[OKX Announcement Regarding SNDK Stock Split and Adjustments to Related Spot, Perpetual, and Xperp Products] This announcement is a general update. Please refer to the app for the app's display regarding whether the relevant products are applicable to your region. Sandisk Corporation (NASDAQ: SNDK) has announced an 8-for-1 stock split, meaning each share will be split into 8 shares. To ensure that the prices of the relevant products are consistent with the underlying assets after the stock split, OKX will adjust the relevant xSNDK spot, SNDK perpetual, and Xperp products starting **November 20, 2026, 09:00 (UTC+8)**. The stock split itself does not generate additional investment income. The number of shares or positions held will increase to 8 times the original amount, and the corresponding unit price will be adjusted proportionally to 1/8 of the original price. The actual adjustment result is subject to applicable precision and settlement rules. I. Basic Information on the Stock Split Project Details Underlying Stock: Sandisk Corporation (NASDAQ: SNDK) Stock Split Ratio: 1 for 8, with 7 additional shares for every 1 share held Stock Split Implementation Date: After the close of the US stock market on November 19, 2026 OKX Adjustment Start Date: 09:00 (UTC+8) on November 20, 2026 Please refer to the official Sandisk announcement for details of the stock split. II. Affected Products and Trading Arrangements Product Line Affected Trading Pairs/Contracts (Product ID) Start Time of Adjustment Spot XSNDK-USDT November 20, 2026, 09:00 (UTC+8) Spot XSNDK-USDC November 20, 2026, 09:00 (UTC+8) Perpetual Contract SNDK-USDT-SWAP November 20, 2026, 09:00 (UTC+8) Xperp SNDK-USD_UM_XPERP-310627 November 20, 2026, 09:00 (UTC+8) During the official adjustment period, order placement, modification, cancellation, and order matching will be suspended for the relevant products. Related forced liquidation will also be suspended. Deposits, withdrawals, and transfers of affected assets may also be suspended simultaneously; please refer to platform announcements for details. After adjustments and verification, the relevant products will enter a Post-only (Maker-only) phase for at least 10 minutes. During this phase, only Post-only limit orders can be submitted, and existing Post-only orders can be modified or canceled; market orders, IOC, FOK, regular limit orders, and new stop-loss/take-profit orders are not supported. After the Post-only phase ends, the relevant products will resume normal trading without waiting for the US stock market to open. Entering the Post-only phase does not guarantee the resumption of normal matching, and the 10-minute period does not necessarily mean normal trading has resumed; the specific resumption time depends on the actual product status and platform notifications. Asset transfers, normal trading, index components, and price limits may resume at different times. III. Spot Adjustment Rules xSNDK spot holdings will be adjusted according to the stock split ratio and issuer terms: Item Adjustment Method Platform Holding Shares Original Shares × 8 The underlying asset price per share will be adjusted to 1/8 of the original price according to the stock split ratio. Actual Adjustment Result Subject to applicable precision rules and account records For example, if you held 10 shares before the adjustment, you will theoretically hold 80 shares after the adjustment. The increase in shares is accompanied by a proportional decrease in the unit price and does not represent an increase in the holding value. IV. Perpetual Contracts and Xperp Adjustment Rules Perpetual contracts and Xperp use the same stock split processing method: The system first settles the original position at the pre-adjustment mark price, converting unrealized profits and losses into realized profits and losses, and then establishes a new position at the adjusted mark price. Position Quantity: Original position quantity × 8, applicable existing quantity precision rules. Index Price/Mark Price Adjustment Reference Value: Calculated by ÷ 8 of the snapshot value before adjustment. New Position Opening Average Price: Adjusted mark price. Original Position Unrealized Profit/Loss: Settled as realized profit/loss. New Position Unrealized Profit/Loss: 0 at the settlement reference point for re-establishing the position, subsequently changing with market conditions. System Adjustment Fee: No transaction fee is charged for closing or reopening positions this time. Contract Face Value, Minimum Price Fluctuation Unit, and Quantity Step: This stock split itself does not change the above parameters. Funding Fee Settlement Frequency: This stock split itself does not change the normal settlement frequency. The new position opening average price is the adjusted mark price, not simply the original opening average price divided by 8. The original position's profit/loss has already been settled and does not disappear due to the new position's unrealized profit/loss being zeroed out. The adjusted mark price will change according to the normal pricing mechanism and will not be fixed at the reference value at the time of the stock split. Related precision discrepancies are handled through company action settlement and necessary balance adjustments; the settlement currency is subject to the corresponding product rules. V. Order Processing Rules Order Type/Status Processing Method Eligible Limit and Post-only Orders: Order Price ÷ 8, Unfilled Quantity × 8 Completely Unfilled Orders: Retain original order ID, adjust price and quantity Partially Filled Orders: Only adjust the unfilled portion and re-place the order, generating a new order ID Orders Not Meeting Precision or Other Transaction Validation Requirements: Canceled, not retained or re-placed Untriggered Take-Profit/Stop-Loss Orders: Canceled and will not automatically resume Running Grid Strategies: Paused during adjustment; manual resumption is required after normal trading resumes Other Running Strategies or Bots: May be paused; please check their running status after trading resumes Adjusted buy order prices are aligned downwards and sell order prices are aligned upwards to the minimum price fluctuation unit; unfilled quantities are aligned downwards to the quantity step. If the adjusted quantity is zero or lower than the minimum order quantity, the order will be canceled. Completed historical transaction records will not be rewritten due to this stock split. VI.
