On November 27, 2023, Mr. Darren Lui resigned from his position as Aptorum Group Limited?s Chief Executive Officer, to focus on his personal goals and pursuits. Mr. Ian Huen, one of the Company?s directors, who also served as the Company?s Chief Executive Officer from October 2017 until his prior resignation in June 2022, will step back into the role of Chief Executive Officer.

The Board is grateful for Mr. Lui and Dr. Cheng?s significant contribution to the Company over the years, and expresses its gratitude for their dedicated service to the Company during their tenures. The Board is excited to have Mr. Huen back as Chief Executive Officer and welcomes him to his new role.
