Six-month Report 2025
Management Report Financial ReportManagement Report

Dear shareholders,
In the first half of 2025, Zehnder Group's sales and operating result in the ventilation segment in Europe and North America increased significantly compared to the previous year. Sales in the ventilation segment grew both organically and through the acquisition of Siber in Spain in July 2024. Increased construction activity in some countries, the expansion of our market share, and a build-up of stock on the customer side had a positive impact on sales development. In contrast, sales in the radiator segment continued to decline.
Signs of recovery in various countries in the ventilation segment became more pronounced during the first half of the year. The positive trend indicates that demand has bottomed out in various countries. Nevertheless, uncertainty remains for the second half of 2025 due in part to the ongoing tariff situation in the USA. At the same time, the geopolitical situation is dampening general investment sentiment.
We want to further strengthen our market position through a focused strategy and targeted investments in innovation and sustainability. We are systematically pursuing our transformation into a leading international supplier of indoor climate systems.
In addition, we are continuing to expand our service and maintenance business with the aim of reducing our dependence on the new building cycle.
