Accounting Policies [Abstract]  
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 present our historical financial position, results of operations, comprehensive income/loss, and cash flows in accordance with accounting principles generally accepted in the U.S. (“GAAP”). All significant intercompany accounts and transactions have been eliminated.
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 year ended December 31, 2025, the Company did not repurchase any shares, leaving the full amount of the $50.0 million authorization available as of December 31, 2025. Under the previous program, the Company did not repurchase any shares during the year ended December 31, 2024, and repurchased 200,000 shares at a cost of $13.8 million during the year ended December 31, 2023.
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 December 31, 2025 and 2024, we had a contract asset of $65.1 million and $65.5 million, respectively, which is included in receivables, net of allowance, within the Consolidated Balance Sheets. The decrease in the contract asset is attributed to the 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, 95% of the unsatisfied performance obligations for our utility and related structures are expected to be recognized during 2026, and all of the remaining performance obligations are expected to be recognized during 2027. For our wind towers business, 42% of the unsatisfied performance obligations are expected to be recognized during 2026, 53% are expected to be recognized during 2027, and the remainder are expected to be recognized during 2028.
For inland barges in our Transportation Products segment, all of the unsatisfied performance obligations are expected to be recognized during 2026.
Advance Billings
Advance billings represent cash collected from customers prior to the satisfaction of the related performance obligations and are separately presented on the Consolidated Balance Sheets. For the years ended December 31, 2025, 2024 and 2023, the Company recognized as revenue substantially all of the advance billings balances that were outstanding at the beginning of each respective year.
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 years ended December 31, 2025, 2024, and 2023 was not significant. The carrying values of cash, receivables, and accounts payable are considered to be representative of their respective fair values.
Inventories
Inventories are valued at the lower of cost or net realizable value. Cost is determined principally on the first in first out method. The value of inventory is adjusted for damaged, obsolete, excess, or slow-moving inventory. Work in process and finished goods include material, labor, and overhead.
Property, Plant, and Equipment
Property, plant, and equipment are stated at cost and depreciated or depleted over their estimated useful lives, primarily using the straight-line method. The estimated useful lives are: buildings and improvements - 5 to 30 years; leasehold improvements - the lesser of the term of the lease or 15 years; and machinery and equipment - 3 to 15 years. Depletion of mineral reserves is calculated based on estimated reserves using the units-of-production method on a quarry-by-quarry basis. The costs of ordinary maintenance and repair are charged to operating costs as incurred.
Goodwill and Intangible Assets
Goodwill is required to be tested for impairment annually, or on an interim basis when events or changes in circumstances indicate the carrying amount might be impaired. The quantitative goodwill impairment test is assessed at the “reporting unit” level by comparing the reporting unit's estimated fair value with the carrying amount of its net assets. If the carrying value of the reporting unit exceeds its fair value, an impairment loss is recognized. The goodwill impairment is measured as the excess of the reporting unit's carrying value over its fair value, not to exceed the amount of goodwill allocated to the reporting unit. The estimates and judgments that most significantly affect the fair value calculations are assumptions, consisting of level three inputs, related to revenue and operating profit growth and discount rates. The Company performs its annual goodwill impairment analysis as of October 1 of each year. As of October 1, 2025 and 2024, the Company's annual impairment test of goodwill was completed at the reporting unit level and no impairment charges were determined to be necessary.
Intangible assets are recorded at fair value, using level three inputs, on the date of acquisition and evaluated to determine their estimated useful life. These assets primarily consist of customer relationships and permits and are amortized using the straight-line method. The estimated useful lives for definite-lived intangible assets are: customer relationships - 5 to 20 years; permits - 10 to 29 years; and other - 5 to 34 years.
Indefinite-lived intangible assets primarily relate to acquired trademarks. These assets are not amortized but are evaluated for impairment annually on October 1, or on an interim basis when events or changes in circumstances indicate the carrying amount may not be recoverable. The impairment test compares the fair value of each asset to its carrying value using a relief from royalty method. As of October 1, 2025 and 2024, the Company's annual impairment test was completed and no impairment charges were determined to be necessary.
Long-lived Assets
The Company evaluates the carrying value of long-lived assets to be held and used, including property, plant, and equipment and definite-lived intangibles, for potential impairment when events or changes in circumstances indicate the carrying amount may not be recoverable. The carrying value of long-lived assets to be held and used is considered impaired only when the carrying value is not recoverable through undiscounted future cash flows and the fair value of the assets is less than their carrying value. Fair value is determined primarily using the anticipated cash flows discounted at a rate commensurate with the risks involved or market quotes as available. Impairment losses on long-lived assets held for sale are determined in a similar manner, except that fair values are reduced by the estimated cost to dispose of the assets. See Note 5. "Property, Plant, and Equipment".
Workers’ Compensation
The Company is effectively self-insured for workers’ compensation claims. A third-party administrator is used to process claims. We accrue our workers' compensation liability based upon independent actuarial studies. As of December 31, 2025 and 2024, the Company's accrual for worker's compensation costs was $19.4 million and $18.9 million, respectively, which is included in accrued liabilities and other long-term liabilities within the Consolidated Balance Sheets.
Warranties
The Company provides various express, limited product warranties that generally range from 1 to 5 years depending on the product. The warranty costs are estimated using a two-step approach. First, an engineering estimate is made for the cost of all claims that have been asserted by customers. Second, based on historical, accepted claims experience, a cost is accrued for all products still within a warranty period for which no claims have been filed. The Company provides for the estimated cost of product warranties at the time revenue is recognized related to products covered by warranties and assesses the adequacy of the resulting reserves on a quarterly basis. As of December 31, 2025 and 2024, the Company's accrual for warranty costs was not significant and is included in accrued liabilities within the Consolidated Balance Sheets.
Derivative Instruments
The Company may, from time to time, use derivative instruments to mitigate the impact of changes in interest rates, commodity prices, or changes in foreign currency exchange rates. For derivative instruments designated as hedges, the Company formally documents the relationship between the derivative instrument and the hedged item, as well as the risk management objective and strategy for the use of the derivative instrument. This documentation includes linking the derivative to specific assets or liabilities on the balance sheet, commitments, or forecasted transactions. At the time a derivative instrument is entered into, and at least quarterly thereafter, the Company assesses whether the derivative instrument is effective in offsetting the changes in fair value or cash flows of the hedged item. Any change in the fair value of the hedged instrument is recorded in accumulated other comprehensive loss (“AOCL”) as a separate component of stockholders' equity and reclassified into earnings in the period during which the hedged transaction affects earnings. The Company monitors its derivative positions and the credit ratings of its counterparties and does not anticipate losses due to counterparties' non-performance.
Foreign Currency Translation
Certain operations outside the U.S. prepare financial statements in currencies other than the U.S. dollar. The income statement amounts are translated at average exchange rates for the year, while the assets and liabilities are translated at year-end exchange rates. Translation adjustments are accumulated as a separate component of stockholders' equity and other comprehensive income (loss). The functional currency of our Mexico operations is considered to be the U.S. dollar. The functional currency of our Canadian operations is considered to be the Canadian dollar. For the years ended December 31, 2025, 2024 and 2023, foreign currency exchange transactions, included in other nonoperating (income) expense in the Consolidated Statements of Operations, were not significant.
Other Comprehensive Income (Loss)
Other comprehensive income (loss) consists of foreign currency translation adjustments and the effective unrealized gains and losses on the Company's derivative financial instruments, the sum of which, along with net income, constitutes comprehensive net income (loss). See Note 11. "Accumulated Other Comprehensive Loss". All components are shown net of tax.
Other Operating (Income) Expense
Other operating (income) expense consists of impairment charges and gains or losses on disposition of assets and sale of businesses. See Note 2. "Acquisitions and Divestitures" and Note 5. "Property, Plant, and Equipment".
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 Company adopted the additional disclosure requirements prospectively within its annual reporting 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.
Recently issued accounting pronouncements not adopted as of December 31, 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.
Management's 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 disclosure of contingent assets and liabilities at the date of the financial statements as well as the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.
Reclassifications
Certain prior year balances have been reclassified in the Consolidated Financial Statements and accompanying notes to the Consolidated Financial Statements to conform with the current year presentation.

Goodwill recorded, net$(12.3)$397.1 $40.4 
2025 Acquisitions
There were no acquisitions completed during the year ended December 31, 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 year ended December 31, 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:

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.
Revenues and operating profit included in the Consolidated Statement of Operations from the date of the Stavola acquisition were approximately $78.2 million and $4.5 million, respectively, for the year ended December 31, 2024. Non-recurring transaction costs included during the year ended December 31, 2024 were $25.5 million. The costs are included in selling, general, and administrative expenses in the Consolidated Statement of Operations. Additionally, the Company incurred $6.2 million of debt issuance costs during the year ended December 31, 2024 for commitments on a bridge loan facility that was not drawn upon and terminated upon placement of the long term financing to fund the Stavola acquisition. This non-recurring cost is included in interest expense on the Consolidated Statement of Operations.
The following table represents the unaudited pro-forma consolidated operating results of the Company as if the Stavola acquisition had been completed on January 1, 2023 and includes adjustments to:
•Include additional depreciation, depletion, and amortization expense related to the fair value of acquired property, plant, and equipment, mineral reserves, and intangible assets.
•Include the impact to cost of sales from the sell-through of inventory that was stepped up in value.
•Exclude transaction costs of $25.5 million from the year ended December 31, 2024 and reflect such expenses in the year ended December 31, 2023.
•Include additional interest expense related to debt financing transactions.
The unaudited pro-forma information should not be considered indicative of the results that would have occurred if the acquisition had been completed on January 1, 2023, nor is such unaudited pro-forma information necessarily indicative of future results.

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.
2023 Acquisitions
In December 2023, we completed the acquisition of certain assets and liabilities of Lake Point Holdings, LLC and Lake Point Restoration LLC, (collectively "Lake Point") a Florida based natural aggregates business in our Construction Products segment, for a total purchase price of $65.1 million. The acquisition was funded with $60.0 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, $13.3 million of property, plant, and equipment, $19.1 million of mineral reserves, $11.5 million of permits, and $15.6 million of goodwill in our Construction Products segment.
In October 2023, we completed the acquisition of certain assets and liabilities of a Florida based recycled aggregates business and a Phoenix, Arizona based recycled aggregates business, both of which are included in our Construction Products segment. The purchase prices of these acquisitions were not significant.
In September 2023, we completed the acquisition of certain assets and liabilities of a Houston, Texas based stabilized sand producer in our Construction Products segment. The purchase price of the acquisition was not significant.
In March 2023, we completed the stock acquisition of a Houston, Texas based shoring, trench, and excavation products business in our Construction Products segment. In February 2023, we completed the acquisition of certain assets and liabilities of a Phoenix, Arizona based recycled aggregates business in our Construction Products segment. The purchase prices of these acquisitions were not significant.
Divestitures
There were no divestitures completed during the year ended December 31, 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 December 31, 2025 was $2.2 million. See Note 3. "Fair Value Accounting". During the year ended December 31, 2025, the Company recognized a loss of $14.7 million, primarily due to a change in the estimated fair value of the earnout and certain long-term liabilities, which is presented within other operating income on the Consolidated Statements of Operations. During the year ended December 31, 2024, the Company recognized a loss of $21.6 million on the sale of the business, which is presented within other operating income on the Consolidated Statement of Operations. Revenues and operating profit (loss) of the steel components business were $87.8 million and $(19.5) million, respectively, for the year ended December 31, 2024, and $153.3 million and $11.0 million, respectively, for the year end December 31, 2023. 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 either from a quantitative or qualitative perspective. As such, 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. The Company recognized a net pre-tax gain of $12.5 million which is reflected in other operating income on the Consolidated Statement of Operations.
There were no divestitures completed during the year ended December 31, 2023.
Divestitures - Subsequent Event
On February 24, 2026, the Company entered into a Stock Purchase Agreement to sell its barge business to an affiliate of Wynnchurch Capital, L.P., for a cash purchase price of approximately $450 million, subject to customary purchase price adjustments. The barge business is a leading manufacturer of inland barges, fiberglass barge covers, winches, and marine hardware with operations located along the U.S. inland river systems. Reported within the Transportation Products segment, revenues and operating profit of the barge business were $383.3 million and $60.8 million, respectively, during the year ended December 31, 2025, and $329.8 million and $49.7 million, respectively, during the year ended December 31, 2024. The divestiture is expected to close in the second quarter of 2026 and is subject to regulatory approval and other customary closing conditions. The transaction is expected to generate a pre-tax gain and the Company intends to use the after-tax proceeds to further invest in the expansion of its core growth platforms and reduce outstanding debt.
Other
In June 2023, the Company settled a $15.0 million holdback obligation from the 2021 acquisition of Southwest Rock upon the extension of a certain mineral reserve lease. Based on final negotiations with the seller, the holdback obligation was settled for $10.0 million and paid in June 2023. The $5.0 million difference between the settlement amount and the amount accrued at the time of acquisition was recorded as a reduction in cost of revenues in the Consolidated Statement of Operations.

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 4.50 to 1.00 for the year ended December 31, 2025 and 4.00 to 1.00 during the first quarter of 2026, and 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 December 31, 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 December 31, 2025, the margin for borrowing based on SOFR was set at 1.75% and the commitment fee rate was set at 0.30%.
The revolving credit facility portion of the Credit Agreement requires the maintenance of certain ratios related to leverage and interest coverage. As of December 31, 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 December 31, 2025, total unamortized debt issuance costs related to the prior and amended revolving credit facilities were $2.7 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 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. 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 year ended December 31, 2025, without premium or penalty, the Company prepaid $156.5 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 December 31, 2025 were $632.9 million and $393.5 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.
The remaining principal payments under existing debt agreements as of December 31, 2025 are as follows:

Interest rate hedges
In December 2018, the Company entered into a $100.0 million interest rate swap instrument, effective as of January 2, 2019, to reduce the effect of changes in the variable interest rates associated with the first $100.0 million of borrowings under the Company's committed credit facility. In conjunction with the replacement of LIBOR with SOFR as a benchmark for borrowings under our credit facility, on July 1, 2023 the swap instrument transitioned from LIBOR to SOFR. The instrument effectively fixed the SOFR component of borrowings under our credit facility at a monthly rate of 2.71% until such instrument's termination. The interest rate swap instrument expired in October 2023.

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 December 31, 2025 consisted of the following:

On August 16, 2022, the Inflation Reduction Act of 2022 (“IRA”) was enacted. Among other things, the IRA provides for certain manufacturing, production, and investment tax credit incentives, including new Advanced Manufacturing Production ("AMP") tax credits for companies that domestically manufacture and sell clean energy equipment, including wind towers. For the years ended December 31, 2025, 2024 and 2023, the Company has recognized $72.8 million, $53.6 million and $32.4 million, respectively, in gross AMP tax credits for wind towers produced and sold which are included as a reduction to cost of revenues on the Consolidated Statement of Operations due to the refundable nature of the credits. During the year ended December 31, 2025, the Company sold $67.1 million and $8.3 million of the 2025 and 2024 AMP tax credits, respectively. In the year ended December 31, 2024, the Company sold $45.0 million of the 2024 AMP tax credits. All sales were completed pursuant to Section 6418 of the Internal Revenue Code resulting in losses of $5.1 million and $2.7 million, in 2025 and 2024, respectively, which are reflected in cost of revenues on the Consolidated Statements of Operations. The Company did not sell AMP tax credits in 2023. The Company has utilized $3.8 million of the credits to offset the US federal income tax liability in 2025 and a remaining $11.1 million of AMP tax credits are included in deferred tax assets on the Consolidated Balance Sheet as of December 31, 2025.
The Organization for Economic Co-operation and Development issued Pillar Two model rules for a global minimum tax of 15% effective January 1, 2024 ("Pillar Two"). While it is uncertain whether the U.S. will enact legislation to adopt Pillar Two, certain countries in which we operate have adopted legislation, and other countries are in the process of introducing legislation to implement Pillar Two. Pillar Two had no impact on our 2025 or 2024 tax rates, and we do not currently expect Pillar Two to significantly impact our tax rate going forward.
Income (loss) before income taxes for the years ended December 31, 2025, 2024, and 2023 was $236.0 million, $130.9 million, and $182.6 million, respectively, for U.S. operations, and $5.3 million, $(0.9) million, and $13.3 million, respectively, for foreign operations, principally Mexico and Canada. The Company provides deferred income taxes on the unrepatriated earnings of its foreign operations that are not considered permanently reinvested where it results in a deferred tax liability.
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. The components of deferred tax liabilities and assets are as follows:

At December 31, 2025, the Company had $10.3 million of federal net operating loss carryforwards, primarily from businesses acquired, that will begin to expire in the year 2036, and had $5.0 million of tax-effected state loss carryforwards that will begin to expire in 2033. In addition, at December 31, 2025, the Company had $10.5 million of tax-effected foreign net operating loss carryforwards that will begin to expire in the year 2026.
We have established a valuation allowance for state and foreign tax operating losses and credits that we have estimated may not be realizable.
Income tax has not been recognized on the excess of the amount for financial reporting over the tax basis of investments in foreign subsidiaries that is indefinitely reinvested outside the U.S. This amount becomes taxable upon a repatriation of assets from the subsidiary or a sale or liquidation of the subsidiary. Determination of the amount of any unrecognized deferred income tax liability on this temporary difference is not practicable because of the hypothetical calculation.
Taxing authority examinations
We have multiple federal tax return filings that are subject to examination by the Internal Revenue Service. The 2022-2024 tax years are open for the Arcosa, Inc. federal return. We have various subsidiaries that file separate state tax returns and are subject to examination by taxing authorities at different times, generally open for their 2021 tax years and forward. We have various subsidiaries in Mexico that file separate tax returns and are subject to examination by taxing authorities at different times. The entities are generally open for their 2019 tax years and forward.
Unrecognized tax benefits
Unrecognized tax benefits represent the differences between tax positions taken or expected to be taken on a tax return and the benefits recognized for financial statement purposes. There were no unrecognized tax benefits as of December 31, 2025, 2024, and 2023.
The Company accounts for interest expense and penalties related to income tax issues as income tax expense. Accordingly, interest expense and penalties associated with an uncertain tax position are included in the income tax provision. There were no accrued interest and penalties as of December 31, 2025, 2024, and 2023.

Defined Contribution Plans
Established under Internal Revenue Code Section 401(k), the Arcosa, Inc. 401(k) Plan (“401(k) Plan”) is a defined contribution plan available to all eligible employees. Participants in the 401(k) Plan are eligible to receive future retirement benefits through elected contributions, a company-funded match and certain eligible employees also receive an annual company-funded contribution. The investment of all funds are directed by the participants.
The Company also sponsors a fully‑funded, non-qualified deferred compensation plan. The invested assets and related liabilities of these participants were approximately $7.0 million at December 31, 2025 and December 31, 2024, which are included in other assets and other liabilities on the Consolidated Balance Sheets. Distributions from the Company’s non-qualified deferred compensation plan to participants were approximately $3.0 million for the year ended December 31, 2025 and $1.6 million for the year ended December 31, 2024.
Multiemployer Plans
The Company contributes to various multiemployer defined benefit pension plans under the terms of collective-bargaining agreements that cover certain union-represented employees at one of the facilities in our Engineered Structures segment and four of the facilities in our Construction Products segment acquired in the Stavola acquisition. The risks of participating in a multiemployer plan are different from a single-employer plan in the following aspects:
•Assets contributed to a multiemployer plan by one employer may be used to provide benefits to employees of other participating employers.
•If a participating employer stops contributing to a multiemployer plan, the unfunded obligations of the plan may be borne by the remaining participating employers.
•If the Company chooses to stop participating in the multiemployer plan, the Company may be required to pay the plan an amount based on the underfunded status of the plan, referred to as a withdrawal liability.
Our participation in multiemployer plans for the year ended December 31, 2025 are outlined in the table below. The Pension Protection Act (“PPA”) zone status is based upon the most recent information available at December 31, 2025 and 2024 and is obtained from the multiemployer plan's regulatory filings available in the public domain and certified by the plan's actuary. Among other factors, plans in the green zone are at least 80% funded, plans in the yellow zone are less than 80% funded, and plans in the red zone are less than 65% funded. Federal law requires that plans classified in the yellow or red zones adopt a funding improvement plan or a rehabilitation plan in order to improve the financial health of the plan. The Company's contributions to the multiemployer plans were less than 5% of total contributions to any plan. The last column in the table lists the expiration date of the last expiring collective bargaining agreement to which the plan is subject.

At December 31, 2025, we had 1.2 million shares available for grant. Any equity awards that have been granted under the Plan that are subsequently forfeited, canceled, or tendered to satisfy tax withholding obligations are added back to the shares available for grant.
The cost of employee services received in exchange for awards of equity instruments is referred to as share-based payments and is based on the grant date fair-value of those awards. Stock-based compensation includes compensation expense, recognized over the applicable vesting periods, for share-based awards. As a result of the spin-off of Arcosa from Trinity Industries, Inc ("Trinity") in 2018, certain Arcosa employees continue to hold restricted shares or units in Trinity common stock. The Company recognizes compensation expense for both the Arcosa awards and the Trinity awards held by our employees. Stock-based compensation totaled $26.4 million, $24.3 million, and $23.9 million for the years ended December 31, 2025, 2024, and 2023, respectively.
The income tax benefit related to stock-based compensation expense was $6.4 million, $6.9 million, and $6.8 million for the years ended December 31, 2025, 2024, and 2023, respectively.
Equity Awards
Equity awards outstanding as of December 31, 2025 consist of restricted stock, restricted stock units, and performance units and generally vest for periods ranging from 1 to 15 years from the date of grant. Certain equity awards vest in their entirety or on a pro-rata basis upon the employee's retirement from the Company and may take into consideration the employee's age and years of service to the Company, as defined more specifically in the Company's award agreements. Equity awards granted to non-employee directors under the Plan generally vest one year from the grant date. At that time, restricted stock is released immediately and restricted stock units are released at the earlier of five years after the vesting date or upon completion of the directors' service to the Company. Expense related to equity awards issued to eligible employees and directors under the Plan is recognized ratably over the vesting period or to the date on which retirement eligibility is achieved, if shorter. Performance units vest and settle in shares of our common stock following the end of a three-year performance period contingent upon the achievement of specific performance goals during the performance period and certification by the Human Resources Committee of the Board of the achievement of the performance goals. Performance units are granted to employees based upon a target level of performance; however, depending upon the achievement of the performance goals during the performance period, performance units may be issued at an amount between 0% and 200% of the target level. Expense related to performance units is recognized ratably over the vesting period. Forfeitures are recognized as reduction to expense in the period in which they occur.
The activity for equity awards held by Arcosa employees for the year ended December 31, 2025 was as follows:

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 1.0 million shares, 1.2 million shares, and 1.3 million shares, for the years ended December 31, 2025, 2024, and 2023, 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 December 31, 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
Non-cancelable purchase obligations amounted to $222.1 million as of December 31, 2025, of which $170.4 million is for the purchase of raw materials and components, primarily by the Engineered Structures and Transportation Products segments.
In the normal course of business, at December 31, 2025, the Company was contingently liable for $198.0 million in surety bonds, which guarantee the Company's 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.

Accounting Policies [Abstract]  
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 present our historical financial position, results of operations, comprehensive income/loss, and cash flows in accordance with accounting principles generally accepted in the U.S. (“GAAP”). All significant intercompany accounts and transactions have been eliminated.
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 year ended December 31, 2025, the Company did not repurchase any shares, leaving the full amount of the $50.0 million authorization available as of December 31, 2025. Under the previous program, the Company did not repurchase any shares during the year ended December 31, 2024, and repurchased 200,000 shares at a cost of $13.8 million during the year ended December 31, 2023.
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 December 31, 2025 and 2024, we had a contract asset of $65.1 million and $65.5 million, respectively, which is included in receivables, net of allowance, within the Consolidated Balance Sheets. The decrease in the contract asset is attributed to the 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 millions)
Engineered Structures:
Utility and related structures$434.9 
Wind towers$627.8 
Transportation Products:

In our Engineered Structures segment, 95% of the unsatisfied performance obligations for our utility and related structures are expected to be recognized during 2026, and all of the remaining performance obligations are expected to be recognized during 2027. For our wind towers business, 42% of the unsatisfied performance obligations are expected to be recognized during 2026, 53% are expected to be recognized during 2027, and the remainder are expected to be recognized during 2028.
For inland barges in our Transportation Products segment, all of the unsatisfied performance obligations are expected to be recognized during 2026.
Advance Billings
Advance billings represent cash collected from customers prior to the satisfaction of the related performance obligations and are separately presented on the Consolidated Balance Sheets. For the years ended December 31, 2025, 2024 and 2023, the Company recognized as revenue substantially all of the advance billings balances that were outstanding at the beginning of each respective year.
Income Taxes
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, 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.
Financial Instruments, 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 years ended December 31, 2025, 2024, and 2023 was not significant. The carrying values of cash, receivables, and accounts payable are considered to be representative of their respective fair values.
Inventories
Inventories
Inventories are valued at the lower of cost or net realizable value. Cost is determined principally on the first in first out method. The value of inventory is adjusted for damaged, obsolete, excess, or slow-moving inventory. Work in process and finished goods include material, labor, and overhead.
Property, Plant, and Equipment
Property, Plant, and Equipment
Property, plant, and equipment are stated at cost and depreciated or depleted over their estimated useful lives, primarily using the straight-line method. The estimated useful lives are: buildings and improvements - 5 to 30 years; leasehold improvements - the lesser of the term of the lease or 15 years; and machinery and equipment - 3 to 15 years. Depletion of mineral reserves is calculated based on estimated reserves using the units-of-production method on a quarry-by-quarry basis. The costs of ordinary maintenance and repair are charged to operating costs as incurred.
Goodwill and Intangible Assets
Goodwill and Intangible Assets
Goodwill is required to be tested for impairment annually, or on an interim basis when events or changes in circumstances indicate the carrying amount might be impaired. The quantitative goodwill impairment test is assessed at the “reporting unit” level by comparing the reporting unit's estimated fair value with the carrying amount of its net assets. If the carrying value of the reporting unit exceeds its fair value, an impairment loss is recognized. The goodwill impairment is measured as the excess of the reporting unit's carrying value over its fair value, not to exceed the amount of goodwill allocated to the reporting unit. The estimates and judgments that most significantly affect the fair value calculations are assumptions, consisting of level three inputs, related to revenue and operating profit growth and discount rates. The Company performs its annual goodwill impairment analysis as of October 1 of each year. As of October 1, 2025 and 2024, the Company's annual impairment test of goodwill was completed at the reporting unit level and no impairment charges were determined to be necessary.
Intangible assets are recorded at fair value, using level three inputs, on the date of acquisition and evaluated to determine their estimated useful life. These assets primarily consist of customer relationships and permits and are amortized using the straight-line method. The estimated useful lives for definite-lived intangible assets are: customer relationships - 5 to 20 years; permits - 10 to 29 years; and other - 5 to 34 years.
Indefinite-lived intangible assets primarily relate to acquired trademarks. These assets are not amortized but are evaluated for impairment annually on October 1, or on an interim basis when events or changes in circumstances indicate the carrying amount may not be recoverable. The impairment test compares the fair value of each asset to its carrying value using a relief from royalty method. As of October 1, 2025 and 2024, the Company's annual impairment test was completed and no impairment charges were determined to be necessary.
Long-lived Assets
Long-lived Assets
The Company evaluates the carrying value of long-lived assets to be held and used, including property, plant, and equipment and definite-lived intangibles, for potential impairment when events or changes in circumstances indicate the carrying amount may not be recoverable. The carrying value of long-lived assets to be held and used is considered impaired only when the carrying value is not recoverable through undiscounted future cash flows and the fair value of the assets is less than their carrying value. Fair value is determined primarily using the anticipated cash flows discounted at a rate commensurate with the risks involved or market quotes as available. Impairment losses on long-lived assets held for sale are determined in a similar manner, except that fair values are reduced by the estimated cost to dispose of the assets. See Note 5. "Property, Plant, and Equipment".
Workers' Compensation
Workers’ Compensation
The Company is effectively self-insured for workers’ compensation claims. A third-party administrator is used to process claims. We accrue our workers' compensation liability based upon independent actuarial studies. As of December 31, 2025 and 2024, the Company's accrual for worker's compensation costs was $19.4 million and $18.9 million, respectively, which is included in accrued liabilities and other long-term liabilities within the Consolidated Balance Sheets.
Warranties
Warranties
The Company provides various express, limited product warranties that generally range from 1 to 5 years depending on the product. The warranty costs are estimated using a two-step approach. First, an engineering estimate is made for the cost of all claims that have been asserted by customers. Second, based on historical, accepted claims experience, a cost is accrued for all products still within a warranty period for which no claims have been filed. The Company provides for the estimated cost of product warranties at the time revenue is recognized related to products covered by warranties and assesses the adequacy of the resulting reserves on a quarterly basis. As of December 31, 2025 and 2024, the Company's accrual for warranty costs was not significant and is included in accrued liabilities within the Consolidated Balance Sheets.
Derivative Instruments
Derivative Instruments
The Company may, from time to time, use derivative instruments to mitigate the impact of changes in interest rates, commodity prices, or changes in foreign currency exchange rates. For derivative instruments designated as hedges, the Company formally documents the relationship between the derivative instrument and the hedged item, as well as the risk management objective and strategy for the use of the derivative instrument. This documentation includes linking the derivative to specific assets or liabilities on the balance sheet, commitments, or forecasted transactions. At the time a derivative instrument is entered into, and at least quarterly thereafter, the Company assesses whether the derivative instrument is effective in offsetting the changes in fair value or cash flows of the hedged item. Any change in the fair value of the hedged instrument is recorded in accumulated other comprehensive loss (“AOCL”) as a separate component of stockholders' equity and reclassified into earnings in the period during which the hedged transaction affects earnings. The Company monitors its derivative positions and the credit ratings of its counterparties and does not anticipate losses due to counterparties' non-performance.
Foreign Currency Translation
Foreign Currency Translation
Certain operations outside the U.S. prepare financial statements in currencies other than the U.S. dollar. The income statement amounts are translated at average exchange rates for the year, while the assets and liabilities are translated at year-end exchange rates. Translation adjustments are accumulated as a separate component of stockholders' equity and other comprehensive income (loss). The functional currency of our Mexico operations is considered to be the U.S. dollar. The functional currency of our Canadian operations is considered to be the Canadian dollar. For the years ended December 31, 2025, 2024 and 2023, foreign currency exchange transactions, included in other nonoperating (income) expense in the Consolidated Statements of Operations, were not significant.
Other Comprehensive Income (Loss)
Other Comprehensive Income (Loss)
Other comprehensive income (loss) consists of foreign currency translation adjustments and the effective unrealized gains and losses on the Company's derivative financial instruments, the sum of which, along with net income, constitutes comprehensive net income (loss). See Note 11. "Accumulated Other Comprehensive Loss". All components are shown net of tax.
Other Operating (Income) Expense
Other Operating (Income) Expense
Other operating (income) expense consists of impairment charges and gains or losses on disposition of assets and sale of businesses. See Note 2. "Acquisitions and Divestitures" and Note 5. "Property, Plant, and Equipment".
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 Company adopted the additional disclosure requirements prospectively within its annual reporting 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.
Recently issued accounting pronouncements not adopted as of December 31, 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.
Management's Estimates
Management's 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 disclosure of contingent assets and liabilities at the date of the financial statements as well as the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.
Reclassifications
Reclassifications
Certain prior year balances have been reclassified in the Consolidated Financial Statements and accompanying notes to the Consolidated Financial Statements to conform with the current year presentation.

Our participation in multiemployer plans for the year ended December 31, 2025 are outlined in the table below. The Pension Protection Act (“PPA”) zone status is based upon the most recent information available at December 31, 2025 and 2024 and is obtained from the multiemployer plan's regulatory filings available in the public domain and certified by the plan's actuary. Among other factors, plans in the green zone are at least 80% funded, plans in the yellow zone are less than 80% funded, and plans in the red zone are less than 65% funded. Federal law requires that plans classified in the yellow or red zones adopt a funding improvement plan or a rehabilitation plan in order to improve the financial health of the plan. The Company's contributions to the multiemployer plans were less than 5% of total contributions to any plan. The last column in the table lists the expiration date of the last expiring collective bargaining agreement to which the plan is subject.
