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

Result of Retail Offer

Further to the announcement dated 30 August 2023, Rosslyn (AIM: RDT), the provider of a leading cloud-based enterprise data analytics platform, announces that, following the closing of the Retail Offer by BookBuild earlier today, 3,101,200 Retail Offer Shares will be issued at 0.5 pence per Retail Offer Share in connection with the Retail Offer.

The Company notes that approximately 89 per cent. of the £3.3 million raised via the conditional Placing and Subscription, and the issue of Convertible Loan Notes comprised existing shareholders in the Company. Furthermore, the issue price of 0.5 pence per Retail Offer Share represented a nil discount to the closing mid-market price on 29 August 2023, being the latest practicable date prior to the date of the announcement of the Fundraise.

Consequently, 517,000,000 Placing Shares, 23,000,000 Subscription Shares and 3,101,200 Retail Offer Shares, resulting in a total of 543,101,200 Fundraising Shares, will be issued in relation to the Placing, Subscription and Retail Offer, raising total gross proceeds of approximately £3.32 million.

The Fundraise is conditional on, inter alia, the passing of the Resolutions by Shareholders at the General Meeting to be held on 18 September 2023. It is expected that First Admission of the Fundraising Shares to trading on AIM will occur no later than 8.00 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.

Capitalised terms used but not defined in this announcement have the same meanings as set out in the circular to Shareholders dated 31 August 2023.
