Sandisk (SNDK) Stock Analysis & Forecast
Nov 4 close
$1,037.40−89.12 (−7.9%)
Gekko Brief
AI summaryNov 4 closeSandisk shares fell sharply this week after Democrats took control of both the Senate and House in the midterm elections, fueling concerns about increased AI regulation in 2027 and weighing on memory and storage peers including Micron, SK Hynix and Western Digital. The stock also drew attention around its Q1 FY2027 results, which showed revenue of $11 billion, non-GAAP gross margin of 85.1% and non-GAAP EPS of $49.51 against a $46.67 estimate, with data-center revenue up 61% sequentially to $4.8 billion while consumer sales fell 29%. One commentator upgraded the stock to Buy on the pullback, and coverage also noted an upcoming stock split and a market value decline from a record $347 billion in June to about $147 billion.
Sandisk closed at $1,037.40, down 7.9% on the day, extending a decline that leaves it down 37.5% over the past month and 17.6% over three months, though still up 401.1% over the past year. The close sits between the 50-day average of $1,531.29 and the 200-day average of $1,268.98, a mixed trend picture. The GekkoIndex reads 70, placing the stock in the Buying zone, and the price sits 34.5% below the Gekko Fair Value of $1,583.15.
The next earnings report is set for 4 February 2027, 92 days away and outside a typical 20-trading-day hold; the prior report on 29 October 2026 brought an 18.1% reaction despite the EPS beat. Over the last 90 days, Congress recorded 1 buy and 0 sales, while the last 30 days show 5 unusual options signals, with call premium of $298.0 million against put premium of $55.5 million. Among 18 covering firms, 15 rate it Buy, 3 Hold, and the consensus target stands at $2,029.04, a 95.6% consensus upside figure worth noting.

About Sandisk
Sandisk works in the design, manufacture, and supply of storage solutions and devices built on advanced NAND flash technology. Its product range includes solid-state drives, embedded memory solutions, removable memory cards, and universal serial bus devices, along with the underlying wafers and components used to build them. Together these offerings cover storage needs from raw memory components through to finished, ready-to-use devices.
The company operates across this full range of storage formats, combining component-level manufacturing with consumer and embedded product lines rather than focusing on a single product type. This spread allows it to supply storage technology at different points, from wafers and components up through complete memory cards, drives, and USB devices.
Sandisk was founded on June 1, 1988. Its principal executive offices are located in Milpitas, California. The company's shares are listed on the NASDAQ under the ticker SNDK.

- What they said
- SanDisk reported Q1 FY2027 revenue of $11 billion with non-GAAP gross margin of 85.1% and non-GAAP EPS of $49.51, exceeding guidance. The company generated $5.7 billion in adjusted free cash flow and returned $5 billion to shareholders via buybacks. Key technology milestones include BiCS8/9/10 NAND generations and High Bandwidth Flash tape-out, with AI-driven NAND demand cited as a secular growth tailwind extending customer visibility beyond FY2030.
