Risks & Considerations

High Capex Requirements

Telecom companies must reinvest approximately 18% of revenue into network upgrades (5G, fiber) to remain competitive, which can limit free cash flow growth.

Subscriber Saturation

With wireless penetration at nearly 100% in the US, companies must rely on aggressive pricing wars or service bundling to steal market share from competitors.

Interest Rate Exposure

The sector, especially Tower REITs like AMT, carries significant debt loads to fund infrastructure; rising rates can increase interest expense and depress stock valuations.

Technological Obsolescence

The shift toward space-based cellular broadband (ASTS) could potentially disrupt traditional terrestrial tower models if satellite connectivity achieves global scale.
