South Korean memory-chip maker SK hynix reports a sharp jump in second-quarter profit driven by strong demand for AI-related chips. Multiple outlets say the company’s operating performance rises dramatically year-on-year, with one report citing a 557% increase in quarterly profit. Despite the record results, the company misses analysts’ forecasts, which fuels market concern about whether the pace of the AI-driven semiconductor boom can be sustained. Shares fall after the announcement, with reports describing steep drops ranging from around 10% to as much as 20%, reflecting investor disappointment at the gap between results and expectations. Some coverage links the market reaction to broader uncertainty, including geopolitical tensions in the Middle East, which investors worry could affect risk appetite or supply chains. Financial Times adds that SK hynix has secured multiyear contracts with roughly 10 customers, suggesting demand visibility even as expectations for further acceleration are not met. Overall, sources agree the quarter combines strong profitability with a forecast miss that tempers investor enthusiasm.
