Announcement PDF ASX Release 25 May 2026 Decidr Partners with SCXai for Sovereign Inference in Australia Decidr AI Industries Ltd (ASX: DAI) (“Decidr” or the “Company”) is pleased to announce a strategic commercial partnership with SouthernCrossAI (“SCX.ai” or “SouthernCrossAI”), an Australian sovereign AI cloud provider. The partnership names SCX.ai as Decidr’s first sovereign inference partner in Australia and supports the Company’s Knowledge Security roadmap and the rollout of DecidrOS to Australian enterprise customers. Highlights • Commercial partnership signed with SCX.ai, an Australian sovereign AI cloud provider. • First Australian node in Decidr’s multi-jurisdiction sovereign inference architecture, alongside Decidr’s broader multi-model strategy across Europe, Asia-Pacific and the United States. • Supports Decidr’s Knowledge Security offering by giving Australian enterprise and any government customers a compute layer where tacit organisational knowledge can be captured, fine-tuned and continually updated on infrastructure within Australian jurisdiction. • Aligned with Australia’s sovereign AI agenda, including the National AI Plan 2025 released by the Department of Industry, Science and Resources in December 2025 and sector-specific data-residency requirements across financial services, healthcare and government. • Production-grade sovereign capacity for agentic AI workloads running on DecidrOS, with a scheduled SCX.ai deployment plan that includes additional Australian and Asia-Pacific nodes. About SCXai SCX.ai (SouthernCrossAI) is an Australian sovereign AI cloud provider founded and led by David Keane (Founder and Chief Executive Officer). SCX.ai delivers onshore AI inferencing infrastructure designed to keep models, data and system logs within Australian jurisdiction, serving regulated sectors including financial services, healthcare and government. In October 2025, SCX.ai announced a partnership with SambaNova to launch what it describes as Australia’s first sovereign AI cloud, and in January 2026 brought its initial sovereign inferencing node live at Equinix’s SY5 data centre in Sydney. SCX.ai has a publicly stated rollout plan that includes a further 10 nodes across Australia and the Asia-Pacific region Strategic Context - Why Sovereignty Now The question enterprise buyers are now asking is no longer whether AI can do the task, it is who owns the infrastructure the task runs on. The United States CLOUD Act allows U.S. law enforcement to compel data from U.S.-controlled providers regardless of where that data is physically stored. Australia’s National AI Plan 2025, together with sector-specific data- residency obligations across financial services, healthcare and government, has moved jurisdictional control from a procurement preference to a procurement requirement. Decidr’s response is a multi-jurisdiction sovereign inference architecture: a curated set of base-model and infrastructure partners selected on the basis of jurisdiction, performance and the ability to operate inside the customer’s control plane. SCX.ai is the Australian node in that architecture. Supporting the Knowledge Security Roadmap Decidr is building infrastructure that captures how organisations actually reason, fine-tunes a sovereign model on that captured decision structure, and runs the resulting model on infrastructure the enterprise controls. This is the foundation of the Company’s Knowledge Security offering, currently being commercialised through Decidr’s Sugarwork business and its professional services channel partners. The SCX.ai partnership delivers the compute layer that makes this possible inside Australia. Enterprise customers running DecidrOS on SCX.ai infrastructure will be able to deploy tacit- knowledge fine-tuned models that train continually on their own decision data, with training, inference and storage workloads remaining within Australian jurisdiction. Management Commentary David Brudenell, Executive Chairman of DAI said of the partnership: “The agentic economy runs on inference, and inference runs on infrastructure. Partnering with SCX.ai gives Decidr customers a domestic, high-performance foundation on which to deploy their own fine-tuned models with confidence. It is the Australian node in a broader multi-jurisdiction architecture we are building to meet enterprise demand for sovereign AI globally.” David Keane, CEO of SCX.ai: “Decidr is one of the most sophisticated buyers of sovereign inference in the Australian market. Together with Decidr we will give Australian enterprises and government customers the ability to run agentic AI on infrastructure that is unambiguously inside Australian jurisdiction.” Outlook The SCX.ai partnership accelerates Decidr’s Knowledge Security roadmap, supports the Company’s commercial activity with Australian enterprise and government customers, and forms the Australian foundation of Decidr’s multi-jurisdiction sovereign inference architecture. Decidr will provide further updates on customer deployments and additional sovereign infrastructure partners in due course. It is not currently possible to estimate the immediate financial impact on Decidr or the Company. However, the Company considers this to be a significant step in Decidr’s strategy to offer sovereign knowledge infrastructure to Australian customers. There is no other material information relevant to assessing the impact of the commercial partnership with SCX.ai on the price or value of the Company’s securities. -Ends- For further information, please contact: David Brudenell Executive Chairman, Decidr AI Industries Ltd E: dbrudenell@decidrindustries.ai Juan Hendy Investor Relations Manager, Decidr AI Industries Ltd E: juan.hendy@decidr.ai This announcement has been authorised for release by the Board of DAI.
