IonQ, Inc. (IONQ) has entered into a definitive agreement to acquire Zero Trust cybersecurity provider Elisity, Inc. in an all-stock transaction valued at up to $1.3 billion. The deal structure includes an earnout component of up to $150 million tied to the future performance of Elisity. The exact number of shares issued will depend on IonQ's volume-weighted average stock price over the 20 trading days prior to closing, with a price cap set at $49.61 per share and a floor at $33.07 per share.

The acquisition combines IonQ's post-quantum cryptography and quantum key distribution technology with Elisity's enterprise Zero Trust network controls. Elisity brings over 100 global customer deployments, double-digit growth in its customer base, and zero customer churn. The acquisition grants IonQ immediate entry into the microsegmentation security market, an industry estimated to be worth over $10 billion, while opening cross-selling channels across government and enterprise networks.

Investors will monitor the closing of the transaction and the integration of Elisity's executive team and client base into IonQ's sales pipeline. Key elements to watch include combined customer adoption rates, progress toward the $150 million earnout target, and overall revenue momentum following a 40% year-over-year rise in IonQ's multiproduct revenue in the second quarter of 2026.
