Events that could affect the price of a share beyond the usual fluctuations must be communicated immediately and clearly by listed companies. This brings all interested market participants to the same level of information.
WHAT NEEDS TO BE PUBLISHED
The ad hoc publicity obligation covers price-sensitive facts, if applicable such as financial figures, staff changes and planned mergers. There is no exhaustive list of events so the decision as to whether to publish an ad hoc announcement is at the discretion of the listed company. An exception thereto are annual and interim reports pursuant to Art. 49 and Art. 50 LR, which must always be published with an ad hoc announcement pursuant to Art. 53 LR.
WHEN IT NEEDS TO BE PUBLISHED
An ad hoc announcement is required as soon as the company becomes aware of the essential elements of the matter at hand. If possible, the announcement must be published outside of critical trading hours: before 7:30 am or after the close of trading at 5:40 pm. If, in exceptional cases, the announcement is made during critical trading hours, we must be informed at least 90 minutes before publication so that we can temporarily cease trading of the affected securities if the situation requires it.
WHERE IT NEEDS TO BE PUBLISHED
To reach the widest audience, ad hoc announcements must be sent not only to us, but also to at least two electronic financial news services and two Swiss media (printed or electronic). The announcement must also appear on the listed company’s website and must be sent to interested market participants by email.
