Tower organic tenant billings growth measures recurring billings growth generated by the installed site portfolio rather than day-one contribution from newly built or acquired sites.

American Tower reported $34M, or 1.7%, of organic tenant billings growth in the second quarter of 2026.

The bridge is leasing plus escalators minus churn

American Tower's quarter included $63M of colocations and amendments, $64M of escalations, and $92M of cancellations, plus a small other adjustment.

That makes organic growth an operating bridge, not a single demand statistic. Contractual rent escalators can partly offset weaker leasing, while tenant churn can overwhelm otherwise healthy additions.

Comparable tower metrics still need issuer definitions

Crown Castle reported adjusted Organic Contribution to Site Rental Billings of 4.2% in Q2 2026 after excluding DISH revenue from the prior-year base and isolating large DISH and Sprint terminations. Its unadjusted organic contribution was negative.

The concepts are economically related, but the scope and special adjustments differ. Preserve those definitions before comparing peers, and keep new-site tenant billings outside the existing-site growth read.

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
  • Existing-site leasing, escalators, and churnCurrent relationship
    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.

  • Recurring billings, new sites, and accounting presentation
    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.

  • 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.
