Senegal Joint Venture Progression to Implementation Phase

Eco Buildings Group plc (the "Company" or the "Group"), a UK-listed modular construction company specialising in sustainable GFRG-based building systems, is pleased to provide a further update on its strategic joint venture in Senegal with Eco Buildings' local partner, G2 Invest Group ("G2", together the "JV").

Advancement to Next Stage of Investment and Deployment

Following continued strategic engagement with G2, the Company is pleased to confirm that the parties have formally agreed to progress to the next stage of implementation of the Senegal manufacturing and housing programme.

Under the structure for the new production line in Senegal, G2's 35% equity stake in the JV equates to a capital contribution of €1.75 million, which has now been allocated into the JV subsidiary, Eco Buildings Senegal LLC. As previously announced by the Company in 2025, this payment is intended to support the operational scaling of Eco Buildings Senegal LLC and is designated for the establishment of a local manufacturing production line and the delivery of in-country project deployment. The contribution fulfils G2's agreed equity commitment in full and marks a significant milestone in the JV's development, aligning both parties ahead of operational deployment.

Mobilisation of Production Line

The Company is pleased to announce that the mobilisation process for the new Senegal-based production line has now commenced. The facility will be dedicated to fulfilling Senegalese housing demand under the previously announced framework.

The Company confirms that the engagement with its EPC contractor has formally begun, initiating the engineering, procurement and construction planning process for the deployment of the manufacturing line.

Show House Deployment for Final Government Approval

As part of the agreed next phase, the JV will proceed with the shipment and installation of a fully constructed Eco Buildings show house in Senegal.

The show house will be fully funded by the local partner and is intended to support final governmental approvals and facilitate the formalisation of programme roll-out. This step represents a key commercial and regulatory milestone toward large-scale delivery.
