Luckin Coffee Announces Appointments of Two Independent Directors

BEIJING, China, March 27, 2020 (GLOBE NEWSWIRE) — Luckin Coffee Inc. (“Luckin Coffee” or the “Company”) (NASDAQ: LK), a pioneer of a technology-driven new retail model to provide coffee and other products of high quality, high affordability, and high convenience to customers, today announced appointments of two independent directors to the Company’s Board of Directors (the “Board”). The Board welcomes the appointment of Mr. Tianruo Pu and Mr. Wai Yuen Chong as independent directors to the Board and members of its Audit Committee, effective March 27, 2020. As the Securities Exchange Act of 1934 requires that the Audit Committee shall consist of only independent directors after one year from the date of effectiveness of the  registration statement for Company’s IPO, Mr. Erhai Liu has stepped down as a member of the Audit Committee and the current Audit Committee consists of Mr. Sean Shao, Mr. Thomas P. Meier, Mr. Tianruo Pu and Mr. Wai Yuen Chong, with Mr. Sean Shao serving as its chairman.

Mr. Tianruo Pu has more than 20 years of work experience in finance and accounting. He currently serves as an independent director and audit committee’s chairman/member in various listed companies, including OneConnect Financial Technology Co., Ltd., Autohome Inc., Renren Inc., Kaixin Auto Holdings and 3SBio Inc. Mr. Pu served as the chief financial officer of Zhaopin Ltd from 2016 to 2018 and UTStarcom from 2012 to 2014.

Mr. Wai Yuen Chong has more than 30 years’ management experience in areas including supply chain, logistics, IT and manufacturing operation. He currently serves several roles in Charoen Pokphand Group, including the chief executive officer of Bake House (Shanghai) Catering Management Co. Ltd. and CP Mart Club (Suzhou) Co. Ltd., the subsidiaries of Charoen Pokphand Group. Before joining Charoen Pokphand Group, Mr. Chong worked at Starbucks China/Asia Pacific and Yum! Brands China as a senior executive.
