FOR IMMEDIATE RELEASE

16 February 2026

Rosebank Industries plc

Potential Transaction

Further to the recent press speculation, Rosebank Industries plc ("Rosebank" or the "Company") confirms that it is in advanced discussions regarding the potential acquisition of two private equity-owned US-based businesses (the "Potential Transaction") for a headline enterprise value of approximately $3.05 billion.

Rosebank notes that the Potential Transaction is in line with the Company's acquisition criteria and, if it proceeds, would be funded through a combination of a fully underwritten equity issue of approximately £1.9 billion (the "Fundraise") and new debt facilities. The Fundraise would be executed by way of a firm placing concurrent with a retail offer of up to £10 million for UK retail shareholders and investors.

The Company confirms that, irrespective of whether the Potential Transaction proceeds or not, it intends to complete its move to the Main Market of the London Stock Exchange in Q2 2026.

Temporary suspension of trading

As per AIM Rule 40, dealings in the Company's ordinary shares have been temporarily suspended from trading on AIM with immediate effect until such time as the MTF admission prospectus in relation to the Potential Transaction has been published in compliance with AIM Rule 14. If the Potential Transaction does not proceed and an MTF admission prospectus has not been published, an announcement will be made and the suspension from trading of Rosebank ordinary shares will be lifted.

Notwithstanding the temporary suspension of trading in the ordinary shares, the Company will continue to make announcements as and when there are any developments that require announcement under the AIM Rules.
