Allschwil, Switzerland – May 21, 2024
Idorsia Ltd (SIX: IDIA) today announced changes to the Idorsia Executive Committee (IEC) and will propose changes in membership of the Board of Directors at the upcoming Annual General Meeting of shareholders (AGM), to be held on June 13, 2024.

Jean-Paul Clozel, 69, has decided to retire from his role as Chief Executive Officer (CEO) of Idorsia and stand for election as Chairman of the Board of Directors at this year’s AGM. Jean-Paul has served as CEO of Idorsia since its foundation – the result of demerging the drug discovery and early clinical pipeline of Actelion, as part of the USD 30 billion acquisition. Jean-Paul had previously co-founded Actelion in 1997 and went on to lead the company as CEO in 2000 when the company became publicly traded.

Jean-Paul Clozel, MD and CEO of Idorsia, commented:
"It has been an absolute privilege to serve as CEO of Actelion and Idorsia for the past 24 years. I can think of no greater endeavor than discovering new medicines that help patients lead better lives. I’ve been very fortunate to work alongside some amazing people from all disciplines and together, we have achieved more than I could have ever imagined when I started out in my research career. The time is right for me to retire from the day-to-day running of Idorsia and hand the reins over to a younger generation to lead the company through the next phase of growth. Having devoted so much energy to Idorsia, I want to stay engaged and support the company to realize its potential, hence me standing for election as Chairman. I’m confident that Mathieu and I will form a strong partnership in leading the Board. I will also be able to devote more time to science which has always been my passion.”

From June 13, 2024, André C. Muller will take on the position of CEO. André has served as the Chief Financial Officer (CFO) of Idorsia since its foundation and has taken the lead in the company’s Business Development initiatives in recent years. Before establishing Idorsia, André served as CFO of Actelion from 2013, leading the company through its acquisition and playing a crucial role in the demerger process.

Jean-Paul Clozel, commented:
"André has played a critical role in advancing Idorsia, particularly regarding our fund-raising and business development activities. He has shown the perfect qualities of a biotech leader; creativity, solution-oriented, resilient, a team-player and pragmatic – all qualities that we need to successfully discover and develop innovative drugs. Having worked with André for more than 10 years, I have observed that, despite not being a scientist by training, he has a keen understanding of innovative drug discovery and development. I have absolute confidence that he is the right person to prepare the company for an exciting future.”

As a result of André becoming CEO, the role of CFO will remain an IEC member and be taken by Arno Groenewoud, the current Head of Finance and Procurement. In addition, Julien Gander, Group General Counsel, will become a member of the IEC.

André C. Muller, Chief Financial Officer, commented:
"I am very honored that the Board, its current Chairman, Mathieu Simon, and Jean-Paul have put this trust in me, particularly following such a long and successful tenure for Jean-Paul as CEO. I look forward to the challenge of delivering on the high expectations we have for Idorsia and will work closely with all colleagues around the globe who never fail to impress with their commitment and expertise. I welcome Arno and Julien to the executive team. Having worked closely with both Arno and Julien, I am convinced that their skills and strategic thinking will be vital as the company moves towards financial sustainability while managing multiple partnerships.”

As of June 13, 2024, the IEC will consist of 5 members: André Muller, CEO; Martine Clozel, Chief Scientific Officer; Alberto Gimona, Head of Global Clinical Development; Arno Groenewoud, CFO; and Julien Gander, Group General Counsel.

At this year’s Annual General Meeting, the Board will propose a reduced number of Board members for the time being. Three of the current Board members – Jörn Aldag, Felix Ehrat, Peter Kellogg – will not stand for re-election, with only one new member, Bart Filius, being proposed to the Board. The following Board members will stand for re-election: Jean-Paul Clozel (proposed Chairman), Mathieu Simon (Vice-Chairman and Lead Independent Director), Srishti Gupta, Sophie Kornowski, and Sandy Mahatme.

Mathieu Simon, Chairman of the Board of Idorsia commented:
"This year, the Board has held numerous additional meetings to discuss and review the various strategic initiatives. I’m very grateful for each member contributing generously with their expertise and experience. To those not standing for re-election, I say thank you for serving the company with professionalism and dedication. Bart’s very extensive financing, business development, and commercial experience in the biotechnology and pharmaceutical industry would be invaluable to Idorsia. I am completely behind the new management team, and proposing Jean-Paul to the Chairmanship, and I look forward to serving as Vice-Chairman and Lead Independent Director with the other members of the Board focused on guiding Idorsia as we execute our strategy.”

Following a competitive selection process, the company considers it appropriate to invite a fresh perspective by proposing the election of Deloitte AG, Basel as a new statutory auditor.
