Why Does It Matter?
- AI data-center demand: The storage capacity required to train and serve large language models is significantly increasing NAND demand
- Kioxia partnership: The manufacturing partnership with Japanese storage giant Kioxia provides scale advantages
- Independent re-listing: Separation from WD gives SanDisk the ability to pursue its own growth strategy independently

COINOTAG Perspective
SanDisk is a cyclical storage company with the potential to benefit from NAND storage demand driven by AI data-center growth. The Kioxia partnership and strong brand equity are the company''s core competitive advantages in the post-independence era. The NAND price cycle should be monitored closely as the primary driver of revenue and margins.
