Organization, Consolidation and Presentation of Financial Statements [Abstract] |
Organization and Basis of Presentation | Organization and Basis of Presentation Western Digital Corporation (“Western Digital” or the “Company”) is a leading developer, manufacturer, and provider of data storage devices and solutions based on hard disk drive (“HDD”) technology. The Company manufactures, markets, and sells data storage devices and solutions in the United States (“U.S.”) and in foreign countries through its sales personnel, dealers, distributors, retailers, and subsidiaries. Its broad portfolio of technology and products addresses the following key end markets: Cloud, Client, and Consumer. The Company also generates immaterial license and royalty revenue from its extensive intellectual property portfolio, which is included in each of these three end market categories. The accounting policies followed by the Company are set forth in Part II, Item 8, Note 1, Organization and Basis of Presentation, of the Notes to the Consolidated Financial Statements included in the Company’s Annual Report on Form 10‑K for the year ended June 28, 2024 (the “2024 Annual Report on Form 10-K”). In the opinion of management, all adjustments necessary to fairly state the Condensed Consolidated Financial Statements have been made. Such adjustments consist of items of a normal, recurring nature. Certain information and footnote disclosures normally included in the Consolidated Financial Statements prepared in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”) have been condensed or omitted pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). These Condensed Consolidated Financial Statements should be read in conjunction with the Consolidated Financial Statements and the notes thereto included in the 2024 Annual Report on Form 10‑K. The results of operations for interim periods are not necessarily indicative of results to be expected for the full year. Information provided herein is presented on a continuing operations basis to reflect the impact of the Separation of the Company’s Flash business as discussed in further detail in Note 3, Discontinued Operations. Fiscal Year The Company’s fiscal year ends on the Friday nearest to June 30 and typically consists of 52 weeks. Approximately every five to six years, the Company reports a 53-week fiscal year to align the fiscal year with the foregoing policy. Fiscal year 2025, which will end on June 27, 2025, and fiscal year 2024, which ended on June 28, 2024, are each comprised of 52 weeks, with all quarters presented consisting of 13 weeks. Segment Reporting Historically, the Company had been managed and operated under two reportable segments: hard disk drives (“HDD”) and Flash-based products (“Flash”). As a result of the Separation (as defined in Note 3, Discontinued Operations) and disposition of the Flash segment, the Company’s continuing operations now consist of a single reportable segment, HDD. The Chief Executive Officer, who is the Company’s Chief Operating Decision Maker (“CODM”), now evaluates the performance of the Company and makes decisions regarding the allocation of resources based on the Compan y’s consolidated results. Use of Estimates Company management has made estimates and assumptions relating to the reporting of certain assets and liabilities in conformity with U.S. GAAP. These estimates and assumptions have been applied using methodologies that are consistent throughout the periods presented. However, actual results could differ materially from these estimates.
