Sandisk SNDK hosted a bullish investor day on Aug. 13, focusing on long-term secular demand trends for NAND memory, AI, and long-term customer contracts. Management provided attractive long-term targets, including double-digit revenue growth through 2030 and 80% non-GAAP gross margin.

Why it matters: Sandisk continues to preach that this time is different for NAND, and the current upcycle will be structural and durable. We disagree and expect commodity supply/demand market dynamics to create volatile cycles into the long term.

• Demand isn’t a question to us—we expect memory needs to rise durably in both personal devices and data centers. For memory, it comes down to the ratio of supply to demand, which governs prices. If supply exceeds demand, it creates pricing compression that can hurt sales and margins.
• In our view, long-term customer agreements hedge downside cycle risk, rather than prevent it altogether. We observe that less than 20% of Sandisk’s contract values are financially guaranteed, and we believe customers hold the power to amend terms if spot market prices fall.

The bottom line: We maintain our $1,000 per share fair value estimate for no-moat Sandisk. Our long-term thesis for cyclicality in the NAND market is unchanged, and we continue to worry about a downcycle beginning in the 2029 timeframe. Shares look overvalued to us.

• Shares are up nearly 7 times year to date as rising NAND prices have led Sandisk’s revenue and profitability to balloon. The current upcycle has led our valuation higher, too, but we can’t justify the current market price given the risk of a pricing downturn toward the end of the decade.
• We expect superb growth through fiscal 2028 for Sandisk but expect prices to peak in early 2028 and then fall precipitously in 2029 and 2030. We believe end-of-decade profitability will be lower than current levels, but we expect a better midcycle outlook than Sandisk has offered historically.
