Exercise of Warrants

Defence Holdings PLC (ALRT) announces that it has received notices from warrant holders to exercise warrants over a total of 69,800,000 ordinary shares of £0.001 each in the Company (“Ordinary Shares”).

Accordingly, the Company will issue 69,800,000 new Ordinary Shares to the warrant holders. Of these, 59,800,000 Ordinary Shares will be issued to a single warrant holder pursuant to the exercise of their warrants. The relevant shares have been sold by that holder, ensuring that no material block of stock will come to market following issue.

Admission and Total Voting Rights

Application will be made for the 69,800,000 new Ordinary Shares, which will rank pari passu with the existing Ordinary Shares in issue, to be admitted to trading on the London Stock Exchange Main Market ("Admission"). Dealings are expected to commence on or around 6 October 2025.

Following Admission, the Company's total issued and voting share capital will consist of   2,078,666,131 Ordinary Shares. The Company does not hold any ordinary shares in treasury.

Therefore, the above figure may be used by shareholders in the Company as the denominator for the calculation by which they will determine if they are required to notify their interest in, or a change to their interest in, the share capital of the Company under the FCA's Disclosure Guidance and Transparency Rules.
