DESCRIPTION OF ORGANIZATION AND

DESCRIPTION OF ORGANIZATION AND BUSINESS OPERATIONS	Dec. 31, 2020	Sep. 30, 2021
Aldel Financial Inc.
DESCRIPTION OF ORGANIZATION AND BUSINESS OPERATIONS	NOTE 1. DESCRIPTION OF ORGANIZATION AND BUSINESS OPERATIONS Aldel Financial Inc. (the “Company”) is a blank check company incorporated in Delaware on December 23, 2020. The Company was formed for the purpose of merger, share exchange, asset acquisition, stock purchase, recapitalization, reorganization or other similar business combination with one or more businesses or entities (“Business Combination”). Although the Company is not limited to a particular industry or geographic region for purposes of consummating a Business Combination, the Company intends to focus its search for a target business that is exiting the restructuring process or that has transient current ownership. Aldel Financial Inc. will target companies with established operating models that have strong management teams, realigned capital structures, positive cash flows prospects, and a clear and well-defined pathway for growing profitably over the long-term. 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 through December 31, 2020 relates to the Company’s formation and the proposed initial public offering (“Proposed Offering”), which is described below. The Company will not generate any operating revenues until after the completion of its initial Business Combination, at the earliest. The Company will generate nonoperating income in the form of interest income from the proceeds derived from 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 i) the Proposed Offering of 10,000,000 units at $10.00 per unit (or 11,500,000 units if the underwriters’ 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, ii) the sale of 1,300,000 $15.00 exercise price warrants (the “$15 Private Warrants”) at a price of $0.10 per $15 Private Warrant, and iii) the sale of 500,000 units (or 515,000 private units if the over-allotment option is exercised in full) at $10.00 per unit (the “Private Units”) in a private placement. The Company will sell 650,000 of the $15 Private Warrants and all of the 500,000 Private Units (or 515,000 Private units if the over-allotment option is exercised in full) to the Company’s sponsor, Aldel Investors LLC (the “Sponsor”), and remaining 650,000 $15 Private Warrants to FG SPAC Partners LP (“FGSP”), an affiliate of certain of the Company’s directors, in a private placement that will close simultaneously with the Proposed Offering. Each Private Unit will consist of one Class A common share and one-half of one non-redeemable warrant (“Private Unit Warrant”). Each whole Private Unit Warrant will entitle the holder to purchase one share of common stock at an exercise price of $11.50 per share. The Company intends to list the Units on the New York Stock Exchange (“NYSE”). The Company’s management has broad discretion with respect to the specific application of the net proceeds of the Proposed Offering and sale of the $15 Private Warrants and Private Units, although substantially all of the net proceeds are intended to be applied generally toward consummating a Business Combination. NYSE 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 net assets held in the Trust Account (as defined below) (net of amounts disbursed to management for working capital purposes). 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 $10.10 per Unit sold in the Proposed Offering will be held in a trust account (“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 shareholders, as described below. The Company will provide its shareholders 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 shareholder 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 shareholder approval of a Business Combination at a meeting called for such purpose at which shareholders may seek to redeem their shares, regardless of whether they vote for or against the proposed Business Combination. The Company will proceed with a Business Combination only if the Company has net tangible assets of at least $5,000,001 upon or immediately prior to such consummation of a Business Combination and, if the Company seeks shareholder approval, a majority of the outstanding shares voted are voted in favor of the Business Combination. If the Company seeks shareholder 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 will provide that a public shareholder, together with any affiliate of such shareholder or any other person with whom such shareholder 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 holders of Public Shares will be entitled to redeem their Public Shares for a pro rata portion of the amount then in the Trust Account (including 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). There will be no redemption rights upon the completion of a Business Combination with respect to the Company’s warrants. A portion of the Public Shares will be recorded at a redemption value and classified as temporary equity upon the completion of the Proposed Offering, in accordance with Accounting Standard Codification (“ASC”) Topic 480 “Distinguishing Liabilities from Equity” in order for the Company to maintain net tangible assets of at least $5,000,001. If a shareholder vote is not required and the Company does not decide to hold a shareholder 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 (“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 Sponsor, FGSP, officers, directors and advisors (the “Initial Shareholders”) have agreed (a) to vote their Founder Shares (as defined in Note 5) as well as any common shares underlying the Private Units, 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 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 shareholders with the opportunity to redeem their Public Shares in conjunction with any such amendment; (c) not to redeem any shares (including the Founder Shares as well as any common shares underlying the Private Units) into the right to receive cash from the Trust Account in connection with a shareholder 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 shareholder approval in connection therewith) or a vote to amend the provisions of the amended and restated certificate of incorporation relating to shareholders’ rights of pre-Business Combination activity and (d) that the Founder Shares, the Private Units and $15 Private Warrants (including underlying securities) shall not participate in any liquidating distributions upon winding up if a Business Combination is not consummated. However, the Initial Shareholders 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. The Company will have until 18 months from the closing of the Proposed Offering to consummate a Business Combination (as such period may be extended pursuant to the amended and restated certificate of incorporation, the “Combination Period”). If the Company is unable to complete a Business Combination within the Combination Period, the Company will (i) cease all operations except for the purpose of winding up, (ii) as promptly as reasonably possible but 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 vendor for services rendered or products sold to the Company, or a prospective target business with which the Company has discussed entering into a transaction agreement, reduce the amounts in the Trust Account to below $10.10 per share, except as to any claims by a third party who executed a waiver of any and all rights to seek access to the Trust Account and except as to any claims under the Company’s indemnity of the underwriters of the Proposed Offering against certain liabilities, including liabilities under the Securities Act of 1933, as amended (the “Securities Act”). In the event that an executed waiver is deemed to be unenforceable against a third party, the Sponsor will not be responsible to the extent of any liability for such third-party claims. 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 no cash and working capital deficit of $56,470. The Company has incurred and expects to continue to incur significant costs in pursuit of its Proposed Offering and Business Combination plans. These conditions raise substantial doubt about the Company’s ability to continue as a going concern within one year after the date that the financial statements are issued. Management plans to address this uncertainty through a Proposed Offering as discussed in Note 3, as well as sale of $15 Private Warrants and Private Units as discussed above. 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. Subsequent to December 31, 2020, the Sponsor has agreed to loan the Company an aggregate amount of $225,000 and FG SPAC Solutions LLC (“FGSS”), an affiliate of certain of the Company’s directors, has agreed to loan the Company an aggregate amount of $25,000 to be used, in part, for transaction costs incurred in connection with the Proposed Offering (the “Promissory Notes”). As of December 31, 2020, there was not any balance outstanding under the Promissory Notes (see Note 5). 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 Aldel Financial Inc. (the “Company” or “Aldel”) is a blank check company incorporated in Delaware on December 23, 2020. The Company was formed for the purpose of merger, share exchange, asset acquisition, stock purchase, recapitalization, reorganization or other similar business combination with one or more businesses or entities (“Business Combination”). Although the Company is not limited to a particular industry or geographic region for purposes of consummating a Business Combination, the Company intends to focus its search for a target business on companies that are exiting the restructuring process or that have transient current ownership. Aldel Financial Inc. will target companies with established operating models that have strong management teams, realigned capital structures, positive cash flows prospects, and a clear and well-defined pathway for growing profitably over the long-term. 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 September 30, 2021, the Company had not yet commenced any operations. All activity through September 30, 2021 relates to the Company’s formation and the initial public offering (“IPO”), which is described below. The Company will not generate any operating revenues until after the completion of its initial Business Combination, at the earliest. The Company will generate nonoperating income in the form of interest income from the proceeds derived from the IPO. The Company has selected December 31 as its fiscal year end. Aldel Merger Sub LLC is a wholly- owned subsidiary of the Company and currently has no operations. The registration statement for the Company’s IPO was declared effective on April 8, 2021. On April 12, 2021, the Company consummated its IPO of 11,500,000 units (the “Units”), including 1,500,000 Units that were issued pursuant to the underwriters’ full exercise of their over-allotment option. Each Unit consists of one share of Class A common stock of the Company, par value $0.0001 per share (the “Public Share”) and one-half of one redeemable warrant (“Public Warrant”), each whole Public Warrant entitling the holder thereof to purchase one share of common stock for $11.50 per share. The Units were sold at a price of $10.00 per Unit, generating gross proceeds to the Company of $115,000,000. The Public Warrants will become exercisable on the later of 30 days after the completion of Business Combination and 12 months from the closing of the IPO, and will expire five years after the completion of Business Combination or earlier upon Company’s liquidation. Simultaneously with the closing of the IPO, the Company consummated private placements (the “Private Placements”) in which (i) Aldel Investors LLC (the “Sponsor”) purchased 515,000 private units (the “Private Units”) at a price of $10.00 per Private Unit, generating total proceeds of $5,150,000, and (ii) the Sponsor and FG SPAC Partners LP (“FGSP”) purchased an aggregate of 1,300,000 warrants (“OTM Warrants” and, together with the Private Units, the “Private Placement Securities”) at a price of $0.10 per warrant, each exercisable to purchase one share of Class A common stock at $15.00 per share, for an aggregate purchase price of $130,000. Each Private Unit consists of one Common Stock and one-half of one non-redeemable warrant (“Private Unit Warrant”). Each whole Private Unit Warrant will entitle the holder to purchase one share of Common Stock at an exercise price of $11.50 per share. The Private Unit Warrants have terms similar to the Public Warrants, except that the Private Unit Warrants will be non-redeemable and may be exercised on a cashless basis so long as they continue to be held by the initial shareholders or their permitted transferees. Additionally, Private Unit Warrants and the shares issuable upon the exercise of the Private Unit Warrants will not be transferable, assignable or salable until after the completion of a Business Combination. The OTM Warrants will entitle the holder to purchase one share of Common Stock at an exercise price of $15.00 per each share, will be exercisable for a period of 10 years from the date of Business Combination, will be non-redeemable, and may be exercised on a cashless basis so long as they continue to be held by the initial shareholders or their permitted transferees. Additionally, OTM Warrants and the shares issuable upon the exercise of the OTM Warrants will not be transferable, assignable or salable until after the completion of a Business Combination. The Company’s Units are listed on the New York Stock Exchange (“NYSE”). The Company’s management has broad discretion with respect to the specific application of the net proceeds of the IPO and sale of the Private Placement Securities, although substantially all of the net proceeds are intended to be applied generally toward consummating a Business Combination. NYSE 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 net assets held in the Trust Account (as defined below). 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. Following the closing of the IPO on April 12, 2021, an amount of $116,150,000 ($10.10 per Unit) from the net proceeds of the sale of Units in the IPO and the sale of Private Placement Securities were placed in a trust account (“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 shareholders, as described below. The Company will provide its shareholders 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 shareholder 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 shareholder approval of a Business Combination at a meeting called for such purpose at which shareholders may seek to redeem their shares, regardless of whether they vote for or against the proposed Business Combination. The Company will proceed with a Business Combination only if the Company has net tangible assets of at least $5,000,001 upon or immediately prior to such consummation of a Business Combination and, if the Company seeks shareholder approval, a majority of the outstanding shares voted are voted in favor of the Business Combination. If the Company seeks shareholder 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 will provide that a public shareholder, together with any affiliate of such shareholder or any other person with whom such shareholder 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 holders of Public Shares will be entitled to redeem their Public Shares for a pro rata portion of the amount then in the Trust Account (including 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). There will be no redemption rights upon the completion of a Business Combination with respect to the Company’s warrants. If a shareholder vote is not required and the Company does not decide to hold a shareholder 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 (“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 Sponsor, FGSP, officers, directors and advisors (the “Initial Shareholders”) have agreed (a) to vote their Founder Shares (as defined in Note 6) as well as any common shares underlying the Private Units, and any Public Shares purchased during or after the IPO 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 shareholders with the opportunity to redeem their Public Shares in conjunction with any such amendment; (c) not to redeem any shares (including the Founder Shares as well as any common shares underlying the Private Units) into the right to receive cash from the Trust Account in connection with a shareholder 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 shareholder approval in connection therewith) or a vote to amend the provisions of the amended and restated certificate of incorporation relating to shareholders’ rights of pre-Business Combination activity and (d) that the Founder Shares, the Private Units and OTM Warrants (including underlying securities) shall not participate in any liquidating distributions upon winding up if a Business Combination is not consummated. However, the Initial Shareholders will be entitled to liquidating distributions from the Trust Account with respect to any Public Shares purchased during or after the IPO if the Company fails to complete its Business Combination. The Company will have until 18 months from the closing of the IPO to consummate a Business Combination (as such period may be extended pursuant to the amended and restated certificate of incorporation, the “Combination Period”). If the Company is unable to complete a Business Combination within the Combination Period, the Company will (i) cease all operations except for the purpose of winding up, (ii) as promptly as reasonably possible but 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 vendor for services rendered or products sold to the Company, or a prospective target business with which the Company has discussed entering into a transaction agreement, reduce the amounts in the Trust Account to below $10.10 per share, except as to any claims by a third party who executed a waiver of any and all rights to seek access to the Trust Account and except as to any claims under the Company’s indemnity of the underwriters of the Offering against certain liabilities, including liabilities under the Securities Act of 1933, as amended (the “Securities Act”). In the event that an executed waiver is deemed to be unenforceable against a third party, the Sponsor will not be responsible to the extent of any liability for such third-party claims. 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 considerations As of September 30, 2021, the Company has approximately $407,664 in its bank account and working capital surplus of approximately $1.1 million. Company does not believe it will need to raise additional funds in order to meet the expenditures required for operating the business. However, if the estimate of the costs of identifying a target business, undertaking in-depth due diligence and negotiating a Business Combination are less than the actual amount necessary to do so, Company may have insufficient funds available to operate the business prior to the initial Business Combination. In order to finance transaction costs in connection with a Business Combination, the Sponsor or an affiliate of the Sponsor, or certain of our officers and directors may, but are not obligated to, loan the funds to the Company as may be required.

SUMMARY OF SIGNIFICANT ACCOUNTI

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	Dec. 31, 2020	Sep. 30, 2021
Aldel Financial Inc.
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	NOTE 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Basis of presentation The accompanying financial statements are presented in U.S. Dollars and 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 auditor 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 shareholder 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 revenues and expenses during the reporting periods. 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 or cash equivalents as of December 31, 2020. Deferred offering costs Deferred offering costs consist of underwriting and legal expenses incurred through the balance sheet date that are directly related to the Proposed Offering and that will be charged to shareholders equity upon the completion of the Proposed Offering. Should the Proposed Offering prove to be unsuccessful, these deferred costs, as well as additional expenses incurred, will be charged to operations. 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 as of December 31, 2020 and no amounts accrued for interest and penalties. The Company is currently not aware of any issues under review that could result in significant payments, accruals or material deviation from its position. The Company is subject to income tax examinations by major taxing authorities since inception. There was no provision for income taxes for the period from December 23, 2020 (inception) to December 31, 2020. Net loss per share Net loss per share is computed by dividing net loss by the weighted average number of shares of common stock outstanding during the period, excluding shares of common stock subject to forfeiture by the Initial Shareholders. Company had no shares outstanding as of December 31, 2020. 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 sheets, primarily due to their short-term nature. The Company did not have any financial instruments as of December 31, 2020. Recently issued accounting standard 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 3. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Basis of presentation The accompanying financial statements are presented in U.S. Dollars and 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 auditor 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 shareholder approval of any golden parachute payments not previously approved.

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 September 30, 2021. Marketable securities held in Trust Account At September 30, 2021, substantially all of the assets held in the Trust Account were invested in short term U.S Treasury obligations, which are carried at amortized cost. During the three months ended September 30, 2021, the Company did not withdraw any interest income from the Trust Account to pay for its franchise and income taxes. Common stock subject to possible redemption The Company accounts for its common stock subject to possible redemption in accordance with the guidance in Accounting Standards Codification (“ASC”) Topic 480 “Distinguishing Liabilities from Equity.” Common stock subject to mandatory redemption is classified as a liability instrument and is measured at fair value. Conditionally redeemable common stock (including common stock that features redemption rights that is either within the control of the holder or subject to redemption upon the occurrence of uncertain events not solely within the Company’s control) is classified as temporary equity. At all other times, common stock is classified as stockholders’ equity. The Company’s common stock features certain redemption rights that are considered to be outside of the Company’s control and subject to occurrence of uncertain future events. Deferred offering costs Deferred offering costs consist of underwriting, legal, accounting and other expenses incurred through the balance sheet date that are directly related to the IPO and that are charged to shareholders equity upon the completion of the IPO. Offering costs amounting to $1,548,743 (including $1,000,000 of underwriting fees) were charged to shareholders’ equity upon the completion of the IPO. In addition, underwriters received 57,500 Units (“Underwriter Units”), with such Units restricted from sale until the closing of the Business Combination and with no redemption rights from the Trust Account. Each Underwriter Unit consists of one share of Class A common stock of the Company, par value $0.0001 per share and one Warrant Liabilities The Company accounts for the 5,750,000 Public Warrants, 257,500 Private Unit Warrants, 1,300,000 OTM Warrants and 28,750 Underwriter Warrants issued in connection with the IPO and the Private Placements in accordance with the guidance contained in ASC 815-40 “Contracts in Entity’s Own Equity”. Such guidance provides that because the warrants do not meet the criteria for equity treatment thereunder, each warrant must be recorded as a non-cash liability. Accordingly, the Company classifies each warrant as a liability at its fair value. This liability is subject to re-measurement at each balance sheet date. With each such re-measurement, 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 utilizes a Monte-Carlo simulation model to value the warrants at each reporting period. The Company recorded $15,025,604 of warrant liabilities 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. 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 as of September 30, 2021 and no amounts accrued for interest and penalties. The Company is currently not aware of any issues under review that could result in significant payments, accruals or material deviation from its position. The Company is subject to income tax examinations by major taxing authorities since inception. There was no provision for income taxes for the nine months ended September 30, 2021. Net loss per share Net loss per share is computed by dividing net loss by the weighted average number of shares of common stock outstanding during the period. In the periods when net losses are incurred, no impact of dilutive securities is included in the calculation of diluted weighted average number of common shares outstanding. ​ Reconciliation of Net Loss per Common Share The weighted average shares outstanding are adjusted for the common shares subject to possible redemption. Basic and diluted loss per common share is calculated as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Three Months Ended ​ Nine Months Ended ​ ​ September 30, ​ September 30, ​ 2021 2021 Net loss ​ $ (8,960,156) ​ $ (10,565,658) Weighted average shares outstanding, basic and diluted ​ 3,447,500 ​ 3,899,158 Basic and diluted net loss per common share ​ $ (0.47) ​ $ (0.41) ​ Fair value of financial instruments The fair value of the Company’s assets and liabilities, other than the warrant liabilities described above, which qualify as financial instruments under ASC Topic 820, “Fair Value Measurement and Disclosures,” approximates the carrying amounts represented in the accompanying balance sheet, primarily due to their short-term nature. The Company reported warrants issued at the consummation of its IPO as financial instruments recorded as liabilities at their respective fair values. Recently issued accounting standard 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.

Aldel Financial Inc.
RELATED PARTY TRANSACTIONS	NOTE 5. RELATED PARTY TRANSACTIONS Founder Shares On January 11, 2021, the Company issued an aggregate of 5,750,000 shares of common stock (the “Founder Shares”) to the Sponsor and FGSP for an aggregate purchase price of $25,000 in cash. Sponsor was issued 4,675,000 and FGSP, an affiliate of certain of the Company’s directors, was issued 1,075,000 shares of common stock. On January 15, 2021, the Sponsor transferred an aggregate of 175,000 Founder Shares to members of the Company’s management and board of directors as well as senior advisors, resulting in the Sponsor holding 4,500,000 Founder Shares. On March 25, 2021, the Sponsor and FGSP forfeited to the Company for no consideration, 2,300,000 and 575,000 Founder Shares, respectively, resulting in a decrease in the aggregate number of Founder Shares outstanding from 5,750,000 Founder Shares to 2,875,000, and resulting in Sponsor and FGSP holding 2,200,000 and 500,000 Founder Shares, respectively. The Founder Shares include an aggregate of up to 375,000 shares subject to forfeiture by the Sponsor and FGSP to the extent that the underwriters’ over-allotment is not exercised in full or in part, so that the Initial Shareholders will collectively own 20% of the Company’s issued and outstanding shares after the Proposed Offering (assuming the Initial Shareholders do not purchase any Public Shares in the Proposed Offering and excluding the securities underlying the $15 Private Warrants, the Private Units and the Units issued to underwriters). The Initial Shareholders have agreed not to transfer, assign or sell any of the Founder Shares (except to certain permitted transferees) until, with respect to 50% of the Founder Shares, the earlier of (i) twelve months after the date of the consummation of a Business Combination, or (ii) the date on which the closing price of the Company’s Class A common stock equals or exceeds $12.00 per share (as adjusted for stock splits, stock dividends, reorganizations and recapitalizations) for any 20 trading days within any 30 -trading day period commencing after a Business Combination, with respect to the remaining 50% of the Founder Shares, 12 months after the date of the consummation of a Business Combination, or earlier, in each case, if, subsequent to a Business Combination, the Company consummates a subsequent liquidation, merger, stock exchange or other similar transaction which results in all of the Company’s shareholders having the right to exchange their Public Shares for cash, securities or other property. Promissory Notes On January 11, 2021, the Company issued unsecured Promissory Notes to the Sponsor and FGSS, an affiliate of certain of the Company’s directors, pursuant to which the Company borrowed principal amounts of $225,000 and $25,000, respectively. As of December 31, 2020, there was no balance outstanding under the Promissory Notes. The Promissory Notes are noninterest bearing and payable on the earlier of (i) the consummation of the Proposed Offering or (ii) the date on which the Company determines not to conduct the Proposed Offering. Administrative Services Agreement The Company agreed to enter into an administrative services agreement (the “Administrative Services Agreement”) with the Sponsor whereby the Sponsor will perform certain services for the Company for a monthly fee of $10,000.	NOTE 6.

Basis of presentation		Basis of Presentation —
Use of estimates		Use of Estimates The most significant estimate that is susceptible to notable changes in the near-term relates to the provision for unpaid losses and loss adjustment expenses (including those losses incurred but not reported (IBNR)). Although some variability is inherent in this estimate, the Company believes that the current estimate is reasonable in all material respects. This estimate is reviewed regularly and adjusted as necessary. Adjustments related to changes in estimates are reflected in the Company’s results of operations in the period in which those estimates changed.	Use of Estimates — The most significant estimate that is susceptible to notable change in the near-term relates to the provision for unpaid losses and loss adjustment expenses (including those losses incurred but not reported (IBNR)). Although some variability is inherent in this estimate, the Company believes that the current estimate is reasonable in all material respects. This estimate is reviewed regularly and adjusted as necessary. Adjustments related to changes in estimates are reflected in the Company’s results of operations in the period in which those estimates changed.
Income taxes			Income Taxes — Where applicable, income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax-credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. Deferred tax assets are recognized to the extent that there is sufficient positive evidence as allowed under the ASC Topic 740, “Income Taxes” (“Topic 740”), to support the recoverability of those deferred tax assets. The Company establishes a valuation allowance to the extent that there is insufficient evidence to support the recoverability of the deferred tax asset under Topic 740. In making such a determination, management considers all available positive and negative evidence, including future reversals of existing taxable temporary differences, projected future taxable income, tax-planning strategies, and results of recent operations. If it is determined that the deferred tax assets would be realizable in the future in excess of their net recorded amount, an adjustment would be made to the deferred tax asset valuation allowance, which would reduce the provision for income taxes. As of December 31, 2020 and 2019, the Company did not have any unrecognized tax benefits and had no accrued interest or penalties related to uncertain tax positions. If recorded, interest and penalties would be recorded as interest expense or penalty expense in the consolidated statements of income and other comprehensive income.

Emerging growth company	Emerging growth company The Company is an “emerging growth company,” as defined in Section 2(a) of the Securities Act, as modified by the Jumpstart Our Business Startups Act of 2012 (the “JOBS Act”), and it may take advantage of certain exemptions from various reporting requirements that are applicable to other public companies that are not emerging growth companies including, but not limited to, not being required to comply with the auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act, 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 shareholder 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	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 revenues and expenses during the reporting periods. 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 September 30, 2021.
Marketable Securities Held in Trust Account		Marketable securities held in Trust Account At September 30, 2021, substantially all of the assets held in the Trust Account were invested in short term U.S Treasury obligations, which are carried at amortized cost. During the three months ended September 30, 2021, the Company did not withdraw any interest income from the Trust Account to pay for its franchise and income taxes.
Common stock subject to possible redemption		Common stock subject to possible redemption The Company accounts for its common stock subject to possible redemption in accordance with the guidance in Accounting Standards Codification (“ASC”) Topic 480 “Distinguishing Liabilities from Equity.” Common stock subject to mandatory redemption is classified as a liability instrument and is measured at fair value. Conditionally redeemable common stock (including common stock that features redemption rights that is either within the control of the holder or subject to redemption upon the occurrence of uncertain events not solely within the Company’s control) is classified as temporary equity. At all other times, common stock is classified as stockholders’ equity. The Company’s common stock features certain redemption rights that are considered to be outside of the Company’s control and subject to occurrence of uncertain future events.
Deferred offering costs	Deferred offering costs Deferred offering costs consist of underwriting and legal expenses incurred through the balance sheet date that are directly related to the Proposed Offering and that will be charged to shareholders equity upon the completion of the Proposed Offering. Should the Proposed Offering prove to be unsuccessful, these deferred costs, as well as additional expenses incurred, will be charged to operations.	Deferred offering costs Deferred offering costs consist of underwriting, legal, accounting and other expenses incurred through the balance sheet date that are directly related to the IPO and that are charged to shareholders equity upon the completion of the IPO. Offering costs amounting to $1,548,743 (including $1,000,000 of underwriting fees) were charged to shareholders’ equity upon the completion of the IPO. In addition, underwriters received 57,500 Units (“Underwriter Units”), with such Units restricted from sale until the closing of the Business Combination and with no redemption rights from the Trust Account. Each Underwriter Unit consists of one share of Class A common stock of the Company, par value $0.0001 per share and one
Warrant Liabilities		Warrant Liabilities The Company accounts for the 5,750,000 Public Warrants, 257,500 Private Unit Warrants, 1,300,000 OTM Warrants and 28,750 Underwriter Warrants issued in connection with the IPO and the Private Placements in accordance with the guidance contained in ASC 815-40 “Contracts in Entity’s Own Equity”. Such guidance provides that because the warrants do not meet the criteria for equity treatment thereunder, each warrant must be recorded as a non-cash liability. Accordingly, the Company classifies each warrant as a liability at its fair value. This liability is subject to re-measurement at each balance sheet date. With each such re-measurement, 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 utilizes a Monte-Carlo simulation model to value the warrants at each reporting period. The Company recorded $15,025,604 of warrant liabilities as of September 30, 2021.
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 as of December 31, 2020 and no amounts accrued for interest and penalties. The Company is currently not aware of any issues under review that could result in significant payments, accruals or material deviation from its position. The Company is subject to income tax examinations by major taxing authorities since inception. There was no provision for income taxes for the period from December 23, 2020 (inception) to December 31, 2020.

DESCRIPTION OF ORGANIZATION A_3

DESCRIPTION OF ORGANIZATION AND BUSINESS OPERATIONS	Dec. 31, 2020	Sep. 30, 2021
Aldel Financial Inc.
DESCRIPTION OF ORGANIZATION AND BUSINESS OPERATIONS	NOTE 1. DESCRIPTION OF ORGANIZATION AND BUSINESS OPERATIONS Aldel Financial Inc. (the “Company”) is a blank check company incorporated in Delaware on December 23, 2020. The Company was formed for the purpose of merger, share exchange, asset acquisition, stock purchase, recapitalization, reorganization or other similar business combination with one or more businesses or entities (“Business Combination”). Although the Company is not limited to a particular industry or geographic region for purposes of consummating a Business Combination, the Company intends to focus its search for a target business that is exiting the restructuring process or that has transient current ownership. Aldel Financial Inc. will target companies with established operating models that have strong management teams, realigned capital structures, positive cash flows prospects, and a clear and well-defined pathway for growing profitably over the long-term. 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 through December 31, 2020 relates to the Company’s formation and the proposed initial public offering (“Proposed Offering”), which is described below. The Company will not generate any operating revenues until after the completion of its initial Business Combination, at the earliest. The Company will generate nonoperating income in the form of interest income from the proceeds derived from 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 i) the Proposed Offering of 10,000,000 units at $10.00 per unit (or 11,500,000 units if the underwriters’ 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, ii) the sale of 1,300,000 $15.00 exercise price warrants (the “$15 Private Warrants”) at a price of $0.10 per $15 Private Warrant, and iii) the sale of 500,000 units (or 515,000 private units if the over-allotment option is exercised in full) at $10.00 per unit (the “Private Units”) in a private placement. The Company will sell 650,000 of the $15 Private Warrants and all of the 500,000 Private Units (or 515,000 Private units if the over-allotment option is exercised in full) to the Company’s sponsor, Aldel Investors LLC (the “Sponsor”), and remaining 650,000 $15 Private Warrants to FG SPAC Partners LP (“FGSP”), an affiliate of certain of the Company’s directors, in a private placement that will close simultaneously with the Proposed Offering. Each Private Unit will consist of one Class A common share and one-half of one non-redeemable warrant (“Private Unit Warrant”). Each whole Private Unit Warrant will entitle the holder to purchase one share of common stock at an exercise price of $11.50 per share. The Company intends to list the Units on the New York Stock Exchange (“NYSE”). The Company’s management has broad discretion with respect to the specific application of the net proceeds of the Proposed Offering and sale of the $15 Private Warrants and Private Units, although substantially all of the net proceeds are intended to be applied generally toward consummating a Business Combination. NYSE 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 net assets held in the Trust Account (as defined below) (net of amounts disbursed to management for working capital purposes). 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 $10.10 per Unit sold in the Proposed Offering will be held in a trust account (“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 shareholders, as described below. The Company will provide its shareholders 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 shareholder 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 shareholder approval of a Business Combination at a meeting called for such purpose at which shareholders may seek to redeem their shares, regardless of whether they vote for or against the proposed Business Combination. The Company will proceed with a Business Combination only if the Company has net tangible assets of at least $5,000,001 upon or immediately prior to such consummation of a Business Combination and, if the Company seeks shareholder approval, a majority of the outstanding shares voted are voted in favor of the Business Combination. If the Company seeks shareholder 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 will provide that a public shareholder, together with any affiliate of such shareholder or any other person with whom such shareholder 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 holders of Public Shares will be entitled to redeem their Public Shares for a pro rata portion of the amount then in the Trust Account (including 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). There will be no redemption rights upon the completion of a Business Combination with respect to the Company’s warrants. A portion of the Public Shares will be recorded at a redemption value and classified as temporary equity upon the completion of the Proposed Offering, in accordance with Accounting Standard Codification (“ASC”) Topic 480 “Distinguishing Liabilities from Equity” in order for the Company to maintain net tangible assets of at least $5,000,001. If a shareholder vote is not required and the Company does not decide to hold a shareholder 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 (“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 Sponsor, FGSP, officers, directors and advisors (the “Initial Shareholders”) have agreed (a) to vote their Founder Shares (as defined in Note 5) as well as any common shares underlying the Private Units, 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 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 shareholders with the opportunity to redeem their Public Shares in conjunction with any such amendment; (c) not to redeem any shares (including the Founder Shares as well as any common shares underlying the Private Units) into the right to receive cash from the Trust Account in connection with a shareholder 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 shareholder approval in connection therewith) or a vote to amend the provisions of the amended and restated certificate of incorporation relating to shareholders’ rights of pre-Business Combination activity and (d) that the Founder Shares, the Private Units and $15 Private Warrants (including underlying securities) shall not participate in any liquidating distributions upon winding up if a Business Combination is not consummated. However, the Initial Shareholders 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. The Company will have until 18 months from the closing of the Proposed Offering to consummate a Business Combination (as such period may be extended pursuant to the amended and restated certificate of incorporation, the “Combination Period”). If the Company is unable to complete a Business Combination within the Combination Period, the Company will (i) cease all operations except for the purpose of winding up, (ii) as promptly as reasonably possible but 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 vendor for services rendered or products sold to the Company, or a prospective target business with which the Company has discussed entering into a transaction agreement, reduce the amounts in the Trust Account to below $10.10 per share, except as to any claims by a third party who executed a waiver of any and all rights to seek access to the Trust Account and except as to any claims under the Company’s indemnity of the underwriters of the Proposed Offering against certain liabilities, including liabilities under the Securities Act of 1933, as amended (the “Securities Act”). In the event that an executed waiver is deemed to be unenforceable against a third party, the Sponsor will not be responsible to the extent of any liability for such third-party claims. 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 no cash and working capital deficit of $56,470. The Company has incurred and expects to continue to incur significant costs in pursuit of its Proposed Offering and Business Combination plans. These conditions raise substantial doubt about the Company’s ability to continue as a going concern within one year after the date that the financial statements are issued. Management plans to address this uncertainty through a Proposed Offering as discussed in Note 3, as well as sale of $15 Private Warrants and Private Units as discussed above. 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. Subsequent to December 31, 2020, the Sponsor has agreed to loan the Company an aggregate amount of $225,000 and FG SPAC Solutions LLC (“FGSS”), an affiliate of certain of the Company’s directors, has agreed to loan the Company an aggregate amount of $25,000 to be used, in part, for transaction costs incurred in connection with the Proposed Offering (the “Promissory Notes”). As of December 31, 2020, there was not any balance outstanding under the Promissory Notes (see Note 5). 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 Aldel Financial Inc. (the “Company” or “Aldel”) is a blank check company incorporated in Delaware on December 23, 2020. The Company was formed for the purpose of merger, share exchange, asset acquisition, stock purchase, recapitalization, reorganization or other similar business combination with one or more businesses or entities (“Business Combination”). Although the Company is not limited to a particular industry or geographic region for purposes of consummating a Business Combination, the Company intends to focus its search for a target business on companies that are exiting the restructuring process or that have transient current ownership. Aldel Financial Inc. will target companies with established operating models that have strong management teams, realigned capital structures, positive cash flows prospects, and a clear and well-defined pathway for growing profitably over the long-term. 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 September 30, 2021, the Company had not yet commenced any operations. All activity through September 30, 2021 relates to the Company’s formation and the initial public offering (“IPO”), which is described below. The Company will not generate any operating revenues until after the completion of its initial Business Combination, at the earliest. The Company will generate nonoperating income in the form of interest income from the proceeds derived from the IPO. The Company has selected December 31 as its fiscal year end. Aldel Merger Sub LLC is a wholly- owned subsidiary of the Company and currently has no operations. The registration statement for the Company’s IPO was declared effective on April 8, 2021. On April 12, 2021, the Company consummated its IPO of 11,500,000 units (the “Units”), including 1,500,000 Units that were issued pursuant to the underwriters’ full exercise of their over-allotment option. Each Unit consists of one share of Class A common stock of the Company, par value $0.0001 per share (the “Public Share”) and one-half of one redeemable warrant (“Public Warrant”), each whole Public Warrant entitling the holder thereof to purchase one share of common stock for $11.50 per share. The Units were sold at a price of $10.00 per Unit, generating gross proceeds to the Company of $115,000,000. The Public Warrants will become exercisable on the later of 30 days after the completion of Business Combination and 12 months from the closing of the IPO, and will expire five years after the completion of Business Combination or earlier upon Company’s liquidation. Simultaneously with the closing of the IPO, the Company consummated private placements (the “Private Placements”) in which (i) Aldel Investors LLC (the “Sponsor”) purchased 515,000 private units (the “Private Units”) at a price of $10.00 per Private Unit, generating total proceeds of $5,150,000, and (ii) the Sponsor and FG SPAC Partners LP (“FGSP”) purchased an aggregate of 1,300,000 warrants (“OTM Warrants” and, together with the Private Units, the “Private Placement Securities”) at a price of $0.10 per warrant, each exercisable to purchase one share of Class A common stock at $15.00 per share, for an aggregate purchase price of $130,000. Each Private Unit consists of one Common Stock and one-half of one non-redeemable warrant (“Private Unit Warrant”). Each whole Private Unit Warrant will entitle the holder to purchase one share of Common Stock at an exercise price of $11.50 per share. The Private Unit Warrants have terms similar to the Public Warrants, except that the Private Unit Warrants will be non-redeemable and may be exercised on a cashless basis so long as they continue to be held by the initial shareholders or their permitted transferees. Additionally, Private Unit Warrants and the shares issuable upon the exercise of the Private Unit Warrants will not be transferable, assignable or salable until after the completion of a Business Combination. The OTM Warrants will entitle the holder to purchase one share of Common Stock at an exercise price of $15.00 per each share, will be exercisable for a period of 10 years from the date of Business Combination, will be non-redeemable, and may be exercised on a cashless basis so long as they continue to be held by the initial shareholders or their permitted transferees. Additionally, OTM Warrants and the shares issuable upon the exercise of the OTM Warrants will not be transferable, assignable or salable until after the completion of a Business Combination. The Company’s Units are listed on the New York Stock Exchange (“NYSE”). The Company’s management has broad discretion with respect to the specific application of the net proceeds of the IPO and sale of the Private Placement Securities, although substantially all of the net proceeds are intended to be applied generally toward consummating a Business Combination. NYSE 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 net assets held in the Trust Account (as defined below). 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. Following the closing of the IPO on April 12, 2021, an amount of $116,150,000 ($10.10 per Unit) from the net proceeds of the sale of Units in the IPO and the sale of Private Placement Securities were placed in a trust account (“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 shareholders, as described below. The Company will provide its shareholders 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 shareholder meeting called to approve the Business Combination or (ii) by means of a tender offer.

If the Company seeks shareholder 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 will provide that a public shareholder, together with any affiliate of such shareholder or any other person with whom such shareholder 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 holders of Public Shares will be entitled to redeem their Public Shares for a pro rata portion of the amount then in the Trust Account (including 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). There will be no redemption rights upon the completion of a Business Combination with respect to the Company’s warrants. If a shareholder vote is not required and the Company does not decide to hold a shareholder 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 (“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 Sponsor, FGSP, officers, directors and advisors (the “Initial Shareholders”) have agreed (a) to vote their Founder Shares (as defined in Note 6) as well as any common shares underlying the Private Units, and any Public Shares purchased during or after the IPO 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 shareholders with the opportunity to redeem their Public Shares in conjunction with any such amendment; (c) not to redeem any shares (including the Founder Shares as well as any common shares underlying the Private Units) into the right to receive cash from the Trust Account in connection with a shareholder 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 shareholder approval in connection therewith) or a vote to amend the provisions of the amended and restated certificate of incorporation relating to shareholders’ rights of pre-Business Combination activity and (d) that the Founder Shares, the Private Units and OTM Warrants (including underlying securities) shall not participate in any liquidating distributions upon winding up if a Business Combination is not consummated. However, the Initial Shareholders will be entitled to liquidating distributions from the Trust Account with respect to any Public Shares purchased during or after the IPO if the Company fails to complete its Business Combination. The Company will have until 18 months from the closing of the IPO to consummate a Business Combination (as such period may be extended pursuant to the amended and restated certificate of incorporation, the “Combination Period”). If the Company is unable to complete a Business Combination within the Combination Period, the Company will (i) cease all operations except for the purpose of winding up, (ii) as promptly as reasonably possible but 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 vendor for services rendered or products sold to the Company, or a prospective target business with which the Company has discussed entering into a transaction agreement, reduce the amounts in the Trust Account to below $10.10 per share, except as to any claims by a third party who executed a waiver of any and all rights to seek access to the Trust Account and except as to any claims under the Company’s indemnity of the underwriters of the Offering against certain liabilities, including liabilities under the Securities Act of 1933, as amended (the “Securities Act”). In the event that an executed waiver is deemed to be unenforceable against a third party, the Sponsor will not be responsible to the extent of any liability for such third-party claims. 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 considerations As of September 30, 2021, the Company has approximately $407,664 in its bank account and working capital surplus of approximately $1.1 million. Company does not believe it will need to raise additional funds in order to meet the expenditures required for operating the business. However, if the estimate of the costs of identifying a target business, undertaking in-depth due diligence and negotiating a Business Combination are less than the actual amount necessary to do so, Company may have insufficient funds available to operate the business prior to the initial Business Combination. In order to finance transaction costs in connection with a Business Combination, the Sponsor or an affiliate of the Sponsor, or certain of our officers and directors may, but are not obligated to, loan the funds to the Company as may be required.

REVISION OF PREVIOUSLY ISSUED FINANCIAL STATEMENTS	NOTE 2. REVISION OF PREVIOUSLY ISSUED FINANCIAL STATEMENTS In connection with the preparation of the Company’s financial statements as of September 30, 2021, management determined it should revise its previously reported financial statements. The Company determined, at the closing of the Company’s Initial Public Offering and shares sold pursuant to the exercise of the underwriters’ overallotment, it had improperly valued its Class A common shares subject to possible redemption. The Company previously determined the Class A common shares subject to possible redemption to be equal to the redemption value of $10.10 per Class A common share while also taking into consideration a redemption cannot result in net tangible assets and total There has been no change in the Company’s total assets, liabilities, or operating results.

SUMMARY OF SIGNIFICANT ACCOUN_8

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	Dec. 31, 2020	Sep. 30, 2021
Aldel Financial Inc.
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	NOTE 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Basis of presentation The accompanying financial statements are presented in U.S. Dollars and 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 auditor 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 shareholder 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 revenues and expenses during the reporting periods. 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 or cash equivalents as of December 31, 2020. Deferred offering costs Deferred offering costs consist of underwriting and legal expenses incurred through the balance sheet date that are directly related to the Proposed Offering and that will be charged to shareholders equity upon the completion of the Proposed Offering. Should the Proposed Offering prove to be unsuccessful, these deferred costs, as well as additional expenses incurred, will be charged to operations. 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 as of December 31, 2020 and no amounts accrued for interest and penalties. The Company is currently not aware of any issues under review that could result in significant payments, accruals or material deviation from its position. The Company is subject to income tax examinations by major taxing authorities since inception. There was no provision for income taxes for the period from December 23, 2020 (inception) to December 31, 2020. Net loss per share Net loss per share is computed by dividing net loss by the weighted average number of shares of common stock outstanding during the period, excluding shares of common stock subject to forfeiture by the Initial Shareholders. Company had no shares outstanding as of December 31, 2020. 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 sheets, primarily due to their short-term nature. The Company did not have any financial instruments as of December 31, 2020. Recently issued accounting standard 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 3. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Basis of presentation The accompanying financial statements are presented in U.S. Dollars and 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 auditor 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 shareholder approval of any golden parachute payments not previously approved.

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.

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 September 30, 2021. Marketable securities held in Trust Account At September 30, 2021, substantially all of the assets held in the Trust Account were invested in short term U.S Treasury obligations, which are carried at amortized cost. During the three months ended September 30, 2021, the Company did not withdraw any interest income from the Trust Account to pay for its franchise and income taxes. Common stock subject to possible redemption The Company accounts for its common stock subject to possible redemption in accordance with the guidance in Accounting Standards Codification (“ASC”) Topic 480 “Distinguishing Liabilities from Equity.” Common stock subject to mandatory redemption is classified as a liability instrument and is measured at fair value. Conditionally redeemable common stock (including common stock that features redemption rights that is either within the control of the holder or subject to redemption upon the occurrence of uncertain events not solely within the Company’s control) is classified as temporary equity. At all other times, common stock is classified as stockholders’ equity. The Company’s common stock features certain redemption rights that are considered to be outside of the Company’s control and subject to occurrence of uncertain future events. Deferred offering costs Deferred offering costs consist of underwriting, legal, accounting and other expenses incurred through the balance sheet date that are directly related to the IPO and that are charged to shareholders equity upon the completion of the IPO. Offering costs amounting to $1,548,743 (including $1,000,000 of underwriting fees) were charged to shareholders’ equity upon the completion of the IPO. In addition, underwriters received 57,500 Units (“Underwriter Units”), with such Units restricted from sale until the closing of the Business Combination and with no redemption rights from the Trust Account. Each Underwriter Unit consists of one share of Class A common stock of the Company, par value $0.0001 per share and one Warrant Liabilities The Company accounts for the 5,750,000 Public Warrants, 257,500 Private Unit Warrants, 1,300,000 OTM Warrants and 28,750 Underwriter Warrants issued in connection with the IPO and the Private Placements in accordance with the guidance contained in ASC 815-40 “Contracts in Entity’s Own Equity”. Such guidance provides that because the warrants do not meet the criteria for equity treatment thereunder, each warrant must be recorded as a non-cash liability. Accordingly, the Company classifies each warrant as a liability at its fair value. This liability is subject to re-measurement at each balance sheet date. With each such re-measurement, 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 utilizes a Monte-Carlo simulation model to value the warrants at each reporting period. The Company recorded $15,025,604 of warrant liabilities 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. 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 as of September 30, 2021 and no amounts accrued for interest and penalties. The Company is currently not aware of any issues under review that could result in significant payments, accruals or material deviation from its position. The Company is subject to income tax examinations by major taxing authorities since inception. There was no provision for income taxes for the nine months ended September 30, 2021. Net loss per share Net loss per share is computed by dividing net loss by the weighted average number of shares of common stock outstanding during the period. In the periods when net losses are incurred, no impact of dilutive securities is included in the calculation of diluted weighted average number of common shares outstanding. ​ Reconciliation of Net Loss per Common Share The weighted average shares outstanding are adjusted for the common shares subject to possible redemption. Basic and diluted loss per common share is calculated as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Three Months Ended ​ Nine Months Ended ​ ​ September 30, ​ September 30, ​ 2021 2021 Net loss ​ $ (8,960,156) ​ $ (10,565,658) Weighted average shares outstanding, basic and diluted ​ 3,447,500 ​ 3,899,158 Basic and diluted net loss per common share ​ $ (0.47) ​ $ (0.41) ​ Fair value of financial instruments The fair value of the Company’s assets and liabilities, other than the warrant liabilities described above, which qualify as financial instruments under ASC Topic 820, “Fair Value Measurement and Disclosures,” approximates the carrying amounts represented in the accompanying balance sheet, primarily due to their short-term nature. The Company reported warrants issued at the consummation of its IPO as financial instruments recorded as liabilities at their respective fair values. Recently issued accounting standard 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.

FAIR VALUE OF FINANCIAL INSTR_2

FAIR VALUE OF FINANCIAL INSTRUMENTS	9 Months Ended
	Sep. 30, 2021
Aldel Financial Inc.
FAIR VALUE OF FINANCIAL INSTRUMENTS	NOTE 9. FAIR VALUE OF FINANCIAL INSTRUMENTS The fair value of the Company’s financial assets and liabilities reflects management’s estimate of amounts that the Company would have received in connection with the sale of the assets or paid in connection with the transfer of the liabilities in an orderly transaction between market participants at the measurement date. In connection with measuring the fair value of its assets and liabilities, the Company seeks to maximize the use of observable inputs (market data obtained from independent sources) and to minimize the use of unobservable inputs (internal assumptions about how market participants would price assets and liabilities). The following fair value hierarchy is used to classify assets and liabilities based on the observable inputs and unobservable inputs used in order to value the assets and liabilities. Level 1: Quoted prices in active markets for identical assets or liabilities. An active market for an asset or liability is a market in which transactions for the asset or liability occur with sufficient frequency and volume to provide pricing information on an ongoing basis. Level 2: Observable inputs other than Level 1 inputs. Examples of Level 2 inputs include quoted prices in active markets for similar assets or liabilities and quoted prices for identical assets or liabilities in markets that are not active. Level 3: Unobservable inputs based on our assessment of the assumptions that market participants would use in pricing the asset or liability. The fair value of Public Warrants is determined using the level 1 input. The estimated fair value of the Private Unit Warrants, OTM Warrants and Underwriter Warrants are determined using level 3 inputs in a Monte-Carlo simulation model. Inherent in a Monte-Carlo simulation model are assumptions related to expected stock-price volatility (pre-merger and post-merger), expected term, dividend yield and risk-free interest rate. The Company estimates the volatility of its common stock based on factors including but not limited to the historical performance of the Russell 2000 and managements understanding of the volatility associated with instruments of other similar entities. The risk-free interest rate is based on the U.S. Treasury Constant Maturity similar to the expected remaining life of the warrants. The expected life of the warrants is assumed to be equivalent to their remaining contractual term. The dividend rate is based on the historical rate, which the Company anticipates to remain at zero. The following table presents information about the Company’s assets and liabilities that are measured at fair value on a recurring basis at September 30, 2021, and indicates the fair value hierarchy of the valuation inputs the Company utilized to determine such fair value: ​ ​ ​ ​ ​ ​ Description Level Fair Value Liabilities: ​ Public Warrants 1 ​ $ 11,615,000 Private Unit Warrants 3 ​ $ 460,221 OTM Warrants 3 ​ $ 2,898,999 Underwriter Warrants 3 ​ $ 51,384 Total warrant liabilities ​ ​ ​ $ 15,025,604 ​ Following are the significant inputs in the valuation model as of September 30, 2021: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Private Unit ​ ​ ​ ​ Underwriter Inputs Warrant OTM Warrant Warrant Exercise price ​ $ 11.50 ​ $ 15.00 ​ $ 11.50 Common stock price $ 10.09 $ 10.09 $ 10.09 Volatility ​ 5% pre-merger / ​ 5% pre-merger / ​ 5% pre-merger / Probability of completing a Business Combination ​ 90% ​ ​ 90% ​ ​ 90% Expected term of the warrants ​ 5.53 ​ ​ 10.54 ​ ​ 5.53 Risk-free rate ​ 0.05% pre-merger / ​ ​ 0.05% pre-merger / ​ ​ 0.05% pre-merger / Dividend yield ​ 0 ​ ​ 0 ​ ​ 0 Discount for lack of marketability ​ 15% ​ ​ 15% ​ ​ 15% ​ The change in fair value of the warrant liabilities is summarized as follows: ​ ​ ​ ​ ​ Warrant liabilities as of December 31, 2020 $ — Warrant liability recorded at fair value at issuance of warrants at close of IPO, private placement, and Underwriters’ over-allotment option as of April 12, 2021 ​ 5,917,625 Change in fair value of warrant liabilities ​ 9,107,979 Total warrant liabilities as of September 30,2021(1) ​ $ 15,025,604 (1)

BUSINESS COMBINATION AGREEMENT

BUSINESS COMBINATION AGREEMENT	9 Months Ended
	Sep. 30, 2021
Aldel Financial Inc.
BUSINESS COMBINATION AGREEMENT	NOTE 10. BUSINESS COMBINATION AGREEMENT On August 17, 2021, Aldel entered into a Business Combination agreement (the “Business Combination Agreement”) by and among Aldel Financial Inc., Aldel Merger Sub LLC, a Delaware limited liability company and a wholly-owned Subsidiary of the Company (“Merger Sub”) and The Hagerty Group, LLC, a Delaware limited liability company (“Hagerty”). Pursuant to the Business Combination Agreement (a) Merger Sub will be merged with and into Hagerty (the “Merger”), whereupon the separate limited liability company existence of Merger Sub shall cease and Hagerty shall be the surviving company (Hagerty following the Merger is sometimes hereinafter referred to as the “OpCo”) and continue its existence under the Delaware Limited Liability Company Act (the “LLC Act”); (b) the existing limited liability company agreement of Hagerty will be amended and restated, to, among other things, make Aldel a member of the OpCo; and (c) Company will change its name to Hagerty, Inc. (“New Hagerty”). As a result of the Business Combination, New Hagerty will be the publicly traded reporting company in an “Up-C” structure. Under the Business Combination Agreement, Aldel has agreed to acquire all of the limited liability equity interests (the “Company Equity Interests”) of Hagerty for $3.0 billion in aggregate consideration (less the Company Transaction Expenses Differential (as defined in the Business Combination Agreement) or plus the Buyer Excess (as defined in the Business Combination Agreement), as applicable) (the “Equity Value”), comprising the Mixed Consideration and the Equity Consideration (as defined below) (together, the “Merger Consideration”). “Mixed Consideration” means (a) the Secondary Consideration (as defined below) plus (b) a number of units of equity interests in OpCo (“Units”) and shares of Class V voting non-economic common stock (“Class V Common Stock”) in New Hagerty, in each case equal to (i) the quotient obtained by dividing (a) the Equity Value by (b) $10.00 (the “Exchange Ratio”) multiplied by (ii) (A) the number of Company Equity Interests owned by Hagerty Holding Corp. (“HHC”) as of the closing divided by (B) the total number of issued and outstanding Company Equity Interests as of the closing minus (iii) the quotient of the Secondary Cash Consideration divided by $10.00. “Secondary Consideration” means $450,000,000 plus the amount by which the sum of the amount in the Trust Account (after giving effect to redemptions by existing stockholders of the Buyer), plus the aggregate amount of the PIPE Financing (as defined below) exceeds $750,000,000; provided that such additional sum shall not exceed $50,000,000. “Equity Consideration” means a number of Units and shares of Class V Common Stock, in each case equal to (a) the Exchange Ratio multiplied by (b) (i) the number of Company Equity Interests owned by Markel Corporation (“Markel”) as of the closing divided by (ii) the total number of issued and outstanding Company Equity Interests as of the closing. At the effective time of the Merger (the “Effective Time”), by virtue of the Merger and without any further action on the part of Aldel, Merger Sub or Hagerty, each Company Equity Interest issued and outstanding immediately prior to the Effective Time shall be canceled and automatically converted into the right to receive: (i) in the case of Markel, the Equity Consideration; and (ii) in the case of HHC, the Mixed Consideration. As of the Effective Time, all Company Equity Interests shall thereafter cease to have any rights with respect thereto, except the right to receive the foregoing consideration. The units of equity interests of Merger Sub (the “Newco Units”) that are issued and outstanding immediately prior to the Effective Time will, by virtue of the Merger and without further action on the part of Aldel, be converted into an aggregate number of Units equal to the number of Aldel’s Class A common stock and Founder Shares issued and outstanding immediately prior to the Effective Time. Each Founder Share that is issued and outstanding immediately prior to the Effective Time shall be automatically converted into one share of Aldel’s Class A common stock. No certificates or scrip representing fractional shares of Aldel’s common stock will be issued pursuant to the Merger. Aldel, Merger Sub and Hagerty have made customary representations, warranties and covenants in the Business Combination Agreement, including, among other things, covenants with respect to the conduct of Aldel and Hagerty prior to the closing of the Business Combination. The parties have also agreed to customary “no shop” obligations. The representations and warranties of Aldel, Merger Sub and Hagerty will not survive the closing of the Merger. The closing of the Business Combination is subject to certain customary conditions of the respective parties, including, among other things, that: (i) the applicable Aldel stockholder and Hagerty member approvals shall have been obtained; (ii) there shall have been no Company Material Adverse Effect or Buyer Material Adverse Effect (each as defined in the Business Combination Agreement) since the date of the Business Combination Agreement; (iii) the waiting period (or any extension thereof) applicable under the Hart-Scott-Rodino Antitrust Improvements Act of 1976 shall have expired or terminated; (iv) the Aggregate Cash Proceeds (as defined in the Business Combination Agreement) after deducting certain transaction expenses and the repayment of any unpaid or contingent liabilities of Aldel, including fees associated with Aldel’s initial public offering and operations prior to the date of the Business Combination Agreement, shall not be less than $450 million; (v) Aldel’s initial listing application in connection with the Transactions (as defined in the Business Combination Agreement) shall have been approved by the NYSE so that immediately following the Merger, New Hagerty satisfies any applicable initial and continuing listing requirements of NYSE; and (vi) each of the parties to the Additional Agreements shall have delivered, or caused to be delivered, duly executed copies of the Additional Agreements. “Additional Agreements” means the Sponsor Letter Agreement, the Tax Receivable Agreement, the Amended and Restated Registration Rights Agreement, the LLC Agreement, the Exchange Agreement, the Lock-up Agreement, and the Sponsor Warrant Lock-up Agreement. In connection with the proposed Business Combination, Aldel entered into subscription agreements (the “Subscription Agreements”) with certain “qualified institutional buyers” or “accredited investors” as defined in the applicable SEC regulations (the “PIPE Financing investors”), pursuant to which the PIPE Financing investors have agreed to subscribe for and purchase, and Aldel has agreed to issue and sell to the PIPE Financing investors, an aggregate of 70,385,000 shares of Aldel Class A common stock (the “PIPE Shares”) and an aggregate of 12,669,300 warrants to purchase shares of Aldel Class A common stock (the “PIPE Warrants” and, together with the PIPE Shares, the “PIPE Securities”), for aggregate gross proceeds of $703,850,000 (the “PIPE Financing”). The PIPE Securities to be issued pursuant to the Subscription Agreements have not been registered under the Securities Act in reliance upon the exemption provided by Section 4(a)(2) of the Securities Act and/or Regulation D promulgated thereunder. The purpose of the PIPE Financing is to raise additional capital for use in connection with the Business Combination and to meet the minimum cash requirement provided in the Business Combination Agreement. The closing of the sale of the PIPE Securities (the “PIPE Closing”) will be contingent upon the substantially concurrent consummation of the Business Combination and will occur on the date of, and immediately prior to, the consummation of the Business Combination. The PIPE Closing will be subject to customary conditions. In connection with the Business Combination Agreement, Aldel Investors LLC, Aldel LLC, and the directors and executive officers holding securities of Aldel (each a “Stockholder”) each entered into a support agreement (the “Sponsor Letter Agreement”) with Aldel and Hagerty, pursuant to which each Stockholder agrees to vote the shares of Aldel common stock beneficially owned by them (a) in favor of the approval and adoption of the Business Combination Agreement and the transactions contemplated thereby, (b) in favor of any other matter reasonably necessary to the consummation of the transactions contemplated by the Business Combination Agreement, (c) against the approval of any transaction that would impede or prevent the consummation of the Business Combination, and (d) against any amendment of the certificate of incorporation or bylaws of Aldel or any change in Buyer’s capitalization, corporate structure or business other than as contemplated by the Business Combination Agreement. Each Stockholder further agrees that it will (i) not exercise its right to redeem all or a portion of such Stockholder’s shares of Aldel common stock beneficially owned by them (in connection with the Business Combination or otherwise) and (ii) waive any adjustment to the conversion ratio set forth in Aldel’s organizational documents.

Basis of presentation		Basis of Presentation —
Use of estimates		Use of Estimates The most significant estimate that is susceptible to notable changes in the near-term relates to the provision for unpaid losses and loss adjustment expenses (including those losses incurred but not reported (IBNR)). Although some variability is inherent in this estimate, the Company believes that the current estimate is reasonable in all material respects. This estimate is reviewed regularly and adjusted as necessary. Adjustments related to changes in estimates are reflected in the Company’s results of operations in the period in which those estimates changed.	Use of Estimates — The most significant estimate that is susceptible to notable change in the near-term relates to the provision for unpaid losses and loss adjustment expenses (including those losses incurred but not reported (IBNR)). Although some variability is inherent in this estimate, the Company believes that the current estimate is reasonable in all material respects. This estimate is reviewed regularly and adjusted as necessary. Adjustments related to changes in estimates are reflected in the Company’s results of operations in the period in which those estimates changed.
Income taxes			Income Taxes — Where applicable, income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax-credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. Deferred tax assets are recognized to the extent that there is sufficient positive evidence as allowed under the ASC Topic 740, “Income Taxes” (“Topic 740”), to support the recoverability of those deferred tax assets. The Company establishes a valuation allowance to the extent that there is insufficient evidence to support the recoverability of the deferred tax asset under Topic 740. In making such a determination, management considers all available positive and negative evidence, including future reversals of existing taxable temporary differences, projected future taxable income, tax-planning strategies, and results of recent operations. If it is determined that the deferred tax assets would be realizable in the future in excess of their net recorded amount, an adjustment would be made to the deferred tax asset valuation allowance, which would reduce the provision for income taxes. As of December 31, 2020 and 2019, the Company did not have any unrecognized tax benefits and had no accrued interest or penalties related to uncertain tax positions. If recorded, interest and penalties would be recorded as interest expense or penalty expense in the consolidated statements of income and other comprehensive income.

Emerging growth company	Emerging growth company The Company is an “emerging growth company,” as defined in Section 2(a) of the Securities Act, as modified by the Jumpstart Our Business Startups Act of 2012 (the “JOBS Act”), and it may take advantage of certain exemptions from various reporting requirements that are applicable to other public companies that are not emerging growth companies including, but not limited to, not being required to comply with the auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act, 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 shareholder 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	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 revenues and expenses during the reporting periods. 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 September 30, 2021.
Marketable securities held in Trust Account		Marketable securities held in Trust Account At September 30, 2021, substantially all of the assets held in the Trust Account were invested in short term U.S Treasury obligations, which are carried at amortized cost. During the three months ended September 30, 2021, the Company did not withdraw any interest income from the Trust Account to pay for its franchise and income taxes.
Common stock subject to possible redemption		Common stock subject to possible redemption The Company accounts for its common stock subject to possible redemption in accordance with the guidance in Accounting Standards Codification (“ASC”) Topic 480 “Distinguishing Liabilities from Equity.” Common stock subject to mandatory redemption is classified as a liability instrument and is measured at fair value. Conditionally redeemable common stock (including common stock that features redemption rights that is either within the control of the holder or subject to redemption upon the occurrence of uncertain events not solely within the Company’s control) is classified as temporary equity. At all other times, common stock is classified as stockholders’ equity. The Company’s common stock features certain redemption rights that are considered to be outside of the Company’s control and subject to occurrence of uncertain future events.
Deferred offering costs	Deferred offering costs Deferred offering costs consist of underwriting and legal expenses incurred through the balance sheet date that are directly related to the Proposed Offering and that will be charged to shareholders equity upon the completion of the Proposed Offering. Should the Proposed Offering prove to be unsuccessful, these deferred costs, as well as additional expenses incurred, will be charged to operations.	Deferred offering costs Deferred offering costs consist of underwriting, legal, accounting and other expenses incurred through the balance sheet date that are directly related to the IPO and that are charged to shareholders equity upon the completion of the IPO. Offering costs amounting to $1,548,743 (including $1,000,000 of underwriting fees) were charged to shareholders’ equity upon the completion of the IPO. In addition, underwriters received 57,500 Units (“Underwriter Units”), with such Units restricted from sale until the closing of the Business Combination and with no redemption rights from the Trust Account. Each Underwriter Unit consists of one share of Class A common stock of the Company, par value $0.0001 per share and one
Warrant Liabilities		Warrant Liabilities The Company accounts for the 5,750,000 Public Warrants, 257,500 Private Unit Warrants, 1,300,000 OTM Warrants and 28,750 Underwriter Warrants issued in connection with the IPO and the Private Placements in accordance with the guidance contained in ASC 815-40 “Contracts in Entity’s Own Equity”. Such guidance provides that because the warrants do not meet the criteria for equity treatment thereunder, each warrant must be recorded as a non-cash liability. Accordingly, the Company classifies each warrant as a liability at its fair value. This liability is subject to re-measurement at each balance sheet date. With each such re-measurement, 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 utilizes a Monte-Carlo simulation model to value the warrants at each reporting period. The Company recorded $15,025,604 of warrant liabilities as of September 30, 2021.
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 as of December 31, 2020 and no amounts accrued for interest and penalties. The Company is currently not aware of any issues under review that could result in significant payments, accruals or material deviation from its position. The Company is subject to income tax examinations by major taxing authorities since inception. There was no provision for income taxes for the period from December 23, 2020 (inception) to December 31, 2020.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Nature of Operations — ● The Company earns commission revenues for the distribution and servicing of classic automobile and boat insurance policies written through personal and commercial lines agency agreements with multiple insurance carriers in the United States, Canada, and the United Kingdom. ● Reinsurance premiums are earned in Hagerty Reinsurance Limited (“Hagerty Re”) which is registered as a Class 3A reinsurer under the Bermuda Insurance Act 1978. Hagerty Re solely reinsures the classic auto and marine risks written through its affiliated managing general agent entities (“MGAs”) in the United States, Canada and the United Kingdom. ● The business produced by the U.S. MGAs is written by Essentia Insurance Company (“Essentia”) and reinsured with its affiliate Evanston Insurance Company (“Evanston”). In turn, Hagerty Re assumes premiums through a quota share agreement with Evanston. Essentia and Evanston are wholly owned subsidiaries of Markel. ● In 2020, Hagerty Re entered into a reinsurance agreement with Aviva Canada, Inc. (“Aviva”) to reinsure classic auto and marine risks produced by its Canadian affiliate MGA. ● In 2021, Hagerty Re entered into a reinsurance agreement with Markel International Insurance Company Limited to reinsure classic auto risks produced by its affiliate MGA in the United Kingdom. In connection with this new treaty, Hagerty Re purchased reinsurance to limit its liability to £ 1,000,000 per claim as United Kingdom (“U.K.”) law requires unlimited liability coverage. Markel International Insurance Company Limited is an affiliate of Markel. ● The Company earns subscription revenue through membership offerings and other automotive services sold to policyholders and classic vehicle enthusiasts. Membership offerings include but are not limited to private label roadside assistance, digital and linear video content, our award-winning magazine, valuation services, members-only events and exclusive automotive third-party discounts. Additionally, the Company owns and operates collector vehicle events, earning revenue through admission income and sponsorships, as well as event registration service fees on behalf of automotive and motorsport organizations to manage credentials. Revenue is also derived from the sale of merchandise and operation of a peer-to-peer classic vehicle rental business for auto enthusiasts. In 2020, the Company started a network of experience and storage centers within majority-owned world-class vehicle storage called Member Hubs Holding, LLC (MHH). Principles of Consolidation — Basis of Presentation — Business Update Related To COVID-19 The Company has taken several precautionary steps to safeguard its businesses and team members from COVID-19, including implementing travel restrictions, arranging work from home capabilities and flexible work policies. The safety and well-being of our team members continues to be the top priority. As restrictions were put in place, employees were able to transition to a work from home environment quickly and effectively due to prior technology investments and the Company’s focus on core values. Due to the restrictions and uncertainty caused by the pandemic, 2020 revenue growth was lower than expected primarily caused by lower levels of new business. Offsetting the 2020 revenue shortfall, expenses related to promotional events and travel were lower than anticipated. By the end of 2020 and as of September 2021, new business growth returned to pre-pandemic pace, events were being planned and new initiatives were on track. Management will continue to follow and monitor guidelines in each jurisdiction and is working on a phased transition of employees back to the office. Use of Estimates The most significant estimate that is susceptible to notable changes in the near-term relates to the provision for unpaid losses and loss adjustment expenses (including those losses incurred but not reported (IBNR)). Although some variability is inherent in this estimate, the Company believes that the current estimate is reasonable in all material respects. This estimate is reviewed regularly and adjusted as necessary. Adjustments related to changes in estimates are reflected in the Company’s results of operations in the period in which those estimates changed. Segment Information Fair Value of Financial Instruments Fixed Income Securities — New Accounting Standards Recently Adopted Accounting Guidance Financial Instruments The Company early adopted ASU No. 2017-12 effective January 1, 2020. Adoption of the standard enhanced the presentation of the effects of our hedging instruments and the hedged items in our condensed consolidated financial statements to increase the understandability of the results of our hedging strategies. Media Content ​ Convertible Instruments and Contracts — Recent Accounting Guidance Not Yet Adopted Credit Losses - The guidance in ASU No. 2016-13 amends Topic 326, the reporting of credit losses for assets held at amortized cost basis, eliminating the probable initial recognition threshold and replacing it with a current estimate of all expected credit losses. Estimated credit losses are recognized as a credit loss allowance reflected in a valuation account that is deducted from the amortized cost basis of the financial asset to present the net amount expected to be collected. The guidance also addresses available-for-sale securities, whereby credit losses remain measured on an incurred loss basis with the presentation of the credit losses using an allowance rather than as a write-down. ASU No. 2019-10 defers the effective date of ASU No. 2016-13 to January 1, 2023. The Company does not expect the adoption of ASU No. 2016-13 to have a material impact on the condensed consolidated financial statements and related disclosures. Leases ​ Reference Rate Reform Reference Rate Reform (Topic 848), which clarifies that certain optional expedients and exceptions in Topic 848 for contract modifications and hedge accounting apply to derivatives that are affected by the discounting transition. The Company does not expect the adoption of these ASUs to have a material impact on the condensed consolidated financial statements and related disclosures.	1.

BUSINESS COMBINATIONS AND ASSET ACQUISITIONS
BUSINESS COMBINATIONS AND ASSET ACQUISITIONS	6. BUSINESS COMBINATIONS AND ASSET ACQUISITIONS The Company’s business strategy is to attract high-quality partners to join our operations to provide expanded automotive related offerings to our members. Transactions in which the Company obtains control of a business are treated as business combinations. Acquisitions of an asset, or a group of assets, that does not meet the definition of a business are treated as an asset acquisition. In connection with asset acquisitions, the Company records the estimated value of the net tangible assets purchased and the value of the identifiable intangible assets purchased, which typically consist of purchased customer relationships, the right to renew policies upon expiration of the current policy term (renewal rights) and noncompete agreements. In connection with business combinations, the Company records the estimated value of the net tangible assets purchased and the value of the identifiable intangible assets purchased, which typically consist of purchased internally developed software, customer lists, trademarks and noncompete agreements. The valuation of purchased intangible assets involves significant estimates and assumptions. Until final valuations are complete, any change in assumptions could affect the carrying value of tangible assets, goodwill and identifiable intangible assets. Net assets and results of operations are included in the Company’s condensed consolidated financial statements commencing at the respective purchase closing dates for business combinations and asset acquisitions. 2021 Business Combinations 2020 Asset Acquisition The following table presents the allocation of the business combination and asset acquisition costs to the assets acquired based on their fair values: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Nine Months Ended ​ September 30, 2021 September 30, 2020 Cash ​ $ 8,449,763 ​ $ 2,480,634 Fair value of non-cash consideration ​ 3,767,305 ​ 7,191,259 Total consideration ​ $ 12,217,069 ​ $ 9,671,892 Allocation of purchase price: ​ ​ Property and equipment ​ $ 397,850 ​ $ — Intangible assets ​ ​ 5,571,518 ​ ​ 9,710,228 Goodwill ​ 6,333,273 ​ — Total assets acquired ​ 12,302,641 ​ 9,710,228 Liabilities assumed ​ ​ Accrued expenses ​ — ​ 38,336 Contract liabilities - current ​ ​ 85,572 ​ ​ — Total liabilities assumed ​ 85,572 ​ 38,336 Estimated fair value of net assets acquired ​ $ 12,217,069 ​ $ 9,671,892 ​	5.

On August 30, 2019, the Company entered into a business combination agreement to purchase all of the assets of 1) the antique and collector automobile and motorcycle exhibition business knows as the Greenwich Concours d’Elegance and 2) an unincorporated association known as the Madison Avenue Sports Car Driving & Chowder Society (Chowder Club). Aggregate purchase consideration for these business combinations consisted of cash paid at closing of $6,975,000 and a liability $25,000 to be paid upon trademark transfer completion. The estimated fair value of obligations related to these business combinations was $3,698,000 and will be accrued as wage expense as earned subject to continued employment. The fair value of obligations is based upon the present value of the expected future payments to be made to the sellers of the acquired businesses in accordance with the provisions outlined in the respective purchase agreements. In determining fair value, the acquired business’s future performance is estimated using financial projections developed by management for the acquired business and reflects market participant assumptions regarding revenue growth and/or profitability. 2018 Asset Acquisitions and Business Combinations — The following table presents the allocation of the business combination and asset acquisition cost to the assets acquired based on their fair values: ​ ​ ​ ​ ​ ​ ​ ​ ​ 2020 2019 Cash ​ $ 2,944,056 ​ $ 11,275,000 Fair value of non-cash consideration ​ 9,191,259 ​ 3,925,000 Total consideration ​ $ 12,135,315 ​ $ 15,200,000 Allocation of purchase price: ​ ​ Cash and cash equivalents ​ $ — ​ $ 29,519 Other current assets ​ 61,923 ​ 4,597 Intangible assets ​ 11,266,228 ​ 11,815,000 Goodwill ​ 944,000 ​ 3,365,769 Total assets acquired ​ $ 12,272,151 ​ $ 15,214,885 Liabilities assumed ​ ​ Accrued compensation – current ​ $ 38,336 ​ $ — Contract liabilities – current ​ 98,500 ​ 14,885 Total liabilities assumed ​ $ 136,836 ​ $ 14,885 Estimated fair value of net assets acquired ​ $ 12,135,315 ​ $ 15,200,000 ​

INTEREST RATE SWAP
INTEREST RATE SWAP	10. INTEREST RATE SWAP Interest rate swap agreements are contracts to exchange floating rate for fixed rate interest payments over the life of the agreement without the exchange of the underlying notional amounts. The notional amounts of the interest rate swap agreements are used to measure interest to be paid or received and do not represent the amount of exposure to credit loss. The differential paid or received on the interest rate swap agreements is recognized as an adjustment to interest expense. The purpose of the swap agreement is to fix the interest rate on a portion of the Company’s existing variable rate debt to reduce exposure to interest rate fluctuations. Under the agreement, the Company pays the counterparty interest at a fixed rate. The counterparty will pay the Company interest at a variable rate, adjusted quarterly and based on LIBOR or the alternative replacement of LIBOR. The amount exchanged is calculated based on the notional amount. Amounts shown below: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ September 30, 2021 December 31, 2020 In March 2017, the Company entered into an interest rate swap agreement with an Notional Amount ​ $ 15,000,000 ​ $ 15,000,000 original notional amount of $15,000,000 at a fixed rate of 2.20%. ​ Fair Value ​ $ (158,360) ​ $ (378,043) In December 2020, the Company entered into an interest rate swap agreement with an Notional Amount ​ $ 35,000,000 ​ $ 35,000,000 original notional amount of $35,000,000 at a fixed rate of 0.78 %. ​ Fair Value ​ $ 253,575 ​ $ (423,228) Net fair value of interest rate swap ​ $ 95,215 ​ $ (801,271) ​ The significant inputs, primarily the LIBOR forward curve, used to determine the fair value are considered Level 2 observable market inputs. The Company monitors the credit and nonperformance risk associated with its counterparties and believes them to be insignificant at September 30, 2021 and December 31, 2020.	11. INTEREST RATE SWAP

The alternative benchmark replacement rate is the secured overnight financing rate (SOFR). In addition, the facility includes a provision for determining a SOFR successor rate in the event SOFR reference rates are no longer available. If no SOFR successor rate has been determined, the rate will be based on the higher of the Prime Rate or the fed funds rate plus a fixed margin. In connection with the Credit Facility, the Company is required, among other things, to meet certain financial covenants, including a fixed-charge coverage ratio and a leverage ratio. The Company was in compliance as of September 30, 2021.	12. LONG-TERM DEBT

The valuation allowance as of September 30, 2021 has been increased for additional foreign net operating losses and adjusted for changes in foreign exchange rates. The valuation allowance is $6,714,116 and $4,770,618 as of September 30, 2021 and December 31, 2020, respectively. As of September 30, 2021 and December 31, 2020, the Company did not have any unrecognized tax benefits and had no accrued interest or penalties related to uncertain tax positions. If recorded, interest and penalties would be recorded as interest expense or penalty expense in the condensed consolidated statements of income and other comprehensive income.

The safety and well-being of our team members continues to be the top priority. As restrictions were put in place, employees were able to transition to a work from home environment quickly and effectively due to prior technology investments and the Company’s focus on core values. Due to the restrictions and uncertainty caused by the pandemic, 2020 revenue growth was lower than expected primarily caused by lower levels of new business. Offsetting the 2020 revenue shortfall, expenses related to promotional events and travel were lower than anticipated. By the end of 2020 and as of September 2021, new business growth returned to pre-pandemic pace, events were being planned and new initiatives were on track. Management will continue to follow and monitor guidelines in each jurisdiction and is working on a phased transition of employees back to the office.

Use of Estimates	Use of Estimates The most significant estimate that is susceptible to notable changes in the near-term relates to the provision for unpaid losses and loss adjustment expenses (including those losses incurred but not reported (IBNR)). Although some variability is inherent in this estimate, the Company believes that the current estimate is reasonable in all material respects. This estimate is reviewed regularly and adjusted as necessary. Adjustments related to changes in estimates are reflected in the Company’s results of operations in the period in which those estimates changed.

Cash and Cash Equivalents and Restricted Cash and Cash Equivalents		Cash and Cash Equivalents and Restricted Cash and Cash Equivalents — The Company maintains cash collected for premiums from insured parties that have not yet been remitted to insurance companies. These funds are required to be held in trust and segregated from operating cash. These funds and a corresponding liability are included in cash and due to insurers, respectively, in the accompanying consolidated balance sheets. The Company has established a trust account for the benefit of the ceding insurer as security for Hagerty Re’s obligations for losses, loss expenses, unearned premium and profit-sharing commissions. The use of this fund is restricted to the payment of these expenses.
Accounts Receivable		Accounts Receivable —
Reinsurance Premiums Ceded		Reinsurance Premiums Ceded —
Acquisition Costs		Acquisition Costs — The Company evaluates the recoverability of deferred acquisition costs by determining if the sum of future-earned premiums is greater than the expected future claims and expenses. Anticipated investment income is also a factor in this determination. If a loss is probable on the unexpired portion of policies in force, a premium deficiency loss is recognized. At December 31, 2020 and 2019, the deferred acquisition costs were considered fully recoverable and no premium deficiency loss was recorded.
Property and Equipment		Property and Equipment — three Annual depreciation is calculated based on the straight-line method. Maintenance, repair costs and minor renovations are charged to earnings, while expenditures that increase the asset lives are capitalized. Property and equipment depreciation and amortization expense were $4,693,926, $4,399,438 and $4,768,406 in 2020, 2019 and 2018, respectively. The Company reviews all property and equipment that have finite lives for impairment whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. If it is determined the carrying amount of the asset is not recoverable, an impairment charge is recorded. Upon sale or retirement, the cost and related accumulated depreciation of assets disposed of are removed from the accounts, and any resulting gain or loss is reflected in earnings.
Prepaid Expenses and Other Assets		Prepaid Expenses and Other Assets — SaaS implementation costs are recorded as incurred in prepaid expenses. The Company expenses the costs incurred during the preliminary project stage and, upon management approval, capitalizes the direct implementation costs once implementation begins. The Company monitors implementation on an ongoing basis and capitalizes the costs of any major improvements or new functionality. Once the software is fully implemented, the ongoing maintenance costs are expensed. At December 31, 2020 and 2019, there are approximately $13,300,000 and $11,740,000 of such costs in- service and capitalized as part of prepaid expenses and other assets. At December 31, 2020, there were $4,390,000 of such costs in progress that will be placed into service in 2021. At December 31, 2019, there were $3,470,000 of such costs in progress. The Company amortizes SaaS implementation costs to general and administrative services expense over the contract term including extensions where it is likely the contract will be renewed. Of the $13,300,000 in software capitalized, approximately $2,320,000 has been amortized. Approximately $2,400,000 and $12,970,000 SaaS implementation costs, net of amortization, are recorded in short-term and long-term prepaid expenses and other assets, respectively at December 31, 2020. Approximately $1,110,000 and $9,620,000 SaaS implementation costs, net of amortization, are recorded in short-term and long-term prepaid expenses and other assets, respectively at December 31, 2019. The remaining capitalized asset for 2020 will be amortized as follows: ​ ​ ​ ​ 2021 $ 1,550,000 2022 ​ 1,450,000 2023 ​ 1,040,000 2024 ​ 950,000 2025 ​ 920,000 Thereafter ​ 5,070,000

Provision for Unpaid Losses and Loss Adjustment Expenses		Provision for Unpaid Losses and Loss Adjustment Expenses — The provision for unpaid losses and loss adjustment expenses includes losses reported at the balance sheet date and an amount, based on past experience, for losses IBNR. The Company provides IBNR based on an analysis of the loss experience of the risks insured and the recommendations of appropriately qualified actuaries. The reinsurance recoverable amounts shown are determined by applying contract language specific to the Company’s third-party reinsurance program to losses and loss expenses arising from claims occurring as a result of a qualifying event. Adjustments to estimates will be included in the financial statements of subsequent periods when such adjustments become known.

Derivative Instruments		Derivative Instruments — derivative instruments (including certain derivative instruments embedded in other contracts) and whether designated in hedging relationships or not, be recorded on the consolidated balance sheet as either an asset or liability measured at fair value. If the derivative is designated as a cash flow hedge, the effective portions of changes in the fair value of the derivative are recorded in other comprehensive income and are recognized in the income statements when the hedged item affects earnings. If a derivative is not designated as an accounting hedge, the change in fair value is recognized in income in the period in which the hedged item and hedging instrument affect earnings. All derivative instruments are managed on a consolidated basis to efficiently minimize exposures. Gains and losses related to the derivative instruments are expected to be largely offset by gains and losses on the original underlying asset or liability. The Company does not use derivative financial instruments for speculative purposes. The Company is exposed to credit loss in the event of nonperformance by the counterparties on derivative contracts. It is the Company’s policy to manage its credit risk on these transactions by dealing only with financial institutions having a long-term credit rating of “A” or better and by distributing the contracts among several financial institutions to diversify credit concentration risk.

Income Taxes		Income Taxes — Where applicable, income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax-credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. Deferred tax assets are recognized to the extent that there is sufficient positive evidence as allowed under the ASC Topic 740, “Income Taxes” (“Topic 740”), to support the recoverability of those deferred tax assets. The Company establishes a valuation allowance to the extent that there is insufficient evidence to support the recoverability of the deferred tax asset under Topic 740. In making such a determination, management considers all available positive and negative evidence, including future reversals of existing taxable temporary differences, projected future taxable income, tax-planning strategies, and results of recent operations. If it is determined that the deferred tax assets would be realizable in the future in excess of their net recorded amount, an adjustment would be made to the deferred tax asset valuation allowance, which would reduce the provision for income taxes. As of December 31, 2020 and 2019, the Company did not have any unrecognized tax benefits and had no accrued interest or penalties related to uncertain tax positions. If recorded, interest and penalties would be recorded as interest expense or penalty expense in the consolidated statements of income and other comprehensive income.

New Accounting Standards	New Accounting Standards Recently Adopted Accounting Guidance Financial Instruments The Company early adopted ASU No. 2017-12 effective January 1, 2020. Adoption of the standard enhanced the presentation of the effects of our hedging instruments and the hedged items in our condensed consolidated financial statements to increase the understandability of the results of our hedging strategies. Media Content ​ Convertible Instruments and Contracts — Recent Accounting Guidance Not Yet Adopted Credit Losses - The guidance in ASU No. 2016-13 amends Topic 326, the reporting of credit losses for assets held at amortized cost basis, eliminating the probable initial recognition threshold and replacing it with a current estimate of all expected credit losses. Estimated credit losses are recognized as a credit loss allowance reflected in a valuation account that is deducted from the amortized cost basis of the financial asset to present the net amount expected to be collected. The guidance also addresses available-for-sale securities, whereby credit losses remain measured on an incurred loss basis with the presentation of the credit losses using an allowance rather than as a write-down. ASU No. 2019-10 defers the effective date of ASU No. 2016-13 to January 1, 2023.

Revenue Recognition		Revenue Recognition — Under the new standard, certain costs to obtain or fulfill a contract that were previously expensed as incurred have been capitalized. The Company capitalizes the incremental costs to obtain contracts primarily related to commission payments on new policy sales. These deferred costs are amortized over the expected life of the insurance client and are included in prepaid expenses and other assets in the Company’s consolidated balance sheet as of December 31, 2020 and 2019. Hagerty Re revenue is accounted for under ASC 944 “Financial Services — Insurance” (“Topic 944”).

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Nature of Operations — ● The Company earns commission revenues for the distribution and servicing of classic automobile and boat insurance policies written through personal and commercial lines agency agreements with multiple insurance carriers in the United States, Canada, and the United Kingdom. ● Reinsurance premiums are earned in Hagerty Reinsurance Limited (“Hagerty Re”) which is registered as a Class 3A reinsurer under the Bermuda Insurance Act 1978. Hagerty Re solely reinsures the classic auto and marine risks written through its affiliated managing general agent entities (“MGAs”) in the United States, Canada and the United Kingdom. ● The business produced by the U.S. MGAs is written by Essentia Insurance Company (“Essentia”) and reinsured with its affiliate Evanston Insurance Company (“Evanston”). In turn, Hagerty Re assumes premiums through a quota share agreement with Evanston. Essentia and Evanston are wholly owned subsidiaries of Markel. ● In 2020, Hagerty Re entered into a reinsurance agreement with Aviva Canada, Inc. (“Aviva”) to reinsure classic auto and marine risks produced by its Canadian affiliate MGA. ● In 2021, Hagerty Re entered into a reinsurance agreement with Markel International Insurance Company Limited to reinsure classic auto risks produced by its affiliate MGA in the United Kingdom. In connection with this new treaty, Hagerty Re purchased reinsurance to limit its liability to £ 1,000,000 per claim as United Kingdom (“U.K.”) law requires unlimited liability coverage. Markel International Insurance Company Limited is an affiliate of Markel. ● The Company earns subscription revenue through membership offerings and other automotive services sold to policyholders and classic vehicle enthusiasts. Membership offerings include but are not limited to private label roadside assistance, digital and linear video content, our award-winning magazine, valuation services, members-only events and exclusive automotive third-party discounts. Additionally, the Company owns and operates collector vehicle events, earning revenue through admission income and sponsorships, as well as event registration service fees on behalf of automotive and motorsport organizations to manage credentials. Revenue is also derived from the sale of merchandise and operation of a peer-to-peer classic vehicle rental business for auto enthusiasts. In 2020, the Company started a network of experience and storage centers within majority-owned world-class vehicle storage called Member Hubs Holding, LLC (MHH). Principles of Consolidation — Basis of Presentation — Business Update Related To COVID-19 The Company has taken several precautionary steps to safeguard its businesses and team members from COVID-19, including implementing travel restrictions, arranging work from home capabilities and flexible work policies. The safety and well-being of our team members continues to be the top priority. As restrictions were put in place, employees were able to transition to a work from home environment quickly and effectively due to prior technology investments and the Company’s focus on core values. Due to the restrictions and uncertainty caused by the pandemic, 2020 revenue growth was lower than expected primarily caused by lower levels of new business. Offsetting the 2020 revenue shortfall, expenses related to promotional events and travel were lower than anticipated. By the end of 2020 and as of September 2021, new business growth returned to pre-pandemic pace, events were being planned and new initiatives were on track. Management will continue to follow and monitor guidelines in each jurisdiction and is working on a phased transition of employees back to the office. Use of Estimates The most significant estimate that is susceptible to notable changes in the near-term relates to the provision for unpaid losses and loss adjustment expenses (including those losses incurred but not reported (IBNR)). Although some variability is inherent in this estimate, the Company believes that the current estimate is reasonable in all material respects. This estimate is reviewed regularly and adjusted as necessary. Adjustments related to changes in estimates are reflected in the Company’s results of operations in the period in which those estimates changed. Segment Information Fair Value of Financial Instruments Fixed Income Securities — New Accounting Standards Recently Adopted Accounting Guidance Financial Instruments The Company early adopted ASU No. 2017-12 effective January 1, 2020. Adoption of the standard enhanced the presentation of the effects of our hedging instruments and the hedged items in our condensed consolidated financial statements to increase the understandability of the results of our hedging strategies. Media Content ​ Convertible Instruments and Contracts — Recent Accounting Guidance Not Yet Adopted Credit Losses - The guidance in ASU No. 2016-13 amends Topic 326, the reporting of credit losses for assets held at amortized cost basis, eliminating the probable initial recognition threshold and replacing it with a current estimate of all expected credit losses. Estimated credit losses are recognized as a credit loss allowance reflected in a valuation account that is deducted from the amortized cost basis of the financial asset to present the net amount expected to be collected. The guidance also addresses available-for-sale securities, whereby credit losses remain measured on an incurred loss basis with the presentation of the credit losses using an allowance rather than as a write-down. ASU No. 2019-10 defers the effective date of ASU No. 2016-13 to January 1, 2023. The Company does not expect the adoption of ASU No. 2016-13 to have a material impact on the condensed consolidated financial statements and related disclosures. Leases ​ Reference Rate Reform Reference Rate Reform (Topic 848), which clarifies that certain optional expedients and exceptions in Topic 848 for contract modifications and hedge accounting apply to derivatives that are affected by the discounting transition. The Company does not expect the adoption of these ASUs to have a material impact on the condensed consolidated financial statements and related disclosures.	1.

BUSINESS COMBINATIONS AND ASSET ACQUISITIONS	6. BUSINESS COMBINATIONS AND ASSET ACQUISITIONS The Company’s business strategy is to attract high-quality partners to join our operations to provide expanded automotive related offerings to our members. Transactions in which the Company obtains control of a business are treated as business combinations. Acquisitions of an asset, or a group of assets, that does not meet the definition of a business are treated as an asset acquisition. In connection with asset acquisitions, the Company records the estimated value of the net tangible assets purchased and the value of the identifiable intangible assets purchased, which typically consist of purchased customer relationships, the right to renew policies upon expiration of the current policy term (renewal rights) and noncompete agreements. In connection with business combinations, the Company records the estimated value of the net tangible assets purchased and the value of the identifiable intangible assets purchased, which typically consist of purchased internally developed software, customer lists, trademarks and noncompete agreements. The valuation of purchased intangible assets involves significant estimates and assumptions. Until final valuations are complete, any change in assumptions could affect the carrying value of tangible assets, goodwill and identifiable intangible assets. Net assets and results of operations are included in the Company’s condensed consolidated financial statements commencing at the respective purchase closing dates for business combinations and asset acquisitions. 2021 Business Combinations 2020 Asset Acquisition The following table presents the allocation of the business combination and asset acquisition costs to the assets acquired based on their fair values: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Nine Months Ended ​ September 30, 2021 September 30, 2020 Cash ​ $ 8,449,763 ​ $ 2,480,634 Fair value of non-cash consideration ​ 3,767,305 ​ 7,191,259 Total consideration ​ $ 12,217,069 ​ $ 9,671,892 Allocation of purchase price: ​ ​ Property and equipment ​ $ 397,850 ​ $ — Intangible assets ​ ​ 5,571,518 ​ ​ 9,710,228 Goodwill ​ 6,333,273 ​ — Total assets acquired ​ 12,302,641 ​ 9,710,228 Liabilities assumed ​ ​ Accrued expenses ​ — ​ 38,336 Contract liabilities - current ​ ​ 85,572 ​ ​ — Total liabilities assumed ​ 85,572 ​ 38,336 Estimated fair value of net assets acquired ​ $ 12,217,069 ​ $ 9,671,892 ​	5.

On August 30, 2019, the Company entered into a business combination agreement to purchase all of the assets of 1) the antique and collector automobile and motorcycle exhibition business knows as the Greenwich Concours d’Elegance and 2) an unincorporated association known as the Madison Avenue Sports Car Driving & Chowder Society (Chowder Club). Aggregate purchase consideration for these business combinations consisted of cash paid at closing of $6,975,000 and a liability $25,000 to be paid upon trademark transfer completion. The estimated fair value of obligations related to these business combinations was $3,698,000 and will be accrued as wage expense as earned subject to continued employment. The fair value of obligations is based upon the present value of the expected future payments to be made to the sellers of the acquired businesses in accordance with the provisions outlined in the respective purchase agreements. In determining fair value, the acquired business’s future performance is estimated using financial projections developed by management for the acquired business and reflects market participant assumptions regarding revenue growth and/or profitability. 2018 Asset Acquisitions and Business Combinations — The following table presents the allocation of the business combination and asset acquisition cost to the assets acquired based on their fair values: ​ ​ ​ ​ ​ ​ ​ ​ ​ 2020 2019 Cash ​ $ 2,944,056 ​ $ 11,275,000 Fair value of non-cash consideration ​ 9,191,259 ​ 3,925,000 Total consideration ​ $ 12,135,315 ​ $ 15,200,000 Allocation of purchase price: ​ ​ Cash and cash equivalents ​ $ — ​ $ 29,519 Other current assets ​ 61,923 ​ 4,597 Intangible assets ​ 11,266,228 ​ 11,815,000 Goodwill ​ 944,000 ​ 3,365,769 Total assets acquired ​ $ 12,272,151 ​ $ 15,214,885 Liabilities assumed ​ ​ Accrued compensation – current ​ $ 38,336 ​ $ — Contract liabilities – current ​ 98,500 ​ 14,885 Total liabilities assumed ​ $ 136,836 ​ $ 14,885 Estimated fair value of net assets acquired ​ $ 12,135,315 ​ $ 15,200,000 ​

INTEREST RATE SWAP
INTEREST RATE SWAP	10. INTEREST RATE SWAP Interest rate swap agreements are contracts to exchange floating rate for fixed rate interest payments over the life of the agreement without the exchange of the underlying notional amounts. The notional amounts of the interest rate swap agreements are used to measure interest to be paid or received and do not represent the amount of exposure to credit loss. The differential paid or received on the interest rate swap agreements is recognized as an adjustment to interest expense. The purpose of the swap agreement is to fix the interest rate on a portion of the Company’s existing variable rate debt to reduce exposure to interest rate fluctuations. Under the agreement, the Company pays the counterparty interest at a fixed rate. The counterparty will pay the Company interest at a variable rate, adjusted quarterly and based on LIBOR or the alternative replacement of LIBOR. The amount exchanged is calculated based on the notional amount. Amounts shown below: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ September 30, 2021 December 31, 2020 In March 2017, the Company entered into an interest rate swap agreement with an Notional Amount ​ $ 15,000,000 ​ $ 15,000,000 original notional amount of $15,000,000 at a fixed rate of 2.20%. ​ Fair Value ​ $ (158,360) ​ $ (378,043) In December 2020, the Company entered into an interest rate swap agreement with an Notional Amount ​ $ 35,000,000 ​ $ 35,000,000 original notional amount of $35,000,000 at a fixed rate of 0.78 %. ​ Fair Value ​ $ 253,575 ​ $ (423,228) Net fair value of interest rate swap ​ $ 95,215 ​ $ (801,271) ​ The significant inputs, primarily the LIBOR forward curve, used to determine the fair value are considered Level 2 observable market inputs. The Company monitors the credit and nonperformance risk associated with its counterparties and believes them to be insignificant at September 30, 2021 and December 31, 2020.	11. INTEREST RATE SWAP

Business Update Related To COVID19	Business Update Related To COVID-19 The Company has taken several precautionary steps to safeguard its businesses and team members from COVID-19, including implementing travel restrictions, arranging work from home capabilities and flexible work policies. The safety and well-being of our team members continues to be the top priority. As restrictions were put in place, employees were able to transition to a work from home environment quickly and effectively due to prior technology investments and the Company’s focus on core values. Due to the restrictions and uncertainty caused by the pandemic, 2020 revenue growth was lower than expected primarily caused by lower levels of new business. Offsetting the 2020 revenue shortfall, expenses related to promotional events and travel were lower than anticipated. By the end of 2020 and as of September 2021, new business growth returned to pre-pandemic pace, events were being planned and new initiatives were on track. Management will continue to follow and monitor guidelines in each jurisdiction and is working on a phased transition of employees back to the office.	Business Update Related To COVID-19 — The Company has taken several precautionary steps to safeguard its businesses and team members from COVID-19, including implementing travel restrictions, arranging work from home capabilities and flexible work policies.

Use of Estimates	Use of Estimates The most significant estimate that is susceptible to notable changes in the near-term relates to the provision for unpaid losses and loss adjustment expenses (including those losses incurred but not reported (IBNR)). Although some variability is inherent in this estimate, the Company believes that the current estimate is reasonable in all material respects. This estimate is reviewed regularly and adjusted as necessary. Adjustments related to changes in estimates are reflected in the Company’s results of operations in the period in which those estimates changed.

The guidance also addresses available-for-sale securities, whereby credit losses remain measured on an incurred loss basis with the presentation of the credit losses using an allowance rather than as a write-down. ASU No. 2019-10 defers the effective date of ASU No. 2016-13 to January 1, 2023.
