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. Revenues 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 December 31, 2025:
| Unsatisfied performance obligations at |  |
| December 31, 2025 |  |
| Total Amount |  |  |  |
| (in millions) |  |  |  |
Engineered Structures: |  |  |  |  |
Utility and related structures | $ | 434.9 |  |  |  |  |
Wind towers | $ | 627.8 |  |  |  |  |
Transportation Products: |  |  |  |  |
Inland barges | $ | 296.9 |  |  |  |  |
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.
