After reaching an all-time intraday high of $784.30, SanDisk Corporation (NASDAQ: SNDK) finished Tuesday at $780.90, up nearly 10% on the day, capping an incredible run that has seen the stock rise more than 2,000% in the last year.

The flash memory giant’s most recent jump coincides with a series of calculated actions that have drawn interest from Wall Street, most notably a historic $1 billion private placement investment in Taiwan-based Nanya Technology. As part of the agreement, SanDisk would purchase around 139 million shares of Nanya common stock, or about 3.9% of the business. A multi-year DRAM supply deal has been reached between the two companies in addition to the equity investment; this relationship significantly expands SanDisk’s memory technology portfolio beyond its conventional NAND strengths.
The Nanya acquisition comes after SanDisk recently separated from Western Digital, which has been reducing its ownership through secondary offers, and began operating as an independent public business. Recently, Western Digital priced a secondary sale of more than 5.8 million SanDisk shares for $545 per share; nevertheless, Western Digital receives all of the transaction’s revenues, not SanDisk.
A New Memory Powerhouse Taking Shape
The Nanya cooperation is viewed by analysts as a key strategic change. SanDisk now has a presence in both of the key memory technologies driving contemporary AI infrastructure, NAND for storage and DRAM for high-speed processing in AI servers and data centers, thanks to its expanded NAND joint venture with Japan’s Kioxia.
The timing is intentional. The rapid expansion of AI inference infrastructure has coincided with an increase in demand for memory chips, and SanDisk seems to be setting itself up to take a bigger market share. This week, BofA Securities reaffirmed its Buy rating on the stock, noting the company’s outlook being significantly influenced by the robust demand from AI inference applications.
In response to a wider sector selloff caused by investor worries about capital spending and waning demand signals elsewhere, Morgan Stanley has kept its Overweight rating on SanDisk and peer Micron Technology. The company stated that it remains confident in the long-term viability of the foundations of the memory industry.
SanDisk (SNDK) Stock Valuation Debate Heats Up
The valuation situation is complex despite the bullish momentum. With a current market value of about $104.91 billion, SanDisk’s stock is trading at about 111 times trailing profits, which is a high multiple for a business that hasn’t made money in the last 12 months. In contrast to Simply Wall St, which estimates that the shares trade about 61% below intrinsic value, InvestingPro labels the stock as overvalued in comparison to its determined Fair Value.
Although projections range widely from $600 to $1,000, suggesting genuine disagreement about where SanDisk’s rapid transition finally leads, the analyst consensus target is around $770, placing the company barely above Wall Street’s average price objective.
Tuesday’s after-hours trade saw shares slightly decline to $773.85.
SanDisk has solidified its position as one of the most closely watched names in the semiconductor industry with an 183.7% year-to-date gain, a bold new supply agreement in hand, and an acceleration of AI demand. However, investors will be closely monitoring whether the execution of the Nanya partnership can justify the stock’s historic ascent.
