Who Are the Core Customers of Phillips 66 Company?

Phillips 66 customers include over 7,000 branded outlets in the U.S. under Phillips 66, Conoco, and 76, serving small-to-medium enterprise retail partners who need steady supply contracts, brand equity, and supply logistics.

Phillips 66 commercial customers cover major airlines and logistics fleets buying jet fuel and diesel, plus wholesalers and distributors who aggregate product for regional retailers and bulk buyers.

Phillips 66 serves a mixed base: retail consumers via branded stations and predominantly B2B clients-transportation fleets, petrochemical manufacturers, and energy traders purchasing refined products and feedstocks.

By 2026 Phillips 66 core customers increasingly include low – carbon buyers; its 50 percent stake in Chevron Phillips Chemical (CPChem) ties it to global manufacturers of ethylene and polyethylene, and SAF contracts with airlines grew as SAF production targets rose in 2025.

Phillips 66 customers concentrate around Gulf Coast refineries and Midcontinent terminals where integrated refining and midstream assets cut transport costs; these regions accounted for the majority of refined product throughput in 2025 and drive the company's core customers and commercial customers.

By 2026 the West Coast has the strongest market for Phillips 66 renewable fuels and feedstocks due to aggressive state mandates; internationally, Europe and Asia show high demand for specialty lubricants and needle coke, supporting Phillips 66 B2B clients and industrial customers of Phillips 66 refineries.

Phillips 66 is strongest where midstream scale meets specialty marketing: integrated pipelines, terminals, and processing in the Permian, Gulf Coast, and Midcontinent support fuel customers for transportation fleets and wholesalers; marketing and specialties supplied high-margin volumes that insulated refining earnings in 2025.

Permian Basin crude and NGL growth pushed midstream demand higher in 2025-Phillips 66 expanded gathering and processing to capture this, raising throughput and contract volumes; renewables and renewable diesel demand on the West Coast climbed fastest into 2026, increasing commercial and retail customers for renewable fuels and related supply contracts.

Phillips 66 customers now include buyers of renewable feedstocks and battery-material precursors as the company repurposes assets like Rodeo refinery to produce low-carbon intermediates. By early 2026 Phillips 66 had divested over $3,000,000,000 in non-core assets to fund targeted moves into the green economy while keeping the integrated value chain intact.

Phillips 66 core customers-wholesalers, petrochemical manufacturers, airlines, marine operators, and transportation fleets-remain served by optimized, high-margin refineries and midstream assets. Stable refining cash flow supports dividends and long-term supply contracts for commercial customers and fuel customers for transportation fleets.

Repeat demand comes from entrenched industrial customers and fleet fuel card users, while new renewable-feedstock buyers add diversification. Phillips 66 B2B clients and retail partners benefit from integrated logistics and predictable supply, increasing ecosystem stickiness and contract renewals.

The strongest growth lever is brownfield conversion of existing refining and midstream sites to produce higher-value, lower-carbon products; this preserves capital efficiency and accelerates market entry. For concrete context, Phillips 66 allocated material capital to these conversions while maintaining refining throughput that underpins margins and supplies regional retailers carrying Phillips 66 gasoline-see Leadership and Ownership of Phillips 66 Company.
