MindWalk Showcases ReefIQ™ for AI Drug Discovery at AMD Advancing AI

At Advancing AI 2026, MindWalk unveils the first public demonstration of ReefIQ, its biological context layer for AI drug discovery, running on AMD Instinct™.

AUSTIN, Texas, July 23, 2026 — MindWalk Holdings Corp. (“MindWalk”) (NASDAQ: HYFT), a Bio-Native AI company, today unveiled the first public demonstration of ReefIQ™, its biological context layer for AI drug discovery, running on AMD Instinct™ at AMD’s Advancing AI 2026 in San Francisco. MindWalk is featured in the AMD Instinct™ Demo Showcase, appearing in one of four custom demo vignettes, with an accompanying video interview distributed through AMD’s channels.

The demonstration is the first time MindWalk has shown ReefIQ publicly in action. It walks through how ReefIQ reconnects fragmented discovery data into governed, queryable biological context, then lets AI models and agents reason over that context, running on open AMD Instinct compute. ReefIQ, which MindWalk introduced in June 2026, sits between client discovery data and AI reasoning workflows.

What ReefIQ is

Biology is connected, but drug-discovery data is often fragmented across files, formats, systems, teams, and workflows. ReefIQ reconnects those representations before AI workflows act on them. Sequences, structures, assay outputs, omics, literature, evidence, provenance, and program history become governed, queryable connected biological context for AI-enabled discovery.

HYFT® Technology is MindWalk’s core biological pattern technology, the biological representation foundation with explicit relationships across sequence, structure, function, mechanism, pathway, evidence, and literature. ReefIQ™ is the client biological context layer built on HYFT. LensAI™ is the reasoning and application layer. HYFT powers the biological representation. ReefIQ organizes and governs the context. LensAI applies reasoning workflows.

“In life-sciences AI, the durable advantage is not the model a team licenses but the biological context it can reason over. Biology is connected by evolutionary constraint; discovery data arrives fragmented across files and systems, and that gap is where insight is lost. ReefIQ is designed to close it, preserving what every program learns, including the programs that fail, as governed context rather than isolated files. In a regulated setting, that is what makes reasoning trustworthy, and trustworthy is what compounds into the clinic,” said Dr. Jennifer Bath, PhD, CEO and President of MindWalk Holdings Corp.

Why it matters

Drug-discovery organizations generate valuable context in every program: positive results, negative results, assay conditions, design decisions, mechanism hypotheses, literature links, and the reasons candidates did not advance. ReefIQ preserves that context as governed, queryable knowledge. As data are added, the network is enriched and its relationships and annotations are refined. Future programs benefit from the ever-compounding evidence and insights.

HYFT reasoning is grounded in evolutionary constraint, the patterns biology preserves because their function is non-negotiable, rather than statistical correlation. In regulated drug discovery, where a hallucinated result is a patient-safety and program-cost problem, that grounding is what makes reasoning, including autonomous and agentic reasoning, trustworthy enough to act on.

Why AMD Instinct

Bio-Native inference is data-dominated and memory-heavy: enrichment, similarity search across hundreds of millions of patterns, and reasoning over connected biological context. AMD Instinct’s memory-rich, open-stack, portable profile maps onto that workload. The architecture supports flexible integration across data governance, model access, and compute deployment, so a customer’s connected context stays in the customer’s environment under existing governance while inference runs on open compute.

“ReefIQ operationalizes the HYFT information network for drug discovery,” said Dirk Van Hyfte, MD, PhD, Chief Technology Officer of MindWalk AI. “HYFT provides the biological representation foundation, representing the complex relationships in biology; ReefIQ links customer data to that foundation and exposes governed context to LensAI and customer-selected agent models operating within agreed governance. The goal is to support retrieval, analysis, and hypothesis generation over connected biological context while preserving provenance, deployment flexibility, and customer-defined controls.”

What comes next

MindWalk’s Business Development team will use Advancing AI 2026 to engage life-sciences customers, infrastructure partners, and agentic-AI builders evaluating where to host and govern regulated biological context. LensAI is already in contracted, recurring arrangements with life-sciences customers today. Interested parties may request a private briefing through Investor Relations.
