As of today, Actelion's new Board members Ludo Ooms (Chairman), Julian Bertschinger, Claudio Cescato, Pascal Hoorn and Andrea Ostinelli, who were elected at the Annual General Meeting of Actelion's shareholders on 5 April 2017 (AGM 2017) with effect from the date of completion of the public tender offer, assume their office. All incumbent members of Actelion's Board (Jean-Pierre Garnier, Jean-Paul Clozel, Juhani Anttila, Robert J. Bertolini, John J. Greisch, Peter Gruss, Michael Jacobi, Jean Malo, David Stout and Herna Verhagen) had only been elected at the AGM 2017 for a term of office until the date of completion of the public tender offer and will, thus, leave Actelion as of today. Immediately following the completion of the public tender offer, Actelion will file petitions with SIX Swiss Exchange for the de-listing of the Actelion shares from SIX Swiss Exchange and for exemptions from certain disclosure obligations under the Listing Rules of SIX Swiss Exchange until the date of de-listing of the Actelion shares.
