Company Description

Western Digital manufactures and sells data storage devices and solutions based on HDD technology in the United States, Asia, Europe, the Middle East, and Africa. The company offers internal HDDs, data center drives and platforms, as well as external and portable drives.

In a year where artificial intelligence reshaped the technology landscape, few companies captured the momentum quite like Western Digital. Innovations such as UltraSMR and heat-assisted magnetic recording have enabled the company to ship industry-leading 30TB+ drives tailored for AI data lakes. Strong free cash flow generation and a fortified balance sheet provide additional financial flexibility as the company capitalizes on multi-year hyperscaler buildouts.

The storage specialist, a standout in the Zacks Computer – Storage Devices industry, witnessed its shares surge nearly 300% last year, significantly outperforming both the broader market and its peers. And the industry's tailwinds are just getting started. AI-powered storage markets are exploding—from $30.27 billion in 2025 to a projected $187.61 billion by 2035 at a 20% compounded annual growth rate. Data center operators and hyperscalers continue to expand infrastructure at an unprecedented pace, driving sustained demand for the company’s HDD solutions.

Earnings Trends and Future Estimates

What stands out is Western Digital’s consistent ability to deliver positive earnings surprises; the storage provider has exceeded EPS estimates in each of the past 11 quarters. The company delivered a trailing four-quarter average surprise of over 9%, reflecting strong execution in converting AI-driven demand into results. This track record aligns perfectly with the power of the Zacks Rank system, which prioritizes stocks showing upward earnings revisions.

Western Digital’s transformation has been remarkable. The company reported fiscal first-quarter results back in October that exceeded expectations, with adjusted EPS of $1.78 beating the Zacks Consensus Estimate by nearly 12%. Revenue of $2.8 billion topped forecasts by about 4%. Increasing sales in the cloud end market are being driven by solid demand for higher-capacity nearline products.

The California-based company has been the beneficiary of improving earnings estimate revisions as of late. Looking into fiscal 2026, analysts have raised their annual EPS estimates by 0.39% in the past 60 days. The Zacks Consensus Estimate now stands at $7.66 per share, reflecting better than 55% growth relative to the prior year.

Notice how shares remain above upward-sloping 50-day (blue line) and 200-day (red line) moving averages. The momentum appears to be carrying over into 2026. With both strong fundamentals and technicals, Western Digital stock is poised to continue its outperformance.

Empirical research shows a strong correlation between near-term stock movements and trends in earnings estimate revisions. As we know, Western Digital has recently witnessed positive revisions. As long as this trend remains intact (and WDC continues to deliver earnings beats), the stock will likely continue its bullish run throughout this year.

Bottom Line

Backed by a leading industry group and robust history of earnings beats, it’s not difficult to see why this company is a compelling investment. Currently, WDC carries a Zacks Rank #1 (Strong Buy), driven by favorable estimate momentum.

Solid institutional buying should continue to provide a tailwind for the stock price. Robust fundamentals combined with a strong technical trend certainly justify adding shares to the mix. If you haven’t already done so, be sure to put WDC on your watchlist.
