Regulatory News:

This press release may not be published or distributed, directly or indirectly in or into the United States, or any other jurisdiction where such action is subject to legal restrictions.

The rights issue in BioInvent (STO:BINV) of MSEK 48.9, with preferential rights for the company’s shareholders, has been oversubscribed. The subscription period ended on 11 April 2014. Approx. 95 per cent of the shares offered have been subscribed for with subscription rights and in total notifications to subscribe for shares without subscriptions rights have been received corresponding to 101 per cent of the shares offered.

Due to an administrative error with the Custodial bank, the Company's largest shareholder Van Herk Investments B.V. has sold subscription rights corresponding to 3,193,312 shares instead of exercising these in accordance with the subscription undertaking. Van Herk Investments B.V. has in writing to the Company undertaken to in a supervised manner purchase the equivalent number of shares in the market during a period estimated to amount to about sixty trading days and informed that Van Herk Investments B.V. will announce to the market when the share purchase is completed. Due to this occurrence an addendum prospectus will be prepared which is estimated to be published prior to the Stock Exchange opening on Thursday 17 April 2014 together with information about the final outcome of the rights issue. The Company deems that the previously announced timetable for registration of the new share issues and admission to trading will not be effected.

Advisors

Erik Penser Bankaktiebolag is acting as financial advisor and Mannheimer Swartling Advokatbyrå AB is acting as legal advisor to BioInvent in connection to the new share issues.
