Quantinuum, the quantum-computing company majority-owned by Honeywell International, is now in line for a potential initial market capitalization topping $14 billion after boosting the size and price range of its planned initial public offering.

Quantinuum on Monday said it plans to sell 26.5 million shares at between $53 and $55 apiece in the IPO, up from prior plans to offer nearly 21.1 million shares at between $45 and $50 each.

At the $54 midpoint of the new range, the Broomfield, Colo., company said it expects net proceeds of nearly $1.36 billion, or around $1.56 billion if the underwriters exercise an option to buy an additional 3.98 million shares.

Quantinuum, which had previously expected to raise up to $1.09 billion, said it would have about 257.1 million shares outstanding after the IPO, assuming an exercise of the overallotment option, for a market capitalization of nearly $14.5 billion at the $55-a-share pricing high end.
