CROWN CASTLE INC. company profile

Overview

Crown Castle Inc. is a U.S. communications-infrastructure company based in Houston, Texas. It owns, operates and leases approximately 40,000 cell towers and other structures across the United States, providing sites for wireless carriers to install equipment. The company describes its role as supporting the wireless connectivity used by people and businesses.[1]

Crown Castle previously operated fiber and small-cell networks, but sold those businesses in May 2026; its continuing business is focused on towers. Revenue from continuing operations was approximately $4.3 billion in 2025, primarily from site rentals.[5] [1]

Products & services

Crown Castle’s principal offering is access to shared wireless infrastructure. It leases or licenses space and capacity on more than 40,000 U.S. towers and other structures, including rooftops, where wireless carriers install antennas and related equipment. Tower-related services include site acquisition, architectural and engineering work, and zoning and permitting for equipment installations.[9]

Crown Castle has also provided small-cell and fiber infrastructure. It reported approximately 105,000 small-cell nodes generating revenue or under contract and roughly 90,000 route miles of fiber supporting small cells and fiber solutions. Small cells can be installed on infrastructure such as utility poles and streetlights to help wireless carriers add network coverage and capacity. In 2024, towers accounted for 67% of site-rental revenue and the Fiber segment for 33%; within Fiber, fiber solutions contributed 66% of site-rental revenue and small cells 34%.[9]

Crown Castle has agreed to sell its fiber solutions business to Zayo and its small-cell business to EQT. The sale was pending in its 2025 annual reporting, which presented those businesses as discontinued operations and Towers as the continuing reportable segment.[14] [9]

Geographic presence

Crown Castle’s communications infrastructure is concentrated in the United States, with more than 40,000 towers and other structures dispersed across the country. Its footprint also includes tower operations in Puerto Rico. Of its towers, 56% are in the 50 largest U.S. basic trading areas and 71% are in the 100 largest; the company reports a presence in each of the top 100 areas.[9]

Crown Castle is headquartered in Houston, Texas, and has offices elsewhere in the United States. Its fiber and small-cell networks are concentrated in major metropolitan markets, though those businesses were designated for sale in 2025. The company does not provide a country- or region-level revenue breakdown in the cited disclosures.[18] [9]

Business segments

Crown Castle’s historical reportable segments were Towers and Fiber. Towers leases space on communications towers to wireless carriers, primarily through long-term agreements. Fiber combined two activities: small cells, which provide wireless network capacity, and fiber solutions. Small cells were not a separate reportable segment.[9][10]

In its 2025 reporting, Crown Castle classified Fiber as discontinued operations in connection with a planned sale, leaving Towers as its sole reportable segment. Towers therefore accounted for 100% of continuing-operations revenue. For a view of the two businesses’ relative scale before the sale, Towers generated $4.264 billion of 2025 revenue and Fiber generated $2.173 billion: approximately 66% and 34%, respectively, of their combined revenue. That combined-revenue split is not a current reportable-segment breakdown.[6] [9]

Company history

Crown Castle and its predecessor were organized in 1995. The company expanded its U.S. communications-tower holdings through transactions involving businesses that became part of Verizon Wireless and AT&T in 1999–2000, followed by its merger with Global Signal in 2007.[24]

In 2012, Crown Castle added towers through a T-Mobile transaction and expanded into small-cell networks through its acquisition of NextG Networks. A further tower transaction with AT&T followed in 2013, and Crown Castle began operating as a real estate investment trust in 2014. It broadened its fiber and small-cell holdings with the acquisitions of Sunesys in 2015 and FiberNet and Lightower in 2017.[25] [24]
