IonQ agreed to acquire Elisity, a software company that stops attackers and ransomware from spreading inside an organization's network, in a deal worth up to $1.3 billion paid entirely in IonQ stock. Elisity's customers include health care companies and hospitals, and its CEO is expected to stay on after the deal closes.

## Key facts

- Up to $150 million of the total is an earn-out tied to Elisity's future performance
- The number of IonQ shares issued will be set using a price between $33.07 and $49.61, so the value moves with IonQ's share price
- Elisity was founded in 2019; the article does not give the closing date or name the approvals needed
- The terms come from a news report citing the Wall Street Journal and a company statement, not from the deal documents
