Honeywell’s Quantinuum targets $14.3 billion valuation in upsized US IPO
The Broomfield-based company, formed from Honeywell’s quantum division and Cambridge Quantum, is set to list on the Nasdaq under the symbol QNT.
Honeywell’s quantum computing subsidiary, Quantinuum, has revised upwards the terms of its initial public offering on the US market, targeting a valuation of up to $14.3 billion. The Broomfield, Colorado-based company is now seeking to raise $1.46 billion through the marketing of 26.5 million shares priced between $53 and $55 each. This represents a significant increase from its earlier aim to raise $1.05 billion by offering approximately 21.1 million shares in the $45 to $50 range.
The adjustment underscores robust institutional demand and investor appetite for quantum computing technology. Quantinuum, established in 2021 through the combination of Honeywell’s quantum division and Cambridge Quantum, is expected to list on the Nasdaq under the symbol QNT on Thursday. J.P. Morgan and Morgan Stanley are acting as joint lead active book-running managers for the offering.
Quantum computing has attracted growing interest due to its potential to accelerate complex tasks in drug discovery, financial modelling, and cryptography, solving problems faster than classical computers. However, the sector faces major technical challenges, including high error rates that currently limit practical performance. Despite these hurdles, recent bookings have accelerated, indicating growing commercial traction for the technology.
Quantinuum is differentiated from many peers that have gone public via Special Purpose Acquisition Companies by its operating history from Honeywell, substantial research and development investment, and a workforce of around 700 employees. While the company is in the early stages of commercial growth, the upsize suggests that investors view Quantinuum as a scarce strategic asset.
Upon completion of the offering, Honeywell will retain approximately 48.1 per cent of the combined voting power in the company. Additionally, Quantinuum will receive $100 million in funding as part of a broader US government initiative to take equity stakes in nine quantum-computing firms, a move that follows a recent $2 billion announcement by the US government to support the sector.
