Item 4.01. Changes in Registrant’s Certifying Accountant.
On February 24, 2022, the Audit Committee of the board of directors (the “Board”) of System1, Inc. (the “Company”) approved management’s recommendation to appoint PricewaterhouseCoopers LLP (“PwC”) as the Company’s independent registered public accounting firm for the Company’s fiscal year ending December 31, 2022 and to dismiss Marcum LLP (“Marcum”) as the Company’s independent registered public accounting firm, effective upon the Company’s filing of its Annual Report on Form 10-K for the fiscal year ended December 31, 2021 and the fiscal period from February 11, 2020 (inception) to December 31, 2020, which consists only of the accounts of the pre-Business Combination (as defined below) special purpose acquisition company, Trebia Acquisition Corp., a Cayman Islands exempted company (“Trebia”).
On January 27, 2022, Trebia completed a previously announced business combination (the “Business Combination”) pursuant to that certain business combination agreement, as amended on November 30, 2021, January 10, 2022 and January 25, 2022, by and among S1 Holdco, LLC, a Delaware limited liability company (“S1 Holdco”), System1 SS Protect Holdings, Inc., a Delaware corporation, and the other parties signatory thereto, filed as Exhibit 2.1 to the Company’s Current Report on Form 8-K filed with the Securities and Exchange Commission (“SEC”) on June 29, 2021. For accounting purposes, S1 Holdco was determined to be the predecessor entity of the Company. The historical financial statements of the predecessor entity, S1 Holdco, which have been audited by PwC, will become the historical financial statements of the Company.
The report of Marcum on Trebia’s balance sheet as of December 31, 2020 and the statements of operations, changes in stockholders’ equity and cash flows for the period from February 11, 2020 (inception) to December 31, 2020, did not contain an adverse opinion or a disclaimer of opinion, and was not qualified or modified as to uncertainties, audit scope or accounting principles, except for an explanatory paragraph regarding Trebia’s ability to continue as a going concern.
During the period from February 11, 2020 (inception) to December 31, 2020, the year ended December 31, 2021 and through March 2, 2022, there were no disagreements between the Company and Marcum on any matter of accounting principles or practices, financial disclosure or auditing scope or procedure, which disagreements, if not resolved to the satisfaction of Marcum, would have caused it to make reference to the subject matter of the disagreements in its report on Trebia’s financial statements for such period.
During the period from February 11, 2020 (inception) to December 31, 2020, the year ended December 31, 2021, and subsequent interim period through March 2, 2022, there have been no “reportable events” (as defined in Item 304(a)(1)(v) of Regulation S-K), other than the material weaknesses in Trebia’s internal controls identified by management related to complex financial instruments which resulted in the restatement of Trebia’s financial statements as set forth in Trebia’s Form 10-K for the fiscal year ended December 31, 2020 as filed with the SEC on December 1, 2021 and Forms 10-Q for the quarters ended June 30, 2020 and September 30, 2020 as filed with the SEC on August 14, 2020 and November 12, 2020, respectively.
The Company has provided Marcum with a copy of the foregoing disclosures and has requested that Marcum furnish the Company with a letter addressed to the SEC stating whether it agrees with the statements made by the Company set forth above. A copy of Marcum’s letter, dated March 2, 2022, is filed as Exhibit 16.1 to this Current Report.
PwC served as independent registered public accounting firm of S1 Holdco prior to the Business Combination. During the fiscal years ended December 31, 2020, and December 31, 2021, and the subsequent interim period through February 24, 2022, neither the Company nor anyone on its behalf has consulted with PwC regarding (i) the application of accounting principles to a specific transaction, either completed or proposed, or the type of audit opinion that might be rendered on the Company’s financial statements, where either a written report or oral advice was provided to the Company that PwC concluded was an important factor considered by the Company in reaching a decision as to the accounting, auditing or financial reporting issue, (ii) any matter that was the subject of a disagreement within the meaning of Item 304(a)(1)(iv) of Regulation S-K and the related instructions to Item 304 of Regulation S-K or (iii) any reportable event within the meaning of Item 304(a)(1)(v) of Regulation S-K.
