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 June 30, 2022, the Company had not commenced any operations. All activity for the three and six months ended June 30, 2022 and 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 generates 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 3.

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 4.

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 is 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.

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.

On July 19, 2022, the Company filed an amendment to the Amended and Restated Certificate of Incorporation with the Delaware Secretary of State (the “Charter Amendment”), giving the Company the right to extend the date by which it has to complete a business combination up to six (6) times for an additional one (1) month each time, from July 19, 2022 to January 19, 2023 (the “Combination Period”). If the Company does not 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 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.

Business Combination Agreement

On December 16, 2021, the Company entered into an Agreement and Plan of Merger, as amended on January 30, 2022 through Amendment No. 1 (the “Merger Agreement,” and together with the other agreements and transactions contemplated by the Merger Agreement, the “Business Combination”) with CleanTech Merger Sub, Inc., a Delaware corporation and a wholly owned subsidiary of CleanTech (“Merger Sub”), and Nauticus Robotics, Inc., a Texas corporation (“Nauticus”). Pursuant to the terms of the Merger Agreement, a business combination between CleanTech and Nauticus will be effected through the merger of Merger Sub with and into Nauticus, with Nauticus surviving the merger as a wholly owned subsidiary of CleanTech (the “Merger”). The Board of Directors of CleanTech (the “Board”) has unanimously (i) approved and declared advisable the Merger Agreement, the Merger and the other transactions contemplated thereby and (ii) resolved to recommend approval of the Merger Agreement and related matters by the stockholders of CleanTech.

Preferred Stock. Immediately prior to the effective time of the Merger (the “Effective Time”), each share of Nauticus Preferred Stock that is issued and outstanding immediately prior to such time shall automatically convert into shares of Nauticus Common Stock, par value $0.01 per share (the “Nauticus Common Stock”), in accordance with its Certificate of Incorporation (collectively, the “Nauticus Preferred Stock Conversion”). An aggregate of 15,062,524 shares of CLAQ Common Stock will be issued to the holders of Nauticus Preferred Stock.

Convertible Notes. Immediately prior to the Effective Time, each of (i) that certain Unsecured Convertible Promissory Note, dated June 19, 2021, by and between Goradia Capital, LLC and Nauticus, as amended on December 16, 2021, (ii) that certain Unsecured Convertible Promissory Note, August 3, 2021, by and between Material Impact Fund II, L.P. and Nauticus, as amended on December 16, 2021, (iii) that certain Unsecured Convertible Promissory Note, dated October 22, 2021, by and between In-Q-Tel, Inc. and Nauticus, as amended on December 16, 2021, (iv) that certain Unsecured Convertible Promissory Note, dated July 28, 2020, by and between Schlumberger Technology Corporation and Nauticus, as amended on December 16, 2021, and (v) that certain Unsecured Convertible Promissory Note, dated December 7, 2020, by and between Transocean Inc. and Nauticus, as amended on December 16, 2021 (each, a “Nauticus Convertible Note” and collectively, the “Nauticus Convertible Notes”) shall automatically convert into shares of Nauticus Common Stock in accordance with the terms of each such Nauticus Convertible Note (collectively, the “Nauticus Convertible Notes Conversion”). An aggregate of 5,299,543 shares of CLAQ Common Stock will be issued to the holders of Nauticus Convertible Notes.

Common Stock. At the Effective Time, following the Nauticus Preferred Stock Conversion and Nauticus Convertible Notes Conversion, each share of Nauticus Common Stock (including shares of Nauticus Common Stock outstanding as a result of the Nauticus Preferred Stock Conversion and Nauticus Convertible Notes Conversion, but excluding shares of the holders of which perfect rights of appraisal under Delaware law) will be converted into the right to receive the applicable Per Share Merger Consideration (as defined below) and the Earnout Shares (as defined below). An aggregate of 9,669,216 shares of CLAQ Common Stock will be issued to the holders of Nauticus Common Stock.

Stock Options. At the Effective Time, each outstanding option to purchase shares of Nauticus Common Stock (a “Nauticus Option”), whether or not then vested and exercisable, will be assumed by CLAQ and converted automatically (and without any required action on the part of such holder of outstanding option) into an option to purchase shares of the CLAQ’s Common Stock equal to the number of shares determined by multiplying the number of shares of the Nauticus Common Stock subject to such Nauticus Option immediately prior to the Effective Time by the Exchange Ratio (as defined below), which product shall be rounded down to the nearest whole number of shares, at a per share exercise price determined by dividing the per share exercise price of such Nauticus Option immediately prior to the Effective Time by the Exchange Ratio. Options to purchase an aggregate of 4,055,704 shares of CLAQ Common Stock will be issued to the holders of Nauticus Options.

Earnout Shares. Following the closing of the merger, former holders of shares of Nauticus Common Stock (including shares received as a result of the Nauticus Preferred Stock conversion and the Nauticus Convertible Notes conversion) shall be entitled to receive their pro rata share of up to 7,500,000 additional shares of CleanTech Common Stock (the “Earnout Shares”) if, within a 5-year period following the signing date of the Merger Agreement, the closing share price of the CleanTech Common Stock equals or exceeds any of three thresholds over any 20 trading days within a 30-day trading period (each, a “Triggering Event”).

On or about December 14, 2021, the Company entered into subscription agreements, with certain investors pursuant to which, among other things, the Company agreed to issue and sell, in a private placement to close immediately prior to the closing of the Business Combination, an aggregate of 3,530,000 shares of common stock for $10.00 per share for a total of $35,300,000 (the “Equity Financing”). On December 16, 2021, the Company entered into a Securities Purchase Agreement (as further described below) with certain investors purchasing up to an aggregate of $40,000,000 in principal amount of secured debentures (the “Debentures”) and warrants (the “Warrants”) with an exercise price of $20.00 substantially concurrently with the closing of the Business Combination (the “Debt Financing,” and together with the Equity Financing, the “PIPE Investment”). As of June 30, 2022, ATW Special Situations I LLC (“ATW”) is the only purchaser and has subscribed for Debentures in the aggregate principal amount of $37,959,184 and associated warrants for 3,036,735 shares of the Combined Company’s common stock. ATW is managed by ATW Partners Opportunities Management, LLC, which is an affiliate of Chardan Capital Markets, LLC (“Chardan”), and the Company’s director, Mr. Jonas Grossman, is the Managing Partner and President of Chardan. Chardan will not receive any fees or compensation for ATW’s participation in the Debt Financing.

It is anticipated that upon completion of the Business Combination, CLAQ’s public stockholders (other than the PIPE Investment investors) would retain an ownership interest of approximately 28.5% in the Combined Company, the PIPE Investment investors will own approximately 5.6% of the Combined Company (such that the public stockholders, including the PIPE Investment investors, would own approximately 34.1% of the Combined Company), the Co-Sponsors, officers, directors and other holders of founder shares will retain an ownership interest of approximately 6.8% of the Combined Company and the Nauticus stockholders will own approximately 59.1% (including the 7,500,000 Earnout Shares) of the Combined Company. The ownership percentage with respect to the Combined Company does not take into account (i) the redemption of any shares by the CLAQ’s public stockholders or (ii) the issuance of any additional shares upon the closing of the Business Combination under the 2015 Equity Incentive Plan. If the actual facts are different from these assumptions (which they are likely to be), the percentage ownership retained by the CLAQ stockholders will be different.

The Merger Agreement contains customary representations and warranties of the parties thereto with respect to, among other things, (a) entity organization, good standing and qualification, (b) capital structure, (c) authorization to enter into the Merger Agreement, (d) compliance with laws and permits, (e) taxes, (f) financial statements and internal controls, (g) real and personal property, (h) material contracts, (i) environmental matters, (j) absence of changes, (k) employee matters, (l) litigation, and (m) brokers and finders.

The Merger Agreement includes customary covenants of the parties with respect to operation of their respective businesses prior to consummation of the Merger and efforts to satisfy conditions to consummation of the Merger. The Merger Agreement also contains additional covenants of the parties, including, among others, covenants providing for CleanTech and Nauticus to use reasonable best efforts to cooperate in the preparation of the Registration Statement and Proxy Statement (as each such term is defined in the Merger Agreement) required to be filed in connection with the Merger and to obtain all requisite approvals of their respective stockholders including, in the case of CleanTech, approvals of the restated certificate of incorporation, the share issuance under Nasdaq rules and the omnibus incentive plan. CleanTech has also agreed to include in the Proxy Statement the recommendation of its board that stockholders approve all of the proposals to be presented at the special meeting.

CleanTech has agreed to approve and adopt a 2022 omnibus incentive plan (the “Incentive Plan”) to be effective as of the closing and in a form mutually acceptable to CleanTech and Nauticus. The Incentive Plan shall provide for an initial aggregate share reserve equal to 5% of the number of shares of CleanTech Common Stock on a fully diluted basis at the closing. Subject to approval of the Incentive Plan by CleanTech’s stockholders, CleanTech has agreed to file a Form S-8 Registration Statement with the SEC following the Effective Time with respect to the shares of CleanTech Common Stock issuable under the Incentive Plan.

Each of CleanTech and Nauticus has agreed that from the date of the Merger Agreement to the Effective Time or, if earlier, the valid termination of the Merger Agreement in accordance with its terms, it will not initiate any negotiations with any party, or provide non-public information or data concerning it or its subsidiaries to any party relating to an Acquisition Proposal or Alternative Transaction (as such terms are defined in the Merger Agreement) or enter into any agreement relating to such a proposal. Each of CleanTech and Nauticus has also agreed to use its reasonable best efforts to prevent any of its representatives from doing the same.

The consummation of the Merger is conditioned upon, among other things, (i) receipt of the CleanTech stockholder approval and Nauticus stockholder approval, (ii) the expiration or termination of the waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, (iii) the absence of any governmental order, statute, rule or regulation enjoining or prohibiting the consummation of the Transactions, (iv) the effectiveness of the Registration Statement under the Securities Act, (v) CleanTech having at least $5,000,001 of net tangible assets (as determined in accordance with Rule 3a51-1(g)(1) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”)), (vi) solely with respect to CleanTech, (A) the representations and warranties of Nauticus being true and correct to applicable standards applicable and each of the covenants of Nauticus having been performed or complied with in all material respects and (B) the approval of the conversion of the convertible notes and (vii) solely with respect to Nauticus, (A) the representations and warranties of CleanTech being true and correct to applicable standards applicable and each of the covenants of CleanTech having been performed or complied with in all material respects (B) the receipt of the approval for listing by Nasdaq of the shares of CleanTech Common Stock to be issued in connection with the transactions contemplated by the Merger Agreement, (C) the effective resignations of certain directors and executive officers of CleanTech, (D) the amount of Minimum Cash Condition (as defined in the Merger Agreement) being equal to or exceeding $50,000,000.

On June 6, 2022, the Parties to the Merger Agreement entered into Amendment No. 2 to the Merger Agreement (the “Amendment”) pursuant to which the Parties agreed to increase the aggregate number of shares of the Post-Combination Company’s Common Stock to be reserved for issuance under its Incentive Plan from 5% to 10% of the fully diluted outstanding shares of its Common Stock immediately after Closing, which share reserve shall be automatically increased on an annual basis by 3% of the total number of Common Stock outstanding as provided under the Incentive Plan.

Other Agreements

The Business Combination Agreement contemplates the execution of various additional agreements and instruments, on or before the Closing, including, among others, the following:

Support Agreements

In connection with the execution of the Merger Agreement, CleanTech Sponsor I LLC and CleanTech Investments, LLC (each, a “Sponsor,” and collectively, the “Co-Sponsors”) entered into a support agreement (the “Sponsor Support Agreement”) with Nauticus pursuant to which the Sponsors have agreed to vote all shares of CleanTech Common Stock beneficially owned by them in favor of the Merger.

In addition, in connection with the execution of the Merger Agreement, certain stockholders of Nauticus owning approximately 88.8% of the voting power of Nauticus entered into a support agreement (the “Nauticus Support Agreement”) with CleanTech and Nauticus pursuant to which the stockholders agreed to vote all shares of Nauticus beneficially owned by them in favor of the Merger.

Subscription Agreements

In connection with the execution of the Merger Agreement, CleanTech entered into subscription agreements (collectively, the “Subscription Agreements”) with certain parties subscribing for shares of CleanTech Common Stock (the “Subscribers”) pursuant to which the Subscribers have agreed to purchase, and CleanTech has agreed to sell to the Subscribers, an aggregate of 3,530,000 shares of CleanTech Common Stock, for a purchase price of $10.00 per share and an aggregate purchase price of $35.3 million. The obligations to consummate the transactions contemplated by the Subscription Agreements are conditioned upon, among other things, customary closing conditions and the consummation of the transactions contemplated by the Merger Agreement.

Securities Purchase Agreement

In connection with the execution of the Merger Agreement, CleanTech and Nauticus entered into Securities Purchase Agreement with certain investors purchasing up to an aggregate of $40,000,000 in principal amount of Debentures and Warrants.

The obligations to consummate the transactions contemplated by the Securities Purchase Agreement are conditioned upon, among other things, customary closing conditions and all conditions precedent to the Merger set forth in the Merger Agreement shall have been satisfied or waived.

Amended and Restated Registration Rights Agreement

In connection with the Closing, Nauticus, CleanTech and certain stockholders of each of Nauticus and CleanTech who will receive shares of CleanTech Common Stock pursuant to the Merger Agreement, will enter into an amended and restated registration rights agreement (“Registration Rights Agreement”) mutually agreeable to CleanTech and Nauticus, which will become effective upon the consummation of the Merger.

Lock-up Agreement and Arrangements

In connection with the Closing, the Sponsors and certain Nauticus stockholders will enter into a lock-up agreement (the “Sponsor Lock-Up Agreement” and “Company Stockholder Lock-up Agreement) with Nauticus and CleanTech, pursuant to which each will agree, subject to certain customary exceptions, not to:

(i) offer, sell, contract to sell, pledge or otherwise dispose of, directly or indirectly, any shares of CleanTech Common Stock received as merger consideration and held by it immediately after the Effective Time (the “Lock-Up Shares”), or enter into a transaction that would have the same effect;

(ii) enter into transaction that would have the same effect, or enter into any swap, hedge or other arrangement that transfers, in whole or in part, any of the economic consequences of ownership of any of such shares, whether any of these transactions are to be settled by delivery of such shares, in cash or otherwise; or

(iii) publicly disclose the intention to make any offer, sale, pledge or disposition, or to enter into any transaction, swap, hedge or other arrangement, or engage in any “Short Sales” (as defined in the Sponsor Lock-Up Agreement and Company Stockholder Lock-up Agreement) with respect to any security of CleanTech; during a “Lock-Up Period” under their respective agreements.

Under the Sponsor Lock-up Agreement, the Lock-Up period means the period commencing on the Closing Date and ending on the earlier of (x) the one year anniversary of the Closing Date; (y) the date on which the volume weighted average price of shares of Common Stock equals or exceeds $13.00 per share for twenty (20) of any thirty (30) consecutive trading days commencing after the Closing on Nasdaq, and (z) the date specified in a written waiver duly executed by Nauticus; provided that the restrictions set forth in the Sponsor Lock-up Agreement do not apply to (1) transfers or distributions to such stockholder’s current or former general or limited partners, managers or members, stockholders, other equity holders or direct or indirect affiliates (within the meaning of Rule 405 under the Securities Act of 1933, as amended) or to the estates of any of the foregoing; (2) transfers by bona fide gift to a member of the stockholder’s immediate family or to a trust, the beneficiary of which is the stockholder or a member of the stockholder’s immediate family for estate planning purposes; (3) by virtue of the laws of descent and distribution upon death of the stockholder; or (4) pursuant to a qualified domestic relations order, in each case where such transferee agrees to be bound by the terms of the Sponsor Lock-up Agreement.

Director Nomination Agreement

Director Designation Agreement

In connection with the execution of the Merger Agreement, CleanTech, Nauticus and certain Nauticus stockholders entered into a director designation agreement with Transocean, Inc. (“Transocean”) to take all necessary action to cause a member designated by Transocean (the “Transocean Designee”) to remain on, or otherwise be appointed to, the Board, from and after the effective time of the Merger, as a Class III member of the Board, for an initial term expiring at the third annual meeting following the date of the Second Amended and Restated Certificate of Incorporation to be adopted in connection with the Merger.

Indemnification Agreements

In connection with the Closing, CleanTech has agreed to enter into customary indemnification agreements, in form and substance reasonably acceptable to CleanTech and Nauticus, with the individuals who will be nominated and, subject to stockholder approval, elected to CleanTech’s board of directors effective as of the Closing.

Going Concern Consideration

As of June 30, 2022, the Company had $172,785 in cash held outside of the Trust Account and working capital deficit of $1,755,090. As a result of the above, in connection with the Company’s assessment of going concern considerations in accordance with Financial Accounting Standards Board (“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 liquidity condition and date for mandatory liquidation and dissolution raise substantial doubt about the Company’s ability to continue as a going concern through August 19, 2023, the scheduled liquidation date of the Company if it does not complete a Business Combination prior to such date. These unaudited condensed 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.

Principles of Consolidation

The accompanying unaudited condensed consolidated financial statements include the accounts of the Company and its wholly-owned subsidiary. All significant intercompany balances and transactions have been eliminated in consolidation.

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 unaudited condensed consolidated financial statements. The unaudited condensed consolidated financial statements do not include any adjustments that might result from the outcome of this uncertainty.

In February 2022, the Russian Federation and Belarus commenced a military action with the country of Ukraine. As a result of this action, various nations, including the United States, have instituted economic sanctions against the Russian Federation and Belarus. Further, the impact of this action and related sanctions on the world economy is not determinable as of the date of these unaudited condensed consolidated financial statements. The specific impact on the Company’s financial condition, results of operations, and cash flows is also not determinable as of the date of these unaudited condensed consolidated financial statements.

Pursuant to the Initial Public Offering which was consummated on July 19, 2021, the Company sold 15,000,000 Units at a purchase price of $10.00 per Unit. Each Unit consists of one share of the Company’s common stock, $0.0001 par value, one right entitling the holder thereof to receive one-twentieth (1/20) of one share common stock upon the consummation of an initial business combination, and one-half of one redeemable warrant (“Redeemable Warrant”). Each whole Redeemable Warrant is exercisable to purchase one share of common stock and only whole warrants are exercisable. No fractional warrants will be issued upon separation of the Units and only whole warrants will trade. The Redeemable Warrants will become exercisable on the later of 30 days after the completion of the Initial Business Combination or 12 months from the closing of the Initial Public Offering. Each whole Redeemable Warrant entitles the holder to purchase one share of common stock at an exercise price of $11.50 (see Note 7).

On July 26, 2021, the underwriters fully exercised the over-allotment option and purchased an additional 2,250,000 Units (the “Over-Allotment Units”), generating gross proceeds of $22,500,000 on July 28, 2021.

Simultaneously with the closing of the Initial Public Offering, the Sponsor and Co-Sponsor purchased an aggregate of 6,500,000 Private Warrants at a price of $1.00 per Private Placement Warrant ($6,500,000 in the aggregate). Each Private Placement Warrant is exercisable to purchase one share of common stock at a price of $11.50 per share. Simultaneously with the sale of Over-Allotment Units, the Company consummated a private sale of an additional 675,000 Private Warrants at a purchase price of $1.00 per Private Warrant, generating gross proceeds of $675,000. The proceeds from the sale of the Private Warrants were added to the net proceeds from the Initial Public Offering held in the Trust Account. If the Company does not complete a Business Combination within the Combination Period, the proceeds from the sale of the Private Warrants will be used to fund the redemption of the Public Shares (subject to the requirements of applicable law) and the Private Placement Warrants will expire worthless.

Founder Shares

In July 2020, the Sponsor was issued 5,000,000 shares of Common Stock (the “Founder Shares”) for an aggregate price of $25,000. In February 2021, the Company effected a 1.4375-for-1 stock split of its issued and outstanding shares of Common Stock, resulting in an aggregate of 4,312,500 Founder Shares issued and outstanding. The Founder Shares included an aggregate of up to 562,500 shares of Common Stock subject to forfeiture by the Sponsor to the extent that the underwriters’ over-allotment option is not exercised in full or in part, so that the Sponsor will own, on an as-converted basis, 20% of the Company’s issued and outstanding shares after the Initial Public Offering.

In June 2021, CleanTech Sponsor and CleanTech Investments forfeited for no consideration 1,916,667 founder shares and 958,333 founder shares, respectively, which the Company cancelled, resulting in a decrease in the total number of founder shares outstanding from 7,187,500 shares to 4,312,500 shares. As a result, CleanTech Sponsor owns 2,875,000 founder shares and CleanTech Investments owns 1,437,500 founder shares. The founder shares include an aggregate of up to 562,500 shares that are subject to forfeiture to the extent that the underwriters’ over-allotment option is not exercised in full or in part. All share and per-share amounts have been retroactively restated to reflect the share forfeiture.

The underwriter exercised the over-allotment option on in full July 28, 2021; thus, no Founders Shares are subject to forfeiture.

Administrative Services Agreement

The Company entered into an agreement, commencing on the July 14, 2021, to pay Chardan Capital Markets, LLC up to $10,000 per month for office space, administrative and support services. The total amounts of administrative service fees accrued for the three months ended June 30, 2022 and 2021 were $30,000 and $0, respectively. The total amounts of administrative service fees accrued for the six months ended June 30, 2022 and 2021 were $60,000 and $0, respectively. As of June 30, 2022 and December 31, 2021, $60,000 and $0 were owed to the Sponsor, respectively. Upon completion of the Business Combination or the Company’s liquidation, the Company will cease paying these monthly fees.

Promissory Note - Related Party

On March 1, 2021, the Company issued an unsecured promissory note to the Sponsor (the “Promissory Note”), pursuant to which the Company could borrow an aggregate of up to $250,000 to cover expenses related to the Initial Public Offering. The Promissory Note was non-interest bearing and is payable on the earlier of Promptly after the date on which the Company consummates an Initial Public Offering of its securities or (ii) the completion of the Initial Public Offering. The outstanding balance under the Promissory Note of $188,302 was repaid on July 23, 2021. The promissory note is no longer available to the Company.

On March 23, 2022, the Company entered into a Promissory Note with the Sponsor (the “Second Promissory Note”) to which the Company could borrow up to an aggregate of $267,000. The Second Promissory Note is non-interest bearing and payable upon the earlier of (i) completion of the initial Business Combination or (ii) the date on which the Company determines that it is unable to effect a Business Combination. As June 30, 2022, the outstanding balance under the Second Promissory Note was $267,000.

Related Party Loans

In addition, in order to finance transaction costs in connection with an intended initial Business Combination, the Company’s Sponsor, Co-Sponsor, or an affiliate of the Sponsor or the officers and directors may, but are not obligated to, loan the Company funds as may be required. If the Company consummates the initial Business Combination, it would repay such loaned amounts. The notes would either be paid upon consummation of the Company’s initial Business Combination, without interest, or, at the lender’s discretion, up to $500,000 of the notes may be converted upon consummation of the Business Combination into additional private warrants to purchase shares of common stock at a conversion price of $1.00 per private warrant (which, for example, would result in the holders being issued private warrants to purchase 500,000 shares of common stock if $500,000 of notes were so converted). Such private warrants will be identical to the private warrants issued at the closing of the Initial Public Offering. Loans made by Chardan Capital Markets, LLC or any of its related persons will not be convertible into private warrants, and Chardan Capital Markets, LLC and its related persons will have no recourse with respect to their ability to convert their loans into private warrants. As of June 30, 2022 and December 31, 2021, there were no borrowings under these loans.

Related Party Extension Loans

The Company may extend the period of time to consummate a Business Combination up to two times, each by an additional three months (for a total of 18 months to complete a Business Combination). In order to extend the time available for the Company to consummate a Business Combination, without the need for a separate stockholder vote, is for the Company’s initial stockholders or their affiliates or designees, upon five days’ advance notice prior to the application deadline, to deposit into the trust account $1,500,000 or $1,725,000 if the underwriters’ over-allotment option is exercised in full ($0.10 per public share, or an aggregate of $3,000,000 (or $3,450,000 if the over-allotment option is exercised in full) if extended for each of the full three months), on or prior to the date of the application deadline. In the event that the stockholders, or affiliates or designees, elect to extend the time to complete the Company’s initial business combination and deposit the applicable amount of money into trust, the initial stockholders will receive a non-interest bearing, unsecured promissory note equal to the amount of any such deposit that will not be repaid in the event that the Company is unable to close a business combination unless there are funds available outside the trust account to do so. Such note would be paid upon consummation of the Company’s initial Business Combination.

Registration and Stockholder Rights Agreement

Pursuit to a registration rights agreement entered into on July 14, 2021, the holders of insider shares issued and outstanding, as well as the holders of the private warrants (and all underlying securities), will be entitled to registration and stockholder rights pursuant to an agreement to be signed prior to or on the effective date of the Initial Public Offering. The holders of a majority of these securities are entitled to make up to two demands that the Company registers such securities. The holders of the majority of the insider shares can elect to exercise these registration rights at any time commencing three months prior to the date on which these shares of Common Stock are to be released from escrow. In addition, the holders have certain “piggy-back” registration rights with respect to registration statements filed subsequent to the consummation of a Business Combination. The Company will bear the expenses incurred in connection with the filing of any such registration statements.

Underwriter’s Agreement

The Company granted the underwriter a 45-day option to purchase up to 2,250,000 additional Units to cover over-allotments at the Initial Public Offering price, less the underwriting discounts and commissions. On July 28, 2021, the Underwriters exercised the over-allotment option in full and purchased an additional 2,250,000 Units for an aggregate purchase price of $22,500,000.

In connection with the closing of the Initial Public Offering and subsequent exercise of the over-allotment option, the underwriter was paid a cash underwriting fee of $0.20 per Unit, or $3,450,000 in the aggregate.

Business Combination Marketing Agreement

The Company engaged Chardan Capital Markets, LLC as an advisor in connection with the initial Business Combination to assist the Company in holding meetings with the stockholders to discuss the potential Business Combination and the target business’s attributes, introduce the Company to potential investors that are interested in purchasing the securities in connection with the potential Business Combination, assist the Company in obtaining stockholder approval for the Business Combination and assist the Company with press releases and public filings in connection with the Business Combination. The Company will pay Chardan Capital Markets, LLC a marketing fee for such services upon the consummation of the initial Business Combination in an amount equal to, in the aggregate, 3.5% of the gross proceeds of the Initial Public Offering, including any proceeds from the full or partial exercise of the underwriters’ over-allotment option. As a result, Chardan Capital Markets, LLC will not be entitled to such fee unless the Company consummates the initial Business Combination. A copy of the form of Business Combination marketing agreement has been filed as an exhibit to the registration statement of which the Company’s prospectus forms a part.

As of June 30, 2022 and December 31, 2021, there were 15,800,000 (including 8,625,000 Public Warrants and 7,175,000 Private Placement Warrants) warrants outstanding.

Each whole public warrant entitles the registered holder to purchase one share of Common Stock at a price of $11.50 per whole share, subject to adjustment as described below, at any time commencing on the later of one year after the closing of the Initial Public Offering or the consummation of an initial Business Combination. However, no public warrants will be exercisable for cash unless the Company has an effective and current registration statement covering the shares of Common Stock issuable upon exercise of the warrants and a current prospectus relating to such shares of Common Stock. Notwithstanding the foregoing, if a registration statement covering the shares of Common Stock issuable upon exercise of the public warrants is not effective within 120 days from the closing of the initial Business Combination, warrant holders may, until such time as there is an effective registration statement and during any period when the Company shall have failed to maintain an effective registration statement, exercise warrants on a cashless basis pursuant to an available exemption from registration under the Securities Act. The warrants will expire five years from the closing of the initial Business Combination at 5:00 p.m., New York City time.

If the Company calls the warrants for redemption as described above, the Company’s management will have the option to require all holders that wish to exercise warrants to do so on a “cashless basis.” In such event, each holder would pay the exercise price by surrendering the warrants for that number of shares of common stock equal to the quotient obtained by dividing (x) the product of the number of shares of common stock underlying the warrants, multiplied by the difference between the exercise price of the warrants and the “fair market value” by (y) the fair market value. The “fair market value” shall mean the average reported last sale price of the Company’s common stock for the 10 trading days ending on the third trading day prior to the date on which the notice of redemption is sent to the holders of warrants. Whether the Company will exercise the option to require all holders to exercise their warrants on a “cashless basis” will depend on a variety of factors including the price of the common shares at the time the warrants are called for redemption, the Company’s cash needs at such time and concerns regarding dilutive share issuances.

The exercise price and number of shares of common stock issuable on exercise of the warrants may be adjusted in certain circumstances including in the event of a share dividend, extraordinary dividend or the Company’s recapitalization, reorganization, merger or consolidation. In addition, if the Company issues additional shares of common stock or equity-linked securities for capital raising purposes in connection with the closing of the initial Business Combination at a newly issued price of less than $9.20 per share of common stock (with such issue price or effective issue price to be determined in good faith by the board of directors and, in the case of any such issuance to the Company’s initial stockholders or their affiliates, without taking into account any founder shares or private warrants held by them, as applicable, prior to such issuance), the exercise price of the warrants will be adjusted (to the nearest cent) to be equal to 115% of the newly issued price and the $16.50 per share redemption trigger price described below under will be adjusted (to the nearest cent) to be equal to 165% of the market value (the volume weighted average trading price of the common stock during the 20 trading day period starting on the trading day prior to the consummation of an initial Business Combination).

The warrants may be exercised upon surrender of the warrant certificate on or prior to the expiration date at the offices of the warrant agent, with the exercise form on the reverse side of the warrant certificate completed and executed as indicated, accompanied by full payment of the exercise price, by certified or official bank check payable to us, for the number of warrants being exercised. The warrant holders do not have the rights or privileges of holders of shares of common stock and any voting rights until they exercise their warrants and receive shares of common stock. After the issuance of shares of common stock upon exercise of the warrants, each holder will be entitled to one vote for each share held of record on all matters to be voted on by stockholders.

Except as described above, no public warrants will be exercisable for cash, and the Company will not be obligated to issue shares of common stock unless at the time a holder seeks to exercise such warrant, a prospectus relating to the shares of common stock issuable upon exercise of the warrants is current and the shares of common stock have been registered or qualified or deemed to be exempt under the securities laws of the state of residence of the holder of the warrants. Under the terms of the warrant agreement, the Company has agreed to use best efforts to meet these conditions and to maintain a current prospectus relating to the shares of common stock issuable upon exercise of the warrants until the expiration of the warrants. However, the Company cannot assure you that it will be able to do so and, if the Company does not maintain a current prospectus relating to the shares of common stock issuable upon exercise of the warrants, holders will be unable to exercise their warrants, and the Company will not be required to settle any such warrant exercise. If the prospectus relating to the shares of common stock issuable upon the exercise of the warrants is not current or if the common stock is not qualified or exempt from qualification in the jurisdictions in which the holders of the warrants reside, the Company will not be required to net cash settle or cash settle the warrant exercise, the warrants may have no value, the market for the warrants may be limited, and the warrants may expire worthless.

No fractional shares will be issued upon exercise of the warrants. If, upon exercise of the warrants, a holder would be entitled to receive a fractional interest in a share, the Company will, upon exercise, round down to the nearest whole number the number of shares of common stock to be issued to the warrant holder.

The Company accounts for the 15,800,000 warrants issued in connection with the Initial Public Offering in accordance with the guidance contained in ASC 815-40. Such guidance provides that because the warrants do not meet the criteria for equity treatment thereunder, each warrant must be recorded as a liability.

The accounting treatment of derivative financial instruments required that the Company record the warrants as derivative liabilities at fair value upon the closing of the Initial Public Offering. The Public Warrants were allocated a portion of the proceeds from the issuance of the Units equal to its fair value. This warrant liabilities are subject to re-measurement at each balance sheet date. With each such re-measurement, the warrant liability will be adjusted to its current fair value, with the change in fair value recognized in the Company’s condensed consolidated statements of operations. The Company will reassess the classification at each balance sheet date. If the classification changes as a result of events during the period, the warrants will be reclassified as of the date of the event that causes the reclassification.

Preferred stock — The Company is authorized to issue 1,000,000 shares of $0.0001 par value preferred stock. As of June 30, 2022 and December 31, 2021, there were no shares of preferred stock issued or outstanding.

Common stock — On July 16, 2021, the Company amended its Amended and Restated Certificate of Incorporation such that the Company is authorized to issue 200,000,000 shares of common stock with a par value of $0.0001 per share. As of June 30, 2022 and December 31, 2021, there were 21,562,500 shares of common stock outstanding, including 17,250,000 common stock subject to possible redemption.

Holders of record of common stock are entitled to one vote for each share held on all matters to be voted on by stockholders. In connection with any vote held to approve the initial Business Combination, insiders, officers and directors, have agreed to vote their respective shares of common stock owned by them immediately prior to the Initial Public Offering, including both the insider shares and any shares acquired in the Initial Public Offering or following the Initial Public Offering in the open market, in favor of the proposed Business Combination.

Rights — Except in cases where the Company is not the surviving company in a Business Combination, each holder of a right will automatically receive one-twentieth (1/20) of a share of common stock upon consummation of the Business Combination, even if the holder of a right converted all shares held by him, her or it in connection with the Business Combination or an amendment to the Company’s Certificate of Incorporation with respect to its pre-business combination activities. In the event that the Company will not be the surviving company upon completion of the Business Combination, each holder of a right will be required to affirmatively convert his, her or its rights in order to receive the one-twentieth (1/20) of a share of common stock underlying each right upon consummation of the Business Combination. No additional consideration will be required to be paid by a holder of rights in order to receive his, her or its additional share of common stock upon consummation of the Business Combination. The shares issuable upon exchange of the rights will be freely tradable (except to the extent held by affiliates of the Company). If the Company enters into a definitive agreement for a Business Combination in which the Company will not be the surviving entity, the definitive agreement will provide for the holders of rights to receive the same per share consideration the holders of shares of common stock will receive in the transaction on an as-converted into common stock basis.

The Company will not issue fractional shares in connection with an exchange of rights. As a result, the holders of the rights must hold rights in multiples of 20 in order to receive shares for all of the holders’ rights upon closing of a Business Combination. If the Company is unable to complete an initial Business Combination within the required time period and the Company liquidates the funds held in the Trust Account, holders of rights will not receive any of such funds with respect to their rights, nor will they receive any distribution from the Company’s assets held outside of the Trust Account with respect to such rights, and the rights will expire worthless. Additionally, in no event will the Company be required to net cash settle the rights. Accordingly, the rights may expire worthless.

The Company's effective tax rate for the three and six months ended June 30, 2022 was (1.6)% and 1.1%, respectively. The effective tax rate for the three and six months ended June 30, 2021 was 0.0%. The Company's effective tax rate differs from the statutory income tax rate of 21% primarily due to the recognition of gains or losses from the changes in the fair value of warrant liabilities and the convertible promissory note, which are not recognized for tax purposes, and recording a full valuation allowance on deferred tax assets. The Company has historically calculated the provision for income taxes during interim reporting periods by applying an estimate of the annual effective tax rate for the full fiscal year to income or loss for the reporting period. The Company has used a discrete effective tax rate method to calculate taxes for the three and six months ended June 30, 2022. The Company believes that, at this time, the use of the discrete method for the three and six months ended June 30, 2022 is more appropriate than the estimated annual effective tax rate method as the estimated annual effective tax rate method is not reliable due to a high degree of uncertainty in estimating annual pretax earnings.

The following table presents information about the Company’s financial assets and liabilities that are measured at fair value on a recurring basis as of June 30, 2022 and December 31, 2021, and indicates the fair value hierarchy of the valuation inputs the Company utilized to determine such fair value:

The Company utilized a Monte Carlo simulation model for the initial valuation of the Public Warrants, and the publicly-traded value for the subsequent valuation of the Public Warrants. The measurement of the Public Warrants as of June 30, 2022 and December 31, 2021 is classified as Level 1 due to the use of an observable market quote in an active market under the ticker CLAQW. The quoted price of the Public Warrants was $0.32 and $0.60 per warrant as of June 30, 2022 and December 31, 2021, respectively.

The Company utilizes a Black-Scholes Option Pricing Model to value the Private Placement Warrants at each reporting period, with changes in fair value recognized in the condensed consolidated statements of operations. The estimated fair value of the warrant liability is determined using Level 3 inputs. Inherent in a Black-Scholes Option Pricing Model are assumptions related to expected share-price volatility, expected life, risk-free interest rate and dividend yield. For the initial valuation, the Company estimated volatility based on research on comparable companies with the same type of warrants along with the implied volatilities shortly after they start trading. Significant increases (decreases) in the expected volatility in isolation would result in a significantly higher (lower) fair value measurement. The risk-free interest rate is based on the U.S. Treasury zero-coupon yield curve on the grant date for a maturity similar to the expected remaining life of the warrants. The expected life of the warrants is assumed to be equivalent to their remaining contractual term. The dividend rate is based on the historical rate, which the Company anticipates to remain at zero.

Transfers to/from Levels 1, 2 and 3 are recognized at the end of the reporting period. The estimated fair value of the Public Warrants transferred from a Level 3 measurement to a Level 1 fair value measurement in September 2021 after the Public Warrants were separately listed and traded.

The following table provides the significant inputs to the Black-Scholes Option Pricing Model fair value of the Private Placement Warrants:

The following table provides a summary of the changes in the fair value of the Company’s Level 3 financial instruments that are measured at fair value on a recurring basis:

The Company recognized gains in connection with the change in the fair value of warrant liabilities of $503,750 and $0 in the unaudited condensed consolidated statements of operations for the three months ended June 30, 2022 and 2021, respectively. The Company recognized gains in connection with the change in the fair value of warrant liabilities of $2,917,250 and $0 in the unaudited condensed consolidated statements of operations for the six months ended June 30, 2022 and 2021, respectively.

The Company evaluated subsequent events and transactions that occurred after the condensed consolidated balance sheet date up to the date that the condensed consolidated financial statements were issued. Based upon this review, other than those identified below, the Company did not identify any subsequent events that would have required adjustment or disclosure in the condensed consolidated financial statements.

As approved by the Company’s stockholders at a Special Meeting of Stockholders on July 18, 2022 (the “Meeting”), the Company entered into an amendment (the “Trust Amendment”) to the investment management trust agreement, dated as of July 14, 2021, with Continental Stock Transfer & Trust Company on July 19, 2022. Pursuant to the Trust Amendment, the Company has the right to extend the time to complete a business combination six (6) times for an additional one (1) month each time from July 19, 2022, to January 19, 2023, by depositing $100,000 to the trust account for each one-month extension.

As approved by the Company’s stockholders at the Meeting on July 18, 2022, the Company filed an amendment to its Amended and Restated Certificate of Incorporation with the Delaware Secretary of State on July 19, 2022 (the “Charter Amendment”), giving the Company the right to extend the date by which it has to complete a business combination up to six (6) times for an additional one (1) month each time, from July 19, 2022 to January 19, 2023.

On July 18, 2022, the Company issued an unsecured promissory note in the aggregate principal amount of $150,000 to CleanTech Investments, LLC and an unsecured promissory note in the aggregate principal amount of $300,000 to CleanTech Sponsor I LLC. The Company deposited to the Trust Account $100,000 of the total $450,000 of loan amount and extended the amount of time it has available to complete a business combination from July 19, 2022 to August 19, 2023. Both CleanTech Investments, LLC and CleanTech Sponsor I LLC are the Company’s sponsors at its initial public offering. Neither promissory note bears interest and both of them will be repaid only upon closing of a business combination by the Company.

On August 12, 2022, the Company exercised its right to extend the date by which it has to complete a business combination for an additional one (1) month, from August 19, 2022 to September 19, 2022, and deposited an additional $100,000 to the Trust Account.
