Investment Thesis For SanDisk (SNDK)
Sandisk on Thursday said it expects revenue to grow at a mid-to-high-teens percentage rate from fiscal years 2028 to 2030, encouraged by strong demand amid rapid AI infrastructure buildout.
The company said the projection is in line with growth in the amount of storage capacity it produces, a metric the industry calls "bit growth."
Speaking at Sandisk's Investor Day, finance chief Luis Visoso said the company expects adjusted gross margins to remain at around 80% over the same period.
By laying out a multi-year framework tied to committed customer volumes, Sandisk is seeking to show that its recent growth can be sustained, rather than reflecting a temporary demand spike.
Under its new business model, Sandisk has signed agreements with eight customers, which include three U.S. hyperscalers, covering about half of its storage output in fiscal 2027 and two-thirds in fiscal 2028.
Chief Technology Officer Alper Ilkbahar said Sandisk has taped out its first memory die — or the individual silicon chip that stores data — for its High Bandwidth Flash technology, and is working to deliver initial samples to customers developing AI inference devices next year.
HBF is a memory chip that combines the speed of high-bandwidth memory used with AI processors and the capacity of flash memory, helping data centers meet the growing memory demands of AI inference — the data crunching that occurs when a user queries a chatbot.
The outlook builds on Sandisk's financial results reported last week, when it also forecast first-quarter revenue above analyst estimates, citing rising demand for memory chips used in AI data centers.
Goldman Sachs, in a research note dated August 13, highlighted that SanDisk Corp. not only provided long-term financial guidance that significantly exceeded market expectations (80% gross margin, 75% operating margin) but also made a bold commitment to return 100% of excess free cash flow to shareholders. Furthermore, the company's next-generation HBF (High Bandwidth Flash) technology roadmap for AI inference provides substantial upside potential.

Investment Thesis For SanDisk (SNDK) :
Sandisk's long-term financial guidance is exceptionally bullish, signaling a structural shift in its business model and strong conviction in the sustained demand driven by the AI infrastructure buildout. The company is projecting industry-leading growth and profitability by securing long-term customer commitments, moving away from the volatile spot market that historically defined the memory industry.
Key Information
Here is a breakdown of the three major components of Sandisk's announcement:
1. Revenue Growth Outlook: Mid-to-High-Teens CAGR (FY2028-2030)
What it means: Sandisk expects its annual revenue to grow at a compound annual growth rate (CAGR) of approximately 14% to 17% over the three-year period from fiscal 2028 to 2030. This is a very high growth rate for a mature hardware component company.
The Driver: "Bit Growth." The company explicitly links this revenue projection to "bit growth," which is the industry metric for the total amount of storage capacity (in bits) shipped. This means Sandisk expects to sell significantly more storage capacity each year, not just raise prices.
The Catalyst (AI Infrastructure): This expected demand surge is directly attributed to the rapid buildout of AI data centers. These centers require massive amounts of storage for training datasets, model checkpoints, and, increasingly, for AI inference—the process of using a trained AI model to answer queries, which generates enormous amounts of data. This makes Sandisk's projection a direct play on the AI theme.
2. Profitability Target: 80% Adjusted Gross Margins
What it means: Sandisk's finance chief guided that the company expects to maintain an adjusted gross margin of around 80% over the same period (FY2028-2030).
Context: This is an extremely high margin, more comparable to a software or fabless semiconductor company (like NVIDIA or AMD) than a traditional memory manufacturer, which often sees margins fluctuate wildly between 20% and 60%. For example, a major competitor like Western Digital has historically had gross margins in the 25-35% range.
How Achievable? This high margin is only achievable under Sandisk’s new business model, which relies on long-term, committed contracts with customers (see point 3), providing predictable pricing and volume. The Goldman Sachs analyst note from August 13 highlighted that this 80% margin "significantly exceeded market expectations" 1.
3. The New Business Model: Long-Term Customer Commitments
The Strategy: Sandisk has signed long-term agreements with eight major customers, including three U.S. hyperscalers (e.g., Amazon, Google, Microsoft).
The Guarantee: These contracts cover about half of Sandisk's storage output in FY2027 and two-thirds in FY2028.
The Implication: This fundamentally changes Sandisk's business. Instead of being a price-taker in the volatile memory spot market, Sandisk becomes a strategic supplier with locked-in demand and pricing. This provides the visibility needed to make bold revenue and margin projections. The "bit growth" is essentially pre-sold.
Key Risk
Execution on Technology Roadmap: The entire 80% margin and high growth narrative hinges on the successful commercialization of High Bandwidth Flash (HBF) technology and other high-value products for AI inference. If there are delays, yield issues, or if competing technologies (e.g., from Samsung, SK Hynix, or Micron) prove superior, Sandisk may be forced to sell more of its older, lower-margin NAND flash into the commodity market, missing its targets.
