what happened
Sandisk shares were down 5.7% at $1,491.35 by 12:41 p.m. ET on Monday. GuruFocus, citing an October 12 report from Investing.com, said Goldman Sachs sees an opportunity in high-bandwidth flash, or HBF, but Sandisk must still show that the business can generate adequate profits.
On August 3, Sandisk and SK hynix published an Open Compute Project technical specification. Google and Tenstorrent helped with validation and standardization. The framework is designed to place more memory close to computing cores and enables HBF to operate alongside high-bandwidth memory.
According to Investing.com, Goldman’s optimistic scenario sees HBF using 9% of global NAND wafer capacity but accounting for only 4% of bit shipments by late 2028. Sandisk’s GF Score is 45/100, reflecting stronger growth and financial-strength readings than profitability results.
why it matters
Greater wafer use could tighten supply and support pricing, while also making returns harder to achieve. Sandisk still needs customer approvals, dependable manufacturing yields and prices that justify the capacity consumed.
