Direct Answer
Phillips 66 (PSX) is a diversified downstream energy company spun off from ConocoPhillips in 2012. PSX operates refineries that convert crude oil into fuels, owns NGL midstream infrastructure, holds a 50% stake in Chevron Phillips Chemical Company (CPChem), and sells refined products through branded retail and wholesale channels. Unlike pure exploration and production companies, PSX does not produce crude oil -- it buys it and converts it into higher-value products.

What Does Phillips 66 Do?
PSX converts crude oil into fuels and chemicals across its refinery network, transports and fractionates natural gas liquids through its midstream assets, and manufactures petrochemicals through CPChem. The business is diversified across downstream energy segments: when refining margins are weak, chemicals or midstream may offset some of the shortfall, though all are affected by broader energy market conditions.
Frequently Asked Questions
What does Phillips 66 do and how does it make money?
Phillips 66 operates across four segments of the downstream energy value chain. Refining: PSX refines crude oil into gasoline, diesel, jet fuel, and other petroleum products at refineries in the US and Europe; profitability is driven by the crack spread (the difference between refined product prices and crude oil input costs). Midstream: PSX has significant NGL (natural gas liquids) gathering, processing, fractionation, and transportation infrastructure, partly through its stake in Phillips 66 Partners LP (which it later acquired fully). Chemicals: PSX owns 50% of Chevron Phillips Chemical Company (CPChem), a large petrochemicals joint venture with Chevron that produces ethylene, polyethylene, and other chemicals. Marketing and Specialties: PSX sells refined products through wholesale and branded retail channels, and produces specialty petroleum products.
How was Phillips 66 formed and what is its history?
Phillips 66 was created in 2012 when ConocoPhillips split into two companies: ConocoPhillips (retaining upstream exploration and production) and Phillips 66 (receiving the downstream refining, midstream, chemicals, and marketing businesses). ConocoPhillips made this separation because E&P and downstream/refining businesses have different risk profiles, valuation methodologies, and capital allocation frameworks -- separating them allowed each business to be valued and managed on its own merits. The Phillips 66 name and the 66 brand were retained from the legacy Phillips Petroleum Company, which had merged with Conoco in 2002 to form ConocoPhillips.
What is CPChem and why is it valuable to PSX?
Chevron Phillips Chemical Company (CPChem) is a 50/50 joint venture between Phillips 66 and Chevron Corporation. CPChem is one of the world's largest producers of ethylene (from the US Gulf Coast advantaged ethane feedstock) and polyethylene (used in packaging, pipes, and consumer products). CPChem benefits from the US shale revolution's output of low-cost ethane, giving it a feedstock cost advantage over naphtha-based crackers in Europe and Asia. CPChem's US Gulf Coast ethylene facilities can run at very low feedstock costs, producing attractive margins when global polyethylene prices are firm. CPChem occasionally undertakes major capital projects -- new ethylene crackers -- which are multi-billion dollar investments with long construction timelines but create scale advantages once operational.
How does refining profitability work for Phillips 66?
A refinery's profit depends primarily on the crack spread -- the difference between the market price of refined products (gasoline, diesel, jet fuel) and the cost of crude oil inputs. When crack spreads are wide (product prices high relative to crude), refiners make high margins; when spreads compress (product prices fall relative to crude, or crude costs rise faster), margins fall. Crack spreads are affected by refined product demand (driving activity, air travel, industrial fuel use), crude oil supply and pricing, refinery utilization rates across the industry, and seasonal patterns (gasoline demand peaks in summer, heating oil in winter). PSX's refinery fleet includes complex refineries capable of running heavy, sour crude (typically cheaper) and producing a high yield of high-value light products, which provides a margin advantage over simpler refineries.
What are the main risks for Phillips 66?
Key risks include refining margin cyclicality (crack spreads can compress sharply, turning refining from highly profitable to near breakeven or loss-making; this happened during COVID when demand collapsed), energy transition risk (long-term demand for gasoline and diesel may decline as electric vehicles penetrate the market, potentially stranding refinery assets), crude oil price exposure (PSX must buy crude oil and sell products; extreme crude price volatility can disrupt working capital and margins), chemicals cycle exposure (CPChem's polyethylene margins are also cyclical; new global capacity additions can oversupply the market), and regulatory and environmental risk (refineries are subject to extensive environmental regulations; stricter requirements for clean fuels or carbon pricing could increase operating costs).
