Johnson Controls International plc is an American, Irish-domiciled multinational conglomerate headquartered in Cork, Ireland,[3] that produces fire, HVAC, and security equipment for buildings.

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.

[21] In July 2024, Johnson Controls said that it will sell a portfolio of its heating and ventilation units to Germany's Bosch Group for $6.7 billion.

[22] In 1982, Johnson Controls enacted what it called a "fetal protection policy", which denied women the right to work on the battery production line because of the potential harm to a fetus they might conceive.

These employees were Mary Craig, who had chosen to be sterilized to avoid losing her job, Elsie Nason, a 50-year-old divorcee, who had suffered a loss of compensation when she was transferred from a high paying job that exposed her to lead, and Donald Penney, who had been denied a request for a leave of absence for the purpose of lowering his blood lead levels because he intended to become a father.

[25] Johnson Controls was one of the defendants in a multimillion-dollar federal court lawsuit in San Juan, Puerto Rico in a case where 98 people perished and 140 were injured in a fire at the DuPont Plaza Hotel and its casino on New Year's Eve, 31 December 1986.

The plaintiffs claimed that Johnson Controls sold and installed an energy management system that failed to give early warning of the fire.

[31] After nine months of trial, the company and its energy management system were absolved of blame when the court issued a directed verdict.

[35] The Power Solutions business unit designs and manufactures automotive batteries for passenger cars, heavy and light duty trucks, utility vehicles, motorcycles, golf carts and boats.

[25][36][37][38][39] It supplies more than one third of the world's lead-acid batteries[40] to automakers and aftermarket retailers including Wal-Mart, Sears, Toyota, and BMW.

[25] This part of the company also manufactures Lithium-ion cells and complete battery systems to power hybrid and electric vehicles such as the Ford Fusion[44] and Daimler's S-Class 400.

Johnson Controls operates HVAC manufacturing plants in the United States in Wichita, Kansas and Norman, Oklahoma.

The Wichita plant primarily produces residential unitary equipment, such as air conditioners, furnaces, and heat pumps for the North American Market under various brands including York and Coleman.

[81] Hillary Clinton condemned the company for wanting to escape United States taxes through the merger after having "begged" the government for financial help in 2008.

[86] Kozlowski testified on his own behalf during the second trial, stating that his pay package was "confusing" and "almost embarrassingly big," but that he never committed a crime as the company's top executive.

[87] Then in May 2007, New Hampshire Federal District Court Judge Paul Barbadoro approved a class action settlement whereby Tyco agreed to pay $2.92 billion (in conjunction with $225 million by Pricewaterhouse Coopers, their auditors) to a class of defrauded shareholders represented by Grant & Eisenhofer P.A., Schiffrin, Barroway, Topaz & Kessler, and Milberg Weiss & Bershad.

According to the SEC, employees of China Marine, a subsidiary of Johnson Controls, employed sham vendors to transfer $4.9M worth of bribes to Chinese government-owned shipyards, to win over businesses and enrich themselves.
