The company also announced a monstrous capital investment plan to increase chip production and higher shareholder dividends as the world's largest chipmaker basks in an unprecedented boom in the memory chip industry that helped it overcome a crisis in its leadership.
The South Korean company's July-September net income surged 150 percent to 11 trillion won (USD 9.8 billion), compared with 4.4 trillion won a year earlier.
The result beats analysts' consensus of 10.9 trillion won, according to financial data provider FactSet.
Samsung, the world's largest maker of smartphones, has continued its record-breaking earnings streak thanks to a global boom in memory chips, even as its de facto chief was sentenced to five years in prison on a conviction for bribery.
To respond to a surge in demand for memory chips that power data centers and mobile devices, Samsung is spending 46.2 trillion won (USD 41.1 billion) in capital expenditure this year, including 29.5 trillion won to increase output of chips. That is nearly twice as large as Samsung's last year's capital spending of 25.5 trillion won.
