"We are pleased to work with Eckert & Ziegler, a global leader in radiopharmaceutical manufacturing. This agreement will expand the potential of Radio-DARPins as vectors for precise delivery of therapeutic alpha-emitting isotopes to tumors, now including Actinium-225, in addition to Lead-212 through our long-term strategic partnership with Orano Med," said Alexander Zürcher, COO of Molecular Partners. He added: "The promise of Radio-DARPins is underlined by the progress of our lead candidate MP0712, targeting DLL3, having just opened the Phase 1/2a trial for the treatment of patients with small cell lung cancer (SCLC)".

Under the non-exclusive agreement, Eckert & Ziegler will support Molecular Partners with a comprehensive range of services covering development activities for Radio-DARPins with Actinium-225 (225Ac) and Lutetium-177 (177Lu) payloads. The development agreement will leverage Eckert & Ziegler’s state-of-the-art laboratories, including its newly established Alpha Laboratory in Berlin, Germany, dedicated exclusively to work with alpha emitters.

For its growing Radio-DARPin pipeline, Molecular Partners is evaluating various radio-nuclides to tailor Radio-DARPin candidates to patient needs – matching vector and isotope properties with target and disease biology. The Company plans to present pre-clinical data on Radio-DARPins’ suitability with multiple isotopes at the 3rd Global Radiopharmaceuticals Development Summit in March 2026 in Shanghai, China.

Eckert & Ziegler is a globally leading specialist for isotope-related components in nuclear medicine and radiation therapy, offering a broad range of services and products from early development work to contract manufacturing and distribution.

"Supporting highly innovative companies such as Molecular Partners in developing their promising technology platforms is a key objective of our group," said Dr. Harald Hasselmann, CEO of Eckert & Ziegler. "Bringing together our expertise in isotopes, radiochemistry and development infrastructure with our partners’ innovations will enable patients worldwide to benefit from new treatments in the future."

About Radio-DARPins

Molecular Partners’ Radio-DARPins are designed as ideal vectors for precise delivery of potent alpha-emitting isotopes to tumor lesions and have the potential to unlock a broad range of tumor targets for targeted radiopharmaceuticals. Building on the DARPins’ unique properties, Molecular Partners has developed a proprietary Radio-DARPin platform to address historic limitations of radioligand therapy, such as kidney accumulation and toxicity, and suboptimal tumor uptake. Molecular Partners’ Radio-DARPins addresses these limitations through half-life extension technologies and surface engineering approaches, while preserving the advantages of the small protein format.

About ccRCC
Clear cell renal cell carcinoma is the most common subtype of kidney cancer and is often driven by mutations in the Von Hippel-Lindau (VHL) gene, contributing to the tumours highly vascular nature. Most patients today receive combinations or sequences of immunotherapy and targeted therapies, such as VEGFR tyrosine kinase inhibitors. However, after progression on these regimens, options are limited. This highlights the need for new therapeutic strategies for patients in later lines of treatment.

About the RENALUT study
The RENALUT trial explores a novel therapeutic approach for metastatic ccRCC by leveraging radioligand therapy (RLT) targeting PSMA (prostate-specific membrane antigen). Although PSMA is best known for its role in prostate cancer, it is also expressed in the tumour neovasculature of ccRCC, making it a promising therapeutic target1. PSMA‑targeted imaging has shown strong performance in identifying metastatic ccRCC, supporting the idea that PSMA‑directed therapy with [177Lu]Lu‑PSMA‑617 may also be an effective treatment for this disease2,3. By building on the established use of [177Lu]Lu‑PSMA‑617 in metastatic castration resistant prostate cancer, RENALUT aims to determine whether this approach can benefit ccRCC patients who have exhausted standard treatments and currently face very limited options.

Participating sites and collaboration
The activation of the first site marks a significant milestone for this innovative trial, which will involve 11 centres across Europe. The study is led by EORTC’s Genito-Urinary Cancer Group (GUCG) and supported by a network of international collaborators.

By exploring PSMA-targeted RLT in ccRCC, RENALUT aims to address an urgent unmet need and pave the way for future treatment strategies in kidney cancer.

I. Cash position

As of December 31, 2025, the Company’s cash and cash equivalents amounted to €101.1 million compared with €81.8 million as of December 31, 2024 and €119.0 million as of September 30, 2025.

In 2025, cash utilization is mainly the result of our research and development efforts in our Acute on-Chronic Liver Failure (ACLF) franchise (notably VS-01, NTZ/G1090N, SRT-015, CLM-022, and VS-02 HE), as well as GNS561 in cholangiocarcinoma (CCA). Cash utilization is offset notably by the €26.55 million milestone received in July 2025 (invoiced in May 2025) upon pricing and reimbursement approval of Iqirvo (elafibranor) in Italy, the third major European country to do so, as part of our long-term strategic partnership with Ipsen (the "Ipsen Agreement") signed in December 2021.

In January 2026, GENFIT exercised its option to receive (and did in fact receive) the second installment of the Royalty Financing agreement totaling €30.0 million. Both this amount, as well as the first commercial milestone of €17.0 million ($20.0 million) that GENFIT will receive as part of the Ipsen Agreement, are not included in cash and cash equivalents as of December 31, 2025.

We expect that our existing cash and cash equivalents will enable us to fund our operating expenses and capital expenditure requirements beyond the end of 2028, enabling the Company to further develop its R&D pipeline focused on ACLF and support general corporate purposes. This is based on current assumptions and programs and does not include exceptional events. This estimation assumes (i) our expectation to receive significant future commercial milestone revenue pursuant to the Ipsen Agreement and Ipsen meeting its sales-based thresholds and (ii) drawing down the third and final, optional installment under the Royalty Financing agreement.

Revenue
Revenues for 2025 amounted to €65.4 million compared to €67.0 million for the same period in 2024.

Revenue Year ended
(in € millions) 31/12/2024 31/12/2025
Royalty revenue 2.7 21.8
Milestone revenue 48.7 43.6
Revenue initially deferred from the Licensing Agreement (Ipsen) 15.3 -
Revenue from the Part B Transition Services Agreement (Ipsen) 0.1 -
Other revenue 0.2 -
TOTAL 67.0 65.4
Royalty revenue is entirely attributable to worldwide sales of Iqirvo (elafibranor), which amounted to $208 million in 2025.

Milestone revenue in 2025 is comprised of two milestones:

GENFIT’s first commercial milestone of €17.0 million ($20.0 million) after Ipsen’s Iqirvo exceeded the $200 million threshold in its first full year of net sales, and
GENFIT’s milestone of €26.55 million upon pricing and reimbursement approval of Iqirvo (elafibranor) in Italy, the third major European country to do so.
II. Corporate update and program highlights

Acute On-Chronic Liver Failure (ACLF)

The key highlight for this pipeline segment in the fourth quarter 2025 was the progress of our lead program, G1090N, which generated preliminary Phase 1 data readout showing a safety profile and a robust anti-Inflammatory activity evidenced through functional ex vivo assays on blood samples from study participants and cirrhotic donors. As communicated earlier, GENFIT will engage with regulatory authorities to determine the best approach for progressing to a Phase 2 proof-of-concept in inflammatory conditions such as ACLF, where systemic immune dysregulation is a critical driver of disease progression.

Other assets developed to address the unmet medical need in ACLF continued their preclinical evaluation during the fourth quarter of 2025 to fully assess their potential before advancing into clinical development.

Cholangiocarcinoma (CCA)

The main highlight in this indication in the fourth quarter of 2025 was the highly encouraging early data delivered from the ongoing Phase 1b study evaluating investigational drug GNS561 with a MEK inhibitor (MEKi) in KRAS mutated CCA, positioning this novel combination as a potential new therapeutic approach for difficult-to-treat cancers. Phase 1b dose escalation continues as planned to confirm the activity signal, with new data for next patient cohorts and recommended Phase 2 combination doses expected in the first half of 2026. Phase 2 initiation remains targeted for the second half of 2026.

Ipsen’s Iqirvo (elafibranor) in Primary Biliary Cholangitis (PBC) and Primary Sclerosing Cholangitis (PSC)

PBC: Iqirvo’s net sales for the fourth quarter 2025 amounted to $88 million, bringing full-year 2025 sales to $208 million, triggering the first commercial milestone payment to GENFIT one year ahead of schedule.

PSC: Ipsen confirmed the initiation of the first and only global Phase 3 clinical trial, addressing a significant unmet medical need, as no approved therapies currently exist for this severe and progressive disease. PSC represents a substantial untapped market opportunity, comparable in size to second line PBC. Should Iqirvo ultimately receive regulatory approval for this indication, GENFIT would be eligible for additional milestone payments as well as additional double‑digit royalties.

"We are excited about the potential of TSC-101 to treat residual disease and prevent relapse in patients undergoing hematopoietic cell transplantation," said Gavin MacBeath, Ph.D., Chief Executive Officer. "We have now enrolled over ten patients in Cohort C of the ALLOHA study where we are treating patients with our new commercial-ready manufacturing process. We look forward to sharing data from this cohort in the second quarter of this year, prior to launching our Phase 3 study. We are also pleased to announce that the FDA has cleared our IND applications for TSC-102-A01 and TSC-102-A03, and we look forward to initiating a Phase 1 trial with these candidates in the second half of this year. We believe the addition of these product candidates will nearly double the addressable U.S. patient population in our heme program."

"During the Tandem Meetings of ASTCT and CIBMTR, we highlighted the relationship between donor chimerism and long-term outcomes in patients following HCT," added Chrystal U. Louis, M.D., Chief Medical Officer. "Specifically, patients that achieved complete donor chimerism by month two after transplant using a high-sensitivity assay have a significantly lower probability of relapse (HR=4.6, p=0.02) compared to those who did not achieve complete donor chimerism. We look forward to sharing early chimerism data from Cohort C and formally initiating our pivotal study for TSC-101."

The Phase 1 ALLOHA study is evaluating TSC-101 in A*02:01-positive patients with heme malignancies undergoing allogeneic hematopoietic cell transplantation (allo-HCT). TScan plans to share safety and early chimerism data from Cohort C in the second quarter of 2026. The Company also plans to launch a pivotal trial for TSC-101 in patients with acute myeloid leukemia (AML) and myelodysplastic syndromes (MDS) in the second quarter of 2026.

The U.S. FDA clearance of INDs for TSC-102-A01 and TSC-102-A03 continues the momentum in TScan’s heme program by expanding HLA coverage to include patients who are HLA-A*01:01-positive or HLA-A*03:01-positive, respectively. These TCR-T therapy candidates target CD45, a protein broadly expressed in heme cells but absent in non-heme tissues.

TScan plans to initiate a Phase 1 trial for both TSC-102-A01 and TSC-102-A03 in the second half of 2026. Products will be manufactured using the commercial-ready process and will enroll patients with various hematologic malignancies undergoing allo-HCT using either reduced intensity conditioning or myeloablative conditioning. The multi-center Phase 1 trial is designed to assess safety and initial efficacy of these TCR-T therapy candidates.
