CROWN CASTLE INC.

Overview

Crown Castle Inc. is a U.S. communications-infrastructure real estate investment trust (REIT) that owns and leases wireless tower sites to mobile network operators and other tenants. Following the May 2026 sale of its Fiber Solutions and Small Cell businesses, its continuing operations are focused on cell towers and related site-development services. The company has a nationwide U.S. footprint, with a significant presence across the country’s largest wireless markets.[1]+2

The company describes its purpose as making connectivity possible and providing infrastructure that supports innovation. Founded in Houston in 1994, Crown Castle reported $4.264 billion in revenue for FY2025. Its latest cited employee count was approximately 4,000 as of January 31, 2026; that figure includes employees associated with the businesses subsequently sold, so it is not a post-sale headcount.[4]+3 [1]+6

Products & services

Crown Castle’s current infrastructure portfolio is centered on tower sites. Its towers include monopole, lattice, guyed, rooftop, and stealth installations; at year-end 2025, the company reported more than 40,000 towers and other structures, including rooftops. Customer agreements provide access to space or capacity on these structures, typically through leases, licenses, subleases, or service agreements.[1]+2

Related site-development services include structural analysis, zoning, permitting, and construction drawings. Crown Castle’s delivery process also covers engineering review, licensing, and pre-construction review.[10][11] In 2025, site-rental revenue represented 95% of total revenue.[12]

Crown Castle completed the sale of its small-cell and fiber-solutions businesses on May 1, 2026; these are no longer part of its current portfolio. Before the sale, the company reported approximately 105,000 small-cell nodes generating revenue or under contract and approximately 90,000 route miles of fiber.[13][1] [1]+6

Geographic presence

Crown Castle’s operating footprint is concentrated in the United States. At year-end 2025, before the sale of its small-cell and fiber-solutions businesses, it reported more than 40,000 towers, approximately 105,000 small-cell nodes and about 90,000 route miles of fiber across the country [1]. Its towers were broadly distributed across major U.S. markets: approximately 56% were in the 50 largest basic trading areas (BTAs), and 71% were in the 100 largest, with a significant presence in each of the top 100 BTAs [3]. The small-cell and fiber-solutions businesses were sold in a transaction that closed May 1, 2026; by Q2 2026, Crown Castle reported tower operations as its operating segment [14]+2.

The company’s principal executive offices are at 8020 Katy Freeway, Houston, Texas 77024-1908 [16]. Its filings do not provide revenue percentages by country or region, or an employee distribution by geography. [1]+5

Business segments

Crown Castle currently reports one operating segment: **Towers**. The company’s latest available reporting as of October 2, 2026 states that its reportable segment consists of towers operations; its former Fiber business is classified as discontinued operations following its sale on May 1, 2026.[17]+2

For FY2025, revenue categories—not separate reportable segments—were site rental, $4.049 billion (about 95% of $4.264 billion in net revenue), and services and other, $215 million (about 5%).[19][12]

Before the Fiber sale, Crown Castle reported Towers and Fiber as two segments. In FY2024, Towers included towers and other structures leased to wireless tenants, while Fiber included small-cell nodes and fiber routes supporting small cells and fiber solutions. Towers generated about 68% of those segments’ combined revenue and Fiber about 32%; this is a historical breakdown, not the current segment mix.[20][21] [17]+8

Company history

Founded in Houston in 1994 with 133 cell towers, Crown Castle was co-founded by Ted B. Miller Jr.; the company’s legal entity was organized in Delaware in 1995.[5]+2 It held its IPO in 1998 and expanded rapidly through U.S. tower acquisitions, including approximately 4,800 towers in 1999 and 2,700 in 2000, as well as an agreement to acquire about 700 Optus towers in Australia.[26]+2

In 2007, Crown Castle completed its merger with Global Signal, adding approximately 10,700 towers.[27][29] It later expanded its U.S. tower portfolio through transactions involving T-Mobile USA and AT&T towers in 2012–13, then sold its Australian subsidiary in 2015.[30]+2

In 2017, acquisitions of Wilcon and Lightower marked a major expansion into fiber; the Lightower deal brought its fiber rights to more than 60,000 route miles.[33][34] After several CEO transitions in 2023–25, Crown Castle agreed to sell its fiber-solutions and small-cells businesses in 2025; the sale closed in May 2026, with reported aggregate net cash proceeds of $8.4 billion.[35]+4 [25]+28
