Tower new-site tenant billings are billings attached to communications sites that were built or acquired after the start of the comparable prior-year period.

American Tower reported $13M of new-site tenant billings in the second quarter of 2026, compared with $10M in the prior-year bridge.

Day-one billings are separated from later organic activity

American Tower assigns the initial billing contribution from a newly built or acquired site to new-site tenant billings. Later colocations, amendments, escalations, or cancellations on that site move into the organic bucket after the site enters the portfolio.

That prevents organic tenant billings growth from simply becoming a proxy for acquisition and construction activity.

New sites can grow revenue without proving existing-site demand

A tower operator can add revenue by acquiring or constructing more assets even when leasing activity on the existing portfolio is weak.

That is why investors should separate new-site billings from colocation and amendment billings. The former reflects portfolio expansion; the latter tests incremental monetization of sites already owned.

Part of the Wireless Tower Leasing Economics

Connects recurring tower tenant billings with existing-site leasing, contract escalators, churn, new-site contribution, accounting normalization, site-level cash margins, and recurring maintenance intensity.

Where this concept fits
  • Recurring billings, new sites, and accounting presentationCurrent relationship
    Tenant billings capture recurring contractual lease economics, new-site tenant billings isolate the day-one contribution from constructed or acquired sites, and site-rental billings versus GAAP revenue separates the operating lease base from straight-line and other accounting effects.

  • Existing-site leasing, escalators, and churn
    Colocations and amendments add recurring billings to existing towers, contractual escalators lift rates on leases already in place, and churn removes billings through cancellations, non-renewals, or repricing. Core leasing activity and organic tenant billings growth summarize different issuer-defined views of that same operating engine.

  • Site-level cash economics and reinvestment
    Tower cash flow margin shows the high site-level profitability of the leasing model after direct tower operating costs, while maintenance capex shows the recurring physical reinvestment needed to keep the installed infrastructure productive.
