NOTE 1. DESCRIPTION OF ORGANIZATION AND BUSINESS OPERATIONS

CleanTech Acquisition Corp. (the “Company”) is a blank check company incorporated in Delaware on June 18, 2020. The Company was formed for the purpose of entering into a merger, share exchange, asset acquisition, share purchase, reorganization or similar business combination with one or more businesses or entities (a “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 September 30, 2021, the Company had not commenced any operations. All activity through September 30, 2021 relates to the Company’s formation and the initial public offering (“Initial Public Offering”), which is described below. The Company will not generate any operating revenues until after the completion of a Business Combination, at the earliest. The Company will generate non-operating income in the form of interest income from the proceeds derived from the Initial Public Offering.

The registration statement for the Company’s Initial Public Offering was declared effective on July 14, 2021. On July 19, 2021, the Company consummated the Initial Public Offering of 15,000,000 units (the “Units” and, with respect to the shares of common stock included in the Units sold, the “Public Shares”), at $10.00 per unit, generating gross proceeds of $150,000,000, which is discussed in Note 4.

Simultaneously with the closing of the Initial Public Offering, the Company consummated the sale of 4,333,333 warrants at a price of $1.00 per Private Placement Warrant in a private placement to CleanTech Sponsor (the “Sponsor”), and 2,166,667 warrants (together, the “Private Placement Warrants”) at a price of $1.00 per Private Placement Warrant in a private placement to CleanTech Investments, an affiliate of the Sponsor (the “Co-sponsor”), generating gross proceeds of 6,500,000, which is described in Note 5.

The Company granted the underwriters in the Initial Public Offering (the “Underwriters”) a 45-day option to purchase up to 2,250,000 additional Units to cover over-allotments, if any. On July 28, 2021, the Underwriters exercised the over-allotment option in full and purchased an additional 2,250,000 units (the “Over-Allotment Units”), generating gross proceeds of $22,500,000.

Simultaneously with the closing of the exercise of the over-allotment option, the Company consummated the sale of 675,000 warrants (the “Over-Allotment Warrants”) at a purchase price of $1.00 per warrant in a private placement to the Sponsor, generating gross proceeds of $675,000.

Following the closing of the Initial Public Offering and the over-allotment, an amount of $174,225,000 from the net proceeds of the sale of the Public Units in the Initial Public Offering and the sale of the Private Warrants was placed in a trust account (the “Trust Account”), and was invested only in U.S. government treasury obligations with maturities of 183 days or less or in money market funds meeting certain conditions under Rule 2a-7 under the Investment Company Act of 1940, as amended (the “Investment Company Act”) which invest only in direct U.S. government treasury obligations, until the earlier of: (i) the completion of a Business Combination and (ii) the distribution of the funds held in the Trust Account, as described below.

Transaction costs related to the issuances described above amounted to $3,916,282, consisting of $3,450,000 of cash underwriting fees and $466,282 of other offering costs.

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 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 a Business Combination with one or more target businesses that together have an aggregate fair market value of at least 80% of the value of the Trust Account (as defined below) (excluding the deferred underwriting commissions and taxes payable on income earned on the Trust Account) at the time of the agreement to enter into an initial Business Combination. 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, after signing a definitive agreement for an Initial Business Combination, will either (i) seek stockholder approval of the Initial Business Combination at a meeting called for such purpose in connection with which stockholders may seek to redeem their shares, regardless of whether they vote for or against the Initial Business Combination, for cash equal to their pro rata share of the aggregate amount then on deposit in the Trust Account as of two business days prior to the consummation of the Initial Business Combination, including interest but less taxes payable, or (ii) provide stockholders with the opportunity to sell their Public Shares to the Company by means of a tender offer (and thereby avoid the need for a stockholder vote) for an amount in cash equal to their pro rata share of the aggregate amount then on deposit in the Trust Account as of two business days prior to the consummation of the Initial Business Combination, including interest but less taxes payable. The decision as to whether the Company will seek stockholder approval of the Initial Business Combination or will allow stockholders to sell their Public Shares in a tender offer will be made by the Company, solely in its discretion, and will be based on a variety of factors such as the timing of the transaction and whether the terms of the transaction would otherwise require the Company to seek stockholder approval, unless a vote is required by law or under NASDAQ rules. If the Company seeks stockholder approval, it will complete its Initial Business Combination only if a majority of the outstanding shares of common stock voted are voted in favor of the Initial Business Combination. However, in no event will the Company redeem its Public Shares in an amount that would cause its net tangible assets to be less than $5,000,001 either immediately prior to or upon consummation of the Initial Business Combination. In such case, the Company would not proceed with the redemption of its Public Shares and the related Initial Business Combination, and instead may search for an alternate Initial Business Combination.

If the Company seeks stockholder approval of the initial Business Combination and the Company does not conduct redemptions in connection with the Business Combination pursuant to the tender offer rules, the certificate of incorporation provides that a public stockholder, individually or together with any affiliate of such stockholder or any other person with whom such stockholder is acting in concert or as a “group” (as defined under Section 13 of the Exchange Act), will be restricted from seeking redemption rights with respect to more than an aggregate of 20% of the shares sold in the Initial Public Offering. Furthermore, in order for a public stockholder to have his, her or its shares redeemed for cash in connection with any proposed Business Combination, the Company may require that the public stockholders vote either in favor of or against a proposed Business Combination. If required to vote pursuant to the procedures specified in the proxy statement to stockholders relating to the Business Combination, and a public stockholder fails to vote in favor of or against the proposed Business Combination, whether that stockholder abstains from the vote or simply does not vote, that stockholder would not be able to have his, her or its shares of common stock redeemed to cash in connection with such Business Combination.

The initial stockholders have agreed to waive their redemption rights with respect to any shares they own in connection with the consummation of the initial Business Combination, including their founder shares and public shares that they have purchased during or after the offering, if any. In addition, the initial stockholders have agreed to waive their rights to liquidating distributions with respect to its founder shares if the Company fails to consummate the initial Business Combination within 12 months (or up to 18 months, as applicable) from the closing of the offering. However, if the initial stockholders acquire public shares in or after the Initial Public Offering, they will be entitled to receive liquidating distributions with respect to such public shares if the Company fails to consummate the initial Business Combination within the required time period.

If the Company does not complete a business combination within 12 months (or up to 18 months, as applicable) from the closing this offering (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 100% of the outstanding public shares and (iii) as promptly as reasonably possible following such redemption, subject to the approval of the remaining stockholders and the board of directors, dissolve and liquidate, subject (in the case of (ii) and (iii) above) to the obligations under Delaware 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 warrants, which will expire worthless if the Company fails to complete the Business Combination within the time period.

In order to protect the amounts in the Trust Account, the Sponsor has agreed that it will 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 (i) $10.10 per Public Share or (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 $10.10 per Public Share due to reductions in the value of the trust assets, less taxes payable, provided that such liability will not apply to any claims by a third party or prospective target business who executed a waiver of any and all rights to the monies held in the Trust Account (whether or not such waiver is enforceable) nor will it apply 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”). 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 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.

Going Concern Consideration

As of September 30, 2021, the Company had $789,012 in cash held outside of the Trust Account and working capital of $1,116,854. In connection with the Company’s assessment of going concern considerations in accordance with Financial Accounting Standard Board’s (“FASB”) Accounting Standards Update (“ASU”) 2014-15, “Disclosures of Uncertainties about an Entity’s Ability to Continue as a Going Concern,” management has determined that the date for mandatory liquidation and dissolution raise substantial doubt about the Company’s ability to continue as a going concern through July 19, 2022, the scheduled liquidation date of the Company if it does not complete a Business Combination prior to such date. Management plans to address this uncertainty through the Business Combination as discussed in Note 11 to these financial statements. There is no assurance that the Company's plans to consummate the Business Combination will be successful or successful within the Combination Period. These consolidated 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.

Risks and Uncertainties

Management continues to evaluate the impact of the COVID-19 pandemic on the industry and has concluded that while it is reasonably possible that the virus could have a negative effect on the Company’s financial position, results of its operations, and/or search for a target company, the specific impact is not readily determinable as of the date of these financial statements. The financial statements do not include any adjustments that might result from the outcome of this uncertainty.
