Western Digital Corporation: 2007 Fiscal Year Summary

Business Context and Reporting Period

This summary covers the Annual Report on Form 10-K for Western Digital Corporation (WDC) for the fiscal year ended June 29, 2007. Western Digital designs, develops, manufactures, and sells hard drives for desktop, mobile, enterprise, and consumer electronics markets. The company operates manufacturing facilities in Malaysia and Thailand, with head wafer fabrication in California. A significant strategic development during the period was the announcement of a definitive agreement to acquire Komag, Incorporated, a media manufacturer, for approximately $1.0 billion.

Key Financial Metrics

Note: Unit shipments increased to 97 million in 2007 from 73 million in 2006. Average Selling Price (ASP) declined to $57 from $59.

Material Changes vs. Prior Period

• Revenue Growth: Net revenue increased 26% year-over-year, driven by a 33% increase in unit shipments. This growth was fueled by expanding market share in the desktop sector and significant growth in non-desktop sources (mobile, CE, enterprise, and retail), which rose from 29% of revenue in 2006 to 43% in 2007.
• Margin Compression: Gross margin percentage decreased from 19.1% to 16.5%. Management attributed this to normal technology price declines, a more competitive pricing environment, and a less favorable supply/demand balance compared to 2006.
• Profitability: Despite margin compression, Net Income increased 43% to $564 million. This was significantly aided by a $121 million income tax benefit in 2007 (compared to a $13 million benefit in 2006), largely due to the reversal of the valuation allowance on deferred tax assets.
• Operating Expenses: Total operating expenses as a percentage of revenue decreased to 8.9% from 10.7%, reflecting operational leverage despite increased R&D spending ($306 million) and SG&A ($179 million).

Guidance, Outlook, and Risks

Strategic Outlook: The company is executing a strategy of vertical integration. The planned acquisition of Komag is intended to integrate media manufacturing, enhancing production efficiencies. The company expects capital additions for fiscal 2008 to be between $600 million and $650 million, with approximately $200 million dedicated to expanding head wafer fabrication capacity.

Management Commentary: Management highlighted the successful diversification of revenue streams away from the traditional desktop market. They noted that the realization of deferred tax assets was based on a history of cumulative pretax income and the increased likelihood of future profitability.

Risks and Contingencies:

• Industry Pricing: The hard drive industry faces persistent declines in Average Selling Prices (ASPs) due to competition and technological advancements.
• Supply Chain: The company relies on a limited number of suppliers for critical components. Disruptions or shortages could impact production.
• Acquisition Integration: Risks exist regarding the successful integration of Komag's operations and technology within the expected timeframe.
• Legal Proceedings: The company is involved in derivative actions regarding historical stock option grants and patent infringement litigation (e.g., StorMedia Texas LLC), though management believes the financial impact will not be material.
• Foreign Operations: Manufacturing is concentrated in Asia (Malaysia and Thailand), exposing the company to geopolitical risks, natural disasters, and currency fluctuations (Thai Baht and Malaysian Ringgit).

Key Facts for Investor Verification

• Komag Acquisition Status: Verify the closing of the $1.0 billion Komag acquisition and the terms of the $1.3 billion bridge loan facility intended to fund it.
• Tax Benefit Sustainability: Assess the sustainability of the effective tax rate, which was significantly impacted by a one-time $126 million adjustment to the valuation allowance for deferred tax assets.
• ASP Trends: Monitor the trajectory of Average Selling Prices, which declined to $57, and the company's ability to maintain margins in a competitive environment.
• Customer Concentration: Note that sales to Dell accounted for 10% of total revenue in 2007, and the top 10 customers accounted for 47% of revenue.
• Capital Expenditures: Track the execution of the planned $600-$650 million capital expenditure budget for 2008, specifically the expansion of head wafer fabrication.
