SanDisk Shares Retreat as Lock-Up Period Concludes

SanDisk shares fell over 8% as a lock-up period ended, triggering profit-taking. Despite the sell-off, the company posted strong Q2 revenue growth of 61% and raised future guidance.

After reaching a record high, SanDisk's stock experienced a sharp reversal, shedding over 8% in a matter of days. This dramatic shift highlights how quickly market sentiment can change, driven not by operational issues but by a specific corporate event: the expiration of a lock-up agreement.

Strong Fundamentals Overshadowed by Structural Selling

The sell-off was triggered last Friday when approximately 2.03 million previously restricted shares became freely tradable. These securities had been held under a 30-day lock-up by company directors, senior executives, and its former parent corporation, Western Digital. Trading volume surged to 23.5 million shares on the day, significantly above the recent daily average of around 19.6 million. For early investors, the unlocking presented a timely opportunity to realize profits following an impressive rally of roughly 180% since the start of the year.

The company's underlying business performance, however, tells a much more robust story.

Impressive Financial Performance and Upward Guidance

SanDisk reported revenue of $3.03 billion for the second quarter of fiscal 2026, representing a substantial 61% year-over-year increase. Even more notable is the margin expansion. The non-GAAP gross margin climbed to 51.1%, a significant jump from 32.5% in the same quarter last year and 29.9% in the preceding quarter. This improvement is powered by the adoption of its 8th-generation 3D-NAND technology (BiCS8) and a growing sales mix of higher-margin enterprise solid-state drives (SSDs).

Looking ahead, management has provided optimistic guidance for the current third quarter. The company anticipates revenue in the range of $4.4 to $4.8 billion, with non-GAAP gross margins projected between 65% and 67%, signaling another major leap forward.

Raised Price Target and Stock Split Speculation

In light of these strong fundamentals, analysts at Citi have reaffirmed their Buy rating on SanDisk shares. They have also raised their price target from $750 to $875. The firm's analysts base their positive outlook on expectations of a sustained global NAND shortage lasting at least until 2027, further bolstered by SanDisk's long-term supply agreements with major cloud service providers.

Concurrently, market speculation is growing regarding a potential stock split. With the company's market capitalization now exceeding $110 billion, the high nominal share price is seen as a potential barrier for some retail investors. While the company's management has not yet announced a concrete timeline, reports indicate it is reviewing its capital structure options.
