In at least two local communities across Indiana, Ohio, and Pennsylvania, Circle K’s parent company attempted to buy the only other gas station competitor in town — which would have left drivers with exactly one choice for fuel and zero leverage to push back on price hikes.

The Deal They Tried to Pull Off

On August 16, 2024, Alimentation Couche-Tard Inc. — the Canadian corporation that owns Circle K — signed a Unit Purchase Agreement through its subsidiary Mac’s Convenience Stores LLC. The target: all 270 retail fuel outlets owned by Giant Eagle, Inc. and its affiliated entities, including GetGo Operating, LLC and Riser Foods Company.

Giant Eagle is based in Cranberry Township, Pennsylvania. Its GetGo-branded fuel stations are a fixture in working-class communities across three states. ACT planned to absorb every one of them, wiping Giant Eagle out of the fuel market entirely.

The Federal Trade Commission filed its complaint against both companies on June 25, 2025, charging that the acquisition would violate Section 7 of the Clayton Act and Section 5 of the FTC Act — the core federal laws designed to stop corporations from crushing competition.

Who Is Alimentation Couche-Tard?

ACT is incorporated in Canada and headquartered in Laval, Quebec. It operates Circle K Stores Inc. as a wholly owned subsidiary out of San Antonio, Texas. Circle K is already one of the largest convenience store and gas station chains in North America. This acquisition was an attempt to grow even larger by eliminating a direct rival in concentrated local markets.

Giant Eagle built its GetGo fuel network alongside its grocery stores, giving price-sensitive families a competitive alternative at the pump. That alternative is what ACT wanted to eliminate.

How Gas Prices Are Really Set: They Watch Each Other

Most people assume gas prices are set by some distant oil market and that local stations are just passing those costs along. The FTC’s complaint tears that illusion apart. ACT and Giant Eagle stations actively monitor each other’s prices and change their own prices in response — constantly, in real time.

The FTC calls this competitive pricing discipline. When two rivals are watching each other, neither can easily jack up prices without losing customers to the other. Take that second player off the board, and the remaining one can raise prices with no fear of losing a single driver to a competitor that no longer exists.

The complaint notes that competition between fuel outlets “may be very local, often including fuel outlets in close geographic proximity and on specific traffic patterns.” That means the station on your specific commute route is your real competitor — and Circle K was trying to buy that competitor too.

Gas Is Not Optional — And That’s the Point

The FTC is explicit: “There are no substitutes for gasoline for gasoline-powered vehicles. Consumers can purchase gasoline only at retail fuel outlets.” The same goes for diesel. You cannot choose a different product. You cannot shop online. You cannot delay a fill-up indefinitely. This is a captive market, and Circle K wanted to own it.

Working-class families, tradespeople, delivery workers, and rural commuters — people who drive out of necessity, not luxury — are exactly the consumers who feel every cent of a price hike at the pump. A Canadian corporation headquartered in Quebec was attempting to consolidate that captive demand in dozens of American communities into a single brand with zero competition to answer to.

The Monopoly Math: Market by Market Breakdown

The FTC identified 35 local markets across Indiana, Ohio, and Pennsylvania where the acquisition would harm competition. These are real neighborhoods, real intersections, real commutes. The numbers are stark.

For diesel, the destruction runs parallel: 6 markets dropping from 5 to 4 competitors, 8 markets from 4 to 3, 3 markets from 3 to 2, and 2 markets dropping to a single diesel seller.

What “Highly Concentrated” Actually Means for Your Wallet

The FTC uses the Herfindahl-Hirschman Index (HHI) to measure how monopolized a market is. Under the 2023 Merger Guidelines, any market scoring above 1,800 is classified as highly concentrated. A single deal that pushes that score up by more than 100 points is presumed — by law — to substantially harm competition.

Every single one of the 35 affected markets would have hit that threshold after this deal closed. In the two markets where competition would have collapsed to a single seller, there is no HHI calculation needed. The index maxes out at 10,000. That is the definition of a monopoly.

The Non-Financial Ledger: What a Gas Price Hike Actually Costs People

There is a version of this story told in spreadsheets and merger filings. Then there is the version lived by the person working a double shift at a distribution center in suburban Ohio, pulling out of the lot at 11 p.m. with a quarter tank and exactly one gas station on the way home. That station is a GetGo. The station across the street is a Circle K. Right now, those two signs force each other to keep prices honest. Under this deal, one of them disappears — and the person on the night shift has no leverage left.

Fuel poverty is real and it is rarely discussed by the people making acquisition decisions in Laval, Quebec. When gas prices rise even 10 to 15 cents per gallon in a local market with no competition, the impact compounds across every fill-up for every household in that ZIP code. A family with two working adults, each driving 30 miles round-trip to their jobs, filling up twice a week, feels every fraction of a cent Circle K decides to add once the competition is gone. There is no app that saves you. There is no competitor to drive to. The road goes where it goes, and the station on that road is the station you use.

Tradespeople and small business operators who run diesel-powered vehicles face an even sharper squeeze. The FTC identified 19 local diesel markets where this acquisition would have either reduced sellers to one or two, with no realistic new entrants on the horizon. A plumber running a diesel pickup, a farmer fueling equipment, a small trucking operation — these are not abstractions. Every extra dollar per gallon pulled out of their operating costs is a dollar that does not go toward hiring, toward wages, toward keeping their own prices affordable for the customers they serve.

The FTC’s complaint makes a quiet but devastating observation: in these markets, ACT and Giant Eagle stations are “frequently located along the same traffic routes and are geographically proximate to each other, making them a clear (and sometimes the only) alternative for consumers.” Read that again. In some of these communities, Circle K and GetGo are the entire competitive landscape. Remove one, and there is nothing. The document is careful and legal in its language. What it describes, plainly, is a corporation attempting to eliminate the only check on its own greed in neighborhoods where people have no other option.

Legal Receipts: The FTC’s Own Words

“There are no substitutes for gasoline for gasoline-powered vehicles. Consumers can purchase gasoline only at retail fuel outlets. There are no substitutes for diesel fuel for diesel-powered vehicles. Consumers can purchase diesel only at retail fuel outlets. No economic or practical alternative exists to the retail sale of gasoline or diesel fuel at retail fuel outlets.” FTC Complaint, paragraph 14 — The Market Definition Section

“Respondents’ stations routinely monitor each other’s prices and use that information when setting their own prices for gas and diesel fuels. The Respondents’ stations are frequently located along the same traffic routes and are geographically proximate to each other, making them a clear (and sometimes the only) alternative for consumers.” FTC Complaint, paragraph 21 — Effects of the Acquisition

“There are few third-party stations in these locations that could provide an effective competitive constraint on ACT post-acquisition or serve as a reasonable alternative for consumers in the event that ACT chose to increase prices by a small but significant and non-transitory amount.” FTC Complaint, paragraph 21 — On the absence of alternatives

“Entry into each relevant market will not be timely, likely, or sufficient to deter or counteract the anticompetitive effects arising from the Acquisition. Significant entry barriers include the availability of attractive real estate, the time and cost associated with constructing a new retail fuel outlet, and the time associated with obtaining necessary environmental and other permits and approvals.” FTC Complaint, paragraph 20 — Barriers to Entry

“The Acquisition, if consummated, would violate Section 7 of the Clayton Act, as amended, 15 U.S.C. § 18, and Section 5 of the FTC Act, as amended, 15 U.S.C. § 45.” FTC Complaint, paragraph 23 — The Formal Charge

Societal Impact Mapping

Economic Inequality: The Price of a Captive Market

The FTC’s complaint centers on 35 local markets across Indiana, Ohio, and Pennsylvania — states that are home to large working-class populations, significant rural communities, and economies built around manufacturing, logistics, and agriculture. These are exactly the communities where fuel costs hit hardest, because residents drive longer distances, earn lower median wages, and have fewer alternatives to gas-powered transportation than urban centers.

The FTC’s own language makes the inequality dimension explicit: competition in these markets is “very local, often including fuel outlets in close geographic proximity and on specific traffic patterns.” That means price discipline only works because of the specific station on the specific road you drive every day. When Circle K acquires that other station, it does not just remove a competitor in the abstract. It removes the one price anchor that prevents the station you depend on from charging whatever it wants.

The complaint confirms that ACT and Giant Eagle stations are “close or closest competitors” in these markets. The loss of that competition increases the probability of both unilateral price increases — one company raising prices because it can — and coordinated price increases, where remaining competitors implicitly agree to stop undercutting each other. Either outcome transfers money directly from working families to a Canadian corporation’s balance sheet, one fill-up at a time.

The barriers to entry section of the complaint closes the door on any hope of a new competitor emerging to fix the problem. Real estate availability, construction costs, permitting delays, and environmental approval timelines all function as a moat around the gas station industry. Once Circle K wins a local market, it wins it for years. There is no cavalry coming. The FTC’s intervention is the only mechanism standing between communities and long-term price exploitation.

Public Health: Diesel, Dependency, and Who Gets Left Behind

Diesel fuel is the lifeblood of working supply chains and agricultural operations. Farmers fueling tractors and combines, independent truckers running regional routes, construction operators keeping job sites running — all of these workers depend on diesel availability and competitive pricing to keep their operations viable. The FTC identified 19 diesel market scenarios across the three states where this acquisition would have either created monopoly conditions or reduced sellers to two, with no meaningful new entry possible.

When diesel costs rise without competitive constraint, the burden does not stay with the companies buying the fuel. It gets passed down. Small operators raise their prices. Logistics costs climb. Food costs more. Construction gets more expensive. The cost of Circle K’s market power radiates outward through every supply chain that depends on affordable diesel, ultimately landing on the same working families already paying more at the pump for gasoline.

The health dimension is indirect but real. Families squeezed by higher fuel costs cut elsewhere. They delay vehicle maintenance. They drive older, less fuel-efficient vehicles longer. They make longer, more stressful commutes to find cheaper gas when none exists. Financial stress compounds. These are not hypothetical outcomes; they are the documented downstream effects of fuel market consolidation in communities with limited transportation alternatives.

The Cost of Consolidation: By the Numbers

What Now: Who to Watch and What to Do

The Corporate Actors

• Alimentation Couche-Tard Inc. — Canadian parent corporation headquartered in Laval, Quebec. Filed the acquisition agreement on August 16, 2024.
• Circle K Stores Inc. — ACT’s wholly owned U.S. subsidiary, based in San Antonio, Texas. The operational face of the deal.
• Mac’s Convenience Stores LLC — The ACT subsidiary that signed the Unit Purchase Agreement and would have taken legal ownership of the 270 stations.
• Giant Eagle, Inc. — The seller. Based in Cranberry Township, Pennsylvania. Also named as a respondent in the FTC complaint for agreeing to the deal.

The Watchlist: Regulatory Bodies with Authority Here

• Federal Trade Commission (FTC) — filed the complaint; has authority to block the merger outright
• Department of Justice Antitrust Division (DOJ) — concurrent jurisdiction over merger enforcement
• State Attorneys General (Indiana, Ohio, Pennsylvania) — can pursue independent state antitrust actions
• Consumer Financial Protection Bureau (CFPB) — relevant if pricing practices produce predatory consumer harm

What You Can Actually Do

The FTC accepted public comments on this merger. For the next case — and there will be a next case — filing a public comment with the FTC costs nothing and takes ten minutes. It creates a paper trail. It signals political will. Combine that with contacting your state Attorney General’s consumer protection office, supporting local mutual aid networks that help neighbors with transportation costs, and organizing with worker and tenant groups already fighting monopoly pricing in housing, healthcare, and food. The same corporations consolidating gas stations are consolidating everything else. The resistance to one is the resistance to all.
