DESCRIPTION OF ORGANIZATION, BUSINESS OPERATIONS AND BASIS OF PRESENTATION | NOTE 1. DESCRIPTION OF ORGANIZATION, BUSINESS OPERATIONS AND BASIS OF PRESENTATION TortoiseEcofin Acquisition Corp. III (the “Company”) was incorporated as a Cayman Islands exempted company on February 3, 2021. The Company was formed for the purpose of effecting a merger, amalgamation, share exchange, asset acquisition, share purchase, reorganization or similar business combination with one or more businesses or entities (the “Business Combination”). The Company is an emerging growth company and, as such, the Company is subject to all of the risks associated with emerging growth companies. All activity for the period from February 3, 2021 (inception) through March 31, 2023 relates to the Company’s formation and its initial public offering (the “Initial Public Offering”), which is described below, and, subsequent to the Initial Public Offering, the search for a prospective acquisition for an initial Business Combination. The Company will not generate any operating revenues until after the completion of its initial Business Combination, at the earliest. The Company may generate non-operating income in the form of interest income on investments held in trust from the proceeds of its Initial Public Offering. The Company’s fiscal year end is December 31. The Company’s sponsor is TortoiseEcofin Sponsor III LLC, a Cayman Islands limited liability company (the “Sponsor”), which is owned by TortoiseEcofin Investments, LLC, a Delaware limited liability company, and its consolidated subsidiaries (“Tortoise”) and the Company’s management (directly or indirectly, including through family trusts). The registration statement for the Company’s Initial Public Offering was declared effective on July 19, 2021. On July 22, 2021, the Company consummated its Initial Public Offering of 30,000,000 units (the “Units” and, with respect to the Class A ordinary shares included in the Units being offered, the “Public Shares”), at $10.00 per Unit, generating gross proceeds of $300.0 million, and incurring offering costs of approximately $28.3 million, of which $10.5 million was for deferred underwriting commissions (see Note 5) and $11.1 million was the excess of fair value over price paid for Founder Shares sold to certain qualified institutional buyers or institutional accredited investors (the “Anchor Investors”). On July 23, 2021, the underwriters exercised their over-allotment option in full and on July 27, 2021, they purchased 4,500,000 additional Units, generating gross proceeds of $45.0 million (the “Over-Allotment”), and incurring offering costs of approximately $2.5 million, of which approximately $1.6 million was for deferred underwriting commissions. Approximately $1.3 million of the offering costs were allocated to derivative warrant liabilities. The Anchor Investors purchased 32,400,000 Units in the Initial Public Offering and the Over-Allotment. None of the Anchor Investors are affiliated with any member of the Company’s management. Simultaneously with the closing of the Initial Public Offering, the Company completed the sale of 6,333,333 warrants (each, a “Private Placement Warrant” and collectively, the “Private Placement Warrants”) in a private placement (the “Private Placement”), at a price of $1.50 per Private Placement Warrant, to TortoiseEcofin Borrower LLC, a Delaware limited liability company (“TortoiseEcofin Borrower”) and an affiliate of the Sponsor, generating proceeds of $9.5 million (see Note 4). Concurrently with the consummation of the Over-Allotment on July 27, 2021, TortoiseEcofin Borrower purchased 600,000 additional Private Placement Warrants, generating proceeds of $900,000 (the “Second Private Placement”). Upon the closing of the Initial Public Offering and the Private Placement on July 22, 2021, and the Over-Allotment and the Second Private Placement on July 27, 2021, the net proceeds thereof consisting of $345.0 million ($10.00 per Unit) were placed in a trust account (the “Trust Account”), located in the United States with Continental Stock Transfer & Trust Company acting as trustee, and may be invested only 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 money market funds 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. The Company’s management (“management”) has broad discretion with respect to the specific application of the net proceeds of the Initial Public Offering, the Over-Allotment and the sale of the 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 (net of amounts disbursed to management for working capital purposes and excluding the amount of any deferred underwriting discount held in the Trust Account) at the time of the signing of the agreement to enter into the initial Business Combination, and a majority of the independent directors must approve such 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. 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 at $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 its 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 are classified as temporary equity 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 in connection with 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 (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 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) and Tortoise agreed to vote their Founder Shares (as defined below in Note 4) and any Public Shares purchased during or after the Initial Public Offering, and the Anchor Investors agreed to vote any Founder Shares held by them, in favor of a Business Combination. Subsequent to the consummation of the Initial Public Offering, the Company adopted an insider trading policy which requires insiders to: (i) refrain from purchasing shares during certain blackout periods and when they are in possession of any material non-public information and (ii) clear all trades with the Company’s legal counsel prior to execution. In addition, Tortoise and the initial shareholders agreed that they will not be entitled to redemption rights with respect to their Founder Shares 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 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 20% 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 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 July 22, 2023, or 27 months from the closing of the Initial Public Offering, or October 22, 2023, if the Company executed a letter of intent, agreement in principle or definitive agreement for an initial Business Combination within 24 months from the closing of the Initial Public Offering but has not completed the initial Business Combination within such 24-month period (the “Combination Period”) or with respect to any other provision relating to the rights of Public Shareholders, unless the Company will provide the Public Shareholders with the opportunity to redeem their Class A ordinary shares in conjunction with any such amendment. The Anchor Investors are not entitled to (i) redemption rights with respect to any Founder Shares held by them in connection with the completion of a Business Combination, (ii) redemption rights with respect to any Founder Shares held by them in connection with a shareholder vote to amend the Amended and Restated Memorandum and Articles of Association in a manner that would affect the substance or timing of the Company’s obligation to redeem 100% of its Public Shares if the Company has not consummated a Business Combination within the Combination Period or (iii) rights to liquidating distributions from the Trust Account with respect to any Founder Shares held by them if the Company fails to complete a Business Combination within the Combination Period (although they will be entitled to liquidating distributions from the Trust Account with respect to any Public Shares they hold if the Company fails to complete a Business Combination within the Combination Period). 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 its taxes (less up to $100,000 of interest to pay dissolution expenses and net of taxes payable), divided by the number of then outstanding Public Shares, which redemption will completely extinguish the Public Shareholders’ rights as shareholders (including the right to receive further liquidating distributions, if any), subject to applicable law, and (iii) as promptly as reasonably possible following such redemption, subject to the approval of the remaining shareholders and the 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. Tortoise and the initial shareholders agreed to waive their liquidation rights with respect to the Founder Shares 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 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 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 March 31, 2023, the Company had approximately $23,000 in operating cash and working capital of approximately $141,000. The Company’s liquidity needs prior to the consummation of the Initial Public Offering were satisfied through the payment of $25,000 from the Sponsor to cover certain expenses on behalf of the Company in consideration of Founder Shares (as defined in Note 4), and a loan from the Sponsor of approximately $195,000, under the Note (as defined in Note 4). The Company repaid the Note in full on July 22, 2021 and borrowings under the Note are no longer available. Subsequent to the consummation of the Initial Public Offering, the Company’s liquidity has been satisfied through the net proceeds of $3.5 million from the consummation of the Initial Public Offering, the Over-Allotment, the Private Placement and the Second Private Placement held outside of the Trust Account. In addition, in order to finance general working capital needs 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 (as defined in Note 4). On February 1, 2023, the Company issued a nonconvertible, unsecured promissory note (the “2023 Note”) in the principal amount of $500,000 to TortoiseEcofin Borrower. The 2023 Note does not bear interest and is repayable in full upon consummation of a Business Combination. If the Company does not complete a Business Combination, the 2023 Note will not be repaid and all amounts owed under it will be forgiven. As of March 31, 2023 and December 31, 2022, there were $150,000 and $0, respectively, outstanding under Working Capital Loans. See Note 4. In connection with the Company’s assessment of going concern considerations in accordance with FASB ASC Topic 205-40, “Presentation of Financial Statements-Going Concern,” management has determined that the liquidity condition and mandatory liquidation and subsequent dissolution raise substantial doubt about the Company’s ability to continue as a going concern. The Company intends to complete a Business Combination before the mandatory liquidation date; however, there can be no assurance that the Company will be able to consummate a Business Combination by July 22, 2023, or 27 months from the closing of the Initial Public Offering, or October 22, 2023, if the Company executed a letter of intent, agreement in principle or definitive agreement for a Business Combination within 24 months from the closing of the Initial Public Offering but has not completed such Business Combination within such 24-month period. No adjustments have been made to the carrying amounts of assets or liabilities should the Company be required to liquidate after July 22, 2023. The financial statements do not include any adjustment that might be necessary if the Company is unable to continue as a going concern. |
