What drove it
- Record demand across core transmission and distribution markets.
- Rental revenue increased through higher rental volume, improved fleet utilization, increased average OEC on rent, and improved OEC on rent yield.
- SER equipment sales increased 14.1% because of increased buyout activity of rental contracts with purchase options.
- STEM intercompany sales increased to support increased rental activity.
- Lower floor plan interest expense resulted from lower inventory levels.
- Transmission demand, electrification, data center-driven load growth, and infrastructure spending were identified as secular trends supporting demand.
Concerns
- More than $20.0 million of third-party STEM deliveries shifted into the fourth quarter following a vendor recall and unusual hailstorm damage to finished vehicle inventory at the Kansas City location.
- Third-party new equipment sales declined 5.5% because of lower third-party unit sales volume as production was prioritized for rental-fleet investment.
- Sales order backlog of approximately 3.8 months of LTM third-party new sales was modestly below the targeted range of four to six months.
- Levered free cash flow for 2026 is now expected to be slightly positive, compared to prior guidance of more than $50 million, reflecting higher net rental fleet investment and working capital associated with growth.
- Total debt outstanding was $1,666.0 million and net debt was $1,651.5 million as of September 30, 2026.
What to watch
- Completion of more than $20 million of third-party deliveries expected in the fourth quarter.
- Whether OEC on rent and utilization, which surpassed $1.5 billion and 84%, respectively, in October, continue to support SER growth.
- Conversion of the $342 million sales order backlog and fourth-quarter third-party new-sales growth expected at a mid-to-high-teens rate year-over-year.
- Execution of approximately $400 million to $430 million of gross rental fleet investment, with the larger revenue and earnings contribution expected in 2027.
- Progress toward a net leverage ratio meaningfully below four times at fiscal year-end 2026 and below three times in 2027.

Analysis
Custom Truck One Source reported third-quarter revenue of $495,224 (in $000s), up 2.7% from $482,058 (in $000s), while rental revenue rose 20.1% to $152,696 (in $000s). Gross Profit increased 12.4% to $113,280 (in $000s), and Adjusted EBITDA increased 15.6% to $110,942 (in $000s). Net Income was $2,305 (in $000s), compared with a Net Loss of $(5,756) (in $000s) in the prior-year quarter. The company cited higher operating income from rental-revenue growth and lower interest expense as the primary drivers of the earnings improvement.
SER was the principal operating contributor. Average OEC on rent reached $1,394,661 (in $000s), fleet utilization was 81.5%, and OEC on rent yield was 39.4%. Ending OEC was a record $1,764,963 (in $000s), up $143.0 million year-over-year. SER Segment Adjusted EBITDA was $121,856 (in $000s), compared with $99,465 (in $000s), while the segment Adjusted EBITDA margin expanded to 54.6% from 52.4%. Management attributed rental growth to increased volume, improved utilization, a 10.5% increase in average OEC on rent, and improved yield.
STEM results reflected a shift in mix toward intercompany activity supporting rental-fleet growth. Total Segment Revenue was $442,158 (in $000s), up 8% year-over-year, while STEM Segment Adjusted EBITDA was $36,636 (in $000s), compared with $17,664 (in $000s). Third-party new equipment sales declined 5.5% amid lower unit volume, as CTOS prioritized production for its rental fleet. A vendor recall and hailstorm damage delayed more than $20.0 million of third-party deliveries into the fourth quarter, though management stated the units remain in backlog and are expected to ship in the fourth quarter.
Cash generation funded substantial fleet investment. Net cash flow from operating activities was $231,660 (in $000s) for the first nine months, while purchases of rental equipment were $(352,578) (in $000s). Cash and cash equivalents were $14,564 (in $000s), total debt outstanding was $1,666.0 million, and net debt was $1,651.5 million at September 30, 2026. Net leverage declined to 3.70 from 4.53 at the end of the third quarter of 2025, despite the year-over-year increase in fleet OEC.
The company raised its full-year 2026 revenue outlook to $2,100 million to $2,200 million and Adjusted EBITDA outlook to $447.5 million to $460 million. SER revenue guidance increased to $870 million to $890 million from $850 million to $875 million. CTOS also increased expected net rental fleet investment to approximately $210 million to $230 million from $170 million to $200 million. The increased investment changes expected 2026 levered free cash flow to slightly positive from more than $50 million, with management positioning the incremental fleet for a larger earnings contribution in 2027.
Management, verbatim
In the third quarter, record demand across our core T&D markets drove 16% year-over-year Adjusted EBITDA growth and 24% growth year to date, and we are raising our full-year Adjusted EBITDA outlook for the third time this year.
Ryan McMonagle, Chief Executive Officer of CTOS
In STEM, orders grew 22% year-over-year and backlog reached $342 million, and the third-party deliveries that shifted out of the quarter are scheduled to ship in the fourth quarter.
Ryan McMonagle, Chief Executive Officer of CTOS
Third quarter results reflect what we believe are the early stages of what could be a once-in-a-generation transmission demand super-cycle in our utility end markets.
