As previously reported on the Current Report on Form 8-K filed with the Securities and Exchange Commission (“SEC”) on February 3, 2022, SilverBox held a special meeting, at which SilverBox’s shareholders voted to approve the proposals outlined in the proxy statement filed by SilverBox with the SEC on January 13, 2022 (the “Proxy Statement/Prospectus”), including, among other things, the adoption of the Business Combination Agreement and approval of the other transactions contemplated by the Business Combination Agreement.

On February 9, 2022 (the “Closing Date”), as contemplated by the Business Combination Agreement and as described in the section titled “Proposal No. 1—The Business Combination Proposal” beginning on page 128 of the Proxy Statement/Prospectus, (i) SilverBox merged with and into Merger Sub 1 (the “SilverBox Merger”), with Merger Sub 1 surviving the SilverBox Merger as a direct wholly-owned subsidiary of PubCo, and (ii) immediately following the SilverBox Merger, Merger Sub 2 merged with and into Blocker (the “Blocker Merger” and, together with the SilverBox Merger and all other transactions contemplated by the Business Combination Agreement, the “Business Combination”), with Blocker surviving as a wholly-owned subsidiary of Merger Sub 1.

At closing of the Business Combination (the “Closing”), and pursuant to the terms of the Business Combination Agreement, the following occurred:
