American Tower Corporation (REI (AMT) Stock Price & How to Invest

American Tower Corporation (NYSE: AMT), founded in 1995 and headquartered in Boston, is a real estate investment trust that owns, operates, and develops multitenant communications real estate. Its core business is leasing vertical space on wireless towers to mobile network operators, government agencies, and broadcasters under long-term contracts with annual escalators, generating 97% of 2025 revenue from property operations. Beyond towers, AMT owns CoreSite, a portfolio of 30 U.S. data centers offering colocation and interconnection services to enterprises, cloud providers, and network operators, which has become a fast-growing second revenue engine. The company manages nearly 150,000 communications sites across the Americas, Europe, Africa, and Asia-Pacific, providing global scale that smaller peers cannot easily replicate.

American Tower converted to REIT status in 2012 and spent much of the 2010s on aggressive international expansion, building or acquiring towers across Africa, India, Latin America, and Europe. The company acquired CoreSite Realty in 2022 to diversify into data centers. It divested its India operations (ATC TIPL) in late 2024, streamlining the portfolio. CEO Steven Vondran, who took the helm in 2023, has focused the strategy on cost discipline, balance-sheet deleveraging (net leverage declined to 4.9x by year-end 2025), and durable AFFO per share growth. The leadership team is executing a 2026 plan centered on tower leasing momentum, CoreSite expansion, and new cost efficiency initiatives.

The most immediate risk is customer concentration: in 2025, four carriers (T-Mobile at 18%, AT&T at 17%, Verizon at 14%, and Telefonica at 10%) collectively represented roughly 59% of total revenue, so any material lease dispute, consolidation event, or technology shift (such as carriers building private networks or relying on low-earth-orbit satellites) could disproportionately hurt results. AMT carries $37.2 billion in consolidated debt, meaning its cost of capital is sensitive to interest rate levels, and the net leverage ratio of 4.9x leaves limited buffer if earnings disappoint. Foreign currency volatility is a persistent drag given the company's large international portfolio, and regulatory or political instability in emerging markets (as seen with certain Latin American customer events in 2025) can disrupt anticipated cash flows. Finally, the tower industry faces longer-term structural questions about whether continued 5G spending by carriers will generate the densification cycle that bulls expect, given that some analysts describe 5G as having thus far underwhelmed relative to early projections.

23 analysts publish price targets on AMT, averaging $215.48 against a $173.36 price as of August 2026, or +24.3%. The published targets run from $188.00 to $260.00, a moderate spread, and the ratings split 21 buy, 4 hold, 0 sell. Over the last six months there have been 6 raises and 2 cuts among the published actions. A price target is what an analyst published on a date, not a prediction, and sell-side ratings skew positive across the whole market.

We give no verdict on American Tower Corporation (REI. Both cases are real, which is why the question is contested at all, so here is the strongest version of each.

The case for buying. 5G Densification and Mid-Band Upgrades. U.S. The most optimistic published target, $260.00, assumes this works close to its best case.

The case against. The most immediate risk is customer concentration: in 2025, four carriers (T-Mobile at 18%, AT&T at 17%, Verizon at 14%, and Telefonica at 10%) collectively represented roughly 59% of total revenue, so any material lease dispute, consolidation event, or technology shift (such as carriers building private networks or relying on low-earth-orbit satellites) could disproportionately hurt results. The most pessimistic target, $188.00, is roughly what AMT is worth if this bites instead.

A simple financial snapshot. These are approximations and refresh quarterly; for current figures see American Tower Corporation (REI's investor relations page or your broker.

• Revenue (Q1 2026): ~$2.74 billion
• Revenue (FY 2024, most recent full year): ~$10.13 billion
• Adjusted EBITDA (Q1 2026): ~$1.84 billion (margin ~67%)
• AFFO per Share (Q1 2026): ~$2.84 (up ~3.3% year-over-year)
• Trailing P/E Ratio: ~27x (as of late June 2026)
• Forward P/E Ratio: ~26.8x (as of June 21, 2026)
• EPS (TTM): ~$6.19
• Consolidated Debt (year-end 2025): ~$37.2 billion; Net Leverage ~4.9x

AMT's trailing P/E of approximately 27x is well below its own 3-year average of roughly 45x and its 10-year average of roughly 56x, reflecting both earnings normalization after a period of large one-time items and a broader re-rating of rate-sensitive REITs in a higher-for-longer interest rate environment. For tower REITs, investors typically focus on AFFO per share rather than GAAP earnings, because the latter is heavily influenced by depreciation and one-time currency gains or losses. On that basis, FY 2025 delivered high-single-digit AFFO per share growth, and management's 2026 guidance projects continued quarterly revenue in the $2.67 billion to $2.77 billion range per quarter, suggesting mid-single-digit full-year growth if realized.

If you want AMT exposure as part of a larger bundle rather than directly, these ETFs hold it meaningfully. Weights are approximate and refresh quarterly.

These are the investment theses AMT naturally fits into. Each links to a full theme guide listing every other stock that belongs and the ETFs commonly used as a passive proxy.

Other names that sit close to AMT: same theme, named as a direct competitor, or held beside it in the same funds. Each entry says which. Worth a look if you are thinking about diversification within a thesis rather than concentration on one ticker.

There are three common ways to get AMT exposure. Buy shares (or fractional shares) directly at any major broker. Hold an ETF that includes it (VNQ, SCHH, XLRE), which spreads the position across many companies. Or build it into a focused thematic portfolio, so AMT sits alongside other stocks that express the same thesis.

Walnut takes the portfolio route. Describe a thesis where AMT fits (for example “AI infrastructure” or “dividend-growth large-caps”) and the AI proposes 5 to 6 constituents with target weights. You review the plan and fund it through your own broker when you're ready.

AMT is a toll-road on global wireless data growth: it collects long-term, escalator-linked rents from carriers who have no practical alternative to its towers, while its CoreSite data center segment posted double-digit revenue growth in 2025, fueled by AI and hybrid-cloud demand. Q1 2026 total revenue rose 6.8% year-over-year to approximately $2.74 billion, suggesting the business has re-accelerated after a multi-year period of carrier consolidation headwinds. If you believe that 5G densification, international 4G/5G upgrades, and AI-driven data center demand will sustain mid-single-digit to high-single-digit cash-flow growth for years, the question becomes sizing and overlap with other infrastructure REITs, not timing; the risk is that $37.2 billion in consolidated debt leaves limited room for error if interest rates stay elevated or if a top carrier significantly reduces its tower footprint.

Whether AMT is worth buying today depends more on your time horizon and what you already hold than on any single call. We walk through valuation, what would have to go right, and the risks in is AMT a buy or a sell?, and where the stock could go from here in the AMT stock forecast.
