KANSAS CITY, Mo. July 30, 2025 – (BUSINESS WIRE) – Custom Truck One Source, Inc. (NYSE: CTOS), a leading provider of specialty equipment to the electric utility, telecom, rail, forestry, waste management and other infrastructure-related end markets, today reported financial results for the three and six months ended June 30, 2025.

•Total revenue of $511.5 million, an increase of $88.5 million, or 20.9%, compared to the second quarter of 2024

•Gross profit of $102.5 million, an increase of $13.3 million, or 14.9%, compared to the second quarter of 2024

•Adjusted Gross Profit of $156.5 million, an increase of $22.7 million, or 17.0%, compared to the second quarter of 2024

•Net loss of $28.4 million, an increase of $3.9 million, or 15.9%, compared to the second quarter of 2024

•Adjusted EBITDA of $93.4 million, an increase of $13.4 million, or 16.7%, compared to the second quarter of 2024

•Increased Average OEC on rent by $162.5 million, or 15.6%, compared to the second quarter of 2024

“In the second quarter, we achieved strong year-over-year revenue growth of 21% and adjusted EBITDA growth of 17%, driven by growth in every segment. We continue to see steady performance in our core T&D market, carrying forward our solid first quarter performance into the second quarter. This resulted in significant year-over-year increases in rental revenue and rental asset sales within our ERS segment of 17% and 40%, respectively. For the quarter, our rental fleet saw average utilization of just under 78%, a significant improvement versus the same period last year and in line with our expectations. Average OEC on rent for the second quarter was more than $160 million higher than the same period last year and we ended the quarter with total OEC of $1.56 billion. This was up sequentially from the end of last quarter and the highest in our history, which we anticipate will support our expected growth within ERS for the remainder of 2025 and into 2026,” said Ryan McMonagle, Chief Executive Officer of CTOS. “TES sales were up more than 22% year-over-year and achieved the second highest quarter of sales ever. Sustained, robust demand for vocational vehicles across our end markets, particularly intra-quarter demand from local and regional customers, continues to drive the performance within the TES segment. Signed orders in the quarter were up 30% on a year-over-year basis and we continue to believe that this current strong pace of customer orders and our existing TES backlog position us well to achieve the growth we expect in the segment this year. Given current market conditions and ongoing customer conversations regarding demand for the second half of 2025, we continue to believe Custom Truck is well-positioned to benefit from secular tailwinds driven by data center investments, electrification, and utility grid upgrades. As a result, we are reaffirming our 2025 guidance,” McMonagle added.

Our results are reported for our three segments: Equipment Rental Solutions (“ERS”), Truck and Equipment Sales (“TES”) and Aftermarket Parts and Services (“APS”). ERS encompasses our core rental business, inclusive of sales of used rental equipment to our customers. TES encompasses our specialized truck and equipment production and new equipment sales activities. APS encompasses sales and rentals of parts, tools, and other supplies to our customers, as well as our aftermarket repair service operations.

(a) Ending OEC — Ending original equipment cost (“OEC”) is the original equipment cost of units at the end of the measurement period.

(b) Average OEC on rent — Average OEC on rent is calculated as the weighted-average OEC on rent during the stated period.

(c) Fleet utilization — total number of days the rental equipment was rented during a specified period of time divided by the total number of days available during the same period and weighted based on OEC.

(d) OEC on rent yield (“ORY”) — a measure of return realized by our rental fleet during a period. ORY is calculated as rental revenue (excluding freight recovery and ancillary fees) during the stated period divided by the Average OEC on rent for the same period. For periods of less than 12 months, the ORY is adjusted to an annualized basis.

(e) Sales order backlog — purchase orders received for customized and stock equipment. Sales order backlog should not be considered an accurate measure of future net sales.

Second quarter 2025 consolidated rental revenue increased 17.3% compared to the second quarter of 2024 due to higher average OEC on rent and fleet utilization. Consolidated equipment sales increased 24.7% compared to the second quarter of 2024, primarily driven by an increase in new equipment sales. Consolidated parts sales and service revenue remained flat year-over-year.

The 16.9% increase in ERS segment rental revenue in the second quarter of 2025 compared to the second quarter of 2024 was the result of improved fleet utilization (which increased to 77.6% compared to 71.7%) driven by increased rental volume, with average OEC on rent increasing by 16% year-over-year. Compared to the second quarter of 2024, rental equipment sales increased 39.9% in the second quarter of 2025. ERS gross profit and adjusted gross profit increased 16.8% and 19.7%, respectively, in the second quarter of 2025 compared to the second quarter of 2024.

Revenue in our TES segment increased 22.4% in the second quarter of 2025 compared to the second quarter of 2024 driven by robust demand for vocational vehicles across our end markets, particularly intra-quarter demand from local and regional customers. Gross profit increased by 11.1% in the second quarter of 2025 compared to the second quarter of 2024. While our TES backlog was down 9% compared to the fourth quarter of 2024, it remains within our expected range of four to six months.

APS segment revenue in the second quarter of 2025 increased by 2.6% compared to the second quarter of 2024 due to an increase in rental revenue. Gross profit margin increased due to the increase in rental revenue.

The increase in net loss in the second quarter of 2025 compared to the second quarter of 2024, was primarily due to higher income tax expense. Income tax expense for the six-month period ended June 30, 2025 was $9.8 million. Income tax expense for the quarterly ended June 30, 2025 reflects an adjustment for the change to our estimated annual effective tax rate resulting from changes in expected taxable income in differing taxing jurisdictions. Despite this change, we expect annual cash taxes to be paid to remain at levels consistent with previous years.

Adjusted EBITDA for the second quarter of 2025 was $93.4 million, a 16.7% increase compared to the second quarter of 2024, which was largely driven by increased gross profit and lower interest expense on variable-rate floor plan liabilities from lower inventory levels.

As of June 30, 2025, cash and cash equivalents was $5.3 million, Total Debt outstanding was $1,630.7 million, Net Debt was $1,625.4 million and Net Leverage Ratio was 4.66x. Availability under the senior secured credit facility was $275.7 million as of June 30, 2025, and based on our borrowing base, we have an additional $231.1 million of suppressed availability that we can potentially utilize by upsizing our existing facility.

We are reaffirming our full-year revenue and Adjusted EBITDA1, 4 guidance for 2025 at this time. With record new sales in the quarter and average OEC on rent up more than $160 million, or 16%, in the second fiscal quarter compared to the same period last year, we continue to expect 2025 to be a year of double-digit revenue and adjusted EBITDA growth. The TES segment continues to benefit from a good macro demand environment as well as our strong relationships with our key customers, and chassis and attachment suppliers. While our backlog was down in the quarter, our intra-quarter order flow remains quite strong, particularly among local and regional customers, with signed orders from this portion of our customer base up more than 45% on a year-over-year basis in the quarter, driving overall year-over-year signed order growth of just under 35%. After the volatility in our ERS segment rental markets in 2024, primarily in the transmission and distribution utility market, we have experienced strong demand in our rental business over the past three fiscal quarters. We continue to focus on further penetrating the vocational rental market and believe the ERS outlook from our rental customers for long-term demand and growth will be strong. Given the strong demand environment, we expect to grow our rental fleet (based on net OEC) by at least mid-single digits by the end of the year. Regarding TES, supply chain improvements, healthy, but improved inventory levels exiting 2024, normalized backlog levels, and strong order flow will continue to allow us to generate double-digit revenue growth in 2025. Further, despite a tactical investment in inventory during the first half of the year to mitigate the impact of new tariffs, we expect to make progress on unwinding our significant strategic investment in inventory levels over the last two years by the end of the year. As a result, we expect to generate meaningful free cash flow in 2025, setting a target to generate more than $50 million of levered free cash flow2, 4 and deliver a meaningful reduction in our net leverage ratio3, 4 by the end of the fiscal year.

In our press release and schedules, and on the related conference call, we report certain financial measures that are not required by, or presented in accordance with, United States generally accepted accounting principles (“GAAP”). We utilize these financial measures to manage our business on a day-to-day basis and some of these measures are commonly used in our industry to evaluate performance by excluding items considered to be non-recurring. We believe these non-GAAP measures provide investors expanded insight to assess performance, in addition to the standard GAAP-based financial measures. The press release schedules reconcile the most directly comparable GAAP measure to each non-GAAP measure that we refer to. Although management evaluates and presents these non-GAAP measures for the reasons described herein, please be aware that these non-GAAP measures have limitations and should not be considered in isolation or as a substitute for revenue, operating income/loss, net income/loss, earnings/loss per share or any other comparable measure prescribed by GAAP. In addition, we may calculate and/or present these non-GAAP financial measures differently than measures with the same or similar names that other companies report, and as a result, the non-GAAP measures we report may not be comparable to those reported by others.

Adjusted EBITDA. Adjusted EBITDA is a non-GAAP performance measure that we use to monitor our results of operations, to measure performance against debt covenants and performance relative to competitors. We believe Adjusted EBITDA is a useful performance measure because it allows for an effective evaluation of operating performance, without regard to financing methods or capital structures. We exclude the items identified in the reconciliations of net income (loss) to Adjusted EBITDA because these amounts are either non-recurring or can vary substantially within the industry depending upon accounting methods and book values of assets, including the method by which the assets were acquired, and capital structures. Adjusted EBITDA should not be considered as an alternative to, or more meaningful than, net income (loss) determined in accordance with GAAP. Certain items excluded from Adjusted EBITDA are significant components in understanding and assessing a company’s financial performance, such as a company’s cost of capital and tax structure, as well as the historical costs of depreciable assets, none of which are reflected in Adjusted EBITDA. Our presentation of Adjusted EBITDA should not be construed as an indication that results will be unaffected by the items excluded from Adjusted EBITDA. Our computation of Adjusted EBITDA may not be identical to other similarly titled measures of other companies.

We define Adjusted EBITDA as net income or loss before interest expense, income taxes, depreciation and amortization, share-based compensation, and other items that we do not view as indicative of ongoing performance. Our Adjusted EBITDA includes an adjustment to exclude the effects of purchase accounting adjustments when calculating the cost of inventory and used equipment sold. When inventory or equipment is purchased in connection with a business combination, the assets are revalued to their current fair values for accounting purposes. The consideration transferred (i.e., the purchase price) in a business combination is allocated to the fair values of the assets as of the acquisition date, with amortization or depreciation recorded thereafter following applicable accounting policies; however, this may not be indicative of the actual cost to acquire inventory or new equipment that is added to product inventory or the rental fleets apart from a business acquisition. We also include an adjustment to remove the impact of accounting for certain of our rental contracts with customers containing a rental purchase option that are accounted for under GAAP as a sales-type lease. We include this adjustment because we believe continuing to reflect the transactions as an operating lease better reflects the economics of the transactions given our large portfolio of rental contracts. These, and other, adjustments to GAAP net income or loss that are applied to derive Adjusted EBITDA are specified by our senior secured credit agreement and the indenture of our senior secured notes.

Adjusted Gross Profit. We present total gross profit excluding rental equipment depreciation (“Adjusted Gross Profit”) as a non-GAAP financial performance measure. This measure differs from the GAAP definition of gross profit, as we do not include the impact of depreciation expense, which represents non-cash expense. We use this measure to evaluate operating margins and the effectiveness of the cost of our rental fleet.

Net Debt. We present the non-GAAP financial measure “Net Debt,” which is total debt (the most comparable GAAP measure, calculated as current and long-term debt, excluding deferred financing fees, plus current and long-term finance lease obligations) minus cash and cash equivalents. We believe this non-GAAP measure is useful to investors to evaluate our financial position.

Net Leverage Ratio. Net leverage ratio is a non-GAAP performance measure used by management and we believe it provides useful information to investors because it is an important measure to evaluate our debt levels and progress toward leverage targets, which is consistent with the manner our lenders and management use this measure. We define net leverage ratio as net debt divided by Adjusted EBITDA for the previous twelve-month period (“last twelve months,” or “LTM”).

Adjusted EBITDA is defined as net income (loss), as adjusted for provision for income taxes, interest expense, net, depreciation of rental equipment and non-rental depreciation and amortization, and further adjusted for the impact of the fair value mark-up of acquired rental fleet, business acquisition and merger-related costs, including integration, the impact of accounting for certain of our rental contracts with customers that are accounted for under GAAP as sales-type lease and stock compensation expense. This non-GAAP measure is subject to certain limitations.

(1)    Represents the non-cash impact of purchase accounting, net of accumulated depreciation, on the cost of equipment and inventory sold. The equipment and inventory acquired received a purchase accounting step-up in basis, which is a non-cash adjustment to the equipment cost pursuant to our ABL Credit Agreement and Indenture.

(2)    Represents transaction and other costs related to acquisitions of businesses; costs associated with closed operations; costs associated with restructuring and business optimization activities (inclusive of systems establishment costs); employee retention and/or severance costs; costs related to start-up/pre-openings and openings of locations; reconfiguration or consolidation of facilities or equipment conversion costs. These adjustments are presented as adjustments to net income (loss) pursuant to our ABL Credit Agreement and Indenture.

(3)    Represents the impact of sales-type lease accounting for certain leases containing rental purchase options (or “RPOs”), as the application of sales-type lease accounting is not deemed to be representative of the ongoing cash flows of the underlying rental contracts. The adjustments are made pursuant to our ABL Credit Agreement and Indenture. The components of this adjustment are presented in the table below:

(4) Represents non-cash share-based compensation expense associated with the issuance of restricted stock units.

(5) Represents the charge to earnings for the change in fair value of the liability for warrants. On July 31, 2024, all of the Company’s stock purchase warrants expired and were unexercised.
