Sandisk Corporation (SNDK) drops 5.9% after earnings rally
May 12, 20266 min read
Key Takeaway
Sandisk Corporation (SNDK) dropped 5.9% in Tuesday trading as investors locked in gains after a massive post-earnings surge. The selloff appears driven by profit-taking and a valuation reset, not a new business setback, after Sandisk posted blowout Q3 results, raised guidance, and showed surging datacenter demand. For investors, the move signals that the stock remains fundamentally strong but highly extended.
Sandisk Corporation (SNDK) drops sharply in Tuesday trading, falling 5.94% to $1,455.61 as of 10:05 ET. The move stands out because it comes after one of the strongest earnings reports in the memory space, which points to profit-taking and a post-earnings reset rather than a fresh company-specific blowup.
Key Takeaways
•
SNDK was down 5.94% at $1,455.61 in regular trading on May 12, even after a powerful run since its April 30 earnings report.
•
The most concrete driver is a post-earnings repricing after Sandisk reported Q3 2026 revenue of $5.95B, non-GAAP EPS of $23.41, and Q4 non-GAAP EPS guidance of $30.00 to $33.00.
•
Analysts reinforced the bullish backdrop after earnings, with Mizuho raising its price target to $1,625 on May 6 and Susquehanna lifting its target to $2,000 on May 1.
•
Financially, Sandisk is no longer trading like a plain commodity storage name. Datacenter revenue reached $1.467B in Q3, up from $440M in Q2 and $197M a year earlier.
•
For investors, the selloff looks more like volatility after a steep rally than a clear break in the business story, but the stock still carries a rich 52.9 P/E and a very high bar.
Why Sandisk Corporation Stock Is Dropping Today
The cleanest explanation for today’s decline is that SNDK is giving back part of a huge post-earnings surge. There was no clear new earnings release, guidance change, major filing, or analyst downgrade tied to May 12. Instead, the stock is trading after an extraordinary April 30 report that pushed expectations much higher in a very short time.
That matters because sharp gains often create their own pressure. After a stock rises this fast, even strong names can slip as traders lock in gains, rotate into peers, or reset positions. In Sandisk’s case, recent headlines still focused on the company’s massive rally, including a report noting the stock had risen 82% over the last 30 days alongside other memory names.
There is also a broader sector piece here. Memory chip stocks have been moving hard as investors chase AI infrastructure exposure beyond GPUs. Sandisk sits in that trade through NAND flash, enterprise SSDs, and high-capacity storage for datacenter workloads. When that group gets crowded, the tape can turn rough even without a company-specific headline. The market has a habit of treating hot themes like a spring. The tighter it coils, the sharper the snapback.
Sandisk Q3 2026 Earnings Still Explain the Stock's Violent Repricing
The April 30 quarter was the event that changed the stock’s trajectory. Sandisk reported Q3 2026 revenue of $5.95B, up 97% sequentially and 251% year over year. Non-GAAP diluted EPS came in at $23.41 versus a consensus estimate of $14.66, a 59.7% surprise. GAAP diluted EPS was $23.03.
Just as important, profitability was exceptional. Gross margin reached 78.4%, and non-GAAP operating income hit $4.218B. Then Sandisk raised the stakes again with Q4 2026 guidance for revenue of $7.75B to $8.25B and non-GAAP EPS of $30.00 to $33.00.
Those are not ordinary numbers for a storage company. They tell the market that Sandisk’s earnings power has moved higher, at least for now, because pricing improved and the business mix shifted toward more valuable customers. The company also said datacenter revenue jumped 233% sequentially, which gives the AI-storage narrative real weight instead of marketing gloss.
The earnings history supports that momentum. Sandisk has beaten EPS estimates in each of its last six reported quarters with available comparisons. Before the April blowout, it posted $6.20 against a $3.54 estimate in January. That kind of streak tends to pull in momentum investors fast, but it also leaves the stock vulnerable when buyers pause.

How Sandisk Corporation's Fundamentals Look After the Move
Even after Tuesday’s decline, Sandisk still trades at 52.9 times earnings. That is a demanding multiple for a company in a cyclical memory market, even one posting explosive growth. Put simply, the market is no longer paying for a rebound alone. It is paying for a more durable step-up in margins, pricing, and datacenter relevance.
The bull case has real support. Datacenter revenue reached $1.467B in Q3 2026, up from $440M in Q2 2026 and $197M in Q3 2025. That is a major mix shift. It means Sandisk is getting more exposed to enterprise and AI-linked demand, where pricing and customer commitments can be stronger than in consumer storage.
Balance sheet quality also helps the story. Sandisk highlighted a zero-debt balance sheet, strong cash generation, and a share repurchase authorization. Those facts matter because they give the company room to invest and return capital without leaning on leverage. In a cyclical industry, a clean balance sheet is not glamorous, but it is useful when conditions turn.
Still, there is a catch. The stock’s 52-week range runs from $35.79 to $1,600, which shows how extreme the rerating has been. A move of that scale can detach short-term trading from even strong fundamentals. Great business momentum and a stretched stock can exist at the same time. Wall Street does that all the time, usually with a straight face.
Analyst Targets, AI Storage Demand, and the Outlook for SNDK
Analysts have largely backed the new narrative since earnings. Mizuho raised its price target to $1,625 on May 6 from $1,220. Bernstein lifted its target to $1,700 on May 4. On May 1, Susquehanna raised its target to $2,000, Raymond James moved to $1,470 from $725, and Jefferies lifted its target to $1,400 from $100. The analyst consensus still sits at Buy, with 12 buy ratings and 3 hold ratings.
That wave of target increases helps explain why the stock had become so extended heading into today. When price targets chase a stock higher after a blowout quarter, they validate the move, but they also confirm how much good news is already in the price.
The business backdrop remains favorable. Sandisk has been pushing higher-capacity NVMe products and highlighted its UltraQLC platform, including a 256TB NVMe SSD aimed at AI-driven and hyperscale workloads. Combined with higher pricing and stronger datacenter demand, that product mix gives Sandisk a better competitive position than the old view of it as a plain consumer-storage vendor.
News sentiment also reflects that shift. SNDK carried a 7-day sentiment score of 0.8055, with the trend marked as improving. That is firmly positive. However, positive sentiment after an 82% 30-day run can cut both ways. It supports the long-term story, but it also raises the odds of abrupt pullbacks when traders decide the easy money has been made.
The practical read is simple. Sandisk still has strong operating momentum, but the stock now trades like a premium AI infrastructure name, not a discounted memory cyclical. That can work if Q4 lands near the top of guidance. It can also punish any sign of slowing growth or weaker pricing.
Sandisk’s drop today looks tied to a post-earnings reset after an extraordinary rally, not to a fresh crack in the core business. The company’s numbers remain powerful, but with SNDK near the top of its range and carrying a premium valuation, the stock has become less forgiving even as the fundamentals improve.
SNDK is falling mainly because traders are taking profits after a huge post-earnings rally. There was no new company-specific negative headline on May 12, so the move looks like a valuation reset.
+Should I buy SNDK stock now?
The article suggests the business outlook is still strong, but the stock is expensive and volatile after a steep run. Long-term investors may like the fundamentals, but short-term buyers should be cautious about chasing it here.
+Did Sandisk miss earnings or cut guidance?
No. Sandisk recently reported strong Q3 2026 results and raised Q4 guidance, which is why the stock had rallied so sharply before today's pullback.
+Is this SNDK drop a sign the company is weakening?
Not based on the article. The decline looks more like normal post-rally volatility than a sign of weakening fundamentals, especially with datacenter revenue and analyst targets still moving higher.
