Eco Buildings Secures Senegal JV to Deliver 900,000 m² / 5,000-Home Modular Housing Programme

JV with G2 Invest advances to execution phase; factory mobilisation underway and first-phase planning approvals expected before year-end

Eco Buildings Group plc (the "Company" or the "Group"), a UK-listed modular construction company, is pleased to announce a major milestone in its strategic joint venture in Senegal with G2 Invest Group, one of Dakar's leading logistics and facilities management companies.This milestone follows Eco Buildings' previously announced strategic framework for a 10,000-home programme in Senegal, demonstrating rapid progression from agreement to on-the-ground mobilisation.

Following the binding Memorandum of Understanding (MoU) signed earlier this year, the parties have now entered into a full Shareholders Agreement (the "Agreement") establishing the terms of the joint venture vehicle to be named, Eco Buildings Senegal Limited. In accordance with the Agreement and as previously announced, G2 Invest has committed to making an initial €1.75m payment into Eco Buildings Senegal LLC. This payment is expected to be received in December 2025. G2 Invest confirmed that phase one of the housing programme totaling approximately 900,000 m² of built-up floor area - equivalent to 5,000 homes - has been formally allocated to the joint venture. This programme will be delivered using Eco's proprietary modular building systems.

This marks a significant commercial inflection point for Eco Buildings as the project moves from planning into the execution and delivery phase.

Eco's modular system enables rapid, high-quality delivery at scale, providing a cost-effective solution to address significant housing deficits in emerging markets.Planning approvals are expected to be completed before year-end, reflecting the sequencing of regulatory and mobilisation steps. This will allow site works and factory deployment to begin immediately thereafter.Mobilisation of the first manufacturing line is underway, with deployment scheduled to align with the planning approval timetable, positioning the JV to commence site works immediately following regulatory sign-off.Dr Etrur Albani, Executive Vice Chairman of Eco Buildings Group plc, commented:

"This joint venture has now moved decisively from agreement to action. With the JV structure in place, factory mobilisation underway, final planning approvals expected before year-end, and a 5,000-home programme allocated, we are positioned to deliver meaningful scale in Senegal. This partnership combines Eco's proven modular technology and delivery capability with G2 Invest's strong local presence and government relationships. Together, we are addressing Senegal's housing challenge with speed, scale, and sustainability.

This first phase not only represents a significant revenue pipeline in its own right, but also establishes a strategic operational base from which Eco Buildings intends to replicate its modular housing model across other West African markets."
