What dominates the section

  • Cloud customers dominate revenue, with the Cloud end market at 88% and top 10 customers at 68% after the Sandisk separation.
  • The Sandisk spin-off leaves Western Digital smaller, less diversified, and more exposed to market and counterparty changes.
  • Supply-chain disruption, cybersecurity, technology transitions, and volatile data-center demand are central operating risks.

The risks most specific to Western Digital

  • BUSINESS AND STRATEGIC RISKS

    Loss of revenue from the Cloud end market or a key customer, or consolidation among our customer base, could harm our operating results

    The Sandisk separation increased dependence on Cloud customers: that market generated 88% of revenue, while the top 10 customers generated 68%.

  • BUSINESS AND STRATEGIC RISKS

    We are subject to risks related to the separation of Sandisk, our former Flash business, into an independent public company

    Separating Sandisk from the HDD business creates execution, contractual, tax, and counterparty risks as the new companies operate independently.

  • BUSINESS AND STRATEGIC RISKS

    and other counterparties. In addition, following the Separation, we are a smaller and less diversified company, which could make us more vulnerable to changing market conditions

    Western Digital is now smaller and less diversified after the separation, increasing vulnerability to changing conditions and problems with Sandisk-related agreements.

  • BUSINESS AND STRATEGIC RISKS

    We experience variability in our sales and cyclicality in our industry, which could cause our operating results to fluctuate. In addition, accurately forecasting demand is difficult, which could harm our business

    Demand is difficult to forecast because large Cloud customers’ data-center buildouts can make sales highly variable and cyclical.

  • OPERATIONAL RISKS

    We are dependent on a limited number of qualified suppliers who provide critical services, materials or components, and a disruption in our supply chain could negatively affect our business

    Dependence on limited suppliers for firmware, preamps, controllers, DRAM, equipment, and materials makes disruptions difficult to replace quickly.

  • OPERATIONAL RISKS

    The compromise, damage or interruption of our technology infrastructure, information systems or products by cybersecurity incidents, data security breaches, other security problems, design defects, information system failures or other events could have a material negative impact on our business

    Cyberattacks, data breaches, system failures, and product defects could compromise Western Digital’s infrastructure, cloud platforms, or products.

  • OPERATIONAL RISKS

    adversarial attacks, which could result in unauthorized access to or leakage of sensitive information. Geopolitical tensions or conflicts may also create heightened risk of cybersecurity incidents

    Malicious attacks target storage products and cloud services, while geopolitical tensions could increase incidents or force services offline.

  • BUSINESS AND STRATEGIC RISKS

    If we do not properly manage technology transitions and product development and introduction, our competitiveness and operating results may be negatively affected

    Rapid storage-technology transitions could leave product roadmaps behind market needs or cause failed development and introductions.

  • OPERATIONAL RISKS

    We are subject to risks related to product defects, which could result in product recalls or epidemic failures and could subject us to warranty, litigation or indemnification claims that exceed our expectations or estimates

    Undetected product defects could trigger recalls, epidemic failures, warranty costs, litigation, or indemnification claims beyond estimates.

About this page

Item 1A of the 10-K on EDGAR was split into its risk factors and, where the company's previous 10-K is on file, each heading was matched to last year's and the text compared word for word. The headings are the filing's own. The one-line readings and the overview were written by a language model from the text of the new, dropped, and rewritten risks; they refer to risks by position and cannot misquote a heading.
