Commercial and Industrial Machinery and Equipment Rental and Leasing

U.S. industry-group primer — NAICS 2022 code 5324

NAICS = North American Industry Classification System, the U.S. government's standard code for industries. This is the four-digit "industry group," one rung above the five-digit industries beneath it. Figures carry a numbered marker keyed to the Sources list. Where a federal figure is genuinely unavailable it is flagged, not invented.

---

1. Overview

This industry group counts the businesses that own expensive, depreciating machines and rent them out to other businesses — no operator supplied, no consumer trade, no vehicles or buildings. It bundles three very different fleets under one federal code:

• 53241 rents heavy iron and transport equipment — bulldozers, excavators, and cranes to contractors; aircraft, railcars, and shipping containers to airlines, railroads, and ocean carriers.[4]
• 53249 rents "everything else" commercial and industrial gear — hospital medical devices, electronic test-and-measurement instruments, diesel generators and temporary power, modular buildings and portable storage.[6]
• 53242 rents office machinery — copiers and multifunction printers (MFP = one device that prints, scans, copies, and faxes), computers, servers, and office furniture.[5]

They share a filing cabinet — the Census Bureau's Sector 53, "Real Estate and Rental and Leasing" — and a genuine common economic engine: buy a costly hard asset, finance it with debt, keep it earning rent, and recover a residual (resale) value when you sell it. But the label misleads the same way for all three, so say it plainly up front: none of this is real estate, and none of it is a REIT. (REIT = real estate investment trust, the pass-through structure that owns income property, pays little corporate tax, and must distribute ~90% of taxable income.) There is no property here, so no NOI (net operating income), no cap rate (capitalization rate — a property's income divided by its price), and no FFO/AFFO (funds from operations / adjusted funds from operations — the cash-earnings measures REIT investors use). The operators are ordinary taxable corporations, and the right vocabulary is fleet utilization, lease rates, residual value, financing spread, and leverage — not rate base, not commodity prices, not FFO.

Why an investor cares. Three capital-heavy, cyclical, cash-generative businesses that run the same underlying machine but differ sharply in size, who owns them, and — most striking — which direction their ownership is traveling relative to public markets. One cross-cutting truth dominates the group: private capital is winning almost everywhere. Infrastructure funds and private equity are buying the biggest asset pools out of public hands across transport equipment and the "other" bucket — with one loud exception, heavy construction equipment, where public consolidators are getting bigger and even moving listings onto U.S. exchanges. Meanwhile the office child is a slow-declining income play. The contrast across the three is the whole point of this primer, so we lead with it.

2. What's inside — the three children and how they differ

The group is a barbell: two near-equal heavyweights (53241 and 53249, ~52% and ~46% of receipts) and one rounding error (53242, ~3%). But revenue share hides the real texture — 53249 employs almost double the people of 53241 on slightly less revenue, because renting hospital pumps and calibrating test instruments is labor- and service-intensive, while leasing a jet or a railcar is almost pure balance sheet. The three children sum dollar-exact to the group totals (see Section 3), so the split below is clean.[2][4][5][6]

*53241's ~$625K blended figure hides a ~6× internal gap: the transport side (aircraft/rail/containers) runs ~$2.8M of revenue per employee — nearly pure balance sheet — while the heavy-equipment side runs ~$0.49M. CR4 = four-firm concentration ratio (share of the largest four); HHI = Herfindahl-Hirschman Index; OEM = original equipment manufacturer; PE = private equity. Tickers, yields, and valuation multiples are held for Sections 4 and 10 per house style.

The single most important contrast is the public-market direction row. Across two of the three children — and inside the transport half of the third — the largest asset pools are steadily leaving public markets for private and infrastructure capital: the two biggest container lessors went private (Triton to Brookfield, 2023; Textainer to Stonepeak, 2024), aircraft lessor Air Lease went private in 2026, and in the "other" bucket private equity took the category leaders — Agiliti (movable medical, to Thomas H. Lee, 2024), Electro Rent (test instruments, Platinum Equity), and Aggreko (temporary power, I Squared + TDR).[13][17][21][22] The exception that proves the rule is heavy construction equipment, where the public champions are getting bigger: Herc bought H&E in 2025, and Sunbelt moved its primary listing from London to New York in March 2026.[18][19] Same four-digit code; near-opposite capital flows. An investor's first decision is which flow to ride.

The second contrast is what the money actually is. All three run a hard-asset engine, but 53241's transport side and most of 53249 and 53242 also carry a financing business bolted on — and that financing business is far larger than the rental line the Census measures (Section 3). The children diverge on whether you are buying an operating business (utilization, throughput, labor — heavy equipment, medical rental, modular) or a financial one (spread, leverage, credit — aircraft, railcars, copier and office-gear leasing).

---

3. How big it is

Our authoritative ingested federal figures for the group, NAICS 5324 (United States):

The three children reconcile to these totals to the dollar on receipts ($49.62B + $43.78B + $2.57B = $95.97B), establishments, employees, and payroll; only the firm count differs slightly (the children sum to 8,942 because a firm active in more than one child is counted in each but deduplicated to 8,859 at the group level).[4][5][6] The group earns roughly $440,000 of revenue per employee and pays ~$82,000 per employee — high for a service industry, but a blended figure spanning a near-pure-balance-sheet transport-leasing niche and a technician-heavy industrial-rental one. The average firm books ~$10.8 million of revenue.

Concentration (2022 Economic Census, receipts basis):[2]

A subtle but important point: the group's top-4 share (22.0%) is lower than every child's (33.5%, 23.2%, 33.5%). That is not a paradox — it is arithmetic. The three children have different leaders (the biggest aircraft lessor is not the biggest crane renter is not the biggest copier lessor), so combining the fields spreads the largest four firms across a much wider revenue base and dilutes measured concentration. The group HHI of 194.3 sits far below the ~1,500 mark U.S. antitrust agencies treat as the floor of a "concentrated" market — but that number describes the aggregate, not the arenas an investor actually competes in. Within individual niches — aircraft leasing, ocean containers, temporary power, modular space, movable medical equipment — a few national platforms dominate. The group is a collection of tight oligopolies that looks fragmented only when you blend unrelated markets together.

The undercount caveat — this $95.97 billion is a floor, understated three ways, and none of them is the residential-real-estate story. Unlike apartments — where individual small landlords own most units and vanish from business statistics — this group's undercount is not driven by pass-through individual ownership. It is understated because:

1. The finance-lease economy is booked in another sector. When a lessor bundles a loan with the lease — a finance or "$1-buyout" lease, the way most copier and much equipment financing is actually written — Census reclassifies it into 522220 Sales Financing in the Finance sector, not here. That is where the big captive finance arms (Xerox, Canon, John Deere Financial, Caterpillar Financial) and bank lessors are counted. The Equipment Leasing and Finance Association (ELFA) sizes total U.S. equipment finance near $1.3 trillion of new business a year; this $95.97 billion rental line is the operating-rental residue left after that far larger financial layer is stripped out to code 522220.[8]
2. The largest transport lessors are domiciled offshore. The Economic Census counts U.S.-located establishments' domestic receipts, but the biggest aircraft and container lessors are legally domiciled offshore for tax reasons (aircraft in Ireland, containers in Bermuda) even though they trade on U.S. exchanges. Counting the fleet rather than domestic receipts pushes the relevant asset base into the hundreds of billions.[4]
3. A real but modest individual-operator tail exists. The 2022 Nonemployer Statistics show 35,689 nonemployer businesses in NAICS 5324 with $5.23 billion of receipts — one-person and micro fleet-owners with no paid staff who never appear in the ~8,900-firm employer count.[7] Meaningful, but an order of magnitude smaller than the finance-sector leakage.

There is also no federal "number of rental units" — a modular classroom, an infusion pump, a jet engine, and a spectrum analyzer are not comparable units, and no unified fleet count is published. Read $95.97 billion as a floor for the narrow rental core, not the whole economy these operators touch.

4. The investable universe

Value concentrates very differently across the three children, and the public menus point in opposite directions.

53241 — split, and mostly shrinking

• Heavy construction equipment: a growing public menu. The listed platforms are the industry's champions — United Rentals (URI), ~$16B revenue and the #1 global fleet; Sunbelt Rentals (SUNB), ~$11B and newly NYSE-listed; Herc Holdings (HRI), a more leveraged consolidator after buying H&E; and EquipmentShare (EQPT), a telematics-led grower.[16][18][19] Below them sit thousands of independent yards and OEM-dealer rental desks.
• Transport equipment: a shrinking public menu. Aircraft leader AerCap (AER) and railcar lessors GATX (GATX) and Trinity Industries (TRN) remain listed, but containers have no meaningful public pure-play left (Triton and Textainer both went private).[12][13] Major private/institutional owners span aircraft (SMBC Aviation Capital, Avolon, Carlyle Aviation), railcars (Berkshire's Union Tank Car, ITE's AITX), and containers (Brookfield, Stonepeak).

53249 — no pure-play; mostly private

• Nearest listed operators: WillScot (WSC), modular space and portable storage (~$2.3B revenue, ~304,000 units); McGrath RentCorp (MGRC), modular plus the cleanest in-code electronic-test rental (TRS-RenTelco); and Transcat (TRNS), partial test-and-measurement exposure.[14][15]
• Indirect public exposure runs through diversified financials — manufacturer captives Deere (DE) and Caterpillar (CAT), bank lessors, and equipment-finance business development companies (BDC = a listed vehicle that lends to and invests in mid-sized companies), such as SLR Investment (SLRC) and Trinity Capital (TRIN).[20]
• Where the industry actually sits — major private owners: Agiliti (movable medical, Thomas H. Lee); Electro Rent (test, Platinum Equity); Aggreko (temporary power, I Squared + TDR); US Med-Equip (hospital equipment, Freeman Spogli); plus thousands of local generator, scaffolding, and specialty firms.[17][21][22]

53242 — no pure-play, no REIT, a declining-income field

Public exposure comes only through diversified hardware/finance companies where office leasing is one slice — Xerox (XRX), HP (HPQ), Canon (CAJ), Pitney Bowes (PBI), and Tokyo-listed Ricoh and Konica Minolta. These are mature, cash-generative value/turnaround names, not growth.[9] The purer exposure is private: vendor-finance and independent lessors (DLL, GreatAmerica, CSI Leasing, PEAC) and private-equity dealer roll-ups (DEX Imaging, Flex Technology Group, Visual Edge).

The pattern across the group: the stable, contracted, hard-asset cash flows of transport, medical, power, and modular are exactly what infrastructure funds and PE want, so those assets keep migrating out of public markets; the fragmented long tail of heavy construction equipment is exactly what public consolidators want, so those platforms keep getting bigger and stay listed. An investor picks the child by the flow they want to ride — and in two of three, the public door is closing.

---

5. How the money works

All three children run the same underlying machine — own a depreciating hard asset, finance it, keep it earning, recover a residual on sale — and none is a REIT, so all are valued on cash earnings and asset value rather than FFO/AFFO or cap rates. Two profit engines run through the group, mixed in different proportions:

Engine one — operating rental (throughput). Buy an asset, keep it on your balance sheet, rent it repeatedly across short contracts, then sell it into the used market:

Rental revenue ≈ average fleet cost × utilization × rental rate

The master metric is utilization — either time utilization (share of fleet on rent) or dollar utilization (annual rental revenue ÷ OEC, original equipment cost — the true yield on invested capital). Because branches, technicians, and depreciation are largely fixed, a modest utilization drop cuts profit disproportionately. Residual (resale) value is a real earnings variable — used-equipment prices make or break returns, and they softened into late 2025.[20] This engine dominates the heavy-equipment side of 53241 and the rental portion of 53249 (medical, modular, generators, test gear). These firms are judged on EBITDA (earnings before interest, taxes, depreciation, and amortization), ROIC (return on invested capital), and free cash flow — with the redeeming feature that capex is discretionary: when demand slows, operators stop buying fleet and free cash flow surges, making the model counter-cyclically cash-generative.

Engine two — financing spread (bank-like). Alongside true rental sits the far larger business of funding customers' equipment: the lessor borrows, signs fixed-rate lease contracts, and keeps the gap. The profit is lease yield − cost of funds − credit losses − servicing — which makes the whole thing directly interest-rate-sensitive. A 2024 industry survey showed the squeeze as rates rose: portfolio yield ~7.4%, funding cost ~4.8%, spread just ~2.6%.[8] This engine dominates 53241's transport side (aircraft/rail/container leasing runs ~97–99% utilization at multi-year lease terms, valued on price-to-book / net asset value) and 53242's office-equipment leasing (where a per-page "click charge" managed-print annuity is the stickiest, highest-margin money). Lease accounting under ASC 842 (operating vs. finance/sales-type classification) changes the timing of reported profit on both — so reconcile earnings to cash, because sales-type accounting can book profit years before the cash arrives.

Where they converge: residual-value risk, heavy capital intensity, high leverage, and interest-rate sensitivity everywhere; plus a shared secular tailwind — the rent-vs-own shift. Airlines now lease ~58% of the world jet fleet (up from ~2% in the early 1980s); contractors rent ~57–60% of U.S. construction equipment, near a record; and roughly 82% of firms that acquire equipment finance rather than buy it outright.[8][10] Every point of penetration shifts spending from ownership to rental independent of the underlying volume cycle.

The one clean real-estate angle in the whole group belongs to heavy equipment: the rental branches themselves — freestanding equipment yards — are emerging as a net-lease property class, where an investor owns the yard and leases it back to the operator on a long triple-net lease, earning property rent with no fleet or residual risk. That is the only route in this group that behaves like a traditional landlord strategy.

---

6. What drives demand

Shared across all three children:

• The rent-vs-own penetration shift — the secular engine everywhere (leased jets ~58%; rented construction equipment ~57–60%; ~82% of equipment acquisitions financed).[8][10]
• The business capital-expenditure cycle — rental and finance are pro-cyclical, riding a ~$2.3-trillion annual U.S. equipment-and-software investment pool.[8]
• Interest rates — two-edged — higher rates make renting more attractive to customers but raise lessors' own funding costs and squeeze financing spreads.
• Tax depreciation — the 2025 One Big Beautiful Bill Act (OBBBA) permanently restored 100% bonus depreciation for qualifying equipment, a tailwind for fleet buyers (and a mild nudge toward buying for strong customers).[24]

Child-specific: Transport (53241) — long-run air-travel and rail-freight growth, and, paradoxically, OEM production shortfalls (when Boeing/Airbus fall behind and engines are grounded, used aircraft turn scarce and lease rates rise for lessors already holding metal). Heavy equipment (53241) — non-residential and infrastructure construction, megaprojects (data centers, semiconductor fabs, battery plants), the 2021 IIJA (Infrastructure Investment and Jobs Act) in peak-spend, and emissions rules pushing renters toward newer machines. Other C&I (53249) — healthcare activity and hospital census, technology refresh in fast-evolving test and medical gear, temporary power for outages and events, and modular demand for schools and disaster response. Office (53242) — a secular decline in the hardware base (pages printed down ~20% since the pandemic), offset periodically by PC-refresh waves.[8][9]

---

7. Regulation

Shared across all three: none is rent-regulated (no fair-housing, rent-control, or zoning regime applies) and none is taxed as a REIT, so none carries a ~90%-distribution mandate. The governing law is commercial-finance, tax, and accounting: lease accounting under ASC 842 (operating vs. finance classification); the Uniform Commercial Code (UCC) Articles 2A and 9 on true-lease-vs-disguised-loan and security interests; and federal tax depreciation (bonus depreciation and §179, with OBBBA's permanent 100% bonus restoration). Consumer-finance rules (the CFPB's Regulation M) generally do not apply because these are business-to-business contracts.[24]

Child-specific regimes that bite: Transport (53241) — the Cape Town Convention and U.S. Bankruptcy Code §§1110/1168 give lessors accelerated repossession rights (a core reason transport-lease debt is cheap and investment-grade); FAA/FRA safety and registry rules; the Jones Act on domestic vessels; and the global minimum tax (Pillar Two) as a prospective risk to offshore lessors.[4] Heavy equipment (53241) — EPA nonroad-diesel Tier 4 standards drive fleet replacement, OSHA governs crane-operator certification (supplying an operator reclassifies the work out of this group), and HSR (Hart-Scott-Rodino) antitrust review applies to active consolidation. Other C&I (53249) — medical-equipment rental intersects FDA device rules, and national combinations draw FTC scrutiny (the FTC blocked WillScot's $3.8B bid for McGrath in 2024).[23] Office (53242) — data-security and e-waste obligations on the drives inside returned copiers, a patchwork of state commercial-financing disclosure laws, and CECL (current expected credit losses) reserving for the finance books.

---

8. Consolidation

Scale is the game across the group, but it plays out in near-opposite directions — which is why the aggregate HHI (194.3) looks tame while each arena is a tightening oligopoly.

Private capital is the dominant consolidation vector. In transport, infrastructure funds and PE took the biggest asset pools private (Brookfield/Triton 2023, Stonepeak/Textainer 2024, the Sumitomo-Apollo-Brookfield group's Air Lease buyout 2026) — the competitive weapon being cost of capital, where a small borrowing edge compounds across a multibillion-dollar fleet.[12][13] In the "other" bucket, PE bought the category leaders out of public markets (Agiliti, Electro Rent, Aggreko) and combines regional operators beneath them, reducing public exposure over time.[17][21][22] In office, a shrinking pie forces consolidation on every level — OEM mergers (Xerox closed its ~$1.5B Lexmark acquisition in 2025), finance-platform deals, and PE dealer roll-ups chasing recurring managed-print revenue.[9]

The exception is heavy construction equipment, which consolidates into bigger public platforms: Herc outbid United Rentals for H&E in 2025 (a ~$4.8B deal), and Sunbelt moved its primary listing to New York in 2026.[18][19] Here the fragmented long tail is the prize and public scale is the weapon — cheaper purchasing, branch density, national accounts, and telematics — while local operators persist because heavy machines are costly to transport.

The reconciliation with Section 3: within each tightly-defined arena the leaders loom large, but across the combined group the top four hold only ~22%, because each arena's leaders are different companies. The group is an oligopoly several times over, not once.

---

9. Risks

Shared across all three children:

• Interest-rate and refinancing risk — the lead risk everywhere. For the finance-heavy niches (transport, office), earnings are a spread that compresses when rates rise and debt reprices faster than fixed lease revenue; for the rental-heavy niches (heavy equipment, medical, modular), rates hit through both demand (delayed projects) and fleet-financing cost. Refinancing tens of billions of dollars through market windows is perilous if credit freezes.
• Residual-value risk — the core hard-asset bet on every side. A retirement wave, technology shift, or oversupply can crater resale values and force write-downs (container lessors cut residual assumptions in 2025; used heavy-equipment values softened into late 2025; WillScot took ~$302M of accelerated depreciation in 2025).[14][20]
• Cyclicality and customer credit — airlines, contractors, hospitals, and small businesses are all cyclical and default-prone; a downturn brings deferrals and repossessions at once.
• Utilization / oversupply — idle fleet is pure cost, and equipment ordered in a boom can arrive after demand cools, hitting utilization, rate, and residuals simultaneously.
• Accounting quality — gains on fleet sales, impairments, changes in useful lives, and up-front sales-type lease profit can make reported net income misleading. Focus on recurring earnings and cash, not headline profit.

Child-specific: Transport (53241) — geopolitical and sanctions risk with catastrophic-loss potential (400+ aircraft stranded in Russia after 2022 triggered multi-billion-dollar charges). Heavy equipment (53241) — severe operating leverage on the construction cycle, concentration in megaprojects (a data-center pullback would remove a key growth support), and mundane theft of portable machines. Other C&I (53249) — technology obsolescence in fast-moving test/medical gear and FDA exposure. Office (53242) — a permanently eroding print base, the group's one genuinely existential demand risk.

---

10. How to invest, and outlook

Public-market routes need three different lenses. Heavy equipment (53241) is the deepest public menu — United Rentals (URI) and Sunbelt (SUNB) for scale and free cash flow, Herc (HRI) as a leveraged consolidation bet, EquipmentShare (EQPT) for telematics growth — valued on EV/EBITDA (enterprise value to EBITDA), price-to-free-cash-flow, ROIC, net-debt/EBITDA, and EV/fleet-OEC, never FFO or cap rates; yields are token and the case is earnings growth, consolidation, and buybacks, so cycle entry point matters. Transport (53241) is a short, shrinking menu — AerCap (AER) in aircraft, GATX (GATX) and Trinity (TRN) in railcars, containers effectively off the public menu — valued on price-to-book / price-to-NAV (NAV = net asset value, appraised fleet value plus other assets minus net debt), utilization, renewal pricing, and the debt-maturity ladder; yields are modest (~1–3%) precisely because there is no payout mandate and capital-intensive lessors create more value retaining capital or buying stock below NAV. Other C&I (53249) offers only partial pure-plays — WillScot (WSC), McGrath (MGRC), Transcat (TRNS) — plus indirect finance exposure via Deere (DE), Caterpillar (CAT), banks, and BDCs (SLRC, TRIN). Office (53242) is declining-industry income: Xerox (XRX), HP (HPQ), Canon (CAJ), Pitney Bowes (PBI) — judged on financing income, page-volume trends, dividend coverage, and free cash flow, valued on price-to-tangible-book and free-cash-flow yield. A high dividend yield unbacked by replacement capex is not a REIT distribution and should not be valued like one.

Private-market routes are where most of the group actually lives. Transport reaches the assets through infrastructure and equipment-leasing funds (Brookfield, Stonepeak, Apollo, Carlyle Aviation), asset-backed securities (ABS = bonds secured by pooled lease cash flows), and sale-leasebacks. The "other" bucket reaches it through sponsor-led PE platforms, equipment-backed private credit, and independent leasing books earning net spread. Office reaches it through dealer/managed-print roll-ups and lease-receivable portfolios. Heavy equipment adds the cleanest bridge to a traditional landlord strategy — net-lease ownership of the rental-yard real estate itself. Underwrite any fleet cohort-by-cohort: purchase cost, utilization ramp, rate, maintenance, economic (not accounting) life, downside residual, and matched funding — and separate the return from owning the equipment from the return from operating capability.

Outlook.

• Heavy equipment — modest growth on a solid secular base. The American Rental Association projects the broad U.S. rental market near ~$83.5 billion in 2026 (+3.6%), decelerating from the 2022–24 boom but positive, with megaprojects strong and conventional construction soft; penetration at a record and still rising.[10]
• Transport — the strongest near-term setup, but going private. Aircraft is the standout: OEM shortfalls and engine groundings keep jets scarce, supporting record lease rates and rising residuals; rail sits at ~97–99% utilization; containers are softer and now privately held.[4]
• Other C&I — constructive but cooling. Trade-association forecasts show ~6.2% real equipment-and-software investment growth for 2026 (after ~9.8% in 2025), financing demand softening, and privatization continuing.[8]
• Office — income and restructuring, not growth. The narrow print core keeps drifting lower while value migrates to the financing-and-service annuity (hidden in code 522220) and to whichever OEMs convert shrinking print into IT and workflow services.[9]

The master variables across all four are the interest-rate path (the Federal Reserve held policy at 3.50%–3.75% in mid-2026) and the asset-supply/residual cycle — a rate normalization would widen spreads and lift asset values across the group; a renewed spike would compress margins and refinancing capacity.[8]

Bottom line. NAICS 5324 bundles three hard-asset rental-and-leasing businesses that share one engine — own it, finance it, rent it, resell it — and one common truth: despite living in the "Real Estate and Rental and Leasing" sector, none is a REIT or a real-estate income play. They diverge on almost everything else, and the dominant cross-child pattern is a public menu that is closing: private and infrastructure capital is buying the biggest asset pools out of public markets across transport equipment and the "other" bucket, while office is a slow-declining income field — with heavy construction equipment the loud exception where listed champions keep getting bigger. Read the $95.97 billion as a floor: the far larger equipment-finance economy these operators touch is booked in the Finance sector, not here. Investors should choose the child by the flow they want to ride — the privatizing financial-leasing and specialty-rental tail, or the consolidating, still-public industrial-rental core — and value all of it on utilization, financing spread, residual value, and credit, never on cap rates or FFO.

Sourcing note: Sources 2 and 3 are our ingested U.S. federal statistics and are the authoritative figures for this industry group's core size and concentration. Sources 4–6 are the corresponding federal figures for the three child industries, synthesized here from the child primers — the four children/grandchildren reconcile dollar-exact to the group receipts, establishment, employment, and payroll totals. Company figures are primary SEC filings and press releases. Market-size, penetration, and equipment-finance figures from IATA, the American Rental Association, and ELFA (8, 10, 11) span markets broader than the four-digit NAICS code — industry-standard but not federal — and should not be substituted for the Census 5324 totals. Market capitalizations and dividend yields are approximate as of mid-July 2026 and move continuously. Forward-looking statements in Sections 9–10 are editorial judgment, not reported fact.
