Update: September 8th, 2023

On August 28th, 2023, Sorrento Therapeutics (SRNE) filed a motion to extend the restriction of Scilex Holding (SCLX) stock until December 1, 2023.

Sorrento Therapeutics plans to complete a stock dividend on January 19th, 2023. All holders of SRNE will receive 0.1410127 share{s} of Scilex Holding (SCLX) for each SRNE share held at the close of trading on January 5th, 2023

Due to the restriction, you will be unable to sell the SCLX shares received until the restriction is removed. Restricted SCLX shares will not be visible in Cash App but you may review your holdings on your monthly statements.

You will find the restricted shares under Symbol:808CNT018 on your monthly statement.

When the restriction ends, shares of 808CNT018 will be removed from your account and replaced with the same number of regular,unrestricted SCLX shares. The unrestricted SCLX shares will be available in app once they are received and you will be able to sell those shares at that time.

To learn more about restricted shares, please see this article from the U.S. Securities and Exchange Commission [here] (https://www.sec.gov/reportspubs/investor-publications/investorpubsrule144)

This will affect all SRNE shareholders. Due to this stock dividend, scheduled orders for SRNE will not be accepted between market close on January 18th, 2023 and market open on January 19th, 2023

How will this impact my holdings?

Your total number of SRNE shares will remain unchanged and you will receive 0.1410127 share{s} of SCLX for each SRNE share held.

This may lower the price of each SRNE share as a portion of SRNE’s value will transfer to the new company’s stock, SCLX.

Immediately after the stock dividend is issued, your combined positions in SRNE and SCLX will have a similar value to your original SRNE position.

For example: if you have 5 shares of SRNE stock, during this stock dividend, Sorrento Therapeutics will grant you 0.7050635 SCLX shares.

You will have 5 shares of SRNE and 0.7050635 shares of SCLX, which combined will have a similar value to your original 5 SRNE shares.

Note: Market fluctuations unrelated to the stock dividend may impact the value of these two positions during this time period.

How can I calculate the number of shares I will own?

To calculate the number of Scilex Holding shares that you will own after the stock dividend, follow the math below

Sorrento Therapeutics shares previously owned x 0.1410127 = New amount of Scilex Holding shares you will receive.

For example:

• Before the spin-off you owned 5 shares of Sorrento Therapeutics.

• Use the equation above (5 previously owned shares x 0.1410127)

• You now own 0.7050635 shares of Scilex Holding and continue to own your original position of 5 shares of Sorrento Therapeutics.
