DEREGISTRATION OF SECURITIES

 

•

Registration Statement No. 333-207848, originally filed with the SEC on November 6, 2015, relating to the registration of an unspecified number of the Company’s common stock, par value $0.001 per share, preferred stock, par value $0.001 per share, and warrants, up to a maximum aggregate offering price of $300,000,000.

On January 23, 2024, Vineyard Merger Sub Inc., a Delaware corporation (“Merger Sub”) and a wholly owned subsidiary of Bristol-Myers Squibb Company, a Delaware corporation (“BMS”), completed its merger (the “Merger”) with and into Mirati pursuant to the terms of the Agreement and Plan of Merger, dated October 8, 2023 (the “Merger Agreement”), by and among BMS, Merger Sub, and Mirati. Mirati was the surviving corporation in the Merger and, as a result, is now a wholly owned subsidiary of BMS.

As a result of the Merger, Mirati has terminated all offerings and sales of securities pursuant to the Registration Statement. In accordance with an undertaking made by Mirati in the Registration Statement to remove from registration, by means of a post-effective amendment, any of the securities that had been registered for issuance under the Registration Statement that remain unsold at the termination of such offering, Mirati hereby removes from registration all of such securities registered but remaining unsold under the Registration Statement as of the date hereof. The Registration Statement is hereby amended, as appropriate, to reflect the deregistration of such securities. After giving effect to the Post-Effective Amendment, there will be no remaining securities registered by Mirati pursuant to the Registration Statement.
