Circle K

• 1. Introduction

  ›

  Circle K sells 17 Polar Pop fountain drinks every second in the United States, a figure the company reported as of 2018. Those cups pass through a convenience store chain that, by February 2020, had more than 14,800 stores carrying its name around the world. The chain belongs to Alimentation Couche-Tard, a multinational operator based in Laval, Quebec, which since 2003 has bought rival chains and repainted them under a single name. A company with that reach might be expected to have grown in a straight line. It did not. Who started it, and where did the name come from? Why did a chain that once sat near the top of its industry lose ground? What did a Canadian buyer see in it? And what happens to a neighborhood store when the sign above it changes?

  ›

  In 1951, an entrepreneur named Fred Hervey bought three Kay's Food Stores in El Paso, Texas, from their owner, Kay Misenheimer. Rather than keep the Kay's name, Hervey renamed the shops Circle K Food Stores, Inc. He pushed the chain into neighboring New Mexico and Arizona, and Arizona has been the company's home base since 1957. Hervey later served two terms as mayor of El Paso.

  By 1975, the chain counted 1,000 stores across the United States. In 1979 it went abroad for the first time, through a licensing agreement that opened the first Circle K stores in Japan under a partner called UNY. The Japanese operator was later called Circle K Japan Company until 2004 and Circle K Sunkus Company until 2016, when it became the FamilyMart Company. It licensed the brand from Couche-Tard until 2018, when every Circle K in Japan was converted to FamilyMart.

  The year 1983 added scale at a stroke. Circle K bought UtoteM, a chain of 960 stores in the western and southern United States, which lifted its total to 2,180. Karl Eller, a prominent Phoenix businessman, became CEO that year and held the job until 1990.

  Under Eller, annual sales climbed from $747 million to more than $3 billion. Circle K became the second largest convenience store operation in the country and the largest publicly owned chain, with 4,631 stores in 32 states. Another 1,300 or so licensed or joint venture stores operated in 13 foreign countries. One of those licensees began in 1985, when Li & Fung Retailing took the Circle K name to Hong Kong.

  ›

  In 1988, Circle K sent a letter to its more than 8,000 employees about medical coverage. The company would stop covering anyone who fell sick or was hurt because of AIDS, alcohol, drug abuse or self-inflicted wounds. It defended the rule with these words: "There are certain lifestyle decisions that we are just not going to assure the results of."

  The late 1980s brought a slowing American economy, and the chain's fortunes sank with it. In May 1990, Circle K filed for Chapter 11 bankruptcy protection, and Eller resigned as CEO. Some underperforming locations were sold or closed.

  Investcorp, an international investment group, bought the company in 1993, and Circle K emerged from bankruptcy. Tosco Corporation, an independent petroleum refiner and marketer, acquired it in 1996 but kept the headquarters in Phoenix. Phillips Petroleum bought Tosco in 2001. In 2002, Phillips merged with Conoco to form ConocoPhillips.

  Then, in 2003, Alimentation Couche-Tard, a large convenience store operator based in the Montreal area, bought Circle K for US$830 million. Not every partner stayed through the change. In 2005, Taiwan's OK Convenience Store chain terminated its franchise agreement with Circle K.

• 4. Couche-Tard Builds Out

  ›

  In 2005, Couche-Tard folded its own Mac's, Bigfoot, Dairy Mart and Handy Andy stores under the more nationally known Circle K name. The following year it bought Spectrum, a 90-store chain serving Georgia and Alabama, along with the CFM chain in Missouri. It also took on 35 Sterling Dairy locations in Northwest Ohio and 26 stores under various brands from Chico Enterprises of Morgantown, West Virginia.

  Mid-2006 brought a different kind of deal. Couche-Tard signed a franchising agreement with ConocoPhillips to brand some of that company's own stores in the western United States as Circle K. ConocoPhillips remodeled the stores into the Circle K scheme but kept running them, with its unified canopy design and ProClean fuels. The stores were spun off as Phillips 66 in May 2012, and Phillips 66 fuel is among the brands sold at Circle K stores today.

  In July 2008, Canada-based Irving Oil leased its Bluecanoe and Mainway convenience stores, in the United States and Atlantic Canada, to Couche-Tard. Couche-Tard rebranded them as Circle K while the stores kept selling Irving-branded fuel. The Mainway stores in Newfoundland and Labrador did not change until summer 2010. The deal brought the Circle K name to Canada, while an earlier, similar partnership in Quebec had produced stores operating as Couche-Tard.

  In April 2009, ExxonMobil sold 43 Phoenix stores to Couche-Tard as part of the sale of its larger On the Run franchise. By July 2010, Circle K had fallen to fourth place by store count, with 3,455. 7-Eleven led with 6,523, followed by BP with 4,730 and Shell with 4,630.

  In April 2012, Circle K paid $2.8 billion for Norway-based Statoil Fuel and Retail ASA. The purchase brought 2300 fuel stations in Scandinavia, the Baltics, Poland and western Russia. On the 10th of February 2014, Modelo Group sold its Tiendas Extra stores to Circulo K, the Mexican franchise of Circle K.

  On the 18th of December 2014, Couche-Tard announced an all-cash tender offer of $860 million for The Pantry. Many Pantry stores operated as Kangaroo Express, and all were expected to carry the Circle K banner after the deal closed in March 2015.

• 5. One Brand Worldwide

  ›

  On the 12th of August 2015, Circle K opened its first five stores in Costa Rica, after buying and rebranding a local chain called Delimart. Six weeks later, on the 23rd of September 2015, Couche-Tard unveiled a refreshed Circle K identity. It announced that Circle K would become the worldwide brand for its stores, replacing names such as Mac's, Kangaroo Express and Statoil. Two exceptions were kept: the Couche-Tard name in Quebec and the INGO brand in Europe.

  The new logo drew on elements of the brands it replaced. The plan also promised better products, better technology and store improvements aimed at the customer experience. The change ran over five years. By March 2020, all of Europe and 85% of North America carried the Circle K brand and logo, and more than 800 Mac's stores in central and western Canada had been converted by 2019.

  As of February 2020, Circle K had 9,799 stores in North America and 2,697 in Europe. A further 2,380 operated under franchise agreements worldwide. In the United States it owns and operates stores in 48 states; only Nebraska and Utah have none. Louisiana has the largest concentration.

  With 7,230 American stores, Circle K ranked second to 7-Eleven's 9,348 as of July 2019. Since the 1980s it has been the largest chain of company-owned, non-franchised convenience stores in the country.

  Fuel at Circle K stores is sold under many brands, and the Circle K and Shell names are the most common. Others include Valero, BP, Exxon, Marathon, Irving, Mobil and Esso. About 13% of stores worldwide sell no fuel at all.

  Company-run stores operate in the United States, Canada, Hong Kong and Europe, including the Nordics, the Baltics, Poland, Russia and Ireland. Franchises exist in Mexico, where the partner stores called Tiendas Extra were created by Modelo Group. Others are in Cambodia, China, Egypt, Guam, Honduras, Indonesia, Jamaica, Macau, New Zealand, Saudi Arabia, South Africa, the United Arab Emirates and Vietnam.

  In Hong Kong and Macau, the stores are called OK, a reference to the circle around the K. Fung Retailing, the licensee formerly known as Li & Fung Retailing, sold the business back to Couche-Tard in 2020. Hong Kong had 387 franchised locations as of May 2020.

• 6. Deals Since 2016

  ›

  In 2016, Couche-Tard acquired Topaz, an Irish service station chain, and in April 2018 it announced that Topaz would become Circle K too. It similarly acquired Imperial Oil's Esso retail locations, 228 in Ontario and 50 in Quebec. The Ontario convenience stores, many of which had operated as On the Run, were rebranded as Circle K.

  In 2017, Couche-Tard completed its acquisition of CST Brands. That deal added stores formerly owned by Valero Energy, plus part of the Ultramar chain in Canada. The Ultramar stores also switched fuel suppliers to Irving.

  Holiday Stationstores, a Minnesota-based chain of fuel stations in the Midwestern United States, was also bought in 2017. Couche-Tard planned to bring Holiday's food service model, full-service franchise program and car wash subscriptions into Circle K. Some locations piloted store formats patterned after Holiday's.

  In November 2018, Circle K opened its first store in New Zealand through a master franchisee, Pamma Retail Group. In September 2021, it announced the purchase of 10 convenience and food stores from the Griffin Group in Ireland. All were in busy parts of Dublin, such as O'Connell Street, College Green, Grafton Street and Sandyford.

  In February 2022, Couche-Tard said it would rebrand 12 Holiday Stationstores locations in Sioux Falls, South Dakota, as Circle K. In April 2022, The Wall Street Journal reported that Couche-Tard was considering a bid for EG Group, a British convenience store and restaurant operator. That purchase would have enlarged its presence in Australia, Western Europe, the United Kingdom and the United States, especially in Florida, New England and Ohio. EG Group instead arranged a sale and leaseback of its American stores. Most of its British gas stations and restaurants went to the retailer Asda in 2023.

  On the 19th of August 2024, Couche-Tard announced it would buy Pittsburgh-based GetGo from Giant Eagle. The deal greatly expanded Circle K in Pennsylvania, where all its existing stores descend from Lawson's and Dairy Mart. It also complemented stores in Ohio, Indiana, West Virginia and Maryland.

  The Federal Trade Commission signed off on the 26th of June 2025. To satisfy antitrust concerns, Georgia-based Majors Management bought 34 Circle K stores and one GetGo location and rebranded them as MAPCO. All but two of those divestitures were in the Indianapolis and Akron, Ohio markets. The deal closed on the 29th of June 2025.

  GetGo remains headquartered at Giant Eagle's base in Cranberry Township, Pennsylvania, in separate leased space. That is a different location from Circle K's headquarters in Tempe or its Great Lakes offices in Akron, which sit in the former Lawson's and Dairy Mart headquarters. The GetGo name is expected to continue, at least in the short term, even as Couche-Tard keeps rebranding Holiday Stationstores as Circle K.

• 7. Polar Pops and Sponsors

  ›

  Circle K's fountain drinks are poured into Polar Pop cups, which were previously called Thirst Busters. Most are expanded polystyrene, though plastic or paper cups are offered where polystyrene is illegal, and the 52-ounce cups are plastic. At most American locations, any size of 32 ounces or under costs less than $1, while cups of 52 ounces and above cost more. The 44-ounce size, marketed as "Epic XL" in some regions, may fall on either side of a dollar depending on the region.

  The Polar Pop first appeared in Bigfoot convenience stores, run by Johnson Oil Company in Columbus, Indiana, before Couche-Tard acquired that business in 2003. Circle K filed a trademark for Polar Pop in 2005. In 2007, it reached a settlement agreement with Polar Beverages over the use of the name.

  The Froster arrived in Mac's stores in 1998 and became very popular throughout Western Canada and Ontario. An American version followed in 1999.

  Lawson's branded chip dip is carried in Circle K's Great Lakes division, which covers Indiana, Kentucky, Michigan, Ohio, Pennsylvania and West Virginia. It came over from the former Lawson's and Dairy Mart stores and then spread to other acquired stores in the division. After the GetGo purchase, GetGo stores began carrying it too. The locations divested to MAPCO had to stop, because the dip is a private label product of Circle K.

  From 2011 to 2013, Circle K was a part-time primary sponsor of the No. 28 IndyCar Series car driven by Ryan Hunter-Reay of Andretti Autosport. In 2014, it switched to KVSH Racing driver Sébastien Bourdais. It now sponsors Marco Andretti, together with Oberto Sausage Company.

  In 2017, Circle K went to NASCAR, sponsoring Matt Kenseth and Joe Gibbs Racing with full livery for six races. Its car was on the track when Kenseth won his final Cup race, at that year's fall event at Phoenix Raceway. That year it also became the official shirt sponsor of North Carolina FC in the United Soccer League. It signed a two-year sponsorship agreement with the Lithuanian Basketball League, and in May 2017 a Circle K Power Cube was introduced into the online game Ingress.

  Because of its large presence in Greater Cleveland, inherited from the Lawson and Dairy Mart stores, Circle K sponsors the Cleveland Guardians strikeout sign. The sign hangs in center field at Progressive Field. Its "K" logo stands for the K used for strikeouts in traditional baseball scorekeeping and is replicated with each strikeout.

  The same sponsorship exists with the Arizona Diamondbacks at Chase Field in Phoenix. If the Diamondbacks strike out ten batters or more, everyone at the game receives a voucher for a free cup of Polar Pop. Guardians fans receive the same voucher after select home games. In 2025, Circle K became the official convenience store sponsor of Minor League Baseball, with signage and activations at most ballparks in the United States.

• 8. Complaints and Commitments

  ›

  A 2021 report on wage theft by the Center for Public Integrity named Circle K as one of the "worst offenders" in the United States. A class-action lawsuit had been brought against the company in 2014, and in 2019 it agreed to pay a settlement of US$8.3 million. Circle K settled a similar class-action lawsuit in 2015.

  In 2018, Couche-Tard committed to stop sourcing battery cage eggs for its corporate-owned Circle K stores in North America and Europe by 2025. In 2023, the company expanded the goal to cover international franchise locations. In March 2025, the animal protection organization The Humane League criticized Circle K for failing to publicly report progress toward the commitment. The pledge's 2025 deadline makes those missing progress reports the detail to watch.
