SanDisk (SNDK) shares rose 2.4% in premarket trading on May 20, 2026. This movement follows news of a planned strike by 48,000 Samsung Electronics workers in South Korea.
The labor action follows failed negotiations over employee bonus payments. Any disruption to Samsung’s semiconductor production could tighten the global supply of memory chips.
Analysts indicate that supply interruptions may benefit rivals like SanDisk by shifting market dynamics and pricing. Demand for advanced memory remains high due to increasing investments in AI infrastructure.
