Upside lens

MPC: Garyville, El Paso and Robinson projects can increase production of higher-value fuels and improve refinery economics. Permian and natural-gas infrastructure growth at MPLX can increase stable distributions to MPC. Scale, logistics integration and completed turnaround work can support utilization and capture favorable margins.

PSX: Fractionation, export and pipeline projects can add fee-oriented cash flow. High utilization and clean-product yield can improve margin capture. New polymer capacity can support long-duration growth after startup.

Risk lens

MPC: Crack spreads and crude differentials can change rapidly and materially affect refining earnings. Unplanned outages or cost overruns during major maintenance can reduce throughput and increase expenses. Fuel standards, emissions rules and legacy remediation obligations can require significant spending.

PSX: Crack spreads, differentials and outages can rapidly change earnings. Derivative timing and accounting can create large reported swings. Large projects face cost, schedule and startup risks.
