Marathon Petroleum and its midstream affiliate MPLX are reshaping their refining footprint through an agreement to sell two refineries and related assets to CVR Energy. Tank Storage Magazine reported on Friday, November 13, 2026 that the transaction covers the St. Paul Park refinery in Minnesota, the Mandan refinery in North Dakota and associated MPLX infrastructure.

Sale Recasts Refining Footprint

The agreed purchase price is 4.2 billion US dollars plus inventory value, subject to purchase price adjustments. Marathon Petroleum is to receive 3.45 billion US dollars for the refining assets, while MPLX is to receive 750 million US dollars for related midstream assets.

St. Paul Park has crude processing capacity of 105,000 barrels per calendar day, while Mandan has capacity of 72,000 barrels per calendar day. The associated midstream assets include crude oil pipelines, storage capacity and three terminals.

Capital Moves Toward Core Regions

Marathon Petroleum Chairman, President and CEO Maryann Mannen said the proceeds are intended primarily for Gulf Coast investment. MPLX is also expected to support growth in the Permian and Marcellus basins. For investors, the transaction concentrates the portfolio on regions management considers strategically important, while execution and refining-market conditions remain key variables.

The sale is expected to close by the end of 2026, subject to customary closing conditions, including clearance under the Hart-Scott-Rodino Act. Until completion, the announced portfolio change remains a transaction in progress.
