Item 1.01. Entry into a Material Definitive Agreement.

On July 14, 2021, the registration statement (File No. 333-256578) (the “Registration Statement”) relating to the initial public offering (“IPO”) of CleanTech Acquisition Corp. (the “Company”) was declared effective by the Securities and Exchange Commission. In connection therewith, the Company entered into the following agreements previously filed as exhibits to the Registration Statement:

On July 19, 2021, the Company consummated the IPO of 15,000,000 units (the “Units”). Each Unit consists of one share of common stock, $0.0001 par value (“Common Stock”), one right entitling the holder thereof to receive one-twentieth (1/20) of one share of Common Stock upon the consummation of an initial business combination, and one-half of one warrant entitling the holder thereof to purchase one share of Common Stock at a price of $11.50 per whole share. The Units were sold at an offering price of $10.00 per Unit, generating gross proceeds of $150,000,000. The Company granted the underwriters a 45-day option to purchase up to 2,250,000 additional Units to cover over-allotments, if any.

As of July 19, 2021, a total of $151,500,000 of the net proceeds from the IPO and the Private Placement (as defined below) were deposited in a trust account established for the benefit of the Company’s public stockholders. An audited balance sheet as of July 19, 2021 reflecting receipt of the proceeds upon consummation of the IPO and the Private Placement will be filed within 4 business days of the consummation of the IPO.

Item 3.02. Unregistered Sales of Equity Securities.

Simultaneously with the closing of the IPO, the Company consummated the private placement (the “Private Placement”) with initial stockholders of the Company of 6,500,000 warrants (the “Private Warrants”), generating total proceeds of $6,500,000.

The Private Warrants are identical to the warrants sold as part of the public Units in this offering except that the Private Warrants will be non-redeemable and may be exercised on a cashless basis, in each case so long as they continue to be held by the initial purchasers or their permitted transferees, as further described in the Registration Statement. Such initial purchasers were granted certain demand and piggyback registration rights in connection with the purchase of the Private Warrants.

The Private Warrants were issued pursuant to Section 4(a)(2) of the Securities Act of 1933, as amended, as the transactions did not involve a public offering.

Item 5.03. Amendments to Certificate of Incorporation or Bylaws; Change in Fiscal Year.

On July 14, 2021, in connection with the IPO, the Company filed its Amended and Restated Certificate of Incorporation with the Delaware Secretary of State. The terms of the Amended and Restated Certificate of Incorporation are set forth in the Registration Statement and are incorporated herein by reference.
