- Equitrans Midstream Corporation, a wholly owned subsidiary of EQT Corporation following its completion of an all-stock acquisition by EQT in July 2024 valued at over $35 billion including debt, provides midstream services focused on natural gas gathering, transmission, storage, and water infrastructure in the Appalachian Basin across Pennsylvania, West Virginia, and Ohio; its core assets include high-pressure dry gas gathering systems, FERC-regulated interstate pipelines such as the Mountain Valley Pipeline in which it holds a 48% interest and which nears 94% completion, underground storage systems, and an extensive water network featuring permanent and temporary water pipelines, 350,000 barrels of above-ground storage capacity at two facilities, water sourcing, full program management, SCADA measurement solutions, and produced water handling for unconventional development. Headquartered in Canonsburg, Pennsylvania, and founded in 2018 as a spin-off from EQT to house its midstream operations, the company previously acquired EQM Midstream Partners in a $2.2 billion share-for-share merger in June 2020, consolidating ownership of key gathering, transmission, and storage assets originating from Marcellus and Utica shale regions; it serves natural gas producers and industrial customers under long-term contracts with dedicated engineering, construction, operations, and permitting teams emphasizing performance, safety, and recycling. The 2024 merger with EQT integrates Equitrans' assets into a vertically integrated natural gas entity, unlocking over $425 million in projected annual synergies, enhancing drilling economics for approximately 4,000 locations, and suspending its independent SEC reporting obligations while transitioning stakeholder inquiries to EQT platforms.
