Western Digital Corporation, WDC

The catalyst for this movement originated from SanDisk, the Flash memory division that Western Digital previously owned. During its Investor Day presentation on August 13, SanDisk unveiled projections showing mid-teens percentage annual revenue expansion spanning fiscal years 2028 to 2030, fueled primarily by artificial intelligence infrastructure requirements. This announcement sent SanDisk shares rocketing more than 13% in overnight trading, creating a positive spillover effect across storage sector equities.

Additionally, SanDisk disclosed that it had secured multi-year agreements with eight separate customers through a restructured business framework, providing market participants with tangible evidence of its strategy to capitalize on sustained AI-related storage investment.

This industry momentum arrived at an opportune moment for WDC. The company had previously released impressive Q4 FY2026 financial results on August 4, delivering adjusted earnings per share of $3.56 compared to analyst expectations of $3.29. Revenue reached $3.75 billion, representing a 43.8% year-over-year increase and surpassing the $3.70 billion forecast.

Forward Outlook Exceeds Projections

Looking ahead to Q1 FY2027, Western Digital’s management issued guidance calling for approximately $4.1 billion in revenue alongside gross margins ranging from 55% to 56%, figures that surpassed Street expectations on both metrics.

The company generated approximately $3.5 billion in free cash flow during fiscal 2026, further strengthening the optimistic narrative surrounding the equity among market analysts.

Wall Street analysts responded to the results with revised price targets. JPMorgan elevated its target from $530 to $650 while maintaining an “overweight” recommendation. Rosenblatt preserved its “buy” rating but adjusted its target downward from $900 to $800. Zacks had previously upgraded the stock to “strong-buy” status earlier in the year. The overall analyst consensus registers as “Moderate Buy” with a mean price target of $534.56.

Fair value calculations for the stock were also adjusted higher, moving from $584.79 to $662.13 based on updated financial models.
