SK Hynix’s Record Profit Misses Investors’ Lofty AI Expectations

SK Hynix reported a six-fold surge in quarterly profit and unveiled at least $31 billion in capital expenditure planned for this year, a record outlay for the South Korean chipmaker. Despite the earnings jump, the results missed investor expectations tied to artificial intelligence demand.

The company's shares fell as the massive capex commitment raised concerns about overinvestment in the memory chip sector. SK Hynix has been a key supplier of high-bandwidth memory (HBM) chips used in AI accelerators, positioning it as a primary beneficiary of the AI infrastructure buildout. The record spending signals the company is betting heavily on sustained demand from data center customers.

The earnings beat on absolute terms but the market reaction suggests investors had priced in even stronger AI-driven performance. The $31 billion capital spending figure represents a significant escalation from prior years, reflecting both capacity expansion and advanced packaging technology investments needed for next-generation HBM products.
