Lund, Sweden – 19 June 2013 – BioInvent International AB (OMXS: BINV)

The Board of Directors of BioInvent has resolved, by virtue of the authorisation from the Annual General Meeting, to conduct a rights issue of approximately SEK 22 million with pre-emptive right for the shareholders of the company. The purpose of the rights issue is to strengthen the company’s financial position and to increase the commercial flexibility.

The rights issue is fully guaranteed through subscription undertakings from current owners and through underwriting agreements with current owners and other investors. The subscription price has been set at SEK 2.10 per share, the record date for participation in the rights issue is 1 July 2013 and the subscription period runs from and including 5 July 2013 until and including 19 July 2013.

Background and reasons
BioInvent has through its technology platform, n-CoDeR®, developed a portfolio of internal and partnered drug candidates. The internal portfolio currently consists of three drug candidates within oncology of which BI-505 is undergoing clinical phase II trials. For the other two projects, clinical trials are expected to start 2014 / 2015. In addition, the company has a number of promising projects in research phase.

BioInvent has eight development projects in pre-clinical phase together with five partners. BioInvent expects that some of these projects will advance into clinical trials during 2013, which would lead to milstone revenues. Furthermore, the company sees good business opportunities in its current contacts regarding the company’s antibody technologies, n-CoDeR® and F.I.R.S.T™. BioInvent is currently in negotiations and discussions with potential partners and sees potential for these to result in new agreements and revenues.

The company has reviewed its corporate strategy and recruited a new CEO, Mikael Oredsson, who will assume his position on 19 August. Significant cost reductions have been implemented in the last year. The cost reductions are now in full effect, which gives the foundation to reach a position where the operational costs, to a large extent, are funded by revenues from partners.

To finance the operations throughout the second half of 2013 and to continue the development of existing projects independently of expected revenues from partner projects and ongoing business development activities, where the timing is less predictable, the company needs to strengthen its financial position. Further, financial endurance is an important aspect when negotiating with potential license partners and other external parties.

The addition of around SEK 22 million before transaction costs is expected to finance the company throughout 2013. In addition, revenues will be generated from partner projects and ongoing business development activities. Later this year, the company will review its long term strategies when the new CEO has assumed his position.

Terms for the rights issue
The company's shareholders will have pre-emptive right to subscribe for new shares in proportion to the number of shares previously held by them. Seven (7) existing shares entitle to subscription of one (1) new share at a subscription price of SEK 2.10. The record date for participation in the rights issue is 1 July 2013.

In the event that all new shares are not subscribed for with pre-emptive right, such shares shall be allotted to shareholders and others who have subscribed for shares without subscription rights. Such allotment shall firstly be made to those who have subscribed for shares by exercise of subscription rights. The subscription period runs from 5 July up to and including 19 July 2013 or such later date as the Board of Directors may decide.

The rights issue may result in an increase of the share capital of no more than SEK 844,866.08 and an increase in the total number of share of no more than 10,560,826 shares.

Subscription undertakings and underwriting guarantees
A number of BioInvent’s larger shareholders, including the company’s two largest shareholders O.G.B.B. A. van Herk B.V. and B&E Participation AB, who together represent 22.4 percent of the shares, have committed to subscribe for their pro rata share of the rights issue, corresponding to a total of MSEK 5,0. In order to secure that the rights issue is fully subscribed, the company has entered into underwriting agreements with a number of current and external investors in a total amount of MSEK 17,2.

Overallotment option
In the event of an over-subscription in the rights issue, the Board of Directors intends, if it is deemed desirable, to resolve on the issuance of additional shares up to a maximum total of 528,041 shares at a subscription price of SEK 2.10 per share, which would add to the company an additional SEK 1 million, approximately. The number of shares issued in the overallotment option falls within the limits of the authorisation from the Annual General Meeting, which authorises the Board of Directors to issue a maximum of 11,088,867 shares.

Allotment of the shares of the overallotment option shall be made in accordance with the allotment principles for the rights issue. The reason for the deviation from the shareholders’ pre-emptive right is to take advantage of the possibility for the company’s to receive additional proceeds in the event of an over-subscription of the rights issue.
