Bernstein and RBC Upgrade American Tower as 5G Densification and Data Centre Demand Restore Outlook
Positive for
Bernstein and RBC Capital have both upgraded American Tower, citing long-term 5G infrastructure demand and growing data centre co-location as the structural case for the cell tower REIT strengthens after a 24% decline driven by interest rate fears; Goldman Sachs separately highlighted AMT's data centre diversification as an underappreciated revenue growth driver.
Multiple Analyst Upgrades Follow a Deep Selloff
American Tower has attracted concurrent upgrades from Bernstein and RBC Capital, both citing the long-term structural demand for cell tower infrastructure as the basis for higher target prices. The upgrades follow a decline of approximately 24% in AMT shares that analysts attributed primarily to interest rate fears: as a real estate investment trust, American Tower's dividend yield competes with bonds, and its long-dated lease revenue gets valued at a higher discount rate when interest rates rise.
Bernstein's upgrade specifically references 5G network densification and data centre demand as the dual pillars of long-term revenue growth. RBC Capital's outperform rating reflects a similar view that the sell-off was disproportionate to the company's actual business fundamentals, which have continued to grow revenue through carrier lease escalators and international tower portfolio expansion.
The 5G Densification Case
American Tower derives most of its revenue from long-term leases to mobile carriers, Verizon, AT&T, T-Mobile, and their international equivalents, who pay to attach antennas and equipment to AMT's towers. The 5G upgrade cycle requires carriers to densify their networks significantly compared to 4G: the shorter range of mid-band and millimetre-wave 5G spectrum requires more transmission points, which translates directly to higher co-location demand on existing towers and new build demand where coverage gaps remain.
The 5G densification build-out in the United States has proceeded more slowly than initial forecasts, but the structural requirement does not go away. Carriers eventually need to densify or face coverage and capacity gaps as 5G device penetration grows and data consumption rises.
Data Centres as an Underappreciated Growth Driver
Goldman Sachs highlighted American Tower's data centre segment, which it characterised as underappreciated relative to the broader cell tower business. American Tower operates data centres primarily through its CoreSite segment, acquired in 2021 for approximately nine billion dollars. CoreSite provides carrier-neutral co-location and cloud connectivity facilities at interconnection hubs in major US markets.
As hyperscalers and enterprises expand their cloud and edge infrastructure, demand for interconnection at carrier-neutral data centres supports CoreSite's pricing and occupancy. The segment diversifies AMT's revenue beyond cell towers and gives it exposure to the same AI infrastructure buildout driving demand for semiconductor equipment and power utilities.

Frequently asked questions
What is a cell tower REIT and how does American Tower make money?
American Tower is a real estate investment trust that owns and leases space on communications towers to mobile carriers. Carriers pay long-term leases to attach antennas to AMT's towers, providing stable, escalating cash flows. The REIT model requires distributing most income to shareholders, making it sensitive to interest rates as an income investment.
Why did American Tower's stock fall 24% and what might reverse that?
Rising interest rates increase the discount rate applied to AMT's long-dated lease revenues and raise its financing costs, reducing the present value of the business. Multiple analyst upgrades suggest that with rates potentially stabilising or declining after the weak June jobs report, and with 5G and data centre demand intact, the sell-off may have overshot fundamental value.
