Orexo receives MGBP 5 milestone payment for Abstral® in Europe and records OX-MPI non-cash impairment charge of MSEK 62

Uppsala, Sweden – December 11, 2015 – Orexo AB (publ) today announced that the annual sales of Abstral in Europe has passed MEUR 67.5 during 2015, which triggers a milestone payment of MGBP 5 (approx. MSEK 63.8) to Orexo AB (”Orexo”) from the commercial partner in Europe ProStrakan Group plc (”ProStrakan”).

According to the agreement from June 2012, with ProStrakan for Abstral sales in Europe, Orexo receives a fixed and non-conditional royalty of MGBP 55, a variable royalty for annual sales exceeding MEUR 42.5 and milestone payments of up to MGBP 10. With the announced MGBP 5 milestone payment Orexo has earned all milestone payments associated with the ProStrakan European agreement.

Orexo has further decided to record a non-cash charge of MSEK 62 related to an impairment of the OX-MPI asset. Orexo still considers OX-MPI an attractive asset and will continue the dialogue with potential partners, however as part of the annual impairment assessment it has been decided to fully write down the value of the asset.

Both events will have full financial impact in the fourth quarter of 2015.

”I am pleased to follow the continued success of our commercial partner ProStrakan with Abstral in Europe. The performance of Abstral in Europe is a strong evidence of the patient and physician preference of the attributes of Orexo’s sublingual products and this performance enables Orexo to continue investing in the commercialization of Zubsolv® and in development of potential new formulation platforms,” said Nikolaj Sørensen, CEO and President of Orexo AB.
