IonQ to acquire cybersecurity firm Elisity in an all‑stock deal worth up to $1.3 billion

IonQ announced an agreement to buy Elisity, a Zero‑Trust security company, in an all‑stock transaction valued at up to $1.3 billion, with an additional earn‑out of up to $150 million tied to Elisity’s future performance. The exchange ratio will be set using IonQ’s share price that falls within a reference range of $33.07 to $49.61 per share. The deal is expected to close in the fourth quarter of 2026, subject to customary closing conditions and regulatory approval.

The acquisition expands IonQ’s quantum‑security portfolio by adding Elisity’s enterprise Zero‑Trust platform and gives shareholders new shares based on the stated price range, which could dilute existing holdings. Completion of the transaction will also allow cross‑selling of quantum‑safe solutions to Elisity’s 100‑plus customers, potentially accelerating revenue growth for IonQ.
