Gasoline Stations (U.S.) — NAICS 4571: An Investor's Primer

NAICS (North American Industry Classification System) is the U.S. government's standard code for grouping businesses. This page covers the four-digit industry group 4571, "Gasoline Stations," which folds together the two five-digit industries beneath it: 45711 — Gasoline Stations with Convenience Stores and 45712 — Other Gasoline Stations. The real value of reading one level up is the contrast between those two children — they are the same broad business (selling motor fuel) but have almost mirror-image economics, ownership, and direction of travel. Section 2 leads with that comparison; the rest covers the group as a whole. For leaf-level detail, follow through to the child primers.

1. Overview

NAICS 4571 is the entire American gas-station industry as the federal government defines it: roughly $722 billion in annual receipts across about 64,783 firms [1]. It is one of the largest, most visible, and most fragmented slices of U.S. consumer retail — a near-ubiquitous format that most Americans use weekly and that most investors already own indirectly, whether they know it or not.

But "gas station" is not one business. The group splits cleanly into two very different formats:

• The corner c-store (45711) — a pump out front and a convenience store (c-store) behind the register selling coffee, snacks, drinks, tobacco, and increasingly hot prepared food. This is where three-quarters of the group's revenue sits and where the profit actually lives (in the store, not the pump). It is highly fragmented and slowly consolidating.
• The pump-only site (45712) — gasoline and diesel with no attached store. This end is dominated by a handful of giant warehouse-club and big-box fuel islands (Costco, Sam's Club, Kroger, BJ's) at the top and a thinning tail of small independents at the bottom. It is a shrinking, unusually concentrated format.

The single most useful thing to understand about this level is that its two halves are moving in opposite directions and are owned by opposite kinds of investor. That divergence — not the group average — is the story.

2. What's inside — the two child industries and how they differ

NAICS is a nested hierarchy: the four-digit group 4571 contains two five-digit industries, each with a single six-digit national industry of the same name and scope. The two children are the same trade seen from opposite ends.

CR4 is the combined revenue share of the four largest firms; HHI (Herfindahl-Hirschman Index) sums every firm's squared market share into one score — below 1,500 is "unconcentrated" by U.S. antitrust convention. MLP and REIT are defined in Section 4.

Read the table this way. Both codes sell fuel, yet almost everything else about them is opposite. 45711 is the big, fragmented, consolidating half where the store is the profit engine and where you can buy publicly listed pure-play operators. 45712 is the smaller, concentrated, shrinking half where a few giant retailers use cheap gasoline to pull members and grocery shoppers, and where no pure-play public company exists — exposure comes wrapped inside something bigger. The most important dynamic between them is one-directional: a pump-only independent that bolts on a store literally reclassifies out of 45712 and into 45711, which is one reason 45712's tail keeps thinning while 45711 holds the volume.

For boundary lines — what sits in the neighboring codes (no-fuel c-stores in 445131; fuel dealers who deliver heating oil and propane in 457210) — see Section 2 of either child primer.

3. Size — the group's rollup figures

Because 4571 is a true aggregate of two children, its federal figures are the sum of theirs. Our ground-truth file for this four-digit level holds the U.S. Census Bureau's 2022 Economic Census concentration data:

Two reads. First, this is enormous — over $720 billion of receipts, comparable to the largest consumer-retail categories in the country. Second, at the national level it is statistically unconcentrated: a CR4 of 26.7% and an HHI of 231 sit far below the 1,500 threshold regulators treat as even "moderately concentrated" [1]. The group HHI (231) is modestly higher than the c-store child's (196) precisely because it now blends in the top-heavy pump-only child — but the average still says "no one dominates nationally." As always in fuel retail, individual local markets can be far more concentrated than the national picture suggests.

Note on adding up the children. The children's receipts ($533.8B + $187.8B) sum almost exactly to the group's $721.7B. The firm counts, however, do not simply add: 56,502 + 8,986 = 65,488, which is slightly above the group's 64,783. That is expected — a company operating both formats is counted once at the group level but can appear in each child, so the parent count is the deduplicated total, not the sum [1][2][3].

Undercount / scope caveats.

• Employer-only coverage. These Economic Census figures cover employer businesses (firms with paid staff and an Employer Identification Number). They exclude self-employed and no-employee operators [1]. Small and individual ownership is genuinely understated here — single-store "mom-and-pop" sites dominate the c-store child (roughly six in ten stores are single-site) [5], and the pump-only child has a real tail of owner-only, unmanned card-lock, and marina sites with no payroll [3]. Treat the firm and site counts as a floor; we assert no all-operator total and state no suppressed value.
• One concentration figure is suppressed. The pump-only child's HHI is withheld in the federal data and is not stated here [3]. The group HHI (231) is published and is used above.
• Employment lives at the child level. Our file for this group does not carry establishment, employee, or payroll counts. Those employer-census figures are reported one level down and, summed, give roughly 109,000 establishments and about 1.02 million paid employees (2023) across the group — about 96,002 establishments / 848,306 employees in the c-store child and ~13,172 / ~168,654 in the pump-only child [4].
• A broader trade measure counts something different. The industry association NACS (National Association of Convenience Stores) tallies the whole convenience channel — about 151,975 U.S. stores and $817.5 billion in total sales (roughly $476.3B fuel + $341.2B in-store) [5]. That is the channel on a trade basis; the federal $721.7 billion is the narrower, cleaner employer slice. Both are correct — they count different universes.

4. Investable universe — where value concentrates across the children

The two children are reached through completely different routes, so map them separately.

Inside 45711 (the c-store half) — this is where the listed pure-plays are:

• Public pure plays: Casey's General Stores (CASY) and Murphy USA (MUSA) are the cleanest U.S.-listed operators; ARKO Corp. (ARKO) is a smaller, more leveraged operator-plus-wholesaler.
• Global c-store owners (foreign-listed): Alimentation Couche-Tard (ATD / ANCTF), owner of Circle K, and Seven & i Holdings (SVNDY), parent of 7-Eleven.
• Private champions: family- and employee-owned chains such as Wawa, Sheetz, QuikTrip, Kwik Trip, and Buc-ee's, plus private-equity roll-ups and single-site independents.

Inside 45712 (the pump-only half) — no pure play exists; exposure is wrapped or private:

• Diversified public retailers where pump-only fuel is one segment — Costco (~747 fuel stations), Walmart/Sam's Club, Kroger (~1,731 fuel centers), BJ's [9]. The fuel is a traffic magnet for memberships and grocery baskets, so its economics never surface as a standalone "gas station" line.
• Private operators and the wholesale/jobber layer that supplies the stations — the only direct pump-only exposure.

Shared across both children (the layers underneath the store):

• Fuel-distribution master limited partnerships (MLPs — pass-through entities that pay out most cash as distributions): Sunoco (SUN), Global Partners (GLP), CrossAmerica Partners (CAPL), World Kinect (WKC).
• Station real estate via a net-lease REIT (real estate investment trust — a company that owns income property and passes rent to shareholders): Getty Realty (GTY), which owns the land under stations regardless of who pumps the fuel.

The takeaway on where value concentrates: the publicly investable pure exposure is overwhelmingly in the c-store child (45711). The pump-only child (45712) holds a quarter of the group's revenue but is essentially uninvestable on a pure-play basis — you buy it as a slice of Costco or Kroger, as a wholesale distributor, or privately. Tickers, gallon volumes, and per-company scale are in Section 4 of each child primer [10][11].

5. How the money works

One rule governs the whole group: fuel is most of the revenue but little of the profit. Gasoline is a high-ticket, mostly pass-through product — most of the pump price is the fuel itself plus tax, not the retailer's take — which is why the group posts $722 billion of receipts from only ~64,783 firms. Fuel margin is measured in cents per gallon (CPG), not percentage: gross margins have run about 35–40 CPG lately, and after credit-card interchange (~2.5% per swipe) and other costs, net is often only ~15 CPG [6].

Where the two children diverge is what carries the thin fuel margin:

• In 45711, the store carries it — high-margin foodservice (prepared food, coffee, fountain drinks) is the real profit engine, and fuel becomes upside rather than the crutch that supports the site.
• In 45712, there is no store, so the pump is subsidized by something outside the site — a Costco membership, a Kroger grocery basket — which is exactly why the standalone pump-only independent, with nothing to cross-subsidize, is the most exposed format.

The largest shared cost is the underground storage tank (UST): leak detection, replacement, and cleanup liability that can, in a bad case, exceed the value of the land. Full unit economics and the metrics owners watch are in Section 5 of each child primer.

6. Demand drivers

The demand backdrop is the same for both children and it is quietly negative for the fuel half: U.S. vehicle-miles traveled hit a record in 2024, yet gasoline consumption is falling — about 8.9 million barrels per day in 2025, roughly 4% below the 2019 level — as new vehicles get more efficient and electric plus hybrid vehicles reached about 22% of light-duty sales in 2025 [7]. Peak U.S. gasoline is behind us (2018 was the high-water mark), so the whole group competes for share of a slowly shrinking fuel pie [7].

The offsetting growth vector sits almost entirely in the c-store child: the shift of "food-away-from-home" spending toward c-store kitchens, plus immediacy, location, and loyalty data. Cheaper pump prices also leave more cash to spend inside the store. Declining tobacco/nicotine volumes and the gradual rise of EV charging affect both. See Section 6 of each child primer.

7. Regulation

Fuel retail is one of the more heavily regulated small-business trades in America, and the rules apply almost identically across both children. The central one is the underground storage tank: the U.S. Environmental Protection Agency (EPA) requires leak detection, spill/overfill protection, and proof of financial responsibility (40 CFR Part 280), enforced mostly by states [8]. Layered on top: Clean Air Act fuel rules (vapor recovery, seasonal Reid Vapor Pressure limits, "boutique" blends), the federal Renewable Fuel Standard for biofuel blending, the Petroleum Marketing Practices Act (PMPA) protecting fuel-franchise dealers, tobacco/vapor/alcohol licensing and age verification (weighted toward the c-store child), and federal-plus-state fuel taxes collected at the pump (18.4 CPG federal on gasoline, unchanged since 1993) [8].

The competitive effect is the same in both halves: a tank replacement or contamination event is a large, site-specific expense a well-capitalized operator absorbs and a marginal one cannot — quietly favoring scaled owners and pushing the industry toward consolidation. Full detail in Section 7 of each child primer.

8. Consolidation

The through-line for the whole group is fragmentation slowly giving way to scale, but it looks different in each child:

• In 45711, large chains buy cheaper fuel, run private-label and foodservice programs a single store cannot match, and enjoy cheaper capital — so they out-earn and then buy the independents. The signal event of 2025 was Couche-Tard's withdrawal of its ~$47 billion bid for Seven & i (7-Eleven), which kept the global top two separate and left the U.S. field open for American growth chains.
• In 45712, price-leader clubs and big-box grocers are the growth engine, the oil majors have gone asset-light (licensing brands, leaving operations to dealers and wholesalers), and the classic pump-only independent is being closed, sold, or converted into a c-store — which reclassifies it into 45711. UST cleanup is often the gating cost of any sale or redevelopment.

Because competition is fundamentally local, deals in either child routinely trigger site-level antitrust remedies. The gap between the group's ~64,783 firms and ~109,000 establishments confirms the barbell of multi-site chains sitting over many single-location owners [1][4]. See Section 8 of each child primer.

9. Risks

• Secular fuel-demand decline — the shared, defining risk: improving fuel economy and EV growth slowly erode the gasoline half of both children [7]. It is real but gradual, and it bites the pump-only child (45712) hardest because it has no store to fall back on.
• Thin, volatile margins — ~15 CPG net leaves little cushion, and fuel margins swing with wholesale-price moves ("rockets and feathers") [6].
• Environmental tail risk — a UST leak can create liability larger than a site's value [8].
• Format disadvantage — the pure pump-only independent has no c-store cross-subsidy; the poorly located gas-only site loses relevance first.
• Capital intensity and leverage — remodels, tank compliance, and roll-up debt all press on marginal operators.
• Reporting opacity — public issuers blend retail, wholesale, real estate, and international lines, and in 45712 the fuel is buried inside a much larger retailer, so the industry's true economics rarely surface in any single "gas station" company [3].

10. How to invest & outlook

Routes, by child. The publicly investable pure exposure is in the c-store half (45711): direct operators (CASY, MUSA, ARKO), foreign-listed globals (ATD/ANCTF, SVNDY), and — shared with the pump-only half — the fuel-distribution MLPs (SUN, GLP, CAPL, WKC) and the net-lease landlord (GTY). Normalize earnings for an unusually high or low fuel-margin year before judging any operator; there is no simple U.S.-listed pure c-store index fund, so exposure is stock-by-stock. The pump-only half (45712) offers no pure public play — you own it as a segment of Costco, Walmart, Kroger, or BJ's, or you go private. Private investors in either child underwrite the store, the site, and the fuel/branding contract separately — buying a single site or small portfolio, backing a PE roll-up, or purchasing the net-lease real estate under an operating store for long, bond-like rent — with tank age and environmental records as make-or-break diligence.

Outlook (judgment). The fuel engine common to both children faces a slow, decades-long structural decline as vehicles electrify — so top-line fuel growth is not the thesis anywhere in this group. Durable value sits in the c-store child, where a foodservice-led, consolidating store defended by real estate and compliance barriers keeps taking share. The pump-only child is the more exposed half: its high-volume price leaders (clubs, big-box grocers) will endure, but its low-volume independents get closed, converted into c-stores, or redeveloped. Expect the group's center of gravity to keep tilting toward 45711 — operators with dense locations, strong prepared food, loyalty data, EV-charging optionality, and manageable environmental exposure win, while gas-only and poorly located sites fade. Full tickers, valuation lenses, and diligence checklists are in Section 10 of each child primer.
