VLO: Oil and Gas Refining and Marketing

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.

VLO: System optimization and high throughput can allow Valero to capture favorable product margins and crude differentials. The FCC optimization project can increase the refinery's ability to produce higher-value products after startup. Improved renewable diesel and ethanol economics can diversify earnings beyond conventional refining.

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.

VLO: Refining profitability can fall quickly when product margins narrow or crude discounts compress. Refinery outages, accidents and severe weather can reduce throughput and create repair or liability costs. Renewable diesel and ethanol returns depend on volatile feedstock costs, credits and government fuel policy.
