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 months ended March 31, 2026.

CTOS First-Quarter Highlights

Record first quarter revenue of $461.6 million, an increase of $39.4 million, or 9.3%, compared to the first quarter of 2025
Increased Average OEC on rent by $141.4 million, or 11.8%, compared to the first quarter of 2025
Gross profit of $103.1 million, an increase of $17.5 million, or 20.5%, compared to the first quarter of 2025
Adjusted Gross Profit of $159.3 million, an increase of $23.6 million, or 17.4%, compared to the first quarter of 2025
Net loss of $4.1 million, an improvement of $13.7 million, or 76.9%, compared to the first quarter of 2025
Adjusted EBITDA of $98.0 million, an increase of $24.6 million, or 33.4%, compared to the first quarter of 2025
Given strong conditions in the transmission and distribution ("T&D") end markets, increasing 2026 full year Adjusted EBITDA¹ guidance range from $410M - $435M to $415M - $440M

"In the first quarter, we achieved record first-quarter revenue and delivered substantial year-over-year growth in revenue and Adjusted EBITDA of 9% and 33%, respectively. The sustained performance in our core T&D markets continues to be the primary driver of performance within our SER segment and for the Company as a whole. For the quarter, our rental fleet achieved average utilization of 81.4%, up 370 basis points versus the first quarter of last year. We ended the quarter with total OEC of $1.66 billion, the highest in our history, which should support our expected growth within SER in 2026," said Ryan McMonagle, Chief Executive Officer of CTOS. "Our STEM segment also had a strong quarter, delivering revenue of $268 million, which excludes $95 million of sales to our SER segment. Our strong performance in the quarter allowed us to make substantial progress in reducing our net leverage, down almost 30 basis points versus the end of the previous quarter. We continue to be optimistic about the remainder of 2026, as CTOS remains well-positioned to benefit from secular tailwinds driven by data center investments, electrification, utility grid upgrades and infrastructure investment. For 2026, we remain focused on Adjusted EBITDA growth, working capital management, free cash flow generation and continued deleveraging," McMonagle added.

Each of Adjusted Gross Profit and Adjusted EBITDA is a non-GAAP measure. Further information and reconciliations for our non-GAAP measures to the most directly comparable financial measure under United States generally accepted accounting principles ("GAAP") are included at the end of this press release. CTOS is unable to present a quantitative reconciliation of its forward-looking Adjusted EBITDA for the year ending December 31, 2026 to its most directly comparable GAAP financial measure due to the high variability and difficulty in predicting certain items that affect Adjusted EBITDA including, but not limited to, customer buyout requests on rentals with rental purchase options and income tax expense. Adjusted EBITDA should not be used to predict Net income (loss) as the difference between the measures are variable and unpredictable.

Summary Actual Financial Results by Segment

Beginning January 1, 2026, CTOS is reporting our results under two reportable segments: (1) Specialty Equipment Rentals ("SER") and (2) Specialty Truck Equipment and Manufacturing ("STEM"). The new SER segment consists of our historical Equipment Rental Solutions ("ERS") segment (except for certain used sales to be accounted for by STEM) and a portion of our historical Aftermarket Parts and Services ("APS") segment, and the new STEM segment will consist of our historical Truck and Equipment Sales ("TES") segment, certain used sales that previously were accounted for by ERS and a portion of our historical APS segment. We are also reflecting intercompany activity between the two segments, which is ultimately eliminated in consolidation. This new segment reporting reflects how CTOS's business is managed and how resources are allocated in 2026 and utilizes Adjusted EBITDA as the segments' profit measure. Segment Adjusted EBITDA is defined as segment operating income or loss before depreciation and amortization, further excluding the effects of purchase accounting adjustments and the impact of sales-type lease accounting for certain leases containing rental purchase options (or "RPOs").

Management believes this new presentation better reflects the positioning of CTOS's strategies and operations portfolio and better reflects key economic drivers, capital intensity, and margin profiles of the respective new segments, as well as aligns our external reporting with how management allocates capital and evaluates performance. Prior period amounts have been recast to reflect the change to two reportable segments.

1		Specifically identifiable lease revenue receivables not deemed probable of collection are recorded as a reduction of rental revenue. This is classified as a segment expense for Segment Adjusted EBITDA reviewed by the chief operating decision maker.
2		Impact of sales-type lease accounting for certain leases containing RPOs: this impact is excluded from the measure of Adjusted EBITDA utilized by our CODM to allocate resources and to assess the performance of our segments as 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.
3		Excludes the non-cash impact of purchase accounting, impact of sales-type lease accounting for certain leases containing RPOs, further excluding depreciation.

(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.

Management Commentary

The increase of 18% in rental revenue in the first quarter of 2026 compared to the first quarter of 2025 was the result of improved average fleet utilization (which increased to 81.4% compared to 77.7%) driven by increased rental volume, with average OEC on rent increasing by 12% year-over-year. Compared to the first quarter of 2025, SER rental equipment sales increased 26.5% in the first quarter of 2026 due to an increase in buyout activity of rental contracts with purchase options. SER adjusted EBITDA in the first quarter of 2026 increased 24% compared to the first quarter of 2025.

Equipment sales in our STEM segment increased 4.4% in the first quarter of 2026 compared to the first quarter of 2025 driven by demand for forestry vehicles. Adjusted EBITDA increased by $19.8 million in the first quarter of 2026 compared to the first quarter of 2025. Our STEM backlog was down 2% compared to the first quarter of 2025, and remains within our expected range of four to six months.

The decrease in net loss in the first quarter of 2026 compared to the first quarter of 2025 was primarily due to higher operating income as a result of higher rental revenue driven by higher average OEC on rent as well as strong new equipment sales.

Adjusted EBITDA for the first quarter of 2026 was $98.0 million, a 33.4% increase compared to the first quarter of 2025, which was largely driven by increased gross profit and lower interest expense on variable-rate floor plan liabilities from lower inventory levels.

As of March 31, 2026, cash and cash equivalents were $9.6 million, total debt outstanding was $1,648.5 million, net debt was $1,638.9 million and our net leverage ratio was 4.02x. Availability under the senior secured credit facility was $256.9 million as of March 31, 2026, and based on our borrowing base, we have an additional $191.6 million of suppressed availability that we can potentially utilize by upsizing our existing facility.

2026 Outlook

We are reaffirming our full year consolidated revenue for 2026 and increasing our Adjusted EBITDA^{1, 4} guidance to reflect our strong first quarter and continued momentum in the rental business.

Consolidated CTOS:

Revenue is expected to increase 3% to 9% year-over-year, with Adjusted EBITDA^{1, 4} expected to increase 8% to 15%
Net rental fleet investment (purchases less proceeds) for 2026 is expected to be approximately $150 million to $170 million, with mid-single digit net OEC growth, reflecting a meaningful reduction from over $250 million in 2025
Inventory months on hand is expected to continue trending toward the targeted level of below six months, supporting working capital improvement; and
Levered free cash flow^{2, 4} is expected to exceed $50 million for 2026 and net leverage ratio^{3, 4} is expected to be meaningfully below four times by the end of fiscal 2026; the longer-term target remains achieving a net leverage ratio^{3, 4}below three times in 2027.

Specialty Equipment Rentals (SER):

The rental business continues to perform very strong with OEC on rent, utilization and gross margin all continuing to perform ahead of expectations in 2026
Demand for equipment serving the utility transmission and distribution market remains very strong and at record levels, and further penetration of the vocational rental market is expected to provide incremental growth
Average fleet age ended 2025 at just over 2.9 years, which positioned the Company to reduce rental fleet investment while continuing to pursue growth, with OEC expected to increase by a mid-single digit percentage in 2026. Average fleet age at the end of the first quarter was just under 3 years, aging slightly.

Specialty Truck Equipment & Manufacturing (STEM):

Third-party new sales revenue is expected to increase 3% to 10% in 2026 compared to 2025, supported by continued customer demand, stable supply chain conditions and relationships with key customers, chassis suppliers and attachment suppliers
Total STEM revenue is expected to be down modestly to flat year-over-year due solely to lower intercompany rental sales/capex
Sales order backlog increased by over $55 million (nearly 20%) in the fourth quarter of 2025 and a further $76 million (nearly 23%) in the first quarter of 2026, currently sitting at 4.5 months LTM third-party new sales and remains within the targeted range of four to six months

"Looking ahead, our focus in 2026 is on disciplined execution – translating strong end-market demand into profitable growth, free cash flow generation, and further balance sheet improvement. Our rental business continues to perform very strong, driven by demand in our utility transmission and distribution markets, and we are seeing the benefit of that strength flow through to margins and Adjusted EBITDA^{1, 4}. We expect to show flat revenue and single digit year-over-year Adjusted EBITDA^{1, 4} growth in the second quarter. With a younger, highly utilized fleet and improving working capital dynamics, we believe CTOS is positioned to drive higher returns on invested capital while maintaining financial flexibility as we invest selectively to support our customers' long-term needs, and to translate that into meaningful free cash flow generation," said Chris Eperjesy, Chief Financial Officer of CTOS.

2026 Consolidated Outlook
Revenue	$2,005 million	—	$2,120 million
Adjusted EBITDA^{1, 4}	$415 million	—	$440 million

2026 Revenue Outlook by Segment⁵
SER	$835 million	—	$870 million
STEM	$1,580 million	—	$1,655 million

1		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. Refer to the section below entitled "Non-GAAP Financial and Performance Measures" for further information about Adjusted EBITDA.
2		Levered Free Cash Flow is defined as net cash provided by operating activities, less cash flow for investing activities, excluding acquisitions, plus acquisition of inventory through floor plan payables – non-trade less repayment of floor plan payables – non-trade, both of which are included in cash flow from financing activities in our Consolidated Statements of Cash Flows.
3		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. Refer to the section below entitled "Non-GAAP Financial and Performance Measures" for further information about net leverage ratio.
4		CTOS is unable to present a quantitative reconciliation of its forward-looking Adjusted EBITDA, Levered Free Cash Flow, and Net Leverage Ratio for future periods to their respective most directly comparable GAAP financial measure due to the high variability and difficulty in predicting certain items that affect such GAAP measures including, but not limited to, customer buyout requests on rentals with rental purchase options and income tax expense. Adjusted EBITDA, Levered Free Cash Flow, and Net Leverage Ratio should not be used to predict their respective most directly comparable GAAP measure as the differences between the respective measures are variable and unpredictable.
5		Beginning January 1, 2026, transactions between segments are accounted for as if completed on an arm's length basis using a cost-plus methodology.

NON-GAAP FINANCIAL AND PERFORMANCE MEASURES

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 (excluding interest on floorplan financing), 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 (excluding interest on floorplan financing), 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:
