Olezarsen Sodium

Today’s announcement is made in response to the following developments: Group revenue for Q3 2025 reached SEK 7,776 M, up 21 per cent [compared to Q3 2024] at constant exchange rates (CER)[1]. This growth was driven by higher in-market performance of Sobi products, particularly for Altuvoct, Doptelet and Gamifant. The adjusted EBITA margin¹,² for Q3 2025 was 47 per cent, driven primarily by lower-than-anticipated R&D spend, demonstrating disciplined cost control and accelerated effects from organisational changes implemented in Q2 2025. Realigned SG&A and R&D activities following the confirmation from the FDA on a mid-2026 review decision on the NASP biologics license application (BLA) also contributed. Year-to-date revenue as of Q3 2025 was SEK 20,417 M, representing a 15 per cent increase [compared to equivalent year to date 2024] at CER¹, and year-to-date adjusted EBITA margin¹,² as of Q3 2025 was 40 per cent. A revised full year outlook for 2025: Revenue is now anticipated to grow by a low double-digit percentage at CER (previously high-single digit) and adjusted EBITA marginis anticipated to be in the mid-to-high 30s per cent of revenue (previously mid-30s). An impairment charge of SEK 6,612 M is recorded in Q3 2025, relating to the impairment of the product and marketing right for Vonjo. The impairment has not affected cash flow and is included in Items affecting comparability. Vonjo is still projected to be a long-term growth driver. Tryngolza (olezarsen) was approved for familial chylomicronaemia syndrome (FCS) in Europe and positive topline data was announced in severe hypertriglyceridemia (sHTG) in September. Across the major European Union countries—France, Germany, Italy, and Spain—as well as the United Kingdom, it is estimated that approximately 700,000 individuals are affected by multifactorial chylomicronemia syndroms (MCS), a subgroup of sHTG patients. Given the significant number of cases, Sobi believes this condition could offer a market potential exceeding SEK 5 billion within these countries. Sobi plans regulatory filing in MCS in Europe in 2026. Sobi holds the commercial rights to Olezarsen for both FCS and MCS in all countries except in the United States, Canada, and China. Group Outlook 2025 At the publication of the Q4 2024 report on 5 February 2025 Sobi stated the outlook for the FY 2025 to be: Revenue was anticipated to grow by a high single digit percentage at CER and adjusted EBITA margin was anticipated to be in the mid-30s per cent of revenue. Sobi has now upgraded its full-year revenue outlook based on year-to-date performance and accelerated momentum in Q3. Group revenue grew 15 per cent at CER year-to-date and 21 per cent at CER in Q3. This was driven by higher-than-expected in-market performance, particularly for Doptelet and Gamifant, but also other areas contributed. Sobi has also upgraded its adjusted EBITA margin outlook. Adjusted EBITA margin reached 47 per cent in Q3 and 40 per cent year-to-date. The strong performance is driven primarily by lower-than-anticipated R&D spend, demonstrating disciplined cost control and accelerated effects from organisational changes implemented in Q2. Realigned SG&A and R&D activities following the confirmation from the FDA on a mid-2026 review decision on the NASP biologics licence application (BLA) also contribute to the improved outlook. The revised full year 2025 outlook is: Revenue is anticipated to grow by a low double-digit percentage at CER and adjusted EBITA margin is anticipated to be in the mid-to-high 30s per cent of revenue. Impairment of Vonjo Sobi announces today that in accordance with IFRS accounting requirements, it will record a non-cash impairment charge of SEK 6,612 M relating to the impairment of the product and marketing right for Vonjo. At the end of Q3, the carrying amount of Vonjo was SEK 6,263 M. The impairment will be reported as an item affecting comparability. Vonjo is still projected to be a long-term growth driver, following the expected completion of the Pacifica phase 3 study, securing a broader label authorisation in the US and expanding into additional international markets. Efforts are ongoing to accelerate the completion of enrolment in the PACIFICA study, and we continue with the development of potential new indications where there is a high unmet medical need.
