Under the licensing agreement in relation to the Exclusive Partnership, IMPACT has granted exclusive manufacturing, development and commercialisation rights of senaparib for maintenance monotherapy for advanced epithelial high-grade ovarian, fallopian tube and primary peritoneal cancer to Pharmanovia in 66 countries, including, among others, all 27 European Union member states, as well as the United Kingdom, Norway, Iceland, Switzerland, Liechtenstein, Australia, New Zealand and countries in the Middle East and North Africa.

IMPACT will work closely with Pharmanovia to advance the commercialisation of senaparib in the collaboration territories. By leveraging Pharmanovia's specialist expertise and established infrastructure, we expect senaparib to reach target patients in the collaboration territories more quickly following approval, helping to deliver high-quality treatment options to address unmet medical needs. This collaboration will not only enhance the brand recognition of the product and IMPACT on a global scale, but also further broaden IMPACT's strategic layout for global commercialisation. We expect that this collaboration will have a positive and profound impact on our development.

The Company is actively advancing the clinical and regulatory development of senaparib globally. Its Marketing Authorisation Application (MAA) in Europe was formally accepted by the EMA in August 2025, with approval expected in the second half of 2026.
