About Western Digital Corporation
About Western Digital Corporation
Western Digital, founded in 1970 and based in San Jose, California, makes hard disk drives and employed approximately 40,000 people at the end of 2026, about 88% of them in Asia Pacific. Its vertically integrated assembly and test operations are concentrated in Thailand, Malaysia, the Philippines, China and California, and it holds approximately 4,700 active patents. International sales represented 60% of net revenue in 2026, up from 55% in 2025.
The company sells high-capacity enterprise drives for Cloud data centers, drives for OEM desktop and notebook customers under Client, and external storage products through retail and channel partners under Consumer. Buyers include hyperscale cloud providers, neoclouds, computer manufacturers, resellers, distributors and retailers, and some customers purchase under long-term agreements that fix volumes and formula-based prices over multi-quarter or multi-year periods. Western Digital designs and manufactures substantially all of the recording heads and magnetic media in its drives, relies on an external supply base for the remaining components, and says its roadmap includes ePMR, OptiNAND, UltraSMR, HAMR and triple stage actuators. The 10-K names Seagate Technology Holdings and Toshiba Electronic Devices & Storage as HDD competitors, alongside NAND flash suppliers. The company separated its former Flash business in 2025.

Customer concentration is the sharpest feature of the filing. The Cloud end market accounted for 89% of net revenue and the top 10 customers for 73% in the year ended July 3, 2026, and three customers accounted for 16%, 15% and 13% of net revenue, compared with 17%, 12% and 10% in 2025. If hyperscale buyers reduce AI infrastructure investment, or a key customer is restricted by law or acquired by a competitor, results could weigh on the company. Long-term agreements may also prevent it from capturing higher prices if market rates rise above contracted levels, and some components come only from sole-source suppliers.
