Notes to Consolidated Financial Statements

(unaudited)

Note 1. 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 as a publicly-traded company, listed on the New York Stock Exchange.

The accompanying Consolidated Financial Statements are unaudited and have been prepared from the books and records of Arcosa, Inc. and its consolidated subsidiaries. All normal and recurring adjustments necessary for a fair presentation of the financial position of the Company and the results of operations, comprehensive income/loss, and cash flows have been made in conformity with accounting principles generally accepted in the U.S. (“GAAP”). All significant intercompany accounts and transactions have been eliminated. Because of seasonal and other factors, the financial condition and results of operations for the three and six months ended June 30, 2025 may not be indicative of Arcosa's expected business, financial condition, and results of operations for the year ending December 31, 2025.

These interim financial statements and notes are condensed as permitted by the instructions to Form 10-Q and should be read in conjunction with the audited Consolidated Financial Statements of the Company included in its Annual Report on Form 10-K for the year ended December 31, 2024.

Stockholders' Equity

In December 2024, the Company’s Board of Directors (the “Board") authorized a $50.0 million share repurchase program effective January 1, 2025 through December 31, 2026 to replace an expiring program of the same amount. For the three and six months ended June 30, 2025, the Company did not repurchase any shares, leaving the full amount of the $50.0 million authorization available as of June 30, 2025.

Revenue Recognition

Revenue is measured based on the allocation of the transaction price in a contract to satisfied performance obligations. The transaction price does not include any amounts collected on behalf of third parties. The Company recognizes revenue when it satisfies a performance obligation by transferring control over a product or service to a customer. The following is a description of principal activities from which the Company generates its revenue, separated by reportable segments. Payments for our products and services are generally due within normal commercial terms. For a further discussion regarding the Company’s reportable segments, see Note 4 Segment Information.

Construction Products

The Construction Products segment primarily recognizes revenue when the customer has accepted the product and legal title of the product has passed to the customer.

Engineered Structures

Within the Engineered Structures segment, revenue is recognized for wind towers and certain utility structures over time as the products are manufactured using an input approach based on the costs incurred relative to the total estimated costs of production. We recognize revenue over time for these products as they are highly customized to the needs of an individual customer resulting in no alternative use to the Company if not purchased by the customer after the contract is executed. In addition, we have the right to bill the customer for our work performed to date plus at least a reasonable profit margin for work performed. As of June 30, 2025, we had a contract asset of $57.6 million related to these contracts, compared to $65.5 million as of December 31, 2024, which is included in receivables, net of allowance, within the Consolidated Balance Sheets. The decrease in the contract asset is attributed to timing of deliveries of finished structures to customers during the period. For all other products, revenue is recognized when the customer has accepted the product and legal title of the product has passed to the customer.

Transportation Products

The Transportation Products segment recognizes revenue when the customer has accepted the product and legal title of the product has passed to the customer.

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

(1) On August 16, 2024, the Company completed the divestiture of its steel components business.

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 June 30, 2025:

	Unsatisfied performance obligations as of  June 30, 2025
	Total Amount
	(in millions)
Engineered Structures:
Utility and related structures	$	450.0
Wind towers	$	598.6
Transportation Products:
Inland barges	$	277.0

In our Engineered Structures segment, 84% of the unsatisfied performance obligations for our utility and related structures are expected to be delivered during 2025, and substantially all of the remaining performance obligations are expected to be delivered in 2026. For our wind towers business, 30% are expected to be delivered during 2025, 24% are expected to be delivered during 2026, and the remainder are expected to be delivered through 2028.

For inland barges in our Transportation Products segment, 57% of the unsatisfied performance obligations are expected to be delivered during 2025, and the remainder are expected to be delivered in 2026.

Income Taxes

The liability method is used to account for income taxes. Deferred income taxes represent the tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. Valuation allowances reduce deferred tax assets to an amount that will more likely than not be realized.

The Company regularly evaluates the likelihood of realization of tax benefits derived from positions it has taken in various federal and state filings after consideration of all relevant facts, circumstances, and available information. For those tax positions that are deemed more likely than not to be sustained, the Company recognizes the benefit it believes is cumulatively greater than 50% likely to be realized. To the extent the Company were to prevail in matters for which accruals have been established or be required to pay amounts in excess of recorded reserves, the effective tax rate in a given financial statement period could be materially impacted.

Financial Instruments

The Company considers all highly liquid debt instruments to be cash and cash equivalents if purchased with a maturity of three months or less. Financial instruments that potentially subject the Company to a concentration of credit risk are primarily cash investments and receivables. The Company places its cash investments in bank deposits and highly-rated money market funds, and its investment policy limits the amount of credit exposure to any one commercial issuer. We seek to limit concentration of credit risk with respect to the Company's receivables with control procedures that monitor the credit worthiness of customers, together with the large number of customers in the Company's customer base and their dispersion across different industries and geographic areas. As receivables are generally unsecured, the Company maintains an allowance based upon the expected credit losses. Receivable balances determined to be uncollectible are charged against the allowance. To accelerate the conversion to cash, the Company may sell a portion of its trade receivables to third parties. The Company has no recourse to these receivables once they are sold but may have continuing involvement related to servicing and collection activities. The impact of these transactions in the Company's Consolidated Statements of Operations for the three and six months ended June 30, 2025 was not significant. The carrying values of cash, receivables, and accounts payable are considered to be representative of their respective fair values.

Recent Accounting Pronouncements

Recently adopted accounting pronouncements

Effective January 1, 2025, the Company adopted Accounting Standards Update No. 2023-09, “Income Taxes (Topic 740): Improvements to Income Tax Disclosures” (“ASU 2023-09”), which is intended to improve the transparency of income tax disclosures by requiring 1) consistent categories and greater disaggregation of information in the rate reconciliation and 2) income taxes paid disaggregated by jurisdiction. The standard also includes certain other amendments to improve the effectiveness of income tax disclosures. The additional disclosure requirements will be reflected in our Annual Report on Form 10-K for the year ending December 31, 2025. As ASU 2023-09 only modifies the Company's required income tax disclosures, the adoption of this guidance did not have a material impact on the Company's Consolidated Financial Statements.

Effective January 1, 2024, the Company adopted Accounting Standards Update No. 2023-07, “Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures” (“ASU 2023-07”), which is intended to improve reportable segment disclosure requirements, primarily through enhanced disclosures about significant segment expenses. The adoption of this guidance did not have a material effect on the Company's Consolidated Financial Statements.

Recently issued accounting pronouncements not adopted as of June 30, 2025

In November 2024, the FASB issued Accounting Standards Update No. 2024-03. "Income Statement-Reporting Comprehensive Income-Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses" ("ASU 2024-03"), which requires public business entities to disclose additional information about certain key expense categories within major income statement captions in the notes to consolidated financial statements. These enhanced disclosures are expected to help investors more effectively understand an entity's performance, assess its prospects for future cash flows, and compare an entity's performance over time and with that of other entities. ASU 2024-03 is effective for annual reporting periods beginning after December 15, 2026, and interim reporting periods beginning after December 15, 2027, and may be applied either prospectively or retrospectively. Early adoption is permitted. The Company is currently evaluating the impact of adopting ASU 2024-03 on its Consolidated Financial Statements.

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.

Note 2. Acquisitions and Divestitures

2025 Acquisitions

There were no acquisitions completed during the three and six months ended June 30, 2025.

2024 Acquisitions

On October 1, 2024, we acquired substantially all of the construction materials business of Stavola Holding Corporation and its affiliated entities ("Stavola") for $1.2 billion in cash, subject to certain customary purchase price adjustments. The purchase price was funded with a combination of proceeds from a private offering of $600.0 million of 6.875% senior unsecured notes that closed on August 26, 2024 and $700.0 million in borrowings under a variable-rate secured term loan entered into on October 1, 2024. See Note 7 Debt for additional information. Stavola, which is included in our Construction Products segment, is an aggregates-led and vertically integrated construction materials company primarily serving the New York-New Jersey Metropolitan Statistical Area ("MSA") through its network of five hard rock natural aggregates quarries, twelve asphalt plants, and three recycled aggregates sites. The Stavola acquisition expanded our platform into the nation's largest MSA with industry-leading financial attributes. During the three months ended March 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. There were no amounts received from escrow during the three months ended June 30, 2025.

The Stavola acquisition was recorded as a business combination based on a preliminary 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). We expect to complete our purchase price allocation as soon as reasonably possible, not to exceed one year from the acquisition date. Adjustments to the preliminary purchase price allocation could be material, particularly with respect to our preliminary estimates of property, plant, and equipment, including mineral reserves. The following table details the preliminary purchase price allocation as of the acquisition date:

	(in millions)
Cash	$	0.7
Receivables, net of allowance	69.2
Inventories	23.5
Other current assets	2.6
Property, plant, and equipment, including mineral reserves	743.0

Goodwill represents the excess of the purchase consideration over the preliminary valuation of the net assets acquired. The acquired goodwill, which has been assigned to the Construction Products segment, is tax-deductible and primarily attributable to Stavola's market position and existing workforce. The acquired intangibles include beneficial use rights, recycling permits, and the Stavola trade name, which have a useful life of 34 years, 20 years, and 5 years, respectively.

On the acquisition date, the Company also entered into three separate lease agreements for properties owned by the sellers. These lease agreements were accounted for separately from the Stavola acquisition, and the corresponding right of use assets and lease liabilities of $12.4 million and $12.6 million, respectively, are reflected in the Consolidated Balance Sheet as of June 30, 2025.

Revenues and operating profit included in the Consolidated Statement of Operations were $90.3 million and $22.9 million, respectively, for the three months ended June 30, 2025, and $116.7 million and $11.9 million, respectively, for the six months ended June 30, 2025. Non-recurring transaction costs incurred during the three and six months ended June 30, 2025 were $0.5 million and $1.2 million, respectively.

In July 2024, we completed the acquisition of a Phoenix, Arizona based natural aggregates business in our Construction Products segment, for a total purchase price of $35.0 million.

In April 2024, we completed the acquisition of Ameron Pole Products LLC ("Ameron"), a leading manufacturer of highly engineered, premium concrete and steel poles for a broad range of infrastructure applications, including lighting, traffic, electric distribution, and small-cell telecom, for a total purchase price of $180.0 million. With operations in Alabama, California, and Oklahoma, Ameron is included in our Engineered Structures segment. The acquisition was funded with $160.0 million of borrowings under our revolving credit facility and cash on hand. The acquisition was recorded as a business combination based on a valuation of the assets acquired and liabilities assumed at their acquisition date fair value using Level 3 inputs. The final valuation resulted in the recognition of, among others, $60.8 million of property, plant, and equipment, $25.6 million of customer relationships, $18.1 million of inventory, $12.8 million of developed technology, $12.0 million of accounts receivable, $8.9 million of trademarks and $42.3 million of goodwill in our Engineered Structures segment. The acquired goodwill, which is tax-deductible, primarily relates to Ameron's market position and existing workforce.

Divestitures

There were no divestitures completed during the three and six months ended June 30, 2025.

In August 2024, the Company completed the divestiture of its steel components business. The steel components business, previously reported in the Transportation Products segment, was a leading supplier of railcar coupling devices, railcar axles, and circular forgings. The total consideration for the divestiture was $110.0 million consisting of $55.0 million in cash, a $25.0 million seller's note and a $30.0 million earnout, for which the estimated fair value as of June 30, 2025 was $12.8 million. See Note 3 Fair Value Accounting. During the three and six months ended June 30, 2025, the Company recognized a loss of $2.8 million and $2.5 million, respectively, primarily due to a change in the estimated fair value of the earnout, which is presented within operating profit in the Consolidated Statements of Operations. Revenues and operating profit of the steel components business were $38.1 million and $2.0 million, respectively, for the three months ended June 30, 2024, and $74.2 million and $4.5 million, respectively, for the six months ended June 30, 2024. As the steel components business was not core to Arcosa's long-term strategy, its divestiture was not considered a strategic shift that would have a major effect on the Company's operations or financial results from either a quantitative or qualitative perspective. Accordingly, it is not reported as a discontinued operation.

During the three months ended June 30, 2024, we completed the divestiture of certain assets and liabilities of a single-location asphalt and paving operation in our Construction Products segment and the sale of a non-operating facility in our Engineered Structures segment. The total consideration for these divestitures was $27.3 million.

Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for that asset or liability in an orderly transaction between market participants on the measurement date. An entity is required to establish a fair value hierarchy that maximizes the use of observable inputs and minimizes the use of unobservable inputs when measuring fair value. The three levels of inputs that may be used to measure fair values are listed below:

Level 1 – This level is defined as quoted prices in active markets for identical assets or liabilities. The Company’s cash equivalents are instruments of the U.S. Treasury or highly-rated money market mutual funds.

Level 2 – This level is defined as observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.

Level 3 – This level is defined as unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. Contingent consideration relates to estimated future payments expected from businesses previously acquired or sold. We estimate the fair value of the contingent consideration using a model appropriate for the structure of the contingent consideration, which may include discounted cash flow models, Monte Carlo simulations, or option pricing models. The fair values are sensitive to changes in the forecast of the performance metrics and in other metrics such as discount rates and volatility. The fair value is reassessed quarterly based on assumptions used in our latest projections. See further discussion in Note 2 Acquisitions and Divestitures.

Note 4. Segment Information

The Company's operating segments are identified on the basis of information that is reviewed by our chief operating decision maker, the Chief Executive Officer, to make decisions about resources to be allocated and assess its performance. The Company reports operating results in three principal business segments:

Construction Products. The Construction Products segment primarily produces and sells natural and recycled aggregates, specialty materials, asphalt mix, and construction site support equipment, including trench shields and shoring products.

13

Engineered Structures. The Engineered Structures segment primarily manufactures and sells steel and concrete structures for infrastructure businesses, including utility structures for electricity transmission and distribution, structural wind towers, traffic and lighting structures, and telecommunication structures. These products share similar manufacturing competencies and steel sourcing requirements and can be manufactured across our North American footprint.

Transportation Products. The Transportation Products segment primarily manufactures and sells inland barges, fiberglass barge covers, winches, marine hardware, and other transportation and industrial equipment. In August 2024, the Company completed the sale of its steel components business, which manufactured and sold steel components for railcars. See Note 2 Acquisitions and Divestitures.

The financial information for these segments is shown in the tables below. We operate principally in North America.

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.

17

On August 15, 2024, we entered into Amendment No. 1 to the Credit Agreement ("Amendment No. 1 to the Credit Agreement") to, among other things, (i) increase our revolving credit facility from $600.0 million to $700.0 million, (ii) collateralize the amended revolving credit facility with substantially all of our and our subsidiary guarantors' personal property (with certain exceptions), (iii) make the applicable margin for revolving borrowings, letters of credit and the commitment fee rate be based on our consolidated net leverage ratio (permitting up to $150.0 million of unrestricted cash to be netted from the calculation thereof), (iv) modify the margin for Secured Overnight Financing Rate ("SOFR")-based revolving borrowings and letters of credit to range from 1.25% to 2.50% per annum, (v) modify the margin for base rate revolving borrowings to range from 0.25% to 1.50%, (vi) modify the commitment fee that accrues on the unused portion of the revolving credit facility to range from 0.20% to 0.45%, and (vii) modify the maximum permitted leverage ratio to include a net debt concept (permitting up to $150.0 million of unrestricted cash to be netted from the calculation thereof), and to provide that such ratio shall be no greater than 5.00 to 1.00 during the fourth quarter of 2024 and the next two fiscal quarters, 4.50 to 1.00 for the next following two fiscal quarters, and 4.00 to 1.00 for each fiscal quarter thereafter (however, this maximum permitted leverage ratio may be increased to 4.50 to 1.00 for up to four fiscal quarters if a material acquisition is entered into). These amendments did not become effective until the closing of the Stavola acquisition on October 1, 2024. The amended revolving credit facility's maturity date of August 23, 2028 remains unchanged.

As of June 30, 2025, we had no outstanding loans borrowed under our revolving credit facility, which left $700.0 million available for borrowing.

The interest rates for revolving loans under the Credit Agreement are variable based on the daily simple or term SOFR, plus a 10-basis point credit spread adjustment, or an alternate base rate, in each case plus a margin for borrowing. A commitment fee accrues on the average daily unused portion of the revolving credit facility. The margin for revolving borrowings and commitment fee rate are determined based on the Company’s consolidated total net leverage ratio (as measured by a consolidated funded indebtedness, less the aggregate amount of unrestricted cash up to a maximum amount not to exceed $150.0 million, to consolidated EBITDA ratio). As of June 30, 2025, the margin for borrowing based on SOFR was set at 2.00% and the commitment fee rate was set at 0.35%.

The revolving credit facility portion of the Credit Agreement requires the maintenance of certain ratios related to leverage and interest coverage. As of June 30, 2025, we were in compliance with all such financial covenants. Borrowings under the Credit Agreement are guaranteed by certain domestic subsidiaries of the Company. On October 1, 2024, we collateralized our obligations under the Credit Agreement with substantially all of our and our subsidiary guarantors' personal property (with certain exceptions).

The carrying value of revolving borrowings under the Credit Agreement approximates fair value because the interest rate adjusts to the market interest rate (Level 3 input). See Note 3 Fair Value Accounting.

In connection with the Credit Agreement, the Company incurred debt issuance costs of approximately $1.9 million during the year ended December 31, 2024. As of June 30, 2025, total unamortized debt issuance costs related to the prior and amended revolving credit facilities were $3.2 million. These costs are included in other assets on the Consolidated Balance Sheet and are amortized into interest expense over the term of the Credit Agreement.

Term Loan

Amendment No. 1 to the Credit Agreement provided for a secured term loan facility (the “2024 Term Loan”) in an aggregate principal amount of $700.0 million. The 2024 Term Loan was funded on October 1, 2024 with the closing of the Stavola acquisition, of which $100.0 million was used to pay down the Company's revolving credit facility. The 2024 Term Loan required, among other things, (i) mandatory prepayments from excess cash flow on an annual basis, commencing with the fiscal year ending December 31, 2025, (ii) mandatory prepayments with proceeds of certain asset sales and debt issuances, and (iii) quarterly principal amortization payments in an amount equal to 0.25% of the 2024 Term Loan. The 2024 Term Loan had a maturity date of October 1, 2031. The interest rate for the 2024 Term Loan was based on SOFR plus 2.25% per year. The 2024 Term Loan was prepayable at any time without penalty. The 2024 Term Loan was guaranteed by the same subsidiaries of the Company that guarantee our revolving credit facility, and the 2024 Term Loan was secured on a pari passu basis with our revolving credit facility.

In connection with the issuance of the 2024 Term Loan, the Company incurred $7.0 million of debt issuance costs.

18

On June 17, 2025, we entered into Amendment No. 2 to the Credit Agreement to establish a new class of term loans (the "2025 Refinancing Term Loan") in an aggregate principal amount of $698.3 million. We used the 2025 Refinancing Term Loan's net proceeds, together with cash on hand, to satisfy the outstanding balance under the 2024 Term Loan. The interest rate for the 2025 Refinancing Term Loan is based on SOFR plus 2.00% per year, or an alternate base rate, plus 1.00% per year, a 0.25% per annum reduction from the 2024 Term Loan. If the 2025 Refinancing Term Loan is prepaid in connection with a repricing transaction or we effect any amendment to the Credit Agreement resulting in a repricing transaction, in either case within six months after the initial funding of the 2025 Refinancing Term Loan, there is a 1.00% premium on such prepaid amount or on the amount outstanding at the time such repricing transaction amendment becomes effective. Otherwise, the 2025 Refinancing Term Loan is prepayable at any time without premium or penalty (other than customary SOFR-related breakage costs). All other terms of the 2025 Refinancing Term Loan are the same as the 2024 Term Loan that was prepaid with the proceeds of the 2025 Refinancing Term Loan.

In connection with the issuance of the 2025 Refinancing Term Loan, the Company incurred $0.7 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 June 30, 2025 were $623.0 million and $387.1 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 June 30, 2025 are as follows:

	2025		2026		2027		2028		2029		Thereafter
	(in millions)

Note 8. 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.

Note 10. Income Taxes

For interim income tax reporting, we estimate our annual effective tax rate and apply it to our year-to-date ordinary income (loss). Tax jurisdictions with a projected or year to date loss for which a tax benefit cannot be realized are excluded. The tax effects of unusual or infrequently occurring items, including changes in judgment about valuation allowances and effects of changes in tax laws or rates, are reported in the interim period in which they occur. We have open tax years from 2019 to 2024 with various significant tax jurisdictions.

Our effective tax rates of 14.5% and 15.9% for the three and six months ended June 30, 2025, respectively, differed from the U.S. federal statutory rate of 21.0% due to Advanced Manufacturing Production ("AMP") tax credits, state income taxes, statutory depletion deductions, compensation-related items, and other foreign adjustments. Our effective tax rates of 14.3% and 15.6% for the three and six months ended June 30, 2024, respectively, differed from the U.S. federal statutory rate of 21.0% due to AMP tax credits, compensation-related items, state income taxes, statutory depletion deductions, and tax effects of foreign currency translations.

On July 4, 2025, the One Big Beautiful Bill Act (“OBBBA”) was enacted. The OBBBA includes significant provisions, such as the permanent extension of certain expiring provisions of the Tax Cuts and Jobs Act, the scaling back of, repeal of, and/or addition of stricter eligibility requirements for, several renewable-energy tax incentives, and the restoration of immediate deductibility of certain capital expenditures for tangible, depreciable personal property, and research and development expenditures. The legislation has multiple effective dates, with certain provisions effective in 2025 and others implemented through 2027. We are currently assessing the impact of the OBBBA on our consolidated financial statements.

Note 14. 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 1.1 million for the three and six months ended June 30, 2025. Total weighted average restricted shares were 1.2 million for the three and six months ended June 30, 2024.

The computation of basic and diluted earnings per share follows.

	Three Months Ended June 30, 2025					Three Months Ended June 30, 2024
	Income (Loss)		Average Shares	EPS		Income (Loss)		Average Shares	EPS

Note 15. 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 June 30, 2025, the reasonably possible losses and any related accruals for such matters were not significant.

Estimates of liability arising from future proceedings, assessments, or remediation are inherently imprecise. Accordingly, there can be no assurance that we will not become involved in future litigation or other proceedings, including those related to the environment or, if we are found to be responsible or liable in any such litigation or proceeding, that such costs would not be material to the Company.

Other commitments

In the normal course of business, at June 30, 2025, the Company was contingently liable for $201.7 million in surety bonds, which guarantee its own performance and are required by certain states and municipalities and their related agencies. The Company has indemnified the underwriting insurance companies against any exposure under the surety bonds. The Company is not aware of any circumstances that would result in material claims against these bonds.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations

Management’s Discussion and Analysis of Financial Condition and Results of Operations (“MD&A”) is intended to provide a reader of our financial statements with a narrative from the perspective of our management on our financial condition, results of operations, liquidity, and certain other factors that may affect our future results. Our MD&A is presented in the following sections:

•Company Overview

•Market Outlook

•Executive Overview

•Results of Operations

•Liquidity and Capital Resources

•Recent Accounting Pronouncements

•Forward-Looking Statements

Our MD&A should be read in conjunction with the Consolidated Financial Statements of Arcosa, Inc. and its consolidated subsidiaries (“Arcosa,” “Company,” “we,” or “our”) and related Notes in Part I, Item 1 of this Quarterly Report on Form 10-Q and the Consolidated Financial Statements and related Notes in Item 8, “Financial Statements and Supplementary Data”, of our Annual Report on Form 10-K for the year ended December 31, 2024 (“2024 Annual Report on Form 10-K”).

Company Overview

Arcosa, 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 as a publicly-traded company, listed on the New York Stock Exchange.

Market Outlook

•Within our Construction Products segment, market demand remains healthy overall when seasonal weather conditions have been normal, supported by increased infrastructure spending and private non-residential activity. The outlook for single-family residential housing continues to be impacted by higher interest rates and home affordability, which has negatively impacted volumes. We have been successful in managing inflationary cost pressures through proactive price increases.

•Within our Engineered Structures segment, our backlog as of June 30, 2025 provides good production visibility for the remainder of 2025. Our customers remain committed to taking delivery of these orders. In utility structures, order and inquiry activity continues to be healthy, as customers remain focused on grid hardening and reliability initiatives, along with increasing demand for electricity. In our wind towers business, the Inflation Reduction Act ("IRA"), which passed in August 2022, was a significant catalyst for order activity following its passage. The IRA included a long-term extension of the Production Tax Credit (“PTC”) for new wind farm projects and introduced new Advanced Manufacturing Production (“AMP”) tax credits for companies that domestically manufacture and sell clean energy equipment in the U.S. Shortly following the passage of the IRA, we received new wind tower orders of $1.1 billion for delivery through 2028, a large portion of which is supporting wind energy expansion projects in the Southwest. As a result, we opened a new plant in New Mexico and started delivering towers from this facility in the second quarter of 2024. Uncertainty around potential changes in energy policy with the current U.S. presidential administration tempered order activity. The OBBBA, which was enacted on July 4, 2025, includes several provisions that roll-back, phase out, repeal, and/or add stricter eligibility requirements for, several tax incentives applicable to wind and solar projects. The OBBBA terminates the IRA's AMP tax credits for wind towers sold after 2027. Also, under the OBBBA, wind farm projects that begin construction after July 4, 2026, and are not placed in service before the end of 2027, will not be eligible for the PTC. The pending expiration of these incentives may pull demand forward. Notwithstanding these developments, we remain confident that further investment in wind energy is needed to meet the load growth demands in the U.S., and we continue to have discussions with our customers about additional orders for 2026 and beyond. As of June 30, 2025, our remaining backlog for wind towers was $598.6 million.

24

•Within our Transportation Products segment, our backlog for inland barges as of June 30, 2025 was $277.0 million, up 10% from June 30, 2024. Our customers remain committed to taking delivery of these orders. Our barge business is recovering from cyclical lows resulting from the onset of the COVID-19 pandemic when order levels fell sharply due to high steel prices throughout 2022 and 2023. Over this time, customer inquiries have remained healthy, initially for dry barges and more recently for tank barges. Our backlog for tank barges extends deep into 2026. Both fleets continue to age as new builds have not kept pace with scrapping, which indicates future replacement demand. During the second quarter, we received orders of $33 million primarily for hopper barges. After quarter end, we received additional orders totaling $122 million, solidifying our 2025 production plans and extending our hopper barge backlog into 2026 as well.

Executive Overview

Recent Developments

In October 2024, the Company completed the acquisition of the construction materials business of Stavola Holding Corporation and its affiliated entities ("Stavola") for $1.2 billion in cash. Stavola, which is reported within the Construction Products segment, serves the New York-New Jersey MSA through its network of five hard rock natural aggregates quarries, twelve asphalt plants, and three recycled aggregates sites.

In August 2024, the Company completed the sale of its steel components business. Previously reported in the Transportation Products segment, the steel components business was a leading supplier of railcar coupling devices, railcar axles, and circular forgings. 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.

Financial Operations and Highlights

•Revenues for the three and six months ended June 30, 2025 increased by 10.9% and 8.4%, respectively, to $736.9 million and $1,368.9 million, respectively, from the same periods in 2024, due to higher revenues in Construction Products and Engineered Structures, partially offset by lower revenues in Transportation Products resulting from the divestiture of the steel components business.

•Operating profit for the three and six months ended June 30, 2025 increased by $27.6 million and $30.0 million, respectively, to $94.8 million and $150.6 million, respectively, from the same periods in 2024, primarily driven by higher operating profit in Construction Products and Engineered Structures, partially offset by a decrease in Transportation Products resulting from the divestiture of the steel components business.

•Selling, general, and administrative expenses decreased by 8.2% and 1.3% for the three and six months ended June 30, 2025, respectively, from the same periods in 2024. As a percentage of revenues, selling, general, and administrative expenses were 9.9% and 10.7% for the three and six months ended June 30, 2025, respectively, compared to 12.0% and 11.8% for the same periods in 2024, respectively.

•Interest expense for the three and six months ended June 30, 2025 totaled $28.5 million and $56.8 million, respectively, an increase of $17.1 million and $37.1 million, respectively, from the same periods in 2024, driven by the additional debt incurred to finance the Stavola acquisition.

•The effective tax rate for the three and six months ended June 30, 2025 was 14.5% and 15.9%, respectively, compared to 14.3% and 15.6%, respectively, for the same periods in 2024. See Note 10 Income Taxes to the Consolidated Financial Statements.

•Net income for the three and six months ended June 30, 2025 was $59.7 million and $83.3 million, respectively, compared to $45.6 million and $84.8 million, respectively, for the same periods in 2024.

Our Engineered Structures and Transportation Products segments operate in cyclical industries. Additionally, results in our Construction Products segment are affected by weather and seasonal fluctuations with the second and third quarters historically being the quarters with the highest revenues.

Three Months Ended June 30, 2025 versus Three Months Ended June 30, 2024

•Revenues increased 28.4% primarily due to the acquisition of Stavola which contributed $90.3 million to revenues during the quarter. Organic revenues in our construction materials businesses declined as higher pricing was offset by lower volumes, a decrease in freight revenue, and a reduction in revenue from operations divested in the prior year. Revenues in our trench shoring business decreased 7.6% primarily due to lower volumes and reduced steel prices.

•Cost of revenues increased 29.7% due to increased costs from the Stavola acquisition, including higher depreciation, depletion, and amortization expense. This was partially offset by a slight decrease in costs for our legacy businesses driven by lower organic volumes. As a percentage of revenues, cost of revenues increased to 76.2% in the current period, compared to 75.4% in the prior period.

•Selling, general, and administrative expenses increased 4.1% due to additional costs from Stavola partially offset by lower costs in our legacy businesses. Selling, general, and administrative expenses as a percentage of revenues was 8.5% in the current period, compared to 10.5% in the prior period.

•Operating profit increased 48.7% primarily due to the impact of the Stavola acquisition, which contributed $22.9 million in the current period. On an organic basis, operating profit decreased due to the decline in revenues and lower cost absorption.

•Depreciation, depletion, and amortization expense increased 42.2% primarily due to the acquisition of Stavola, including the fair market value write-up of long-lived assets.

29

Six Months Ended June 30, 2025 versus Six Months Ended June 30, 2024

•Revenues increased 17.1% primarily due to the acquisition of Stavola which contributed $116.7 million to revenues during the period. Organic revenues in our construction materials businesses declined as higher pricing was offset by lower volumes, a decrease in freight revenue, and a reduction in revenue from operations divested in the prior year. Revenues from our trench shoring business decreased 6.0% primarily due to lower volumes and reduced steel prices.

•Cost of revenues increased 19.8% primarily due to increased costs from the recently acquired businesses, including higher depreciation, depletion, and amortization expense. These costs were partially offset by lower costs in our legacy businesses driven by lower organic volumes. As a percentage of revenues, cost of revenues was 78.9% in the current period, compared to 77.1% in the prior period.

•Selling, general, and administrative expenses increased 7.7% due to additional costs from Stavola partially offset by lower costs in our legacy businesses. Selling, general, and administrative expenses as a percentage of revenues was 10.0% in the current period, compared to 10.8% in the prior period.

•Operating profit increased 12.8% primarily due to the impact of the Stavola acquisition, which contributed $11.9 million in the current period. On an organic basis, operating profit decreased roughly in line with the decrease in revenues.

•Depreciation, depletion, and amortization expense increased 35.1% primarily due to the acquisition of Stavola, including the fair market value write-up of long-lived assets.

Three Months Ended June 30, 2025 versus Three Months Ended June 30, 2024

•Revenues increased 6.6% primarily due to higher volumes from the new wind tower facility in New Mexico which delivered its first wind tower in the prior period. Revenues for utility and related structures decreased slightly as higher volumes and improved product mix were offset by lower steel prices.

•Cost of revenues increased 1.4% primarily due to higher wind tower volumes. Costs of revenues for utility structures declined as lower steel costs more than offset increased volumes. As a percentage of revenues, cost of revenues decreased to 77.5% in the current period, compared to 81.5% in the prior period. This decrease is partially attributed to startup costs incurred in the prior period for the new wind tower facility.

•Selling, general, and administrative expenses decreased 2.5%. Selling, general, and administrative expenses as a percentage of revenues was 7.9% in the current period, compared to 8.7% in the prior period.

•During the prior period, the Company recognized a gain on the sale of a non-operating facility that previously supported the divested business.

•Operating profit increased 21.9% primarily due to higher wind tower volumes as well as increased volumes and operating improvements in our utility and related structures businesses, partially offset by the asset sale gains recognized in the prior period from the divested business.

Six Months Ended June 30, 2025 versus Six Months Ended June 30, 2024

•Revenues increased 14.1% primarily due to higher volumes from our new facility in our wind towers business. Revenue for our utility and related structures businesses increased slightly as higher utility structures volumes and the contribution from Ameron, which was acquired in April 2024, was partially offset by lower steel prices.

•Cost of revenues increased 7.6% primarily due to higher wind tower volumes. Costs of revenues for utility structures declined as lower steel costs more than offset increased volumes. As a percentage of revenues, cost of revenues decreased to 77.8% in the current period, compared to 82.5% in the prior period. This decrease is partially attributed to startup costs incurred in the prior period for the new wind tower facility.

•Selling, general, and administrative expenses increased 9.7% primarily due to additional costs from the acquired Ameron business.

•During the prior period, the Company recognized an additional gain related to the divestiture of the storage tanks business, which closed in October 2022, including a gain on the settlement of certain contingencies from the sale and a gain on the sale of a non-operating facility that previously supported the divested business.

•Operating profit increased 33.2% primarily due to higher wind tower volumes as well as increased volumes and operating improvements in our utility and related structures businesses, partially offset by the asset sale gains recognized in the prior period from the divested business.

Unsatisfied Performance Obligations (Backlog)

As of June 30, 2025, the backlog for utility and related structures was $450.0 million compared to $414.0 million and $424.6 million as of December 31, 2024 and June 30, 2024, respectively. We expect to deliver 84% of the unsatisfied performance obligations for utility and related structures during 2025, and substantially all of the remaining performance obligations are expected to be delivered in 2026.

The backlog for wind towers as of June 30, 2025 was $598.6 million compared to $776.8 million and $914.1 million as of December 31, 2024 and June 30, 2024, respectively. We expect to deliver 30% of the unsatisfied performance obligations for wind towers during 2025, 24% during 2026, with the remainder expected to be delivered through 2028.

Liquidity and Capital Resources

Arcosa’s primary liquidity requirement consists of funding our business operations, including operating expenses, capital expenditures, working capital investment, and our regular quarterly dividend. Our primary sources of liquidity include cash flow from operations, our existing cash balance, availability under the revolving credit facility, and, as necessary, the issuance of additional long-term debt or equity. We may also consider undertaking disciplined acquisitions, organic investment projects, additional return of capital to stockholders, or funding other general corporate purposes to the extent we have available liquidity.

Cash Flows

The following table summarizes our cash flows from operating, investing, and financing activities for the six months ended June 30, 2025 and 2024:

	Six Months Ended June 30,
	2025		2024
	(in millions)
Total cash provided (required) by:
Operating activities	$	60.5	$	118.8
Investing activities	(33.4)		(241.2)
Financing activities	(24.7)		121.3
Net increase (decrease) in cash and cash equivalents	$	2.4	$	(1.1)

Operating Activities. Net cash provided by operating activities for the six months ended June 30, 2025 was $60.5 million, compared to $118.8 million of net cash provided by operating activities for the six months ended June 30, 2024.

•The changes in current assets and liabilities resulted in a net use of cash of $156.3 million for the six months ended June 30, 2025, compared to a net use of cash of $44.7 million for the six months ended June 30, 2024. The current year activity was primarily driven by increases in receivables and inventory and a decrease in advanced billings, partially offset by higher accounts payable.

Investing Activities. Net cash required by investing activities for the six months ended June 30, 2025 was $33.4 million, compared to $241.2 million for the six months ended June 30, 2024.

•Capital expenditures for the six months ended June 30, 2025 were $61.8 million, compared to $102.0 million for the same period last year. Full-year capital expenditures are expected to be approximately $145 to $155 million in 2025.

•Proceeds from the sale of property, plant, and equipment and other assets totaled $10.8 million for the six months ended June 30, 2025, compared to $7.4 million for the same period in 2024.

•For the six months ended June 30, 2025, cash received from acquisitions was $17.6 million due to escrow funds that were returned to Arcosa related to contractual purchase price adjustments in connection with the Stavola acquisition. Cash paid for acquisitions, net of cash acquired, was $179.9 million during the same period in 2024.

•There were no proceeds from the sale of businesses during the six months ended June 30, 2025, compared to $33.3 million for the same period in 2024.

Other Investing and Financing Activities

Revolving Credit Facility, Term Loan, and Senior Notes

In August 2023, we entered into 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.

33

On August 15, 2024, we entered into 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 SOFR-based revolving borrowings and letters of credit to range from 1.25% to 2.50% per annum, (v) modify the margin for base rate revolving borrowings to range from 0.25% to 1.50%, (vi) modify the commitment fee that accrues on the unused portion of the revolving credit facility to range from 0.20% to 0.45%, and (vii) modify the maximum permitted leverage ratio to include a net debt concept (permitting up to $150.0 million of unrestricted cash to be netted from the calculation thereof), and to provide that such ratio shall be no greater than 5.00 to 1.00 during the fourth quarter of 2024 and the next two fiscal quarters, 4.50 to 1.00 for the next following two fiscal quarters, and 4.00 to 1.00 for each fiscal quarter thereafter (however, this maximum permitted leverage ratio may be increased to 4.50 to 1.00 for up to four fiscal quarters if a material acquisition is entered into). These amendments did not become effective until the closing of the Stavola acquisition on October 1, 2024. The amended revolving credit facility's maturity date of August 23, 2028 remains unchanged.

As of June 30, 2025, we had no outstanding loans borrowed under our revolving credit facility, which left $700.0 million available for borrowing.

The interest rates for revolving loans under the Credit Agreement are variable based on the daily simple or term SOFR, plus a 10-basis point credit spread adjustment, or an alternate base rate, in each case plus a margin for borrowing. A commitment fee accrues on the average daily unused portion of the revolving credit facility. The margin for revolving borrowings and commitment fee rate are determined based on the Company’s consolidated total net leverage ratio (as measured by a consolidated funded indebtedness, less the aggregate amount of unrestricted cash up to a maximum amount not to exceed $150.0 million, to consolidated EBITDA ratio). As of June 30, 2025, the margin for borrowing based on SOFR was set at 2.00% and the commitment fee rate was set at 0.35%.

The revolving credit facility portion of the Credit Agreement requires the maintenance of certain ratios related to leverage and interest coverage. As of June 30, 2025, we were in compliance with all such financial covenants. Borrowings under the Credit Agreement are guaranteed by certain domestic subsidiaries of the Company. On October 1, 2024, we collateralized our obligations under the Credit Agreement with substantially all of our and our subsidiary guarantors' personal property (with certain exceptions).

On June 17, 2025, we entered into Amendment No. 2 to the Credit Agreement, which established 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 2025 Refinancing Term Loan requires, 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 2025 Refinancing Term Loan has a maturity date of October 1, 2031. 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. If the 2025 Refinancing Term Loan is prepaid in connection with a repricing transaction or we effect any amendment to the Credit Agreement resulting in a repricing transaction, in either case within six months after the initial funding of the 2025 Refinancing Term Loan, there is a 1.0% premium on such prepaid amount or on the amount outstanding at the time such repricing transaction amendment becomes effective. Otherwise, the 2025 Refinancing Term Loan is prepayable at any time without premium or penalty (other than customary SOFR-related breakage costs). The 2025 Refinancing Term Loan is guaranteed by the same subsidiaries of the Company that guarantee our revolving credit facility, and the 2025 Refinancing Term Loan is secured on a pari passu basis with our revolving credit facility.

On August 26, 2024, the Company issued $600.0 million aggregate principal amount of 6.875% 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.

34

We believe, based on our current business plans, that our existing cash, available liquidity, and cash flow from operations will be sufficient to fund necessary capital expenditures and operating cash requirements for the foreseeable future.

Dividends and Repurchase Program

In May 2025, the Company declared a quarterly cash dividend of $0.05 per share that was paid on July 31, 2025.

In December 2024, the Board authorized a $50.0 million share repurchase program effective January 1, 2025 through December 31, 2026 to replace an expiring program of the same amount. For the three and six months ended June 30, 2025, the Company did not repurchase any shares, leaving the full amount of the $50.0 million authorization available as of June 30, 2025.

Accounting Policies [Abstract]

Overview and Summary of Significant Accounting Policies

Overview and Summary of Significant Accounting Policies

Basis of Presentation

Arcosa, Inc. and its consolidated subsidiaries (“Arcosa,” the “Company,” “we,” or “our”), headquartered in Dallas, Texas, is a provider of infrastructure-related products and solutions with leading brands serving construction, engineered structures, and transportation markets in North America. Arcosa is a Delaware corporation and was incorporated in 2018 as a publicly-traded company, listed on the New York Stock Exchange.

The accompanying Consolidated Financial Statements are unaudited and have been prepared from the books and records of Arcosa, Inc. and its consolidated subsidiaries. All normal and recurring adjustments necessary for a fair presentation of the financial position of the Company and the results of operations, comprehensive income/loss, and cash flows have been made in conformity with accounting principles generally accepted in the U.S. (“GAAP”). All significant intercompany accounts and transactions have been eliminated. Because of seasonal and other factors, the financial condition and results of operations for the three and six months ended June 30, 2025 may not be indicative of Arcosa's expected business, financial condition, and results of operations for the year ending December 31, 2025.

These interim financial statements and notes are condensed as permitted by the instructions to Form 10-Q and should be read in conjunction with the audited Consolidated Financial Statements of the Company included in its Annual Report on Form 10-K for the year ended December 31, 2024.

Stockholders' Equity

In December 2024, the Company’s Board of Directors (the “Board") authorized a $50.0 million share repurchase program effective January 1, 2025 through December 31, 2026 to replace an expiring program of the same amount. For the three and six months ended June 30, 2025, the Company did not repurchase any shares, leaving the full amount of the $50.0 million authorization available as of June 30, 2025.

Revenue Recognition

Revenue is measured based on the allocation of the transaction price in a contract to satisfied performance obligations. The transaction price does not include any amounts collected on behalf of third parties. The Company recognizes revenue when it satisfies a performance obligation by transferring control over a product or service to a customer. The following is a description of principal activities from which the Company generates its revenue, separated by reportable segments. Payments for our products and services are generally due within normal commercial terms. For a further discussion regarding the Company’s reportable segments, see Note 4 Segment Information.

Construction Products

The Construction Products segment primarily recognizes revenue when the customer has accepted the product and legal title of the product has passed to the customer.

Engineered Structures

Within the Engineered Structures segment, revenue is recognized for wind towers and certain utility structures over time as the products are manufactured using an input approach based on the costs incurred relative to the total estimated costs of production. We recognize revenue over time for these products as they are highly customized to the needs of an individual customer resulting in no alternative use to the Company if not purchased by the customer after the contract is executed. In addition, we have the right to bill the customer for our work performed to date plus at least a reasonable profit margin for work performed. As of June 30, 2025, we had a contract asset of $57.6 million related to these contracts, compared to $65.5 million as of December 31, 2024, which is included in receivables, net of allowance, within the Consolidated Balance Sheets. The decrease in the contract asset is attributed to timing of deliveries of finished structures to customers during the period. For all other products, revenue is recognized when the customer has accepted the product and legal title of the product has passed to the customer.

Transportation Products

The Transportation Products segment recognizes revenue when the customer has accepted the product and legal title of the product has passed to the customer.

Revenues

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

(1) On August 16, 2024, the Company completed the divestiture of its steel components business.

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 June 30, 2025:

	Unsatisfied performance obligations as of  June 30, 2025
	Total Amount
	(in millions)
Engineered Structures:
Utility and related structures	$	450.0
Wind towers	$	598.6
Transportation Products:
Inland barges	$	277.0

In our Engineered Structures segment, 84% of the unsatisfied performance obligations for our utility and related structures are expected to be delivered during 2025, and substantially all of the remaining performance obligations are expected to be delivered in 2026. For our wind towers business, 30% are expected to be delivered during 2025, 24% are expected to be delivered during 2026, and the remainder are expected to be delivered through 2028.

For inland barges in our Transportation Products segment, 57% of the unsatisfied performance obligations are expected to be delivered during 2025, and the remainder are expected to be delivered in 2026.

Income Taxes

The liability method is used to account for income taxes. Deferred income taxes represent the tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. Valuation allowances reduce deferred tax assets to an amount that will more likely than not be realized.

The Company regularly evaluates the likelihood of realization of tax benefits derived from positions it has taken in various federal and state filings after consideration of all relevant facts, circumstances, and available information. For those tax positions that are deemed more likely than not to be sustained, the Company recognizes the benefit it believes is cumulatively greater than 50% likely to be realized. To the extent the Company were to prevail in matters for which accruals have been established or be required to pay amounts in excess of recorded reserves, the effective tax rate in a given financial statement period could be materially impacted.

Financial Instruments

The Company considers all highly liquid debt instruments to be cash and cash equivalents if purchased with a maturity of three months or less. Financial instruments that potentially subject the Company to a concentration of credit risk are primarily cash investments and receivables. The Company places its cash investments in bank deposits and highly-rated money market funds, and its investment policy limits the amount of credit exposure to any one commercial issuer. We seek to limit concentration of credit risk with respect to the Company's receivables with control procedures that monitor the credit worthiness of customers, together with the large number of customers in the Company's customer base and their dispersion across different industries and geographic areas. As receivables are generally unsecured, the Company maintains an allowance based upon the expected credit losses. Receivable balances determined to be uncollectible are charged against the allowance. To accelerate the conversion to cash, the Company may sell a portion of its trade receivables to third parties. The Company has no recourse to these receivables once they are sold but may have continuing involvement related to servicing and collection activities. The impact of these transactions in the Company's Consolidated Statements of Operations for the three and six months ended June 30, 2025 was not significant. The carrying values of cash, receivables, and accounts payable are considered to be representative of their respective fair values.

Recent Accounting Pronouncements

Recently adopted accounting pronouncements

Effective January 1, 2025, the Company adopted Accounting Standards Update No. 2023-09, “Income Taxes (Topic 740): Improvements to Income Tax Disclosures” (“ASU 2023-09”), which is intended to improve the transparency of income tax disclosures by requiring 1) consistent categories and greater disaggregation of information in the rate reconciliation and 2) income taxes paid disaggregated by jurisdiction. The standard also includes certain other amendments to improve the effectiveness of income tax disclosures. The additional disclosure requirements will be reflected in our Annual Report on Form 10-K for the year ending December 31, 2025. As ASU 2023-09 only modifies the Company's required income tax disclosures, the adoption of this guidance did not have a material impact on the Company's Consolidated Financial Statements.

Effective January 1, 2024, the Company adopted Accounting Standards Update No. 2023-07, “Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures” (“ASU 2023-07”), which is intended to improve reportable segment disclosure requirements, primarily through enhanced disclosures about significant segment expenses. The adoption of this guidance did not have a material effect on the Company's Consolidated Financial Statements.

Recently issued accounting pronouncements not adopted as of June 30, 2025

In November 2024, the FASB issued Accounting Standards Update No. 2024-03. "Income Statement-Reporting Comprehensive Income-Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses" ("ASU 2024-03"), which requires public business entities to disclose additional information about certain key expense categories within major income statement captions in the notes to consolidated financial statements. These enhanced disclosures are expected to help investors more effectively understand an entity's performance, assess its prospects for future cash flows, and compare an entity's performance over time and with that of other entities. ASU 2024-03 is effective for annual reporting periods beginning after December 15, 2026, and interim reporting periods beginning after December 15, 2027, and may be applied either prospectively or retrospectively. Early adoption is permitted. The Company is currently evaluating the impact of adopting ASU 2024-03 on its Consolidated Financial Statements.

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.

Business Combination [Abstract]

Acquisitions and Divestitures

2025 Acquisitions

There were no acquisitions completed during the three and six months ended June 30, 2025.

2024 Acquisitions

On October 1, 2024, we acquired substantially all of the construction materials business of Stavola Holding Corporation and its affiliated entities ("Stavola") for $1.2 billion in cash, subject to certain customary purchase price adjustments. The purchase price was funded with a combination of proceeds from a private offering of $600.0 million of 6.875% senior unsecured notes that closed on August 26, 2024 and $700.0 million in borrowings under a variable-rate secured term loan entered into on October 1, 2024. See Note 7 Debt for additional information. Stavola, which is included in our Construction Products segment, is an aggregates-led and vertically integrated construction materials company primarily serving the New York-New Jersey Metropolitan Statistical Area ("MSA") through its network of five hard rock natural aggregates quarries, twelve asphalt plants, and three recycled aggregates sites. The Stavola acquisition expanded our platform into the nation's largest MSA with industry-leading financial attributes. During the three months ended March 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. There were no amounts received from escrow during the three months ended June 30, 2025.

The Stavola acquisition was recorded as a business combination based on a preliminary 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). We expect to complete our purchase price allocation as soon as reasonably possible, not to exceed one year from the acquisition date. Adjustments to the preliminary purchase price allocation could be material, particularly with respect to our preliminary estimates of property, plant, and equipment, including mineral reserves. The following table details the preliminary purchase price allocation as of the acquisition date:

	(in millions)
Cash	$	0.7
Receivables, net of allowance	69.2
Inventories	23.5
Other current assets	2.6
Property, plant, and equipment, including mineral reserves	743.0
Goodwill	333.8
Intangibles	41.0
Other assets	24.9
Accounts payable	(18.0)
Accrued liabilities	(2.6)
Advance billings	(0.8)
Other liabilities	(25.3)
Total net assets acquired	$	1,192.0

Goodwill represents the excess of the purchase consideration over the preliminary valuation of the net assets acquired. The acquired goodwill, which has been assigned to the Construction Products segment, is tax-deductible and primarily attributable to Stavola's market position and existing workforce. The acquired intangibles include beneficial use rights, recycling permits, and the Stavola trade name, which have a useful life of 34 years, 20 years, and 5 years, respectively.

On the acquisition date, the Company also entered into three separate lease agreements for properties owned by the sellers. These lease agreements were accounted for separately from the Stavola acquisition, and the corresponding right of use assets and lease liabilities of $12.4 million and $12.6 million, respectively, are reflected in the Consolidated Balance Sheet as of June 30, 2025.

Revenues and operating profit included in the Consolidated Statement of Operations were $90.3 million and $22.9 million, respectively, for the three months ended June 30, 2025, and $116.7 million and $11.9 million, respectively, for the six months ended June 30, 2025. Non-recurring transaction costs incurred during the three and six months ended June 30, 2025 were $0.5 million and $1.2 million, respectively.

In July 2024, we completed the acquisition of a Phoenix, Arizona based natural aggregates business in our Construction Products segment, for a total purchase price of $35.0 million.

In April 2024, we completed the acquisition of Ameron Pole Products LLC ("Ameron"), a leading manufacturer of highly engineered, premium concrete and steel poles for a broad range of infrastructure applications, including lighting, traffic, electric distribution, and small-cell telecom, for a total purchase price of $180.0 million. With operations in Alabama, California, and Oklahoma, Ameron is included in our Engineered Structures segment. The acquisition was funded with $160.0 million of borrowings under our revolving credit facility and cash on hand. The acquisition was recorded as a business combination based on a valuation of the assets acquired and liabilities assumed at their acquisition date fair value using Level 3 inputs. The final valuation resulted in the recognition of, among others, $60.8 million of property, plant, and equipment, $25.6 million of customer relationships, $18.1 million of inventory, $12.8 million of developed technology, $12.0 million of accounts receivable, $8.9 million of trademarks and $42.3 million of goodwill in our Engineered Structures segment. The acquired goodwill, which is tax-deductible, primarily relates to Ameron's market position and existing workforce.

Divestitures

There were no divestitures completed during the three and six months ended June 30, 2025.

In August 2024, the Company completed the divestiture of its steel components business. The steel components business, previously reported in the Transportation Products segment, was a leading supplier of railcar coupling devices, railcar axles, and circular forgings. The total consideration for the divestiture was $110.0 million consisting of $55.0 million in cash, a $25.0 million seller's note and a $30.0 million earnout, for which the estimated fair value as of June 30, 2025 was $12.8 million. See Note 3 Fair Value Accounting. During the three and six months ended June 30, 2025, the Company recognized a loss of $2.8 million and $2.5 million, respectively, primarily due to a change in the estimated fair value of the earnout, which is presented within operating profit in the Consolidated Statements of Operations. Revenues and operating profit of the steel components business were $38.1 million and $2.0 million, respectively, for the three months ended June 30, 2024, and $74.2 million and $4.5 million, respectively, for the six months ended June 30, 2024. As the steel components business was not core to Arcosa's long-term strategy, its divestiture was not considered a strategic shift that would have a major effect on the Company's operations or financial results from either a quantitative or qualitative perspective. Accordingly, it is not reported as a discontinued operation.

During the three months ended June 30, 2024, we completed the divestiture of certain assets and liabilities of a single-location asphalt and paving operation in our Construction Products segment and the sale of a non-operating facility in our Engineered Structures segment. The total consideration for these divestitures was $27.3 million.

Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for that asset or liability in an orderly transaction between market participants on the measurement date. An entity is required to establish a fair value hierarchy that maximizes the use of observable inputs and minimizes the use of unobservable inputs when measuring fair value. The three levels of inputs that may be used to measure fair values are listed below:

Level 1 – This level is defined as quoted prices in active markets for identical assets or liabilities. The Company’s cash equivalents are instruments of the U.S. Treasury or highly-rated money market mutual funds.

Level 2 – This level is defined as observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.

Level 3 – This level is defined as unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. Contingent consideration relates to estimated future payments expected from businesses previously acquired or sold. We estimate the fair value of the contingent consideration using a model appropriate for the structure of the contingent consideration, which may include discounted cash flow models, Monte Carlo simulations, or option pricing models. The fair values are sensitive to changes in the forecast of the performance metrics and in other metrics such as discount rates and volatility. The fair value is reassessed quarterly based on assumptions used in our latest projections. See further discussion in Note 2 Acquisitions and Divestitures.

Segment Reporting [Abstract]

Segment Information

Segment Information

The Company's operating segments are identified on the basis of information that is reviewed by our chief operating decision maker, the Chief Executive Officer, to make decisions about resources to be allocated and assess its performance. The Company reports operating results in three principal business segments:

Construction Products. The Construction Products segment primarily produces and sells natural and recycled aggregates, specialty materials, asphalt mix, and construction site support equipment, including trench shields and shoring products.

Engineered Structures. The Engineered Structures segment primarily manufactures and sells steel and concrete structures for infrastructure businesses, including utility structures for electricity transmission and distribution, structural wind towers, traffic and lighting structures, and telecommunication structures. These products share similar manufacturing competencies and steel sourcing requirements and can be manufactured across our North American footprint.

Transportation Products. The Transportation Products segment primarily manufactures and sells inland barges, fiberglass barge covers, winches, marine hardware, and other transportation and industrial equipment. In August 2024, the Company completed the sale of its steel components business, which manufactured and sold steel components for railcars. See Note 2 Acquisitions and Divestitures.

The financial information for these segments is shown in the tables below. We operate principally in North America.

Revolving Credit Facility

In August 2023, we entered into a Second Amended and Restated Credit Agreement (as amended, the "Credit Agreement") to increase our revolving credit facility from $500.0 million to $600.0 million, extend the maturity date of our revolving credit facility from January 2, 2025 to August 23, 2028, and refinance and repay in full the remaining balance of the term loan then outstanding under our prior credit facility.

On August 15, 2024, we entered into Amendment No. 1 to the Credit Agreement ("Amendment No. 1 to the Credit Agreement") to, among other things, (i) increase our revolving credit facility from $600.0 million to $700.0 million, (ii) collateralize the amended revolving credit facility with substantially all of our and our subsidiary guarantors' personal property (with certain exceptions), (iii) make the applicable margin for revolving borrowings, letters of credit and the commitment fee rate be based on our consolidated net leverage ratio (permitting up to $150.0 million of unrestricted cash to be netted from the calculation thereof), (iv) modify the margin for Secured Overnight Financing Rate ("SOFR")-based revolving borrowings and letters of credit to range from 1.25% to 2.50% per annum, (v) modify the margin for base rate revolving borrowings to range from 0.25% to 1.50%, (vi) modify the commitment fee that accrues on the unused portion of the revolving credit facility to range from 0.20% to 0.45%, and (vii) modify the maximum permitted leverage ratio to include a net debt concept (permitting up to $150.0 million of unrestricted cash to be netted from the calculation thereof), and to provide that such ratio shall be no greater than 5.00 to 1.00 during the fourth quarter of 2024 and the next two fiscal quarters, 4.50 to 1.00 for the next following two fiscal quarters, and 4.00 to 1.00 for each fiscal quarter thereafter (however, this maximum permitted leverage ratio may be increased to 4.50 to 1.00 for up to four fiscal quarters if a material acquisition is entered into). These amendments did not become effective until the closing of the Stavola acquisition on October 1, 2024. The amended revolving credit facility's maturity date of August 23, 2028 remains unchanged.

As of June 30, 2025, we had no outstanding loans borrowed under our revolving credit facility, which left $700.0 million available for borrowing.

The interest rates for revolving loans under the Credit Agreement are variable based on the daily simple or term SOFR, plus a 10-basis point credit spread adjustment, or an alternate base rate, in each case plus a margin for borrowing. A commitment fee accrues on the average daily unused portion of the revolving credit facility. The margin for revolving borrowings and commitment fee rate are determined based on the Company’s consolidated total net leverage ratio (as measured by a consolidated funded indebtedness, less the aggregate amount of unrestricted cash up to a maximum amount not to exceed $150.0 million, to consolidated EBITDA ratio). As of June 30, 2025, the margin for borrowing based on SOFR was set at 2.00% and the commitment fee rate was set at 0.35%.

The revolving credit facility portion of the Credit Agreement requires the maintenance of certain ratios related to leverage and interest coverage. As of June 30, 2025, we were in compliance with all such financial covenants. Borrowings under the Credit Agreement are guaranteed by certain domestic subsidiaries of the Company. On October 1, 2024, we collateralized our obligations under the Credit Agreement with substantially all of our and our subsidiary guarantors' personal property (with certain exceptions).

The carrying value of revolving borrowings under the Credit Agreement approximates fair value because the interest rate adjusts to the market interest rate (Level 3 input). See Note 3 Fair Value Accounting.

In connection with the Credit Agreement, the Company incurred debt issuance costs of approximately $1.9 million during the year ended December 31, 2024. As of June 30, 2025, total unamortized debt issuance costs related to the prior and amended revolving credit facilities were $3.2 million. These costs are included in other assets on the Consolidated Balance Sheet and are amortized into interest expense over the term of the Credit Agreement.

Term Loan

Amendment No. 1 to the Credit Agreement provided for a secured term loan facility (the “2024 Term Loan”) in an aggregate principal amount of $700.0 million. The 2024 Term Loan was funded on October 1, 2024 with the closing of the Stavola acquisition, of which $100.0 million was used to pay down the Company's revolving credit facility. The 2024 Term Loan required, among other things, (i) mandatory prepayments from excess cash flow on an annual basis, commencing with the fiscal year ending December 31, 2025, (ii) mandatory prepayments with proceeds of certain asset sales and debt issuances, and (iii) quarterly principal amortization payments in an amount equal to 0.25% of the 2024 Term Loan. The 2024 Term Loan had a maturity date of October 1, 2031. The interest rate for the 2024 Term Loan was based on SOFR plus 2.25% per year. The 2024 Term Loan was prepayable at any time without penalty. The 2024 Term Loan was guaranteed by the same subsidiaries of the Company that guarantee our revolving credit facility, and the 2024 Term Loan was secured on a pari passu basis with our revolving credit facility.

In connection with the issuance of the 2024 Term Loan, the Company incurred $7.0 million of debt issuance costs.

On June 17, 2025, we entered into Amendment No. 2 to the Credit Agreement to establish a new class of term loans (the "2025 Refinancing Term Loan") in an aggregate principal amount of $698.3 million. We used the 2025 Refinancing Term Loan's net proceeds, together with cash on hand, to satisfy the outstanding balance under the 2024 Term Loan. The interest rate for the 2025 Refinancing Term Loan is based on SOFR plus 2.00% per year, or an alternate base rate, plus 1.00% per year, a 0.25% per annum reduction from the 2024 Term Loan. If the 2025 Refinancing Term Loan is prepaid in connection with a repricing transaction or we effect any amendment to the Credit Agreement resulting in a repricing transaction, in either case within six months after the initial funding of the 2025 Refinancing Term Loan, there is a 1.00% premium on such prepaid amount or on the amount outstanding at the time such repricing transaction amendment becomes effective. Otherwise, the 2025 Refinancing Term Loan is prepayable at any time without premium or penalty (other than customary SOFR-related breakage costs). All other terms of the 2025 Refinancing Term Loan are the same as the 2024 Term Loan that was prepaid with the proceeds of the 2025 Refinancing Term Loan.

In connection with the issuance of the 2025 Refinancing Term Loan, the Company incurred $0.7 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 June 30, 2025 were $623.0 million and $387.1 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 June 30, 2025 are as follows:

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 June 30, 2025 consisted of the following:

	Operating Leases		Finance Leases
	(in millions)
2025 (remaining)	$	6.3	$	2.2

Income Taxes

For interim income tax reporting, we estimate our annual effective tax rate and apply it to our year-to-date ordinary income (loss). Tax jurisdictions with a projected or year to date loss for which a tax benefit cannot be realized are excluded. The tax effects of unusual or infrequently occurring items, including changes in judgment about valuation allowances and effects of changes in tax laws or rates, are reported in the interim period in which they occur. We have open tax years from 2019 to 2024 with various significant tax jurisdictions.

Our effective tax rates of 14.5% and 15.9% for the three and six months ended June 30, 2025, respectively, differed from the U.S. federal statutory rate of 21.0% due to Advanced Manufacturing Production ("AMP") tax credits, state income taxes, statutory depletion deductions, compensation-related items, and other foreign adjustments. Our effective tax rates of 14.3% and 15.6% for the three and six months ended June 30, 2024, respectively, differed from the U.S. federal statutory rate of 21.0% due to AMP tax credits, compensation-related items, state income taxes, statutory depletion deductions, and tax effects of foreign currency translations.

On July 4, 2025, the One Big Beautiful Bill Act (“OBBBA”) was enacted. The OBBBA includes significant provisions, such as the permanent extension of certain expiring provisions of the Tax Cuts and Jobs Act, the scaling back of, repeal of, and/or addition of stricter eligibility requirements for, several renewable-energy tax incentives, and the restoration of immediate deductibility of certain capital expenditures for tangible, depreciable personal property, and research and development expenditures. The legislation has multiple effective dates, with certain provisions effective in 2025 and others implemented through 2027. We are currently assessing the impact of the OBBBA on our consolidated financial statements.

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 1.1 million for the three and six months ended June 30, 2025. Total weighted average restricted shares were 1.2 million for the three and six months ended June 30, 2024.

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 June 30, 2025, the reasonably possible losses and any related accruals for such matters were not significant.

Estimates of liability arising from future proceedings, assessments, or remediation are inherently imprecise. Accordingly, there can be no assurance that we will not become involved in future litigation or other proceedings, including those related to the environment or, if we are found to be responsible or liable in any such litigation or proceeding, that such costs would not be material to the Company.

Other commitments

In the normal course of business, at June 30, 2025, the Company was contingently liable for $201.7 million in surety bonds, which guarantee its own performance and are required by certain states and municipalities and their related agencies. The Company has indemnified the underwriting insurance companies against any exposure under the surety bonds. The Company is not aware of any circumstances that would result in material claims against these bonds.

These interim financial statements and notes are condensed as permitted by the instructions to Form 10-Q and should be read in conjunction with the audited Consolidated Financial Statements of the Company included in its Annual Report on Form 10-K for the year ended December 31, 2024.

Stockholders' Equity

Stockholders' Equity

In December 2024, the Company’s Board of Directors (the “Board") authorized a $50.0 million share repurchase program effective January 1, 2025 through December 31, 2026 to replace an expiring program of the same amount. For the three and six months ended June 30, 2025, the Company did not repurchase any shares, leaving the full amount of the $50.0 million authorization available as of June 30, 2025.

Revenue Recognition

Revenue Recognition

Revenue is measured based on the allocation of the transaction price in a contract to satisfied performance obligations. The transaction price does not include any amounts collected on behalf of third parties. The Company recognizes revenue when it satisfies a performance obligation by transferring control over a product or service to a customer. The following is a description of principal activities from which the Company generates its revenue, separated by reportable segments. Payments for our products and services are generally due within normal commercial terms. For a further discussion regarding the Company’s reportable segments, see Note 4 Segment Information.

Construction Products

The Construction Products segment primarily recognizes revenue when the customer has accepted the product and legal title of the product has passed to the customer.

Engineered Structures

Within the Engineered Structures segment, revenue is recognized for wind towers and certain utility structures over time as the products are manufactured using an input approach based on the costs incurred relative to the total estimated costs of production. We recognize revenue over time for these products as they are highly customized to the needs of an individual customer resulting in no alternative use to the Company if not purchased by the customer after the contract is executed. In addition, we have the right to bill the customer for our work performed to date plus at least a reasonable profit margin for work performed. As of June 30, 2025, we had a contract asset of $57.6 million related to these contracts, compared to $65.5 million as of December 31, 2024, which is included in receivables, net of allowance, within the Consolidated Balance Sheets. The decrease in the contract asset is attributed to timing of deliveries of finished structures to customers during the period. For all other products, revenue is recognized when the customer has accepted the product and legal title of the product has passed to the customer.

Transportation Products

The Transportation Products segment recognizes revenue when the customer has accepted the product and legal title of the product has passed to the customer.

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 June 30, 2025:

	Unsatisfied performance obligations as of  June 30, 2025
	Total Amount
	(in millions)
Engineered Structures:
Utility and related structures	$	450.0
Wind towers	$	598.6
Transportation Products:
Inland barges	$	277.0

In our Engineered Structures segment, 84% of the unsatisfied performance obligations for our utility and related structures are expected to be delivered during 2025, and substantially all of the remaining performance obligations are expected to be delivered in 2026. For our wind towers business, 30% are expected to be delivered during 2025, 24% are expected to be delivered during 2026, and the remainder are expected to be delivered through 2028.

For inland barges in our Transportation Products segment, 57% of the unsatisfied performance obligations are expected to be delivered during 2025, and the remainder are expected to be delivered in 2026.

Income Tax

Income Taxes

The liability method is used to account for income taxes. Deferred income taxes represent the tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. Valuation allowances reduce deferred tax assets to an amount that will more likely than not be realized.

The Company regularly evaluates the likelihood of realization of tax benefits derived from positions it has taken in various federal and state filings after consideration of all relevant facts, circumstances, and available information. For those tax positions that are deemed more likely than not to be sustained, the Company recognizes the benefit it believes is cumulatively greater than 50% likely to be realized. To the extent the Company were to prevail in matters for which accruals have been established or be required to pay amounts in excess of recorded reserves, the effective tax rate in a given financial statement period could be materially impacted.

Cash and Cash Equivalents

Financial Instruments

The Company considers all highly liquid debt instruments to be cash and cash equivalents if purchased with a maturity of three months or less.

Concentration of Credit Risk

Financial instruments that potentially subject the Company to a concentration of credit risk are primarily cash investments and receivables. The Company places its cash investments in bank deposits and highly-rated money market funds, and its investment policy limits the amount of credit exposure to any one commercial issuer. We seek to limit concentration of credit risk with respect to the Company's receivables with control procedures that monitor the credit worthiness of customers, together with the large number of customers in the Company's customer base and their dispersion across different industries and geographic areas. As receivables are generally unsecured, the Company maintains an allowance based upon the expected credit losses. Receivable balances determined to be uncollectible are charged against the allowance. To accelerate the conversion to cash, the Company may sell a portion of its trade receivables to third parties. The Company has no recourse to these receivables once they are sold but may have continuing involvement related to servicing and collection activities. The impact of these transactions in the Company's Consolidated Statements of Operations for the three and six months ended June 30, 2025 was not significant. The carrying values of cash, receivables, and accounts payable are considered to be representative of their respective fair values.

Recent Accounting Pronouncements

Recent Accounting Pronouncements

Recently adopted accounting pronouncements

Effective January 1, 2025, the Company adopted Accounting Standards Update No. 2023-09, “Income Taxes (Topic 740): Improvements to Income Tax Disclosures” (“ASU 2023-09”), which is intended to improve the transparency of income tax disclosures by requiring 1) consistent categories and greater disaggregation of information in the rate reconciliation and 2) income taxes paid disaggregated by jurisdiction. The standard also includes certain other amendments to improve the effectiveness of income tax disclosures. The additional disclosure requirements will be reflected in our Annual Report on Form 10-K for the year ending December 31, 2025. As ASU 2023-09 only modifies the Company's required income tax disclosures, the adoption of this guidance did not have a material impact on the Company's Consolidated Financial Statements.

Effective January 1, 2024, the Company adopted Accounting Standards Update No. 2023-07, “Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures” (“ASU 2023-07”), which is intended to improve reportable segment disclosure requirements, primarily through enhanced disclosures about significant segment expenses. The adoption of this guidance did not have a material effect on the Company's Consolidated Financial Statements.

Recently issued accounting pronouncements not adopted as of June 30, 2025

In November 2024, the FASB issued Accounting Standards Update No. 2024-03. "Income Statement-Reporting Comprehensive Income-Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses" ("ASU 2024-03"), which requires public business entities to disclose additional information about certain key expense categories within major income statement captions in the notes to consolidated financial statements. These enhanced disclosures are expected to help investors more effectively understand an entity's performance, assess its prospects for future cash flows, and compare an entity's performance over time and with that of other entities. ASU 2024-03 is effective for annual reporting periods beginning after December 15, 2026, and interim reporting periods beginning after December 15, 2027, and may be applied either prospectively or retrospectively. Early adoption is permitted. The Company is currently evaluating the impact of adopting ASU 2024-03 on its Consolidated Financial Statements.

Reclassification, Comparability Adjustment

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.
