Seoul: U.S.-listed e-commerce giant Coupang Inc. said Wednesday it swung to a net loss in the first quarter amid fallout from a massive customer data breach in South Korea. The company posted a net deficit of $266 million in the January-March period, compared with a net profit of $114 million a year earlier, Coupang said in a press release. According to Yonhap News Agency, Coupang also turned to an operating loss of $242 million in the first quarter from a net profit of $154 million a year ago, while sales rose 8 percent on year to $8.5 billion. Coupang Korea, which generates more than 90 percent of the group's total revenue, has faced a public backlash following disclosure of a data breach in November 2025 involving some 33.6 million customers.
