Williams Companies (WMB) Met Q2 Estimates, Is It Still Below Fair Value?

Listen to the news

Williams Companies (WMB) recently reported Q2 FY26 results that matched earnings expectations, putting fresh attention on how this large US natural gas infrastructure operator earns its money and manages its pipeline network.

Recent trading has been choppy for Williams Companies. The share price is up 1.23% over one day and 4.51% over the past week, yet down 4.60% over 30 days and 3.57% over 90 days. At the same time, the year-to-date share price return of 18.88% and 1-year total shareholder return of 18.13% indicate momentum that has cooled in the short term but remains solid over a longer window.

Scan the midstream space by comparing Williams Companies with a hand-picked 43 power grid technology and infrastructure stocks that could benefit from the same demand for reliable energy infrastructure.

That combination of a cooled near-term chart and strong multi-year gains raises a practical question for Williams Companies investors: Is most of the rerating already in the rearview mirror, or does the current valuation still leave room ahead?

Most Popular Narrative: 15% Undervalued

Williams Companies last closed at $72.34, compared with a widely followed fair value estimate of $85.61 that applies a 7.24% discount rate. That gap rests on a story built around Haynesville gas, Gulf Coast LNG routes, and a growing power platform sitting on long-term contracts.

The Power Innovation platform, backed by a US$5.34b equity funding commitment from partners, is supporting a series of behind the meter projects such as Socrates and Neo that carry multi year contracts, which can add incremental contracted earnings and improve overall returns on invested capital.

The commercialization of Neo, a 682 MW behind the meter power project with a 12.5 year contract and an expected build multiple of about 5x, together with continued phases of Socrates, provides Williams Companies with a growing base of long duration power cash flows that can support EBITDA growth beyond the traditional pipeline business.

See why 28 investors see Williams Companies as 15% undervalued.

Result: Fair Value of $85.61 (UNDERVALUED)

Still, the Williams Companies story can be knocked off course if permitting setbacks slow key pipelines, or if higher leverage around 4.1x constrains future funding.
