Security monitoring deferred subscriber acquisition revenue amortization measures revenue recognized during the period from upfront subscriber-acquisition fees that were deferred in earlier customer transactions.

ADT recognized $358.4 million of deferred subscriber acquisition revenue amortization in 2025, up from $346.2 million in 2024.

The revenue can be recognized long after the original cash receipt

The underlying fees are collected in company-owned transactions but recorded as deferred subscriber acquisition revenue because ADT treats them as part of a material right associated with the monitoring relationship.

Revenue recognition then follows the estimated customer-life pattern rather than the original billing date.

The amortization is accelerated

ADT uses the same pooled accelerated method applied to subscriber system assets and deferred acquisition costs.

That means more of the deferred balance is generally recognized earlier in the estimated customer relationship than under straight-line recognition.

Do not confuse revenue amortization with cost amortization

ADT also recorded $252.6 million of amortization of deferred subscriber acquisition costs in 2025.

One line recognizes previously deferred revenue; the other recognizes previously capitalized selling costs. They affect different parts of the income statement and should not be netted conceptually.

Outright-sale installation revenue is recognized differently from company-owned upfront fees, while deferred subscriber acquisition revenue and remaining performance obligations show how existing customer contracts feed later revenue recognition.

Subscriber base, recurring revenue, retention, and payback
Subscriber count supplies the installed base, RMR and recognized recurring revenue describe monetization, attrition measures recurring revenue lost, and payback connects the upfront acquisition investment to the revenue stream that recovers it.
