Samsung Electronics is expected to miss its fourth-quarter profit expectations, with forecasts predicting an operating profit of 6.5 trillion won, below the anticipated 7.7 trillion won. Analysts attribute this shortfall to struggles in supplying high-end memory chips to Nvidia and rising R&D costs. Despite a year-on-year profit increase, sequentially it reflects a decline. Competitor SK Hynix is forecasted to achieve record profits, highlighting Samsung's challenges in the memory chip market.
