Clarification re Eco Buildings over €400m Chile Contract

Accelerated Schedule and Increased Year-One Deliveries

Further to the Company's announcement on 21 October 2025 regarding the initial 50% deposit of €12.75 million received pursuant to the Chilean government's flagship housing programme, the Company wishes to clarify that this amount relates to the construction of 1,214 homes, not 607 homes as previously stated. The revised figure reflects a variation from the original contract following the Chilean housing authorities' agreement to accelerate the schedule of delivery in Year One, under which the total number of homes to be delivered under the first tranche has been increased accordingly.

All other information in the announcement on 21 October 2025 remains unchanged, including the initial deposit payment of €12.75 million which will be used to fund the initial production lines, the overall contract value of approximately €420 million and the total programme of 20,000 homes over seven years.
