    Highlights

    5

    • Delivered strong cash generation of $2.4 billion in Q3 FY25.

    • Refinery utilization was 95% in Q3 FY25, with planned turnarounds executed safely and on time.

    • Achieved a year-to-date capture rate of 102%, up from 95% in the prior year.

    Concerns

    3

    • Q3 FY25 capture rate was 96%, softer than the prior quarter's 105%, primarily due to West Coast dynamics and Galveston Bay RHU downtime.

    • Renewable diesel facilities operated at 86% utilization with weaker margins in Q3 FY25, driven by higher feedstock costs.

    • Share repurchases in Q3 FY25 were $650 million, lower than some analyst models, though management reiterated commitment to buybacks.

    Segment performance

    3
    SegmentRevenueYoYQoQMargin
    Refining & Marketing
    Strong results with several refineries achieving monthly throughput records (Robinson, Detroit, Anacortes). Mid-Con margins strengthened sequentially, but were offset by declining margins in the U.S. Gulf Coast and West Coast. Headwinds included jet to diesel differential compression, lower clean product margins, inventory changes, and Galveston Bay RHU downtime (almost 2% system-wide impact).

    MPLX is executing its growth strategy, targeting natural gas and NGL value chains, and remains a source of durable cash flow growth for MPC. MPLX increased its distribution this quarter, reflecting conviction in its growth outlook.

    Risks & headwinds

    West Coast market dynamics impacting captureQ3 FY25

    clean product margins fell about 40%; jet premium to diesel narrowed from benefit to negative; secondary product margins were a headwind

    Mitigation: LAR project coming online in Q4 to meet NOx reduction and improve efficiency; optimizing Anacortes and Kenai to fill San Francisco short; significant feedstock advantage with local California crude.

    headwind to capture of almost 2% across the whole system with a larger effect on Gulf Coast results

    Mitigation: Expected to be at full operating capacity before the end of November.

    Weaker Renewable Diesel marginsQ3 FY25

    higher diesel prices and RIN values were more than offset by higher feedstock costs

    Mitigation: Continue to optimize renewable operations, leveraging logistic and pretreatment capabilities; no significant capital investment in this space.

    Unprecedented volatility in jet-to-diesel differentialQ3 FY25

    caused an imbalance for 1-1.5 months

    Mitigation: Differential has corrected itself and is not seen as structural.

    potential 50% limitation

    Mitigation: Strong logistics for international and domestic feedstock at Martinez, providing ability to pivot; less of an impact for MPC but broader market impact.

    Q&A highlights

    8

    Why was the Q3 capture rate softer than expected, and what is the company's outlook on the pace of share repurchases?

    Q3 capture of 96% was primarily driven by West Coast dynamics (40% fall in clean product margins, narrowed jet-to-diesel differential) and Galveston Bay RHU downtime. Management reiterated commitment to share buybacks as the primary return of capital, noting no change in strategy and that the pace can vary quarter-to-quarter, supported by growing MPLX distributions.

    “No change, Neil, in our ability to continue to lead in share repurchase, no change in the way we view it. And it will be, as you know, the primary return of capital going forward.”

    Detailed Narrative

    01

    Leadership Transition and Recognition

    CEO Maryann Mannen recognized Mike Hennigan, Executive Chairman, who will be stepping down at the end of the year. She thanked him for his tremendous guidance and contributions to the Board and leadership team. This marks a significant leadership change for the company.

    02

    Capital Allocation Strategy

    MPC returned over $900 million to shareholders in Q3 FY25, including $650 million in share repurchases and $276 million in dividends. Year-to-date, $3.2 billion has been returned. The company announced a 10% dividend increase, marking the third consecutive year of 10% growth, supported by declining share count and growing distributions from MPLX. Management reiterated its commitment to share buybacks as the primary return of capital, but stated it would not take on debt for this purpose.

    03

    West Coast Market Dynamics

    The West Coast was a primary driver of the sequential decline in capture rates in Q3 FY25, with clean product margins falling approximately 40% and the jet premium to diesel narrowing. However, management expressed bullishness on the West Coast outlook, citing a current $40 crack spread, recent refinery closures, and MPC's competitive advantage with its Los Angeles, Anacortes, and Kenai assets. The LAR project, coming online in Q4, is expected to further strengthen competitiveness and meet NOx reduction requirements. MPC is also leveraging a significant feedstock advantage by increasing local California crude purchases.

    04

    Renewable Diesel Optimization

    Renewable diesel facilities operated at 86% utilization in Q3 FY25, showing improved operational reliability. However, margins were weaker due to higher diesel prices and RIN values being offset by increased feedstock costs. MPC is focused on optimizing existing operations and leveraging logistics, but is not planning significant new capital investments in this space due to regulatory uncertainty🌐 and market volatility🌐. The company is well-positioned to pivot feedstock sourcing due to strong logistics at Martinez.

    05

    Midstream Growth and Strategic Acquisitions

    MPLX's Midstream segment adjusted EBITDA increased 5% year-over-year in Q3 FY25. MPLX acquired a Delaware Basin sour gas treating business and the remaining 55% interest in the BANGL NGL pipeline, enhancing its growth profile. These acquisitions, along with other projects like the Secretariat processing plant and future fractionation facilities, are expected to drive incremental EBITDA and support MPLX's targeted 12.5% distribution growth rate over the next couple of years, which will significantly benefit MPC's cash flow.

    06

    Market Outlook and Commodity Spreads

    Management believes current market fundamentals, characterized by supply tightness and supportive demand, will persist into 2026. October blended crack spreads were over $15 per barrel, seasonally strong and 50% higher year-over-year. Diesel and jet demand are up modestly, while gasoline is flat to slightly lower. The company noted unprecedented🌐 volatility in the jet-to-diesel differential in Q3, but expects it to normalize. Favorable dynamics are observed in crude differentials, with ASCI prices $2 weaker than earlier in the year and offshore production increasing, providing a tailwind for MPC.
