Summary of Significant Accounting Policies | Summary of Significant Accounting Policies (a) Basis of Presentation The accompanying consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”). The Business Combination between Newborn, a Special Purpose Acquisition Company (“SPAC”), the Company, prior to the Business Combination a wholly owned subsidiary of Newborn, and Nuvve Corp., prior to the Business Combination a privately held operating company, pursuant to which the Company acquired the outstanding shares of Nuvve Corp. (see Business Combination below) was accounted for as a reverse recapitalization in accordance with U.S. GAAP (the “Reverse Recapitalization”). Under this method of accounting, Newborn was treated as the “acquired” company for financial reporting purposes. Accordingly, for accounting purposes, the Reverse Recapitalization was treated as the equivalent of Nuvve Corp. issuing stock for the net assets of Newborn, accompanied by a recapitalization. The net assets recorded from Newborn are stated at historical cost, with no goodwill or other intangible assets recorded. The consolidated assets, liabilities and results of operations prior to the Reverse Recapitalization are those of Nuvve Corp. The shares and corresponding capital amounts and earnings per share available for common stockholders prior to the Business Combination have been retroactively restated to reflect the exchange ratio established in the Business Combination. In accordance with Accounting Standards Codification ("ASC") 205-40, Presentation of Financial Statements - Going Concern , the Company has evaluated whether there are conditions and events, considered in the aggregate, that raise substantial doubt about its ability to continue as a going concern within one year after the that the consolidated financial statements are issued. Since inception, the Company has incurred recurring losses and negative cash flows from operations since inception and has an accumulated deficit of $92.9 million as of December 31, 2021. During the year ended December 31, 2021, the Company incurred a operating loss of $27.2 million and used $29.2 million of cash in operations. The Company continues to expect to generate operating losses and negative cash flows and may need additional funding to support its planned operating activities through profitability. The transition to profitability is dependent upon the successful expanded commercialization of the Company's GIVe platform and the achievement of a level of revenues adequate to support its cost structure. The Company expects its cash and cash equivalents as of March 31, 2022 will be sufficient to fund current planned operations for at least the next twelve months from the date of issuance of these consolidated financial statements. Management's expectations with respect to its ability to fund current planned operations is based on estimates that are subject to risks and uncertainties. Actual results could be different from management's estimates and should actual results be less favorable than these estimates management would ultimately need to take corrective steps to improve future operating results and its financial condition. Restatement of Previously Issued Financial Statements Subsequent to the issuance of the company’s consolidated financial statements as of December 2021 and 2020, errors were identified relating to the following: (1) Unvested warrants issued to Stonepeak and Evolve in May 2021, as described in Note 19 , should be accounted for as a single unit of account as opposed to multiple units of account. As a result, these unvested warrants, which were previously recorded in equity, have been reclassified to liabilities on the consolidated balance sheet. As a single unit of account, the unvested warrants’ settlement value is impacted by the amount of capital expenditures associated with Levo’s customer contracts, which caused the unvested warrants to not be indexed to the Company's equity. The unvested warrant liability is adjusted to its estimated fair value at each reporting date. (2) As part of the fair value of warrants and stock option (“Instruments”) granted to Stonepeak and Evolve in May 2021, in conjunction with the formation of Levo, the Company inaccurately capitalized the costs incurred to deferred financing costs, and should have expensed such costs. The Company determined that there was not sufficient basis to record a deferred financing costs associated with Stonepeak and Evolve’s plans to contribute capital to the Levo venture. As a result, the estimated fair value of the Instruments that were previously recorded as a capitalized asset are corrected to recognize an expense upon issuance of the Instruments during the second quarter of 2021. The expense is non-cash and does not impact the existing conditional capital commitment the Company has from Stonepeak and Evolve or the pursuit of customer deployments funded by this conditional capital commitment. The associated income tax expense or benefit and related deferred tax assets or liabilities have been reflected, including the impact of valuation allowance. The following tables summarize the effect of the aforementioned adjustments on the Company's Consolidated Balance Sheet as of December 31, 2021, and the Company's Consolidated Statements of Operations, and Consolidated Statements of Cash Flows for the year ended December 31, 2021: Consolidated Balance Sheet December 31, 2021 December 31, 2021 Assets As Previously Reported Adjustment As Restated Deferred financing costs $ 43,562,847 $ (43,562,847) $ — Total Assets $ 96,477,390 $ (43,562,847) $ 52,914,543 Warrants liability $ 866,000 $ 8,677,000 $ 9,543,000 Total Liabilities $ 14,323,199 $ 8,677,000 $ 23,000,199 Redeemable non-controlling interests, preferred shares, zero par value, 1,000,000 shares authorized, 3,138 shares issued and outstanding; aggregate liquidation preference of $3,200,760 at December 31, 2021 $ 2,885,427 $ 16,472 $ 2,901,899 Stockholders’ (Deficit) Equity Additional paid-in capital $ 127,138,504 $ (4,801,897) $ 122,336,607 Accumulated deficit $ (47,412,470) $ (45,525,393) $ (92,937,863) Nuvve Holding Corp.

All intercompany accounts and transactions have been eliminated upon consolidation. Variable Interest Entities Pursuant to the consolidation guidance, the Company first evaluates whether it holds a variable interest in an entity in which it has a financial relationship and, if so, whether or not that entity is a variable interest entity ("VIE"). A VIE is an entity with insufficient equity at risk for the entity to finance its activities without additional subordinated financial support or in which equity investors lack the characteristics of a controlling financial interest. If an entity is determined to be a VIE, the Company evaluates whether the Company is the primary beneficiary. The primary beneficiary analysis is a qualitative analysis based on power and economics. The Company concludes that it is the primary beneficiary and consolidates the VIE if the Company has both (i) the power to direct the activities of the VIE that most significantly influence the VIE's economic performance, and (ii) the obligation to absorb losses of, or the right to receive benefits from, the VIE that could potentially be significant to the VIE. The Company formed Levo with Stonepeak and Evolve (see Note 19 for details), in which the Company owns 51% of Levo's common units. The Company has determined that Levo is a VIE in which the Company is the primary beneficiary. Accordingly, the Company consolidates Levo and records a non-controlling interest for the share of the entity owned by Stonepeak and Evolve. Assets and Liabilities of Consolidated VIEs The Company's consolidated financial statements include the assets, liabilities and results of operations of VIEs for which the Company is the primary beneficiary. The other equity holders’ interests are reflected in "Net loss attributable to non-controlling interests" in the consolidated statements of operations and "Non-controlling interests" in the consolidated balance sheets. See Note 20 for details of non-controlling interests. The Company began consolidating the assets, liabilities and results of operations of Levo during the quarter ended September 30, 2021. The creditors of the consolidated VIE do not have recourse to the Company other than to the assets of the consolidated VIE. The following table summarizes the carrying amounts of Levo assets and liabilities included in the Company’s consolidated balance sheets at December 31, 2021: December 31, 2021 Assets Cash $ 28,446 Total Assets $ 28,446 Liabilities and Mezzanine Equity Accrued expenses $ 116,754 Derivative liability - non-controlling redeemable preferred shares 511,948 Total Liabilities $ 628,702 (c) Redeemable Non-Controlling Interest - Mezzanine Equity Redeemable non-controlling interest represents the shares of the preferred stock issued by Levo to Stonepeak and Evolve (the "preferred shareholders") who also own 49% of Levo common units. The preferred stock is not mandatorily redeemable or currently redeemable, but it could be redeemable with the passage of time at the election of Levo, the preferred shareholders or a trigger event as defined in the preferred stock agreement. As a result of the contingent put right available to the preferred shareholders, the redeemable non-controlling interests in Levo are classified outside of permanent equity in the Company’s consolidated balance sheets as mezzanine equity. The initial carrying value of the redeemable non-controlling interest is reported at the initial proceeds received on issuance date, reduced by the fair value of embedded derivatives resulting in an adjusted initial carrying value. The adjusted initial carrying value is further adjusted for the accretion of the difference with the redemption price value using the effective interest method. The accretion amount is a deemed dividend recorded against retained earnings or, in its absence, to additional-paid-in-capital. The carrying amount of the redeemable non-controlling interest is measured at the higher of the carrying amount adjusted each reporting period for income (or loss) attributable to the non-controlling interest, or the carrying amount adjusted each reporting period by the accretion amount. See Note 20 for details. (d) Non-controlling interests The Company presents non-controlling interests as a component of equity on its consolidated balance sheets and reports the portion of its earnings or loss for non-controlling interest as net earnings or loss attributable to non-controlling interests in the consolidated statements of operations. (e) Business Combination The Company is party to a merger agreement (as amended, the “Merger Agreement”), dated as of November 11, 2020 and amended as of February 20, 2021, by and among Newborn, a Cayman Islands company, the Company, a Delaware corporation and prior to the Business Combination a wholly owned subsidiary of Newborn, Nuvve Merger Sub Inc., a Delaware corporation and prior to the Business Combination a wholly-owned subsidiary of the Company (the “Merger Sub”), Nuvve Corp., a Delaware corporation, and Ted Smith, an individual, as the representative of the stockholders of Nuvve Corp. On March 16, 2021, Newborn held an extraordinary general meeting of its shareholders, at which Newborn’s shareholders approved the Business Combination, along with certain other related proposals. On March 19, 2021 (the “Closing Date”), the parties consummated the Business Combination. Pursuant to the Merger Agreement, the Business Combination was effected in two steps: (i) Newborn reincorporated to the State of Delaware by merging with and into the Company, with the Company surviving as the publicly-traded entity (the “Reincorporation Merger”); and (ii) immediately after the Reincorporation Merger, Merger Sub merged with and into Nuvve, with Nuvve surviving as a wholly-owned subsidiary of the Company (the “Acquisition Merger”). Immediately prior to the effectiveness of the Reincorporation Merger and the Acquisition Merger, the Company filed its Amended and Restated Certificate of Incorporation with the Delaware Secretary of State, pursuant to which, among other things, the Company changed its name to “Nuvve Holding Corp.” and adopted certain other changes that the Company’s Board of Directors deemed appropriate for an operating public company. In connection with the entry into the Merger Agreement, on November 11, 2020, Newborn entered into subscription agreements (the “Subscription Agreements”) with certain accredited Private Investment in Public Equity investors (the “PIPE Investors”), under which, immediately before the closing of the Business Combination, the PIPE Investors purchased 1,425,000 ordinary shares of Newborn, at a purchase price of $10.00 per share, for an aggregate purchase price of $14,250,000 in a private placement (the “PIPE”). The PIPE Investors also received warrants to purchase 1,353,750 ordinary shares of Newborn (the “PIPE Warrants”) that were identical to Newborn’s other outstanding warrants. Also, on November 11, 2020, Nuvve Corp. entered into a bridge loan agreement with an accredited investor, under which, on November 17, 2020, the investor purchased a $4,000,000 6% Senior Secured Convertible Debenture from Nuvve Corp. (the “Bridge Loan”), which automatically converted into shares of Nuvve Corp.’s common stock immediately before the closing of the Business Combination. Upon the closing of the Reincorporation Merger, each of Newborn’s outstanding units was automatically separated into its constituent securities, and Newborn’s outstanding securities (including the Newborn ordinary shares and Newborn warrants purchased by the PIPE Investors) were converted into a like number of equivalent securities of the Company, except that each of Newborn’s rights was converted automatically into one-tenth of one share of the Company’s common stock in accordance with its terms. Upon the closing of the Acquisition Merger, each share of Nuvve Corp.’s common stock outstanding immediately prior to the effective time of the Acquisition Merger (including the shares issued upon conversion of Nuvve Corp.’s preferred stock and upon conversion of the Bridge Loan as described above) automatically was converted into approximately 0.212403050 shares (the “Closing Exchange Ratio”) of the Company’s common stock, for an aggregate of 9,122,996 shares of the Company’s common stock. Each outstanding option to purchase Nuvve Corp.’s common stock (“Nuvve Options”) was assumed by the Company and converted into an option to purchase a number of shares of the Company’s common stock equal to the number of shares of Nuvve Corp.’s common stock subject to such option immediately prior to the effective time multiplied by the Closing Exchange Ratio, for an aggregate of 1,303,610 shares of the Company’s common stock, at an exercise price equal to the exercise price immediately prior to the effective time divided by the Closing Exchange Ratio. The Closing Exchange Ratio was determined by taking (i) a number of shares of the Company’s common stock equal to (A) the Closing Merger Consideration (as defined below), divided by (B) $10.00 per share, and dividing it by (ii) the sum of (x) the total number of shares of Nuvve Corp.’s common stock outstanding as of immediately prior to closing (including the shares issued upon conversion of Nuvve Corp.’s preferred stock, but excluding the shares issued upon conversion of the Bridge Loan) and (y) the total number of shares of Nuvve Corp.’s common stock issuable upon exercise of Nuvve Options outstanding immediately prior to the closing. The “Closing Merger Consideration” was determined by taking $100,000,000, subtracting the amount of Nuvve Corp.’s indebtedness for borrowed money as of the closing of the Acquisition Merger (excluding Payroll Protection Program loans eligible for forgiveness – see Note 11 ), which was zero, and adding the aggregate exercise price of the Nuvve Options outstanding as of the date of the Merger Agreement or granted prior to the closing of the Acquisition Merger, which was $4,265,785. Additionally, the former stockholders of Nuvve Corp. would have been entitled to receive up to 4.0 million earn-out shares of the Company’s common stock if, for the year ending December 31, 2021, the Company’s revenue equaled or exceeded $30,000,000. The former Nuvve Corp. stockholders would have been entitled to a portion of the earn-out shares only if they continued to hold their shares of the Company’s common stock received in the Acquisition Merger through the earn-out payment date. As the Company's target revenue of $30,000,000 for the year ending December 31, 2021, was not met, the former stockholders of Nuvve Corp. were not entitled to receive up to the 4.0 million earn-out shares of the Company’s common stock. Pursuant to a purchase and option agreement, dated as of November 11, 2020 (the “Purchase and Option Agreement”), between the Company and EDF Renewables, Inc. (“EDF Renewables”), a former stockholder of Nuvve Corp. and the owner of more than 5% of the Company’s common stock, immediately after the closing, the Company repurchased 600,000 shares of the Company’s common stock from EDF Renewables at a price of $10.00 per share. In addition, on the Closing Date, EDF Renewables exercised its option to sell an additional $2,000,000 of shares of the Company’s common stock back to the Company at a price per share of $14.87 (the average closing price over the five preceding trading days). The share repurchase was completed on April 26, 2021 (see Note 12 ). As agreed between the parties to the Merger Agreement, immediately following the closing of the Acquisition Merger, the Company’s board of directors consisted of seven directors, five of whom were designated by Nuvve and two of whom were designated by Newborn. A majority of the directors qualified as independent directors under rules of Nasdaq. In Newborn’s initial public offering, Newborn issued 5,750,000 units at $10.00 per unit. Each unit issued in the initial public offering consisted of one ordinary share, one warrant to purchase one-half of an ordinary share (the “Public Warrant”), and one right automatically convertible into one-tenth of an ordinary upon completion of an initial business combination. Concurrently with the initial public offering, Newborn sold to its sponsor 272,500 units at $10.00 per unit in a private placement. Each unit in the private placement consisted of one ordinary share, one warrant to purchase one-half of an ordinary share (the “Private Warrant”), and one right automatically convertible into one-tenth of an ordinary share upon completion of an initial business combination. Newborn received net proceeds of approximately $57,989,380 from the public and private units. Upon closing of the initial public offering and the private placement, $57,500,000 was placed by Newborn in a trust account with Continental Stock Transfer & Trust Company acting as trustee (the “Trust Account”). On the Closing Date of the Business Combination, the balance in the Trust Account was $58,471,961. After the closing of the Business Combination, and other transactions described above, including payment of $18,630 for redemptions of ordinary shares by Newborn stockholders, payment of transaction costs of $3,702,421, repayment of loans made by Newborn’s sponsor to Newborn of $487,500, repurchase of $6,000,000 in common shares held by EDF Renewables, and transfer into an escrow account with Silicon Valley Bank of $495,000 to cover the balance of the Company’s PPP Loan payable ( Note 11 ), the Company received total net proceeds from the Trust Account in cash of $47,768,410. Also on March 19, 2021, the PIPE closed, and the Company received cash proceeds, net of $2,500 of transaction costs, of $14,247,500. (f) Emerging Growth Company Section 102(b)(1) of the Jumpstart Our Business Startups Act of 2012 (the “JOBS Act”) permits emerging growth companies (“EGC”) to delay complying with new or revised financial accounting standards that do not yet apply to 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). The Company qualifies as an EGC. The JOBS Act provides that an EGC can elect to opt-out of the extended transition period and comply with the requirements that apply to non-EGCs, but any such election to opt-out is irrevocable. The Company has elected not to opt-out of such an extended transition period, which means that when a standard is issued or revised and it has different application dates for public or private companies, the Company, as an EGC, can adopt the new or revised standard at the time private companies adopt the new or revised standard. This different adoption timing may make a comparison of the Company’s financial statements with another public company which is neither an EGC nor an EGC that has opted out of using the extended transition period difficult or impossible because of the potential differences in accounting standards used. (g) COVID-19 The novel coronavirus (COVID-19) which was declared a pandemic in March 2020, and the related restrictive measures such as travel restrictions, quarantines, and shutdowns, has negatively impacted the global economy. As national and local governments in different countries ease COVID-19 restrictions, and vaccines are distributed and rolled out successfully, we continue to see improved economic trends. However, COVID-19 and actions taken to mitigate its spread have had and are expected to continue to have an adverse impact on the economies and financial markets of many countries, including the geographical area in which the Company operates. The Company continues to monitor the situation closely but, at this time, is unable to predict the cumulative impact, both in terms of severity and duration, that the coronavirus pandemic has and will have on its business, operating results, cash flows and financial condition, and it could be material if the current circumstances continue to exist for a prolonged period of time. In addition to any direct impact on Nuvve’s business, it is reasonably possible that the estimates made by management in preparing Nuvve’s financial statements have been, or will be, materially and adversely impacted in the near term as a result of the COVID-19 outbreak. (h) Use of Estimates The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that may affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. Estimates and assumptions made by management include the impairment of intangible assets, estimated allowance for doubtful accounts receivable, the net realizable value of inventory, the grant date fair value of share-based payments, the fair value of notes payable conversion options, revenue recognition, the fair value of warrants, the fair value of the derivative liability - non-controlling redeemable preferred shares, realizability of the deferred financing costs, the recognition and disclosure of contingent liabilities. Management evaluates its estimates on an ongoing basis. Actual results could materially vary from those estimates. (i) Warrants The Company reviews the terms of warrants to purchase its common stock to determine whether warrants should be classified as liabilities or stockholders’ equity in its consolidated balance sheet. In order for a warrant to be classified in stockholders’ equity, the warrant must be (a) indexed to the Company’s equity and (b) meet the conditions for equity classification in Accounting Standards Codification (“ASC”) Subtopic 815-40, Derivatives and Hedging – Contracts in an Entity’s Own Equity . If a warrant does not meet the conditions for equity classification, it is carried on the consolidated balance sheet as a warrant liability measured at fair value, with subsequent changes in the fair value of the warrant recorded in the statement of operations as change in fair value of warrants in other income (expense). If a warrant meets both conditions for equity classification, the warrant is initially recorded in additional paid-in capital on the consolidated balance sheet, and the amount initially recorded is not subsequently remeasured at fair value. (j) Foreign Currency Matters For Nuvve Corp., Nuvve SaS, and Nuvve LTD, the functional currency is the U.S. dollar. All local foreign currency asset and liability amounts are remeasured into U.S. dollars at balance sheet date exchange rates, except for inventories, prepaid expenses, and property, plant, and equipment, which are remeasured at historical rates. Foreign currency income and expenses are remeasured at average exchange rates in effect during the year, except for expenses related to balance sheet amounts which are remeasured at historical exchange rates. Transaction gains and losses that arise from exchange rate fluctuations on transactions denominated in a currency other than the functional currency are included in other income (expense) in the consolidated statements of operations. The financial position and results of operations of the Company’s non-U.S. dollar functional currency subsidiary, Nuvve Denmark, are measured using the subsidiary’s local currency as the functional currency. The Company translates the assets and liabilities of Nuvve Denmark into U.S. dollars using exchange rates in effect at the balance sheet date. Revenues and expenses for the subsidiary are translated using rates that approximate those in effect during the period. The resulting translation gain and loss adjustments are reflected as a foreign currency translation adjustment in accumulated other comprehensive income (loss) within stockholders’ equity in the consolidated balance sheets. Foreign currency translation adjustments are included in other comprehensive income in the consolidated statements of operations and comprehensive loss. (k) Cash and Restricted Cash The Company maintains cash balances that can, at times, exceed amounts insured by the Federal Deposit Insurance Corporation, which is up to $250,000. The Company has not experienced any losses in these accounts and believes it is not exposed to any significant credit risk in this area. Pursuant to the Business Combination agreement, $495,000 of the proceeds received from Newborn’s trust account were required to be set aside in trust for the possible repayment of the Company’s Payroll Protection Plan (“PPP”) loan ( Note 11 ). The Company applied for forgiveness of the PPP loan. In June 2021, the PPP loan was fully forgiven and the $495,000 in trust was released to the Company. In May 2021, in connection with a new office lease agreement, the Company was required to provide an irrevocable, unconditional letter of credit in the amount of $380,000 to the landlord upon execution of the lease. This amount securing the letter of credit was recorded as restricted cash as of December 31, 2021. (l) Accounts Receivable Accounts receivable consist primarily of payments due from customers under the Company’s contracts with customers. The Company performs ongoing credit evaluations of customers to assess the probability of accounts receivable collection based on a number of factors, including past transaction experience with the customer, assessment of their credit history, and review of the invoicing terms of the contract. The Company maintains reserves for potential credit losses on customer accounts when deemed necessary. Based on the analysis the Compa ny recorded an allowance for doubtful accounts as o f December 31, 2021, but did not record an allowance for doubtful accounts for December 31, 2020. See Note 7 for details. (m) Concentrations of Credit Risk At December 31, 2021 and 2020, the financial instruments which potentially expose the Company to concentration of credit risk consist of cash in financial institutions (in excess of federally insured limits) and trade receivables. The Company had certain customers whose revenue individually represented 10% or more of the Company’s total revenue, or whose accounts receivable balances individually represented 10% or more of the Company’s total accounts receivable, as follows: For the years ended December 31, 2021 and 2020, one customer accounted for 12.4%, and four customers in aggregate accounted for 62.3% of revenue, respectively. During the years ended December 31, 2021 and 2020, the Company's top five customers accounted for approximately 44.0% and 70.8%, respectively, o f the Company’s total revenue. At December 31, 2021, two customers in aggregate accounted for 32.2% of accounts receivable. At December 31, 2020, four customers in aggregate accounted for 70.4% of accounts receivable. Approximately 56.0% and 80.0% of the Company’s trade accounts receivable balance was with five customers at December 31, 2021 and 2020, respectively. The Company estimates |
