Western Digital Corporation
A maker of hard disk drives and storage products that keep data safe, from cloud data centers to home computers. Founded in 1970 as General Digital Corporation, it started out making calculator chips before pivoting to storage, renaming itself Western Digital in 1971 for a "broader industrial identity." It later absorbed flash-memory maker SanDisk, and today its drives power hyperscale data centers, PCs, and external storage sold in retail.

Select a row to see that insider’s individual transactions. Sum of the holdings confirmed in the 12 months before this insider's last filing. A Form 4 reports a holding per line — held directly, or through a named trust, partnership or foundation, and in each share class separately — never a person’s total. Lines not restated in that time are left out and shown apart: an active filer restates what they still hold, so a line they did not restate is more often an entity since renamed, whose shares a successor line reports too. An amber marker means some were left out.
Net open-market activity over the last 3 years: -600.9K shares. Grants, option exercises and tax withholding are excluded — they are compensation mechanics, not decisions to buy or sell.
