Honeywell makes equipment, software and services for aircraft, factories, buildings and energy plants. It sells them around the world to aircraft makers, airlines, the U.S. government, plant operators, building owners, and refining and chemical companies. Its products range from aircraft engines, avionics (flight electronics) and wheels and brakes to factory control systems, sensors, fire and security systems, and licensed technology and catalysts for refineries.
In 2025 Honeywell's sales grew 8% to $37.4 billion. It reported four segments. Aerospace Technologies had revenue of $17,510 million, Industrial Automation $9,401 million, Building Automation $7,367 million, and Energy and Sustainability Solutions $3,134 million. The competitors it names include RTX, Safran and Thales in aerospace; Johnson Controls, Schneider Electric and Siemens in buildings; and Emerson Electric and Rockwell Automation in industrial automation.
At the end of 2025 Honeywell employed about 101,000 people in 79 countries, about 36,000 of them in the United States. In October 2025 it spun off its Advanced Materials business as a separate public company, Solstice Advanced Materials, and in June 2025 it spent $2.2 billion to buy Sundyne. It plans to split into two public companies, Honeywell and Honeywell Aerospace, and expects to finish the separation in the third quarter of 2026.
