01—Abstract
Summary
Summary of the 8-K filed October 16, 2025. Cited figures are marked; the original filing is the authoritative source.
Honeywell's board has formally approved the spin-off of its Advanced Materials business, which will become an independent public company named Solstice Advanced Materials Inc. (ticker SOLS).
Honeywell will distribute all Solstice shares pro rata at one Solstice share for every four HON shares held at the close of business on the October 17, 2025 record date, with the distribution effective at 12:01 a.m. ET on October 30, 2025. The company states the transaction remains on track, and the filing points to a when-issued trading start for Solstice (SOLSV) around October 20, 2025, followed by a dual-market period for HON shares (regular-way and ex-distribution under HONIV) through October 29.
The filing also discloses that director Rose Lee will resign from Honeywell's board effective immediately prior to the spin-off's consummation, because she will join Solstice's board. Her resignation is described as unrelated to any disagreement with the company's operations, policies, or practices. She remains on the Honeywell board until the spin-off closes.
For investors, the key takeaways are the concrete timeline and mechanics of the separation, which is a major step in Honeywell's portfolio transformation. The filing contains standard forward-looking risk language covering spin-off execution, tax treatment, capital structure and credit ratings, and possible market-price effects. The 8-K itself does not quantify Solstice's financial profile, valuation, or debt allocation, so investors will need to review the Form 10 registration statement and the separation agreement for those details.

Frequently Asked Questions
How many Solstice shares will Honeywell shareholders receive?
Holders of record of Honeywell common stock as of the close of business on October 17, 2025 will receive one share of Solstice common stock for every four shares of Honeywell common stock they hold. Cash will be paid in lieu of any fractional shares.
When will the spin-off take effect and when will Solstice begin trading?
The distribution is effective at 12:01 a.m. New York City time on October 30, 2025. Solstice shares are expected to trade when-issued as SOLSV on or about October 20, 2025, and begin regular-way trading as SOLS on Nasdaq on October 30, 2025.
Will Honeywell's stock trade differently before the distribution?
Yes. From about October 20 through October 29, 2025, HON will trade in two markets. The regular-way market under HON includes the right to receive Solstice shares, while the ex-distribution market under HONIV trades without that right. Investors should check which line they are trading in.
Is the spin-off certain to be completed?
Not necessarily. The distribution is subject to the satisfaction or waiver of conditions in the Separation and Distribution Agreement. The forward-looking statements also flag risks, including the possibility that the spin-off is delayed or not completed, does not achieve its intended benefits, or affects Honeywell's market price, credit ratings, or tax treatment.
Why is director Rose Lee leaving the Honeywell board?
Ms. Lee will resign effective immediately before the spin-off is completed because she will serve on Solstice's board of directors. The company states that her resignation does not involve any disagreement with its operations, policies, or practices, and she will remain on Honeywell's board until the spin-off closes.
