Coupang (CPNG) stock saw a modest decline following news that interim CEO Harold Rogers has left South Korea amid a major data breach investigation. Rogers, who oversaw the company’s operations during a challenging period, departed on December 31 shortly after appearing at a parliamentary hearing addressing the breach affecting 33 million users.

Investors reacted cautiously, worried about the potential impact of regulatory scrutiny and leadership uncertainty on the e-commerce giant’s performance.

Authorities had summoned Rogers for questioning on January 5, but he did not attend, prompting the Seoul Metropolitan Police Agency to request notification from the Ministry of Justice when he returns. A travel ban could be enforced to ensure his compliance with ongoing inquiries. Coupang, however, stated that Rogers left for a pre-arranged business commitment and affirmed his willingness to cooperate with the investigation.

Massive Breach Impacts Millions

The security lapse has exposed the personal information of 33 million South Korean users, making it one of the largest breaches in the country’s recent history. By comparison, Meta’s Facebook and Instagram breach affected fewer than a million users but resulted in a $15.67 million fine.

Under South Korea’s Personal Information Protection Act (PIPA), penalties are capped at a percentage of annual revenues linked to the violation.

Affected users may be eligible for statutory damages of up to 3 million Korean won per person if gross negligence or intent is proven. The breach has renewed discussions on the adequacy of local privacy protections, especially given the scale of modern e-commerce operations.

Analysts note that while fines may remain modest relative to the company’s size, reputational damage and regulatory scrutiny could weigh on investor sentiment.

Regulatory Response and Legal Risks

Police are also investigating whether Rogers’ testimony before the parliamentary committee was fully accurate, following a complaint alleging violations of testimony laws. This adds another layer of legal risk for the company’s leadership, as authorities evaluate compliance with both PIPA and parliamentary procedures.

The Personal Information Protection Commission (PIPC) can mandate security improvements, ensure proper handling of data requests, and enforce technical safeguards to prevent similar incidents. South Korean authorities have signaled that companies may face stricter requirements on proactive cybersecurity planning and internal controls moving forward. Analysts expect the breach to set a precedent for regulatory enforcement in high-profile data incidents.

Cybersecurity Industry Sees Opportunity

South Korea’s 72-hour notification rule, which requires alerting affected users and regulators promptly, has created demand for breach response services. Vendors offering vulnerability assessments, load balancing, identity monitoring, and CISO advisory services are likely to see increased interest following the Coupang incident.

Credit monitoring and identity theft protection services may also gain traction, as users can claim statutory damages without proving actual loss if negligence is established. Experts say this breach illustrates both the risks of lax cybersecurity and the business opportunities for companies providing protective and response solutions.
