Alimentation Couche-Tard, though in September 2021 these stores went unbranded, officially retiring the Dairy Mart name. Circle K retains a large presence in Ohio to this day due to the enduring legacy of Lawson's, especially in Northeast Ohio and Columbus, primarily competing with Speedway. However, many of the former Lawson's stores under Dairy Mart in Pennsylvania closed during the late 1990s, and only a few survived by the time Circle K took over the locations.
