controls

Johnson Controls International is an Irish-domiciled multinational conglomerate headquartered in Cork, Ireland, that produces fire, HVAC, and security equipment for buildings. As of mid-2019, it employed 105,000 people in around 2,000 locations across six continents. As of 2017, it was listed as 389th in the Fortune Global 500; in 2017, it became ineligible for the Fortune 500, as it was headquartered outside the U.S.The company was formed via the merger of American company Johnson Controls with Tyco International, announced on 25 January 2016. The merger led to the avoidance of taxation on foreign market operations and a financial windfall for the CEO of Johnson Controls at that time, Alex Molinaroli.
