Marathon Petroleum to Sell Two Refineries to CVR Energy for $4.2 Billion

what happened

Marathon Petroleum has agreed to hand over two refineries and related marketing operations to CVR Energy in a transaction valued at $4.2 billion. The package covers the St. Paul Park plant in Minnesota and the Mandan plant in North Dakota, which together process around 177,000 barrels per day. CVR will pay about $3.45 billion for the refining and marketing business, while Marathon's midstream unit MPLX will collect another $750 million for related infrastructure. Inventory is settled separately.

Reuters reported that the purchase will nearly double CVR's refining capacity. Trafigura, a commodity trader, will put $800 million into CVR and sign deals to be the exclusive crude supplier to the acquired plants, while also handling product trading and offtake.

The deal comes as refining profits are unusually strong. Marathon's refining margin in the third quarter more than doubled to $45.70 a barrel, pushing adjusted earnings per share to $26.93 against a $24.47 consensus. Refinery utilization hit 100%. Closing is expected by the end of 2026.

why it matters

For CVR, the acquisition is a major step up in scale, but it brings heavier financing and integration risk. For Marathon, the move looks more like portfolio reshaping, with proceeds steered toward Gulf Coast and midstream projects. Premarket, Marathon shares rose about 2.2% while CVR fell roughly 1.3%.
