Targa Resources told investors on 17 August that subsidiaries of ExxonMobil had dedicated acreage in the Delaware and Midland basins to it under fee-based agreements running through 2046. The deal is integrated: Targa gathers the gas at the wellhead, processes it, and takes the resulting natural gas liquids (NGLs) downstream. It comes with three new Permian Delaware processing plants adding roughly 825 million cubic feet a day by 2028 and a 70-mile pipeline, Bull Run II, lifting takeaway to the Waha hub. Full-year net growth spending was raised to about $5.0bn in the same breath.

Targa — a Houston group with roughly 28,400 miles of gathering pipe, 42 processing plants and a Gulf Coast liquids export business — is the dominant processor in the Permian, with about a quarter of regional capacity. Its shares rose 8.4% the session after the announcement, on 2.49m shares against 0.43m the day before. That single day more than accounts for the entire month's gain across the seven largest gathering-and-processing companies.

The advance is earnings, not re-rating

Revenue is a poor read on this business, because most of it is commodity pass-through; in the first quarter, revenue fell 15.6% while gross profit rose 37.9%. Gross profit is the honest line, and in the second quarter it reached $2.14bn, up 139% from a year earlier, on a gross margin of 48.2% against 22.2%. Adjusted earnings before interest, taxes, depreciation and amortization (EBITDA) set a record at $1.603bn, up 38%. Permian plant inlet volumes hit a record 7.2 billion cubic feet a day.

So the price paid per dollar of trailing gross profit is about 10.6 times today — against roughly 11.9 times three months ago and 10.9 times in February. The stock is up 30.9% over six months and is no dearer per dollar of gross profit than when it started. On forward estimates the figure falls to about 9.2 times. Trailing price-to-earnings is 28.4, forward 26.6, priced off consensus for a 32% earnings step-up in 2026 that decelerates to 9.5% in 2027.

Two things temper it. Management said roughly $250m of first-half marketing and optimization margin was not in guidance and should not be assumed to repeat. And the growth is bought, not free: about $5.0bn of net growth capital against $5.7–5.9bn of guided EBITDA, leverage at 3.4 times, a trailing free-cash-flow yield of 1.15%, and a second-quarter buyback of $80m — 308,102 shares, about 0.14% of the count. Management points to a cash-flow inflection only after its export expansion completes in late 2027.

The constraint is takeaway, not load

The mechanism in the Permian this year has been oversupply, not demand pull. Waha hub prices were negative for 118 of the first 131 days of 2026, averaging -$2.19 per million British thermal units, with a record -$7.95 in late April. That forced Targa to accept 200–400 million cubic feet a day of producer shut-ins in the second quarter, resolved by July. The emerging squeeze is geographic: about 5 billion cubic feet a day of new processing capacity is being built in the northern Delaware while nearly all long-haul lines start at Waha. Bull Run II is aimed precisely at that gap.

None of that is artificial intelligence. Targa's gas marketing team is in discussions to supply fuel to behind-the-meter power projects, but no volume is contracted. The only one of these companies with a firm power deal is ONEOK, the Tulsa system that spans gathering, NGLs and refined products: a 1-gigawatt gas supply agreement requiring over $100m of capital, with more than 40 counterparties in discussion. ONEOK's shares are up 1.8% over three months. It trades at 16.1 times trailing earnings against 16.2 times forward — no growth priced — and 6.8 times gross profit, the cheapest of the three.

Antero Midstream: volumes up, earnings flat

Antero Midstream gathers and compresses gas in West Virginia and Ohio almost entirely from one affiliated producer, Antero Resources, and handles its water. Second-quarter gathering volumes rose 20% year over year to 4.1 billion cubic feet a day. Adjusted EBITDA rose 2%. Gross profit fell 1.7%, with margin down from 64.7% to 58.7%, and net income fell 8.8%. The volume came from the acquired HG Midstream assets, not from new demand.

It is nonetheless the more expensive stock: 12.7 times trailing gross profit and 12.5 times forward, against Targa's 10.6 and 9.2. The balance sheet is the strong part — leverage of 2.8 times after a $370m litigation settlement received in July, a twelfth straight quarter of free cash flow after dividends, a 9.3% trailing free-cash-flow yield. Its first regional pipeline, Eastside Express, is framed as a bet on West Virginia power and data-center demand at $200–300m of capital — underwritten by an affiliate acreage dedication with no minimum volume commitments.

What the trend does and does not say

Targa's 50-day average has sat above its 200-day continuously since 12 December 2025, the longest such run among these seven; Antero Midstream's ended on 18 August, on a day its shares actually rose 1.91%, after seven weeks stuck below its 26 June high of $23.19. Nor was the group's big session a bond-market bid: the 30-year Treasury yield topped 5.33% that same day, a 19-year high. Twelve-month returns inside the group run from Targa's +86.9% to Hess Midstream's -5.5%, with Kinetik, Western Midstream and MPLX in between. Targa is leading on results; Antero Midstream is diverging, growing throughput without growing earnings; ONEOK is following the group while holding the only contract that matches the story being told about all of them.

The setup

Where it stands — Targa's advance is funded by record Permian volumes and a 20-year Exxon dedication, not by any contracted power demand. Would confirm — Third-quarter adjusted EBITDA at or above $1.5bn with the $25–50m of returning shut-in margin recognized. Would invalidate — Fourth-quarter gross profit falling back toward $1.2bn as the $250m marketing windfall lapses without volume offset. Watch next — Third-quarter results in early November, and the East Driver and Train 11 utilization disclosure. Valuation — 10.6x trailing gross profit, 9.2x forward, against 11.9x three months ago and ONEOK's 6.8x.
