Corporate Governance

1. Group structure and shareholders

1.1 Group structure

Zehnder Group follows a differentiated structure. From an EMEA perspective, it is organised into the two segments, ventilation and radiators, whereas the divisions Clean Air Solutions and CORE are organised separately. Eventually, the two divisions of North America and China are organised by country region. While the Managing Directors and Chief Officers report directly to the CEO, the Group functions report either to the CEO or the CFO.

Zehnder Group AG, the holding company of Zehnder Group, is the only listed company included in the consolidation scope. It is headquartered in Gränichen (CH). The registered shares A are listed on the SIX Swiss Exchange (number: 27 653 461, ISIN: CH0276534614). The unlisted registered shares B (nominal value CHF 0.01) are held by Graneco AG, which is controlled by the Zehnder families. As of 31 December 2025, the market capitalisation (registered shares A) was CHF 758.1 million and the total capitalisation was CHF 920.1 million.
