Quantinuum has filed to go public in the United States with an indicative valuation of up to $12.7 billion, the company disclosed on Tuesday. The offering is structured around the sale of approximately 21.05 million shares priced between $45 and $50 per share, which would allow Quantinuum to raise up to $1.05 billion if the full range is taken up.
The business, headquartered in Broomfield, Colorado, last secured private funding at a $10 billion valuation. That prior round established a baseline that the IPO would exceed should the company achieve the upper end of its current price range.
Quantinuum was created in 2021 through a separation from Honeywell combined with a merger involving Cambridge Quantum. The company's board chair is Honeywell's chief executive, Vimal Kapur, while day-to-day leadership is headed by Rajeeb Hazra, who previously served at Intel. The planned public listing will appear on the Nasdaq exchange under the ticker symbol "QNT."
Financial institutions J.P. Morgan and Morgan Stanley have been named as joint lead active book-running managers for the transaction. The filing and market approach come at a time when new public listings are attracting investor interest, particularly in areas deemed strategically important. The sectors specifically cited as drawing renewed backing include AI infrastructure, defense and other critical technologies. The company and its advisers are seeking to tap that investor appetite amid continuing geopolitical uncertainty that market participants say has not dampened interest in these categories.
The IPO proposal would convert private backing into public equity while positioning Quantinuum to access broader capital markets. The filing materials indicate the company's intention to list publicly rather than provide detail on how the proceeds will be allocated. Quantinuum's leadership and the choice of underwriters suggest the offering is being structured to reach institutional investors comfortable with high-technology and strategic-technology plays.
Summary
Quantinuum plans a U.S. IPO that could value the firm at up to $12.7 billion by selling about 21.05 million shares at $45 to $50 apiece, aiming to raise up to $1.05 billion. The company, formed after Honeywell separated and merged with Cambridge Quantum in 2021, will list on Nasdaq as QNT with J.P. Morgan and Morgan Stanley as joint book-runners.
