On August 13, Eastern Time, storage company SanDisk Corp. presented a long-term commitment during its 2026 Investor Day, outlining ambitious financial targets for the coming years. The company projected revenue growth of 15% to 19% annually for fiscal years 2028 to 2030, targeting non-GAAP gross margins of approximately 80%, operating margins of around 75%, and adjusted free cash flow margins of about 50%. Additionally, management pledged to return all excess cash after reinvestment to shareholders. The stock surged over 15% during the session, reclaiming the $1,500 mark and lifting peers like Micron. Year-to-date, the stock, spun off from Western Digital, has risen more than sixfold. From its post-spinoff low in February 2025, the gain exceeds 30 times in less than 18 months.
Standing at a peak, SanDisk Corp. is betting big on a new business model (NBM) and AI inference hardware (such as HBF technology) to reshape pricing power. However, investors who remember the storage industry's painful cycles remain cautious. Just a week ago, despite reporting a 372% year-over-year revenue surge and 84.6% gross margins for the fourth quarter, the market panicked over weaker-than-expected first-quarter guidance, fearing a "cycle peak," causing the stock to drop over 40% from its highs.
A longtime semiconductor analyst noted that the real purpose of this Investor Day is for SanDisk Corp. to break free from the "commodity stock" label and reposition itself as a long-term AI infrastructure supplier. The key question is whether long-term contracts can lock in high margins, avoiding the 2023 disaster. Chairman and CEO David Goeckeler stated that since the spinoff from Western Digital over a year ago, the company has paid off all long-term debt, holds over $6.5 billion in cash and marketable securities, and has scaled quarterly revenue to an annualized $36 billion, with data center business contributing $12 billion annually.
Where to Start
With financial independence achieved, management aims to address the root cause of valuation discount: cyclicality. The New Business Model (NBM) is SanDisk Corp.'s strategy to tackle this cycle. Essentially, it transforms the traditional spot-market storage business into a structure resembling long-term contracts. Goeckeler explained that NBM involves signing supply agreements with major customers for 1 to 5 years, with a weighted average of over 4 years, locking in product mix, shipment volumes, and pricing commitments monthly, backed by financial guarantees. CFO Luis Visoso revealed that the first batch of agreements was signed in January, with negotiations typically taking about three months. So far, eight customers have signed, including three U.S. hyperscalers (names undisclosed). Two customers have already expanded their contracts, and the company is negotiating longer terms with others. By fiscal 2027, about 50% of bit shipments are expected under NBM, rising to two-thirds by fiscal 2028.
Pricing details are crucial for investors. Visoso noted that contract pricing is partially fixed with upper and lower bounds, and even at the lowest contracted price, gross margins remain at 80%. He added details on guarantee mechanisms: for a three-year contract, the average financial guarantee as a percentage of total contract value (TCV) doubles after two years. A Bank of America analyst directly questioned why these long-term agreements would differ from historical failures during downturns. CEO Goeckeler did not directly answer but joked, "The industry has messed up more than once, but we believe our efforts will make this time different." He argued that the quality of customer relationships has changed, noting that in 2000, he dealt with procurement departments, while now he meets with CEOs. "You're not in this business, so you can't understand the fundamental changes happening. I don't think these CEOs are signing long-term contracts just to bluff and later exit."
First HBF Tape-Out Completed, But Monetization Still Far Off
Beyond long-term contracts, SanDisk Corp. frames its supply-side story as "capital efficiency." The company disclosed that from 2021 to 2025, its manufacturing alliance with Kioxia accounted for only 13% of global NAND capital expenditure but produced 29% of NAND output. Technologically, it has iterated five nodes in nine years, with average bit density per wafer increasing 54% per generation and productivity growing at a 27% CAGR. Management emphasized they would not "immediately ramp up new nodes," avoiding the 2023 oversupply that led to industry-wide losses. This statement serves as a discipline commitment to investors and a signal to competitors like Samsung and SK Hynix. In the 2023 downturn, Samsung's semiconductor division suffered an operating loss of about $11 billion, while SK Hynix and Micron reported record losses, with NAND wafer prices falling below cash costs.
On product roadmaps, SanDisk Corp. introduced BiCS9 QLC, using a CBA (CMOS Direct Bonded Array) modular architecture to combine mature BiCS8 storage arrays with BiCS10 wafers, extracting AI workload performance with minimal additional capital expenditure. BiCS10 QLC offers 60% higher bit density than BiCS8, targeting performance and energy efficiency benchmarks. The company estimates the enterprise data center flash market will reach 1.2 zettabytes by 2030. The bigger growth driver is High Bandwidth Flash (HBF), often compared to "HBM moment for NAND." CTO Alper Ilkbahar showed the first HBF chip tape-out photo, stating that tape-out is complete, with first inference product samples expected next year, currently in deep co-development with multiple customers. Google DeepMind researcher Xiaoyu Ma recently noted at the Flash Memory Summit (FMS) that the "memory crisis" in large model inference could be addressed through three angles: inference specialization, memory heterogeneity, and hardware-software co-design, with the second approach being HBF's hardware revolution.
SanDisk Corp. claims HBF technology can break AI's "memory bottleneck," offering read bandwidth comparable to HBM but with 8 to 16 times the capacity. First HBF samples are expected in 2027. If realized, NAND flash would extend beyond storage to directly serve high-performance AI inference. The HBF ecosystem alliance currently includes Google, Meta, SK Hynix, and Tenstorrent. Notably, HBF is still in the "pie-in-the-sky" phase and is not included in SanDisk Corp.'s financial model. All fiscal 2028-2030 guidance excludes HBF contributions. This is both a "free option" for bulls and a story without earnings for now. During the Q&A session, questions about HBF's future pricing and capital expenditure impact were met with management stating they had no specific information to disclose.
Bull vs. Bear: The Cycle Law Remains Unrefuted
At the meeting, an analyst defended the company, arguing that the stock could earn back a small portion of its current value in three years, with HBF's story not yet priced in. Yet the answer was clear to all: the market sees profits but doubts their sustainability. Discussions with multiple investors revealed key bearish arguments: First, the cycle law remains unrefuted. SanDisk Corp.'s three-year model assumes revenue grows with shipment volumes without price declines, but historically, price drops are the norm in NAND. While SanDisk disciplines supply, it cannot guarantee competitors like Samsung, SK Hynix, and Micron won't use price wars to gain market share. Another variable is YMTC; Counterpoint Research data shows that in Q2 this year, YMTC's NAND flash shipments surpassed U.S. rival Micron and Japan's Kioxia, trailing only Samsung and SK Hynix.
Second, demand cracks are appearing. In the Q4 report, consumer business revenue fell 32% sequentially, indicating price increases are affecting price-sensitive demand. SanDisk Corp. highlighted its 351,000 sales points globally to show commitment to consumer business, calling it a "ballast" during industry troughs. But as resources shift toward high-growth data center operations, consumer demand trends will be a key indicator in coming quarters.
Third, NBM long-term contracts have not been tested in a downturn. Financial guarantees are well-intentioned, but historical precedents exist where long-term agreements were renegotiated or torn up during price crashes, leading to legal disputes. Management also confirmed that some customers still prefer traditional, short-term business models.
Fourth, the double-edged sword of key customer dependence. Three U.S. hyperscalers are the main NBM contract partners, and data center revenue share is rising. Management views this as a strategic asset, but investors see it as concentration of pricing power and demand volatility tied to a few companies' AI capital expenditure. Regarding a second growth engine outside data centers, management mentioned "physical AI" (robotics, smart terminals) as a promising area but provided no details, meaning near-term risk concentration remains unhedged.
SanDisk Corp.'s 80% gross margin outlook is nearly double the industry's stable period benchmark, but the market remains unconvinced. Facing the "commodity" label, the CEO retorted, "If you think it's just a commodity, try it yourself. You don't know the technical accumulation required in this industry." However, the storage industry has historically cycled through phases of supply shortage, expansion, overcapacity, and production cuts. This cycle, AI's demand for high-bandwidth, large-capacity storage gives SanDisk Corp. management hope to change the game. But whether NBM contracts can withstand a future downturn, whether the HBF ecosystem will deliver on large-scale inference, and whether SanDisk Corp. can shed its "cyclical stock" label to sustain long-term value – the market's test has only just begun.
