Honeywell Stock Jumps as Breakup Nears

Honeywell shares rose this week after the company used investor presentations to sharpen the case for its planned breakup into two standalone businesses, with the separation expected on June 29.

Barron’s reported that Honeywell stock gained 6.4% on June 11 to $219.12 after the company’s automation business laid out targets for the post-split company. The move followed a June 8 update in which Honeywell reaffirmed full-year guidance and gave investors a clearer view of the coming separation.

What changed this week

The latest presentations gave the market a more concrete picture of what Honeywell will look like after the split. Honeywell said its automation businesses generate about $17 billion in annual sales with operating margins of about 21%.

Over the next three years, that business is targeting annual sales growth of 4% to 6% and margins of about 24%. The company also said the post-split Honeywell Technologies business is guiding to 2026 sales of $19.9 billion to $20.2 billion and adjusted earnings per share of $3.95 to $4.15.

Honeywell Aerospace, the other side of the breakup, is targeting annual sales growth of 6% to 8% and margin expansion. The company’s updated presentation gave investors more detail on how each standalone business is expected to perform after the separation.

The breakup timeline

Honeywell announced in February 2025 that it would separate its automation and aerospace businesses and also spin off Solstice Advanced Materials. The latest step keeps that broader portfolio simplification plan moving toward completion.

The company now expects the aerospace separation to be completed on June 29, 2026. Honeywell Technologies will be the automation-focused company and will keep the HON ticker after the split.

Investors will receive one share of Honeywell Aerospace for every two Honeywell shares they own. Honeywell Aerospace is expected to trade on a when-issued basis under the symbol HONA before the separation closes.

Why investors reacted

The share move reflects a bigger valuation question. Honeywell has said the split should make the two businesses easier to value against peers and help each pursue a more focused operating plan.

That matters because investors may compare Honeywell Technologies more directly with companies such as Emerson and Rockwell Automation, while Honeywell Aerospace will be viewed alongside aerospace peers. The hope is that clearer growth and margin targets could unlock higher multiples for both businesses.

Honeywell’s reaffirmed 2026 guidance also mattered. The company said it still expects full-year sales of $38.8 billion to $39.8 billion and adjusted EPS of $10.35 to $10.65, a sign that management wants to show the breakup is not distracting from execution.

What to watch next

The immediate focus is on whether Honeywell completes the June 29 separation on schedule and how the market treats the new trading setup before and after the split.

Investors are also watching for when-issued trading in HONA, any additional operating detail from either standalone company, and early analyst reactions to the new valuation framework.

The broader question is whether Honeywell can translate the breakup into stronger long-term returns if both businesses hit the growth and margin targets it has now put in front of investors.
