Security monitoring subscriber system asset expenditures measure cash invested in equipment and installation costs for customer systems that ADT retains on its balance sheet.

ADT reported $396.0 million of subscriber system asset expenditures in 2025, down from $523.1 million in 2024.

The spending belongs to the company-owned acquisition model

When ADT retains ownership of a security system, equipment and installation costs are capitalized rather than treated like the cost of an outright system sale.

The cash outflow therefore helps fund subscriber system assets tied to monitoring relationships whose economics are expected to be recovered over time.

The expenditure is not ordinary property-and-equipment capex

ADT separately reported $175.7 million of purchases of property and equipment in 2025.

Subscriber system asset expenditures are a distinct investing cash-flow line tied directly to customer systems.

Lower spending can affect cash flow before accounting expense changes

Subscriber system asset expenditures fell by roughly $127 million year over year, while subscriber system asset depreciation was still about $550 million.

That timing difference is expected because current cash investment and depreciation of accumulated historical pools measure different periods of the acquisition cycle.

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.

Where this concept fits

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.
