Change of Chair

Memphasys Limited (ASX: MEM) ("Memphasys" or "the Company") advises that Dr. Lindley Edwards has resigned as Non-Executive Chair of the Company, effective 18 May 2026, for personal reasons. The Board acknowledges and thanks Dr. Edwards for her contribution during her tenure and wishes her well.

Appointment of Non-Executive Chairman - David Tasker

The Board is pleased to announce the appointment of Mr David Tasker as Non-Executive Chairman, effective immediately.

Mr Tasker is the Managing Director and co-founder of Chapter One Advisors, a Perth-based, strategy and outcomes-focused boutique investor relations and media relations agency. He brings more than two decades of experience across investor relations, corporate communications, and capital markets advisory - including more than 13 years as National Director, Investor Relations at PPR, at the time one of Australia's largest integrated public relations companies.

He holds a Bachelor of Commerce (Marketing and Management) from Murdoch University.

Mr Tasker has provided investor relations and communications consulting services to Memphasys for more than 7 years and is a longstanding and significant shareholder of the Company. This combination of deep operational knowledge, strong stakeholder relationships, and direct shareholder alignment positions him well to support the Company's continued commercial progress as a Non-Executive Chairman.

On his appointment, Mr Tasker commented:

"I am honoured to take on the Chairman role at what is a genuinely exciting time for Memphasys. Felix™ has moved beyond clinical validation into active commercial execution - with growing order flow from key MENA partners, CE Mark approval now unlocking Europe and multiple CE-recognised markets, and a lean, focused team delivering real results on the ground. I look forward to continuing to support Hassan and Marjan at an operational level as the Company accelerates the execution and delivery of commercial agreements, and to working alongside all shareholders in the pursuit of sustainable returns from this outstanding technology."

Recent Commercial Progress

Mr Tasker's appointment comes as Memphasys continues to build meaningful commercial momentum across multiple key markets. Recent milestones include:

• Record March 2026 quarter revenue exceeding A$100,000, representing the Company's transition to a revenue-generating business, with repeat cartridge orders across Europe, MENA and Japan underpinning a recurring revenue model.¹
