American Tower (AMT) Q2 2023: International Tower Growth Hits 8.5% as Data Center Backlog Surges 70%
American Tower’s Q2 revealed a step-change in international organic growth and accelerating momentum in its CoreSite data center business. Strategic capital allocation, disciplined contract structures, and a robust global tenant mix are fortifying AMT’s long-term growth profile even as U.S. carrier activity normalizes. Investors should watch for continued margin expansion, India asset resolution, and data center capital requirements as secular demand for connectivity and compute intensifies.
Summary
- International Tenant Billings Accelerate: Africa, Europe, and APAC delivered record organic growth, offsetting U.S. service moderation.
- CoreSite Data Center Demand Outpaces Supply: Backlog and pricing both surged, driving double-digit yield confidence.
- Capital Allocation Remains Disciplined: Deleveraging and selective investment take priority over M&A amid uncertain rate environment.
Business Overview
American Tower (AMT) is a global REIT (real estate investment trust) specializing in wireless communications infrastructure. Its core business is leasing space on towers and data centers to mobile network operators (MNOs) and enterprise/cloud customers. Major segments include U.S. and Canada towers, international towers (across Latin America, Europe, Africa, and Asia-Pacific), and the CoreSite data center platform. Revenue is primarily generated through long-term, inflation-linked contracts with leading carriers and cloud service providers.
Performance Analysis
Q2 results highlighted robust organic tenant billings growth of 6.2% consolidated, led by international outperformance. Africa posted a record 12.9% growth, Europe accelerated to 8.3%, and APAC reached its highest mark since 2017 at 5.6%. Latin America decelerated as expected, with churn timing driving some volatility. U.S. and Canada towers held steady, with organic growth of 5.1% (6.5% excluding Sprint churn).
CoreSite, AMT’s data center arm, continued to outpace expectations. Leasing volumes and backlog surged, with the pipeline up 70% and pricing up 15% year-over-year. Interconnection revenue grew approximately 10%, and renewal rates reached 7%, well above historical averages. This strength supported property revenue growth of over 4% in the quarter, and margin expansion to 63.1% (normalized for India VIL reserves).
- International Growth Diversification: Nearly 45% of property revenue and 36% of operating profit now stem from international assets, with CPI-linked escalators protecting growth.
- Cost Controls Offset Service Slowdown: Cash SG&A held flat, supporting margin expansion despite a pullback in U.S. carrier services.
- Data Center Development Drives Returns: Pre-leasing at 36% and high backlog de-risk capital deployment, with CoreSite yields exceeding underwriting.
Adjusted EBITDA grew nearly 5% (6% FX-neutral), while AFFO per share dipped modestly due to higher interest expense. Balance sheet strength improved as AMT raised $2.7 billion in fixed-rate debt, reducing floating exposure and progressing toward its deleveraging target.
Executive Commentary
"Simply put, the ongoing demand trends in the data center space and the emergence of generative AI use cases are providing American Tower and CoreSite an opportunity to play a central role as an infrastructure provider against a backdrop of technology evolution that's expected to drive a step-up function increase in computing power demand."
Tom Bartlett, President and CEO
"We are maintaining a strong focus on cost management. Once again, in Q2, despite an elevated inflationary environment, we kept cash SG&A roughly flat year over year, helping to support an adjusted EBITDA margin expansion of approximately 60 basis points to 63.1%."
Rod Smith, Executive Vice President, CFO and Treasurer
Strategic Positioning
1. International Portfolio Optimization
AMT’s disciplined country selection and contract structuring are yielding high-quality, predictable growth. Recent divestitures in Mexico fiber and Poland, and the strategic review of India, reflect ongoing portfolio pruning. The international customer base has been reset to focus on leading MNOs, with over 80-90% of revenue in key regions now from market leaders, up significantly from five years ago.
2. Data Center Expansion and Ecosystem Strength
CoreSite’s interconnection-rich campuses are positioned as hubs for hybrid IT and AI workloads, with demand outstripping supply and pricing power evident. AMT is investing $360 million in CoreSite capex this year, mostly funded by the business’s own cash flow, to support record backlog and future AI-driven use cases.
3. Capital Allocation and Deleveraging
Deleveraging is prioritized over M&A, with net leverage targeted below five times and floating rate debt reduced to 15%. Management is open to opportunistic buybacks once leverage targets are achieved and rate uncertainty stabilizes. Dividends and new build programs remain core capital priorities.
4. Margin Expansion and Operating Leverage
Global business services and procurement initiatives are driving productivity and cost optimization, with standardization in lease management and energy procurement yielding annual run-rate savings. These efforts are expected to further expand margins as scale increases.
5. Sustainability and Power-as-a-Service in Africa
AMT’s $345 million investment in solar and battery solutions in Africa is reducing diesel consumption and emissions intensity, while providing a differentiated, high-return service for MNOs. The program supports both customer sustainability goals and AMT’s science-based targets.
Key Considerations
This quarter underscores AMT’s ability to blend global diversification with operational discipline, as the company leans into secular connectivity and compute demand while protecting margins and shareholder returns.
Key Considerations:
- International Growth Quality: Contract structures (CPI-linked escalators, leading MNOs) are insulating AMT from regional volatility and supporting above-average organic growth.
- Data Center Secular Tailwind: AI and hybrid cloud are driving demand for high-density, interconnected data center space, supporting both pricing and backlog.
- Capital Allocation Discipline: Deleveraging and selective capex take precedence over M&A, reflecting a cautious approach in a high-rate environment.
- India Asset Resolution: Strategic review of India is in late stages, with a potential majority stake sale (50–100%) expected in the second half, which could unlock capital and reduce risk.
- Churn Timing: Latin America and Africa churn delays are boosting near-term organic growth, but remain a timing issue not a structural reduction in long-term churn expectations.
Risks
Key risks include macroeconomic volatility (especially FX in emerging markets), interest rate uncertainty, and carrier capex cycles. India remains a material exposure, with $2.5 billion on the books and ongoing strategic review. U.S. carrier activity has moderated, but AMT’s comprehensive MLAs provide protection against near-term fluctuations. Data center capital intensity could rise if AI-driven demand accelerates faster than anticipated, requiring careful balance of growth and returns.
Forward Outlook
For Q3 2023, American Tower guided to:
- Continued strong organic tenant billings growth, especially internationally
- Stable CoreSite data center demand and backlog conversion
For full-year 2023, management raised guidance:
- Property revenue and adjusted EBITDA up by $125 million and $75 million, respectively
- International organic tenant billings growth targets increased for Europe (to 8%) and Africa (to greater than 11%)
Management highlighted several factors that will shape the back half:
- India asset process is in late stages, with a transaction expected in H2
- Data center capex will remain elevated to support robust backlog and AI demand
Takeaways
AMT’s Q2 demonstrated the advantages of global scale, contract discipline, and secular tailwinds in both towers and data centers.
- International Outperformance: Africa and Europe organic growth is well above historical averages, validating AMT’s customer and contract strategy.
- Data Center Leverage: CoreSite’s backlog and pricing power are translating into higher returns and capital deployment confidence.
- Watch India and Capital Allocation: Investors should monitor the India resolution and data center capex trajectory as the next major drivers of risk and upside.
Conclusion
American Tower’s diversified global platform is delivering resilient growth, with international towers and CoreSite data centers both outperforming expectations. Prudent capital allocation and margin discipline are positioning AMT to benefit from the next wave of connectivity and compute demand while managing risk in a dynamic macro environment.
