Marathon Renewable Diesel Earnings Climb in Q3
Marathon Petroleum's renewable diesel segment posted sharply higher third-quarter revenue and adjusted EBITDA compared with a year earlier.
Updated on Nov. 4, 2026 in Oil and Gas
Marathon Petroleum reported that its renewable diesel segment swung to strong profitability in the third quarter, with adjusted EBITDA of $254 million compared with a $56 million loss a year earlier. Segment revenue rose to $1.368 billion from $716 million over the same period.
Why it matters
The improvement reflects a stronger margin environment, higher regulatory credit values and greater throughput, showing how policy-linked credits and feedstock flexibility can shift the economics of renewable fuel production. For the United States, where renewable diesel plants in North Dakota and California are part of the domestic fuel supply, the results illustrate how the sector's profitability depends heavily on credit values and market conditions.
Renewable diesel production rose roughly 1% from Q3 2025 while the facilities ran at 89% capacity, and nine-month adjusted EBITDA reached $550 million versus a $117 million loss a year earlier. The extraction does not say how much of the improvement is expected to persist into future quarters.
The players
Marathon Petroleum
Marathon Petroleum is one of the largest refiners in the United States, operating refining, logistics and renewable fuels businesses across the country.
Neste
Neste is a Finnish renewable fuels company that is a major global producer of renewable diesel and sustainable aviation fuel.
The details
Marathon operates two renewable diesel plants, in Dickinson, North Dakota, and Martinez, California, with the Martinez biorefinery run through a joint venture with Neste. The company said it is leveraging feedstock and logistics flexibility to adapt to market conditions, and it expects the segment to run at 85% capacity utilization in the fourth quarter.
Timeline
Q3 2025: Baseline quarter against which the 2026 third-quarter results are compared.
November 3, 2026: Marathon reported its third-quarter renewable diesel earnings.
Q4 2026: Renewable diesel segment expected to operate at 85% capacity, and a planned turnaround is scheduled at the Dickinson facility.
Market Landscape
The swing from a $56 million loss to a $254 million gain places Marathon's renewable diesel results in sharp contrast with the weak 2025 margins that preceded them. The comparison shows how quickly the segment's profitability has moved with changes in margins and credit values across the industry.
Shifts in renewable diesel margins and regulatory credit values can influence the price and supply of diesel and other fuels that households and fleets rely on. Consumers may see these effects indirectly through fuel pricing, though the extraction does not quantify any specific retail impact.
The takeaway
Renewable diesel profitability can swing sharply within a year, so tracking regulatory credit values and margin conditions is key to understanding the sector's results. Readers following fuel markets should watch fourth-quarter utilization and any changes to credit policy.
What happens next
Marathon is expected to run its renewable diesel facilities at 85% capacity in the fourth quarter, and a planned turnaround at the Dickinson plant is scheduled for that quarter.
