AMT vs WELL: How American Tower Corporation and Welltower Compare (2026)

Same yardstick, side by side (as of July 2026). Valuation lined up like this is most meaningful for two names in the same corner of the market, which these are. Figures are approximate; verify before investing.

Reading it: AMT is the cheaper of the two on forward earnings, but cheaper is not the same as better. Pair the valuation with growth (how far the forward P/E sits below the trailing P/E) and risk (beta) before you decide.

The metrics above tell you which is the marginally better business. The bigger risk for most people is not picking the slightly worse stock, it is over-concentrating. AMT and WELL share themes, so owning both, or adding either to what you already hold, can quietly push a large share of your portfolio into one bet.

This is the part a generic comparison page cannot answer, because it depends on what you own. Connect your brokerage and Walnut shows your real, combined AMT and WELL exposure, flags overlap with your existing positions, and tells you if adding one would tip you past a concentration you are comfortable with, read-only by default, with your login staying at your broker.

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.

Welltower Inc. is the largest healthcare REIT in the world, owning a portfolio of senior housing, assisted living, post-acute and long-term care, and outpatient medical real estate across the United States, the United Kingdom, and Canada. It makes money in two main ways: through its Senior Housing Operating Portfolio (SHOP), where it shares directly in the net operating income that property operators generate from residents, and through rents on triple-net leased seniors housing and care facilities plus outpatient medical buildings. Because SHOP income flows through to Welltower rather than being fixed rent, rising occupancy and room rates translate quickly into higher earnings, which is why the operating portfolio has become the company's main growth engine.

Both fit overlapping themes, but they are not interchangeable. The useful comparison is which set of drivers and risks you want exposure to.

• AMT drivers: 5G Densification and Mid-Band Upgrades; CoreSite and AI-Driven Data Center Demand.
• WELL drivers: Aging-demographics senior-housing tailwind; Operating-portfolio NOI growth.

A faster-growing, richer-valued name usually swings harder, so it suits a longer horizon and a higher tolerance for volatility; a steadier, more cash-generative business suits a more conservative or income-minded investor. The honest test is which set of risks you could hold through a drawdown: 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. For WELL, welltower's share price is sensitive to interest rates, since higher rates raise borrowing costs and make REIT dividend yields less competitive against bonds.

Growth-minded investors who believe the theme has years to run tend to accept the richer multiple for more upside; value-minded investors lean toward the cheaper forward earnings and steadier profile. Pick AMT if you believe its drivers more; WELL if you believe its. Many investors hold both, but since they share themes, that is a concentrated bet, not diversification. Decide deliberately and check overlap. For the full detail, see the AMT and WELL guides.

AMT. 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.

WELL. Healthcare REITs are valued on funds from operations (FFO) rather than EPS, because standard net income is weighed down by large non-cash depreciation charges on real estate. For Welltower the most important operating metric is same-store NOI growth in the Senior Housing Operating Portfolio, since that captures how much extra income the company earns as occupancy and room rates rise. Welltower trades at a notably higher FFO multiple, and a lower dividend yield, than most healthcare REIT peers, reflecting the market's confidence in its senior-housing growth, its scale, and its balance sheet; that premium is part of the investment case and part of the risk.

Headline figures (approximate, 2026-06-27): AMT shows 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); WELL shows normalized ffo per share (2025) $5.29 (+~22.5%), 2026 normalized ffo guidance $6.09 to $6.25, shop same-store noi growth (q4 2025) ~20.4% YoY, revenue (2025) ~$10.84 billion (+~36%).

AMT and WELL are related but distinct: same themes, different businesses and risks. Neither wins in the abstract; the right pick is whichever thesis you actually believe, sized so you are not over-concentrated in one theme. Walnut can show your combined AMT and WELL exposure against your real portfolio. It is not an investment adviser.
