American Tower Lifts Outlook Amid Data Center Surge

American Tower Corporation ((AMT)) has held its Q1 earnings call. Read on for the main highlights of the call.

American Tower’s latest earnings call struck a cautiously upbeat tone as management raised full‑year guidance despite several near‑term headwinds. Executives pointed to strong data‑center momentum, resilient international growth and a solid balance sheet as reasons for confidence, while acknowledging that DISH churn, Brazil weakness and margin compression are weighing on near‑term results.

Raised Outlook Signals Growing Confidence

American Tower lifted its full‑year guidance across property revenue, adjusted EBITDA and AFFO per share by about 1% at the midpoint. The upgrade was driven mainly by a favorable FX tailwind of roughly $110 million and about $35 million of accelerated noncash straight‑line revenue, underscoring improving visibility despite operational noise.

Steady Core Growth Behind the Headline Numbers

Consolidated property revenue rose about 3% year over year after stripping out noncash straight‑line and FX effects. On a cash FX‑neutral basis and excluding one‑time DISH churn, normalized growth was closer to 5%, with organic tenant billings up roughly 2% or around 4% when the DISH impact is removed.

CoreSite Data Centers Outperform Expectations

CoreSite again emerged as a standout with about 17% cash property revenue growth in the quarter excluding straight‑line. Management highlighted an inflection in interconnection activity and reiterated roughly 13% data‑center property revenue growth for the year, calling CoreSite a high‑margin, differentiated platform exceeding original expectations.

Africa and APAC Drive Robust Expansion

Africa and APAC delivered about 11% organic growth in the quarter, making these regions among the strongest contributors to overall tenant billings. The performance underscores the structural demand for mobile data and network upgrades in emerging markets, offsetting softness in other geographies.

Europe Surpasses Deal Underwriting

In Europe, organic growth of roughly 4% continued to run ahead of assumptions baked into the Telefonica acquisition. American Tower plans more than 700 new site builds in the region, targeting returns several hundred basis points above the local cost of capital and reinforcing Europe as a key long‑term growth engine.

Efficiency Efforts and Long‑Term Margin Ambitions

Management reported progress in lowering direct tower costs through better land terms, maintenance, sourcing and internal technology initiatives. The company remains confident in achieving 200 to 300 basis points of cash adjusted EBITDA margin expansion in its tower business by 2030 and is exploring AI tools to further accelerate efficiency gains.

Capital Allocation Stays Disciplined and Shareholder‑Friendly

Roughly 85% of discretionary capital is being directed to developed markets and CoreSite, including more than $700 million slated for success‑based data‑center investments and land purchases under towers. American Tower also leaned into buybacks, repurchasing about $184 million of stock in the first quarter and another $19 million through late April, with total repurchases since Q4 topping $565 million.

Balance Sheet Strength and Expanding Development Pipeline

The company ended the quarter with leverage near 4.9 times and the highest credit rating in its peer group, giving it funding flexibility in a volatile rate environment. CoreSite’s development pipeline also expanded, with held development power of roughly 287 MW and about 200 MW of additional available capacity supported by ongoing land and power acquisitions.

DISH Churn Creates One‑Time Earnings Drag

A one‑time churn event related to DISH materially depressed reported results, creating roughly a 400‑basis‑point headwind to AFFO growth. Management is effectively normalizing its outlook by excluding DISH and FX effects to “derisk” guidance, but investors should recognize reported metrics remain meaningfully below these adjusted figures.

Brazil‑Driven Weakness in Latin America

Latin America posted about a 2% decline in organic tenant billings as elevated churn in Brazil weighed on regional performance. Management framed this as a timing issue and expects market repair to begin around 2027, with more normalized growth returning by 2028, implying several years of softer trends.

Margin Compression Highlights Near‑Term Pressure

Cash adjusted EBITDA margins slipped about 110 basis points year over year in the quarter. The decline was tied mainly to DISH churn, the timing of SG&A spending and higher fuel costs in Africa, signaling that the path to longer‑term margin expansion will not be linear.

AFFO Per Share Under Pressure, but Normalized Growth Intact

Attributable AFFO per share fell roughly 1% excluding FX in the quarter, though it would have grown about 4% on an FX‑neutral basis excluding DISH and refinancing costs. Management highlighted several headwinds for 2026 AFFO, including FX, refinancing and services, which together represent around 400 basis points of pressure despite underlying mid‑single‑digit growth.

Permitting and Community Pushback on Data Centers

The company flagged rising local opposition and permitting challenges for data‑center builds, citing examples in markets such as North Carolina. Dedicated government affairs and permitting teams are being deployed to manage this NIMBY risk, though management acknowledged timelines for some projects could slip if resistance intensifies.

Churn Timing Fuels Near‑Term Volatility

Executives warned that churn timing will introduce volatility into quarterly results, with 2026 likely to see elevated churn as events slip from 2025 and pull forward from 2027. This lumpiness will affect both regions and metrics but is viewed as a timing issue rather than a change in underlying demand.

Guidance Points to Normalized Mid‑Single‑Digit AFFO Growth

The updated outlook calls for roughly 3% reported property revenue growth excluding straight‑line and FX, or about 5% on a cash FX‑neutral basis when adjusted for DISH churn. Adjusted EBITDA is expected to grow about 2% reported, or roughly 5% FX‑neutral excluding DISH, while AFFO per share guidance of about $10.99 implies around 2% reported growth and close to 5% FX‑neutral growth after stripping out DISH and refinancing costs.

American Tower’s earnings call painted a picture of a company navigating temporary turbulence while leaning into secular growth drivers from mobile data, 5G and AI‑linked data‑center demand. For investors, the narrative is one of modest near‑term pressure offset by rising guidance, strong data‑center and international trends, disciplined capital deployment and a balance sheet positioned to support long‑term AFFO expansion.
