On August 9, 2017, Coherus BioSciences, Inc. (the “Company”) and Daiichi Sankyo Company, Limited (“Daiichi Sankyo”) entered into a letter agreement, dated July 29, 2017 (the “Termination Letter”) indicating that the parties have agreed to terminate the License Agreement by and between the Company and Daiichi Sankyo, dated January 23, 2012, (the “Agreement”), including without limitation, any and all memorandums of understanding and other agreements executed between the parties relating to the Company’s etanercept (Enbrel) biosimilar product candidate CHS-0214 (“CHS-0214”), pursuant to Section 12.3 of the Agreement. In the Termination Letter, the parties indicated that they are terminating the Agreement due to Daiichi Sankyo’s recent decision to discontinue development of CHS-0214 in Japan. The Company will not incur any early termination penalties as a result of the termination of the Agreement. As of July 31, 2017, Daiichi Sankyo beneficially owned 2,867,426 shares (approximately 5.58%) of the Company’s common stock.
