About
Honeywell International is a Fortune 100 diversified technology and manufacturing conglomerate, founded in 1906 as Honeywell Heating Specialty Company and incorporated over decades of mergers—most significantly with AlliedSignal in 1999—now headquartered in Charlotte, North Carolina and trading on Nasdaq (HON). The company generated approximately $36.7 billion in revenues for FY2024 under CEO Vimal Kapur, who assumed leadership in mid-2023 succeeding Darius Adamczyk. In late 2024, activist investor Elliott Management disclosed a $5 billion position in Honeywell and pressed for a strategic portfolio separation, leading to the company's announcement of its most significant restructuring in decades: plans to spin off Honeywell into separate Aerospace and Automation-focused companies, with the Advanced Materials segment spun off first (targeted 2025-2026). This breakup strategy follows the successful conglomerate separations by GE, Emerson, and Johnson Controls into focused pure-play businesses that have commanded higher valuation multiples than diversified conglomerates.
