Item 5 of the Schedule 13D is hereby amended and restated in its entirety as follows:

(a) – (b)

The following sets forth, as of the date hereof, the aggregate number of shares of Class A Common Stock and percentage of shares of Class A Common Stock beneficially owned by each of the Reporting Persons, as well as the number of shares of Class A Common Stock as to which each Reporting Person has the sole power to vote or to direct the vote, shared power to vote or to direct the vote, sole power to dispose or to direct the disposition of, or shared power to dispose or to direct the disposition of, based on 178,566,352 shares of Class A Common Stock outstanding, as disclosed in the Issuer’s Quarterly Report on Form 10-Q filed with the SEC on May 12, 2022:

BCEC-SIS Holdings L.P. is the beneficial owner of 68,317,440 shares of Class A Common Stock, which includes (i) 68,311,440 shares of Class A Common Stock held of record and (ii) 6,000 shares of Class A Common Stock underlying RSUs that will vest within 60 days.

As a result, Mr. Medina and Medina Capital Fund II—SIS Holdco GP, LLC may be deemed to share voting and investment power over the shares of Class A Common Stock held by Medina Capital Fund II—SIS Holdco, L.P., but each disclaims beneficial ownership of such securities.

In addition, by virtue of the agreements made pursuant to the Stockholders Agreement and the Joinder Agreements, the Investor Parties that continue to beneficially own shares in the Issuer following the Distribution may be deemed to constitute a group for purposes of Rule 13d-3 under the Exchange Act. The Reporting Persons expressly disclaim any beneficial ownership of shares of Class A Common Stock beneficially owned by SVAC Sponsor LLC and such shares are not the subject of this Schedule 13D.
