What happened

A group of natural-gas pipeline and gathering companies that move fuel to power plants and data centers has spent the past year quietly compounding, even as the nuclear and power-generation stocks pitched as the more exciting way to bet on AI electricity demand have broken down. The five core names — Williams, Energy Transfer, Kinder Morgan, DT Midstream and TC Energy — are all up double digits over 12 months and all still sit in bullish price trends with zero bear-signal days since May. Over the same stretch, Constellation Energy, Vistra and Talen — nuclear-heavy power producers — are down 12%-29%, and uranium supplier Cameco and reactor-component maker BWX Technologies have rolled over sharply in just the past month. The difference isn't sentiment on both sides; the pipeline group's gains trace to specific, signed contracts, while the power names' declines are attributed by analysts to broad AI-capex anxiety with no company-specific bad news.

The pipeline names, and what backs the move

Williams, which owns Transco, the largest natural-gas pipeline in the country, is extending that network with a roughly $16 billion, 14-billion-cubic-feet-per-day expansion backlog and a reported $5.5 billion purchase of Momentum Midstream's gathering systems, which already serve 10 LNG export facilities and 26 power plants; the company is also deploying $7 billion into projects that supply power directly to large customers, including an initiative called Socrates, per Yahoo Finance. Kinder Morgan, which transports roughly 40% of all natural gas used in the U.S., ended its latest quarter with a $9.6 billion project backlog, of which more than 60% is tied directly to power-generation and data-center demand, and it raised full-year earnings guidance as those projects moved toward completion, according to Pipeline & Gas Journal. DT Midstream, a gathering and pipeline operator concentrated in the Haynesville and Appalachian shale regions, sanctioned a new expansion of its LEAP pipeline system that is "fully underpinned by long-term take-or-pay commitments" with two producers, and separately built a new interconnect to supply a gas-fired power plant serving a data center in Ohio, per Natural Gas Intelligence and Yahoo Finance. Energy Transfer, a pipeline and export-terminal operator, has roughly 900 million cubic feet a day of gas-supply contracts tied to Oracle data centers, and its adjusted earnings grew nearly 20% year over year as a newly sold-out pipeline project, Hugh Brinson, heads toward service late this year. TC Energy, a Canadian pipeline operator that also holds a stake in the Bruce Power nuclear plant, is positioned by industry analysts as a leading beneficiary of a widening U.S. gas supply gap. Targa Resources, a gas gatherer and processor concentrated in the Permian Basin that corroborates the trend rather than anchoring it, has held an uninterrupted bullish price trend for 155 consecutive trading sessions since mid-December — a shorter run than the 232 sessions sometimes cited, but still the longest streak in the group.

Fundamentals: CONFIRMS

The price action tracks the business. Kinder Morgan's adjusted earnings before interest, taxes, depreciation and amortization (EBITDA) rose 12% year over year last quarter; Energy Transfer's rose 19.5%; Williams' rose 9%. Leverage at Energy Transfer sits within its 4.0x-4.5x target range, and Kinder Morgan's net debt is 3.6x EBITDA against a 3.7x target, with growth spending funded mainly from retained cash flow rather than new equity. On price-to-gross-profit, a valuation lens that works across differing leverage and payout structures, the pipeline group trades at 4x to 15.5x — with DT Midstream, at roughly 15.5x and a 32x trailing price-to-earnings ratio, the one name trading rich to its peers — versus 9x to 40x for the nuclear and uranium names, meaning midstream's rerating has not caught up to what investors still pay for nuclear exposure even after that group's steep pullback.

The nuclear side: a sentiment break, not a contract loss

Constellation, Vistra and Talen sold off together on July 27 with "no fresh company catalyst," a decline that coverage tied to sector-wide worry that AI data-center capital spending is running ahead of demand, per QuiverQuant. Constellation is down roughly 20% this year despite a 20-year, 2,600-plus-megawatt supply agreement with Meta signed in January. Cameco, a uranium miner, has fallen 18% in the past month even as coverage attributes the move to "broader market and AI-related sentiment rather than any change in the company's fundamentals," per nai500. That is the core contrast: nuclear and uranium names carry higher valuations and support built more on expectation than signed volume, while the pipeline group's gains are backed by disclosed, in-service contracts.

One alternative explanation for the pipeline rally — that it's simply a bond-proxy trade benefiting from falling interest rates — does not hold up. The 10-year Treasury yield rose from about 4.2% in February to roughly 4.75% by July, a headwind for high-yield sectors, yet the pipeline group compounded through it, per heygotrade; commentary on the sector argues this dynamic hurts nuclear and utility yield plays more than gas transport, whose returns were driven by EBITDA and contract growth rather than yield compression, per Yahoo Finance. Underlying gas fundamentals also support the setup: the U.S. Energy Information Administration expects Henry Hub gas prices to rise from about $3.5-$3.8 per million British thermal units in 2026 toward roughly $4.60 in 2027 as liquefied natural gas exports ramp 11%, tightening the domestic gas balance, per EIA.

Technicals

All five core names have held mild-to-strong bullish price trends with zero bear-signal days since May, and the group's trailing 30-day return is essentially flat (about +0.4% average), meaning the past month's move is consolidation, not a fresh breakout — consistent with a name group compounding on contract news rather than chasing a chart signal.

The setup

Where it stands — The five-name gas-pipeline group holds bullish price trends and contract-backed earnings growth while the nuclear/IPP group sits mostly in bearish trends on sentiment. Would confirm — Kinder Morgan's project backlog (currently $9.6B) growing further with disclosed take-or-pay counterparties rather than shrinking through cancellations. Would invalidate — Any of the five pipeline names posting EBITDA growth below prior-year guidance or leverage breaching its stated target range. Watch next — DT Midstream's LEAP Phase 5 in-service date, targeted for the second half of 2028, and continued quarterly backlog disclosures through year-end 2026. Valuation — Group trades 4x-15.5x price-to-gross-profit (DTM richest at 15.5x, ET cheapest at 4.1x) versus 9x-40x for the nuclear/uranium comparison group.
