10. Sonstige Kommentare:

grosso tec AG (HRB 11558 – AG München) is a shareholder of Kontron AG. grosso holding gesellschaft mbH (FN 559732 k) and Hannes Niederhauser each hold 47.5% of the share capital of grosso tec AG, so that grosso holding gesellschaft mbH and Hannes Niederhauser have so far been controlling grosso tec AG jointly. Hannes Niederhauser has now relinquished joint-control of grosso tec AG. The shareholding held by grosso tec AG in Kontron AG is therefore no longer attributable to Hannes Niederhauser. Neither grosso tec AG nor DI Hannes Niederhauser have sold Kontron shares.

The shareholding of Hannes Niederhauser in Kontron AG has thus mathematically fallen below the 4% threshold and also the 3% threshold.
