Item 3. Source and Amount of Funds or Other Consideration

The 7,699,449 shares of Class A Common Stock reported herein as being beneficially owned by the Reporting Person were acquired by the Reporting Person on April 20, 2022 in a liquidating distribution by J&A of all of its 28,650,499 shares of Class A Common Stock of the Issuer to all of the shareholders of J&A, pro-rata in accordance with their respective interests in J&A, for no consideration. The Reporting Person held a 27% interest in J&A prior to the liquidating distribution.

The Issuer’s shares that were distributed by J&A were issued to J&A in connection with the completion of the business combination (the “Business Combination”) on January 27, 2022 as contemplated by that certain Business Combination Agreement, dated as of June 28, 2021, as amended on November 30, 2021, January 10, 2022 and January 25, 2022, by and among Trebia Acquisition Corp. (“Trebia”), S1 Holdco, LLC, a Delaware limited liability company (“S1 Holdco”), System1 SS Protect Holdings, Inc., a Delaware corporation (“Protected” and, together with S1 Holdco, the “Companies” or “Old System1”), and the other parties signatory thereto (as it may be amended and/or restated from time to time, the “Business Combination Agreement”).

Prior to the consummation of the transactions contemplated by the Business Combination Agreement, the Reporting Person held an interest in Protected.net Group Limited (“Protected UK”), 94% of which he acquired in 2016 upon Protected UK’s founding, and 6% of which he acquired in 2020. The Reporting Person and the other shareholders (the “Exchanging UK Holders”) of Protected UK exchanged all of their shares of Protected UK for shares of common stock of Protected (the “Protected UK Share Exchange”); and (b) following the Protected UK Share Exchange, the Exchanging UK Holders (other than Lone Star Friends Trust) contributed all of the shares of common stock of Protected received by the Exchanging UK Holders pursuant to the Protected UK Share Exchange to J&A in exchange for ordinary shares of J&A.

Upon the consummation of the merger of Protected with and into Orchid Merger Sub I, Inc. at the closing of the transactions contemplated in the Business Combination Agreement, J&A received, in respect of the cancellation of 6,832,811 shares of common stock of Protected held by J&A, $105,266,634 in cash and 28,650,499 shares of Class A Common Stock of the Issuer.
