Winston Score History

The full picture

Sunoco LP (ticker: SUN) is a fuel distribution company based in the United States. It buys gasoline, diesel, and other fuels from refineries and sells them to gas stations, convenience stores, and other businesses that need large amounts of fuel. It is one of the largest motor fuel distributors in the country, supplying fuel to thousands of locations across more than 40 states.

Sunoco makes most of its money by buying fuel at wholesale prices and selling it at slightly higher prices, earning a small margin on each gallon distributed. It also earns revenue from renting fuel storage terminals and pipelines to other companies. Its scale and long-term supply contracts with customers give it a degree of stability, but its thin margins mean profits are sensitive to changes in fuel volumes and wholesale fuel prices. The key long-term risk is the gradual shift toward electric vehicles, which could slowly reduce demand for the gasoline and diesel that make up nearly all of its business.
