The Purchaser acquired the Shares pursuant to the Offer (as defined in Item 4) for approximately $612 million. The Purchaser obtained funding for such acquisition from Parent’s cash on hand.

The information set forth or incorporated in Item 4 is incorporated herein by reference.

Item 4. Purpose of Transaction

On November 23, 2014, Prosensa, Parent and BioMarin Falcons entered into a Purchase Agreement (the “Purchase Agreement”). In accordance with the Purchase Agreement, on December 12, 2014, the Purchaser commenced a tender offer for all of Prosensa’s outstanding Shares 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 (“CVR”) per Share, which represents the contractual right to receive cash payments of up to $4.14 per Share in the aggregate upon the achievement of certain product approval milestones (the Cash Consideration, together with one CVR, the “Offer Price”), in each case, without interest thereon and less any applicable withholding taxes (the “Offer”), upon the terms and subject to the conditions set forth in the Offer to Purchase, dated as of December 12, 2014 (as amended, the “Offer to Purchase”), which is incorporated by reference to Exhibit (a)(1)(A) of the Tender Offer Statement on Schedule TO filed by Parent and the Purchaser with the Securities and Exchange Commission (the “SEC”) on December 12, 2014 (as amended, the “Schedule TO”), and the related Letter of Transmittal, dated as of December 12, 2014, which is incorporated by reference to Exhibit (a)(1)(B) of the Schedule TO.

The information set forth in the sections of the Offer to Purchase entitled “Summary Term Sheet,” “Introduction,” “The Offer — 6. Price Range of Shares; Dividends,” “The Offer — 9. Source and Amount of Funds,” “The Offer — 10. Background of the Offer; Past Contacts or Negotiations with Prosensa,” “The Offer — 11. The Purchase Agreement; Other Agreements,” “The Offer — 12. Purpose of the Offer; Plans for Prosensa,” “The Offer — 13. Certain Effects of the Offer,” and “The Offer — 14. Dividends and Distributions,” is incorporated herein by reference.

On January 15, 2015, the initial offering period relating to the Offer closed, and Purchaser immediately launched a subsequent offering period. American Stock Transfer & Trust Company, LLC, the depositary for the Offer, advised Purchaser and Prosensa that 33,746,104 Shares were validly tendered and not properly withdrawn pursuant to the Offer (excluding Shares tendered pursuant to notices of guaranteed delivery procedures that had not yet been delivered in satisfaction of such guarantee), which represented approximately 93.4% of all outstanding Shares as of the Offer’s expiration date. Purchaser accepted for payment and promptly made payment for all Shares that were validly tendered and not properly withdrawn in the initial offering period.

The subsequent offering period is scheduled to expire at 6:00 p.m., New York City time, on January 29, 2015. As of January 23, 2015, an additional 733,864 Shares have been tendered in the subsequent offering or via satisfaction of guaranteed deliveries. Purchaser has accepted for payment and promptly made payment for all Shares that have been so validly tendered.

Following the expiration of the subsequent offering period, Purchaser intends to complete a corporate reorganization of Prosensa and its subsidiaries (the “Post-Closing Reorganization”). As part of the Post-Closing Reorganization, Purchaser may complete a sale of all of Prosensa’s assets to BioMarin Falcons or its designee, followed by the dissolution and liquidation of Prosensa. Purchaser may, alternatively, commence a statutory buy-out of Shares from any remaining minority shareholder in accordance with Dutch law, or if BioMarin determines that it is not reasonably practicable to consummate the Post-Closing Reorganization by means of an asset sale or a statutory buy-out of Shares, subject to the prior approval of the two members of Prosensa’s supervisory board who are not designated by Purchaser and/or BioMarin, any other measure constituting a Post-Closing Reorganization. The Post-Closing Reorganization, including 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 from and after the consummation of the Post-Closing Reorganization.

In addition, following the expiration of the subsequent offering period, Purchaser, subject to and in accordance with applicable laws, intends to cause Prosensa to (i) delist the Shares from the NASDAQ, (ii) terminate Prosensa’s obligation to file reports under the Securities Exchange Act of 1934 (the “Exchange Act”), pending termination of registration of the Shares under the Exchange Act and (iii) terminate the registration of the Shares under the Exchange Act.

As a result of the closing of the initial offering period, the resignation of all pre-closing managing directors of Prosensa became effective, with the exception of Giles Campion who is not resigning. Also effective upon the closing were the resignations of all pre-closing supervisory directors, with the exception of David Mott who is not resigning. The appointments of Scott Clarke and Richard Holslag to Prosensa’s management board, and Hans Schikan, Henry Fuchs, Robert Baffi and G. Eric Davis to the supervisory board, became effective upon the closing, and the reappointments of David Mott to the supervisory board and Giles Campion to the management board became effective upon the closing as well.
