SK Hynix Shares Plunge 10% Despite Record Profits Missing High Investor Expectations
SK Hynix reported a record quarterly operating profit of 60.5 trillion won and revenue of 79.3 trillion won, but both missed market expectations of 64 trillion and 84 trillion won respectively. Consequently, the company's stock price plunged 9.6% in a single day amid growing concerns over the sustainability of AI infrastructure investments. As a key Nvidia supplier, SK Hynix's missed expectations highlight investor anxiety about whether massive AI infrastructure spending by tech giants will yield sustainable returns. To mitigate market volatility, SK Hynix is shifting toward long-term five-year supply agreements, which may stabilize revenue but limit short-term price gains. The earnings miss was partly attributed to slower-than-expected shipments of HBM4 products, delaying revenue recognition. Additionally, investors were disappointed by the lack of a clear shareholder return policy and the potential price-capping effect of the newly negotiated long-term supply contracts.
## BACKGROUND
High Bandwidth Memory (HBM) is a specialized 3D-stacked DRAM interface designed for high-performance computing and AI accelerators, pioneered by companies like SK Hynix. Standard DRAM (Dynamic Random-Access Memory) is volatile computer memory used for temporary data storage, which has seen surging demand and prices due to the AI boom crowding out commodity DRAM production capacity.
