CST

Cst Brands Inc

A retailer of fuel and convenience stores headquartered in San Antonio, Texas, best known for its Corner Store stations across the US and English-speaking Canada, with French-speaking locations going by Dépanneur du Coin. It was born in 2013 when refiner Valero Energy spun off its retail operations, and its name "CST" is shorthand for Corner Store, the name it first filed under. The chain was later bought by Canadian convenience giant Alimentation Couche-Tard in 2017.
