About
Phillips 66 is a Houston, Texas-based diversified energy manufacturing and logistics company — publicly traded on the New York Stock Exchange (NYSE: PSX) as an S&P 500 Energy component — operating 13 refineries with 2.2 million barrels-per-day capacity, midstream pipeline and NGL infrastructure, retail fuel brands, a chemicals joint venture, and a renewable fuels facility through approximately 14,000 employees. In fiscal year 2024, Phillips 66 generated $145.5 billion in revenue, though Q4 2024 earnings fell to $8 million versus $346 million in Q3 2024 (adjusted loss of $61 million) due to refining margin compression from the spread between crude oil input costs and refined product prices.

In 2024, Phillips 66 divested its 65% stake in German and Austrian retail operations for $1.6 billion and announced closure of its Los Angeles Refinery.
