what happened
According to Stocktwits, U.S.-listed shares of SK Hynix (SKHY) dropped 4% in premarket trading on Tuesday. The move followed an announcement by a union at rival Micron (MU) of a strike in Taiwan over employee bonuses and profit sharing. Citing Reuters, Stocktwits reports that the Taoyuan union plans a walkout on Thursday, while a separate union at the larger Taichung site is in mediated talks with management.
Unions are seeking quarterly bonuses tied to 15% of operating profit. The source says Taoyuan members authorized strike action earlier this month after mediation failed last month. Taiwan hosts major Micron DRAM and high-bandwidth memory operations, and President Lai Ching-te urged sincere negotiations between the company and its workers.
why it matters
The story matters for the AI memory market, where SK Hynix and Micron compete in DRAM and HBM, so any production disruption could affect supply expectations. Memory stocks had already sold off after Chinese chipmaker CXMT announced a next-generation DDR5 server module. Per Koyfin, SK Hynix revenue is projected to rise 46% from the previous quarter. Year to date, SKHY is down 15% while MU is up 217%.
