Yves has taken significant steps to position Calyxt on track for its first commercial launch. I continue to be impressed by the way that he has been immediately adopted by the team and motivated all to make Calyxt a great success. Yves and Jim will work closely together on an efficient transition. Yves will also remain a member of the Board of Directors of the Company,” added Dr. André Choulika.

“I am honored to take on the role as Calyxt’s next CEO as the Company has the potential to become the leader when it comes to healthier food choices for consumers,” added Jim Blome. “I look forward to working closely with the Board, management team and talented and committed employees to leverage all of Calyxt’s truly unique capabilities and deliver nutritionally rich, cost-effective food products. I have made it my mission to always execute with purpose, putting the consumer first in everything that we do.”
