Rice Midstream Partners LP (NYSE: RMP) owns, operates, develops, and acquires midstream assets in the Appalachian Basin, providing gathering and compression services; water services including fresh water distribution, produced water handling, recycling, and disposal; and related infrastructure such as pipelines, impoundments, and pumping stations servicing natural gas producers primarily in the dry gas cores of the Marcellus and Utica Shales in Pennsylvania and Ohio. The company operates through two primary segments: gathering and compression, which deliver natural gas from wells to transmission pipelines; and water services, supporting well completions and fluid management under long-term, fixed-fee contracts with key customers including affiliates of its former parent. Founded in 2014 and headquartered in Canonsburg, Pennsylvania, at 400 Woodcliff Drive, the partnership targets upstream producers in the Appalachian Basin with fee-based services focused on operational efficiency and regional contiguity.
In recent years, Rice Midstream Partners LP underwent significant restructuring, including its formation by Rice Energy Inc. (NYSE: RICE) as a master limited partnership for midstream growth, followed by Rice Energy's acquisition by EQT Corporation in 2017 for approximately $6.7 billion, which integrated contiguous acreage and retained certain midstream assets. In 2018, EQT Midstream Partners LP (EQM) acquired Rice Midstream Partners LP for about $2.4 billion in a merger transaction, exchanging RMP common and subordinated units for EQM units at a ratio of 0.3319 and assuming $325 million in debt, after which RMP was renamed RM Partners LP and became a subsidiary of Equitrans Midstream Corporation (formerly EQM post-restructuring). Additional 2015 developments included the $200 million acquisition of Rice Water Services entities from Rice Energy, expanding water infrastructure capacity to 15.9 million gallons per day with exclusive rights and options through 2025, alongside amended water services agreements extending to 2029. As of 2025, the entity continues as an active midstream operator under Equitrans Midstream, with its ticker RMP reflecting ongoing market presence amid consolidated Appalachian Basin operations.
