Why is Micron Stock Sinking Today

Micron Technology (MU) shares dropped 5% after a labor dispute halted construction of a $3B-$4.5B memory chip facility in Taiwan, potentially delaying its 2028 operations. The delay impacts Micron's competition with Samsung, SK Hynix (SKHY), and CXMT in the memory market, particularly for AI-related HBM chips. The dispute centers on employee compensation, with negotiations ongoing. Taiwan's government is assisting with the investment plans.
