YTD as of 2026-07-09 · source: Yahoo Finance
The core of Phison is a mix shift as its position as the world's largest independent NAND controller extends into server and AI storage. Partnering with NAND makers (Kioxia, Micron, WD, Samsung, SK) and buying ~16EB of raw NAND at wafer level to add value through controllers and SSDs, its results are two-way exposed to the NAND price cycle and allocation. The growth axis is the 70%+ non-consumer (server/AI) share plus on-prem LLM training storage (aiDAPTIV+), which reduce the cyclicality of consumer USB/eMMC. In graph terms Phison is a cost node to TSMC (controller foundry) and NAND makers and a revenue node to Kingston, Seagate and server customers, so how fast the NAND bottleneck clears and AI-storage adoption ramps are the margin swing factors.
