Calnex Solutions plc

("Calnex" or the "Company")

Notice of Annual General Meeting, Dividend timetable and posting of Annual Report

Calnex Solutions plc (AIM: CLX) provides test and measurement solutions for the global telecommunications sector and confirms that its Annual General Meeting ("AGM") will be held on 16 August 2023 at 9am at Oracle Campus, Linlithgow, EH49 7LR.

The Company's Annual Report and Accounts for the financial year ended 31 March 2023, along with the Notice of Annual General Meeting and a Form of Proxy, has been posted to shareholders and is available on the Company's website at: https://investors.calnexsol.com/.

AGM arrangements

The AGM will be held as a physical meeting, but the Company is pleased to offer the opportunity again for shareholders (or their duly appointed representatives and/or proxies) to participate remotely via Zoom, with the details of how to participate set out below. It would help the Company's planning if shareholders who wished to attend in person could email investors@calnexsol.com by no later than 5.30 p.m. on 1 August 2023 to confirm their wish to attend in order that the Company can be confident that the facilities proposed for the AGM will be able to accommodate attendance.

Details of any significant changes to the AGM arrangements will be published on the Company's website (https://investors.calnexsol.com/regulatory-news-alerts/) and shareholders are reminded that they can register for email alerts.

The Company is committed to encouraging shareholder engagement on the business of the AGM. As such, in addition to voting by proxy, shareholders (including any of their duly appointed proxies and/or corporate representatives) will be able to participate in the AGM by Zoom. Participating by Zoom will allow shareholders to view and listen to the AGM remotely and to follow the proceedings in real time as well as asking questions, if they are invited to do so. Please note, however, that shareholders will not be able to vote if participating by Zoom and it is therefore important that, if they wish to vote at the AGM, shareholders either physically attend the AGM or appoint a proxy to attend and vote on their behalf.

In order to participate by Zoom, shareholders will be required to pre-register by sending an email to investors@calnexsol.com by no later than 5.30 p.m. on 1 August 2023. Shareholders will then be sent by email a link to the Zoom meeting with detailed joining instructions.

The results of the voting will be available on the Company's website at https://investors.calnexsol.com/ as soon as practicable after the conclusion of the AGM.

Dividend timetable

As confirmed in the announcement of the Company's final results for the year ended 31 March 2023, released on 23 May 2023, the Company is proposing a final dividend of 0.62p per share. If approved by the passing of a resolution at the AGM, it is intended that the Dividend will be paid on 30 August 2023 to all shareholders on the register as at close of business on 28 July 2023, the record date.
