Coupang Reports Q4 2025 Earnings Amid 33M Account Data Breach, Stock Slumps

Coupang Inc. (CPNG) revealed a significant data incident during its Q4 2025 earnings report, with security analysts confirming unauthorized access to personal data from approximately 33 million user accounts. The breach, which occurred in late November 2025, compromised sensitive information including names, email addresses, phone numbers, and hashed passwords. While no financial data or payment details were exposed, the scale of the incident has raised serious concerns about data protection practices in the consumer technology sector. The company reported adjusted net income of $142 million for the quarter, a 12% decrease year-over-year, with revenue reaching $2.3 billion, slightly below analysts’ consensus estimate of $2.35 billion. Management cited the data incident as a key factor in the earnings miss, noting increased costs related to forensic investigations, regulatory compliance, and customer support. Coupang also announced a $65 million reserve for potential fines and legal settlements, reflecting heightened scrutiny from global data protection authorities. Shares of CPNG dropped 18% in after-hours trading following the announcement, outpacing the broader market’s reaction. The Nasdaq-100 index declined 2.1%, while the CBOE Volatility Index (^VIX) spiked to 27.4, signaling elevated market risk. Competitors Amazon (AMZN) and Shopify (SHOP) saw modest declines of 1.7% and 1.2%, respectively, suggesting broader investor caution in the e-commerce space amid growing cybersecurity risks. Regulatory bodies in South Korea, the European Union, and the United States are expected to launch investigations into the breach, with potential penalties under GDPR and Korea’s Personal Information Protection Act. The incident underscores the increasing vulnerability of digital platforms handling vast consumer datasets and highlights the financial and operational risks tied to cyber incidents in high-growth tech markets.
