Coupang Inc.’s stock price on the NYSE closed at US$21.13 on January 18, 2026 down about 25% from US$28.20 before a large-scale personal data leak was disclosed in late November.

The company’s market capitalization has decreased by over 18 trillion won (US$14 billion) since late November, dropping from around US$51.4 billion to US$38.6 billion.

Several global investment banks, including Morgan Stanley and Citigroup, have issued negative outlooks, citing regulatory risks and increased costs related to cybersecurity and compensation measures.

The company disclosed its investigation results into the data breach to the US SEC last month, prompting concerns over potential sanctions and legal risks.

Domestic and US class-action lawsuits have been filed against Coupang over management and disclosure issues.
