Combined average of Moat (AI Resilience), Growth, and Valuation scores.
Moat Score
American Tower's moat is physical-site scarcity plus switching costs: a global portfolio of communications sites where zoning, land control, and multi-tenant colocation make like-for-like replacement slow and expensive, wrapped in long-term carrier leases. CoreSite adds an interconnection layer still open for a deeper restamp.
AMT runs a Scarce Digital Real-Estate Toll that compounds through site control, lease duration, and colocation density:
- Site Scarcity and Zoning Friction: New macro sites face zoning, permitting, and community opposition that incumbents already cleared years ago. That scarcity is the primary barrier: carriers need coverage footprints, and relocating antennas is operationally disruptive. AMT's scale across U.S./Canada, LatAm, Africa & APAC, and Europe turns one-off local entitlements into a portfolio that competitors cannot assemble quickly.
- Long Leases and Switching Costs: Tenant relationships sit inside multi-year master lease agreements with contractual escalators. Moving equipment to another tower is costly in truck rolls, RF redesign, and network downtime — so churn is typically low outside discrete events (DISH being the current one). Q2 organic tenant billings were soft on a headline basis (~2%) but ~4% ex-DISH, with U.S./Canada ~5% ex-DISH — the lease machine under the churn print.
- Multi-Tenant Density Economics: Incremental colocations on an existing tower are high-incremental-margin. More tenants per site improve returns without a proportional land or steel cost — a mild supply-side network effect that favors the densest portfolios. Carrier densification (5G/capacity) and neutral-host demand reinforce that dynamic even when net organic billings are temporarily depressed by a single-tenant churn event.
- CoreSite Option (Open Question): CoreSite/data center property revenue is guiding ~15% growth and was called out as a raise driver in the Jul 28 outlook. Interconnection and cloud on-ramps can deepen switching costs beyond towers, but this first pass does not deep-dive utilization, book-to-bill, or AI/inference demand quality — flagged for a later restamp alongside international FX translation.
Moat Verdict
AMT's moat is AI-resilient physical scarcity: zoning-constrained sites, lease embedding, and colocation density. Software does not relocate steel. CoreSite is additive but not yet credited as a fully underwritten second fortress on this thin first pass.
65.0 resilient · 65.0 vulnerable · 80/20 = 65.0 · = 65
Open a moat to read its note.
Carriers do not build habitual UI workflows on AMT software. The stickiness is physical lease and RF redesign cost, scored under transaction embedding and system of record — not a learned interface.
Master lease agreements, escalators, and colocation workflows are industry-standard, but AMT's scale playbooks for zoning, build-to-suit, and multi-tenant stacking are operational know-how that smaller landlords copy slowly. AI does not erase the need for local entitlement and landlord execution.
Tower leasing does not depend on exclusive access to a public dataset. Coverage maps and FCC filings are widely available; the moat is owned sites and leases, not gated public data.
Site acquisition and zoning talent matters at the margin but is not scarce enough to be a primary moat versus portfolio scale and entitlements already won.
Towers plus CoreSite interconnection is a real bundle for carriers and cloud customers who want adjacent digital infrastructure — early and still an open depth question on this thin pass, but directionally intact rather than na.
Decades of lease terms, site performance, amendment history and entitlement outcomes improve pricing, churn prediction and capital allocation. Crown Castle and SBA hold the same kind of history on their own portfolios, and no figure shows AMT's yields a better result, so it rates intact.
Zoning, permitting and land-use rules make new macro sites slow to originate, so sites that already cleared local opposition are scarce. Every incumbent tower owner holds the same kind of entitled sites, so it is a barrier to new builders, not to peers, and rates intact.
Multi-tenant density improves site economics and can attract further colocations (supply-side density effect). It is real but weaker than classic two-sided software networks — scored intact, not strong.
Carrier equipment on an AMT site is wired into live network topology, and moving it costs capital, RF redesign and service risk; multi-year master lease agreements with escalators add to it. MLAs and escalators are industry standard, and DISH shows tenants do leave, so with no churn or renewal figure on file it rates intact.
Not a system of record: the owned site grid is a physical footprint, not the authoritative record a customer's workflow runs on. The switching cost it creates is already scored under transaction embedding.
The largest independent tower portfolio supports master lease agreements and colocation economics, but tower advantage is site-by-site and local; portfolio size is a modest extra edge over CCI and SBAC.
Buyers are enterprises choosing on switching cost, integration and performance, which the other pillars rate. The name carries reputation, not a price premium it could hold on brand alone.
Moat in 5–10 years
American Tower's moats hold through the next decade. Entitled sites stay scarce because zoning and permitting do not get easier, carrier equipment stays wired into live network topology, and Crown Castle and SBA keep matching the portfolio rather than undercutting it. Tenant churn of the DISH kind is already in the embedding rating. SpaceX is the open question on both sides: a signed macro-site lease would be a fourth national tenant, while a satellite-first carrier that wins subscribers from AT&T, Verizon and T-Mobile (85% of U.S. & Canada property revenue in 2025) could slow their densification. As of October 23, 2026 SpaceX is reported to be in talks for at least 80,000 US sites with nothing signed, too early to call a direction.

Growth Score
Q2 2026 (reported Jul 28, 2026) printed total revenue $2.749B (+4.7%) and property revenue $2.688B (+6.3%). AFFO attributable to AMT common stockholders was $1.264B (+3.8%), or $2.71 per share (+4.2%). Management raised FY2026 AFFO guidance to $5.135–$5.215B / $11.00–$11.17 per share (~3% growth at the midpoint) and framed 2026 as a trough AFFO-growth year: normalized growth is higher ex-DISH and refinancing headwinds, with mid- to high-single-digit AFFO growth expected as those fade into 2027. Organic tenant billings ~2% headline / ~4% ex-DISH; U.S./Canada ~5% ex-DISH. CoreSite/data center property revenue growth guided ~15%. Net leverage ~4.9x, inside the 3–5x target. Philippines and Bangladesh exits closed in Q2.
Valuation Score
At $188.97 (Oct 23, 2026 close), AMT screens about 35% above the $140 bear and about 14% below the $220 base. The stock rose from $166.73 on Oct 8 on two SpaceX headlines: the Grain 800 MHz spectrum deal (Oct 9) and a Bloomberg report that SpaceX is in talks for at least 80,000 US cell sites (Oct 22, after the close; AMT opened Oct 23 at $202 and closed up 4.1%). No lease is signed, so the ladder is unchanged. On the raised FY2026 AFFO midpoint (~$11.09/share) the stock is ~17× 2026 AFFO with a ~3.8% dividend yield. Thin first pass — ladder is AFFO-multiple anchored, not a full NAV build. Full restamp due after the Q3 print on Oct 27, 2026.

Growth Analysis
Growth Drivers
Key Risk
If organic tenant billings ex-DISH fail to re-accelerate toward mid-single digits into 2027 — because carrier consolidation, further churn, or delayed densification offset escalators — the trough-year framing breaks and the 6–9% AFFO CAGR band has to be rewritten lower. A second tenant-side risk: SpaceX, which bought the EchoStar spectrum that DISH's network ran on, is reported (Bloomberg, Oct 22, 2026) to be in talks for at least 80,000 US cell sites but has signed nothing, and in August described a rooftop small-cell design that would not lease towers.
Score Derivation
68.8 base + 1.3 trajectory − 5 risk = 65
Base 68.8 (6–9% AFFO CAGR midpoint 7.5%) + 1.3 trajectory (CoreSite accelerating; organic tenant billings and international stable on an ex-DISH view) + 0 stable margins − 5 moderate risk (carrier consolidation / residual DISH / rates-FX) = 65
Thin First Pass — Open for Restamp
CoreSite / data-center durability (utilization, pricing, AI/cloud mix) not modeled in depth — ~15% property-revenue guide taken as stated
International FX translation and emerging-market rate/FX risk flagged, not quantified site-by-site
DISH churn treated as a known trough item; path of residual DISH and other carrier consolidation not re-underwritten beyond management's 2027 inflection language

Valuation Analysis
Base fair value $220 assumes the DISH/refi trough clears on schedule, AFFO grows mid-single digits into 2027, and the market restores a ~18–20× AFFO multiple on look-through earnings. It carries no SpaceX lease revenue. Live tape $188.97 (Oct 23 close); ~$88B equity value on ~467M diluted shares from the outlook. Not a hire screen — coverage valuation only. $220.
Valuation Multiples
| Price / 2026E AFFO | ~17.0× |
| AFFO yield (2026E) | ~5.9% |
| Dividend yield | ~3.8% |
| Net leverage | ~4.9× |
| Price / Sales (NTM, rough) | ~8.1× |
AMT is being priced closer to a trough-growth REIT than to a scarce-site compounder. If management's 2027 mid/high-single-digit AFFO path prints, ~17× 2026 AFFO leaves upside toward the $220 base. If ex-DISH organic stays muted and CoreSite decelerates, the multiple can compress toward the $140 bear without needing a balance-sheet accident. International FX and CoreSite depth remain the two largest unmodeled swings on this thin pass.
Approximate figures as of October 23, 2026.
Where We Are vs Targets
Loading live price…
DISH overhang lasts longer than guided, ex-DISH organic stays ~2–3%, CoreSite decelerates, and the AFFO multiple compresses toward ~12–13× on a flat 2027.
- Organic tenant billings ex-DISH remain sub-3% through 2027 as carrier consolidation and densification delays offset contractual escalators
- CoreSite growth fades from the ~15% guide toward high-single digits without a clear AI/cloud interconnection ramp
- Rates stay restrictive; refinancing costs keep AFFO growth near the 2026 trough print into 2027
- Multiple compresses to ~12.5× on ~$11 AFFO → ~$140; dividend still covered but the compounder narrative de-rates
2026 is the trough: DISH and refinancing headwinds fade, AFFO returns to mid-single-digit growth in 2027, and the market pays ~18–20× look-through AFFO.
- FY2026 AFFO lands inside $11.00–$11.17; 2027 AFFO/share grows mid-single digits as DISH comps ease
- U.S./Canada organic ex-DISH holds near ~5%; consolidated ex-DISH organic returns toward ~4%+
- CoreSite sustains low-double-digit to ~15% property revenue growth without a leverage break above 5×
- ~19× on ~$11.50–12 look-through AFFO supports ~$220; dividend continues mid-single-digit growth
CoreSite becomes a second growth engine, international FX stabilizes, and AFFO compounds high-single digits — multiple expands back toward prior-cycle scarcity pricing.
- CoreSite outperforms the ~15% guide on interconnection / cloud demand and earns a data-center scarcity premium inside the consolidated multiple
- Post-DISH organic billings surprise toward high-single digits on densification and new-tenant activity
- Leverage trends toward the midpoint of 3–5× while AFFO/share compounds ~8–10% for several years
- Market restores ~22–24× AFFO on growing earnings → ~$280
