Someone sat outside the stores and counted.
On January 31, 2020, Muddy Waters Research published an anonymous 89-page report it had received and said it was short the stock. The report's method was almost insultingly simple: investigators — 92 full-time and over 1,400 part-time staff — recorded more than 11,000 hours of store traffic video across hundreds of store-days and collected over 25,000 customer receipts. Their count implied items per store per day were inflated by at least 69% in Q3 2019 and 88% in Q4 2019. Luckin called the report "misleading and false."
Nine weeks later, the company confirmed the substance. On April 2, 2020, Luckin disclosed that a special committee investigation had found that COO Jian Liu and several employees reporting to him had fabricated transactions beginning in Q2 2019, with aggregate fabricated sales of around RMB 2.2 billion through Q4 2019 — roughly $310 million. The SEC's later complaint detailed the mechanics: false retail sales run through related parties in three separate purchasing schemes, expenses inflated by more than $190 million to make the fake revenue look plausibly costly, a fake operations database, and altered accounting and bank records.
The fraud was discovered not by the auditor, the audit committee, or the underwriters — but by short sellers with camcorders, counting cups in parking lots.
This is the detail every CFO should sit with. Luckin's reported growth rested almost entirely on internally generated operating data. When someone finally corroborated that data against something external — physical foot traffic, actual receipts — the story collapsed in a single trading day. The shares fell about 76% on the April 2 disclosure. The endgame ran on rails from there.
