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, isa provider of infrastructure-related products and solutions with leading positions in construction materials and engineeredstructures 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 onlybusiness included in the Transportation Products segment. We have concluded that the sale represented a strategic shiftwith a major effect on the Company's operations and financial results. Accordingly, the results of operations and cash flowsfor the three and six months ended June 30, 2026 have been classified as discontinued operations. Results of prior periodshave been recast to reflect these changes and present results on a comparable basis. Since there are no remainingoperations, the Transportation Products segment is no longer presented as a reportable segment. Unless indicatedotherwise, the information in the Notes to the Consolidated Financial Statements relates to the Company's continuingoperations. See further discussion in Note2. "Acquisitions and Divestitures." The accompanying Consolidated Financial Statements are unaudited and have been prepared from the books and recordsof Arcosa, Inc. and its consolidated subsidiaries. All normal and recurring adjustments necessary for a fair presentation of thefinancial position of the Company and the results of operations, comprehensive income/loss, and cash flows have beenmade in conformity with accounting principles generally accepted in the U.S. (“GAAP”). All significant intercompany accountsand transactions have been eliminated. Because of seasonal and other factors, the financial condition and results ofoperations for the three and six months ended June30, 2026 may not be indicative of Arcosa's expected business, financialcondition, and results of operations for the year ending December31, 2026. These interim financial statements and notes are condensed as permitted by the instructions to Form 10-Q and should beread in conjunction with the audited Consolidated Financial Statements of the Company included in its Annual Report onForm 10-K for the year ended December31, 2025.
