Samsung Electronics, the world's largest memory chipmaker, announced a remarkable 19-fold increase in its second-quarter operating profit, reaching an estimated 89.4 trillion won (approximately $58.4 billion). This staggering growth, up from 4.7 trillion won in the same period last year, was largely driven by soaring memory chip prices amidst robust demand for artificial intelligence (AI) technologies.
However, despite these blockbuster results, Samsung's stock experienced a significant decline, falling as much as 9% in morning trading. This downturn mirrored a broader market reaction, with rival SK Hynix also seeing shares drop by up to 7.3%, collectively weighing heavily on South Korea's benchmark KOSPI index.
Why Shares Fell Despite Record Earnings
Market analysts suggest several factors contributed to the unexpected share slump. Many investors had already priced in exceptionally strong earnings following Samsung's recent rally, leading to heightened expectations. Some even hoped for operating profit to surpass the 90 trillion won mark, even after accounting for substantial employee bonus expenses tied to a wage agreement reached in May.
Another key concern driving selling pressure was the long-term outlook for AI infrastructure spending. Investors are questioning whether the current AI-driven semiconductor boom can be sustained indefinitely, leading to caution despite the impressive quarterly figures.
AI Investment Outlook and Future Risks
Samsung's strong performance was bolstered by a sharp increase in memory chip prices, with AI-related demand expanding beyond high-bandwidth memory (HBM) chips to include conventional DRAM and NAND memory products. Citi Research estimated average selling prices for DRAM rose 44% quarter-on-quarter, while NAND prices increased 53% during the second quarter. Furthermore, customers are increasingly signing long-term supply agreements, indicating expectations of prolonged elevated memory prices.
Looking ahead, analysts identify a potential slowdown in AI infrastructure spending as the biggest challenge for the semiconductor industry. Possible delays in building AI data centers in the United States due to labor shortages, power supply constraints, or local opposition could reduce demand across the AI hardware supply chain.
Conversely, Goldman Sachs projects that combined AI-related capital expenditure by the world's four largest hyperscale technology companies—Meta, Microsoft, Amazon, and Alphabet—could reach an astounding $5.3 trillion between fiscal years 2025 and 2030, signaling continued expansion in AI infrastructure. Samsung is scheduled to release its detailed second-quarter financial results on July 30.
