AMT vs PLD: How American Tower Corporation and Prologis Compare (2026)

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.

Prologis (NYSE: PLD) is a self-administered, self-managed real estate investment trust focused exclusively on industrial and logistics properties. The company owns and operates approximately 1.3 billion square feet across roughly 5,882 buildings in 20 countries, with a strong concentration in high-barrier, last-mile markets in North America, Europe, and Asia. Revenue comes primarily from long-term leases on warehouse, distribution center, and fulfillment facility space, supplemented by a Strategic Capital segment that manages approximately $60 billion in third-party assets on behalf of institutional co-investment partners. Rental income is the dominant and most stable revenue stream, while strategic capital fees (including periodic promote income) add a more variable layer of earnings.

Both fit overlapping themes, but they are not interchangeable. American Tower Corporation is best understood through its own drivers, and Prologis through its. 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.
• PLD drivers: E-Commerce as a Structural Tailwind; Reshoring and Supply Chain Reconfiguration.

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.

PLD. For industrial REITs, Core Funds from Operations (Core FFO) is a more relevant cash-flow metric than GAAP net earnings, as GAAP figures are affected by depreciation, gains on property sales, and promote income timing. PLD's trailing GAAP P/E of approximately 37x is roughly 50% above the broader real estate sector average, reflecting the market's premium for its scale, portfolio quality, and long-term demand drivers. The dividend payout ratio on a GAAP earnings basis exceeds 100%, which is normal for REITs given depreciation, but coverage on a Core FFO basis remains comfortable.

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%); PLD shows revenue (full year 2025) ~$8.79 billion, net earnings attributable to common stockholders (fy2025) ~$3.32 billion, core ffo per diluted share (fy2024, most recent full-year figure) ~$5.56. A cheaper-looking multiple is not automatically the better buy: a richer valuation can be justified by faster growth, and a lower one can reflect real risk. Weigh the multiple against how fast each business is actually compounding.

Both share a theme, but they suit different temperaments. American Tower Corporation's case leans on 5g densification and mid-band upgrades, and Prologis's on e-commerce as a structural tailwind. 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 PLD, the primary bear case centers on the interest rate environment: Prologis carries a debt-to-EBITDA ratio near 5x, and sustained elevated rates could raise refinancing costs, expand capitalization rates, and compress net asset values even if occupancy holds.

Pick AMT if you believe its drivers more; PLD 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 PLD guides.

AMT and PLD 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 PLD exposure against your real portfolio. It is not an investment adviser.
