IonQ says it has agreed to buy cybersecurity company Elisity in an all-stock transaction valued at up to $1.3 billion. The deal is structured to include up to $150 million in earnouts based on Elisity’s future performance, according to reporting.

IonQ frames the acquisition as a way to expand its cybersecurity offering. Bloomberg says the move is intended to bolster a platform designed to address AI-assisted threats and also prepare for emerging quantum risks. Other coverage similarly highlights the overall consideration and the earnout component, without detailing additional terms.

The sources align on the target company, the deal size range, and the all-stock nature of the agreement, while emphasizing different motivations—most notably, broader cybersecurity platform expansion and specific threat categories such as AI-enabled dangers and quantum-era security challenges.
