BioInvent International (OMXS:BINV) announced today that its preferential rights issue has been oversubscribed. The subscription period in the rights issue was concluded on 30 March 2012. The new shares will bring BioInvent SEK 104.8 million before transaction costs.

The final result of the rights issue show that 6,209,737 shares, representing 92.4 per cent of the offered shares were subscribed for by the exercise of subscription rights. Additionally, subscription forms concerning 1,531,125 shares, representing 22.8 per cent of the offered shares have been received for subscription without preferential right. The subscription price was SEK 15.60 and BioInvent's shareholders had the right to subscribe for one new share for every ten existing shares.

Those who have subscribed for shares without preferential right will be allotted shares according to the principles outlined in the prospectus, which was published on 13 March 2012. Notifications regarding allotment are expected to be distributed on or around 10 April 2012. Only those who are allotted shares will be notified.

New shares subscribed for by the exercise of subscription rights are expected to start trading on NASDAQ OMX Stockholm on 12 April 2012. Trading in shares subscribed without preferential right is expected to start on 26 April 2012.

As a consequence of the preferential rights issue BioInvent will increase its share capital by SEK 3,360,262.50 to SEK 36,962,891.
