What is being separated
Honeywell Aerospace is a tier-1 aerospace and defense supplier of mission-critical systems and technologies for the production, maintenance and operation of commercial, business-aviation and defense platforms, serving OEMs, airlines, governments and defense primes. Honeywell keeps its automation businesses, having already spun off Solstice Advanced Materials in 2025. Aerospace issued $16.0 billion of senior notes in March 2026 and distributed $15.1 billion of the proceeds to Honeywell before the separation.
Stated rationaleHoneywell said in February 2025 that three focused companies — automation, aerospace and advanced materials — would each carry a simpler strategy and a capital structure suited to its own end markets.

StrongThe write-up
Honeywell's three-way break-up finished on June 29, 2026 when it distributed Honeywell Aerospace to shareholders, one Aerospace share for every two Honeywell shares, eight months after Solstice Advanced Materials went the same way. Aerospace is a tier-1 supplier of mission-critical systems and technologies to commercial, business-aviation and defense platforms, with an installed base on roughly 90% of in-service aircraft and an aftermarket that grows as fleets age. Honeywell keeps building and industrial automation. The parent trades at $134 billion with a Wide moat rating and a quality score of 57 on MoatScope's framework, at 1.06× its fair value estimate; the new company's score and estimate are pending its first stand-alone filings.
