That is a useful distinction. Honeywell Aerospace is expected to begin regular-way trading on Nasdaq under HONA on Monday, June 29. S&P Dow Jones Indices says the new company will join the S&P 500 and S&P 100. It will replace Conagra Brands in the S&P 500 and replace Honeywell International in the S&P 100.
The Dow Jones Industrial Average will be handled differently. The Honeywell parent will remain in the Dow under the new name Honeywell Technologies. Honeywell Aerospace will not be added to the DJIA. S&P Dow Jones Indices spelled out the Dow treatment in the same round of index announcements.
That gives the split an unusual shape. HONA begins life with immediate S&P 500 demand and large-cap visibility. HON keeps the familiar ticker, the Dow membership, and the remaining automation business. Of the two, the S&P 500 inclusion is for more meaningful as there are relatively few funds that track the Dow while many many billions of assets track the S&P 500.
Honeywell shareholders of record on June 15 are expected to receive one Honeywell Aerospace share for every two Honeywell shares they owned. The distribution is expected at 12:01 a.m. New York time on June 29. Honeywell Aerospace has been expected to trade when-issued under HONAV, while Honeywell without the Aerospace distribution right has been expected to trade when-issued under HONIV. Honeywell’s June 15 approval announcement says Honeywell Technologies will keep the HON ticker after the separation.
Honeywell also plans a 1-for-2 reverse split of Honeywell Technologies immediately after the spinoff. That should not change the value of the remaining HON business by itself, but it will make per-share comparisons awkward around the distribution.
The more important question is which business gets the better multiple.
Honeywell Aerospace expects about $19.3 billion of 2026 sales and $4.6 billion to $4.7 billion of EBIT. Honeywell Technologies, the automation-focused company that will keep the HON ticker, expects $19.9 billion to $20.2 billion of 2026 sales, adjusted EPS of $3.95 to $4.15, and about $2 billion of free cash flow. Honeywell provided the Technologies outlook when it reaffirmed guidance ahead of the Aerospace separation.
The two companies look similar if the comparison stops at sales. It should not stop at sales.
HONA Starts With The Cleaner Story
Honeywell Aerospace is a large aerospace and defense supplier with engines, avionics, aircraft systems, controls, and aftermarket services. It serves commercial aviation, business aviation, defense, and space customers.
The aftermarket is the heart of the valuation argument. Aircraft stay in service for years. Operators need parts, repairs, upgrades, software, and support long after the original equipment is installed. That installed base is one reason aerospace suppliers can earn better margins and better multiples than ordinary industrial manufacturers.
Honeywell Aerospace expects $4.6 billion to $4.7 billion of EBIT on about $19.3 billion of 2026 sales. That is roughly a 24% EBIT margin.
Reuters reported that Aerospace expects sales to grow 7% to 9% in 2026, with EBIT between $4.6 billion and $4.7 billion, and is targeting $6.5 billion of adjusted earnings by 2030. Reuters also reported that sales are expected to grow 6% to 8% annually through 2030, helped by commercial aviation, aftermarket demand, and defense, and that Aerospace has a $19 billion order backlog, up 20% year over year. Reuters covered the Aerospace investor-day targets here.
Those numbers do not guarantee a premium valuation. They explain why investors will look for one.
The GE Comparison Is The Point
GE Aerospace is the comparison investors will reach for first.
GE gave investors a working example of what can happen when a big industrial conglomerate turns into a focused aerospace company. The old GE breakup left a cleaner aerospace story, and the market rewarded it.
Honeywell is different, but the playbook is familiar enough to matter.
Barron’s leaned into that comparison in its Honeywell piece, quoting The Edge research founder Jim Osman:
“GE was a cleanup. Honeywell is a clarity trade.”
That is the bull case in one sentence. Honeywell is not asking investors to rescue a broken company. It is asking them to put separate prices on two businesses that may have been harder to value together.
“This is not a distressed breakup. It is a valuation breakup.”
That is also why the index treatment matters. HONA will have immediate S&P 500 and S&P 100 visibility. It will not have Dow membership. HON keeps the Dow seat, which matters symbolically, even if the S&P 500 drives far more index-linked assets.
Many spinoffs spend their first few weeks looking for natural holders. HONA begins with forced attention from S&P 500 index funds, aerospace investors, industrial investors, and Honeywell holders deciding which side of the split they want.
HON Keeps The Dow Seat And The Harder Job
Honeywell Technologies will be a large automation company with software, controls, sensing, building systems, process automation, industrial technology, and related businesses.
It is a real business. It is also a harder stock pitch than HONA.
Investors know how to compare Honeywell Aerospace with GE Aerospace and other aerospace suppliers. They can look at margins, aftermarket exposure, backlog, defense demand, supply-chain execution, and free cash flow.
HON has to make a more specific case. It needs to persuade investors that automation, software, controls, and sensing can produce enough growth and cash flow to deserve a strong multiple without Aerospace attached.
Honeywell has already started making that case. At its Honeywell Technologies investor day, management introduced a three-year framework calling for 4% to 6% organic growth, more than 60 basis points of annual margin expansion, over 10% annual earnings growth, and free-cash-flow conversion above 90%. Honeywell’s Technologies investor-day release is here.
Those are good targets. They are also targets for the company investors may be most tempted to sell after the spin.
HON keeps the familiar ticker and the Dow membership. That helps. It does not answer the valuation question by itself. The remaining company still has to prove that automation can carry the old Honeywell name without the higher-margin aerospace business.
Sales Make The Split Look Even. Profits Do Not.
Honeywell Aerospace and Honeywell Technologies are both expected to produce roughly $20 billion of 2026 revenue. That makes the split look balanced at a glance.
The profit picture is more revealing.
Aerospace expects $4.6 billion to $4.7 billion of EBIT on about $19.3 billion of sales. Honeywell Technologies expects about $2 billion of free cash flow on $19.9 billion to $20.2 billion of sales.
Those are different businesses. Aerospace has higher margins, a large installed base, aftermarket revenue, defense exposure, and a peer group investors understand. Technologies has scale, cash flow, and an automation plan that still needs to earn the market’s confidence.
That does not mean HONA is automatically the better investment. It means the old Honeywell multiple may not have been giving Aerospace full credit.
The Index Split Changes The First Week
Spinoffs often get sloppy early trading. Some holders sell because the new company is too small. Some sell because it does not fit a mandate. Some funds cannot own it. Some investors simply do not want to do the work.
HONA should have a different first week.
S&P Dow Jones Indices is adding Honeywell Aerospace to the S&P 500 and S&P 100. That creates S&P index-related demand right as regular-way trading begins. It also puts HONA immediately in front of large-cap managers who might otherwise wait a quarter or two before doing the work.
The Dow treatment cuts the other way. Honeywell Technologies keeps the Dow seat, and HONA does not join. In a price-weighted index like the Dow, that also avoids putting two Honeywell pieces into the 30-stock average right after the separation.
There can still be pressure. Honeywell holders who prefer automation may sell HONA. Aerospace-focused buyers may sell HON. Index flows can distort early prices. The reverse split can make brokerage statements look strange. None of that changes the core issue.
The market is about to put two separate prices on what used to be one Honeywell.
What To Watch On June 29
The first number to watch is HONA’s implied value against 2026 EBIT of $4.6 billion to $4.7 billion.
If HONA trades at a premium aerospace multiple, the market is saying Honeywell’s aerospace business deserved a cleaner public valuation. If HONA trades more like a supplier with a good story but execution risk, then HON’s valuation will matter more to the combined return.
The second number is the remaining HON value. Honeywell Technologies needs to show that automation can stand on its own, grow organically, improve margins, and convert earnings into cash.
The third question is who owns the stocks after the first few days. If HONA quickly finds aerospace and S&P index buyers while HON holds industrial and automation investors, the split will look like a clean valuation event. If one side is treated as the unwanted stub, the early trading will say so.
Barron’s framed the optimistic case as two ways to win: Aerospace gets valued properly and the remaining automation company gets a cleaner multiple. That is plausible. It is also not automatic.
HONA starts with the better story. HON starts with the Dow seat and more to prove.
By this time next week, investors should have a much clearer idea of how much Aerospace was worth inside Honeywell all along.
