Samsung has wrapped up its fourth-quarter 2025 earnings report with results that underline just how powerful the current memory boom has become for the company. With demand tied closely to AI infrastructure and high-bandwidth memory ramping quickly across the industry, Samsung’s semiconductor and memory segments were the clear standouts—helping push both quarterly sales and profits sharply higher compared to a year ago.
For Q4 2025, Samsung posted quarterly sales of 93.8 trillion won (about $65.45 billion), a 24% jump year over year. Operating profit climbed even more dramatically, reaching 20.1 trillion won (around $14.05 billion), roughly tripling from the same period last year. Looking at the full year, total revenue came in at 333.6 trillion won (approximately $232.87 billion), up 11% year over year.
The biggest momentum came from semiconductors. Samsung’s semiconductor sales in Q4 hit 44 trillion won (about $30.74 billion), rising 46% year over year. Even more striking, semiconductor operating profit surged to 16.4 trillion won (roughly $11.46 billion), up 5.6 times compared to the year-ago quarter. Within that, the memory business delivered quarterly revenue of 37.1 trillion won (around $25.93 billion), soaring 62% year over year—an eye-catching indicator of just how central high-performance memory has become to today’s AI-driven market.
Samsung’s mobile business also grew, though profitability moved in the opposite direction. Quarterly mobile sales rose to 28.3 trillion won (about $19.78 billion), up 13% year over year. However, quarterly mobile operating profit slipped to 1.9 trillion won (around $1.33 billion), down 9.5% year over year, reflecting cost pressures that have been building across the smartphone space.
Looking ahead into early 2026, Samsung is setting up several important product and process milestones designed to strengthen its position in AI components and next-generation chips. The company says it plans to begin delivering mass products of HBM4 in Q1 2026, including an “industry-leading” 11.7Gbps version. That’s a notable figure, as reports suggest this throughput exceeds the 10Gbps operating speed requested by major AI accelerator customers.
Samsung is also leaning into storage opportunities tied to artificial intelligence, with an emphasis on scaling sales of high-performance TLC SSDs aimed at AI KV (Key-Value) SSD demand. On the imaging side, the company plans to broaden its lineup of 200MP camera sensors. And in foundry development, Samsung is focused on ramping its second-generation 2nm process—an area that’s becoming increasingly strategic as advanced packaging and cutting-edge nodes play larger roles in AI and high-performance computing.
Industry expectations suggest the shift from HBM3E to HBM4 could become a key market share battleground, and Samsung appears eager to capitalize. Reports indicate Samsung may begin supplying HBM4 to NVIDIA as early as February 2026 after passing qualification testing, with Samsung’s HBM4 performance potentially giving it an advantage in competing for major AI memory orders.
Still, Samsung is also preparing for near-term softness in certain segments. For Q1 2026, the company anticipates weaker smartphone demand due to seasonality, while also warning that memory supply and price dynamics could influence results.
Meanwhile, inside Samsung’s smartphone operation, rising costs may force a change that many buyers have managed to avoid in recent years: price increases. Samsung’s MX division is reportedly considering a price hike of 44,000 won (about $30) to 88,000 won (about $60) for the upcoming Galaxy S26 series in select markets, including South Korea. If it happens, it would mark a meaningful pivot from Samsung’s recent approach, which largely avoided flagship S-series price hikes over the past three years, aside from the Galaxy S24 Ultra. That pricing stability helped the Galaxy S25 line reach an estimated cumulative 3 million units roughly two months faster than its predecessor.
Overall, Samsung’s Q4 2025 earnings paint a clear picture: memory and semiconductors are powering the company’s profit engine, with HBM4 now positioned as a major growth lever for 2026. At the same time, smartphones remain a huge revenue driver, but one facing profitability pressure—setting up an interesting year where AI-focused components may increasingly define Samsung’s trajectory.
