Proposed Placing & Subscription and Notice of GM

Eco Buildings Group plc (AIM: ECOB) is pleased to announce that it has conditionally raised gross proceeds of £2,350,000 through the placing of 18,333,329 new Ordinary Shares (the "Placing Shares") and the subscription of 1,250,000 new Ordinary Shares ("Subscription Shares") both at a price of 12 pence per share (the "Placing Price") (together the "Fundraise"), through its broker Tavira Financial Limited ("Tavira"). The Fundraise is conditional, inter alia, on the passing of certain resolutions at a general meeting of the Company referred to below.

Use of Funds

The net proceeds of approximately £2.2 million will be used to fund the installation of a second GFRG manufacturing line in the Company's factory in Albania and for general working capital. The manufacturing line is expected to be installed within three to four months and to be operational immediately thereafter, allowing the Company to execute on its increasing order book in Albania as outlined in the recent announcement regarding the Balfin Group.

Warrants

In connection with the Fundraise, the Company has agreed to issue 9,791,664 warrants over new ordinary shares to placees, on the basis of one warrant for every two Fundraise Shares (the "Investor Warrants"). The Investor Warrants will be exercisable at 22 pence per ordinary share for a period of two years from Admission.

In addition, the Company has agreed to issue 1,100,000 warrants to Tavira (the "Broker Warrants" and, together with the Investor Warrants, the "Warrants"), exercisable at 12 pence per ordinary share for a period of two years from Admission.

Conditionality of the Placing and Subscription

The Fundraise is conditional, inter alia, upon:

• the placing agreement entered into between the Company and Tavira dated 19 May 2026 (the "Placing Agreement") not having been terminated in accordance with its terms prior to Admission;
• the passing of the Resolutions (as defined below) at the General Meeting (as defined below); and
• the admission of the Placing and Subscription Shares to trading on AIM ("Admission") becoming effective by no later than 8.00 a.m. on 5 June 2026 (or such later time and/or date as the Company and Tavira may agree, being not later than 8.00 a.m. on 18 June 2026).

In the event that any of the conditions to the Fundraise are not satisfied, the Fundraise will not proceed, no Placing Shares or Subscription Shares will be issued and no monies will be received by the Company pursuant to the Fundraise. In such circumstances, application monies received from placees will be returned to them (at the placees' risk and without interest) as soon as reasonably practicable thereafter.

General Meeting and refresh of authorities

The Directors do not currently have sufficient existing shareholder authorities to allot the Placing Shares (and the new ordinary shares to be issued on exercise of the Warrants) on a non-pre-emptive basis. The Placing is therefore conditional on shareholders approving the grant of new authorities to the Directors to allot the Placing Shares (and the new ordinary shares to be issued on exercise of the Warrants) and to disapply statutory pre-emption rights in respect of such allotments.

Accordingly, the Company will convene a general meeting (the "General Meeting") at which shareholders will be asked to consider and, if thought fit, pass resolutions (the "Resolutions") to:

• grant the Directors authority to allot the Placing Shares (and the new ordinary shares to be issued on exercise of the Warrants) and otherwise to refresh the Directors' general authority to allot shares in the capital of the Company; and
• empower the Directors to allot the Placing Shares (and the new ordinary shares to be issued on exercise of the Warrants) (and otherwise to allot equity securities) for cash on a non-pre-emptive basis.

The Directors who hold ordinary shares in the Company intend to vote in favour of the Resolutions in respect of their own beneficial holdings, amounting in aggregate to 17,640,286 ordinary shares and representing approximately 14.5 per cent. of the Company's existing issued ordinary share capital.

Shareholders should note that, if the Resolutions are not passed at the General Meeting, the Placing will not complete, the Placing Shares will not be issued and the Company will not receive the net proceeds of the Placing.

Related party transactions

The Fundraise does not constitute a related party transaction for the purposes of Rule 13 of the AIM Rules for Companies.

General Meeting

A circular convening the General Meeting to be held at 9.00 a.m. on 4 June 2026 at 160 Camden High Street, London, NW1 0NE will be sent to Shareholders today and will be available for download from the Company's website at www.eco-buildingsplc.com.

Admission and Total Voting Rights

Following the General Meeting, the Company will make an application for the 18,333,329 Placing Shares and 1,250,000 Subscription Shares to be admitted to trading on AIM at 8.00 a.m. on or around 5 June 2026.

Following the admission of the Fundraise Shares, the total issued share capital of the Company will be 140,987,383 ordinary shares, each with voting rights. The above figure 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.

Eco Buildings has already secured two sales contracts with major construction companies, one in Albania and the other in Kosovo, which are expected to generate gross sales revenue of up to approximately €38 million in total per annum over the first three years (approximately €114 million in total) following Admission.

The market share for factory-based building technology is expected to grow significantly over the coming years as private developers and the public sector seek to address the substantial and growing deficit in housing stock and issues of construction cost, speed, quality and housing affordability.

Definitions in this announcement are the same as those included in the Company's circular to be posted to shareholders today, dated 19 May 2026, available on the Company's website at www.eco-buildingsplc.com.

Introduction

The Company is pleased to announce that it had conditionally raised £2.35 million (before expenses) through the placing of 18,333,329 new Ordinary Shares ("Placing Shares") and the subscription of 1,250,000 new Ordinary Shares ("Subscription Shares") both at an issue price of 12 pence per share ("Issue Price"), (together, the "Fundraise") together with the issue of the Warrants.

The Fundraise is conditional upon, inter alia, Shareholder approval to authorise the Directors to allot the new Ordinary Shares and disapply statutory pre-emption rights at a general meeting, the Fundraise Shares being admitted to trading on AIM ("Admission") and the Placing Agreement not being terminated in accordance with its terms prior to Admission.

A circular will shortly be sent to Shareholders setting out the background to and reasons for the Fundraise and providing notice of the General Meeting to be held at 9.00 a.m. on 4 June 2026 ("General Meeting"). The General Meeting is being convened for the purpose of proposing the Resolutions described below and in the circular. The Directors intend to vote (or procure a vote) in favour of all of the Resolutions in respect of their own beneficial holdings totalling 17,640,286 Ordinary Shares, representing approximately 14.5 per cent. of the Existing Ordinary Shares in issue.

Current Trading

Eco currently operates one fully commissioned production line in Albania, which continues to operate at full production capacity in order to satisfy increasing regional demand for the Company's modular wall panel system. The Company continues to supply projects for the Balfin Group, including at its flagship Rolling Hills development, while also progressing additional opportunities with major developers and strategic partners across the Western Balkans region.

Demand for high-quality, energy-efficient and rapid-build housing solutions across the Western Balkans continues to increase significantly, driven by ongoing residential development, infrastructure investment and the growing requirement for modern sustainable housing stock. The Directors believe Eco is strategically positioned to benefit from this growing market demand through its scalable manufacturing model, proprietary technology and ability to deliver high-quality construction solutions at speed and at competitive cost.

Alongside its existing operations in Albania, the Company continues to make substantial progress internationally as it advances its strategy of establishing regional production capacity aligned to secured project opportunities and strategic partnerships.

In Chile, the Company continues to advance preparations relating to the establishment of local production facilities and remains engaged with local stakeholders and partners regarding significant long-term opportunities in the market. The Board believes Chile represents a substantial growth opportunity for Eco given the scale of demand for efficient and sustainable housing solutions.

In Senegal, Eco and its JV partner continue to advance operational activities and project development discussions in Dakar, with progress being made across multiple workstreams associated with the planned rollout of local production capacity and future residential development opportunities. The Company looks forward to updating the market further as these initiatives continue to progress.

The Board remains highly encouraged by the increasing level of engagement being received from developers, government-backed housing initiatives and strategic counterparties across multiple geographies. The Directors believe that current levels of demand and active discussions materially exceed the Company's existing production capacity, supporting the Board's strategy to expand manufacturing operations internationally in order to satisfy anticipated future demand.

Background to and reasons for the Placing

The purpose of the Placing is to raise funds to purchase a new GFRG production line. The Company has an existing line in Albania and is seeking to expand its production capacity to address anticipated demand from its sales pipeline.

At the annual general meeting of the Company held on 30 July 2025, Shareholders passed resolutions in order to: (i) grant the Directors authority to allot equity securities up to a maximum nominal value of £316,673.77; and (ii) disapply statutory pre-emption rights to allow the allotment by the Directors of equity securities for cash up to an aggregate nominal value of £191,923.50 without the requirement for such equity securities to be first offered to existing Shareholders. The issue of the Issue Shares, together with other relevant prior allotments, renders the second of these authorities insufficient to allow the Fundraise to proceed without further Shareholder approval. Accordingly, the issue of the Placing Shares and Subscription Shares is conditional on Resolutions 1 and 2 being passed.

Details of the Placing

The Ordinary Shares to be issued pursuant to the Fundraise will be credited as fully paid and rank equally with the existing issued Ordinary Shares when issued. The Placing is expected to become unconditional following approval of the Resolutions at the General Meeting and therefore Admission will be effective on or around 8.00 a.m. on 5 June 2026.

Fundraise

The Fundraise comprises the issue of 18,333,329 Placing Shares and 1,250,000 Subscription shares (together, the "Fundraise Shares") at the Issue Price to existing and new investors to raise a total of £2.35 million before expenses.

In connection with the Placing, the Company has entered into the Placing Agreement under which Tavira has agreed, in accordance with its terms, to use its reasonable endeavours to procure subscribers for the Placing Shares at the Placing Price. The Placing has not been underwritten by Tavira or any other person.

The Placing is conditional upon, inter alia, Shareholder approval of the Resolutions at the General Meeting, the Company allotting (subject only to Admission) the Placing Shares in accordance with the Placing Agreement, Admission of the Placing Shares to trading on AIM becoming effective by no later than 8.00 a.m. on 5 June 2026 (or such later time and/or date as the Company and Tavira may agree, being not later than 8.00 a.m. on 18 June 2026), the conditions in the Placing Agreement relating to the Placing being satisfied or (if applicable) waived, and the Placing Agreement not having been terminated in accordance with its terms prior to Admission.

The Placing Agreement contains a customary indemnity given by the Company to Tavira in respect of liabilities arising out of or in connection with the Placing. Tavira is entitled to terminate the Placing Agreement in certain circumstances prior to Admission.

General Meeting and refresh of authorities

A notice convening a General Meeting of the Company to be held at 160 Camden High street, London, NW1 0NE at 9.00 a.m. on 4 June 2026 is set out at the end of this document. The business to be considered at the General Meeting is set out in the Notice of General Meeting. Explanatory notes relating to each Resolution are set out below. The Issue is conditional upon, among other things, the passing of the Resolutions.

The Company is therefore proposing that Shareholders pass the Resolutions in order to:

Resolution 1: Authority to allot new shares

Resolution 1 is proposed as an ordinary resolution. This means that for this Resolution 1 to be passed, more than half of the votes cast must be in favour of the Resolution.

Resolution 1 is to grant the Directors the general authority to allot and issue shares in the Company and to grant rights to subscribe for or to convert any security into shares in the Company up to an aggregate nominal amount of £910,530.41, being 91,053,041. shares representing approximately 75 per cent. of the Company's issued share capital (as at the date of this letter). This authority is in substitution for all existing authorities to issue shares in the Company or to grant rights to subscribe for or to convert any securities into shares in the Company.

Unless revoked, varied, or extended this authority will expire at the conclusion of the next Annual General Meeting of the Company or 15 months from the passing of Resolution 1, whichever is the earlier.

Resolution 2: Disapplication of pre-emption rights

Resolution 2 is proposed as a special resolution. This means that for this Resolution 2 to be passed, at least three-quarters of the votes cast must be in favour of the resolution.

The Act also provides that any allotment of new shares for cash must be made pro rata to individual shareholders' holdings, unless such provisions are disapplied under section 570 of the Companies Act 2006. Resolution 2 will be proposed as a special resolution to grant the Directors' authority to allot equity securities for cash, without first offering them to shareholders pro rata to their holdings. This authority facilitates issues made by way of rights to shareholders which are not strictly in accordance with section 561(1) of the Act and authorises other allotments up to the maximum aggregate nominal value of £910,530.41, being 91,053,041 shares representing approximately 75 per cent. of the issued ordinary share capital of the Company (as at the date of this letter). This authority also allows the Directors, within the same aggregate limit, to sell for cash shares that may be held by the Company in treasury on a non-pre-emptive basis.

Unless revoked, varied, or extended this authority will expire at the conclusion of the next Annual General Meeting of the Company or 15 months from the passing of Resolution 2, whichever is the earlier.

Admission, Settlement and CREST

Application will be made to the London Stock Exchange for the Placing Shares to be admitted to trading on AIM. On the assumption that, inter alia, the Resolutions are passed, it is expected that Admission of the Placing Shares will become effective and that dealings in the Placing Shares will commence at 8.00 a.m. on 5 June 2026.

The Articles permit the Company to issue shares in uncertificated form. CREST is a computerised paperless share transfer and settlement system which allows shares and other securities to be held in electronic rather than paper form. The Ordinary Shares are already admitted to CREST and therefore the Placing Shares will also be eligible for settlement in CREST. CREST is a voluntary system and Shareholders who wish to retain certificates will be able to do so on request. The Placing Shares due to uncertificated holders are expected to be delivered in CREST on or around 5 June 2026.

Action to be taken by Shareholders in respect of the General Meeting

Shareholders will find enclosed with the circular a Form of Proxy for use at the General Meeting. Shareholders are strongly encouraged to complete, sign and return the Form of Proxy in accordance with the instructions printed on it as soon as possible, but in any event so as to be received, by post or, during normal business hours only, by hand, FAO Fungai Ndoro, 160 Camden High Street, London, NW1 0NE by 9.00 a.m. on 2 June 2026 (or, in the case of an adjournment, not later than 48 hours before the time fixed for the holding of the adjourned meeting (excluding any part of a day that is not a working day)). Alternatively, the Form of Proxy may be scanned and sent by email to proxies@eco-buildings.net so as to be received by 9.00 a.m. on 2 June 2026.

The appointment of proxies or the giving of any instruction by the CREST system will not be accepted for the purposes of the General Meeting.

Recommendation

The Directors believe that the Resolutions to be proposed at the General Meeting are in the best interests of the Company and Shareholders as a whole and unanimously recommend that Shareholders vote in favour of them as they intend to in respect of their own beneficial holdings totalling 17,640,286 Ordinary Shares, representing approximately 14.5 per cent. of the Existing Ordinary Shares.
