SanDisk Jumps 5.3% as an Analyst Upgrade Collides With a Shrinking NAND Share

SanDisk shares drew a bid on Tuesday, climbing 5.3% as a broader rebound in AI-linked equities and softer crude prices lifted sentiment across the US market, according to reporting from the Associated Press. The advance puts the memory maker back in favor alongside other artificial-intelligence names that had sold off the previous week.

Yet the rally arrives with a caveat that has little to do with the tape. Analyst Gytis Zizys upgraded SanDisk to "Buy," arguing the market's recent punishment of the stock was overdone. Wells Fargo, by contrast, stayed neutral and trimmed its price target to $1,300.

A Question of Share, Not Just Margins

The more consequential signal sits in the competitive data. Counterpoint Research pegs SanDisk's slice of global NAND revenue at 11% in the second quarter of 2026, down from 13% in the prior quarter. Rival YMTC, meanwhile, climbed to 14% from 12% in the fourth quarter of 2025 — even as worldwide NAND revenue swelled 70% quarter over quarter.

That divergence undercuts any explanation that pins SanDisk's troubles solely on the broader AI trading mood. A company losing relative ground in an expanding market has a harder case to make to investors, and a stabilization of share would be worth more than any single strong quarter. Durable re-rating, in Zizys's framing, requires both fat profits and a firmer competitive foothold.

The Earnings Case Is Genuinely Strong

Against that backdrop, the operating numbers remain striking. In the first quarter of fiscal 2027, SanDisk posted revenue of $11.03 billion — a 378% surge year over year — with an adjusted gross margin of 85.1%. GAAP diluted earnings per share came in at $52.60.

The data-center unit did much of the heavy lifting, generating $4.8 billion in revenue and growing 61% sequentially. Consumer revenue, by contrast, contracted 29%. That lopsided mix raises the stakes on data-center demand, particularly as media reports flag investor anxiety over permitting, power costs and local opposition to new projects — hurdles that could delay chip orders if infrastructure buildouts stall.

Guidance Is Where the Optimism Gets Tested

Management's outlook for the second quarter of fiscal 2027 calls for revenue of $12.2 billion to $12.6 billion, with adjusted gross margin of 84.5% to 85.5%. On a non-GAAP basis, diluted EPS is projected at $55.00 to $57.00.

Those targets set a demanding bar. The bullish read is that SanDisk expects to keep growing while holding margins near record levels; the closer actual results land to that forecast, the stronger the argument that the market has been too harsh. Zizys leans on hefty free cash flow and a debt-free balance sheet to support his call.

The Split Runs in Parallel

Separately, the mechanics of the announced 8-for-1 forward stock split are now in motion. Tuesday marks the record date, with the additional shares to be distributed after the close on November 19 and split-adjusted trading expected from November 20. The split reshapes the trading calendar but leaves shareholder value untouched — the operating numbers, not the share count, remain the real yardstick.

What matters for investors is whether SanDisk can carry its revenue momentum into the next reporting period and convert guidance into delivered results. A friendlier market helps, but only for as long as the growth story holds up.
