly $29.5 billion, so a period of higher-for-longer interest rates would raise refinancing costs and could compress free cash flow. Whether WMB is a buy comes down to whether you believe the thesis. This is informational, not a recommendation, and Walnut is not an investment adviser.
The Williams Companies, Inc. (NYSE: WMB) is a Tulsa-based energy infrastructure company focused almost entirely on natural gas. Its crown jewel is Transco, an interstate pipeline running more than 10,000 miles from south Texas and the Gulf Coast up the Atlantic Seaboard to the New York City area, complemented by the Northwest Pipeline in the Pacific Northwest and an extensive footprint of gathering, processing, and storage assets in basins such as the Marcellus and Haynesville. Williams makes most of its money through long-term, fee-based and capacity-reservation contracts under which customers pay to reserve and use pipeline space largely regardless of how much gas actually flows, which gives its cash flows a utility-like stability. Across its systems, Williams handles roughly a third of the natural gas used in the United States. Williams traces its roots to 1908 and has paid dividends for 52 consecutive years, making it one of the longer-tenured names in U.S. energy. The modern story is the convergence of two demand drivers: rising U.S. LNG exports that pull more gas toward Gulf Coast terminals, and a sharp increase in electricity demand from AI data centers that is reviving interest in gas-fired power generation. Williams has leaned into this with Transco expansions aimed at power-hungry regions like Virginia and a new power business that includes Project Socrates, a roughly $1.6 billion gas-fired generation buildout serving Meta in Ohio, part of about $7 billion of gas-generation projects targeted for completion by 2028. In FY2025 the company delivered record results, with adjusted EBITDA of about $7.75 billion (up 9%), adjusted earnings of roughly $2.10 per diluted share, and available funds from operations near $5.86 billion, and it raised its 2026 adjusted EBITDA guidance to a midpoint of about $8.2 billion.
What's the case for buying WMB?
1. Fee-based gas transport core.
The backbone of Williams is Transco, the highest-volume interstate gas pipeline in the U.S., supported by the Northwest Pipeline and extensive gathering and processing. The vast majority of EBITDA comes from long-term, fee-based and capacity-reservation contracts that insulate cash flows from short-term commodity prices. In FY2025 this model produced adjusted EBITDA of about $7.75 billion, up 9% year over year, and available funds from operations of roughly $5.86 billion. That stability is what underpins the long dividend record and management's mid-single-digit growth framing.
2. LNG export and Transco expansion growth.
Rising U.S. LNG exports increase demand for gas takeaway toward the Gulf Coast, and Williams is positioned across the Haynesville and other supply basins to serve it. The company continues to sanction Transco expansions, including projects aimed at power-hungry markets such as Virginia and a Power Express expansion upsized to roughly 750 million cubic feet per day. These contracted expansions add incremental fee-based EBITDA and helped lift 2026 adjusted EBITDA guidance to a midpoint near $8.2 billion. Expansions of existing pipeline corridors are typically cheaper and faster to permit than greenfield routes.
3. AI data-center power demand.
Surging electricity demand from AI data centers is reviving gas-fired power, and Williams has built a new power business to capture it. Project Socrates is a roughly $1.6 billion buildout of gas plants serving Meta in New Albany, Ohio, with a 10-year fixed-price agreement covering about 440 megawatts and start-up targeted for late 2026. It is one of four gas-generation projects totaling about $7 billion of capital expected online by the end of 2028, alongside behind-the-meter deals like the $2.3 billion Neo project (682 MW) and Atlas gas supply to a Northeast data center.
4. Durable dividend and balance-sheet capacity.
Williams has paid dividends for 52 consecutive years and raised the payout about 5% for 2026, to an annualized rate near $2.10 per share, a yield of roughly 3% at recent prices. Available funds from operations of about $5.86 billion in FY2025 comfortably covered the dividend, leaving room to self-fund a meaningful share of growth capital. As a C-corporation, Williams pays its distribution as an ordinary dividend reported on a 1099, which keeps tax filing simpler than an MLP's K-1 for most investors.
What are the risks to WMB?
Williams carries meaningful leverage, with net debt of roughly $29.5 billion, so a period of higher-for-longer interest rates would raise refinancing costs and could compress free cash flow. Although most revenue is fee-based, the company still has some exposure to natural gas volumes and a smaller slice of commodity-linked gathering and processing margins, meaning a sustained drop in drilling activity or gas prices in its key basins would weigh on results. Large interstate pipeline and power projects face permitting, legal, and regulatory risk, including FERC reviews and litigation that can delay or scale back expansions and the new gas-generation buildout. Project execution risk is real as Williams ramps spending on data-center power, and a faster-than-expected energy transition or policy shift away from gas infrastructure could impair the long-term value of its asset base.
How is WMB valued? (as of FY2025 results and latest quarter)
- Adjusted EBITDA (FY2025): ~$7.75 billion, up ~9% YoY
- Adjusted EPS (FY2025): ~$2.10 per diluted share
- Available funds from operations (FY2025): ~$5.86 billion
- 2026 Adjusted EBITDA guidance (midpoint): ~$8.2 billion
- Dividend yield (approx.): ~3%, annualized rate near $2.10/share
- Net debt (approx.): ~$29.5 billion
- Market cap (approx.): ~$75 billion
Reading a midstream C-corp like Williams is less about GAAP net income and more about contracted cash flow. Investors typically focus on adjusted EBITDA, available funds from operations (AFFO) or distributable cash flow, dividend coverage (AFFO comfortably exceeded the dividend in FY2025), and leverage measured as net debt to EBITDA. Because most EBITDA is fee-based, results are steadier than a producer's, and the headline EV/EBITDA multiple captures the market's view of that durability plus growth from expansions and power projects. As a C-corporation, Williams reports its payout on a 1099 dividend form rather than the K-1 that MLP-structured peers issue, which simplifies tax filing.
How do you decide if WMB is a buy?
Rather than asking whether WMB is a buy in the abstract, it tends to help to answer four questions:
- Thesis: do you believe the case above, and is it still true today?
- Time horizon: a single stock can be volatile, so a longer horizon absorbs more of the swings.
- Position sizing: a thesis can be right and the sizing still wrong; decide how much of your portfolio one name should be.
- Overlap: check whether you already hold WMB indirectly through an index or sector ETF before adding more.

The bottom line on WMB
The bottom line: Williams Companies's story right now is Fee-based gas transport core, with adjusted eps (fy2025) at ~$2.10 per diluted share. If you believe that narrative continues, the call is about sizing WMB sensibly and checking overlap with what you own; if you doubt it (the risk: williams carries meaningful leverage, with net debt of roughly $29.5 billion, so a period of higher-for-longer interest rates would raise refinancing costs and could compress free cash flow.), it is not for you.
