LONDON, July 1, 2025 — VivoPower Receives NASDAQ Letter Confirming Recompliance with Listing Standard

VivoPower International PLC (Nasdaq: VVPR) (“VivoPower” or the “Company”) announced that it has received a letter from The Nasdaq Stock Market (“Nasdaq”) stating that, based on the Company’s Form 6-K, dated June 26, 2025, Nasdaq has determined that the Company complies with the Listing Rule 5550(b)(1), which requires listed companies to maintain a minimum of US$2,500,000 in stockholders’ equity for continued listing on the Nasdaq Capital Market (the “Rule”).

As previously disclosed, on January 3, 2025, the Company received a notification letter from Nasdaq indicating that the Company was not in compliance with the Rule. As disclosed in the Company’s audited financial statements for the fiscal year ended June 30, 2024, the Company reported a stockholders’ equity deficit of US$40.5 million. Following the successful completion of the first phase of the previously disclosed private placement of US$121 million equivalent of the Company’s ordinary shares, the Company recognized gross proceeds of US$60.5 million. As a result, the Company has now satisfied the stockholders’ equity requirement.

Nasdaq will continue to monitor the Company’s ongoing compliance with the minimum stockholders’ equity requirement and, if at the time of its next periodic report for the year ended June 30, 2025, the Company does not evidence compliance with the minimum stockholders’ equity requirement, the Company may be subject to delisting. At such time, Nasdaq staff will provide written notification to the Company, which may then appeal the Nasdaq staff’s determination to a Hearings Panel.

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).
