IonQ agrees to buy zero-trust security firm Elisity for up to $1.3 billion
The deal links network access controls with IonQ’s post-quantum security products, but Elisity’s financial results were not disclosed and the transaction still needs regulatory approval.
Executive summary
- Deal terms: IonQ said it signed a definitive agreement to acquire privately held Elisity in an all-stock transaction valued at up to $1.3 billion. The maximum includes up to $150 million in performance-based earnout consideration; the announcement does not mean that all of the maximum value will be paid.[1][2]
- What changes hands: Elisity sells software for zero-trust network security, including microsegmentation and identity-based access policies. IonQ says the combination would pair that platform with its post-quantum cryptography and quantum key distribution products. Those are the companies’ stated plans, not evidence that integrated products are already available.[1][3][2]
- What remains uncertain: The companies expect the transaction to close in the fourth quarter of 2026, subject to customary closing conditions and regulatory approval. IonQ’s announcement did not disclose Elisity revenue or provide a closing guarantee.[1][4]
IonQ, a publicly traded quantum-computing company, announced a definitive agreement on Oct. 12 to acquire privately held cybersecurity firm Elisity in an all-stock transaction valued at up to $1.3 billion. The stated maximum includes as much as $150 million in earnout payments tied to Elisity’s performance, so the headline amount is not a guaranteed purchase price.[1][2]
Elisity’s software applies zero-trust access policies to users, devices and workloads on enterprise networks, with a focus on microsegmentation. IonQ says it intends to connect that platform with its post-quantum cryptography and quantum key distribution offerings. Elisity chief executive James Winebrenner described the proposed combination as a way to extend the company’s existing identity and policy platform; neither announcement establishes that a combined product is ready or has been adopted by customers.[1][3][2]
The proposed purchase would expand IonQ beyond quantum hardware and software into a conventional enterprise-security business. IonQ has framed the move as a way to bring security products together for government and corporate customers. That cross-selling rationale is the company’s stated strategy; the public announcement does not quantify expected revenue, cost savings or customer commitments from integration.[1][2][4]
IonQ said the number of its shares issued at closing will be calculated using a 20-trading-day volume-weighted average price, subject to a floor of $33.07 and a ceiling of $49.61 per share. The terms make the share calculation sensitive to IonQ’s price within that range, while the earnout depends on future performance. IonQ did not publish Elisity’s revenue in the announcement, a gap noted by investor coverage from The Motley Fool.[1][4]
The companies expect to close the acquisition in the fourth quarter of 2026, pending customary conditions that include regulatory approval. Until it closes, Elisity remains a separate company and IonQ’s announced product plans remain prospective.[1][2]
