MPLX LP to Divest Rockies Gathering and Processing Assets

FINDLAY, Ohio, Aug. 27, 2025 /PRNewswire/ -- MPLX LP (NYSE: MPLX) today announced it has entered into a definitive agreement to divest its Rockies gathering and processing assets to a subsidiary of Harvest Midstream for $1.0 billion in cash consideration, subject to customary purchase price adjustments. Harvest has contractually agreed to dedicate approximately 12 thousand barrels per day of NGLs from these assets to MPLX for a period of seven years commencing in 2028, following the expiration of a pre-existing commitment.

"Evaluating the competitive positioning of our portfolio is a strategic commitment," said Maryann Mannen, MPLX president and chief executive officer. "The divestiture of these assets better positions our portfolio for growth, anchored in the Marcellus and Permian basins."

Assets included in the transaction are natural gas gathering and transportation pipelines and 1.2 billion cubic feet per day of processing capacity, which operated at 52% in 2024.

The transaction is expected to close in the fourth quarter of 2025, subject to customary closing conditions, including clearance under the Hart-Scott-Rodino Antitrust Improvements Act of 1976.
