Accounting Policies [Abstract]  
Overview and Summary of Significant Accounting Policies Overview and Summary of Significant Accounting Policies
Basis of Presentation
Arcosa, Inc. and its consolidated subsidiaries (“Arcosa,” the “Company,” “we,” or “our”), headquartered in Dallas, Texas, is a provider of infrastructure-related products and solutions with leading brands serving construction, engineered structures, and transportation markets in North America. Arcosa is a Delaware corporation and was incorporated in 2018.
The accompanying Consolidated Financial Statements are unaudited and have been prepared from the books and records of Arcosa, Inc. and its consolidated subsidiaries. All normal and recurring adjustments necessary for a fair presentation of the financial position of the Company and the results of operations, comprehensive income/loss, and cash flows have been made in conformity with accounting principles generally accepted in the U.S. (“GAAP”). All significant intercompany accounts and transactions have been eliminated. Because of seasonal and other factors, the financial condition and results of operations for the three and nine months ended September 30, 2025 may not be indicative of Arcosa's expected business, financial condition, and results of operations for the year ending December 31, 2025.
These interim financial statements and notes are condensed as permitted by the instructions to Form 10-Q and should be read in conjunction with the audited Consolidated Financial Statements of the Company included in its Annual Report on Form 10-K for the year ended December 31, 2024.
Stockholders' Equity
In December 2024, the Company’s Board of Directors (the “Board") authorized a $50.0 million share repurchase program effective January 1, 2025 through December 31, 2026 to replace an expiring program of the same amount. For the three and nine months ended September 30, 2025, the Company did not repurchase any shares, leaving the full amount of the $50.0 million authorization available as of September 30, 2025.
Revenue Recognition
Revenue is measured based on the allocation of the transaction price in a contract to satisfied performance obligations. The transaction price does not include any amounts collected on behalf of third parties. The Company recognizes revenue when it satisfies a performance obligation by transferring control over a product or service to a customer. The following is a description of principal activities from which the Company generates its revenue, separated by reportable segments. Payments for our products and services are generally due within normal commercial terms. For a further discussion regarding the Company’s reportable segments, see Note 4 Segment Information.
Construction Products
The Construction Products segment primarily recognizes revenue when the customer has accepted the product and legal title of the product has passed to the customer.
Engineered Structures
Within the Engineered Structures segment, revenue is recognized for wind towers and certain utility structures over time as the products are manufactured using an input approach based on the costs incurred relative to the total estimated costs of production. We recognize revenue over time for these products as they are highly customized to the needs of an individual customer resulting in no alternative use to the Company if not purchased by the customer after the contract is executed. In addition, we have the right to bill the customer for our work performed to date plus at least a reasonable profit margin for work performed. As of September 30, 2025, we had a contract asset of $78.6 million related to these contracts, compared to $65.5 million as of December 31, 2024, which is included in receivables, net of allowance, within the Consolidated Balance Sheets. The increase in the contract asset is attributed to timing of deliveries of finished structures to customers during the period. For all other products, revenue is recognized when the customer has accepted the product and legal title of the product has passed to the customer.
Transportation Products
The Transportation Products segment recognizes revenue when the customer has accepted the product and legal title of the product has passed to the customer.

In our Engineered Structures segment, 43% of the unsatisfied performance obligations for our utility and related structures are expected to be recognized during 2025, and substantially all of the remaining performance obligations are expected to be recognized in 2026. For our wind towers business, 18% of the unsatisfied performance obligations are expected to be recognized during 2025, with the remainder expected to be recognized through 2027.
For inland barges in our Transportation Products segment, 30% of the unsatisfied performance obligations are expected to be recognized during 2025, and the remainder are expected to be recognized in 2026.
Income Taxes
The liability method is used to account for income taxes. Deferred income taxes represent the tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. Valuation allowances reduce deferred tax assets to an amount that will more likely than not be realized.
The Company regularly evaluates the likelihood of realization of tax benefits derived from positions it has taken in various federal and state filings after consideration of all relevant facts, circumstances, and available information. For those tax positions that are deemed more likely than not to be sustained, the Company recognizes the benefit it believes is cumulatively greater than 50% likely to be realized. To the extent the Company were to prevail in matters for which accruals have been established or be required to pay amounts in excess of recorded reserves, the effective tax rate in a given financial statement period could be materially impacted.
Financial Instruments
The Company considers all highly liquid debt instruments to be cash and cash equivalents if purchased with a maturity of three months or less. Financial instruments that potentially subject the Company to a concentration of credit risk are primarily cash investments and receivables. The Company places its cash investments in bank deposits and highly-rated money market funds, and its investment policy limits the amount of credit exposure to any one commercial issuer. We seek to limit concentration of credit risk with respect to the Company's receivables with control procedures that monitor the credit worthiness of customers, together with the large number of customers in the Company's customer base and their dispersion across different industries and geographic areas. As receivables are generally unsecured, the Company maintains an allowance based upon the expected credit losses. Receivable balances determined to be uncollectible are charged against the allowance. To accelerate the conversion to cash, the Company may sell a portion of its trade receivables to third parties. The Company has no recourse to these receivables once they are sold but may have continuing involvement related to servicing and collection activities. The impact of these transactions in the Company's Consolidated Statements of Operations for the three and nine months ended September 30, 2025 was not significant. The carrying values of cash, receivables, and accounts payable are considered to be representative of their respective fair values.
Recent Accounting Pronouncements
Recently adopted accounting pronouncements
Effective January 1, 2025, the Company adopted Accounting Standards Update No. 2023-09, “Income Taxes (Topic 740): Improvements to Income Tax Disclosures” (“ASU 2023-09”), which is intended to improve the transparency of income tax disclosures by requiring 1) consistent categories and greater disaggregation of information in the rate reconciliation and 2) income taxes paid disaggregated by jurisdiction. The standard also includes certain other amendments to improve the effectiveness of income tax disclosures. The additional disclosure requirements will be reflected in our Annual Report on Form 10-K for the year ending December 31, 2025. As ASU 2023-09 only modifies the Company's required income tax disclosures, the adoption of this guidance did not have a material impact on the Company's Consolidated Financial Statements.
Effective January 1, 2024, the Company adopted Accounting Standards Update No. 2023-07, “Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures” (“ASU 2023-07”), which is intended to improve reportable segment disclosure requirements, primarily through enhanced disclosures about significant segment expenses. The adoption of this guidance did not have a material effect on the Company's Consolidated Financial Statements.
Recently issued accounting pronouncements not adopted as of September 30, 2025
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 public business entities to disclose additional information about certain key expense categories within major income statement captions in the notes to consolidated financial statements. These enhanced disclosures are expected to help investors more effectively understand an entity's performance, assess its prospects for future cash flows, and compare an entity's performance over time and with that of other entities. ASU 2024-03 is effective for annual reporting periods beginning after December 15, 2026, and interim reporting periods beginning after December 15, 2027, and may be applied either prospectively or retrospectively. Early adoption is permitted. The Company is currently evaluating the impact of adopting ASU 2024-03 on its Consolidated Financial Statements.

Business Combination [Abstract]  
Acquisitions and Divestitures
2025 Acquisitions
There were no acquisitions completed during the three and nine months ended September 30, 2025.
2024 Acquisitions
On October 1, 2024, we acquired substantially all of the construction materials business of Stavola Holding Corporation and its affiliated entities ("Stavola") for $1.2 billion in cash, subject to certain customary purchase price adjustments. The purchase price was funded with a combination of proceeds from a private offering of $600.0 million of 6.875% senior unsecured notes that closed on August 26, 2024 and $700.0 million in borrowings under a variable-rate secured term loan entered into on October 1, 2024. See Note 7 Debt for additional information. Stavola, which is included in our Construction Products segment, is an aggregates-led and vertically integrated construction materials company primarily serving the New York-New Jersey Metropolitan Statistical Area ("MSA") through its network of five hard rock natural aggregates quarries, twelve asphalt plants, and three recycled aggregates sites. The Stavola acquisition expanded our platform into the nation's largest MSA with industry-leading financial attributes. During the nine months ended September 30, 2025, the Company received $17.6 million from escrow related to purchase price adjustments in accordance with the terms of the purchase agreement for the Stavola acquisition, which reduced the total purchase price consideration.
The Stavola acquisition was recorded as a business combination based on a valuation of assets acquired and liabilities assumed at their acquisition date fair values using unobservable inputs that are supported by little or no market activity and are significant to the fair value of the assets and liabilities ("Level 3" inputs). The following table details the final purchase price allocation:

Other assets23.2 
Accounts payable(18.0)
Accrued liabilities(2.6)
Advance billings(0.8)
Other liabilities(28.1)
Total net assets acquired$1,192.0 
Goodwill represents the excess of the purchase consideration over the valuation of the net assets acquired. The acquired goodwill, which has been assigned to the Construction Products segment, is tax-deductible and primarily attributable to Stavola's market position and existing workforce. The acquired intangibles include beneficial use rights, recycling permits, and the Stavola trade name, which have a useful life of 34 years, 20 years, and 5 years, respectively.
On the acquisition date, the Company also entered into three separate lease agreements for properties owned by the sellers. These lease agreements were accounted for separately from the Stavola acquisition, and the corresponding right of use assets and lease liabilities of $12.3 million and $12.6 million, respectively, are reflected in the Consolidated Balance Sheet as of September 30, 2025.
Revenues and operating profit included in the Consolidated Statement of Operations were $102.6 million and $32.3 million, respectively, for the three months ended September 30, 2025, and $219.3 million and $44.2 million, respectively, for the nine months ended September 30, 2025. Non-recurring transaction costs incurred during the three and nine months ended September 30, 2025 were not significant.
In July 2024, we completed the acquisition of a Phoenix, Arizona based natural aggregates business in our Construction Products segment, for a total purchase price of $35.0 million.
In April 2024, we completed the acquisition of Ameron Pole Products LLC ("Ameron"), a leading manufacturer of highly engineered, premium concrete and steel poles for a broad range of infrastructure applications, including lighting, traffic, electric distribution, and small-cell telecom, for a total purchase price of $180.0 million. With operations in Alabama, California, and Oklahoma, Ameron is included in our Engineered Structures segment. The acquisition was funded with $160.0 million of borrowings under our revolving credit facility and cash on hand. The acquisition was recorded as a business combination based on a valuation of the assets acquired and liabilities assumed at their acquisition date fair value using Level 3 inputs. The final valuation resulted in the recognition of, among others, $60.8 million of property, plant, and equipment, $25.6 million of customer relationships, $18.1 million of inventory, $12.8 million of developed technology, $12.0 million of accounts receivable, $8.9 million of trademarks and $42.3 million of goodwill in our Engineered Structures segment. The acquired goodwill, which is tax-deductible, primarily relates to Ameron's market position and existing workforce.
Divestitures
There were no divestitures completed during the three and nine months ended September 30, 2025.
In August 2024, the Company completed the divestiture of its steel components business. The steel components business, previously reported in the Transportation Products segment, was a leading supplier of railcar coupling devices, railcar axles, and circular forgings. The total consideration for the divestiture was $110.0 million consisting of $55.0 million in cash, a $25.0 million seller's note and a $30.0 million earnout, for which the estimated fair value as of September 30, 2025 was $10.8 million. See Note 3 Fair Value Accounting. During the three and nine months ended September 30, 2025, the Company recognized a loss of $3.6 million and $6.1 million, respectively, primarily due to a change in the estimated fair value of the earnout and certain long-term liabilities, which are presented within other operating (income) expense on the Consolidated Statements of Operations. Revenues and operating loss of the steel components business were $13.6 million and $25.4 million, respectively, for the three months ended September 30, 2024, and $87.8 million and $20.9 million, respectively, for the nine months ended September 30, 2024. As the steel components business was not core to Arcosa's long-term strategy, its divestiture was not considered a strategic shift that would have a major effect on the Company's operations or financial results from either a quantitative or qualitative perspective. Accordingly, it is not reported as a discontinued operation.
During the three months ended June 30, 2024, we completed the divestiture of certain assets and liabilities of a single-location asphalt and paving operation in our Construction Products segment and the sale of a non-operating facility in our Engineered Structures segment. The total consideration for these divestitures was $27.3 million.

Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for that asset or liability in an orderly transaction between market participants on the measurement date. An entity is required to establish a fair value hierarchy that maximizes the use of observable inputs and minimizes the use of unobservable inputs when measuring fair value. The three levels of inputs that may be used to measure fair values are listed below:
Level 1 – This level is defined as quoted prices in active markets for identical assets or liabilities. The Company’s cash equivalents are instruments of the U.S. Treasury or highly-rated money market mutual funds.
Level 2 – This level is defined as observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.
Level 3 – This level is defined as unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. Contingent consideration relates to estimated future payments expected from businesses previously acquired or sold. We estimate the fair value of the contingent consideration using a model appropriate for the structure of the contingent consideration, which may include discounted cash flow models, Monte Carlo simulations, or option pricing models. The fair values are sensitive to changes in the forecast of the performance metrics and in other metrics such as discount rates and volatility. The fair value is reassessed quarterly based on assumptions used in our latest projections. See further discussion in Note 2 Acquisitions and Divestitures.

Revolving Credit Facility
In August 2023, we entered into a Second Amended and Restated Credit Agreement (as amended, the "Credit Agreement") to increase our revolving credit facility from $500.0 million to $600.0 million, extend the maturity date of our revolving credit facility from January 2, 2025 to August 23, 2028, and refinance and repay in full the remaining balance of the term loan then outstanding under our prior credit facility.
On August 15, 2024, we entered into Amendment No. 1 to the Credit Agreement ("Amendment No. 1 to the Credit Agreement") to, among other things, (i) increase our revolving credit facility from $600.0 million to $700.0 million, (ii) collateralize the amended revolving credit facility with substantially all of our and our subsidiary guarantors' personal property (with certain exceptions), (iii) make the applicable margin for revolving borrowings, letters of credit and the commitment fee rate be based on our consolidated net leverage ratio (permitting up to $150.0 million of unrestricted cash to be netted from the calculation thereof), (iv) modify the margin for Secured Overnight Financing Rate ("SOFR")-based revolving borrowings and letters of credit to range from 1.25% to 2.50% per annum, (v) modify the margin for base rate revolving borrowings to range from 0.25% to 1.50%, (vi) modify the commitment fee that accrues on the unused portion of the revolving credit facility to range from 0.20% to 0.45%, and (vii) modify the maximum permitted leverage ratio to include a net debt concept (permitting up to $150.0 million of unrestricted cash to be netted from the calculation thereof), and to provide that such ratio shall be no greater than 5.00 to 1.00 during the fourth quarter of 2024 and the next two fiscal quarters, 4.50 to 1.00 for the next following two fiscal quarters, and 4.00 to 1.00 for each fiscal quarter thereafter (however, this maximum permitted leverage ratio may be increased to 4.50 to 1.00 for up to four fiscal quarters if a material acquisition is entered into). These amendments did not become effective until the closing of the Stavola acquisition on October 1, 2024. The amended revolving credit facility's maturity date of August 23, 2028 remains unchanged.
As of September 30, 2025, we had no outstanding loans borrowed under our revolving credit facility, which left $700.0 million available for borrowing.
The interest rates for revolving loans under the Credit Agreement are variable based on the daily simple or term SOFR, plus a 10-basis point credit spread adjustment, or an alternate base rate, in each case plus a margin for borrowing. A commitment fee accrues on the average daily unused portion of the revolving credit facility. The margin for revolving borrowings and commitment fee rate are determined based on the Company’s consolidated total net leverage ratio (as measured by a consolidated funded indebtedness, less the aggregate amount of unrestricted cash up to a maximum amount not to exceed $150.0 million, to consolidated EBITDA ratio). As of September 30, 2025, the margin for borrowing based on SOFR was set at 2.00% and the commitment fee rate was set at 0.35%.
The revolving credit facility portion of the Credit Agreement requires the maintenance of certain ratios related to leverage and interest coverage. As of September 30, 2025, we were in compliance with all such financial covenants. Borrowings under the Credit Agreement are guaranteed by certain domestic subsidiaries of the Company. On October 1, 2024, we collateralized our obligations under the Credit Agreement with substantially all of our and our subsidiary guarantors' personal property (with certain exceptions).
The carrying value of revolving borrowings under the Credit Agreement approximates fair value because the interest rate adjusts to the market interest rate (Level 3 input). See Note 3 Fair Value Accounting.
In connection with the Credit Agreement, the Company incurred debt issuance costs of approximately $1.9 million during the year ended December 31, 2024. As of September 30, 2025, total unamortized debt issuance costs related to the prior and amended revolving credit facilities were $2.9 million. These costs are included in other assets on the Consolidated Balance Sheet and are amortized into interest expense over the term of the Credit Agreement.
Term Loan
Amendment No. 1 to the Credit Agreement provided for a secured term loan facility (the “2024 Term Loan”) in an aggregate principal amount of $700.0 million. The 2024 Term Loan was funded on October 1, 2024 with the closing of the Stavola acquisition, of which $100.0 million was used to pay down the Company's revolving credit facility. The 2024 Term Loan required, among other things, (i) mandatory prepayments from excess cash flow on an annual basis, commencing with the fiscal year ending December 31, 2025, (ii) mandatory prepayments with proceeds of certain asset sales and debt issuances, and (iii) quarterly principal amortization payments in an amount equal to 0.25% of the 2024 Term Loan. The 2024 Term Loan had a maturity date of October 1, 2031. The interest rate for the 2024 Term Loan was based on SOFR plus 2.25% per year. The 2024 Term Loan was prepayable at any time without penalty. The 2024 Term Loan was guaranteed by the same subsidiaries of the Company that guarantee our revolving credit facility, and the 2024 Term Loan was secured on a pari passu basis with our revolving credit facility.
In connection with the issuance of the 2024 Term Loan, the Company incurred $7.0 million of debt issuance costs.
On June 17, 2025, we entered into Amendment No. 2 to the Credit Agreement to establish a new class of term loans (the "2025 Refinancing Term Loan") in an aggregate principal amount of $698.3 million. We used the 2025 Refinancing Term Loan's net proceeds, together with cash on hand, to satisfy the outstanding balance under the 2024 Term Loan. The interest rate for the 2025 Refinancing Term Loan is based on SOFR plus 2.00% per year, or an alternate base rate, plus 1.00% per year, a 0.25% per annum reduction from the 2024 Term Loan. If the 2025 Refinancing Term Loan is prepaid in connection with a repricing transaction or we effect any amendment to the Credit Agreement resulting in a repricing transaction, in either case within six months after the initial funding of the 2025 Refinancing Term Loan, there is a 1.00% premium on such prepaid amount or on the amount outstanding at the time such repricing transaction amendment becomes effective. Otherwise, the 2025 Refinancing Term Loan is prepayable at any time without premium or penalty (other than customary SOFR-related breakage costs). All other terms of the 2025 Refinancing Term Loan are the same as the 2024 Term Loan that was prepaid with the proceeds of the 2025 Refinancing Term Loan. During the nine months ended September 30, 2025, without premium or penalty, the Company prepaid $98.3 million of the outstanding principal balance on the 2025 Refinancing Term Loan.
In connection with the issuance of the 2025 Refinancing Term Loan, the Company incurred $0.8 million of debt issuance costs.
Senior Notes
On August 26, 2024, the Company issued $600.0 million aggregate principal amount of 6.875% senior unsecured notes (the "2024 Notes") that mature in August 2032. Interest on the 2024 Notes is payable semiannually in February and August. In April 2021, the Company issued $400.0 million aggregate principal amount of 4.375% senior unsecured notes (the "2021 Notes", and together with the 2024 Notes, the "Senior Notes") that mature in April 2029. Interest on the 2021 Notes is payable semiannually in April and October. The Senior Notes are senior unsecured obligations of the Company and are guaranteed on a senior unsecured basis by each of the Company’s domestic subsidiaries that is a guarantor under our Credit Agreement. The terms of each indenture governing the Senior Notes, among other things, limit the ability of the Company and each of its subsidiaries to create liens on assets, enter into sale and leaseback transactions, and consolidate, merge or transfer all or substantially all of its assets and the assets of its subsidiaries. The terms of each indenture also limit the ability of the Company’s non-guarantor subsidiaries to incur certain types of debt.
The Company has the option to redeem all or a portion of the Senior Notes at redemption prices set forth in the applicable indenture, plus accrued and unpaid interest to the redemption date. If a Change of Control Triggering Event (as defined in each applicable indenture) occurs, the Company must offer to repurchase the Senior Notes at a price equal to 101% of the principal amount of the Senior Notes, plus accrued and unpaid interest to the date of repurchase.
The estimated fair values of the 2024 Notes and 2021 Notes as of September 30, 2025 were $627.1 million and $389.8 million, respectively, based on quoted market prices in a market with little activity (Level 2 input).
In connection with the issuance of the 2024 Notes and the 2021 Notes, the Company incurred $8.2 million and $6.6 million, respectively, of debt issuance costs.

Leases [Abstract]  
Leases Leases
We have various leases primarily for office space, land and buildings, and certain equipment. At inception, we determine if an arrangement contains a lease and whether that lease meets the classification criteria of a finance or operating lease. For leases that contain options to purchase, terminate, or extend, such options are included in the lease term when it is reasonably certain that the option will be exercised. Some of our lease arrangements contain lease components and non-lease components which are accounted for as a single lease component as we have elected the practical expedient to group lease and non-lease components for all leases.
As most of our leases do not provide an implicit rate, we use our incremental borrowing rate based on information available at commencement date in determining the present value of lease payments.
Future minimum lease payments for operating and finance lease obligations as of September 30, 2025 consisted of the following:

Income Taxes Income Taxes
For interim income tax reporting, we estimate our annual effective tax rate and apply it to our year-to-date ordinary income (loss). Tax jurisdictions with a projected or year to date loss for which a tax benefit cannot be realized are excluded. The tax effects of unusual or infrequently occurring items, including changes in judgment about valuation allowances and effects of changes in tax laws or rates, are reported in the interim period in which they occur. We have open tax years from 2019 to 2024 with various significant tax jurisdictions.
Our effective tax rates of 16.2% and 16.0% for the three and nine months ended September 30, 2025, respectively, differed from the U.S. federal statutory rate of 21.0% due to Advanced Manufacturing Production ("AMP") tax credits, state income taxes, statutory depletion deductions, compensation-related items, and other foreign adjustments. Our effective tax rates of 13.1% and 15.2% for the three and nine months ended September 30, 2024, respectively, differed from the U.S. federal statutory rate of 21.0% due to AMP tax credits, compensation-related items, state income taxes, statutory depletion deductions, and tax effects of foreign currency translations.
On July 4, 2025, the One Big Beautiful Bill Act (“OBBBA”) was enacted. The OBBBA includes significant provisions, such as the permanent extension of certain expiring provisions of the Tax Cuts and Jobs Act, the scaling back of, repeal of, and/or addition of stricter eligibility requirements for, several renewable-energy tax incentives, and the restoration of immediate deductibility of certain capital expenditures for tangible, depreciable personal property, and research and development expenditures. The legislation has multiple effective dates, with certain provisions effective in 2025 and others implemented through 2027. As of September 30, 2025, the Company’s tax provision includes the estimated effects of mandatory aspects of the OBBBA, the impact of which were not significant. We continue to assess the potential impacts of further tax planning elections allowed under the OBBBA.

Earnings Per Share [Abstract]  
Earnings per Common Share Earnings Per Common Share
Basic earnings per common share is computed by dividing net income remaining after allocation to participating unvested restricted shares by the weighted average number of basic common shares outstanding for the period. Except when the effect would be antidilutive, the calculation of diluted earnings per common share includes the weighted average net impact of nonparticipating unvested restricted shares. Total weighted average restricted shares were 0.9 million and 1.1 million for the three and nine months ended September 30, 2025, respectively. Total weighted average restricted shares were 1.1 million and 1.2 million for the three and nine months ended September 30, 2024, respectively.
The computation of basic and diluted earnings per share follows.

Commitments and Contingencies Commitments and Contingencies
The Company is involved in claims and lawsuits incidental to our business arising from various matters including commercial disputes, alleged product defect and/or warranty claims, intellectual property matters, personal injury claims, environmental issues, employment and/or workplace-related matters, and various governmental regulations. The Company evaluates its exposure to such claims and suits periodically and establishes accruals for these contingencies when probable losses can be reasonably estimated. At September 30, 2025, the reasonably possible losses and any related accruals for such matters were not significant.
Estimates of liability arising from future proceedings, assessments, or remediation are inherently imprecise. Accordingly, there can be no assurance that we will not become involved in future litigation or other proceedings, including those related to the environment or, if we are found to be responsible or liable in any such litigation or proceeding, that such costs would not be material to the Company.
Other commitments
In the normal course of business, at September 30, 2025, the Company was contingently liable for $206.3 million in surety bonds, which guarantee its own performance and are required by certain states and municipalities and their related agencies. The Company has indemnified the underwriting insurance companies against any exposure under the surety bonds. The Company is not aware of any circumstances that would result in material claims against these bonds.

Basis of Presentation
Basis of Presentation
Arcosa, Inc. and its consolidated subsidiaries (“Arcosa,” the “Company,” “we,” or “our”), headquartered in Dallas, Texas, is a provider of infrastructure-related products and solutions with leading brands serving construction, engineered structures, and transportation markets in North America. Arcosa is a Delaware corporation and was incorporated in 2018.
The accompanying Consolidated Financial Statements are unaudited and have been prepared from the books and records of Arcosa, Inc. and its consolidated subsidiaries. All normal and recurring adjustments necessary for a fair presentation of the financial position of the Company and the results of operations, comprehensive income/loss, and cash flows have been made in conformity with accounting principles generally accepted in the U.S. (“GAAP”). All significant intercompany accounts and transactions have been eliminated. Because of seasonal and other factors, the financial condition and results of operations for the three and nine months ended September 30, 2025 may not be indicative of Arcosa's expected business, financial condition, and results of operations for the year ending December 31, 2025.
These interim financial statements and notes are condensed as permitted by the instructions to Form 10-Q and should be read in conjunction with the audited Consolidated Financial Statements of the Company included in its Annual Report on Form 10-K for the year ended December 31, 2024.
Stockholders' Equity
Stockholders' Equity
In December 2024, the Company’s Board of Directors (the “Board") authorized a $50.0 million share repurchase program effective January 1, 2025 through December 31, 2026 to replace an expiring program of the same amount. For the three and nine months ended September 30, 2025, the Company did not repurchase any shares, leaving the full amount of the $50.0 million authorization available as of September 30, 2025.
Revenue Recognition
Revenue Recognition
Revenue is measured based on the allocation of the transaction price in a contract to satisfied performance obligations. The transaction price does not include any amounts collected on behalf of third parties. The Company recognizes revenue when it satisfies a performance obligation by transferring control over a product or service to a customer. The following is a description of principal activities from which the Company generates its revenue, separated by reportable segments. Payments for our products and services are generally due within normal commercial terms. For a further discussion regarding the Company’s reportable segments, see Note 4 Segment Information.
Construction Products
The Construction Products segment primarily recognizes revenue when the customer has accepted the product and legal title of the product has passed to the customer.
Engineered Structures
Within the Engineered Structures segment, revenue is recognized for wind towers and certain utility structures over time as the products are manufactured using an input approach based on the costs incurred relative to the total estimated costs of production. We recognize revenue over time for these products as they are highly customized to the needs of an individual customer resulting in no alternative use to the Company if not purchased by the customer after the contract is executed. In addition, we have the right to bill the customer for our work performed to date plus at least a reasonable profit margin for work performed. As of September 30, 2025, we had a contract asset of $78.6 million related to these contracts, compared to $65.5 million as of December 31, 2024, which is included in receivables, net of allowance, within the Consolidated Balance Sheets. The increase in the contract asset is attributed to timing of deliveries of finished structures to customers during the period. For all other products, revenue is recognized when the customer has accepted the product and legal title of the product has passed to the customer.
Transportation Products
The Transportation Products segment recognizes revenue when the customer has accepted the product and legal title of the product has passed to the customer.

Total revenues for the Company's reportable segments are presented below:

Unsatisfied Performance Obligations
The following table includes estimated revenue expected to be recognized in future periods related to performance obligations that are unsatisfied or partially satisfied as of September 30, 2025:

Engineered Structures:
Utility and related structures$461.5 
Wind towers$526.3 
Transportation Products:

In our Engineered Structures segment, 43% of the unsatisfied performance obligations for our utility and related structures are expected to be recognized during 2025, and substantially all of the remaining performance obligations are expected to be recognized in 2026. For our wind towers business, 18% of the unsatisfied performance obligations are expected to be recognized during 2025, with the remainder expected to be recognized through 2027.
For inland barges in our Transportation Products segment, 30% of the unsatisfied performance obligations are expected to be recognized during 2025, and the remainder are expected to be recognized in 2026.
Income Tax
Income Taxes
The liability method is used to account for income taxes. Deferred income taxes represent the tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. Valuation allowances reduce deferred tax assets to an amount that will more likely than not be realized.
The Company regularly evaluates the likelihood of realization of tax benefits derived from positions it has taken in various federal and state filings after consideration of all relevant facts, circumstances, and available information. For those tax positions that are deemed more likely than not to be sustained, the Company recognizes the benefit it believes is cumulatively greater than 50% likely to be realized. To the extent the Company were to prevail in matters for which accruals have been established or be required to pay amounts in excess of recorded reserves, the effective tax rate in a given financial statement period could be materially impacted.
Cash and Cash Equivalents
Financial Instruments
The Company considers all highly liquid debt instruments to be cash and cash equivalents if purchased with a maturity of three months or less.
Concentration of Credit Risk Financial instruments that potentially subject the Company to a concentration of credit risk are primarily cash investments and receivables. The Company places its cash investments in bank deposits and highly-rated money market funds, and its investment policy limits the amount of credit exposure to any one commercial issuer. We seek to limit concentration of credit risk with respect to the Company's receivables with control procedures that monitor the credit worthiness of customers, together with the large number of customers in the Company's customer base and their dispersion across different industries and geographic areas. As receivables are generally unsecured, the Company maintains an allowance based upon the expected credit losses. Receivable balances determined to be uncollectible are charged against the allowance. To accelerate the conversion to cash, the Company may sell a portion of its trade receivables to third parties. The Company has no recourse to these receivables once they are sold but may have continuing involvement related to servicing and collection activities. The impact of these transactions in the Company's Consolidated Statements of Operations for the three and nine months ended September 30, 2025 was not significant. The carrying values of cash, receivables, and accounts payable are considered to be representative of their respective fair values.
Recent Accounting Pronouncements
Recent Accounting Pronouncements
Recently adopted accounting pronouncements
Effective January 1, 2025, the Company adopted Accounting Standards Update No. 2023-09, “Income Taxes (Topic 740): Improvements to Income Tax Disclosures” (“ASU 2023-09”), which is intended to improve the transparency of income tax disclosures by requiring 1) consistent categories and greater disaggregation of information in the rate reconciliation and 2) income taxes paid disaggregated by jurisdiction. The standard also includes certain other amendments to improve the effectiveness of income tax disclosures. The additional disclosure requirements will be reflected in our Annual Report on Form 10-K for the year ending December 31, 2025. As ASU 2023-09 only modifies the Company's required income tax disclosures, the adoption of this guidance did not have a material impact on the Company's Consolidated Financial Statements.
Effective January 1, 2024, the Company adopted Accounting Standards Update No. 2023-07, “Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures” (“ASU 2023-07”), which is intended to improve reportable segment disclosure requirements, primarily through enhanced disclosures about significant segment expenses. The adoption of this guidance did not have a material effect on the Company's Consolidated Financial Statements.
Recently issued accounting pronouncements not adopted as of September 30, 2025
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 public business entities to disclose additional information about certain key expense categories within major income statement captions in the notes to consolidated financial statements. These enhanced disclosures are expected to help investors more effectively understand an entity's performance, assess its prospects for future cash flows, and compare an entity's performance over time and with that of other entities. ASU 2024-03 is effective for annual reporting periods beginning after December 15, 2026, and interim reporting periods beginning after December 15, 2027, and may be applied either prospectively or retrospectively. Early adoption is permitted. The Company is currently evaluating the impact of adopting ASU 2024-03 on its Consolidated Financial Statements.
