SanDisk Corporation revealed details of a major secondary public offering that will see its former parent company offload millions of shares.

SanDisk’s Stellar Run Faces Immediate Pressure

Investors reacted swiftly to the announcement, driving SanDisk’s shares down more than 3.5% in premarket trading on Wednesday.

That pullback came despite impressive gains throughout 2026, with the stock climbing roughly 148% so far this year and surging nearly 1,184% over the past 12 months. The company had separated from Western Digital nearly a year earlier and earned a spot in the S&P 500 by November. Such momentum positioned SanDisk as a standout in the volatile tech sector. Yet the latest news introduced fresh uncertainty for shareholders.

Details of the Secondary Offering Emerge

Western Digital plans to sell 5,821,135 common shares of SanDisk, listed on Nasdaq as SNDK, priced at $545 each.

The transaction values the offering at approximately $3.2 billion and involves a debt-for-equity swap with J.P. Morgan Securities LLC and BofA Securities serving as the selling stockholders. After this sale, Western Digital will hold just 1,691,884 shares but intends to divest those as well. SanDisk emphasized that it would neither sell shares nor receive proceeds from the deal, as outlined in its recent filing. Regulators expect the offering to finalize on Thursday, February 19.

Roots in a Strategic Corporate Split

The move caps the ongoing separation process that began when SanDisk split from Western Digital around a year ago.

That independence allowed SanDisk to chart its own course, culminating in S&P 500 inclusion and robust market performance. Western Digital, meanwhile, has continued streamlining its holdings. The secondary offering represents a key step in fully disentangling the two entities. Observers view it as a logical progression rather than a sign of distress.

AI Demand Powers Memory Chip Surge

SanDisk’s fortunes align closely with a broader rally in memory chips, fueled by insatiable AI-driven demand.

A global shortage of chips has sent prices soaring, benefiting producers across the board. Western Digital’s shares rose about 1.68% in premarket trading and gained 422% year-over-year. Micron Technology posted even stronger results, up 283% over the same period. Companies like these have capitalized on the scramble for high-capacity memory essential to AI applications, as detailed in recent industry analysis.

Company 2026 YTD Gain 12-Month Gain
SanDisk (SNDK) ~148% ~1,184%
Western Digital (WDC) N/A 422%
Micron N/A 283%

Key Takeaways:

  • SanDisk’s secondary offering totals $3.2 billion in shares from Western Digital.
  • Stock dipped 3.5% premarket but remains up massively in 2026.
  • AI shortages continue propelling memory chip leaders forward.

While the share sale tests SanDisk’s momentum, the underlying AI tailwinds suggest resilience ahead. Investors will watch closely as the sector navigates supply constraints and corporate realignments. What implications do you see for memory stocks in the coming months?
