VivoPower Announces Effectiveness of New Stock Ticker “VIVO” and Corporate Name Change

LONDON, 16 March 2026 – VivoPower International PLC (“VivoPower” or the “Company”), a leading B Corp-certified global developer and owner of powered land and data center infrastructure for AI compute applications, is pleased to announce that effective today, before the open of trading on the Nasdaq stock market, its stock will be traded under the new ticker “VIVO”.

The Company has also officially completed its corporate name change to VivoPower PLC. Both the ticker and name change reflect the Company’s strategic focus on building, owning, and leasing powered land and data center infrastructure for AI compute applications.

The name change does not affect the rights of shareholders, and no action is required from current shareholders.

VivoPower’s core scope remains the provision of land, power, and real-estate infrastructure, while technology and operations remain under the domain of the lessor. The Company aggregates the scarcest input in the data center value chain—power-secured land—and monetizes these assets through long-term, bankable lease contracts with sovereign nations, hyperscalers, neocloud players, and other tenants.

A copy of the press release is attached hereto as Exhibit 99.1 and incorporated herein by reference.

This Report on Form 6-K, including Exhibit 99.1, 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).
