Zehnder Group: Introduction of a divisional organizational structure

Organizational separation of European ventilation and radiator operations, with clear accountability for results in each division Realignment and reduction of the Group Executive Committee from six to five members One-off effects related to the adjustments of approximately EUR 10 million are expected for the 2026 fiscal year Confirmation of medium-term targets of around 5% average annual sales growth and an EBIT margin before one-off effects of 9–11%

Gränichen (CH), 19 June 2026: Zehnder Group (SIX: ZEHN), a leading international provider of complete solutions for a comfortable, energy-efficient, and healthy indoor climate, intends to adopt a new organizational structure per 1 October 2026. The activities in Europe, which have been closely integrated from an organizational standpoint, will be separated and managed with full accountability for results, so that both the ventilation and radiator segments can continue to develop optimally. The divisional structure will enable the future independent divisions, Residential Ventilation Europe and Radiators Europe, to tap into their respective market potential more effectively, streamline decision-making processes, and tailor their segment strategies precisely to their needs. The business units North America, Asia, Clean Air Solution, and Heat Exchangers will remain. Going forward, the Light Commercial Ventilation Europe business will be managed independently as well. As part of this reorganization, the Group Executive Committee will be reduced from six to five members. Going forward, it will consist of the CEO, the CFO, and the presidents of the three largest divisions: Residential Ventilation Europe, Radiators Europe, and North America. In this context, Silvia Witschi, who has previously been responsible for Strategy and Digitalization at Zehnder Group, will join the Group Executive Committee effective 1 July 2026. With the implementation of the divisional target organization scheduled for 1 October 2026, Silvia Witschi will assume overall responsibility for Residential Ventilation Europe, and Jörg Metzger for Radiators Europe. With its new, leaner organizational structure, Zehnder Group is laying the groundwork to implement its strategic priorities more consistently and respond more flexibly to market changes. Dorien Terpstra, Chief Commercial Officer (CCO) EMEA and Johannes Bollmann, Chief Operating Officer (COO) Ventilation EMEA, will leave the company after a transition period by the end of 2026 at the latest. The realignment of Zehnder Group’s organizational structure is expected to result in one-off effects of approximately EUR 10 million in the 2026 fiscal year and to yield substantial efficiency gains in the medium term. The medium-term targets of average annual sales growth of around 5% and an EBIT margin before one-off effects of 9–11% are confirmed. Picture: Target organizational chart
