Marathon Petroleum Corporation (MPC)

The company now

Marathon Petroleum, which runs the largest refining system in the United States, earned $5.1 billion in the second quarter of 2026, against $1.2 billion a year earlier 1. Its refining margin, what it keeps on each barrel between the crude it buys and the fuel it sells, rose to $36.33 from $17.58 1. The company said higher crack spreads, the gap between fuel and crude prices, in all regions drove the result 1.

Reuters reported that prolonged disruptions to crude supplies through the Strait of Hormuz doubled refining margins, as the Iran war upset global energy shipping 10. The company's quarterly report ties the higher fuel prices to crude supply disruptions from regional conflicts, particularly in the Middle East 2. Rivals Valero Energy and HF Sinclair also posted their highest quarterly profits since 2022, Reuters reported 10.

The company returned $2.8 billion to shareholders in the quarter, and its board added a further $5.0 billion share repurchase authorization in May 12. In its newest filing, BlackRock reported holding 7.9 percent of the common stock 13. The next marker is the third-quarter results call the company has scheduled for 3 November 2026 11.
