Six-month Report 2026
Management ReportFinancial ReportManagement Report

Dear shareholders,
In the first half of 2026, Zehnder Group achieved further sales growth on the back of the strong ventilation segment. In Europe, we continued to grow our ventilation sales overall, while in North America we benefited from targeted expansion of our ventilation business. The general increase in the share of ventilation sales combined with efficiency improvements contributed to a higher operating margin, which increased the adjusted operating result at a faster rate than sales. By contrast, in the radiator segment, sales and the operating result remained under pressure despite the measures implemented.
Our innovation and market launch initiatives in Europe delivered positive results in the ventilation business. The share of sales generated by the Zehnder EVO product line for multi-family homes in Europe continued to increase, supported by product launches in additional countries. The planned development of our US business also progressed further during the first half of the year as we expanded into additional states and secured new projects, strengthening our overall presence in this key market.
Geopolitical tensions in the Middle East led to increased volatility in the energy and raw materials markets. Thanks to disciplined cost management, the impact on our business has so far remained limited.
In June 2026, we took the next steps in developing our organisational and management structures. Going forward, our European ventilation and radiator activities will be managed as separate divisions, each with its own profit and loss responsibility. This divisional structure will enable us to capitalise more effectively on the specific potential of each market, shorten decision-making processes, and tailor our segment strategies more precisely.
Although market conditions remain challenging in certain regions, we are encouraged by the progress in our ventilation business, our growing internationalisation, and our organisational realignment. We will continue to execute our strategy with consistency and focus, and remain committed to profitable growth and the sustainable enhancement of corporate value.
