Sunoco is a large-scale fuel distributor and energy infrastructure operator. Its core business is buying motor fuel in bulk from refiners and reselling it to roughly 9,200 dealer and distributor sites, 1,300 commission agent locations, 330 company-operated convenience stores, and over 13,000 commercial customers across the U.S., Canada, and the Greater Caribbean — distributing over 15 billion gallons annually. Sunoco earns a per-gallon margin on fuel it sells outright to dealers under long-term supply contracts, retains retail pricing exposure on fuel sold through commission agent sites, and generates merchandise revenue at company-operated stores. Beyond fuel distribution, Sunoco operates roughly 6,000 miles of refined product pipeline, 6,000 miles of crude oil pipeline, and over 150 terminals across North America, Europe, and the Caribbean, which generate more stable fee-based throughput and storage revenue. Sunoco also operates the Burnaby Refinery in British Columbia, which processes about 55,000 barrels per day of crude into gasoline, diesel, and jet fuel for the BC market. Because fuel is a commodity, per-gallon margins are thin, and profitability depends on volume and logistics scale. Sunoco has been expanding aggressively through acquisitions, most notably its 2025 acquisition of Parkland, which added Canadian and Caribbean operations and the Burnaby Refinery, and a 2026 acquisition of 16 terminals in Germany and Poland. Sunoco is a limited partnership controlled by Energy Transfer.
