Changes to concert party

Power Probe ("Power Probe", the "Group" or the "Company"), a leading producer of automotive electrical diagnostic tools for professional service technicians, was notified yesterday, 26 March 2026, of the following purchases of ordinary shares of 0.1 pence each in the capital of the Company ("Ordinary Shares"):

*Purchased via CHR International Projects Limited, a company wholly owned by Chema Garcia

Further details of the above dealings are set out at the end of this announcement.

The Concert Party

The Company has agreed with the Panel on Takeovers and Mergers that CHR International Projects (a company wholly owned by Chema Garcia) is presumed to be acting in concert with the members of the Concert Party (as defined below) in relation to the Company. Accordingly, there is presumed to be a single concert party, who together hold 53.4 per cent. of the Company's issued share capital (the "Concert Party"):

As set out in the Company's admission document dated 5 December 2025, it is the intention of So Wan to place in trust the shareholdings of JNC Ever Limited, Jubilant Inspirations Limited and Noble Character Limited for the benefit of So Wan, Ip Foo Wing, his spouse and their children (the "Ip Foo Wing Family Trust").

Upon the establishment of the Ip Foo Wing Family Trust, the aggregate interest of the Concert Party will be unchanged, but the individual interest of Ip Foo Wing and his spouse will increase to 24,954,940 Ordinary Shares, representing 33.9 per cent. of the voting rights of the Company.

Furthermore, Chema Garcia was granted an award under the Long Term Incentive Performance Share Plan adopted by the Company on 4 December 2025 (the "Performance Share Plan"), subject to certain performance-based and other vesting criteria, to receive nominal cost new Ordinary Shares, representing in aggregate 0.8 per cent. of the Company's issued share capital.

Following the establishment of the Ip Foo Wing Family Trust, and assuming full vesting of such awards under the Performance Share Plan, the Concert Party would be interested in aggregate in a maximum of 39,952,963 Ordinary Shares representing 53.8 per cent. of the Company's issued share capital at that time, assuming no other Ordinary Shares are issued.

The members of the Concert Party hold shares carrying more than 50 per cent. of the voting rights of the Company and (for so long as they continue to be acting in concert) no obligation to make an offer under Rule 9 of the City Code on Takeovers and Mergers will normally arise from acquisitions of interests in shares carrying voting rights by any member of the Concert Party.
