The multiple class-action lawsuits against Coupang, coupled with the data breach affecting millions of customers and the CEO's resignation, are expected to negatively impact Coupang's stock price and investor confidence. The legal proceedings and potential compensation plans could lead to significant financial liabilities for Coupang, while law firms like Rosen Law Firm, Levi & Korsinsky, and Hagens Berman stand to benefit from representing aggrieved shareholders.
Coupang, an e-commerce company, is facing multiple class-action lawsuits from investors, led by firms such as Rosen Law Firm, Levi & Korsinsky, and Hagens Berman. These lawsuits allege that Coupang made false and misleading statements and failed to disclose inadequate cybersecurity protocols that allowed a former employee to access sensitive customer information for nearly six months without detection. The data breach, which affected approximately 33.7 million customer accounts, was reportedly not reported to the United States — United States Securities and Exchange Commission in a timely manner. The fallout from this event includes a reported $1.2 billion compensation plan, the resignation of Coupang CEO Park Dae-jun, and the appointment of Harold Rogers as interim CEO. Korean regulators have also initiated investigations into the incident. Investors who purchased Coupang securities between August 6, 2025, and December 16, 2025 (or May 7, 2025, and December 16, 2025, according to some firms) have until February 17, 2026, to seek lead plaintiff status in the lawsuits.
