BP America’s national convenience-store brand is La Palma, Calif.-based ampm, a fully franchised banner on the West Coast.

The ampm brand’s key focus is foodservice, with a program that emphasizes coffee, bakery, fresh sandwiches and hot prepared foods. A large fountain program offers up to 24 varieties of soda and proprietary drinks. Stores have an open floor plan, with some featuring open-air refrigerated cases carrying a selection of fresh sandwiches, fruit and yogurt.

A new joint venture between London-based BP and ArcLight Capital Partners closed on the acquisition of Louisville, Ky.-based Thorntons Inc. in February 2019. BP took full ownership of Thorntons in 2021, removing the chain from the Top 202 list (No. 38 in 2021) and adding it to BP’s total store count.

For benchmarking purposes, store counts are as of Jan. 1, 2022.
