Marathon Petroleum stock: $4.2 billion sale redirects capital

Marathon Petroleum agreed on November 3, 2026, to sell its St. Paul Park and Mandan refineries and related midstream assets to CVR Energy for 4.2 billion US dollars, according to Reuters. The transaction redirects capital toward Marathon Petroleums Gulf Coast portfolio as the refiner reassesses its Mid-Continent assets.

Strong margins lift third-quarter results

Adjusted diluted earnings reached 26.93 US dollars per share in the third quarter, ahead of the 24.47 US dollar analyst estimate cited by LSEG. The refining and marketing margin more than doubled from a year earlier to 45.70 US dollars per barrel, while crude capacity utilization reached 100 percent.

Throughput rose to 3.2 million barrels per day from 3.0 million barrels per day a year earlier. The strong operating backdrop gives the company more capital flexibility, but it also raises the comparison base for coming quarters.

Asset sale shifts capital allocation

Marathon Petroleum expects to receive 3.45 billion US dollars from the refinery portion of the transaction. Its midstream subsidiary MPLX is set to receive 750 million US dollars for related infrastructure. The two refineries have combined crude processing capacity of 177,000 barrels per day, and the transaction is expected to close by the end of 2026.

Marathon Petroleum plans to reinvest its proceeds primarily along the US Gulf Coast. MPLX intends to direct its share toward growth projects in the Permian and Marcellus basins. The allocation supports a more concentrated portfolio, while closing and execution remain important conditions for the planned investment.

Lower throughput sets next test

Management expects total refinery throughput of 3.08 million barrels per day in the fourth quarter, below the third-quarter level. Planned work could limit the ability to upgrade certain products and capture available margins, making utilization and refining spreads the next operating focus.

Marathon Petroleum stock traded at 342.20 euros on Lang & Schwarz at 2:38 p.m. CET on Tuesday, November 10, 2026.
