Progressing Next Generation Technologies

Manage and Control Cash Burn

>         Reduced cash burn & lengthened cash runway >         Improved loss from continuing operations three times x        Wrote down value of manufacturing facility in 2012, sale executed in Q1 2013

Financial Performance

o   Revenue increased by DKK 134 million, 38%, from DKK 351 million in 2011 to DKK 485 million, mainly due to revenue related to our daratumumab and DuoBody collaborations with Janssen, higher Arzerra royalties, and a milestone payment from GSK. o   As the operating expenses remained at the same level as 2011, the operating loss improved by DKK 132 million, or 53%, from DKK 249 million in 2011 to DKK 117 million in 2012. o   Due to continued uncertainty, we wrote down the value of the facility from USD 58 million to zero, which resulted in the recognition of a non-cash impairment charge of approximately DKK 331 million. o   2012 year end cash position of DKK 1,516 million, compared to DKK 1,105 million as of December 31, 2011. The improvement was driven by the proceeds of approximately DKK 800 million received from the daratumumab deal,partially offset by the ongoing investment in our research and development activities.
