Result of Retail Offer

Further to the announcement dated 30 November 2023, RUA Life Sciences plc (AIM: RUA.L), the holding company of a group of medical device businesses focused on the exploitation of Elast-Eon?, the world leading long-term implantable biostable polyurethane, is pleased to announce that, following the closing of the Retail Offer on the BookBuild platform on 7 December 2023, 2,784,566 Ordinary Shares will be issued at the Issue Price of 11 pence per Retail Offer Share in connection with the Retail Offer, raising an additional £0.31 million.

Consequently, conditional on the passing of the Resolutions at the General Meeting (and, in relation to the Subscription Shares only, the announcement of Group's interim accounts ending the closed period), 36,363,636 Placing Shares, 727,272 Subscription Shares and 2,784,566 Retail Offer Shares, resulting in a total of 39,875,474 new Ordinary Shares, will be issued in relation to the Placing, Subscription and Retail Offer, raising total gross proceeds of £4.4 million.

Admission and Total Voting Rights

Application has been made for the Retail Offer Shares to be admitted to trading on AIM ("Admission"). Admission is expected to take place at 8.00 a.m. on or around 19 December 2023.

The Retail Offer 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 Admission, the total number of Ordinary Shares in the capital of the Company in issue will be 62,060,272 with each Ordinary Share carrying the right to one vote. There are no shares held in treasury and therefore, following Admission, the total number of voting rights in the Company will be 62,060,272. The above figure may be used by Shareholders 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 in this announcement have the meaning given to them in the Placing and Retail Offer announcement dated 30 November 2023, unless otherwise defined in this announcement.
