Built Cybernetics plc

("Built Cybernetics", the "Company," or, together with its subsidiaries, the "Group")

Director/PDMR Exercise of Warrants and Total Voting Rights

Investor Presentation at Mello2025

Built Cybernetics plc (AIM: BUC), the Smart Buildings Group, confirms that, further to its announcement on 29 April 2025, the exercise of warrants to subscribe for ordinary shares of one penny each in the Company ("Ordinary Shares") by certain directors/PDMRs has now been completed.

In aggregate, 14,000,000 new Ordinary Shares have been allotted and issued. Total gross proceeds of £140,000 have been received by the Company. Full details of the exercise of warrants are set out in the Company's announcement on 29 April 2025.

Admission to Trading and Total Voting Rights

Application has been made to the London Stock Exchange for admission ("Admission") of the 14,000,000 new Ordinary Shares to trading on AIM. It is expected that Admission will occur on or around 21 May 2025.

Following Admission, the Company's issued ordinary share capital will consist of 355,072,100 Ordinary Shares, with one vote per share. The Company does not hold any Ordinary Shares in treasury. Therefore, on Admission, this figure may be used by shareholders in the Company as the denominator for the calculations 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.

Nick Clark, Freddie Jenner, and Jason Brameld (respectively the Group's Chief Executive, Chief Operating Officer, and Chief Technical Officer) are members of a concert party which collectively, following Admission, will be interested in 103,169,484 Ordinary Shares representing 29.06% of the Company's issued ordinary share capital.

There are now 23,500,000 warrants outstanding which, if exercised, would raise a further £235,000 for the Company.
