Sandisk Stock Split November 19: 8-for-1 Dates, Share Math and What Changes

Sandisk (NASDAQ: SNDK) is splitting its stock 8-for-1. Holders get seven extra shares for each share after the close on Thursday, November 19, 2026, and the stock trades on a split-adjusted basis from Friday, November 20. Here are the exact dates, what happens to your shares, price and earnings per share, and how this split compares with Nvidia, Apple and other big splits.

Sandisk stock split November 19: what the 8-for-1 split changes

Sandisk announced the split with its fiscal first-quarter results on October 29, 2026. It is an eight-for-one forward split: stockholders of record at the close of business on November 9, 2026 receive seven additional shares for every share they hold, issued after the market close on Thursday, November 19, 2026. Trading on a split-adjusted basis is expected to start at the market open on Friday, November 20, 2026, under the same ticker, SNDK.

Nothing about the value of the company changes. Every holder ends up with eight times as many shares, each priced at about one eighth of the pre-split price, so a position worth $10,000 on November 19 is still worth about $10,000 on November 20 before normal market moves. The company says market capitalization and each holder's ownership percentage are not affected.

Sandisk says the goal is to make the stock more accessible, including for employees buying through its employee stock purchase plan. The split is carried out by amending the certificate of incorporation, which raises authorized common shares from 450 million to 3.6 billion, exactly eight times the old limit.

Before vs after the split: shares, price and EPS per share

Sandisk stock split math: what happens to your shares and options

Multiply your share count by eight and divide your price per share by eight. 1 share becomes 8, 25 shares become 200, 100 shares become 800. Your total cost basis does not change: if you paid $90,000 for 100 shares, you now own 800 shares with a cost basis of $112.50 each. A forward split is not a taxable event in the United States, and brokers adjust the basis automatically.

Fractional shares at brokers that support them are multiplied the same way, so 0.5 share becomes 4 shares. Limit and stop orders left open across the split are often cancelled or adjusted by the broker; check your open orders on November 20 rather than assuming they carried over at the right price.

Listed options are adjusted by the Options Clearing Corporation. For whole-number splits the usual method is to multiply the number of contracts by the split ratio and divide the strike price by it, so one $1,000 call would become eight $125 calls. Read the clearing house memo for SNDK before trading options around November 20. Per-share figures such as earnings per share and the share count in future reports will be restated on a split-adjusted basis.

Big stock splits compared: Sandisk vs Nvidia, Apple and others

Should you buy Sandisk stock before the November 19 split?

A split alone does not make the stock cheaper. At a price of about $117 after the split, you are buying exactly the same slice of the company that cost about $937 before it. Studies of past splits show some short-term buying interest around the announcement, but the record date has already passed and the split has been public since October 29, so that effect is likely already in the price.

If you buy shares before November 20, you still end up with eight shares for each share you buy. For large forward splits, exchanges attach the right to the extra shares to shares traded between the record date and the distribution date, so buyers through November 19 are covered and the ex-split date falls on November 20. Confirm with your broker if you trade on November 19 itself.

The real question is the business. Sandisk reported fiscal Q1 2027 revenue of about $11.0 billion, up 23% from the prior quarter, with a gross margin of about 85%, and guided next-quarter revenue to $12.2 billion to $12.6 billion. Yet the stock closed November 12 around 60% below its June high as the Nasdaq sold off and investors questioned how long memory pricing can stay this strong. Memory is a cyclical business, so judge SNDK on where the pricing cycle goes, not on the split. This page is research, not investment advice.
