SEOUL, April 7 (Reuters) - Tech giant Samsung Electronics Co Ltd estimated on Friday its first-quarter operating profit rose 48 percent from a year earlier, beating expectations as strong memory chip prices likely padded margins.
Samsung, in a regulatory filing, said its January-March profit was likely 9.9 trillion won ($8.76 billion), compared with an average forecast of 9.4 trillion won from a Thomson Reuters survey of 18 analysts.
Revenue likely rose 0.4 percent from a year earlier to 50 trillion won, Samsung said.
The company did not elaborate on its performance and will disclose detailed earnings in late April. ($1 = 1,130.0900 won) (Reporting by Se Young Lee; Editing by Stephen Coates)
