Marathon’s Refinery Deal with CVR Valued at $4.2 Billion Gives MPLX a $750 Million Stake

Key Facts

Marathon Petroleum and MPLX announced a definitive agreement on November 3 to sell the St. Paul Park and Mandan refineries, along with related logistics assets, to CVR Energy for $4.2 billion plus the value of inventory. Marathon is selling the refining assets, while MPLX is selling logistics assets that support the refineries’ operations; therefore, the full deal value does not go to MPLX. Under the joint announcement, Marathon will receive $3.45 billion before inventory, while MPLX’s share is $750 million. The price is subject to deal-related adjustments, and the sale remains subject to customary closing conditions and regulatory approvals. The deal reshapes refining and logistics assets in Minnesota and North Dakota, while positioning CVR to expand its capacity and marketing outlets.

The assets include the St. Paul Park refinery in Minnesota, with crude oil processing capacity of 105 thousand barrels per day, and the Mandan refinery in North Dakota, with capacity of 72 thousand barrels per day. CVR said the refineries averaged utilization of 98% during 2023–2025, excluding turnaround maintenance periods, and have an average complexity rating of about 7.8. The deal also includes an integrated marketing platform supplying up to 590 branded locations in the Upper Midwest and Northern Great Plains. MPLX’s logistics package includes an interest in a crude oil pipeline, storage capacity and three terminals serving the refineries’ operations. MPLX valued the sale of the logistics assets at 9 times projected 2027 EBITDA.

For CVR, the acquisition would raise crude oil processing capacity from about 207 thousand barrels per day to about 384 thousand, according to the company’s estimates. CVR expects annual run-rate synergies of about $70 million. The company said the acquired businesses generated about $1.2 billion in EBITDA during the twelve months ended September 30, 2026, amid favorable market conditions at the time. On a pro forma basis for the nine months ended on the same date, CVR said EBITDA would have risen from about $900 million on a standalone basis to about $2 billion after accounting for the deal. These figures link the expected impact to reported results and assume completion of the acquisition, while the marketing platform adds a distribution channel alongside the refineries.

Marathon and MPLX plan to reinvest the capital proceeds from the deal mainly on the Gulf Coast, allocating them to support MPLX’s growth in the Permian and Marcellus basins. This represents a stated plan to redirect investment toward those basins and related infrastructure projects. In its third-quarter 2026 results, adjusted EBITDA attributable to MPLX was about $1.859 billion, compared with $1.766 billion in the same quarter of 2025, a year-over-year increase of 5.3%. The company’s chief executive said MPLX expects mid-single-digit growth in adjusted EBITDA as utilization rises and key growth projects enter service. The sale announcement accompanies this strategy, giving the company cash proceeds from logistics assets that serve the refineries.

CVR expects to finance the deal, including related fees and expenses, through a mix of $2.5 billion in committed secured debt financing, a $500 million equity contribution commitment from its controlling shareholder, an $800 million equity investment from Trafigura, and available cash. The structure combines debt, shareholder commitments and outside investment, according to CVR’s disclosure. The announcement did not say the deal expands CVR’s transportation business; it identified the acquired assets as two refineries and a marketing platform, along with the related logistics assets being sold by MPLX. MPLX’s proceeds remain separate from the consideration allocated to Marathon’s refining assets. EL7 data show CVI shares closed at $48.6 on November 3, while MPLX shares closed at $57.5 on the same day.

The deal is expected to close by the end of 2026, subject to customary closing conditions and regulatory approvals, including the expiration or termination of the waiting period under the Hart-Scott-Rodino Act. Until closing, the transfer of ownership of the refineries and logistics assets remains subject to those conditions. After the divestiture, Marathon expects to continue operating a refining system with total capacity of about 2.8 million barrels per day. MPLX says rising utilization and key growth projects entering service support its expectation of mid-single-digit growth in adjusted EBITDA. The companies have set a year-end closing target, with regulatory approvals remaining among the announced conditions.
