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, 2025 (“2025 Annual Report on Form 10-K”). Company Overview Arcosa, 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. Market Outlook •Within our Construction Products segment, market demand remains healthy overall when seasonal weather conditions have been normal, supported by 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. •Within our Engineered Structures segment, our backlog for utility and related structures as of June 30, 2026 was $648.1 million, up 49% year to date, and provides strong production visibility for the remainder of 2026. In utility structures, order and inquiry activity continues to be very healthy, as customers remain focused on grid hardening and reliability initiatives, along with increasing demand for electricity stemming from AI-driven projects. Due to increased demand, we have converted an idled wind tower facility to utility structures, which began delivering utility poles in the second quarter. Additionally, we plan to convert one of our existing wind tower facilities to utility structures in 2027. •For our wind towers business, market demand has historically been impacted by the level of federal tax credits available. The One Big Beautiful Bill Act ("OBBBA"), which was enacted on July 4, 2025, terminates the AMP tax credit for wind towers sold after 2027. Also, under the OBBBA, wind farm projects that began construction after July 4, 2026, and are not placed in service before the end of 2027, will not be eligible for the Production Tax Credit ("PTC"). Notwithstanding these developments, we remain confident that further investment in wind energy is needed to meet the load growth demands in the U.S. As of June 30, 2026, our backlog for wind towers was $537.4 million and we expect to recognize 28% during the remainder of 2026. 23 Table of Contents Executive Overview Recent Developments 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. On 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”). The consummation of the Merger is subject to the satisfaction or waiver of customary closing conditions, set forth in the Merger Agreement, among other things, including approval by the Company's stockholders and the receipt of required regulatory approvals. If the Merger is consummated, the Company's common stock will be delisted from the New York Stock Exchange and NYSE Texas and deregistered under the Securities Exchange Act of 1934, as amended (the "Exchange Act"). The transaction is expected to close in the first quarter of 2027. See Note 1. "Overview and Summary of Significant Accounting Policies" to the Consolidated Financial Statements for additional information about the Merger. 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, along with a receivable of $10 million related to escrow, after transaction closing costs. In April 2026, the Company used $83.0 million of the cash proceeds to prepay a portion of the outstanding 2025 Refinancing Term Loan. 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. Previously reported in the Transportation Products segment, the barge business is a leading manufacturer of inland barges, fiberglass barge covers, winches, and marine hardware located along the U.S. inland river systems. 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 MD&A relates to the Company's continuing operations. Financial Operations and Highlights •Revenues for the three and six months ended June 30, 2026 increased by 1.7% and 3.0% to $658.7 million and $1,230.4 million, respectively, from the same periods in 2025. •Operating profit for the three and six months ended June 30, 2026 increased by $2.3 million and $8.4 million, respectively, to $84.3 million and $131.4 million, respectively, compared to the same periods in 2025. •Selling, general, and administrative expenses increased by 27.3% and 17.0% for the three and six months ended June 30, 2026, respectively, compared to the same periods in the prior year, driven by higher acquisition and divestiture-related expenses, including those related to the proposed Merger, and compensation-related costs. As a percentage of revenues, selling, general, and administrative expenses were 13.5% and 13.4% for the three and six months ended June 30, 2026, respectively, compared to 10.8% and 11.8% for the same periods in 2025, respectively. •Interest expense for the three and six months ended June 30, 2026 totaled $23.1 million and $47.1 million, respectively, a decrease of $5.4 million and $9.7 million, respectively, from the same period in 2025. •The effective tax rate from continuing operations for the three and six months ended June 30, 2026 was 18.3% and 14.6%, respectively, compared to 11.4% and 13.0%, respectively, for the same periods in 2025. •Net income from continuing operations for the three and six months ended June 30, 2026 was $50.9 million and $74.2 million, respectively, compared to $50.5 million and $62.1 million, respectively, for the same periods in 2025. Our Engineered Structures segment operates 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. 24 Table of Contents Unsatisfied Performance Obligations (Backlog) As of June 30, 2026, December 31, 2025, and June 30, 2025, our unsatisfied performance obligations, or backlog, were as follows: June 30, 2026 December 31, 2025 June 30, 2025 (in millions) Engineered Structures: Utility and related structures $ 648.1 $ 434.9 $ 450.0 Wind towers $ 537.4 $ 627.8 $ 598.6 In our Engineered Structures segment, 71% of the unsatisfied performance obligations for our utility and related structures 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 further discussion of revenues, costs, and the operating results of individual segments, see Segment Discussion below. 26 Table of Contents Income Taxes The provision for income taxes results in effective tax rates that differ from the statutory rates. The Company's effective tax rate for continuing operations for the three and six months ended June 30, 2026 was 18.3% and 14.6%, respectively, compared to 11.4% and 13.0%, respectively, for the same periods in 2025. The change in the tax rate for the three and six months ended June 30, 2026 was primarily due to a reduction in AMP tax credits due to lower wind tower volumes and an increase in foreign taxes, partially offset by lower state taxes. For the three months ended June 30, 2026, the tax rate was also impacted by a lower compensation-related benefit in the current period due to a change in the timing of restricted stock vestings. Our effective tax rate differs from the federal tax rate of 21.0% due to AMP tax credits, state income taxes, statutory depletion deductions, compensation-related items, and other foreign adjustments. See Note 9. "Income Taxes" to the Consolidated Financial Statements for further discussion of income taxes.

Three Months Ended June 30, 2026 versus Three Months Ended June 30, 2025 •Segment revenues increased 0.7%. For construction materials, revenues decreased 1.3% primarily due to lower organic aggregates and asphalt volumes which were impacted by wet weather during the period. This decline was partially offset by higher pricing and the contribution from recent acquisitions. Revenues from construction site support increased 17.6% primarily due to higher volumes from our trench shoring business. •Cost of revenues increased 2.3% primarily due to higher trench shoring volumes, the contribution from recent acquisitions, and increased costs in our specialty and asphalt businesses, partially offset by reduced costs in our organic aggregates business. As a percentage of revenues, cost of revenues were 77.4% in the current period, compared to 76.2% in the prior period. •Selling, general, and administrative expenses increased 9.2% primarily due to higher compensation-related expenses and an increase in bad debt expense driven by a favorable adjustment recognized in the prior period related to increased collections on previously reserved receivables. Selling, general, and administrative expenses as a percentage of revenues were 9.3% in the current period, compared to 8.5% in the prior period. 27 Table of Contents •Operating profit decreased 6.0% primarily due to lower asphalt volumes and less favorable project mix in our asphalt paving business and higher depreciation, depletion, and amortization expense, partially offset by improved profitability in aggregates and trench shoring. •Depreciation, depletion, and amortization expense increased 8.1%, outpacing revenue growth, primarily due to capital investments and recent acquisitions, including the fair market value write-up of long-lived assets. Six Months Ended June 30, 2026 versus Six Months Ended June 30, 2025 •Segment revenues increased 2.6%.

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 continuing operations from operating, investing, and financing activities for the six months ended June 30, 2026 and 2025: Six Months Ended June 30, 2026 2025 (in millions) Total cash provided (required) by: Operating activities $ 33.4 $ 16.9 Investing activities (147.9) (31.6) Financing activities (123.8) (24.7) Net decrease in cash and cash equivalents from continuing operations $ (238.3) $ (39.4) Operating Activities from Continuing Operations.

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. 30 Table of Contents 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 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 had no 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). On June 17, 2025, we entered into Amendment No. 2 to the Credit Agreement, which established 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 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. In April 2026, the Company used $83 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. 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. 31 Table of Contents 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 2026, the Company declared a quarterly cash dividend of $0.05 per share that was paid on July 31, 2026. 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. See Note 1.
