What Happens to My Shares When a Company Spins Off a Division?
Direct answer
Spin-off steps for shareholders
You keep your parent-company shares and, if you hold them on the record date, you automatically receive shares of the new company in proportion to what you own. The parent's share price drops by roughly the value of the business that left, so your total value starts out about the same. Most large US spin-offs are designed to be tax-free under Section 355 of the tax code, apart from cash paid for fractional shares, and your original cost basis is split between the two holdings using the allocation the company publishes on IRS Form 8937. In Honeywell's June 2026 spin-off, holders received one Honeywell Aerospace share for every two Honeywell shares.
- Record date decides who receives the new shares
- New shares arrive automatically in your brokerage account
- Parent price falls by about the value of the spun-off unit
- Often tax-free under Section 355, except cash for fractional shares
- Basis is split using the company's Form 8937 allocation
One morning your brokerage account shows a stock you never bought. Nothing went wrong: the company you own split itself in two, and you now own a piece of both.
What people on X are asking
In June 2026 a market data account summarised Honeywell's aerospace spin-off with an immediate reverse split: one HONA share for every two HON shares held on the June 15 record date, with when-issued trading starting first. In April 2026 a special-situations account flagged a filing for FedEx's planned spin-off of its FedEx Freight business as a separate public company. And a June 2026 thread reported a media company's stock jumping on spin-off plans, which we did not verify. We checked the Honeywell details against the company's own release.
The fact-checked answer
The basic mechanics. In a spin-off the parent distributes shares of a subsidiary to its own shareholders, pro rata. You do not pay anything and you do not have to act. The key dates are:
- Record date: you must be a holder of record to receive the new shares.
- When-issued period: the new company may trade on a "when-issued" basis before the distribution, and the parent can trade both with and without the right to receive the new shares.
- Distribution date: the new shares are credited, and "regular-way" trading in them begins.
A 2026 worked example. Honeywell announced a record date of June 15, 2026 and an expected distribution on June 29, 2026, with holders receiving one share of Honeywell Aerospace for every two Honeywell shares. Honeywell Aerospace was expected to trade when-issued on Nasdaq as HONAV from about June 15 and regular-way as HONA from June 29. Honeywell also announced a 1-for-2 reverse split of its own stock on June 29. The company said the spin-off was expected to be tax-free for US federal income tax purposes, except for cash received instead of fractional shares, and that fractional shares from the reverse split would be sold and paid out in cash.
UXS decision diagram
What happens to 100 Honeywell shares in that deal?
Text version of the diagram
- Did you hold the shares on the June 15, 2026 record date? If no: No HONA shares; buyers after the record date paid a price that included them, or bought ex-distribution
- Does your holding divide evenly by two? If no: You receive whole shares plus cash for the fraction, which is taxable
- Are the shares in a taxable account? If no: No tax event in an IRA or similar account
- Otherwise: You end up with 50 HONA shares and, after the 1-for-2 reverse split, 50 Honeywell shares, and you split your original basis between them

What happens to the price. On the distribution date the parent's price falls by roughly the value of the business that has gone. A $100 stock might open near $70 while the new company's shares are worth about $30 per parent share. Your total value is about the same at the start; afterwards the two stocks move independently.
Tax: why most spin-offs are tax-free. Section 355 of the Internal Revenue Code lets a corporation distribute stock of a controlled subsidiary to shareholders without the shareholders recognising gain or loss, if strict conditions are met, including active businesses on both sides and a genuine business purpose. Companies usually get a tax opinion or IRS ruling first and say so in their filings. A spin-off that fails those tests can be taxed as a dividend, so read the company's statement.
Tax: splitting your cost basis. Your total basis does not change, but it must be divided between the parent and the new shares. The issuer reports the allocation, typically based on relative trading prices after the spin, on IRS Form 8937, the report of organisational actions affecting the basis of securities. If you paid $20,000 for 100 parent shares and the company says 70% of value stayed with the parent, your parent shares carry $14,000 of basis and the new shares $6,000. Brokers usually adjust this, but check it; IRS Publication 550 explains basis rules for stock distributions.
Quick poll
After a spin-off, what do you do with the new shares?
What each answer means
- Keep both: Often sensible; you now own two focused businesses.
- Sell the spun-off shares at once: Common, and one reason new spin-offs can be weak at first: index funds and holders who never wanted them sell.
- Sell the parent and keep the new company: Possible, but decide on fundamentals, not the event.
- Not sure: Read both companies' filings; the Form 10 describes the new business.

Do spin-offs perform well? Some academic studies have found positive long-run returns for spun-off firms and parents, others find weaker results in recent decades. Early selling pressure is common because some holders cannot or do not want to hold the new stock. Treat the event as neutral for value and judge each business separately; compare with what happens when a stock splits and reverse stock splits.
