Advisory Council Update

On July 17, 2026, VivoPower PLC (“VivoPower” or the “Company”) announced that Mr. Adam Traidman will be concluding his role as Chairman of the Company’s Board of Advisors.

Mr. Traidman joined the Company’s Board of Advisors as Chairman in May 2025, in connection with the Company’s capital raise and the launch of its digital asset treasury strategy. A former board member of Ripple and co-founder of several blockchain ventures, he was engaged to advise on matters relating to digital assets, blockchain technology and the XRP Ledger ecosystem.

As the Company’s focus has increasingly centered on the development and scaling of its powered land and data center digital infrastructure, with operations spanning Norway, Finland and the United Arab Emirates, the Company and Mr. Traidman have mutually agreed that this is a natural point to conclude his advisory engagement.

The Company would like to thank Mr. Traidman for his contributions and confirms that his departure did not result from any disagreement with the Company on any matter relating to its operations, policies or practices and should it be relevant and appropriate in future, would look forward to engaging with Mr. Traidman again.

This Report on Form 6-K, is hereby incorporated by reference into the Company’s Registration Statements on Form S-8 (File Nos. 333-227810, 333-251546, 333-268720, 333-273520) and Form F-3 (File No. 333-292437).
