Luckin Coffee Receives Delisting Notice from Nasdaq for Failure to File its Annual Report

BEIJING, June 23, 2020 (GLOBE NEWSWIRE) — Luckin Coffee Inc. (the “Company”) (NASDAQ: LK) today announced that on June 17, 2020, it received an additional written notice (the “Notice”) from the Listing Qualifications Staff of the Nasdaq Stock Market LLC (“Nasdaq”) indicating that the Company’s failure to file its Form 20-F for the period ended December 31, 2019 (the “Annual Report”) serves as an additional basis for delisting the Company’s securities from the Nasdaq pursuant to Nasdaq Listing Rule 5250(c)(1). This Notice is in addition to the two bases cited in the written notice issued by the Listing Qualifications Staff as disclosed by the Company on May 19, 2020.

The Company has been working diligently to explore possible ways to file the Annual Report as soon as possible. However, the Company has not been able to file the Annual Report due to the impact of the delayed financial statement preparation process caused by COVID-19 and the pendency of the previously disclosed internal investigation.
