On July 18, 2021, ECP Environmental Growth Opportunities Corp., a Delaware corporation (“ENNV”), and ENNV Merger Sub, Inc., a Delaware corporation and wholly owned subsidiary of ENNV (“Merger Sub”), entered into an Agreement and Plan of Merger (as it was amended, supplemented or otherwise modified from time to time in accordance with its terms, the “Merger Agreement”) with Fast Radius, pursuant to which Merger Sub will merge with and into Fast Radius, with Fast Radius surviving the merger as a wholly owned subsidiary of ENNV (the “Merger” and, together with the other transactions contemplated by the Merger Agreement, the “Business Combination”). On February 4, 2022, pursuant to the Merger Agreement, Fast Radius consummated the Business Combination. Subject to the terms of the Merger Agreement, all of the issued and outstanding shares of Fast Radius were converted into an aggregate of (i) 65,000,000 shares of Common Stock, par value $0.0001 per share, of ENNV at a deemed value of $10.00 per share (including 11,196,271 shares of Common Stock underlying exchanged options, vested RSUs and exchanged RSUs) and (ii) the contingent right to receive during the earnout period certain additional shares of the Company’s common stock as specified in the Merger Agreement (the “Merger Earnout Shares”), in two equal tranches of 5,000,000 shares of the Company’s Common Stock, upon the satisfaction of certain price targets set forth in the Merger Agreement. The transaction provided all holders of the Company’s Common Stock with shares of Common Stock of the continuing public company. Upon close of the Business Combination, ENNV changed its name to Fast Radius, Inc. and the Company changed its name to Fast Radius Operations, Inc. As of December 31, 2021, the Company capitalized $3.6 million in direct and incremental equity issuance-related transaction costs within prepaid expenses and other current assets on the consolidated balance sheet, of which $3.1 million was not yet paid as of December 31, 2021 and was presented within accrued and other liabilities on the consolidated balance sheet. The Company’s basis of presentation within these consolidated financial statements do not reflect any adjustment as a result of the Merger closing. The Merger will be accounted for as a reverse recapitalization. Under this method of accounting, Fast Radius will be treated as the accounting acquirer for financial reporting purposes. Refer to Note 15 for further information regarding the Business Combination. Basis of Presentation The accompanying consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”). No transactions have been recorded to accumulated other comprehensive income or loss through December 31, 2021. Principles of Consolidation The Company’s consolidated financial statements reflect its financial statements and those of its wholly owned subsidiary. All intercompany transactions and balances have been eliminated in consolidation. Risks and Uncertainties The Company is subject to a number of risks similar to those of other companies of similar size in its industry, including, but not limited to, the need for successful development of products, new customer acquisition, the need for additional funding, competition from substitute products and services from larger companies, protection of proprietary technology, dependence on key individuals, and risks associated with changes in information technology. The Company has financed its operations through issuances of debt and preferred stock since inception. The Company’s long-term success is dependent upon its ability to successfully market its products and services; grow revenue; control operating costs and expenses; meet its obligations; obtain additional capital when needed; and, ultimately, achieve profitable operations. COVID-19 In March 2020, the World Health Organization declared the outbreak of the new strain of the coronavirus (“COVID-19”) COVID-19 non-essential COVID-19 COVID-19 Going Concern Consideration The accompanying consolidated financial statements are prepared in accordance with generally accepted accounting principles applicable to a going concern, which contemplates the realization of assets and the satisfaction of liabilities in the normal course of business. Since inception, the Company has generated recurring losses which have resulted in an accumulated deficit of $123.3 million and $55.4 million as of December 31, 2021 and December 31, 2020, respectively, and expects to incur additional losses in the future. The Company is still in the growth stage of its business and expects to continue to make substantial investments in its business, including in the expansion of its product portfolio and research and development, sales and marketing teams, in addition to incurring additional costs as a result of being a public company. The Company believes the cash it obtained from the Business Combination and the private placement that occurred substantially concurrently with the consummation of the Business Combination (the “PIPE Investment”), are not sufficient to meet its working capital and capital expenditure requirements for a period of at least twelve months from the date of the issuance of these financial statements. As a result of the Company’s history of losses and negative cash flows from operations, and because its plans to obtain additional capital have not been completed at the time of the issuance of these consolidated financial statements, substantial doubt exists about the Company’s ability to continue as a going concern within one year after the date that these consolidated financial statements are issued. The Company expects to generate additional cash to fund its growth through future debt or equity transactions; however, there can be no assurance that the Company will be able to obtain other debt or equity financing on terms acceptable to the Company, if at all. Failure to secure additional funding may require the Company to modify, delay, or abandon some of its planned future expansion or development, or to otherwise enact operating cost reductions available to management, which could have a material adverse effect on the Company’s business, operating results, financial condition, and ability to achieve its intended business objectives. The Company has concluded that management’s plans do not alleviate substantial doubt about the Company’s ability to continue as a going concern. The consolidated financial statements do not include any adjustments relating to the recoverability and classification of recorded asset amounts or the amounts and classification of liabilities that might result from the outcome of this uncertainty.
ECP Environmental Growth Opportunities Corp
Description of Organization and Business Operations	Note 1—Description of Organization and Business Operations Fast Radius, Inc. (f/k/a ECP Environmental Growth Opportunities Corp.) (the “Company”) was formed as a Delaware corporation on October 29, 2020. The As of December 31, 2021, the Company had not commenced any operations. All activity through December 31, 2021 relates to the Company’s formation and the initial public offering (the “Initial Public Offering”), which is described below. The Company has selected December 31 as its fiscal year end. On February 11, 2021, the Company consummated its Initial Public Offering of 34,500,000 units (the “Units”), including 4,500,000 Units sold pursuant to the full exercise of the underwriters’ option to purchase additional Units to cover over-allotments. The Units were sold at a price of $10.00 per unit, generating gross proceeds to the Company of $345,000,000, which is described in Note 3. Simultaneously with the closing of the Initial Public Offering, the Company completed two private sales of an aggregate 6,266,667 warrants (the “Private Placement Warrants”) at a purchase price of $1.50 per Private Placement Warrant (the “Private Placements”), to ENNV Holdings, LLC (the “Sponsor”) and Goldman Sachs Asset Management, L.P. (“GSAM”), in its capacity as investment adviser on behalf of its clients (the “GSAM Client Accounts”), generating aggregate gross proceeds to the Company of $9,400,000, which is described in Note 3. Offering costs consist of legal, accounting, underwriting and other costs incurred through the consolidated balance sheet date that are directly related to the Initial Public Offering. Upon the completion of the Initial Public Offering, offering costs totaling $19,627,069 were allocated between the carrying value of Class A common stock ($18,876,326) and other expenses ($750,743) based on the fair value of warrant liabilities relative to the Initial Public Offering proceeds recognized in temporary equity. Following the closing of the Initial Public Offering on February 11, 2021, an amount of $345,000,000 ($10.00 per Unit) comprised of $338,100,000 of the proceeds from the Initial Public Offering, including $12,075,000 of the underwriters’ deferred discount, and $6,900,000 of the proceeds from the Private Placements were placed in a U.S.-based trust account at Morgan Stanley Smith Barney LLC maintained by American Stock Transfer & Trust Company, LLC, acting as trustee. Except with respect to interest earned on the funds in the trust account that may be released to the Company to pay its franchise and income taxes and expenses relating to the administration of the trust account, the proceeds from the Initial Public Offering and the Private Placements held in the trust account will not be released until the earliest of (a) the completion of the Company’s initial Business Combination, (b) the redemption of any public shares properly tendered in connection with a stockholder vote to amend the Company’s Amended and Restated Certificate of Incorporation (i) to modify the substance or timing of its obligation to redeem 100% of its public shares if the Company does not complete its initial Business Combination within 24 months from the closing of the Initial Public Offering or (ii) with respect to any other provisions relating to stockholders’ rights or pre-initial On July 18, 2021, the Company entered into an Agreement and Plan of Merger (as amended, the “Merger Agreement”) by and among the Company, Merger Sub, and Fast Radius Operations, Inc., a Delaware corporation (f/k/a Fast Radius, Inc.) (“Legacy Fast Radius”), pursuant to which Merger Sub agreed to merge with and into Legacy Fast Radius, with Legacy Fast Radius surviving such merger as a wholly owned subsidiary of the Company (the “Merger” and, together with the other transactions contemplated by the Merger Agreement, the “Business Combination”). At the closing of the Merger (the “Closing”), the Company was renamed “Fast Radius, Inc.” The Business Combination was completed on February 4, 2022. Subject to the terms of the Merger Agreement, the aggregate merger consideration with respect to all holders of Fast Radius securities outstanding immediately prior to the Closing, which will be issued in the form of shares or equity awards relating to shares of Class A common stock, will equal 75,000,000 shares of Class A common stock at a deemed value of $10.00 per share (the “Aggregate Merger Consideration”). The Aggregate Merger Consideration was issued to holders of Legacy Fast Radius securities at the Closing in accordance with the Merger Agreement, except that the issuance to holders of Legacy Fast Radius capital stock and Vested RSUs (as defined in the Merger Agreement) of a portion of the Aggregate Merger Consideration in an amount equal to 10,000,000 shares of Class A common stock (the “Fast Radius Earn Out Shares”) is subject to the satisfaction of certain price targets set forth in the Merger Agreement during the five-year any 20 trading days within any 30 consecutive trading day period within the Earn Out Period or (ii) the per share consideration received in connection with the occurrence of certain change of control events of the combined company following Closing specified in the Merger Agreement (any such event, an “Acquiror Sale”). In the event of an Acquiror Sale in which the per share consideration received is less than a price target set forth in the Merger Agreement that has not previously occurred, the applicable provisions of the Merger Agreement will terminate and no Fast Radius Earn Out Shares will be issuable thereunder with respect to such price target in connection with or following completion of such Acquiror Sale. The Fast Radius Earn Out Shares will be issuable in two equal tranches of 5,000,000 shares of Class A common stock at the time that the Class A common stock reaches a value, as calculated above, of $15.00 and $20.00 , respectively, and will be allocated among the applicable holders of Legacy Fast Radius capital stock and Vested RSUs on a pro rata basis in accordance with the Merger Agreement. On December 26, 2021, the Company, Merger Sub and Legacy Fast Radius entered into an amendment to the Merger Agreement to, among other things, require the affirmative vote of holders of a majority of the shares of Class A common stock then outstanding, voting separately as a single class, for the approval of the Amendment Proposal (as defined in the Merger Agreement). In connection with the Closing, the shares (the “Founder Shares”) of Class B common stock issued prior to the Company’s initial public offering that were held by the Sponsor, the Company’s independent directors at the time and GSAM automatically converted into shares of Class A common stock on a one-for-one % of the Converted Shares held by the Sponsor (the “Sponsor Earn Out Shares”) are subject to vesting upon the satisfaction of certain price targets set forth in the sponsor support agreement the Company entered into with the Sponsor and its independent directors concurrently with the execution of the Merger Agreement (the “Sponsor Support Agreement”) during the Earn Out Period, which price targets are based upon the (i) the daily volume-weighted average sale price of shares of Class A common stock quoted on NASDAQ, or the exchange on which the shares of Class A common stock are then traded, for In connection with the execution of the Merger Agreement, the Company entered into subscription agreements (collectively, the “Subscription Agreements”) with certain investors, including the Sponsor (collectively, the “PIPE Investors”), pursuant to which the PIPE Investors agreed to subscribe for and purchase, and the Company agreed to issue and sell to the PIPE Investors, an aggregate of 7,500,000 shares of Class A common stock (1,000,000 shares of which will be issued and sold to the Sponsor in its capacity as a PIPE Investor) for a purchase price of $10.00 per share, or an aggregate of $75,000,000, in a private placement (the “PIPE Investment”). The closing of the PIPE Investment occurred substantially concurrently with the consummation of the Business Combination. The shares of Class A common stock issued pursuant to the Subscription Agreements were not registered under the Securities Act and were issued in reliance upon the exemption provided under Section 4(a)(2) of the Securities Act. On January 20, 2022, ECP Environmental Growth Opportunities Corp. (“ENNV”), ENNV Holdings, LLC (the “Sponsor”) and Goldman Sachs Asset Management, L.P., in its capacity as investment adviser on behalf of its clients (“GSAM”), entered into a side letter (the “Side Letter”) to that certain forward purchase agreement, dated as of January 24, 2021, by and among ENNV, Sponsor and GSAM, as amended by that certain First Amendment to Forward Purchase Agreement dated as of January 31, 2021, and that certain Letter Agreement, dated as of July 18, 2021 (as so amended, the “Forward Purchase Agreement”). As previously disclosed, pursuant to the Forward Purchase Agreement, GSAM irrevocably consented to purchase twenty-five million dollars ($25,000,000) of units (“Forward Purchase Units”), each consisting of one share of Class A common stock, par value $0.0001 per share, of ENNV (“Class A Common Stock”) and one-quarter of one redeemable warrant (“Forward Purchase Warrant”), each whole redeemable warrant of which is exercisable to purchase one share of Class A Common Stock at an exercise price of $11.50 per share, in connection with the closing of ENNV’s previously announced Business Combination with Fast Radius, Inc. (the “Closing”). Pursuant to the Side Letter, if GSAM acquires any shares of Class A Common Stock (i) on or after the date of the Side Letter but prior to 4:00 p.m. New York City time on January 25, 2022 (the “Cutoff Time”) and does not exercise any right to redeem such shares in connection with ENNV’s redemption of Class A Common Stock in accordance with ENNV’s organizational documents in connection with the Closing (the “Redemption”) (and, if necessary to revoke any prior redemption elections made with respect to such shares, does so effectuate such revocation) or (ii) on or after the Cutoff Time but prior to February 1, 2022 and delivers evidence reasonably satisfactory to ENNV that (a) the stockholder from whom such shares were acquired had, prior to such acquisition, validly elected to redeem such shares in connection with the Redemption and (b) such stockholder or GSAM, as applicable, has, prior to Closing, validly revoked such election to redeem such shares in connection with the Redemption (such shares of Class A Common Stock described in clauses (i) and (ii), the “Eligible Shares”), and, in each case, does not transfer such Eligible Shares prior to the date of the Closing (the “Closing Date”), then such Eligible Shares shall be “Non-Redeemed Shares,” and the number of Forward Purchase Units GSAM is obligated to purchase under the Forward Purchase Agreement will be reduced by the number of Non-Redeemed Shares. Notwithstanding any such reduction in the number of Forward Purchase Units that GSAM is obligated to purchase under the Forward Purchase Agreement, upon consummation of the sale of such Forward Purchase Units, ENNV shall issue to GSAM a number of redeemable warrants, each of which is exercisable to purchase one share of Class A Common Stock at an exercise price of $11.50 per share, which warrants shall have the same terms as ENNV’s private placement warrants (the “Additional Warrants”), such that GSAM shall receive 625,000 Forward Purchase Warrants and Additional Warrants in the aggregate. Pursuant to the merger agreement, dated as of July 18, 2021 and amended on December 26, 2021 (the “Merger Agreement”), Fast Radius is required to provide its consent in order for ENNV to take certain actions under the Merger Agreement, including but not limited to, making amendments to the Forward Purchase Agreement. Fast Radius has provided its consent under the Merger Agreement for ENNV to enter into the Side Letter. On February 4, 2022, the Company completed its Business Combination with Legacy Fast Radius, resulting in Legacy Fast Radius surviving as a wholly owned subsidiary of the Company, and the Company being renamed “Fast Radius, Inc.” The underwriters of the ENNV IPO were entitled to a deferred fee of $0.35 per Unit, or $12,075,000 in the aggregate in connection with the Closing, irrespective of the amount of redemptions by the public stockholders. Approximately 91% of the Company’s outstanding shares were redeemed, as shareholders redeemed 31,512,573 Public Shares in connection with the Business Combination. As a result, approximately $ 315.1 underwriting fees. The Company has since paid the underwriters $1,257,146 of the remaining $5,028,585 of underwriting fees due upon the consummation of the Business Combination and deferred the remaining $3,771,439 to a later date. The Company’s management prior to the Business Combination had broad discretion with respect to the specific application of the net proceeds of its Initial Public Offering and the sale of Private Placement Warrants, although substantially all of the net proceeds were intended to be applied generally toward consummating a Business Combination. The Company’s initial Business Combination must have been with one or more operating businesses or assets that together had an aggregate fair market value equal to at of the net assets held in the Trust Account (as defined below) (excluding the deferred underwriting commissions and taxes payable on the interest earned on the Trust Account) at the time the Company signed a definitive agreement in connection with the initial Business Combination. However, the Company could only complete a Business Combination if the post-transaction company owns or acquire or more of the outstanding voting securities of the target or otherwise is not required to register as an investment company under the Investment Company Act 1940, as amended, or the Investment Company Act. Upon the closing of the Initial Public Offering, an amount equal to at least per Unit sold in the Initial Public Offering, including the proceeds of the Private Placement Warrants, were held in a trust account (“Trust Account”) with the American Stock Transfer & Trust Company acting as trustee and invested in money market funds meeting certain conditions under Rule 2a-7 The Company provided its holders of the public shares (the “Public Stockholders”) with the opportunity to redeem all or a portion of their Public Shares upon the completion of a Business Combination in connection with a stockholder meeting called to approve the Business Combination. The decision as to whether the Company would seek stockholder approval of a Business Combination was made by the Company, solely in its discretion. The Public Stockholders were entitled to redeem their Public Shares for a pro rata portion of the amount then in the Trust Account ( 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 tax obligations). The per-share Business Combination. The Company’s Sponsor, executive officers, directors and director nominees agreed not to propose an amendment to the Company’s Amended and Restated Certificate of Incorporation that would affect the substance or timing of the Company’s obligation to provide for the redemption of its Public Shares in connection with a Business Combination or to redeem 100% of its Public Shares if the Company does not complete a Business Combination, unless the Company provides the Public Stockholders with the opportunity to redeem their Class A common stock in conjunction with any such amendment. If the Company was unable to complete a Business Combination within 24 months from the closing of the Initial Public Offering (the “Combination Period”), the Company would (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 the Company to pay its taxes, if any (less up to interest to pay dissolution expenses) divided by the number of the then-outstanding Public Shares, which redemption will completely extinguish Public Stockholders’ rights as stockholders (including the right to receive further liquidation distributions, if any); and (iii) as promptly as reasonably possible following such redemption, subject to the approval of the remaining stockholders and the board of directors, liquidate and dissolve, subject in each case to the Company’s obligations under Delaware law to provide for claims of creditors and the requirements of other applicable law. There would be no redemption rights or liquidating distributions with respect to the Company’s warrants, which will expire worthless if the Company fails to complete a Business Combination within the Combination Period. In connection with the redemption of 100% of the Company’s outstanding Public Shares for a portion of the funds held in the Trust Account, each holder would receive a full pro rata portion of the amount then in the Trust Account, plus any pro rata interest earned on the funds held in the Trust Account and not previously released to the Company to pay the Company’s taxes (less up to $100,000 of interest to pay dissolution expenses). The Initial Stockholders agreed to waive their liquidation rights with respect to the Founder Shares if the Company failed to complete a Business Combination within the Combination Period. However, if the Initial Stockholders should 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 failed 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 did not complete a Business Combination within in the Combination Period and, in such event, such amounts would be included with the funds held in the Trust Account that would be available to fund the redemption of the Company’s Public Shares. Going Concern Consideration As of December 31, 2021, the Company had $82,234 of cash outside of the Trust Account and a working capital deficiency of $3,359,143. On July 30, 2021, the Company issued an unsecured promissory note (the “Note”) in the principal amount of $1,500,000 to an affiliate of the Sponsor, which may be drawn down by the Company from time to time upon written notice to the lender. The 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 Note shall not be repaid and all amounts owed under it will be forgiven. Upon the consummation of a Business Combination, the holder of the Note (or a permitted assignee) shall have the option, but not the obligation, to convert all or a portion of the unpaid principal balance of the Note into that number of warrants to purchase one share of Class A Common Stock, $0.0001 par value per share, of the Company (the “Working Capital Warrants”) equal to the principal amount of the Note so converted divided by $1.50. The terms of the Working Capital Warrants will be identical to the terms of the warrants issued by the Company to the Sponsor in a private placement that took place simultaneously with the Company’s Initial Public Offering. The Note is subject to customary events of default, the occurrence of which automatically trigger the unpaid principal balance of the Note and all other sums payable with regard to the Note becoming immediately due and payable. As of December 31, 2021, the $499,702 drawn against the Note ha d Since inception, Legacy Fast Radius has generated recurring losses which have resulted in an accumulated deficit of $123 million as of December 31, 2021. The Company expects to incur additional losses in the future as they expect to continue to make substantial investments in its business, including in the expansion of its product portfolio and in its research and development, sales and marketing teams, in addition to incurring additional costs as a result of being a public company. The Company believes the cash it obtained from the Business Combination and the private placement that occurred substantially concurrently with the consummation of the Business Combination, are not sufficient to meet its working capital and capital expenditure requirements for a period of at least twelve months from the date of these financial statements. As a result of the above, in connection with the Company’s assessment of going concern considerations in accordance with Accounting Standards Update (“ASU”) 2014-15, Risks and Uncertainties Management continues to evaluate the impact of the COVID-19

Summary of Significant Accounting Policies	Note 2 – Summary of Significant Accounting Policies Emerging Growth Company As an emerging growth company (“EGC”), the Jumpstart Our Business Startups Act (“JOBS Act”) allows the Company to delay adoption of new or revised accounting pronouncements applicable to public companies until such pronouncements are applicable to private companies. The Company has elected to use this extended transition period under the JOBS Act until such time the Company is no longer considered to be an EGC. The adoption dates discussed below reflect this election. Use of Estimates The preparation of the consolidated interim financial statements in conformity with U.S. GAAP requires management to make estimates, judgments and assumptions that affect the reported amounts of assets and liabilities, related disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses for the periods presented. The Company’s most significant estimates and judgements involve valuation of the Company’s debt and equity securities, including assumptions made in the fair value of warrants, derivatives, and stock-based compensation; the useful lives of fixed assets; and allowances for doubtful accounts. Although the Company regularly assesses these estimates, actual results could differ materially from these estimates. Changes in estimates are recorded in the period in which they become known. The Company bases its estimates on historical experience and various other assumptions that it believes to be reasonable under the circumstances. Actual results may differ from management’s estimates if these results differ from historical experience or other assumptions prove not to be substantially accurate, even if such assumptions are reasonable when made. Segment Information The Company operates and manages its business as one operating and reportable segment. The Company’s chief executive officer, who is the chief operating decision maker, reviews financial information on an aggregate basis for purposes of evaluating financial performance and allocating resources. The Company’s long-lived assets and customers are all substantially located in the United States. Cash and Cash Equivalents The Company considers all highly liquid investments with an original maturity of 90 days or less, or with the ability to redeem amounts on demand, to be cash and cash equivalents. The carrying amount of cash equivalents are reported at cost, which approximates their fair value. Accounts Receivable In evaluating the collectability of accounts receivable, the Company assesses a number of factors, including specific customers’ abilities to meet their financial obligations, the length of time a receivable is past due, and historical collection experience. If circumstances related to specific customers change, or economic conditions deteriorate such that the Company’s past collection experience is no longer relevant, its estimate of the recoverability of accounts receivable could be further reduced from the levels provided for in the consolidated financial statements. All accounts or portions thereof considered uncollectible are written off to the allowance for doubtful accounts in the period this information becomes known. Recoveries of trade receivables previously written off are recorded when received. The components of accounts receivable are as follows: December 31, 2021 December 31, 2020 Trade receivables $ 7,945,078 $ 5,451,252 Allowance for doubtful accounts (929,800 ) (404,755 ) Total accounts receivable $ 7,015,278 $ 5,046,497 The following table summarizes activity in the allowance for doubtful accounts : December 31, 2021 December 31, 2020 Balance at beginning of period $ (404,755 ) $ (190,205 ) Provision for uncollectible accounts (641,357 ) (710,882 ) Uncollectible accounts written off 116,312 496,332 Balance at end of period $ (929,800 ) $ (404,755 ) Significant Customers and Concentration of Credit Risks The Company is subject to credit risk primarily through its accounts receivable. Credit is extended to customers based on a credit review. The credit review considers each customer’s financial condition, including the customer’s established credit rating or the Company’s assessment of the customer’s creditworthiness based on their financial statements absent a credit rating, local industry practices, and business strategy. A credit limit and terms are established for each customer based on the outcome of this review. The Company performs on- Significant customers are those that represent more than 10% of the Company’s total revenue or accounts receivable. For the customers identified, revenue as a percentage of total revenue and accounts receivable as a percentage of net accounts receivable are as follows: December 31, 2021 December 31, 2020 Revenue for the years ended Customer A <10 % 21.6 % December 31, 2021 December 31, 2020 Accounts receivable Customer A < 1 % 24.2 % Customer B <10 % 13.3 % Inventories The Company’s inventories consist of raw materials, work-in-process, Inventories consisted of the following: December 31, 2021 December 31, 2020 Raw materials $ 432,461 $ 162,397 Work-in-process 16,310 107,770 Finished goods — 4,144 Total Inventories $ 448,771 $ 274,311 Cost is determined using the weighted-average method. The Company performs on-going Property and Equipment, net The Company’s property and equipment primarily consists of advanced manufacturing machinery, quality measurement equipment, other manufacturing infrastructure, office equipment and furniture, computer hardware, internally developed software, and networking equipment. Depreciation is computed using the straight-line method over the estimated useful life by asset category, or in the case of leasehold improvements, the shorter of the lease term including any renewal periods reasonably assured to be exercised at inception, or the estimated useful life of the asset category. Repairs and maintenance are expensed as incurred, while betterments and improvements that the Company determines extend the useful life or add functionality of property and equipment are capitalized. Property and equipment are depreciated over the estimated useful life of the asset categories as follows: Advanced Manufacturing Machinery & Quality Equipment 5 – 10 Years Computer & Office Hardware 5 Years Furniture & Fixtures 7 Years Internally Developed Software 3 – 5 years Leasehold Improvements Lesser of lease term The Company periodically reviews each asset category’s estimated useful life based upon actual experience and expected future utilization. A change in useful life is treated as a change in accounting estimate and is applied prospectively. The Company reviews the carrying amounts of property and equipment for potential impairment when events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. In evaluating recoverability, the Company groups assets and liabilities at the lowest level such that the identifiable cash flows relating to the group are largely independent of the cash flows of other assets and liabilities, which are each determined to be an asset group. The Company then compares the carrying amount of each asset group to the estimated undiscounted future cash flows attributable to the asset group. If the estimated undiscounted future cash flows for the asset group are not at least equal to the carrying amount, the Company estimates the fair value of the asset group and an impairment charge is recorded at the amount by which the carrying amount of the asset or asset group exceeds the fair value, if applicable. In addition, the remaining depreciation period for the impaired asset or asset group would be reassessed and, if necessary, revised. For the years ended December 31, 2021 and December 31, 2020, the Company did not recognize any impairment of its property and equipment. Refer to Note 4 for further information regarding property and equipment. Software applications developed for internal use are capitalized as internally developed software. Costs are capitalized when: (i) the preliminary project stage is completed (i.e., the application development stage) and (ii) it is probable that the software will be completed and used for its intended function. The Company also capitalizes costs related to specific upgrades and enhancements when it is probable the expenditures will result in additional functionality. Costs incurred for maintenance, minor upgrades and enhancements are expensed as incurred within general and administrative expense in the consolidated statements of net loss and comprehensive loss. Debt and Deferred Financing Fees Debt discounts are presented on the balance sheet as a direct deduction from the carrying amount of that related debt. Refer to Note 5 for further information regarding debt. Costs incurred in connection with the Company’s debt instruments consist principally of debt issuance costs and have been deferred and are being amortized over the terms of the related debt agreements using the effective interest method. Deferred financing fees are presented on the consolidated balance sheets as direct reductions to debt balances. Research and Development Costs Management invests resources to advance the development of its products and services for its customers, including the development of the cloud manufacturing software platform. Research and development costs represent costs incurred to support the advancement of new product platforms, consumables, and activities to enhance manufacturing capabilities. Research and development costs are comprised of prototype parts, design expense, employee-related personnel expense, and an allocated portion of overhead costs. Research and development costs are expensed as incurred. Net Loss Per Share The Company applies the two-class two-class two-class two-class Basic net loss per share attributable to stockholders is computed by dividing net loss attributable to the Company’s stockholders by the weighted-average number of common shares outstanding during the period without consideration of potentially dilutive Common Stock. Diluted net loss per share attributable to the Company’s stockholders reflects the potential dilution that could occur if securities or other contracts to issue Common Stock were exercised or converted into Common Stock or resulted in the issuance of Common Stock that then shared in the earnings of the Company unless inclusion of such shares would be anti-dilutive. For periods in which the Company reports net losses, diluted net loss per common share attributable to the Company’s stockholders is the same as basic net loss per common share attributable to the Company’s stockholders, because potentially dilutive common shares are not assumed to have been issued if their effect is anti-dilutive. Refer to Note 14 for further information regarding net loss per share. Advertising Costs Advertising costs are expensed as incurred. Advertising expenses consist primarily of media advertising costs, trade and customer marketing expenses, sales and marketing related personnel, and public relations expenses which aim to strengthen the leadership of the Company’s brand in key vertical markets. Advertising costs were approximately $7.9 million and $1.2 million for the years ended December 31, 2021 and 2020, respectively. All advertising expenses are recorded in Sales and marketing expense in the consolidated statements of net loss and comprehensive loss. Income Taxes Income taxes are accounted for under the asset and liability method. Deferred income tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases, and net operating loss and tax credit carry forwards. Deferred income tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred income tax assets and liabilities of a change in tax rates is recognized in the consolidated statements of net loss and comprehensive loss in the period that includes the enactment date. Deferred income tax assets are reduced by a valuation allowance when it is more likely than not that some portion of the deferred income tax assets will not be realized. The Company does not have any uncertain tax positions. A valuation allowance is provided unless it is more likely than not that the deferred tax asset will be realized. Assessing whether deferred tax assets are realizable requires significant judgement. In the determination of the appropriate valuation allowance, the Company considers future reversals of existing taxable temporary differences, the most recent projections of future business results, prior earnings history, carry back and carry forward periods, and prudent tax strategies. Assessments for the realization of deferred tax assets made at a given balance sheet date are subject to change in the future. Refer to Note 6 for further information regarding income taxes. Stock-Based Compensation—Options, RSUs and Warrants The Company accounts for stock-based compensation awards in accordance with Financial Accounting Standards Board (“FASB”) ASC 718, Compensation—Stock Compensation The Company’s stock-based awards are subject to service and/or performance-based vesting conditions. The Company recognizes compensation expenses for awards with only a service condition over the explicit service period using the straight-line method. For awards subject to a service and performance condition, compensation cost is recognized over the longer of the explicit, implicit, or derived period using the accelerated attribution method for cost allocation, as long as the performance condition is probable of achievement. At each reporting period, the Company evaluates the probability that its performance-based stock options will be earned and adjusts its previously recognized compensation expense as necessary. If the achievement of the respective performance metrics is not probable or the respective performance goals are not met, the Company reverses its previously recognized compensation expense. In accordance with ASC 718, excess tax benefits realized from the exercise of stock-based awards are classified as cash flows from operating activities. All excess tax benefits and tax deficiencies (including tax benefits of dividends on share-based payment awards) are recognized as income tax expense or benefit in the consolidated statements of net loss and comprehensive loss. The Company accounts for stock-based compensation awards issued to nonemployees for services, as prescribed by ASC 718, at either the fair value of the services rendered or the instruments issued in exchange for such services, whichever is more readily determinable using the measurement date guidelines enumerated in Accounting Standards Update (“ASU”) 2018-07, Improvements to Nonemployee Share-Based Payment Accounting 2018-07”). The Company has elected to account for forfeitures as they occur for both employee and nonemployee awards. Refer to Note 9 for further information regarding stock-based compensation. Fair Value Measurements Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. A hierarchy has been established for inputs used in measuring fair value that maximizes the use of observable inputs and minimizes the use of unobservable inputs by requiring that the most observable inputs be used when available. The Company has determined the estimated fair value of its financial instruments including stock-based awards, derivatives, and certain warrants, which are accounted for as liabilities, based on appropriate valuation methodologies; however, considerable judgment is required to develop these estimates. Accordingly, these estimated fair values are not necessarily indicative of the amounts the Company could realize in a current market exchange. The estimated fair values can be materially affected by using different assumptions or methodologies. The carrying amounts reported in the consolidated balance sheets for cash and cash equivalents represent cost, which approximates fair value. The carrying amounts reported in the consolidated balance sheets for accounts receivable, accounts payable, and accrued liabilities approximate fair value due to their short-term maturities. With the exception of the Company’s Related Party Convertible Notes, the fair value of the Company’s debt approximates their carrying values based on the variable nature of interest rates and current market rates available. The Company considers its debt to be a Level 3 measurement in the fair value hierarchy as significant judgment is involved to determine the fair value of embedded conversion features. Refer to Note 10 for further information regarding fair value. Redeemable Convertible Preferred Stock The Series Seed, Seed-1, A-1, A-2, A-3, Warrants The Company accounts for its warrants issued with other debt and equity instruments in accordance with ASC 480, Distinguishing Liabilities from Equity Treasury stock Treasury stock purchases are accounted for under the cost method whereby the entire cost of the acquired stock is recorded as treasury stock. Gains, and losses to the extent that gains were previously recorded, on the subsequent reissuance of shares are credited or charged to paid-in Revenue Recognition The Company determines revenue recognition through the following steps: • Identification of the contract, or contracts, with a customer; • Identification of the performance obligations in the contract; • Determination of the transaction price; • Allocation of the transaction price to the performance obligations in the contracts; and • Recognition of revenue when, or as, the Company satisfies a performance obligation The Company’s primary source of revenue is from product sales of manufactured parts. Fast Radius has contracts with customers where the transfer of control of the specified good varies from contract to contract, but predominantly occurs upon shipment. The Company does not act as an agent in any of its revenue arrangements. Fast Radius seldom offers assurance-type warranties in the ordinary course of business; however, when such warranties are included, they generally have a service life of four years beginning from the date of product purchase. In the event of a failure of products covered under the warranties, the Company may repair or replace the products at the customer’s discretion. As of December 31, 2021 and 2020, the Company has not incurred any warranty related costs related to products covered by this warranty. The Company also derives revenue from consulting agreements, in which the Company produces digital assets (CAD files) and physical assets (prototypes). For consulting contracts, the deliverables are combined to be one performance obligation within the context of the contract, and revenue is recognized over time or at a point-in- work-in- (cost-to-cost point-in-time Payments are generally due within a range of 30 to 90 days after the performance obligation has been satisfied. Revenue from consulting agreements is not material. The Company charges certain customers shipping and handling fees. These fees are recorded within revenue after transfer of control of the products to customers. Revenues related to shipping and handling were $0.8 million and $0.4 million in 2021 and 2020, respectively. When shipping and handling services are performed before transfer of control to customers, they are accounted for as a fulfillment cost and are included in cost of revenues as incurred. The Company will contract with third parties to produce certain components of a customer order. Costs paid in advance of production are recorded in current assets as prepaid production costs until control of the product is transferred to the customer. Under such outsourced manufacturing arrangements, the Company is the primary obligor to its customer. Contract liabilities consist of fees paid by the Company’s customers for which the associated performance obligations have not been satisfied and revenue has not been recognized based on the Company’s revenue recognition criteria described above. Contract assets are recorded when the Company has a right to consideration in exchange for goods or services that it has transferred to a customer but for which payment is conditional on more than just the passage of time. Given the nature of the Company’s contracts, the Company did not have any contract assets as of December 31, 2021 or 2020, respectively. Refer to Note 3 for further information regarding revenue.

Summary of Significant Accounting Policies	Note 2—Summary of Significant Accounting Policies Basis of Presentation The accompanying consolidated financial statements are presented in conformity with accounting principles generally accepted in the United States of America (“GAAP”) and pursuant to the rules and regulations of the SEC. Principles of Consolidation The consolidated financial statements include the accounts of the Company and its wholly owned subsidiary, Merger Sub, as of December 31, 2021. Merger Sub had no assets or liabilities as of December 31, 2021. All significant intercompany transactions and balances have been eliminated in consolidation. Emerging Growth Company The Company is an “emerging growth company,” as defined in Section 2(a) of the Securities Act, as modified by the Jumpstart Our Business Startups Act of 2012 (the “JOBS Act”), and it may take advantage of certain exemptions from various reporting requirements that are applicable to other public companies that are not emerging growth companies including, but not limited to, not being required to comply with the auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act of 2002, reduced disclosure obligations regarding executive compensation in its periodic reports and proxy statements, and exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and stockholder approval of any golden parachute payments not previously approved. Further, Section 102(b)(1) of the JOBS Act exempts emerging growth companies from being required to comply with new or revised financial accounting standards until private companies (that is, those that have not had a Securities Act registration statement declared effective or do not have a class of securities registered under the Exchange Act) are required to comply with the new or revised financial accounting standards. The JOBS Act provides that an emerging growth company can elect to opt out of the extended transition period and comply with the requirements that apply to non-emerging Use of Estimates The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of expenses during the reporting period. Making estimates requires management to exercise significant judgment. It is at least reasonably possible that the estimate of the effect of a condition, situation or set of circumstances that existed at the date of the consolidated financial statements, which management considered in formulating its estimate, could change in the near term due to one or more future confirming events. Accordingly, the actual results could differ significantly from those estimates. Cash and Cash Equivalents The Company considers all short-term investments with an original maturity of three months or less when purchased to be cash equivalents. The Company had $82,234 in cash and no cash equivalents, outside of the funds held in the Trust Account, as of December 31, 2021. Derivative Financial Instruments The Company accounts for the Warrants, Forward Purchase Agreement (as defined below), and Working Capital Loan conversion option (collectively, the “Instruments”) in accordance with the guidance contained in ASC 815-40 re-measurement Marketable Securities Held in Trust Account At December 31, 2021, the assets held in the Trust Account were invested in money market funds. Class A Common Stock Subject to Possible Redemption The Company accounts for its Class A common stock subject to possible redemption in accordance with the guidance in ASC Topic 480 “Distinguishing Liabilities from Equity.” Common stock subject to mandatory redemption is classified as a liability instrument and is measured at fair value. Conditionally redeemable common stock (including common stock that features redemption rights that is either within the control of the holder or subject to redemption upon the occurrence of uncertain events not solely within the Company’s control) is classified as temporary equity. At all other times, common stock is classified as shareholders’ equity. The Company’s Class A common stock features certain redemption rights that are considered to be outside of the Company’s control and subject to occurrence of uncertain future events. Accordingly, at December 31, 2021, 34,500,000 shares of Class A common stock subject to possible redemption are presented as temporary equity outside of the shareholders’ equity section of the Company’s balance sheets. The Company recognizes changes in redemption value immediately as they occur and adjusts the carrying value of redeemable common stock to equal the redemption value at the end of each reporting period. Increases or decreases in the carrying amount of redeemable common stock are affected by charges against additional paid in capital and accumulated deficit. For the year ended December 31, 2021, the Company recorded a remeasurement of Class A common stock to the redemption value in the amount of $32,015,603. The Class A common stock subject to possible redemption reflected in the consolidated balance sheet at December 31, 2021 is reconciled in the following table: Gross proceeds $ 345,000,000 Less: Proceeds allocated to public warrants (12,880,575 ) Deferred underwriting fees (12,075,000 ) Other offering costs (7,060,028 ) Plus: Total remeasurement of carrying value to redemption value 32,015,603 Class A common stock subject to possible redemption $ 345,000,000 Concentrations of Credit Risk Financial instruments that potentially subject the Company to concentration of credit risk consist of a cash account in a financial institution which, at times may exceed the Federal Deposit Insurance Corporation (FDIC) coverage of $250,000. At December 31, 2021, the Company had not experienced losses on this account and management believes the Company is not exposed to significant risks on such account. Financial Instruments Except for the Warrant and Forward Purchase Agreement Liabilities as described above, the fair value of the Company’s assets and liabilities, which qualify as financial instruments under the Financial Accounting Standards Board (the “FASB”) ASC 820, “Fair Value Measurements and Disclosures,” approximates the carrying amounts represented in the consolidated balance sheets. Fair Value Measurements Fair value is defined as the price that would be received for sale of an asset or paid for transfer of a liability, in an orderly transaction between market participants at the measurement date. GAAP establishes a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). These tiers include: • Level 1, defined as observable inputs such as quoted prices for identical instruments in active markets; • Level 2, defined as inputs other than quoted prices in active markets that are either directly or indirectly observable such as quoted prices for similar instruments in active markets or quoted prices for identical or similar instruments in markets that are not active; and • Level 3, defined as unobservable inputs in which little or no market data exists, therefore requiring an entity to develop its own assumptions, such as valuations derived from valuation techniques in which one or more significant inputs or significant value drivers are unobservable. In some circumstances, the inputs used to measure fair value might be categorized within different levels of the fair value hierarchy. In those instances, the fair value measurement is categorized in its entirety in the fair value hierarchy based on the lowest level input that is significant to the fair value measurement. As of December 31, 2021, the carrying values of cash, prepaid expenses, other current assets, accounts payable and accrued expenses approximate their fair values due to the short-term nature of the instruments. The Company’s portfolio of marketable securities held in the Trust Account is comprised of money market funds. The fair values of Forward Purchase Agreement and Private Placement Warrants have been estimated using the trading price of the Public Warrants. Public Warrants are valued based on quoted price in active markets. See Note 5 and 6 for further discussion of the pertinent terms of the Warrants and Forward Purchase Agreement and Note 8 for further discussion of the methodology used to determine the value of the Warrants and Forward Purchase Agreement. Offering Costs Offering costs consist of legal, accounting, underwriting and other costs incurred through the consolidated balance sheet date that are directly related to the Initial Public Offering. Upon the completion of the Initial Public Offering in February 2021, the offering costs were allocated using the relative fair values of the company common stock and its Warrants. The costs allocated to Warrants were recognized in other expenses and those related to the Company’s common stock were charged to temporary equity. Net Income Per Share of Common Stock Net income per share of common stock is computed by dividing net income (loss) by the weighted average number of shares issued and outstanding during the period. The Company has not considered the effect of their Forward Purchase Agreement, warrants sold in the Initial Public Offering, private placement to purchase Class A common stock, and Working Capital Loan warrants in the calculation of diluted income per share, since the instruments are not dilutive. At December 31, 2021, the Company did not have any dilutive securities and other contracts that could, potentially, be exercised or converted into common stock and then share in the earnings of the Company under the treasury stock method. As a result, diluted income per share is the same as basic income per share for the periods presented. The Company has two classes of shares, which are referred to as Class A common stock and Class B common stock (the “Founder Shares”). Earnings are shared pro rata between the two classes of shares as long as an Initial Business Combination is consummated. Remeasurement associated with the redeemable shares of Class A common stock is excluded from earnings per share as the redemption value approximates fair value. A reconciliation of the earnings per share is below: For the Year December 31, 2021 For The Period Numerator: Earnings allocable to Redeemable Class A Common Stock Net Earnings allocable to Redeemable Class A Common Stock $ 4,660,201 $ — Denominator: Weighted Average Share Outstanding, Redeemable Class A Common Stock Basic and diluted weighted average shares outstanding, Redeemable Class A 30,624,658 — Basic and diluted net earnings per share, Redeemable Class A $ 0.15 $ — For the Year December 31, 2021 For The Period Non-Redeemable Numerator: Net Income allocable to Non-Redeemable Net Income allocable to Non-Redeemable $ 1,293,249 $ (20 ) Denominator: Weighted Average Non-Redeemable Basic and diluted weighted average shares outstanding, Non-Redeemable 8,498,630 7,500,000 Basic and diluted net earnings per share, Non-Redeemable $ 0.15 $ 0.00 Income Taxes The Company complies with the accounting and reporting requirements of ASC Topic 740, “Income Taxes,” which requires an asset and liability approach to financial accounting and reporting for income taxes. Deferred income tax assets and liabilities are computed for differences between the financial statement and tax bases of assets and liabilities that will result in future taxable or deductible amounts, based on enacted tax laws and rates applicable to the periods in which the differences are expected to affect taxable income. Valuation allowances are established, when necessary, to reduce deferred tax assets to the amount expected to be realized. ASC Topic 740 prescribes a recognition threshold and a measurement attribute for the financial statement recognition and measurement of tax positions taken or expected to be taken in a tax return. For those benefits to be recognized, a tax position must be more-likely-than-not to be sustained upon examination by taxing authorities. The Company’s management determined that the United States is the Company’s only major tax jurisdiction. The Company recognizes accrued interest and penalties related to unrecognized tax benefits as income tax expense. There were no unrecognized tax benefits and no amounts accrued for interest and penalties as of December 31, 2021. The Company is currently not aware of any issues under review that could result in significant payments, accruals or material deviation from its position. The Company is subject to income tax examinations by major taxing authorities since inception. Recent Accounting Pronouncements In August 2020, the FASB issued ASU 2020-06, 470-20) 815-40) 2020-06”) 2020-06 2020-06 if-converted 2020-06 2020-06 Management does not believe that any recently issued, but not yet effective, accounting pronouncements, if currently adopted, would have a material effect on the Company’s consolidated financial statements.

Revenue from Contract with Customer [Abstract]
Revenue	NOTE 3 - REVENUES The Company charges certain customers shipping and handling fees. These fees are recorded within revenue when incurred after transfer of control of the products to customers. Revenues related to shipping and handling fees were $0.8 million and $0.4 million for the years ended December 31, 2021 and 2020, respectively. When shipping and handling services are performed before transfer of control to customers, they are accounted for as a fulfillment cost and are included in cost of revenues when incurred. The Company will contract with third parties to produce certain components of a customer order. Costs paid in advance of production are recorded in current assets as prepaid production costs until control of the product is transferred to the customer. Under such outsourced manufacturing arrangements, the Company is the primary obligor to its customer. Contract assets are recorded when the Company has a right to consideration in exchange for goods or services that it has transferred to a customer but for which payment is conditional on more than just the passage of time. Contract liabilities consist of fees paid by the Company’s customers for which the associated performance obligations have not been satisfied and revenue has not been recognized based on the Company’s revenue recognition criteria. The Company did not have any contract assets as of December 31, 2021 or 2020, respectively. Deferred revenue (contract liabilities) is recognized when a customer pays consideration before the Company transfers goods or provide services and was $5 thousand as of December 31, 2020. There were no contract liabilities as of December 31, 2021. During the year ended December 31, 2021, the amount of revenue recognized that was included in deferred revenue as of December 31, 2020 was not significant.

All advances under the agreement are collateralized by the specific equipment financed in accordance with the agreement terms. On December 31, 2018, the Company financed the acquisition of advanced manufacturing equipment and machinery in the amount of $1.1 million. The loan required 36 monthly payments of principal and interest, with a maturity date of November 1, 2021. The loan did not have a stated interest rate; therefore, the Company calculated the imputed interest rate using the Yield-to-Maturity A-3 one-third one- acceleration upon events of default that are outlined within the agreement. On November 1, 2021, the ATEL loan was paid in full, including the outstanding interest and principal balance. 2018 SVB Loan On October 12, 2018, the Company entered into a term loan agreement with Silicon Valley Bank (“SVB”) for $3.0 million (hereafter referred to as the “2018 SVB loan”). The term loan required monthly payments of principal and interest, with all remaining principal and interest due on September 1, 2022. The term loan had an interest rate of prime rate + 1.25%. The loan was substantially collateralized by personal property and equity, as guaranteed by the Company. The term loan agreement did not contain financial covenants. In conjunction with the term loan, the Company issued warrants for the purchase of up to 46,636 shares of Common Stock at an exercise price of $0.45 per share. The warrants were recorded as a discount to the term note. Refer to Note 8 for information regarding redeemable warrants. On February 19, 2020, the Company extinguished the 2018 SVB loan by repaying the outstanding interest and principal balance. The Company also expensed the remainder of the deferred financing fees associated with the loan. 2020 MFS Loan On November 4, 2020, the Company entered into a secured loan agreement with Manufacturers Financing Services (“MFS”) for $0.4 million to finance the purchase of printing equipment. The loan required a 10% down payment at the time of origination, with 60 monthly payments of $7 thousand inclusive of principal and interest to be paid through December 1, 2025. The imputed interest rate for the periods ended December 31, 2021 and 2020 was approximately 3.4% and 4.1%, respectively. The loan agreement does not contain any financial covenants. The loan is substantially secured by the equipment serving as collateral. The outstanding balance of the loan was $315 thousand as of December 31, 2021. 2020 SVB Loan On December 29, 2020, the Company entered into a term loan credit agreement with SVB with a maximum credit extension of $6.5 million (“2020 SVB loan”). On March 12, 2021, the agreement was amended to increase the maximum credit extension to $10.0 million. The credit agreement defines two tranches of “availability” for advances. The first tranche must be drawn by May 31, 2021 and the second tranche must be drawn by September 30, 2021. The agreement requires monthly interest payments of 4.9% on the outstanding principal and monthly principal payments of $277.8 thousand beginning January 1, 2022. The term of the loan is the earlier to occur of the 36th month after the last tranche of funding and no later than December 1, 2024. The interest rate on the term loan is the greater of (a) the prime rate + 1.0%, or (b) 2.25%. In connection with acquiring the financing from the 2020 SVB loan, the Company issued warrants for the purchase of 26,115 shares of Common Stock at an exercise price of $1.81 per share. On March 12, 2021, the Company issued 26,115 additional warrants for the purchase of common shares at an exercise price of $13.49 per share. On May 25, 2021, the Company issued 26,115 additional warrants for the purchase of common shares at an exercise price of $13.49 per share. The warrants were determined to be liability classified and were recorded at their issuance date fair value as a discount to the loan. See Note 8 for further discussion on redeemable warrants. On May 25, 2021, the Company drew the full availability of the loan. The outstanding balance of the loan as of December 31, 2021 was $10.0 million. 2021 SVB Loan On September 10, 2021, the Company entered into a term loan credit agreement with SVB with a maximum credit extension of $20.0 million. The first $10.0 million of the loan can be drawn upon immediately, and the remaining $10.0 million can only be drawn upon to the amount of other additional financing that the Company receives. The company will make interest-only payments until the term loan’s maturity date, which is the earlier of a merger with a special purpose acquisition company (“SPAC”) or March 10, 2022. The interest rate on the term loan is the prime rate + 6.0%. On September 10, 2021, the Company drew the initial $10.0 million and an additional $3.0 million when the Drive Capital convertible debt was issued. The Company subsequently drew the remaining $7.0 million on October 26, 2021 when the ECP convertible debt was issued. As of November 8, 2021, the full $20 million has been drawn on the loan.

The Company’s deferred income tax assets and liabilities at December 31, 2021 and 2020 were comprised of the following: Years Ended December 31, 2021 2020 Deferred Tax Assets: Allowance for doubtful accounts $ 273,692 $ 110,381 Accruals and reserves 4,448,488 733,051 Disallowed interest carryforwards 1,332,346 — Net operating loss and other carryforwards 24,171,779 12,418,254 Stock based compensation 505,580 377,514 Other, net 40,507 16,364 Deferred tax assets before valuation allowance $ 30,772,392 $ 13,655,564 Valuation Allowance (30,739,829 ) (13,591,637 ) Total Deferred Tax Assets, net of valuation allowance 32,563 63,927 Deferred Tax Liabilities: Depreciation 32,563 63,927 Total Deferred Tax Liabilities 32,563 $ 63,927 Net Deferred Tax Assets (Liabilities) $ — $ — A valuation allowance is required to be established when it is more likely than not that all or a portion of a deferred tax asset will not be realized. Realization of deferred tax assets is dependent upon future earnings, the timing and amount of which are uncertain. A full review of all positive and negative evidence needs to be considered, including the Company’s current and past performance, the market environments in which the Company operates, the utilization of past tax credits, length of carry back and carry forward periods, as well as tax planning strategies that might be implemented. Management believes that, based on a number of factors, it is more likely than not, that all of the deferred tax assets may not be realized; and accordingly, as of December 31, 2021 and 2020, the Company has provided a full valuation allowance against its net deferred tax assets. On a gross basis, the Company has Federal net operating loss carry forwards of $89.8 million and $43.9 million as of December 31, 2021 and December 31, 2020, respectively, of which $1.0 million will expire in 2027 and the remainder of which may be carried forward indefinitely. The Company also has State gross net operating loss carry forwards of $79.3 million and $50.1 million as of December 31, 2021 and December 31, 2020, respectively, in various state jurisdictions which begin to expire in 2030. A full valuation allowance has been established for these net operating loss carry forwards as of December 31, 2021 and December 31, 2020. The increase in the valuation allowance in 2021 was due to an increase in the Federal valuation allowance of $14.0 million and an increase to State valuation allowances of $3.2 million. The following is a rollforward of the Company’s valuation allowances for the years ended December 31, 2021 and 2020, respectively: Valuation allowance as of January 1, 2020 $ 7,831,390 Adjustments to the valuation allowance 5,760,247 Valuation allowances as of December 31, 2020 13,591,637 Adjustments to the valuation allowance 17,148,192 Valuation allowance as of December 31, 2021 $ 30,739,829 The Company has no unrecognized tax benefits as of December 31, 2021 and December 31, 2020.

Income Taxes	Note 9—Income Taxes The Company’s taxable income primarily consists of interest income on the Trust Account, less any franchise taxes. The Company’s formation costs are generally considered start-up costs and are not currently deductible. Significant components of the Company’s deferred tax assets and liabilities as of December 31, 2021 are as follows: Deferred tax assets Organization costs $ 696,819 Net Operating Loss Carryforward 30,505 Total deferred tax asset . . . . . . . . . . . . . . . . . . . . . . . . . .. 727,325 Valuation allowance . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

The federal net operating losses can be carried forward indefinitely. In assessing the realization of the deferred tax assets, management considers whether it is more likely than not that some portion of all of the deferred tax assets will not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which temporary differences representing net future deductible amounts become deductible. Management considers the scheduled reversal of deferred tax liabilities, projected future taxable income and tax planning strategies in making this assessment. After consideration of all the information available, management believes that significant uncertainty exists with respect to the future realization of deferred tax assets and therefore established a full valuation allowance of $727,325 as of December 31, 2021. The income tax provision (benefit) for the year ended December 31, 2021 consists of the following: Deferred expense (benefit) Federal . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . $ (727,325 ) Valuation allowance . . . . . . . . . . . . . . . . . . . . . . . . . . . . . $ 727,325 Total income expense (benefit) — Income taxes during the year ended December 31, 2021 differ from the expected U.S federal income tax rate of pre-tax earnings from continuing operations due to the impact of nondeductible expenses and valuation allowances on deferred tax assets. The following permanent items impact the rate: changes in fair value of warrant liabilities, non-deductible transaction costs, post-LOI merger costs, offering costs allocated to derivate liabilities, and changes in fair value of forward purchasing agreement.

However, the exercise price of the underlying warrants was greater than the warrant fair value as of December 31, 2021, and when the Note was drawn on. The Company believes that the likelihood of the Sponsor’s exercise of the option to convert the Note to warrants is de minimis. As a result, the Company recorded zero liability related to the conversion option. The terms of the Working Capital Warrants will be identical to the terms of the warrants issued by the Company to the Sponsor in a private placement that took place simultaneously with the Company’s Initial Public Offering. The Note is subject to customary events of default, the occurrence of which automatically trigger the unpaid principal balance of the Note and all other sums payable with regard to the Note becoming immediately due and payable. As of December 31, 2021, there was a balance of $499,702 under this loan. Administrative Services Agreement The Company entered into an Administrative Services Agreement pursuant to which the Company will pay an affiliate of our Sponsor a total of $10,000 per month, until the earlier of the completion of the initial Business Combination and the liquidation of the trust assets, for office space, utilities, administrative and support services. Upon completion of the initial Business Combination or liquidation, the Company will cease paying these monthly fees. For the year ended December 31, 2021, the Company expensed $107,143 in monthly administrative support services. Promissory Note - Related Party On January 26, 2021, the Company entered into a promissory note pursuant to which Energy Capital Partners Management, LP (“ECP”) agreed to loan the Company up to $300,000 to be used for a portion of the expenses of the Initial Public Offering. The promissory note was repaid in full upon the Initial Public Offering. ECP Holdings Note On October 26, 2021, Energy Capital Partners Holdings, LP (“ECP Holdings”), an affiliate of the Sponsor, entered into a note purchase agreement with Legacy Fast Radius, pursuant to which ECP Holdings purchased a convertible promissory note (the “ECP Note”) in an aggregate principal amount of $7.0 million from Fast Radius. The ECP Note matures on October 26, 2023 (the “Maturity Date”) and interest on the unpaid principal amount under the ECP Note accrues at a rate of six percent (6%) per annum. The aggregate principal amount of the ECP Note may not be paid prior to the maturity date without the written consent of ECP Holdings. Upon the occurrence and during the continuance of an event of default, ECP Holdings may declare all unpaid principal, together with any then unpaid and accrued interest and other amounts payable under the ECP Note, immediately due and payable. If Fast Radius consummates any transaction or series of related transactions involving (i) the sale, lease, exclusive license, or other disposition of all or substantially all of its assets; (ii) any merger or consolidation of Fast Radius into or with another person or entity (other than a merger or consolidation effected exclusively to change its domicile), (iii) any other corporate reorganization, in which the stockholders of Fast Radius in their capacity as such immediately prior to such merger, consolidation or reorganization, own less than a majority of Fast Radius’ (or the surviving or successor entity’s) outstanding voting power immediately after such merger, consolidation or reorganization; or (iv) any sale or other transfer by the stockholders of Fast Radius of shares representing at least a majority of Fast Radius’ then-total outstanding combined voting power (such transaction or series of related transactions, an “Acquisition”) before (x) Fast Radius issues and sells preferred equity in a transaction or series of transactions for aggregate gross proceeds of at least $40.0 million (excluding all proceeds from the incurrence of indebtedness that is converted into such equity, or otherwise cancelled in consideration for the issuance of such equity) with the principal purpose of raising capital (a “Qualified Financing”) or (y) the repayment in full or conversion of the ECP Note, then ECP Holdings will be entitled to a cash payment equal to the greater of (A) two times the outstanding principal amount of the ECP Note plus all accrued and unpaid interest and (B) the amount that would be received in such Acquisition transaction if the outstanding principal amount of the ECP Note, plus all accrued and unpaid interest, were converted into Fast Radius common equity immediately prior to the closing of such Acquisition at the applicable conversion price. If a Qualified Financing occurs on or before the Maturity Date, then the outstanding principal amount of the ECP Note, and all accrued and unpaid interest, will automatically convert into shares of Fast Radius preferred equity on the same terms as those issued in such Qualified Financing at the applicable conversion price. In the case of a business combination transaction between Fast Radius and any special purpose acquisition company (including, for the avoidance of doubt, the Business Combination) with the purpose of taking Fast Radius public without going through the traditional initial public offering process (a “SPAC Transaction”) that occurs prior to the consummation of a Qualified Financing or the Maturity Date, the outstanding principal amount of the ECP Note, together with all accrued and unpaid interest, shall be automatically converted into Fast Radius common stock immediately prior to the consummation of such SPAC Transaction at the applicable conversion price. If no Qualified Financing or SPAC Transaction occurs on or before the Maturity Date, then the outstanding principal amount of the ECP Note, and all accrued and unpaid interest, shall be convertible at the option of ECP Holdings into Fast Radius common stock at the applicable conversion price within 90 days after the Maturity Date. In addition, if, prior to the repayment in full or conversion of the ECP Note, Fast Radius consummates an equity financing that does not qualify as a Qualified Financing (a “Non-Qualified The conversion price under the ECP Note will determined as follows: (i) if a Qualified Financing, Non-Qualified Non-Qualified Non-Qualified Non-Qualified Non-Qualified

Commitments & Contingencies	Note 5—Commitments & Contingencies Registration and Stockholder Rights The holders of the Founder Shares, Private Placement Warrants, and Working Capital Warrants that may be issued upon conversion of the amounts due under the Note at the time the Company consummates a Business Combination (and any Class A common stock issuable upon the exercise of the Private Placement Warrants and warrants that may be issued upon conversion of Working Capital Loans) will be entitled to registration rights pursuant to a registration and stockholder rights agreement to be signed prior to or on the effective date of the Initial Public Offering. The holders of these securities are entitled to make up to three demands, excluding short form demands, that the Company registers such securities. In addition, the holders have certain “piggy-back” registration rights with respect to registration statements filed subsequent to the completion of the initial Business Combination. The Company will bear the expenses incurred in connection with the filing of any such registration statements. In the event of any delay in filing and/or effectiveness of the registration statement required pursuant to the registration and stockholder rights agreement, or after the effective date, such registration statement ceases for any reason to remain continuously effective (each, a “Registration Default”), the holders will be entitled to payments from the Company equal to 2% of the purchase price on the occurrence of each registration default and 2% per month that such registration default continues to exist, as more fully described in the registration and stockholder rights agreement. Underwriting Agreement The Company granted the underwriters an option to cover over-allotments and for market stabilization purposes. The over-allotment option entitled the underwriters to purchase on a pro rata basis up to 4,500,000 additional Units at the Initial Public Offering price, less the underwriting discounts and commissions. On the date of th e Initial Public Offering, the underwriters exercised the over-allotment option in full, purchasing 4,500,000 Units. The underwriters are entitled to a deferred fee of $0.35 per Unit, or $12,075,000 in the aggregate. The deferred fee will be waived by the underwriters in the event that the Company does not complete a Business Combination, subject to the terms of the underwriting agreement. Forward Purchase Agreement On January 24, 2021, the Company entered into a Forward Purchase Agreement with GSAM, in its capacity as investment adviser on behalf of the GSAM Client Accounts, as amended by the First Amendment to Forward Purchase Agreement, dated as of January 31, 2021 (as so amended, the “Forward Purchase Agreement”), pursuant to which the GSAM Client Accounts committed to purchase an aggregate of up to 5,000,000 forward purchase units (the “Forward Purchase Units”), consisting of one share of the Company’s Class A common stock (the “Forward Purchase Shares”) and one Class A common stock temporary equity in the amount of $1,508,461 during the year ended December ha (as described in Note 3 above) purchased in the Initial Public Offering and, as such, the associated costs were allocated between the Company’s common stock and Public Warrants contained in the Units based on the respective fair values. Costs allocated to the Company’s stock were deferred and recorded as a reduction to temporary equity, while the costs allocated to Public Warrants were expensed. Concurrently with the execution of the Merger Agreement on July 18, 2021, the Company, the Sponsor and GSAM, in its capacity as investment adviser on behalf of the GSAM Client Accounts, entered into a side letter to the Forward Purchase Agreement, pursuant to which GSAM irrevocably consented to purchase from the Company, and the Company agreed to issue and sell to GSAM, 2,500,000 Forward Purchase Units at a price of $10.00 per Forward Purchase Unit, or an aggregate of $25,000,000, in a private placement to be consummated substantially concurrently with the consummation of the Business Combination.

No fractional Public Warrants will be issued upon separation of the Units and only whole Public Warrants will trade. The Public Warrants will become exercisable on the later of (a) 30 days after the completion of a Business Combination or (b) 12 months from the closing of the Initial Public Offering; provided in each case that the Company has an effective registration statement under the Securities Act covering the shares of Class A common stock issuable upon exercise of the Public Warrants and a current prospectus relating to them is available and such shares are registered, qualified or exempt from registration under the securities, or blue sky, laws of the state of residence of the holder (or the Company permit holders to exercise their warrants on a cashless basis under certain circumstances). The Company has agreed that as soon as practicable, but in no event later than 20 business days after the closing of the initial Business Combination, the Company will use commercially reasonable efforts to file with the SEC and have an effective registration statement covering the shares of Class A common stock issuable upon exercise of the warrants and to maintain a current prospectus relating to those shares of Class A common stock until the warrants expire or are redeemed, as specified in the warrant agreement. If a registration statement covering the shares of Class A common stock issuable upon exercise of the warrants is not effective by the 60th day after 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 will have failed to maintain an effective registration statement, exercise warrants on a “cashless basis” in accordance with Section 3(a)(9) of the Securities Act or another exemption. Notwithstanding the above, if the shares of Class A common stock are at the time of any exercise of a warrant not listed on a national securities exchange such that they satisfy the definition of a “covered security” under Section 18(b)(1) of the Securities Act, the Company may, at its option, require holders of Public Warrants who exercise their warrants to do so on a “cashless basis” and, in the event the Company so elects, the Company will not be required to file or maintain in effect a registration statement, and in the event the Company does not so elect, it will use commercially reasonable efforts to register or qualify the shares under applicable blue sky laws to the extent an exemption is not available. The warrants have an exercise price of $11.50 per share, subject to adjustments, and will expire five years after the completion of a Business Combination or earlier upon redemption or liquidation. In addition, if (x) the Company issues additional shares of Class A common stock or equity-linked securities for capital raising purposes in connection with the closing of the initial Business Combination at an issue price or effective issue price of less than $9.20 per common share (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 Sponsor or its affiliates, without taking into account any Founder Shares held by the Sponsor or such affiliates, as applicable, prior to such issuance) (the “Newly Issued Price”), (y) the aggregate gross proceeds from such issuances represent more th an 60% of the total equity proceeds, and interest thereon, available for the funding of the initial Business Combination on the date of the consummation of the initial Business Combination (net of redemptions), and (z) the volume weighted average trading price of the shares of Class A common stock during the 20 trading day period starting on the trading day prior to the day on which the Company consummates its initial Business Combination (such price, the “Market Value”) is below $9.20 per share, the exercise price of the warrants will be adjusted (to the nearest cent) to be equal to 115% of the higher of the Market Value and the Newly Issued Price, and the $18.00 per share redemption trigger price described under “Redemption of warrants when the price per share of Class A common stock equals or exceeds $18.00” will be adjusted (to the nearest cent) to be equal to 180% of the higher of the Market Value and the Newly Issued Price, and the $10.00 per share redemption trigger price described under the caption “Redemption of warrants when the price per share of Class A common stock equals or exceeds $10.00” will be adjusted (to the nearest cent) to be equal to the higher of the Market Value and the Newly Issued Price.

The “fair market value” shall mean the volume-weighted average price of the Class A 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. In no event will the Company be required to net cash settle any warrant. If the Company is unable to complete a Business Combination within the Combination Period and the Company liquidates the funds held in the Trust Account, holders of warrants will not receive any of such funds with respect to their warrants, nor will they receive any distribution from the Company’s assets held outside of the Trust Account with the respect to such warrants. Accordingly, the warrants may expire worthless. Forward Purchase Warrants have the same terms as the Public Warrants, except the Forward Purchase Warrants will be subject to transfer restrictions and certain registration rights. The company accounts for the Public Warrants, Private Placement Warrants and Forward Purchase Agreement in accordance with the guidance contained in ASC 815-40.

Stock Based Compensation

Share-based Payment Arrangement [Abstract]
Stock Based Compensation	NOTE 9 – STOCK BASED COMPENSATION Stock Options On December 4, 2017, the Company’s Board of Directors adopted its 2017 Incentive Plan which subsequently was amended and restated on July 29, 2020 (the “Plan”). The Plan was entered into with the objective of attracting and retaining key personnel, providing for additional performance incentives, and promoting the success of the Company by increasing the efforts of participants. The Plan seeks to achieve this purpose by providing for awards in the form of stock options (“options”) and RSUs to officers, employees, consultants, and directors of the Company. Pursuant to the Plan, the Company has issued the following stock-based payment awards to employees and nonemployees in exchange for services provided to the Company, (i) options to the Company’s founders, including options early exercised through a promissory note, (ii) stock options and RSUs to various employees and former employees, and (iii) options and warrants issued to various nonemployee consultants (collectively, the “Awards”). The underlying Awards pursuant to the Plan are administered by the Compensation and Management Development Committee of the Board of Directors. 12,258,817 shares are reserved and available for grant and issuance pursuant to the Plan as of the date of adoption of the amended Plan. Stock-based compensation expense during the years ended December 31, 2021 and 2020, was $0.9 million and $1.0 million respectively. No income tax benefit was recognized in the consolidated statements of net loss and comprehensive loss and an immaterial amount of compensation was capitalized during 2021. Stock-based compensation expense was recorded in the following financial statement lines within the consolidated statements of net loss and comprehensive loss: December 31, 2021 December 31, 2020 Cost of Revenues $ 13,402 $ 14,383 General and Administrative $ 680,609 $ 825,664 Selling and Marketing $ 79,695 $ 104,985 Research & Development $ 81,690 $ 47,048 In 2018, founders early exercised approximately 7.7 million stock options through execution of partial-recourse promissory notes. The options had an exercise price of $0.28 per share. The options contain various service and performance-based vesting conditions. Specifically, a portion of the options vest solely based on a graded four pre-money During fiscal year 2020, the Company issued 1,012,066 stock options to its employees and consultants collectively at exercise prices ranging between $1.63 and $1.81. Stock options granted to employees were subject to graded service-based vesting over the period of four years (primarily), subject, in each case, to the individual’s continued service through the applicable vesting date. In 2019, the Company issued 58,203 stock options to nonemployees in connection with their respective advisory services to the Company at exercise prices of $1.63. There were no stock options issued to nonemployees during the years ended December 31, 2021 and 2020. Stock options granted to one of the nonemployees are subject to both performance and service-based conditions wherein vesting is contingent upon meeting certain business development goals per year and subject to continued services as senior advisor to the Company. Whereas stock options granted to another nonemployee is subject to a standard four-year time-based vesting schedule with 1/16 The following table summarizes activity in relation to the Company’s stock options issued to employees, founders and consultants: Number of Weighted Weighted Date Fair Value Weighted Average Remaining Contractual Life Aggregate Intrinsic Value (years) Balance at January 1, 2021 3,182,758 $ 1.39 $ 0.76 8.59 $ 8,636,744 Granted — — — — Exercised 106,480 0.97 0.54 2,882,631 Forfeited 224,250 1.44 0.78 5,965,765 Expired 25,629 1.68 0.91 675,649 Balance at December 31, 2021 2,826,399 $ 1.40 $ 0.77 7.60 $ 75,296,955 Exercisable at December 31, 2021 1,392,684 1.15 0.62 7.31 37,456,625 Expected to vest at December 31, 2021 1,433,715 1.65 0.84 7.87 37,840,330 As of December 31, 2021, there was approximately $0.9 million of unrecognized compensation cost related to options under the Plan which is expected to be recognized over a weighted average period of 1.1 years. The Company recognizes compensation expense for the options equal to the fair value of the equity-based compensation awards over the vesting period of such awards. The fair values associated with the options are estimated on the date of grant using the Black-Scholes option-pricing model using the following assumptions: 2020 Expected annual dividend yield 0.00 % Expected volatility 51.78 % Risk-free rate of return 0.75 % Expected option term (years) 5.98 The Black-Scholes option pricing model requires the input of certain subjective assumptions, including (a) the expected stock price volatility, (b) the calculation of expected term of the award, (c) the risk-free interest rate and (d) expected dividends. Due to the lack of company-specific historical and implied volatility data for trading the Company’s stock in the public market, the Company has based its estimate of expected volatility on the historical volatility of a group of similar companies that are publicly traded. The historical volatility is calculated based on a period of time commensurate with the expected term assumption. The computation of expected volatility is based on the historical volatility of a representative group of companies with similar characteristics to the Company, including stage of product development and digital manufacturing industry focus. The Company is a technology and services platform positioned as a supply chain solution and the representative group of companies has certain similar characteristics to the Company. The Company believes the group selected has sufficient similar economic and industry characteristics and includes companies that are most representative of the Company. The expected term is applied to the stock option grant group as a whole, as the Company does not expect substantially different exercise or post-vesting termination behavior among its employee population. For options granted to nonemployees, the Company utilizes the contractual term of the arrangement as the basis for the expected term assumption. The risk-free interest rate is based on a treasury instrument whose term is consistent with the expected life of the options. The expected dividend yield is assumed to be zero as the Company has never paid dividends and has no current plans to pay any dividends on its Common Stock, which is similar to the Company’s peer group. Restricted Stock Units As of December 31, 2021 and 2020, the Company has issued 2,205,452 and 235,150, respectively, of RSUs with a weighted average grant date fair value of $16.93 and $1.97 per RSU, respectively. Of the 2,205,452 RSUs issued as of December 31, 2021, 1,219,695 are standard RSUs and 985,757 are founder RSUs. Standard employee RSUs contain both service and performance conditions wherein vesting is generally subject to a requisite four year service period, whereby the award vests 25% on the one-year As of December 31, 2021, unrecognized compensation costs associated with outstanding RSUs was $35.8 million. Founder RSUs include a portion that vests upon the closing of a SPAC transaction or the first IPO to occur following February 1, 2021, and a portion that will vest on the first day following the lapse of the Lock-up See below for a summary of RSU activity for the year ended December 31, 2021: Number of units Weighted average Non-vested 219,252 $ 1.97 Granted 1,970,302 18.72 Vested — — Forfeited (110,023 ) 13.63 Non-vested 2,079,531 $ 17.22 The stock-based compensation expense associated with RSUs will not be recognized until the completion of a Liquidity Event, at which time RSUs whose service conditions have been met will vest and the associated compensation costs will be recognized as stock-based compensation expense. As of December 31, 2021, the service conditions for 166,800 of the outstanding 1,093,774 standard employee RSUs have been achieved. The remaining outstanding employee RSUs are expected to achieve their service conditions over a weighted average period of approximately 1.4 years.

The Company had total treasury shares of 650,000 as of December 31, 2021 and 2020, respectively. The Company has not retired any treasury shares as of December 31, 2021. Preferred Equity All preferred equity is convertible at the option of the holder and automatically upon contingent events. All preferred equity participates in dividends with Common Stock on an as-converted Series Seed Preferred Shares The Board of Directors has authorized up to 400,000 Series Seed shares. As of December 31, 2021 and 2020, there were 400,000 Series Seed Preferred Shares issued and outstanding, at the original issuance price of $4.00/share. The Series Seed Preferred shares were entitled to receive a 6% cumulative dividend on the original issue price of the Series Seed Preferred Shares until the first issuance of Series A-1 A-1 Series Seed-1 The Board of Directors has authorized up to 515,779 Series Seed-1 Seed-1 price of $5.3911/share. The Series Seed-1 Seed-1 A-1 Seed-1 A-1 Series A Preferred Shares The Board of Directors has authorized up to 5,706,349, 2,574,478, and 2,713,324 Series A-1, A-2, A-3 A-1, A-2, A-3, A-1, A-2 A-3 Series B Preferred Shares The Board of Directors has authorized up to 5,131,673 Series B Preferred Shares. As of December 31, 2021 and 2020, there were 4,205,059 Series B Preferred Shares issued and outstanding, respectively, at the original issue price of $13.49 per share for a total liquidation preference of $56.7 million as of December 31, 2021 and 2020. The holders of record of Series B Preferred Shares are entitled to elect one member to the Board of Directors. Liquidation Preferences In the event of voluntary or involuntary liquidation or dissolution, the remaining assets available for distribution are distributed in the following order pursuant to their respective liquidation preference amounts: Series B, Series A-1, A-2, A-3, Seed-1. Redemption The preferred shares are redeemable upon a liquidation event, deemed liquidation event, or pursuant to the redemption options (as defined in the underlying agreements) providing the holders of preferred shares the option to force the Company to redeem their shares after seven years from the Series B original issuance date at the original issuance price plus dividends declared. The redemption feature of each issuance of preferred shares is not solely within the control of the Company; they are each also redeemable at the option of the holder. As such, each issuance of preferred stock is classified in temporary equity as redeemable preferred stock and measured at redemption value. The preferred stock is not currently redeemable, but it is probable that the preferred stock will become redeemable in the future and therefore the Company has elected an accounting policy to subsequently measure the preferred stock at current redemption value.

Fair Value Measurements

Fair Value Measurements	12 Months Ended
	Dec. 31, 2021
Fair Value Measurements	Note 10 – Fair Value Measurements The Company measures the fair value of financial instruments using a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value into three broad levels. Each level of input has different levels of subjectivity and difficulty involved in determining fair value. Level 1 - Inputs used to measure fair value are unadjusted quoted prices that are available in active markets for the identical assets or liabilities as of the reporting date. Therefore, determining fair value for Level 1 investments generally does not require significant judgment, and the estimation is not difficult. Level 2 - Pricing is provided by third-party sources of market information obtained through investment advisors. The Company does not adjust for or apply any additional assumptions or estimates to the pricing information received from its advisors. Level 3 - Inputs used to measure fair value are unobservable inputs that are supported by little or no market activity and reflect the use of significant management judgment. These values are generally determined using pricing models for which the assumptions utilize management’s estimates of market participant assumptions. The determination of fair value for Level 3 instruments involves the most management judgment and subjectivity. The Company’s financial assets and liabilities that are measured at fair value on a recurring basis as of December 31, 2021 and 2020 by level within the fair value hierarchy are as follows: December 31, 2021 Quoted prices in Significant Significant (Level 1) (Level 2) (Level 3) Cash sweep and money mar ket $ 8,701,895 $ $ Related party derivative liabilities $ — $ — $ 4,395,000 Warrant liability $ — $ — $ 2,968,435 December 31, 2020 Quoted prices in Significant Significant (Level 1) (Level 2) (Level 3) Cash sweep and money market accounts $ 17,562,823 $ — $ — Warrant liability $ — $ — $ 199,408 There were no transfers between Level 1, 2 or 3 during the periods ended December 31, 2021 and December 31, 2020 .

The Company previously valued the Forward Purchase Agreement based on the trading price of the Public Warrants, which was considered Level 2 as there was an exercise option prior to the issuance of the Side Letter. As such, the Company transferred the Forward Purchase Agreement from a Level 2 to a Level 3 liability, due to the use of the updated valuation method discussed above which includes a significant unobservable input, and factoring in assumption of the closing of the Business Combination. Outside of the transfer of the Forward Purchase Agreement from Level 2 to Level 3, there were no transfers between Levels 1, 2, and 3 during the year ended December 31, 2021.

Net Loss Per Share

Net Loss Per Share	12 Months Ended

Earnings Per Share [Abstract]
Net Loss Per Share	NOTE 14 – NET LOSS PER SHARE The Company computes basic loss per share using net loss attributable to Common Stockholders and the weighted-average number of Common Stock shares outstanding during each period. Diluted earnings per share include shares issuable upon exercise of outstanding stock options and stock-based awards where the conversion of such instruments would be dilutive. The Company’s potentially dilutive securities, which include stock options, unvested restricted stock awards/units, convertible notes, redeemable convertible preferred stock and warrants to purchase shares of redeemable convertible preferred stock, have been excluded from the computation of diluted net loss per share as the effect would be to reduce the net loss per share. Therefore, the weighted average number of common shares outstanding used to calculate both basic and diluted net loss per share attributable to the Company’s stockholders’ is the same. Presented in the table below is a reconciliation of the numerator and denominator for the basic and diluted earnings calculations for the years ended December 31, 2021 and 2020 is as follows: December 31, 2021 December 31, 2020 Income (loss) available to Common Stockholders per share: Net loss $ (67,883,898 ) $ (21,671,394 ) Weighted average common shares outstanding: Basic and Diluted 4,139,275 2,950,556 Net loss per share – Basic and Diluted $ (16.40 ) $ (7.34 ) The computation of diluted net loss per share excluded 23,081,483 and 17,205,650 shares in 2021 and 2020, respectively, because their inclusion would have had an anti-dilutive effect on net loss per share

Summary of Significant Accoun_2

Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2021
Emerging Growth Company	Emerging Growth Company As an emerging growth company (“EGC”), the Jumpstart Our Business Startups Act (“JOBS Act”) allows the Company to delay adoption of new or revised accounting pronouncements applicable to public companies until such pronouncements are applicable to private companies. The Company has elected to use this extended transition period under the JOBS Act until such time the Company is no longer considered to be an EGC. The adoption dates discussed below reflect this election.
Use of Estimates	Use of Estimates The preparation of the consolidated interim financial statements in conformity with U.S. GAAP requires management to make estimates, judgments and assumptions that affect the reported amounts of assets and liabilities, related disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses for the periods presented. The Company’s most significant estimates and judgements involve valuation of the Company’s debt and equity securities, including assumptions made in the fair value of warrants, derivatives, and stock-based compensation; the useful lives of fixed assets; and allowances for doubtful accounts. Although the Company regularly assesses these estimates, actual results could differ materially from these estimates. Changes in estimates are recorded in the period in which they become known. The Company bases its estimates on historical experience and various other assumptions that it believes to be reasonable under the circumstances. Actual results may differ from management’s estimates if these results differ from historical experience or other assumptions prove not to be substantially accurate, even if such assumptions are reasonable when made.
Cash and Cash Equivalents	Cash and Cash Equivalents The Company considers all highly liquid investments with an original maturity of 90 days or less, or with the ability to redeem amounts on demand, to be cash and cash equivalents. The carrying amount of cash equivalents are reported at cost, which approximates their fair value.
Concentrations of Credit Risk	Significant Customers and Concentration of Credit Risks The Company is subject to credit risk primarily through its accounts receivable. Credit is extended to customers based on a credit review. The credit review considers each customer’s financial condition, including the customer’s established credit rating or the Company’s assessment of the customer’s creditworthiness based on their financial statements absent a credit rating, local industry practices, and business strategy. A credit limit and terms are established for each customer based on the outcome of this review. The Company performs on- Significant customers are those that represent more than 10% of the Company’s total revenue or accounts receivable. For the customers identified, revenue as a percentage of total revenue and accounts receivable as a percentage of net accounts receivable are as follows: December 31, 2021 December 31, 2020 Revenue for the years ended Customer A <10 % 21.6 % December 31, 2021 December 31, 2020 Accounts receivable Customer A < 1 % 24.2 % Customer B <10 % 13.3 %
Fair Value Measurements	Fair Value Measurements Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. A hierarchy has been established for inputs used in measuring fair value that maximizes the use of observable inputs and minimizes the use of unobservable inputs by requiring that the most observable inputs be used when available. The Company has determined the estimated fair value of its financial instruments including stock-based awards, derivatives, and certain warrants, which are accounted for as liabilities, based on appropriate valuation methodologies; however, considerable judgment is required to develop these estimates. Accordingly, these estimated fair values are not necessarily indicative of the amounts the Company could realize in a current market exchange. The estimated fair values can be materially affected by using different assumptions or methodologies. The carrying amounts reported in the consolidated balance sheets for cash and cash equivalents represent cost, which approximates fair value. The carrying amounts reported in the consolidated balance sheets for accounts receivable, accounts payable, and accrued liabilities approximate fair value due to their short-term maturities. With the exception of the Company’s Related Party Convertible Notes, the fair value of the Company’s debt approximates their carrying values based on the variable nature of interest rates and current market rates available. The Company considers its debt to be a Level 3 measurement in the fair value hierarchy as significant judgment is involved to determine the fair value of embedded conversion features. Refer to Note 10 for further information regarding fair value.
Net Income Per Share of Common Stock	Net Loss Per Share The Company applies the two-class two-class two-class two-class Basic net loss per share attributable to stockholders is computed by dividing net loss attributable to the Company’s stockholders by the weighted-average number of common shares outstanding during the period without consideration of potentially dilutive Common Stock. Diluted net loss per share attributable to the Company’s stockholders reflects the potential dilution that could occur if securities or other contracts to issue Common Stock were exercised or converted into Common Stock or resulted in the issuance of Common Stock that then shared in the earnings of the Company unless inclusion of such shares would be anti-dilutive. For periods in which the Company reports net losses, diluted net loss per common share attributable to the Company’s stockholders is the same as basic net loss per common share attributable to the Company’s stockholders, because potentially dilutive common shares are not assumed to have been issued if their effect is anti-dilutive. Refer to Note 14 for further information regarding net loss per share.
Income Taxes	Income Taxes Income taxes are accounted for under the asset and liability method. Deferred income tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases, and net operating loss and tax credit carry forwards. Deferred income tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred income tax assets and liabilities of a change in tax rates is recognized in the consolidated statements of net loss and comprehensive loss in the period that includes the enactment date. Deferred income tax assets are reduced by a valuation allowance when it is more likely than not that some portion of the deferred income tax assets will not be realized. The Company does not have any uncertain tax positions. A valuation allowance is provided unless it is more likely than not that the deferred tax asset will be realized. Assessing whether deferred tax assets are realizable requires significant judgement. In the determination of the appropriate valuation allowance, the Company considers future reversals of existing taxable temporary differences, the most recent projections of future business results, prior earnings history, carry back and carry forward periods, and prudent tax strategies. Assessments for the realization of deferred tax assets made at a given balance sheet date are subject to change in the future. Refer to Note 6 for further information regarding income taxes.
Recent Accounting Pronouncements	Recently issued accounting pronouncements Recently Adopted Accounting Pronouncements In August 2018, the FASB issued ASU No. 2018-15, Intangibles — Goodwill and Other — Internal-Use 350-40): internal-use internal-use In August 2020, the FASB issued ASU 2020-06, Debt—Debt with Conversion and Other Options (Subtopic 470- 20) and Derivatives and Hedging—Contracts in Entity’s Own Equity (Subtopic 815-40): Recently Issued Accounting Pronouncements not yet adopted as of December 31, 2021 In December 2019, the FASB issued ASU 2019-12, Income Taxes (Topic 740)—Simplifying the Accounting for Income Taxes Income Taxes after December 15, 2022 and interim periods within that year, and early adoption is permitted.

In February 2016, the FASB issued ASU 2016-02, Leases right-of-use 2020-05, In June 2016, the FASB issued ASU 2016-13, Financial Instruments—Credit Losses: Measurement of Credit Losses on Financial Instruments
Segment Information	Segment Information The Company operates and manages its business as one operating and reportable segment. The Company’s chief executive officer, who is the chief operating decision maker, reviews financial information on an aggregate basis for purposes of evaluating financial performance and allocating resources. The Company’s long-lived assets and customers are all substantially located in the United States.
Accounts Receivable	Accounts Receivable In evaluating the collectability of accounts receivable, the Company assesses a number of factors, including specific customers’ abilities to meet their financial obligations, the length of time a receivable is past due, and historical collection experience. If circumstances related to specific customers change, or economic conditions deteriorate such that the Company’s past collection experience is no longer relevant, its estimate of the recoverability of accounts receivable could be further reduced from the levels provided for in the consolidated financial statements. All accounts or portions thereof considered uncollectible are written off to the allowance for doubtful accounts in the period this information becomes known. Recoveries of trade receivables previously written off are recorded when received. The components of accounts receivable are as follows: December 31, 2021 December 31, 2020 Trade receivables $ 7,945,078 $ 5,451,252 Allowance for doubtful accounts (929,800 ) (404,755 ) Total accounts receivable $ 7,015,278 $ 5,046,497 The following table summarizes activity in the allowance for doubtful accounts : December 31, 2021 December 31, 2020 Balance at beginning of period $ (404,755 ) $ (190,205 ) Provision for uncollectible accounts (641,357 ) (710,882 ) Uncollectible accounts written off 116,312 496,332 Balance at end of period $ (929,800 ) $ (404,755 )
Inventories	Inventories The Company’s inventories consist of raw materials, work-in-process, Inventories consisted of the following: December 31, 2021 December 31, 2020 Raw materials $ 432,461 $ 162,397 Work-in-process 16,310 107,770 Finished goods — 4,144 Total Inventories $ 448,771 $ 274,311 Cost is determined using the weighted-average method. The Company performs on-going
Property and Equipment, net	Property and Equipment, net The Company’s property and equipment primarily consists of advanced manufacturing machinery, quality measurement equipment, other manufacturing infrastructure, office equipment and furniture, computer hardware, internally developed software, and networking equipment. Depreciation is computed using the straight-line method over the estimated useful life by asset category, or in the case of leasehold improvements, the shorter of the lease term including any renewal periods reasonably assured to be exercised at inception, or the estimated useful life of the asset category. Repairs and maintenance are expensed as incurred, while betterments and improvements that the Company determines extend the useful life or add functionality of property and equipment are capitalized. Property and equipment are depreciated over the estimated useful life of the asset categories as follows: Advanced Manufacturing Machinery & Quality Equipment 5 – 10 Years Computer & Office Hardware 5 Years Furniture & Fixtures 7 Years Internally Developed Software 3 – 5 years Leasehold Improvements Lesser of lease term The Company periodically reviews each asset category’s estimated useful life based upon actual experience and expected future utilization. A change in useful life is treated as a change in accounting estimate and is applied prospectively. The Company reviews the carrying amounts of property and equipment for potential impairment when events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. In evaluating recoverability, the Company groups assets and liabilities at the lowest level such that the identifiable cash flows relating to the group are largely independent of the cash flows of other assets and liabilities, which are each determined to be an asset group. The Company then compares the carrying amount of each asset group to the estimated undiscounted future cash flows attributable to the asset group. If the estimated undiscounted future cash flows for the asset group are not at least equal to the carrying amount, the Company estimates the fair value of the asset group and an impairment charge is recorded at the amount by which the carrying amount of the asset or asset group exceeds the fair value, if applicable. In addition, the remaining depreciation period for the impaired asset or asset group would be reassessed and, if necessary, revised. For the years ended December 31, 2021 and December 31, 2020, the Company did not recognize any impairment of its property and equipment. Refer to Note 4 for further information regarding property and equipment. Software applications developed for internal use are capitalized as internally developed software. Costs are capitalized when: (i) the preliminary project stage is completed (i.e., the application development stage) and (ii) it is probable that the software will be completed and used for its intended function. The Company also capitalizes costs related to specific upgrades and enhancements when it is probable the expenditures will result in additional functionality. Costs incurred for maintenance, minor upgrades and enhancements are expensed as incurred within general and administrative expense in the consolidated statements of net loss and comprehensive loss.
Debt and Deferred Financing Fees	Debt and Deferred Financing Fees Debt discounts are presented on the balance sheet as a direct deduction from the carrying amount of that related debt. Refer to Note 5 for further information regarding debt. Costs incurred in connection with the Company’s debt instruments consist principally of debt issuance costs and have been deferred and are being amortized over the terms of the related debt agreements using the effective interest method. Deferred financing fees are presented on the consolidated balance sheets as direct reductions to debt balances.
Research and Development Costs	Research and Development Costs Management invests resources to advance the development of its products and services for its customers, including the development of the cloud manufacturing software platform. Research and development costs represent costs incurred to support the advancement of new product platforms, consumables, and activities to enhance manufacturing capabilities. Research and development costs are comprised of prototype parts, design expense, employee-related personnel expense, and an allocated portion of overhead costs. Research and development costs are expensed as incurred.
Advertising Costs	Advertising Costs Advertising costs are expensed as incurred. Advertising expenses consist primarily of media advertising costs, trade and customer marketing expenses, sales and marketing related personnel, and public relations expenses which aim to strengthen the leadership of the Company’s brand in key vertical markets. Advertising costs were approximately $7.9 million and $1.2 million for the years ended December 31, 2021 and 2020, respectively. All advertising expenses are recorded in Sales and marketing expense in the consolidated statements of net loss and comprehensive loss.
Stock-Based Compensation—Options, RSUs and Warrants	Stock-Based Compensation—Options, RSUs and Warrants The Company accounts for stock-based compensation awards in accordance with Financial Accounting Standards Board (“FASB”) ASC 718, Compensation—Stock Compensation The Company’s stock-based awards are subject to service and/or performance-based vesting conditions. The Company recognizes compensation expenses for awards with only a service condition over the explicit service period using the straight-line method. For awards subject to a service and performance condition, compensation cost is recognized over the longer of the explicit, implicit, or derived period using the accelerated attribution method for cost allocation, as long as the performance condition is probable of achievement. At each reporting period, the Company evaluates the probability that its performance-based stock options will be earned and adjusts its previously recognized compensation expense as necessary. If the achievement of the respective performance metrics is not probable or the respective performance goals are not met, the Company reverses its previously recognized compensation expense. In accordance with ASC 718, excess tax benefits realized from the exercise of stock-based awards are classified as cash flows from operating activities. All excess tax benefits and tax deficiencies (including tax benefits of dividends on share-based payment awards) are recognized as income tax expense or benefit in the consolidated statements of net loss and comprehensive loss. The Company accounts for stock-based compensation awards issued to nonemployees for services, as prescribed by ASC 718, at either the fair value of the services rendered or the instruments issued in exchange for such services, whichever is more readily determinable using the measurement date guidelines enumerated in Accounting Standards Update (“ASU”) 2018-07, Improvements to Nonemployee Share-Based Payment Accounting 2018-07”). The Company has elected to account for forfeitures as they occur for both employee and nonemployee awards. Refer to Note 9 for further information regarding stock-based compensation.
Redeemable Convertible Preferred Stock	Redeemable Convertible Preferred Stock The Series Seed, Seed-1, A-1, A-2, A-3,
Warrants	Warrants The Company accounts for its warrants issued with other debt and equity instruments in accordance with ASC 480, Distinguishing Liabilities from Equity
Treasury stock	Treasury stock Treasury stock purchases are accounted for under the cost method whereby the entire cost of the acquired stock is recorded as treasury stock. Gains, and losses to the extent that gains were previously recorded, on the subsequent reissuance of shares are credited or charged to paid-in
Revenue Recognition	Revenue Recognition The Company determines revenue recognition through the following steps: • Identification of the contract, or contracts, with a customer; • Identification of the performance obligations in the contract; • Determination of the transaction price; • Allocation of the transaction price to the performance obligations in the contracts; and • Recognition of revenue when, or as, the Company satisfies a performance obligation The Company’s primary source of revenue is from product sales of manufactured parts. Fast Radius has contracts with customers where the transfer of control of the specified good varies from contract to contract, but predominantly occurs upon shipment. The Company does not act as an agent in any of its revenue arrangements. Fast Radius seldom offers assurance-type warranties in the ordinary course of business; however, when such warranties are included, they generally have a service life of four years beginning from the date of product purchase. In the event of a failure of products covered under the warranties, the Company may repair or replace the products at the customer’s discretion. As of December 31, 2021 and 2020, the Company has not incurred any warranty related costs related to products covered by this warranty. The Company also derives revenue from consulting agreements, in which the Company produces digital assets (CAD files) and physical assets (prototypes). For consulting contracts, the deliverables are combined to be one performance obligation within the context of the contract, and revenue is recognized over time or at a point-in- work-in- (cost-to-cost point-in-time Payments are generally due within a range of 30 to 90 days after the performance obligation has been satisfied. Revenue from consulting agreements is not material. The Company charges certain customers shipping and handling fees. These fees are recorded within revenue after transfer of control of the products to customers. Revenues related to shipping and handling were $0.8 million and $0.4 million in 2021 and 2020, respectively. When shipping and handling services are performed before transfer of control to customers, they are accounted for as a fulfillment cost and are included in cost of revenues as incurred. The Company will contract with third parties to produce certain components of a customer order. Costs paid in advance of production are recorded in current assets as prepaid production costs until control of the product is transferred to the customer. Under such outsourced manufacturing arrangements, the Company is the primary obligor to its customer. Contract liabilities consist of fees paid by the Company’s customers for which the associated performance obligations have not been satisfied and revenue has not been recognized based on the Company’s revenue recognition criteria described above. Contract assets are recorded when the Company has a right to consideration in exchange for goods or services that it has transferred to a customer but for which payment is conditional on more than just the passage of time. Given the nature of the Company’s contracts, the Company did not have any contract assets as of December 31, 2021 or 2020, respectively. Refer to Note 3 for further information regarding revenue.

ECP Environmental Growth Opportunities Corp
Basis of Presentation	Basis of Presentation The accompanying consolidated financial statements are presented in conformity with accounting principles generally accepted in the United States of America (“GAAP”) and pursuant to the rules and regulations of the SEC.
Principles of Consolidation	Principles of Consolidation The consolidated financial statements include the accounts of the Company and its wholly owned subsidiary, Merger Sub, as of December 31, 2021. Merger Sub had no assets or liabilities as of December 31, 2021. All significant intercompany transactions and balances have been eliminated in consolidation.
Emerging Growth Company	Emerging Growth Company The Company is an “emerging growth company,” as defined in Section 2(a) of the Securities Act, as modified by the Jumpstart Our Business Startups Act of 2012 (the “JOBS Act”), and it may take advantage of certain exemptions from various reporting requirements that are applicable to other public companies that are not emerging growth companies including, but not limited to, not being required to comply with the auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act of 2002, reduced disclosure obligations regarding executive compensation in its periodic reports and proxy statements, and exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and stockholder approval of any golden parachute payments not previously approved. Further, Section 102(b)(1) of the JOBS Act exempts emerging growth companies from being required to comply with new or revised financial accounting standards until private companies (that is, those that have not had a Securities Act registration statement declared effective or do not have a class of securities registered under the Exchange Act) are required to comply with the new or revised financial accounting standards. The JOBS Act provides that an emerging growth company can elect to opt out of the extended transition period and comply with the requirements that apply to non-emerging
Use of Estimates	Use of Estimates The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of expenses during the reporting period. Making estimates requires management to exercise significant judgment. It is at least reasonably possible that the estimate of the effect of a condition, situation or set of circumstances that existed at the date of the consolidated financial statements, which management considered in formulating its estimate, could change in the near term due to one or more future confirming events. Accordingly, the actual results could differ significantly from those estimates.
Cash and Cash Equivalents	Cash and Cash Equivalents The Company considers all short-term investments with an original maturity of three months or less when purchased to be cash equivalents. The Company had $82,234 in cash and no cash equivalents, outside of the funds held in the Trust Account, as of December 31, 2021.
Derivative Financial Instruments	Derivative Financial Instruments The Company accounts for the Warrants, Forward Purchase Agreement (as defined below), and Working Capital Loan conversion option (collectively, the “Instruments”) in accordance with the guidance contained in ASC 815-40 re-measurement
Marketable Securities Held in Trust Account	Marketable Securities Held in Trust Account At December 31, 2021, the assets held in the Trust Account were invested in money market funds.
Class A Common Stock Subject to Possible Redemption	Class A Common Stock Subject to Possible Redemption The Company accounts for its Class A common stock subject to possible redemption in accordance with the guidance in ASC Topic 480 “Distinguishing Liabilities from Equity.” Common stock subject to mandatory redemption is classified as a liability instrument and is measured at fair value. Conditionally redeemable common stock (including common stock that features redemption rights that is either within the control of the holder or subject to redemption upon the occurrence of uncertain events not solely within the Company’s control) is classified as temporary equity. At all other times, common stock is classified as shareholders’ equity. The Company’s Class A common stock features certain redemption rights that are considered to be outside of the Company’s control and subject to occurrence of uncertain future events. Accordingly, at December 31, 2021, 34,500,000 shares of Class A common stock subject to possible redemption are presented as temporary equity outside of the shareholders’ equity section of the Company’s balance sheets. The Company recognizes changes in redemption value immediately as they occur and adjusts the carrying value of redeemable common stock to equal the redemption value at the end of each reporting period. Increases or decreases in the carrying amount of redeemable common stock are affected by charges against additional paid in capital and accumulated deficit. For the year ended December 31, 2021, the Company recorded a remeasurement of Class A common stock to the redemption value in the amount of $32,015,603. The Class A common stock subject to possible redemption reflected in the consolidated balance sheet at December 31, 2021 is reconciled in the following table: Gross proceeds $ 345,000,000 Less: Proceeds allocated to public warrants (12,880,575 ) Deferred underwriting fees (12,075,000 ) Other offering costs (7,060,028 ) Plus: Total remeasurement of carrying value to redemption value 32,015,603 Class A common stock subject to possible redemption $ 345,000,000
Concentrations of Credit Risk	Concentrations of Credit Risk Financial instruments that potentially subject the Company to concentration of credit risk consist of a cash account in a financial institution which, at times may exceed the Federal Deposit Insurance Corporation (FDIC) coverage of $250,000. At December 31, 2021, the Company had not experienced losses on this account and management believes the Company is not exposed to significant risks on such account.
Financial Instruments	Financial Instruments Except for the Warrant and Forward Purchase Agreement Liabilities as described above, the fair value of the Company’s assets and liabilities, which qualify as financial instruments under the Financial Accounting Standards Board (the “FASB”) ASC 820, “Fair Value Measurements and Disclosures,” approximates the carrying amounts represented in the consolidated balance sheets.
Fair Value Measurements	Fair Value Measurements Fair value is defined as the price that would be received for sale of an asset or paid for transfer of a liability, in an orderly transaction between market participants at the measurement date. GAAP establishes a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). These tiers include: • Level 1, defined as observable inputs such as quoted prices for identical instruments in active markets; • Level 2, defined as inputs other than quoted prices in active markets that are either directly or indirectly observable such as quoted prices for similar instruments in active markets or quoted prices for identical or similar instruments in markets that are not active; and • Level 3, defined as unobservable inputs in which little or no market data exists, therefore requiring an entity to develop its own assumptions, such as valuations derived from valuation techniques in which one or more significant inputs or significant value drivers are unobservable. In some circumstances, the inputs used to measure fair value might be categorized within different levels of the fair value hierarchy. In those instances, the fair value measurement is categorized in its entirety in the fair value hierarchy based on the lowest level input that is significant to the fair value measurement. As of December 31, 2021, the carrying values of cash, prepaid expenses, other current assets, accounts payable and accrued expenses approximate their fair values due to the short-term nature of the instruments. The Company’s portfolio of marketable securities held in the Trust Account is comprised of money market funds. The fair values of Forward Purchase Agreement and Private Placement Warrants have been estimated using the trading price of the Public Warrants. Public Warrants are valued based on quoted price in active markets. See Note 5 and 6 for further discussion of the pertinent terms of the Warrants and Forward Purchase Agreement and Note 8 for further discussion of the methodology used to determine the value of the Warrants and Forward Purchase Agreement.
Offering Costs	Offering Costs Offering costs consist of legal, accounting, underwriting and other costs incurred through the consolidated balance sheet date that are directly related to the Initial Public Offering. Upon the completion of the Initial Public Offering in February 2021, the offering costs were allocated using the relative fair values of the company common stock and its Warrants. The costs allocated to Warrants were recognized in other expenses and those related to the Company’s common stock were charged to temporary equity.
Net Income Per Share of Common Stock	Net Income Per Share of Common Stock Net income per share of common stock is computed by dividing net income (loss) by the weighted average number of shares issued and outstanding during the period. The Company has not considered the effect of their Forward Purchase Agreement, warrants sold in the Initial Public Offering, private placement to purchase Class A common stock, and Working Capital Loan warrants in the calculation of diluted income per share, since the instruments are not dilutive. At December 31, 2021, the Company did not have any dilutive securities and other contracts that could, potentially, be exercised or converted into common stock and then share in the earnings of the Company under the treasury stock method. As a result, diluted income per share is the same as basic income per share for the periods presented. The Company has two classes of shares, which are referred to as Class A common stock and Class B common stock (the “Founder Shares”). Earnings are shared pro rata between the two classes of shares as long as an Initial Business Combination is consummated. Remeasurement associated with the redeemable shares of Class A common stock is excluded from earnings per share as the redemption value approximates fair value. A reconciliation of the earnings per share is below: For the Year December 31, 2021 For The Period Numerator: Earnings allocable to Redeemable Class A Common Stock Net Earnings allocable to Redeemable Class A Common Stock $ 4,660,201 $ — Denominator: Weighted Average Share Outstanding, Redeemable Class A Common Stock Basic and diluted weighted average shares outstanding, Redeemable Class A 30,624,658 — Basic and diluted net earnings per share, Redeemable Class A $ 0.15 $ — For the Year December 31, 2021 For The Period Non-Redeemable Numerator: Net Income allocable to Non-Redeemable Net Income allocable to Non-Redeemable $ 1,293,249 $ (20 ) Denominator: Weighted Average Non-Redeemable Basic and diluted weighted average shares outstanding, Non-Redeemable 8,498,630 7,500,000 Basic and diluted net earnings per share, Non-Redeemable $ 0.15 $ 0.00
Income Taxes	Income Taxes The Company complies with the accounting and reporting requirements of ASC Topic 740, “Income Taxes,” which requires an asset and liability approach to financial accounting and reporting for income taxes. Deferred income tax assets and liabilities are computed for differences between the financial statement and tax bases of assets and liabilities that will result in future taxable or deductible amounts, based on enacted tax laws and rates applicable to the periods in which the differences are expected to affect taxable income. Valuation allowances are established, when necessary, to reduce deferred tax assets to the amount expected to be realized. ASC Topic 740 prescribes a recognition threshold and a measurement attribute for the financial statement recognition and measurement of tax positions taken or expected to be taken in a tax return. For those benefits to be recognized, a tax position must be more-likely-than-not to be sustained upon examination by taxing authorities. The Company’s management determined that the United States is the Company’s only major tax jurisdiction. The Company recognizes accrued interest and penalties related to unrecognized tax benefits as income tax expense. There were no unrecognized tax benefits and no amounts accrued for interest and penalties as of December 31, 2021.
