IonQ completes $1.15 billion all‑stock acquisition of Zero‑Trust security firm Elisian

IonQ announced the closing of its all‑stock purchase of Elisian, a Zero‑Trust security company, for $1.15 billion in IonQ common stock. The transaction includes an earn‑out that could add up to $150 million if Elisian meets revenue milestones through January 2028. Post‑acquisition, Elisian will remain under its current leadership and continue serving its existing enterprise customers while its technology is integrated with IonQ’s post‑quantum cryptography and quantum key distribution solutions.

IonQ says the deal expands its addressable enterprise and government market by adding Elisian’s 100+ deployments and Zero‑Trust capabilities, creating a single platform that protects against both current cyber threats and future quantum attacks. The additional $150 million earn‑out ties future consideration to Elisian’s performance, potentially diluting existing shareholders if milestones are met.
