Organization, Consolidation and Presentation of Financial Statements [Abstract] |
Basis of Presentation | Basis of Presentation The accompanying consolidated financial statements of AECOM (the Company) are unaudited and, in the opinion of management, include all adjustments, including all normal recurring items necessary for a fair statement of the Company’s financial position and results of operations for the periods presented. All intercompany balances and transactions are eliminated in consolidation. The consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in the Company’s Form 10-K for the fiscal year ended September 30, 2024 (the Annual Report). The accompanying unaudited consolidated financial statements and related notes have been prepared in accordance with generally accepted accounting principles (GAAP) in the United States (U.S.) for interim financial information and with the instructions to Form 10-Q and Rule 10-01 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. The consolidated financial statements included in this report have been prepared consistently with the accounting policies described in the Annual Report, except as noted, and should be read together with the Annual Report. The results of operations for the three months ended December 31, 2024 are not necessarily indicative of the results to be expected for the fiscal year ending September 30, 2025. As discussed in more detail in Note 3, the Company concluded that its self-perform at-risk construction businesses met the criteria for held for sale beginning in the first quarter of fiscal 2020 and met the criteria for discontinued operation classification. As a result, the self-perform at-risk construction businesses are presented in the consolidated statements of operations as discontinued operations for all periods presented. Current and non-current assets and liabilities of these businesses are presented in the consolidated balance sheets as assets and liabilities held for sale. The Company reports its annual results of operations based on 52- or 53-week periods ending on the Friday nearest September 30. The interim consolidated financial statements are presented for the periods ending on December 27, 2024, and December 29, 2023. For clarity of presentation, all periods are presented as if the periods ended on September 30 and December 31.
