Seoul, 29 January 2026 – Samsung Electronics Co. reported exceptionally strong financial results for the fourth quarter of 2025, with its semiconductor division posting record-breaking profitability as artificial intelligence-driven demand fuels a tight memory chip market.
Samsung’s operating profit for the October–December period surged to about 20 trillion won (roughly US$13.9 billion), more than triple the 6.49 trillion won logged in the year-ago quarter, marking the highest quarterly profit in the company’s history. Revenue also climbed to approximately 93 trillion won, a 24 per cent increase year-on-year, driven by robust sales of memory chips to data centre operators and AI infrastructure customers.
The company’s memory division, long a cornerstone of Samsung’s semiconductor business, benefited from soaring prices and strong demand for both conventional DRAM and advanced high-bandwidth memory (HBM) used in AI servers and accelerators. Analysts say constrained supply amid global structural shifts toward AI workloads has tightened market conditions and boosted chip pricing power.
Industry sources note that the current memory chip supply shortage is tied to a broader reallocation of semiconductor manufacturing capacity toward high-value, AI-centric products, a trend that has lifted contract prices for both DRAM and NAND flash memory and supported high margins. This dynamic has helped regional rivals such as SK Hynix and Micron Technology also report strong earnings in recent months.
Samsung’s profit surge comes as global demand for memory chips, particularly for AI data centres and advanced computing, far outpaces supply, a situation analysts describe as an ongoing market imbalance that could persist through 2026. The company is also progressing toward next-generation HBM4 production, expected to support cutting-edge AI processors later this year.
Despite the booming chip business, Samsung noted that other segments such as smartphones and displays faced pricing pressures, a reminder that strong memory demand is reshaping the company’s overall earnings mix. Nonetheless, the Q4 results underline how AI-led technology transformations are creating a more lucrative landscape for memory semiconductor manufacturers.
