Item 1.01. Entry into a Material Definitive Agreement.

On June 6, 2019, Vertex Pharmaceuticals Incorporated (“Vertex”) entered into an Agreement and Plan of Merger (the “Merger Agreement”) with Exonics Therapeutics, Inc. (“Exonics”), VXP Merger Sub, Inc., a wholly-owned subsidiary of Vertex (“Merger Sub”), and Shareholder Representative Services LLC (solely in its capacity as shareholders’ representative thereunder). The Merger Agreement provides that, upon the terms and subject to the conditions set forth in the Merger Agreement, Merger Sub will merge with and into Exonics (the “Merger”), with Exonics surviving the Merger as a wholly-owned subsidiary of Vertex.

Under the terms of the Merger Agreement, Vertex has agreed to upfront payments of approximately $245 million in cash upon consummation of the transaction, subject to certain adjustments, and approximately $74 million of additional payments to certain equity holders at later dates, subject to certain terms and conditions, plus up to an aggregate of up to $728 million in contingent payments payable upon achievement of various clinical and regulatory milestones in respect of the research, development and commercialization of products intended for the treatment of Duchenne muscular dystrophy and Myotonic Dystrophy Type 1.

A portion of the upfront consideration will be placed in escrow upon closing of the Merger to satisfy certain indemnification obligations of the parties as described in the Merger Agreement. Any escrow proceeds that are not used to satisfy indemnity claims or secure pending indemnity claims will be released to the former holders of capital stock of Exonics 15 months after the closing of the Merger. In addition, subject to certain limitations described in the Merger Agreement, Vertex may set off indemnification payments owed by former holders of capital stock of Exonics following the closing of the Merger against contingent payments owed to such holder.

The Merger Agreement and the consummation of the transactions contemplated thereby have been approved by the board of directors and the shareholders of Exonics. The completion of the Merger is subject to certain conditions, including the expiration or termination of the applicable waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended. Vertex anticipates that the transaction will be completed in the third quarter of 2019. Vertex intends to fund the acquisition using cash on hand or other sources of immediately available funds.

The foregoing description of the Merger Agreement does not purport to be complete and is qualified in its entirety by reference to the Merger Agreement, which will be filed with Vertex’s Quarterly Report on Form 10-Q for the fiscal quarter ended June 30, 2019.



Pursuant to the requirements of the Securities Exchange Act of 1934, the Registrant has duly caused this report to be signed on its behalf by the undersigned hereunto duly authorized.
