SK Hynix's operating profit in the second quarter reached 60.54 trillion won, net profit was 93.82 trillion won, and sales were 79.32 trillion won. The profit increased significantly year-on-year but missed analysts' expectations. The company announced that HBM4 video memory has been mass-produced and shipped, and will expand its supply in the second half of the year, and sign long-term agreements with a number of customers to consolidate its leading position in the market. In the first half of 2026, SK Hynix's operating profit soared by 557%, with both revenue and profit hitting record highs. Driven by AI demand, the company accelerated the layout of high value-added products. The company also confirmed the signing of a cooperation agreement with Nvidia worth a total of US$500 billion to promote the mass production of HBM4 high-bandwidth memory. Despite the excellent performance, the operating profit in the second quarter was less than expected, which caused the stock price of U.S. stocks to rise after a sharp drop. South Korea's KOSPI index was fused for two consecutive days, Samsung Electronics also plummeted, and the memory chip sector as a whole was under pressure.
