Overview
Crown Castle is a U.S. tower REIT after completing the Fiber Business sale for $8.4B of net cash on May 1, 2026. Its continuing business owns or operates approximately 40,000 hard-to-replicate U.S. towers, with 45% of adjusted site-rental gross margin on owned land and 90% on land controlled for more than ten years. Tenant contracts generally start at five to 15 years with escalators; the remaining term averaged five years and represented about $22.1B of expected cash inflows excluding DISH. Q2 site-rental revenue fell 4% and gross margin 5% as DISH terminations and Sprint consolidation outweighed new leasing and escalators. T-Mobile, AT&T and Verizon supplied 93% of first-half site-rental revenue, creating substantial counterparty bargaining and churn risk.

Evidence
Nationwide portfolio concentrated in major U.S. markets; hard for new entrants to replicate at similar scale.
Physical Network Density moat: definition, examples, and stocks
Erosion risks
- Tenant consolidation reducing redundant leases
- New site alternatives (rooftops, utility structures) in select metros
- Substitute technologies (e.g., satellite) reducing macro demand at the margin
Leading indicators
- Net new tenant billings / churn
- Carrier network capex and 5G upgrade cycle
- Amendment and colocation activity per tower
Counterarguments
- American Tower and SBA have comparable nationwide footprints in many markets
- Carriers can still choose self-build or alternative structures for incremental coverage

Permits Rights Of Way
Strength
Durability
Confidence
Evidence
Long-duration control of tower sites (owned land, easements, and long-dated ground leases) supports durable site access.
Permits Rights Of Way moat: definition, examples, and stocks
Erosion risks
- Ground lease renewals resetting at higher rents
- Municipal zoning or permitting constraints on modifications
- Site loss from non-renewal of a minority of short-dated ground leases
Leading indicators
- Percent of tower gross margin on land controlled >10 and >20 years
- Ground lease renewal spreads and churn
- Number of sites with <10 years remaining on land agreements
Counterarguments
- In some geographies, competitors can still secure new sites or alternative structures
- Landlords may have bargaining power when leases roll
Long Term Contracts
Demand
Long Term Contracts
Strength
Durability
Confidence
Evidence
Long-term tenant contracts with escalators create recurring cash flows and reduce near-term churn sensitivity.
Long Term Contracts moat: definition, examples, and stocks
Erosion risks
- Carrier consolidation leading to non-renewals (e.g., network rationalization)
- Repricing pressure on renewals in competitive metros
- Technology shifts reducing incremental amendment demand
Leading indicators
- Weighted-average remaining term trend
- Non-renewals and early termination activity
- Contractual escalator realization vs negotiated offsets
Counterarguments
- Large carriers have concentrated bargaining power and can pressure rates on new leasing
- Some demand is cyclical with carrier capex timing
Evidence
The Company owns, operates and leases approximately 40,000 towers and other structures, such as rooftops
Shows scale of the U.S. tower footprint that underpins density advantages.
Approximately 56% and 71% of our towers are located in the 50 and 100 largest U.S. basic trading areas
Concentration in top markets improves network coverage relevance and co-location demand.
The contracts for the land under our towers have an average total remaining life of approximately 35 years
Long land-control duration reduces risk of losing sites and makes replication slower for competitors.
represented approximately 45% of our towers Adjusted Site Rental Gross Margin
Owned land, including fee interests and perpetual easements, generated 45% of tower adjusted site-rental gross margin; 90% had more than ten years of control.
Our tenant contracts have initial terms generally between five to 15 years, with contractual escalators
Supports durability of contracted tower cash flows.
