Amendment Description	Tiga Acquisition Corp. (the “Company,” “Tiga,” “we,” “us” or “our”) is filing this Amendment No. 1 to its Quarterly Report on Form 10-Q/A for the quarterly period ended September 30, 2021 (this “Amended Form 10-Q”) to amend and restate certain terms in its Quarterly Report on Form 10-Q for the quarterly period ended September 30, 2021 originally filed with the Securities and Exchange Commission (the “SEC”) on November 10, 2021 (the “Original Quarterly Report”). The Company has re-evaluated the Company’s application of ASC 480-10-S99-3A to its accounting classification of the redeemable Class A ordinary shares, par value $0.0001 per share (the “Public Shares”), issued as part of the units sold in the Company’s initial public offering (the “Initial Public Offering”) on November 27, 2020. Historically, a portion of the Public Shares were classified as permanent equity to maintain shareholders’ equity greater than $5,000,000 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. In addition, in connection with the change in presentation for the Public Shares, the Company determined it should restate its earnings per share calculation to allocate income and losses shared pro rata between the two classes of ordinary shares. This presentation contemplates a business combination as the most likely outcome, in which case, both classes of ordinary shares share pro rata in the income and losses of the Company.. Following the filing of the Original Quarterly Report, the Company’s management, together with the Audit Committee, re-evaluated whether the reclassification adjustment related to temporary equity and permanent equity should be restated as of the Initial Public Offering date and the next subsequent reporting periods. Following such re-evaluation, the Company’s management, together with the Audit Committee determined that the Company’s financial statements and other financial data (i) as unaudited interim financial statements as of and for the three months ended March 31, 2021, and (ii) unaudited interim financial statements as of and for the three and six months ended June 30, 2021 (collectively, the “Affected Periods”) should be restated through the filing of this Amended Form 10-Q. The Affected Periods have been restated in Note 2 of this Amended Form 10-Q, with the restatements resulting in a change in the initial carrying value of the Class A ordinary shares subject to possible redemption with the offset recorded to additional paid-in capital (to the extent available), accumulated deficit and Class A ordinary shares. Further, there is no impact to the reported amounts for total assets, total liabilities, cash flows, or net income (loss) but earnings per share was impacted due to a change in presentation relating to the restatements. The financial information that has been previously filed or otherwise reported for the period ended September 30, 2021 is superseded by the information in this Amended Form 10-Q, and the financial statements and related financial information contained in the Original Quarterly Report, filed on November 10, 2021, including the filings for the Affected Periods should no longer be relied upon. On December [], 2021, the Company filed a report on Form 8-K disclosing the non-reliance on the financial statements included in the Original Quarterly Report, as well as the Form 8-K for the Post-Initial Public Offering Audited Balance Sheet as of November 27, 2020 filed on December 3, 2020, the Amended Form 10-K for the year ended December 31, 2020, filed on June 22, 2021 the Form 10-Q for the period ended March 31, 2021 filed on June 22, 2021, and the Form 10-Q for the period ended June 30, 2021 filed on August 13, 2021.
