Following Johnson Controls’ divestiture of its residential and light commercial HVAC businesses to Bosch in 2025, nearly all of its revenue comes from commercial HVAC (60%) and fire and security products and services (40%). A 2016 merger joined Johnson Controls’ HVAC and Tyco’s fire and security businesses with the premise that there is synergy in offering a broader variety of automation products and solutions to commercial buildings. We estimate Johnson Controls’ pro forma revenue mix will be one-third products, one-third installation, and one-third services.
