Resideo Technologies, Inc. (NYSE: REZI) is a global provider of technology-driven products and solutions for homes and businesses. The company makes and distributes the everyday devices that help manage indoor comfort, energy use, safety, and security — including thermostats, smoke and carbon monoxide detectors, security systems, and water-leak sensors. Investors follow REZI because it sits at the intersection of the long-established heating, ventilation, and air conditioning (HVAC) industry and the faster-growing connected-home and smart-building markets.
Resideo was incorporated in 2018, when Honeywell International spun off its Homes and ADI Global Distribution businesses as part of a restructuring. The new company began trading on the New York Stock Exchange in October 2018 under the ticker REZI. Although Resideo itself is young, its operating heritage stretches back more than a century through the legacy home-comfort, safety, and security businesses it inherited. The company is headquartered in Scottsdale, Arizona, and reports a workforce of roughly 14,800 employees, with products installed in more than 150 million locations worldwide.
Resideo's business model is built on two complementary segments. The Products & Solutions segment develops and manufactures temperature and humidity controls, water and air solutions, smoke and carbon monoxide detection products, residential and small-business security products, video cameras, and related software and cloud services. These products are sold under brands including Honeywell Home, First Alert, BRK, Resideo, and Braukmann.
The ADI Global Distribution segment is a wholesale distributor of low-voltage security, life-safety, access-control, and audio-visual products. ADI serves professional installers and integrators through a physical branch network supplemented by digital and e-commerce channels. In 2024, Resideo expanded this segment by acquiring Snap One, a provider of smart-living products and home-automation solutions, for approximately $1.4 billion, adding the Control4 brand to its portfolio.
Resideo generates revenue primarily by selling its products through professional contractors, installers, integrators, and distributors, as well as through retailers and online merchants. Its competitive position rests on trusted brands, deep relationships with professional installers, and a broad installed base of homes and buildings that drives recurring replacement and upgrade demand. In 2025, the company reported revenue of approximately $7.5 billion.
Resideo attracts investor attention because it combines a stable, non-discretionary product base with exposure to structural growth in connected-home technology. Thermostats, smoke detectors, and security systems are essential building components that must be maintained and replaced over time, providing a relatively steady demand foundation even in uncertain economic conditions.
The company's competitive advantages include its recognized brand portfolio, a vast installed base of more than 150 million locations, and long-standing relationships with professional installers who specify and deploy its products. Resideo has also pursued a strategy of product differentiation and margin expansion, refreshing its thermostat lineup and launching connected safety devices aimed at the smart-home market.
A notable strategic development is the company's announced plan to spin off its ADI Global Distribution business as a separate publicly traded entity. Resideo has described this move as a way to create a more focused, "pure-play" building-technologies company centered on its sensing, controls, and safety portfolio. Investors following REZI are therefore also monitoring how this separation reshapes the company's long-term growth and financial profile.
Several factors are worth understanding before investing. Resideo's business is closely tied to residential and commercial construction and renovation activity, making it sensitive to housing-market cycles, interest rates, and consumer spending. Higher interest rates or a slowdown in new construction and remodeling can weigh on demand for its products.
The company also faces competition from large industrial and technology firms in thermostats, security, and smart-home devices. Its Honeywell Home brand is used under a long-term licensing agreement, which creates dependence on an arrangement with a former parent company. Additionally, the planned separation of ADI Global Distribution introduces execution and transition risks, including the costs and complexity of splitting shared systems, allocating liabilities, and establishing standalone operations. As with any industrial company, Resideo is also exposed to supply-chain disruptions, input-cost inflation, and regulatory changes affecting safety and energy standards.

Resideo Technologies is a distinctive company that bridges traditional building infrastructure and modern connected-home technology. Its portfolio of trusted brands, large installed base, and dual manufacturing-and-distribution model give it a meaningful position in comfort, safety, and security markets. As the company moves toward a more focused structure following the planned ADI separation, REZI remains a relevant name for investors interested in the long-term dynamics of residential replacement demand and the broader smart-building trend.
