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 panels ("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.
