Valero Energy operates 15 petroleum refineries across the U.S., Canada, and UK with 3.2 million barrels per day of throughput capacity, making it the world's largest independent refiner. The company converts crude oil into gasoline, diesel, and jet fuel, capturing the crack spread (difference between refined product prices and crude costs). Stock performance is driven by refining margins, utilization rates at Gulf Coast and Mid-Continent facilities, and renewable diesel production from its Diamond Green Diesel joint venture.
EnergyIndependent Oil Refining & Marketinghigh - Refining has substantial fixed costs (maintenance, labor, depreciation) representing 60-70% of total costs. Once throughput exceeds breakeven utilization (~75-80%), incremental barrels generate outsized margin contribution. A $5/barrel improvement in crack spreads can swing annual EBITDA by $3-4 billion given the 3.2M bpd capacity base.
