Sandisk Corp (SNDK)

Sandisk is a global semiconductor memory company with more than 30 years of experience in NAND flash technology. It became a standalone public company on February 21, 2025, when it separated from Western Digital Corporation (WDC), and its shares trade on the Nasdaq Global Select Market under the symbol "SNDK". The company is vertically integrated, owning chip-level design and IP, front-end and back-end manufacturing, and systems engineering and design. It develops flash storage solutions for AI workloads in datacenters, edge devices and consumer applications, and holds about 8,000 granted patents and about 3,000 pending patent applications worldwide.

Its products include solid-state drives (SSDs), embedded products, removable cards, universal serial bus drives, and wafers and components. They are organized into three end markets. Datacenter (formerly Cloud) covers high-performance enterprise SSDs and software for cloud service providers, private clouds and enterprise servers. Edge (formerly Client) covers SSDs for desktop and notebook PCs, gaming consoles and set-top boxes, plus embedded flash for phones, tablets, automotive, Internet of Things, industrial and connected-home uses. Consumer covers portable SSDs, removable cards and USB flash drives sold through retail and channel routes. Products are sold under the Sandisk brand, and some are sold for a limited transitional period under the Western Digital, WD and other brands licensed from WDC.

Customers range from students, gamers and home offices to large enterprises and public clouds. Datacenter sales go to cloud service providers and enterprise customers, Edge sales go to OEM and channel customers, and Consumer sales go through retail and other channels. The Unis Venture, which is 48% owned by Sandisk and 52% by Unis, markets and sells Sandisk products in China. The company is also moving toward long-term customer engagement frameworks and new business model agreements meant to improve revenue visibility and reduce exposure to industry cyclicality.

All of Sandisk's flash memory wafers come from its joint ventures with Kioxia: Flash Partners, Flash Alliance and Flash Forward, collectively Flash Ventures. They operate across eight manufacturing facilities in Yokkaichi and Kitakami, Japan. Sandisk holds 49.9% of each entity and is generally entitled to about 50% of the output, paying cost plus a small markup. It is also obligated to pay half of the fixed costs and to fund its share of capital investments. In January 2026 the parties extended the terms of Flash Partners and Flash Alliance to December 31, 2034, so all three ventures now co-terminate on that date. In connection with the extensions, Sandisk Technologies will pay Kioxia a total of $1.2 billion over 2026 through 2029. Controllers are mostly designed in-house and made by third-party foundries, or bought from third-party suppliers. Assembly and test take place at in-house facilities in Penang, Malaysia, at contract manufacturers, and at a facility run by SDSS, which is 20% owned by Sandisk and 80% by JCET. Sandisk competes with vertically integrated suppliers including Kioxia, Micron Technology, Samsung Electronics, SK Hynix and Yangtze Memory Technologies, as well as many smaller companies that assemble flash into products.
