Amendment Description	Alberton Acquisition Corporation (the “Company”, “we”, “our” or “us”) is filing this Amendment No. 2 to its Annual Report on Form 10-K (this “Amendment”) to amend and restate certain items of its Annual Report on Form 10-K for the year ended December 31, 2020, originally filed with the U.S. Securities and Exchange Commission (the “SEC”) on April 6, 2021, as amended on June 22, 2021 (the “Original Filing”) to restate our financial statements as of and for the year ended December 31, 2020 included in the Company’s Annual Report on Form 10-K filed with the SEC on April 6, 2021, as amended on June 22, 2021 (the “Original Financial Statements”).Restatement BackgroundThe Company has re-evaluated the Company’s application of ASC 480-10-S99-3A to its accounting classification of the redeemable ordinary shares, no par value (the “Public Shares”), issued as part of the units sold in the Company’s initial public offering (the “IPO”) on October 26, 2018 and in connection with the partial exercise of the over-allotment option on November 20, 2018. Historically, a portion of the Public Shares was classified as permanent equity to maintain shareholders’ equity greater than $5 million on the basis that the Company will not redeem its Public Shares in an amount that would cause its net tangible assets to be less than $5,000,001, as described in the Company’s amended and restated memorandum and articles of association (the “Charter”). Pursuant to such re-evaluation, the Company’s management has determined that the Public Shares include certain provisions that require classification of all of the Public Shares as temporary equity regardless of the net tangible assets redemption limitation contained in the Charter. This has resulted in a restatement of the initial carrying value of the Public Shares subject to possible redemption, with the offset recorded to additional paid-in capital (to the extent available), accumulated deficit and shares of Public Shares.Therefore, the Company, in consultation with the audit committee of the Company’s board of directors (the “Audit Committee”), concluded that its previously issued financial statements for the periods ended March 31, 2019, June 30, 2019, September 30, 2019, December 31, 2019, March 31, 2020, June 30, 2020, September 30, 2020, December 31, 2020, March 31, 2021, June 30, 2021 and September 30, 2021 (collectively, the “Affected Periods”) should be restated because of a misapplication in the guidance around accounting for Public Shares should no longer be relied upon. As such, the Company will restate its financial statements in this Form 10-K/A for the Affected Periods (excluding the periods ended March 31, 2021, June 30, 2021 and September 31, 2021 to be restated in a subsequent filing) to report all Public Shares as temporary equity.The restatement does not have an impact on its cash position and cash held in the trust account established in connection with the IPO (the “Trust Account”).
