AI Summary

Marathon Petroleum refines crude oil into gasoline, diesel, jet fuel, and other products at its 13 refineries, then sells these fuels to gas stations (including Marathon and ARCO brands), airlines, and industrial buyers [EODHD]. The company also operates pipelines, storage terminals, and barges to move oil and refined products around the country, plus a growing renewable diesel business that converts plant oils and waste fats into cleaner-burning fuel [EODHD].

Marathon Petroleum is the largest U.S. oil refiner, operating refineries across the Gulf Coast, Mid-Continent, and West Coast while also running midstream pipelines and renewable diesel operations [EODHD]. The company beat Q1 2026 earnings by 35% thanks to supply disruptions from Middle East conflicts that made refining unusually profitable [Yahoo Finance]. Recent stock performance has been exceptional—up 57% year-to-date and 55% over the past year—though insiders have been selling and one major institutional holder significantly reduced its position [SEC Form 4] [EODHD].

Financially solid with moderate leverage and strong cash generation, though profitability has slipped from prior peaks.
