Samsung Shares Fall Despite Better-Than-Expected Earnings
SEOUL—Samsung Electronics’ preliminary second-quarter numbers beat analyst expectations, and its shares fell as much as 5% on the Korea Exchange on Tuesday. The selloff, coming after months of gains driven by artificial-intelligence chip demand, rippled through memory-chip rivals across the region and split Samsung’s own supplier network in two.
The company said preliminary revenue for the quarter came in at 89.4 trillion won, above the 84.2 trillion won that analysts had expected. Full results, including operating profit, are due later this month.
Investors sold the stock anyway. The pattern has become familiar in the memory-chip trade: good news, then profit-taking, as traders said the shares had already priced in several quarters of growth. Samsung’s stock had been among the biggest beneficiaries of the AI rally in Seoul, and Tuesday’s move looked more like portfolio rebalancing than a verdict on the business.
The reaction dragged down SK Hynix, Samsung’s closest memory rival, whose shares fell as much as 2.4% before paring losses. In Tokyo, memory maker Kioxia dropped as much as 4.9%. The moves rippled through an entire region of chip suppliers, though the direction of the damage varied sharply.
The divergence among suppliers told a sharper story. In Seoul, companies that do much of their business with Samsung rose: Samsung SDS climbed as much as 6.3%, while Eugene Technology gained 6.4%, Wonik IPS 3.5% and Global Standard Technology 2.6%. The last three derive more than half of their sales from Samsung Electronics, analysts noted.
In Tokyo, the picture reversed. Lasertec fell 4.1%, Kokusai Electric 3.3%, Micronics Japan 3% and Advantest 1.5%, equipment makers whose fortunes track the broader chip-capital-spending cycle rather than any single customer’s output.
The split makes sense, traders said. Samsung’s better-than-expected revenue points to strong demand for memory chips, especially high-bandwidth memory sold into AI data centers. Korean suppliers, whose order books move with Samsung’s output, read the numbers as good news. Japanese equipment makers, by contrast, had rallied hard in recent months on AI optimism and were due for a pullback.
The results land in the middle of a memory boom that has reshaped the industry. AI workloads devour memory bandwidth, pushing prices of DRAM and NAND higher and filling the order books of Samsung, SK Hynix and other producers. High-bandwidth memory, the specialized chips that sit next to AI accelerators, has become one of the most sought-after products in the semiconductor world, and Samsung has spent heavily to catch up with SK Hynix in that segment.
The question hanging over the sector is how long the cycle lasts and how much of it is already in the share prices. Memory is a famously cyclical business, and companies that make record profits in an upcycle have historically handed much of it back when supply catches up with demand. This cycle is different in one respect: the demand is tied to AI computing, which is still in its early expansion, but the manufacturing response, new fabs and new capacity, takes years to arrive.
Samsung’s preliminary figures also feed a broader market debate about whether the AI-driven rally in Asian technology stocks has run too far. The company’s shares had climbed steadily through the spring, and Tuesday’s dip suggested some investors wanted to bank gains before the full earnings report lands. Fund flows across the region have favored chip names all year, and any wobble in the group’s leaders tends to spread.
The full report later this month will show whether the strong top line translated into profit. Analysts expect operating profit to have grown sharply year over year, driven by memory pricing, though costs tied to advanced chipmaking and capacity expansion will take a share. Samsung is also running its foundry business, which makes chips for other companies, at a time when that market has been slower to recover.
The supplier split also reflects a structural difference between the two markets. South Korea’s chip ecosystem is built around Samsung and SK Hynix, and suppliers there live and die with the two giants’ output plans. Japan’s equipment makers sell to every foundry and memory producer in the world, so their stocks trade more on the global capital-spending cycle than on any single earnings report.
For Samsung itself, the quarter caps a stretch in which the company has tried to rebuild credibility with investors. It has been expanding production of high-bandwidth memory, courting AI customers with customized chip packages, and promising to return more cash to shareholders. The preliminary numbers suggest the strategy is working at the revenue line; the share reaction suggests investors want proof it can hold over a full cycle.
For the memory industry, the message is mixed. Demand looks strong, but the market’s reaction shows how much of that strength is already in the price. The coming weeks, as Samsung, SK Hynix and others report full results, will test whether the sector can hold its gains or whether the rally was, in part, borrowed from the future.
