NOTICE OF POSTPONEMENT OF 2023 ANNUAL MEETING OF STOCKHOLDERS

Dear Stockholders of Scilex Holding Company:

Notice is hereby given that the 2023 Annual Meeting of Stockholders (the “Annual Meeting”) of Scilex Holding Company, a Delaware corporation (the “Company” or “Scilex”), which was originally scheduled for Thursday, April 6, 2023 at 9:00 a.m. Pacific Time, has been postponed and rescheduled for Monday, April 17, 2023 at 9:00 a.m. Pacific Time via live audio webcast on the Internet at www.virtualshareholdermeeting.com/SCLX2023.

As the Company previously announced, there are more than 44 million shares of the Company’s common stock, par value $0.0001 per share (“Common Stock”), that have not yet been reported by brokers, banks and other nominees (collectively, “brokerage firms”) to Broadridge Financial Solutions, Inc. (“Broadridge”), an independent third party that collects and tabulates stockholder votes for the upcoming Annual Meeting. On March 9, 2023, Broadridge distributed the proxy materials for the Annual Meeting (the “Proxy Materials”) to all Scilex stockholders of record as of March 6, 2023, the record date for the Annual Meeting (the “Record Date”).

On April 4, 2023, Sorrento Therapeutics, Inc. (“Sorrento”), our controlling stockholder, announced that the U.S. Bankruptcy Court for the Southern District of Texas entered an order compelling specified brokerage firms to produce non-privileged written responses to Sorrento providing certain information related to the record and beneficial ownership of our Common Stock received by Sorrento’s stockholders in connection with Sorrento’s previously announced dividend of 76,000,000 shares of our Common Stock held by Sorrento. The order was executed in connection with Sorrento’s chapter 11 case, which was filed on February 13, 2023.

As a result of the foregoing, the Company has determined to postpone the Annual Meeting so as to allow time for the brokerage firms to comply with the order, as the Company anticipates that if the brokerage firms comply with the court’s order, holders of a substantial number of the underreported shares of Common Stock will be able to participate in the Annual Meeting. On April 5, 2023, the Company issued a press release in respect of the foregoing.

The close of business on March 6, 2023, remains as the Record Date for the determination of the stockholders entitled to notice of and to vote at the Annual Meeting and at any adjournments or postponements thereof. In addition, no change has been made to the proposals to come before the Annual Meeting, which were presented in the proxy statement that the Company mailed to stockholders as of the Record Date and filed with the Securities and Exchange Commission on March 8, 2023. Valid proxies that have already been submitted will continue to be valid for purposes of the rescheduled Annual Meeting on Monday, April 17, 2023, and at any adjournments or postponements thereof. The Proxy Materials are available online at www.scilexholding.com.

By order of the Board of Directors,

STOCKHOLDER VOTING INSTRUCTIONS

We will be hosting our Annual Meeting via live audio webcast only. If you are a stockholder as of the Record Date and wish to virtually attend the Annual Meeting, you will need the 16-digit control number, which is located on your proxy card (if you receive a printed copy of the Proxy Materials). Instructions on how to participate in the Annual Meeting are also posted online at www.virtualshareholdermeeting.com/SCLX2023. The webcast will start at 9:00 a.m. Pacific Time on Monday, April 17, 2023. Stockholders may vote and ask questions while attending the Annual Meeting online.

Use of cameras and recording devices are prohibited while virtually attending the live audio webcast.

Registered Stockholders. If shares of our Common Stock are registered directly in your name with our transfer agent, you are considered the stockholder of record (a “stockholder of record”) with respect to those shares, and the Proxy Materials have been provided to you directly by us. As the stockholder of record, you have the right to grant your voting proxy directly to the individuals listed on the proxy card, vote live at the Annual Meeting, or vote by proxy via the Internet.

As a stockholder of record, there are three ways to vote:

If you plan to attend the Annual Meeting, we recommend that you also vote by proxy so that your vote will be counted if you later decide not to attend the Annual Meeting.

Street Name Stockholders. If shares of our Common Stock are held on your behalf in a brokerage account or by a bank or other nominee, you are considered to be the beneficial owner of shares that are held in “street name” (a “street name stockholder”), and the Proxy Materials have been forwarded to you by your broker or nominee, who is considered the stockholder of record with respect to those shares. As the beneficial owner, you have the right to direct your broker, bank or other nominee as to how to vote your shares. Beneficial owners are also invited to attend the Annual Meeting. However, since a beneficial owner is not the stockholder of record, you should follow your broker’s procedures for obtaining a legal proxy to vote your shares of our Common Stock live at the Annual Meeting. If you request a printed copy of our Proxy Materials by mail, your broker, bank or other nominee will provide a voting instruction form for you to use. We refer to stockholders who hold their shares through a broker, bank or other nominee as “street name stockholders.”

As a street name stockholder, you will receive voting instructions from your broker, bank or other nominee. You must follow the voting instructions provided by your broker, bank or other nominee in order to direct your broker, bank or other nominee, as applicable, on how to vote your shares. Street name stockholders should generally be able to vote by returning a voting instruction form or on the Internet. However, the availability of Internet voting will depend on the voting process of your broker, bank or other nominee. As discussed above, if you are a street name stockholder, you must obtain a legal proxy from your broker, bank or other nominee in order to vote your shares by remote communication in the Annual Meeting.

If you have not yet voted, or if you wish to change your vote, you now have an additional opportunity to do so. Only your latest vote will count, and we urge you to vote today.

If you are a stockholder of record, you can change your vote or revoke your proxy any time before the Annual Meeting by:

If you are a street name stockholder, your broker, bank or other nominee can provide you with instructions on how to change or revoke your vote.

Votes will be counted by the inspector of election appointed for the Annual Meeting.
