We have advanced multiple pipeline programs and further strengthened our innovation engine through targeted business development, including the acquisition of Imcheck Therapeutics. We also achieved promising proof-of-concept for IPN10200, our first-in-class differentiated long-acting recombinant molecule. We are expecting another year of double-digit sales growth for 2026, supported by accelerated performance across the entire portfolio and a better outlook for Somatuline given the production challenges faced by generic competition. We anticipate five regulatory and clinical milestones this year and to further deliver on our external innovation strategy.” Full-year 2026 guidance and mid-term outlook Ipsen has set for FY 2026 the following financial guidance: Total sales growth greater than 13.0%, at constant currency. Based on the average level of exchange rates in January 2026, an adverse effect on total sales of around 2% of currencies is expected Core operating margin greater than 35.0% of total sales, which includes additional R&D expenses from anticipated early and mid-stage external-innovation opportunities Guidance on total sales and core operating margin is assuming accelerated sales growth of the portfolio excluding Somatuline and the growth of Somatuline sales due to generic lanreotide challenges. It excludes any impact from potential late-stage (Phase III clinical development or later) business development transactions. As part of its ongoing review of long-term assumptions including competitive intensity and product lifecycle considerations, Ipsen no longer expects to achieve the €500m peak sales for Onivyde and Tazverik. Based on higher expected Somatuline sales due to continued generic lanreotide production challenges and the performance of the broader portfolio, Ipsen is highly confident on its 2027 mid-term outlook to exceed the total-sales average growth 5 of at least 7% per year for the period 2023-27 and core operating margin in 2027 of at least 32% 6 of total sales. Pipeline progress During 2025, Ipsen achieved a number of important regulatory and clinical milestones across its portfolio, reflecting continued advancement of its pipeline across the three therapeutic areas. In the first quarter of 2025, the regulatory filing for tovorafenib, an oral, type II RAF-kinase inhibitor for pediatric low-grade glioma, was accepted for review by the European Medicines Agency (EMA). In May 2025, Ipsen presented Phase II data from the ELMWOOD study of Iqirvo® (elafibranor) at the European Association for the Study of the Liver (EASL) Congress, demonstrating a favorable safety pro dose-dependent efficacy over 12 weeks in people living with primary sclerosing cholangitis, a condition with high unmet medical need. In July 2025, the European Commission approved Cabometyx® (cabozantinib) for the treatment of previously treated advanced neuroendocrine tumors (NETs), based on positive results from the Phase III CABINET trial. In September 2025, positive Phase II data from the LANTIC trial in aesthetics were reported, demonstrating a differentiated, long-acting clinical pro IPN10200. During the year, Ipsen also initiated a Phase II study of IPN10200 in cervical dystonia, representing the fourth clinical study in the development plan of the global long-acting recombinant molecule across therapeutic and aesthetic indications. In December 2025, Ipsen announced that the pivotal Phase II FALKON trial of fidrisertib in fibrodysplasia ossificans progressiva (FOP) did not meet its primary endpoint and that the study was subsequently closed; fidrisertib was generally well-tolerated, with no safety concerns identified. In addition, Ipsen initiated multiple Phase I oncology studies across IPN01195, a RAF inhibitor, the antibody-drug conjugate IPN60300 and the T-cell activator IPN01203, further strengthening its targeted oncology pipeline. External innovation In December 2025, Ipsen expanded its immuno-oncology portfolio with the acquisition of ImCheck Therapeutics, a biotechnology company developing next-generation immuno-oncology therapies including IPN60340 (ICT01), a first-in-class monoclonal antibody targeting BTN3A, currently in Phase I/II development, with a Phase IIb/III study planned to start in 2026. IPN60340 has the potential to be a new standard of care in combination in first line unfit acute myeloid leukemia, an aggressive blood cancer affecting older adults. Interim data orally presented at the annual American Society of Clinical Oncology 2025 from the Phase I/II EVICTION trial showed treatment with ICT01 in combination with venetoclax and azacitidine (Ven-Aza) achieved very encouraging high responses. In this single-arm trial, treatment response nearly doubled relative to those seen in historical standard-of-care data across all molecular subtypes in newly diagnosed patients including sub-types typically less responsive to standard-of-care (Ven-Aza). In January 2026, Ipsen also announced that IPN60340 received U.S. FDA Breakthrough Therapy Designation in first-line unfit acute myeloid leukemia. In December 2025, Ipsen further strengthened its oncology and early-stage pipeline through two additional targeted business development and research collaborations. Ipsen entered into an exclusive licensing agreement with Simcere Zaiming for rights outside Greater China to SIM0613, an antibody–drug conjugate (ADC) targeting LRRC15. Ipsen also announced a new research collaboration and option agreement with the Université de Montréal and IRICoR, encompassing two discovery-stage programs focused on novel inhibition of pathways complementary to the MAP kinase pathway. 2026 Upcoming Milestones Ipsen anticipates several key milestones across its portfolio in 2026, including: Tovorafenib (FIREFLY-1) - European regulatory decision for pediatric low-grade glioma Bylvay (BOLD) - Readout of pivotal Phase III in biliary atresia Iqirvo (ELSPIRE) - Readout of pivotal Phase III in primary biliary cholangitis Dysport (BEOND) - Readout of pivotal Phase III trials in chronic and episodic migraine IPN10200 (LANTIC) - Readout of Phase II in lateral canthal lines and forehead lines These milestones reinforce Ipsen’s commitment to advancing innovative therapies and expanding treatment options for patients worldwide. Full data from the Phase II LANTIC study of IPN10200, which demonstrated a positive first-in-class, differentiated long-acting clinical pro the initiation of Phase III, are expected to be presented in the first half of 2026 at an upcoming congress. Galderma arbitration In January 2026, the Arbitral Tribunal of the International Chamber of Commerce (ICC) issued a final decision in favor of Ipsen, dismissing the claim brought by Galderma in connection with Ipsen’s termination of the R&D agreement. The Tribunal confirmed Ipsen’s full rights to its clinical-stage toxin programs in the aesthetics field, including IPN10200. Ipsen continues to assess all options to maximize the value of its long-acting program. Environmental, Social and Governance Ipsen took important steps in 2025 to deliver its ambitious sustainability strategy, continuing to embed sustainability across its operations and decision-making. From reducing its environmental footprint to advancing patient access and strengthening its workplace culture, Ipsen reinforced its commitment to delivering progress for patients, employees, communities, and the planet. Ipsen made good progress across multiple environmental targets, including: 54% reduction in Scopes 1 & 2 greenhouse gas emissions (vs. a 2019 baseline) 16% reduction in Scope 3, fully in line with our 2030 targets (vs. a 2019 baseline) 100% of Ipsen’s global electricity now comes from renewable sources 55% of the company fleet now comprised of electric vehicles as of 2025 through the Fleet for Future Project Ipsen received an A rating from CDP for our best-practice environmental actions and transparency, and for demonstrating our comprehensive understanding of environmental dependencies, risks, and opportunities. Ipsen is proud to be one of the first biopharmaceutical companies to achieve full gender parity within the Executive Leadership Team, and with women now representing 53% of the Global Leadership Team.

Breakthrough Therapy Designation granted for investigational therapy IPN60340 in combination with venetoclax and azacitidine in first line unfit acute myeloid leukemia PARIS, FRANCE, 13 JANUARY 2026 – Ipsen (Euronext: IPN; ADR: IPSEY) announced today that the U.S. Food and Drug Administration (FDA) has granted Breakthrough Therapy Designation (BTD) for IPN60340 in combination with venetoclax and azacitidine (Ven-Aza) in first line unfit acute myeloid leukemia, an aggressive blood cancer affecting older adults. IPN60340 is an investigational first-in-class monoclonal antibody targeting BTN3A, a key immune-regulatory molecule broadly expressed across cancer. Breakthrough Therapy Designation is intended to expedite the development and review of medicines for serious or life-threatening conditions with evidence of a substantial clinical improvement. IPN60340 previously received Orphan Drug Designations from the U.S. Food and Drug Administration and European Medicines Agency in July 2025. “This Breakthrough Therapy Designation recognizes both the urgent need for new treatment options for people living with acute myeloid leukemia and the promising data seen so far in the development program for IPN60340,” said Christelle Huguet, PhD, EVP and Head of R&D, Ipsen. “We look forward to working closely with the FDA as we advance to the next stage of clinical development and continue to deliver medicines with the potential to be transformative to people living with cancer.” This Breakthrough Therapy Designation is based on data from the Phase I/II EVICTION trial. Updated clinical data orally presented at the American Society of Hematology (n=57)1 from the EVICTION trial showed treatment with IPN60340 in combination with Ven-Aza achieved very encouraging high responses. In this single-arm trial, treatment with IPN60340 and Ven-Aza (n=38), resulted in a near doubling of the complete response relative to those seen in historical standard of care data across all molecular subtypes in newly diagnosed patients including sub-types typically less responsive to standard of care (Ven-Aza).1,2 IPN60340 in combination with Ven-Aza was also shown to be well tolerated, underscoring IPN60340’s potential as a novel immunotherapy to improve outcomes for patients with AML. Based on these preliminary data, we look forward to discussing the design of the Phase II/III development plans with the FDA for IPN60340 in H1 2026. About the EVICTION trial EVICTION is a first-in-human, dose-escalation (Part 1) and cohort-expansion (Part 2) clinical trial of IPN60340 (ICT01) in patients with various advanced relapsed or refractory solid or hematologic cancers that have exhausted standard-of-care treatment options, as well as newly-diagnosed AML. More information on the EVICTION trial can be found at clinicaltrials.gov (NCT04243499). About IPN60340 (ICT01) IPN60340 is a humanized, anti-BTN3A (also known as CD277) monoclonal antibody that promotes the recognition and elimination of tumor cells by γ9δ2 T cells, which are responsible for immunosurveillance of malignancy and infections. The three isoforms of BTN3A targeted by IPN60340 are overexpressed on many solid tumors (e.g., melanoma, urothelial cell, colorectal, ovarian, pancreatic, and lung cancer) and hematologic malignancies (e.g., leukemia and lymphomas) and are also expressed on the surface of innate (e.g., γδ T cells and NK cells) and adaptive immune cells (T cells and B cells). Binding to BTN3A is essential for the activation of the anti-tumor immune response of γ9δ2 T cells. By altering the conformation of BTN3A, IPN60340 promotes this binding, thereby selectively activating circulating γ9δ2 T cells. This leads to migration of γ9δ2 T cells out of the circulation and into the tumor tissue, and triggers a downstream immunological cascade through secretion of pro-inflammatory cytokines, including but not limited to IFNγ and TNFα, further augmenting the anti-tumor immune response. Anti-tumor activity and efficacy of IPN60340 have been shown in patients across several cancer indications. IPN60340 is an investigational therapy under evaluation for people 75 years or older living with acute myeloid leukemia who due to comorbidities are prevented from receiving treatment with intensive chemotherapy.
