VivoPower Fully Retires US$28.8 Million Shareholder Debt Principal, Strengthening Balance Sheet Ahead of Nordic AI Infrastructure Buildout

On August 3, 2026, VivoPower PLC (the “Company” or “VivoPower”), announced the complete retirement of US$28.8 million of shareholder debt principal previously owed to its founding shareholder, AWN Holdings Limited (“AWN”), an entity affiliated with Executive Chairman and Chief Executive Officer, Kevin Chin.

Overview

	●	Complete retirement of US$28.8 million shareholder debt principal - 100% elimination of outstanding principal obligations to AWN

	●	US$16.5 million retired via PIPE 2 participation - AWN participated in the US$50 million PIPE 2 transaction announced on 29 July 2026, demonstrating founder alignment with UK, EU and Nordic-based institutional investors, committing to a minimum lock-up period of 6 months. 165,000 convertible preference shares were issued to AWN in exchange for the cancellation of US$16.5 million of debt

	●	US$12.3 million retired concurrently - the balance of the outstanding principal has been fully retired through payment in cash

	●	Balance sheet strengthening - the retirement of the debt owed to AWN eliminates the associated interest expense and materially improves credit quality ahead of Nordic AI infrastructure platform buildout

	●	Approval by independent board members - the transaction has been reviewed and approved by the Audit and Risk Committee of the Board, comprised solely of independent directors, under the Company’s Related Party Transactions Policy.

Following these transactions, VivoPower has no remaining principal balance outstanding under the historical AWN shareholder loan facility. Residual amounts, including any accrued interest, will be finalized and repaid in due course.

Historical Context

The AWN shareholder loan facility was originally established during the Company’s early public market period to support strategic development and working capital requirements. The facility has been referenced across prior disclosures by the Company, including in the Company’s Annual Report on Form 20-F filings and periodic Form 6-K disclosures with the U.S. Securities and Exchange Commission.

Related Party Transaction Disclosure

This transaction constitutes a related party transaction under applicable disclosure requirements, given the affiliation between AWN and Executive Chairman, Kevin Chin. The transaction has been:

	●	Reviewed and approved by the Audit and Risk Committee of the Board of Directors of VivoPower, comprising independent directors only

	●	Structured with the PIPE 2 participation component priced on terms identical to those available to third-party institutional investors.
