Ticker approval marks a key regulatory milestone for the listing of the business combination between VivoPower's subsidiary Tembo e-LV, and Cactus Acquisition Corporation I (CCTS)

Tembo has previously announced securing of strategic long term investment capital from the Emirates and hence no structured PIPE capital will be required

VivoPower expects to retain a significant equity interest in Tembo following completion of the business combination and separate listing of Tembo

LONDON, March 26, 2026 (GLOBE NEWSWIRE) -- VivoPower PLC (NASDAQ:VIVO) ("VivoPower" or the "Company"), a leading B Corp-certified global developer and owner of powered land and data center infrastructure for AI compute applications, today announced that Nasdaq has approved the reservation of the ticker symbol "TEMB" for Tembo Group N.V ("Tembo Group"), the combined entity to be formed following the business combination between VivoPower's wholly-owned subsidiary, Tembo e-LV B.V. ("Tembo e-LV"), and Cactus Acquisition Corporation I (OTC:CCTSF) ("CCTS").

This ticker approval represents a significant regulatory milestone in the progression of the business combination and proposed listing. Upon completion, Tembo Group will have its ordinary shares and public warrants listed on Nasdaq under the ticker symbols "TEMB" and "TEMBW", respectively.

Upon completion of the business combination, VivoPower expects to retain a significant equity interest in Tembo Group N.V., subject to final transaction mechanics, including CCTS redemptions and other closing conditions. The business combination values Tembo at a pre-money indicative equity value of approximately US$838 million.

Transaction Status and Next Steps

The transaction is subject to a number of final closing conditions, including:

The Registration Statement on Form F-4 being declared effective by the U.S. Securities and Exchange Commission (SEC);
Confirmation of CCTS shareholder approval; and
Other customary conditions.

The parties continue to work toward completion of the transaction as soon as practicable and will provide further updates as appropriate.

As previously announced, Tembo has previously secured long term strategic investment capital from the Emirates and no structured PIPE capital is required and will not be considered. The proposed listing of Tembo as a separately traded public company is intended to unlock value for VivoPower shareholders while enabling Tembo to access growth capital directly.

This announcement does not constitute an offer to sell or a solicitation of an offer to buy any securities, nor shall there be any sale of securities in any jurisdiction in which such offer, solicitation, or sale would be unlawful prior to registration or qualification under the securities laws of any such jurisdiction. No assurance can be given that the business combination will be completed or that Tembo Group's securities will be listed on Nasdaq.
