Composite trend over time
Why is SNDK moving today?
Sandisk is one of the five largest suppliers of NAND flash memory semiconductors globally. Sandisk is vertically integrated, producing substantially all of its flash chips at manufacturing sites across Japan via a joint-venture framework with Kioxia. Sandisk then repackages most of its chips into SSDs for consumer electronics, external storage, or cloud storage. Sandisk was formerly a piece of Western Digital for nine years (after being acquired in 2016) and was spun off as an independent company in 2025.
