Ever wonder who really owns the “steel in the sky” your phone connects to? Enter American Tower
$AMT — a textbook bottleneck business that Chuck Akre loves.

The brilliance: towers aren’t the story — incremental tenants are. Tenant 1 covers CapEx & OpEx modestly. Tenant 2 & 3? Pure margin upside with minimal spend — a “toll booth” effect.
Contracts are long-term and inflation-protected: ~3% escalators in the U.S., CPI-linked abroad. Even without new tenants, revenue compounds yearly.
5G densification is a tailwind — shorter-range signals require more equipment per tower, driving amendments and higher incremental rent.
Why I’m cautious:
• Debt load is heavy (~
$37B), with rates pressuring AFFO.
• 2026 guidance is conservative; growth may reset.
• Tenant risk: carriers are highly leveraged.
$AMT is a masterclass business, but even the best moat doesn’t guarantee the perfect entry. Watching from the sidelines for now.
