WESTERN DIGITAL CORPORATION
Western Digital Corporation is a Delaware-incorporated, publicly traded technology company that designs, manufactures and sells data storage devices, with its principal executive offices at 5601 Great Oaks Parkway, San Jose, California. The registry record on file for this profile is a Florida Department of State (Sunbiz) foreign-qualification filing, document number P09519, first filed on March 25, 1986, and shown as inactive following a withdrawal registered on February 2, 1987. That record reflects only a discontinued out-of-state qualification from the 1980s, when Western Digital’s operations were based in Irvine, California, and does not indicate that Western Digital Corporation itself has ceased trading. The company remains an active, Nasdaq Global Select Market-listed issuer under the ticker WDC, with Securities and Exchange Commission Central Index Key 0000106040.
Western Digital Corporation develops, manufactures and sells hard disk drives (HDDs) for cloud data centers, enterprise storage systems, client computing devices and consumer external-storage products, serving Cloud, Client and Consumer end markets. On February 21, 2025, the company completed the previously announced separation of its flash-memory (NAND) business, distributing approximately 80.1% of the outstanding shares of Sandisk Corporation to Western Digital stockholders. Sandisk began trading independently on Nasdaq under the ticker SNDK, and its results are no longer consolidated with Western Digital Corporation’s financial statements. Following the separation, Western Digital Corporation operates solely as an HDD storage business.
For fiscal year 2025, ended June 27, 2025, Western Digital Corporation reported total net revenue of approximately 9.52 billion US dollars from continuing operations, the post-separation HDD business, an increase of 51 percent over the prior fiscal year, with GAAP gross margin of 38.8 percent. The company reported approximately 40,000 employees worldwide as of the end of fiscal year 2025, with roughly 88 percent based in the Asia-Pacific region.
Since the separation, Western Digital Corporation has undergone significant leadership change. Irving Tan became Chief Executive Officer and a director in February 2025, and Kris Sennesael was appointed Executive Vice President and Chief Financial Officer effective May 12, 2025, following an interim period. The company initiated a quarterly cash dividend of 0.10 US dollars per share and authorized a 2.0 billion US dollar share-repurchase program during fiscal year 2025.

Shareholders of Western Digital Corporation
Western Digital Corporation is a widely held, Nasdaq-listed public company (ticker WDC) with no single controlling shareholder. The disclosed shareholder data on file lists eight institutional or fund-level holdings, of which five are detailed, each representing an individual index or sector fund rather than a consolidated parent asset-manager position: VANGUARD INDEX FUNDS – Vanguard Mid-Cap Index Fund (approximately 3.0%), iShares Trust – iShares Core S&P 500 ETF (approximately 1.7%), Fidelity Select Portfolios – Select Semiconductors Portfolio (approximately 1.8%), Fidelity Concord Street Trust – Fidelity 500 Index Fund (approximately 1.7%), and SPDR S&P 500 ETF Trust (approximately 1.6%), each verified as of August 2, 2026. These are individual sub-funds administered by larger asset-management groups rather than single reportable owners. Separately, Schedule 13G filings referenced in Western Digital’s proxy statements have shown The Vanguard Group’s aggregate family of funds holding approximately 11.9% and BlackRock, Inc.’s aggregate family of funds holding approximately 8.5% of outstanding shares as of the fiscal year 2024 proxy statement, figures that combine numerous individual funds, including those listed above, under one reporting entity. Because Western Digital Corporation’s shares are held predominantly by public investors and institutional asset managers, this disclosure should be read as major shareholders only, covering large institutional or index-fund positions rather than a complete register of all shareholders.
Data availability
The shareholder information available for Western Digital Corporation reflects institutional and index-fund filings for a Nasdaq-listed public company; it does not include the complete shareholder base. No individual ultimate beneficial owner has been identified, consistent with a widely held public company where ownership is dispersed among many institutional and individual investors.

Directors and officers of Western Digital Corporation
The officer records currently on file for this profile are outdated and do not reflect Western Digital Corporation’s present leadership. They combine two unrelated, superseded sources: four individuals, Edward L. Marinaro, Chester A. Brown, William R. Benz and Joseph Baia, listed as active vice presidents or officers, whose details correspond to a Florida Department of State foreign-qualification filing (document number P09519) made on March 25, 1986 and withdrawn on February 2, 1987, nearly four decades ago; and Wissam G. Jabre, listed as active Executive Vice President and Chief Financial Officer, a role he left when he resigned effective February 28, 2025. None of these five individuals currently hold an active executive role at Western Digital Corporation based on the company’s own SEC filings and press releases.
According to Western Digital Corporation’s SEC filings and official announcements, Irving Tan has served as Chief Executive Officer and a director since February 2025, having previously served as Executive Vice President, Global Operations, and Kris Sennesael has served as Executive Vice President and Chief Financial Officer since May 12, 2025, succeeding an interim Chief Financial Officer, Don R. Bennett, who held the position from February 28, 2025. Martin I. Cole serves as independent Chairman of the Board, a director since 2014. The Board comprises nine directors, most of them independent, with standing Audit, Compensation and Talent, and Governance committees.

Data availability
Officer and director information for a US public company such as Western Digital Corporation is disclosed through SEC filings, including Forms 10-K, DEF 14A, 3, 4 and 8-K, rather than a state corporate registry. Nationality is not required to be disclosed in these filings and is not stated for any individual named above; where it is not officially disclosed it is reported here as not disclosed. The on-file registry officer data is historical and outdated, last reflecting a 1986-1987 Florida filing and a since-ended 2022-2025 CFO appointment, and should not be relied upon for the company’s current leadership.

Group Structure
Group structure of Western Digital Corporation
Western Digital Corporation is the ultimate publicly traded parent of a group of subsidiaries that carry out its hard-disk-drive design, manufacturing, sales and financing activities worldwide, as listed in Exhibit 21.1 to its fiscal year 2025 Form 10-K, filed August 14, 2025. The verified group includes 42 subsidiaries incorporated across the United States, including Delaware, California and Hawaii, the Cayman Islands, Hong Kong, mainland China, Japan, South Korea, Singapore, Malaysia, Thailand, India, the Philippines, Australia, the United Arab Emirates, and several European jurisdictions including the United Kingdom, France, Germany, Italy, Spain, Sweden, Denmark and the Netherlands. Western Digital Technologies, Inc., a Delaware corporation, is the principal US operating subsidiary. Western Digital Corporation has no identified parent company; it is an independent, publicly traded entity.
Important note on data quality: the corporate-linkage data previously on file for this profile includes several entities, among them Sandisk China LLC, Sandisk Latin America Holdings LLC, Sandisk Manufacturing Americas LLC, Sandisk Enterprise IP LLC, Sandisk Holdings LLC, Sandisk GK, Sandisk Korea Inc., Sandisk Information Technology (Shanghai) Co., Ltd., Stec Inc. and related entities, Amplidata, Fusion-io LLC, Western Digital (Argentina) S.A., Western Digital Latin America, Inc. and Sepung Electronic Industry Co., Ltd., that do not appear in the verified fiscal year 2025 Exhibit 21.1 subsidiary list. The Sandisk-named entities in particular relate to the flash-memory business that Western Digital Corporation spun off into the independent Sandisk Corporation on February 21, 2025, and are no longer part of the Western Digital Corporation group. This on-file data therefore appears to reflect a pre-separation or otherwise outdated corporate structure and should not be treated as current.
