Veteran Banker and Licensed Fiduciary to Serve on the Audit Committee and the Compensation, Nomination and Governance Committee

MindWalk Holdings Corp. ("MindWalk") (NASDAQ: HYFT), a Bio-Native AI company, today announced the appointment of Kim Remizowski to its Board of Directors as an independent director, effective September 29, 2026. Mr. Remizowski will serve on the Audit Committee and the Compensation, Nomination and Governance Committee. The Board has determined that he qualifies as an independent director under Nasdaq listing rules and as an audit committee financial expert under applicable SEC rules. With this appointment, the Board comprises four directors, three of whom are independent.

Mr. Remizowski most recently served as Director, Private Equity at Vistra, a global corporate services group operating in more than 50 jurisdictions, where he oversaw governance for a portfolio of investment funds and holding structures. He brings more than 35 years of experience in institutional banking and fiduciary oversight, including board service at Merrill Lynch Bank and Trust Company (Cayman) Ltd., Managing Director responsibility at DMS Bank & Trust Ltd., and 17 years at Royal Bank of Canada. A Caymanian, he has spent the greater part of his career in the Cayman Islands financial services sector and is an Accredited Director of the Chartered Governance Institute of Canada and a Licensed Director with the Cayman Islands Monetary Authority (CIMA).

The appointment comes as MindWalk expands contracted, recurring platform deployments with life sciences clients on ReefIQ™, the biological data substrate that provides context for life sciences, powered by HYFT® Technology. Serving regulated life sciences workloads puts data integrity and governance at the center of the Company's value proposition and raises the premium on independent financial and governance oversight at the Board level.

"Kim brings the kind of governance depth that becomes load-bearing exactly when a company moves from building technology to deploying it at scale," said Jennifer Bath, PhD, President and Chief Executive Officer of MindWalk. "We are selling infrastructure into regulated life sciences workloads, and the credibility of that position rests as much on the quality of our governance as on the quality of the science. Kim has spent 35 years inside regulated financial institutions as a bank director and licensed fiduciary, and he brings that governance discipline to our Board and its committees. We are pleased to welcome him to the Board."

"MindWalk is building foundational infrastructure for life sciences AI and holding itself accountable for how that infrastructure is governed. That is a discipline I recognize from the institutional side of finance," said Mr. Remizowski. "I look forward to working with Dr. Bath, the Chair, and my fellow directors, and to bringing the rigor of regulated financial oversight to the Board's committees as the Company scales."
