Samsung Electronics expects earnings to have rebounded strongly for the third quarter on a recovery in its flagship semiconductor segment, beating market expectations.

The South Korean technology giant said in preliminary quarterly results Tuesday that its operating profit likely reached 12.1 trillion won, equivalent to $8.48 billion, for the July-September period, the highest in three years.

That would be up 32% from a year earlier and more than double the previous quarter's figure, topping the 9.742 trillion won consensus estimate of analysts in a FactSet poll.

Quarterly revenue likely rose 8.7%, to a record 86 trillion won, Samsung said. That was also above market expectations.

Shares in Samsung closed 1.2% lower, at 93,300 won, on Monday ahead of the earnings guidance, snapping a three-session winning streak.

The stock remains more than 75% higher this year, buoyed by expectations that the artificial-intelligence boom will drive chip demand for years to come.

Samsung gave no further earnings details. It is scheduled to release full quarterly results later this month.
