At $60 per share — topping its most recently marketed range of $53 to $55 — Honeywell $HON International's majority-owned quantum computing unit, Quantinuum, pulled in $1.68 billion through its initial public offering, according to CNBC. Thursday's Nasdaq $NDAQ Global Market debut, under the ticker symbol "QNT," follows the sale of 28 million shares in the offering.
The share pricing puts the company's total market value at roughly $15 billion, per The Wall Street Journal. A 30-day overallotment option gives underwriters the right to acquire as many as 4.2 million additional shares should investor demand warrant it. J.P. Morgan and Morgan Stanley $MS served as joint lead active book-running managers.
According to Quantinuum's IPO filing, Honeywell's share of the combined voting power upon deal completion will stand at approximately 48.1%. No pure-play quantum computing company had previously gone public through a conventional IPO process, making this listing a historic first, according to Barron's.
A 2021 merger between Honeywell's quantum computing division and the U.K.-based software firm Cambridge Quantum gave rise to Quantinuum. The Broomfield, Colorado-based company develops full-stack quantum computing platforms, including hardware systems and software tools, for customers in pharmaceuticals, financial services, materials science, and government markets. The company reported $30.9 million in revenue and a net loss of $192.6 million for full-year 2025.
