Lund, Sweden 20 April 2010 - BioInvent International AB (OMXS: BINV) today announced it will refocus its operations by tailoring its process development and manufacturing resources to proprietary product development. As a consequence contract manufacturing operations will cease.

The new organisation can be expected to have approximately 90 full-time employees compared to the current 104. This will be expected to bring reductions in fixed cost of approximately SEK 15 million on a yearly basis with effect from January 2011. The streamlining is made possible by focusing manufacturing on the needs of proprietary product development, enabling shorter and improved processes, with a planned investment of SEK 5 million in new equipment.

Svein Mathisen, CEO of BioInvent, commented, "We have demonstrated that we can generate significant value in our proprietary projects and are confident that an even stronger focus on our drug portfolio will create additional value for the company. The reorganisation is a natural step in a process that has gradually happened over a number of years.

Revenue from contract manufacturing has been an important contribution to our development; however, as proprietary projects have advanced in the value chain, their contribution has by far overshadowed the contract manufacturing revenue. We anticipate that the cost reductions we are implementing, together with increased revenues from our partners using the n-CoDeR antibody library, will outweigh the effect of ceasing our contract manufacturing activities.

We regret that the changes affect some of our employees. However we are convinced that the focus on proprietary drugs will strengt hen the company and our long-term development."

The company has initiated negotiations according to MBL (Sw. law concerning right of participation in decision-making) regarding the planned personnel changes and the final decisions will be taken after the completion of negotiations.
