SanDisk Shares Extend Gains in Premarket Following 13.6% Surge

Key Facts

Reflecting growing optimism in the semiconductor sector, SanDisk shares rose an additional 4% in Friday's premarket trading. This extension of the rally follows a 13.6% surge in the previous session, triggered by management's ambitious financial targets unveiled during its Investor Day. According to reports, the company aims for revenue growth in the mid-to-high teens and sustained non-GAAP gross margins of approximately 80% through fiscal 2030.

The momentum has provided a significant lift to the broader memory group, with peers SK Hynix and Micron recording gains of 8% and 6% respectively. Per market data, Micron (MU) closed at $911.29 on August 12, 2026, while SanDisk (SNDK) finished at $1,344.29 on the same date prior to the current premarket move. Investor sentiment remains bolstered by projections that the enterprise data center flash market will reach 1.2 zettabytes by 2030, fueled by AI inference workloads.

Traders are now watching if the premarket strength translates into a sustained breakout at the Friday open, noting that SNDK hit an intraday high of $1,389.28 and MU reached $935.80 as of the August 12, 2026 close. With no major catalysts in the upcoming economic calendar, focus shifts to support levels near the previous session's lows of $1,308.53 for SNDK and $899.54 for MU. Markets also remain focused on the execution of the plan to return 100% of excess cash to shareholders.
