Crown Castle Inc. (NYSE: CCI) owns more than 40,000 cell towers in the United States and rents space on them to wireless carriers. It started in Houston in 1994 as Castle Tower, founded by Ted B. Miller Jr. and Edward C. Hutcheson Jr. with 133 towers, on the idea that several competing carriers could share one tower.
How the tower business works
Carriers sign long-term leases, typically with fixed escalators of about 3% a year, and pay more when they add or upgrade equipment. Because a tower costs about the same to run with one tenant or three, each extra lease adds margin. In FY2025 site rental produced $4.049B of Crown Castle's $4.264B revenue from continuing operations, and T-Mobile, AT&T, and Verizon accounted for 89% of consolidated revenue.
The fiber bet and its reversal
From 2015 to 2017 Crown Castle spent more than $10B on fiber networks, including the $7.1B Lightower deal, to build small cells for 5G. Returns trailed the tower business. Elliott Investment Management pressed for change in 2023, CEO Jay Brown retired, and founder Ted Miller ran an unsuccessful proxy fight in 2024. In 2025 the company agreed to sell Fiber Solutions to Zayo and Small Cells to EQT's Arium Networks for $8.5B, and the sale closed on May 1, 2026.
Crown Castle in 2026
CEO Christian Hillabrant, appointed in September 2025, now runs a tower-only REIT with about 1,250 employees. Sale proceeds paid down more than $7B of debt and funded a $1.0B buyback. Site rental revenue fell 4.1% to $967M in Q2 2026 as DISH terminations and Sprint cancellations ran through, but lower interest costs lifted AFFO per share to $1.13, and the company raised its FY2026 AFFO outlook to about $1.975B. The dividend is $1.0625 per quarter.
