Divident policy

In the last 5 financial years the Company did not pay out dividends. The Management Board of the Company adopts the current dividend policy to the Company’s economic situation, taking into account the scope of necessary investments. At present the Company is in the development stage and it seems expedient to retain the possible profit in the Company.

Current rate


The primary goal of Mabion is to develop, manufacture and market oncology drugs which are biosimilar to the original biotechnology drugs already present on the market (so called reference drugs). Currently, the Company’s priority is to launch MabionCD20 onto as many international markets as possible. The Company intends to carry out the marketing authorisation process on its own, under a centralised procedure for the whole European Union where the system of registration for biosimilars is well-regulated. Moreover, one of the Company’s objectives is to launch drugs onto the American market. When it comes to regions with a less regulated system of marketing authorisation, such as African and Asian countries, Mabion plans to carry out both the sales and the whole authorisation procedure through local leading pharmaceutical companies on the basis of distribution agreements. The market of biotechnology drugs is already very attractive and its worth should increase significantly in the course of upcoming years. The strategy adopted by Mabion S.A. provides for the continuation of research and development pursuits in the field of new biotherapeutics. It's anticipated that the development strategy will be financed mainly by the Company’s own funds, as well as grants from the EU and national funds.

The Company annually updates the development plan for medicinal products, and may change it from time to time.

On 3 April 2019, following the annual review and update of the development strategy for medicinal products, the Company's Management Board adopted a resolution approving changes to the existing development strategy. In accordance with the resolution, the catalogue of projects which the Company is interested in implementing, now or in the future, either independently or with partners, has been changed. The Company has also qualified research and development projects into three groups of projects, i.e. active projects, new projects that were planned for 2019, and partnership projects.

  • Active projects

A group of projects of the greatest importance for the Company, for which the Company conducts work and invests funds. This group includes the following current projects: MabionCD20, MabionMS and MabionEGFR.

  • New projects started in 2019

Projects for which the Company started research and development work in the second half of 2019 include projects related to development of three medicines biosimilar to the following reference drugs: Prolia and Xgeva (both based on denosumab antibody) and Xolair (based on omalizumab antibody).

  • Partnership projects

Projects for which the Company is considering commencement of implementation in the medium or long term, preferentially in cooperation with a partner. They will include projects concerning, among others, autoimmune and oncological diseases.
