^Ad hoc announcement pursuant to Art. 53 LR Allschwil, Switzerland - May 21, 2024 Idorsia Ltd (SIX: IDIA) today announced its financial results for the first quarter of 2024. Business highlights * Viatris collaboration: Global research and development collaboration, focused on the development and commercialization of two innovative compounds, selatogrel and cenerimod. Commercial highlights * QUVIVIQ(TM) (daridorexant): Total net sales of CHF 10 million in Q1 2024. * QUVIVIQ in the US: Citizens petition to deschedule the DORA class progressing. * QUVIVIQ in Europe: Further launches, including France, provide a solid base to increase European sales in 2024. Pipeline highlights * TRYVIO(TM) (aprocitentan): Approved by the US FDA in March 2024. * JERAYGO(TM) (aprocitentan): Recommended for approval in Europe. * Daridorexant: Phase 3 study conducted by Simcere in Chinese patients fully recruited. Financial highlights * Net revenue Q1 2024 at CHF 10 million. * US GAAP operating expenses Q1 2024 benefiting from extraordinary income from Viatris deal with non-GAAP operating expenses Q1 2024 at CHF 96 million. * US GAAP operating income Q1 2024 of CHF 31 million and non-GAAP operating loss of CHF 85 million. * The Viatris deal: The upfront consideration of USD 350 million (CHF 308 million) was fully paid by Viatris to Idorsia in Q1 2024. * Convertible bond 2024: Bondholders approve an extension of maturity by six months. Guidance for 2024 * QUVIVIQ net sales of around CHF 55 million. * US GAAP operating loss to reach CHF 340 million (which includes a one-off benefit of CHF 125 million from the Viatris deal), non-GAAP operating loss of around CHF 420 million (excluding contract revenues and the one-off benefit from the Viatris deal) - unforeseen events excluded. Jean-Paul Clozel, MD and Chief Executive Officer, commented: "We have already reached significant milestones in 2024. The deal with Viatris to accelerate the development of selatogrel and cenerimod brought cash and security for these assets, while retaining shareholder value. We came to an arrangement with holders of the convertible bond 2024 due for repayment in July, giving us the time we need to secure additional funding and avoid liquidity constraints. Also, the quality of our research and development engine was once again confirmed by the FDA's approval of TRYVIO (aprocitentan) and the CHMP positive opinion received for JERAYGO (the trade name of aprocitentan in Europe). This will now unlock value for Idorsia as we evaluate possible launch strategies - including potential partnership - for the first antihypertensive working on a new pathway seen in almost 40 years." Jean-Paul continued: "Since the first launch of QUVIVIQ, more than 14 million tablets have been dispensed worldwide, with well over 150,000 patients benefiting from QUVIVIQ. We continue to believe in the huge potential offered by this product and - thanks to a long patent life - there is plenty of time for this potential to be realized. Continued innovation is essential to securing the company's future. Despite the reduction of the workforce, we continue to discover and develop new drugs with great potential in many areas of medicine. I am very confident that our vision to create an innovative, profitable, and sustainable science-based company will become a reality in the coming years." Financial results ------------------------------------------------------------------------------- US GAAP results First Quarter ------------------------------------------------------------------------------- in CHF millions, except EPS (CHF) and number of shares (millions) 2024 2023 ------------------------------------------------------------------------------- Net revenues 10 21 ------------------------------------------------------------------------------- Operating expenses 20 (219) ------------------------------------------------------------------------------- Operating income (loss) 31 (198) ------------------------------------------------------------------------------- Net income (loss) 30 (212) ------------------------------------------------------------------------------- Basic EPS 0.17 (1.19) ------------------------------------------------------------------------------- Basic weighted average number of shares 179.1 178.0 ------------------------------------------------------------------------------- Diluted EPS 0.13 (1.19) ------------------------------------------------------------------------------- Diluted weighted average number of shares 233.3 178.0 ------------------------------------------------------------------------------- Net revenue of CHF 10 million in the first quarter of 2024 is the result of QUVIVIQ product sales. This compares to CHF 21 million in the first quarter of 2023, which included CHF 13.5 million sales of PIVLAZ in Japan (now assigned to Nxera Pharma as part of a transaction, more details can be found in the dedicated press release (https://www.idorsia.com/investors/news-and- events/media-releases/media-release-details?id=3041539)) and CHF 1 million revenue share from Johnson & Johnson related to ponesimod sales (revenue-sharing agreement now eliminated as part of the reacquisition of aprocitentan, more details can be found in the dedicated press release (https://www.idorsia.com/investors/news-and-events/media-releases/media-release- details?id=3073952)). US GAAP operating expenses in the first quarter of 2024 benefitted from extraordinary income of CHF 125 million from the Viatris deal resulting in a negative expense of CHF 20 million (CHF 219 million in the first quarter of 2023), of which CHF 4 million related to cost of sales (CHF 1 million in the first quarter of 2023), CHF 33 million to R&D expenses (CHF 93 million in the first quarter of 2023), and CHF 68 million to SG&A expenses (CHF 125 million in the first quarter of 2023). US GAAP net income in the first quarter of 2024 amounted to CHF 30 million (CHF 212 million net loss in the first quarter of 2023). The decrease of the net loss is mainly attributable to the one-off income related to the Viatris Deal but was also driven by lower operating expenses throughout all functions. The US GAAP net income resulted in a basic net income per share of CHF 0.17 (diluted net income per share of CHF 0.13) in the first quarter of 2024, compared to a net loss per share of CHF 1.19 (basic and diluted) in the first quarter of 2023. ------------------------------------------------------------------------------- Non-GAAP* measures First Quarter ------------------------------------------------------------------------------- in CHF millions, except EPS (CHF) and number of shares (millions) 2024 2023 ------------------------------------------------------------------------------- Net revenues 10 21 ------------------------------------------------------------------------------- Operating expenses (96) (202) ------------------------------------------------------------------------------- Operating income (loss) (85) (181) ------------------------------------------------------------------------------- Net income (loss) (86) (189) ------------------------------------------------------------------------------- Basic EPS (0.48) (1.06) ------------------------------------------------------------------------------- Basic weighted average number of shares 179.1 178.0 ------------------------------------------------------------------------------- Diluted EPS (0.48) (1.06) ------------------------------------------------------------------------------- Diluted weighted average number of shares 179.1 178.0 ------------------------------------------------------------------------------- * Idorsia measures, reports, and issues guidance on non-GAAP operating performance. Idorsia believes that these non-GAAP financial measurements more accurately reflect the underlying business performance and therefore provide useful supplementary information to investors. These non-GAAP measures are reported in addition to, not as a substitute for, US GAAP financial performance. Non-GAAP net loss in the first quarter of 2024 amounted to CHF 86 million: the CHF 116 million difference versus US GAAP net income was mainly due to the one- off effect of the Viatris Deal (CHF 125 million income), depreciation and amortization (CHF 4 million), and share-based compensation (CHF 4 million). The non-GAAP net loss resulted in a net loss per share of CHF 0.48 (basic and diluted) in the first quarter of 2024, compared to a net loss per share of CHF 1.06 (basic and diluted) in the first quarter of 2023. Viatris collaboration In March 2024, Idorsia closed agreements with Viatris Inc. (NASDAQ: VTRS), a global healthcare company, for collaboration on the global development and commercialization of two Phase 3 assets - selatogrel and cenerimod - with Idorsia receiving an upfront payment of USD 350 million, and the right to potential development and regulatory milestone payments of up to USD 300 million, potential sales milestone payments of up to USD 2.1 billion, and potential contingent tiered royalties from mid-single- to low-double-digit percentage on annual net sales. A joint development committee is overseeing the development of the ongoing Phase 3 programs for selatogrel and cenerimod up to regulatory approval. Idorsia will contribute up to USD 200 million in the next 3 years and transferred the dedicated personnel for both programs to Viatris. Viatris has worldwide commercialization rights for both selatogrel and cenerimod (excluding, for cenerimod only, Japan, South Korea, and certain countries in the Asia-Pacific region). Idorsia has also granted Viatris a right of first refusal and first negotiation for certain other pipeline assets. Convertible bonds 2024 In July 2018, the Group issued CHF 200 million of senior unsecured convertible bonds (ISIN: CH0426820350), which were due to mature on July 17, 2024. On May 6, 2024, a bondholder meeting was held, where 83.5% of the total outstanding bondholders voted in favor of amendments to the terms of the bonds. The approved bond terms include an amended conversion price of CHF 6.00, extended maturity date of January 17, 2025, and the option to call the bonds at par, in full or in part, at any time upon giving ten trading days' notice. The company has applied to the higher cantonal composition authority and upon approval the amendments to the bond terms will become binding and effective. A consent fee of 8,000,000 Idorsia shares will be delivered through SIX SIS once the amendment of the bond terms is effective. Financial outlook 2024 For 2024 - excluding unforeseen events - the company expects QUVIVIQ net sales of around CHF 55 million; SG&A expenses of around CHF 300 million; R&D expense of around CHF 165 million for Idorsia-led pipeline assets; non-GAAP operating expenses of up to CHF 470 million. This performance would result in a non-GAAP operating loss of around CHF 420 million (excluding contract revenues and the one-off benefit from the Viatris deal). The company expects US GAAP operating loss for 2024 to reach CHF 340 million which includes a one-off benefit of CHF 125 million from the Viatris deal. André C. Muller, Chief Financial Officer, commented: "In addition to the funds already raised from our business development activities, I am confident in our ability to raise additional funding this year. We will continue to evaluate and prepare possible launch strategies - including potential partnership - for TRYVIO. The significant progress with access and availability of QUVIVIQ has started to gain traction, particularly in Europe, this will translate into higher sales in 2024. At the same time, the cost reduction initiative that took place in the latter part of 2023 is fully effective and reflected in our 2024 guidance, with significantly lower expenses. We must continue to control our costs and explore all avenues to extend our cash runway, but I see many reasons to be optimistic for the future of Idorsia." Liquidity and indebtedness At the end of the first quarter of 2024, Idorsia's liquidity amounted to CHF 335 million. ---------------------------------------------------------------- (in CHF millions) March 31, 2024 Dec 31, 2023 ---------------------------------------------------------------- Liquidity ---------------------------------------------------------------- Cash and cash equivalents 335 145 ---------------------------------------------------------------- Short-term deposits - - ---------------------------------------------------------------- Total liquidity* 335 145 ---------------------------------------------------------------- ---------------------------------------------------------------- Indebtedness ---------------------------------------------------------------- Convertible loan 335 335 ---------------------------------------------------------------- Convertible bond 797 796 ---------------------------------------------------------------- Other financial debt 162 162 ---------------------------------------------------------------- Total indebtedness 1,293 1,293 ---------------------------------------------------------------- *rounding differences may occur Commercial operations In the first quarter of 2024, QUVIVIQ(TM) (daridorexant) in the US, Germany, Italy, Switzerland, Spain, UK, Canada, Austria, and France generated total product sales of CHF 10 million. United States ------------------------------------------------------------------------------- Product Mechanism of action Indication Commercially available since ------------------------------------------------------------------------------- Dual orexin receptor Treatment of adult May 2022 antagonist patients with insomnia, characterized by difficulties with sleep onset and/or sleep maintenance ------------------------------------------------------------------------------- In the US, net sales of QUVIVIQ(®) (daridorexant) in the first quarter of 2024 reached CHF 6.5 million. This net sales number includes the QUVIVIQ copay program aimed at driving demand and product uptake, and thus does not reflect the actual number of prescriptions dispensed. As of the end of the first quarter of 2024, more than 140,000 patients have been treated with QUVIVIQ, almost 400,000 prescriptions have been dispensed, and the product has been prescribed by more than 42,000 healthcare professionals. To begin with, the company ran a direct-to-consumer (DTC) television and digital campaign and offered a copay program. The strategy was to create a recognizable brand, enabling market access discussions. During 2023, the company made significant progress, reaching over 65% reimbursement in the commercial sector. As access increased, the commercial approach was adjusted, with the aim being to switch from a consignment model (providing substantially reduced or free prescriptions) to a payer paid model. In the first quarter of 2024, paid prescriptions accounted for 68% of the total - an increase of 36 percentage points from the same period in 2023 and of 7 percentage points from the previous quarter. The first Medicare Part D coverage - reaching 27% of covered lives - began in January 2024, opening an entirely new channel which has the potential to substantially improve product access and paid prescriptions. In February, there was a cyberattack on Change Healthcare (UnitedHealth Group), the largest adjudicator/processor of copay cards in the US, causing major disruption across the pharmaceutical industry, including the QUVIVIQ copay cards, with a negative impact on prescription dispensing levels. In March, the Idorsia US Market Access team put a solution in place to remedy the disruption, though the impact was still appreciable through to the end of March. In April 2023, Idorsia filed a citizen petition (CP), urging the Drug Enforcement Administration (DEA) to deschedule the DORA class of chronic insomnia medications, based on a review of evidence from available data, including post-marketing surveillance data. Starting in 2015, the independent FDA approvals of other DORAs included a recommendation that these drug products be scheduled based on preclinical data. The CP to deschedule the DORA class outlines current scientific and medical evidence demonstrating that the DORA class has a negligible abuse profile and potential for abuse, lacks non-medical use in the community, lacks physical and psychological dependence, and therefore, should not be a scheduled class under the Controlled Substances Act. The DEA and FDA acknowledged the CP, and the process to analyze and examine the request is moving forward. Notably, a report accompanying the FDA appropriations bill that was finalized in March 2024 informed the FDA that the process for descheduling the DORA class is a priority for Congress. Tausif 'Tosh' Butt, President, and General Manager of Idorsia US, commented: "I believe one of the biggest barriers to prescribing QUVIVIQ is the fact it is currently a scheduled drug. Apart from the obstacles to prescribing scheduled drugs, some payers require patients to be treated with low-cost drugs not indicated for insomnia, and others that carry black box warnings before covering QUVIVIQ. The US Congress has long supported the efforts of the FDA to address the opioid and addiction crisis, and this year it encouraged the FDA to also consider the impact of treatments for insomnia as a part of that larger public health mission. I am very hopeful for our citizen petition requesting a review of the evidence can lead to the descheduling of the DORA class of chronic insomnia medications."

Lowering blood pressure reduces the risk of fatal and non-fatal cardiovascular events, primarily strokes and myocardial infarctions. The recommended dosage of TRYVIO is 12.5 mg orally once daily, with or without food. Idorsia plans to make TRYVIO available in the second half of 2024 to the millions of patients in the US whose high blood pressure is not adequately controlled by other drugs. Further details on the approval, together with commentary from company management can be found in the dedicated press release (https://www.idorsia.com/investors/news-and-events/media-releases/media-release- details?id=3195250) and investor webcast (https://www.idorsia.com/investors/news-and-events/investor- webcasts/aprocitentan-approval-webcast) available from the company corporate website.

Europe and Canada ------------------------------------------------------------------------------- Product Mechanism of action Indication Commercially available ------------------------------------------------------------------------------- Dual orexin receptor Treatment of adult France: Mar. 2024 antagonist patients with insomnia characterised by Austria: Feb. 2024 symptoms present for at least three months and UK: Oct. 2023 considerable impact on daytime functioning Spain: Sep. 2023 Switzerland: Jun. 2023 Germany: Nov. 2022 Italy: Nov. 2022 ------------------------------------------------------------------------------- Management of adult Canada: Nov. 2023 patients with insomnia, characterized by difficulties with sleep onset and/or sleep maintenance ------------------------------------------------------------------------------- QUVIVIQ (daridorexant) net sales in the first quarter of 2024 reached CHF 3.5 million in the EUCAN region. In November 2023, treatment with daridorexant was added to the insomnia treatment guidelines for Europe. In "The European Insomnia Guideline: An update on the diagnosis and treatment of insomnia 2023", published in the Journal of Sleep Research, the authors note that "The introduction of DORAs has probably been the most significant recent development in the pharmacological treatment of insomnia." In Germany, QUVIVIQ was launched in November 2022. By law, sleep medications were then subject to a 4-week prescribing limitation (Anlage III BtMG). Following a review by the Federal Joint Committee (G-BA) - the highest decision- making body of the joint self-government of physicians, dentists, hospitals, and health insurance funds in Germany - this limitation was lifted for QUVIVIQ in November 2023. This makes it the only sleep medication in Germany that can be prescribed for long-term treatment of chronic insomnia. In December 2023, the price negotiated for QUVIVIQ under the AMNOG process became effective. Following the lifting of the prescribing limitation, the company submitted a second AMNOG dossier for the long-term treatment of chronic insomnia disorder (beyond 4 weeks), reflecting the indication approved by the EMA in 2022. The progress made in Germany is reflected by the performance of QUVIVIQ on the market, with a 63% increase in demand seen in Q4 2023 (compared to Q3 2023), followed by a strong start to 2024 (February +41% compared to December 2023). In Italy, QUVIVIQ was launched in November 2022. Currently, QUVIVIQ can only be prescribed by neurologists, psychiatrists, and specialists from sleep centers, and no sleep therapy is reimbursed. The company submitted a reimbursement dossier in June 2023 and requested the expansion of the prescriber base. The submission - detailing the efficacy and safety profile of QUVIVIQ and its estimated budget impact and cost-effectiveness in Italy - is under review, with the final outcome expected in the second half of 2024. In Switzerland, QUVIVIQ was launched to the self-pay market in June 2023. Following the launch of QUVIVIQ, awareness has increased among all specialties, and demand has increased solidly (+32% in Q4 2023 compared to Q3 2023) ahead of reimbursement, which is expected in the summer of 2024. In Spain, QUVIVIQ was launched to the self-pay market in September 2023. Spain represents the largest insomnia market in Europe, as was apparent in the first months of this product's availability, despite it only being launched to the self-pay market. The company is assessing the opportunity to submit a reimbursement dossier to the Spanish authorities, in order to allow equal access for all patients with chronic insomnia. In the UK, QUVIVIQ was launched in October 2023. At the same time, technology appraisal guidance was published by the National Institute for Health and Care Excellence (NICE), allowing the transition to local access discussions and listing by healthcare boards for England, Wales, and Northern Ireland. In April 2024, the Scottish Medicines Consortium (SMC) also accepted QUVIVIQ for use within NHS Scotland. This means that the company has achieved full reimbursement throughout the UK, where QUVIVIQ is now recommended as first-line pharmaceutical treatment for patients with chronic insomnia, after, or as an alternative to, cognitive behavioral therapy for insomnia (CBT-I). The priority in the UK now, is to secure regional access. In France, QUVIVIQ was launched in March 2024 as the first and only pharmacotherapy recommended for the treatment of chronic insomnia disorder. In January 2024, the inclusion of QUVIVIQ in both the hospital and the retail formulary list of reimbursed pharmaceutical specialties was announced in the French Official Gazette, together with the French public price. This official publication means that, with a prescription from their doctor, patients with chronic insomnia in France have access to the treatment if they meet the requirements of the EU prescribing label for QUVIVIQ. The publication follows the positive recommendation by the Transparency Committee in May 2023, recognizing QUVIVIQ as providing clinical added value. In Canada, after being approved in April 2023, QUVIVIQ was launched in November 2023 to the private market, representing 55% of the Canadian insomnia market. The reimbursement dossier was submitted to private market payers in the third quarter of 2023, and just a few months after the submission the team had secured reimbursement for more than 60% of private market patients. The focus is now on public payers with the submission to INESSS (Institut national d'excellence en santé et en services sociaux) finalized in March 2024 and the submission to CADTH (Canada's Drug and Health Technology Agency) expected in the second quarter of 2024. Jean-Yves Chatelan, President of Europe and Canada region, commented: "The launch of Europe's first and only dual orexin receptor antagonist is progressing well across all markets where we have made QUVIVIQ available. Including Canada, we have expanded availability into more markets and improved the reimbursement environment beyond many expectations. With continued positive feedback from physicians and patients on the differentiated profile of QUVIVIQ, I am very optimistic that the progress we have made will now translate into many more patients benefiting from QUVIVIQ and increasing volumes advancing the region towards profitability."

Research & Development Idorsia has a diversified and balanced portfolio, comprising assets developed and/or marketed by Idorsia and assets that are partner-led to maximize the value we have created. Our drug discovery engine has produced innovative drugs with the potential to transform the treatment paradigm in multiple therapeutic areas, including CNS, cardiovascular, and immunological disorders, as well as orphan diseases. The company also has a vaccine platform for the discovery and development of glycoconjugate vaccines containing synthetic antigenic glycan molecules, with or without a carrier protein, to prevent infection. Alberto Gimona, MD and Head of Global Clinical Development of Idorsia, commented: "Despite a difficult period for our organization, the team has shown extraordinary commitment and made great progress with our portfolio. This is particularly evident in the successful registration of aprocitentan in the US and the positive opinion from the European Union's CHMP, with labels that reflect the value of the compound. I was also very pleased to have found a way for both selatogrel and cenerimod programs to be fully supported through the collaboration with Viatris, while maintaining our involvement in their development. I look forward to advancing the portfolio and bringing benefits to patients in many areas of medical need."

Rather than inducing sleep through broad inhibition of brain activity, daridorexant only blocks the activation of orexin receptors. Daridorexant is commercially available as QUVIVIQ in the US, Germany, Italy, Switzerland, Spain, the UK, Canada, Austria, and France, and is approved throughout the EU (see "Commercial operations" above). A post-approval study to investigate the efficacy of daridorexant in patients with insomnia and comorbid nocturia has completed recruitment and is expected to report results in mid-2024 (NCT05597020). Idorsia has initiated a Phase 2 dose-finding study to assess the efficacy, safety, and pharmacokinetics of multiple-dose oral administration of daridorexant in pediatric patients aged 10 to °
