Termination of Form F-3 Registration Statement

On March 18, 2026, VivoPower PLC (the “Company” or “VivoPower”) announced that it has formally terminated its Form F-3 registration statement (File No. 333-292437) dated December 23, 2025, which was granted effectiveness on January 21, 2026 (the “F-3 Registration Statement”).

The F-3 Registration Statement provided for the potential sale of the Company’s ordinary shares. The Company confirms that no shares will be issued or sold pursuant to this F-3 Registration Statement.

The decision to terminate the F-3 Registration Statement 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 raising.

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).

The words “anticipate,” “believe,” “continue,” “could,” “estimate,” “expect,” “intends,” “may,” “might,” “plan,” “possible,” “potential,” “predict,” “project,” “should,” “would” and similar expressions may identify forward-looking statements, but the absence of these words does not mean that a statement is not forward-looking.

These statements are based on VivoPower’s management’s current expectations or beliefs and are subject to risk, uncertainty, and changes in circumstances.

The information set forth herein should be read in light of such risks. VivoPower is under no obligation to, and expressly disclaims any obligation to, update or alter its forward-looking statements whether as a result of new information, future events, changes in assumptions or otherwise.
