About Western Digital Corporation
About Western Digital Corporation
Three customers each accounted for 10% or more of Western Digital's net revenue in fiscal 2025 — 17%, 12%, and 10%, respectively — a shift from fiscal 2024 and 2023, when no single customer crossed that threshold. International sales made up 55% of fiscal 2025 net revenue, down from 58% in fiscal 2024, and Western Digital sells HDDs across Cloud, Client, and Consumer end markets under the Western Digital and WD brands, backed by a workforce of approximately 40,000 people, 88% of them in Asia Pacific.
Western Digital sells HDDs to cloud service providers, computer manufacturers and OEMs, resellers, distributors, and retailers worldwide, with sales offices across the Americas, Asia Pacific, Europe, and the Middle East. The company designs and manufactures substantially all of its own recording heads and magnetic media in-house — reducing reliance on outside recording-head and media technology — while depending on an external supply base for remaining components, including a limited number of sole- or single-source providers for certain parts. Vertically integrated assembly and test operations run at facilities in Prachinburi and Bang Pa-In, Thailand; Penang, Johor Bahru, and Kuching, Malaysia; Laguna, Philippines; Shenzhen, China; and San Jose and Fremont, California. Western Digital competes against Seagate Technology and Toshiba Electronic Devices & Storage in HDDs, as well as NAND flash suppliers offering alternative storage technologies, and held approximately 4,500 active patents as of fiscal 2025, covering magnetic recording and related technologies.

Western Digital's 10-K ties its buying-pattern volatility directly to a specific customer type: the company states that sales variability is largely dependent on the buying patterns of its large Cloud customers, driven by their data-center buildout needs and their ability to separately procure the other components those buildouts require. That mechanism means Western Digital's revenue predictability is tied less to its own execution and more to hyperscaler capital-spending cycles — a distinct, named cyclicality driver separate from the general macroeconomic and industry cyclicality the filing also discloses.
