We rent, produce, sell and service a broad range of new and used equipment, including bucket trucks, digger derricks, dump trucks, cranes, service trucks, and heavy-haul trailers. We manage the business inthree reporting segments: Equipment Rental Solutions (“ERS”), Truck and Equipment Sales (“TES”) and Aftermarket Parts and Services (“APS”).

Basis of Presentation

Our accompanying condensed consolidated financial statements have been prepared in accordance with United States generally accepted accounting principles (“GAAP”). Our condensed consolidated financial statements include the accounts of all wholly-owned subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation. The preparation of financial statements in accordance with GAAP requires that these Unaudited Condensed Consolidated Financial Statements and most of the disclosures in these Notes be presented on a historical basis, as of or for the current interim period ended or comparable prior period.

The accompanying interim statements of the Company have been prepared in accordance with GAAP for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X, and the Condensed Consolidated Balance Sheet at December 31, 2024 has been derived from the audited consolidated financial statements of Custom Truck One Source, Inc. at that date. Accordingly, these interim financial statements do not include all of the information and footnotes required by GAAP for complete financial statements. In the opinion of management, all adjustments, consisting of normal recurring adjustments and disclosures necessary for a fair statement of these interim statements, have been included. The results reported in these interim statements are not necessarily indicative of the results that may be reported for the entire year or for any other periods. These interim statements should be read in conjunction with the Custom Truck One Source, Inc. audited consolidated financial statements included in the Custom Truck One Source, Inc. Annual Report on Form 10-K for the year ended December 31, 2024.

Use of Estimates

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates.

Recently Adopted Accounting Standards

In December 2023, the Financial Accounting Standards Board (the “FASB”) issued Accounting Standards Update No. 2023-09, Income Taxes—Improvements to Income Tax Disclosures (Topic 740) (“ASU 2023-09”), which expands income tax disclosure requirements to include additional information related to the rate reconciliation of our effective tax rates to statutory rates as well as additional disaggregation of taxes paid. The amendments in the ASU also remove disclosures related to certain unrecognized tax benefits and deferred taxes. ASU 2023-09 is effective for fiscal years beginning after December 15, 2024. The amendments may be applied prospectively or retrospectively. The Company adopted ASU 2023-09 on January 1, 2025, and will include the newly required disclosures in the notes to its consolidated financial statements in its Annual Report on Form 10-K for the fiscal year ending December 31, 2025.

Recently Issued Accounting Standards

In September 2025, the FASB issued Accounting Standards Update No. 2025-06, Intangibles — Goodwill and Other — Internal-Use Software (“ASU 2025-06”), which amends the guidance for accounting for software costs to reflect current software development practices, including iterative and agile methodologies, by removing references to development stages. It also clarifies the criteria for capitalization, which begins when both of the following occur: (1) management has authorized and committed to funding the software project and (2) it is probable that the project will be completed and the software will be used to perform the function intended. ASU 2025-06 is effective for fiscal years beginning after December 15, 2027, and interim periods within those fiscal years. Early adoption is permitted. The amendments may be applied either prospectively, retrospectively, or utilizing a modified transition approach. The Company is currently assessing the impact of ASU 2025-06 on its condensed consolidated financial statements and disclosures.

In November 2024, the FASB issued Accounting Standards Update No. 2024-03, Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses (“ASU 2024-03”), which requires additional disclosures in the notes to financial statements, disaggregating specific expense categories within relevant income statement captions. The FASB further clarified the effective date in January 2025 with the issuance of ASU 2025-01, Income Statement — Reporting Comprehensive Income — Expense Disaggregation Disclosures (Subtopic 220-40): Clarifying the Effective Date (“ASU 2025-01”). ASU 2024-03 is effective for fiscal years beginning after December 15, 2026, and interim periods within fiscal years beginning after December 15, 2027. Early adoption is permitted. The Company is currently assessing the impact of the requirements on its condensed consolidated financial statements and disclosures.

Note 2: Revenue

Revenue Disaggregation

Geographic Areas

The Company had total revenue in the following geographic areas:

Major Product Lines and Services

Equipment leasing and equipment sales are the core businesses of the Company, with leasing complemented by the sale of rental units from the rental fleet. The Company’s revenue by major product and service line for the three and nine months ended September 30, 2025 and 2024 are presented in the table below.

Rental revenue is primarily comprised of revenues from rental agreements and freight charges billed to customers. Equipment sales recognized pursuant to sales-type leases are recorded within equipment sales revenue. Charges to customers for damaged rental equipment are recorded within parts and services revenue.

Receivables, Contract Assets and Liabilities

As of September 30, 2025 and December 31, 2024, the Company had net receivables related to contracts with customers of $85.5 million and $119.9 million, respectively. As of September 30, 2025 and December 31, 2024, the Company had net receivables related to rental contracts of $96.7 million and $95.9 million, respectively.

The Company manages credit risk associated with its accounts receivable at the customer level. Because the same customers generate the revenues that are accounted for under both Topic 606 and Topic 842, the discussions below address how credit risk and the Company's allowance for credit losses impact the Company's total revenues.

The Company’s allowance for credit losses reflects its estimate of the amount of receivables that it will be unable to collect. The estimated losses are calculated using the loss rate method based upon a review of outstanding receivables, related aging, including specific accounts if deemed necessary, and on the Company’s historical collection experience. The Company's estimates reflect changing circumstances, including changes in the economy or in the particular circumstances of individual customers, and, as a result, the Company may be required to increase or decrease its allowance.

Accounts receivable, net consisted of the following:

For the nine months ended September 30, 2025 and 2024, the Company wrote-off $8.0 million and $8.4 million, respectively, of receivables, net of recoveries.

When customers are billed for rentals in advance of the rental period, the Company defers recognition of revenue. As of September 30, 2025 and December 31, 2024, the Company had approximately $6.2 million and $4.8 million, respectively, of deferred rental revenue. All of the $4.8 million deferred rental revenue as of December 31, 2024 was recognized during the nine months ended September 30, 2025. Additionally, the Company collects deposits from customers for orders placed for equipment and rentals. The Company had approximately $21.2 million and $21.5 million in deposits as of September 30, 2025 and December 31, 2024, respectively. All of the $21.5 million deposit liability balance as of December 31, 2024 was recorded as revenue during the nine months ended September 30, 2025 due to performance obligations being satisfied. The Company’s remaining performance obligations on its equipment deposit liabilities have original expected durations ofone year or less.

The Company does not have material contract assets, and as such, did not recognize any material impairments of any contract assets.

Note 3: Sales-Type Leases

Revenue from rental agreements qualifying as sales-type leases was as follows:

As these transactions remained under rental contracts, $1.6 million and $3.7 million for the three months ended September 30, 2025 and 2024, respectively, and $5.3 million and $14.6 million for the nine months ended September 30, 2025 and 2024, respectively, were billed under the contracts as rentals. Interest income from financing receivables was $0.9 million and $2.8 million for the three months ended September 30, 2025 and 2024, respectively, and $3.2 million and $8.8 million for the nine months ended September 30, 2025 and 2024, respectively.

Note 4: Inventory

Whole goods inventory is comprised of chassis, attachments (i.e., boom cranes, aerial lifts, digger derricks, dump bodies, etc.) and the in-process costs incurred in the final assembly of those units. As part of the business model, the Company sells unassembled individual whole goods and whole goods with varying levels of customization direct to consumers or dealers. Whole goods inventory also includes new equipment purchased specifically for resale to customers. Inventory consisted of the following:

Note 5: Floor Plan Financing

Floor plan payables represent financing arrangements to facilitate the Company’s purchase of new and used trucks, cranes, and construction equipment inventory. All floor plan payables are collateralized by the inventory financed. These payables become due and payable upon the sale, transfer, or reclassification of each unit of inventory. Certain floor plan arrangements require the Company to satisfy various financial ratios consistent with those under the ABL Facility (as defined below). As of September 30, 2025, the Company was in compliance with these covenants.

The amounts owed under floor plan payables are summarized as follows:

Interest on outstanding floor plan payable balances is due and payable monthly. Floor plan interest expense was $13.8 million and $40.8 million for the three and nine months ended September 30, 2025, respectively, and $16.7 million and $45.0 million for the same periods in 2024.

Daimler Truck Financial

The Company is party to the Wholesale Financing Agreement with Daimler Truck Financial (the “Daimler Facility”), which bore interest at a rate of U.S. Prime Rate plus 0.80% after an initial interest free period of up to 150 days. On January 1, 2025, the interest rate was updated to U.S. Prime Rate. The total borrowing capacity under the Daimler Facility is $225.0 million, however, from time to time, Daimler extends credit to the Company in excess of this amount.

The total borrowing capacity under the FMCC Facility is $42.0 million. The FMCC agreement is evergreen and is subject to termination by either party through written notice.

References to the U.S. Prime Rate in the foregoing agreements represent the rate as published in The Wall Street Journal.

Non-Trade Floor Plan Financing:

PNC Equipment Finance, LLC

On August 25, 2025, the Company renewed the Loan Agreement for an additionalone year. The Loan Agreement, as of September 30, 2025, provides the Company with a $475.0 million revolving credit facility, which matures on August 25, 2026 and bears interest at a three-month term secured overnight financing rate (“SOFR”) plus 3.00%.

Note 6: Rental Equipment

Rental equipment, net consisted of the following:

Note 7: Long-Term Debt

Debt obligations and associated interest rates consisted of the following:

As of September 30, 2025, borrowing availability under the ABL Facility was $237.6 million, and outstanding standby letters of credit were $3.9 million.

ABL Facility

The Company and certain of its direct and indirect subsidiaries are party to an asset-based revolving credit agreement (the “ABL Credit Agreement”), consisting of a $950.0 million first lien senior secured asset-based revolving credit facility (the “ABL Facility”), which matures on August 9, 2029, or, if earlier, the date that is 91 days prior to the maturity date of the Company’s existing senior notes or any debt that refinances such existing notes. Borrowings under the ABL Facility bear interest at a floating rate, which, at the Company’s election, could be (a) in the case of U.S. dollar denominated loans, either (i) SOFR plus an applicable margin or (ii) the base rate plus an applicable margin; or (b) in the case of Canadian dollar denominated loans, the term Canadian Overnight Repo Rate Average (the “CORRA” rate) plus an applicable margin. The applicable margin varies based on Average Availability (as defined in the ABL Credit Agreement) from (a) with respect to base rate loans,0.50% to 1.00% and (b) with respect to SOFR loans and CORRA rate loans,1.50% to 2.00%.

Note 8: Earnings (Loss) Per Share

Basic earnings (loss) per share is computed by dividing net earnings (loss) by the weighted-average number of shares of common stock outstanding. Diluted earnings (loss) per share includes the effects of potentially dilutive shares of common stock, if dilutive. Potentially dilutive effects include the exercise of warrants, contingently issuable shares, and share-based compensation. On July 31, 2024, all of the Company’s stock purchase warrants expired and were unexercised. Our potentially dilutive shares aggregated 4.3 million for both the three and nine months ended September 30, 2025, and 9.8 million and 24.8 million for the same periods in 2024, and were not included in the computation of diluted earnings (loss) per share because the impact would have been anti-dilutive. The Company hadno dilutive common share equivalents during the three and nine months ended September 30, 2025 and 2024 due to results from continuing operations being a loss, net of tax.

Note 9: Equity

Preferred Stock

As of both September 30, 2025, and December 31, 2024, we were authorized to issue 10,000,000 shares of preferred stock with a par value of $0.0001 per share, with such designation, rights and preferences as may be determined from time to time by our board of directors. As of both September 30, 2025, and December 31, 2024, there wereno shares of preferred stock issued or outstanding.

Common Stock

As of both September 30, 2025, and December 31, 2024, we were authorized to issue 500,000,000 shares of common stock with a par value of $0.0001 per share.

On August 2, 2022, the Company’s Board of Directors authorized a stock repurchase program, allowing for the repurchase of up to $30 million of the Company’s shares of common stock, which authorization was further increased by $25 million of shares on September 14, 2023, and increased again by $25 million of shares on March 11, 2024, upon exhaustion of prior authorization. Under the repurchase program, repurchases can be made from time to time using a variety of methods, which may include open market purchases, privately negotiated transactions, or otherwise, all in accordance with the rules of the Securities and Exchange Commission and other applicable legal requirements. The specific timing, price and size of purchases will depend on prevailing stock prices, general economic and market conditions, and other considerations. The repurchase program does not obligate the Company to acquire any particular amount of its common stock, and the repurchase program may be suspended or discontinued at any time at the Company’s discretion. At September 30, 2025, $1.9 million was available under the stock repurchase program.

Earnout Shares

Pursuant to the Stockholders’ Agreement dated July 31, 2019 (as amended and restated from time to time, the “Stockholders’ Agreement”), certain stockholders agreed to restrictions on approximately 3,100,000 of their shares of the Company’s common stock (the “Earnout Shares”). The Earnout Shares shall be automatically forfeited by the holders thereof to the Company for no consideration with respect to (i)2.8 million shares unless the trading price of the common stock equals or exceeds certain price targets by July 31 2024 (the “Minimum and Second Target Earnout Shares”), which Minimum and Second Target Earnout Shares were forfeited on July 31, 2024; and (ii) approximately 0.3 million shares unless the trading price of the common stock equals or exceeds $19.00 per share for any period of 20 trading days out of 30 consecutive trading days to and including July 31, 2026 (the “Maximum Target Earnout Shares”).

Energy Capital Partners Stock Repurchase

NESCO Holdings, LP is a Delaware limited partnership which held shares of our common stock. NESCO Holdings, LP is owned and controlled by Energy Capital Partners (“ECP”). On January 30, 2025, the Company purchased 8,143,635 shares of the Company’s common stock from affiliates of ECP (“Repurchase from ECP”), at a purchase price of $4.00 per share, which represents an approximately 23% discount from the price of $5.19 per share of common stock at the close of trading on January 29, 2025, for an aggregate purchase price of $32.6 million. The transaction was approved by the Company’s Board of Directors and the Audit Committee of the Board of Directors and the purchased shares are held in treasury.

Note 10: Fair Value Measurements

The FASB accounting standards provide a comprehensive framework for measuring fair value and sets forth a definition of fair value and establishes a hierarchy prioritizing the inputs to valuation techniques, giving the highest priority to quoted prices in active markets for identical assets and liabilities and the lowest priority to unobservable value inputs.

The following table sets forth the carrying values (exclusive of deferred financing fees) and fair values of our financial liabilities:

The carrying amounts of the ABL Facility, 2023 Credit Facility and other notes payable approximated fair value as of September 30, 2025, and December 31, 2024, based upon terms and conditions available to the Company at those dates in comparison to the terms and conditions of its outstanding debt. The estimated fair value of the 2029 Secured Notes is calculated using Level 2 inputs, based on bid prices obtained from brokers.

Note 11: Income Taxes

Interim Income Tax Expense (Benefit) – Our income tax expense or benefit reflects a combination of income taxes in foreign jurisdictions and certain U.S. states. We have federal and state net operating loss carryforwards (“NOLs”) and non-deductible interest expense carryforwards in the U.S. that may be applied to reduce taxable income in current and future tax years. Some of these carryforwards are subject to annual usage limitations and expiration, while other state NOLs and a portion of federal NOLs do not have limitations or expiration. We carry a valuation allowance against our U.S. carryforwards, which results in no net income tax expense in our earnings in periods when additional NOLs are generated or when existing NOLs are utilized. Certain states that we operate in have rules regarding the deductibility of items that diverge from U.S. federal deductibility rules and in addition, a number of these states have placed limitations on the usage of NOLs to offset taxable income apportioned to those states. Our overall effective tax rate is affected by a number of factors, including the relative amounts of income we earn in different tax jurisdictions, tax law changes, certain non-deductible expenses, the changes in our valuation allowance and divergence of state rules from federal rules. The factors result in an effective tax rate that differs from statutory rates.

For interim periods, we estimate our annual effective tax rate, exclusive of discrete items, which is derived primarily by our estimate of taxable income or losses for our applicable jurisdictions together with estimates of changes to our valuation allowance. The estimated annual effective tax rate is recorded in interim periods based on year-to-date income or loss before income taxes. Accordingly, income tax expense or benefit in quarterly periods reflects the impacts of changes to our annual effective tax rate. Because of the impacts of (i) the U.S. carryforwards’ valuation allowances, (ii) taxes in foreign jurisdictions and (iii) taxes in U.S. states that diverge from U.S. federal deductibility rules, our effective tax rate may fluctuate between a positive and a negative rate. For the nine months ended September 30, 2025, our income tax expense is comprised of $8.0 million of state income tax expense and $0.8 million of foreign income tax expense, resulting in an effective tax rate of (20.4)%. The effective tax rate was (0.9)% for the nine months ended September 30, 2024.

Recent Tax Legislation – On July 4, 2025, the President signed the One Big Beautiful Bill Act (the “OBBBA”) into law. This act introduces significant changes to tax law and other areas affecting company operations, including items such as extensions of provisions previously enacted under the 2017 Tax Cuts and Jobs Act, changes to business interest deductions, or modifications to depreciation deductions and impacts on energy tax credits. We are evaluating the potential impact of the OBBBA on our financial statements.

Note 12: Commitments and Contingencies

We record a liability when we believe that it is both probable that a liability has been incurred and the amount can be reasonably estimated. Significant judgment is required to determine both probability and the estimated amount. We review these provisions at least quarterly and adjust these provisions to reflect the impact of negotiations, settlements, rulings, advice of legal counsel, and updated information.

Legal Matters

In the normal course of business, there are various claims in process, matters in litigation, and other contingencies. At this time, no claims of these types, certain of which are covered by insurance policies, have had a material effect on the Company. Certain jurisdictions in which the Company operates do not allow insurance recoveries related to punitive damages. For matters pertaining to the pre-acquisition activities of Custom Truck One Source, L.P. (“Custom Truck LP”), the sellers of Custom Truck LP have agreed to indemnify the Company for losses arising out of the breach of pre-closing covenants in the purchase agreement and certain indemnified tax matters discussed below, with recourse limited to $10.0 million and $5.0 million escrow accounts, respectively.

From time to time, the Company is audited by state and local taxing authorities. These audits typically focus on the Company’s withholding of state-specific sales tax and rental-related taxes.

Custom Truck LP’s withholdings of federal excise taxes for each of the four quarterly periods during 2015 are currently under audit by the IRS. The IRS issued an assessment on October 28, 2020 in an aggregate amount of $2.4 million for the 2015 periods, alleging that certain types of sold equipment are not eligible for the Mobile Machinery Exemption set forth in the Internal Revenue Code (the “Code”). An appeal was filed on January 28, 2021. Based on management’s understanding of the facts and circumstances, including the relevant provisions of the Code, and historical precedent, including previous successful appeals of similar assessments in prior years, management does not believe the likelihood of a loss resulting from the IRS assessment to be probable at this time.

While it is not possible to predict the outcome of the foregoing matters with certainty, it is the opinion of management that the final outcome of these matters will not have a material effect on the Company’s consolidated financial condition, results of operations and cash flows.

Purchase Commitments

We enter into purchase agreements with manufacturers and suppliers of equipment for our rental fleet and inventory. All of these agreements are cancellable within a specified notification period to the supplier.

Note 13: Related Parties

Amounts receivable from/payable to related parties included in the Condensed Consolidated Balance Sheets are as follows:

Note 14: Segments

Our operations are primarily organized and managed by operating segment. Operating segment performance and resource allocations are primarily based on gross profit. Gross profit aids the Chief Operating Decision Maker (“CODM”) in managing the inventory levels and rental fleet, entering into significant revenue contracts, expanding into new markets or launching new products, making capital expenditures, designing and implementing key marketing strategies, personnel changes, and approving operating budgets. Significant expense categories that are regularly reviewed by the operating segments’ CODM are disclosed below. The CODM for all segments is the Company’s Chief Executive Officer. We manage the business inthree reporting segments: Equipment Rental Solutions (“ERS”), Truck and Equipment Sales (“TES”) and Aftermarket Parts and Services (“APS”). Transactions between our segments consist of equipment produced by TES that is sold to ERS for inclusion in its fleet of rental equipment. Additionally, TES and APS provide repair and maintenance services to ERS for maintenance of its rental fleet. Transactions between segments are at cost and intersegment sales and purchases are eliminated in consolidation.

The Company’s segment results are presented in the tables below:

Total assets by operating segment are not disclosed herein because assets by operating segment data is not reviewed by the CODM to assess performance and allocate resources.

Gross profit is the primary operating result whereby our segments are evaluated for performance and resource allocation. The following table presents a reconciliation of consolidated gross profit to consolidated income (loss) before income taxes:

The following table presents total assets by country:
