Sandisk is splitting its stock 8 for 1, turning a share that closed near $1,151 on Friday into eight shares worth about $144 each. Here are the key dates, what changes in your account, why the stock just dropped 13% anyway, and what to expect heading into November 20.
Prices as of the October 30, 2026 close. Dates from Sandisk’s October 29 SEC filing. Sources listed at the bottom of this post.
What Sandisk announced
On Thursday, October 29, Sandisk reported its fiscal first quarter results and paired them with news shareholders had been hoping for. The board approved an eight for one forward stock split. Every share you own will become eight shares, and the price of each share will be divided by eight.
Sandisk said it’s doing the split to make the stock more accessible, including to its own employees who buy shares through the company’s stock purchase plan. That makes sense. After a run of more than 500% over the past year, a single SNDK share has been priced well above $1,000, which is a lot for a new investor or an employee buying a few shares each paycheck.
The split does not change what Sandisk is worth. The company’s market value and your ownership percentage stay exactly the same. You’ll simply hold more shares at a lower price each.
Key dates for the SNDK stock split
- October 29, 2026: Split announced alongside fiscal Q1 2027 earnings.
- November 9, 2026: Record date. Shareholders of record at the close of business will receive seven additional shares for each share held.
- November 19, 2026: The new shares are issued after the market closes.
- November 20, 2026: SNDK begins trading on a split adjusted basis at the market open, under the same ticker.
Buying after November 9 doesn’t mean you miss out. For forward splits like this, Nasdaq typically uses a process called due bills, so shares bought before the split takes effect still carry the right to the extra shares. Your broker handles it automatically. If you want to be sure, check with your broker.
What happens to your shares
You don’t need to do anything. On the morning of November 20, your account will show eight times as many SNDK shares, each priced at roughly one eighth of the previous close.
Same money, more shares
Example using Friday’s October 30 close. The real post split price will depend on where SNDK trades on November 19.
Your cost basis is adjusted the same way. If you bought one share at $800, you’ll now own eight shares with a cost basis of $100 each. The split itself is not a taxable event.
Sandisk’s numbers before and after the split
Every per share number gets divided by eight. Here’s a cheat sheet so the new figures don’t catch you off guard when they show up on your screen.
| Metric | Before split | After split |
|---|---|---|
| Share price (Oct 30 close) | $1,150.89 | ~$143.86 |
| 52 week high | $2,354.39 | ~$294.30 |
| Q1 adjusted EPS | $49.51 | ~$6.19 |
| Q2 adjusted EPS guidance | $55 to $57 | ~$6.88 to $7.13 |
| JPMorgan price target | $2,250 | $281.25 |
| Morningstar fair value | $870 | ~$108.75 |
| Authorized shares | 450 million | 3.6 billion |
Notice the gap between those last two analyst numbers. JPMorgan sees major upside while Morningstar thinks the stock is already well above fair value. That disagreement tells you how much uncertainty surrounds this stock right now.
Why SNDK fell 13% despite a blowout quarter
On paper, this was a monster quarter. Revenue hit about $11.03 billion, up 23% from the prior quarter and up 378% from a year earlier. Adjusted earnings of $49.51 per share beat estimates of around $47. Gross margin reached 85.1%, a level almost unheard of for a hardware company. Sandisk also bought back $5 billion of its own stock during the quarter and guided to even higher revenue of $12.2 billion to $12.6 billion next quarter.
Wall Street sold it anyway. SNDK closed Friday at $1,150.89, down 13.5% on the day and roughly half its June record. A few things drove the selling:
- NAND price gains are slowing. Sandisk’s manufacturing partner Kioxia reported that its flash memory prices rose in the mid 20% range last quarter, down sharply from about 70% the quarter before. Investors worry the pricing boom is peaking.
- Less growth from pricing. Price increases drove about 40% of Sandisk’s quarterly growth, down from about two thirds in the prior quarter, and the CFO guided to only modest price increases from here.
- Consumer weakness. Consumer revenue fell 29% from the prior quarter to $397 million. CFO Luis Visoso said that drop came “as the market adjusts to higher pricing.”
- A rough day for tech. Weak guidance from Intel and a broader chip selloff added pressure across memory stocks.
Not everyone turned negative. Bernstein argued that “pricing and buybacks more than offset cost headwinds,” and Bloomberg Intelligence expects NAND supply to stay tight through at least the first half of 2028 as AI data centers keep buying storage.
What to expect before and after the split
Between now and November 20
Stocks sometimes drift higher into a split date as retail interest builds, but that’s far from guaranteed, and SNDK is coming off a sharp drop. The bigger drivers over the next three weeks are likely to be NAND pricing headlines, competitor earnings and how the broader chip sector trades. Expect volatility either way.
On split day
The price will open around one eighth of the November 19 close. Trading volume often rises around a split as the lower price draws in new buyers, and moves can look exaggerated on charts and apps until data providers fully adjust historical prices.
Over the next year
History offers mild encouragement. A Motley Fool review of eight recent split announcements found that five of the stocks were higher a year later, though the size of the gains varied widely. A split can bring more attention, but over time SNDK will trade on NAND prices, data center demand and whether those 85% margins hold up.
Bull case: the AI storage story wins
Supply stays tight, data center demand keeps growing, and buybacks continue. The lower share price brings in new retail buyers and SNDK recovers toward analyst targets like JPMorgan’s split adjusted $281.
Base case: choppy but range bound
Strong earnings support the stock, but slowing price increases cap enthusiasm. SNDK trades in a wide range after the split while investors wait to see if margins have peaked.
Bear case: the memory cycle turns
NAND prices flatten or fall as new supply comes online and consumer demand weakens further. Margins compress and the stock drifts toward more cautious valuations like Morningstar’s split adjusted $109.
What options traders should know
A forward split changes your options contracts too. For an 8 for 1 split, existing contracts are typically adjusted so you hold eight times as many contracts, each with a strike price divided by eight. A single $1,200 call becomes eight $150 calls, and the total value of your position stays the same.
- Watch for the Options Clearing Corporation memo on SNDK, which will confirm exactly how contracts are adjusted.
- After the split, one contract will control 100 shares worth about $14,400 instead of about $115,000 at today’s prices. That makes buying and selling options far more affordable for smaller accounts.
- Implied volatility has been elevated after the earnings drop. Remember that cheaper contracts in dollar terms aren’t necessarily cheaper in risk terms.
Our take: what this split means for SNDK
The split itself is cosmetic. It won’t make Sandisk a better or worse investment, but it will make the stock easier to buy, easier to give to employees, and much easier to trade options on. That alone can bring more volume and attention.
The real story is the memory cycle. Sandisk just posted one of the most profitable quarters any chip company has ever reported, and the stock still fell 13% because investors are trying to figure out when NAND pricing peaks. Memory has always been a boom and bust business, and the slowdown in price gains is the kind of early signal that makes traders nervous.
Our read: expect a volatile run into November 20, not a guaranteed split rally. Over the longer term, watch NAND contract prices and gross margin more closely than the share price. If margins hold above 80% while data center demand keeps climbing, the bulls have a strong case. If they start slipping, the split won’t save the stock.
What to watch next
- November 9 record date and November 20 split adjusted open.
- NAND contract pricing updates from Sandisk, Kioxia, Samsung and Micron.
- The OCC adjustment memo for SNDK options.
- Progress on Sandisk’s remaining $10.5 billion buyback authorization.
- Fiscal Q2 results, where Sandisk guided to $12.2 billion to $12.6 billion in revenue.
Sandisk stock split FAQ
When does the Sandisk stock split take effect?
The new shares are issued after the market closes on November 19, 2026, and SNDK starts trading on a split adjusted basis at the open on Friday, November 20, 2026. Shareholders of record on November 9 receive the new shares.
Do I need to do anything to get my split shares?
No. Your broker will automatically add seven additional shares for every share you own. Your cost basis per share will also be adjusted automatically.
Does the split make Sandisk stock cheaper?
Only per share. Each share will cost about one eighth as much, but you’ll get eight times as many. The company’s total value and your ownership stake don’t change.
What happens to my SNDK options?
Contracts are typically adjusted so you hold eight times as many contracts with strikes divided by eight. Check the Options Clearing Corporation memo for the final details.
Do stocks go up after a split?
Sometimes, but not always. Studies show split stocks have often outperformed in the year after an announcement, largely because strong companies tend to split. The split itself doesn’t create value.
