Description of Organization and Business Operations
Description of Organization and Business Operations	NOTE 1. DESCRIPTION OF ORGANIZATION AND BUSINESS OPERATIONS ​ MCAP Acquisition Corporation (the “Company”) is a blank check company incorporated in Delaware on November 12, 2020. The Company was formed for the purpose of effectuating a merger, capital stock exchange, asset acquisition, stock purchase, reorganization or other similar business combination with one or more businesses (the “Business Combination”). The Company is an early stage and emerging growth company and, as such, the Company is subject to all of the risks associated with early stage and emerging growth companies. ​ All activity for the period November 12, 2020 (inception) through March 2, 2021 relates to the Company’s formation and the initial public offering (the “Initial Public Offering”), which is described in Note 3. ​ The registration statement for the Company’s Initial Public Offering was declared effective on February 25, 2021. On March 2, 2021, the Company consummated the Initial Public Offering of 31,625,000 units (“Units” and, with respect to the shares of Class A common stock included in the Units offered, the “Public Shares”), generating gross proceeds of $316,250,000 , which is described in Note 3. ​ Simultaneously with the closing of the Initial Public Offering, the Company consummated the sale of 5,983,333 private placement warrants (the “Private Placement Warrants”) at a price of $1.50 per warrant in a private placement to MCAP Acquisition, LLC (the “Sponsor”), generating gross proceeds of $8,975,000 , which is described in Note 4. ​ Following the closing of the Initial Public Offering on March 2, 2021, an amount of $316,250,000 ( $10.00 per Unit) from the net proceeds of the sale of the Units in the Initial Public Offering and the Private Placement Warrants was placed in a trust account (“Trust Account”) which may be invested in U.S. government securities, within the meaning set forth in Section 2(a)(16) of the Investment Company Act of 1940, as amended (the “Investment Company Act”), with a maturity of 185 days or less or in any open-ended investment company that holds itself out as a money market fund meeting the conditions of Rule 2a-7 of the Investment Company Act, as determined by the Company, until the earlier of: (i) the consummation of a Business Combination or (ii) the distribution of the Trust Account to the Company’s stockholders, as described below. ​ Transaction costs amounted to $17,853,629 consisting of $6,325,000 of underwriting fees, $11,068,750 of deferred underwriting fees (see Note 6) and $459,879 of other costs. In addition, $2,431,242 of cash was held outside of the Trust Account and is available for working capital purposes. ​ The Company’s management has broad discretion with respect to the specific application of the net proceeds of the Initial Public Offering and the sale of the Private Placement Warrants, although substantially all of the net proceeds are intended to be applied generally toward consummating a Business Combination. NASDAQ rules provide that the Business Combination must be with one or more target businesses that together have a fair market value equal to at least 80% of the balance in the Trust Account (as defined below) (less any deferred underwriting commissions and taxes payable on interest earned on the Trust Account) at the time of the signing of a definitive agreement to enter a Business Combination. The Company will only complete a Business Combination if the post-Business Combination company owns or acquires 50% or more of the outstanding voting securities of the target or otherwise acquires a controlling interest in the target sufficient for it not to be required to register as an investment company under the Investment Company Act. There is no assurance that the Company will be able to successfully effect a Business Combination. ​ The Company will provide its holders of the outstanding 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 either (i) in connection with a stockholder meeting called to approve the Business Combination or (ii) by means of a tender offer. In connection with a proposed Business Combination, the Company may seek stockholder approval of a Business Combination at a meeting called for such purpose at which stockholders may seek to redeem their shares, regardless of whether they vote for or against a Business Combination. The Company will proceed with a Business Combination only if the Company has net tangible assets of at least $5,000,001 either immediately prior to or upon such consummation of a Business Combination and, if the Company seeks stockholder approval, a majority of the outstanding shares voted are voted in favor of the Business Combination. ​ NOTE 1. DESCRIPTION OF ORGANIZATION AND BUSINESS OPERATIONS (cont.) ​ If the Company seeks stockholder approval of a Business Combination and it does not conduct redemptions pursuant to the tender offer rules, the Company’s Amended and Restated Certificate of Incorporation provides that a public stockholder, together with any affiliate of such stockholder or any other person with whom such stockholder is acting in concert or as a “group” (as defined under Section 13 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”)), will be restricted from seeking redemption rights with respect to 15% or more of the Public Shares without the Company’s prior written consent. ​ The public stockholders will be entitled to redeem their shares for a pro rata portion of the amount then in the Trust Account (initially $10.00 per 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 amount to be distributed to stockholders who redeem their shares will not be reduced by the deferred underwriting commissions the Company will pay to the underwriter (as discussed in Note 6). There will be no redemption rights upon the completion of a Business Combination with respect to the Company’s warrants. These shares of Class A common stock will be recorded at a redemption value and classified as temporary equity upon the completion of the Initial Public Offering, in accordance with Accounting Standards Codification (“ASC”) Topic 480 “Distinguishing Liabilities from Equity.” ​ If a stockholder vote is not required and the Company does not decide to hold a stockholder vote for business or other legal reasons, the Company will, pursuant to its Amended and Restated Certificate of Incorporation, offer such redemption pursuant to the tender offer rules of the Securities and Exchange Commission (the “SEC”), and file tender offer documents containing substantially the same information as would be included in a proxy statement with the SEC prior to completing a Business Combination. ​ The Company’s Sponsor has agreed (a) to vote its Founder Shares (as defined in Note 5) and any Public Shares purchased during or after the Initial Public Offering in favor of a Business Combination, (b) not to propose an amendment to the Company’s Amended and Restated Certificate of Incorporation with respect to the Company’s pre-Business Combination activities prior to the consummation of a Business Combination unless the Company provides dissenting public stockholders with the opportunity to redeem their Public Shares in conjunction with any such amendment; (c) not to redeem any shares (including the Founder Shares) and Private Placement Warrants into the right to receive cash from the Trust Account in connection with a stockholder vote to approve a Business Combination (or to sell any shares in a tender offer in connection with a Business Combination if the Company does not seek stockholder approval in connection therewith) or a vote to amend the provisions of the Amended and Restated Certificate of Incorporation relating to stockholders’ rights of pre-Business Combination activity and (d) that the Founder Shares and Private Placement Warrants shall not participate in any liquidating distributions upon winding up if a Business Combination is not consummated. However, the Sponsor will be entitled to liquidating distributions from the Trust Account with respect to any Public Shares purchased during or after the Initial Public Offering if the Company fails to complete its Business Combination. ​ The Company will have until March 2, 2023 to consummate a Business Combination. If the Company is unable to complete a Business Combination within 24 months from the closing of the Initial Public Offering (the “Combination Period”), the Company will (i) cease all operations except for the purpose of winding up, (ii) as promptly as reasonably possible but no more than ten business days thereafter, redeem the public shares, at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account, including interest earned on the funds held in the Trust Account and not previously released to the Company to pay taxes (less up to $100,000 of interest to pay dissolution expenses), divided by the number of then outstanding public shares, which redemption will completely extinguish public stockholders’ rights as stockholders (including the right to receive further liquidation distributions, if any), subject to applicable law, and (iii) as promptly as reasonably possible following such redemption, subject to the approval of the remaining stockholders and the Company’s board of directors, proceed to commence a voluntary liquidation and thereby a formal dissolution of the Company, subject in each case to its obligations under Delaware law to provide for claims of creditors and the requirements of applicable law. The underwriter has agreed to waive its rights to the deferred underwriting commission held in the Trust Account in the event the Company does not complete a Business Combination within the Combination Period and, in such event, such amounts will be included with the funds held in the Trust Account that will be available to fund the redemption of the Public Shares. In the event of such distribution, it is possible that the per share value of the assets remaining available for distribution will be less than the Initial Public Offering price per Unit ( $10.00 ). There will be no redemption rights or liquidating distributions with respect to the Founder Shares (as defined below) or the Private Placement Warrants, which will expire worthless if the Company fails to complete a Business Combination within the 24 -month time period. NOTE 1. DESCRIPTION OF ORGANIZATION AND BUSINESS OPERATIONS (cont.) ​ The Sponsor has agreed that it will be liable to the Company if and to the extent any claims by a third party for services rendered or products sold to the Company, or a prospective target business with which the Company has entered into a written letter of intent, confidentiality or similar agreement or Business Combination agreement, reduce the amount of funds in the Trust Account to below the lesser of (i) $10.00 per Public Share and (ii) the actual amount per Public Share held in the Trust Account as of the day of liquidation of the Trust Account, if less than $10.00 per share due to reductions in the value of the trust assets, less taxes payable, provided that such liability will not apply to any claims by a third party or prospective target business who executed a waiver of any and all rights to monies held in the Trust Account (whether or not such waiver is enforceable) nor will it apply to any claims under the Company’s indemnity of the underwriter of Initial Public Offering against certain liabilities, including liabilities under the Securities Act of 1933, as amended (the “Securities Act”). However, the Company has not asked the Sponsor to reserve for such indemnification obligations, nor has the Company independently verified whether the Sponsor has sufficient funds to satisfy its indemnity obligations and believe that the Sponsor’s only assets are securities of the Company. Therefore, the Company cannot assure its stockholders that the Sponsor would be able to satisfy those obligations. None of the Company’s officers or directors will indemnify the Company for claims by third parties including, without limitation, claims by vendors and prospective target businesses. The Company will seek to reduce the possibility that the Sponsor will have to indemnify the Trust Account due to claims of creditors by endeavoring to have all vendors, service providers, prospective target businesses or other entities with which the Company does business, execute agreements with the Company waiving any right, title, interest or claim of any kind in or to monies held in the Trust Account. ​ Management is currently evaluating the impact of the COVID-19 pandemic and has concluded that while it is reasonably possible that the virus could have a negative effect on the Company’s financial position, results of its operations and/or search for a target company, the specific impact is not readily determinable as of the date of the financial statement. The financial statement does not include any adjustments that might result from the outcome of this uncertainty. ​ Going Concern and Management’s Plans ​ The accompanying financial statement has been prepared on a going concern basis, which contemplates the realization of assets and the satisfaction of liabilities in the normal course of business. The Company’s management believes that its operations may not be sufficient to fund operating cash needs for at least 12 months from the issuance of this financial statement. The Company has no significant assets and has no revenue generating operations. There can be no assurance that the Company will be able to raise additional capital when needed, or at terms deemed acceptable, if at all. These factors raise substantial doubt about the Company’s ability to continue as a going concern for at least 12 months from the issuance of this financial statement. The accompanying financial statement does not include any adjustments relating to the recoverability and classification of asset carrying amounts or the amount and classification of liabilities that might result should the Company be unable to continue as a going concern. ​	MCAP ACQUISITION CORPORATION NOTES TO FINANCIAL STATEMENTS NOTE 1. DESCRIPTION OF ORGANIZATION AND BUSINESS OPERATIONS MCAP Acquisition Corporation (the “Company”) is a blank check company incorporated in Delaware on November 12, 2020. The Company was formed for the purpose of effectuating a merger, capital stock exchange, asset acquisition, stock purchase, reorganization or other similar business combination with one or more businesses (the “Business Combination”).The Company is an early stage and emerging growth company and, as such, the Company is subject to all of the risks associated with early stage and emerging growth companies. As of December 31, 2020, the Company had not yet commenced any operations. All activity for the period November 12, 2020 (inception) through December 31, 2020 relates to the Company’s formation and the proposed initial public offering (the “Proposed Offering”). The Company has selected December 31 as its fiscal year end. The Company’s ability to commence operations is contingent upon obtaining adequate financial resources through a proposed initial public offering of 27,500,000 units at $10.00 per unit (or 31,625,000 units if the underwriter’s over-allotment option is exercised in full) (the “Units” and, with respect to the shares of Class A common stock included in the Units being offered, the “Public Shares”) which is discussed in Note 3 and the sale of 5,433,333 warrants (or 5,983,333 warrants if the underwriter’s over-allotment option is exercised in full) (the “Private Placement Warrants”) at a price of $1.50 per Private Placement Warrant that will close in a private placement to MCAP Acquisition, LLC (the “Sponsor”) simultaneously with the closing of the Proposed Offering (see Note 4). The Company’s management has broad discretion with respect to the specific application of the net proceeds of the Proposed Offering and the sale of the Private Placement Warrants, although substantially all of the net proceeds are intended to be applied generally toward consummating a Business Combination. NASDAQ rules provide that the Business Combination must be with one or more target businesses that together have a fair market value equal to at least 80% of the balance in the Trust Account (as defined below) (less any deferred underwriting commissions and taxes payable on interest earned on the Trust Account) at the time of the signing a definitive agreement to enter a Business Combination. The Company will only complete a Business Combination if the post-Business Combination company owns or acquires 50% or more of the outstanding voting securities of the target or otherwise acquires a controlling interest in the target sufficient for it not to be required to register as an investment company under the Investment Company Act of 1940, as amended (the “Investment Company Act”). There is no assurance that the Company will be able to successfully effect a Business Combination. Upon the closing of the Proposed Offering, management has agreed that $10.00 per Unit sold in the Proposed Offering, including the proceeds from the sale of the Private Placement Warrants, will be held in a trust account (the “Trust Account”) and invested in U.S. government securities, within the meaning set forth in Section 2(a)(16) of the Investment Company Act, with a maturity of 185 days or less, or in any open-ended investment company that holds itself out as a money market fund meeting the conditions of Rule 2a-7 of the Investment Company Act, as determined by the Company, until the earlier of: (i) the consummation of a Business Combination or (ii) the distribution of the funds in the Trust Account to the Company’s stockholders, as described below. The Company will provide its holders of the outstanding 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 either (i) in connection with a stockholder meeting called to approve the Business Combination or (ii) by means of a tender offer. In connection with a proposed Business Combination, the Company may seek stockholder approval of a Business Combination at a meeting called for such purpose at which stockholders may seek to redeem their shares, regardless of whether they vote for or against a Business Combination. The Company will proceed with a Business Combination only if the Company has net tangible assets of at least $5,000,001 either immediately prior to or upon such consummation of a Business Combination and, if the Company seeks stockholder approval, a majority of the outstanding shares voted are voted in favor of the Business Combination. If the Company seeks stockholder approval of a Business Combination and it does not conduct redemptions pursuant to the tender offer rules, the Company’s Certificate of Incorporation provides that, a public stockholder, together with any affiliate of such stockholder or any other person with whom such stockholder is acting in concert or as a “group” (as defined under Section 13 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”)), will be restricted from seeking redemption rights with respect to 15% or more of the Public Shares without the Company’s prior written consent. The public stockholders will be entitled to redeem their shares for a pro rata portion of the amount then in the Trust Account (initially $10.00 per 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 amount to be distributed to stockholders who redeem their shares will not be reduced by the deferred underwriting commissions the Company will pay to the underwriter (as discussed in Note 7). There will be no redemption rights upon the completion of a Business Combination with respect to the Company’s warrants. These shares of Class A common stock will be recorded at a redemption value and classified as temporary equity upon the completion of the Proposed Offering, in accordance with Accounting Standards Codification (“ASC”) Topic 480 “Distinguishing Liabilities from Equity.” If a stockholder vote is not required and the Company does not decide to hold a stockholder vote for business or other legal reasons, the Company will, pursuant to its Certificate of Incorporation, offer such redemption pursuant to the tender offer rules of the Securities and Exchange Commission (the “SEC”), and file tender offer documents containing substantially the same information as would be included in a proxy statement with the SEC prior to completing a Business Combination. The Company’s Sponsor has agreed (a) to vote its Founder Shares (as defined in Note 5) and any Public Shares purchased during or after the Proposed Offering in favor of a Business Combination, (b) not to propose an amendment to the Company’s Certificate of Incorporation with respect to the Company’s pre-Business Combination activities prior to the consummation of a Business Combination unless the Company provides dissenting public stockholders with the opportunity to redeem their Public Shares in conjunction with any such amendment; (c) not to redeem any shares (including the Founder Shares) into the right to receive cash from the Trust Account in connection with a stockholder vote to approve a Business Combination (or to sell any shares in a tender offer in connection with a Business Combination if the Company does not seek stockholder approval in connection therewith) or a vote to amend the provisions of the Amended and Restated Certificate of Incorporation relating to stockholders’ rights of pre-Business Combination activity and (d) that the Founder Shares shall not participate in any liquidating distributions upon winding up if a Business Combination is not consummated. However, the Sponsor will be entitled to liquidating distributions from the Trust Account with respect to any Public Shares purchased during or after the Proposed Offering if the Company fails to complete its Business Combination. If the Company is unable to complete a Business Combination within 24 months from the closing of the Proposed Offering (the “Combination Period”), the Company will (i) cease all operations except for the purpose of winding up, (ii) as promptly as reasonably possible but no more than ten The Sponsor has agreed that it will be liable to the Company if and to the extent any claims by a third party for services rendered or products sold to the Company, or a prospective target business with which the Company has entered into a written letter of intent, confidentiality or similar agreement or Business Combination agreement, reduce the amount of funds in the Trust Account to below the lesser of (i) $10.00 per Public Share and (ii) the actual amount per Public Share held in the Trust Account as of the day of liquidation of the Trust Account, if less than $10.00 per share due to reductions in the value of the trust assets, less taxes payable, provided that such liability will not apply to any claims by a third party or prospective target business who executed a waiver of any and all rights to monies held in the Trust Account (whether or not such waiver is enforceable) nor will it apply to any claims under the Company’s indemnity of the underwriter of Proposed Offering against certain liabilities, including liabilities under the Securities Act of 1933, as amended (the “Securities Act”). However, the Company has not asked the Sponsor to reserve for such indemnification obligations, nor has the Company independently verified whether the Sponsor has sufficient funds to satisfy its indemnity obligations and believe that the Sponsor’s only assets are securities of the Company. Therefore, the Company cannot assure its stockholders that the Sponsor would be able to satisfy those obligations. None of the Company’s officers or directors will indemnify the Company for claims by third parties including, without limitation, claims by vendors and prospective target businesses. The Company will seek to reduce the possibility that the Sponsor will have to indemnify the Trust Account due to claims of creditors by endeavoring to have all vendors, service providers, prospective target businesses or other entities with which the Company does business, execute agreements with the Company waiving any right, title, interest or claim of any kind in or to monies held in the Trust Account. Going Concern Consideration At December 31, 2020, the Company had $25,000 in cash and working capital deficit of $140,584. The Company has incurred and expects to continue to incur significant costs in pursuit of its financing and acquisition plans. These conditions raise substantial doubt about the Company’s ability to continue as a going concern for a period of time within one year after the date that the financial statements are issued. Management plans to address this uncertainty through the Proposed Offering as discussed in Note 3. There is no assurance that the Company’s plans to raise capital or to consummate a Business Combination will be successful or successful within the Combination Period. The financial statements do not include any adjustments that might result from the outcome of this uncertainty.	Note 1 — Description of Organization and Business Operations MCAP Acquisition Corporation (the “Company”) is a blank check company incorporated in Delaware on November 12, 2020. The Company was formed for the purpose of effectuating a merger, capital stock exchange, asset acquisition, stock purchase, reorganization or other similar business combination with one or more businesses (the “Business Combination”). The Company is an early stage and emerging growth company and, as such, the Company is subject to all of the risks associated with early stage and emerging growth companies. The accompanying condensed consolidated financial statements includes the Company and its wholly owned subsidiaries GRNT Merger Sub 1 LLC, GRNT Merger Sub 2 LLC, GRNT Merger Sub 3 LLC, and GRNT Merger Sub 4 LLC. As of September 30, 2021, the Company had not yet commenced any operations. All activity for the period November 12, 2020 (inception) through September 30, 2021 relates to the Company’s formation, initial public offering (the “Initial Public Offering”) and search to effectuate a Business Combination. The Company has selected December 31 as its fiscal year end. The registration statement for the Company’s Initial Public Offering was declared effective on February 25, 2021. On March 2, 2021, the Company consummated the Initial Public Offering of 31,625,000 units (“Units” and, with respect to the shares of Class A common stock included in the Units offered, the “Public Shares”), generating gross proceeds of $316,250,000, which is described in Note 3. Simultaneously with the closing of the Initial Public Offering, the Company consummated the sale of 5,983,333 private placement warrants (the “Private Placement Warrants”) at a price of $1.50 per warrant in a private placement to MCAP Acquisition, LLC (the “Sponsor”), generating gross proceeds of $8,975,000, which is described in Note 4. Following the closing of the Initial Public Offering on March 2, 2021, an amount of $316,250,000 ($10.00 per Unit) from the net proceeds of the sale of the Units in the Initial Public Offering and the Private Placement Warrants was placed in a trust account (“Trust Account”) which may be invested in U.S. government securities, within the meaning set forth in Section 2(a)(16) of the Investment Company Act of 1940, as amended (the “Investment Company Act”), with a maturity of 185 days or less or in any open-ended investment company that holds itself out as a money market fund meeting the conditions of Rule 2a-7 of the Investment Company Act, as determined by the Company, until the earlier of: (i) the consummation of a Business Combination or (ii) the distribution of the Trust Account to the Company’s stockholders, as described below. Transaction costs of the Initial Public Offering amounted to $17,853,629 consisting of $6,325,000 of underwriting fees, $11,068,750 of deferred underwriting fees (see Note 6) and $459,879 of other costs. Following the closing of the Initial Public Offering $2,431,242 of cash was held outside of the Trust Account available for working capital purposes. As of September 30, 2021, we have available to us $797,602 of cash on our balance sheet and a working capital surplus of $706,131. The Company’s management has broad discretion with respect to the specific application of the net proceeds of the Initial Public Offering and the sale of the Private Placement Warrants, although substantially all of the net proceeds are intended to be applied generally toward consummating a Business Combination. NASDAQ rules provide that the Business Combination must be with one or more target businesses that together have a fair market value equal to at least 80% of the balance in the Trust Account (as defined below) (less any deferred underwriting commissions and taxes payable on interest earned on the Trust Account) at the time of the signing of a definitive agreement to enter a Business Combination. The Company will only complete a Business Combination if the post-Business Combination company owns or acquires 50% or more of the outstanding voting securities of the target or otherwise acquires a controlling interest in the target sufficient for it not to be required to register as an investment company under the Investment Company Act. There is no assurance that the Company will be able to successfully effect a Business Combination. ​ Note 1 — Description of Organization and Business Operations (continued) The Company will provide its holders of the outstanding 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 either (i) in connection with a stockholder meeting called to approve the Business Combination or (ii) by means of a tender offer. In connection with a proposed Business Combination, the Company may seek stockholder approval of a Business Combination at a meeting called for such purpose at which stockholders may seek to redeem their shares, regardless of whether they vote for or against a Business Combination. The Company will proceed with a Business Combination only if the Company has net tangible assets of at least $5,000,001 either immediately prior to or upon such consummation of a Business Combination and, if the Company seeks stockholder approval, a majority of the outstanding shares voted are voted in favor of the Business Combination. The Company will have until March 2, 2023 to consummate a Business Combination. If the Company is unable to complete a Business Combination within 24 months from the closing of the Initial Public Offering (the “Combination Period”), the Company will (i) cease all operations except for the purpose of winding up, (ii) as promptly as reasonably possible but no more than ten The Sponsor has agreed that it will be liable to the Company if and to the extent any claims by a third party for services rendered or products sold to the Company, or a prospective target business with which the Company has entered into a written letter of intent, confidentiality or similar agreement or Business Combination agreement, reduce the amount of funds in the Trust Account to below the lesser of (i) $10.00 per Public Share and (ii) the actual amount per Public Share held in the Trust Account as of the day of liquidation of the Trust Account, if less than $10.00 per share due to reductions in the value of the trust assets, less taxes payable, provided that such liability will not apply to any claims by a third party or prospective target business who executed a waiver of any and all rights to monies held in the Trust Account (whether or not such waiver is enforceable) nor will it apply to any claims under the Company’s indemnity of the underwriter of Initial Public Offering against certain liabilities, including liabilities under the Securities Act of 1933, as amended (the “Securities Act”). However, the Company has not asked the Sponsor to reserve for such indemnification obligations, nor has the Company independently verified whether the Sponsor has sufficient funds to satisfy its indemnity obligations and believe that the Sponsor’s only assets are securities of the Company. Therefore, the Company cannot assure its stockholders that the Sponsor would be able to satisfy those obligations. None of the Company’s officers or directors will indemnify the Company for claims by third parties including, without limitation, claims by vendors and prospective target businesses. The Company will seek to reduce the possibility that the Sponsor will have to indemnify the Trust Account due to claims of creditors by endeavoring to have all vendors, service providers, prospective target businesses or other entities with which the Company does business, execute agreements with the Company waiving any right, title, interest or claim of any kind in or to monies held in the Trust Account. ​ Note 1 — Description of Organization and Business Operations (continued) Going Concern and Management’s Plans The accompanying unaudited condensed consolidated financial statements have been prepared on a going concern basis, which contemplates the realization of assets and the satisfaction of liabilities in the normal course of business. As of September 30, 2021, we had incurred accumulated losses of approximately $2,915,213 for the period from November 12, 2020 (date of inception) through September 30, 2021. The Company’s management believes that its operations may not be sufficient to fund operating cash needs for at least 12 months from the issuance of these financial statements. The Company has no significant assets and has no revenue generating operations. There can be no assurance however that the Company will be able to raise additional capital when needed, or at terms deemed acceptable, if at all. These factors raise substantial doubt about the company’s ability to continue as a going concern within one year after the date that the unaudited condensed financial statements are issued. The unaudited condensed consolidated financial statements do not include any adjustments relating to the recoverability and classification of asset carrying amounts or the amount and classification of liabilities that might result should the Company be unable to continue as a going concern. Risks and Uncertainties Management is currently evaluating the impact of the COVID-19 pandemic and has concluded that while it is reasonably possible that the virus could have a negative effect on the Company’s financial position, results of its operations and/or search for a target company, the specific impact is not readily determinable as of the date of the financial statement. The financial statements do not include any adjustments that might result from the outcome of this uncertainty.

Summary of Significant Accounting Policies
Summary of Significant Accounting Policies	NOTE 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES ​ Basis of Presentation ​ The accompanying balance sheet has been prepared in conformity with accounting principles generally accepted in the United States of America (“GAAP”) and pursuant to the rules and regulations of the SEC. ​ 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 independent registered public accounting firm attestation requirements of Section 404 of the Sarbanes-Oxley Act, 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. ​ NOTE 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (cont.) ​ 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 a company can elect to opt out of the extended transition period and comply with the requirements that apply to non-emerging growth companies but any such election to opt out is irrevocable. The Company has elected not to opt out of such 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 emerging growth company, can adopt the new or revised standard at the time private companies adopt the new or revised standard. This may make comparison of the Company’s financial statements with another public company, which is neither an emerging growth company nor an emerging growth company which has opted out of using the extended transition period difficult or impossible because of the potential differences in accounting standards used. ​ Use of Estimates ​ The preparation of the balance sheet 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 financial statements and the reported amounts of revenues and 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 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 highly liquid investments purchased with an original maturity of three months or less to be cash equivalents. Cash equivalents are carried at cost, which approximates fair value. The Company had $2,431,242 in cash and no cash equivalents as of March 2, 2021. ​ 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 recognizes accrued interest and penalties related to unrecognized tax benefits, if any, as income tax expense. There were no unrecognized tax benefits and no amounts accrued for interest and penalties as of March 2, 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. ​ NOTE 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (cont.) ​ Class A Common Stock Subject to Possible Redemption ​ The Company accounts for its shares subject to possible redemption in accordance with the guidance in Accounting Standards Codification (“ASC”) Topic 480 “Distinguishing Liabilities from Equity.” Shares subject to mandatory redemption (if any) is classified as a liability instrument and is measured at fair value. Conditionally redeemable shares of common stock (including shares of common stock that feature redemption rights that are 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, shares are classified as stockholders’ equity. The Company’s shares feature certain redemption rights that are considered to be outside of the Company’s control and subject to occurrence of uncertain future events. Accordingly, at March 2, 2021, shares subject to possible redemption are presented as temporary equity, outside of the stockholders’ equity section of the Company’s balance sheet. ​ Offering Costs ​ Offering costs consist of legal, accounting, underwriting fees and other costs incurred through the balance sheet date that are directly related to the Initial Public Offering. Offering costs amounting to $17,853,629 were charged to stockholders’ equity upon the completion of the Initial Public Offering. ​ Cash Held in Trust Account ​ At March 2, 2021, the assets held in the Trust Account were held in cash. ​ Concentration 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 Depository Insurance Corporation coverage limit of $250,000 . The Company has not experienced losses on this account and management believes the Company is not exposed to significant risks on such account. ​ Fair Value of Financial Instruments ​ The fair value of the Company’s assets and liabilities, which qualify as financial instruments under ASC Topic 820, “Fair Value Measurement,” approximates the carrying amounts represented in the accompanying balance sheet, primarily due to their short-term nature. ​ Derivative Financial Instruments The Company evaluates its financial instruments to determine if such instruments are derivatives or contain features that qualify as embedded derivatives in accordance with ASC Topic 815, “Derivatives and Hedging”. For derivative financial instruments that are accounted for as liabilities, the derivative instrument is initially recorded at its fair value on the grant date and is then re-valued at each reporting date, with changes in the fair value reported in the statements of operations. The classification of derivative instruments, including whether such instruments should be recorded as liabilities or as equity, is evaluated at the end of each reporting period. Derivative liabilities are classified in the balance sheet as current or non-current based on whether or not net-cash settlement or conversion of the instrument could be required within 12 months of the balance sheet date. ​ Recently Issued Accounting Standards ​ 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 financial statements. ​	NOTE 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Basis of Presentation The accompanying 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. 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 independent registered public accounting firm attestation requirements of Section 404 of the Sarbanes-Oxley Act, 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 a company can elect to opt out of the extended transition period and comply with the requirements that apply to non-emerging growth companies but any such election to opt out is irrevocable. The Company has elected not to opt out of such 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 emerging growth company, can adopt the new or revised standard at the time private companies adopt the new or revised standard. This may make comparison of the Company’s financial statements with another public company, which is neither an emerging growth company nor an emerging growth company which has opted out of using the extended transition period difficult or impossible because of the potential differences in accounting standards used. Use of Estimates The preparation of 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 financial statements and the reported amounts of revenue and 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 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 did not have any cash equivalents as of December 31, 2020. 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 recognizes accrued interest and penalties related to unrecognized tax benefits, if any, as income tax expense. There were no unrecognized tax benefits and no amounts accrued for interest and penalties as of December 31, 2020. 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 provision for income taxes was deemed to be immaterial for the period from November 12, 2020 (inception) through December 31, 2020. Net Loss Per Common Share Net loss per share of common stock is computed by dividing net loss by the weighted average number of common shares outstanding during the period, excluding common shares subject to forfeiture. Weighted average shares were reduced for the effect of an aggregate of 1,031,250 shares of Class B common stock that are subject to forfeiture if the over-allotment option is not exercised by the underwriter (see Notes 7 and 8). At December 31, 2020, 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. As a result, diluted loss per share is the same as basic loss per share for the period presented. Concentration 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 Depository Insurance Corporation coverage limit of $250,000. The Company has not experienced losses on this account and management believes the Company is not exposed to significant risks on such account. Fair Value of Financial Instruments The fair value of the Company’s assets and liabilities, which qualify as financial instruments under ASC Topic 820, “Fair Value Measurement,” approximates the carrying amounts represented in the accompanying balance sheet, primarily due to their short-term nature. Recently Issued Accounting Standards 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 financial statements. Subsequent Events Management of the Company evaluates events that have occurred after the balance sheet date of December 31, 2020 through the date these financial statements were issued. Based upon the review, management did not identify any recognized or non-recognized subsequent events that would have required adjustment or disclosure in the financial statements, except as follows. On February 25, 2021, the Company’s Board of Directors approved a stock dividend of 718,750 shares of Class B common stock (the “Stock Dividend”). The par values of the common and preferred stock were not adjusted as a result of the Stock Dividend. All references to common stock, warrants to purchase common stock, share data, per share data, and related information contained in the financial statements have been retroactively adjusted to reflect this Stock Dividend for all periods presented.	Note 2 — Summary of Significant Accounting Policies Basis of Presentation The accompanying financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“US GAAP”) and pursuant to the accounting and disclosure rules and regulations of the U.S. Securities and Exchange Commission. In preparation of the Company’s unaudited condensed consolidated financial statements as of and for quarterly period ended September 30, 2021, the Company concluded it will restate its financial statements to classify all Class A common shares as Class A common stock subject to possible redemption in temporary equity as of September 30, 2021 (see Note 11). 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 independent registered public accounting firm attestation requirements of Section 404 of the Sarbanes-Oxley Act, 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. ​ Note 2 — Summary of Significant Accounting Policies (continued) 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.

There were no unrecognized tax benefits and no amounts accrued for interest and penalties as of September 30, 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 provision for income taxes was deemed to be immaterial for the three and nine months ended September 30, 2021. ​ Note 2 — Summary of Significant Accounting Policies (continued) Class A Common Stock Subject to Possible Redemption The Company accounts for its shares subject to possible redemption in accordance with the guidance in Accounting Standards Codification (“ASC”) Topic 480 “Distinguishing Liabilities from Equity.” Shares subject to mandatory redemption (if any) is classified as a liability instrument and is measured at fair value. Conditionally redeemable shares of common stock (including shares of common stock that feature redemption rights that are 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, shares are classified as stockholders’ equity. The Company’s shares feature certain redemption rights that are considered to be outside of the Company’s control and subject to occurrence of uncertain future events. Accordingly, at September 30, 2021, 31,625,000 shares of Class A Common Stock subject to possible redemption are presented as temporary equity, outside of the stockholders’ equity section of the Company’s balance sheet. Cash Held in Trust Account At September 30, 2021, the assets held in the Trust Account were invested in a money market fund. Concentration 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 Depository Insurance Corporation coverage limit of $250,000. The Company has not experienced losses on this account and management believes the Company is not exposed to significant risks on such account. Net Loss Per Share The Company complies with accounting and disclosure requirements of FASB ASC Topic 260, Earnings Per Share. Net loss per share is computed by dividing net income by the weighted average number of shares of common stock outstanding during the period. The Company has two classes of shares, Class A common stock and Class B common stock. Earnings and losses are shared pro rata between the two classes of common stock. The Company has not considered the effect of warrants sold in the Initial Public Offering and the private placement to purchase common stock in the calculation of diluted income per share, since the exercise of the warrants is contingent upon the occurrence of future events. As a result, diluted net loss per common share is the same as basic net loss per share for the period presented. The Company’s condensed statement of operations applies the two-class method in calculating net income per share. Basic and diluted net loss per share for Class A common stock and Class B common stock is calculated by dividing net loss attributable to the Company by the weighted average number of shares of Class A common stock and Class B common stock outstanding, allocated proportionally to each class of common stock. ​ Note 2 — Summary of Significant Accounting Policies (continued) The following table reflects the calculation of basic and diluted net loss per ordinary share (in dollars, except per share amounts): ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ For the Three ​ For the ​ ​ Three Months Ended ​ Nine Months Ended ​ ​ September 30, ​ September 30, ​ 2021 2021 Class A common stock ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Net loss allocable to Class A common stock ​ $ (3,680,202) ​ $ (2,193,437) ​ ​ ​ ​ ​ ​ ​ Basic and diluted weighted ​ ​ 31,625,000 ​ ​ 24,674,451 Basic and diluted net ​ $ (0.12) ​ $ (0.09) Non-Redeemable Class B common stock ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Net loss allocable to Class B common stock ​ $ (920,051) ​ $ (702,826) ​ ​ ​ ​ ​ ​ ​ Basic and diluted weighted ​ ​ 7,906,250 ​ ​ 7,906,250 Basic and diluted net ​ $ (0.12) ​ $ (0.09) ​ Fair Value of Financial Instruments The fair value of the Company’s assets and liabilities, which qualify as financial instruments under ASC Topic 820, “Fair Value Measurement,” approximates the carrying amounts represented in the accompanying balance sheet, primarily due to their short-term nature.

The Public Warrants will expire five years from the consummation of a Business Combination or earlier upon redemption or liquidation. ​ The Company will not be obligated to deliver any Class A common stock pursuant to the exercise of a Public Warrant and will have no obligation to settle such Public Warrant exercise unless a registration statement under the Securities Act covering the issuance of the Class A common stock issuable upon exercise of the Public Warrants is then effective and a prospectus relating thereto is current, subject to the Company satisfying its obligations with respect to registration. No Public Warrant will be exercisable for cash or on a cashless basis, and the Company will not be obligated to issue any shares to holders seeking to exercise their Public Warrants, unless the issuance of the shares upon such exercise is registered or qualified under the securities laws of the state of the exercising holder, or an exemption from registration is available. ​ NOTE 7. WARRANT LIABILITY (cont.) ​ The Company has agreed that as soon as practicable, but in no event later than 15 business days after the closing of its initial Business Combination, it will use its best efforts to file with the SEC, and within 60 business days following its initial Business Combination to have declared effective, a registration statement covering the issuance of 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. If a registration statement covering the shares of Class A common stock issuable upon exercise of the warrants is not effective by the 60 th business day after the closing of a 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. ​ Once the Public Warrants become exercisable, the Company may redeem the Public Warrants for redemption: ​ ● in whole and not in part; ● at a price of $0.01 per Public Warrant; ● upon not less than 30 days’ prior written notice of redemption to each warrant holder; and ● if, and only if, the reported last sale price of the Class A common stock equals or exceeds $18.00 per share (as adjusted for stock splits, stock dividends, reorganizations, recapitalizations and the like and certain issuances of Class A common stock and equity-linked securities) for any 20 trading days within a 30 -trading day period commencing no earlier than the date the warrants become exercisable and ending on the third business day before the date on which the Company sends the notice of redemption to the warrant holders. ​ If and when the Public Warrants become redeemable by the Company, the Company may not exercise its redemption right if the issuance of shares of common stock upon exercise of the warrants is not exempt from registration or qualification under applicable state blue sky laws or the Company is unable to effect such registration or qualification. ​ The Company accounts for the 10,541,667 Public Warrants issued in connection with the Initial Public Offering and the 5,983,333 Private Placement Warrants in accordance with the guidance contained in ASC 815-40. Such guidance provides that because the warrants do not meet the criteria for equity treatment thereunder, each warrant must be recorded as a liability. The warrant agreement contains an Alternative Issuance provision that if less than 70% of the consideration receivable by the holders of the Class A common stock in the Business Combination is payable in the form of common equity in the successor entity, and if the holders of the warrants properly exercises the warrants within thirty days following the public disclosure of the consummation of Business Combination by the Company, the warrant price shall be reduced by an amount equal to the difference (but in no event less than zero) of (i) the warrant price in effect prior to such reduction minus (ii) (A) the Per Share Consideration (as defined below) minus (B) the Black-Scholes Warrant Value (as defined below). The “Black-Scholes Warrant Value” means the value of a Warrant immediately prior to the consummation of the Business Combination based on the Black-Scholes Warrant Model for a Capped American Call on Bloomberg Financial Markets. “Per Share Consideration” means (i) if the consideration paid to holders of the common stock consists exclusively of cash, the amount of such cash per common stock, and (ii) in all other cases, the volume weighted average price of the common stock as reported during the ten-trading day period ending on the trading day prior to the effective date of the Business Combination. ​ NOTE 7. WARRANT LIABILITY (cont.) ​ The Company believes that the adjustments to the exercise price of the warrants is based on a variable that is not an input to the fair value of a “fixed-for-fixed” option as defined under FASB ASC Topic No. 815 – 40, and thus the warrants are not eligible for an exception from derivative accounting. The accounting treatment of derivative financial instruments requires that the Company record a derivative liability upon the closing of the Initial Public Offering. Accordingly, the Company will classify each warrant as a liability at its fair value and the warrants will be allocated a portion of the proceeds from the issuance of the Units equal to its fair value determined by the Monte Carlo simulation. This liability is subject to re-measurement at each balance sheet date. With each such remeasurement, the warrant liability will be adjusted to fair value, with the change in fair value recognized in the Company’s statement of operations. The Company will reassess the classification at each balance sheet date. If the classification changes as a result of events during the period, the warrants will be reclassified as of the date of the event that causes the reclassification. ​ The Private Placement Warrants will be identical to the Public Warrants underlying the Units being sold in the Initial Public Offering, except that the Private Placement Warrants and the shares of common stock issuable upon the exercise of the Private Placement Warrants will not be transferable, assignable or salable until 30 days after the completion of a Business Combination, subject to certain limited exceptions. Additionally, the Private Placement Warrants will be exercisable on a cashless basis and will be non-redeemable so long as they are held by the initial purchasers or their permitted transferees (other than in the case the Public Warrants are redeemed for $0.10 as described above). If the Private Placement Warrants are held by someone other than the initial purchasers or their permitted transferees, the Private Placement Warrants will be redeemable by the Company and exercisable by such holders on the same basis as the Public Warrants. ​	Note 7 — Warrant Liability Public Warrants may only be exercised for a whole number of shares.

In the case that additional shares of Class A common stock, or equity linked securities, are issued or deemed issued in excess of the amounts offered in the Initial Public Offering and related to the closing of a Business Combination, the ratio at which shares of Class B common stock shall convert into shares of Class A common stock will be adjusted (unless the holders of a majority of the outstanding shares of Class B common stock agree to waive such adjustment with respect to any such issuance or deemed issuance) so that the number of shares of Class A common stock issuable upon conversion of all shares of Class B common stock will equal, in the aggregate, on an as converted basis, 20% of the sum of the total number of all shares of common stock outstanding upon the completion of the Initial Public Offering plus all shares of Class A common stock and equity linked securities issued or deemed issued in connection with a Business Combination (excluding any shares or equity linked securities issued, or to be issued, to any seller in a Business Combination, and any private placement-equivalent units and its underlying securities issued to the Sponsor or its affiliates upon conversion of loans made to the Company). NOTE 8. STOCKHOLDERS’ EQUITY (cont.) ​ The Company may issue additional common stock or preferred stock to complete its Business Combination or under an employee incentive plan after completion of its Business Combination. ​	NOTE 7. STOCKHOLDER’S EQUITY Preferred Stock outstanding Class A Common Stock outstanding Class B Common Stock outstanding The shares of Class B common stock will automatically convert into shares of Class A common stock at the time of the Business Combination on a one-for-one basis, subject to adjustment for stock splits, stock dividends, reorganizations, recapitalizations and the like. In the case that additional shares of Class A common stock, or equity linked securities, are issued or deemed issued in excess of the amounts offered in the Proposed Offering and related to the closing of a Business Combination, the ratio at which shares of Class B common stock shall convert into shares of Class A common stock will be adjusted (unless the holders of a majority of the outstanding shares of Class B common stock agree to waive such adjustment with respect to any such issuance or deemed issuance) so that the number of shares of Class A common stock issuable upon conversion of all shares of Class B common stock will equal, in the aggregate, on an as converted basis, 20% of the sum of the total number of all shares of common stock outstanding upon the completion of the Proposed Offering plus all shares of Class A common stock and equity linked securities issued or deemed issued in connection with a Business Combination (excluding any shares or equity linked securities issued, or to be issued, to any seller in a Business Combination, and any private placement-equivalent warrants issued to the Sponsor or its affiliates upon conversion of loans made to the Company). Holders of Founder Shares may also elect to convert their shares of Class B common stock into an equal number of shares of Class A common stock, subject to adjustment as provided above, at any time. The Company may issue additional common stock or preferred stock to complete its Business Combination or under an employee incentive plan after completion of its Business Combination. Warrants — The Company will not be obligated to deliver any Class A common stock pursuant to the exercise of a Public Warrant and will have no obligation to settle such Public Warrant exercise unless a registration statement under the Securities Act covering the issuance of the Class A common stock issuable upon exercise of the Public Warrants is then effective and a prospectus relating thereto is current, subject to the Company satisfying its obligations with respect to registration. No Public Warrant will be exercisable for cash or on a cashless basis, and the Company will not be obligated to issue any shares to holders seeking to exercise their Public Warrants, unless the issuance of the shares upon such exercise is registered or qualified under the securities laws of the state of the exercising holder, or an exemption from registration is available. The Company has agreed that as soon as practicable, but in no event later than 15 business days, after the closing of a Business Combination, it will use its best efforts to file with the SEC a registration statement registering the issuance, under the Securities Act, of the Class A common stock issuable upon exercise of the Public Warrants. The Company will use its best efforts to file with the SEC a registration statement covering the shares of Class A common stock issuable upon exercise of the warrants, to cause such registration statement to become effective 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 60 th 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. Once the Public Warrants become exercisable, the Company may redeem the Public Warrants for redemption: ● in whole and not in part; ● at a price of $0.01 per Public Warrant; ● upon not less than 30 days ’ prior written notice of redemption to each warrant holder and ● if, and only if, the reported last sale price of the Class A common stock equals or exceeds $18.00 per share (as adjusted for stock splits, stock dividends, reorganizations, recapitalizations and the like) for any 20 trading days within a 30 - trading day period ending three business days before the Company sends the notice of redemption to the warrant holders. If and when the Public Warrants become redeemable by the Company, the Company may not exercise its redemption right if the issuance of shares of common stock upon exercise of the warrants is not exempt from registration or qualification under applicable state blue sky laws or the Company is unable to effect such registration or qualification. The exercise price and number of shares of Class A common stock issuable upon exercise of the warrants may be adjusted in certain circumstances including in the event of a share dividend, or recapitalization, reorganization, merger or consolidation. Additionally, in no event will the Company be required to net cash settle the Public Warrants. 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. If the Company calls the Public Warrants for redemption, management will have the option to require all holders that wish to exercise the Public Warrants to do so on a “cashless basis,” as described in the warrant agreement. The exercise price and number of shares of common stock issuable upon exercise of the Public Warrants may be adjusted in certain circumstances including in the event of a stock dividend, extraordinary dividend or recapitalization, reorganization, merger or consolidation. 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 respect to such warrants. Accordingly, the warrants may expire worthless. 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 its initial Business Combination at an issue price or effective issue price of less than $9.20 per share of Class A common stock (with such issue price or effective issue price to be determined in good faith by the Company’s 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 than 60% of the total equity proceeds, and interest thereon, available for the funding of the Company’s initial Business Combination on the date of the consummation of such initial Business Combination (net of redemptions), and (z) the volume weighted average trading price of the Company’s 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 above will be adjusted (to the nearest cent) to be equal to 180% of the greater of the Market Value and the Newly Issued Price. The Private Placement Warrants will be identical to the Public Warrants included in the Units being sold in the Proposed Offering, except that the Private Placement Warrants will and the shares of common stock issuable upon the exercise of the Private Placement Warrants will not be transferable, assignable or salable until 30 days after the completion of a Business Combination, subject to certain limited exceptions. Additionally, the Private Placement Warrants will be exercisable on a cashless basis and will be non-redeemable so long as they are held by the initial purchasers or their permitted transferees. If the Private Placement Warrants are held by someone other than the initial purchasers or their permitted transferees, the Private Placement Warrants will be redeemable by the Company and exercisable by such holders on the same basis as the Public Warrants.	Note 8 – Stockholders’ Equity Preferred Stock outstanding Class A Common Stock issued outstanding Class B Common Stock — outstanding outstanding Holders of Class A common stock and Class B common stock will vote together as a single class on all other matters submitted to a vote of stockholders, except as required by law; provided that only holders of Class B common stock have the right to vote for the election of directors prior to the Company’s initial Business Combination. The shares of Class B common stock will automatically convert into shares of Class A common stock at the time of the Business Combination on a one-for-one basis, subject to adjustment for stock splits, stock dividends, reorganizations, recapitalizations and the like. In the case that additional shares of Class A common stock, or equity linked securities, are issued or deemed issued in excess of the amounts offered in the Initial Public Offering and related to the closing of a Business Combination, the ratio at which shares of Class B common stock shall convert into shares of Class A common stock will be adjusted (unless the holders of a majority of the outstanding shares of Class B common stock agree to waive such adjustment with respect to any such issuance or deemed issuance) so that the number of shares of Class A common stock issuable upon conversion of all shares of Class B common stock will equal, in the aggregate, on an as converted basis, 20% of the sum of the total number of all shares of common stock outstanding upon the completion of the Initial Public Offering plus all shares of Class A common stock and equity linked securities issued or deemed issued in connection with a Business Combination (excluding any shares or equity linked securities issued, or to be issued, to any seller in a Business Combination, and any private placement-equivalent units and its underlying securities issued to the Sponsor or its affiliates upon conversion of loans made to the Company). The Company may issue additional common stock or preferred stock to complete its Business Combination or under an employee incentive plan after completion of its Business Combination. ​

Fair Value Measurements

Fair Value Measurements	Mar. 02, 2021	Sep. 30, 2021
Fair Value Measurements
Fair Value Measurements	NOTE 9. FAIR VALUE MEASUREMENTS ​ The Company follows the guidance in ASC 820 for its financial assets and liabilities that are re-measured and reported at fair value at each reporting period, and non-financial assets and liabilities that are re-measured and reported at fair value at least annually. 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 (unadjusted) 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. ​ ​ ​ ​ ​ Level March 2, 2021 Assets: ​ ​ ​ ​ Cash and marketable securities held in Trust Account ​ 1 ​ $ 316,250,000 ​ ​ ​ ​ ​ Liabilities: ​ ​ ​ ​ Public Warrants ​ 3 ​ $ 14,442,083 ​ Private Placement Warrants ​ 3 ​ $ 8,376,666 ​ ​ The Warrants were accounted for as liabilities in accordance with ASC 815-40 and are presented within warrant liabilities on our balance sheet. The warrant liabilities are measured at fair value at inception. ​ Initial Measurement ​ The Company established the initial fair value for the Warrants on March 2, 2021, the date of the Company’s Initial Public Offering, using a Monte Carlo simulation model. The Company allocated the proceeds received from (i) the sale of Units (which is inclusive of one share of common stock and one-third of one Public Warrant), (ii) the sale of Private Placement Warrants, and (iii) the issuance of common stock, first to the Warrants based on their fair values as determined at initial measurement, with the remaining proceeds allocated to common stock subject to possible redemption, and common stock based on their relative fair values at the initial measurement date. The Warrants were classified as Level 3 at the initial measurement date due to the use of unobservable inputs. ​ NOTE 9. FAIR VALUE MEASUREMENTS (cont.) ​ The key inputs into the Monte Carlo simulation model for the Private Placement Warrants and Public Warrants were as follows at initial measurement: ​ March 2, ​ 2021 ​ ​ ​ ​ Risk-free interest rate ​ ​ 0.071 % Expected term (years) ​ ​ 7 ​ Expected Volatility ​ ​ 13 % Exercise Price ​ $ 11.5 ​ Stock price ​ $ 9.55 ​ ​ On March 2, 2021, the Private Placement Warrants and Public Warrants were determined to be $1.40 and $1.37 per warrant for aggregate values of $8,376,666 and $14,442,083 , respectively. ​	Note 9 — Fair Value Measurements The Company follows the guidance in ASC 820 for its financial assets and liabilities that are re-measured and reported at fair value at each reporting period, and non-financial assets and liabilities that are re-measured and reported at fair value at least annually.

The warrant liabilities are measured at fair value at inception and on a recurring basis, with changes in fair value presented within change in fair value of warrant liabilities in the statement of operations. Initial Measurement The Company established the initial fair value for the Warrants on March 2, 2021, the date of the Company’s Initial Public Offering, using a Monte Carlo simulation model. The Company allocated the proceeds received from (i) the sale of Units (which is inclusive of one share of common stock and one-third of one Public Warrant), (ii) the sale of Private Placement Warrants, and (iii) the issuance of common stock, first to the Warrants based on their fair values as determined at initial measurement, with the remaining proceeds allocated to common stock subject to possible redemption, and common stock based on their relative fair values at the initial measurement date. The Warrants were classified as Level 3 at the initial measurement date due to the use of unobservable inputs. The key inputs into the Monte Carlo simulation model for the Private Placement Warrants and Public Warrants were as follows at initial measurement: ​ ​ ​ ​ ​ ​ ​ March 2, Input 2021 Risk-free interest rate ​ 0.71 % Expected term (years) ​ 7 ​ Expected Volatility ​ 13 % Exercise Price ​ $ 11.50 ​ Stock price ​ $ 9.55 ​ ​ On March 2, 2021, the Private Placement Warrants and Public Warrants were determined to be $1.40 and $1.37 per warrant for aggregate values of $8,376,666 and $14,442,083, respectively. Subsequent Measurement The Warrants are measured at fair value on a recurring basis. The subsequent measurement of the Public Warrants as of September 30, 2021 is classified as Level 1 due to the use of an observable market quote in an active market under the ticker MACQW. ​ Note 9 — Fair Value Measurements (continued) The key inputs into the Monte Carlo simulation model for the Private Placement Warrants were as follows at September 30, 2021: ​ ​ ​ ​ ​ ​ ​ ​ September 30, Input 2021 Risk-free interest rate ​ 0.98 % Expected term (years) ​ 5.1 ​ Expected Volatility ​ 12 % Exercise Price ​ $ 11.50 ​ Stock price ​ $ 9.87 ​ ​ On September 30, 2021, fair value of the Private Placement Warrants and Public Warrants were determined to be $2.04 and $1.08 per warrant for aggregate values of $12,206,000 and $11,385,000 respectively. The following table presents the changes in the fair value of warrant liabilities: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Private ​ ​ Warrant ​ Placement Public Liabilities ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Fair value ​ $ — ​ $ — ​ $ — Initial Measurement on March 2, 2021 ​ 8,376,666 ​ 14,442,083 ​ 22,818,749 Change in valuation inputs or other assumptions (1)(2) ​ 3,829,334 ​ (3,057,083) ​ 772,251 Fair value as of September 30, 2021 ​ $ 12,206,000 ​ $ 11,385,000 ​ $ 23,591,000 (1) Changes in valuation inputs or other assumptions are recognized in change in fair value of warrant liabilities in the Statement of Operations. (2) Due to the use of quoted prices in an active market (Level 1) and the use of observable inputs for similar assets or liabilities (Level 2) to measure the fair values of the Public Warrants and Private Placement Warrants, respectively, subsequent to initial measurement, the Company had transfers out of Level 3 totaling approximately $22,819,000 during the period from March 31, 2021 through September 30,2021. Because of the inherent uncertainty of valuation, estimated values using Level 3 inputs may be materially higher or lower than the values that would have been used had a ready market for investments existed. Accordingly, the degree of judgement exercised by the Company in determining fair value is greatest for investments categorized in Level 3. ​

Restatement of Previously Issue

Restatement of Previously Issued Financial Statements
Restatement of Previously Issued Financial Statements	NOTE 10. RESTATEMENT OF PREVIOUSLY ISSUED BALANCE SHEET ​ The Company previously accounted for its outstanding Public Warrants (as defined in Note 7) and Private Placement Warrants (collectively, with the Public Warrants, the “Warrants”) issued in connection with its Initial Public Offering as components of equity instead of as derivative liabilities. The Warrant Agreement governing the Warrants includes a provision that provides for potential changes to the settlement amounts dependent upon the characteristics of the holder of the warrant. In addition, the Warrant Agreement includes a provision that in the event of a tender offer or exchange offer made to and accepted by holders of more than 50% of the outstanding shares of a single class of stock, all holders of the Warrants would be entitled to receive cash for their Warrants (the “tender offer provision”). ​ On April 12, 2021, the Acting Director of the Division of Corporation Finance and Acting Chief Accountant of the Securities and Exchange Commission together issued a statement regarding the accounting and reporting considerations for warrants issued by special purpose acquisition companies entitled “Staff Statement on Accounting and Reporting Considerations for Warrants Issued by Special Purpose Acquisition Companies (“SPACs”)” (the “SEC Statement”). Specifically, the SEC Statement focused on certain settlement terms and provisions related to certain tender offers following a business combination, which terms are similar to those contained in the warrant agreement, dated as of February 25, 2021, between the Company and Continental Stock Transfer & Trust Company, a New York corporation, as warrant agent (the “Warrant Agreement”). ​ In further consideration of the SEC Statement, the Company’s management further evaluated the Warrants under Accounting Standards Codification (“ASC”) Subtopic 815-40, Contracts in Entity’s Own Equity. ASC Section 815-40-15 addresses equity versus liability treatment and classification of equity-linked financial instruments, including warrants, and states that a warrant may be classified as a component of equity only if, among other things, the warrant is indexed to the issuer’s common stock. Under ASC Section 815-40-15, a warrant is not indexed to the issuer’s common stock if the terms of the warrant require an adjustment to the exercise price upon a specified event and that event is not an input to the fair value of the warrant. Based on management’s evaluation, the Company’s audit committee, in consultation with management, concluded that the Company’s Private Placement Warrants are not indexed to the Company’s common stock in the manner contemplated by ASC Section 815-40-15 because the holder of the instrument is not an input into the pricing of a fixed-for-fixed option on equity shares. In addition, based on management’s evaluation, the Company’s audit committee, in consultation with management, concluded that the tender offer provision fails the “classified in stockholders’ equity” criteria as contemplated by ASC Section 815-40-25. ​ As a result of the above, the Company should have classified the Warrants as derivative liabilities in its previously issued balance sheet dated March 2, 2021, filed on Form 8-K/A on March 8, 2021. Under this accounting treatment, the Company is required to measure the fair value of the Warrants at the end of each reporting period as well as re-evaluate the treatment of the Warrants and recognize changes in the fair value from the prior period in the Company’s operating results for the current period. NOTE 10. RESTATEMENT OF PREVIOUSLY ISSUED BALANCE SHEET (cont.) ​ The Company’s accounting for the Warrants as components of equity instead of as derivative liabilities did not have any effect on the Company’s previously reported investments held in trust or cash as of March 2, 2021. ​ Additionally, the Company has concluded it will also restate its balance sheet dated March 2, 2021, filed on Form 8-K/A on March 8, 2021 to classify all Class A common stock subject to possible redemption in temporary equity. In accordance with the SEC and its staff’s guidance on redeemable equity instruments, ASC 480, paragraph 10-S99, redemption provisions not solely within the control of the Company require common stock subject to redemption to be classified outside of permanent equity. The Company had previously classified a portion of its Class A common stock in permanent equity, or total stockholders’ equity. Although the Company did not specify a maximum redemption threshold, its charter currently provides that, the Company will not redeem its public shares in an amount that would cause its net tangible assets to be less than $5,000,001 . The Company considered that the threshold would not change the nature of the underlying shares as redeemable and thus would be required to be disclosed outside equity. As a result of the above, the Company should have classified all of it Class A common stock as Class A common stock subject to possible redemption in temporary equity in its previously issued balance sheet dated March 2, 2021, filed on Form 8-K/A on March 8, 2021. The Company’s accounting for the Class A common stock as a component of equity instead of as Class A common stock subject to possible redemption in temporary equity did not have any effect on the Company’s previously reported investments held in trust or cash as of March 2, 2021. ​ Collectively the warrant liability and temporary equity restatements of the March 2, 2021 balance sheet resulted in a decrease of approximately $5.0 million in additional paid-in capital and a charge of approximately $31.7 million to accumulated deficit, as well as a reclassification of 1.387.316 shares of Class A common stock from permanent equity to temporary equity. The following table is a summary of the impact of the accounting for the warrant liability and temporary equity restatements on the balance sheet as of March 2, 2021. ​ ​ ​ ​ ​ ​ ​ ​ As Previously ​ Reported ​ Adjustment ​ As Restated ​ Balance sheet as of March 2, 2021 ​ ​ ​ ​ ​ ​ ​ Warrant liability ​ $ — ​ $ 22,818,749 ​ $ 22,818,749 ​ Total liabilities ​ ​ 12,185,686 ​ ​ 22,818,749 ​ ​ 35,004,435 ​ Class A common stock subject to possible redemption (1) ​ ​ 302,376,840 ​ ​ 13,873,160 ​ ​ 316,250,000 ​ Class A common stock ​ ​ 140 ​ ​ (140) ​ ​ — ​ Additional paid in capital ​ ​ 5,018,601 ​ ​ (5,018,601) ​ ​ — ​ Accumulated deficit ​ ​ (19,522) ​ ​ (31,673,168) ​ ​ (31,692,690) ​ (1) Shares of Class A common stock subject to possible redemption as Previously Reported as of March 2, 2021 were 30,237,684 , were Adjusted by 1,387,316 and are As Restated at 31,625,000 . ​	Note 11 — Restatement of Previously Issued Financial Statements The Company has concluded it will restate its financial statements to classify all Class A common stock subject to possible redemption in temporary equity as of September 30, 2021. In accordance with the SEC and its staff’s guidance on redeemable equity instruments, ASC 480, paragraph 10-S99, redemption provisions not solely within the control of the Company require common stock subject to redemption to be classified outside of permanent equity. The Company had previously classified a portion of its Class A common stock in permanent equity, or total stockholders’ equity. Although the Company did not specify a maximum redemption threshold, its charter currently provides that, the Company will not redeem its public shares in an amount that would cause its net tangible assets to be less than $5,000,001. The Company considered that the threshold would not change the nature of the underlying shares as redeemable and thus would be required to be disclosed outside equity. The change in the carrying value of the redeemable shares of Class A common stock at the Initial Public Offering resulted in a decrease of approximately $5.9 million in additional paid-in capital and a charge of approximately $30.8 million to accumulated deficit, as well as a reclassification of 3,669,191 shares of Class A common stock from permanent equity to temporary equity. As a result of the above, the Company should have classified all of it Class A common stock as Class A common stock subject to possible redemption in temporary equity in its previously issued financial statement. The Company’s accounting for the Class A common stock as a component of equity instead of as Class A common stock subject to possible redemption in temporary equity did not have any effect on the Company’s previously reported investments held in trust, operating expenses, cash flows or cash. ​ Note 11 — Restatement of Previously Issued Financial Statements (continued) The following tables are

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 independent registered public accounting firm attestation requirements of Section 404 of the Sarbanes-Oxley Act, 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. ​ NOTE 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (cont.) ​ 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 a company can elect to opt out of the extended transition period and comply with the requirements that apply to non-emerging growth companies but any such election to opt out is irrevocable. The Company has elected not to opt out of such 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 emerging growth company, can adopt the new or revised standard at the time private companies adopt the new or revised standard.

Use of Estimates	Use of Estimates ​ The preparation of the balance sheet 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 financial statements and the reported amounts of revenues and 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 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.

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 recognizes accrued interest and penalties related to unrecognized tax benefits, if any, as income tax expense. There were no unrecognized tax benefits and no amounts accrued for interest and penalties as of March 2, 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.

Class A Common Stock Subject to Possible Redemption	Class A Common Stock Subject to Possible Redemption ​ The Company accounts for its shares subject to possible redemption in accordance with the guidance in Accounting Standards Codification (“ASC”) Topic 480 “Distinguishing Liabilities from Equity.” Shares subject to mandatory redemption (if any) is classified as a liability instrument and is measured at fair value. Conditionally redeemable shares of common stock (including shares of common stock that feature redemption rights that are 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, shares are classified as stockholders’ equity. The Company’s shares feature certain redemption rights that are considered to be outside of the Company’s control and subject to occurrence of uncertain future events. Accordingly, at March 2, 2021, shares subject to possible redemption are presented as temporary equity, outside of the stockholders’ equity section of the Company’s balance sheet.

Accordingly, at September 30, 2021, 31,625,000 shares of Class A Common Stock subject to possible redemption are presented as temporary equity, outside of the stockholders’ equity section of the Company’s balance sheet.
Offering Costs	Offering Costs ​ Offering costs consist of legal, accounting, underwriting fees and other costs incurred through the balance sheet date that are directly related to the Initial Public Offering. Offering costs amounting to $17,853,629 were charged to stockholders’ equity upon the completion of the Initial Public Offering.
Cash Held in Trust Account	Cash Held in Trust Account ​ At March 2, 2021, the assets held in the Trust Account were held in cash.		Cash Held in Trust Account At September 30, 2021, the assets held in the Trust Account were invested in a money market fund.
Concentration of Credit Risk	Concentration 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 Depository Insurance Corporation coverage limit of $250,000 . The Company has not experienced losses on this account and management believes the Company is not exposed to significant risks on such account.

The Company has not experienced losses on this account and management believes the Company is not exposed to significant risks on such account.
Net Loss Per Share		Net Loss Per Common Share Net loss per share of common stock is computed by dividing net loss by the weighted average number of common shares outstanding during the period, excluding common shares subject to forfeiture. Weighted average shares were reduced for the effect of an aggregate of 1,031,250 shares of Class B common stock that are subject to forfeiture if the over-allotment option is not exercised by the underwriter (see Notes 7 and 8). At December 31, 2020, 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. As a result, diluted loss per share is the same as basic loss per share for the period presented.	Net Loss Per Share The Company complies with accounting and disclosure requirements of FASB ASC Topic 260, Earnings Per Share. Net loss per share is computed by dividing net income by the weighted average number of shares of common stock outstanding during the period. The Company has two classes of shares, Class A common stock and Class B common stock. Earnings and losses are shared pro rata between the two classes of common stock. The Company has not considered the effect of warrants sold in the Initial Public Offering and the private placement to purchase common stock in the calculation of diluted income per share, since the exercise of the warrants is contingent upon the occurrence of future events. As a result, diluted net loss per common share is the same as basic net loss per share for the period presented. The Company’s condensed statement of operations applies the two-class method in calculating net income per share. Basic and diluted net loss per share for Class A common stock and Class B common stock is calculated by dividing net loss attributable to the Company by the weighted average number of shares of Class A common stock and Class B common stock outstanding, allocated proportionally to each class of common stock. The following table reflects the calculation of basic and diluted net loss per ordinary share (in dollars, except per share amounts): ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ For the Three ​ For the ​ ​ Three Months Ended ​ Nine Months Ended ​ ​ September 30, ​ September 30, ​ 2021 2021 Class A common stock ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Net loss allocable to Class A common stock ​ $ (3,680,202) ​ $ (2,193,437) ​ ​ ​ ​ ​ ​ ​ Basic and diluted weighted ​ ​ 31,625,000 ​ ​ 24,674,451 Basic and diluted net ​ $ (0.12) ​ $ (0.09) Non-Redeemable Class B common stock ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Net loss allocable to Class B common stock ​ $ (920,051) ​ $ (702,826) ​ ​ ​ ​ ​ ​ ​ Basic and diluted weighted ​ ​ 7,906,250 ​ ​ 7,906,250 Basic and diluted net ​ $ (0.12) ​ $ (0.09)

Derivative Financial Instruments	Derivative Financial Instruments The Company evaluates its financial instruments to determine if such instruments are derivatives or contain features that qualify as embedded derivatives in accordance with ASC Topic 815, “Derivatives and Hedging”. For derivative financial instruments that are accounted for as liabilities, the derivative instrument is initially recorded at its fair value on the grant date and is then re-valued at each reporting date, with changes in the fair value reported in the statements of operations. The classification of derivative instruments, including whether such instruments should be recorded as liabilities or as equity, is evaluated at the end of each reporting period. Derivative liabilities are classified in the balance sheet as current or non-current based on whether or not net-cash settlement or conversion of the instrument could be required within 12 months of the balance sheet date.

(2) Due to the use of quoted prices in an active market (Level 1) and the use of observable inputs for similar assets or liabilities (Level 2) to measure the fair values of the Public Warrants and Private Placement Warrants, respectively, subsequent to initial measurement, the Company had transfers out of Level 3 totaling approximately $22,819,000 during the period from March 31, 2021 through September 30,2021. Because of the inherent uncertainty of valuation, estimated values using Level 3 inputs may be materially higher or lower than the values that would have been used had a ready market for investments existed. Accordingly, the degree of judgement exercised by the Company in determining fair value is greatest for investments categorized in Level 3.

[1]	Changes in valuation inputs or other assumptions are recognized in change in fair value of warrant liabilities in the Statement of Operations.
[2]	Due to the use of quoted prices in an active market (Level 1) and the use of observable inputs for similar assets or liabilities (Level 2) to measure the fair values of the Public Warrants and Private Placement Warrants, respectively, subsequent to initial measurement, the Company had transfers out of Level 3 totaling approximately $22,819,000 during the period from March 31, 2021 through September 30,2021. Because of the inherent uncertainty of valuation, estimated values using Level 3 inputs may be materially higher or lower than the values that would have been used had a ready market for investments existed. Accordingly, the degree of judgement exercised by the Company in determining fair value is greatest for investments categorized in Level 3.

On March 2, 2021, the Company consummated the Initial Public Offering of 31,625,000 units (“Units” and, with respect to the shares of Class A common stock included in the Units offered, the “Public Shares”), generating gross proceeds of $316,250,000 , which is described in Note 3. ​ Simultaneously with the closing of the Initial Public Offering, the Company consummated the sale of 5,983,333 private placement warrants (the “Private Placement Warrants”) at a price of $1.50 per warrant in a private placement to MCAP Acquisition, LLC (the “Sponsor”), generating gross proceeds of $8,975,000 , which is described in Note 4. ​ Following the closing of the Initial Public Offering on March 2, 2021, an amount of $316,250,000 ( $10.00 per Unit) from the net proceeds of the sale of the Units in the Initial Public Offering and the Private Placement Warrants was placed in a trust account (“Trust Account”) which may be invested in U.S. government securities, within the meaning set forth in Section 2(a)(16) of the Investment Company Act of 1940, as amended (the “Investment Company Act”), with a maturity of 185 days or less or in any open-ended investment company that holds itself out as a money market fund meeting the conditions of Rule 2a-7 of the Investment Company Act, as determined by the Company, until the earlier of: (i) the consummation of a Business Combination or (ii) the distribution of the Trust Account to the Company’s stockholders, as described below. ​ Transaction costs amounted to $17,853,629 consisting of $6,325,000 of underwriting fees, $11,068,750 of deferred underwriting fees (see Note 6) and $459,879 of other costs. In addition, $2,431,242 of cash was held outside of the Trust Account and is available for working capital purposes. ​ The Company’s management has broad discretion with respect to the specific application of the net proceeds of the Initial Public Offering and the sale of the Private Placement Warrants, although substantially all of the net proceeds are intended to be applied generally toward consummating a Business Combination. NASDAQ rules provide that the Business Combination must be with one or more target businesses that together have a fair market value equal to at least 80% of the balance in the Trust Account (as defined below) (less any deferred underwriting commissions and taxes payable on interest earned on the Trust Account) at the time of the signing of a definitive agreement to enter a Business Combination. The Company will only complete a Business Combination if the post-Business Combination company owns or acquires 50% or more of the outstanding voting securities of the target or otherwise acquires a controlling interest in the target sufficient for it not to be required to register as an investment company under the Investment Company Act. There is no assurance that the Company will be able to successfully effect a Business Combination. ​ The Company will provide its holders of the outstanding 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 either (i) in connection with a stockholder meeting called to approve the Business Combination or (ii) by means of a tender offer. In connection with a proposed Business Combination, the Company may seek stockholder approval of a Business Combination at a meeting called for such purpose at which stockholders may seek to redeem their shares, regardless of whether they vote for or against a Business Combination. The Company will proceed with a Business Combination only if the Company has net tangible assets of at least $5,000,001 either immediately prior to or upon such consummation of a Business Combination and, if the Company seeks stockholder approval, a majority of the outstanding shares voted are voted in favor of the Business Combination. ​ NOTE 1. DESCRIPTION OF ORGANIZATION AND BUSINESS OPERATIONS (cont.) ​ If the Company seeks stockholder approval of a Business Combination and it does not conduct redemptions pursuant to the tender offer rules, the Company’s Amended and Restated Certificate of Incorporation provides that a public stockholder, together with any affiliate of such stockholder or any other person with whom such stockholder is acting in concert or as a “group” (as defined under Section 13 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”)), will be restricted from seeking redemption rights with respect to 15% or more of the Public Shares without the Company’s prior written consent. ​ The public stockholders will be entitled to redeem their shares for a pro rata portion of the amount then in the Trust Account (initially $10.00 per 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 amount to be distributed to stockholders who redeem their shares will not be reduced by the deferred underwriting commissions the Company will pay to the underwriter (as discussed in Note 6). There will be no redemption rights upon the completion of a Business Combination with respect to the Company’s warrants. These shares of Class A common stock will be recorded at a redemption value and classified as temporary equity upon the completion of the Initial Public Offering, in accordance with Accounting Standards Codification (“ASC”) Topic 480 “Distinguishing Liabilities from Equity.” ​ If a stockholder vote is not required and the Company does not decide to hold a stockholder vote for business or other legal reasons, the Company will, pursuant to its Amended and Restated Certificate of Incorporation, offer such redemption pursuant to the tender offer rules of the Securities and Exchange Commission (the “SEC”), and file tender offer documents containing substantially the same information as would be included in a proxy statement with the SEC prior to completing a Business Combination. ​ The Company’s Sponsor has agreed (a) to vote its Founder Shares (as defined in Note 5) and any Public Shares purchased during or after the Initial Public Offering in favor of a Business Combination, (b) not to propose an amendment to the Company’s Amended and Restated Certificate of Incorporation with respect to the Company’s pre-Business Combination activities prior to the consummation of a Business Combination unless the Company provides dissenting public stockholders with the opportunity to redeem their Public Shares in conjunction with any such amendment; (c) not to redeem any shares (including the Founder Shares) and Private Placement Warrants into the right to receive cash from the Trust Account in connection with a stockholder vote to approve a Business Combination (or to sell any shares in a tender offer in connection with a Business Combination if the Company does not seek stockholder approval in connection therewith) or a vote to amend the provisions of the Amended and Restated Certificate of Incorporation relating to stockholders’ rights of pre-Business Combination activity and (d) that the Founder Shares and Private Placement Warrants shall not participate in any liquidating distributions upon winding up if a Business Combination is not consummated. However, the Sponsor will be entitled to liquidating distributions from the Trust Account with respect to any Public Shares purchased during or after the Initial Public Offering if the Company fails to complete its Business Combination. ​ The Company will have until March 2, 2023 to consummate a Business Combination. If the Company is unable to complete a Business Combination within 24 months from the closing of the Initial Public Offering (the “Combination Period”), the Company will (i) cease all operations except for the purpose of winding up, (ii) as promptly as reasonably possible but no more than ten business days thereafter, redeem the public shares, at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account, including interest earned on the funds held in the Trust Account and not previously released to the Company to pay taxes (less up to $100,000 of interest to pay dissolution expenses), divided by the number of then outstanding public shares, which redemption will completely extinguish public stockholders’ rights as stockholders (including the right to receive further liquidation distributions, if any), subject to applicable law, and (iii) as promptly as reasonably possible following such redemption, subject to the approval of the remaining stockholders and the Company’s board of directors, proceed to commence a voluntary liquidation and thereby a formal dissolution of the Company, subject in each case to its obligations under Delaware law to provide for claims of creditors and the requirements of applicable law. The underwriter has agreed to waive its rights to the deferred underwriting commission held in the Trust Account in the event the Company does not complete a Business Combination within the Combination Period and, in such event, such amounts will be included with the funds held in the Trust Account that will be available to fund the redemption of the Public Shares. In the event of such distribution, it is possible that the per share value of the assets remaining available for distribution will be less than the Initial Public Offering price per Unit ( $10.00 ). There will be no redemption rights or liquidating distributions with respect to the Founder Shares (as defined below) or the Private Placement Warrants, which will expire worthless if the Company fails to complete a Business Combination within the 24 -month time period. NOTE 1. DESCRIPTION OF ORGANIZATION AND BUSINESS OPERATIONS (cont.) ​ The Sponsor has agreed that it will be liable to the Company if and to the extent any claims by a third party for services rendered or products sold to the Company, or a prospective target business with which the Company has entered into a written letter of intent, confidentiality or similar agreement or Business Combination agreement, reduce the amount of funds in the Trust Account to below the lesser of (i) $10.00 per Public Share and (ii) the actual amount per Public Share held in the Trust Account as of the day of liquidation of the Trust Account, if less than $10.00 per share due to reductions in the value of the trust assets, less taxes payable, provided that such liability will not apply to any claims by a third party or prospective target business who executed a waiver of any and all rights to monies held in the Trust Account (whether or not such waiver is enforceable) nor will it apply to any claims under the Company’s indemnity of the underwriter of Initial Public Offering against certain liabilities, including liabilities under the Securities Act of 1933, as amended (the “Securities Act”). However, the Company has not asked the Sponsor to reserve for such indemnification obligations, nor has the Company independently verified whether the Sponsor has sufficient funds to satisfy its indemnity obligations and believe that the Sponsor’s only assets are securities of the Company. Therefore, the Company cannot assure its stockholders that the Sponsor would be able to satisfy those obligations. None of the Company’s officers or directors will indemnify the Company for claims by third parties including, without limitation, claims by vendors and prospective target businesses. The Company will seek to reduce the possibility that the Sponsor will have to indemnify the Trust Account due to claims of creditors by endeavoring to have all vendors, service providers, prospective target businesses or other entities with which the Company does business, execute agreements with the Company waiving any right, title, interest or claim of any kind in or to monies held in the Trust Account. ​ Management is currently evaluating the impact of the COVID-19 pandemic and has concluded that while it is reasonably possible that the virus could have a negative effect on the Company’s financial position, results of its operations and/or search for a target company, the specific impact is not readily determinable as of the date of the financial statement. The financial statement does not include any adjustments that might result from the outcome of this uncertainty. ​ Going Concern and Management’s Plans ​ The accompanying financial statement has been prepared on a going concern basis, which contemplates the realization of assets and the satisfaction of liabilities in the normal course of business. The Company’s management believes that its operations may not be sufficient to fund operating cash needs for at least 12 months from the issuance of this financial statement. The Company has no significant assets and has no revenue generating operations. There can be no assurance that the Company will be able to raise additional capital when needed, or at terms deemed acceptable, if at all. These factors raise substantial doubt about the Company’s ability to continue as a going concern for at least 12 months from the issuance of this financial statement. The accompanying financial statement does not include any adjustments relating to the recoverability and classification of asset carrying amounts or the amount and classification of liabilities that might result should the Company be unable to continue as a going concern. ​	MCAP ACQUISITION CORPORATION NOTES TO FINANCIAL STATEMENTS NOTE 1. DESCRIPTION OF ORGANIZATION AND BUSINESS OPERATIONS MCAP Acquisition Corporation (the “Company”) is a blank check company incorporated in Delaware on November 12, 2020. The Company was formed for the purpose of effectuating a merger, capital stock exchange, asset acquisition, stock purchase, reorganization or other similar business combination with one or more businesses (the “Business Combination”).The Company is an early stage and emerging growth company and, as such, the Company is subject to all of the risks associated with early stage and emerging growth companies. As of December 31, 2020, the Company had not yet commenced any operations. All activity for the period November 12, 2020 (inception) through December 31, 2020 relates to the Company’s formation and the proposed initial public offering (the “Proposed Offering”). The Company has selected December 31 as its fiscal year end. The Company’s ability to commence operations is contingent upon obtaining adequate financial resources through a proposed initial public offering of 27,500,000 units at $10.00 per unit (or 31,625,000 units if the underwriter’s over-allotment option is exercised in full) (the “Units” and, with respect to the shares of Class A common stock included in the Units being offered, the “Public Shares”) which is discussed in Note 3 and the sale of 5,433,333 warrants (or 5,983,333 warrants if the underwriter’s over-allotment option is exercised in full) (the “Private Placement Warrants”) at a price of $1.50 per Private Placement Warrant that will close in a private placement to MCAP Acquisition, LLC (the “Sponsor”) simultaneously with the closing of the Proposed Offering (see Note 4). The Company’s management has broad discretion with respect to the specific application of the net proceeds of the Proposed Offering and the sale of the Private Placement Warrants, although substantially all of the net proceeds are intended to be applied generally toward consummating a Business Combination. NASDAQ rules provide that the Business Combination must be with one or more target businesses that together have a fair market value equal to at least 80% of the balance in the Trust Account (as defined below) (less any deferred underwriting commissions and taxes payable on interest earned on the Trust Account) at the time of the signing a definitive agreement to enter a Business Combination.

There is no assurance that the Company will be able to successfully effect a Business Combination. Upon the closing of the Proposed Offering, management has agreed that $10.00 per Unit sold in the Proposed Offering, including the proceeds from the sale of the Private Placement Warrants, will be held in a trust account (the “Trust Account”) and invested in U.S. government securities, within the meaning set forth in Section 2(a)(16) of the Investment Company Act, with a maturity of 185 days or less, or in any open-ended investment company that holds itself out as a money market fund meeting the conditions of Rule 2a-7 of the Investment Company Act, as determined by the Company, until the earlier of: (i) the consummation of a Business Combination or (ii) the distribution of the funds in the Trust Account to the Company’s stockholders, as described below.

Going Concern Consideration At December 31, 2020, the Company had $25,000 in cash and working capital deficit of $140,584. The Company has incurred and expects to continue to incur significant costs in pursuit of its financing and acquisition plans. These conditions raise substantial doubt about the Company’s ability to continue as a going concern for a period of time within one year after the date that the financial statements are issued. Management plans to address this uncertainty through the Proposed Offering as discussed in Note 3. There is no assurance that the Company’s plans to raise capital or to consummate a Business Combination will be successful or successful within the Combination Period. The financial statements do not include any adjustments that might result from the outcome of this uncertainty.	Note 1 — Description of Organization and Business Operations MCAP Acquisition Corporation (the “Company”) is a blank check company incorporated in Delaware on November 12, 2020. The Company was formed for the purpose of effectuating a merger, capital stock exchange, asset acquisition, stock purchase, reorganization or other similar business combination with one or more businesses (the “Business Combination”). The Company is an early stage and emerging growth company and, as such, the Company is subject to all of the risks associated with early stage and emerging growth companies. The accompanying condensed consolidated financial statements includes the Company and its wholly owned subsidiaries GRNT Merger Sub 1 LLC, GRNT Merger Sub 2 LLC, GRNT Merger Sub 3 LLC, and GRNT Merger Sub 4 LLC. As of September 30, 2021, the Company had not yet commenced any operations. All activity for the period November 12, 2020 (inception) through September 30, 2021 relates to the Company’s formation, initial public offering (the “Initial Public Offering”) and search to effectuate a Business Combination. The Company has selected December 31 as its fiscal year end. The registration statement for the Company’s Initial Public Offering was declared effective on February 25, 2021. On March 2, 2021, the Company consummated the Initial Public Offering of 31,625,000 units (“Units” and, with respect to the shares of Class A common stock included in the Units offered, the “Public Shares”), generating gross proceeds of $316,250,000, which is described in Note 3.

Following the closing of the Initial Public Offering $2,431,242 of cash was held outside of the Trust Account available for working capital purposes. As of September 30, 2021, we have available to us $797,602 of cash on our balance sheet and a working capital surplus of $706,131. The Company’s management has broad discretion with respect to the specific application of the net proceeds of the Initial Public Offering and the sale of the Private Placement Warrants, although substantially all of the net proceeds are intended to be applied generally toward consummating a Business Combination.

SUMMARY OF SIGNIFICANT ACCOUN_6

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	Mar. 02, 2021	Dec. 31, 2020	Sep. 30, 2021
Summary of Significant Accounting Policies
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	NOTE 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES ​ Basis of Presentation ​ The accompanying balance sheet has been prepared in conformity with accounting principles generally accepted in the United States of America (“GAAP”) and pursuant to the rules and regulations of the SEC. ​ 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 independent registered public accounting firm attestation requirements of Section 404 of the Sarbanes-Oxley Act, 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. ​ NOTE 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (cont.) ​ 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 a company can elect to opt out of the extended transition period and comply with the requirements that apply to non-emerging growth companies but any such election to opt out is irrevocable. The Company has elected not to opt out of such 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 emerging growth company, can adopt the new or revised standard at the time private companies adopt the new or revised standard. This may make comparison of the Company’s financial statements with another public company, which is neither an emerging growth company nor an emerging growth company which has opted out of using the extended transition period difficult or impossible because of the potential differences in accounting standards used. ​ Use of Estimates ​ The preparation of the balance sheet 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 financial statements and the reported amounts of revenues and 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 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 highly liquid investments purchased with an original maturity of three months or less to be cash equivalents. Cash equivalents are carried at cost, which approximates fair value. The Company had $2,431,242 in cash and no cash equivalents as of March 2, 2021. ​ 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 recognizes accrued interest and penalties related to unrecognized tax benefits, if any, as income tax expense. There were no unrecognized tax benefits and no amounts accrued for interest and penalties as of March 2, 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. ​ NOTE 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (cont.) ​ Class A Common Stock Subject to Possible Redemption ​ The Company accounts for its shares subject to possible redemption in accordance with the guidance in Accounting Standards Codification (“ASC”) Topic 480 “Distinguishing Liabilities from Equity.” Shares subject to mandatory redemption (if any) is classified as a liability instrument and is measured at fair value. Conditionally redeemable shares of common stock (including shares of common stock that feature redemption rights that are 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, shares are classified as stockholders’ equity. The Company’s shares feature certain redemption rights that are considered to be outside of the Company’s control and subject to occurrence of uncertain future events. Accordingly, at March 2, 2021, shares subject to possible redemption are presented as temporary equity, outside of the stockholders’ equity section of the Company’s balance sheet. ​ Offering Costs ​ Offering costs consist of legal, accounting, underwriting fees and other costs incurred through the balance sheet date that are directly related to the Initial Public Offering. Offering costs amounting to $17,853,629 were charged to stockholders’ equity upon the completion of the Initial Public Offering. ​ Cash Held in Trust Account ​ At March 2, 2021, the assets held in the Trust Account were held in cash. ​ Concentration 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 Depository Insurance Corporation coverage limit of $250,000 . The Company has not experienced losses on this account and management believes the Company is not exposed to significant risks on such account. ​ Fair Value of Financial Instruments ​ The fair value of the Company’s assets and liabilities, which qualify as financial instruments under ASC Topic 820, “Fair Value Measurement,” approximates the carrying amounts represented in the accompanying balance sheet, primarily due to their short-term nature. ​ Derivative Financial Instruments The Company evaluates its financial instruments to determine if such instruments are derivatives or contain features that qualify as embedded derivatives in accordance with ASC Topic 815, “Derivatives and Hedging”. For derivative financial instruments that are accounted for as liabilities, the derivative instrument is initially recorded at its fair value on the grant date and is then re-valued at each reporting date, with changes in the fair value reported in the statements of operations. The classification of derivative instruments, including whether such instruments should be recorded as liabilities or as equity, is evaluated at the end of each reporting period. Derivative liabilities are classified in the balance sheet as current or non-current based on whether or not net-cash settlement or conversion of the instrument could be required within 12 months of the balance sheet date. ​ Recently Issued Accounting Standards ​ 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 financial statements. ​	NOTE 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Basis of Presentation The accompanying 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. 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 independent registered public accounting firm attestation requirements of Section 404 of the Sarbanes-Oxley Act, 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 a company can elect to opt out of the extended transition period and comply with the requirements that apply to non-emerging growth companies but any such election to opt out is irrevocable. The Company has elected not to opt out of such 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 emerging growth company, can adopt the new or revised standard at the time private companies adopt the new or revised standard. This may make comparison of the Company’s financial statements with another public company, which is neither an emerging growth company nor an emerging growth company which has opted out of using the extended transition period difficult or impossible because of the potential differences in accounting standards used. Use of Estimates The preparation of 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 financial statements and the reported amounts of revenue and 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 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 did not have any cash equivalents as of December 31, 2020. 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 recognizes accrued interest and penalties related to unrecognized tax benefits, if any, as income tax expense. There were no unrecognized tax benefits and no amounts accrued for interest and penalties as of December 31, 2020. 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 provision for income taxes was deemed to be immaterial for the period from November 12, 2020 (inception) through December 31, 2020. Net Loss Per Common Share Net loss per share of common stock is computed by dividing net loss by the weighted average number of common shares outstanding during the period, excluding common shares subject to forfeiture. Weighted average shares were reduced for the effect of an aggregate of 1,031,250 shares of Class B common stock that are subject to forfeiture if the over-allotment option is not exercised by the underwriter (see Notes 7 and 8). At December 31, 2020, 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. As a result, diluted loss per share is the same as basic loss per share for the period presented. Concentration 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 Depository Insurance Corporation coverage limit of $250,000. The Company has not experienced losses on this account and management believes the Company is not exposed to significant risks on such account. Fair Value of Financial Instruments The fair value of the Company’s assets and liabilities, which qualify as financial instruments under ASC Topic 820, “Fair Value Measurement,” approximates the carrying amounts represented in the accompanying balance sheet, primarily due to their short-term nature. Recently Issued Accounting Standards 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 financial statements. Subsequent Events Management of the Company evaluates events that have occurred after the balance sheet date of December 31, 2020 through the date these financial statements were issued. Based upon the review, management did not identify any recognized or non-recognized subsequent events that would have required adjustment or disclosure in the financial statements, except as follows. On February 25, 2021, the Company’s Board of Directors approved a stock dividend of 718,750 shares of Class B common stock (the “Stock Dividend”). The par values of the common and preferred stock were not adjusted as a result of the Stock Dividend. All references to common stock, warrants to purchase common stock, share data, per share data, and related information contained in the financial statements have been retroactively adjusted to reflect this Stock Dividend for all periods presented.	Note 2 — Summary of Significant Accounting Policies Basis of Presentation The accompanying financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“US GAAP”) and pursuant to the accounting and disclosure rules and regulations of the U.S. Securities and Exchange Commission. In preparation of the Company’s unaudited condensed consolidated financial statements as of and for quarterly period ended September 30, 2021, the Company concluded it will restate its financial statements to classify all Class A common shares as Class A common stock subject to possible redemption in temporary equity as of September 30, 2021 (see Note 11). 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 independent registered public accounting firm attestation requirements of Section 404 of the Sarbanes-Oxley Act, 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. ​ Note 2 — Summary of Significant Accounting Policies (continued) 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.

Accordingly, the actual results could differ significantly from those estimates. Cash and Cash Equivalents The Company considers all highly liquid investments purchased with an original maturity of three months or less to be cash equivalents. Cash equivalents are carried at cost, which approximates fair value. The Company had $797,602 in cash and no cash equivalents as of September 30, 2021. 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.

The Company recognizes accrued interest and penalties related to unrecognized tax benefits, if any, as income tax expense. There were no unrecognized tax benefits and no amounts accrued for interest and penalties as of September 30, 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 provision for income taxes was deemed to be immaterial for the three and nine months ended September 30, 2021. ​ Note 2 — Summary of Significant Accounting Policies (continued) Class A Common Stock Subject to Possible Redemption The Company accounts for its shares subject to possible redemption in accordance with the guidance in Accounting Standards Codification (“ASC”) Topic 480 “Distinguishing Liabilities from Equity.” Shares subject to mandatory redemption (if any) is classified as a liability instrument and is measured at fair value. Conditionally redeemable shares of common stock (including shares of common stock that feature redemption rights that are 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, shares are classified as stockholders’ equity. The Company’s shares feature certain redemption rights that are considered to be outside of the Company’s control and subject to occurrence of uncertain future events. Accordingly, at September 30, 2021, 31,625,000 shares of Class A Common Stock subject to possible redemption are presented as temporary equity, outside of the stockholders’ equity section of the Company’s balance sheet. Cash Held in Trust Account At September 30, 2021, the assets held in the Trust Account were invested in a money market fund. Concentration 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 Depository Insurance Corporation coverage limit of $250,000. The Company has not experienced losses on this account and management believes the Company is not exposed to significant risks on such account. Net Loss Per Share The Company complies with accounting and disclosure requirements of FASB ASC Topic 260, Earnings Per Share. Net loss per share is computed by dividing net income by the weighted average number of shares of common stock outstanding during the period. The Company has two classes of shares, Class A common stock and Class B common stock. Earnings and losses are shared pro rata between the two classes of common stock. The Company has not considered the effect of warrants sold in the Initial Public Offering and the private placement to purchase common stock in the calculation of diluted income per share, since the exercise of the warrants is contingent upon the occurrence of future events. As a result, diluted net loss per common share is the same as basic net loss per share for the period presented. The Company’s condensed statement of operations applies the two-class method in calculating net income per share. Basic and diluted net loss per share for Class A common stock and Class B common stock is calculated by dividing net loss attributable to the Company by the weighted average number of shares of Class A common stock and Class B common stock outstanding, allocated proportionally to each class of common stock. ​ Note 2 — Summary of Significant Accounting Policies (continued) The following table reflects the calculation of basic and diluted net loss per ordinary share (in dollars, except per share amounts): ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ For the Three ​ For the ​ ​ Three Months Ended ​ Nine Months Ended ​ ​ September 30, ​ September 30, ​ 2021 2021 Class A common stock ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Net loss allocable to Class A common stock ​ $ (3,680,202) ​ $ (2,193,437) ​ ​ ​ ​ ​ ​ ​ Basic and diluted weighted ​ ​ 31,625,000 ​ ​ 24,674,451 Basic and diluted net ​ $ (0.12) ​ $ (0.09) Non-Redeemable Class B common stock ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Net loss allocable to Class B common stock ​ $ (920,051) ​ $ (702,826) ​ ​ ​ ​ ​ ​ ​ Basic and diluted weighted ​ ​ 7,906,250 ​ ​ 7,906,250 Basic and diluted net ​ $ (0.12) ​ $ (0.09) ​ Fair Value of Financial Instruments The fair value of the Company’s assets and liabilities, which qualify as financial instruments under ASC Topic 820, “Fair Value Measurement,” approximates the carrying amounts represented in the accompanying balance sheet, primarily due to their short-term nature.

Warrant Liability
WARRANT LIABILITY	NOTE 7. WARRANT LIABILITY ​ Public Warrants may only be exercised for a whole number of shares. No fractional shares will be issued upon exercise of the Public Warrants. The Public Warrants will become exercisable on the later of (a) 30 days after the consummation of a Business Combination or (b) 12 months from the closing of the Initial Public Offering. The Public Warrants will expire five years from the consummation of a Business Combination or earlier upon redemption or liquidation. ​ The Company will not be obligated to deliver any Class A common stock pursuant to the exercise of a Public Warrant and will have no obligation to settle such Public Warrant exercise unless a registration statement under the Securities Act covering the issuance of the Class A common stock issuable upon exercise of the Public Warrants is then effective and a prospectus relating thereto is current, subject to the Company satisfying its obligations with respect to registration. No Public Warrant will be exercisable for cash or on a cashless basis, and the Company will not be obligated to issue any shares to holders seeking to exercise their Public Warrants, unless the issuance of the shares upon such exercise is registered or qualified under the securities laws of the state of the exercising holder, or an exemption from registration is available. ​ NOTE 7. WARRANT LIABILITY (cont.) ​ The Company has agreed that as soon as practicable, but in no event later than 15 business days after the closing of its initial Business Combination, it will use its best efforts to file with the SEC, and within 60 business days following its initial Business Combination to have declared effective, a registration statement covering the issuance of 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. If a registration statement covering the shares of Class A common stock issuable upon exercise of the warrants is not effective by the 60 th business day after the closing of a 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. ​ Once the Public Warrants become exercisable, the Company may redeem the Public Warrants for redemption: ​ ● in whole and not in part; ● at a price of $0.01 per Public Warrant; ● upon not less than 30 days’ prior written notice of redemption to each warrant holder; and ● if, and only if, the reported last sale price of the Class A common stock equals or exceeds $18.00 per share (as adjusted for stock splits, stock dividends, reorganizations, recapitalizations and the like and certain issuances of Class A common stock and equity-linked securities) for any 20 trading days within a 30 -trading day period commencing no earlier than the date the warrants become exercisable and ending on the third business day before the date on which the Company sends the notice of redemption to the warrant holders. ​ If and when the Public Warrants become redeemable by the Company, the Company may not exercise its redemption right if the issuance of shares of common stock upon exercise of the warrants is not exempt from registration or qualification under applicable state blue sky laws or the Company is unable to effect such registration or qualification. ​ The Company accounts for the 10,541,667 Public Warrants issued in connection with the Initial Public Offering and the 5,983,333 Private Placement Warrants in accordance with the guidance contained in ASC 815-40. Such guidance provides that because the warrants do not meet the criteria for equity treatment thereunder, each warrant must be recorded as a liability. The warrant agreement contains an Alternative Issuance provision that if less than 70% of the consideration receivable by the holders of the Class A common stock in the Business Combination is payable in the form of common equity in the successor entity, and if the holders of the warrants properly exercises the warrants within thirty days following the public disclosure of the consummation of Business Combination by the Company, the warrant price shall be reduced by an amount equal to the difference (but in no event less than zero) of (i) the warrant price in effect prior to such reduction minus (ii) (A) the Per Share Consideration (as defined below) minus (B) the Black-Scholes Warrant Value (as defined below). The “Black-Scholes Warrant Value” means the value of a Warrant immediately prior to the consummation of the Business Combination based on the Black-Scholes Warrant Model for a Capped American Call on Bloomberg Financial Markets. “Per Share Consideration” means (i) if the consideration paid to holders of the common stock consists exclusively of cash, the amount of such cash per common stock, and (ii) in all other cases, the volume weighted average price of the common stock as reported during the ten-trading day period ending on the trading day prior to the effective date of the Business Combination. ​ NOTE 7. WARRANT LIABILITY (cont.) ​ The Company believes that the adjustments to the exercise price of the warrants is based on a variable that is not an input to the fair value of a “fixed-for-fixed” option as defined under FASB ASC Topic No. 815 – 40, and thus the warrants are not eligible for an exception from derivative accounting. The accounting treatment of derivative financial instruments requires that the Company record a derivative liability upon the closing of the Initial Public Offering. Accordingly, the Company will classify each warrant as a liability at its fair value and the warrants will be allocated a portion of the proceeds from the issuance of the Units equal to its fair value determined by the Monte Carlo simulation. This liability is subject to re-measurement at each balance sheet date. With each such remeasurement, the warrant liability will be adjusted to fair value, with the change in fair value recognized in the Company’s statement of operations. The Company will reassess the classification at each balance sheet date. If the classification changes as a result of events during the period, the warrants will be reclassified as of the date of the event that causes the reclassification. ​ The Private Placement Warrants will be identical to the Public Warrants underlying the Units being sold in the Initial Public Offering, except that the Private Placement Warrants and the shares of common stock issuable upon the exercise of the Private Placement Warrants will not be transferable, assignable or salable until 30 days after the completion of a Business Combination, subject to certain limited exceptions. Additionally, the Private Placement Warrants will be exercisable on a cashless basis and will be non-redeemable so long as they are held by the initial purchasers or their permitted transferees (other than in the case the Public Warrants are redeemed for $0.10 as described above). If the Private Placement Warrants are held by someone other than the initial purchasers or their permitted transferees, the Private Placement Warrants will be redeemable by the Company and exercisable by such holders on the same basis as the Public Warrants. ​	Note 7 — Warrant Liability Public Warrants may only be exercised for a whole number of shares.

Fair Value Measurements
FAIR VALUE MEASUREMENTS	NOTE 9. FAIR VALUE MEASUREMENTS ​ The Company follows the guidance in ASC 820 for its financial assets and liabilities that are re-measured and reported at fair value at each reporting period, and non-financial assets and liabilities that are re-measured and reported at fair value at least annually. 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 (unadjusted) 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. ​ ​ ​ ​ ​ Level March 2, 2021 Assets: ​ ​ ​ ​ Cash and marketable securities held in Trust Account ​ 1 ​ $ 316,250,000 ​ ​ ​ ​ ​ Liabilities: ​ ​ ​ ​ Public Warrants ​ 3 ​ $ 14,442,083 ​ Private Placement Warrants ​ 3 ​ $ 8,376,666 ​ ​ The Warrants were accounted for as liabilities in accordance with ASC 815-40 and are presented within warrant liabilities on our balance sheet.

The key inputs into the Monte Carlo simulation model for the Private Placement Warrants and Public Warrants were as follows at initial measurement: ​ ​ ​ ​ ​ ​ ​ March 2, Input 2021 Risk-free interest rate ​ 0.71 % Expected term (years) ​ 7 ​ Expected Volatility ​ 13 % Exercise Price ​ $ 11.50 ​ Stock price ​ $ 9.55 ​ ​ On March 2, 2021, the Private Placement Warrants and Public Warrants were determined to be $1.40 and $1.37 per warrant for aggregate values of $8,376,666 and $14,442,083, respectively. Subsequent Measurement The Warrants are measured at fair value on a recurring basis. The subsequent measurement of the Public Warrants as of September 30, 2021 is classified as Level 1 due to the use of an observable market quote in an active market under the ticker MACQW. ​ Note 9 — Fair Value Measurements (continued) The key inputs into the Monte Carlo simulation model for the Private Placement Warrants were as follows at September 30, 2021: ​ ​ ​ ​ ​ ​ ​ ​ September 30, Input 2021 Risk-free interest rate ​ 0.98 % Expected term (years) ​ 5.1 ​ Expected Volatility ​ 12 % Exercise Price ​ $ 11.50 ​ Stock price ​ $ 9.87 ​ ​ On September 30, 2021, fair value of the Private Placement Warrants and Public Warrants were determined to be $2.04 and $1.08 per warrant for aggregate values of $12,206,000 and $11,385,000 respectively. The following table presents the changes in the fair value of warrant liabilities: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Private ​ ​ Warrant ​ Placement Public Liabilities ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Fair value ​ $ — ​ $ — ​ $ — Initial Measurement on March 2, 2021 ​ 8,376,666 ​ 14,442,083 ​ 22,818,749 Change in valuation inputs or other assumptions (1)(2) ​ 3,829,334 ​ (3,057,083) ​ 772,251 Fair value as of September 30, 2021 ​ $ 12,206,000 ​ $ 11,385,000 ​ $ 23,591,000 (1) Changes in valuation inputs or other assumptions are recognized in change in fair value of warrant liabilities in the Statement of Operations. (2) Due to the use of quoted prices in an active market (Level 1) and the use of observable inputs for similar assets or liabilities (Level 2) to measure the fair values of the Public Warrants and Private Placement Warrants, respectively, subsequent to initial measurement, the Company had transfers out of Level 3 totaling approximately $22,819,000 during the period from March 31, 2021 through September 30,2021. Because of the inherent uncertainty of valuation, estimated values using Level 3 inputs may be materially higher or lower than the values that would have been used had a ready market for investments existed. Accordingly, the degree of judgement exercised by the Company in determining fair value is greatest for investments categorized in Level 3. ​

RESTATEMENT OF PREVIOUSLY ISS_4

RESTATEMENT OF PREVIOUSLY ISSUED BALANCE SHEET	Mar. 02, 2021	Sep. 30, 2021
Restatement of Previously Issued Financial Statements
RESTATEMENT OF PREVIOUSLY ISSUED BALANCE SHEET	NOTE 10. RESTATEMENT OF PREVIOUSLY ISSUED BALANCE SHEET ​ The Company previously accounted for its outstanding Public Warrants (as defined in Note 7) and Private Placement Warrants (collectively, with the Public Warrants, the “Warrants”) issued in connection with its Initial Public Offering as components of equity instead of as derivative liabilities. The Warrant Agreement governing the Warrants includes a provision that provides for potential changes to the settlement amounts dependent upon the characteristics of the holder of the warrant. In addition, the Warrant Agreement includes a provision that in the event of a tender offer or exchange offer made to and accepted by holders of more than 50% of the outstanding shares of a single class of stock, all holders of the Warrants would be entitled to receive cash for their Warrants (the “tender offer provision”). ​ On April 12, 2021, the Acting Director of the Division of Corporation Finance and Acting Chief Accountant of the Securities and Exchange Commission together issued a statement regarding the accounting and reporting considerations for warrants issued by special purpose acquisition companies entitled “Staff Statement on Accounting and Reporting Considerations for Warrants Issued by Special Purpose Acquisition Companies (“SPACs”)” (the “SEC Statement”). Specifically, the SEC Statement focused on certain settlement terms and provisions related to certain tender offers following a business combination, which terms are similar to those contained in the warrant agreement, dated as of February 25, 2021, between the Company and Continental Stock Transfer & Trust Company, a New York corporation, as warrant agent (the “Warrant Agreement”). ​ In further consideration of the SEC Statement, the Company’s management further evaluated the Warrants under Accounting Standards Codification (“ASC”) Subtopic 815-40, Contracts in Entity’s Own Equity. ASC Section 815-40-15 addresses equity versus liability treatment and classification of equity-linked financial instruments, including warrants, and states that a warrant may be classified as a component of equity only if, among other things, the warrant is indexed to the issuer’s common stock. Under ASC Section 815-40-15, a warrant is not indexed to the issuer’s common stock if the terms of the warrant require an adjustment to the exercise price upon a specified event and that event is not an input to the fair value of the warrant. Based on management’s evaluation, the Company’s audit committee, in consultation with management, concluded that the Company’s Private Placement Warrants are not indexed to the Company’s common stock in the manner contemplated by ASC Section 815-40-15 because the holder of the instrument is not an input into the pricing of a fixed-for-fixed option on equity shares. In addition, based on management’s evaluation, the Company’s audit committee, in consultation with management, concluded that the tender offer provision fails the “classified in stockholders’ equity” criteria as contemplated by ASC Section 815-40-25. ​ As a result of the above, the Company should have classified the Warrants as derivative liabilities in its previously issued balance sheet dated March 2, 2021, filed on Form 8-K/A on March 8, 2021. Under this accounting treatment, the Company is required to measure the fair value of the Warrants at the end of each reporting period as well as re-evaluate the treatment of the Warrants and recognize changes in the fair value from the prior period in the Company’s operating results for the current period. NOTE 10. RESTATEMENT OF PREVIOUSLY ISSUED BALANCE SHEET (cont.) ​ The Company’s accounting for the Warrants as components of equity instead of as derivative liabilities did not have any effect on the Company’s previously reported investments held in trust or cash as of March 2, 2021. ​ Additionally, the Company has concluded it will also restate its balance sheet dated March 2, 2021, filed on Form 8-K/A on March 8, 2021 to classify all Class A common stock subject to possible redemption in temporary equity. In accordance with the SEC and its staff’s guidance on redeemable equity instruments, ASC 480, paragraph 10-S99, redemption provisions not solely within the control of the Company require common stock subject to redemption to be classified outside of permanent equity. The Company had previously classified a portion of its Class A common stock in permanent equity, or total stockholders’ equity. Although the Company did not specify a maximum redemption threshold, its charter currently provides that, the Company will not redeem its public shares in an amount that would cause its net tangible assets to be less than $5,000,001 . The Company considered that the threshold would not change the nature of the underlying shares as redeemable and thus would be required to be disclosed outside equity. As a result of the above, the Company should have classified all of it Class A common stock as Class A common stock subject to possible redemption in temporary equity in its previously issued balance sheet dated March 2, 2021, filed on Form 8-K/A on March 8, 2021. The Company’s accounting for the Class A common stock as a component of equity instead of as Class A common stock subject to possible redemption in temporary equity did not have any effect on the Company’s previously reported investments held in trust or cash as of March 2, 2021. ​ Collectively the warrant liability and temporary equity restatements of the March 2, 2021 balance sheet resulted in a decrease of approximately $5.0 million in additional paid-in capital and a charge of approximately $31.7 million to accumulated deficit, as well as a reclassification of 1.387.316 shares of Class A common stock from permanent equity to temporary equity. The following table is a summary of the impact of the accounting for the warrant liability and temporary equity restatements on the balance sheet as of March 2, 2021. ​ ​ ​ ​ ​ ​ ​ ​ As Previously ​ Reported ​ Adjustment ​ As Restated ​ Balance sheet as of March 2, 2021 ​ ​ ​ ​ ​ ​ ​ Warrant liability ​ $ — ​ $ 22,818,749 ​ $ 22,818,749 ​ Total liabilities ​ ​ 12,185,686 ​ ​ 22,818,749 ​ ​ 35,004,435 ​ Class A common stock subject to possible redemption (1) ​ ​ 302,376,840 ​ ​ 13,873,160 ​ ​ 316,250,000 ​ Class A common stock ​ ​ 140 ​ ​ (140) ​ ​ — ​ Additional paid in capital ​ ​ 5,018,601 ​ ​ (5,018,601) ​ ​ — ​ Accumulated deficit ​ ​ (19,522) ​ ​ (31,673,168) ​ ​ (31,692,690) ​ (1) Shares of Class A common stock subject to possible redemption as Previously Reported as of March 2, 2021 were 30,237,684 , were Adjusted by 1,387,316 and are As Restated at 31,625,000 . ​	Note 11 — Restatement of Previously Issued Financial Statements The Company has concluded it will restate its financial statements to classify all Class A common stock subject to possible redemption in temporary equity as of September 30, 2021. In accordance with the SEC and its staff’s guidance on redeemable equity instruments, ASC 480, paragraph 10-S99, redemption provisions not solely within the control of the Company require common stock subject to redemption to be classified outside of permanent equity.

The Company considered that the threshold would not change the nature of the underlying shares as redeemable and thus would be required to be disclosed outside equity. The change in the carrying value of the redeemable shares of Class A common stock at the Initial Public Offering resulted in a decrease of approximately $5.9 million in additional paid-in capital and a charge of approximately $30.8 million to accumulated deficit, as well as a reclassification of 3,669,191 shares of Class A common stock from permanent equity to temporary equity. As a result of the above, the Company should have classified all of it Class A common stock as Class A common stock subject to possible redemption in temporary equity in its previously issued financial statement. The Company’s accounting for the Class A common stock as a component of equity instead of as Class A common stock subject to possible redemption in temporary equity did not have any effect on the Company’s previously reported investments held in trust, operating expenses, cash flows or cash. ​ Note 11 — Restatement of Previously Issued Financial Statements (continued) The following tables are

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 independent registered public accounting firm attestation requirements of Section 404 of the Sarbanes-Oxley Act, 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. ​ NOTE 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (cont.) ​ 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 a company can elect to opt out of the extended transition period and comply with the requirements that apply to non-emerging growth companies but any such election to opt out is irrevocable. The Company has elected not to opt out of such 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 emerging growth company, can adopt the new or revised standard at the time private companies adopt the new or revised standard.

Use of Estimates	Use of Estimates ​ The preparation of the balance sheet 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 financial statements and the reported amounts of revenues and 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 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.

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 recognizes accrued interest and penalties related to unrecognized tax benefits, if any, as income tax expense. There were no unrecognized tax benefits and no amounts accrued for interest and penalties as of March 2, 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.

(2) Due to the use of quoted prices in an active market (Level 1) and the use of observable inputs for similar assets or liabilities (Level 2) to measure the fair values of the Public Warrants and Private Placement Warrants, respectively, subsequent to initial measurement, the Company had transfers out of Level 3 totaling approximately $22,819,000 during the period from March 31, 2021 through September 30,2021. Because of the inherent uncertainty of valuation, estimated values using Level 3 inputs may be materially higher or lower than the values that would have been used had a ready market for investments existed. Accordingly, the degree of judgement exercised by the Company in determining fair value is greatest for investments categorized in Level 3.

[1]	Changes in valuation inputs or other assumptions are recognized in change in fair value of warrant liabilities in the Statement of Operations.
[2]	Due to the use of quoted prices in an active market (Level 1) and the use of observable inputs for similar assets or liabilities (Level 2) to measure the fair values of the Public Warrants and Private Placement Warrants, respectively, subsequent to initial measurement, the Company had transfers out of Level 3 totaling approximately $22,819,000 during the period from March 31, 2021 through September 30,2021. Because of the inherent uncertainty of valuation, estimated values using Level 3 inputs may be materially higher or lower than the values that would have been used had a ready market for investments existed. Accordingly, the degree of judgement exercised by the Company in determining fair value is greatest for investments categorized in Level 3.

Description of Organization and Business Operations
Description of Organization and Business Operations	NOTE 1. DESCRIPTION OF ORGANIZATION AND BUSINESS OPERATIONS ​ MCAP Acquisition Corporation (the “Company”) is a blank check company incorporated in Delaware on November 12, 2020. The Company was formed for the purpose of effectuating a merger, capital stock exchange, asset acquisition, stock purchase, reorganization or other similar business combination with one or more businesses (the “Business Combination”). The Company is an early stage and emerging growth company and, as such, the Company is subject to all of the risks associated with early stage and emerging growth companies. ​ All activity for the period November 12, 2020 (inception) through March 2, 2021 relates to the Company’s formation and the initial public offering (the “Initial Public Offering”), which is described in Note 3. ​ The registration statement for the Company’s Initial Public Offering was declared effective on February 25, 2021. On March 2, 2021, the Company consummated the Initial Public Offering of 31,625,000 units (“Units” and, with respect to the shares of Class A common stock included in the Units offered, the “Public Shares”), generating gross proceeds of $316,250,000 , which is described in Note 3. ​ Simultaneously with the closing of the Initial Public Offering, the Company consummated the sale of 5,983,333 private placement warrants (the “Private Placement Warrants”) at a price of $1.50 per warrant in a private placement to MCAP Acquisition, LLC (the “Sponsor”), generating gross proceeds of $8,975,000 , which is described in Note 4. ​ Following the closing of the Initial Public Offering on March 2, 2021, an amount of $316,250,000 ( $10.00 per Unit) from the net proceeds of the sale of the Units in the Initial Public Offering and the Private Placement Warrants was placed in a trust account (“Trust Account”) which may be invested in U.S. government securities, within the meaning set forth in Section 2(a)(16) of the Investment Company Act of 1940, as amended (the “Investment Company Act”), with a maturity of 185 days or less or in any open-ended investment company that holds itself out as a money market fund meeting the conditions of Rule 2a-7 of the Investment Company Act, as determined by the Company, until the earlier of: (i) the consummation of a Business Combination or (ii) the distribution of the Trust Account to the Company’s stockholders, as described below. ​ Transaction costs amounted to $17,853,629 consisting of $6,325,000 of underwriting fees, $11,068,750 of deferred underwriting fees (see Note 6) and $459,879 of other costs. In addition, $2,431,242 of cash was held outside of the Trust Account and is available for working capital purposes. ​ The Company’s management has broad discretion with respect to the specific application of the net proceeds of the Initial Public Offering and the sale of the Private Placement Warrants, although substantially all of the net proceeds are intended to be applied generally toward consummating a Business Combination. NASDAQ rules provide that the Business Combination must be with one or more target businesses that together have a fair market value equal to at least 80% of the balance in the Trust Account (as defined below) (less any deferred underwriting commissions and taxes payable on interest earned on the Trust Account) at the time of the signing of a definitive agreement to enter a Business Combination. The Company will only complete a Business Combination if the post-Business Combination company owns or acquires 50% or more of the outstanding voting securities of the target or otherwise acquires a controlling interest in the target sufficient for it not to be required to register as an investment company under the Investment Company Act. There is no assurance that the Company will be able to successfully effect a Business Combination. ​ The Company will provide its holders of the outstanding 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 either (i) in connection with a stockholder meeting called to approve the Business Combination or (ii) by means of a tender offer. In connection with a proposed Business Combination, the Company may seek stockholder approval of a Business Combination at a meeting called for such purpose at which stockholders may seek to redeem their shares, regardless of whether they vote for or against a Business Combination. The Company will proceed with a Business Combination only if the Company has net tangible assets of at least $5,000,001 either immediately prior to or upon such consummation of a Business Combination and, if the Company seeks stockholder approval, a majority of the outstanding shares voted are voted in favor of the Business Combination. ​ NOTE 1. DESCRIPTION OF ORGANIZATION AND BUSINESS OPERATIONS (cont.) ​ If the Company seeks stockholder approval of a Business Combination and it does not conduct redemptions pursuant to the tender offer rules, the Company’s Amended and Restated Certificate of Incorporation provides that a public stockholder, together with any affiliate of such stockholder or any other person with whom such stockholder is acting in concert or as a “group” (as defined under Section 13 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”)), will be restricted from seeking redemption rights with respect to 15% or more of the Public Shares without the Company’s prior written consent. ​ The public stockholders will be entitled to redeem their shares for a pro rata portion of the amount then in the Trust Account (initially $10.00 per 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 amount to be distributed to stockholders who redeem their shares will not be reduced by the deferred underwriting commissions the Company will pay to the underwriter (as discussed in Note 6). There will be no redemption rights upon the completion of a Business Combination with respect to the Company’s warrants. These shares of Class A common stock will be recorded at a redemption value and classified as temporary equity upon the completion of the Initial Public Offering, in accordance with Accounting Standards Codification (“ASC”) Topic 480 “Distinguishing Liabilities from Equity.” ​ If a stockholder vote is not required and the Company does not decide to hold a stockholder vote for business or other legal reasons, the Company will, pursuant to its Amended and Restated Certificate of Incorporation, offer such redemption pursuant to the tender offer rules of the Securities and Exchange Commission (the “SEC”), and file tender offer documents containing substantially the same information as would be included in a proxy statement with the SEC prior to completing a Business Combination. ​ The Company’s Sponsor has agreed (a) to vote its Founder Shares (as defined in Note 5) and any Public Shares purchased during or after the Initial Public Offering in favor of a Business Combination, (b) not to propose an amendment to the Company’s Amended and Restated Certificate of Incorporation with respect to the Company’s pre-Business Combination activities prior to the consummation of a Business Combination unless the Company provides dissenting public stockholders with the opportunity to redeem their Public Shares in conjunction with any such amendment; (c) not to redeem any shares (including the Founder Shares) and Private Placement Warrants into the right to receive cash from the Trust Account in connection with a stockholder vote to approve a Business Combination (or to sell any shares in a tender offer in connection with a Business Combination if the Company does not seek stockholder approval in connection therewith) or a vote to amend the provisions of the Amended and Restated Certificate of Incorporation relating to stockholders’ rights of pre-Business Combination activity and (d) that the Founder Shares and Private Placement Warrants shall not participate in any liquidating distributions upon winding up if a Business Combination is not consummated. However, the Sponsor will be entitled to liquidating distributions from the Trust Account with respect to any Public Shares purchased during or after the Initial Public Offering if the Company fails to complete its Business Combination. ​ The Company will have until March 2, 2023 to consummate a Business Combination. If the Company is unable to complete a Business Combination within 24 months from the closing of the Initial Public Offering (the “Combination Period”), the Company will (i) cease all operations except for the purpose of winding up, (ii) as promptly as reasonably possible but no more than ten business days thereafter, redeem the public shares, at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account, including interest earned on the funds held in the Trust Account and not previously released to the Company to pay taxes (less up to $100,000 of interest to pay dissolution expenses), divided by the number of then outstanding public shares, which redemption will completely extinguish public stockholders’ rights as stockholders (including the right to receive further liquidation distributions, if any), subject to applicable law, and (iii) as promptly as reasonably possible following such redemption, subject to the approval of the remaining stockholders and the Company’s board of directors, proceed to commence a voluntary liquidation and thereby a formal dissolution of the Company, subject in each case to its obligations under Delaware law to provide for claims of creditors and the requirements of applicable law. The underwriter has agreed to waive its rights to the deferred underwriting commission held in the Trust Account in the event the Company does not complete a Business Combination within the Combination Period and, in such event, such amounts will be included with the funds held in the Trust Account that will be available to fund the redemption of the Public Shares. In the event of such distribution, it is possible that the per share value of the assets remaining available for distribution will be less than the Initial Public Offering price per Unit ( $10.00 ). There will be no redemption rights or liquidating distributions with respect to the Founder Shares (as defined below) or the Private Placement Warrants, which will expire worthless if the Company fails to complete a Business Combination within the 24 -month time period. NOTE 1. DESCRIPTION OF ORGANIZATION AND BUSINESS OPERATIONS (cont.) ​ The Sponsor has agreed that it will be liable to the Company if and to the extent any claims by a third party for services rendered or products sold to the Company, or a prospective target business with which the Company has entered into a written letter of intent, confidentiality or similar agreement or Business Combination agreement, reduce the amount of funds in the Trust Account to below the lesser of (i) $10.00 per Public Share and (ii) the actual amount per Public Share held in the Trust Account as of the day of liquidation of the Trust Account, if less than $10.00 per share due to reductions in the value of the trust assets, less taxes payable, provided that such liability will not apply to any claims by a third party or prospective target business who executed a waiver of any and all rights to monies held in the Trust Account (whether or not such waiver is enforceable) nor will it apply to any claims under the Company’s indemnity of the underwriter of Initial Public Offering against certain liabilities, including liabilities under the Securities Act of 1933, as amended (the “Securities Act”). However, the Company has not asked the Sponsor to reserve for such indemnification obligations, nor has the Company independently verified whether the Sponsor has sufficient funds to satisfy its indemnity obligations and believe that the Sponsor’s only assets are securities of the Company. Therefore, the Company cannot assure its stockholders that the Sponsor would be able to satisfy those obligations. None of the Company’s officers or directors will indemnify the Company for claims by third parties including, without limitation, claims by vendors and prospective target businesses. The Company will seek to reduce the possibility that the Sponsor will have to indemnify the Trust Account due to claims of creditors by endeavoring to have all vendors, service providers, prospective target businesses or other entities with which the Company does business, execute agreements with the Company waiving any right, title, interest or claim of any kind in or to monies held in the Trust Account. ​ Management is currently evaluating the impact of the COVID-19 pandemic and has concluded that while it is reasonably possible that the virus could have a negative effect on the Company’s financial position, results of its operations and/or search for a target company, the specific impact is not readily determinable as of the date of the financial statement. The financial statement does not include any adjustments that might result from the outcome of this uncertainty. ​ Going Concern and Management’s Plans ​ The accompanying financial statement has been prepared on a going concern basis, which contemplates the realization of assets and the satisfaction of liabilities in the normal course of business. The Company’s management believes that its operations may not be sufficient to fund operating cash needs for at least 12 months from the issuance of this financial statement. The Company has no significant assets and has no revenue generating operations. There can be no assurance that the Company will be able to raise additional capital when needed, or at terms deemed acceptable, if at all. These factors raise substantial doubt about the Company’s ability to continue as a going concern for at least 12 months from the issuance of this financial statement. The accompanying financial statement does not include any adjustments relating to the recoverability and classification of asset carrying amounts or the amount and classification of liabilities that might result should the Company be unable to continue as a going concern. ​	MCAP ACQUISITION CORPORATION NOTES TO FINANCIAL STATEMENTS NOTE 1. DESCRIPTION OF ORGANIZATION AND BUSINESS OPERATIONS MCAP Acquisition Corporation (the “Company”) is a blank check company incorporated in Delaware on November 12, 2020. The Company was formed for the purpose of effectuating a merger, capital stock exchange, asset acquisition, stock purchase, reorganization or other similar business combination with one or more businesses (the “Business Combination”).The Company is an early stage and emerging growth company and, as such, the Company is subject to all of the risks associated with early stage and emerging growth companies. As of December 31, 2020, the Company had not yet commenced any operations. All activity for the period November 12, 2020 (inception) through December 31, 2020 relates to the Company’s formation and the proposed initial public offering (the “Proposed Offering”). The Company has selected December 31 as its fiscal year end. The Company’s ability to commence operations is contingent upon obtaining adequate financial resources through a proposed initial public offering of 27,500,000 units at $10.00 per unit (or 31,625,000 units if the underwriter’s over-allotment option is exercised in full) (the “Units” and, with respect to the shares of Class A common stock included in the Units being offered, the “Public Shares”) which is discussed in Note 3 and the sale of 5,433,333 warrants (or 5,983,333 warrants if the underwriter’s over-allotment option is exercised in full) (the “Private Placement Warrants”) at a price of $1.50 per Private Placement Warrant that will close in a private placement to MCAP Acquisition, LLC (the “Sponsor”) simultaneously with the closing of the Proposed Offering (see Note 4). The Company’s management has broad discretion with respect to the specific application of the net proceeds of the Proposed Offering and the sale of the Private Placement Warrants, although substantially all of the net proceeds are intended to be applied generally toward consummating a Business Combination. NASDAQ rules provide that the Business Combination must be with one or more target businesses that together have a fair market value equal to at least 80% of the balance in the Trust Account (as defined below) (less any deferred underwriting commissions and taxes payable on interest earned on the Trust Account) at the time of the signing a definitive agreement to enter a Business Combination.

There is no assurance that the Company will be able to successfully effect a Business Combination. Upon the closing of the Proposed Offering, management has agreed that $10.00 per Unit sold in the Proposed Offering, including the proceeds from the sale of the Private Placement Warrants, will be held in a trust account (the “Trust Account”) and invested in U.S. government securities, within the meaning set forth in Section 2(a)(16) of the Investment Company Act, with a maturity of 185 days or less, or in any open-ended investment company that holds itself out as a money market fund meeting the conditions of Rule 2a-7 of the Investment Company Act, as determined by the Company, until the earlier of: (i) the consummation of a Business Combination or (ii) the distribution of the funds in the Trust Account to the Company’s stockholders, as described below.

Going Concern Consideration At December 31, 2020, the Company had $25,000 in cash and working capital deficit of $140,584. The Company has incurred and expects to continue to incur significant costs in pursuit of its financing and acquisition plans. These conditions raise substantial doubt about the Company’s ability to continue as a going concern for a period of time within one year after the date that the financial statements are issued. Management plans to address this uncertainty through the Proposed Offering as discussed in Note 3. There is no assurance that the Company’s plans to raise capital or to consummate a Business Combination will be successful or successful within the Combination Period. The financial statements do not include any adjustments that might result from the outcome of this uncertainty.	Note 1 — Description of Organization and Business Operations MCAP Acquisition Corporation (the “Company”) is a blank check company incorporated in Delaware on November 12, 2020. The Company was formed for the purpose of effectuating a merger, capital stock exchange, asset acquisition, stock purchase, reorganization or other similar business combination with one or more businesses (the “Business Combination”). The Company is an early stage and emerging growth company and, as such, the Company is subject to all of the risks associated with early stage and emerging growth companies. The accompanying condensed consolidated financial statements includes the Company and its wholly owned subsidiaries GRNT Merger Sub 1 LLC, GRNT Merger Sub 2 LLC, GRNT Merger Sub 3 LLC, and GRNT Merger Sub 4 LLC. As of September 30, 2021, the Company had not yet commenced any operations. All activity for the period November 12, 2020 (inception) through September 30, 2021 relates to the Company’s formation, initial public offering (the “Initial Public Offering”) and search to effectuate a Business Combination. The Company has selected December 31 as its fiscal year end. The registration statement for the Company’s Initial Public Offering was declared effective on February 25, 2021. On March 2, 2021, the Company consummated the Initial Public Offering of 31,625,000 units (“Units” and, with respect to the shares of Class A common stock included in the Units offered, the “Public Shares”), generating gross proceeds of $316,250,000, which is described in Note 3. Simultaneously with the closing of the Initial Public Offering, the Company consummated the sale of 5,983,333 private placement warrants (the “Private Placement Warrants”) at a price of $1.50 per warrant in a private placement to MCAP Acquisition, LLC (the “Sponsor”), generating gross proceeds of $8,975,000, which is described in Note 4. Following the closing of the Initial Public Offering on March 2, 2021, an amount of $316,250,000 ($10.00 per Unit) from the net proceeds of the sale of the Units in the Initial Public Offering and the Private Placement Warrants was placed in a trust account (“Trust Account”) which may be invested in U.S. government securities, within the meaning set forth in Section 2(a)(16) of the Investment Company Act of 1940, as amended (the “Investment Company Act”), with a maturity of 185 days or less or in any open-ended investment company that holds itself out as a money market fund meeting the conditions of Rule 2a-7 of the Investment Company Act, as determined by the Company, until the earlier of: (i) the consummation of a Business Combination or (ii) the distribution of the Trust Account to the Company’s stockholders, as described below. Transaction costs of the Initial Public Offering amounted to $17,853,629 consisting of $6,325,000 of underwriting fees, $11,068,750 of deferred underwriting fees (see Note 6) and $459,879 of other costs. Following the closing of the Initial Public Offering $2,431,242 of cash was held outside of the Trust Account available for working capital purposes. As of September 30, 2021, we have available to us $797,602 of cash on our balance sheet and a working capital surplus of $706,131. The Company’s management has broad discretion with respect to the specific application of the net proceeds of the Initial Public Offering and the sale of the Private Placement Warrants, although substantially all of the net proceeds are intended to be applied generally toward consummating a Business Combination. NASDAQ rules provide that the Business Combination must be with one or more target businesses that together have a fair market value equal to at least 80% of the balance in the Trust Account (as defined below) (less any deferred underwriting commissions and taxes payable on interest earned on the Trust Account) at the time of the signing of a definitive agreement to enter a Business Combination.

There is no assurance that the Company will be able to successfully effect a Business Combination. ​ Note 1 — Description of Organization and Business Operations (continued) The Company will provide its holders of the outstanding 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 either (i) in connection with a stockholder meeting called to approve the Business Combination or (ii) by means of a tender offer.

As of September 30, 2021, we had incurred accumulated losses of approximately $2,915,213 for the period from November 12, 2020 (date of inception) through September 30, 2021. The Company’s management believes that its operations may not be sufficient to fund operating cash needs for at least 12 months from the issuance of these financial statements. The Company has no significant assets and has no revenue generating operations. There can be no assurance however that the Company will be able to raise additional capital when needed, or at terms deemed acceptable, if at all. These factors raise substantial doubt about the company’s ability to continue as a going concern within one year after the date that the unaudited condensed financial statements are issued. The unaudited condensed consolidated financial statements do not include any adjustments relating to the recoverability and classification of asset carrying amounts or the amount and classification of liabilities that might result should the Company be unable to continue as a going concern. Risks and Uncertainties Management is currently evaluating the impact of the COVID-19 pandemic and has concluded that while it is reasonably possible that the virus could have a negative effect on the Company’s financial position, results of its operations and/or search for a target company, the specific impact is not readily determinable as of the date of the financial statement. The financial statements do not include any adjustments that might result from the outcome of this uncertainty.

SUMMARY OF SIGNIFICANT ACCOUN_9

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	Mar. 02, 2021	Dec. 31, 2020	Sep. 30, 2021
Summary of Significant Accounting Policies
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	NOTE 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES ​ Basis of Presentation ​ The accompanying balance sheet has been prepared in conformity with accounting principles generally accepted in the United States of America (“GAAP”) and pursuant to the rules and regulations of the SEC. ​ 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 independent registered public accounting firm attestation requirements of Section 404 of the Sarbanes-Oxley Act, 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. ​ NOTE 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (cont.) ​ 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 a company can elect to opt out of the extended transition period and comply with the requirements that apply to non-emerging growth companies but any such election to opt out is irrevocable. The Company has elected not to opt out of such 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 emerging growth company, can adopt the new or revised standard at the time private companies adopt the new or revised standard. This may make comparison of the Company’s financial statements with another public company, which is neither an emerging growth company nor an emerging growth company which has opted out of using the extended transition period difficult or impossible because of the potential differences in accounting standards used. ​ Use of Estimates ​ The preparation of the balance sheet 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 financial statements and the reported amounts of revenues and 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 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 highly liquid investments purchased with an original maturity of three months or less to be cash equivalents. Cash equivalents are carried at cost, which approximates fair value. The Company had $2,431,242 in cash and no cash equivalents as of March 2, 2021. ​ 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 recognizes accrued interest and penalties related to unrecognized tax benefits, if any, as income tax expense. There were no unrecognized tax benefits and no amounts accrued for interest and penalties as of March 2, 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. ​ NOTE 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (cont.) ​ Class A Common Stock Subject to Possible Redemption ​ The Company accounts for its shares subject to possible redemption in accordance with the guidance in Accounting Standards Codification (“ASC”) Topic 480 “Distinguishing Liabilities from Equity.” Shares subject to mandatory redemption (if any) is classified as a liability instrument and is measured at fair value. Conditionally redeemable shares of common stock (including shares of common stock that feature redemption rights that are 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, shares are classified as stockholders’ equity. The Company’s shares feature certain redemption rights that are considered to be outside of the Company’s control and subject to occurrence of uncertain future events. Accordingly, at March 2, 2021, shares subject to possible redemption are presented as temporary equity, outside of the stockholders’ equity section of the Company’s balance sheet. ​ Offering Costs ​ Offering costs consist of legal, accounting, underwriting fees and other costs incurred through the balance sheet date that are directly related to the Initial Public Offering. Offering costs amounting to $17,853,629 were charged to stockholders’ equity upon the completion of the Initial Public Offering. ​ Cash Held in Trust Account ​ At March 2, 2021, the assets held in the Trust Account were held in cash. ​ Concentration 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 Depository Insurance Corporation coverage limit of $250,000 . The Company has not experienced losses on this account and management believes the Company is not exposed to significant risks on such account. ​ Fair Value of Financial Instruments ​ The fair value of the Company’s assets and liabilities, which qualify as financial instruments under ASC Topic 820, “Fair Value Measurement,” approximates the carrying amounts represented in the accompanying balance sheet, primarily due to their short-term nature. ​ Derivative Financial Instruments The Company evaluates its financial instruments to determine if such instruments are derivatives or contain features that qualify as embedded derivatives in accordance with ASC Topic 815, “Derivatives and Hedging”. For derivative financial instruments that are accounted for as liabilities, the derivative instrument is initially recorded at its fair value on the grant date and is then re-valued at each reporting date, with changes in the fair value reported in the statements of operations. The classification of derivative instruments, including whether such instruments should be recorded as liabilities or as equity, is evaluated at the end of each reporting period. Derivative liabilities are classified in the balance sheet as current or non-current based on whether or not net-cash settlement or conversion of the instrument could be required within 12 months of the balance sheet date. ​ Recently Issued Accounting Standards ​ 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 financial statements. ​	NOTE 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Basis of Presentation The accompanying 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. 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 independent registered public accounting firm attestation requirements of Section 404 of the Sarbanes-Oxley Act, 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 a company can elect to opt out of the extended transition period and comply with the requirements that apply to non-emerging growth companies but any such election to opt out is irrevocable. The Company has elected not to opt out of such 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 emerging growth company, can adopt the new or revised standard at the time private companies adopt the new or revised standard. This may make comparison of the Company’s financial statements with another public company, which is neither an emerging growth company nor an emerging growth company which has opted out of using the extended transition period difficult or impossible because of the potential differences in accounting standards used. Use of Estimates The preparation of 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 financial statements and the reported amounts of revenue and 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 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 did not have any cash equivalents as of December 31, 2020. 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 recognizes accrued interest and penalties related to unrecognized tax benefits, if any, as income tax expense. There were no unrecognized tax benefits and no amounts accrued for interest and penalties as of December 31, 2020. 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 provision for income taxes was deemed to be immaterial for the period from November 12, 2020 (inception) through December 31, 2020. Net Loss Per Common Share Net loss per share of common stock is computed by dividing net loss by the weighted average number of common shares outstanding during the period, excluding common shares subject to forfeiture. Weighted average shares were reduced for the effect of an aggregate of 1,031,250 shares of Class B common stock that are subject to forfeiture if the over-allotment option is not exercised by the underwriter (see Notes 7 and 8). At December 31, 2020, 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. As a result, diluted loss per share is the same as basic loss per share for the period presented. Concentration 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 Depository Insurance Corporation coverage limit of $250,000. The Company has not experienced losses on this account and management believes the Company is not exposed to significant risks on such account. Fair Value of Financial Instruments The fair value of the Company’s assets and liabilities, which qualify as financial instruments under ASC Topic 820, “Fair Value Measurement,” approximates the carrying amounts represented in the accompanying balance sheet, primarily due to their short-term nature. Recently Issued Accounting Standards 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 financial statements. Subsequent Events Management of the Company evaluates events that have occurred after the balance sheet date of December 31, 2020 through the date these financial statements were issued. Based upon the review, management did not identify any recognized or non-recognized subsequent events that would have required adjustment or disclosure in the financial statements, except as follows. On February 25, 2021, the Company’s Board of Directors approved a stock dividend of 718,750 shares of Class B common stock (the “Stock Dividend”). The par values of the common and preferred stock were not adjusted as a result of the Stock Dividend. All references to common stock, warrants to purchase common stock, share data, per share data, and related information contained in the financial statements have been retroactively adjusted to reflect this Stock Dividend for all periods presented.	Note 2 — Summary of Significant Accounting Policies Basis of Presentation The accompanying financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“US GAAP”) and pursuant to the accounting and disclosure rules and regulations of the U.S. Securities and Exchange Commission. In preparation of the Company’s unaudited condensed consolidated financial statements as of and for quarterly period ended September 30, 2021, the Company concluded it will restate its financial statements to classify all Class A common shares as Class A common stock subject to possible redemption in temporary equity as of September 30, 2021 (see Note 11). 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 independent registered public accounting firm attestation requirements of Section 404 of the Sarbanes-Oxley Act, 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. ​ Note 2 — Summary of Significant Accounting Policies (continued) 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.

Cash and Cash Equivalents The Company considers all highly liquid investments purchased with an original maturity of three months or less to be cash equivalents. Cash equivalents are carried at cost, which approximates fair value. The Company had $797,602 in cash and no cash equivalents as of September 30, 2021. 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.

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 recognizes accrued interest and penalties related to unrecognized tax benefits, if any, as income tax expense. There were no unrecognized tax benefits and no amounts accrued for interest and penalties as of September 30, 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 provision for income taxes was deemed to be immaterial for the three and nine months ended September 30, 2021. ​ Note 2 — Summary of Significant Accounting Policies (continued) Class A Common Stock Subject to Possible Redemption The Company accounts for its shares subject to possible redemption in accordance with the guidance in Accounting Standards Codification (“ASC”) Topic 480 “Distinguishing Liabilities from Equity.” Shares subject to mandatory redemption (if any) is classified as a liability instrument and is measured at fair value. Conditionally redeemable shares of common stock (including shares of common stock that feature redemption rights that are 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, shares are classified as stockholders’ equity. The Company’s shares feature certain redemption rights that are considered to be outside of the Company’s control and subject to occurrence of uncertain future events. Accordingly, at September 30, 2021, 31,625,000 shares of Class A Common Stock subject to possible redemption are presented as temporary equity, outside of the stockholders’ equity section of the Company’s balance sheet. Cash Held in Trust Account At September 30, 2021, the assets held in the Trust Account were invested in a money market fund. Concentration 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 Depository Insurance Corporation coverage limit of $250,000. The Company has not experienced losses on this account and management believes the Company is not exposed to significant risks on such account. Net Loss Per Share The Company complies with accounting and disclosure requirements of FASB ASC Topic 260, Earnings Per Share. Net loss per share is computed by dividing net income by the weighted average number of shares of common stock outstanding during the period. The Company has two classes of shares, Class A common stock and Class B common stock. Earnings and losses are shared pro rata between the two classes of common stock. The Company has not considered the effect of warrants sold in the Initial Public Offering and the private placement to purchase common stock in the calculation of diluted income per share, since the exercise of the warrants is contingent upon the occurrence of future events. As a result, diluted net loss per common share is the same as basic net loss per share for the period presented. The Company’s condensed statement of operations applies the two-class method in calculating net income per share. Basic and diluted net loss per share for Class A common stock and Class B common stock is calculated by dividing net loss attributable to the Company by the weighted average number of shares of Class A common stock and Class B common stock outstanding, allocated proportionally to each class of common stock. ​ Note 2 — Summary of Significant Accounting Policies (continued) The following table reflects the calculation of basic and diluted net loss per ordinary share (in dollars, except per share amounts): ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ For the Three ​ For the ​ ​ Three Months Ended ​ Nine Months Ended ​ ​ September 30, ​ September 30, ​ 2021 2021 Class A common stock ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Net loss allocable to Class A common stock ​ $ (3,680,202) ​ $ (2,193,437) ​ ​ ​ ​ ​ ​ ​ Basic and diluted weighted ​ ​ 31,625,000 ​ ​ 24,674,451 Basic and diluted net ​ $ (0.12) ​ $ (0.09) Non-Redeemable Class B common stock ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Net loss allocable to Class B common stock ​ $ (920,051) ​ $ (702,826) ​ ​ ​ ​ ​ ​ ​ Basic and diluted weighted ​ ​ 7,906,250 ​ ​ 7,906,250 Basic and diluted net ​ $ (0.12) ​ $ (0.09) ​ Fair Value of Financial Instruments The fair value of the Company’s assets and liabilities, which qualify as financial instruments under ASC Topic 820, “Fair Value Measurement,” approximates the carrying amounts represented in the accompanying balance sheet, primarily due to their short-term nature.

There were no unrecognized tax benefits and no amounts accrued for interest and penalties as of September 30, 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 provision for income taxes was deemed to be immaterial for the three and nine months ended September 30, 2021.
Net Loss Per Common Share		Net Loss Per Common Share Net loss per share of common stock is computed by dividing net loss by the weighted average number of common shares outstanding during the period, excluding common shares subject to forfeiture. Weighted average shares were reduced for the effect of an aggregate of 1,031,250 shares of Class B common stock that are subject to forfeiture if the over-allotment option is not exercised by the underwriter (see Notes 7 and 8). At December 31, 2020, 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. As a result, diluted loss per share is the same as basic loss per share for the period presented.	Net Loss Per Share The Company complies with accounting and disclosure requirements of FASB ASC Topic 260, Earnings Per Share. Net loss per share is computed by dividing net income by the weighted average number of shares of common stock outstanding during the period. The Company has two classes of shares, Class A common stock and Class B common stock. Earnings and losses are shared pro rata between the two classes of common stock. The Company has not considered the effect of warrants sold in the Initial Public Offering and the private placement to purchase common stock in the calculation of diluted income per share, since the exercise of the warrants is contingent upon the occurrence of future events. As a result, diluted net loss per common share is the same as basic net loss per share for the period presented. The Company’s condensed statement of operations applies the two-class method in calculating net income per share. Basic and diluted net loss per share for Class A common stock and Class B common stock is calculated by dividing net loss attributable to the Company by the weighted average number of shares of Class A common stock and Class B common stock outstanding, allocated proportionally to each class of common stock. The following table reflects the calculation of basic and diluted net loss per ordinary share (in dollars, except per share amounts): ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ For the Three ​ For the ​ ​ Three Months Ended ​ Nine Months Ended ​ ​ September 30, ​ September 30, ​ 2021 2021 Class A common stock ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Net loss allocable to Class A common stock ​ $ (3,680,202) ​ $ (2,193,437) ​ ​ ​ ​ ​ ​ ​ Basic and diluted weighted ​ ​ 31,625,000 ​ ​ 24,674,451 Basic and diluted net ​ $ (0.12) ​ $ (0.09) Non-Redeemable Class B common stock ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Net loss allocable to Class B common stock ​ $ (920,051) ​ $ (702,826) ​ ​ ​ ​ ​ ​ ​ Basic and diluted weighted ​ ​ 7,906,250 ​ ​ 7,906,250 Basic and diluted net ​ $ (0.12) ​ $ (0.09)

Subsequent Events		Subsequent Events Management of the Company evaluates events that have occurred after the balance sheet date of December 31, 2020 through the date these financial statements were issued.

On February 25, 2021, the Company’s Board of Directors approved a stock dividend of 718,750 shares of Class B common stock (the “Stock Dividend”). The par values of the common and preferred stock were not adjusted as a result of the Stock Dividend. All references to common stock, warrants to purchase common stock, share data, per share data, and related information contained in the financial statements have been retroactively adjusted to reflect this Stock Dividend for all periods presented.

Offering costs amounting to $17,853,629 were charged to stockholders’ equity upon the completion of the Initial Public Offering.
