Results of the Institutional Capital Raise

Rosebank is very pleased to announce that, further to its announcement earlier today (the "Acquisition Announcement"), it has successfully raised gross proceeds of approximately £1.14 billion via the issue of 380 million New Ordinary Shares at an issue price of £3.00 per share.

As set out in the Acquisition Announcement, Rosebank has entered into an agreement to acquire ECI, a private US-based market leader in critical electrical distribution systems. Rosebank will finance the acquisition of ECI through debt facilities and a fully underwritten Institutional Capital Raise.

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 11 June 2025.

Subject to the approval of the Transaction Resolutions by Rosebank shareholders at the General Meeting on 1 July 2025, Admission of the New Ordinary Shares is expected to take place at 8.00 a.m. (London time) on 3 July 2025 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 Acquisition, it is expected that Acquisition Completion will occur in the third quarter of 2025. On Acquisition Completion, in accordance with AIM Rule 14, the admission of the Ordinary Shares will be cancelled and application will be made for Readmission of the Enlarged Group.

Rosebank's Chief Executive, Simon Peckham, said:

"We are grateful to our shareholders and lending institutions for their support of Rosebank's first acquisition. We are excited by the significant opportunities that ECI presents to drive profit improvements and deliver excellent returns for all shareholders as we employ Rosebank's "Buy, Improve, Sell" strategy and capitalise on its already strong market positioning and experienced management team."

Capitalised terms used in this announcement have the meanings given to them in the Acquisition Announcement, unless the context provides otherwise.

The person responsible for arranging for the release of this announcement on behalf of Rosebank is Joff Crawford.

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.

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.
