## Overview

American Tower is a REIT that owns, operates and develops multitenant communications real estate—primarily wireless towers and other communications sites that host multiple tenants’ network equipment under long-term leases. The core business is leasing space on these sites to wireless service providers and other connectivity users, complemented by a U.S. portfolio of interconnected data center facilities that generate rental, power and interconnection-related revenue. The company also runs a smaller U.S. services operation that supports site leasing activity by handling site application, zoning/permitting, engineering analyses and construction/program management. Its economics are driven by adding incremental tenants and equipment (“colocations”) to existing sites and by selective new builds/acquisitions where demand supports returns.

## Customers

Customers are primarily wireless service providers that lease vertical real estate on towers to deploy and densify 4G/5G radio networks, with economics tied to coverage, capacity and speed-to-market. Additional tenants include radio and television broadcasters, wireless data providers, government agencies and municipalities that need reliable site access and elevation for communications equipment. In international markets, many tenants are local subsidiaries of global telecom groups, which can create credit and funding variability at the operating-company level. Data center customers lease space and power and purchase interconnection services, where network density, grid constraints and service reliability influence buying decisions. A smaller set of customers also purchase U.S. services (permitting, engineering and construction management) to accelerate deployments on American Tower sites.

- **Wireless service providers (mobile network operators)** (primary) — Lease tower space for macro coverage and 4G/5G upgrades; colocations and amendments drive incremental revenue.
- **Other communications tenants (broadcast, wireless data, enterprise)** (secondary) — Lease space on towers/structures for broadcast transmission and specialized wireless connectivity needs.
- **Public sector (government agencies and municipalities)** (secondary) — Lease site space for public safety and municipal communications where location and uptime matter.
- **Data center customers** (emerging) — Lease U.S. data center space and power and purchase interconnection solutions; value network density and reliability.

- Wireless carriers leasing tower space for 4G/5G coverage and capacity
- Broadcasters placing radio/TV equipment on tall structures
- Government agencies/municipalities needing resilient comms locations
- Wireless data providers and other connectivity tenants on towers
- Data center tenants buying colocation space, power and interconnection
- Tenants using U.S. permitting/engineering/construction services to deploy faster

## Geography

American Tower operates a large, diversified portfolio across the United States & Canada, Latin America, Europe, and Africa & APAC, with owned and operated towers in each region. Disclosed site counts highlight scale in the U.S. (owned and operated towers), substantial footprints in Brazil, Mexico and other Latin American markets, and large European portfolios in Germany, Spain and France. The company also operates U.S. data centers (30 facilities across 11 U.S. markets as of March 31, 2025), making U.S. power availability and grid constraints operationally important. Geographic diversification spreads carrier spending cycles and regulatory environments, but increases exposure to local permitting regimes, currency volatility and customer credit conditions in emerging markets. The company’s ability to add tenants and upgrade capacity varies by jurisdiction due to zoning/permitting and structural constraints.

- U.S. & Canada: large owned and operated tower base plus U.S. DAS sites
- Latin America: major tower footprints in Brazil and Mexico plus Andean markets
- Europe: significant presence in Germany and Spain; additional sites in France
- Africa & APAC: multi-country tower portfolios including Nigeria, Kenya, Uganda
- U.S. data centers: 30 facilities across 11 markets; power/grid constraints matter
- Local zoning/permitting differences affect speed and cost of new builds/augments

## Strategy

Strategy centers on increasing tenancy and equipment on existing communications sites, because incremental colocations typically generate high returns relative to new builds. The company targets demand from ongoing 5G deployments in the U.S. and from 4G/5G upgrades in international markets, while using modest augmentation capex to expand structural capacity where needed. It also pursues selective portfolio growth through capital expenditures, acquisitions and platform expansion initiatives, balancing return criteria against integration and permitting risks. In data centers, growth is tied to new lease commencements/expansions, contractual escalators and interconnection solutions, with competitive differentiation influenced by interconnection density and power availability. Operationally, U.S. services offerings support leasing by helping tenants and the company navigate site selection, permitting and construction execution.

- **Increase occupancy on existing communications sites** (medium-term) — Incremental tenants/equipment on existing towers typically deliver the highest incremental returns and leverage existing locations and permits.
- **Selective portfolio growth through capex, acquisitions and expansion** (medium-term) — Adds new sites and market presence where customer demand supports returns, while diversifying tenant and country exposure.
- **Expand data center leasing and interconnection solutions in the U.S.** (medium-term) — Data center revenue growth is driven by new commencements/expansions and interconnection density, but depends on power availability and execution.

- Drive colocations and lease amendments to raise tower occupancy
- Support U.S. 5G deployment activity and international 4G/5G upgrades
- Use tower augmentations to unlock additional structural capacity
- Selective acquisitions/platform expansions subject to ROI discipline
- Grow U.S. data centers via new leases, expansions and interconnection services
- Use in-house U.S. services to speed permitting and construction on sites

## Risks

The business depends on the financial health and capital spending of a concentrated set of communications service providers; carrier consolidation, network rationalization or funding constraints can increase churn and reduce new leasing activity. Competitive intensity is high across towers, alternative structures (rooftops, utility/water towers) and data centers, which can pressure pricing and acquisition economics. Operational risks include physical damage, access limitations and service interruptions at towers and data centers from natural disasters, power loss, fiber cuts, equipment failure or human error; data centers add heightened exposure to grid distribution constraints and uptime requirements. The company also faces cybersecurity risk across IT systems and data center operations, where breaches can cause outages, liability and reputational harm. Regulatory and public-perception risks (including claims about health effects of 5G) can slow deployments and complicate permitting, while expansion/acquisition initiatives carry integration, permitting and cost overrun risks.

- **Customer financial strength and funding constraints** [high] — Long-term leases rely on tenants’ ability to fund operations and network capex; downturns, FX volatility and tighter credit can reduce demand or trigger exits.
- **Tenant-specific network pullbacks (example: DISH/Echostar)** [medium] — Network decommissioning and reduced deployments can increase churn and reduce leasing demand; DISH was ~2% of total property revenue in 2025 per disclosure.
- **Data center operational interruptions and power availability constraints** [high] — Failures or grid constraints can cause outages, equipment damage and customer loss; risks include power loss, fiber cuts, cyber/physical breaches and disasters.
- **Cybersecurity incidents and loss of sensitive data** [high] — Attacks (ransomware, malware, social engineering, insider threats) can disrupt operations and create liability; customer security assurances heighten reputational impact.
- **Public perception and regulation regarding wireless/5G health effects** [medium] — Campaigns or findings alleging RF health risks can slow industry growth, harm relationships and complicate permitting and site access.
- **Expansion/acquisition integration and execution risk** [medium] — Returns depend on timely integration; risks include higher construction costs, supply chain disruptions, missing permits and operational complexity.

- Tenant credit/capex risk: carriers may cut spend or exit markets
- Elevated churn risk in U.S. & Canada tied to carrier lease cancellations
- Competition from other tower firms and alternative structures (rooftops, etc.)
- Data center uptime and power/grid constraints can cause service interruptions
- Cybersecurity incidents could disrupt operations and damage reputation
- Physical risks: storms, fire, vandalism, sabotage impacting towers/data centers
- Public perception/regulatory actions on 5G health concerns may slow deployments
- Acquisition/expansion integration risk and construction/supply chain cost inflation

## Accounting

Financial reporting relies on management estimates and judgments that affect the carrying values of towers, data centers and other long-lived assets, including periodic impairment assessments when indicators arise. Goodwill is tested at least annually at the reporting unit level using discounted cash flow models, where assumptions such as WACC and terminal growth can materially change impairment outcomes (e.g., a goodwill impairment was recorded in Spain in 2023 due to higher WACC). Revenue recognition requires judgment across leasing-related revenues and pass-through items (e.g., tenant reimbursements for ground rent, power and fuel) and includes straight-line revenue effects that can decouple reported revenue from cash receipts in a period. The company’s portfolio includes lease and sublease arrangements (including towers held under long-term finance leases), which can affect classification, depreciation/amortization patterns and cash flow presentation. Income taxes and uncertain positions across multiple jurisdictions, along with discontinued operations/held-for-sale assessments (when applicable), can also affect comparability across periods.

- **Impairment of long-lived assets (assets subject to depreciation/amortization)** — Can create non-cash charges and reduce asset carrying values and future depreciation.
- **Goodwill impairment testing (reporting unit level)** — Non-cash impairment charges can materially affect operating income and net income.
- **Revenue recognition and straight-line rent / pass-through items** — May inflate/deflate period revenue vs cash receipts; pass-through can raise revenue with limited margin.

- Long-lived asset impairment testing for towers and data centers
- Goodwill impairment uses DCF assumptions (WACC, terminal growth, tax rate)
- Straight-line revenue can shift timing vs cash rent collections
- Pass-through revenues/expenses (ground rent, power, fuel) affect reported revenue
- Lease accounting for finance leases and purchase options on operated towers
- Discontinued operations/held-for-sale judgments can affect period comparability
- Income tax estimates across jurisdictions impact effective tax rate
