Honeywell has been a conglomerate for over a century, bundling aerospace engines, building thermostats, and specialty chemicals under one corporate roof. On March 3, 2026, it filed the paperwork to end that era, registering its $17.4 billion aerospace division as an independent company that will trade on Nasdaq under the ticker HONA. The filing is the second of three planned separations that will split Honeywell into entirely distinct publicly traded companies by late 2026.

The filing is the second of three planned separations that will split Honeywell into entirely distinct publicly traded companies by late 2026.
The breakup, driven by pressure from activist investor Elliott Investment Management and its $5 billion-plus stake, follows the playbook that transformed General Electric from a sprawling conglomerate into three focused companies whose combined market value roughly quadrupled. For Honeywell shareholders, the question is whether shedding the so-called conglomerate discount—the tendency for diversified companies to be valued at less than the sum of their parts—will unlock the 50-to-75 percent upside Elliott projected when it launched its campaign in late 2024.
