Rosslyn Data Technologies plc

("Rosslyn", the "Group" or the "Company")

Result of General Meeting

Rosslyn (AIM: RDT), the provider of a leading cloud-based enterprise data analytics platform, is pleased to announce that all four of the resolutions ("Resolutions") put to shareholders at the Company's General Meeting were duly passed.

The voting results will be made available on the Company's website shortly at https://www.rosslyn.ai/investors

Following the passing of the Resolutions at the General Meeting, the expected timetable of events remains the same as documented in the Circular, and is as follows:

Each of the times and dates refer to London (UK) time and are subject to change by the Company (with the agreement of Cenkos), in which case details of the new times and dates will be notified to the London Stock Exchange and the Company will, if appropriate, make an announcement through a Regulatory Information Service. Certain of the events in the above timetable are conditional upon, inter alia, the approval of the Resolutions to be proposed at the General Meeting.

References to times in this Announcement are to London (UK) time.

Application has been made for a total of 543,101,200 new Ordinary Shares in relation to Fundraising Shares and First Admission and dealings in the 543,101,200  new Ordinary Shares will commence at 08:00 a.m. on 19 September 2023.

Second Admission will occur after the Consolidation is effective and is expected to occur at 8.00 a.m. on 20 September 2023 (or such later times(s) and/or date(s) as Cenkos and the Company may agree).

The Fundraising Shares and the New Consolidated Ordinary Shares will, when issued, be credited as fully paid up and will have the same rights as the Existing Ordinary Shares including, voting, dividend, return of capital and other rights, and will on issue be free of all claims, liens, charges, encumbrances and equities.

Following Second Admission, the total number of New Consolidated Ordinary Shares in issue will be 17,659,275 with each New Consolidated Ordinary Share carrying the right to one vote. There are, and following Second Admission will be, no New Consolidated Ordinary Shares held in treasury and therefore the total number of voting rights in the Company will be 17,659,275. The above 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.

This announcement should be read in conjunction with the full text of the Circular posted to Shareholders on 31 August 2023, copies of which are available on the Company's website : https://www.rosslyn.ai/investors.  The same definitions apply throughout this announcement as are applied in the Circular.

Change of Name of Nominated Adviser
