TLDRs:
- Sandisk falls after strong earnings fail to meet elevated expectations.
- AI-driven storage boom lifts results but pressures valuation multiples.
- $6 billion buyback unable to offset post-earnings selling pressure.
- Investors question sustainability of AI-fueled NAND pricing strength.
Sandisk (SNDK) slipped around 6% in after-hours trading following its latest earnings release, despite delivering a quarter that significantly exceeded Wall Street expectations on both revenue and profitability.
The decline highlights a growing tension in the market: even exceptional performance is no longer enough to justify further upside after the stock’s historic AI-driven rally.
The flash-storage giant, a key player in NAND memory used across data centers, smartphones, and AI infrastructure, reported fiscal Q3 revenue of $5.95 billion, marking a staggering 251% year-over-year increase. Adjusted earnings per share reached $23.41, well ahead of analyst estimates. However, investors appeared more focused on valuation concerns than headline beats.
Massive Growth Across Segments
Sandisk’s performance was powered by extraordinary strength in its data center and edge storage divisions. Data center revenue surged 645% year-over-year to $1.47 billion, while edge computing-related storage climbed 295% to $3.66 billion. Even consumer storage, traditionally a more stable but slower-growing segment, rose 44% year-over-year.
Gross margins expanded dramatically to 78.4%, compared to just 22.5% a year earlier, reflecting improved pricing power and a strategic shift toward high-margin enterprise customers. The company attributed this transformation to rising demand for AI-focused storage infrastructure, which continues to strain global supply chains.
Despite these strong figures, consumer revenue showed a 10% sequential decline, suggesting uneven momentum across business lines.
AI Demand Fuels Transformation
Chief Executive David Goeckeler described the quarter as a “fundamental inflection point,” emphasizing Sandisk’s transition toward higher-value enterprise and AI-driven markets. The company also disclosed progress on five long-term customer agreements under its New Business Model framework, signaling deeper integration into AI infrastructure supply chains.
Sandisk’s positioning within the AI ecosystem has been a major catalyst for its stock performance over the past year. Shares have surged more than 3,000% in the last 12 months as investors rushed into memory and storage plays tied to artificial intelligence expansion across hyperscale data centers.
However, such rapid gains have dramatically raised expectations, making even strong results insufficient to sustain upward momentum.
Buyback and Forecast Unimpress Market
To reinforce shareholder value, Sandisk announced a $6 billion share buyback program. While typically supportive of stock prices, the announcement failed to offset post-earnings selling pressure. The buyback is flexible and can be paused or canceled at management’s discretion, limiting its immediate impact on sentiment.
The company also issued an optimistic outlook for fiscal Q4, projecting revenue between $7.75 billion and $8.25 billion, alongside adjusted earnings of $30 to $33 per share. Despite this, investors appeared reluctant to extend valuations further after such a steep rally.
Analysts have echoed this cautious tone. While some, including Morgan Stanley, raised price targets to $1,100, they emphasized that the key question is not near-term demand but long-term durability of AI-driven pricing power.
Valuation Concerns Dominate Outlook
The broader storage sector has benefited from AI demand, with peers such as Western Digital and Seagate also issuing strong guidance. Yet volatility remains elevated as investors weigh whether current pricing levels can be sustained if AI infrastructure spending slows or supply increases faster than expected.
Sandisk itself acknowledged risks including pricing volatility, supply chain constraints, and reliance on major partners. With the stock already in parabolic territory, the latest pullback suggests markets are increasingly sensitive to even minor shifts in sentiment.
Ultimately, while Sandisk continues to deliver exceptional operational performance, Thursday’s selloff underscores a shifting narrative: in today’s AI-driven rally, strong earnings alone may no longer be enough to keep momentum alive.
