Investor Alert: Class Action Against Coupang, Inc.

On January 22, 2026, Pomerantz LLP announced the filing of a class action lawsuit against Coupang, Inc., a leading South Korean e-commerce platform listed on NYSE under the ticker CPNG. This legal action comes in the wake of a significant data breach that exposed the personal information of approximately 33.7 million customers, raising serious concerns over the company’s security practices and potential wrongdoing by its management.

The class action aims to secure justice for investors who faced losses due to alleged securities fraud or other unlawful business practices. Investors who acquired Coupang securities during the specified Class Period are encouraged to act before the deadline of February 17, 2026, to seek recognition as Lead Plaintiff. Interested shareholders can reach out to Danielle Peyton at Pomerantz LLP for more details.

Background on the Data Breach

The controversy began when a Reuters article on November 30, 2025, reported that Coupang had publicly apologized for the breach. It indicated that a significant amount of sensitive customer data was accessed unauthorizedly, triggering an emergency meeting from the South Korean government to investigate potential breaches of personal information protection laws. Following this revelation, Coupang's stock plummeted by $1.51 per share, marking a notable decline of 5.36% on December 1, 2025.

The situation worsened when, on December 10, 2025, the New York Times disclosed that Coupang's CEO had resigned in response to the data breach fallout. This led to further stock depreciation, falling an additional $0.87 per share, or 3.2%, just days after the CEO’s resignation. The implications of the breach became even direr when on December 16, the company filed an official report with the U.S. Securities and Exchange Commission, confirming that a former employee had purportedly gained access to a wide array of personal information, including names, phone numbers, and details of customer orders. The stock price subsequently dropped yet again, settling at $22.72 per share following this news.
