Coupang posts record sales but Q4 profit collapses 97% after data breach. South Korea's e-commerce giant reported annual revenue of 49.1 trillion won, up 14% year-over-year, with full-year operating profit reaching 679 billion won. However, the December personal data breach severely impacted fourth-quarter results, with operating profit plummeting to just 11.5 billion won from 435.3 billion won a year earlier. The company's operating margin narrowed to 0.09% in Q4, and it posted a quarterly net loss of 37.7 billion won. CEO Kim Beom-seok acknowledged the breach's impact on customer trust and revenue growth. Despite the quarterly setback, management indicated recovery began in the first quarter and the breach's impact has stabilized.
