Hagens Berman Investigating Coupang, Inc. Over Data Breach Claims

Hagens Berman, a national law firm representing the rights of shareholders, has recently announced its investigation into Coupang, Inc. (NYSE: CPNG) due to serious allegations regarding a data breach and potential misinformation provided to investors. The claims suggest that Coupang may have failed to disclose crucial details regarding its cybersecurity practices and the extent of a data breach that reportedly affected millions of customers.

The firm has set a deadline of February 17, 2026, for lead plaintiffs to step forward in the pending class action lawsuit. Investors who acquired Coupang shares between May 7, 2025, and December 16, 2025, and suffered financial losses during this period are particularly encouraged to contact Hagens Berman.

Allegations of Misrepresentation

The heart of the complaint lies in Coupang's assurances to investors regarding its cybersecurity measures. The lawsuit alleges that Coupang publicly claimed to have effective technical and administrative safeguards in place to protect users' personal data from unauthorized access. However, it appears that these assurances may have been misleading. The allegations grew more serious following a disturbing revelation revealed on November 29, 2025, when Coupang announced a breach of its internal systems that compromised personal data from about 33.7 million customer accounts in South Korea.

Upon investigation, it was found that unauthorized access to this sensitive information reportedly began back in June 2025 and was carried out through overseas servers, raising questions about Coupang's cybersecurity protocols.

Executive Changes and Delayed Disclosures

Additionally, on December 10, 2025, Coupang's CEO, Park Dae-joon, resigned amid the fallout from the data breach, and the company's Chief Administrative Officer, Harold Rogers, was appointed as the interim CEO. The timing of these changes suggests increasing concerns about the management's accountability in handling the breach.

The investigation revealed that Coupang was aware of the breach as early as November 18, 2025, but did not disclose this information to the public until almost a month later. Such delays could potentially indicate a failure to comply with investor transparency laws and might have contributed to losses incurred by shareholders when the news eventually broke.

Compensation and Regulatory Action

In an effort to restore trust following the breach revelations, Coupang announced a compensation plan worth approximately 1.685 trillion won (which translates to over $1 billion) on December 29, 2025. Furthermore, Korean regulatory authorities have initiated investigations, and Coupang has committed to fully cooperating with these inquiries.

Future Implications

Hagens Berman is currently investigating whether Coupang was aware that its cybersecurity measures were inadequate but opted not to inform shareholders effectively. In light of these events, potential plaintiffs are encouraged to gather any pertinent information that may contribute to the case. The firm notes that whistleblowers with significant information regarding the breach are also welcome to reach out for assistance.

This investigation emphasizes the ongoing importance of corporate accountability and the legal responsibilities that publicly traded companies have towards their investors. For Coupang, these developments could have lasting ramifications, impacting its market position and investor trust.
