Micron rises 15% after strong earnings, boosting chip shares

Micron shares jumped about 15% on Thursday after the memory chip maker reported strongerthanexpected thirdquarter results. The company said revenue more than quadrupled from a year earlier, reflecting higher demand tied to the artificial intelligence buildout. The report also lifted other semiconductor stocks, including Sandisk, Western Digital, Seagate, Intel, AMD, Qualcomm, and Applied Materials. Investors have been watching the sector closely after a recent selloff, and Micron’s results helped restore confidence in the AIdriven demand outlook. Micron said it has signed multiple longterm agreements with customers across data centers and automakers, which may support future sales. Analysts said those contracts could help reduce margin pressure if demand slows, although the broader chip cycle still depends on how AI infrastructure spending develops.
