Jan 30, 2015

SAN RAFAEL, Calif., Jan. 30, 2015 (GLOBE NEWSWIRE) -- BioMarin Pharmaceutical Inc. (Nasdaq:BMRN) announced today the final results of, and the completion of the subsequent offering period relating to, the previously announced tender offer by its subsidiaries, BioMarin Falcons B.V. and BioMarin Giants B.V. (together, "Purchaser"), to acquire all of the outstanding ordinary shares of Prosensa Holding N.V. (Nasdaq:RNA) at a purchase price of $17.75 per share, net to the seller in cash (the "Cash Consideration"), plus one non-transferrable contingent value right to receive cash payments of up to $4.14 per share in the aggregate upon the achievement of certain product approval milestones ("CVR"), in each case, without interest thereon and less any applicable withholding taxes. 

The subsequent offering period related to the tender offer expired at 6:00 p.m., New York City time, yesterday. Based on information provided by the depositary for the offer, a total of 34,970,514 shares, representing approximately 96.76% of the aggregate number of shares outstanding, had been accepted for payment and paid for (including shares accepted for payment and paid for in the initial offering period relating to the offer) as of the expiration of the subsequent offering period. Purchaser immediately accepted for payment and has promptly paid for or will promptly pay for any shares that were tendered during the subsequent offering period for the same form and amount of offer consideration as in the initial offering period relating to the offer.

Now that the offer has closed, BioMarin and Purchaser intend to complete a corporate reorganization of Prosensa and its subsidiaries through a sale of all of Prosensa's assets to, and assumption of all of Prosensa's liabilities by, BioMarin Falcons (the "Asset Sale"), followed by the dissolution and liquidation of Prosensa. The Asset Sale and subsequent dissolution and liquidation of Prosensa is a process available to Purchaser under Dutch law to ensure that Purchaser becomes the owner of all of Prosensa's business operations. In conjunction with the Asset Sale, Prosensa will issue an advanced liquidation distribution to its remaining shareholders with each remaining shareholder receiving a cash payment equal to the Cash Consideration per share as well as one CVR per share, without interest thereon and less any applicable withholding taxes. If a shareholder of Prosensa holds its shares of Prosensa through the Depositary Trust Company, it is anticipated that the shareholder will receive its advanced liquidation distribution through the Depositary Trust Company. Following the Asset Sale and advanced liquidation distribution, Prosensa is not expected to have any assets and no further distributions are expected to be made.
