Key Highlights

  • SanDisk (NASDAQ:SNDK) rose 7.4% on October 28, 2026, and reports after the close on Thursday, October 29, with an earnings per share consensus of USD 45.22 on one calendar page.
  • That USD 45.22 figure looks extreme and comes from a single page, so it is flagged as unverified and should be checked before any use.
  • SK hynix reported quarterly revenue of 104.62 trillion won and operating profit of 83.33 trillion won, a 79.7% operating margin, with NAND prices up about 25% from the prior quarter.
  • The Philadelphia Semiconductor Index rose 1.75% on October 28, so SanDisk (NASDAQ:SNDK) reports into a chip rally that is heavily memory-led. Memory pricing is the central swing factor.

SanDisk Reports After a 7.4% Jump

SanDisk (NASDAQ:SNDK) gained 7.4% on October 28, 2026, a day after SK hynix posted a quarter of record profit, and is scheduled to report after the close on October 29. One earnings calendar page shows consensus earnings per share of USD 45.22. That number looks extreme, comes from a single page and could not be verified, so it should not be used without a check against company filings or other estimates. Results were not out when this was written, which makes this a preview. Until the release arrives, SanDisk's own numbers remain an open question. This makes the reaction to guidance and pricing language especially important. The consensus appears on the same calendar page that lists several other Thursday reporters.

Why Memory Prices Drive the Rally

SK hynix reported quarterly revenue of 104.62 trillion won and operating profit of 83.33 trillion won, a 79.7% operating margin from simple arithmetic on those two numbers. JPMorgan put the print 7% and 9% above consensus, with DRAM prices up almost 30% and NAND about 25% from the prior quarter. Because SanDisk (NASDAQ:SNDK) sells flash memory, higher NAND pricing is the key variable for its revenue and margins. The Philadelphia Semiconductor Index rose 1.75% on October 28 with 22 of 30 members higher, and the SK hynix ADR gained 13.3% to USD 164.70. That sequence matters because memory pricing sits at the centre of the chip rally.

Risks and What to Watch Next

A strong peer print raises expectations, so a merely good quarter could disappoint. Samsung Electronics fell 5.4% and the Kospi fell 2.2% on Thursday after its shareholder-return plan disappointed some investors, while Nvidia, AMD and Intel were indicated lower premarket. The 10-year Treasury yield closed above 5% on October 28, and Nasdaq-100 futures were down about 1.2% before 4:30 a.m. ET. Watch the NAND pricing commentary, guidance and inventory language in the SanDisk (NASDAQ:SNDK) release, and the 7:30 a.m. ET PCE inflation print earlier in the day. The bar for a reaction is higher after a rise of that size, so tone and guidance matter. Options-implied moves were not retrieved, so the size of the expected reaction is unknown.

Where Things Stand

SanDisk (NASDAQ:SNDK) is a memory-price test because SK hynix's results showed DRAM and NAND prices rising sharply, and SanDisk is the first flash-focused name to report afterwards. The evidence is incomplete: the USD 45.22 consensus is unverified and looks extreme, and no revenue or guidance estimates were retrieved. The next catalyst is the company release after the close, with SanDisk's NAND pricing commentary the key read.
