- Sandisk issued underwhelming fiscal 2027 revenue guidance that sent its own shares sharply lower and dragged down related memory chip market indexes.
- SK Hynix (SKHY) plummeted about 10% in premarket trading, joining other South Korean and Japanese memory makers in a broad sector selloff triggered by Sandisk's results.
- Nvidia and several major AI chipmakers were largely flat or dipped only slightly in premarket, indicating less direct exposure to the memory-specific guidance miss.
- Other AI and networking-related stocks saw mixed premarket action, with both gains and losses across the sector as the Sandisk news weighed unevenly.
- Chip equipment makers MKS and ASML rose after posting strong results, bucking the broader chip-sector downtrend, while Applied Materials traded in the red.
Why it matters: Sandisk's weak forward guidance doesn't just hit one stock — it pulled SK Hynix down 10% and dragged down memory peers across South Korea and Japan, showing how a single fiscal 2027 revenue outlook can ripple across the global memory chip supply chain and sector indexes.
