Honeywell is still undervalued with its spinoffs coming, including the upcoming aerospace separation. x.com 

Honeywell looks like GE 2.0, worth about $265 billion in parts against a $135 billion market cap, with its aerospace spinoff coming in June. The core business is worth about $156 billion at 6.5x its $24 billion of revenue, aerospace about $98 billion at 7x $14 billion, and its 55% Quantinuum stake about $11 billion if Quantinuum is worth around $20 billion. x.com  x.com  x.com 

Honeywell Aerospace starts life with heavy spin-off burdens, so it is worth waiting for a better price. It carries $15.85 billion of debt and $800 million of annual interest after sending $15.1 billion to Honeywell, pays $1.125 billion over five years to use the Honeywell name, faces standalone overhead and took on the $375 million Flexjet settlement. After a guidance cut, institutions may shun it through year-end and underwater holders may sell for tax losses. It should still do well long term. … Show more

Honeywell Aerospace has always been a weak business, with a worse mix than better aerospace names such as HEI, TransDigm, Howmet and GE. With so many good aerospace businesses available, there is little reason to own it. @pitandhummus agrees that, underwritten standalone after the spin-off, it looked overstated relative to much better businesses like GE. x.com  x.com 

GE Aerospace's premium valuation looks hard to justify as margin expansion slips to 2028. Services are guided to low-double-digit growth with flat margins in 2027, while faster-growing original equipment could keep overall margins flat. Roughly 10-12% revenue growth would imply about $1.2-1.3B operating profit growth, down from about $1.9B in 2026, against a 35-38x multiple. Q3 departures rose only 1%, with prolonged Brent above $100 a further near-term risk. x.com 

Parker-Hannifin is the better aerospace holding than Honeywell Aerospace: time-tested Parker kept delivering while the newly spun-off Honeywell Aerospace reported a disastrous quarter. Honeywell Aerospace is not a GE-style spin-off, and the weakness is company-specific: most aerospace stocks are working, with GE among the S&P 500's top five performers and Honeywell Aerospace in the bottom five. As a new name in tax-loss season, it likely stays under pressure even if it bounces to the $170s. … Show more

GE Aerospace earns most of its money servicing a huge installed engine base, and record air traffic keeps that base turning. Engines sell at up to 70% off, while shop visits bring up to 70% of lifetime revenue; services were about 70% of 2025's $42B revenue, with a $210B backlog. At 43x earnings versus a 37x five-year average it is not cheap, a premium backed by the end of the conglomerate discount, margins and visibility. A correction would come only with a normal general market pullback. x.com  … Show more
