Sandisk Corp (SNDK): Citi reiterates Buy on Sandisk and raises its target to US$2,500 as AI-led SSD demand supports tight NAND pricing through CY27.

Overview

This is Citi's earnings read-through from Micron for Sandisk. Citi argues that stronger memory-market pricing, structural NAND supply limits and AI-driven enterprise SSD demand reinforce its positive view of Sandisk, leading it to reiterate Buy, lift estimates and raise the target price to US$2,500.

Core views

Citi interprets Micron's better-than-expected F3Q26 results and F4Q26 guidance as further evidence of an unusually strong NAND market. Micron reported May-quarter sales of US$41.5 billion and non-GAAP EPS of US$24.82, versus Citi estimates of US$35.5 billion and US$19.98, respectively; gross margin was 84.6% versus Citi's 80.6% forecast. Its August-quarter guidance of US$50.0 billion of sales, US$30.68 of non-GAAP EPS and 85.7% gross margin also exceeded Citi estimates of US$42.0 billion, US$24.27 and 82.0%. Citi attributes the read-through to tight NAND industry conditions, favorable mix and sharp pricing improvement. The central thesis is that NAND supply-demand conditions should remain tight beyond CY27. Citi notes that suppliers are redirecting cleanroom space from NAND to DRAM, while limited total cleanroom capacity constrains NAND bit-supply growth. Micron expects its CY26 NAND supply growth to remain below the industry's; management also said it lacks visibility on when memory supply can catch up with rising demand, even if industry supply improves gradually in 2028. Citi's global memory analyst expects CY26 NAND ASPs to rise 186% year-on-year on robust enterprise-SSD demand and sees the market undersupplied through CY28. The report therefore expects suppliers to maintain pricing discipline, manage capital expenditure and supply cautiously, and use price increases and long-term agreements to improve profitability. Citi links the demand outlook to changing AI data-center architecture. Agentic and continuous AI inference increase data retrieval, inference iterations and processing density. As larger context windows make it uneconomic to retain all active data in GPU memory, frequent KV-cache eviction and recomputation raise latency and total cost of ownership. Citi argues that tiering context memory onto high-speed SSDs can retain and reuse KV cache and intermediate inference results, easing GPU-memory pressure, reducing redundant computing, improving token throughput and making latency more predictable. This supports enterprise SSD demand from hyperscale generative-AI training and inference, while AI-enabled smartphones, high-end PCs, consumer devices, automotive, industrial applications and robotics can broaden demand beyond data centers. For Sandisk, Citi raises estimates for improved near-term pricing and margins and sees the company as a beneficiary of the favorable NAND backdrop. The report cites Sandisk's BiCS8 qualifications as a competitive moat and expects a greater data-center mix to support margins over time. Citi forecasts CY27E EPS of US$222.15, up from US$217.70 previously, and values Sandisk at 11x revised CY27E EPS, up from its prior 9x multiple, to derive the US$2,500 target. Citi views the premium to Kioxia's median 8x P/E and the broader peer group's 6-8x P/E as justified by Sandisk's long-term agreements; it also notes estimated US$15-20 billion of JV invested capital or replacement cost not reflected in Sandisk's financial statements. The report reiterates Buy and opens an Upside 90-Day Short-Term View, expecting potentially favorable industry results and commentary, the August FMS conference, and Sandisk's August investor day to act as catalysts. Citi nevertheless flags that favorable conditions could reverse. Enterprise-share gains may take longer than expected, a weaker macro environment could reduce data-center spending, PC refresh activity or AI-PC traction, and aggressive Chinese competitors could intensify price competition. The report also cautions that underutilized industry capacity could turn quickly into oversupply, making price increases short-lived.

Analysis framework

Citi starts with Micron's reported results and guidance as a read-through for NAND conditions, then combines supply constraints, NAND ASP projections and AI data-center storage architecture to assess Sandisk's demand, pricing and margin outlook. It revises Sandisk earnings estimates and applies a forward P/E multiple to revised CY27E EPS, while comparing the resulting valuation with Kioxia and broader peers. The report also presents bull, base and bear cases around enterprise-bit growth and pricing.

Methodology notes

Asset mapping & comparison

Structured mapping from thesis to named assets (strengths, weaknesses, peers, risks).

• Sandisk Corp (SNDK.US)

  Primary covered company expected to benefit from tight NAND supply, stronger enterprise SSD demand and improved pricing.

  Strengths

  BiCS8 qualifications, enterprise SSD share-gain focus, growing data-center mix, established Kioxia production JV and long-term agreements.

  Weaknesses

  No DRAM exposure relative to many peers.

  Comparison

  Citi values Sandisk at 11x CY27E P/E versus Kioxia's median 8x and the broader peer group's 6-8x P/E.

  Risks

  Enterprise-share gains may take longer; macro weakness, price competition and a rapid return to NAND oversupply could impair the thesis.

• Kioxia (285A.T)

Impact & implications

Citi believes continued NAND undersupply and AI-led enterprise SSD demand can sustain higher pricing and improve Sandisk's earnings and margins. It sees Sandisk's enterprise focus, BiCS8 qualifications and growing data-center mix as differentiators, while the higher valuation multiple reflects its view of the company's long-term agreements and relative positioning.

Risks

• Sandisk's effort to increase Enterprise share could take longer than Citi expects.
• A weaker macro environment could reduce data-center spending, PC refresh activity or AI-PC traction that supports demand.
• Aggressive Chinese competitors could intensify pricing competition as they pursue market share.
• Underutilized industry capacity could rapidly shift the NAND market back to oversupply, making price increases short-lived.

What to watch

• Micron and other industry results and commentary, including the August FMS conference, for confirmation of NAND supply tightness and pricing.
• Sandisk's August investor day for updated expectations for 2HCY26 and CY27, its technology roadmap and capital-return outlook.
• Enterprise SSD demand from hyperscale generative-AI training and inference services.
• Progress in Sandisk's Enterprise share gains and data-center mix expansion.
