Is CTOS a Buy? What to Consider in 2026
Last updated July 2026
Short answer
The bull case for Custom Truck One Source rents and sells specialized work trucks and equipment (CTOS) rests on Grid modernization and utility T&D demand: The core demand driver is aging US electric grid infrastructure, electrification and federal infrastructure funding. Revenue (2025) is ~$1.94B. If you believe that thesis holds, the real questions become position sizing and overlap, not timing. The main risk to that view: 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. Whether CTOS is a buy comes down to whether you believe the thesis. This is informational, not a recommendation, and Walnut is not an investment adviser.
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. The investment picture is a leveraged bet on that infrastructure cycle. Fleet utilization and rental revenue rebounded strongly through 2025 and into 2026, adjusted EBITDA is growing, and management is guiding for higher profitability, but the company still carries roughly $1.65 billion of net debt at around four times EBITDA and has been posting net losses at the bottom line. The bull case is deleveraging plus durable utility demand; the bear case is a capital-heavy, cyclical model where a slowdown in equipment demand or higher-for-longer interest rates squeezes both fleet economics and the balance sheet.
What's the case for buying CTOS?
1. Grid modernization and utility T&D demand
The core demand driver is aging US electric grid infrastructure, electrification and federal infrastructure funding. Utility transmission and distribution work requires exactly the specialty trucks CTOS rents and sells, which gives it a long runway if utility capex stays elevated. This end-market concentration is both the growth engine and the key dependency.
2. Rental fleet utilization and mix
Higher fleet utilization, which reached the low-to-mid 80s percent in recent quarters, drives operating leverage because the fleet is a mostly fixed asset base. Growing the higher-margin rental segment and selling used equipment out of the fleet at good prices are the main levers on returns. Rental revenue grew double digits in 2025.
3. Deleveraging and free cash flow
Management has committed to bringing net leverage below four times by the end of 2026 and toward roughly three times in 2027 by generating levered free cash flow and reining in net fleet capex. Successful deleveraging would materially reduce interest expense and equity risk. Progress here is arguably the single most important swing factor for the stock.
4. Record sales volumes across TES
The Truck and Equipment Sales segment delivered record annual revenue around $1.1 billion in 2025, showing that demand extends beyond rental into outright purchases by customers. A broad platform across rental, sales, parts and service can smooth some cyclicality and capture the full equipment lifecycle.
What are the risks to 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.
How is CTOS valued? (as of July 2026)
Snapshot for CTOS as of July 2026, sourced from Yahoo Finance and may be delayed. Valuation figures move with price and earnings; verify the current numbers with your broker before deciding.
- Revenue (2025): ~$1.94B
- Revenue (Q1 2026): ~$462M (+9%)
- Adjusted EBITDA (LTM): ~$408M
- 2026 Adj. EBITDA guidance: ~$415M-440M
- Net debt / leverage: ~$1.65B, ~4x
- Market cap: ~$2.0-2.3B
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.
How do you decide if CTOS is a buy?
Rather than asking whether CTOS is a buy in the abstract, it tends to help to answer four questions:
- Thesis: do you believe the case above, and is it still true today?
- Time horizon: a single stock can be volatile, so a longer horizon absorbs more of the swings.
- Position sizing: a thesis can be right and the sizing still wrong; decide how much of your portfolio one name should be.
- Overlap: check whether you already hold CTOS indirectly through an index or sector ETF before adding more.
