SEOUL (Reuters) – Samsung Electronics Co Ltd on Friday said its October-December operating profit likely jumped 52% on-year to its highest fourth-quarter profit in four years, helped by solid demand for server memory chips and higher margins in chip contract manufacturing.

The world’s largest memory chip and smartphone maker estimated fourth-quarter profit at 13.8 trillion won ($11.5 billion), versus a Refinitiv SmartEstimate of 15.2 trillion won.
