What was the primary driver of the significant increase in net income in the first quarter of 2026 compared to the first quarter of 2025?

The primary driver was a substantial increase in net income attributable to MPC, rising from a loss of $74 million in Q1 2025 to a profit of $511 million in Q1 2026. This was largely fueled by an increase in total revenues and other income by $2.72 billion, driven by higher sales and other operating revenues, as well as improved refining margins in the Refining & Marketing segment.

How did the company's share repurchase program evolve during this period?

MPC continued its share repurchase activities, with $750 million used in Q1 2026, compared to $1.06 billion in Q1 2025. As of March 31, 2026, $3.63 billion remained under the existing authorization. Importantly, on May 5, 2026, the company announced an additional $5.0 billion share repurchase authorization, signaling ongoing confidence in capital returns to shareholders.

What is the outlook for the Refining & Marketing segment, and what factors are influencing its performance?

The outlook for the Refining & Marketing segment appears constructive. Performance is driven by refining margins, which saw a significant increase in Q1 2026 due to favorable market conditions. The company expects global demand growth to outpace refining capacity additions, supporting U.S. refiners. Key influences on margins include crack spreads, crude oil differentials, and the cost of RINs.

How is MPC managing its liquidity, and what are its financial resources?

MPC's liquidity position is robust. As of March 31, 2026, MPC (excluding MPLX) had total liquidity of $5.64 billion, including $4.99 billion available under its revolving credit facility. Net cash provided by operating activities was $1.12 billion in Q1 2026, a significant improvement from a net cash used of $64 million in Q1 2025. The company believes its liquidity is adequate to fund its operations, capital programs, share repurchases, and other obligations.
