Automobile and Light Duty Motor Vehicle Manufacturing (U.S.) — NAICS 336110
A Histometrics industry primer for public-market and private investors.
1. Overview
NAICS 336110 covers the companies that assemble finished cars and light trucks in the United States — the final-assembly plants that turn thousands of parts into a complete passenger car, pickup, minivan, or sport-utility vehicle (SUV). NAICS (the North American Industry Classification System) is the standard the U.S. government uses to group businesses. This is the visible tip of a much larger auto economy: the assemblers themselves are a small, concentrated set of very large factories, sitting on top of a vast parts, dealer, and finance ecosystem that federal data classifies separately.
Why an investor cares: vehicle manufacturing is one of the largest, most cyclical, and most politically exposed industries in the country. It employs skilled, largely unionized labor at roughly double the average private-sector wage, it is a bellwether for consumer health and interest rates, and it is in the middle of an expensive, uncertain transition to electric vehicles (EVs) alongside a sharp swing in trade and emissions policy. Fortunes here move on unit volumes, pricing discipline, and factory utilization — not on any single quarter's headline.
Ways in. Public-market investors get direct exposure through a handful of large listed automakers (General Motors, Ford, Tesla, Stellantis) and speculative EV startups (Rivian, Lucid), plus U.S.-listed foreign makers via American Depositary Receipts (ADRs — foreign shares that trade on U.S. exchanges). Private investors rarely buy an assembler outright — building cars is too capital-intensive — and instead reach the industry through parts suppliers, dealer groups, battery and charging ventures, and venture or private-equity stakes in the (mostly money-losing) EV and autonomy startups.
2. What it is and how it's structured
Scope. NAICS 336110 comprises establishments that make complete automobiles and light-duty motor vehicles — bodies on a chassis, or unibody vehicles — or that make the light-vehicle chassis alone. Included vehicle types are passenger cars, light-duty trucks, light-duty vans, pickups, minivans, and SUVs, and this explicitly includes battery-electric automobiles.[1] Today's single code consolidated two once-separate codes: 336111 (Automobile Manufacturing, i.e. passenger cars) and 336112 (Light Truck and Utility Vehicle Manufacturing) — a change that means historical six-digit series cannot be joined mechanically.[1]
What it excludes (named adjacent NAICS codes, so you can see the boundaries):
- 336120 — Heavy Duty Truck Manufacturing (Class 7–8 trucks: semis and large commercial rigs).
- 336211 — Motor Vehicle Body Manufacturing and 336213 — Motor Home Manufacturing (building bodies or motor homes on purchased chassis).[1]
- 3363 — Motor Vehicle Parts Manufacturing (engines, transmissions, seating, brakes, steering, electrical, batteries) — a far larger employer than assembly itself.
- 336999 — race cars; 441110 — New Car Dealers (retail selling and service); vehicle rental and repair are elsewhere again.
So this code is just the assemblers. When you read the federal figures below, remember they measure final-assembly plants only — not the parts makers, dealers, or lenders that make the auto industry a ~3–3.5% slice of U.S. gross domestic product (GDP).[2]
Operating model. The practical operating unit is the assembly plant, although the economic decision-maker is usually a global OEM. Manufacturers design platforms and powertrains, engineer and certify vehicles, source components through tiered supplier networks, stamp and weld bodies, paint, perform final assembly and testing, and then distribute vehicles through franchised dealers or, for Tesla and some newer entrants, direct-sales systems. Plants are organized around high throughput and model-specific tooling; product programs commit engineering, tooling, launch, and certification expenditure long before sales begin, creating substantial fixed cost and operating leverage. The supply chain is tightly synchronized: GM describes its production system as just-in-time and says it normally carries minimal inventories — improving working capital but making semiconductor shortages, logistics failures, supplier insolvencies, strikes, and border disruptions capable of stopping an entire assembly line.[3]
Ownership mix. Two overlapping groups run these plants. First, the "Detroit Three" domestic makers — General Motors, Ford, and Stellantis (the Chrysler/Jeep/Ram/Dodge business). Second, foreign-headquartered "transplants" — Toyota, Honda, Hyundai-Kia, Nissan, Subaru, Volkswagen, BMW, and Mercedes-Benz — that operate large U.S. assembly plants, concentrated in Alabama, Tennessee, South Carolina, Kentucky, Georgia, Texas, Ohio, and Indiana.[4] Because these transplant plants are U.S. establishments, they are counted inside the federal 336110 statistics even though the parent companies trade abroad. Tesla and a few EV startups (Rivian, Lucid) round out the domestic-owned set.
3. How big it is
Federal statistics for NAICS 336110 (assembly plants only):
| Metric | Value | Source (year) |
|---|---|---|
| Receipts (shipments) | $357.2 billion | Economic Census, 2022[5] |
| Firms | 170 | Economic Census, 2022[5] |
| Establishments (plants) | 222 | County Business Patterns, 2023[6] |
| Paid employees | 236,806 | County Business Patterns, 2023[6] |
| Annual payroll | $28.0 billion | County Business Patterns, 2023[6] |
| Avg. pay per employee (derived) | ~$118,000 | derived from payroll ÷ employment[6] |
| SBA small-business threshold | 1,500 employees | SBA size standards, 2023[7] |
A few things stand out. This is a concentrated, capital-intensive industry: about 170 firms and roughly 222 plants generate over $357 billion in shipments — an average of more than $1.5 million of output per worker.[5][6] The Alliance for Automotive Innovation, using a narrower assembly-plant concept, says 20 automakers operate 55 light-vehicle assembly plants in 15 states.[2] Average pay near $118,000 reflects skilled, heavily unionized manufacturing labor.[6] The federal Small Business Administration (SBA) sets the "small" threshold at 1,500 employees — high for manufacturing, and a signal that this is an industry of giants.[7]
The undercount caveat runs the opposite way here. Many industries are undercounted because they are dominated by tiny or individual operators; auto assembly is the reverse — a handful of huge firms, well captured by the Census. What the code understates is the industry's true footprint: the ~237,000 assembly jobs sit atop roughly 1 million total motor-vehicle-and-parts manufacturing jobs, and the broader auto sector (parts, dealers, finance, service) supports on the order of 10 million U.S. jobs, or about 5% of private-sector employment.[2] Read 336110 as "final assembly," not "the auto industry."
For scale on the demand side: Americans bought about 16.2 million new light vehicles in 2025, up ~2.4% from 2024.[8] But U.S. production is smaller than U.S. sales — domestic plants build roughly 10 million light vehicles a year (down from an average near 11.6 million in the five pre-pandemic years), with the balance imported, mostly from Mexico, Canada, Japan, and Korea.[9] For context on cyclicality, U.S. light-vehicle sales fell to just 10.2 million units in 2009 during the financial crisis — a 37% drop from pre-crisis levels.[10]
4. The investable universe
Unlike many industries, this one has a clean set of listed pure-plays. Scale figures below are approximate and drawn from 2025 results and mid-2026 market values; treat them as orientation, not precision.
| Company | Ticker | Listing | Approx. scale |
|---|---|---|---|
| General Motors | GM | NYSE | ~$185B revenue (2025); ~2.9M U.S. vehicles, ~17% U.S. share; ~$68B market cap[3][11][14] |
| Ford Motor | F | NYSE | Record $187.3B revenue (2025) but $8.2B net loss; ~2.18M U.S. vehicles; ~$56B market cap[12][14] |
| Tesla | TSLA | Nasdaq | $94.8B total revenue (2025), $69.5B automotive; ~1.64M global deliveries; U.S. EV leader (~46%); ~$1.3T market cap[13][31][14] |
| Stellantis | STLA | NYSE / Euronext / Milan | Owner of Jeep/Ram/Dodge/Chrysler; ~1.3M U.S. vehicles; ~$30B market cap[31][14] |
| Rivian | RIVN | Nasdaq | EV startup; 42,247 deliveries (FY2025), first full-year gross profit but $3.6B net loss; ~$25B market cap[15][14] |
| Lucid Group | LCID | Nasdaq | EV startup; 15,841 deliveries (2025), $2.7B net loss; backed by Saudi Public Investment Fund; ~$2.3B market cap[15][14] |
Foreign-owned major U.S. producers. Toyota (ADR: TM), Honda (ADR: HMC), Hyundai and Kia, Nissan, Subaru, Volkswagen, BMW, and Mercedes-Benz operate some of the largest U.S. assembly plants — together building roughly 4.9 million vehicles in the U.S. in a recent year — but their shares trade on home exchanges or as ADRs, not as domestic auto stocks.[4] Experian's registration-based market-share data shows Toyota at 16.5% and Ford at 12.6%; measurement methods (manufacturer sales, registrations, fleet deliveries, timing conventions) produce different "market share" numbers.[11]
Private and other owners. There is little for a retail private investor to buy directly; assembling cars requires billions in plants and tooling. Private exposure typically runs through parts suppliers (many public: Aptiv, BorgWarner, Magna, Lear), dealer groups (AutoNation, Penske, Group 1), battery joint ventures (Ultium, BlueOval SK, Honda-LG), and venture/private-equity stakes in EV and autonomy startups. That last category is a graveyard as much as an opportunity — Fisker, Canoo, Lordstown, and Nikola all failed — so it is speculative capital, not core exposure.
There is no pure "336110" exchange-traded fund (ETF). Broad exposure comes via consumer-discretionary index funds or thematic EV/mobility ETFs (for example DRIV, KARS, IDRV) that hold the whole value chain — automakers, suppliers, chipmakers, and miners — rather than assemblers alone.
5. How the money works
Auto assembly is a high-fixed-cost, high-volume, cyclical business. An owner earns the spread between what a vehicle sells for and what it costs to build, multiplied by volume, minus enormous fixed costs — plants, tooling, engineering, and labor that must be paid whether the line runs full or half-empty. The metrics that matter:
- Unit volume and capacity utilization. Because fixed costs are so large, factories need high utilization (roughly 80%+) to cover them; a plant running well below capacity bleeds cash. Small swings in volume produce large swings in profit — this is operating leverage, and it cuts both ways.
- Cost structure. Material and component costs dominate. GM reports that material cost represented approximately two-thirds of 2025 automotive cost of sales; the balance included labor, depreciation and amortization, engineering, freight, warranty, and recall campaigns.[3]
- Average transaction price (ATP) and incentives. ATP is what buyers actually pay after discounts. New-vehicle ATP crossed $50,000 for the first time in September 2025 and hit a record ~$50,326 in December.[16] When demand softens, makers add incentives (rebates, cheap financing) that lower the effective price and compress margins.
- Gross profit per vehicle and mix. Trucks and SUVs earn far more than small cars, so mix is decisive. GM discloses that the variable profit of its trucks, crossovers, and cars is approximately 160%, 40%, and 60%, respectively, of its weighted-average GM North America portfolio vehicle — explaining why full-size pickups and SUVs can subsidize smaller vehicles and technology programs.[3] At the 2024 peak, GM earned roughly $5,122 of gross profit per vehicle versus Ford's $3,193; under 2025's tariff and cost pressure, Ford's per-unit gross profit briefly turned negative.[17]
- Operating margin (EBIT). GM's North America adjusted EBIT margin was 6.8% in 2025, down from 9.2% in 2024, with the company targeting 8–10%.[18] Ford's company-wide adjusted EBIT margin was 3.6% in 2025, but segment results varied dramatically: Ford Blue (traditional vehicles) earned 3.0%, commercial-focused Ford Pro earned 10.3%, and Ford Model e (EVs) lost money at a negative 72.1% margin.[12] Mid-to-high single digits is a good year for a mass-market assembler.
- Capital expenditure. Plant and tooling needs remain large even for incumbents. GM incurred $9.2 billion of automotive capital expenditure in 2025, after $10.7 billion in 2024.[3]
- Captive finance. GM Financial and Ford Credit lend to buyers and dealers. These finance arms generate steadier profit that partly smooths the violently cyclical manufacturing side — a structural feature, not a footnote. Consolidated OEM earnings therefore combine a cyclical industrial manufacturer with a leveraged lender; industrial cash, debt, and margin should be separated from the finance subsidiary.
- Regulatory credits. Makers that beat emissions targets can sell credits to those that miss. Tesla booked ~$1.99 billion of regulatory-credit revenue in 2025 — nearly pure margin — but that stream is shrinking as U.S. rules loosen (down 28% year over year).[13]
- EV economics. For legacy makers, EVs still lose money per unit. GM took $7.6 billion in EV-related charges in 2025 as demand disappointed and tax rules changed, and Ford's EV unit has lost billions.[19] Tesla is profitable on EVs but its margins have compressed as prices fell; Tesla reported a 17.8% automotive gross margin in 2025, down from 18.4% in 2024, though this figure is before operating expenses and includes regulatory-credit revenue, so it is not comparable with Ford or GM segment EBIT.[13]
The through-line: money is made by keeping plants full, holding pricing, tilting mix toward trucks and SUVs, and financing the customer — while the EV transition currently subtracts from profit for everyone except Tesla.
6. What drives demand
- The economy and jobs. New-vehicle sales track consumer income, employment, and confidence. Autos are the classic discretionary big-ticket purchase — the first thing households defer in a downturn.
- Interest rates and affordability. Most vehicles are financed, so loan rates directly shape monthly payments and therefore demand. With ATP above $50,000, affordability is stretched, and rate moves swing buyers in and out of the market.[16]
- The replacement cycle. The average U.S. vehicle on the road reached 12.8 years in 2025, creating durable pent-up replacement demand that eventually must be met regardless of the cycle.[20] But this also demonstrates consumers' ability to postpone purchases.
- Mix. The U.S. market is structurally truck- and SUV-heavy. EPA reports that 34% of model-year 2024 production was regulated as cars and 66% as trucks, with truck-classified SUVs alone accounting for half of production ("truck" in this context is a regulatory category, not a synonym for pickup).[21] Fuel prices shift the mix between thirsty trucks and efficient cars, but rarely change total volume much.
- Incentives and tax policy. The federal EV tax credit's expiration on September 30, 2025 pulled EV demand sharply forward. Battery-EV share reached a record 12% in September 2025, then collapsed to below 6% in each remaining month of the year.[22] For 2025 as a whole, hybrids, BEVs, and plug-in hybrids together represented about 22% of U.S. light-duty sales; BEVs were 7.5% and plug-in hybrids 1.6%, with conventional hybrids supplying most of the remaining electrified share.[22] Policy can move demand across months violently even when the annual trend is calm.
- Fleet and commercial buyers (rental companies, businesses, government) add a layer of demand less tied to consumer mood.
7. Regulation
Auto assembly is one of the most heavily regulated industries in America, and the rules shifted dramatically in 2025–2026:
- Fuel economy (CAFE). The National Highway Traffic Safety Administration (NHTSA) runs the Corporate Average Fuel Economy (CAFE) program. A 2024 rule pushed toward roughly 50 miles per gallon by model year 2031; in December 2025 NHTSA proposed rolling that back sharply, to about 34.5 mpg by 2031 (the "SAFE III" approach).[23] Most automakers publicly supported the rollback.[24]
- Tailpipe emissions. In February 2026 the Environmental Protection Agency (EPA) finalized rescission of the greenhouse-gas endangerment finding and its motor-vehicle GHG emissions rules, while stating that traditional air-pollutant requirements remain in force.[25]
- State authority. In June 2025 Congress revoked California's Clean Air Act waivers, removing the legal basis for California and aligned states to set stricter tailpipe standards or mandate EV sales.[24]
- Trade (Section 232). A 25% tariff on imported vehicles took effect April 3, 2025 and on many imported parts May 3, 2025, with partial exemptions for the U.S. content of vehicles that comply with the U.S.-Mexico-Canada Agreement (USMCA) — which requires 75% regional value content.[26][27] GM recorded $3.1 billion of tariff-related material and freight cost in 2025.[3] This reshaped sourcing and squeezed margins across the industry.
- EV incentives. The federal $7,500 new-EV and $4,000 used-EV tax credits (Internal Revenue Code sections 30D and 45W) ended September 30, 2025 under the "One Big Beautiful Bill" law.[28]
- Safety and recalls. NHTSA also sets crash and safety standards (FMVSS) and oversees recalls — a constant source of cost and liability. GM incurred $1.3 billion of increased warranty and campaign costs in 2025.[3]
- Labor. Plants are governed by federal labor law and, at the Detroit Three, by United Auto Workers (UAW) national contracts.
The net regulatory picture in 2026: looser fuel-economy and emissions rules (a cost tailwind and reduced pressure to sell EVs), but higher trade barriers and no EV purchase subsidy (both headwinds).
8. Competitive dynamics and consolidation
The industry is moderately concentrated. Federal concentration data for 2022 put the top four firms at 58.3% of revenue, the top eight at 85.5%, and the top 20 at 99.5%, with a Herfindahl-Hirschman Index (HHI — a standard concentration measure) of about 1,186.[5] Barriers to entry are steep: billions in capital, decades of brand equity, sprawling dealer networks, and regulatory complexity.
The competitive map has three fronts. First, the Detroit Three versus transplants — foreign-owned plants in the South have steadily taken share from Detroit for decades. Second, legacy makers versus Tesla in EVs, where Tesla still holds roughly 46% of U.S. EV sales.[31] Third, a wave of EV startups, most of which failed (Fisker, Canoo, Lordstown, Nikola); Rivian and Lucid survive but burn cash.[15]
Consolidation is a recurring theme — Chrysler became Fiat Chrysler and then, in 2021, merged with France's PSA to form Stellantis. The forward pressure now is toward shared costs: battery joint ventures (GM's Ultium, Ford's BlueOval SK, Honda-LG), shared EV platforms, and software partnerships, because no single maker can easily fund the EV and autonomy transition alone. Looming over all of it is Chinese competition — BYD and other Chinese EV makers dominate globally on cost but are largely kept out of the U.S. by tariffs, a strategic risk that is contained at home but intense in export markets.
9. Risks
- Cyclicality. Sales swing hard with the economy, and high fixed costs amplify every swing into a bigger profit swing. U.S. light-vehicle sales dropped to 10.2 million in 2009 versus 16.2 million in 2025 — a 37% trough-to-recovery swing.[10][8]
- Trade and tariffs. The 25% Section 232 tariffs raise input costs and disrupt supply chains; GM alone recorded $3.1 billion of tariff-related costs in 2025, and the policy remains a variable that can change with an election or negotiation.[3][26]
- The EV transition. Enormous capital is committed to EVs just as subsidy-driven demand softened; legacy makers lose money per EV, face possible stranded investment, yet also risk falling behind if EV demand reaccelerates. It is a lose-money-now, uncertain-payoff bet.[19]
- Chinese competition. Cost-advantaged Chinese EVs pressure global markets and could reach the U.S. if trade barriers ease.
- Labor costs. The 2023 UAW contracts delivered roughly 25% base-wage increases through April 2028, with top wages rising more than 30% to over $40 per hour and starting wages up 68% to over $28 per hour, while restoring cost-of-living adjustments and bringing EV and battery jobs under the union — raising structural costs and setting up the next strike risk in 2028.[29][30]
- Supply chain. The industry remains exposed to single-source shocks — semiconductor shortages (2021–22), critical-mineral supply, and events like the 2025 Novelis aluminum fire that cost Ford ~$2 billion.[12][32]
- Affordability. With ATP above $50,000 and financing costs elevated, the mass-market buyer is increasingly priced out.[16]
- Technology and capital intensity. Autonomy, robotaxis, and software-defined vehicles demand heavy, uncertain spending; missteps are expensive.
- Regulatory whiplash. Rules have swung sharply (CAFE rollback, credits ending, California waivers revoked), making multi-year plant and product planning harder.
10. How to invest, and the outlook
Public routes.
- Legacy value/dividend plays — GM (GM), Ford (F), Stellantis (STLA). These trade at low single-digit price-to-earnings multiples, pay dividends, buy back stock (GM authorized a fresh $6 billion buyback with 2025 results), and earn steady profit from captive finance — but they are cyclical and tariff-exposed, and Ford posted a large 2025 net loss on special items.[19][12] Value investors buy them for cash returns and cheapness; the risk is the cycle and policy.
- Growth/tech valuation — Tesla (TSLA). Priced far above traditional automakers, Tesla is as much an EV-plus-energy-plus-autonomy/AI bet as a car stock; its ~$1.3 trillion market value assumes success well beyond building cars.[14]
- Speculative EV pure-plays — Rivian (RIVN), Lucid (LCID). Pre-profit, cash-hungry, and dilution-prone; suitable only as high-risk, high-variance positions.[15]
- Foreign makers via ADRs — Toyota (TM), Honda (HMC) and others — for exposure to the disciplined transplant model.
- Adjacent exposure — parts suppliers, dealer groups, and thematic EV ETFs (DRIV, KARS, IDRV) spread the bet across the value chain rather than a single assembler.
Private routes. Direct ownership of an assembler is impractical for most investors. Realistic private exposure runs through suppliers, dealer groups, aftermarket businesses, battery and charging infrastructure, and venture/PE stakes in EV and autonomy startups — the last being speculative given the sector's failure rate. A private investor should diligence customer and platform concentration, tooling ownership, take-or-pay commitments, union and pension obligations, environmental liabilities, warranty and recall indemnities, launch history, supplier liquidity, and whether EBITDA was earned at normal production and incentive levels.
A note on data. The most common analytical error is to label U.S. retail vehicle sales, consolidated OEM revenue, or the entire "auto industry" as NAICS 336110. The code measures domestic production establishments. It excludes imports from output, includes exports, counts foreign-owned U.S. plants, and omits much of the supplier, dealer, repair, and finance ecosystem.
Near-term drivers to watch (these are forward-looking judgments, not settled facts): the trajectory of Section 232 tariffs and any tariff relief; the interest-rate path and its effect on affordability; how far EV demand falls now that the $7,500 credit is gone; the cost relief from looser CAFE and emissions rules; pricing discipline versus rising incentives; and capital returns from the cash-generative legacy makers.
Outlook. This is a mature, cyclical, capital-intensive industry entering 2026 with crosscurrents: a genuine cost tailwind from looser fuel-economy and emissions rules, offset by higher tariffs, the loss of EV subsidies, elevated affordability barriers, and money-losing EV programs. Expect continued margin pressure and consolidation pressure in the near term, with the winners being the makers that hold pricing, keep plants full, tilt toward trucks and SUVs, and manage the EV transition without over-committing capital. The long-run question — whether legacy makers can build EVs profitably before Chinese competition and technology shifts erode their franchises — remains open.
