Samsung Electronics on Friday said its second-quarter operating profit likely rose 5.2 percent from a year earlier, missing analyst estimates.
Its sluggish mobile business pressured strong margins from its chip sales, analysts have said.
Samsung, in a regulatory filing, said April-June profit was likely 14.8 trillion won ($13.2 billion), below the 14.9 trillion won average of 18 analyst estimates in a Thomson Reuters poll.
Revenue likely fell 4.9 percent from a year earlier to 58 trillion won.
The firm did not elaborate on its performance and will disclose detailed earnings in late July.
