SEOUL (Reuters) - South Korea's SK Hynix Inc on Thursday said fourth-quarter operating profit nearly tripled from a year earlier to a record high, beating market expectations on strong demand for memory chips.
The world's second-biggest memory chip maker behind Samsung Electronics Co Ltd said October-December profit was 4.5 trillion won ($4.23 billion). That compared with a 4.3 trillion won Thomson Reuters StarMine SmartEstimate from a survey of 12 analysts.
Revenue rose 69 percent to 9 trillion won.
