Construction sites included in the order backlog as at 31 December 2025

The total order backlog is comprised of 14,067 individual projects. Approximately 13,500 of these, or 96%, involve very small or small orders with a volume of up to € 15 million each; the remaining proportion of 4% covers medium-sized to very large orders with contract volumes of € 15 million and up. A total of merely 65 projects have a volume above € 150 million. The high number of individual contracts guarantees that the risk involved with one project does not, as far as possible, threaten the Group success as a whole.
