Custom Truck One Source (CTOS) Q2 2026 Earnings Call Transcript

Custom Truck One Source reported Q2 revenue of $563.4M (+10.2% YoY) and adjusted EBITDA of $116.8M (+25.0% YoY), with SER segment utilization rising 400 bps to 81.6% and on-rent yield up 80 bps to 39.4%. Management raised FY2026 guidance to $2.1B–$2.2B revenue and $437.5M–$455M adjusted EBITDA (+14% to +19% YoY) and expects levered free cash flow to exceed $50M while reducing net leverage from 4.02x to 3.85x. The main headwind is higher customer costs tied to EPA 2027 NOx emission standards, but the company says chassis “prebuy” and OEM relationships should position it well, calling transmission demand early innings of a potential “once-in-a-generation” super cycle.

Analysis

CTOS is one of the cleaner ways to express the grid-capex cycle because its upside is coming from utilization and pricing, not just top-line volume. The key second-order effect is that transmission work tends to be longer-duration and more equipment-intensive than distribution, so a modest mix shift can keep utilization elevated even if quoted volumes normalize. That supports margin durability into the next few quarters and creates operating leverage that the market may still be underappreciating.

The more important near-term read-through is not CTOS itself but the supply chain: chassis, powertrain, and engine vendors should get a prebuy tailwind into 2027, while smaller rental yards with older fleets face a step-up in compliance capex and pricing pressure. Cummins (CMI) looks like the clearest public beneficiary from the engine transition, while broad rental peers with less T&D exposure could lag if investors rotate toward names tied to regulated infrastructure rather than generic construction demand. If federal funding finally converts into executed projects, the lag is months to quarters, so the next data point to watch is quote-to-book, not commentary.

The contrarian risk is that some of this is pull-forward: the market may be extrapolating a super-cycle while ignoring that 2H order conversion can flatten once customers have prebuys in hand. That makes the next 1-3 months critical: if backlog rebuilds and utilization stays in the low-80s, the rerating can continue; if backlog stalls or leverage stops improving, the stock can quickly shift back to a balance-sheet story. The thesis is falsified if utilization slips below the high-70s, backlog remains below the mid-$300m area next quarter, or management stops showing progress toward sub-4x leverage by year-end.

Key Decisions for Investors

• Go long CTOS on post-earnings consolidation for a 1-3 month trade; thesis is that the market will eventually pay for utilization-driven EBITDA expansion and improving free cash flow, with downside limited unless backlog or utilization rolls over.
• Pair trade: long CTOS / short URI over the next 1-3 months to isolate T&D-specific demand from broader rental beta; this works if infrastructure demand keeps compounding while general equipment rental remains more cyclical.
• Add CMI as a 6-18 month beneficiary of the emissions-driven chassis/engine transition, especially if X10 production ramps as expected; the setup is more of a supply-chain torque play than a direct earnings catalyst.
• Avoid chasing CTOS if the stock gaps hard on the print; wait for a pullback or confirm that Q3 quote conversion and backlog re-acceleration are real before sizing up.
• Set an alert to reduce exposure if CTOS utilization drops below 78% or net leverage stalls above 4.0x, because that would imply the narrative is moving from structural growth to temporary pull-forward.
