    shares of Idorsia

Allschwil, Switzerland - April 11, 2024
Idorsia Ltd (SIX: IDIA) today announced that the company intends to call a
bondholder meeting for holders of its outstanding convertible bond maturing on
July 17, 2024 (ISIN: CH0426820350). The company will propose a change to the
current Terms and Conditions to be voted upon by bondholders.
Over the course of the past days, Idorsia has reached out to several of the
bondholders and received positive feedback on the amenability to adopting
additional Terms and Conditions: the proposed change to the Terms and Conditions
would give Idorsia the right at maturity, at its option, to repay the Bonds
fully or partially in shares of Idorsia. Any amount not repaid in shares would
be repaid in cash.
Idorsia's main investors, Jean-Paul and Martine Clozel, are fully committed to
Idorsia over the long-term and as such commit to participating in adopting
amended Terms and Conditions. Furthermore, Jean-Paul and Martine Clozel have
agreed to a 180-day lock-up period post maturity in the event that the
convertible bond will be repaid in shares, subject to customary exceptions.
For a full or partial settlement in shares, Idorsia would need to give notice on
the elected settlement alternative no later than 30 calendar days prior to the
maturity date. The reference price used to calculate the number of shares to be
delivered in case of a redemption in shares will be set as 95% of the average
daily volume-weighted average price (VWAP) of one share in the 20 consecutive
Trading Days commencing on (and including) the 20th Trading Day before the
Maturity Date, or if later, the Effective Date. Holders of the bonds who are
Institutional Investors will have the option to receive shares or opt for an
organized share sale which will be conducted by way of a private placement of
shares on or about the Maturity Date. Idorsia intends to include a provision in
the proposed amendment of the Terms and Conditions to provide bondholders
participating in such placement with some protection against potential downside
in connection with such placement. Up to CHF 10 million could be used by the
company to limit potential downside in a share placement.
Idorsia has appointed J.P. Morgan Securities plc to act as Dealer Manager for
the bondholder solicitation process.
The financial status as of March 31, 2024, is required in connection with the
bondholder meeting. Idorsia therefore intends to publish on April 17, 2024, the
formal invitation to the bondholder meeting concurrently with announcing its
unaudited financial status as of March 31, 2024. The bondholder meeting is
expected to take place on April 30, 2024.
Idorsia will further postpone the publication of its audited Full-Year 2023
Financial Results as well as the Q1 2024 Financial Results from the currently
scheduled April 25, 2024, to May 21, 2024. On April 8, 2024, the SIX Exchange
Regulation (SER) granted Idorsia a request for extension of the 2023 publication
and submission of the Annual Report until May 31, 2024. The rationale for this
request is related to the contemplated amendment of the convertible bond
maturing on July 17, 2024 (ISIN: CH0426820350) as announced today.
As required by SIX Exchange Regulation (SER), Idorsia hereby reprints paragraph
I of the SER's decision: Idorsia's request is granted as follows:
 I. The exemption request of Idorsia (Issuer) dated 03 April 2024 regarding an
    extension of the deadline to publish its 2023 annual report and to file such
    report with SIX Exchange Regulation AG until 31 May 2024 at the latest is
    granted with the following reservation (lit. a) and under the following
    conditions (lit. b):
     a. SIX Exchange Regulation AG reserves the right to suspend trading of the
        registered shares of the Issuer in case its 2023 annual report is not
        published in accordance with the provisions on ad hoc publicity (Art.
        53 of the Listing Rules (Listing Rules dated 23 August 2023 )[LR] in
        connection with the Directive on Ad hoc Publicity [DAH]) and not filed
        with SIX Exchange Regulation AG until Friday, 31 May 2024, 11.59 pm CET,
        at the latest.
     b. Idorsia is required to publish a notice in accordance with the
        provisions on ad hoc publicity (Art. 53 LR in connection with the DAH)
        concerning this decision until Tuesday, 30 April 2024, 7.30 am CET, at
        the latest.
            The notice must contain:
  * the unaltered reproduction of the wording of para. I. of this decision,
    placed in a prominent position;
  * the reasons for the application of the Issuer requesting an extension of the
    deadline to publish its 2023 annual report and to file such report with SIX
    Exchange Regulation AG (SER).
