The world's largest memory chip, smartphone and TV maker estimated an operating profit of 9.1 trillion won ($6.78 billion) for the three months ended Sept. 30, versus a 10.3 trillion won LSEG SmartEstimate.
That would compare with 2.43 trillion won in the same period a year earlier and 10.44 trillion won in the preceding quarter.
Samsung has been the world's biggest memory chipmaker for three decades but it increasingly faces competition in both conventional and advanced chips.
High-margin chips used in AI servers are driving a recovery in the chip market after a post-pandemic downturn last year. Still, Samsung has lagged behind SK Hynix (000660.KS) in supplying high-bandwidth memory (HBM) chips to AI leader Nvidia (NVDA.O).
Demand remains lacklustre for commodity chips used in PCs and smartphones upon which Samsung relies more than rivals, analysts said.
