ADT (ADT) Stock Analysis & Winston Score
ADT Inc. is a home and business security company. It sells alarm systems, cameras, smart locks, and monitoring services to homeowners and small businesses across the United States. ADT is one of the oldest and largest security brands in the country, with roots going back to 1874. ADT makes most of its money through recurring monthly fees that customers pay for professional monitoring — meaning ADT watches for break-ins, fires, and other emergencies around the clock. The company operates almost entirely in the U.S. and has roughly 6 million customers under contract. Its main competitive advantage is its large installed base and brand recognition, though it faces growing competition from cheaper DIY options like Ring and SimpliSafe. The key risk is customer cancellations, called "attrition," which can be costly because ADT spends heavily upfront to install equipment before earning back that cost over time through monthly fees.
