Terminationof At-the-Market Offering Agreement

On February 2, 2026, VivoPower International PLC (the “Company” or “VivoPower”) today announced that it has formally terminated its “at-the-market” equity offering agreement (the “ATM Agreement”) with Chardan Capital Markets, LLC, dated December 23, 2025.

The ATM Agreement provided for the potential sale of the Company’s ordinary shares under the Company’s Form F-3 shelf registration statement dated March 27, 2024. The Company confirms that no further shares will be issued or sold pursuant to this ATM Agreement.

The decision to terminate the ATM facility follows a review of the Company’s current operating cash flow outlook, capital requirements, potential alternative economically non-dilutive sources of capital, including at the project or asset level, and current market conditions. Management has determined that at this current time, its projected cash flow from operations, as well as current and projected economically non-dilutive sources of funding, obviate the need to raise ATM capital. This approach is consistent with the Board’s focus on disciplined capital allocation and avoiding, where possible, dilutive capital raisings.

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. 333-276509).
