SanDisk Shareholders Face a Split Deadline as Jane Street Discloses 3.7% Stake
Published on 11/09/2026 at 15:41 | Editorial boerse-global.de
SanDisk stock closed Friday at €750.00, up 4.2%, as a broad recovery in memory names lifted the sector. The rebound followed reports that concerns about data-center construction were easing after Texas governor-designate Gina Hinojosa said projects already approved could be completed. The advance placed the shares in a sector-wide countermove after an AI-linked selloff had weighed on memory stocks.
Friday also brought a regulatory filing that put Jane Street's economic interest in SanDisk at 5,478,633 shares, or 3.7% of the company. The disclosure is a mandatory notification, and its weight should be judged against the operating story rather than in isolation. That story rests on the guidance SanDisk issued on October 29 alongside its fiscal first-quarter 2027 results.
A Split With a Fixed Calendar
Today marks the record date for the eight-for-one stock split SanDisk announced on October 29. Shareholders registered as owners on that date are set to receive seven additional shares for each one they hold. The distribution of the new shares is scheduled for after the close on November 19, with split-adjusted trading expected to begin on November 20.
The split changes the share count, not the value of anyone's holding. It does, however, matter for one detail in the guidance: the earnings-per-share forecast is stated on the pre-split share count.
Should investors sell immediately? Or is it worth buying SANDISK?
Revenue Growth Sets the Bar
For the first quarter of fiscal 2027, SanDisk reported revenue of $11.03 billion, up 23% from the prior quarter and 378% from a year earlier. GAAP net income came in at $8.101 billion, while non-GAAP diluted earnings per share reached $49.51. The data-center segment contributed $4.8 billion in revenue, a 61% increase over the immediately preceding quarter.
Management guided second-quarter fiscal 2027 revenue to a range of $12.2 billion to $12.6 billion, implying further growth from the quarter just reported. Adjusted diluted earnings per share for the same period are projected at $55.00 to $57.00, on a pre-split basis.
Insider Sale Followed a Preset Plan
Among the disclosures surrounding the stock was a reported insider transaction: Bernard Shek, SanDisk's Chief Legal Officer and Secretary, sold a total of 600 shares on November 2. The sale was executed under a trading plan adopted on March 4 in accordance with Rule 10b5-1. Because the timing was set in advance, the transaction carries limited signal about management's view of the business.
SANDISK at a turning point? This analysis reveals what investors need to know now.
What carries more weight is whether SanDisk delivers on the expansion it has promised. The reported figures give the bullish case substance; their continuation depends on the company hitting its next announced growth step. For investors, that condition matters more than any single shareholder filing — and more than the mechanics of the split itself.
