Ad hoc publicity

The Listing Rules of the SIX Swiss Exchange regulate the obligations that companies listed on the SIX Swiss Exchange must fulfil in order to retain their listing. Their aim is to create transparency for investors with regard to potentially price-sensitive information, one method being ad hoc publicity.

Examples of price-sensitive information are:
  • publication of financial results
  • mergers or takeovers
  • spin-offs
  • restructuring
  • capital changes
  • takeover offers
  • significant changes in profit (e.g. drops in profit or profit warning) and
  • financial reorganisations.

Any information that could have a substantial influence on the share price generally falls under the rules governing ad hoc publicity. As the list of information subject to ad hoc publicity disclosure is not exhaustive, it is up to the company in question to determine what falls into this category.
