SNDK stock sank in after-hours trading Wednesday after Sandisk delivered a strong fiscal fourth-quarter earnings report but issued revenue guidance that fell short of Wall Street expectations. The shares dropped about 4% following the announcement, adding pressure to one of the market’s strongest performers in 2026.
Why SNDK Stock Fell After a Powerful Earnings Beat
Sandisk, the flash memory and storage manufacturer that spun off from Western Digital in February 2025, reported fiscal fourth-quarter revenue of $8.79 billion. That result exceeded the consensus estimate of $8.64 billion.
The company also posted adjusted earnings per share of $39.25, well above analyst expectations of $34.37. Sandisk said revenue growth was driven by a combination of stronger shipment volumes and higher pricing. Approximately one-third of the increase came from greater volumes, while two-thirds reflected pricing gains.
Despite those impressive results, investors focused on the company’s forward outlook. Sandisk expects fiscal first-quarter revenue between $10.3 billion and $10.8 billion. Analysts had projected revenue of approximately $11.16 billion, creating a sizable gap between expectations and the company’s forecast.
Critical Revenue Guidance Disappoints Investors
Sandisk’s adjusted earnings outlook was closer to expectations. The company projected adjusted earnings per share of $44 to $46 for the current quarter, compared with the analyst estimate of $45.58.
However, the revenue forecast appeared to overshadow the earnings beat. For a stock that has climbed nearly 490% since the beginning of the year, investors are demanding continued acceleration. Even a forecast that suggests substantial growth can trigger selling when it does not match an exceptionally optimistic outlook.
- Fiscal Q4 revenue: $8.79 billion
- Fiscal Q4 adjusted EPS: $39.25
- Fiscal Q1 revenue guidance: $10.3 billion to $10.8 billion
- Fiscal Q1 adjusted EPS guidance: $44 to $46
- Additional share repurchase authorization: $14 billion
Sandisk’s Explosive AI Infrastructure Opportunity
The broader investment case for Sandisk remains connected to the rapid expansion of artificial intelligence infrastructure. Data centers require massive amounts of high-performance memory and storage to support AI models, servers, and increasingly complex applications.
Memory and storage have emerged as important bottlenecks in the AI hardware supply chain. That trend has helped fuel demand for Sandisk products and contributed to the company’s extraordinary stock market performance this year.
Earlier this week, Sandisk shares also benefited from news involving SK Hynix. The two memory makers released a hardware blueprint intended to improve the speed and efficiency of AI chips. By promoting a shared standard for high-speed memory, the companies hope to reduce data center costs and support faster deployment of advanced AI applications.
The collaboration reinforces Sandisk’s role in the growing AI hardware ecosystem, although it does not eliminate concerns about valuation, cyclical demand, or future pricing pressure.
Massive Buyback Adds Support
Sandisk also approved an additional $14 billion share repurchase authorization. Buybacks can support earnings per share by reducing the number of shares outstanding, while also signaling that management believes the company has significant financial flexibility.
The move may reassure long-term investors, but it did little to offset the immediate disappointment surrounding the revenue forecast. After such a steep rally, traders may be more sensitive to any indication that growth could moderate.
What Analysts Are Saying About SNDK Stock
Wall Street sentiment toward Sandisk remains notably positive. According to the Yahoo Finance report, analysts hold 25 Buy ratings and five Hold ratings, with no Sell recommendations. The average price target is slightly above $2,400.
That bullish consensus reflects confidence in long-term AI infrastructure demand, memory pricing, and Sandisk’s position in the storage market. Still, analyst targets can change quickly when a company’s guidance misses expectations or when a stock experiences an unusually rapid advance.
For now, SNDK stock presents a mixed picture: excellent recent execution, powerful AI-related demand, and a large buyback on one side; elevated expectations and a disappointing revenue forecast on the other. Investors will likely watch upcoming quarterly results, pricing trends, shipment volumes, and developments in the AI memory market for evidence of whether the company’s momentum can continue.
