What Happened?

Shares of online platform company Coupang (NYSE: CPNG) fell 6.2% in the afternoon session after the company faced intense scrutiny as a major data breach exposed the personal information of 33.7 million customers, which led to the resignation of its CEO and police raids. 

The breach affected nearly two-thirds of South Korea’s population. In the wake of the incident, CEO Park Dae-jun resigned from his position. The situation intensified as police conducted raids at Coupang's Seoul headquarters, increasing scrutiny over the company's data security measures. The e-commerce giant also faced significant financial risk, with potential fines of up to $681 million under South Korea's Personal Information Protection Act. 

Adding to the company's challenges, founder Kim Bom-suk announced he would not attend a National Assembly hearing scheduled to address the massive data leak.
