Further to the announcements on 6 June 2025, Rosebank has today published the Admission Document, which will be posted to shareholders and contains the Notice of General Meeting.

The acquisition of ECI constitutes a reverse takeover for the purposes of Rule 14 of the AIM Rules and, accordingly, is conditional upon, among other things, the approval of Rosebank's shareholders. Rosebank's shareholders will also be asked to approve the Transaction Resolutions in addition to the renewal of certain standing authorities to allot shares and disapply pre-emption rights based on the Enlarged Share Capital. Accordingly, the General Meeting will be convened for 11:00 a.m. (London time) on 1 July 2025 at the offices of Investec Bank plc, 30 Gresham Street, London, EC2V 7QP.

In addition to the Institutional Capital Raise and the Connected Persons Subscription, Rosebank is proposing to raise up to approximately £6.7 million (before expenses) by way of the Open Offer at the issue price of £3.00 per share. Further details in relation to the Open Offer are provided in the Admission Document.

Following the publication of the Admission Document, and in accordance with AIM Rule 14, the Company's ordinary shares will be restored to trading on AIM from 7:30 a.m. on 11 June 2025.

The Admission Document is available on the Company's website at: https://www.rosebankindustries.com/

Information to distributors

Solely for the purposes of the product governance requirements of Chapter 3 of the FCA Handbook Product Intervention and Product Governance Sourcebook (the "UK Product Governance Requirements"), and/or any equivalent requirements elsewhere to the extent determined to be applicable, and disclaiming all and any liability, whether arising in tort, contract or otherwise, which any "manufacturer" (for the purposes of the UK Product Governance Requirements) may otherwise have with respect thereto, the New Ordinary Shares have been subject to a product approval process, which has determined that the New Ordinary Shares are: (i) compatible with an end target market of retail investors and investors who meet the criteria of professional clients and eligible counterparties, each as defined in Chapter 3 of the FCA Handbook Conduct of Business Sourcebook; and (ii) eligible for distribution through all permitted distribution channels (the "Target Market Assessment"). Notwithstanding the Target Market Assessment, "distributors" (for the purposes of the UK Product Governance Requirements) should note that: the price of the New Ordinary Shares may decline and investors could lose all or part of their investment; the New Ordinary Shares offer no guaranteed income and no capital protection; and an investment in the New Ordinary Shares is compatible only with investors who do not need a guaranteed income or capital protection, who (either alone or in conjunction with an appropriate financial or other adviser) are capable of evaluating the merits and risks of such an investment and who have sufficient resources to be able to bear any losses that may result therefrom. The Target Market Assessment is without prejudice to any contractual, legal or regulatory selling restrictions in relation to the Placing. Furthermore, it is noted that, notwithstanding the Target Market Assessment, the Joint Global Coordinators will only procure investors who meet the criteria of professional clients and eligible counterparties.

For the avoidance of doubt, the Target Market Assessment does not constitute: (a) an assessment of suitability or appropriateness for the purposes of Chapters 9A or 10A respectively of the FCA Handbook Conduct of Business Sourcebook; or (b) a recommendation to any investor or group of investors to invest in, or purchase, or take any other action whatsoever with respect to the New Ordinary Shares.

Each distributor is responsible for undertaking its own target market assessment in respect of the New Ordinary Shares and determining appropriate distribution channels.

Notice to Canadian Investors

The distribution of Placing Shares in Canada is to be made on a private placement basis only, exempt from the requirement that the Company prepare and file a prospectus with the relevant Canadian securities regulatory authorities and only to those who are both "accredited investors" within the meaning of National Instrument 45-106 - Prospectus Exemptions (or section 73.3(1) of the Securities Act (Ontario), as applicable) and "permitted clients" within the meaning of National Instrument 31-103 - Registration Requirements, Exemptions and Ongoing Registrant Obligations. In connection with any such sale made to investors in the Placing that are located in Canada, the Placee will be required to provide a signed investor qualification statement, confirming its eligibility to participate in the Placing.

The Company is not a "reporting issuer", as such term is defined under applicable Canadian securities legislation, in any province or territory of Canada, its securities are not listed on any stock exchange in Canada and there is currently no public market for the Placing Shares in Canada. The Company currently does not intend to file a prospectus or similar document with any securities regulatory authority in Canada qualifying the resale of the Placing Shares to the public in any province or territory of Canada or listing its securities on any stock exchange in Canada. Therefore, there will be no public market in Canada for the Placing Shares and the resale or transfer of the Placing Shares will be subject to restrictions. Accordingly, any resale of the Placing Shares of the Company must be made in accordance with applicable securities laws, and which may require resales to be made in accordance with exemptions from registration and prospectus requirements.

Securities legislation in certain provinces or territories of Canada may provide a purchaser with remedies for rescission or damages if this offering memorandum (including any amendment thereto) contains a misrepresentation, provided that the remedies for rescission or damages are exercised by the purchaser within the time limit prescribed by the securities legislation of the purchaser's province or territory. The purchaser should refer to any applicable provisions of the securities legislation of the purchaser's province or territory for particulars of these rights or consult with a legal advisor.

The Announcement is not, and under no circumstances is it to be construed as, an advertisement or a public offering of the Placing Shares in Canada. No securities commission or similar regulatory authority in Canada has reviewed or in any way expressed an opinion about the Placing Shares and any representation to the contrary is an offence.
