Rosebank Industries plc

Results of the Institutional Capital Raise

Rosebank is very pleased to announce that, further to its announcement earlier today (the "Transaction Announcement"), it has successfully raised gross proceeds of approximately £1.9 billion via the issue of 575,757,575 New Ordinary Shares at the Issue Price of £3.30 per share through the Institutional Capital Raise.

In addition, at the same time as the Institutional Capital Raise, the Rosebank Directors and certain senior Rosebank employees and associates have subscribed for approximately £12.3 million, in aggregate, of New Ordinary Shares at the Issue Price (the "Connected Persons Subscription"), resulting in a cumulative investment to date of approximately £30.4 million since Rosebank's incorporation in 2024.

As set out in the Transaction Announcement, Rosebank has entered into two separate agreements to acquire MW Components and CPM, both US-based market-leading industrial businesses, for a total consideration of $3.05 billion⁽¹⁾ (~£2.28billion) on a debt and cash-free basis. Rosebank will finance the acquisitions of MW Components and CPM through the Institutional Capital Raise and new debt facilities.

Pursuant to Rule 14 of the AIM Rules, the Company's Existing Ordinary Shares will remain suspended from trading on AIM until the Admission Document is published, which is expected to be at or around 7.00 a.m. (London time) on or around 6 March 2026.

Subject to the approval of the Transaction Resolutions by Rosebank shareholders at the General Meeting on 23 March 2026, Admission of the New Ordinary Shares is expected to take place at 8.00 a.m. (London time) on 25 March 2026 and dealings in the New Ordinary Shares are expected to commence at that time. Subject to the satisfaction or, where appropriate, waiver of the conditions to the Transaction, it is expected that Transaction Completion will occur in the second quarter of 2026.

Rosebank intends to complete the admission of its ordinary shares to the Equity Shares (Commercial Companies) (ESCC) category of the Official List and to trading on the Main Market for listed securities of the London Stock Exchange in Q2 2026, irrespective of whether or not the Transaction proceeds, subject to receipt of all necessary regulatory consents and the publication of an FCA approved prospectus. If Transaction Completion occurs before Rosebank's move to the Main Market, in accordance with AIM Rule 14, the admission of the Ordinary Shares on AIM will be cancelled and application will be made for readmission of the Enlarged Group to trading on AIM.

Simon Peckham, Rosebank CEO, said:

"We thank our shareholders and lending partners for their ongoing support as Rosebank builds on the momentum of its first acquisition, ECI, with the addition of two more businesses, MW Components and CPM, with strong potential for improvement. Alongside ECI, MW Components and CPM significantly strengthen our ability to drive sustained profit improvement and deliver attractive shareholder returns as we continue to execute our proven "Buy, Improve, Sell" strategy."

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.
