Why Was Custom Truck One Source Stock Up on Aug 5, 2026?
Record revenue and a guidance raise driven by utility grid upgrades and data-center-linked electrification demand, seen from the equipment-rental side.
- Custom Truck One Source posted record Q2 2026 revenue of $563.45 million, up 10.2% year over year, with adjusted EBITDA up 25.0% to $116.8 million and net income of $10.4 million versus a loss a year earlier. Shares rose 7.244%.
- The company raised full-year 2026 revenue guidance to $2.100-2.197 billion from $2.002-2.119 billion, and adjusted EBITDA guidance to $437.5-455 million, on the back of record first-half performance and fleet utilization of 81.6%.
- Management named the specific demand driver: sustained strength in Transmission & Distribution (T&D) utility markets, with the company explicitly positioned to benefit from data-center investment, electrification, and utility grid upgrades — the same infrastructure wave other names are riding, but from the equipment-rental side rather than construction or manufacturing.

Custom Truck One Source posted record Q2 2026 revenue of $563.45 million, up 10.2% year over year. Adjusted EBITDA rose 25.0% to $116.8 million, and the company swung to net income of $10.4 million from a loss in the same quarter a year earlier. Shares rose 7.244% on the day.
A different vantage point on the same infrastructure wave
Custom Truck rents and sells the specialized trucks — bucket trucks, digger derricks, and related heavy equipment — that utility crews use to build and maintain transmission and distribution lines. Management named sustained strength in Transmission & Distribution (T&D) markets as the primary driver of the quarter, and said the company remains well-positioned to benefit from data-center investment, electrification, and utility grid upgrades. That is the same infrastructure buildout theme showing up elsewhere this earnings season, but from the equipment side of the work: when utilities and grid operators ramp up construction crews to handle rising power demand, Custom Truck's rental fleet is what those crews show up in.
Utilization, not just volume, drove the beat
Fleet utilization reached 81.6%, and the guidance raise — to $2.100-2.197 billion revenue and $437.5-455 million adjusted EBITDA — came specifically on the back of record first-half performance rather than a single strong quarter. A rental-fleet business raising full-year EBITDA guidance after a utilization improvement is a durable kind of beat: it means more of the existing fleet is generating revenue, not just that more trucks were bought and sold in the quarter.
What to watch
Fleet utilization in the next two quarters is the number that shows whether 81.6% is a new sustained operating level for the business or a peak tied to a temporary surge in utility construction activity.
