Since its spinoff from Western Digital, SanDisk’s AI-driven rally has seen its stock rise over 3,900% in twelve months, exceeding $1,550. Driven by demand for NAND technology in AI infrastructure, the company reported fiscal Q4 2026 revenue of $8.965 billion—a 371.6% year-over-year increase—with a net income of $6.9 billion. Total fiscal 2026 revenue reached $20.25 billion, a 175% increase.

A significant structural shift has occurred in SanDisk’s revenue streams, with datacenter sales reaching $2.98 billion in fiscal Q4 2026. This represents approximately one-third of total quarterly revenue, a massive increase from $213 million in the same quarter the previous year. To stabilize revenue against cyclical memory pricing, the company has implemented a ‘New Business Model’ involving multiyear supply agreements, currently holding ten such agreements across eight customers.

Technological development has reached a milestone with the tape-out of the first High Bandwidth Flash (HBF) design. To meet global demand, SanDisk and Kioxia Corporation plan to invest over $31 billion in Japan through 2032 to expand the Yokkaichi and Kitakami facilities, contingent upon government support. Kioxia CEO Hiroo Ota stated the investment underscores a commitment to an ‘AI-driven society’ to maintain competitiveness against rivals like Samsung and SK Hynix.

Despite growth, the company has implemented layoffs at its Israeli development centers. While institutional interest remains high, the stock remains subject to volatility. Notably, insider Bernard Shek sold 600 shares for approximately $915,360 under a pre-arranged Rule 10b5-1 trading plan following the recent earnings surge.
