Quantum computing company IonQ has agreed to acquire cybersecurity firm Elisity in an all-stock transaction valuing Elisity at up to $1.3 billion, according to company executives. The deal includes as much as $150 million in contingent payments tied to Elisity’s future performance.
IonQ Chairman and CEO Niccolo de Masi described the acquisition as a strategic move to address increasing cybersecurity challenges as both quantum computing and artificial intelligence technologies advance. “The bad guys are going to keep taking advantage of new technology,” de Masi said, adding that the coming years will pose heightened cybersecurity risks.
The exact number of IonQ shares to be issued will be calculated based on a price range between $33.07 and $49.61 per share. IonQ’s shares, traded on the Nasdaq, closed down 9% on the day the deal was announced, with the company valued at roughly $16 billion. Since going public via a special-purpose acquisition company in 2021, IonQ’s stock price had experienced significant growth.
IonQ develops trapped-ion quantum computing hardware and software designed to solve complex problems across various industries, including drug discovery and national defense. The technology offers increased accuracy compared to other quantum computing approaches. The company has benefited from support in the United States, with the previous administration under President Trump pushing for advancements in quantum computing and cybersecurity through executive orders aimed at accelerating development and protecting government systems.
Elisity, founded in 2019, provides a cybersecurity platform focused on preventing lateral movement by cyber attackers and ransomware within organizations. Its client base includes healthcare companies and hospitals. James Winebrenner, Elisity’s CEO, is expected to stay on following the completion of the transaction.
De Masi emphasized that the combined companies will work to help clients tackle emerging threats, including those posed by artificial intelligence agents. Recent incidents involving rogue AI hacks, such as coordinated attacks by OpenAI agents on U.S. government websites and concerns about Anthropic’s Mythos model, have heightened awareness within industry and government circles.
Looking ahead, IonQ is preparing for the eventual arrival of “Q-Day,” a projected milestone when quantum computers will have the capability to break current public-key cryptography widely used for securing digital communications. IonQ maintains close collaboration with the U.S. Department of Defense and has pursued acquisitions to broaden its offerings. Earlier this year, the company completed its largest deal to date by acquiring chip maker SkyWater Technology in a transaction valued at $1.8 billion.
