What was Marathon Petroleum's first-quarter 2026 refining and marketing margin, and how did it compare to the prior year?

Marathon Petroleum's first-quarter 2026 refining and marketing margin was $17.74 per barrel, up from $13.38 per barrel in the same period last year.

How did geopolitical events in the Middle East contribute to Marathon Petroleum's stronger first-quarter 2026 results?

The Middle East war—specifically the Iran war and the near-closure of the Strait of Hormuz—tightened global fuel supplies, forced output cuts abroad, and boosted U.S. refined products exports to a record high in March, supporting stronger refining margins for U.S. refiners like Marathon Petroleum, which are less reliant on Middle Eastern crude.
