Samsung Electronics forecast operating profit of 107.4 trillion won for the July-September quarter, a figure that would mark the highest quarterly earnings ever recorded by a technology company. The projection, disclosed in a regulatory filing on October 8, exceeds the LSEG SmartEstimate of 106.1 trillion won and represents nearly a nine-fold increase from the same period last year.
The company attributed the surge to strong demand for memory chips used in artificial intelligence infrastructure. Tight supplies of conventional DRAM and NAND, combined with rising need for high-bandwidth memory (HBM), have pushed prices upward and boosted margins for Samsung’s semiconductor division. Analysts expect the imbalance between supply and demand to persist through 2028, though rising costs, competition from Chinese manufacturers, and potential U.S. semiconductor tariffs could temper future growth.
Memory chip sales are projected to account for the bulk of the earnings improvement. Third-quarter revenue is expected to rise 127% year-over-year to 195 trillion won. Samsung will release detailed financial results, including segment-level performance, on October 29. Its shares edged up 0.3% in early trading, outperforming a slight decline in the KOSPI index.
Analysts note that Samsung’s HBM bit shipments likely grew close to 50% quarter-over-quarter in the third quarter. U.S. rival Micron also forecast quarterly revenue above estimates, citing a tightening memory market beyond 2027. While the memory boom benefits Samsung’s chip business, higher component prices are increasing costs for its smartphone and consumer electronics divisions, pressuring margins in those segments.
Samsung’s contract chipmaking business is expected to remain unprofitable in the near term due to fixed costs and limited utilization rates. However, utilization is projected to improve as demand for advanced manufacturing processes grows. The company is working to narrow the gap with TSMC in this area. AMD’s CEO has indicated ongoing interest in exploring partnerships with Samsung in both memory and foundry sectors.
Chinese memory manufacturers are advancing but face constraints from U.S. export controls on advanced equipment and the long timeline required to build new production capacity. Any future U.S. tariffs could further influence global supply dynamics, though analysts note it would take several years for new U.S. facilities to meaningfully impact global memory supply.
The weakening South Korean won may offset some revenue gains from overseas sales when converted into local currency. While the current environment supports strong earnings, the sustainability of this trend depends on how quickly supply can expand and how demand for AI-driven memory usage evolves.
