Change of Independent Director


On December 9, 2023, Mr. Stanley Yi Chang (“Mr. Chang”) notified the Company of his resignation as an independent director of the Company as well as a member of the Compensation Committee (the “Compensation Committee”), a member of the Nominating and Corporate Governance Committee (the “Nominating and Corporate Governance Committee”) and the chairperson of the Audit Committee (the “Audit Committee”), effective from December 9, 2023. Mr. Chang has advised the Company that his resignation was due to personal reasons.


To fill in the vacancy created by Mr. Chang’s resignation, on December 9, 2023, the Nominating and Corporate Governance Committee recommended, and the Company’s board of directors (the “Board”) approved, the appointment of Ms. Rachel Yu (“Ms. Yu”) to serve as an independent director of the Company, effective from December 9, 2023.


Ms. Rachel Yu, aged 49, has served as a partner at Oceanpine Capital’s healthcare practice since May 2021, where she is responsible for formulating the overall investment strategies in the healthcare sector and taking day-to-day principal leadership responsibility in financial and operational management of financial team, investment team and portfolio companies. Prior to that, she was a partner at China Renaissance Group, where she worked from 2014 to 2021 and took the principal responsibility in deal sourcing, and conducting due diligence on investment targets, including financial and operational data, financial models and valuation and compliance. From 2012 to 2014, Ms. Yu served as vice president/head of China healthcare research at Gerson Lehman Group. Prior to that, Ms. Yu worked as an equity analyst at Maxim Group, Rodman & Renshaw, and Deutsche Bank Securities. Ms. Yu received her BSc from Guangdong Pharmaceutical University, her MSc from The University of Missouri School of Medicine, and her MBA from the University of Chicago Booth School of Business with concentrations in finance, accounting and entrepreneurship.


There are no family relationships between Ms. Yu and any director or executive officer of the Company. To the best knowledge of the Company, there is no understanding or arrangement between Ms. Yu and any other person pursuant to which she was appointed as the Company’s independent director. Additionally, there have been no transactions in the past two years to which the Company or any of its subsidiaries or affiliates was or is to be a party, in which Ms. Yu had, or will have, a direct or indirect material interest.


Appointment of Interim Chairperson


The Board, acting upon an ad hoc motion raised at a Board meeting, appointed Dr. Ajit Shetty, an independent director of the Company, as an interim Chairperson of the Board for a six-month period to replace Mr. Yi Zhang, the current Chairperson of the Board, effective from December 9, 2023.
