Custom Truck One Source (CTOS) Q4 2025 earnings review
Strong Rentals Overcome Equipment Sales Slump to Drive Record EBITDA
Custom Truck One Source posted record Q4 revenue of $528.2 million, though YoY growth decelerated sharply to 1.4% due to a sudden slump in equipment sales. Despite the top-line slowdown, Adjusted EBITDA surged 18.4% to $120.7 million, powered by a booming Equipment Rental Solutions (ERS) segment that achieved near three-year high utilization. While Net Income declined YoY, this was entirely due to a $23.5 million one-time real estate gain in the prior year; core operations improved. Management successfully reduced inventory by over $100 million in Q4, aiding deleveraging efforts, and issued confident FY26 guidance projecting 3-9% revenue growth and continued margin expansion.
🐂 Bull Case
ERS is operating at peak efficiency, with fleet utilization hitting 83.6% and average OEC on rent jumping 13.7%. This highly profitable segment is carrying the company's margin expansion.
Management's promise to unwind strategic inventory buildup is bearing fruit. A >$100 million inventory reduction in Q4 sets up robust free cash flow generation and continued deleveraging in 2026.
🐻 Bear Case
Truck and Equipment Sales (TES) revenue flipped to a 7.7% contraction in Q4. Management cited tariff pull-forwards and year-end deferrals, but gross margins also compressed 13.1%, indicating competitive pricing pressure.
Despite progress, net leverage stands at 4.3x. Achieving the long-term target of <3.0x by 2027 will require sustained flawless execution and limits capital allocation flexibility in the near term.
⚖️ Verdict: 🟢
Bullish. The 1.4% revenue growth masks a highly favorable mix shift. The core rental business is exceptionally strong, and the company is executing perfectly on its working capital and deleveraging mandates. The TES slump appears to be a timing issue rather than a structural failure.
Key Themes
Exceptional Fleet Utilization Driving Rental Growth
The Equipment Rental Solutions (ERS) segment is accelerating dramatically. Fleet utilization hit 83.6% in Q4—the highest level in nearly three years—up from 78.9% a year ago. This efficiency, combined with a 13.7% increase in average OEC on rent, drove a 20% YoY increase in segment revenue and a 19.1% jump in Adjusted Gross Profit. The strategic shift to emphasize the rental fleet over the last year is paying massive dividends.
TES Sales Reversing Under Pressure
After a strong Q2 and stable Q3, Truck and Equipment Sales (TES) suddenly reversed, declining 7.7% YoY to $284.0 million in Q4. Management attributed the drop to mid-year capital expenditure pull-forwards (due to tariff fears) and year-end delivery deferrals into 2026. However, TES Gross Profit dropped an even steeper 13.1% YoY, highlighting continued pricing pressures on truck sales. Order backlog did improve sequentially by $30 million to $335.3M, providing some comfort for early 2026.
Inventory Reduction Execution
CTOS successfully executed on its promise to unwind the massive inventory buildup accumulated over the past two years to mitigate supply chain and tariff risks. Inventory was slashed by over $100 million sequentially in Q4 (ending at $930.9 million). This working capital release directly fed into lower floor plan interest expenses and allowed for continued debt paydown.
Major Segment Restructuring for 2026
Beginning Q1 2026, CTOS is abandoning its three-segment structure (ERS, TES, APS) in favor of two reporting segments: Specialty Equipment Rentals (SER) and Specialty Truck Equipment and Manufacturing (STEM). The aftermarket parts (APS) business will be split between these two. Management believes this will better align external reporting with internal capital allocation and highlight the distinct margin and capital intensity profiles of the rental versus manufacturing arms.
Aftermarket Parts and Services (APS) Lagging
While overshadowed by the larger segments, APS revenue decelerated sharply, dropping 8.5% YoY in Q4 to $37.1 million. The company cited softer demand across parts, tools, and accessories, alongside lower service activity. While it remains a high-margin segment (27.0% gross margin), its contraction acts as a drag on overall growth.
Secular Tailwinds in Transmission & Distribution
The macro thesis remains intact. Management continues to cite strong secular tailwinds from data center investments, broad electrification, and vital utility grid upgrades. This infrastructure spending boom is the primary catalyst keeping ERS utilization at record highs.
Other KPIs
Stable but elevated. The ratio improved steadily throughout the year (4.8x in Q1 -> 4.66x in Q2 -> 4.53x in Q3 -> 4.31x in Q4). Management expects it to be 'meaningfully below four times' by the end of 2026, maintaining the ultimate target of below 3.0x by 2027.
Reversing. Despite record revenue and EBITDA, the company posted a net loss for the year, wider than 2024's $(28.7) million. The divergence is driven heavily by high interest expenses ($157.6 million in FY25) tied to the $1.66 billion debt load, underscoring the urgency of the deleveraging strategy.
Guidance
Accelerating. The midpoint implies ~6% YoY growth, a significant acceleration from the 1.4% growth seen in Q4. It suggests management views the Q4 TES deferrals as a temporary timing issue rather than a demand cliff.
Accelerating. Implies 7% to 13% growth YoY. Outpacing revenue growth, this indicates expectations for continued margin expansion, likely driven by maintaining high utilization rates in the ERS segment and lower floor plan interest as inventory shrinks.
Decelerating. A meaningful reduction from the >$250 million invested in 2025. Because the average fleet age is young (2.9 years), the company can afford to slow capital expenditures, which directly supports the goal of generating >$50 million in levered free cash flow.
Accelerating. Represents healthy mid-single to high-single digit growth on top of a very strong 2025, riding the momentum of record utilization and long-term utility end-market strength.
Key Questions
TES Deferrals vs. Demand Softness
You noted that TES sales fell 7.7% due to mid-year pull-forwards and year-end customer deferrals. Are these deferred orders definitively locked in for Q1 2026, or is there a risk of outright cancellation if macroeconomic caution persists?
Margin Profile of the New 'STEM' Segment
With the upcoming combination of TES and parts of APS into the new STEM segment, how should we think about the blended margin profile, especially given the pricing pressures currently acting on the truck sales side?
Leverage Target Realism
You reaffirmed the target of reaching <3.0x net leverage in 2027. Given you ended 2025 at 4.3x, and guidance suggests >$50 million in levered free cash flow for 2026, what is the mathematical bridge to shed a full turn of leverage in the next 24 months?
