DEREGISTRATION OF SECURITIES
 
These Post-Effective Amendments (the “Post-Effective Amendments”) relate to (i) the Registration Statement on Form S-1 (Registration Statement No. 333-191544) filed by Mirati Therapeutics, Inc. (“Mirati” or the “Company”) with the Securities and Exchange Commission (the “SEC”) on October 3, 2013, as amended by Amendment No. 1 filed on October 16, 2013, and (ii) the Registration Statement on Form S-1 (Registration Statement No. 333-191872) filed by the Company with the SEC on October 23, 2013 ((i) and (ii) together, collectively the “Registration Statements”). The Registration Statements registered the sale of the Company's common stock, par value $0.001 per share, for an aggregate offering price of $65,406,250.

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 Statements. In accordance with an undertaking made by Mirati in the Registration Statements to remove from registration, by means of a post-effective amendment, any of the securities that had been registered for issuance under the Registration Statements 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 Statements as of the date hereof. The Registration Statements are hereby amended, as appropriate, to reflect the deregistration of such securities. After giving effect to the Post-Effective Amendments, there will be no remaining securities registered by Mirati pursuant to the Registration Statements.
