What Advanced Materials Spin-Off Means for Honeywell

Honeywell has completed the spin-off of its Advanced Materials business, which now operates as Solstice Advanced Materials, an independent, publicly-traded company.

The move forms part of the manufacturing giant's plan to reshape itself into three standalone entities, each with clear priorities in aerospace, automation and materials innovation.

Vimal Kapur, Chairman and CEO, comments: "The completion of this spin-off marks a major advancement in Honeywell’s transformation to become three independent, industry-leading companies with distinct strategies and growth drivers.

"It reflects disciplined execution, and reinforces our belief that a more focused portfolio will position Honeywell to deliver greater long-term value for shareowners and seize new opportunities to address modern challenges for our customers.”

Honeywell's strategy

The process began in October 2024, when Honeywell outlined its intention to spin off the Advanced Materials unit.

By February 2025, following a one-year portfolio review led by Vimal Kapur, Honeywell had announced plans to separate the Automation and Aerospace businesses as well. The full transformation now unfolds with the spin off of Solstice.

Each business under the Honeywell umbrella now pursues its own path with independent strategies, customer focus and investment plans.

Vimal adds: “This transition is a key step in Honeywell’s transformation into three independent, industry-leading companies, each with distinct strategies, growth drivers and customer focus. It reflects our disciplined execution and reinforces our belief that a more focused portfolio will unlock greater long-term value for shareowners and better position us to meet the evolving needs of our customers.”

Honeywell describes Honeywell Automation as a company focused on solving complex global problems and powering digital transformation. It generated US$18bn in annual revenue in 2024.

Honeywell Aerospace, which reported US$15bn in annual revenue, is described by the organisation as a "premier technology and systems provider" for all aircraft types.

Solstice begins trading

The spin-off of Solstice Advanced Materials was completed on 30 October, with the distribution of all issued and outstanding shares of Solstice common stock to Honeywell shareholders.

Each investor received one share of Solstice stock for every four shares of Honeywell common stock held as of the close of business on 17 October.

Sharing the news of Solstice's spin-off, Vimal added: “Their passion, innovation and dedication have played a vital role in Honeywell’s success and their legacy will always be a part of our story. Congratulations to David Sewell and the Solstice team, we look forward to watching all that you achieve in this exciting new chapter.”

Solstice now operates with its own leadership under David, with a focus on materials technologies such as refrigerants and thermal management systems.

The name Solstice comes from Honeywell’s portfolio of low-global-warming-potential refrigerants and foaming agents, which now form the basis of the independent company’s offering.

Delivering shareholder value

Honeywell highlights five key benefits for stakeholders following the shift to three independent companies.

• Simplified strategy focus
• Greater financial flexibility for distinct organic growth opportunities throughout investment cycles
• Improved ability to tailor capital allocation priorities in alignment with strategic focus 
• Focused Board of Directors and management teams for each sector with deep expertise
• Distinct investment profiles that position each company, unlocking greater long-term value

The company realignment positions each new entity to better adapt to changing customer needs and market environments. The structure aims to deliver long-term shareholder value, reduce portfolio complexity and improve execution across each core sector.

Honeywell’s transformation strategy continues with this spin-off, with all three new businesses now operating independently. Solstice Advanced Materials launches with its foundation in sustainable material technologies, while Automation and Aerospace proceed toward their standalone futures with sector-specific growth plans.

Each company now moves forward with dedicated leadership, clearer priorities and capital structures designed to support organic growth and operational efficiency across economic cycles.
