DEREGISTRATION OF SECURITIES

Horizon Pharma, Inc. (the “Company”) is filing this Post-Effective Amendment to its Registration Statement on Form S-3 to withdraw and remove from registration the unissued and unsold shares of the Company’s common stock, par value $0.0001 per share, issuable by the Company pursuant to its Registration Statement on Form S-3 originally filed with the Securities and Exchange Commission on April 10, 2012 on Form S-1 (Registration No. 333-180650) (the “Registration Statement”).

On September 18, 2014, the Company’s stockholders approved, at a special meeting of the Company’s stockholders, a Transaction Agreement and Plan of Merger, dated as of March 18, 2014, as amended (the “Merger Agreement”), by and among the Company, Horizon Pharma plc (formerly Vidara Therapeutics International Ltd.) (“New Horizon”), Vidara Therapeutics Holdings LLC, Hamilton Holdings (USA), Inc. and Hamilton Merger Sub Inc. (“Merger Sub”). Pursuant to the Merger Agreement, on September 19, 2014, among other things, Merger Sub merged with and into the Company (the “Merger”), with the Company surviving the Merger as a wholly-owned subsidiary of New Horizon. In the Merger, all outstanding shares of the Company’s common stock were canceled and converted into the right to receive ordinary shares of New Horizon on a one-for-one basis.

As a result of the Merger, the Company terminated all offerings of its securities pursuant to its existing registration statements, including the Registration Statement. In accordance with an undertaking made by the Company in the Registration Statement to remove from registration, by means of a post-effective amendment, any shares of its common stock which remain unsold at the termination of the offering, the Company hereby removes from registration all shares of its common stock registered under the Registration Statement which remained unsold as of the effective time of the Merger.
