After SanDisk's Investor Day, the stock rose 15%, reflecting a positive market response.
Goldman Sachs maintained a Buy rating and a $2,200 price target in its report released on August 13, noting that SanDisk’s disclosed long-term financial targets significantly exceeded market expectations: revenue CAGR in the mid-to-high double digits from FY28 to FY30, gross margin of 80%, operating margin of 75%, and free cash flow margin above 50%. Additionally, management plans to return 100% of excess free cash flow to shareholders, with a new share repurchase authorization of $14 billion.
This goes beyond the traditional narrative of NAND manufacturers. Goldman Sachs believes that SanDisk is reshaping revenue visibility through NBMs (long-term customer agreements) and unlocking incremental growth in the AI inference market through HBF (high-bandwidth flash) technology, yet the market has not fully priced in these two changes.
80% gross margin redefines the profitability ceiling for NAND
SanDisk's long-term financial targets presented at Investor Day have prompted the market to reassess the profitability potential of its NAND business. Between FY28 and FY30, the company expects revenue growth in the high single to low double digits, an 80% gross margin, a 75% operating margin, and an adjusted free cash flow margin above 50%, with capital intensity in the low single digits. These figures are supported by the NBMs framework, featuring a weighted average contract term of approximately four years, near-term fixed pricing, and a two-way protection mechanism setting price floors and ceilings for future periods. Even under the price floor scenario, gross margins remain at 80%.
To date, SanDisk has signed contracts with eight customers, totaling approximately $94 billion in contract value, with $91 billion in remaining performance obligations and approximately $16.5 billion in financial guarantees. Approximately 50% and 67% of planned capacity for FY27 and FY28, respectively, are covered by NBMs. Goldman Sachs noted that the market’s previous pricing logic based on NAND cyclicality needs recalibration, but the true impact of long-term agreements will take time to materialize, representing the current key uncertainty.
Tens of billions in buybacks are reshaping shareholder return logic
Return of capital was another major highlight of this Investor Day. Management clearly outlined three capital allocation priorities: reinvesting in the business to maintain technological leadership, maintaining a strong balance sheet (zero debt and ample cash), and returning 100% of excess free cash flow to shareholders. The company previously authorized a $6 billion share repurchase program (approximately $4.5 billion already executed) and has now added a further $14 billion authorization, bringing the total remaining repurchase capacity to approximately $15.5 billion.
Goldman Sachs believes that this buyback scale leads its peers and significantly exceeds prior market expectations. For a semiconductor company still in a phase of growth and expansion, using 100% of excess FCF for buybacks reflects management’s confidence in its cash flow generation capabilities.
HBF technology is a call option on the AI inference market.
SanDisk’s technology roadmap provides another layer of upside potential. The core NAND roadmap is progressing steadily, with BiCS9 and BiCS10 representing the latest generations, while BiCS11 to BiCS13 are in various stages of development. Goldman Sachs views this as SanDisk’s foundation, but the true incremental upside comes from HBF technology.
HBF (High-Bandwidth Flash) is designed for AI inference scenarios, where long contexts and reasoning chains in agent-based AI workloads significantly increase memory bandwidth demands. Management identifies KV Cache as the critical working memory during the inference decoding phase, projected to account for approximately 35% of the 1.2 ZB AI data center TAM by 2032.
SanDisk's simulation data shows that the HBF-only architecture requires only half the GPU capacity of an HBM-only architecture for the same token output, implying higher GPU utilization and capital efficiency. The first HBF product has tape-out, with initial samples expected to ship in CY27. If HBF gains widespread adoption in the AI inference market, SanDisk will gain a completely new growth curve independent of the traditional NAND cycle.
Efficient manufacturing is the moat for long-term profits.
Beyond NBMs, repurchases, and HBF, SanDisk has another structurally undervalued advantage: manufacturing efficiency. Through its joint venture with Kioxia (extended through 2034), SanDisk maintains control over the entire manufacturing stack. Management noted that from 2021 to 2025, SanDisk and Kioxia accounted for 29% of the industry’s bit output but only 13% of the industry’s capital expenditures. On average, the industry requires 2.7 times the capital investment per additional exabyte of output compared to SanDisk.
This efficiency advantage enables SanDisk to achieve mid- to high-double-digit bit growth with only mid-single-digit capital intensity. Under the dual drivers of NBM price floors and HBF unlocking the AI incremental market, manufacturing efficiency acts as an amplifier for profitability.
Goldman Sachs' 12-month price target for SanDisk is $2,200, based on a 20x P/E multiple applied to normalized EPS of $110. The current stock price of approximately $1,344 implies a 64% upside potential.
