Marathon Petroleum, the largest US oil refiner, reported third-quarter net income of $7.4 billion on 3 November, up from $1.4 billion a year earlier, and agreed to sell two Midwest refineries to Carl Icahn-controlled CVR Energy for $4.2 billion. Both moves come from the same source: refining margins that have more than doubled during this year’s oil supply shock.
Marathon Petroleum Q3 results: the numbers
According to Marathon’s results release, the main figures compare with the same quarter of 2025 as follows:
| Measure | Q3 2026 | Q3 2025 |
|---|---|---|
| Net income attributable to Marathon | $7.4 billion | $1.4 billion |
| Diluted earnings per share | $26.59 | $4.51 |
| Adjusted earnings per share | $26.93 | $3.01 |
| Adjusted EBITDA | $11.7 billion | $3.2 billion |
| Refining and marketing margin | $45.70 a barrel | $17.60 a barrel |
| Crude capacity utilisation | 100% | 95% |
Adjusted earnings beat the analyst average of $24.47 a share compiled by LSEG, Finimize reported. Refining and marketing produced $9.9 billion of the $11.7 billion adjusted EBITDA. The company said the main driver was higher crack spreads, the gap between crude prices and fuel prices, across all its regions, ad-hoc-news noted.
Marathon returned $3.3 billion to shareholders in the quarter, raised its quarterly dividend by 10% and approved a new $5 billion buyback, giving it about $8.1 billion of authorisation. Its pipeline affiliate MPLX raised its distribution by 12.5%. Marathon ended September with $13.6 billion of cash and short-term investments.
The $4.2 billion refinery sale to CVR Energy
Marathon and MPLX will sell the St. Paul Park refinery in Minnesota, with 105,000 barrels a calendar day of crude capacity, and the Mandan refinery in North Dakota, with 72,000 barrels a day, plus a crude pipeline interest, storage and three terminals, according to the companies’ deal announcement. The split is:
- Marathon: $3.45 billion for the refining assets, plus inventory value. It plans to reinvest mainly on the US Gulf Coast.
- MPLX: $750 million for the midstream assets, which it says is nine times their forecast 2027 EBITDA.
The deal needs US antitrust clearance and is expected to close at the end of 2026. Afterwards Marathon will have about 2.8 million barrels a day of refining capacity.
For CVR, the deal is large. Its crude capacity would rise from about 207,000 to 384,000 barrels a day, and it gains a marketing business supplying up to 590 branded fuel stations, according to Business Model Analyst’s summary of CVR’s announcement. BigGo Finance reports that the assets earned about $1.2 billion of adjusted EBITDA in the twelve months to 30 September and that CVR expects about $70 million a year of synergies. Icahn controls about 71% of CVR, BigGo says.
Business Model Analyst reports that CVR plans to fund the purchase with $2.5 billion of committed secured debt, $500 million of equity from its controlling shareholder, $800 million of equity from commodity trader Trafigura, and cash. It also notes that the assets earned $506 million of EBITDA in all of 2025, far below the recent run rate.
Why it happened: wartime refining margins
Disruption to oil supply around the Strait of Hormuz has kept crude and fuel prices high this year, and fuel prices have risen faster than crude. Prices remain volatile, as we reported in our latest Brent oil update. Big integrated companies have also benefited: Exxon and Chevron reported refining-led profit gains last week.
The sale shows two views of the same margins. Marathon is turning part of an unusually strong but volatile earnings stream into cash now. CVR is betting that margins stay high long enough to pay down new debt. Finimize noted that current margins reflect supply disruptions that could ease. That is the main risk for a buyer paying a price based partly on 2026 earnings.
Investors have already priced in much of the boom. CVR shares are up more than 120% this year and Marathon’s about 165%, and both rose in pre-market trading after the announcement, BigGo reported. Marathon was about 1.7% higher in early German trading, according to ad-hoc-news.
What it means for India and other businesses
The same margins have lifted Indian refiners. IOC, BPCL and HPCL reported a combined Q2 profit of ₹30,106 crore, and the government has responded with a higher diesel export duty. Marathon’s results suggest the margin strength was global, not local, in the September quarter. Whether it lasts depends mainly on how quickly supply through the Gulf normalises.
Who is more or less exposed
- Buyers of refining assets financed with debt: most exposed if margins fall back towards 2025 levels.
- Sellers taking cash now: less exposed to a fall in margins, but give up future earnings if margins stay high.
- Fuel-heavy businesses such as airlines, logistics and chemicals: high crack spreads raise their fuel costs even when crude prices ease.
- Export-oriented refiners, including in India: benefit from high product prices, but face policy responses such as export levies.
Scenarios to watch
These are conditional scenarios, not predictions.
| If… | Then a likely consequence is… |
|---|---|
| Gulf supply normalises and crack spreads fall | Refiner earnings would drop sharply, and CVR’s debt-funded purchase would look more expensive against lower earnings. |
| Disruption continues into 2027 | Refiners would keep generating high cash flows, supporting more buybacks, dividends and asset deals. |
| US antitrust review raises concerns about regional fuel supply | Closing could be delayed beyond the end of 2026. |
| Other refiners follow Marathon in selling smaller plants | More refining assets could change hands while prices are supported by high margins. |
What to watch next
- Marathon’s fourth quarter, for which it guided lower throughput of 3.08 million barrels a day and $230 million of turnaround costs.
- Hart-Scott-Rodino clearance and the deal’s closing at the end of 2026.
- Results from other refiners, and Brent and diesel crack spreads.
- Details of CVR’s financing as it is finalised.
Bottom line
Marathon Petroleum’s $7.4 billion quarterly profit and $4.2 billion refinery sale show how much the oil shock has raised refining earnings. Marathon is taking some of those gains as cash. CVR, backed by Icahn and Trafigura, is betting they last. For Indian refiners and fuel users, the key question is the same one: how long margins this high can continue.
Method note: we compared Marathon Petroleum’s third-quarter results release and the Marathon/MPLX deal announcement with reports from Finimize, ad-hoc-news, Business Model Analyst and BigGo Finance. CVR’s capacity, financing and 2025 earnings figures come from Business Model Analyst’s summary of CVR’s announcement; trailing EBITDA of about $1.2 billion is consistent between BigGo ($1.2 billion) and Business Model Analyst ($1.158 billion). We could not read CVR’s own release directly. Analyst ratings and price targets were deliberately left out.
