ROCKWOOD STRATEGIC PLC

("Rockwood Strategic" or the "Company")

Share Sub-division and Total Voting Rights

Further to the announcement on 4 October 2023 and in advance of the proposed sub-division of its existing ordinary shares on a ten for one basis (the "Share Sub-division") which will take effect from 11 October 2023, the Company announces it currently has in issue 2,687,909 Ordinary shares of 50 pence each in the capital of the Company (the "Existing Ordinary shares") and no shares are held in Treasury. 

On this basis and in accordance with the Financial Conduct Authority's Disclosure Guidance and Transparency Rules, following the completion of the Share Sub-division on 11 October 2023, the Company will have 26,879,090 Ordinary shares of 5 pence each in the capital of the Company (the "New Ordinary shares") in issue.

The New Ordinary shares will have a new ISIN and SEDOL, as follows:

ISIN: GB00BRRD5L66

SEDOL: BRRD5L6

Application has been made for the admission of the New Ordinary shares to the Official List of the Financial Conduct Authority and to trading on the main market of the London Stock Exchange and to amend the Company's existing block listing facility (the "Admission Applications"). The Admission Applications included the 361,345 Existing Ordinary shares remaining available for issue under the Company's current block listing facility. Upon the amendment of the block listing facility there will be 3,613,450 New Ordinary shares available for issue pursuant to the existing facility.

It is expected that the Share Sub-division will become effective and that dealings in the New Ordinary shares will commence at 8.00am on Wednesday, 11 October 2023. The last day of dealings in the Existing Ordinary shares will be today, Tuesday, 10 October 2023, with the record date for the Share Sub-division being 6.00pm today (the "Record Date"). CREST accounts are expected to be credited with New Ordinary shares on Wednesday, 11 October 2023 and share certificates in respect of the New Ordinary shares are expected to be dispatched to shareholders no later than 25 October 2023.

The above figure, 26,879,090, 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 Company, under the Disclosure Guidance and Transparency Rules.
