Notification of Interest re Exit Opportunity

Defenx PLC (AIM: DFX), the cyber-security software group, announces that, further to BV Tech's announcement on 4 December 2019 of the Exit Opportunity to Minority Shareholders, the Company has been notified by BV Tech that it acquired a further 200,186 and 41,250 Ordinary Shares on 18 and 19 December 2019 respectively at 3 pence per share, being the purchase price pursuant to the Exit Opportunity.

Following the purchase of such Ordinary Shares, BV Tech is now interested in 29,360,459 Ordinary Shares, representing approximately 75.85 per cent. of the existing issued Ordinary Shares and voting rights in the Company. Accordingly, in light of BV Tech's shareholding being over 75% of the Company's issued share capital and pursuant to the irrevocable undertaking provided by BV Tech to vote in favour of the Resolutions to be proposed at the Company's forthcoming General Meeting on 20 December 2019, the Directors believe the Cancellation will now be approved.

Unless otherwise defined herein, capitalised terms used in this announcement shall have the same meaning as those used in the Company's announcement of 4 December 2019.
