BioInvent reorganises

Focusing resources on BI-204 and new cancer projects

Lund, Sweden – 29 June 2012 – BioInvent International AB (OMXS: BINV) announces
today that the company has decided to initiate negotiations with trade unions
regarding organisational changes. The decision is due to the fact that
development of the antithrombotic agent TB‑402 has been stopped. The company’s
resources will therefore be reprioritised to focus on the continued development
of BI‑204 for the treatment of acute coronary artery disease and new and
existing cancer projects such as BI‑505.

The new organisation is planned to have 68 full-time employees compared with the
current 89. The reduction in work force and other reprioritisations are expected
to result in cost savings of around SEK 15 million on a full-year basis, fully
effective from January 2013.

Svein Mathisen, President and CEO of BioInvent, comments: “We regret the fact
that the changes in our organisation will impact a number of our employees, but
consider it necessary to take better advantage of the opportunities provided by
positive study data later this year. We are now focusing our resources on the
most promising projects, for which we expect to present study results in two of
the most advanced projects during the forthcoming quarter.

We will also strengthen the company as a trustworthy partner for companies using
our technology to develop proprietary antibody drugs. We have important revenues
from these collaborations today - revenues which are expected to increase as our
partners bring the product candidates forward through the development chain.

The combined project portfolio with proprietary projects and with projects run
by our partners provides a solid foundation for long term growth and to create
shareholder value.”

The company has initiated negotiations in accordance with the Swedish Co
-Determination Act in respect of the planned personnel changes. Once
negotiations are complete, a final decision will be taken on the relevant
organisational and personnel matters.
