History
The first Thorntons location opened in 1971 in Clarksville, Indiana. The original site featured a kiosk building and a full-service attendant. In the 1980s, Thorntons transitioned from kiosk locations to convenience stores and grew to over 100 locations.

In 2013, Thorntons introduced a larger store model with an expanded food program in select Louisville, Kentucky and Southern Indiana stores. In 2016, this platform was expanded in select Chicago metropolitan area stores.

Around the same time frame, Thorntons rolled out Unleaded15 fuel which provides an octane rating of 88 and contains approximately 15% ethanol. Certain Thorntons locations also offer E85.

In 2019, Thorntons was acquired by a joint venture between Arclight Capital Partners and BP. In July 2021, BP agreed terms to acquire ArcLight Capital Partners' shareholding. The transaction was completed on August 31, 2021. BP retained the Thorntons brand, making it a sister chain to BP-owned ampm; the two chains do not overlap.
