I am very grateful to Obi and the Cerus Board of Directors for entrusting me with this extraordinary opportunity to serve."

Mr. Greenman joined Cerus in 1995 and has served as CEO for over 15 years. Under his leadership, Cerus transformed from a pre-clinical development company into a global commercial enterprise with product sales in over 40 countries.

"I am proud of the progress Cerus has made in advancing blood safety and availability," said Obi Greenman. "Having worked with Vivek for nearly a decade, I am confident that he is the right person to lead Cerus towards the goal of making INTERCEPT the global standard of care."

Added Greenman, "My goal has always been to establish Cerus as an enduring company. With four FDA product approvals in the past decade, a robust innovation pipeline, and a solid financial foundation, the company is well positioned to continue to lead the field of pathogen inactivation. As Executive Chair, I look forward to supporting Vivek as Cerus continues to deliver on its mission."
