Honeywell
The US industrial group formed when AlliedSignal bought Honeywell Inc. in 1999 and took its name — thermostats and building controls from Minneapolis, aerospace systems and chemicals from New Jersey — which survived a failed sale to General Electric (blocked by the European Commission on 3 Jul 2001), became under David Cote (2002–17) the model of a conglomerate run on one production system, the Honeywell Operating System (HOS), and then, under activist pressure (Elliott's >$5bn stake, Nov 2024) and its own 6 Feb 2025 decision, took itself apart: Solstice Advanced Materials was spun off on 30 Oct 2025 and Honeywell Aerospace (Nasdaq: HONA) on 29 Jun 2026, leaving an automation company that the June 2026 release calls Honeywell Technologies (Nasdaq: HON). Its story turns on an operating system used as a portfolio tool: HOS and a common playbook (pricing, procurement, footprint consolidation) let Honeywell buy businesses and lift their margins, which justified the conglomerate for fifteen years — until investors concluded that the parts were worth more apart than the playbook was worth together.
