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 positions in construction materials and engineered structures markets in North America. Arcosa is a Delaware corporation and was incorporated in 2018.

On April 1, 2026, the Company completed the previously announced sale of its barge business, which was the only business included in the Transportation Products segment. We have concluded that the sale represented a strategic shift with a major effect on the Company's operations and financial results. Accordingly, the results of operations and cash flows for the three and six months ended June 30, 2026 have been classified as discontinued operations. Results of prior periods have been recast to reflect these changes and present results on a comparable basis. Since there are no remaining operations, the Transportation Products segment is no longer presented as a reportable segment. Unless indicated otherwise, the information in the Notes to the Consolidated Financial Statements relates to the Company's continuing operations. See further discussion in Note 2. "Acquisitions and Divestitures."

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, 2026 may not be indicative of Arcosa's expected business, financial condition, and results of operations for the year ending December 31, 2026.

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, 2025.

Merger Agreement

On June 21, 2026, the Company entered into an Agreement and Plan of Merger (the "Merger Agreement") by and among the Company, CRH Americas, Inc., a Delaware corporation ("CRH"), and Neon Merger Sub, Inc., a Delaware Corporation and a wholly owned subsidiary of CRH ("Merger Sub"). Pursuant to the Merger Agreement, and subject to the terms and conditions set forth therein, Merger Sub will merge with and into the Company (the “Merger”), with the Company surviving the Merger as a wholly owned subsidiary of CRH. Per the terms and subject to the conditions set forth in the Merger Agreement, at the effective time of the Merger ("Effective Time"), each share of Company common stock, par value $0.01 per share, issued and outstanding immediately prior to the Effective Time will be automatically converted into the right to receive $150.00 in cash, without interest and subject to applicable withholding taxes (the “Merger Consideration”).

Pursuant to the Merger Agreement, at the Effective Time, outstanding restricted stock and restricted stock unit awards granted prior to the date of the Merger Agreement will become vested and be settled for cash, without interest, in an amount equal to the Merger Consideration, payable per share, plus any accrued and unpaid dividend equivalents, less applicable withholding taxes. The number of shares of Company common stock subject to outstanding performance-based awards will be settled based on the greater of target performance or actual performance achieved prior to the Effective Time, as determined by the Company's Board of Directors (the "Board") (or an appropriate committee of the Board).

The consummation of the Merger is subject to the satisfaction or waiver of customary closing conditions, set forth in the Merger Agreement, including, among other things: (i) the approval of the holders of a majority of the voting power represented by the outstanding shares of Company common stock entitled to vote thereon (the “Company Stockholder Approval”); (ii) the absence of any law, injunction or order (whether temporary, preliminary or permanent) by any governmental entity that has the effect of restraining, enjoining or otherwise prohibiting the Merger; (iii) the expiration or termination of the applicable waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, and; the receipt or waiver of specified regulatory approvals in the required jurisdictions outside the United States; (iv) other customary conditions specified in the Merger Agreement, including (a) each party’s representations and warranties being true and correct, subject to certain customary qualifications, (b) each party’s compliance with or performance of, in all material respects, its obligations under the Merger Agreement and (c) the absence of a material adverse effect with respect to the Company. The transaction is not subject to financing conditions. Subject to such conditions, the Company expects to consummate the Merger in the first quarter of 2027.

The Merger Agreement contains certain termination rights for both the Company and CRH, including, among others, the right of (i) either party to terminate the Merger Agreement if the Merger is not consummated by June 21, 2027 (subject to up to a six month extension if certain closing conditions have not been satisfied or waived), (ii) the Company, prior to receiving the Company Stockholder Approval, to terminate the Merger Agreement in order to enter into a definitive acquisition agreement providing for a Superior Proposal (as defined in the Merger Agreement) and (iii) CRH, prior to receiving the Company Stockholder Approval, to terminate the Merger Agreement if a Change in Recommendation has occurred (as defined in the Merger Agreement). The Merger Agreement provides for the payment of termination fees under specified circumstances. Under certain circumstances, CRH may be required to pay the Company a termination fee of approximately $372.0 million, and the Company may be required to pay CRH a termination fee of approximately $260.4 million. The Company has incurred and will incur certain costs relating to the proposed Merger, such as financial advisory, legal, and other professional service fees.

Stockholders' Equity

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. During the three months ended June 30, 2026, the Company did not repurchase any shares. During the six months ended June 30, 2026, the Company repurchased 159,595 shares at a cost of $17.5 million. As of June 30, 2026, the Company has approximately $32.5 million available for share repurchases under the current program.

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, 2026, we had a contract asset of $93.7 million related to these contracts, compared to $65.1 million as of December 31, 2025, which is included in receivables, net of allowance, within the Consolidated Balance Sheets. The increase in the contract asset is attributed to higher volumes and the timing of deliveries of finished structures to customers during the period. For all other products, revenue is recognized when the customer has accepted the product and legal title of the product has passed to the customer.

Revenues

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

Unsatisfied Performance Obligations

The following table includes estimated revenue expected to be recognized in future periods related to performance obligations that are unsatisfied or partially satisfied as of June 30, 2026:

For our utility and related structures business,71% of the unsatisfied performance obligations are expected to be recognized during 2026,20% are expected to be recognized in 2027, with the remainder expected to be recognized through 2029. For our wind towers business,28% of the unsatisfied performance obligations are expected to be recognized during 2026,66% are expected to be recognized in 2027, with the remainder expected to be recognized in 2028.

Advance Billings

Advance billings represent cash collected from customers prior to the satisfaction of the related performance obligations and are separately presented on the Consolidated Balance Sheets. For the three and six months ended June 30, 2026, the Company recognized as revenue approximately $8.8 million and $16.1 million, respectively, of the advance billings balance outstanding at the beginning of the year. For the three and six months ended June 30, 2025, the Company recognized as revenue approximately $23.1 million and $69.8 million, respectively, of the advance billings balance outstanding at the beginning of the year.

Income Taxes

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

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

Financial Instruments

The Company considers all highly liquid debt instruments to be cash and cash equivalents if purchased with a maturity of three months or less. Financial instruments that potentially subject the Company to a concentration of credit risk are primarily cash investments and receivables. The Company places its cash investments in bank deposits and highly-rated money market funds, and its investment policy limits the amount of credit exposure to any one commercial issuer. We seek to limit concentration of credit risk with respect to the Company's receivables with control procedures that monitor the credit worthiness of customers, together with the large number of customers in the Company's customer base and their dispersion across different industries and geographic areas. As receivables are generally unsecured, the Company maintains an allowance based upon the expected credit losses. Receivable balances determined to be uncollectible are charged against the allowance. To accelerate the conversion to cash, the Company may sell a portion of its trade receivables to third parties. The Company has no recourse to these receivables once they are sold but may have continuing involvement related to servicing and collection activities. The impact of these transactions in the Company's Consolidated Statements of Operations for the three and six months ended June 30, 2026 and 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 issued accounting pronouncements not adopted as of June 30, 2026

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

2026 Acquisitions

During the six months ended June 30, 2026, the Company completed three acquisitions within our Construction Products segment, including two recycled aggregates businesses based in New Jersey and Colorado, respectively, and one natural aggregates business based in Florida, for a total purchase price of $84.9 million. The acquisitions were recorded as business combinations and preliminary valuation estimates resulted in the recognition of, among other assets and liabilities, $49.3 million of mineral reserves, $19.2 million of goodwill, and $14.0 million of intangible assets in our Construction Products segment.

2025 Acquisitions

There wereno acquisitions completed during the three and six months ended June 30, 2025.

2026 Divestitures - Discontinued Operations

On April 1, 2026, the Company completed the sale of its barge business to an affiliate of Wynnchurch Capital, L.P., for $450 million. Net cash proceeds received at closing were approximately $429.9 million after transaction closing costs, and $10 million in escrow recorded as a current receivable. The sale resulted in a pre-tax gain of $359.7 million, which is presented within income from discontinued operations, net of income taxes on the Consolidated Statements of Operations. The barge business, historically presented within the Transportation Products segment, is a leading manufacturer of inland barges, fiberglass barge covers, winches, and marine hardware with operations located along the U.S. inland river systems. The Company is performing routine services under a transition services agreement and will have no other continuing involvement with the divested business. We have concluded that the sale represented a strategic shift with a major effect on the Company's operations and financial results. Accordingly, results of operations and cash flows for the three and six months ended June 30, 2026 have been classified as discontinued operations. Results of prior periods have been recast to reflect these changes and present results on a comparable basis. In April 2026, the Company used $83.0 million of the cash proceeds to prepay a portion of the outstanding 2025 Refinancing Term Loan. See Note 7. "Debt" for additional information.

The following table summarizes the major line items for the barge business that are included in income from discontinued operations, net of income taxes, on the Consolidated Statements of Operations:

The following table summarizes the assets and liabilities of the barge business which have been classified as discontinued operations on the Consolidated Balance Sheets:

2025 Divestitures

There wereno divestitures completed during the three and six months ended June 30, 2025.

Note 3. Fair Value Accounting

Assets and liabilities measured at fair value on a recurring basis are summarized below:

(1)Included in other assets on the Consolidated Balance Sheets.

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.

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. Since there are no remaining operations, the Transportation Products segment is no longer presented as a reportable segment. See further discussion in Note 2. "Acquisitions and Divestitures." The Company reports operating results intwo 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.

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

Note 5. Property, Plant, and Equipment

The following table summarizes the components of property, plant, and equipment as of June 30, 2026 and December 31, 2025:

During the three and six months ended June 30, 2026, the Company recognized gains on the disposition of property, plant, and equipment of $19.9 million and $21.9 million, respectively. During the three and six months ended June 30, 2025, the Company recognized gains on the disposition of property, plant, and equipment of $4.5 million and $8.3 million, respectively. These gains primarily related to the sale of land and equipment. The gains on disposition of property, plant, and equipment are included in other operating income on the Consolidated Statements of Operations.

Note 6. Goodwill and Other Intangible Assets

Goodwill

Goodwill by segment is as follows:

The increase in Construction Products goodwill during the six months ended June 30, 2026 is due to the acquisitions completed during the period. See Note 2. "Acquisitions and Divestitures" for additional information.

Intangible Assets

Intangibles, net consisted of the following:

Note 7. Debt

The following table summarizes the components of debt as of June 30, 2026 and December 31, 2025:

Revolving Credit Facility

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

On August 15, 2024, we entered into Amendment No. 1 to the Credit Agreement ("Amendment No. 1 to the Credit Agreement") to, among other things, (i) increase our revolving credit facility from $600.0 million to $700.0 million, (ii) collateralize the amended revolving credit facility with substantially all of our and our subsidiary guarantors' personal property (with certain exceptions), (iii) make the applicable margin for revolving borrowings, letters of credit and the commitment fee rate be based on our consolidated net leverage ratio (permitting up to $150.0 million of unrestricted cash to be netted from the calculation thereof), (iv) modify the margin for Secured Overnight Financing Rate ("SOFR")-based revolving borrowings and letters of credit to range from 1.25% to 2.50% per annum, (v) modify the margin for base rate revolving borrowings to range from 0.25% to 1.50%, (vi) modify the commitment fee that accrues on the unused portion of the revolving credit facility to range from 0.20% to 0.45%, and (vii) modify the maximum permitted leverage ratio to include a net debt concept (permitting up to $150.0 million of unrestricted cash to be netted from the calculation thereof), and to provide that such ratio shall be no greater than 4.00 to 1.00 during the first quarter of 2026, and 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 became effective on October 1, 2024. The amended revolving credit facility's maturity date of August 23, 2028 remains unchanged.

As of June 30, 2026, we hadno outstanding loans borrowed under our revolving credit facility.

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, 2026, the margin for borrowing based on SOFR was set at 1.75% and the commitment fee rate was set at 0.30%.

The revolving credit facility portion of the Credit Agreement requires the maintenance of certain ratios related to leverage and interest coverage. As of June 30, 2026, 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."

As of June 30, 2026, total unamortized debt issuance costs related to the prior and amended revolving credit facilities were $2.2 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, of which $100.0 million was used to pay down the Company's revolving credit facility. The 2024 Term Loan required, among other things, (i) mandatory prepayments from excess cash flow on an annual basis, commencing with the fiscal year ending December 31, 2025, (ii) mandatory prepayments with proceeds of certain asset sales and debt issuances, and (iii) quarterly principal amortization payments in an amount equal to 0.25% of the 2024 Term Loan. The 2024 Term Loan had a maturity date of October 1, 2031. The interest rate for the 2024 Term Loan was based on SOFR plus 2.25% per year. The 2024 Term Loan was guaranteed by the same subsidiaries of the Company that guarantee our revolving credit facility, and the 2024 Term Loan was secured on a pari passu basis with our revolving credit facility.

On June 17, 2025, we entered into Amendment No. 2 to the Credit Agreement to establish a new class of term loans (the "2025 Refinancing Term Loan") in an aggregate principal amount of $698.3 million. We used the 2025 Refinancing Term Loan's net proceeds, together with cash on hand, to satisfy the outstanding balance under the 2024 Term Loan. The interest rate for the 2025 Refinancing Term Loan is based on SOFR plus 2.00% per year, or an alternate base rate, plus 1.00% per year, a 0.25% per annum reduction from the 2024 Term Loan. The 2025 Refinancing Term Loan is prepayable at any time without premium or penalty (other than customary SOFR-related breakage costs). All other terms of the 2025 Refinancing Term Loan are the same as the 2024 Term Loan that was prepaid with the proceeds of the 2025 Refinancing Term Loan. In April 2026, the Company used $83.0 million of cash proceeds from the sale of the barge business to prepay a portion of the outstanding 2025 Refinancing Term Loan. See Note 2. "Acquisitions and Divestitures" for additional information.

In connection with the issuance of the 2025 Refinancing Term Loan, the Company incurred $0.8 million of debt issuance costs.

Senior Notes

On August 26, 2024, the Company issued $600.0 million aggregate principal amount of 6.875% senior unsecured notes (the "2024 Notes") that mature in August 2032. Interest on the 2024 Notes is payable semiannually in February and August. In April 2021, the Company issued $400.0 million aggregate principal amount of 4.375% senior unsecured notes (the "2021 Notes", and together with the 2024 Notes, the "Senior Notes") that mature in April 2029. Interest on the 2021 Notes is payable semiannually in April and October. The Senior Notes are senior unsecured obligations of the Company and are guaranteed on a senior unsecured basis by each of the Company’s domestic subsidiaries that is a guarantor under our Credit Agreement. The terms of each indenture governing the Senior Notes, among other things, limit the ability of the Company and each of its subsidiaries to create liens on assets, enter into sale and leaseback transactions, and consolidate, merge or transfer all or substantially all of its assets and the assets of its subsidiaries. The terms of each indenture also limit the ability of the Company’s non-guarantor subsidiaries to incur certain types of debt.

The Company has the option to redeem all or a portion of the Senior Notes at redemption prices set forth in the applicable indenture, plus accrued and unpaid interest to the redemption date. If a Change of Control Triggering Event (as defined in each applicable indenture) occurs, the Company must offer to repurchase the Senior Notes at a price equal to 101% of the principal amount of the Senior Notes, plus accrued and unpaid interest to the date of repurchase.

The estimated fair values of the 2024 Notes and 2021 Notes as of June 30, 2026 were $626.7 million and $393.6 million, respectively, based on quoted market prices in a market with little activity (Level 2 input).

The remaining principal payments under existing debt agreements as of June 30, 2026 are as follows:

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.

Future minimum lease payments for operating and finance lease obligations as of June 30, 2026 consisted of the following:

The following table summarizes our operating and finance leases and their classification within the Consolidated Balance Sheet:

Note 9. 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 2025 with various significant tax jurisdictions.

Our effective tax rates from continuing operations of 18.3% and 14.6% for the three and six months ended June 30, 2026, 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 from continuing operations of 11.4% and 13.0% for the three and six months ended June 30, 2025, respectively, differed from the U.S. federal statutory rate of 21.0% due to AMP tax credits, state income taxes, statutory depletion deductions, compensation-related items, and other foreign adjustments.

Note 10. Employee Retirement Plans

Total employee retirement plan expense, which includes related administrative expenses, is as follows:

The Company contributes to various multiemployer defined benefit pension plans under the terms of collective-bargaining agreements that cover certain union-represented employees at one of the facilities in our Engineered Structures segment and four of the facilities in our Construction Products segment. The Company contributed $0.8 million and $1.3 million to the multiemployer plans for the three and six months ended June 30, 2026 and 2025. Total contributions to these plans for 2026 are expected to be approximately $2.7 million.

Note 11. Accumulated Other Comprehensive Loss

Changes in accumulated other comprehensive loss for the six months ended June 30, 2026 and 2025 are as follows:

Note 12. Stock-Based Compensation

Stock-based compensation totaled approximately $6.0 million and $12.3 million for the three and six months ended June 30, 2026, respectively. Stock-based compensation totaled approximately $6.4 million and $12.8 million for the three and six months ended June 30, 2025, respectively.

Note 13. Earnings Per Common Share

Basic earnings per common share is computed by dividing net income remaining after allocation to participating unvested restricted shares by the weighted average number of basic common shares outstanding for the period. Except when the effect would be antidilutive, the calculation of diluted earnings per common share includes the weighted average net impact of nonparticipating unvested restricted shares. Total weighted average restricted shares were 0.7 million and 0.8 million for the three and six months ended June 30, 2026, respectively. Total weighted average restricted shares were 1.1 million for the three and six months ended June 30, 2025.

The computation of basic and diluted earnings per share follows:

Note 14. 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, 2026, we currently do not believe that a loss is probable, therefore no accrual has been included in the accompanying Consolidated Financial Statements.

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, 2026, the Company was contingently liable for $223.7 million in surety bonds, which guarantee the Company's own performance and are required by certain states and municipalities and their related agencies. The Company has indemnified the underwriting insurance companies against any exposure under the surety bonds. The Company is not aware of any circumstances that would result in material claims against these bonds.
