New York, January 4, 2026, 17:11 ET — Market closed
Sandisk Corp shares closed up nearly 16% at $275.24 on Friday after the flash-memory maker said it appointed First Solar CFO Alexander R. Bradley to its board. “Alex brings exceptional operational finance expertise and strategic insights to Sandisk’s board,” Chief Executive David Goeckeler said. The stock traded between $242 and $278.78 in the session, with volume topping 11 million shares. 1
The rally keeps Sandisk near a year-end peak after a breakneck 2025 run following its mid-February spin-off from Western Digital, when the shares began trading at $36. Investors have tied the story to enterprise solid-state drives — storage devices that use flash memory rather than spinning disks — which are in demand for data centers handling data-heavy AI workloads. 2
The bid was not isolated. Micron Technology ended Friday up about 10.5% and Western Digital rose roughly 9%, extending a trade that has rewarded storage and memory names with exposure to data-center spending.
A Form 3 filed with the U.S. Securities and Exchange Commission on Jan. 2 showed Bradley reported no beneficial ownership of Sandisk securities as of Dec. 30.
The speed of Friday’s move also highlighted how quickly sentiment can swing in a high-momentum stock, where sharp gaps can invite both trend-following buyers and fast profit-takers.
For Sandisk, the next debate is less about the boardroom and more about the NAND flash cycle. NAND is the core flash-memory technology used in most SSDs, and its prices tend to rise and fall as supply catches up with demand.
Technically, traders will watch whether Sandisk can push through the $280 area after stalling just below that mark. A slide back toward the mid-$230s would put the latest breakout under pressure and test how much conviction sits behind the AI-storage theme.
But flash-memory trades can turn quickly if pricing softens or customers delay orders, and the macro calendar can jolt rate expectations that feed into tech valuations. Markets are heading into the Jan. 9 U.S. jobs report and the Federal Reserve’s Jan. 27-28 policy meeting, both potential catalysts for volatility. 3
With U.S. markets reopening Monday, investors will be looking for follow-through after the stock’s sharp gap higher — and for any sign that the move was more than a one-day sprint on a light news docket.
Sandisk said it will report fiscal second-quarter results on Jan. 29 and hold its earnings call at 4:30 p.m. ET. Investors will focus on demand signals for enterprise SSDs, pricing trends and any change in guidance for the rest of fiscal 2026. 4
