Quantinuum raised $1.68 billion on June 4 by selling 28 million Class A shares at $60 each on Nasdaq under the ticker QNT, and shares promptly opened at $68, a 13% premium over the offering price.

That first-day performance valued the company at roughly $15.7 billion.

What Quantinuum actually does

The company was born in 2021 from the merger of Honeywell’s quantum division and Cambridge Quantum. The result is a company focused on trapped-ion quantum systems, specifically its H2 series hardware.

CEO Rajeeb Hazra oversees roughly 2,500 employees working across enterprise applications, scientific computation, and security technologies.
