Commodity Price Volatility Impacts: Exposure to fluctuating prices for crude oil, refined products, and natural gas significantly impacts profitability and cash flows, especially for refining margins.

Regulatory & Environmental Compliance Risks: Strict and evolving environmental regulations, including renewable fuel standards and greenhouse gas emissions targets, can increase operating costs, require significant capital expenditures, and lead to potential fines.

Operational Incident & Safety Hazards: The inherent risks of operating complex refining and pipeline assets, including potential for fires, explosions, spills, and equipment failures, can result in injuries, fatalities, property damage, and significant financial and reputational harm.
