Supermarkets and Other Grocery Retailers (except Convenience Retailers)

U.S. industry primer — NAICS 2022 code 445110

A Histometrics industry primer for public- and private-market investors. Plain language, sourced.

1. Overview

This is the traditional grocery store business: fixed-location, full-line stores that sell a general line of food — fresh produce, meat, seafood, dairy, deli, bakery, frozen and canned goods, prepared meals, plus household staples. Think Kroger, Publix, H-E-B, Wegmans, Aldi, Trader Joe's, Whole Foods, and tens of thousands of independents. It is one of the largest and most familiar consumer industries in the country, generating roughly $809 billion in sales in 2022 across about 62,900 store locations and employing more than 2.8 million people.[1][2]

It is the textbook defensive industry: people eat in booms and recessions, so demand barely flexes with the economy. The catch is that it is brutally low-margin — a well-run chain often keeps just 1 to 2 cents of net profit per dollar of sales, sometimes less[5] — and intensely competitive. Operators make money on volume, operating discipline, and increasingly on higher-margin add-ons (store brands, pharmacy, fuel, retail-media advertising) rather than on markups. It is a business of pennies moved at enormous scale.

Public vs. private ways in. A handful of large operators trade publicly — Kroger, Albertsons, Ahold Delhaize, and several regional and specialty chains — so there is a real, liquid public-market universe here (Section 4). But some of the strongest names in American grocery are deliberately not public: Publix is employee-owned, H-E-B and Wegmans are family-owned, and Aldi, Lidl, and Trader Joe's are privately held by European owners. For private-market investors, the action is mostly in independent and regional chains, private-equity buyouts and growth capital, wholesale cooperatives, and the real estate under the stores rather than in the operating companies themselves.

2. What it is and how it's structured

What's in scope. NAICS (North American Industry Classification System) code 445110 covers establishments "generally known as supermarkets and other grocery retailers" that sell a general line of food. It includes conventional supermarkets, larger full-line grocery formats, delicatessen-type stores selling a general food line, and specialty, ethnic, natural, and organic grocers that carry a broad food assortment. Many of these stores also run pharmacies, fuel centers, bakeries, and prepared-food counters.[3]

What it explicitly excludes — this matters a lot. The code carves out several channels where Americans actually buy huge volumes of groceries:[3]

• Warehouse clubs and supercenters — Costco, Sam's Club, BJ's, Walmart Supercenter, and Target — sit in NAICS 455211 (Warehouse Clubs and Supercenters), not here.
• Convenience retailers (food marts without fuel) are NAICS 445131; convenience stores with fuel pumps are NAICS 457110 (Gasoline Stations with Convenience Stores); vending-machine operators are 445132.
• Single-line food stores — standalone produce (445230), meat (445240), fish and seafood (445250), bakeries (445291), confectionery/nut shops (445292), and other specialty food retailers (445299).
• Beer, wine, and liquor stores (445310), limited-service restaurants (722513), and local grocery-delivery services (492210).

The practical consequence: the federal figures for 445110 undercount how Americans really shop for food. Walmart is the single largest U.S. grocery seller by a wide margin, and Costco ranks among the top handful — yet neither is counted in this industry because their formats are classified as supercenters and warehouse clubs.[6] So read the $809 billion below as the size of the traditional supermarket / standalone-grocery channel, not total U.S. grocery spending, which is materially larger once clubs, supercenters, and convenience stores are added in. A related point for equity investors: a listed grocer may report its grocery sales inside a broader corporate segment, so public-company results never map cleanly onto the NAICS totals.

Ownership mix. The industry is a barbell. At one end sit a few very large chains (national and multi-regional). At the other sit tens of thousands of small independents and single-store operators — of roughly 41,600 firms running the ~62,900 establishments, most are small. The U.S. Small Business Administration (SBA) size standard for the industry is $40 million in average annual receipts, below which a grocer counts as "small" for federal-contracting purposes (this is a contracting threshold, not an industry revenue benchmark).[1][4] Ownership structures are unusually varied: publicly traded corporations, diversified public parents with grocery subsidiaries, employee-owned companies (Publix, WinCo, Hy-Vee), family dynasties (H-E-B, Wegmans, Meijer), European private owners (Aldi, Lidl, Trader Joe's), and member-owned wholesale cooperatives (Wakefern/ShopRite, Associated Wholesale Grocers) that supply independent banner stores. The federal statistics do not provide a public-versus-private ownership split.

3. How big it is

Our ground-truth federal statistics for NAICS 445110:

Undercount caveat. These are employer-based counts: County Business Patterns covers establishments with paid employees, and the Economic Census concentration tables cover firms with payroll.[1][2] They therefore exclude tiny nonemployer operators, and — more importantly — they exclude the supercenter and warehouse-club channel by design (Section 2). So the $809 billion here is smaller than the "grocery industry" as consumers experience it; it captures the supermarket channel cleanly but leaves out the biggest single grocery seller in the country. Our source file contains no nonemployer total, so we make no adjustment for it.

Concentration. At the national level the industry looks unconcentrated. The four largest firms took 39.2% of receipts (CR4), the top 8 took 52.9% (CR8), the top 20 took 65.7%, and the top 50 took 74.6%; the Herfindahl-Hirschman Index (HHI, a standard concentration measure that runs to 10,000) was just 506.7.[1] For context, the 2023 federal Merger Guidelines treat a market above 1,800 as highly concentrated — this industry sits far below that nationally.[22]

That national number is misleading, and the tension is central to the industry's biggest recent event. Grocery is bought and sold locally — you shop the stores near your home — so what matters for competition is the handful of chains in a given metro, not the national tally. USDA research finds that food-retail concentration rises sharply as the geographic market narrows: a market can look fragmented nationally while one or two chains dominate locally.[21] That gap is exactly why the Federal Trade Commission (FTC) was able to block the Kroger-Albertsons merger in 2024 (Section 8) even though the combined company would still have trailed Walmart nationally.[7]

4. The investable universe

There is a genuine public-market universe here, but it is topped by a few names and shadowed by very large private owners. Tickers below are for identification, not recommendations.

Publicly traded operators (primarily 445110-type supermarkets):

Adjacent diversified parents (grocery-heavy, but classified outside 445110): Walmart (NYSE: WMT) and Costco (Nasdaq: COST) are the largest grocery sellers in the country, but their supercenter and warehouse-club formats sit in NAICS 455211. Amazon (Nasdaq: AMZN) owns Whole Foods Market and Amazon Fresh; Whole Foods is a supermarket-format chain technically inside this industry, but it is a small slice of a giant diversified parent. These are ways to own grocery exposure, but each buries it inside a much larger, differently-classified business.

Major private / other owners (not directly investable):

• Publix Super Markets — the largest U.S. employee-owned company; ~$59.7B 2024 sales, ~1,390 stores.[6][13] Shares trade only internally to employees.
• H-E-B — Texas powerhouse controlled by the Butt family, with employee ownership through a partner-stock plan; among the largest private companies in the U.S.[6][13]
• Aldi (US) — privately held by Germany's Aldi Süd; ~$29B 2024 sales and the fastest physical expansion in the industry. It acquired Southeastern Grocers (Winn-Dixie, Harveys) in 2024 and continues an aggressive store-growth push.[6][14]
• Trader Joe's — owned by Germany's Aldi Nord; private, no IPO.[13]
• Lidl (US) — privately held German discounter, expanding on the East Coast.
• Wegmans, Meijer — family-owned; WinCo Foods, Hy-Vee — employee-owned.[13]
• C&S Wholesale Grocers — private wholesaler-retailer running company-operated stores (Grand Union, Piggly Wiggly, and others); says it completed its acquisition of SpartanNash in 2025.[13][20]
• Giant Eagle — historically family-owned; Kroger announced an agreement to acquire it in 2026, subject to closing.[19]

Takeaway for investors: you can own the supermarket channel through KR, ACI, ADRNY/AD, and the specialty and regional names, but you cannot directly buy the two disruptive forces reshaping it — Walmart's grocery machine (inside a much larger, differently-classified retail parent) and privately held Aldi/Lidl/Trader Joe's. Several of the best-loved American grocers are closed to outside equity.

5. How the money works

Grocery is a thin-margin, high-turnover business. The economics are the opposite of a luxury brand: you make very little per item and survive by selling enormous quantities efficiently and turning inventory fast before it spoils. Store revenue is driven by customer traffic, transaction frequency, average basket size, price changes, new stores, and digital orders.

The margin stack. Gross margin (sales minus the cost of the goods) typically runs about 20-27% of sales; almost all of it is eaten by labor, rent, utilities, refrigeration, distribution, payment processing, and shrink (spoilage and theft), leaving a net profit margin usually in the low single digits — roughly 1-3%, and sometimes less.[5] Recent filings show the squeeze: Albertsons reported a ~27% gross margin but only ~0.3% net margin in its latest fiscal year, while Kroger reported a ~23% gross margin.[8][9] (Company definitions differ — fuel, pharmacy mix, and accounting conventions all move these figures — so treat them as examples, not a universal average.) Because the margin is so thin, small operational edges — a fraction of a point of shrink, a better labor schedule, a tighter supply chain — decide who wins.

The metrics owners and analysts actually watch:

• Same-store (identical / comparable) sales — the growth of stores open at least a year, stripping out new openings. This is the health gauge, and it matters most when you can separate real traffic and volume from mere price inflation. Kroger's identical sales without fuel rose about 1.8% in fiscal 2024; a specialty grower like Sprouts posted double-digit total growth.[8][11] Company definitions of "identical" vary, so cross-company comparisons require care.
• Unit economics: sales per store, sales per square foot, and inventory turns. Food turns many times a year; the faster the turn, the less capital is tied up and the less spoils.
• Private-label (store-brand) penetration. Store brands carry higher margins than national brands and now make up roughly a fifth to a quarter of sales at strong chains.[5] Growing the store-brand mix is one of the few levers that lifts margin without raising shelf prices — a core strategy at Aldi, Trader Joe's, Costco (Kirkland), and Kroger (Our Brands) — though it demands strong sourcing, quality control, and brand management.
• Retail media / advertising income. Chains increasingly sell ad placement and shopper data to brands (e.g., Kroger Precision Marketing). This income is nearly pure profit and is quietly becoming a meaningful earnings driver on top of razor-thin store margins.
• Loyalty and personalization. Loyalty programs turn purchase data into targeted promotions, bigger baskets, and the retail-media inventory above.
• Ancillary profit pools: in-store pharmacies, fuel centers, and financial services often earn more per dollar than the grocery aisles and drive trips.

Cash and capital. Grocers collect cash at checkout but pay suppliers on terms, so a healthy chain funds a chunk of its inventory with supplier credit (favorable working capital) — but fresh product can become worthless fast if forecasts or execution fail. Free cash flow funds store remodels, e-commerce/automation build-out, dividends, and buybacks. Real estate is a distinct value layer: owning versus leasing store sites is a major balance-sheet and strategic choice, and sale-leaseback of grocery-anchored real estate is its own investment niche.

---

6. What drives demand

Food is a recurring necessity, but shoppers readily switch stores, formats, brands, package sizes, and channels — so demand is stable in aggregate yet fiercely contestable at the store level.

• Population and food-at-home spending. Baseline demand tracks the number of households and how much of the food budget is spent eating at home versus at restaurants. The long-run shift toward dining out is a structural headwind; events that push people back to home cooking (recessions, inflation spikes, the pandemic) are tailwinds.
• Food price inflation. Grocery revenue is unusually sensitive to food inflation because much of "growth" is really price, not volume. Food-at-home prices rose about 2.7% year over year through June 2026.[25] Rising prices flatter same-store sales but also push shoppers to trade down (to discounters and store brands) and shrink basket sizes — the pattern discounters like Aldi, Lidl, and Grocery Outlet exploit.
• Government nutrition benefits. The Supplemental Nutrition Assistance Program (SNAP, formerly food stamps) is a large, direct demand source: it served about 41.7 million people a month and paid out roughly $99.8 billion in fiscal 2024, most of it redeemed at supermarkets and superstores. The Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) is another meaningful grocery channel. Changes to SNAP funding or eligibility move real grocery volume, so the program is a genuine macro variable for the industry.[15]
• Convenience and channel shift. Online grocery is now structural: roughly one-fifth of grocery spending flows through digital channels (delivery, store pickup, ship-to-home), and a majority of U.S. households have bought groceries online at least occasionally.[16] Winning the digital trip — via owned apps and third parties like Instacart — increasingly determines share, even though fulfillment economics are hard (Section 9).
• Value-seeking behavior. Discount and hard-discount formats (Aldi, Lidl, Grocery Outlet, warehouse clubs, dollar stores) keep taking share, especially when budgets tighten. Simultaneously, premium/natural formats (Whole Foods, Sprouts, Trader Joe's) grow the other end. The conventional middle is squeezed from both sides.

---

7. Regulation

Grocery is lightly regulated as a business but heavily regulated on food and labor:

• Food safety. The FDA (Food and Drug Administration) publishes the Food Code, a model that state, local, tribal, and federal authorities adopt; day-to-day retail food oversight is generally handled at the state and local levels.[23] The FDA's Food Safety Modernization Act (FSMA) framework touches supplier records, traceability, and preventive controls. The USDA (U.S. Department of Agriculture) Food Safety and Inspection Service (FSIS) regulates meat, poultry, and egg products, with specific rules and exemptions for retail operations.[24]
• SNAP / EBT and WIC. Stores must be authorized by USDA's Food and Nutrition Service to accept SNAP, must meet staple-food stocking requirements, and must operate EBT (Electronic Benefit Transfer) equipment; WIC authorization is handled by state agencies. New rules taking effect November 2026 tighten stocking requirements (a wider variety of foods, including perishables) for the roughly 250,000 SNAP-authorized retailers.[15]
• Labor. A large share of supermarket workers — especially at Kroger and Albertsons — are unionized under the UFCW (United Food and Commercial Workers). Contract cycles drive periodic strikes and strike threats; in early 2025, King Soopers (Kroger) workers in Colorado struck, and contracts covering well over 100,000 workers came up for renewal across several states.[17] State minimum-wage increases and scheduling laws also weigh on the industry's biggest cost line.
• Antitrust. Because grocery competition is local, the FTC, the Department of Justice (DOJ), and state attorneys general scrutinize mergers closely and can block deals on local-market grounds even when the national picture looks unconcentrated (Section 8).[7][22]
• Other rules. State/local alcohol and pharmacy licensing; weights-and-measures and unit-pricing rules; consumer-privacy, payment-security, and cybersecurity requirements; and product-recall, labeling, allergen, refrigeration, and environmental rules round out a patchwork of state and local obligations.

8. Competitive dynamics and consolidation

The defining fact of modern U.S. grocery is that the biggest competitors are not traditional supermarkets. Walmart alone holds roughly 21% of U.S. grocery sales, with Costco near 8-9%, versus about 9% for Kroger and 5% for Albertsons.[19] Conventional supermarkets are squeezed from three directions at once: mass/club (Walmart, Costco), hard discount (Aldi, Lidl, dollar stores), and e-commerce/premium (Amazon/Whole Foods, Trader Joe's, Sprouts). Scale is the counterweight — it improves purchasing power, distribution efficiency, private-label economics, loyalty data, advertising, and technology — and local density matters as much as national size, because nearby stores share distribution and marketing costs and make pickup and delivery efficient.

That competitive pressure drove the industry's landmark event. In 2022 Kroger agreed to buy Albertsons for about $24.6 billion — the largest supermarket merger ever proposed — arguing the two needed scale to compete with Walmart, Costco, and Amazon. The FTC sued to block it, and in December 2024 a federal court in Oregon granted a preliminary injunction (a Washington state court blocked it separately). The judge rejected the "we need to be big to fight Walmart" defense, finding the deal would reduce competition and weaken union bargaining power in local markets. Kroger and Albertsons abandoned the merger the next day, and follow-on litigation between the two companies ensued.[7][18]

Consolidation continues, but at a regional scale and under heavy scrutiny rather than through another national blockbuster:

• ALDI acquired Southeastern Grocers (Winn-Dixie, Harveys) in 2024.[14]
• C&S Wholesale Grocers says it completed its acquisition of SpartanNash in 2025.[20]
• Kroger announced an agreement to acquire Giant Eagle in 2026, subject to closing.[19]

The broader strategic response is now organic and technological: private-label expansion, aggressive discounter store growth (Aldi's continued build-out), automated fulfillment and retail-media build-out, and continued shakeout among sub-scale independents that lack the capital for e-commerce and automation. Expect continued regional consolidation and asset swaps rather than another national mega-merger in the near term.

9. Risks

• Margin compression. With net margins in the low single digits,[5] there is almost no cushion. Wage inflation, minimum-wage hikes, a bad shrink year, or a price war can wipe out profit.
• Competitive share loss. Walmart's low prices, Costco's value, dollar stores, and Aldi/Lidl's hard-discount expansion continuously pull share from conventional supermarkets.[19]
• Labor. Unionized workforces mean strike risk and rising labor costs; grocery is labor-intensive and can't easily automate the store floor.[17]
• Food deflation as well as inflation. Inflation flatters sales; when food prices cool, reported same-store sales can go flat or negative even if unit volumes hold, pressuring the earnings story of public names.
• E-commerce economics. Online grocery (delivery especially) is expensive to fulfill and often dilutive to already-thin margins; building it is necessary but not obviously profitable.[16]
• Operational hazards. Spoilage, shrink, theft, out-of-stocks, recalls, food-safety incidents, refrigeration and energy costs, cyberattacks, and overbuilt or badly-sited stores all bite directly into thin margins.
• Policy risk. SNAP is a large demand input; benefit cuts or program disruptions directly reduce grocery volume, disproportionately at stores serving lower-income areas.[15]
• Antitrust and private-company opacity. Blocked or delayed acquisitions constrain the growth-by-scale playbook; and for private targets, limited disclosure and leverage make underwriting harder for outside investors.
• Concentration in the format, not the code. Investors buying "grocery" via public supermarket stocks are buying the channel most exposed to the Walmart/club/discount threat, since several winners of the last decade are private or classified elsewhere.

10. How to invest and the outlook

Public routes. The cleanest large-cap exposures are Kroger (KR) and Albertsons (ACI); Ahold Delhaize (AD / ADRNY) offers U.S. grocery exposure inside a European-listed parent. For growth tilts, Sprouts (SFM) and Grocery Outlet (GO) play the natural/organic and extreme-value niches; Weis (WMK), Ingles (IMKTA), Village Super Market (VLGEA), and Natural Grocers (NGVC) are small regional/specialty operators. Walmart (WMT), Costco (COST), and Amazon (AMZN) are indirect, heavily diluted routes with grocery buried inside larger businesses. Direct operators give purer exposure but are more sensitive to execution, labor, pricing, and local competition; diversified parents offer stronger balance sheets but obscure grocery performance. These names are typically owned for defensive stability and income (dividends/buybacks) rather than rapid growth; valuation multiples are modest, reflecting thin margins and slow top-line growth. Broad consumer-staples ETFs also carry grocery weightings.

Private routes. Because several of the strongest operators are closed (Publix employee-only, H-E-B/Wegmans/Meijer family, Aldi/Lidl/Trader Joe's foreign-private), private-market participation usually comes through: (a) control buyouts or growth capital in independent and regional chains; (b) grocery-anchored real estate — the shopping centers and standalone boxes under the stores, a favored net-lease category prized for recession-resilient, e-commerce-resistant tenants; and (c) suppliers, wholesalers (co-ops like Wakefern, Associated Wholesale Grocers; distributors like C&S), cold-chain logistics, grocery software, delivery infrastructure, and private-label manufacturers selling into the channel. Underwriting should focus on store-level cash generation, lease-adjusted leverage, working capital, labor stability, and defensible local market share rather than national footprint.

A practical diligence checklist:

• Are same-store sales growing on traffic and volume, or only on price?
• Are gross margins stable after labor, shrink, and delivery costs?
• Are new stores earning acceptable returns without cannibalizing existing locations?
• Is private-label growth improving both value to shoppers and profitability?
• Are inventory, leases, debt, and capital spending manageable?
• Is there a defensible local position, or merely a large national footprint?
• Could any proposed acquisition survive local antitrust review?

Near-term drivers to watch (forward-looking): the pace of food-price inflation (which sets reported sales growth); the trajectory of SNAP funding and the November 2026 stocking rules; UFCW contract outcomes and strike activity across Kroger/Albertsons markets; Aldi and Lidl's store expansion and its share impact on conventional chains; the profitability (not just growth) of online grocery; and how aggressively incumbents convert data into high-margin retail-media income. With the Kroger-Albertsons mega-merger dead, expect the competitive battle to be fought store-by-store on price, private label, and digital — a slow-growth, defensively attractive, but structurally pressured industry where operational excellence and differentiation, not consolidation, now separate winners from losers.
