Antero Midstream Corporation filed its Form 10-K describing a fee-based midstream business that gathers, compresses and handles water for Antero Resources in the Appalachian Basin. The company operates extensive low- and high-pressure pipelines, compression facilities and water systems in West Virginia and Ohio.
The report highlights a $1.1 billion acquisition of HG Energy II Midstream Holdings’ gathering and water assets and a planned $400 million Utica Shale midstream divestiture, along with a prior $70 million Summit asset purchase. Antero Resources remains the key customer, holding a 29% ownership interest and dedicating most of its acreage under long-term contracts running to at least 2035–2038.
Management emphasizes a fixed-fee model with certain minimum volume commitments, just-in-time capital spending and a focus on maintaining a strong balance sheet and sustainable leverage. The filing also details extensive environmental, safety and regulatory obligations and reiterates significant customer-concentration and commodity-cycle risks tied to Antero Resources’ activity levels.
