• Stakk secures largest individual client contract worth A$7.85M (US$5.5M)
• Contract reflects growing enterprise adoption of Stakk's AI-native execution-layer infrastructure
• Deployment to drive continued expansion across U.S. regulated sectors

Stakk Limited (ASX: SKK), a leading AI-native trust and decisioning infrastructure provider for regulated industries, has announced that its wholly owned U.S. subsidiary, Stakk IQ, Inc., has secured a major new enterprise client in the United States worth A$7.85 million (US$5.5 million) in revenue over a 12-month period. This agreement represents the largest individual client contract secured by the Company and reflects growing enterprise adoption of Stakk's AI-native execution-layer infrastructure in highly regulated environments, where identity certainty, fraud mitigation, and auditability are critical. By combining federated signal intelligence, real-time interaction validation, and deterministic decisioning, Stakk operates within the execution path of digital interactions, governing whether transactions are permitted to proceed in compliant, auditable environments. The Company expects this deployment to drive continued expansion across U.S. regulated sectors, building on its established leadership position in financial services and recent expansion into telecommunications, and now extending into healthcare and other regulated industries, as demand for integrated, real-time trust infrastructure accelerates.
