Description of Organization and Business Operations | NOTE 1 — DESCRIPTION OF ORGANIZATION AND BUSINESS OPERATIONS Avanti Acquisition Corp. (the “Company”) was incorporated in the Cayman Islands on July 24, 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 or entities (the “Business Combination”). The Company is not limited to a particular industry or geographic region for purposes of consummating a Business Combination. The Company is an early stage and emerging growth company and, as such, the Company is subject to all of the risks associated with early stage and emerging growth companies. As of March 31, 2022, the Company had not commenced any operations. All activity through March 31, 2022 relates to the Company’s formation, the initial public offering (the “Initial Public Offering”), which is described below, and identifying a target company for a Business Combination. The Company will not generate any operating revenues until after the completion of its initial Business Combination, at the earliest. The Company generates non-operating The registration statement for the Company’s Initial Public Offering was declared effective on October 1, 2020. On October 6, 2020, the Company consummated the Initial Public Offering of 60,000,000 units (the “Units” and, with respect to the Class A ordinary shares included in the Units sold, the “Public Shares”), generating gross proceeds of $600,000,000 which is described in Note 3. Simultaneously with the closing of the Initial Public Offering, the Company consummated the sale of 14,000,000 warrants (the “Private Placement Warrants”) at a price of $1.00 per Private Placement Warrant in a private placement to Avanti Acquisition SCSp (the “Sponsor”), generating gross proceeds of $14,000,000, which is described in Note 4. Transaction costs amounted to $33,588,903, consisting of $12,000,000 of underwriting fees, $21,000,000 of deferred underwriting fees and $588,903 of other offering costs. Following the closing of the Initial Public Offering on October 6, 2020, an amount of $600,000,000 ($10.00 per Unit) from the net proceeds of the sale of the Units in the Initial Public Offering and the sale of the Private Placement Warrants was placed in a trust account (the “Trust Account”) located in the United States and is invested in U.S. government securities, within the meaning set forth in Section 2(a)(16) of the Investment Company Act of 1940, as amended (the “Investment Company Act”), with a maturity of 185 days or less or in any open-ended investment company that holds itself out as a money market fund selected by the Company meeting the conditions of Rule 2a-7 The Company’s management has broad discretion with respect to the specific application of the net proceeds of the Initial Public Offering 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. So long as the Company’s securities are then listed on the NYSE, the Company’s initial Business Combination must be with one or more target businesses that together have a fair market value of at least 80% of the net assets held in the Trust Account (excluding the amount of deferred underwriting discounts and taxes payable on the income earned) at the time of the signing of the agreement to enter into a Business Combination. The Company will only complete a Business Combination if the post business combination 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. There is no assurance that the Company will be able to complete a Business Combination successfully. The Company will provide the holders of its issued and outstanding Public Shares (the “public shareholders”) 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. 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 $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 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 and who vote 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 its 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 (the “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 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 Sponsor, executive officers and directors (the “initial shareholders”) have agreed to vote their Founder Shares (as defined in Note 4) and any Public Shares purchased during or after the Initial Public Offering in favor of approving a Business Combination. Notwithstanding the foregoing, if the Company seeks shareholder approval of a Business Combination and it does not conduct redemptions pursuant to the tender offer rules, the Amended and Restated Memorandum and Articles of Association provides 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 Public Shares, without the prior consent of the Company. The initial shareholders have agreed to waive their redemption rights with respect to any Founder Shares and Public Shares held by them in connection with (i) the completion of the Company’s initial Business Combination and (ii) a shareholder vote to approve an amendment to the Company’s 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 the Public Shares the right to have their shares redeemed in connection with the Company’s initial Business Combination or to redeem 100% of the Public Shares if the Company does not complete its initial Business Combination by October 6, 2022 or (B) with respect to any other provision relating to the rights of holders of the Public Shares. The Company will have until October 6, 2022 to complete a Business Combination (the “Combination Period”). If the Company has not completed complete 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 aper-shareprice, 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 income taxes (less up to $100,000 of interest to pay dissolution expenses), divided by the number of then issued and outstanding Public Shares, which redemption will completely extinguish public shareholders’ rights as shareholders (including the right to receive further liquidating distributions, if any), and (iii) as promptly as reasonably possible following such redemption, subject to the approval of the Company’s remaining shareholders and the Company’s board of directors, dissolve and liquidate, 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. There will be no redemption rights or liquidating distributions with respect to the Company’s warrants, which will expire worthless if the Company fails to complete a Business Combination within the Combination Period. The initial shareholders have agreed to waive their liquidation rights with respect to the Founder Shares 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, such Public Shares will be entitled to liquidating distributions from the Trust Account 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 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 amounts 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 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 and all rights to seek access to the Trust Account nor 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 (except for the Company’s independent auditors), 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. Going Concern and Liquidity As of March 31, 2022, the Company had $194,134 in its operating bank accounts and working capital deficit of $519,612. Prior to the completion of the Initial Public Offering, the Company’s liquidity needs had been satisfied through a contribution of $25,000 from Sponsor to cover for certain offering costs in exchange for the issuance of the Founder Shares, the loan of up to $300,000 from the Sponsor pursuant to the Promissory Note (see Note 4), advances from the Sponsor, and the proceeds from the consummation of the Private Placement not held in the Trust Account. The Promissory Note and the Advances from Related Party were repaid on October 16, 2020. In addition, in order to finance transaction costs in connection with a Business Combination, the Sponsor or an affiliate of the Sponsor, or certain of the Company’s officers and directors may, but are not obligated to, provide the Company Working Capital Loans up to $1,500,000 (see Note 4). As of March 31, 2022, $843,236 were outstanding under the 2022 Promissory Note (as defined in Note 4). The Company will need to raise additional capital through loans or additional investments from its Sponsor, shareholders, officers, directors, or third parties. The Company’s officers, directors and Sponsor may, but are not obligated to, loan the Company funds, from time to time or at any time, in whatever amount they deem reasonable in their sole discretion, to meet the Company’s working capital needs. Accordingly, the Company may not be able to obtain additional financing. If the Company is unable to raise additional capital, it may be required to take additional measures to conserve liquidity, which could include, but not necessarily be limited to, curtailing operations, suspending the pursuit of a potential transaction, and reducing overhead expenses. The Company cannot provide any assurance that new financing will be available to it on commercially acceptable terms, if at all. These conditions raise substantial doubt about the Company’s ability to continue as a going concern for a reasonable period of time, which is considered to be one year from the issuance date of the condensed financial statements. These condensed financial statements do not include any adjustments relating to the recovery of the recorded assets or the classification of the liabilities that might be necessary should the Company be unable to continue as a going concern.
