Launch of Indonesia Subsidiary with a Local Partner

Highlights

·    Eco Buildings to establish a new subsidiary, Eco Buildings Indonesia LLC, to address major modular housing demand in Indonesia.

·    Binding MOU signed with local partner Messrs Cooper & Accors ("MCA"), experienced executives with 30+ years' regional expertise in construction and finance.

·    MCA has pledged to fund the establishment of a new Eco Buildings production line in Indonesia, with a committed investment of $5m.

·    Investment structured as $5m equity subscription for a 49% stake in the subsidiary, with all additional operational costs and local cashflows funded by MCA.

Eco Buildings Group plc, a UK-listed modular construction company, is pleased to announce that it is setting up a new subsidiary, Eco Buildings Indonesia LLC ("Eco Indonesia"), to address significant market opportunities for modular housing in Indonesia.

To support this expansion, Eco Buildings has entered into a binding memorandum of understanding ("MOU") with Messrs Cooper & Accors ("MCA"), a local partner comprised of two seasoned executives with over 30 years' regional experience in construction and finance.

This development is indicative of Eco Buildings' growth strategy and is consistent with the Company's geographic expansion, as previously disclosed in the Company's operational update announcement in October 2025.

To enable the rapid deployment of production capacity, MCA has pledged an initial $5 million equity subscription for a 49% stake in Eco Indonesia. This commitment from MCA is expected to cover the full costs associated with the installation of a new production line in Indonesia. The Company expects the production facility will be operational by the end of 2026.

The new production line is expected to provide the necessary scale to support broader housing delivery programmes in the region. MCA will be responsible for the day-to-day operations of Eco Indonesia, including the manufacturing facilities.

All operational costs, expenses and local cashflows associated with Eco Indonesia are to be funded by MCA, thereby reducing funding requirements for Eco Buildings at Group level.

Dr Etrur Albani, Executive Vice Chairman of Eco Buildings Group plc, commented:

"The launch of Eco Indonesia with MCA demonstrates the increasing global demand for our GFRG modular housing solutions and the effectiveness of our international expansion strategy. Indonesia is a region we have been actively targeting due to its scale and structural housing need.

This binding MOU represents a material step forward in converting that opportunity into a local operating platform capable of delivering revenues and cashflows. Importantly, the structure is designed to accelerate progress while limiting funding demands on the Group.

MCA's commitment to fund the production line and provide the operational cashflows reflects both the scale of the opportunity and their confidence in Eco Buildings' technology and delivery model."

Messrs Cooper & Accors, commented:

"We are excited to represent Eco Buildings Homes' GFRG building system in Indonesia. Indonesia's national target to deliver 3,000,000 affordable homes presents a significant opportunity for the deployment of a sustainable, cost efficient and durable construction solution aligned with the country's housing objectives."

The information communicated in this announcement is inside information for the purposes of Article 7 of Regulation 596/2014.

Notes

The Company has acquired proven and innovative prefabricated technology which has been in development and commercial use since 2006. Eco Buildings' range of prefabricated, green housing products based on glass fibre reinforced gypsum walls ("GFRG") provides a construction solution for both affordable and high-end housing.

Eco Buildings has already secured two sales contracts with major construction companies, one in Albania, the other in Kosovo, which are expected to generate gross sales revenue of approximately up to €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 and quality and housing affordability.
