Quantinuum, the quantum-computing company majority-owned by Honeywell International, is going public.
Quantinuum confidentially submitted a draft registration statement with the Securities and Exchange Commission on Feb. 17 for a proposed initial public offering, Honeywell said Wednesday.
The number of shares and price range for the proposed offering have yet to be determined, it said.
Quantinuum was formed in 2021 through the merger of Cambridge Quantum Computing and Honeywell Quantum Solutions, which was spun out of the larger conglomerate Honeywell. Last year, it announced a $600 million equity capital fundraise at a premoney valuation of $10 billion, making it one of the most valuable private quantum companies.
Quantinuum's planned IPO comes as Honeywell is in the process of carving itself into three publicly traded companies.
The Charlotte, N.C., industrial conglomerate in October completed the spinoff of its advanced-materials business as Solstice Advanced Materials. The company is planning to spin off its aerospace business, expected to be completed in the third quarter of 2026.
Honeywell earlier this week agreed to sell its productivity solutions-and-services business to Brady for $1.4 billion, part of its ongoing efforts to simplify operations.
