CTOS Q3 2026: Custom Truck One Source Bets on Grid Growth, Elevates Full-Year Guidance

October 26, 2026 • NYSE: CTOS

Custom Truck One Source, Inc. (CTOS) serves as the utility-scale weather vane for an infrastructure cycle that seems allergic to delays. In the third quarter, CTOS posted a revenue tallied near $495.2 million, up 2.7% from the year-ago period, and delivered a modest net income of $2.3 million alongside a robust Adjusted EBITDA print of $110.9 million. The company attributes ongoing strength in the transmission and distribution markets to grid modernization, electrification, and data-center growth—an equation that looks increasingly familiar to any industrial stock with a bearing on infrastructure capex.

Key metrics at a glance

Revenue: $495.2 million, up 2.7% YoY
Third-party STEM deliveries: backlog shift into Q4; STEM orders up 22% YoY
OEC on rent: $1.39 billion (record high)
Total OEC: $1.76 billion (record)
Fleet utilization: 81.5%
Adjusted EBITDA: $110.9 million, up 15.6% YoY
Net income: $2.3 million
SER segment Adjusted EBITDA: $121.9 million; SER revenue growth supported by stronger T&D trends
Net leverage: 3.70x (improved from late-2025 levels)

Guidance and capital plan signal a disciplined growth path

The company lifted its full-year 2026 outlook in several respects. CTOS raises its 2026 SER revenue guidance to $870 million to $890 million (from $850–$875 million) on sustained transmission and distribution momentum. It also increases CTOS Adjusted EBITDA guidance to $447.5 million to $460 million (from $437.5–$455 million). In addition, CTOS now expects 2026 net rental fleet investment to be $210 million to $230 million, aiming to capture visible, high-return transmission rental demand. Management notes that levered free cash flow for 2026 is now expected to be slightly positive, with the earnings benefit of the incremental fleet skewed toward 2027.

These moves underscore a capital plan focused on expanding the rented fleet where demand is strongest, while moderating the pace of leverage as asset utilization improves. The company also highlights that STEM orders grew 22% year over year, with some third-party deliveries shifted out of Q3 and into Q4, a reminder that timing is still a factor in reporting metrics that investors care about.

Notes on EPS, consensus, and earnings surprises

The filing uses net income and Adjusted EBITDA rather than a per-share EPS figure. As a result, there is no disclosed EPS or EPS consensus in the press materials. In practice, investors will eventually translate CTOS’s quarterly results into EPS by applying the company’s share count and potential dilutive instruments. An earnings surprise would require CTOS’s GAAP or adjusted EPS to land above (or below) the consensus estimate among analysts. Until CTOS reports a formal EPS figure or a stated consensus, the market will view the headline numbers through the prism of revenue trajectory, EBITDA resilience, and cash-flow implications—factors that have immediate bearing on the stock’s multiple and the sector’s risk premium.

Operational detail: what powers the move and what it portends

The core narrative centers on grid modernization and electrification—long-standing themes in infrastructure equity that CTOS ties directly to demand for qualified equipment fleets. The record OEC on rent and a high fleet utilization rate signal a healthy utilization backdrop, while a lower net leverage ratio suggests the company is managing the balance sheet as capex scales with the top line. The SER segment’s EBITDA strength points to a favorable mix of high-margin, long-lived rental activities alongside ongoing demand in transmission equipment, while STEM exposure serves as a reminder that project timing matters for revenue cadence.

From a sector perspective, CTOS’s guidance raises the bar for peers tied to T&D, data centers, and broad electrification megatrends. If a handful of peers can translate increased order backlogs into sustained revenue visibility and EBITDA expansion, the broader infrastructure equipment space could see multiple expansion as investors price in a more robust capex cycle rather than a one-quarter sprint.

Takeaways for peers and investors

Revenue forecast robustness: CTOS’s raised revenue trajectory suggests management’s view of a durable demand runway in T&D and related markets.
EBITDA discipline: The move to higher Adjusted EBITDA targets signals a preference for operating leverage and margin discipline even as the fleet grows.
Capital allocation guardrails: Incremental fleet investment paired with a positive levered free cash flow stance indicates a strategic balance between growth and liquidity risk—an attractive posture in a capital-intensive space.
Risk factors: STEM deliveries timing remains a near-term swing factor; any further delays or project deferrals could temper near-term revenue cadence despite long-run tailwinds.
EPS and earnings narrative: With EPS data not disclosed, the market will watch how CTOS translates EBITDA growth into per-share results and whether management provides a credible EPS path against consensus in upcoming quarters.

Industry outlook and forward-looking considerations

The quarter reinforces a broader narrative: a currency for infrastructure demand beyond traditional cyclicality. Grid modernization, transmission expansion, and electrification are less a temporary flare and more a structural upgrade cycle. CTOS’s results align with peers that benefit from steady if not spectacular capex flows in utilities, data-center buildouts, and related infrastructure services. For sector peers, the message is clear: demonstrate cadence in fleet utilization, convert order backlogs into revenue with predictable timing, and manage leverage as capex ramps up.

Conclusion

CTOS’s Q3 performance and revised full-year guidance point to a company comfortably riding a secular growth curve in infrastructure and grid modernization. The combination of record OEC, improving leverage, and a bigger footprint for the rental fleet supports a constructive view for CTOS’s trajectory into 2027, even as near-term timing of STEM deliveries and project phasing remains a wildcard. For readers tracking EPS, earnings surprises, and revenue forecasts, CTOS offers a case study in how a capital-efficient equipment rental model can translate macro secular demand into higher operating cadence—and perhaps, a steadier earnings narrative than the quarterly drumbeat might otherwise suggest.
