Stable cash, sticky churn
- ADT served about 6.1 million security monitoring subscribers at March 31, 2026.
- Gross customer revenue attrition stayed high at 13.1%, with non-payment disconnects still pressuring the base.
- About 40% of new subscribers now buy equipment upfront through the outright sales model.
- ADT Blue opens a lower-cost DIY channel, but it could pull some buyers away from professional installs.
- Origin AI adds camera-free sensing tech, but management does not expect material 2026 revenue from it.
A steadier base, not a fast grower
ADT is a large, mature security company. The good part is that most revenue comes from monthly monitoring fees, which makes the business more predictable than a one-time hardware seller. This recurring monthly revenue is the foundation of the company.
The bull case focuses on making each customer more valuable and cheaper to serve. ADT is pushing ADT+, relying more on upfront equipment sales, using AI in customer service, and growing the new ADT Blue online channel. If ADT Blue brings in new customers, and if some later upgrade to professional installation, growth could improve.
The bear case centers on high customer churn. Gross customer revenue attrition is 13.1%, and non-payment disconnects remain a pressure point. ADT is also intentionally slowing some gross additions by tightening credit standards and pulling back from costly channels, meaning near-term growth can look soft even if customer quality improves.
Origin AI provides a longer-term option. Its sensing technology verifies alarms and creates new smart home features without cameras or wearables. However, ADT does not expect a material revenue impact from Origin AI in 2026, so investors will need proof from pilots before counting on the technology.
Monthly fees carry the model
ADT installs or sells security and smart home equipment, then charges customers for monitoring and related services. That monthly fee stream is the core of the business. ADT notes a typical customer takes about two years to reach revenue break-even after the upfront cost to acquire and install that system.
The model is shifting. Now about 40% of new subscribers are outright sales, meaning the customer owns the equipment and pays more upfront. This helps near-term revenue and cash flow, but it changes the mix away from the traditional company-owned equipment model.
ADT also buys customer portfolios when the price is attractive. This can add subscribers faster than organic sales, but it adds integration risk and can mask weak growth in the dealer channel.
The weak spot remains retention. ADT states a 100 basis point change in customer attrition typically has about a $40 million annualized impact on recurring revenue. That makes the 13.1% attrition rate one of the most important numbers for the company.
From alarms to AI sensing
Professional monitoring
This is the core service. Customers pay recurring fees for alarm monitoring and related support.
ADT+ installed systems
ADT+ is the main platform for new direct residential installs. It ties closely to Google Nest products and supports the shift to upfront equipment sales.
ADT Blue
ADT Blue is a lower-cost DIY line sold online through the ADT website and Amazon. It reaches value-focused buyers, but it may also compete with higher-fee professional installs.
Origin AI sensing
Origin AI uses radio signals and AI to detect presence and activity without cameras, audio, or wearables. ADT recently completed the design of a smart plug for early integration.
Google Nest integration
Google Nest products add smart home features to the ADT offering. They help ADT sell a broader home platform rather than just a basic alarm.
Live Light and My Safety
Live Light is an illuminated yard sign tied to alarm events. My Safety is a mobile personal safety service, giving ADT more ways to sell protection outside the home alarm.
One segment, two revenue lines
ADT reports one operating and reportable segment. The mix shown is early 2026 revenue inside that segment: monitoring and related services, plus security installation, product, and other revenue.
What could break the thesis
Non-payment churn
High impact · High oddsGross customer revenue attrition remains high at 13.1%. While voluntary cancellations improved, non-payment disconnects continue to be a pressure point. A 100 basis point change in attrition typically moves annualized recurring revenue by about $40 million.
ADT Blue cannibalization
Medium impact · Medium oddsADT Blue targets value-conscious DIY customers with lower-cost cameras and online sales. This could bring in customers ADT was missing. However, it could also pull some buyers away from higher-fee professional installations.
Origin AI takes longer than hoped
Medium impact · Medium oddsOrigin AI is central to the technology story, but ADT does not expect material revenue or cost of revenue impact from the acquisition in 2026. The smart plug design shows progress, not proof of customer demand. Delays would push the bull case further out.
Legacy system upgrade friction
High impact · Medium oddsA large part of the ADT installed base still uses legacy systems like ADT Pulse or older burglar alarm hardware. These systems are not compatible with ADT+ and Origin AI features. If customers refuse to pay for upgrades, churn could rise.
Debt limits flexibility
High impact · Medium oddsADT relies on debt to operate. The company is currently executing a large share repurchase plan. If interest rates rise or cash flow declines, debt service can crowd out growth spending.
Apollo influence
Medium impact · Medium oddsApollo owns a significant portion of ADT common stock and keeps board nomination rights. Governance risk matters when the company makes big choices on buybacks, debt, and acquisitions.
In one breath
How does ADT make most of its money?
ADT makes most of its money from recurring monthly monitoring and related service fees. It also earns revenue when it installs or sells security and smart home equipment.
What is ADT Blue?
ADT Blue is the new lower-cost DIY product line sold through e-commerce. The goal is to reach buyers who may not want a full professional install at first.
Why is ADT's attrition rate important?
Attrition shows how much recurring revenue ADT loses when customers cancel or stop paying. ADT reports 13.1% gross customer revenue attrition, and even small changes impact the bottom line significantly.
Is Origin AI helping ADT revenue now?
Not in a material way yet. ADT states it does not expect a material revenue or cost of revenue impact from Origin AI during 2026, so this is mainly a 2027 proof point.
