Is Western Digital (WDC) a Buy in 2026 Amid AI-Driven Storage Demand?

The storage industry is undergoing a seismic shift driven by artificial intelligence (AI) and cloud computing, creating both opportunities and risks for players like Western Digital (WDC). As the company navigates this transformation, investors must assess whether its valuation, earnings momentum, and exposure to industry cyclicality justify a "buy" recommendation in 2026.

Earnings Momentum: Cloud-Driven Growth and Margin Expansion

Western Digital's fiscal 2025 results underscore its strategic pivot to cloud storage. In Q4 FY2025, the company reported revenue of $2.6 billion, a 30% year-over-year increase, with cloud revenue accounting for 90% of total sales. This trend accelerated in Q1 FY2026, where cloud revenue reached $2.5 billion, or 89% of total revenue, driven by demand for high-capacity nearline products. Non-GAAP gross margins expanded by 660 basis points year-over-year to 43.9% in Q1 FY2026, reflecting improved product mix and cost discipline.

Free cash flow (FCF) generation has also strengthened, with $675 million in FCF in Q4 FY2025 and $599 million in Q1 FY2026 according to investor reports. These metrics highlight WDC's ability to capitalize on AI-driven demand, particularly as hyperscale cloud providers lock in long-term contracts. The company's board further signaled confidence by raising its quarterly dividend by 25% to $0.125 per share.

Valuation Analysis: Premium Pricing Amid Historical Discrepancies

Despite robust earnings, WDC's valuation appears stretched. As of December 2025, its enterprise value to EBITDA (EV/EBITDA) ratio stands at 16.91, significantly above its 3-year average of 8.74 and 10-year average of 8.43. This premium reflects strong market expectations for AI-driven growth but raises concerns about overvaluation. Alpha Spread estimates WDC's intrinsic value at $129.59, suggesting a 25% overvaluation relative to its current price of $172.27.

The company's trailing price-to-earnings (P/E) ratio of 24.25 and forward P/E of 20.99 according to financial data also indicate a premium, though these are lower than the EV/EBITDA multiple. While WDC's enterprise value to sales ratio of 5.99 appears reasonable according to stock analysis, its EV/FCF ratio of 31.29 highlights reliance on future cash flow growth rather than current profitability. Analysts remain divided: some argue the valuation is justified by structural AI tailwinds, while others caution against overpaying for cyclical demand.

Industry Cyclicality: Risks and Mitigants in a Shifting Landscape

The storage sector remains inherently cyclical, with demand tied to macroeconomic conditions and technological adoption. For instance, WDC's consumer segment revenue declined 1% year-over-year in Q1 FY2026, underscoring vulnerability to softening demand in non-cloud markets. Additionally, trade tensions and tariffs could disrupt supply chains or reduce margins.

However, WDC's dominance in the nearline exabyte market-where it holds a 48% share-provides a buffer. Long-term contracts with hyperscale customers, covering through 2027, further insulate the company from short-term volatility. Competitor Seagate (STX) faces similar risks but has adopted HAMR technology more aggressively, though WDC's roadmap for 40TB+ HAMR drives in late 2026 positions it to reclaim market share.

Analyst Sentiment: Bullish Consensus with Caution

Analysts remain largely optimistic. As of Q4 2025, 21 analysts rated WDC as a "Buy," with 38% recommending a "Strong Buy" and a consensus price target of $162.95. Some, like Morgan Stanley, highlight structural tailwinds from AI and cloud growth, while others project higher targets, such as $250. The stock's 300% surge in 2025 according to market analysis has priced in much of this optimism, though the 25% overvaluation flagged by intrinsic value models according to Alpha Spread suggests caution.

Conclusion: A Calculated Buy for the Long-Term

Western Digital's earnings momentum and strategic alignment with AI-driven storage demand make it an attractive long-term play. Its cloud-centric business model and margin expansion demonstrate resilience, while its valuation, though elevated, is supported by structural growth narratives. However, investors must weigh the risks of overvaluation and industry cyclicality. For those with a multi-year horizon and tolerance for volatility, WDC's position as a leader in high-capacity storage-coupled with its dividend and buyback program-justifies a "buy" rating in 2026.
