Copenhagen Stock Exchange In September, the Copenhagen Stock Exchange criticized one company for having failed to publish a number of company announcements on the company’s website without undue delay. One company was transferred back from the observation segment to its original position due to the fact that the redemption of remaining shares in another listed company in which the former company held a significant stake had begun. Three companies were transferred to the observation segment in September. One company because it awaits the sale of shareholdings, another because it awaits a mandatory bid on a minority holding, which implied that a third company – the holding company – was also transferred.
