Organization, Consolidation and Presentation of Financial Statements [Abstract]
Description of Organization, Business Operations and Basis of Presentation	Note 1—Description of Organization, Business Operations and Basis of Presentation Investindustrial Acquisition Corp. (the “Company”) was incorporated as a Cayman Islands exempted company on September 7, 2020. The Company was formed for the purpose of effecting a merger, share exchange, asset acquisition, share purchase, reorganization or similar business combination with one or more businesses (the “Business Combination”). Although the Company is not limited to a particular industry or geographic region for purposes of consummating its Business Combination, the Company intends to capitalize on the ability of its management team to identify, acquire and manage a business in the industrial and consumer sectors. The Company is an emerging growth company and, as such, the Company is subject to all of the risks associated with emerging growth companies. As of December 31, 2020, the Company had not commenced any operations. All activity for the period from September 7, 2020 (inception) through December 31, 2020 relates to the Company’s formation and the preparation of its initial public offering (the “Initial Public Offering”) described below. The Company will not generate any operating revenues until after the completion of its initial Business Combination, at the earliest. The Company will generate non-operating income in the form of interest income on cash and cash equivalents from the proceeds derived from the Initial Public Offering. The Company has selected December 31 as its fiscal year end. The Company’s sponsor is Investindustrial Acquisition Corp. L.P, a limited partnership incorporated in England and Wales (the “Sponsor”). The registration statement for the Company’s Initial Public Offering was declared effective on November 18, 2020. On November 23, 2020, the Company consummated its Initial Public Offering of 35,000,000 units (each, a “Unit” and collectively, the “Units” and, with respect to the Class A ordinary shares included in the Units, the “Public Shares”) at an offering price of $ 10.00 per Unit, generating gross proceeds of $ 350.0 million, and incurring offering costs of approximately $ 20.2 million, inclusive of approximately $ 12.3 million in deferred underwriting commissions (Note 5). The Company granted the underwriters of the Initial Public Offering (the “Underwriters”) a 45-day option from the date of the final prospectus relating to the Initial Public Offering to purchase up to 5,250,000 additional Units to cover over-allotments (the “Over-Allotment Option”), if any, at $ 10.00 per Unit. On November 24, 2020, the Underwriters fully exercised the Over-Allotment Option to purchase an additional 5,250,000 Units (the “Over-Allotment Units”). On November 27, 2020, the Company completed the sale of the Over-Allotment Units to Underwriters (the “Over-Allotment”), generating gross proceeds of $ 52.5 million, and incurred additional offering costs of approximately $ 2.9 million in underwriting fees (inclusive of approximately $ 1.8 million in deferred underwriting commissions) (Note 6). Simultaneously with the closing of the Initial Public Offering, the Company completed a private placement (the “Private Placement”) of 6,000,000 warrants (each, a “Private Placement Warrant” and collectively, the “Private Placement Warrants”) at a price of $1.50 per Private Placement Warrant to the Sponsor, generating proceeds of $9.0 million. Simultaneously with the closing of the Over-Allotment Units, on November 27, 2020, the Company consummated a second private placement (the “Second Private Placement”), resulting in the purchase of an aggregate of an additional 700,000 Private Placement Warrants by the Sponsor, generating gross proceeds to the Company of approximately $1.1 million. Upon the closing of the Initial Public Offering and the Private Placement, an aggregate of $350.0 million ($10.00 per Unit), consisting of $343.0 million of net proceeds of the Initial Public Offering and $7.0 million of the gross proceeds of the Private Placement, was placed in a trust account (“Trust Account”), located in the United States at J.P. Morgan Chase Bank, N.A., with Continental Stock Transfer & Trust Company acting as trustee, and is invested only in U.S. government securities, within the meaning set forth in Section 2(a)(16) of the Investment Company Act, with a maturity of 185 days or less or in money market fund meeting the conditions of paragraphs (d)(1), (d)(2), (d)(3) and (d)(4) of Rule 2a-7 of the Investment Company Act, as determined by the Company, until the earlier of: (i) the completion of a Business Combination and (ii) the distribution of the Trust Account as described below. Upon closing of the Over-Allotment and the Second Private Placement, an aggregate of $52.5 million ($10.00 per Unit) was placed in the Trust Account, for a total of $402.5 million deposited in the Trust Account. The Company’s management has broad discretion with respect to the specific application of the net proceeds of the Initial Public Offering, Over- Allotment, and the sale of Private Placement Warrants, although substantially all of the net proceeds are intended to be applied generally toward consummating a Business Combination. There is no assurance that the Company will be able to complete a Business Combination successfully. The Company must complete one or more initial Business Combinations having an aggregate fair market value of at least 80% of the net assets held in the Trust Account (as defined below) (excluding the amount of deferred underwriting commissions and taxes payable on the interest earned on the Trust Account) at the time of the signing of the agreement to enter into the initial Business Combination. However, the Company will only complete a Business Combination if the post-transaction company owns or acquires 50% or more of the outstanding voting securities of the target or otherwise acquires a controlling interest in the target sufficient for it not to be required to register as an investment company under the Investment Company Act of 1940, as amended (the “Investment Company Act”). The Company will provide the holders (the “Public Shareholders”) of Public Shares, with the opportunity to redeem all or a portion of their Public Shares upon the completion of a Business Combination either (i) in connection with a shareholder meeting called to approve the Business Combination or (ii) by means of a tender offer. The decision as to whether the Company will seek shareholder approval of a Business Combination or conduct a tender offer will be made by the Company, solely in its discretion. The Public Shareholders will be entitled to redeem their Public Shares for a pro rata portion of the amount then in the Trust Account (initially anticipated to be $10.00 per Public Share, plus any pro rata interest earned on the funds held in the Trust Account and not previously released to the Company to pay income taxes). The per-share amount to be distributed to Public Shareholders who redeem their Public Shares will not be reduced by the deferred underwriting commissions the Company will pay to the Underwriters (as discussed in Note 5). These Public Shares will be classified as temporary equity upon the completion of the Initial Public Offering in accordance with the Financial Accounting Standards Board’s (“FASB”) Accounting Standards Codification (“ASC”) Topic 480 “Distinguishing Liabilities from Equity.” In such case, the Company will proceed with a Business Combination if the Company has net tangible assets of at least $5,000,001 upon such consummation of a Business Combination and, only if a majority of the ordinary shares, represented in person or by proxy and entitled to vote thereon, voted at a shareholder meeting are voted in favor of the Business Combination. If a shareholder vote is not required by law and the Company does not decide to hold a shareholder vote for business or other reasons, the Company will, pursuant to the amended and restated memorandum and articles of association which the Company adopted upon the consummation of the Initial Public Offering (the “Amended and Restated Memorandum and Articles of Association”), conduct the redemptions pursuant to the tender offer rules of the U.S. Securities and Exchange Commission (“SEC”) and file tender offer documents with the SEC prior to completing a Business Combination. If, however, shareholder approval of the transactions is required by law, or the Company decides to obtain shareholder approval for business or other reasons, the Company will offer to redeem shares in conjunction with a proxy solicitation pursuant to the proxy rules and not pursuant to the tender offer rules. Additionally, each Public Shareholder may elect to redeem their Public Shares irrespective of whether they vote for or against the proposed transaction or vote at all. If the Company seeks shareholder approval in connection with a Business Combination, the initial shareholders (as defined below) have agreed to vote their Founder Shares (as defined below in Note 4) and any Public Shares purchased during or after the Initial Public Offering in favor of a Business Combination. In addition, the initial shareholders have agreed to waive their redemption rights with respect to their Founder Shares, Private Placement Warrants and Public Shares in connection with the completion of a Business Combination. Notwithstanding the foregoing, if the Company seeks shareholder approval of its Business Combination and does not conduct redemptions in connection with its Business Combination pursuant to the tender offer rules, the Amended and Restated Memorandum and Articles of Association provide that a Public Shareholder, together with any affiliate of such shareholder or any other person with whom such shareholder is acting in concert or as a “group” (as defined under Section 13 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”)), will be restricted from redeeming its shares with respect to more than an aggregate of 15% of the Class A ordinary shares sold in the Initial Public Offering, without the prior consent of the Company. The Company’s Sponsor, officers and directors (the “initial shareholders”) have agreed not to propose an amendment to the Amended and Restated Memorandum and Articles of Association (a) that would modify the substance or timing of the Company’s obligation to provide holders of its Public Shares the right to have their shares redeemed in connection with a Business Combination or to redeem 100% of the Company’s Public Shares if the Company does not complete its Business Combination within 24 months from the closing of the Initial Public Offering, or November 23, 2022 (the “Combination Period”) or with respect to any other provision relating to the rights of Public Shareholders, unless the Company provides the Public Shareholders with the opportunity to redeem their Class A ordinary shares in conjunction with any such amendment. If the Company has not completed a Business Combination within the Combination Period, the Company will (i) cease all operations except for the purpose of winding up; (ii) as promptly as reasonably possible but not more than ten business days thereafter, redeem the Public Shares, at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account, including interest earned on the funds held in the Trust Account and not previously released to the Company to pay for its income taxes, if any (less up to $100,000 of interest to pay dissolution expenses), divided by the number of the then-outstanding Public Shares, which redemption will completely extinguish Public Shareholders’ rights as shareholders (including the right to receive further liquidation distributions, if any); and (iii) as promptly as reasonably possible following such redemption, subject to the approval of the Company’s remaining shareholders and its board of directors, liquidate and dissolve, subject in the case of clauses (ii) and (iii) to the Company’s obligations under Cayman Islands law to provide for claims of creditors and the requirements of other applicable law. The initial shareholders have agreed to waive their liquidation rights with respect to the Founder Shares and Private Placement Warrants held by them if the Company fails to complete a Business Combination within the Combination Period. However, if the initial shareholders acquire Public Shares in or after the Initial Public Offering, they will be entitled to liquidating distributions from the Trust Account with respect to such Public Shares if the Company fails to complete a Business Combination within the Combination Period. The Underwriters have agreed to waive their rights to their deferred underwriting commission (see Note 5) held in the Trust Account in the event the Company does not complete a Business Combination within the Combination Period and, in such event, such amounts will be included with the other funds held in the Trust Account that will be available to fund the redemption of the Public Shares. In the event of such distribution, it is possible that the per share value of the assets remaining available for distribution (including Trust Account assets) will be only $10.00 per share initially held in the Trust Account. In order to protect the amounts held in the Trust Account, the Sponsor has agreed to be liable to the Company if and to the extent any claims by a third party for services rendered or products sold to the Company, or a prospective target business with which the Company has discussed entering into a transaction agreement, reduce the amount of funds in the Trust Account to below the lesser of (i) $10.00 per Public Share and (ii) the actual amount per Public Share held in the Trust Account as of the date of the liquidation of the Trust Account if less than $10.00 per Public Share due to reductions in the value of the trust assets. This liability will not apply with respect to any claims by a third party who executed a waiver of any right, title, interest or claim of any kind in or to any monies held in the Trust Account or to any claims under the Company’s indemnity of the Underwriters of the Initial Public Offering against certain liabilities, including liabilities under the Securities Act of 1933, as amended (the “Securities Act”). Moreover, in the event that an executed waiver is deemed to be unenforceable against a third party, the Sponsor will not be responsible to the extent of any liability for such third-party claims. The Company will seek to reduce the possibility that the Sponsor will have to indemnify the Trust Account due to claims of creditors by endeavoring to have all vendors, service providers (excluding the Company’s independent registered public accounting firm), prospective target businesses or other entities with which the Company does business, execute agreements with the Company waiving any right, title, interest or claim of any kind in or to monies held in the Trust Account. Liquidity and Capital Resources As of December 31, 2020, the Company had approximately $1,044,000 in its operating bank account, working capital of approximately $586,000, and cash and marketable securities held in the Trust Account of $402,500,000. The Company’s liquidity needs up to December 31, 2020 had been satisfied through $25,000 paid by the Sponsor to cover certain expenses on the Company’s behalf in exchange for the issuance of the Founder Shares (as defined below), a loan of approximately $61,000 pursuant to the Note issued to the Sponsor, and an additional loan of approximately $66,000 from the Sponsor, for a total amount of approximately $127,000 under the Note, and the proceeds from the consummation of the Private Placement not held in the Trust Account. The Company repaid the Note in full on December 11, 2020 (Note 4). In addition, in order to finance transaction costs in connection with a Business Combination, the Sponsor may, but is not obligated to, provide the Company Working Capital Loans (see Note 4). The Company has no borrowings outstanding under Working Capital Loans to date. Based on the foregoing, management believes that the Company will have sufficient working capital and borrowing capacity to meet its needs through the earlier of the consummation of a Business Combination or one year from this filing. Over this time period, the Company will be using these funds held outside the Trust Account for paying existing accounts payable, identifying and evaluating prospective initial Business Combination candidates, performing due diligence on prospective target businesses, paying for travel expenditures, selecting the target business to merge with or acquire, and structuring, negotiating and consummating the Business Combination. We intend to use substantially all of the funds held in the Trust Account, including any amounts representing interest earned on the Trust Account (less taxes payable) to complete our initial business combination. We may withdraw interest from the trust account to pay franchise and income taxes. To the extent that the Company’s equity or debt is used, in whole or in part, as consideration to complete the initial business combination, the remaining proceeds held in the Trust Account will be used as working capital to finance the operations of the target business or businesses, make other acquisitions, and pursue growth strategies. Risks and Uncertainties Management continues to evaluate the impact of the COVID-19 pandemic and has concluded that while it is reasonably possible that it could have a negative effect on the Company’s financial position, results of operations and/or search of a target company, the specific impact is not readily determinable as of the date of the audited financial statements were available to be issued. The audited financial statements do not include any adjustments that might result from the outcome of this uncertainty. Basis of Presentation The accompanying financial statements are presented in U.S. dollars in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”) and pursuant to the rules and regulations of the SEC. Accordingly, they do not include all of the information and footnotes required by GAAP. In the opinion of management, the audited financial statements reflect all adjustments, which include only normal recurring adjustments necessary for the fair statement of the balances and results for the periods presented. As described in Note 2—Restatement of Previously Issued Financial Statements, the Company’s financial statements as of December 31, 2020 and for the period from September 7, 2020 (inception) through December 31, 2020, are restated in this Annual Report on Form 10-K/A (Amendment No. 2) (this “Annual Report”) to correct the misapplication of accounting guidance related to the Company’s warrants in the Company’s previously issued audited financial statements for such periods. The restated financial statements are indicated as “Restated” in the financial statements and accompanying notes, as applicable. See Note 2—Restatement of Previously Issued Financial Statements for further discussion.
