Quick Summary
- SanDisk (SNDK) stock reached a 52-week peak of $2,354.39 on June 22 before declining, maintaining a year-to-date gain exceeding 700% in 2026.
- The downturn was partially attributed to a significant collapse in South Korea’s Kospi index and questions surrounding the longevity of AI-fueled memory chip demand.
- According to Morgan Stanley, SanDisk views AI as a transformative force in the NAND industry, propelled by expanding inference requirements and enlarged LLM context windows.
- Third-quarter FY2026 revenue jumped 251% compared to the previous year, reaching $5.95 billion and exceeding Wall Street’s $4.55 billion projection.
- Fourth-quarter projections anticipate revenue between $7.75B and $8.25B, with non-GAAP EPS estimated at $30 to $33.
SanDisk (SNDK) stock has emerged as one of 2026’s most remarkable performers. Following a year-to-date surge exceeding 700%, the stock reached a 52-week peak of $2,354.39 on June 22. However, a subsequent selloff followed.
The shares declined substantially in tandem with other memory semiconductor stocks, pressured by a dramatic downturn in South Korea’s Kospi benchmark and renewed concerns about the sustainability of AI-driven memory chip expenditure growth. SNDK has fallen approximately 13.6% in recent trading, declining about 5.75% across the past five sessions. The stock was changing hands near $1,963.60 during recent market activity.
Despite the recent decline, shares maintain a 32.8% gain over the trailing 30-day period. This perspective is crucial — the current volatility represents the first significant examination of the AI memory investment thesis following SanDisk’s separation from Western Digital in early 2025.
AI’s Transformative Impact on Memory Markets
Morgan Stanley’s Joseph Moore noted that SanDisk views AI as a force that is “fundamentally changing” NAND market dynamics. Inference workload requirements are the primary catalyst. As large language models demand expanded key-value caches and broader context windows, DRAM capacity proves insufficient — prompting NAND to assume a more prominent position in the memory architecture.
Cloud infrastructure is projected to become NAND’s dominant end market before 2026 concludes. SanDisk’s data center business already demonstrates this transformation, exploding 233.4% sequentially to reach $1.47 billion during Q3 FY2026.
Third-quarter results, disclosed April 30, exceeded expectations dramatically. Revenue reached $5.95 billion, representing a 251% year-over-year increase and substantially surpassing the $4.55 billion analyst consensus. Non-GAAP EPS delivered $23.41 compared to expectations of $14.36. Non-GAAP gross profit skyrocketed 1,111.9% year-over-year to $4.7 billion. Additionally, the company eliminated its debt obligations, concluding the quarter with $3.7 billion in cash reserves.
Shares advanced 3.04% on the earnings announcement date and gained an additional 8.25% during the subsequent trading session.
Forward Outlook
Company leadership provided Q4 FY2026 revenue guidance of $7.75 billion to $8.25 billion, with non-GAAP EPS ranging from $30 to $33. Wall Street analysts forecast Q4 EPS of $31.81, representing a 158,950% year-over-year improvement.
QLC Stargate products — undergoing hyperscaler qualification for more than a year — are now anticipated to commence revenue-generating shipments in Q4, providing an additional growth catalyst beyond existing TLC product momentum.
Notwithstanding its impressive performance, SanDisk trades at 34.13 times forward adjusted earnings and 17.17 times sales, both elevated relative to industry benchmarks. Its P/E ratio of 64.5 compares to an industry norm of 44.5. The stock also trades approximately 12% above the consensus analyst price target of $1,863.06.
Among 21 analysts tracking the stock, 18 assign it a “Strong Buy” rating, one recommends “Moderate Buy,” and two advise “Hold.” Morgan Stanley carries an “Overweight” rating with a $1,750 price objective. The highest Street target stands at $3,250.
