Gasoline Stations and Fuel Dealers (U.S. NAICS 457) — An Investor's Primer

The North American Industry Classification System (NAICS) is the U.S. government's standard code for grouping businesses. This page covers the three-digit subsector 457, "Gasoline Stations and Fuel Dealers," which rolls up the two four-digit industry groups beneath it: 4571 — Gasoline Stations and 4572 — Fuel Dealers. The real value of reading one level up is the contrast between those two children — they are both "selling refined fuel to the end user," but one pumps it into a car at a roadside site and the other trucks it into a tank at a home or farm, and almost everything else about them — size, customer, economics, ownership, and how you invest — differs. Section 2 leads with that comparison; the rest covers the subsector as a whole. For leaf-level detail, follow through to the child primers.[4][5]

1. Overview

NAICS 457 is the last mile of the U.S. fuel business — the point where refined petroleum products finally reach the person who burns them. The 2022 edition of NAICS groups two long-separate retail trades under one three-digit roof: the roadside gasoline station and the truck-based fuel dealer. Together they are roughly $765 billion in annual receipts across about 68,576 firms [1] — one of the larger, more visible, and more fragmented slices of U.S. consumer retail.

But this is not one business. The subsector splits into two very different ways fuel gets to a customer:

• Gasoline Stations (4571) — the near-ubiquitous roadside format: a pump out front, usually with a convenience store (c-store) behind the register selling coffee, snacks, drinks, and hot food. Customers are motorists who pull in and pay at the pump. This is ~94% of the subsector's revenue [1][2].
• Fuel Dealers (4572) — the delivered-fuel business: propane (also called liquefied petroleum gas, or LPG), home heating oil, and smaller volumes of kerosene and diesel, hauled by tank truck and pumped into a customer's tank. Customers are homes, farms, and small businesses in rural and older-suburban areas that natural-gas pipelines never reached. This is the remaining ~6% [1][3].

The single most useful thing to understand about this level is that its two halves serve different customers, run on different economics, decline for different reasons, and are owned by different kinds of investor. That divergence — not the subsector average — is the story.

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

NAICS is a nested hierarchy: the three-digit subsector 457 contains two four-digit industry groups. They are both "retail fuel," seen from opposite ends of the delivery chain.

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 children sell refined fuel to end users, and both are genuinely fragmented small-business trades — but they barely overlap otherwise. 4571 is the giant, visible, motorist-facing half where the convenience store — not the pump — is the profit engine, where fuel demand is in slow secular decline, and where you can buy publicly listed pure-play operators. 4572 is the small, out-of-sight, home-heating half where volume rises and falls with how cold the winter is, where the dealer often owns the tank in the customer's yard (so customers rarely switch), and where the only liquid public exposure is a short list of high-yield partnerships. One is ~17 times the size of the other; one is a consumer-convenience story, the other a weather-driven income-and-consolidation story.

For boundary lines — no-fuel c-stores, warehouse-club fuel islands, the petroleum wholesalers who supply dealers (NAICS 4247), and pipeline natural-gas utilities (in the Utilities sector) — see Section 2 of either child primer.[4][5]

3. Size — the subsector's rollup figures

Because 457 is a true aggregate of two children, its federal figures are essentially the sum of theirs. Our ground-truth file for this three-digit level holds the U.S. Census Bureau's 2022 Economic Census concentration data:

Two reads. First, this is enormous — roughly $765 billion of receipts, comparable to the largest single categories in U.S. consumer retail. Second, at the national level it is statistically unconcentrated: a CR4 of 25.2% and an HHI of 206 sit far below the 1,500 line regulators treat as even "moderately concentrated" [1]. The subsector HHI (206) lands between the two children's (231 for gasoline stations, 133 for fuel dealers), pulled toward the gasoline-station figure because that child is ~94% of the whole [1][2][3]. The average says "no one dominates nationally" — but as always in fuel, individual local markets can be far more concentrated than the country-wide picture suggests.

Note on adding up the children. The children's receipts (~$721.7B + ~$43.3B) sum almost exactly to the subsector's ~$765.0B [1][2][3]. The firm counts nearly add too (64,783 + 3,984 = 68,767 vs. the subsector's 68,576); the small gap is expected — a company operating in both groups is counted once at the subsector level but can appear in each child, so the parent count is the deduplicated total, not a clean sum [1].

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 in both children — single-store "mom-and-pop" sites dominate the gasoline-station child (roughly six in ten stations are single-site) [6], and fuel dealing is a locally owned, family-run trade [5]. Treat the firm counts as a floor; we assert no all-operator total and state no suppressed value.
• Nothing is suppressed at this level. Every figure above is published in our ground-truth file. (One child figure — the pump-only sub-industry's HHI — is withheld in the federal data and is not stated in the 4571 primer; it does not affect the subsector totals here.) [4]
• Receipts are a commodity-price snapshot. 2022 was a high-energy-price year. Because both children pass wholesale fuel costs straight through to customers, reported dollar receipts swing widely year to year even when gallons barely move. Read the dollar figure as volatile, not as a clean measure of "size" [4][5].
• Employment lives at the child level. Our file for this subsector does not carry establishment, employee, or payroll counts. Those employer-census figures are reported one level down and, summed, give roughly 117,000 establishments and about 1.1 million paid employees across the subsector — about 109,000 establishments / ~1.02 million employees in the gasoline-station child and ~7,700 / ~72,000 in the fuel-dealer child [7].
• A broader trade measure counts something different. The industry association NACS (National Association of Convenience Stores) tallies the whole convenience channel at about 151,975 U.S. stores and $817.5 billion in total sales (roughly $476.3B fuel + $341.2B in-store) [6]. That is the channel on a trade basis and overlaps mostly with the gasoline-station child; the federal ~$765 billion is the narrower, cleaner employer slice of both children. 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. Tickers and figures appear only in this section and Section 10.

Inside 4571 (Gasoline Stations) — this is where the listed pure-plays are. Value there concentrates in the c-store half:

• 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 (PE) roll-ups and single-site independents.
• Pump-only, wrapped inside something bigger: warehouse clubs and big-box grocers — Costco, Sam's Club, Kroger, BJ's — run large fuel operations as a traffic magnet, so there is no pure public play for that slice.
• The layers underneath the store: fuel-distribution master limited partnerships (MLPs — pass-through entities that pay out most of their cash as distributions): Sunoco (SUN), Global Partners (GLP), CrossAmerica Partners (CAPL), World Kinect (WKC); and 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).

Inside 4572 (Fuel Dealers) — no large pure-play stock exists; the real ownership is private:

• The most liquid public exposure: UGI Corporation (UGI), owner of AmeriGas, the largest U.S. retail propane marketer — but diversified across regulated gas utilities and midstream.
• High-yield partnerships: Suburban Propane Partners (SPH) and Ferrellgas Partners (FGPR, which also runs the Blue Rhino cylinder-exchange brand) in propane; Star Group (SGU), the largest publicly traded home-heating-oil dealer; and Canada-listed Superior Plus (SPB).
• Private owners hold the bulk: family dealers (ThompsonGas, Blossman Gas, Dead River Company, HOP Energy), farm/energy cooperatives (CHS, GROWMARK/FS, MFA Oil), and PE roll-up platforms.

The takeaway on where value concentrates: the publicly investable pure exposure lives overwhelmingly in the two children's operating names — listed c-store operators in 4571 and the propane/heating-oil MLPs in 4572 — but they sit at opposite ends of the risk-and-yield spectrum. 4571's pure-plays are growth-and-consolidation equities; 4572's are high-current-yield income vehicles. Full tickers, gallon volumes, and per-company scale are in Section 4 of each child primer.[4][5]

5. How the money works

One rule governs the whole subsector: the fuel commodity is most of the revenue but little of the profit. Both children largely pass wholesale fuel costs through to customers, so headline receipts swell and shrink with oil prices while the operator's real economics — the spread and the adjacent services — stay comparatively stable. That is why ~$765 billion of receipts comes from only ~68,576 firms.

Where the two children diverge is what actually earns the margin:

• In 4571, fuel margin is measured in cents per gallon (CPG), not percentage — gross margins have run about 35–40 CPG lately, netting only ~15 CPG after credit-card interchange and costs [8]. The thin pump margin is carried by the store: high-margin foodservice (prepared food, coffee, fountain drinks) is the profit engine, and fuel becomes upside rather than the whole business.
• In 4572, owners make money on gallons delivered × margin per gallon, plus service revenue — heating, ventilation, and air-conditioning (HVAC) work, tank rental, and appliance sales. The spread counter-intuitively often widens when wholesale prices fall (retail prices lag), and tank ownership (the dealer owns the tank in the customer's yard) makes switching a hassle, so retention is high. The key levers are volume (driven by winter cold), route density (cost per gallon falls as customers cluster), and service revenue that smooths a winter-heavy year.

Because revenue can rise simply because fuel prices rose, in both children the numbers that matter are volume, margin, and cash flow — not headline receipts. Full unit economics are in Section 5 of each child primer.[4][5]

6. Demand drivers

The two children run on almost opposite demand clocks.

• 4571 is driven by driving — and that engine is slowly fading. 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 2019) as vehicles get more efficient and electric-plus-hybrid models reached about 22% of light-duty sales in 2025 [9]. Peak U.S. gasoline is behind us (2018 was the high-water mark) [9]. The offsetting growth vector sits almost entirely in the c-store: the shift of "food-away-from-home" spending toward c-store kitchens, plus immediacy, location, and loyalty data.
• 4572 is driven by weather. The dominant year-to-year swing factor is winter cold (measured in heating degree days); the U.S. Energy Information Administration's (EIA) Winter Fuels Outlook is the industry's key demand signal [10]. Underneath the weather noise, the residential core is in slow secular decline — natural-gas expansion, electric heat pumps, and population drift toward the warmer South and West — partly offset by non-heating gallons (crop drying, forklift/autogas, standby generators, and record U.S. propane exports).

The common thread: both children ultimately sell a fuel whose end-use is being electrified — gasoline by electric vehicles, home heat by heat pumps and gas mains — so neither child's core volume is a growth story. See Section 6 of each child primer.[4][5]

7. Regulation

Both children are lightly economically regulated — no utility rate base, no franchise monopoly — but heavily safety- and environmentally regulated, just in different places along the chain.

• 4571's central rule is the underground storage tank (UST). 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 [11]. Layered on: Clean Air Act fuel rules (vapor recovery, seasonal blends), the Renewable Fuel Standard, the Petroleum Marketing Practices Act protecting fuel-franchise dealers, tobacco/alcohol licensing, and fuel taxes collected at the pump (18.4 CPG federal on gasoline, unchanged since 1993) [11].
• 4572's central rules govern moving and storing a combustible fuel. Cargo tank trucks and cylinders fall under the Pipeline and Hazardous Materials Safety Administration (PHMSA) and Department of Transportation (DOT) hazmat rules; storage and installation follow the National Fire Protection Association's NFPA 58 (Liquefied Petroleum Gas Code) and state LP-gas boards; the EPA applies spill-prevention and risk-management thresholds [5].

The competitive effect is the same in both: a large, site-specific compliance or contamination event (a tank replacement, a cleanup, a truck incident) is an expense a well-capitalized operator absorbs and a marginal one cannot — quietly favoring scale and pushing both children toward consolidation. A shared forward wildcard is decarbonization policy — state and municipal moves to restrict fossil-fuel use in new construction, and the broader electrification agenda. Full detail is in Section 7 of each child primer.[4][5]

8. Consolidation

The through-line for the whole subsector is fragmentation slowly giving way to scale, and the mechanism rhymes across both children even though the players differ.

• In 4571, large chains buy cheaper fuel, run foodservice and private-label 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. UST cleanup is often the gating cost of any site sale or redevelopment.
• In 4572, national marketers, farm cooperatives, and — increasingly — PE roll-ups are buying up independents, driven by a wave of retiring owners without succession plans and PE capital seeking stable cash flow. Deals price on EBITDA multiples (earnings before interest, taxes, depreciation, and amortization) or on a per-gallon/per-customer basis, with the acquired tank base and route density the prize.

Because competition is fundamentally local in both, deals routinely turn on site-level or market-level effects rather than national share. The gap between the subsector's ~68,576 firms and ~117,000 establishments confirms a barbell of multi-site owners sitting over a long tail of single-location operators [1][7]. See Section 8 of each child primer.[4][5]

9. Risks

• Secular fuel-demand decline — the shared, defining risk. Improving efficiency and electric vehicles erode gasoline (4571); electrification, heat pumps, and gas-main expansion erode home-heating fuels (4572) [9][10]. It is real but gradual, and it bites the parts with nothing to fall back on hardest — the gas-only site without a store, and the residential-only dealer.
• Thin, pass-through margins. ~15 CPG net in gasoline leaves little cushion [8], and both children's dollar revenues (and working-capital needs) swing with wholesale prices even when volume is flat [4][5].
• Weather risk (4572-specific). A warm winter can cut a dealer's volume sharply in a single season [10].
• Environmental and safety tail risk. A UST leak (4571) can create liability larger than a site's value [11]; propane and heating oil are combustible and carry hazmat exposure (4572) [5].
• Capital intensity and leverage. Remodels and tank compliance (4571), truck/plant/tank assets (4572), and roll-up debt across both all press on marginal operators.
• Reporting opacity. Public issuers blend retail, wholesale, real estate, utility, and international lines; in the pump-only slice fuel is buried inside a much larger retailer, and in fuel dealing the public MLPs bundle propane with other energy businesses — so the pure economics rarely surface in any single "gas station" or "fuel dealer" company [3][5].

10. How to invest & outlook

Routes, by child.

• The gasoline-station child (4571) is a stock-by-stock equity story: listed c-store operators (CASY, MUSA, ARKO), foreign-listed globals (ATD/ANCTF, SVNDY), and the shared underlying layers — fuel-distribution MLPs (SUN, GLP, CAPL, WKC) and a 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. The pump-only slice offers no pure public play — you own it as a segment of Costco, Kroger, Walmart, or BJ's, or privately.
• The fuel-dealer child (4572) is an income-and-consolidation story: high-yield MLPs (SPH, SGU, FGPR) for cash yield — accepting K-1 tax forms (the partnership tax statement), seasonal earnings, and thin trading — or UGI for the most liquid, 1099-simple but diversified exposure. There is no large, liquid pure-play.
• Private investors in either child buy or build a local operator (typically low-to-mid single-digit EBITDA multiples, with the site or tank base as collateral), back a PE roll-up, or — in 4572 — provide private credit or join a farm/energy cooperative. In 4571, environmental and tank records are make-or-break diligence; in 4572, the tank base and route density are the prize.

Outlook (judgment). The fuel commodity common to both children faces a slow, decades-long structural decline as vehicles and home heat electrify — so top-line fuel-volume growth is not the thesis anywhere in this subsector. Durable value comes from what sits beside the fuel: in 4571, a foodservice-led, consolidating convenience store defended by real estate and compliance barriers; in 4572, sticky, tank-anchored customer relationships, service revenue, and roll-up economics in a fragmented field of retiring owners. Expect both children to keep consolidating toward scaled operators with dense locations (4571) or dense routes (4572), while gas-only sites and residential-only dealers fade. The subsector's revenue will stay dominated by gasoline stations, but its most defensible profits increasingly come from the store and the service relationship, not the gallon. Full tickers, valuation lenses, and diligence checklists are in Section 10 of each child primer.[4][5]
