Overview

Clark Brands is an American petroleum and fuel-retailing brand associated with gasoline stations, fuel marketing, and convenience-store operations. Its corporate history traces back to Emory T. Clark, who established a single filling station in 1932 at the corner of 60th Street and Greenfield Avenue in West Allis, Wisconsin. Operating initially as Clark Super Gas, the business sold premium gasoline and followed a distinctive operating model: unlike many service stations of the period, its locations did not provide mechanical maintenance or tire-changing services. The company expanded from retailing into refining in 1943. By the middle of the 1950s, it operated almost 500 stations across the American Midwest and had also established a presence in California and Florida, in addition to Illinois, Indiana, Iowa, Michigan, Minnesota, Missouri, Ohio, and Wisconsin. From 1948 through 1950, the business also sponsored the Milwaukee Clarks, a minor-league ice hockey team competing in the International Hockey League, linking the fuel brand to regional sports promotion. Clark reached its greatest scale during the 1970s, when Clark Oil was described as the largest independent oil refiner and marketer in the Midwest. At that point the company operated 1,489 stations and two refineries, located in Blue Island and Hartford, Illinois. Its stations reportedly sold approximately twice the national-average volume of gasoline, while its emphasis on premium fuel supported relatively high margins. The business therefore combined refining, wholesale fuel marketing, and a large branded retail network rather than functioning solely as a local filling-station chain. Emory T. Clark sold his interest in the company to Apex Oil in 1981. Apex subsequently placed Clark Oil on the market in 1985, and Clark and Apex entered bankruptcy by 1987. In 1992, a division of Toronto-based Horsham Corp. acquired Clark Oil and Refining, including the two refineries and approximately 1,000 stations. The company was renamed Clark Refining and Marketing. Under subsequent ownership changes involving TrizecHahn, The Blackstone Group, and Occidental Petroleum, the business expanded its refining portfolio, including acquisitions of a Lima, Ohio refinery from BP and a Port Arthur, Texas refinery from Chevron. In 1999, the retail division was sold and the remaining company was rebranded as Premcor. A number of Clark stations in southeastern Michigan later closed permanently, including many closures in 2001. The modern Clark Brands organization was formed in 2003 as Clark Brands, LLC. It acquired the Clark name from bankrupt Clark Retail and other parts of the former Clark business, with a primary focus on licensing the Clark brand to independent operators rather than owning and directly operating every branded station. This model allowed the Clark identity to continue after the breakup and restructuring of the historical refining and retail enterprise. Clark-branded stations subsequently operated across 32 U.S. states, with more than 1,000 branded locations reported in the reference material. Some locations include convenience stores operating under the On the Go name. In 2013, Clark Brands acquired the brand-licensing business of Crown Central Petroleum, strengthening its position as a licensor and administrator of petroleum retail brands. The available reference material does not identify a current public listing, controlling owner, chief executive, or corporate website. Clark Brands is best understood today as a U.S. fuel-brand and licensing platform whose commercial footprint is delivered substantially through independent station operators.

History

Clark Brands developed from a fuel business founded by Emory T. Clark in 1932. The original operation was a single West Allis, Wisconsin, filling station trading as Clark Super Gas. It specialized in premium gasoline and did not provide the mechanical repair and tire-changing services commonly associated with many contemporary service stations. The business entered oil refining in 1943 and expanded rapidly during the following decade. By the mid-1950s, Clark operated nearly 500 stations across a broad group of Midwestern states, with additional locations in California and Florida. The company also pursued regional promotion through sponsorship of the Milwaukee Clarks minor-league ice hockey team from 1948 to 1950. During the 1970s, Clark Oil became a major independent refiner and marketer in the Midwest. Its network reached 1,489 stations and was supported by refineries in Blue Island and Hartford, Illinois. The company’s commercial model emphasized premium gasoline and high station throughput. The reference material states that an average Clark station sold roughly twice the national-average volume, helping the company achieve strong fuel margins. Ownership and corporate structure changed substantially in the 1980s. Emory T. Clark sold his interest to Apex Oil in 1981. Apex sought to sell Clark Oil in 1985, and both Clark and Apex were bankrupt by 1987. In 1992, a division of Horsham Corp. acquired Clark Oil and Refining, including the two refineries and approximately 1,000 stations. The company adopted the name Clark Refining and Marketing. Horsham later became TrizecHahn, after which 80 percent of Clark was sold to The Blackstone Group and another portion to Occidental Petroleum. The expanded refining business acquired a Lima, Ohio refinery from BP and a Port Arthur, Texas refinery from Chevron. The retail business was sold in 1999, and the remaining operation was renamed Premcor. The separation of the retail network continued to affect the Clark presence: many Clark stations in southeastern Michigan closed permanently in 2001. In 2003, Clark Brands, LLC was created to acquire the Clark trademark and related business assets from bankrupt Clark Retail. Rather than rebuild the historical vertically integrated oil company, the new organization concentrated on licensing the Clark identity to independent station operators. The licensing model enabled Clark-branded locations to continue operating across the United States. The reference material reports coverage in 32 states and more than 1,000 branded locations, with some sites combining fuel retailing and convenience stores under the On the Go name. In 2013, Clark Brands acquired Crown Central Petroleum’s brand-licensing business. This transaction further aligned Clark with a portfolio and platform role in petroleum retail branding rather than direct ownership of the full refining and station network. Current reference material does not provide a verified current executive roster, ownership structure, financial data, or official website.
