Marathon Petroleum Q2 FY26 earnings call MPC

Marathon Petroleum reported $8.5 billion in adjusted EBITDA for Q2 FY26, driven by strong market conditions and operational capabilities. The company achieved its lowest level of unplanned downtime this decade, with Gulf Coast refineries running at 100% utilization. R&M margin capture reached 112% in Q2 and 108% year-to-date, reflecting effective crude optimization, feedstock flexibility, and increased clean product yields. The refining macro environment remains constructive, with over 9 million barrels per day of global capacity downtime and tight U.S. gasoline and distillate inventories.

MPLX, MPC's midstream segment, continued to advance its natural gas and NGL growth strategy. Key projects placed into service include the Secretariat I processing plant in April and the Harmon Creek III processing plant in July, increasing total processing capacity to 8.1 billion cubic feet per day. The Blackcomb natural gas pipeline began commissioning in July, with full commercial service expected in Q4. MPLX also plans to expand Permian sour gas treating capacity to over 400 million cubic feet per day by year-end, supporting mid-single-digit adjusted EBITDA growth in 2026 and strong growth in 2027.

MPC returned $2.8 billion of capital to shareholders in Q2, including $2.5 billion in share repurchases, reflecting strong cash generation and adherence to its capital allocation priorities. The company maintains a targeted cash framework of approximately $1 billion, allowing flexibility while supporting capital returns. Management emphasized that the strength of MPLX's distributions enables MPC to lead in capital returns, with MPLX targeting 12.5% annual distribution growth in 2026 and 2027.

The exceptional 112% capture rate in Q2 was attributed to several factors, including strict inventory discipline in a backward-dated market, benefits from crude sourcing and optimization (e.g., SPR exchange barrels, Venezuelan, Canadian heavy, California crudes), favorable impact from derivative unwinds, incremental jet production in a strong margin environment, and high reliability. Management highlighted the use of advanced planning, commercial, and operational competencies, including digital tools, to rapidly adapt to changing market conditions and optimize across integrated value chains.

Following the Martinez turnaround, the Renewable Diesel segment achieved 95% utilization in Q2, contributing to a $277 million year-over-year increase in adjusted EBITDA. This performance was supported by a constructive margin environment, feedstock optimization, and improved regulatory credit values. Management expects a constructive environment through the remainder of the year, noting the market's short RIN balance, but also acknowledged volatility in the RVO market and headwinds to imports.

The West Coast market remains particularly tight, with the Jones Act waiver allowing Gulf Coast movements but not fully offsetting the lack of Asian imports. MPC is well-positioned with its LAR and Pacific Northwest assets to meet consumer demands, especially with competitors facing turnarounds in Q3. The company runs twice as many California-based crudes than normal due to advantaged economics from recent refinery closures in the region.

MPC maintains high crude optionality, capable of running over 100 different types of crudes across its system, with Garyville being the most flexible. While Canadian heavy crudes often offer better economic advantages than Venezuelan barrels, MPC continues to utilize Venezuelan crudes. Management anticipates continued pressure on differentials from increasing Venezuelan barrels and potential additional SPR releases (up to 38 million barrels), which would be a tailwind for feedstock costs. The WCS differential is expected to improve from WTI minus $14/barrel to north of $16/barrel by Q4.
