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.

About Jean-Paul Clozel

Jean-Paul Clozel, 69, is a cardiologist educated in France. He furthered his

training in pharmacology and physiology at the University of Montreal, Canada,

University of California, and San Francisco. After eleven years as a clinician,

he decided to move to applied research and joined the Roche Cardiovascular Drug

Discovery group. During his 12 years at F. Hoffmann-La Roche Ltd, Jean-Paul was

responsible for the selection of the first calcium T-channel blocker and

contributed to several key research programs, such as the selection of the first

orally active renin inhibitor and the characterization of several anti-

thrombotic agents.

During his 25-year-career in cardiovascular research, Jean-Paul has published

widely in peer-reviewed medical and scientific journals. At the same time, his

passion has remained unchanged: being involved as closely as possible in

bringing innovative medicine to "his" patients. He has developed various novel

experimental models allowing for the differentiation of these drugs, work

honored with the 1997 Hoffmann-La Roche Research Prize. In 2007, he was

nominated for a professorship at the Collège de France in Paris, France (Chair

At the end of 1997, Jean-Paul co-founded Actelion to continue his work in

cardiovascular research and development. In April 2000, he assumed the role of

CEO when Actelion became a publicly traded company and subsequently launched

three blockbuster drugs.

With the acquisition of Actelion by Johnson & Johnson in June 2017, Jean-Paul

co-founded Idorsia, a new biopharmaceutical company that was established by

demerging the drug discovery and early clinical pipeline business from Actelion.

Idorsia is specialized in the discovery and development of small molecules to

provide innovative medicines in areas of unmet patient need.

In the first 7 years of Idorsia's existence, the company launched two innovative

drugs, one for the treatment of insomnia disorder and one for the prevention of

cerebral vasospasm following subarachnoid hemorrhage, with a third medicine on

the verge of being launch for the treatment of uncontrolled blood pressure.

Idorsia continues to perform innovative research across multiple therapeutic

areas to feed its broad and diversified drug development pipeline.

As a result of the establishment of Actelion and Idorsia, several hundred new

jobs have been created in Switzerland as well as in other European countries,

the US and Japan.
