SK Hynix's third-quarter profit surged more than 7-fold, beating expectations.

South Korean chipmaker SK Hynix announced on Wednesday that its quarterly operating profit surged more than sevenfold to a record high, exceeding market expectations, driven by rising memory chip prices amid sustained demand for artificial intelligence infrastructure. The Nvidia supplier reported operating profit of 83.3 trillion won for the July-September period, compared with 11.4 trillion won a year earlier. Market expectations had been 76.7 trillion won, a figure that places greater weight on estimates from analysts with more stable forecasting accuracy.
