IonQ to Acquire Elisity for $1.3 Billion

IonQ, a quantum computing company, has agreed to acquire Elisity, a cybersecurity company focused on Zero Trust, in an all-stock deal valued at up to $1.3 billion. The agreement includes up to $150 million in additional payments tied to Elisity’s business performance.

The acquisition will combine IonQ’s post-quantum cryptography (PQC) and quantum key distribution (QKD) technologies with Elisity’s security platform. Elisity helps companies control network access by identifying users, devices, software, and AI agents, then limiting their connections to what they need. This approach is designed to reduce the spread of cyberattacks and prevent unauthorized access.

IonQ plans to combine the two companies’ technologies to protect business and government networks against current cyberattacks and future quantum computing threats. The companies also expect to cross-sell their products and develop integrated security solutions.

The deal is expected to close in the fourth quarter of 2026, subject to regulatory approval and other customary conditions. The number of IonQ shares issued will depend on its stock price before closing, within an agreed range of $33.07 to $49.61 per share.
