Security monitoring deferred subscriber acquisition cost amortization measures the income-statement expense recognized from selling costs that were capitalized when customers were acquired.

ADT recorded $252.6 million of amortization in 2025, up from $224.6 million in 2024.

The expense is delayed relative to the original commission spending

ADT capitalizes incremental selling expenses, primarily commissions, when customers are acquired.

Those costs then move through SG&A over the estimated customer relationship rather than being expensed entirely when the sale occurs.

The amortization is front-loaded

ADT applies an accelerated method over an estimated 15-year customer relationship.

The same pooled methodology is used for subscriber system assets, with approximately 55% of the pool recognized in the first five years.

Do not compare amortization directly with current acquisition cash spend

Amortization reflects historical acquisition pools.

Current subscriber-acquisition investment can include commissions, company-owned system expenditures, and dealer account purchases that follow different cash-flow and accounting treatment.

This metric is therefore an accounting recognition measure, not a cash acquisition-cost metric.

Part of the Security Monitoring Subscription Economics

Connects monitoring subscriber scale and retention with recurring revenue, subscriber-acquisition investment, company-owned system economics, and the deferred and contracted revenue created by long-duration monitoring relationships.

Subscriber acquisition and company-owned system investmentCurrent relationship
Dealer account purchases and contract additions acquire customer relationships, while subscriber system assets and deferred acquisition costs capitalize different parts of the investment required to create and support monitoring subscribers.

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.

Installation, deferred fees, and contracted future service revenue
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.
