SIX Exchange Regulation: Investigation Of Lonza Group AG

Date 16/07/2009

SIX Exchange Regulation initiates investigation of Lonza Group AG for potential violation of the rules governing management transactions, reporting obligations and ad hoc publicity.

SIX Exchange Regulation, a SIX Swiss Exchange AG body charged with the supervision and enforcement of issuer obligations, has initiated an investigation of Lonza Group AG in response to the suspicion that Lonza Group AG may have breached its obligations regarding reporting obligations, ad hoc publicity and the disclosure of management transactions. The investigation is being conducted in connection with the delayed reporting of transactions made by a member of senior management (disclosure of management transactions) as well as the circumstances of the publication of changes in the composition of the company’s board of directors (Ad hoc publicity). Also under investigation is Lonza’s failure to provide SIX Exchange Regulation with a copy of the invitation to and agenda of its annual general meeting of shareholders (reporting obligations). Investigatory proceedings will continue for an indefinite period. SIX Exchange Regulation will announce its findings, although no information will be provided while the proceedings are ongoing.
