Overview
Resideo Technologies, Inc. is an American publicly traded company that designs, manufactures, and distributes products for residential comfort, security, and energy management, as well as providing distribution services for heating, ventilation, air conditioning (HVAC), plumbing, and electrical contractors. The company was established in 2018 when it was spun off from Honeywell International, which had been selling residential thermostats and security systems under the Honeywell brand for decades. Resideo inherited the Honeywell Home brand and a large portfolio of connected home devices, including thermostats, security panels, sensors, and water leak detection systems. The company operates through two primary segments: Products & Solutions, which focuses on branded residential devices, and ADI Global Distribution, a leading wholesale distributor of security, AV, and low-voltage products. Resideo serves professional contractors, retailers, and consumers across North America, Europe, and other international markets. Its products are sold under brands such as Honeywell Home, Resideo, and First Alert. The company is headquartered in Scottsdale, Arizona, and is listed on the New York Stock Exchange under the ticker REZI. Resideo positions itself as a provider of trusted, innovative solutions that make homes safer, more comfortable, and more energy-efficient, leveraging its long-standing relationship with the Honeywell brand and its extensive distribution network.
History
Resideo Technologies was formed as a spin-off from Honeywell International in 2018. Honeywell had long been a major player in residential heating and cooling controls, having acquired brands like Honeywell Home and First Alert over the years. In 2018, Honeywell separated its homes product portfolio and ADI distribution business into an independent public company named Resideo Technologies. The spin-off was completed on October 29, 2018, and Resideo began trading on the New York Stock Exchange under the ticker REZI. The company initially faced challenges related to supply chain disruptions and tariffs but has since focused on expanding its connected home offerings and distribution network. Resideo has made acquisitions to bolster its product lines, including the purchase of Buoy Labs (water leak detection) and other smart home technologies. The company continues to operate under the Honeywell Home brand through a licensing agreement with Honeywell, while also developing its own Resideo-branded products. In recent years, Resideo has emphasized energy management and security solutions, aiming to capitalize on the growing smart home market.
