HON vs APO Comparison

Honeywell traces its roots to 1885 with Albert Butz's firm, Butz Thermo-Electric Regulator, which produced a predecessor to the modern thermostat. Other inventions by Honeywell include biodegradable detergent and autopilot. Today, Honeywell is a global multi-industry behemoth with one of the largest installed bases of equipment. It operates through four business segments: aerospace technologies, industrial automation, energy and sustainability solutions, and building automation. Recently, Honeywell has made several portfolio changes to focus on fewer end markets and align with a set of secular growth trends. The firm is working diligently to expand its installed base, deriving around one third of its revenue from recurring aftermarket services.

Apollo is one of the world's largest alternative asset managers, with $1.047 trillion in total assets under management, or AUM, including $858.0 billion in fee-earning assets, at the end of June 2026. The company has two core operating segments: asset management and retirement services. Apollo operates with scale in most of its major asset management endeavors—private equity (with an estimated $137.2 billion in total AUM and $76.3 billion in fee-earning AUM), real estate/real assets ($60.8 billion/$27.6 billion), and credit ($849.3 billion/$754.1 billion). Apollo has a distribution profile that is likely not too far off from the industry averages—with 84% of its assets held by institutional investors and 16% by high-net-worth clients.
