Item 5.02. Departure of Directors or Certain Officers; Election of Directors; Appointment of Certain Officers; Compensatory Arrangements of Certain Officers.

On December 21, 2017, the Board of Directors (the “Board”) of Global Blood Therapeutics, Inc. (the “Company”) appointed Wendy Yarno to the Board as a Class II director. Ms. Yarno was appointed to a newly created vacancy resulting from an increase in the size of the Board from eight (8) to nine (9) directors. She will serve on the Board’s compensation committee.

Ms. Yarno, age 63, retired in September 2008 from Merck & Co., Inc. following a 26-year career there in commercial and human resource positions of increasing seniority, most recently as Chief Marketing Officer before she retired. Prior to this role, she served as General Manager for Merck’s Cardiovascular/Metabolic United States Business Unit and as Senior Vice President, Human Resources. From 2010 to 2011, Ms. Yarno was the Chief Marketing Officer of HemoShear LLC, a biotechnology research company. Ms. Yarno currently serves on the boards of directors of the biopharmaceuticals companies Alder BioPharmaceuticals, Inc., MyoKardia, Inc. and Inovio Pharmaceuticals, Inc., and Aratana Therapeutics, Inc., a pet therapeutics company. Ms. Yarno previously served as member of the board of directors of St. Jude Medical, Inc., a medical device company, from 2002 until January 2017 when St. Jude Medical was acquired by Abbott Laboratories; Medivation, Inc., a biopharmaceutical company, from April 2013 until September 2016 when Medivation was acquired by Pfizer Inc.; and Durata Therapeutics, Inc., a pharmaceutical company, from August 2014 until November 2014 when Durata was acquired by Actavis plc. Ms. Yarno received an M.B.A. from Temple University, Fox School of Business, and a B.S. in business administration from Portland State University.

Upon her appointment to the Board, Ms. Yarno was granted an option to purchase 30,000 shares of the Company’s Common Stock at an exercise price equal to the closing price of the Company’s common stock on the Nasdaq Global Select Market on December 21, 2017, which will vest in equal monthly installments during the three years following the effective date of her appointment to the Board, subject to Ms. Yarno’s continued service on the Board.

Ms. Yarno is not a party to any transaction with the Company that would require disclosure under Item 404(a) of Regulation S-K, and there are no arrangements or understandings between Ms. Yarno, on the one hand, and any other persons, on the other hand, pursuant to which Ms. Yarno was selected as a director.
