2. -- Samsung Electronics Co. (SSNLF) confirmed its most profitable quarter on record Tuesday and said it would double the amount of cash it returns to shareholders and boost its capital spending plans as it looks to maintain its lead in the surging global memory chip market.
The world's biggest chip and smartphone maker said operating profit for the three months ended in September was 14.53 trillion Korean won ($12.91 billion), a 23.4% increase from the same period last year, on sales of about 62 trillion Korean won.
Samsung also pledged to return 26 billion Korean won to shareholders over the next three years, doubling its annual dividend to 9.6 trillion Korean won. That will put around 50% of the group's free cash flow back into the hands of investors.
The company also said capex for the full year will be increased to a record 46.2 trillion Korean won as it plans new factory, assembly and storage facilities to take advantage of the surge in global chip demand.
CEO Kwon Oh-Hyun, heir apparent to the incarcerated former chairman, Jay Y. Lee, said earlier this month he would step down in March after more than three decades at Samsung to make room for what he called "a new spirit and young leadership." Samsung announced on Tuesday the promotion of three executives as joint CEOs.
