About
Johnson Controls International plc is a Cork, Ireland-incorporated building technology company — publicly traded on the New York Stock Exchange (NYSE: JCI) as an S&P 500 Industrials component — providing smart building systems, HVAC equipment, fire detection and suppression, security systems, and building management automation software through approximately 100,000 employees serving commercial, industrial, and institutional buildings in 150 countries. Johnson Controls appointed Joakim Weidemanis as President and CEO effective March 12, 2025, succeeding George R. Oliver who retired after eight years leading the company's transformation from a diversified industrial conglomerate (including auto interiors, automotive batteries, and York HVAC) into a pure-play commercial building technology company. Weidemanis brings 13 years of Danaher experience — most recently as Executive Vice President of Diagnostics and China — applying Danaher Business System operational excellence disciplines to Johnson Controls' building technology platform. A defining 2024 strategic action was the $8.1 billion sale of Johnson Controls' Residential and Light Commercial HVAC business (including the York residential, Coleman, and Champion brands) to Bosch — focusing Johnson Controls entirely on commercial, industrial, and institutional building automation, HVAC, fire, and security. In fiscal year 2024 (ending September 2024), Johnson Controls reported revenue of approximately $22 billion (pre-divestiture), with the commercial and industrial building services generating approximately $12-13 billion in pro-forma revenue after the residential HVAC divestiture.
Melbourne FL defense electronics (NYSE: LHX) $21.3B FY2024 revenue (+8%); tactical radios, ISR, electronic warfare, JADC2 networks, Falcon radio family competing with Raytheon and Northrop Grumman.
About
L3Harris Technologies, Inc. is a Melbourne, Florida-based defense electronics and technology company — publicly traded on the New York Stock Exchange (NYSE: LHX) as an S&P 500 Industrials component — providing advanced defense electronics, intelligence, surveillance and reconnaissance (ISR) systems, communication systems, and aviation products for US and allied defense forces through approximately 47,000 employees across four segments: Integrated Mission Systems (ISR aircraft modifications, electro-optical/infrared systems, maritime patrol aircraft), Space & Airborne Systems (military satellite communications, electronic warfare, precision weapons guidance), Communication Systems (tactical radio communications, night vision devices, public safety communications), and Aerojet Rocketdyne (integrated into L3Harris via investment, pending completion). L3Harris Technologies was formed in June 2019 through the merger of L3 Technologies and Harris Corporation — combining Harris's radio communication and space systems expertise with L3's ISR sensors, aircraft modification, and training systems capabilities to create the sixth-largest US defense contractor by revenue. In fiscal year 2024, L3Harris reported revenues of $21.3 billion (+8% year-over-year), with strong growth driven by JADC2 (Joint All-Domain Command and Control) radio and network programs, F-35 avionics subsystems production, and international NATO ally military communication equipment demand. CEO Christopher Kubasik has focused on margin improvement and portfolio optimization — divesting non-core businesses (commercial aviation training — sold Pilot Training business, Link Simulation & Training to CAE) while investing R&D in the electronic warfare (EW) and space domain awareness capabilities where L3Harris holds differentiated technology advantages.
