Sandisk Corporation (NASDAQ: SNDK) has turned into one of 2025’s standout tech stories. Since being spun out of Western Digital in February, the flash-memory specialist has delivered a near‑parabolic move in its share price – roughly 500% year to date and more than 200% over the last 90 days. [1]
As of the close on December 5, 2025, Sandisk traded around $216–217 per share, up about 1.5% on the day, with an intraday range between roughly $211 and $220 and a market capitalization just over $31 billion. [2]
On the same day, China Renaissance initiated coverage with a Buy rating and an aggressive $322 price target, adding fresh fuel to an already hot narrative around AI‑driven demand for flash memory and data‑center storage. [3]
Below is a detailed, up‑to‑date look at Sandisk stock as of December 5, 2025, including all the key news, earnings, forecasts and analyses that matter now.
Sandisk at a Glance: From WD Spinoff Back to Standalone AI Player
Sandisk (historically stylized “SanDisk”) designs and manufactures flash‑based storage products — from SSDs and memory cards to enterprise and data‑center solutions. [4]
The company’s modern chapter began when Western Digital completed a spin‑off of its flash business in early 2025. On February 24, 2025, Sandisk returned to the Nasdaq as an independent public company, again using its old ticker SNDK. [5]
Since then, Sandisk has rapidly repositioned itself as:
- A leveraged play on AI infrastructure, with fast‑growing cloud and data‑center revenue
- A key supplier of cutting‑edge NAND technologies such as BiCS8 and UltraQLC for hyperscale workloads
- A capital‑intensive manufacturer navigating volatile pricing cycles and heavy fabrication (“fab”) startup costs [6]
Latest Price Action: December 5, 2025 Snapshot
At the close on December 5, Sandisk shares changed hands around $216.66, up about $3.35 (≈1.6%) on the day. The stock traded between $211.00 and $220.06, with intraday volume above 3.1 million shares.
Key performance context from recent data:
- 90‑day return: ~211%
- Year‑to‑date return (2025): ~493%
- Market cap: ~$31 billion
- Trailing GAAP P/E: negative (the company is still loss‑making on a GAAP basis despite improving results) [7]
In other words, Sandisk is trading like a high‑beta, high‑expectation AI infrastructure name: large‑cap in size, but small‑cap in volatility.
Big Structural Catalyst: Sandisk Joins the S&P 500
One of the most important late‑2025 milestones for Sandisk is its addition to the S&P 500 index.
- S&P Dow Jones Indices announced that Sandisk would move out of the S&P SmallCap 600 and into the S&P 500 at the end of November, replacing Interpublic Group. [8]
- Ahead of the change, Sandisk’s stock had already surged more than fourfold, with a market cap around $30–33 billion, making it unusually large for the small‑cap index and a natural candidate for promotion. [9]
- Yahoo Finance’s “Company News for Dec 1, 2025” noted that Sandisk shares gained nearly 4% as the company officially debuted in the S&P 500. [10]
Index inclusion brings forced buying from index funds and ETFs, greater visibility with institutional investors, and often higher trading liquidity — all of which can support valuations, even after a large run‑up.
Earnings and Guidance: From Recovery to Acceleration
Fiscal Q4 2025: Turning the Corner
Sandisk reported fiscal Q4 2025 results on August 14, 2025:
- Revenue:$1.90 billion, up 12% quarter‑over‑quarter and above its own guidance range [11]
- Non‑GAAP EPS:$0.29
- GAAP net loss:$23 million, or –$0.16 per share [12]
- Full‑year 2025 revenue: about $7.36 billion, up ~10% from 2024
- Cloud revenue: up ~195% year over year, driven by hyperscale and AI workloads [13]
For fiscal Q1 2026, Sandisk initially guided to:
- Revenue:$2.10–$2.20 billion
- Non‑GAAP EPS:$0.70–$0.90
This EPS range landed below the roughly $0.95 consensus expectation, largely because of rising fab startup costs — expected to be about $60 million, up from $42 million in Q4. [14]
Investors initially sold the stock off by about 5% on that guidance, highlighting how sensitive sentiment has been to margin dynamics and capex intensity. [15]
Fiscal Q1 2026: Big Beat and Higher Outlook
Fast forward to November 6, 2025, and the tone changed markedly. Sandisk’s fiscal Q1 2026 results and outlook were much stronger than expected:
- Revenue:$2.31 billion, up ~21% sequentially and above prior guidance [16]
- GAAP net income: about $112 million, moving firmly back into profitability [17]
- On an earnings call and subsequent commentary, management highlighted that fab startup costs were already falling, from around $60 million in Q4 to roughly $30 million in Q1, and expected to approach zero in upcoming quarters. [18]
More importantly, guidance blew past expectations:
- Sandisk raised Q2 FY26 outlook to adjusted EPS of roughly $3.00–$3.40, compared with prior Street estimates around $1.8.
- Revenue guidance for the quarter was lifted to approximately $2.55–$2.65 billion. [19]
Unsurprisingly, the stock spiked double digits after this print as investors repriced the earnings power of the business in an AI‑heavy demand environment. [20]
Technology & Strategy: BiCS8, UltraQLC and High Bandwidth Flash
Sandisk’s fundamental story is anchored in its technology roadmap:
- The company is ramping BiCS8, its latest generation of 3D NAND, which underpins a new UltraQLC™ platform and a 256TB NVMe enterprise SSD specifically designed for AI‑driven workloads and hyperscale cloud deployments. [21]
- In August 2025, Sandisk signed an MoU with SK hynix to standardize High Bandwidth Flash (HBF), a memory technology targeted at AI that aims to deliver 8–16x the capacity of HBM (High Bandwidth Memory) at roughly similar cost levels. First HBF samples are planned for 2026, with AI inference devices using HBF expected in 2027. [22]
This roadmap positions Sandisk not just as a commodity NAND supplier, but as a solution provider for AI and high‑performance computing — a key point behind the bullish case.
AI Tailwinds and Sector Context
A broad theme across recent analysis is that AI infrastructure spending is reshaping storage demand:
- A Bank of America note earlier in the fall more than doubled its price target for Sandisk from $59 to $125, pointing to surging AI‑related demand for data‑center storage and higher flash pricing due to constrained supply, particularly in China. [23]
- Subsequent commentary from Citi and Bank of America following strong results from peer Micron Technology further boosted sentiment. Analysts cited improving memory fundamentals, rising NAND pricing and a supportive supply‑demand balance as reasons to raise Sandisk targets into triple‑digit territory. [24]
At the same time, Sandisk itself has been raising NAND prices, including at least three increases in 2025 — over 10% in April, another rise in September for consumer products, and a more aggressive move in enterprise segments. [25]
The combination of:
- Rapid AI and cloud growth
- A still‑tight supply environment in NAND
- A value‑added enterprise SSD and HBF roadmap
has created a powerful earnings‑leverage story — one reason many analysts and momentum investors have piled into the stock despite its volatility.
Recent Volatility: Big Moves in Both Directions
Even as Sandisk rallies, the stock remains highly volatile:
- A recent piece highlighted Sandisk jumping around 9–10% in a single session, despite already being up roughly 500% year to date, framing it as one of 2025’s most dramatic tech turnarounds. [26]
- Another day in November saw the stock drop nearly 20% in one session as investors digested the impact of ongoing fab startup and underutilization costs, even against otherwise strong guidance. [27]
- A broader early‑December risk‑off move in tech left Sandisk down about 5–6% on one day, as high‑momentum names sold off. [28]
- MarketBeat also flagged episodes where Sandisk shares gapped down 3–4%, even as analysts like Cantor Fitzgerald raised their price target from $240 to $300 and maintained an “overweight” rating. [29]
The message is clear: Sandisk has transformed into a crowded, sentiment‑driven trade where news on fab costs, pricing, AI demand or index flows can move the stock sharply in either direction.
What Wall Street Is Saying Now: Price Targets and Ratings
Fresh Coverage: China Renaissance Buy, $322 Target
On December 5, 2025, China Renaissance launched coverage of Sandisk with a Buy rating and a $322 price objective — implying substantial upside from the ~$216 level at Friday’s close. [30]
The firm framed Sandisk as a prime beneficiary of AI‑driven flash demand and a leading supplier of next‑generation NAND technology.
Broader Analyst Consensus
Different data providers show varying “consensus” numbers, reflecting how quickly sentiment has shifted:
- MarketBeat lists an average 12‑month price target around $201, based on roughly ~22 analysts, with estimates ranging from $32 at the low end to $322 at the high end. At the time of that data, this implied mid‑single‑digit downside from then‑current prices. [31]
- A Fintel/Nasdaq‑tracked consensus was revised in mid‑November to about $259 per share, more than doubling from a prior average near $112 — a sign of how rapidly analysts have been chasing the stock higher as fundamentals improved. [32]
- TradingView and FactSet‑based sources show a cluster of targets around $260–270, with typical ranges between about $220 and $314. [33]
- A recent Yahoo/Argus quantitative report pegged a more cautious target of roughly $216, effectively in line with the current share price. [34]
Put together, the latest picture looks like this:
- Ratings: Overall skewed toward Buy / Overweight
- Targets: Wide range, from low double digits (legacy or highly conservative estimates) to $322 at the top end
- Implied positioning: Many analysts still see upside, but some valuation‑sensitive models are starting to view the stock as “fully valued” after the huge 2025 run
Valuation Check: Hot Momentum vs. Early‑Cycle Earnings
Recent valuation work has raised a natural question: is it too late to get in?
- A widely circulated piece noted that Sandisk’s share price had climbed roughly 440% year to date to ~$194 before a modest pullback, while fundamentals — though improving — were still catching up. [35]
- Another analysis observed that at a recent close near $213, the stock had delivered a ~211% gain over 90 days and a ~493% gain in 2025, putting it firmly into “momentum outlier” territory. [36]
- Robinhood data show a negative trailing P/E (around –18), underscoring that GAAP profitability is only just returning as startup and underutilization costs roll off. [37]
The bull argument is that earnings are inflecting sharply upward, with Q2 FY26 guidance pointing to multi‑dollar EPS and the potential for strong operating leverage as fab costs normalize. [38]
The bear (or at least cautious) view is that a lot of that growth is already priced in, given:
- The extreme YTD share price move
- Ongoing cyclicality in memory markets
- The risk that AI‑related spending normalizes after an initial boom
Key Risks to Watch
For all the excitement, Sandisk is not without meaningful risks:
- Memory Cycle Volatility
NAND and DRAM historically move in boom‑bust cycles. Even if AI demand stays strong, capacity expansions or slower end‑market growth could pressure pricing and margins later in the decade. - Fab Startup and Underutilization Costs
Recent quarters were heavily impacted by tens of millions of dollars in fab startup and underutilization costs. While management expects these to trend toward zero, any delays, cost overruns or new fab projects could reintroduce margin headwinds. [39] - Execution on New Technologies
The bullish thesis assumes successful ramp of BiCS8, UltraQLC and HBF — all sophisticated technologies that must be qualified by hyperscale and enterprise customers. Any hiccup in yields, performance or adoption could dent the growth narrative. [40] - Valuation & Sentiment Risk
With a multi‑hundred‑percent rally behind it and heavy attention from traders, Sandisk is now highly sensitive to any disappointment in earnings, guidance or macro data. Recent one‑day swings of 10–20% underline that risk. [41]
What Investors Should Watch Next
Looking ahead from December 5, 2025, key watchpoints for Sandisk stock include:
- Q2 FY26 results and guidance – Will management deliver on the elevated revenue and EPS bar it set after Q1, and what does it say about the second half of fiscal 2026? [42]
- Progress on fab cost normalization – Confirmation that startup costs are indeed fading and underutilization charges are under control could materially support margins. [43]
- AI and cloud demand signals – Any commentary from hyperscalers, chipmakers or memory peers that suggests AI infrastructure spending is accelerating (or slowing) will likely move SNDK. [44]
- Further index and ETF flows – With the S&P 500 inclusion still fresh, tracking how passive and factor funds build positions could help explain short‑term price moves. [45]
- Additional analyst revisions – New coverage like China Renaissance’s Buy/$322 call, or future updates from large banks and research shops, can influence sentiment given how wide current target ranges are. [46]
Bottom Line
As of December 5, 2025, Sandisk sits at the intersection of:
- A powerful AI and cloud infrastructure uptrend
- A classic memory‑cycle recovery
- A high‑expectation valuation after one of the market’s most dramatic runs this year
The company has delivered strong revenue growth, a return to profitability, and aggressive guidance, while pushing an ambitious roadmap in BiCS8, UltraQLC and High Bandwidth Flash. At the same time, its share price now embeds significant optimism about that future.
For traders, Sandisk is likely to remain a high‑volatility AI momentum name. For longer‑term investors, the key question is whether the earnings trajectory and technology edge can justify today’s price — and beyond — through the next phase of the memory cycle.
