SanDisk Corp (NASDAQ: SNDK) is a flash memory storage company that designs, manufactures, and sells NAND flash storage products. It generates revenue through transactional sales of flash-based storage devices across consumer, commercial, and data center end markets. SanDisk was spun off from Western Digital Corporation (WDC), with the separation completing on February 21, 2025, at which point SanDisk entered into a Term Loan B facility of $2.0 billion and a $1.5 billion revolving credit facility, using approximately $1.5 billion of borrowing proceeds to make a net distribution payment to WDC. Flash memory manufacturing is conducted through Flash Ventures, a joint venture with Kioxia comprising three entities: Flash Partners Ltd., Flash Alliance Ltd. (both set to expire December 31, 2029), and Flash Forward Ltd. (set to expire December 31, 2034). As of June 27, 2025, no amounts had been drawn on the revolving credit facility. The company carries meaningful debt from its term loan and operates in a capital-intensive manufacturing environment, with FY2025 charges of $75 million for unabsorbed manufacturing overhead due to reduced utilization.
