The company was created on May 1, 2013, when Valero Energy Corporation decided to spin off its retail operations in an effort to focus on refining. On August 6, 2014, CST Brands agreed to buy Lehigh Gas GP LLC, the general partner of Lehigh Gas Partners LP (LGP), from Lehigh Gas Corp in a cash and stock deal. CST Brands will also acquire the associated Incentive Distribution Rights of LGP. The deal closed on October 1, 2014 and LGP changed its name to CrossAmerica Partners LP, trading under the ticker symbol "CAPL".
On August 22, 2016, Alimentation Couche-Tard, parent company of Circle K, entered a merger agreement with CST to acquire their over 1000 Corner Store locations in an all cash deal worth $4.4 billion, including net debt assumed. The transaction officially closed on June 28, 2017. Stores under the former Corner Store brand will be converted and remodeled to the Circle K brand. As of June 2018, CST Store rebranding has begun in San Antonio, TX and surrounding areas.
CST operates over 1,000 Corner Store convenience store locations in the United States, including Texas, Louisiana, Arkansas, Oklahoma, New Mexico, Colorado, Wyoming, Arizona and California. On November 4, 2014 it was announced that CST Brands would acquire assets of Nice N Easy Grocery Shoppes, a New York-based company with over 30 company operated stores in its network.

The network includes 80 card lock sites located along natural trucking routes or industrial parks that allow trucking and commercial fleets to buy fuel 24 hours a day. Following the 2016 purchase of CST by Couche-Tard, its Ultramar operations were acquired by Parkland Fuel Corporation.
