Hess Midstream moved less oil and water, then made more money.
In the three months ended June 30, revenue fell to $399.0 million from $414.2 million a year earlier. Operating income also slipped, but net income rose to $96.4 million from $90.3 million, lifting net margin to 24.2% from 21.8%.
The business therefore split in two. The volume-sensitive top line contracted, while the costs beneath it fell faster. Operating margin edged up to 63.5% from 62.8%, and the company generated more cash with less capital spending intensity.
Management tied the revenue decline to lower production and new-well activity, not to a broad collapse in every operating line. The company's description is unusually concrete:
"Throughput volumes decreased 15% for oil terminaling and 12% for water gathering in the second quarter of 2026 compared with the second quarter of 2025, primarily due to lower production as a result of lower new-well activity."

That is the pressure point: fewer barrels and fewer water volumes moving through the system. Higher tariff rates and third-party services partly cushioned the decline, but they did not erase it.
The expense line did more of the work. Hess Midstream reported that operating costs and expenses fell to $145.8 million from $154.0 million, with lower employee and maintenance costs offsetting higher depreciation.
"Total operating costs and expenses in the second quarter of 2026 were $145.8 million, down from $154.0 million in the prior-year quarter, primarily due to lower employee costs and lower maintenance expense, partially offset by higher depreciation expense."
10-Q 2026-08-06; margin
The plain-English version is less dramatic than the earnings headline: Hess Midstream kept a little more of each dollar because it spent less to run the business. Net income improved even though operating income declined, and the latest filing does not spell out the full reason for that gap.
Cash generation also benefited from the capital cycle. Capital spending fell 52.3% year over year, while free-cash-flow margin improved by 14.3 percentage points. That reflects the completion of multi-year compression-capacity projects and the timing of payments for remaining property, plant, and equipment work, rather than a newly disclosed surge in demand.
The Chevron relationship gives the volume issue some shape. Hess Midstream says it generates substantially all of its revenue through fees under long-term commercial agreements with Chevron, with minimum volume commitments. The company also says that structure leaves it with minimal direct exposure to commodity prices. For this filing, that means the disclosed production and throughput changes matter more than the daily price of oil itself, at least at the fee-collection layer.
The balance sheet moved only slightly in the year-over-year comparison: cash rose to $5.0 million from $4.5 million, while accounts receivable increased to $142.9 million from $138.4 million. The next report's throughput volumes and operating-cost disclosure will clarify whether this was another period of lower activity paired with tighter spending, or a change in the volume trend.
Less throughput, more margin: Hess Midstream's three-month period was a scale trade-off.
