CVR Energy to Buy Two Marathon Midcontinent Refineries for $4.2 Billion

CVR Energy has agreed to pay about $4.2 billion, plus inventory value, for two Marathon Petroleum Midcontinent refineries — a deal that will lift the Sugar Land, Texas, company's crude throughput capacity from 207,000 b/d to roughly 384,000 b/d overnight.

The agreement, announced with Marathon Petroleum Corp. (MPC) and MPLX LP, covers the 105,000-b/d St. Paul Park refinery in Minnesota and the 72,000-b/d Mandan refinery in North Dakota, along with associated logistics assets and a fuels marketing business. Upon closing, CVR's refining footprint will stretch into the Upper Midwest and Northern Great Plains, deepening its exposure to regional transportation-fuels demand.

What's in the package?

The two plants bring distinctly regional slates. St. Paul Park processes sweet and heavy sour crude and manufactures gasoline, distillates, asphalt, propane, heavy fuel oil, and natural gas liquids and petrochemicals, moving products out by truck, rail, and barge. Mandan runs primarily sweet domestic crude from North Dakota and makes a similar product slate, shipping by truck and rail.

The numbers behind the assets are what caught CVR's eye:

• Average Nelson complexity index of about 7.8 across the two refineries
• Average utilization of 98% during 2023-25, excluding turnaround periods, according to CVR
• More than $1.1 billion of EBITDA generated in the first nine months of 2026
• Interests in a crude oil pipeline, storage infrastructure, and three terminals serving the refineries, held by MPLX

"We are acquiring 2 well-maintained, highly productive refineries from Marathon that have generated more than $1.1 billion of EBITDA for the first 9 months of 2026," said Dane Neumann, president and chief executive officer of CVR Energy. "In light of current favorable market conditions, we expect the acquired business to continue to generate substantial cash flows over at least the next 12 months."

Note the framing: Neumann tied his cash-flow outlook to "current favorable market conditions" — a market view attributed to the buyer, not a forecast baked into the deal itself.

How the money splits

MPC will receive $3.45 billion for the refining and marketing assets. MPLX takes $750 million for the midstream package. In a separate release, Maryann Mannen — chairman, president, and CEO of both MPC and MPLX — said the proceeds will be redeployed "primarily in the Gulf Coast and to support MPLX's growth in the Permian and Marcellus basins."

The read is straightforward: Marathon is rotating capital out of inland refining and toward Gulf Coast projects and Permian and Marcellus midstream growth, while CVR doubles down on inland fuels.

Where the synergies come from

CVR expects to realize about $70 million per year in run-rate synergies, mostly from cuts to selling, general, and administrative costs plus commercial and operational improvements across the combined system.

The fuels marketing platform adds a distribution layer CVR didn't have at this scale — gasoline, ultra-low-sulfur diesel, jet fuel, and asphalt moving through local rack and wholesale channels. CVR said the business will expand distribution opportunities, improve margin optimization across its refining network, and add blending capacity that reduces exposure to volatile Renewable Identification Number (RIN) compliance costs.

The watch item

The companies expect to close the transaction by yearend, subject to customary regulatory approvals and closing conditions.

Until then, the number to track is that $1.1 billion of nine-month EBITDA — whether Midcontinent cracks hold enough through closing for CVR's price to keep looking like a bargain.
