SanDisk has exceeded analysts’ consensus on eight of the past ten quarterly reports, delivering an average earnings surprise of 6%. The company combines robust revenue growth—23% year-over-year in Q1 of fiscal 2026, driven by data-center SSD demand—with operating leverage from high factory utilization. Management forecasts revenue of $10.45 billion for full-year fiscal 2026, up 42% and implying double-digit profit expansion as flash memory prices remain elevated. These factors position SanDisk to potentially outpace Wall Street estimates once again when it reports results on January 26.

Shares of SanDisk have rallied for five consecutive trading days, yielding a cumulative gain of 30% and adding roughly $17 billion in market cap to reach $74 billion. This surge reflects institutional shifts into high-performance storage amid booming AI infrastructure spending. Volume on recent up-days has exceeded the three-month average by 60%, underscoring strong buyer conviction. Investor interest is also supported by a Zacks Rank #1 rating, driven by upward EPS revisions of over 100% in the past three months.

Despite momentum, several Wall Street strategists caution that SanDisk’s valuation—now trading at more than 205 times forward earnings—could be vulnerable when NAND supply constraints ease. J.P. Morgan projects a potential 53% decline based on mean reversion in memory pricing once production capacity shifts back from AI-optimized wafer lines. With consensus earnings growth of 79% per year through fiscal 2029 baked into current multiples, any signs of a supply glut could trigger significant share-price pressure, prompting recommendations for position trimming by holders with large exposure.
