Circle K began with a man named Fred Hervey, who purchased three Kay’s Food Stores in Texas in 1951. He renamed them “Circle K Food Stores, Inc.” and expanded the chain into Arizona and New Mexico. The company continued to grow and by 1975, boasted 1,000 locations across the U.S.
In 1979, the Circle K brand expanded to Japan and by 1990, had over 4,500 stores in 32 U.S. states. In 1996, the company was acquired by Tosco Corporation, and Tosco was purchased by Phillips Petroleum in 2001 (which later became ConocoPhillips). Today, Circle K can be found in Mexico, China, Japan, Macau, UAE, Guam, Hong Kong, Indonesia, and Vietnam. There are no Circle K gas cards available, but the chain does offer gift cards.
