On March 4, 2019, Cary Mack, a director of Western Alliance Bancorporation, informed the Board of Directors that he did not wish to be re-nominated as director of the company at the upcoming 2019 Annual Meeting of the Shareholders. Also, on March 6, 2019, director William S. Boyd advised the Board that he would be retiring effective as of the Annual Meeting. Neither director declined to stand for re-election because of a disagreement with the company on any matter relating to the company’s operations, policies or practices. In connection with these notifications, the Board determined to fix the number of directors at thirteen, effective as of the date of the Annual Meeting, and selected Adriane McFetridge, Director of Engineering - Subscription Platform for Netflix Inc., as a new director nominee. Ms. McFetridge will contribute to the skills and gender diversity of the Board in accordance with the company’s director selection priorities. The Board also determined to appoint Mr. Boyd to the position of Director Emeritus effective as of the date of the Company's Annual Meeting.
