Antero Midstream owns and operates energy infrastructure that primarily serves Antero Resources’ natural gas production and well-completion activity in the Appalachian Basin. Its chief executive officer and president is Michael N. Kennedy.
The company gathers natural gas and natural gas liquids from wells through pipelines and uses compressor stations to move them through its system. It also owns interests in plants that process natural gas and separate natural gas liquids into products. These operations form its gathering and processing segment.
Its water handling segment delivers water used to complete wells and provides other fluid services associated with production. The water systems include pipelines, pumping stations, storage facilities and blending facilities. Portions of the systems also transport water that returns from wells during completion and production.
Antero Midstream provides services itself and through contracted third parties. Its assets are located in West Virginia and Ohio, and substantially all of its revenue currently comes from Antero Resources. Antero Resources also owned 29% of Antero Midstream as of December 31, 2025.
Antero Midstream acquired gathering and water assets in West Virginia in February 2026. It also agreed to sell substantially all of its Utica Shale midstream assets in Ohio, a transaction it expected to close in February 2026.
How it makes money
Antero Midstream earns fees for gathering and compressing gas, processing and fractionation services, and water handling. It also records earnings from interests in businesses that provide processing, fractionation and high-pressure gas gathering services.
For the year ended December 31, 2025, total revenue was $1.2 billion.
Gathering and processing segment revenue was $950.2 million in FY2025, while water handling segment revenue was $238.2 million. The gathering and processing segment includes pipelines and compressors serving Antero Resources’ wells as well as investments in the Joint Venture and Stonewall. The water segment delivers fresh water and provides services such as wastewater transportation, disposal and blending.
Under its gathering and compression agreements, Antero Midstream receives fees for low-pressure gathering, high-pressure gathering and compression, as applicable. Those fees are charged per unit of gas and adjusted annually based on the consumer price index. Some agreements include minimum volume commitments or minimum fees. For certain new construction requested by Antero Resources, Antero Midstream can elect either minimum volume commitments or a cost-of-service fee for each item of equipment placed in service.
Fresh water delivered by pipeline to a well site earns a fixed fee, also subject to annual inflation adjustments. The water services agreement has no minimum volume commitments. For other fluid services provided by third parties, Antero Resources reimburses the third-party costs plus 3%; for services Antero Midstream provides itself, it charges a cost-of-service fee.
The company provides services under long-term agreements: gathering and compression agreements run through 2038 and the water services agreement runs through 2035. Fixed fees limit direct exposure to commodity prices, although Antero Resources’ drilling plans affect demand for the services.

Customers and how it sells
Antero Resources is Antero Midstream’s most significant customer, and Antero Midstream currently derives substantially all of its revenue from it. The services support Antero Resources’ gas production, well completions and handling of fluids from producing wells. Antero Resources owned 29% of Antero Midstream as of December 31, 2025.
The company’s operating systems are concentrated in the Appalachian Basin, principally in West Virginia and Ohio. Its gathering and processing assets collect production from Antero Resources’ wells, while its water systems draw from sources including the Ohio River, local reservoirs and regional waterways. Antero Midstream delivers services directly or through contracted third parties.
As of December 31, 2025, substantially all of Antero Resources’ approximate 566,000 gross acres were dedicated to Antero Midstream for gathering, compression and water services. The gathering and compression agreements also dedicate substantially all of Antero Resources’ current and future acreage in West Virginia, Ohio and Pennsylvania to Antero Midstream for those services.
Antero Resources can dispose of dedicated properties free of those dedications under certain circumstances. Antero Midstream also seeks third-party volumes for its gathering, compression and water systems.
| Segment | Revenue, FY2025 | Share | Change on the year |
|---|---|---|---|
| Gathering and Processing | $950.2 million | 80.0% | 6.89% |
| Water Handling | $238.2 million | 20.0% | 9.67% |
Suppliers and costs
Antero Midstream operates pipelines, compressors and water infrastructure rather than manufacturing products. Its water systems draw from the Ohio River, local reservoirs and regional waterways. For some fluid handling services, the company contracts with third parties; Antero Resources reimburses those out-of-pocket costs plus 3%.
Antero Resources also seconds employees to Antero Midstream for operational and corporate services. Antero Midstream reimburses direct expenses and an allocation of indirect expenses for those services under agreements extending through 2039.
Direct operating expenses were $232 million for the year ended December 31, 2025, up from $218 million in 2024. Higher gathering and compression volumes, maintenance and costs associated with acquired assets contributed to the increase. Water handling expenses rose with higher fluid volumes, wastewater trucking and disposal costs, and blending costs.
Antero Midstream expects increasing regulatory compliance costs. Inflation and supply-chain disruptions can also increase operating and capital costs that are not fixed, although gathering, compression and water agreements include annual inflation-based fee adjustments.

Competitive position
Antero Midstream does not compete for Antero Resources’ existing operations for which it already provides midstream services, or for future operations dedicated to it under the relevant gathering, compression, water and processing agreements. It does face competition for third-party volumes on its gathering, compression and water systems. Potential third-party customers may also develop their own systems rather than use Antero Midstream’s assets.
No competing company is identified by name in the available business descriptions. Antero Midstream has a processing and fractionation joint venture with MarkWest; the relationship is a partnership, not an identified competitive matchup.
Our reading: The acreage dedications and long contract terms provide a meaningful contractual barrier around work for Antero Resources, but that protection depends on the customer and the terms of the agreements. Antero Resources can dispose of certain dedicated acreage free of the dedication, and the water agreement has no minimum volume commitments.
Our reading: Antero Midstream’s connected pipelines, compression facilities and water systems support its position with its existing customer because they serve wells and completion activity in the same operating area. That infrastructure does not eliminate competition for other producers’ volumes, including competition from systems those producers could build themselves.
Growth opportunities
Antero Midstream’s activity is tied to Antero Resources’ drilling and completion program. Antero Resources announced a 2026 drilling and completion budget of $1.0 billion to $1.2 billion, including plans to complete 70 to 80 net horizontal wells in the Appalachian Basin. Its budget reflects the closing of its HG production acquisition and assumes a February 2026 closing of its Utica asset divestiture.
Antero Midstream closed its $1.1 billion acquisition of HG Midstream on February 3, 2026. The assets include gathering pipelines and integrated water handling facilities in West Virginia’s Marcellus Shale. The company intends to modify its arrangements with Antero Resources to provide on-pad compression for certain wells and a transition period through 2026 before certain water services are provided under existing agreements.
The company also agreed to sell substantially all of its Utica Shale midstream assets in Ohio for $400 million, with closing expected in February 2026 subject to conditions. It expects to use the net proceeds to repay long-term debt.
Antero Midstream announced a 2026 capital budget of $190 million to $220 million. The budget reflects the HG acquisition and assumes the Utica divestiture closes. The company adjusts capital spending in response to Antero Resources’ development plans and other business conditions, and it looks for opportunities to reuse or repurpose existing assets.

Structural risks
- Customer concentration: Substantially all revenue currently comes from Antero Resources. A slowdown in its development program, production shut-ins, financing difficulties or other adverse developments could affect demand for Antero Midstream’s services.
- Commodity and volume exposure: Fixed fees limit direct exposure to commodity prices, but changes in gas, natural gas liquids and oil prices can affect Antero Resources’ cash flows and development plans. The water services agreement has no minimum volume commitments.
- Operating hazards and geography: The systems are concentrated in the Appalachian Basin. Leaks, fires, explosions, pipeline damage, impoundment breaches or other incidents could interrupt operations and lead to remediation costs, claims or penalties.
- Regulation: Changes in pipeline classification, safety rules or environmental requirements could increase operating or capital costs. Antero Midstream expects regulatory compliance costs to rise.
- Debt and transactions: Cash flow may be insufficient to service debt, and financing agreements restrict some activities. The company may not achieve the intended benefits of the HG acquisition, and the acquisition may disrupt existing plans or operations.
Bottom line
Our reading
Our reading: Antero Midstream is a fee-based infrastructure business built around a close operating relationship with one producer in Appalachia. Its contracts and connected assets support that relationship, while its dependence on Antero Resources leaves volumes exposed to the customer’s drilling decisions and financial condition. The HG acquisition expands its asset base, but debt obligations and the planned Utica sale also matter to how the company funds its operations.
