CTOS vs URI: Which Is the Better Buy in 2026?
Last updated September 2026
Short answer
URI is the larger of the two ($61.63B market cap): the incumbent the market prices for continued execution (17.31x forward earnings, beta 1.80). CTOS is the smaller challenger ($2.02B), actually pricier on forward earnings (28.61x): more room to run, but more to prove. The real question is which set of drivers you believe, and whether owning one (or both) leaves you over-concentrated.
CTOS vs URI: the tie-breaker metrics
Same yardstick, side by side (as of September 2026). Valuation lined up like this is most meaningful for two names in the same corner of the market, which these are. Figures are approximate; verify before investing.
| Metric | CTOS | URI | What it tells you |
|---|---|---|---|
| Market cap | $2.02B | $61.63B | Size. The larger name is the incumbent; the smaller has more room to grow and more to prove. |
| Forward P/E | 28.61 | 17.31 | Valuation on next year's expected earnings, the same yardstick for both. Lower is cheaper for that growth; higher means the market is paying up. |
| Trailing P/E | 98.56 | 23.81 | Valuation on the last 12 months. A big drop from trailing to forward means the market expects earnings to jump, so more growth is already in the price. |
| Beta | 1.37 | 1.80 | Volatility vs the market. Above 1 swings harder than the index; below 1 is steadier. Higher beta means bigger drawdowns to hold through. |
| Price vs 52-week range | 52% of range | 60% of range | Where today's price sits between the 52-week low and high. Near the high is momentum with less margin of safety; near the low is out of favor or a discount, depending on why. |
| Price / book | 2.47 | 6.69 | How much you pay over book value. Very high can signal an asset-light, high-return business or a rich price. |
Reading it: URI is the cheaper of the two on forward earnings, but cheaper is not the same as better. Pair the valuation with growth (how far the forward P/E sits below the trailing P/E) and risk (beta) before you decide.
Before you buy: how CTOS and URI affect your concentration
The metrics above tell you which is the marginally better business. The bigger risk for most people is not picking the slightly worse stock, it is over-concentrating. CTOS and URI share themes, so owning both, or adding either to what you already hold, can quietly push a large share of your portfolio into one bet.
This is the part a generic comparison page cannot answer, because it depends on what you own. Connect your brokerage and Walnut shows your real, combined CTOS and URI exposure, flags overlap with your existing positions, and tells you if adding one would tip you past a concentration you are comfortable with, read-only by default, with your login staying at your broker.

What does Custom Truck One Source (CTOS) do?
Custom Truck One Source rents and sells specialized work trucks and equipment (bucket trucks, digger derricks, cranes, aerial lifts, service trucks) to the crews that build and maintain electric transmission and distribution lines, telecom networks, rail, forestry and waste operations across the US and Canada. It runs three segments: Equipment Rental Solutions (ERS), Truck and Equipment Sales (TES), and Aftermarket Parts and Services (APS). The pitch is a one-stop platform that spans rental, new and used sales, parts, and service, tied directly to long-cycle infrastructure demand drivers like grid modernization and the Infrastructure Investment and Jobs Act.
What does United Rentals (URI) do?
United Rentals, Inc. rents construction and industrial equipment (aerial work platforms, earthmoving machines, generators, pumps, trench safety gear, and a growing specialty fleet) across roughly 1,600 locations in North America and beyond. Rather than sell equipment, it earns recurring rental revenue by keeping a large fleet utilized, and it has grown for years through both organic expansion and a steady stream of acquisitions that consolidate a highly fragmented market. It holds an industry-leading share of the North American rental market, well ahead of the next-largest players.
CTOS vs URI: how do they differ?
Both fit overlapping themes, but they are not interchangeable. The useful comparison is which set of drivers and risks you want exposure to.
- CTOS drivers: Grid modernization and utility T&D demand; Rental fleet utilization and mix.
- URI drivers: Non-residential and infrastructure demand; Specialty segment mix shift.
Which fits which kind of investor
A faster-growing, richer-valued name usually swings harder, so it suits a longer horizon and a higher tolerance for volatility; a steadier, more cash-generative business suits a more conservative or income-minded investor. The honest test is which set of risks you could hold through a drawdown: CTOS is highly cyclical and capital-intensive, so a downturn in construction, utility or infrastructure spending would hit both rental demand and used-equipment resale values. For URI, uRI is deeply cyclical, so a recession or a sustained slowdown in construction and industrial activity would lower utilization, pricing, and profits.
CTOS or URI: which should you pick?
Growth-minded investors who believe the theme has years to run tend to accept the richer multiple for more upside; value-minded investors lean toward the cheaper forward earnings and steadier profile. Pick CTOS if you believe its drivers more; URI if you believe its. Many investors hold both, but since they share themes, that is a concentrated bet, not diversification. Decide deliberately and check overlap. For the full detail, see the CTOS and URI guides.
CTOS vs URI: the full fundamentals
CTOS. CTOS trades on EBITDA and leverage rather than earnings, since GAAP results have hovered around breakeven to small losses. The enterprise value is dominated by debt, so the equity is effectively a levered claim on a growing but capital-heavy rental platform. Whether the multiple re-rates depends heavily on hitting the sub-four-times leverage target.
URI. United Rentals reported record Q1 2026 revenue of about $3.99 billion (up roughly 7% year over year) with adjusted EPS near $9.71, and it raised full-year revenue and EBITDA guidance. The stock traded near $1,090 in early July 2026 after a strong run, putting its valuation modestly above its own history on a mid-20s to high-20s earnings multiple. Figures are approximate and drawn from public filings and market data.
Headline figures (approximate, July 2026): CTOS shows revenue (2025) ~$1.94B, revenue (q1 2026) ~$462M (+9%), adjusted ebitda (ltm) ~$408M, 2026 adj. ebitda guidance ~$415M-440M; URI shows revenue (ttm) ~$16.4B, fy2026 revenue guidance ~$16.9B to $17.4B, adjusted ebitda guidance (fy2026) ~$7.6B to $7.9B, market cap ~$68B.
The bottom line: CTOS vs URI
CTOS and URI are related but distinct: same themes, different businesses and risks. Neither wins in the abstract; the right pick is whichever thesis you actually believe, sized so you are not over-concentrated in one theme. Walnut can show your combined CTOS and URI exposure against your real portfolio. It is not an investment adviser.

FAQ
What is the difference between CTOS and URI?
+
Custom Truck One Source rents and sells specialized work trucks and equipment (bucket trucks, digger derricks, cranes, aerial lifts, service trucks) to the crews that build and maintain electric transmission and distribution lines, telecom networks, rail, forestry and waste operations across the US and Canada. United Rentals, Inc. They show up together because they share investment themes, but they are different businesses, so the better fit depends on which thesis you are expressing.
Is CTOS or URI the better stock?
+
Neither is universally better. URI is the larger incumbent; CTOS is the smaller challenger and looks pricier on forward earnings. Walnut is informational, not investment advice. Compare what each does, the tie-breaker metrics above, and the risks, then decide which fits your thesis and what you already own.
Which is cheaper, CTOS or URI?
+
On forward P/E (as of September 2026), CTOS trades at 28.61x and URI at 17.31x, so URI is the cheaper of the two on next year's expected earnings. A lower multiple is not automatically the better buy: a richer valuation can be justified by faster growth, and a lower one can reflect real risk. Weigh the multiple against how fast each business is compounding.
Should you own both CTOS and URI?
+
Because they share themes, owning both concentrates you in that theme. That can be intentional (a focused bet) or accidental (less diversification than it looks). Walnut can show your combined exposure across both, and whether adding either over-concentrates you, before you buy.
What are the risks of CTOS vs URI?
+
CTOS: CTOS is highly cyclical and capital-intensive, so a downturn in construction, utility or infrastructure spending would hit both rental demand and used-equipment resale values. The balance sheet carries roughly $1.65 billion of net debt near four times EBITDA, which makes the equity sensitive to interest rates and to any stumble in cash generation. The company has continued to report net losses even as EBITDA grows, so bottom-line profitability is not yet proven through the cycle. Concentration in electric utility end markets means a pullback in that single customer group would be outsized. Execution on the deleveraging plan is not guaranteed, and a broader industrial slowdown could push targets out. URI: URI is deeply cyclical, so a recession or a sustained slowdown in construction and industrial activity would lower utilization, pricing, and profits. The company carries substantial debt (well over $10 billion) used to fund fleet and acquisitions, so higher-for-longer interest rates raise borrowing costs and pressure interest coverage. Acquisition strategy adds integration risk, and a large planned deal (H&E Equipment Services) was ultimately terminated, showing that M&A outcomes are not guaranteed. Specialty and overall margins have faced inflationary cost and supply pressures at times. As a single industrial equity, it is also exposed to sentiment swings tied to rate expectations and the construction cycle.
