Samsung Electronics has delivered a powerful signal that the artificial intelligence buildout is reshaping the memory-chip cycle, but its record quarter also raises a harder question for investors: whether extraordinary pricing power can survive the industry’s next wave of capacity spending.
The South Korean technology group said Thursday that revenue for the second quarter ended June 30 reached KRW 171.5 trillion, an all-time quarterly high and up 28% from the previous quarter. Operating profit climbed to KRW 89.5 trillion, also a record, while net profit reached KRW 71.6 trillion. A year earlier, Samsung reported KRW 74.6 trillion of sales and KRW 4.7 trillion of operating profit, showing how sharply the cycle has turned.
The source of the rebound was not hard to find. Samsung’s Device Solutions division, which houses its semiconductor operations, generated KRW 127.5 trillion of revenue and KRW 89.2 trillion of operating profit in the quarter. Its memory business posted record quarterly revenue and operating profit as server demand, high-bandwidth memory and enterprise storage absorbed supply quickly. Samsung said industry-wide price increases also contributed to the performance.
That combination is powerful because memory has historically been punished when producers overbuild and rewarded when supply tightens. AI has changed the current version of the cycle by making advanced DRAM, NAND and HBM less of a routine input and more of a bottleneck for data-center expansion. Samsung said demand in the second half should remain centered on servers, driven by continued AI infrastructure capital spending and broader adoption of agentic AI, while supply constraints are expected to continue despite efforts to increase production.
The market implication is more complicated than a simple earnings celebration. AP reported that Samsung and SK Hynix shares have been pressured this week even as both companies posted record results, reflecting concern over heavy manufacturing investment and competition from China. SK Hynix, Samsung’s domestic rival and another key supplier of AI memory, reported record results a day earlier, but its shares fell more than 9% after profit missed elevated expectations. When investors punish a company for record earnings, they are saying the bar has shifted from near-term profit to the durability of the AI infrastructure cycle.
Samsung’s own accounts show why that debate matters. The company said second-quarter capital expenditure was KRW 16.8 trillion, with KRW 15.4 trillion allocated to the chip division. It is expanding memory investments in Pyeongtaek and supporting the ramp-up of its Taylor, Texas, fab. AP reported that Samsung plans to begin construction of a second semiconductor fab in Taylor before the end of 2026, with production targeted for 2030, and that the company has secured long-term supply contracts with five major global data-center clients.
Longer contracts may help smooth the boom-bust pattern that has defined memory for decades. They can give customers better supply visibility and give Samsung more confidence before committing billions of dollars to fabs, equipment and advanced packaging. But they do not remove the central risk. If the largest cloud and AI companies are overestimating future demand, or if Chinese memory suppliers gain share faster than expected, today’s scarcity could turn into tomorrow’s margin pressure.
The quarter also showed that Samsung’s AI exposure is not evenly distributed across the group. Its Device eXperience division, covering mobile, networks, TVs and home appliances, posted KRW 48.0 trillion of revenue and an operating loss of KRW 0.8 trillion. The mobile and networks businesses reported an operating loss of KRW 0.7 trillion as component costs weighed on profitability. The same memory shortage helping Samsung’s chip division is raising costs inside parts of its own consumer-electronics business.
That internal split gives the results their real significance. Samsung is benefiting from one of the strongest semiconductor pricing environments in years, but it is also exposed to the inflationary side effects of that same shortage. Investors therefore need to judge not only whether Samsung can make enough AI chips, but whether it can allocate scarce capacity to the highest-return customers without weakening the rest of the franchise.
For now, the numbers support the bullish case. Samsung has record revenue, record profit and KRW 190.0 trillion of cash and related short-term financial assets at quarter-end. But the stock market’s caution is rational. The AI boom is turning memory producers into toll collectors for the digital economy, yet toll roads are expensive to build and dangerous to overbuild. Samsung’s record quarter proves the demand is real. The next test is whether management can convert scarcity into durable returns before the cycle turns again.
