Basis of Presentation [Abstract] |
Basis of Presentation | Basis of Presentation The consolidated financial statements include the accounts of Crown Castle Inc. and its predecessor, as applicable (together, "CCI"), and their subsidiaries, collectively referred to herein as the "Company." All significant intercompany balances and transactions have been eliminated in consolidation. As used herein, the term "including," and any variation thereof, means "including without limitation." The use of the word "or" herein is not exclusive. Unless the context suggests otherwise, references to "U.S." are to the United States of America and Puerto Rico, collectively. The Company owns, operates and leases shared communications infrastructure that is geographically dispersed throughout the U.S., including (1) towers and other structures, such as rooftops (collectively, "towers"), and (2) fiber primarily supporting small cell networks ("small cells") and fiber solutions. The Company's towers, small cells and fiber assets are collectively referred to herein as "communications infrastructure," and the Company's customers on its communications infrastructure are referred to herein as "tenants." The Company's core business is providing access, including space or capacity, to its shared communications infrastructure via long-term contracts in various forms, including lease, license, sublease and service agreements (collectively, "tenant contracts"). The Company's operating segments consist of (1) Towers and (2) Fiber. See note 14. On March 13, 2025, the Company signed a definitive agreement (“Strategic Fiber Agreement”) to sell its Fiber segment, together with certain supporting assets and personnel ("Fiber Business"), with Zayo Group Holdings Inc. ("Zayo") acquiring the fiber solutions business and EQT Active Core Infrastructure fund ("EQT") acquiring the small cell business ("Strategic Fiber Transaction"). The Fiber Business did not meet the criteria for assets held for sale as of December 31, 2024, and therefore remains presented as a component of continuing operations. As a result, this document, unless otherwise noted, does not contemplate the planned sale of the Fiber Business. In subsequent periods, the Fiber Business will be presented as a discontinued operation, and its net assets will be classified as held for sale and comparable prior periods will be recast to reflect this change. See note 17. Approximately 54% of the Company's towers are leased or subleased or operated and managed under master leases, subleases, and other agreements with AT&T and T-Mobile (including those which T-Mobile assumed in its merger with Sprint). The Company has the option to purchase these towers at the end of their respective lease terms. The Company has no obligation to exercise such purchase options. See notes 4 and 13. As part of the Company's effort to provide comprehensive communications infrastructure solutions, as an ancillary business, the Company also offers certain services primarily relating to its Towers segment. For the periods presented, such services predominately consisted of (1) site development services relating to existing or new tenant equipment installations, including: site acquisition, architectural and engineering, or zoning and permitting (collectively, "site development services") and (2) tenant equipment installation and subsequent augmentations (collectively, "installation services"). See note 16 to the Company's consolidated financial statements for a discussion of (1) the Company's July 2023 restructuring plan ("2023 Restructuring Plan"), which included discontinuing installation services as a Towers product offering and (2) the Company's June 2024 restructuring plan ("2024 Restructuring Plan," and together with the 2023 Restructuring Plan, "Restructuring Plans"). The Company operates as a REIT for U.S. federal income tax purposes. In addition, the Company has certain taxable REIT subsidiaries ("TRSs"). See note 9. The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities as of the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.
