Summary of Significant Accounting Policies	2. Basis of Presentation and Significant Accounting Policies. Basis of Presentation and Principles of Consolidation The accompanying unaudited condensed consolidated financial statements are presented in U.S. dollars in conformity with accounting principles generally accepted in the United States of America (“GAAP”) for financial information and pursuant to the rules and regulations of the SEC. Accordingly, they do not include all of the information and footnotes required by GAAP. In the opinion of management, the unaudited condensed consolidated financial statements reflect all adjustments, which include only normal recurring adjustments necessary for the fair statement of the balances and results for the period presented. Operating results for the period for the three and nine months ended September 30, 2021, are not necessarily indicative of the results that may be expected for the period ending December 31, 2021. The unaudited condensed consolidated financial statements of the Company include its wholly owned subsidiaries in connection with the proposed business combination (as described below). All inter-company accounts and transactions are eliminated in consolidation. The accompanying unaudited condensed consolidated financial statements should be read in conjunction with the audited financial statements and notes thereto included in the Form 10-K/A filed by the Company with the SEC on May 24, 2021. Restatement of Previously Reported Financial Statements In preparation of the Company’s unaudited condensed financial statements for the quarterly period ended September 30, 2021, the Company concluded it should restate its previously issued financial statements to classify all Class A common stock subject to possible redemption in temporary equity. In accordance with technical accounting guidance on redeemable equity instruments in ASC 480-10-S99, redemption provisions not solely within the control of the Company, require Class A common stock subject to redemption to be classified outside of permanent equity. The Company had previously classified a portion of its Class A common stock in permanent equity. Although the Company did not specify a maximum redemption threshold, its charter currently provides that the Company will not redeem its Public Shares in an amount that would cause its net tangible assets to be less than $5,000,001. Previously, the Company did not consider redeemable shares classified as temporary equity as part of net tangible assets. Effective with these condensed financial statements, the Company revised this interpretation to include temporary equity in net tangible assets. In connection with the change in presentation for the Class A common stock subject to possible redemption, the Company restated its earnings per share calculation to allocate income and losses shared pro rata between the two classes of shares. This presentation contemplates a Business Combination as the most likely outcome, in which case, both classes of shares participate pro rata in the income and losses of the Company. In accordance with SEC Staff Accounting Bulletin No. 99, “Materiality,” and SEC Staff Accounting Bulletin No. 108, “Considering the Effects of Prior Year Misstatements when Quantifying Misstatements in Current Year Financial Statements,” the Company evaluated the corrections and has determined that the related impact was material to the previously filed financial statements that contained the error, reported in the Company’s Quarterly Reports on Form 10-Q for the quarterly periods ended March 31, 2021 and June 30, 2021 (the “Affected Quarterly Periods”). Therefore, the Company, in consultation with its Audit Committee, concluded that the Affected Quarterly Periods should be restated to present all Class A common stock subject to possible redemption as temporary equity and to recognize accretion from the initial book value to redemption value at the time of its Initial Public Offering. As such, the Company is reporting these restatements to those periods in this quarterly report. The impact of the restatement on the financial statements for the Affected Quarterly Periods is presented below. The table below presents the effect of the financial statement adjustments related to the restatement discussed above of the Company’s previously reported unaudited condensed balance sheet as of March 31, 2021: As of March 31, 2021 (unaudited) As Reported Adjustment As Restated Total assets $ 231,036,262 $ — $ 231,036,262 Total liabilities $ 19,386,072 $ — $ 19,386,072 Class A common stock subject to possible redemption 206,650,180 23,349,820 230,000,000 Preferred stock — — — Class A common stock 233 (233) — Class B common stock 575 — 575 Additional paid-in capital 7,656,106 (7,656,106) — Accumulated deficit (2,656,904) (15,693,481) (18,350,385) Total stockholders’ equity (deficit) $ 5,000,010 $ (23,349,820) $ (18,349,810) Total Liabilities, Class A Common Stock Subject to Possible Redemption and Stockholders’ Equity (Deficit) $ 231,036,262 $ — $ 231,036,262 Shares of Class A common stock subject to possible redemption 20,665,018 2,334,982 23,000,000 Shares of Class A common stock 2,334,982 (2,334,982) — The impact on the unaudited condensed statement of stockholders’ equity is consistent with the changes to the impacted stockholders’ equity accounts described above.

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 Securities Exchange Act of 1934, as amended) 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 an election to opt out is irrevocable. We have 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, we, 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 unaudited condensed consolidated financial statements with those of 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 accountant standards used. Proposed Business Combination On June 28, 2021, the Company entered into an Agreement and Plan of Merger (as it may be amended, supplemented or otherwise modified from time to time, the “Merger Agreement”) by and among DFP, Orion Merger Sub I, Inc., a Delaware corporation and a direct, wholly-owned subsidiary of DFP (“First Merger Sub”), Orion Merger Sub II, LLC, a Delaware limited liability company and a direct, wholly-owned subsidiary of DFP (“Second Merger Sub”) and TOI Parent, Inc., a Delaware corporation (“TOI”). Refer to the Company’s Current Report on Form 8-K, and Proxy Statement/Prospectus filed with the SEC on June 29, 2021 and October 22, 2021, respectively. Use of Estimates The preparation of unaudited condensed consolidated financial statements in conformity with GAAP requires the Company’s 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 unaudited condensed consolidated financial statements and the reported amounts of revenue and expenses during the reporting period. Making estimates requires management to exercise significant judgment. It is at least reasonably possible that the estimate of the effect of a condition, situation or set of circumstances that existed at the date of the unaudited condensed consolidated financial statements, which management considered in formulating its estimate, could change in the near term due to one or more future confirming events. One of the more significant accounting estimates included in these unaudited condensed financial statements is the determination of the fair value of the derivative warrant liabilities. Accordingly, the actual results could differ significantly from those estimates. Concentration of Credit Risk Financial instruments that potentially subject the Company to concentrations of credit risk consist of cash accounts in a financial institution, which, at times, may exceed the Federal Deposit Insurance Corporation limit of $250,000, and investments held in Trust Account. The Company has not experienced losses on these accounts and management believes the Company is not exposed to significant risks on such accounts. Investments Held in Trust Account The Company’s portfolio of investments is comprised of 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 investments in money market funds that invest in U.S. government securities and generally have a readily determinable fair value, or a combination thereof. When the Company’s investments held in the Trust Account are comprised of U.S. government securities, the investments are classified as trading securities. When the Company’s investments held in the Trust Account are comprised of money market funds, the investments are recognized at fair value. Trading securities and investments in money market funds are presented on the balance sheets at fair value at the end of each reporting period. Gains and losses resulting from the change in fair value of these securities is included in interest income on investments held in the Trust Account in the accompanying unaudited condensed consolidated statements of operations. The estimated fair values of investments held in the Trust Account are determined using available market information. Cash and Cash Equivalents The Company considers all short-term investments with an original maturity of three months or less when purchased to be cash equivalents. The Company had no cash equivalents as of September 30, 2021 and December 31, 2020. Fair Value of Financial Instruments The fair value of the Company’s assets and liabilities which qualify as financial instruments under the FASB ASC Topic 820, “Fair Value Measurements,” equal or approximate the carrying amounts represented in the condensed consolidated balance sheets. Fair Value Measurements Fair value is defined as the price that would be received for sale of an asset or paid for transfer of a liability, in an orderly transaction between market participants at the measurement date. GAAP establishes a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). These tiers consist of: ● Level 1: Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities; ● Level 2: Quoted prices in markets that are not active or financial instruments for which significant inputs to models are observable (including but not limited to quoted prices for similar securities, interest rates, foreign exchange rates, volatility and credit risk), either directly or indirectly; ● Level 3: Prices or valuations that require significant unobservable inputs (including the Management’s assumptions in determining fair value measurement). In some circumstances, the inputs used to measure fair value might be categorized within different levels of the fair value hierarchy. In those instances, the fair value measurement is categorized in its entirety in the fair value hierarchy based on the lowest level input that is significant to the fair value measurement. As of September 30, 2021, the carrying values of cash, accounts payable, accrued expenses, prepaid expenses and franchise tax payable approximate their fair values due to the short-term nature of the instruments. The Company’s investments held in Trust Account are comprised of investments in U.S. Treasury securities with an original maturity of 185 days or less or investments in money market funds that comprise only U.S. Treasury securities and are recognized at fair value. The fair value of investments held in Trust Account is determined using quoted prices in active markets. Derivative Warrant Liabilities The Company does not use derivative instruments to hedge exposures to cash flow, market, or foreign currency risks. The Company evaluates all of its financial instruments, including issued stock purchase warrants, to determine if such instruments are derivatives or contain features that qualify as embedded derivatives, pursuant to ASC 480 and FASB ASC Topic 815, “Derivatives and Hedging” (“ASC 815”). The classification of derivative instruments, including whether such instruments should be recorded as liabilities or as equity, is re-assessed at the end of each reporting period. The 5,750,000 Public Warrants and the 3,733,334 Private Placement Warrants are recognized as derivative liabilities in accordance with ASC 815. Accordingly, the Company recognizes the warrant instruments as liabilities at fair value and adjusts the instruments to fair value at each reporting period. The liabilities are subject to re-measurement at each balance sheet date until exercised, and any change in fair value is recognized in the Company’s unaudited condensed consolidated statements of operations. The fair value of the Public Warrants issued in connection with the Public Offering and Private Placement Warrants were initially measured at fair value using a Monte Carlo simulation model and subsequently, the fair value of the Private Placement Warrants have been estimated using a Monte Carlo simulation model each measurement date. The fair value of Public Warrants issued in connection with the Initial Public Offering have subsequently been measured based on the listed market price of such warrants. Offering Costs Associated with the Initial Public Offering Offering costs consisted of legal, accounting, underwriting fees and other costs incurred through the Initial Public Offering that were directly related to the Initial Public Offering. Offering costs were allocated to the separable financial instruments issued in the Initial Public Offering based on a relative fair value basis, compared to total proceeds received. Offering costs associated with derivative warrant liabilities were expensed as incurred and presented as non-operating expenses in the condensed statements of operations. Offering costs associated with the Class A common stock issued were charged against the carrying value of the shares of Class A common stock upon the completion of the Initial Public Offering. The Company classifies deferred underwriting commissions as non-current liabilities as their liquidation is not reasonably expected to require the use of current assets or require the creation of current liabilities. Class A Common Stock Subject to Possible Redemption The Company accounts for its Class A common stock subject to possible redemption in accordance with the guidance in ASC Topic 480 “Distinguishing Liabilities from Equity.” Shares of Class A common stock subject to mandatory redemption (if any) are classified as liability instruments and are measured at fair value. Shares of conditionally redeemable Class A common stock (including Class A common stock that feature redemption rights that are either within the control of the holder or subject to redemption upon the occurrence of uncertain events not solely within the Company’s control) are classified as temporary equity. At all other times, shares of Class A common stock are classified as stockholders’ equity. The Company’s Class A common stock feature certain redemption rights that are considered to be outside of the Company’s control and subject to the occurrence of uncertain future events. Accordingly, as of September 30, 2021, and December 31, 2020, 23,000,000 shares of Class A common stock subject to possible redemption are presented as temporary equity, outside of the stockholders’ equity section of the Company’s condensed consolidated balance sheets. Under ASC 480-10-S99, the Company has elected to recognize changes in the redemption value immediately as they occur and adjust the carrying value of the security to equal the redemption value at the end of each reporting period. This method would view the end of the reporting period as if it were also the redemption date for the security. Effective with the closing of the Initial Public Offering, the Company recognized the accretion from initial book value to redemption amount, which resulted in charges against additional paid-in capital (to the extent available) and accumulated deficit. Net Income (Loss) Per Share of Common Stock The Company complies with accounting and disclosure requirements of FASB ASC Topic 260, “Earnings Per Share.” The Company has two classes of shares, which are referred to as Class A common stock and Class B common stock. Income and losses are shared pro rata between the two classes of shares. Net income (loss) per share of common stock is calculated by dividing the net income (loss) by the weighted average shares of common stock outstanding for the respective period. The calculation of diluted net income (loss) per share of common stock does not consider the effect of the warrants issued in connection with the Initial Public Offering and the Private Placement to purchase an aggregate of 9,483,334 shares of common stock in the calculation of diluted income (loss) per share, because their exercise is contingent upon future events and their inclusion would be anti-dilutive under the treasury stock method. As a result, diluted net income (loss) per share is the same as basic net income (loss) per share of common stock for the three and nine months ended September 30, 2021 and 2020. Accretion associated with the redeemable Class A common stock is excluded from earnings per share as the redemption value approximates fair value. The following table presents a reconciliation of the numerator and denominator used to compute basic and diluted net income (loss) per share for each class of common stock: For the Three Months Ended September 30, For the Nine Months Ended September 30 2021 2020 2021 2020 Class A Class B Class A Class B Class A Class B Class A Class B Basic and diluted net income (loss) per share of common stock: Numerator: Allocation of net income - basic $ (345,627) $ (86,407) $ (1,933,328) $ (483,332) $ (693,980) $ (173,495) $ (4,378,377) $ (1,433,857) Allocation of net income - diluted $ (345,627) $ (86,407) $ (1,933,328) $ (483,332) $ (693,980) $ (173,495) $ (4,340,374) $ (1,471,860) Denominator: Basic weighted average common shares outstanding 23,000,000 5,750,000 23,000,000 5,750,000 23,000,000 5,750,000 16,956,204 5,552,920 Diluted weighted average common shares outstanding 23,000,000 5,750,000 23,000,000 5,750,000 23,000,000 5,750,000 16,956,204 5,750,000 Basic net income (loss) per share of common stock $ (0.02) $ (0.02) $ (0.08) $ (0.08) $ (0.03) $ (0.03) $ (0.26) $ (0.26) Diluted net income (loss) per share of common stock $ (0.02) $ (0.02) $ (0.08) $ (0.08) $ (0.03) $ (0.03) $ (0.26) $ (0.26) Income Taxes The Company complies with the accounting and reporting requirements of Financial Accounting Standards Board Accounting Standard Codification, or ASC, 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. There were no unrecognized tax benefits as of September 30, 2021, and as of December 31, 2020. ASC 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 as income tax expense. No amounts were accrued for the payment of interest and penalties as of September 30, 2021, and December 31, 2020. The Company is currently not aware of any issues under review that could result in significant payments, accruals or material deviation from its position. The Company is subject to income tax examinations by major taxing authorities since inception. Recent Accounting Pronouncements In August 2020, the Financial Accounting Standards Board issued Accounting Standard Update (“ASU”) No. 2020-06, Debt—Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging—Contracts in Entity’s Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity The Company’s management does not believe that any other recently issued, but not yet effective, accounting standards updates, if currently adopted, would have a material effect on the accompanying unaudited condensed consolidated financial statements.	Note 3 — Summary of Significant Accounting Policies Basis of presentation The Company’s financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”) for financial information and pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). The Company has no subsidiaries. As described in Note 2—Restatement of Previously Issued Financial Statements, the Company’s financial statements for the period as of December 31, 2020, and the year ended December 31, 2020, as of September 30, 2020 and for the three and nine months ended September 30, 2020, as of June 30, 2020 and for the three and six months ended June 30, 2020, and as of March 31, 2020 and for the three months ended March 31, 2020 (collectively, the “2020 Affected Periods”), are restated in this Annual Report on Form 10-K/A (Amendment No. 2) (this “Annual Report”) to correct the misapplication of accounting guidance related to the redeemable Class A common stock and earnings per share in the Company’s previously issued audited and unaudited condensed financial statements for such periods. The restated financial statements are indicated as “Restated” in the audited and unaudited condensed financial statements and accompanying notes, as applicable. See Note 2—Restatement of Previously Issued Financial Statements for further discussion. Use of Estimates The preparation of the financial statements in conformity with GAAP requires the Company’s management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Making estimates requires management to exercise significant judgment. It is at least reasonably possible that the estimate of the effect of a condition, situation or set of circumstances that existed at the date of the financial statements, which management considered in formulating its estimate, could change in the near term due to one or more future conforming events. Accordingly, the actual results could differ from those estimates. Cash and Cash Equivalents The Company considers all short-term investments with an original maturity of three months or less when purchased to be cash equivalents. The Company had no cash equivalents as of December 31, 2020, and 2019. Investments Held in the Trust Account The Company’s portfolio of investments held in the Trust Account is comprised of 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 investments in money market funds that invest in U.S. government securities, or a combination thereof. The Company’s investments held in the Trust Account are classified as trading securities. Trading securities are presented on the balance sheet at fair value at the end of each reporting period. Gains and losses resulting from the change in fair value of these securities is included in net gain on investments, dividends and interest held in Trust Account in the accompanying statement of operations. The estimated fair values of investments held in the Trust Account were determined using available market information. Concentration of Credit Risk Financial instruments that potentially subject the Company to concentrations of credit risk consist of cash accounts in a financial institution, which, at times, may exceed the Federal Deposit Insurance Corporation limit of $250,000, and investments held in Trust Account. The Company has not experienced losses on these accounts and management believes the Company is not exposed to significant risks on such accounts. Fair Value of Financial Instruments Fair value is defined as the price that would be received for sale of an asset, or paid for transfer of a liability, in an orderly transaction between market participants at the measurement date. U.S. GAAP establishes a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). These tiers include: ● Level 1, defined as observable inputs such as quoted prices (unadjusted) for identical instruments in active markets; ● Level 2, defined as inputs other than quoted prices in active markets that are either directly or indirectly observable such as quoted prices for similar instruments in active markets or quoted prices for identical or similar instruments in markets that are not active; and ● Level 3, defined as unobservable inputs in which little or no market data exists, therefore requiring an entity to develop its own assumptions, such as valuations derived from valuation techniques in which one or more significant inputs or significant value drivers are unobservable. In some circumstances, the inputs used to measure fair value might be categorized within different levels of the fair value hierarchy. In those instances, the fair value measurement is categorized in its entirety in the fair value hierarchy based on the lowest level input that is significant to the fair value measurement. As of December 31, 2020, and 2019, the carrying values of cash, prepaid expenses, accounts payable, accrued expenses, accrued expenses - related party, and tax obligations approximate their fair values due to the short-term nature of the instruments. The Company’s portfolio of marketable securities held in the Trust Account is comprised mainly of investments in U.S. Treasury securities with an original maturity of 185 days or less. The fair value for trading securities is determined using quoted market prices in active markets. Offering Costs The Company complied with the requirements of the ASC 340-10-S99-1. Offering costs consist of legal, accounting, underwriting fees and other costs incurred that were directly attributable to the Initial Public Offering.. Offering costs are allocated to the separable financial instruments issued in the Initial Public Offering based on a relative fair value basis, compared to total proceeds received. Offering costs associated with warrant liabilities are expensed as incurred, presented as non-operating expenses in the statement of operations. Offering costs associated with the Public Shares were charged to the carrying value of the Class A common stock subject to possible redemption upon the completion of the Initial Public Offering. The Company classifies deferred underwriting commissions as their liquidation is not reasonably expected to require the use of current assets or require the creation of current liabilities. Derivative Warrant Liabilities The Company does not use derivative instruments to hedge its exposures to cash flow, market or foreign currency risks. Management evaluates all of the Company’s financial instruments, including issued warrants to purchase its Class A common stock, to determine if such instruments are derivatives or contain features that qualify as embedded derivatives, pursuant to ASC 480 and ASC 815-15. The classification of derivative instruments, including whether such instruments should be recorded as liabilities or as equity, is re-assessed at the end of each reporting period. The Company issued 5,750,000 warrants to purchase Class A common stock to investors in the Company’s Initial Public Offering, including the over-allotment, and simultaneously issued 3,733,334 Private Placement Warrants. All of the Company’s outstanding warrants are recognized as derivative liabilities in accordance with ASC 815-40. Accordingly, we recognize the warrant instruments as liabilities at fair value and adjust the instruments to fair value at each reporting period. The liabilities are subject to re-measurement at each balance sheet date until exercised, and any change in fair value is recognized in our statement of operations. The fair value of the Public Warrants issued in connection with the Public Offering and Private Placement Warrants were initially measured at fair value using a Monte Carlo simulation model and subsequently, the fair value of the Private Placement Warrants have been estimated using a Monte Carlo simulation model each measurement date. The fair value of Public Warrants issued in connection with the Initial Public Offering have subsequently been measured based on the listed market price of such warrants. Class A Common Stock Subject to Possible Redemption (Restated - See Note 2) The Company accounts for its Class A common stock subject to possible redemption in accordance with the guidance in ASC Topic 480 “Distinguishing Liabilities from Equity.” Class A common stock subject to mandatory redemption (if any) is classified as liability instruments and are measured at fair value. Conditionally redeemable Class A common stock (including Class A common stock that features redemption rights that are either within the control of the holder or subject to redemption upon the occurrence of uncertain events not solely within the Company’s control) are classified as temporary equity. At all other times, Class A common stock is classified as stockholders’ equity. The Company’s Class A common stock feature certain redemption rights that are considered to be outside of the Company’s control and subject to the occurrence of uncertain future events. Accordingly, as of December 31, 2020, 23,000,000 shares of Class A common stock subject to possible redemption are presented as temporary equity, outside of the stockholders’ equity section of the Company’s balance sheets. Under ASC 480-10-S99, the Company has elected to recognize changes in the redemption value immediately as they occur and adjust the carrying value of the security to equal the redemption value at the end of each reporting period. This method would view the end of the reporting period as if it were also the redemption date for the security. Accordingly, effective with the closing of the Initial Public Offering, the Company recognized the accretion from the initial book value to redemption amount, which resulted in charges against paid-in -capital (to the extent available) and accumulated deficit The Class A common stock subject to possible redemption reflected on the balance sheet is reconciled on the following table: Gross proceeds $ 230,000,000 Less: Amount allocated to Public Warrants (6,727,500) Class A common stock issuance costs (10,110,406) Plus: Accretion of carrying value to redemption value 16,837,906 Class A common stock subject to possible redemption $ 230,000,000 Net Income (Loss) Per Share of Common Stock The Company complies with accounting and disclosure requirements of FASB ASC Topic 260, “Earnings Per Share.” The Company has two classes of shares, which are referred to as Class A common stock and Class B common stock. Income and losses are shared pro rata between the two classes of shares. Net income (loss) per share of common stock is calculated by dividing the net income (loss) by the weighted average number of common stock outstanding for the respective period. The calculation of diluted net income (loss) per share of common stock does not consider the effect of the warrants underlying the Units sold in the Initial Public Offering and the Private Placement to purchase an aggregate of 9,483,334 of the Company’s Class A common stock in the calculation of diluted income per share, since their exercise is contingent upon future events and their inclusion would be anti-dilutive under the treasury stock method. Accretion associated with the redeemable Class A common stock is excluded from earnings per share as the redemption value approximates fair value. The table below presents a reconciliation of the numerator and denominator used to compute basic and diluted net loss per share of common stock for each class of common stock: For the Year Ended December 31, 2020 2019 Class A Class B Class A Class B Basic and diluted net income (loss) per share of common stock: Numerator: Allocation of net income $ (6,399,368) $ (1,940,536) $ — $ (2,300) Denominator: Basic and diluted weighted average common shares outstanding 18,475,410 5,602,459 — 5,000,000 Basic and diluted net income (loss) per share of common stock $ (0.35) $ (0.35) $ — $ — Income Taxes The Company complies with the accounting and reporting requirements of Financial Accounting Standards Board Accounting Standard Codification, or FASB ASC, 740, “Income Taxes,” which requires an asset and liability approach to financial accounting and reporting for income taxes.

No amounts were accrued for the payment of interest and penalties as of December 31, 2020 or 2019. The Company is currently not aware of any issues under review that could result in significant payments, accruals or material deviation from its position. The Company is subject to income tax examinations by major taxing authorities since inception. Recent Accounting Pronouncements 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.
TOI Parent Inc.
Summary of Significant Accounting Policies	Note 2. Summary of Significant Accounting Policies Unaudited Interim Financial Information The accompanying interim condensed consolidated financial statements are unaudited and have been prepared in accordance with Article 10 of Regulation S-X issued by the Securities and Exchange Commission (“SEC”). Accordingly, they do not include all of the information and note disclosures required by U.S. generally accepted accounting principles (“GAAP”) for complete financial statements. However, the Company believes that the disclosures are adequate to make that information not misleading. In the opinion of management, all adjustments (of normal and recurring nature) considered necessary for fair presentation have been reflected in these interim statements. As such, the information included in the accompanying unaudited interim condensed consolidated financial statements should be read in conjunction with the Company’s audited consolidated financial statements and notes as of, and for the year ended December 31, 2020, issued on June 27, 2021. Principles of Consolidation The accompanying unaudited condensed consolidated financial statements include the accounts of TOI Parent, its subsidiaries, all of which are controlled by the Parent through majority voting control or are variable interest entities (“VIEs”) for which TOI Parent (through TOI Management) is the primary beneficiary. The Company consolidates entities in which it has a controlling financial interest based on either the variable interest entity or voting interest model. All significant intercompany balances and transactions have been eliminated in consolidation. Variable Interest Entities The Company consolidates entities for which it has a variable interest and is determined to be the primary beneficiary. Noncontrolling interests in less-than-wholly-owned consolidated subsidiaries of the Company are presented as a component of total equity, to the extent they are material, to distinguish between the interests of the Company and the interests of the noncontrolling owners. Revenues, expenses, and income from these subsidiaries are included in the consolidated amounts as presented on the consolidated statements of operations. The Company holds variable interests in clinical practices, for which it cannot legally own, as a result of entering into master services agreements (“MSAs”) with such practices. TOI Parent holds a variable interest in TOI CA, which is a VIE. The Company is the primary beneficiary of TOI CA and thus, consolidates TOI CA in its financial statements. Further, as a result of the February 2021 acquisition, discussed in Note 16, the Company holds an additional variable interest in TOI FL, which was determined to be a VIE. The Company determined that it is a primary beneficiary of TOI FL and thus, consolidates the entity in its financial statements. As discussed in Note 17, the shareholders of the Company’s consolidating VIEs own a minority of the issued and outstanding common shares of the Company. Business Combinations The Company accounts for all transactions that represent business combinations using the acquisition method of accounting under Accounting Standards Codification Topic No. 805, Business Combinations Segment Reporting The Company presents the financial statements by segment in accordance with Accounting Standard Codification Topic No. 280, Segment Reporting reporting Use of Estimates The preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates under different assumptions or conditions. Significant items subject to such estimates and assumptions include estimated accounts receivable, useful lives and recoverability of long-lived and intangible assets, recoverability of goodwill, fair values of acquired assets and assumed liabilities in business combinations, fair value of goodwill, judgements related to revenue recognition, and deferred income taxes. Net Income (Loss) Per Share The Company has not issued substantive common shares since inception. The Company’s Series A Preferred Shares are considered in-substance common stock since the net income (loss) of the Company is attributable to the Series A Preferred shareholders, and therefore, they are included in the denominator to calculate net income (loss) per share. Basic net income (loss) per share is calculated by dividing net income (loss) attributable to TOI Parent, Inc. by the weighted average Series A Preferred Shares, on an as-converted basis (see Note 19), and common shares issued and outstanding during the period. Diluted net income (loss) per share is calculated by dividing net income (loss) by the weighted average number of Series A Preferred Shares and common shares used in the basic income (loss) per share calculation plus the number of potential common shares that would be issued assuming exercise of all potentially dilutive instruments. Potentially dilutive instruments are excluded from the calculation of diluted income (loss) per share if the effect of including such instruments is anti-dilutive. Given the Company incurred a net loss in each period presented, the stock options outstanding during each period are anti-dilutive. As such, diluted net loss per share is the same as basic net loss per share for each period presented. Emerging Growth Company Pursuant to the special purpose acquisition company (“SPAC”) transaction described in Note 22, the Company anticipates qualifying as an “emerging growth company,” as defined in Section 2(a) of the Securities Act of 1933, 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. 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. Recently Issued Accounting Standards In June 2020, the FASB issued Accounting Standards Update 2020-05, Leases (Topic 842), Effective Dates for Certain Entities Leases (Topic 842) Financial Instruments — Credit Losses (Topic 326), Derivatives and Hedging (Topic 815), and Leases (Topic 842): Effective Dates In February 2016, the FASB issued ASU 2016-02, which amends the existing accounting standards for leases. The new standard requires lessees to record a right-of-use (“ROU”) asset and a corresponding lease liability on the balance sheet (with the exception of short-term leases), whereas under current accounting standards the Company’s lease portfolio consists primarily of operating leases and is not recognized on its consolidated balance sheets. The Company will adopt ASC 842 effective January 1, 2022, using the alternative modified transition method and will record a cumulative-effect adjustment to the opening balance of retained earnings as of that date. Prior periods will not be restated. The Company believes the largest impact will be on the consolidated balance sheets for the accounting of facilities-related leases, which represents a majority of its operating leases it has entered into as a lessee. These leases will be recognized under the new standard as ROU assets and operating lease liabilities. The Company will also provide expanded disclosures for its leasing arrangements. The results of operations are not expected to significantly change after adoption of the new standard.

Summary of Significant Accounting Policies Basis of Presentation The accompanying consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”). During fiscal year 2018, the Company presents financial information for the Practice for the period from January 1, 2018 through September 19, 2018 (“Predecessor Period”) and for the Company for the period from September 20, 2018 through December 31, 2018 (“Successor Period”). Principles of Consolidation The accompanying consolidated financial statements include the accounts of TOI Parent, its subsidiaries, all of which are controlled by TOI Parent through majority voting control, and a variable interest entity (“VIE”) for which TOI Parent (through TOI Management) is the primary beneficiary. The Company consolidates entities in which it has a controlling financial interest based on either the variable interest entity or voting interest model. All significant intercompany balances and transactions have been eliminated in consolidation. Variable Interest Entities The Company consolidates entities for which it has a variable interest and is determined to be the primary beneficiary. Noncontrolling interests in less-than-wholly-owned consolidated subsidiaries of the Company are presented as a component of total equity to distinguish between the interests of the Company and the interests of the noncontrolling owners. Revenues, expenses, and net income from these subsidiaries are included in the consolidated amounts as presented on the consolidated statements of operations. The Company holds a variable interest in the Practice as a result of entering into a master services agreement (“MSA”) in conjunction with the acquisition in September of 2018. As a result of the acquisition, HHHC is now a wholly-owned subsidiary of TOI Parent, the Practice is now a VIE of TOI Parent, as discussed in Note 17, and the Practice shareholders own a minority of the issued and outstanding common shares of the Company. Business Combinations The Company accounts for all transactions that represent business combinations using the acquisition method of accounting under Accounting Standards Codification Topic No. 805, Business Combinations Segment Reporting The Company presents the financial statements by segment in accordance with Accounting Standard Codification Topic No. 280, Segment Reporting Use of Estimates The preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates under different assumptions or conditions. Significant items subject to such estimates and assumptions include estimated accounts receivable, useful lives and recoverability of long-lived and intangible assets, recoverability of goodwill, fair values of acquired assets and assumed liabilities in business combinations, fair value of goodwill, fair value of share-based compensation, judgements related to revenue recognition, and deferred income taxes. Net Loss Per Share The Company has not issued substantive common shares since inception. The Company’s Series A Preferred Shares are considered as in-substance common stock as the net loss of the Company is attributable to the Series A Preferred shareholders, and therefore, they are included in the denominator to calculate net loss per share. Basic net loss per share is calculated by dividing net loss attributable to TOI Parent, Inc. by the weighted average Series A Preferred Shares, on an as-converted basis (see Note 19), and common shares issued and outstanding during the period. Diluted net income (loss) per share is calculated by dividing net income (loss) by the weighted-average number of Series A Preferred Shares and common shares used in the basic income (loss) per share calculation plus the number of potential common shares that would be issued assuming exercise of all potentially dilutive instruments. Potentially dilutive instruments are excluded from the calculation of diluted income (loss) per share if the effect of including such instruments is anti- dilutive. Given the Company incurred a net loss in each period presented, the stock options outstanding during each period are anti-dilutive. As such, diluted net loss per share is the same as basic net loss per share for each period presented. Revenue Recognition The Company follows the accounting requirements of Accounting Standard Codification Topic No. 606, Revenue from Contracts with Customers 1. Identification of the contract, or contracts, with a customer. 2. Identification of the performance obligations in the contract. 3. Determination of the transaction price. 4. Allocation of the transaction price to the performance obligations in the contract. 5. Recognition of revenue when, or as, we satisfy a performance obligation. The Company receives payments from the following sources for services rendered: (i) commercial insurers; (ii) the federal government under the Medicare program administered by the Centers for Medicare and Medicaid Services (“CMS”); (iii) state governments under the Medicaid and other programs; (iv) other third-party payors (e.g., hospitals and independent practice associations [“IPAs”]); and (v) individual patients and clients. Revenue primarily consists of capitation revenue, fee-for-service (“FFS”) revenue, dispensary revenue, and clinical trials revenue. Revenue is recognized in the period in which services are rendered or the period in which the Company is obligated to provide services. The form of billing and related risk of collection for such services may vary by type of revenue and the payor. The following paragraphs provide a summary of the principal forms of the Company’s billing arrangements and how revenue is recognized for each. Capitation Capitation revenues of the Company consist primarily of fees for medical services provided to patients by the Company under a capitated arrangement with various managed care organizations. Capitation revenue is paid monthly to the Company based on the number of enrollees assigned to the Company by the contracted managed care organization (per member, per month; or “PMPM”). Capitation contracts generally have a legal term of one year or longer. Capitation contracts have a single performance obligation that is a stand ready obligation to perform healthcare services to the population of enrolled members and constitutes a series for the provision of managed healthcare services for the term of the contract, which is deemed to be one month since the mix of patient-customers can and do change month over month. The transaction price for capitation contracts is variable as it primarily includes PMPM fees associated with unspecified membership that fluctuates throughout the contract. The Company generally estimates the transaction price using the most likely methodology and amounts are only included in the transaction price to the extent that it is probable that a significant reversal of cumulative revenue will not occur once any uncertainty is resolved. Certain contracts include terms for a capitation deduction where the cost of out-of-network referrals of members by the Company are deducted from the future payment. The deductions vary depending on the payor and are often not known until a future period. As such, the Company adjusts the transaction price for capitation deductions based on historic experience such that the amount of capitation revenue is constrained to the extent that it is not probable a significant reversal of revenue will occur in the future. Revenue is recognized in the month services are rendered on the basis of the transaction price established at that time. If subsequent information resolves uncertainties related to the transaction price, adjustments will be recognized in the period they are resolved. When payment has been received but services have not yet been rendered, the payment is recognized as a contract liability. Fee-for-Service Revenue FFS revenue represents revenue earned under contracts in which the Company bills and collects for medical services rendered by the Company’s employed physicians. The terms for FFS contracts are short in duration and only last for the period over which services are rendered (typically, one day). FFS revenue consists of fees for medical services provided to patients. These medical services are distinct since the patient can benefit from the medical services on their own. Each service constitutes a single performance obligation for which the patient accepts and receives the benefit of the medical services as they are performed. Under the FFS arrangements, the Company bills third-party payors and patients for patient care services provided and receives payment. Payments for services provided are generally less than billed charges. The Company records revenue net of an allowance for contractual adjustments, which represents the net revenue expected to collected from third-party payors (including managed care, commercial, and governmental payors such as Medicare and Medicaid), and patients. These expected collections are based on fees and negotiated payment rates in the case of third-party payors, the specific benefits provided for under each patient’s healthcare plans, mandated payment rates in the case of Medicare and Medicaid programs, and historical cash collections (net of recoveries). The transaction price from FFS arrangements is variable in nature because fees are based on patient encounters, credits due to patients, and reimbursement of provider costs, all of which can vary from period to period. The Company estimates the transaction price using the most likely methodology and amounts are only included in the net transaction price to the extent that it is probable that a significant reversal of cumulative revenue will not occur once any uncertainty is resolved. As a practical expedient, the Company adopted a portfolio approach to determine the transaction price for the medical services provided under FFS arrangements. Under this approach, the Company bifurcated the types of services provided and grouped health plans with similar fees and negotiated payment rates. At these levels, portfolios share the characteristics conducive to ensuring that the results do not materially differ from the standard applied to individual patient contracts related to each medical service provided. The recognition of net revenue (gross charges less contractual allowances) from such services is dependent on such factors as proper completion of medical charts following a patient visit, the forwarding of such charts to the Company’s billing center for medical coding and entering into the Company’s billing system, and the verification of each patient’s submission or representation at the time services are rendered as to the payor(s) responsible for payment of such services. Revenue is recorded on the date the services are rendered based on the information known at the time of entering of such information into the Company’s billing systems as well as an estimate of the revenue associated with medical services. When the performance obligation is not satisfied, the billing is recognized as a contract liability. Dispensary The Company sells oral prescription drugs directly through its dispensaries. Each prescription filled and delivered to the customer is a distinct performance obligation. The transaction price for the prescriptions is based on fee schedules set by various pharmacy benefit managers (“PBMs”) and other third party payors. The fee schedule is often subject to direct and indirect remuneration (“DIR”) fees, which are based primarily on pre-established metrics. DIR fees may be assessed in periods after payments are received against future payments. The Company estimates DIR fees to arrive at the transaction price for prescriptions. The Company recognizes revenue based on the transaction at the time the customer takes possession of the oral drug. Clinical Trials Revenue The Company enters into contracts to perform clinical research trials. The terms for clinical trial contracts last many months as the clinical research is performed. Each contract represents a single, integrated set of research activities and thus is a single performance obligation. The performance obligation is satisfied over time as the output is captured in data and documentation that is available for the customer to consume over the course of arrangement and furthers progress of the clinical trial. Under the clinical trial contracts, the Company receives a fixed payment for administrative, set-up, and close-down fees; a fixed amount for each patient site visit; and certain expense reimbursements. Under ASC 606, the Company has elected to recognize revenue for these arrangements using the ‘as-invoiced’ practical expedient. The Company invoices the customer periodically based on the progress of the trial such that each invoice captures the revenue earned to date based on the state of the trial as established between the Company and the customer. Direct Costs of Sales Direct cost of sales primarily consists of wages paid to clinical personnel and other health professionals, oral and IV drug costs, and other medical supplies used to provide patient care. The Company’s costs for clinical personnel wages are expensed as incurred and the Company’s costs for inventory and medical supplies are expensed when used, generally by applying the specific identification method. Cash Cash consists of deposits with banking institutions. The carrying value of the Company’s cash approximates fair value due to the short-term maturity of these instruments (less than three months). Accounts Receivable The Company accounts for accounts receivable under Accounting Standard Codification Topic No. 310, Receivables For third-party payors including Medicare, Medicaid, managed care providers, and commercial payors, the collectable amount is based on the estimated contractual reimbursement percentage, which is based on current contract prices or historical paid claims data by payor. For self-pay accounts receivable, which includes patients who are uninsured and the patient responsibility portion for patients with insurance, the collectable amount is determined using estimates of historical collection experience without regard to aging category.These estimates are adjusted for estimated conversions of patient responsibility portions, expected recoveries, and any anticipated changes in trends. Accounts receivable can be impacted by the effectiveness of the Company’s collection efforts.Additionally, significant changes in payor mix, business office operations, economic conditions, or trends in federal and state governmental healthcare coverage could affect the collectable amount of accounts receivable. The Company maintains reserves for potential credit losses on accounts receivable. Management reviews the composition of accounts receivable and analyzes historical bad debts, customer concentrations,customer credit worthiness, current economic trends, and changes in customer payment patterns to evaluate the adequacy of these reserves. The Company also regularly analyzes the ultimate collectability of accounts receivable after certain stages of the collection cycle using a look-back analysis to determine the amount of receivables subsequently collected, and adjustments are recorded when necessary. The Company continuously monitors its collections of receivables and its policy is to write off receivables when they are determined to be uncollectible. As of December 31, 2020 and 2019, the Company does not have an allowance for doubtful accounts. Inventories The Company accounts for inventory under Accounting Standard Codification Topic No. 330, Inventory The Company receives purchase discounts on products purchased. Contractual arrangements with vendors, including manufacturers and wholesalers, normally provide for the Company to receive purchase discounts from established list prices in one, or a combination, of the following forms: (i) a direct discount at the time of purchase or (ii) a discount for the prompt payment of invoices. Additionally, in other circumstances, the Company may receive rebates when products are purchased indirectly from a manufacturer (e.g., through a wholesaler). These rebates are recognized when intravenous chemotherapy drugs and oral prescription drugs are dispensed and are generally calculated by manufacturers within 30 days after the end of each completed quarter. The Company also receives additional rebate under its wholesaler contracts if it exceeds contractually defined annual purchase volumes. Purchase rebates are recorded as reductions to cost of services. Property and Equipment, net The Company accounts for property and equipment under Accounting Standard Codification Topic No. 360, Property, Plant, and Equipment When events or changes in circumstances indicate that the carrying amount of long-lived assets, including property and equipment, or other long-lived assets, may not be recoverable, an evaluation of the recoverability of currently recorded costs is performed. When an evaluation is performed, the estimated value of undiscounted future net cash flows associated with the asset groups is compared to the asset groups’ carrying value to determine if a write-down to fair value is required. If such assets are considered to be impaired, the impairment to be recognized is measured as the amount by which the carrying amount of the asset group exceeds the fair value of the assets. There were no impairment adjustments recorded for long- lived assets during the years ended December 31, 2020, 2019, the Successor Predecessor Accounts Payable, Accrued Expenses, and Other Current Liabilities Accounts payable primarily consists of unpaid invoices related to routine operating expenses. Accrued expenses and other current liabilities primarily consist of accruals made for payroll expenses, deferred capitation, and FFS revenue. Leases Lease agreements are evaluated to determine whether they are capital or operating leases in accordance with Accounting Standards Codification, Topic No. 840, Leases Goodwill and Intangible Assets The Company accounts for goodwill and intangible assets under Accounting Standards Codification Topic No. 350, Goodwill and Other Goodwill is not amortized but is required to be evaluated for impairment at the same time every year. The Company performs its annual testing of impairment for goodwill in the fourth quarter of each year. When impairment indicators are identified, the Company compares the reporting unit’s fair value to its carrying amount, including goodwill. An impairment loss is recognized as the difference, if any, between the reporting unit’s carrying amount and its fair value to the extent the difference does not exceed the total amount of goodwill allocated to the reporting unit. The Company performed a qualitative analysis and determined that no indicators of impairment existed at December 31, 2020 and 2019 and therefore, there was no goodwill impairment charge during the years ended December 31, 2020, 2019, and the Successor Period, as a result of the Company’s annual impairment evaluation. Under ASC 350, finite-lived intangible assets are stated at acquisition-date fair value. Intangible assets are amortized using the straight-line method. Finite-lived intangible assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. When circumstances indicate that recoverability may be impaired, the Company assesses its ability to recover the carrying value of the asset group from the expected future pre-tax cash flows (undiscounted and without interest charges) of the related operations. If these cash flows are less than the carrying value of such asset, an impairment loss is recognized for the difference between estimated fair value and carrying value. Fair value is determined based on appropriate valuation techniques. The Company performed a qualitative analysis and determined that there were no indicators of impairment of its finite-lived intangible assets during the years ended December 31, 2020, 2019, and the Successor Period. Debt The Company accounts for debt net of debt issuance costs. Debt issuance costs are capitalized, netted against the related debt for presentation purposes, and amortized to interest expense over the terms of the related debt using the effective interest method. Income Taxes The Company accounts for income taxes under the asset and liability method under Accounting Standards Codification Topic No. 740, Income Taxes Share-Based Compensation Plan The Company accounts for share-based compensation under Accounting Standards Codification Topic No. 718, Stock Based Compensation Excess tax benefits of awards related to stock option exercises are recognized as an income tax benefit in the statement of operations and reflected in operating activities in the statement of cash flows. Commitments and Contingencies The Company accounts for contingent liabilities under Accounting Standards Codification Subtopic No. 450-20, Contingencies Fair Value Measurements The Company accounts for fair value measurements under Accounting Standards Codification Topic No. 820, Fair Value Measurements ● Level 1 inputs: Unadjusted quoted prices in active markets for identical assets or liabilities accessible to the reporting entity at the measurement date. ● Level 2 inputs: Other than quoted prices included in Level 1 inputs that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the asset or liability. ● Level 3 inputs: Unobservable inputs for the asset or liability used to measure fair value to the extent that observable inputs are not available, thereby allowing for situations in which there is little, if any, market activity for the asset or liability at measurement date.

Significant Risks and Uncertainties Including Business and Credit Concentrations
Significant Risks and Uncertainties Including Business and Credit Concentrations	Note 3. Significant Risks and Uncertainties Including Business and Credit Concentrations Interest Rate Risk The London Interbank Offered Rate (“LIBOR”) may be eliminated in the near future. It is expected that a number of banks currently reporting information used to set LIBOR will stop doing so at the end of 2021 when their reporting commitments end. This will either end the publication of LIBOR immediately or degrade its quality such that it would no longer be a relevant metric to the Company. Change in LIBOR could affect the interest rates of the revolving credit facility and unsecured note payable. If LIBOR is no longer available, the Company will pursue alternative interest rate calculations in its revolving credit facility and unsecured note payable. However, if no alternative can be determined, the LIBOR rate component will no longer be used in determining the rates. As of September 30, 2021 and December 31, 2020, the potential effect of no longer using the LIBOR rate component to the Company’s interest rates would not have had a material effect on the interest rate in the credit facility or the note, thus the discontinuation of LIBOR is not expected to have a material effect on the Company’s financial statements. Credit Risk Financial instruments that potentially subject the Company to concentrations of credit risk consist primarily of cash and accounts receivable. Cash accounts in a financial institution may, at times, exceed the Federal Deposit Insurance Corporation (“FDIC”) coverage of $250,000 per account. The Company has not experienced losses on these accounts, and management believes the Company is not exposed to significant risks on such accounts. The Company’s accounts receivable has implicit collection risk. The Company grants credit without collateral to their patients, most of whom are local residents and are insured under third-party payor agreements. The Company believes this risk is partially mitigated by the Company’s establishment of long-term agreements and relationships with third-party payors that provide the Company with insight into historic collectability and improve the collections process. Revenue Concentration Risk The concentration of net revenue on a percentage basis for major payors at September 30, 2021 and 2020 are as follows: Nine Months Ended September 30, 2021 2020 Percentage of net revenue: Payor A 17 % 15 % Payor B 14 % 15 % The concentration of gross receivables on a percentage basis for major payors at September 30, 2021 and December 31, 2020 are as follows: September 30, December 31, 2021 2020 Percentage of gross receivables: Payor B 21 % 11 % Payor D 22 % 21 % All of the Company’s revenue is generated from customers located in the United States. Vendor Concentration Risk The concentration of cost of sales on a percentage basis for major vendors at September 30, 2021 and 2020 are as follows: Nine Months Ended September 30, 2021 2020 Percentage of cost of sales: Vendor A 51 % 54 % Vendor B 48 % 44 % The concentration of gross payables on a percentage basis for major vendors at September 30, 2021 and December 31, 2020 are as follows: September 30, December 31, 2021 2020 Percentage of gross payables: Vendor A 30 % 42 % Vendor B 59 % 48 % COVID-19 Pandemic In January 2020, the Secretary of the U.S. Department of Health and Human Services (“HHS”) declared a national public health emergency due to a novel strain of coronavirus (“COVID-19”). In March 2020, the World Health Organization declared the outbreak of COVID-19, a disease caused by this coronavirus, a pandemic. The resulting measures to contain the spread and impact of COVID-19 and other developments related to COVID-19 affected the Company’s results of operations during 2020. Where applicable, the impact resulting from the COVID-19 pandemic during the nine months ended September 30, 2021, has been considered, including updated assessments of the recoverability of assets and evaluation of potential credit losses. As a result of the COVID-19 pandemic, federal and state governments have passed legislation, promulgated regulations, and taken other administrative actions intended to assist healthcare providers in providing care to COVID-19 and other patients during the public health emergency. Sources of relief include the Coronavirus Aid, Relief and Economic Security Act (the “CARES Act”), which was enacted on March 27, 2020, the Paycheck Protection Program and Health Care Enhancement Act (the “PPPHCE Act”), which was enacted on April 24, 2020, and the Consolidated Appropriations Act, 2021 (the “CAA”), which was enacted on December 27, 2020. In total, the CARES Act, PPPHCE Act, and the CAA authorize $178 billion in funding to be distributed to hospitals and other healthcare providers through the Public Health and Social Services Emergency Fund (the “PHSSEF”). In addition, the CARES Act provides for an expansion of the Medicare Accelerated and Advance Payment Program whereby inpatient acute care hospitals and other eligible providers were able to request accelerated payment of up to 100% of their Medicare payment amount for a six-month period to be repaid through withholding of future Medicare fee-for-service payments. Various other state and local programs also exist to provide relief, either independently or through distribution of monies received via the CARES Act. During the nine months ended September 30, 2021 and the year ended December 31, 2020, the Company was a beneficiary of these stimulus measures. The Company received $4,992,758 in Paycheck Protection Program (“PPP”) loans under the CARES Act. PPP loans may be eligible for forgiveness if the funds were used for eligible payroll costs, payments on business mortgage interest payments, rent, or utilities during either the 8- or 24-week period after disbursement (see Note 11). The Company has elected to account for the loans as current debt until such loans are forgiven. Forgiveness was received during the nine months ended September 30, 2021, and as such, the Company recognized the loan principal balance and accrued interest as a gain on debt extinguishment in the condensed consolidated income statements. The Company received $2,726,856 from CMS under the Accelerated and Advance Payment Program which is an advance on future Medicare payments and will be recouped from future payments due to the Company by Medicare after 120 days. Effective October 1, 2020, the program was amended such that providers are required to repay accelerated payments beginning one year after the payment was issued. After such one-year period, Medicare payments owed to providers will be recouped against Medicare payments according to the repayment terms. As of September 30, 2021 and December 31, 2020, the Medicare accelerated payments are reflected within accrued expenses and other current liabilities in the consolidated balance sheets. The $2,726,856 is expected to be fully recouped by the first quarter of 2022. The Company received funding from United States Department of HHS as part of the Provider Relief Funding under the CARES Act. Provider Relief Funding is paid in the form of a grant and does not require repayment if used to cover lost revenue, as defined, attributable to COVID-19 and healthcare-related expenses, as defined, including qualifying direct labor, paid or purchased to prevent, prepare for, and respond to COVID-19.

The resulting measures to contain the spread and impact of COVID-19 and other developments related to COVID-19 have affected the Company’s results of operations during 2020. Where applicable, the impact resulting from the COVID-19 pandemic during the year ended December 31, 2020, has been considered, including updated assessments of the recoverability of assets and evaluation of potential credit losses. As a result of the COVID-19 pandemic, federal and state governments have passed legislation, promulgated regulations, and taken other administrative actions intended to assist healthcare providers in providing care to COVID-19 and other patients during the public health emergency. Sources of relief include the Coronavirus Aid, Relief and Economic Security Act (the “CARES Act”), which was enacted on March 27, 2020, the Paycheck Protection Program and Health Care Enhancement Act (the “PPPHCE Act”), which was enacted on April 24, 2020, and the Consolidated Appropriations Act, 2021 (the “CAA”), which was enacted on December 27, 2020. In total, the CARES Act, PPPHCE Act and the CAA authorize The Company received $4,992,758 in Paycheck Protection Program (“PPP”) loans under the CARES Act. PPP loans may be eligible for forgiveness if the funds were used for eligible payroll costs, payments on business mortgage interest payments, rent, or utilities during either the 8- or 24-week period after disbursement (see Note 11). The Company has elected to account for the loans as current debt until such loans are forgiven. The Company received $2,726,856 from CMS under the Accelerated and Advance Payment Program which is an advance on future Medicare payments and will be recouped from future payments due to the Company by Medicare after 120 days. Effective October 1, 2020, the program was amended such that providers are required to repay accelerated payments beginning one year after the payment was issued. After such one-year period, Medicare payments owed to providers will be recouped against Medicare payments according to the repayment terms. As of December 31, 2020, the entire $2.4 million of Medicare accelerated payments are reflected within accrued expenses and other current liabilities in the consolidated balance sheet. The Company expects the $2,726,856 will be fully recouped during 2021. The Company received $978,150 from United States Department of HHS as part of the Provider Relief Funding under the CARES Act. Provider Relief Funding is paid in the form of a grant and does not require repayment if used to cover lost revenue, as defined, attributable to COVID-19 and healthcare- related expenses, as defined, including qualifying direct labor, paid or purchased to prevent, prepare for, and respond to COVID-19.

The Company uses inputs such as actual trade data, quoted market prices from dealers or brokers, and other similar sources to determine the fair value of its investments. The fair value of Public Warrants issued in connection with the Initial Public Offering are measured based on the listed market price of such warrants, a quoted price in an active market, a Level 1 measurement. The fair value of the Private Placement Warrants has been estimated using a Monte Carlo simulation model each measurement date. For the three months and nine months ended September 30, 2021, the Company recognized a gain resulting from a decrease in the fair value of the derivative warrant liabilities of approximately $1.1 For the three and nine months ended September 30, 2020, the Company recognized a loss of approximately $2.3 million and approximately $5.2 The estimated fair value of the Private Placement Warrants is determined using Level 3 inputs. Inherent in a Monte Carlo simulation are assumptions related to expected stock-price volatility, expected life, risk-free interest rate and dividend yield. The Company estimates the volatility of its common stock based on historical volatility of select peer companies that matches the expected remaining life of the warrants. The risk-free interest rate is based on the U.S. Treasury zero-coupon yield curve on the grant date for a 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 remaining at zero.

The fair value of Public Warrants issued in connection with the Initial Public Offering have been measured based on the listed market price of such warrants, a Level 1 measurement, beginning in June 2020. The estimated fair value of the Private Placement Warrants, and the Public Warrants prior to being separately listed and traded, is determined using Level 3 inputs. Inherent in a Monte Carlo simulation are assumptions related to expected stock-price volatility, expected life, risk-free interest rate and dividend yield. The Company estimates the volatility of its Class A common stock warrants based on implied volatility from the Company’s traded warrants and from historical volatility of select peer company’s Class A common stock that matches the expected remaining life of the warrants. The risk-free interest rate is based on the U.S. Treasury zero-coupon yield curve on the grant date for a maturity similar to the expected remaining life of the warrants.

Long-term debt, net of unamortized debt issuance costs and current portion at September 30, 2021 and December 31, 2020 consists of the following: September 30, December 31, 2021 2020 Variable Rate Revolving Credit Facility Term Loan, interest at LIBOR plus applicable margin, due February 26, 2025 $ 5,125,000 $ 7,218,750 Less: Unamortized debt issuance costs 229,725 282,512 Current portion of term loan payable, net of debt issuance costs 4,895,275 375,000 Long-term debt, net of unamortized debt issuance costs and current portion $ — $ 6,561,238 On May 2, 2020, the Company entered into a Small Business Administration (“SBA”) loan with MUFG Union Bank, N.A. in the amount of $2,992,758, with interest bearing at 1%. The maturity date of the loan is May 2, 2022. On May 13, 2020, the Company entered into a Paycheck Protection Program (“PPP”) loan with Celtic Bank Corporation in the amount of $2,000,000, with interest bearing at 1%. The maturity date of the loan is May 13, 2022. The Company recorded a PPP loan as a result of the acquisition of TOI FL on February 12, 2021 with Valley National Bank in the amount of $149,398, with interest bearing at 1%. The maturity date of the loan is May 4, 2022. The application for the PPP and SBA funds required the Company to, in good faith, certify that the current economic uncertainty made the loan request necessary to support the ongoing operations of the Company. This certification further required the Company to take into account its current business activity and its ability to access other sources of liquidity sufficient to support ongoing operations in a manner that is not significantly detrimental to the business. The receipt of these funds, and the forgiveness of the loan attendant to these funds, is dependent on the Company having initially qualified for the loan and qualifying for the forgiveness of such loan based on its future adherence to the forgiveness criteria. Management has performed an assessment and concluded they met the eligibility requirements to participate in the PPP and SBA programs and it is probable they will qualify for forgiveness, as determined by the program administrators within the parameters of the program. The loan proceeds were used to pay for qualifying salaries and were recognized to other revenues in 2020 as qualified expenses were paid. The Company applied for loan forgiveness in December 2020 for the PPP loan and in March 2021 for the SBA loan. Through the TOI FL acquisition, the Company recorded a PPP loan (and corresponding escrow receivable) for which the application for forgiveness was being processed. During the nine months ended September 30, 2021, the Company received notice of forgiveness for each of the PPP and SBA loans. Upon receiving forgiveness, the Company recognized the loan principal balance and accrued interest as a gain on debt extinguishment, with a corresponding write off of the escrow receivable, in the condensed consolidated statements of operation during the nine months ended September 30, 2021. On February 26, 2020 the Company entered into a credit agreement with MUFG Union Bank (“Credit Agreement”), which allows the Company to borrow up to an aggregate principal amount of $10,000,000 in the form of term loans, revolving credit commitments (“Revolver”), and a letter of credit (“LOC”) facility. The term loans and the Revolver shall bear interest at base rate plus the applicable margin or LIBOR rate plus the applicable margin. The Company can prepay the obligations at their option or upon the occurrence of certain events. The outstanding principal on the term loans will be repaid in quarterly installments equal to (i) $93,750 on the last business day of each quarter ending December 31, 2023, commencing on June 30, 2020 and (ii) $187,500 on the last business day of each quarter thereafter. The maturity date of the Credit Agreement is February 26, 2025. As of September 30, 2021, the Company has borrowed $5,125,000 in the form of a term loan. The Company paid down $2,500,000 drawn upon the Revolver in the second quarter, and no additional amounts were drawn during the current quarter. As of March 31, 2021 and December 31, 2020, the Company violated certain covenants in the Credit Agreement. On June 18, 2021, the Company entered into an amendment to the Credit Agreement, which reduced the aggregate principal amount from which the Company can borrow to $9,000,000 and concurrently provided a waiver for the covenant violations. As part of the amendment, the Company paid $2,000,000 of the outstanding principal balance on the term loan and no additional principal payments are required until the quarter ending March 31, 2022. The Company determined that the amendment to the Credit Agreement meet the definition of a debt modification under ASC 470-50, Modifications and Extinguishments Net debt issuance costs are presented as a direct reduction in the condensed consolidated balance sheets and amount to $229,725 from current debt and $282,512 from long-term debt as of September 30, 2021 and December 31, 2020, respectively. The amortization of the debt issuance costs was charged to interest expense for all periods presented. The amount of debt issuance costs included in interest expense for the nine months ended September 30, 2021 and September 30, 2020 was approximately $52,787 and $41,950, respectively. The Company paid interest of $193,096 and $168,530 on the Credit Agreement term loan for the nine months ended September 30, 2021 and 2020, respectively.	Note 11. Debt Short-term debt and current portion of long-term debt at December 31, 2020 and 2019 consists of the following: December 31, December 31, 2020 2019 1% Paycheck Protection Program Loan, due May 13, 2022 $ 2,000,000 $ — 1% Small Business Administration Loan, due May 2, 2022 2,992,758 — Current portion of term loan payable 375,000 — Short-term debt and current portion of long-term debt $ 5,367,758 $ — The Company accounts for long-term debt net of debt issuance costs.

The maturity date of the loan is May 2, 2022. On May 13, 2020, the Company entered into a Paycheck Protection Program (“PPP”) loan with Celtic Bank Corporation in the amount of $2,000,000, with interest bearing at 1%. The maturity date of the loan is May 13, 2022. The Company has classified the PPP and SBA loans above entirely as current liabilities as the majority of payments will occur throughout 2021. The application for the PPP and SBA funds required the Company to, in good faith, certify that the current economic uncertainty made the loan request necessary to support the ongoing operations of the Company. This certification further required the Company to take into account its current business activity and its ability to access other sources of liquidity sufficient to support ongoing operations in a manner that is not significantly detrimental to the business. The receipt of these funds, and the forgiveness of the loan attendant to these funds, is dependent on the Company having initially qualified for the loan and qualifying for the forgiveness of such loan based on its future adherence to the forgiveness criteria.Management has performed an assessment and concluded they met the eligibility requirements to participate in the PPP and SBA programs and it is probable they will qualify for forgiveness, as determined by the program administrators within the parameters of the program. The loan proceeds were used to pay for qualifying salaries in 2020 as qualified expenses were paid. The Company applied for forgiveness in December 2020 for the PPP loan and in March 2021 for the SBA loan; however, the Company’s eligibility and qualified expenses are subject to audit by the SBA and although the Company anticipates it will qualify for forgiveness, the SBA may require the Company to repay all or a portion of the loan value recorded for the year ended December 31, 2020. While the Company believes that the PPP loan was properly obtained, there can be no assurance regarding the outcome of an SBA review. The Company applied for loan forgiveness in December 2020 for the PPP loan. On June 17, 2021, the Company received notice of forgiveness of the loan. On February 26, 2020 the Company entered into a credit agreement with MUFG Union Bank (“Credit Agreement”), which allows the Company to borrow up to an aggregate principal amount of $10 million in the form of term loans, revolving credit commitments (“Revolver”), and a letter of credit (“LOC”) facility. The term loans and the Revolver shall bear interest at base rate plus the applicable margin or LIBOR rate plus the applicable margin. The Company can prepay the obligations at their option or upon the occurrence of certain events. The outstanding principal on the term loans will be repaid in quarterly installments equal to (i) $93,750 on the last business day of each quarter ending December 31, 2023, commencing on June 30, 2020 and (ii) $187,500 on the last business day of each quarter thereafter. The maturity date of the Credit Agreement is February 26, 2025. As of December 31, 2020, the Company has borrowed $7,500,000 in the form of a term loan from the $10,000,000 availability of the Credit Agreement, leaving $2,500,000 available borrowings under the Credit Agreement. The Company violated the senior leverage ratio and fixed charge coverage ratio associated with the Credit Agreement’s variable rate term loan in 2020 and during 2021. On June 18, 2021, the Company entered into an amendment to the Credit Agreement which changed the covenants and concurrently received a waiver for the period ended December 31, 2020. Net debt issuance costs are presented as a direct reduction of the Company’s long-term debt in the consolidated balance sheets and amount to $282,512 and $0 as of December 31, 2020 and 2019, respectively. The amortization of the debt issuance costs was charged to interest expense for all periods presented. The amount of debt issuance costs included in interest expense for the years ended December 31, 2020 and 2019 was approximately $59,988 and $0, respectively. The aggregate maturities of long-term debt for each of the five years subsequent to December 31, 2020 are: $375,000 in 2021, 2022 , and 2023 , $750,000 in 2024, and $5,343,750 in 2025. The Company paid interest of $226,764 on the Credit Agreement term loan for the year ended December 31, 2020.

Income Taxes
Income Taxes		Note 11 — Income Taxes The Company’s taxable income primarily consists of interest income on the Trust Account, less any franchise taxes. The Company’s formation and operating costs are generally considered start-up costs and are not currently deductible. The income tax provision (benefit) for the year ended December 31, 2020 consists of the following: December 31, 2020 December 31, 2019 Current Federal $ 11,434 $ — State — — Deferred Federal (101,676) (483) State — — Valuation allowance 101,676 483 Income tax provision 11,434 — The provision for income taxes was deemed to be de minimis for the period from November 1, 2019 (inception) through December 31, 2019. The Company’s net deferred tax assets are as follows: December 31, 2020 December 31, 2019 Deferred tax assets: Start-up/Organization costs $ 101,676 $ 315 Net operating loss carryforwards — 168 Total deferred tax assets 101,676 483 Valuation allowance (101,676) (483) Deferred tax asset, net of allowance $ — $ — In assessing the realization of deferred tax assets, management considers whether it is more likely than not that some portion or all of the deferred tax assets will not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which temporary differences representing net future deductible amounts become deductible. Management considers the scheduled reversal of deferred tax assets, projected future taxable income and tax planning strategies in making this assessment. After consideration of all of the information available, management believes that significant uncertainty exists with respect to future realization of the deferred tax assets and has therefore established a full valuation allowance. For the year ended December 31, 2020 and for the period from November 1, 2019 (inception) to December 31, 2019, the valuation allowance was $101,676 $483 A reconciliation of the statutory federal income tax rate (benefit) to the Company’s effective tax rate is as follows: December 31, 2020 December 31, 2019 Statutory federal income tax $ (1,748,979) $ (483) Change in fair value of derivative warrant liabilities (1,450,150) — Financing costs - derivative warrant liabilities (2,503) — Change in valuation allowance 3,213,066 483 Income tax expense $ 11,434 $ — There were no unrecognized tax benefits as of December 31, 2020, and 2019. No amounts were accrued for the payment of interest and penalties as of December 31, 2020, and 2019. 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. The Company’s management does not expect that the total amount of unrecognized tax benefits will materially change over the next twelve months.
TOI Parent Inc.
Income Taxes
Income Taxes	Note 12. Income Taxes The Company recorded income tax expense of $798,504 for the three months ended September 30, 2021, as compared to income tax benefit of $23,190 for the three months ended September 30, 2020. The increase of $821,694 in income tax expense is primarily related to the corresponding increase in our profitable entity’s, TOI Parent’s, pre-tax book income combined with an increase in our annual effective tax rate. Our effective tax rate decreased to (36.6)% for the three months ended September 30, 2021, from 3.3% for the three months ended September 30, 2020, primarily due to increase in the valuation allowance, partially offset by the tax effect of gain on PPP loan forgiveness, which is not taxable for federal income tax purposes. The Company recorded income tax expense of $1,796,123 for the nine months ended September 30, 2021, as compared to income tax benefit of $298,102 for the nine months ended September 30, 2020. The increase of $2,094,225 in income tax expense is primarily related to the corresponding increase in our profitable entity’s, TOI Parent’s, pre-tax book income combined with an increase in our effective tax rate. Our effective tax rate increased to 175.2% for the nine months ended September 30, 2021, from 3.3% for the nine months ended September 30, 2020, primarily due to increase in the valuation allowance, partially offset by the tax effect of gain on PPP loan forgiveness, which is not taxable for federal income tax purposes. Our effective tax rate for the three and nine months ended September 30, 2021, was different than the U.S. federal statutory tax rate of 21.0% primarily due to increase in the valuation allowance, partially offset by the tax effect of gain on PPP loan forgiveness, which is not taxable for federal income tax purposes.	Note 12. Income Taxes The components of the provision (benefit) for income taxes consists of: Current Deferred Total Year ended December 31, 2020: U.S. federal $ 822,490 $ (919,164) $ (96,674) State and local 28,183 (424,332) (396,149) $ 850,673 $ (1,343,496) $ (492,823) Current Deferred Total Year ended December 31, 2019: U.S. federal $ 355,245 $ 697,261 $ 1,052,506 State and local 203,261 127,501 330,762 $ 558,506 $ 824,762 $ 1,383,268 Current Deferred Total Period from September 20, 2018 through December 31, 2018: U.S. federal $ — $ 552,044 $ 552,044 State and local 91,039 179,057 270,096 $ 91,039 $ 731,101 $ 822,140 Current Deferred Total Period from January 1, 2018 through September 19, 2018: U.S. federal $ — $ — $ — State and local 132,942 (42,337) 90,605 $ 132,942 $ (42,337) $ 90,605 The Company’s income tax expense differs from the amount that would have resulted from applying the federal statutory rate of 21% to pretax from Period from Period from September 20, January 1, 2018 2018 Year Ended Year Ended through through December 31, December 31, December 31, September 19, 2020 2019 2018 2018 Income tax at federal statutory rate $ (3,110,753) $ (554,131) $ (246,014) $ 1,266,764 Income not subject to corporate level tax — — (30,292) (1,266,764) State tax, net federal benefit (982,329) (69,370) 238,489 90,605 Fines and Penalties — — — — Transaction costs — — 668,779 — Adjustment to deferred taxes — 138,648 — — Change in tax status — — 187,779 — Income Tax Payable: Change in valuation allowance 3,596,998 1,854,006 — — Other 3,261 14,115 3,399 — Income tax (benefit) expense $ (492,823) $ 1,383,268 $ 822,140 $ 90,605 The tax effects of temporary differences that give rise to significant portions of the deferred tax assets and deferred tax liabilities at December 31, 2020 and 2019 are presented below.

The net change in the total valuation allowance was an increase of $3,596,998 in 2020 and an increase of $1,854,005 in 2019. The valuation allowance at December 31, 2020, was primarily related to net operating loss carryforwards of the Practice that, in the judgment of management, are not more likely than not to be realized. TOI Parent and the Practice file separate federal and state tax returns. Accordingly, net operating losses of the Practice cannot offset taxable income of TOI Parent. Deferred tax assets and deferred tax liabilities have been separately determined for TOI Parent and the Practice, as has the valuation allowance assessment for each. The table above reflects the combined deferred tax assets, deferred tax liabilities, and valuation allowance for both TOI Parent and the Practice. Of the $(5,451,003) total valuation allowance, $(4,801,222) is attributable to the Practice and $(649,781) is attributable to TOI Parent. The net deferred tax liabilities of $(1,612,769) is primarily attributable to TOI Parent, which is net of a $(649,781) valuation allowance. The Practice has total gross deferred tax assets of $4,922,056, most of which is reduced by a valuation allowance. In assessing the realizability of deferred tax assets, management considers whether it is more likely than not that some portion or all of the deferred tax assets will not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences become deductible. Management considers the scheduled reversal of deferred tax liabilities (including the effect of available carry back and carryforward periods), projected future taxable income, and tax-planning strategies in making this assessment. Based upon the level of historical taxable income and projections for future taxable income over the periods in which the deferred tax assets are deductible, management believes it is more likely than not that the Company will realize the benefits of these deductible differences, net of the existing valuation allowances at December 31, 2020. The amount of the deferred tax asset considered realizable, however, could be reduced in the near term if estimates of future taxable income during the carryforward period are reduced. At December 31, 2020, the Company has net operating loss carryforwards for Federal income tax purposes of $7,637,918, all attributable to the Practice, which are available to offset future Federal taxable income of the Practice indefinitely. The Company has net operating loss carryforwards for state income tax purposes of $8,424,443, most of which is attributable to the Practice, which will begin to expire after 2041. Pursuant to Internal Revenue Code Section 382, annual use of the Company’s net operating loss (“NOL”) carryforwards may be limited in the event a cumulative change in ownership of more than 50% occurs within a three-year period. The Company has not completed a Section 382 analysis, however, it is not aware of any transactions that would result in an ownership change under Section 382. Further, the Company’s direct shareholders have remained constant since its inception in 2018. A summary of the changes in the amount of unrecognized tax benefits (excluding interest and penalties) for 2020 and 2019 is as follows: December 31, December 31, 2020 2019 Beginning balance of unrecognized tax benefits $ 1,902,659 $ — Additions based on tax positions related to the current year — 1,902,659 Additions based on tax positions of prior years — — Reductions due to lapse of applicable statute of limitation — — Settlements — — Ending balance of unrecognized tax benefits $ 1,902,659 $ 1,902,659 The Company anticipates reversal of the above amount within the next 12 months upon amendment of the Company’s 2019 federal and state income tax returns. The Company recognizes interest and penalties related to unrecognized tax benefits in income tax expense. Due to the Company’s NOL position, no interest or penalties have been recognized with respect to unrecognized tax benefits, as such amounts are considered immaterial. The Company is subject to taxation in the U.S., California, and Arizona. As of December 31, 2020, the statute of limitations remains open for tax year 2018, 2019, and 2020. The Company has accounted for the changes in net operating loss carryovers as a result of the CARES Act. Other provisions of the CARES Act did not have a material impact on the Company’s financial statements as of December 31, 2020.

Common and Preferred Shares The Company issued Series A Preferred Shares under the Company’s original Certificate of Incorporation dated September 10, 2018 and the Company’s Shareholders’ Agreement dated September 19, 2018. The Certificate of Incorporation was amended and restated on September 14, 2018 (“Amendment I”) and again on November 6, 2020 (“Amendment II”). Per the original Certificate of Incorporation, the Company had authority to issue 30,000 shares, consisting of 20,000 common shares and 10,000 Series A Preferred Shares. The Company issued 10,000 shares of Series A Preferred Shares on September 10, 2018 at $0.001 par value per share. As a result of Amendment I to the Certificate of Incorporation, Series A Preferred shareholders were entitled to a return of capital on their shares prior to any declaration or payment of dividends to common shareholders. The original preferred return was equal to the number of shares held by the preferred shareholder multiplied by the price paid for such shares. In the event of liquidation, dissolution, or winding up of the operations of the Company, Series A Preferred shareholders had preferential liquidation rights compared to the common shareholders. As such, the preferred shareholders were entitled to full payment of the original preferred return before the remaining assets of the Company were to be distributed to common and preferred shareholders based on their pro-rata share of total outstanding securities. Holders of Series A Preferred Shares were granted one vote, per share, for all matters voted on by the common shareholders of the Company. Given the short duration and immaterial operations of the Company between the execution of Amendment I as compared to the Original Certificate of Incorporation, there was no material accounting impact to the Company’s financial statements resulting from the execution of Amendment I. As a result of Amendment II, the Company now has the authority to issue 420,000 shares consisting of 400,000 common shares and 20,000 Series A Preferred Shares. Additionally, each outstanding common share was split into 10 common shares. Amendment II resulted in an extinguishment of old Series A Preferred Shares under the original Certificate of Incorporation and a deemed authorization and issuance of new Series A Preferred Shares. As such, the Company recognized Series A Preferred Shares at fair value at the amendment date, with the difference between the fair value and carrying value being recognized in retained earnings. The fair value of the Series A Preferred Shares was derived using a combination of a an option pricing model (“OPM”) and common stock equivalent method (“CSE”) which are considered Level 2 and Level 3 inputs, respectively, in the fair value hierarchy. The assumptions used in the OPM and CSE models are provided in the following tables: Option-pricing method Valuation date 11/6/2020 Liquidity event date 12/31/2024 Time to liquidity 4.15 years Total equity value $ 82,000,000 Annual dividend rate for common stock 0.0 % Annualized volatility 40.0 % Risk-free rate (continuously compounding) 0.3 % Common-stock equivalent method Valuation date 11/6/2020 Liquidity event date 12/31/2024 Time to liquidity 4.15 years Total equity value $ 82,000,000 Value per common stock equivalent $ 562.06 Further, under Amendment II, cumulative dividends on Series A Preferred Shares will accrue, whether or not declared by the Board at a rate of 6% per year. The preferred shareholders are entitled to payment of all accrued but unpaid dividends prior to declaration or payment of dividends to common shareholders. As of September 30, 2021 and December 31, 2020, dividends in arrears were $9,547,569 and $6,883,835, respectively. In the event of liquidation, Series A Preferred shareholders are entitled to receive payment of assets before distribution to common shareholders. If the full preferential amount is unavailable, the Series A Preferred shareholders will share ratably in the distribution. Additionally, holders of Series A Preferred Shares now have 10 votes, per share, as of November 6, 2020, for all matters voted upon by the common shareholders of the Company and have the option to convert outstanding Series A Preferred Shares into common shares, at any point in time, by a factor of 1 The Series A Preferred shareholders control the vote of the Board through direct representation and can initiate a sale of the Company that may result in the Series A Preferred Shares being redeemed for cash. This potential event is deemed to be outside the control of the Company and therefore, the Series A Preferred Shares are accounted for as temporary equity. In the first quarter of 2021, TOI Parent executed an equity capital raise in separate transactions with 3 accredited investors. A total of 1,451 of the Company’s Series A Preferred Shares were purchased in exchange for $20,000,000 and are subject to the terms of Amendment II of the Certificate of Incorporation. There were 11,451 Series A Preferred Shares issued and outstanding outstanding	Note 13. Common and Preferred Shares The Company issued Series A Preferred Shares under the Company’s original Certificate of Incorporation dated September 10, 2018 and the Company’s Shareholders’ Agreement dated September 19, 2018. The Certificate of Incorporation was amended and restated on September 14, 2018 (“Amendment I”) and again on November 6, 2020 (“Amendment II”). Per the original Certificate of Incorporation, the Company had authority to issue 30,000 shares, consisting of 20,000 common shares and 10,000 Series A Preferred Shares. The Company issued 10,000 shares of Series A Preferred Shares on September 10, 2018 at $0.001 par value per share. There were 10,000 Series A Preferred Shares issued and outstanding at December 31, 2020, 2019, and 2018. As a result of Amendment I to the Certificate of Incorporation, Series A Preferred shareholders were entitled to a return of capital on their shares prior to any declaration or payment of dividends to common shareholders. The original preferred return was equal to the number of shares held by the preferred shareholder multiplied by the price paid for such shares. In the event of liquidation, dissolution, or winding up of the operations of the Company, Series A Preferred shareholders had preferential liquidation rights compared to the common shareholders.

As a result of Amendment II, the Company has the authority to issue 420,000 shares consisting of 400,000 common shares and 20,000 Series A Preferred Shares. Additionally, each outstanding common share was split into 10 common shares. Amendment II resulted in the addition of a conversion option which allows the preferred shareholders to convert the Series A Preferred Shares into common shares. In addition, under Amendment II, the preferred shareholders are entitled to 6% cumulative dividends. Therefore, Amendment II resulted in an extinguishment of old Series A Preferred Shares under the original Certificate of Incorporation and a deemed authorization and issuance of new Series A Preferred Shares. As such, the Company recognized Series A Preferred Shares at fair value at the amendment date, with the difference between the fair value and carrying value being recognized in retained earnings.

The preferred shareholders are entitled to payment of all accrued but unpaid dividends prior to declaration or payment of dividends to common shareholders. As dividends have not been declared no liability associated with the accrued dividends has been recognized by the Company. As of December 31, 2020, dividends in arrears were $6,883,835. In the event of liquidation, Series A Preferred shareholders are entitled to receive payment of assets before distribution to common shareholders. If the full preferential amount is unavailable, the Series A Preferred shareholders will share ratably in the distribution. Additionally, holders of Series A Preferred Shares now have 10 votes, per share, for all matters voted upon by the common shareholders of the Company and have the option to convert outstanding Series A Preferred Shares into common shares, at any point in time, by a factor of 1 -to-10. The Series A Preferred shareholders control the vote of the Board through direct representation and can initiate a sale of the Company that may result in the Series A Preferred Shares being redeemed for cash. This potential event is deemed to be outside the control of the Company and therefore, the Series A Preferred Shares are accounted for as temporary equity. As of December 31, 2020, there were 100 common shares outstanding as one option holder of the Company’s 2019 Non-Qualified Stock Option Plan exercised their option to purchase the Company’s common shares on September 12, 2020. The Company had no outstanding common shares as of December 31, 2019, and 2018. The Practice, the Predecessor entity, had 1,000 common shares outstanding as of September 19, 2018.

Share-based Compensation Arrangement by Share-based Payment Award
Share-Based Compensation	Note 14. Share-Based Compensation Non-Qualified Stock Option Plan On January 2, 2019, the Company issued and adopted the 2019 Non-Qualified Stock Option Plan (“the Plan”) to incentivize directors, consultants, advisors, and other key employees of the Company and its subsidiaries to continue their association by providing opportunities to participate in the ownership and further growth of the Company. The Plan provides for the grant of options (“the Stock Options”) to acquire common shares of the Company. The Company issued immaterial amounts of stock options to non-employees for the nine months ended September 30, 2021 and the year ended December 31, 2020. Stock Options are exercised from the pool of shares designated by the appropriate Committee of the Board of Directors. The grant-date fair value of each option award is estimated on the date of grant using the Black-Scholes-Merton option-pricing model. The grant date fair value of the service vesting and the performance vesting options is recognized as an expense over the requisite service period and upon the achievement of the performance condition deemed probable of being achieved, respectively. The exercise price of each Stock Option shall be determined by the Committee and may not be less than the fair market value of the common shares on the date of grant. Stock Options have 10-year terms, after which they expire and are no longer exercisable. The total number of common shares for which Stock Options may be granted under the Plan shall not exceed 13,640. The Plan was amended on November 6, 2020, pursuant to which the total number of common shares for which Stock Options may be granted under the Plan shall not exceed 15,640. At September 30, 2021, there were 399,900 common shares of the Company authorized and unissued. The weighted average assumptions used in the Black-Scholes-Merton option-pricing model for the 2021 Stock Options are provided in the following table: 9 Months Ended 09/30/2021 Valuation assumptions Expected dividend yield — % Expected volatility 38.6% and 40.2 % Risk-free interest rate 0.76% to 1.12 % Expected term (years) 7 Stock option activity during the periods indicated is as follows: Weighted Weighted average Aggregate Number average remaining intrinsic Stock options of shares exercise price contractual term value Balance at January 1, 2021 14,860 $ 497.95 Granted 2,023 630.00 Exercised — Forfeited (1,215) 504.38 Expired — Balance at September 30, 2021 15,668 514.50 8.31 — Vested options exercisable at September 30, 2021 2,578 $ 497.03 6.86 — In June, 2021 the Company and certain participants in the Plan entered into agreements to amend the terms of the Stock Options previously issued to the participant during Q1 and Q2 2021. The amendment primarily related to updating the exercise price, vesting conditions, and the number of Stock Options. The modification to the Stock Options resulted in immaterial incremental share-based compensation expense recorded in the Company’s statement of operations. Total share-based compensation expense for the nine months ended September 30, 2021 and September 30, 2020 was $152,617 and $112,669, respectively, and for the three months ended September 30, 2021 and September 30, 2020, share-based compensation expense was $59,678 and $36,343, respectively. At September 30, 2021 and September 30, 2020, there was $604,655 and $384,434, respectively, of total unrecognized compensation cost related to unvested service Stock Options granted under the Plan that are expected to vest. That cost is expected to be recognized over a weighted average period of 2.68 and 3.07 years for the 2021 and 2020 unrecognized compensation costs, respectively. At September 30, 2021 and September 30, 2020, there was $1,294,168 and $807,777, respectively, of unrecognized stock compensation related to the unvested performance Stock Options granted under the Plan that are expected to vest. The total fair value of common shares vested for the nine months ended September 30, 2021 and September 30, 2020 was $321,591 and $220,518, respectively, and for the three months ended September 30, 2021 and September 30, 2020, the fair value of common shares vested was $84,813 and $38,759, respectively. Restricted Stock Awards (“RSAs”) Additionally, Agajanian Holdings (“Holdings”), a holder of Series A Preferred Shares of the Company, enters into arrangements with physicians employed by TOI CA to issue RSAs which represent Series A Preferred Shares of the Company. The RSAs only have performance vesting requirements linked to the sale of the Company so long as the optionee remains continuously and actively employed by the Company’s subsidiaries through the vesting date. For the nine months ended September 30, 2021 and the year ended December 31, 2020, Holdings issued 0 and 188 RSAs, respectively. The optionee is not entitled to dividends or distributions from the Company, nor are they entitled to vote. Additionally, the RSA may not be sold, transferred, pledged, or assigned at any time. No RSAs were issued for the nine months ended September 30, 2021 and the year ended December 31, 2020. A summary of the activity for the RSAs for the nine months ended September 30, 2021 is shown in the following table: Number of shares Balance at January 1, 2021 238 Granted — Forfeited (4) Balance at September 30, 2021 234 For the nine months ended September 30, 2021 and September 30, 2020, no compensation costs were recognized related to the RSAs. At September 30, 2021 and September 30, 2020, there was no unrecognized compensation expense related to the RSAs that are expected to vest.	Note 14. Share-Based Compensation Non-Qualified Stock Option Plan On January 2, 2019, the Company issued and adopted the 2019 Non-Qualified Stock Option Plan (the “Plan”) to incentivize directors, consultants, advisors, and other key employees of the Company and its subsidiaries to continue their association by providing opportunities to participate in the ownership and further growth of the Company. The Plan provides for the grant of options (the “Stock Options”) to acquire common shares of the Company. The Company issued immaterial amounts of stock options to non- employees for the years ended December 31, 2020 and 2019. Stock Options are exercised from the pool of shares designated by the appropriate Committee of the Board of Directors. The grant-date fair value of each option award is estimated on the date of grant using the Black-Scholes-Merton option-pricing model. The grant date fair value of the service vesting and the performance vesting options is recognized as an expense over the requisite service period and upon the achievement of the performance condition deemed probable of being achieved, respectively. The exercise price of each Stock Option shall be determined by the Committee and may not be less than the fair market value of the common shares on the date of grant. Stock Options have 7-year terms, after which they expire and are no longer exercisable. The total number of common shares for which Stock Options may be granted under the Plan shall not exceed 13,640. The Plan was amended on November 6, 2020, pursuant to which the total number of common shares for which Stock Options may be granted under the Plan shall not exceed 15,640. At December 31, 2020 and 2019, there were 399,900 and 400,000, respectively, common shares of the Company authorized and unissued. Stock Options become vested upon fulfillment of either service vesting conditions, performance vesting conditions, or both, as determined by the award agreement entered into by the Company and optionee. The service vesting requirement states that: (i) 25% of the service vesting options shall vest on the first anniversary of the grant date and (ii) the remaining 75% shall vest on an equal monthly-basis, so long as the optionee has remained continuously employed by the Company from the date of the award through the fourth anniversary of the grant date. The performance vesting requirement states that Stock Options shall vest upon sale of the Company only if the optionee has been continuously employed by the Company or its subsidiaries from the grant date through the date of such sale of the Company. For the awards vesting based on service conditions only and that have a graded vesting schedule, the Company recognizes compensation expense for vested awards in earnings, net of actual forfeitures in the period they occur, on a straight-line basis over the requisite service period. The weighted average assumptions used in the Black-Scholes-Merton option-pricing model for the 2020 and 2019 Stock Options are provided in the following table: 2020 2019 Valuation assumptions Expected dividend yield — % — % Expected volatility 35.00% to 40.20 % 54.30 % Risk-free interest rate 0.51% to 2.62 % 1.60% to 2.62 % Expected term (years) 7 7 Stock option activity during the periods indicated is as follows: Weighted Weighted average Number of average exercise remaining Aggregate Stock options shares price contractual term intrinsic value Balance at January 1, 2020 9,965.00 $ 496.10 Granted 7,170.00 499.94 Exercised (100.00) 496.10 Forfeited (2,175.00) 496.10 Expired — — Balance at December 31, 2020 14,860.00 $ 497.95 8.94 $ — Vested Options Exercisable at December 31, 2020 1,270.00 $ 496.10 8.25 $ — Weighted Weighted average Number of average exercise remaining Aggregate Stock options shares price contractual term intrinsic value Balance at January 1,2019 — $ — Granted 13,945.00 496.10 Exercised — — Forfeited (3,980.00) 496.10 Expired — — Balance at December 31, 2019 9,965.00 $ 496.10 9.39 $ — Vested Options Exercisable at December 31, 2019 318.75 $ 496.10 8.70 $ — Total share-based compensation expense during the years ended December 31, 2020 and 2019 was $150,796 and $94,007, respectively. At December 31, 2020 and 2019, there was $492,014 and $506,688, respectively, of total unrecognized compensation cost related to unvested service Stock Options granted under the Plan that are expected to vest. That cost is expected to be recognized over a weighted average period of 3.05 and 3.38 years for the 2020 and 2019 unrecognized compensation costs, respectively.

TOI Parent Inc.
Commitments and Contingencies
Commitments and Contingencies	Note 15. Commitments and Contingencies The Company evaluates contingencies based upon available evidence. In addition, allowances for losses are provided each year for disputed items which have continuing significance. The Company believes that allowances for losses have been provided to the extent necessary, and that its assessment of contingencies is reasonable. Due to the inherent uncertainties and subjectivity involved in accounting for contingencies, there is at least a reasonable possibility that recorded estimates will change by a material amount in the near term. To the extent that the resolution of contingencies results in amounts which vary from management’s estimates, future operating results will be charged or credited. The principal commitments and contingencies are described below. Leases The Company leases its offices, clinics and certain equipment under non-cancellable operating leases, and certain equipment under capital lease agreements, that expire at various dates through 2028. The Company has 49 rental agreements for property. Additionally, the Company has 4 rental agreements for medical equipment classified as capital leases. Future minimum lease payments under noncancellable operating leases (with initial or remaining lease terms in excess of one year) and future minimum capital lease payments as of September 30, 2021 were: Capital Operating leases leases Year ending December 31: 2021 $ 8,572 $ 874,490 2022 36,736 3,430,762 2023 36,736 3,151,293 2024 30,614 2,673,093 2025 — 2,141,122 Thereafter — 1,674,718 Total minimum lease payments $ 112,658 $ 13,945,478 Less: amount representing interest (6% interest rate) (8,286) Present value of net minimum capital lease payments 104,372 Less current installments of obligations under capital leases (32,344) Obligations under capital leases, excluding current installments $ 72,028 Legal Matters The Company is subject to certain outside claims and litigation arising in the ordinary course of business. In the opinion of management, the outcome of such matters will not have a material effect on the Company’s condensed consolidated financial statements. Loss contingencies entail uncertainty and a possibility of loss to an entity. If the loss is probable and the amount of loss can be reasonably estimated, the loss should be accrued according to Accounting Standards Codification No. 450-20, Disclosure of Certain Loss Contingencies Indemnities The Company’s Articles of Incorporation and bylaws require it, among other things, to indemnify the director or officer against specified expenses and liabilities, such as attorneys’ fees, judgments, fines, and settlements, paid by the individual in connection with any action, suit, or proceeding arising out of the individual’s status or service as its director or officer, other than liabilities arising from willful misconduct or conduct that is knowingly fraudulent or deliberately dishonest, and to advance expenses incurred by the individual in connection with any proceeding against the individual with respect to which the individual may be entitled to indemnification by the Company. The Company also indemnifies its lessor in connection with its facility lease for certain claims arising from the use of the facilities. These indemnities do not provide for any limitation of the maximum potential future payments it could be obligated to make. Historically, the Company has not incurred any payments for these obligations and, therefore, no liabilities have been recorded for these indemnities in the accompanying condensed consolidated balance sheet. The Health Insurance Portability and Accountability Act The Health Insurance Portability and Accountability Act (“HIPAA”) assures health insurance portability, reduces healthcare fraud and abuse, guarantees security and privacy of health information, and enforces standards for health information. Organizations are required to be in compliance with HIPAA provisions. The Health Information Technology for Economic and Clinical Health Act (“HITECH”) imposes notification requirements in the event of certain security breaches relating to protected health information. Organizations are subject to significant fines and penalties if found not to be compliant with the provisions outlined in the regulations.The Company believes it is in compliance with these laws. Regulatory Matters Laws and regulations governing the Medicare program and healthcare generally, are complex and subject to interpretation. The Company believes that it is in compliance with all applicable laws and regulations and is not aware of any pending or threatened investigations involving allegations of potential wrongdoing. While no regulatory inquiries have been made, compliance with such laws and regulations can be subject to future government review and interpretation as well as significant regulatory action including fines, penalties, and exclusion from the Medicare and Medi-Cal programs. Many of the Company’s payor and provider contracts are complex in nature and may be subject to differing interpretations regarding amounts due for the provision of medical services. Such differing interpretations may not come to light until a substantial period of time has passed following contract implementation. Liabilities for claims disputes are recorded when the loss is probable and can be estimated. Any adjustments to reserves are reflected in current operations. The Company does not have any reserves for regulatory matters as of September 30, 2021 and December 31, 2020. Liability Insurance The Company believes that its insurance coverage is appropriate based upon the Company’s claims experience and the nature and risks of the Company’s business. In addition to the known incidents that have resulted in the assertion of claims, the Company cannot be certain that its insurance coverage will be adequate to cover liabilities, arising out of claims asserted against the Company or the Company’s affiliated professional organizations, in the future where the outcomes of such claims are unfavorable. The Company believes that the ultimate resolution of all pending claims, including liabilities in excess of the Company’s insurance coverage, will not have a material adverse effect on the Company’s financial position, results of operations or cash flows; however, there can be no assurance that future claims will not have such a material adverse effect on the Company’s business. Contracted physicians are required to obtain their own insurance coverage.	Note 15. Commitments and Contingencies The Company evaluates contingencies based upon available evidence. In addition, allowances for losses are provided each year for disputed items which have continuing significance. The Company believes that allowances for losses have been provided to the extent necessary, and that its assessment of contingencies is reasonable. Due to the inherent uncertainties and subjectivity involved in accounting for contingencies, there is at least a reasonable possibility that recorded estimates will change by a material amount in the near term. To the extent that the resolution of contingencies results in amounts which vary from management’s estimates, future operating results will be charged or credited. The principal commitments and contingencies are described below. Leases The Company leases its offices, clinics and certain equipment under non-cancellable operating leases, and certain equipment under capital lease agreements, that expire at various dates through 2027. The Company has 43 rental agreements for property. Additionally, the Company has 4 rental agreements for medical equipment classified as capital leases. Future minimum lease payments under noncancellable operating leases (with initial or remaining lease terms in excess of one year) and future minimum capital lease payments as of December 31, 2020 were: Capital Operating leases leases Year ending December 31: 2021 $ 36,736 $ 3,095,533 2022 36,736 2,831,516 2023 36,736 2,559,759 2024 30,614 2,060,385 2025 — 1,510,935 Thereafter — 793,363 Total minimum lease payments $ 140,822 $ 12,851,491 Less: amount representing interest (6% interest rate) (12,587) Present value of net minimum capital lease payments 128,235 Less current installments of obligations under capital leases (31,191) Obligations under capital leases, excluding current installments $ 97,044 Legal Matters The Company is subject to certain outside claims and litigation arising in the ordinary course of business. In the opinion of Management, the outcome of such matters will not have a material effect on the Company’s consolidated financial statements. Loss contingencies entail uncertainty and a possibility of loss to an entity. If the loss is probable and the amount of loss can be reasonably estimated, the loss should be accrued according to ASC 450-20. As of the end of December 31, 2020, the Company accrued a loss contingency for a legal matter related to an employee lawsuit, which was settled in 2021 for approximately$350,000. Indemnities The Company’s Articles of Incorporation and bylaws require it, among other things, to indemnify the director or officer against specified expenses and liabilities, such as attorneys’ fees, judgments, fines, and settlements, paid by the individual in connection with any action, suit, or proceeding arising out of the individual’s status or service as its director or officer, other than liabilities arising from willful misconduct or conduct that is knowingly fraudulent or deliberately dishonest, and to advance expenses incurred by the individual in connection with any proceeding against the individual with respect to which the individual may be entitled to indemnification by the Company. The Company also indemnifies its lessor in connection with its facility lease for certain claims arising from the use of the facilities. These indemnities do not provide for any limitation of the maximum potential future payments it could be obligated to make. Historically,the Company has not incurred any payments for these obligations and, therefore, no liabilities have been recorded for these indemnities in the accompanying consolidated balance sheets. The Health Insurance Portability and Accountability Act The Health Insurance Portability and Accountability Act (“HIPAA”) assures health insurance portability, reduces healthcare fraud and abuse, guarantees security and privacy of health information, and enforces standards for health information. Organizations are required to be in compliance with HIPAA provisions. The Health Information Technology for Economic and Clinical Health Act (“HITECH”) imposes notification requirements in the event of certain security breaches relating to protected health information. Organizations are subject to significant fines and penalties if found not to be compliant with the provisions outlined in the regulations. The Company believes it is in compliance with these laws. Regulatory Matters Laws and regulations governing the Medicare program and healthcare generally, are complex and subject to interpretation. The Company believes that it is in compliance with all applicable laws and regulations and is not aware of any pending or threatened investigations involving allegations of potential wrongdoing. While no regulatory inquiries have been made, compliance with such laws and regulations can be subject to future government review and interpretation as well as significant regulatory action including fines, penalties, and exclusion from the Medicare and Medi-Cal programs. Many of the Company’s payor and provider contracts are complex in nature and may be subject to differing interpretations regarding amounts due for the provision of medical services. Such differing interpretations may not come to light until a substantial period of time has passed following contract implementation. Liabilities for claims disputes are recorded when the loss is probable and can be estimated. Any adjustments to reserves are reflected in current operations. The Company does not have any reserves for regulatory matters as of December 31, 2020 and 2019. Liability Insurance The Company believes that its insurance coverage is appropriate based upon the Company’s claims experience and the nature and risks of the Company’s business. In addition to the known incidents that have resulted in the assertion of claims, the Company cannot be certain that its insurance coverage will be adequate to cover liabilities, arising out of claims asserted against the Company or the Company’s affiliated professional organizations, in the future where the outcomes of such claims are unfavorable. The Company believes that the ultimate resolution of all pending claims, including liabilities in excess of the Company’s insurance coverage, will not have a material adverse effect on the Company’s financial position, results of operations or cash flows; however, there can be no assurance that future claims will not have such a material adverse effect on the Company’s business. Contracted physicians are required to obtain their own insurance coverage.

TOI Parent Inc.
Business Combination
Business Combination	Note 16. Business Combination On February 12, 2021 (the “Acquisition Date”), the Company entered into an asset purchase agreement and master services agreement (PCC MSA) with Anil N Raiker, M.D., P.L.C., d/b/a Pinellas Cancer Center (“PCC”) and Anil Raiker, M.D., an individual. Pursuant to the asset purchase agreement, the Company purchased from PCC certain non-clinical assets, properties, and rights. Pursuant to the PCC MSA, TOI Management established an ongoing management services agreement which grants TOI Management the right to control the non-clinical and management operations of PCC. Anil Raiker, M.D. continued to own all of the issued and outstanding equity interests of PCC. Pursuant to the PCC MSA, and as further described in Note 17, TOI Management became PCC’s primary beneficiary and thus consolidated PCC and its subsidiaries. The consolidation of PCC (the “Acquisition”) at the Acquisition Date constituted a business combination in accordance with ASC 805. See Note 2 for a summary of the Company’s policies related to business combinations. The estimated fair value of the net assets acquired at the Acquisition Date amounted to $256,514. The total consideration for the Acquisition was $1,710,000, comprised of a cash payment of $892,500 and deferred consideration of $817,500. The deferred cash consideration is to be paid in two equal installments on the first and second anniversary of the transaction closing date (February 12, 2022 and 2023, respectively). Considering the Company’s incremental borrowing rate, the present value of the deferred cash consideration is not materially different than its stated value. The purchase consideration for the Acquisition has been allocated under the acquisition method of accounting to the estimated fair market value of the net assets acquired including a residual amount of tax deductible goodwill of approximately $1,453,486. The Acquisition was made primarily to expand the Company’s market share to the Florida market. The goodwill of $1,453,486 arising from the purchase is derived largely from the expected growth of the Company, as well as synergies and economies of scale expected from combining operations with the Company. The establishment of the allocation to goodwill requires the extensive use of accounting estimates and management judgement. The fair values assigned to the assets acquired are based on estimates and assumptions from data that is readily available. Consideration: Cash $ 892,500 Deferred consideration arrangement 817,500 Fair value of total consideration transferred 1,710,000 Estimated fair value of assets acquired and liabilities assumed: Cash 65,042 Accounts receivable 248,816 Inventory 62,656 Other receivables 149,398 Goodwill 1,453,486 Total assets acquired 1,979,398 Accounts payable 120,000 Debt, inclusive of PPP 149,398 Total liabilities assumed 269,398 Net assets acquired $ 1,710,000 Subsequent to the Acquisition, the Company filed an amendment to the articles of incorporation of PCC to legally change the name to The Oncology Institute FL, LLC (TOI FL). The change was solely nominal, and the legal form, tax attributes, and books and records of PCC all remained. The revenues, earnings, and pro forma effects of the Acquisition are not and	Note 16. Business Combination Business Combination Information During 2018, the Agajanian Family Trust, American Institute of Research, and Richy Agajanian Holdings, a Professional Corporation, founded TOI Management as a management services organization for provider organizations. On September 19, 2018 (the “Acquisition Date”), TOI Management acquired all the non-clinical assets of the Practice, ICRI, and HHHC in exchange for TOI Management’s equity (the “Non-Clinical Asset Purchase”). Concurrently on the Acquisition Date, TOI Management entered into a management services agreement (the “MSA”) with the Practice and its subsidiaries to provide comprehensive management and administrative services. Pursuant to the MSA, and as further described in Note 17, TOI Management became the Practice’s primary beneficiary and thus consolidated the Practice and its subsidiaries. The consolidation of the Practice (together with the Non-Clinical Asset Purchase, the “Acquisition”) at the Acquisition Date resulted in the fair valuation of the Practice’s net assets. Intangible assets identified included payor contracts, trade names, and clinical contracts, which were recorded at fair value. The remaining difference in net assets at fair value was allocated to goodwill. See Note 2 for a summary of the Company’s policies relating to business combinations. The total consideration transferred was $44,958,702, of which $34,875,000 was in cash and rollover units valued at $10,083,702. Acquisition and integration expenses paid the Company totaled $3,184,660 for the year ended December 31, 2018 and are included in the Successor financial statements in selling, general, and administrative expenses. The fair value of assets acquired and liabilities assumed as part of the Acquisition is summarized as follows: Fair value of assets acquired and liabilities assumed: Cash $ 505,317 Accounts receivable 11,097,858 Inventories 2,707,640 Prepaid expenses and other 144,447 Property and equipment, net 388,511 Goodwill 14,076,674 Intangible assets, net 25,234,000 Total assets acquired $ 54,154,447 Accounts payable $ 136,989 Accrued expenses and other current liabilities 7,658,103 Deferred tax liability 1,400,653 Total liabilities assumed $ 9,195,745 Net assets acquired $ 44,958,702 In determining the fair value of the intangible assets, the Company considered, among other factors, the best use of the acquired assets, analyses of historical financial performance of the services, and estimates of future performance of the products and intellectual properties acquired. The Company has recorded the purchase price of the identified intangible assets and is amortizing such values over their estimated useful life of 10 years. The goodwill of $14,076,674 arising from the purchase is derived largely from the expected growth of the Company, as well as synergies and economies of scale expected from combining the Practice and ICRI and centrally managing the two with TOI Management. The establishment of the allocation to goodwill and identifiable intangible assets requires the extensive use of accounting estimates and management judgement. The fair values assigned to the assets acquired are based on estimates and assumptions from data that is readily available. All of the acquired goodwill is deductible for tax purposes. Unaudited Supplemental Pro Forma Information The pro forma results presented below include the effects of the Acquisition as if it had occurred on January 1, 2018. The pro forma results for the year ended December 31, 2018 include the additional amortization resulting from the adjustments to the value of intangible assets resulting from purchase accounting. The pro forma results do not include any anticipated synergies or other expected benefits of the acquisitions. The pro forma information does not purport to be indicative of what our results of operations would have been if the Acquisition had in fact occurred at the beginning of the period presented and is not intended to be a projection of our future results of operations. Transaction expenses are included within the pro forma results. The unaudited pro forma combined revenue and net income for the twelve months ended December 31, 2018 are $113,160,114 and $2,136,657 respectively.

As described in Note 2—Restatement of Previously Issued Financial Statements, the Company’s financial statements for the period as of December 31, 2020, and the year ended December 31, 2020, as of September 30, 2020 and for the three and nine months ended September 30, 2020, as of June 30, 2020 and for the three and six months ended June 30, 2020, and as of March 31, 2020 and for the three months ended March 31, 2020 (collectively, the “2020 Affected Periods”), are restated in this Annual Report on Form 10-K/A (Amendment No. 2) (this “Annual Report”) to correct the misapplication of accounting guidance related to the redeemable Class A common stock and earnings per share in the Company’s previously issued audited and unaudited condensed financial statements for such periods. The restated financial statements are indicated as “Restated” in the audited and unaudited condensed financial statements and accompanying notes, as applicable. See Note 2—Restatement of Previously Issued Financial Statements for further discussion.
Principles of Consolidation	Basis of Presentation and Principles of Consolidation The accompanying unaudited condensed consolidated financial statements are presented in U.S. dollars in conformity with accounting principles generally accepted in the United States of America (“GAAP”) for financial information and pursuant to the rules and regulations of the SEC. Accordingly, they do not include all of the information and footnotes required by GAAP. In the opinion of management, the unaudited condensed consolidated financial statements reflect all adjustments, which include only normal recurring adjustments necessary for the fair statement of the balances and results for the period presented. Operating results for the period for the three and nine months ended September 30, 2021, are not necessarily indicative of the results that may be expected for the period ending December 31, 2021. The unaudited condensed consolidated financial statements of the Company include its wholly owned subsidiaries in connection with the proposed business combination (as described below). All inter-company accounts and transactions are eliminated in consolidation. The accompanying unaudited condensed consolidated financial statements should be read in conjunction with the audited financial statements and notes thereto included in the Form 10-K/A filed by the Company with the SEC on May 24, 2021.
Use of Estimates	Use of Estimates The preparation of unaudited condensed consolidated financial statements in conformity with GAAP requires the Company’s 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 unaudited condensed consolidated financial statements and the reported amounts of revenue and expenses during the reporting period. Making estimates requires management to exercise significant judgment. It is at least reasonably possible that the estimate of the effect of a condition, situation or set of circumstances that existed at the date of the unaudited condensed consolidated financial statements, which management considered in formulating its estimate, could change in the near term due to one or more future confirming events. One of the more significant accounting estimates included in these unaudited condensed financial statements is the determination of the fair value of the derivative warrant liabilities. Accordingly, the actual results could differ significantly from those estimates.

Net Income (Loss) Per Share	Net Income (Loss) Per Share of Common Stock The Company complies with accounting and disclosure requirements of FASB ASC Topic 260, “Earnings Per Share.” The Company has two classes of shares, which are referred to as Class A common stock and Class B common stock. Income and losses are shared pro rata between the two classes of shares. Net income (loss) per share of common stock is calculated by dividing the net income (loss) by the weighted average shares of common stock outstanding for the respective period. The calculation of diluted net income (loss) per share of common stock does not consider the effect of the warrants issued in connection with the Initial Public Offering and the Private Placement to purchase an aggregate of 9,483,334 shares of common stock in the calculation of diluted income (loss) per share, because their exercise is contingent upon future events and their inclusion would be anti-dilutive under the treasury stock method. As a result, diluted net income (loss) per share is the same as basic net income (loss) per share of common stock for the three and nine months ended September 30, 2021 and 2020. Accretion associated with the redeemable Class A common stock is excluded from earnings per share as the redemption value approximates fair value. The following table presents a reconciliation of the numerator and denominator used to compute basic and diluted net income (loss) per share for each class of common stock: For the Three Months Ended September 30, For the Nine Months Ended September 30 2021 2020 2021 2020 Class A Class B Class A Class B Class A Class B Class A Class B Basic and diluted net income (loss) per share of common stock: Numerator: Allocation of net income - basic $ (345,627) $ (86,407) $ (1,933,328) $ (483,332) $ (693,980) $ (173,495) $ (4,378,377) $ (1,433,857) Allocation of net income - diluted $ (345,627) $ (86,407) $ (1,933,328) $ (483,332) $ (693,980) $ (173,495) $ (4,340,374) $ (1,471,860) Denominator: Basic weighted average common shares outstanding 23,000,000 5,750,000 23,000,000 5,750,000 23,000,000 5,750,000 16,956,204 5,552,920 Diluted weighted average common shares outstanding 23,000,000 5,750,000 23,000,000 5,750,000 23,000,000 5,750,000 16,956,204 5,750,000 Basic net income (loss) per share of common stock $ (0.02) $ (0.02) $ (0.08) $ (0.08) $ (0.03) $ (0.03) $ (0.26) $ (0.26) Diluted net income (loss) per share of common stock $ (0.02) $ (0.02) $ (0.08) $ (0.08) $ (0.03) $ (0.03) $ (0.26) $ (0.26)	Net Income (Loss) Per Share of Common Stock The Company complies with accounting and disclosure requirements of FASB ASC Topic 260, “Earnings Per Share.” The Company has two classes of shares, which are referred to as Class A common stock and Class B common stock.

Emerging Growth Company	Emerging Growth Company The Company is an “emerging growth company,” as defined in Section 2(a) of the Securities Act of 1933, as amended (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 stockholder approval of any golden parachute payments not previously approved. Further, section 102(b)(1) of the JOBS Act exempts emerging growth companies from being required to comply with new or revised financial accounting standards until private companies (that is, those that have not had a Securities Act registration statement declared effective or do not have a class of securities registered under the Securities Exchange Act of 1934, as amended) 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 an election to opt out is irrevocable. We have 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, we, 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 unaudited condensed consolidated financial statements with those of 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 accountant standards used.

Income Taxes	Income Taxes The Company complies with the accounting and reporting requirements of Financial Accounting Standards Board Accounting Standard Codification, or ASC, 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. There were no unrecognized tax benefits as of September 30, 2021, and as of December 31, 2020. ASC 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 as income tax expense. No amounts were accrued for the payment of interest and penalties as of September 30, 2021, and December 31, 2020. The Company is currently not aware of any issues under review that could result in significant payments, accruals or material deviation from its position. The Company is subject to income tax examinations by major taxing authorities since inception.

Fair Value Measurements	Fair Value Measurements Fair value is defined as the price that would be received for sale of an asset or paid for transfer of a liability, in an orderly transaction between market participants at the measurement date. GAAP establishes a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). These tiers consist of: ● Level 1: Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities; ● Level 2: Quoted prices in markets that are not active or financial instruments for which significant inputs to models are observable (including but not limited to quoted prices for similar securities, interest rates, foreign exchange rates, volatility and credit risk), either directly or indirectly; ● Level 3: Prices or valuations that require significant unobservable inputs (including the Management’s assumptions in determining fair value measurement). In some circumstances, the inputs used to measure fair value might be categorized within different levels of the fair value hierarchy. In those instances, the fair value measurement is categorized in its entirety in the fair value hierarchy based on the lowest level input that is significant to the fair value measurement. As of September 30, 2021, the carrying values of cash, accounts payable, accrued expenses, prepaid expenses and franchise tax payable approximate their fair values due to the short-term nature of the instruments. The Company’s investments held in Trust Account are comprised of investments in U.S. Treasury securities with an original maturity of 185 days or less or investments in money market funds that comprise only U.S. Treasury securities and are recognized at fair value. The fair value of investments held in Trust Account is determined using quoted prices in active markets.

Accordingly, they do not include all of the information and note disclosures required by U.S. generally accepted accounting principles (“GAAP”) for complete financial statements. However, the Company believes that the disclosures are adequate to make that information not misleading. In the opinion of management, all adjustments (of normal and recurring nature) considered necessary for fair presentation have been reflected in these interim statements. As such, the information included in the accompanying unaudited interim condensed consolidated financial statements should be read in conjunction with the Company’s audited consolidated financial statements and notes as of, and for the year ended December 31, 2020, issued on June 27, 2021.

Noncontrolling interests in less-than-wholly-owned consolidated subsidiaries of the Company are presented as a component of total equity, to the extent they are material, to distinguish between the interests of the Company and the interests of the noncontrolling owners. Revenues, expenses, and income from these subsidiaries are included in the consolidated amounts as presented on the consolidated statements of operations. The Company holds variable interests in clinical practices, for which it cannot legally own, as a result of entering into master services agreements (“MSAs”) with such practices. TOI Parent holds a variable interest in TOI CA, which is a VIE. The Company is the primary beneficiary of TOI CA and thus, consolidates TOI CA in its financial statements. Further, as a result of the February 2021 acquisition, discussed in Note 16, the Company holds an additional variable interest in TOI FL, which was determined to be a VIE. The Company determined that it is a primary beneficiary of TOI FL and thus, consolidates the entity in its financial statements. As discussed in Note 17, the shareholders of the Company’s consolidating VIEs own a minority of the issued and outstanding common shares of the Company.

Net Income (Loss) Per Share	Net Income (Loss) Per Share The Company has not issued substantive common shares since inception. The Company’s Series A Preferred Shares are considered in-substance common stock since the net income (loss) of the Company is attributable to the Series A Preferred shareholders, and therefore, they are included in the denominator to calculate net income (loss) per share. Basic net income (loss) per share is calculated by dividing net income (loss) attributable to TOI Parent, Inc. by the weighted average Series A Preferred Shares, on an as-converted basis (see Note 19), and common shares issued and outstanding during the period. Diluted net income (loss) per share is calculated by dividing net income (loss) by the weighted average number of Series A Preferred Shares and common shares used in the basic income (loss) per share calculation plus the number of potential common shares that would be issued assuming exercise of all potentially dilutive instruments. Potentially dilutive instruments are excluded from the calculation of diluted income (loss) per share if the effect of including such instruments is anti-dilutive. Given the Company incurred a net loss in each period presented, the stock options outstanding during each period are anti-dilutive. As such, diluted net loss per share is the same as basic net loss per share for each period presented.	Net Loss Per Share The Company has not issued substantive common shares since inception.

Emerging Growth Company	Emerging Growth Company Pursuant to the special purpose acquisition company (“SPAC”) transaction described in Note 22, the Company anticipates qualifying as an “emerging growth company,” as defined in Section 2(a) of the Securities Act of 1933, 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. 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.

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.
Revenue Recognition		Revenue Recognition The Company follows the accounting requirements of Accounting Standard Codification Topic No. 606, Revenue from Contracts with Customers 1. Identification of the contract, or contracts, with a customer. 2. Identification of the performance obligations in the contract. 3. Determination of the transaction price. 4. Allocation of the transaction price to the performance obligations in the contract. 5. Recognition of revenue when, or as, we satisfy a performance obligation. The Company receives payments from the following sources for services rendered: (i) commercial insurers; (ii) the federal government under the Medicare program administered by the Centers for Medicare and Medicaid Services (“CMS”); (iii) state governments under the Medicaid and other programs; (iv) other third-party payors (e.g., hospitals and independent practice associations [“IPAs”]); and (v) individual patients and clients. Revenue primarily consists of capitation revenue, fee-for-service (“FFS”) revenue, dispensary revenue, and clinical trials revenue. Revenue is recognized in the period in which services are rendered or the period in which the Company is obligated to provide services. The form of billing and related risk of collection for such services may vary by type of revenue and the payor. The following paragraphs provide a summary of the principal forms of the Company’s billing arrangements and how revenue is recognized for each. Capitation Capitation revenues of the Company consist primarily of fees for medical services provided to patients by the Company under a capitated arrangement with various managed care organizations. Capitation revenue is paid monthly to the Company based on the number of enrollees assigned to the Company by the contracted managed care organization (per member, per month; or “PMPM”). Capitation contracts generally have a legal term of one year or longer. Capitation contracts have a single performance obligation that is a stand ready obligation to perform healthcare services to the population of enrolled members and constitutes a series for the provision of managed healthcare services for the term of the contract, which is deemed to be one month since the mix of patient-customers can and do change month over month. The transaction price for capitation contracts is variable as it primarily includes PMPM fees associated with unspecified membership that fluctuates throughout the contract. The Company generally estimates the transaction price using the most likely methodology and amounts are only included in the transaction price to the extent that it is probable that a significant reversal of cumulative revenue will not occur once any uncertainty is resolved. Certain contracts include terms for a capitation deduction where the cost of out-of-network referrals of members by the Company are deducted from the future payment. The deductions vary depending on the payor and are often not known until a future period. As such, the Company adjusts the transaction price for capitation deductions based on historic experience such that the amount of capitation revenue is constrained to the extent that it is not probable a significant reversal of revenue will occur in the future. Revenue is recognized in the month services are rendered on the basis of the transaction price established at that time. If subsequent information resolves uncertainties related to the transaction price, adjustments will be recognized in the period they are resolved. When payment has been received but services have not yet been rendered, the payment is recognized as a contract liability. Fee-for-Service Revenue FFS revenue represents revenue earned under contracts in which the Company bills and collects for medical services rendered by the Company’s employed physicians. The terms for FFS contracts are short in duration and only last for the period over which services are rendered (typically, one day). FFS revenue consists of fees for medical services provided to patients. These medical services are distinct since the patient can benefit from the medical services on their own. Each service constitutes a single performance obligation for which the patient accepts and receives the benefit of the medical services as they are performed. Under the FFS arrangements, the Company bills third-party payors and patients for patient care services provided and receives payment. Payments for services provided are generally less than billed charges. The Company records revenue net of an allowance for contractual adjustments, which represents the net revenue expected to collected from third-party payors (including managed care, commercial, and governmental payors such as Medicare and Medicaid), and patients. These expected collections are based on fees and negotiated payment rates in the case of third-party payors, the specific benefits provided for under each patient’s healthcare plans, mandated payment rates in the case of Medicare and Medicaid programs, and historical cash collections (net of recoveries). The transaction price from FFS arrangements is variable in nature because fees are based on patient encounters, credits due to patients, and reimbursement of provider costs, all of which can vary from period to period. The Company estimates the transaction price using the most likely methodology and amounts are only included in the net transaction price to the extent that it is probable that a significant reversal of cumulative revenue will not occur once any uncertainty is resolved. As a practical expedient, the Company adopted a portfolio approach to determine the transaction price for the medical services provided under FFS arrangements. Under this approach, the Company bifurcated the types of services provided and grouped health plans with similar fees and negotiated payment rates. At these levels, portfolios share the characteristics conducive to ensuring that the results do not materially differ from the standard applied to individual patient contracts related to each medical service provided. The recognition of net revenue (gross charges less contractual allowances) from such services is dependent on such factors as proper completion of medical charts following a patient visit, the forwarding of such charts to the Company’s billing center for medical coding and entering into the Company’s billing system, and the verification of each patient’s submission or representation at the time services are rendered as to the payor(s) responsible for payment of such services. Revenue is recorded on the date the services are rendered based on the information known at the time of entering of such information into the Company’s billing systems as well as an estimate of the revenue associated with medical services. When the performance obligation is not satisfied, the billing is recognized as a contract liability. Dispensary The Company sells oral prescription drugs directly through its dispensaries. Each prescription filled and delivered to the customer is a distinct performance obligation. The transaction price for the prescriptions is based on fee schedules set by various pharmacy benefit managers (“PBMs”) and other third party payors. The fee schedule is often subject to direct and indirect remuneration (“DIR”) fees, which are based primarily on pre-established metrics. DIR fees may be assessed in periods after payments are received against future payments. The Company estimates DIR fees to arrive at the transaction price for prescriptions. The Company recognizes revenue based on the transaction at the time the customer takes possession of the oral drug. Clinical Trials Revenue The Company enters into contracts to perform clinical research trials. The terms for clinical trial contracts last many months as the clinical research is performed. Each contract represents a single, integrated set of research activities and thus is a single performance obligation. The performance obligation is satisfied over time as the output is captured in data and documentation that is available for the customer to consume over the course of arrangement and furthers progress of the clinical trial. Under the clinical trial contracts, the Company receives a fixed payment for administrative, set-up, and close-down fees; a fixed amount for each patient site visit; and certain expense reimbursements. Under ASC 606, the Company has elected to recognize revenue for these arrangements using the ‘as-invoiced’ practical expedient. The Company invoices the customer periodically based on the progress of the trial such that each invoice captures the revenue earned to date based on the state of the trial as established between the Company and the customer.
Direct Costs of Sales		Direct Costs of Sales Direct cost of sales primarily consists of wages paid to clinical personnel and other health professionals, oral and IV drug costs, and other medical supplies used to provide patient care. The Company’s costs for clinical personnel wages are expensed as incurred and the Company’s costs for inventory and medical supplies are expensed when used, generally by applying the specific identification method.
Cash		Cash Cash consists of deposits with banking institutions. The carrying value of the Company’s cash approximates fair value due to the short-term maturity of these instruments (less than three months).
Accounts Receivable		Accounts Receivable The Company accounts for accounts receivable under Accounting Standard Codification Topic No. 310, Receivables For third-party payors including Medicare, Medicaid, managed care providers, and commercial payors, the collectable amount is based on the estimated contractual reimbursement percentage, which is based on current contract prices or historical paid claims data by payor. For self-pay accounts receivable, which includes patients who are uninsured and the patient responsibility portion for patients with insurance, the collectable amount is determined using estimates of historical collection experience without regard to aging category.These estimates are adjusted for estimated conversions of patient responsibility portions, expected recoveries, and any anticipated changes in trends. Accounts receivable can be impacted by the effectiveness of the Company’s collection efforts.Additionally, significant changes in payor mix, business office operations, economic conditions, or trends in federal and state governmental healthcare coverage could affect the collectable amount of accounts receivable. The Company maintains reserves for potential credit losses on accounts receivable. Management reviews the composition of accounts receivable and analyzes historical bad debts, customer concentrations,customer credit worthiness, current economic trends, and changes in customer payment patterns to evaluate the adequacy of these reserves. The Company also regularly analyzes the ultimate collectability of accounts receivable after certain stages of the collection cycle using a look-back analysis to determine the amount of receivables subsequently collected, and adjustments are recorded when necessary. The Company continuously monitors its collections of receivables and its policy is to write off receivables when they are determined to be uncollectible. As of December 31, 2020 and 2019, the Company does not have an allowance for doubtful accounts.
Inventories		Inventories The Company accounts for inventory under Accounting Standard Codification Topic No. 330, Inventory The Company receives purchase discounts on products purchased. Contractual arrangements with vendors, including manufacturers and wholesalers, normally provide for the Company to receive purchase discounts from established list prices in one, or a combination, of the following forms: (i) a direct discount at the time of purchase or (ii) a discount for the prompt payment of invoices. Additionally, in other circumstances, the Company may receive rebates when products are purchased indirectly from a manufacturer (e.g., through a wholesaler). These rebates are recognized when intravenous chemotherapy drugs and oral prescription drugs are dispensed and are generally calculated by manufacturers within 30 days after the end of each completed quarter. The Company also receives additional rebate under its wholesaler contracts if it exceeds contractually defined annual purchase volumes. Purchase rebates are recorded as reductions to cost of services.
Property and Equipment, net		Property and Equipment, net The Company accounts for property and equipment under Accounting Standard Codification Topic No. 360, Property, Plant, and Equipment When events or changes in circumstances indicate that the carrying amount of long-lived assets, including property and equipment, or other long-lived assets, may not be recoverable, an evaluation of the recoverability of currently recorded costs is performed. When an evaluation is performed, the estimated value of undiscounted future net cash flows associated with the asset groups is compared to the asset groups’ carrying value to determine if a write-down to fair value is required. If such assets are considered to be impaired, the impairment to be recognized is measured as the amount by which the carrying amount of the asset group exceeds the fair value of the assets. There were no impairment adjustments recorded for long- lived assets during the years ended December 31, 2020, 2019, the Successor Predecessor
Accounts payable, Accrued Expenses, and Other Current Liabilities		Accounts Payable, Accrued Expenses, and Other Current Liabilities Accounts payable primarily consists of unpaid invoices related to routine operating expenses. Accrued expenses and other current liabilities primarily consist of accruals made for payroll expenses, deferred capitation, and FFS revenue.
Leases		Leases Lease agreements are evaluated to determine whether they are capital or operating leases in accordance with Accounting Standards Codification, Topic No. 840, Leases
Goodwill and Intangible Assets		Goodwill and Intangible Assets The Company accounts for goodwill and intangible assets under Accounting Standards Codification Topic No. 350, Goodwill and Other Goodwill is not amortized but is required to be evaluated for impairment at the same time every year. The Company performs its annual testing of impairment for goodwill in the fourth quarter of each year. When impairment indicators are identified, the Company compares the reporting unit’s fair value to its carrying amount, including goodwill. An impairment loss is recognized as the difference, if any, between the reporting unit’s carrying amount and its fair value to the extent the difference does not exceed the total amount of goodwill allocated to the reporting unit. The Company performed a qualitative analysis and determined that no indicators of impairment existed at December 31, 2020 and 2019 and therefore, there was no goodwill impairment charge during the years ended December 31, 2020, 2019, and the Successor Period, as a result of the Company’s annual impairment evaluation. Under ASC 350, finite-lived intangible assets are stated at acquisition-date fair value. Intangible assets are amortized using the straight-line method. Finite-lived intangible assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. When circumstances indicate that recoverability may be impaired, the Company assesses its ability to recover the carrying value of the asset group from the expected future pre-tax cash flows (undiscounted and without interest charges) of the related operations. If these cash flows are less than the carrying value of such asset, an impairment loss is recognized for the difference between estimated fair value and carrying value. Fair value is determined based on appropriate valuation techniques. The Company performed a qualitative analysis and determined that there were no indicators of impairment of its finite-lived intangible assets during the years ended December 31, 2020, 2019, and the Successor Period.
Debt		Debt The Company accounts for debt net of debt issuance costs. Debt issuance costs are capitalized, netted against the related debt for presentation purposes, and amortized to interest expense over the terms of the related debt using the effective interest method.
Income Taxes		Income Taxes The Company accounts for income taxes under the asset and liability method under Accounting Standards Codification Topic No. 740, Income Taxes
Share-Based Compensation Plan		Share-Based Compensation Plan The Company accounts for share-based compensation under Accounting Standards Codification Topic No. 718, Stock Based Compensation Excess tax benefits of awards related to stock option exercises are recognized as an income tax benefit in the statement of operations and reflected in operating activities in the statement of cash flows.
Commitments and Contingencies		Commitments and Contingencies The Company accounts for contingent liabilities under Accounting Standards Codification Subtopic No. 450-20, Contingencies
Fair Value Measurements		Fair Value Measurements The Company accounts for fair value measurements under Accounting Standards Codification Topic No. 820, Fair Value Measurements ● Level 1 inputs: Unadjusted quoted prices in active markets for identical assets or liabilities accessible to the reporting entity at the measurement date. ● Level 2 inputs: Other than quoted prices included in Level 1 inputs that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the asset or liability. ● Level 3 inputs: Unobservable inputs for the asset or liability used to measure fair value to the extent that observable inputs are not available, thereby allowing for situations in which there is little, if any, market activity for the asset or liability at measurement date.

The new standard requires lessees to record a right-of-use (“ROU”) asset and a corresponding lease liability on the balance sheet (with the exception of short-term leases), whereas under current accounting standards the Company’s lease portfolio consists primarily of operating leases and is not recognized on its consolidated balance sheets. The Company will adopt ASC 842 effective January 1, 2022, using the alternative modified transition method and will record a cumulative-effect adjustment to the opening balance of retained earnings as of that date. Prior periods will not be restated. The Company believes the largest impact will be on the consolidated balance sheets for the accounting of facilities-related leases, which represents a majority of its operating leases it has entered into as a lessee. These leases will be recognized under the new standard as ROU assets and operating lease liabilities. The Company will also provide expanded disclosures for its leasing arrangements. The results of operations are not expected to significantly change after adoption of the new standard.

Summary of Significant Accounting Policies	Sep. 30, 2021	Dec. 31, 2020
Summary of Significant Accounting Policies	2. Basis of Presentation and Significant Accounting Policies. Basis of Presentation and Principles of Consolidation The accompanying unaudited condensed consolidated financial statements are presented in U.S. dollars in conformity with accounting principles generally accepted in the United States of America (“GAAP”) for financial information and pursuant to the rules and regulations of the SEC. Accordingly, they do not include all of the information and footnotes required by GAAP. In the opinion of management, the unaudited condensed consolidated financial statements reflect all adjustments, which include only normal recurring adjustments necessary for the fair statement of the balances and results for the period presented. Operating results for the period for the three and nine months ended September 30, 2021, are not necessarily indicative of the results that may be expected for the period ending December 31, 2021. The unaudited condensed consolidated financial statements of the Company include its wholly owned subsidiaries in connection with the proposed business combination (as described below). All inter-company accounts and transactions are eliminated in consolidation. The accompanying unaudited condensed consolidated financial statements should be read in conjunction with the audited financial statements and notes thereto included in the Form 10-K/A filed by the Company with the SEC on May 24, 2021. Restatement of Previously Reported Financial Statements In preparation of the Company’s unaudited condensed financial statements for the quarterly period ended September 30, 2021, the Company concluded it should restate its previously issued financial statements to classify all Class A common stock subject to possible redemption in temporary equity. In accordance with technical accounting guidance on redeemable equity instruments in ASC 480-10-S99, redemption provisions not solely within the control of the Company, require Class A common stock subject to redemption to be classified outside of permanent equity. The Company had previously classified a portion of its Class A common stock in permanent equity. Although the Company did not specify a maximum redemption threshold, its charter currently provides that the Company will not redeem its Public Shares in an amount that would cause its net tangible assets to be less than $5,000,001. Previously, the Company did not consider redeemable shares classified as temporary equity as part of net tangible assets. Effective with these condensed financial statements, the Company revised this interpretation to include temporary equity in net tangible assets. In connection with the change in presentation for the Class A common stock subject to possible redemption, the Company restated its earnings per share calculation to allocate income and losses shared pro rata between the two classes of shares. This presentation contemplates a Business Combination as the most likely outcome, in which case, both classes of shares participate pro rata in the income and losses of the Company. In accordance with SEC Staff Accounting Bulletin No. 99, “Materiality,” and SEC Staff Accounting Bulletin No. 108, “Considering the Effects of Prior Year Misstatements when Quantifying Misstatements in Current Year Financial Statements,” the Company evaluated the corrections and has determined that the related impact was material to the previously filed financial statements that contained the error, reported in the Company’s Quarterly Reports on Form 10-Q for the quarterly periods ended March 31, 2021 and June 30, 2021 (the “Affected Quarterly Periods”). Therefore, the Company, in consultation with its Audit Committee, concluded that the Affected Quarterly Periods should be restated to present all Class A common stock subject to possible redemption as temporary equity and to recognize accretion from the initial book value to redemption value at the time of its Initial Public Offering. As such, the Company is reporting these restatements to those periods in this quarterly report. The impact of the restatement on the financial statements for the Affected Quarterly Periods is presented below. The table below presents the effect of the financial statement adjustments related to the restatement discussed above of the Company’s previously reported unaudited condensed balance sheet as of March 31, 2021: As of March 31, 2021 (unaudited) As Reported Adjustment As Restated Total assets $ 231,036,262 $ — $ 231,036,262 Total liabilities $ 19,386,072 $ — $ 19,386,072 Class A common stock subject to possible redemption 206,650,180 23,349,820 230,000,000 Preferred stock — — — Class A common stock 233 (233) — Class B common stock 575 — 575 Additional paid-in capital 7,656,106 (7,656,106) — Accumulated deficit (2,656,904) (15,693,481) (18,350,385) Total stockholders’ equity (deficit) $ 5,000,010 $ (23,349,820) $ (18,349,810) Total Liabilities, Class A Common Stock Subject to Possible Redemption and Stockholders’ Equity (Deficit) $ 231,036,262 $ — $ 231,036,262 Shares of Class A common stock subject to possible redemption 20,665,018 2,334,982 23,000,000 Shares of Class A common stock 2,334,982 (2,334,982) — The impact on the unaudited condensed statement of stockholders’ equity is consistent with the changes to the impacted stockholders’ equity accounts described above.

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 Securities Exchange Act of 1934, as amended) 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 an election to opt out is irrevocable. We have 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, we, 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 unaudited condensed consolidated financial statements with those of 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 accountant standards used. Proposed Business Combination On June 28, 2021, the Company entered into an Agreement and Plan of Merger (as it may be amended, supplemented or otherwise modified from time to time, the “Merger Agreement”) by and among DFP, Orion Merger Sub I, Inc., a Delaware corporation and a direct, wholly-owned subsidiary of DFP (“First Merger Sub”), Orion Merger Sub II, LLC, a Delaware limited liability company and a direct, wholly-owned subsidiary of DFP (“Second Merger Sub”) and TOI Parent, Inc., a Delaware corporation (“TOI”). Refer to the Company’s Current Report on Form 8-K, and Proxy Statement/Prospectus filed with the SEC on June 29, 2021 and October 22, 2021, respectively. Use of Estimates The preparation of unaudited condensed consolidated financial statements in conformity with GAAP requires the Company’s 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 unaudited condensed consolidated financial statements and the reported amounts of revenue and expenses during the reporting period. Making estimates requires management to exercise significant judgment. It is at least reasonably possible that the estimate of the effect of a condition, situation or set of circumstances that existed at the date of the unaudited condensed consolidated financial statements, which management considered in formulating its estimate, could change in the near term due to one or more future confirming events. One of the more significant accounting estimates included in these unaudited condensed financial statements is the determination of the fair value of the derivative warrant liabilities. Accordingly, the actual results could differ significantly from those estimates. Concentration of Credit Risk Financial instruments that potentially subject the Company to concentrations of credit risk consist of cash accounts in a financial institution, which, at times, may exceed the Federal Deposit Insurance Corporation limit of $250,000, and investments held in Trust Account. The Company has not experienced losses on these accounts and management believes the Company is not exposed to significant risks on such accounts. Investments Held in Trust Account The Company’s portfolio of investments is comprised of 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 investments in money market funds that invest in U.S. government securities and generally have a readily determinable fair value, or a combination thereof. When the Company’s investments held in the Trust Account are comprised of U.S. government securities, the investments are classified as trading securities. When the Company’s investments held in the Trust Account are comprised of money market funds, the investments are recognized at fair value. Trading securities and investments in money market funds are presented on the balance sheets at fair value at the end of each reporting period. Gains and losses resulting from the change in fair value of these securities is included in interest income on investments held in the Trust Account in the accompanying unaudited condensed consolidated statements of operations. The estimated fair values of investments held in the Trust Account are determined using available market information. Cash and Cash Equivalents The Company considers all short-term investments with an original maturity of three months or less when purchased to be cash equivalents. The Company had no cash equivalents as of September 30, 2021 and December 31, 2020. Fair Value of Financial Instruments The fair value of the Company’s assets and liabilities which qualify as financial instruments under the FASB ASC Topic 820, “Fair Value Measurements,” equal or approximate the carrying amounts represented in the condensed consolidated balance sheets. Fair Value Measurements Fair value is defined as the price that would be received for sale of an asset or paid for transfer of a liability, in an orderly transaction between market participants at the measurement date. GAAP establishes a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). These tiers consist of: ● Level 1: Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities; ● Level 2: Quoted prices in markets that are not active or financial instruments for which significant inputs to models are observable (including but not limited to quoted prices for similar securities, interest rates, foreign exchange rates, volatility and credit risk), either directly or indirectly; ● Level 3: Prices or valuations that require significant unobservable inputs (including the Management’s assumptions in determining fair value measurement). In some circumstances, the inputs used to measure fair value might be categorized within different levels of the fair value hierarchy. In those instances, the fair value measurement is categorized in its entirety in the fair value hierarchy based on the lowest level input that is significant to the fair value measurement. As of September 30, 2021, the carrying values of cash, accounts payable, accrued expenses, prepaid expenses and franchise tax payable approximate their fair values due to the short-term nature of the instruments. The Company’s investments held in Trust Account are comprised of investments in U.S. Treasury securities with an original maturity of 185 days or less or investments in money market funds that comprise only U.S. Treasury securities and are recognized at fair value. The fair value of investments held in Trust Account is determined using quoted prices in active markets. Derivative Warrant Liabilities The Company does not use derivative instruments to hedge exposures to cash flow, market, or foreign currency risks. The Company evaluates all of its financial instruments, including issued stock purchase warrants, to determine if such instruments are derivatives or contain features that qualify as embedded derivatives, pursuant to ASC 480 and FASB ASC Topic 815, “Derivatives and Hedging” (“ASC 815”). The classification of derivative instruments, including whether such instruments should be recorded as liabilities or as equity, is re-assessed at the end of each reporting period. The 5,750,000 Public Warrants and the 3,733,334 Private Placement Warrants are recognized as derivative liabilities in accordance with ASC 815. Accordingly, the Company recognizes the warrant instruments as liabilities at fair value and adjusts the instruments to fair value at each reporting period. The liabilities are subject to re-measurement at each balance sheet date until exercised, and any change in fair value is recognized in the Company’s unaudited condensed consolidated statements of operations. The fair value of the Public Warrants issued in connection with the Public Offering and Private Placement Warrants were initially measured at fair value using a Monte Carlo simulation model and subsequently, the fair value of the Private Placement Warrants have been estimated using a Monte Carlo simulation model each measurement date. The fair value of Public Warrants issued in connection with the Initial Public Offering have subsequently been measured based on the listed market price of such warrants. Offering Costs Associated with the Initial Public Offering Offering costs consisted of legal, accounting, underwriting fees and other costs incurred through the Initial Public Offering that were directly related to the Initial Public Offering. Offering costs were allocated to the separable financial instruments issued in the Initial Public Offering based on a relative fair value basis, compared to total proceeds received. Offering costs associated with derivative warrant liabilities were expensed as incurred and presented as non-operating expenses in the condensed statements of operations. Offering costs associated with the Class A common stock issued were charged against the carrying value of the shares of Class A common stock upon the completion of the Initial Public Offering. The Company classifies deferred underwriting commissions as non-current liabilities as their liquidation is not reasonably expected to require the use of current assets or require the creation of current liabilities. Class A Common Stock Subject to Possible Redemption The Company accounts for its Class A common stock subject to possible redemption in accordance with the guidance in ASC Topic 480 “Distinguishing Liabilities from Equity.” Shares of Class A common stock subject to mandatory redemption (if any) are classified as liability instruments and are measured at fair value. Shares of conditionally redeemable Class A common stock (including Class A common stock that feature redemption rights that are either within the control of the holder or subject to redemption upon the occurrence of uncertain events not solely within the Company’s control) are classified as temporary equity. At all other times, shares of Class A common stock are classified as stockholders’ equity. The Company’s Class A common stock feature certain redemption rights that are considered to be outside of the Company’s control and subject to the occurrence of uncertain future events. Accordingly, as of September 30, 2021, and December 31, 2020, 23,000,000 shares of Class A common stock subject to possible redemption are presented as temporary equity, outside of the stockholders’ equity section of the Company’s condensed consolidated balance sheets. Under ASC 480-10-S99, the Company has elected to recognize changes in the redemption value immediately as they occur and adjust the carrying value of the security to equal the redemption value at the end of each reporting period. This method would view the end of the reporting period as if it were also the redemption date for the security. Effective with the closing of the Initial Public Offering, the Company recognized the accretion from initial book value to redemption amount, which resulted in charges against additional paid-in capital (to the extent available) and accumulated deficit. Net Income (Loss) Per Share of Common Stock The Company complies with accounting and disclosure requirements of FASB ASC Topic 260, “Earnings Per Share.” The Company has two classes of shares, which are referred to as Class A common stock and Class B common stock. Income and losses are shared pro rata between the two classes of shares. Net income (loss) per share of common stock is calculated by dividing the net income (loss) by the weighted average shares of common stock outstanding for the respective period. The calculation of diluted net income (loss) per share of common stock does not consider the effect of the warrants issued in connection with the Initial Public Offering and the Private Placement to purchase an aggregate of 9,483,334 shares of common stock in the calculation of diluted income (loss) per share, because their exercise is contingent upon future events and their inclusion would be anti-dilutive under the treasury stock method. As a result, diluted net income (loss) per share is the same as basic net income (loss) per share of common stock for the three and nine months ended September 30, 2021 and 2020. Accretion associated with the redeemable Class A common stock is excluded from earnings per share as the redemption value approximates fair value. The following table presents a reconciliation of the numerator and denominator used to compute basic and diluted net income (loss) per share for each class of common stock: For the Three Months Ended September 30, For the Nine Months Ended September 30 2021 2020 2021 2020 Class A Class B Class A Class B Class A Class B Class A Class B Basic and diluted net income (loss) per share of common stock: Numerator: Allocation of net income - basic $ (345,627) $ (86,407) $ (1,933,328) $ (483,332) $ (693,980) $ (173,495) $ (4,378,377) $ (1,433,857) Allocation of net income - diluted $ (345,627) $ (86,407) $ (1,933,328) $ (483,332) $ (693,980) $ (173,495) $ (4,340,374) $ (1,471,860) Denominator: Basic weighted average common shares outstanding 23,000,000 5,750,000 23,000,000 5,750,000 23,000,000 5,750,000 16,956,204 5,552,920 Diluted weighted average common shares outstanding 23,000,000 5,750,000 23,000,000 5,750,000 23,000,000 5,750,000 16,956,204 5,750,000 Basic net income (loss) per share of common stock $ (0.02) $ (0.02) $ (0.08) $ (0.08) $ (0.03) $ (0.03) $ (0.26) $ (0.26) Diluted net income (loss) per share of common stock $ (0.02) $ (0.02) $ (0.08) $ (0.08) $ (0.03) $ (0.03) $ (0.26) $ (0.26) Income Taxes The Company complies with the accounting and reporting requirements of Financial Accounting Standards Board Accounting Standard Codification, or ASC, 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. There were no unrecognized tax benefits as of September 30, 2021, and as of December 31, 2020. ASC 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 as income tax expense. No amounts were accrued for the payment of interest and penalties as of September 30, 2021, and December 31, 2020. The Company is currently not aware of any issues under review that could result in significant payments, accruals or material deviation from its position. The Company is subject to income tax examinations by major taxing authorities since inception. Recent Accounting Pronouncements In August 2020, the Financial Accounting Standards Board issued Accounting Standard Update (“ASU”) No. 2020-06, Debt—Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging—Contracts in Entity’s Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity The Company’s management does not believe that any other recently issued, but not yet effective, accounting standards updates, if currently adopted, would have a material effect on the accompanying unaudited condensed consolidated financial statements.	Note 3 — Summary of Significant Accounting Policies Basis of presentation The Company’s financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”) for financial information and pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). The Company has no subsidiaries. As described in Note 2—Restatement of Previously Issued Financial Statements, the Company’s financial statements for the period as of December 31, 2020, and the year ended December 31, 2020, as of September 30, 2020 and for the three and nine months ended September 30, 2020, as of June 30, 2020 and for the three and six months ended June 30, 2020, and as of March 31, 2020 and for the three months ended March 31, 2020 (collectively, the “2020 Affected Periods”), are restated in this Annual Report on Form 10-K/A (Amendment No. 2) (this “Annual Report”) to correct the misapplication of accounting guidance related to the redeemable Class A common stock and earnings per share in the Company’s previously issued audited and unaudited condensed financial statements for such periods. The restated financial statements are indicated as “Restated” in the audited and unaudited condensed financial statements and accompanying notes, as applicable. See Note 2—Restatement of Previously Issued Financial Statements for further discussion. Use of Estimates The preparation of the financial statements in conformity with GAAP requires the Company’s management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Making estimates requires management to exercise significant judgment. It is at least reasonably possible that the estimate of the effect of a condition, situation or set of circumstances that existed at the date of the financial statements, which management considered in formulating its estimate, could change in the near term due to one or more future conforming events. Accordingly, the actual results could differ from those estimates. Cash and Cash Equivalents The Company considers all short-term investments with an original maturity of three months or less when purchased to be cash equivalents. The Company had no cash equivalents as of December 31, 2020, and 2019. Investments Held in the Trust Account The Company’s portfolio of investments held in the Trust Account is comprised of 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 investments in money market funds that invest in U.S. government securities, or a combination thereof. The Company’s investments held in the Trust Account are classified as trading securities. Trading securities are presented on the balance sheet at fair value at the end of each reporting period. Gains and losses resulting from the change in fair value of these securities is included in net gain on investments, dividends and interest held in Trust Account in the accompanying statement of operations. The estimated fair values of investments held in the Trust Account were determined using available market information. Concentration of Credit Risk Financial instruments that potentially subject the Company to concentrations of credit risk consist of cash accounts in a financial institution, which, at times, may exceed the Federal Deposit Insurance Corporation limit of $250,000, and investments held in Trust Account. The Company has not experienced losses on these accounts and management believes the Company is not exposed to significant risks on such accounts. Fair Value of Financial Instruments Fair value is defined as the price that would be received for sale of an asset, or paid for transfer of a liability, in an orderly transaction between market participants at the measurement date. U.S. GAAP establishes a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). These tiers include: ● Level 1, defined as observable inputs such as quoted prices (unadjusted) for identical instruments in active markets; ● Level 2, defined as inputs other than quoted prices in active markets that are either directly or indirectly observable such as quoted prices for similar instruments in active markets or quoted prices for identical or similar instruments in markets that are not active; and ● Level 3, defined as unobservable inputs in which little or no market data exists, therefore requiring an entity to develop its own assumptions, such as valuations derived from valuation techniques in which one or more significant inputs or significant value drivers are unobservable. In some circumstances, the inputs used to measure fair value might be categorized within different levels of the fair value hierarchy. In those instances, the fair value measurement is categorized in its entirety in the fair value hierarchy based on the lowest level input that is significant to the fair value measurement. As of December 31, 2020, and 2019, the carrying values of cash, prepaid expenses, accounts payable, accrued expenses, accrued expenses - related party, and tax obligations approximate their fair values due to the short-term nature of the instruments. The Company’s portfolio of marketable securities held in the Trust Account is comprised mainly of investments in U.S. Treasury securities with an original maturity of 185 days or less. The fair value for trading securities is determined using quoted market prices in active markets. Offering Costs The Company complied with the requirements of the ASC 340-10-S99-1. Offering costs consist of legal, accounting, underwriting fees and other costs incurred that were directly attributable to the Initial Public Offering.. Offering costs are allocated to the separable financial instruments issued in the Initial Public Offering based on a relative fair value basis, compared to total proceeds received. Offering costs associated with warrant liabilities are expensed as incurred, presented as non-operating expenses in the statement of operations. Offering costs associated with the Public Shares were charged to the carrying value of the Class A common stock subject to possible redemption upon the completion of the Initial Public Offering. The Company classifies deferred underwriting commissions as their liquidation is not reasonably expected to require the use of current assets or require the creation of current liabilities. Derivative Warrant Liabilities The Company does not use derivative instruments to hedge its exposures to cash flow, market or foreign currency risks. Management evaluates all of the Company’s financial instruments, including issued warrants to purchase its Class A common stock, to determine if such instruments are derivatives or contain features that qualify as embedded derivatives, pursuant to ASC 480 and ASC 815-15. The classification of derivative instruments, including whether such instruments should be recorded as liabilities or as equity, is re-assessed at the end of each reporting period. The Company issued 5,750,000 warrants to purchase Class A common stock to investors in the Company’s Initial Public Offering, including the over-allotment, and simultaneously issued 3,733,334 Private Placement Warrants. All of the Company’s outstanding warrants are recognized as derivative liabilities in accordance with ASC 815-40. Accordingly, we recognize the warrant instruments as liabilities at fair value and adjust the instruments to fair value at each reporting period. The liabilities are subject to re-measurement at each balance sheet date until exercised, and any change in fair value is recognized in our statement of operations. The fair value of the Public Warrants issued in connection with the Public Offering and Private Placement Warrants were initially measured at fair value using a Monte Carlo simulation model and subsequently, the fair value of the Private Placement Warrants have been estimated using a Monte Carlo simulation model each measurement date. The fair value of Public Warrants issued in connection with the Initial Public Offering have subsequently been measured based on the listed market price of such warrants. Class A Common Stock Subject to Possible Redemption (Restated - See Note 2) The Company accounts for its Class A common stock subject to possible redemption in accordance with the guidance in ASC Topic 480 “Distinguishing Liabilities from Equity.” Class A common stock subject to mandatory redemption (if any) is classified as liability instruments and are measured at fair value. Conditionally redeemable Class A common stock (including Class A common stock that features redemption rights that are either within the control of the holder or subject to redemption upon the occurrence of uncertain events not solely within the Company’s control) are classified as temporary equity. At all other times, Class A common stock is classified as stockholders’ equity. The Company’s Class A common stock feature certain redemption rights that are considered to be outside of the Company’s control and subject to the occurrence of uncertain future events. Accordingly, as of December 31, 2020, 23,000,000 shares of Class A common stock subject to possible redemption are presented as temporary equity, outside of the stockholders’ equity section of the Company’s balance sheets. Under ASC 480-10-S99, the Company has elected to recognize changes in the redemption value immediately as they occur and adjust the carrying value of the security to equal the redemption value at the end of each reporting period. This method would view the end of the reporting period as if it were also the redemption date for the security. Accordingly, effective with the closing of the Initial Public Offering, the Company recognized the accretion from the initial book value to redemption amount, which resulted in charges against paid-in -capital (to the extent available) and accumulated deficit The Class A common stock subject to possible redemption reflected on the balance sheet is reconciled on the following table: Gross proceeds $ 230,000,000 Less: Amount allocated to Public Warrants (6,727,500) Class A common stock issuance costs (10,110,406) Plus: Accretion of carrying value to redemption value 16,837,906 Class A common stock subject to possible redemption $ 230,000,000 Net Income (Loss) Per Share of Common Stock The Company complies with accounting and disclosure requirements of FASB ASC Topic 260, “Earnings Per Share.” The Company has two classes of shares, which are referred to as Class A common stock and Class B common stock. Income and losses are shared pro rata between the two classes of shares. Net income (loss) per share of common stock is calculated by dividing the net income (loss) by the weighted average number of common stock outstanding for the respective period. The calculation of diluted net income (loss) per share of common stock does not consider the effect of the warrants underlying the Units sold in the Initial Public Offering and the Private Placement to purchase an aggregate of 9,483,334 of the Company’s Class A common stock in the calculation of diluted income per share, since their exercise is contingent upon future events and their inclusion would be anti-dilutive under the treasury stock method. Accretion associated with the redeemable Class A common stock is excluded from earnings per share as the redemption value approximates fair value. The table below presents a reconciliation of the numerator and denominator used to compute basic and diluted net loss per share of common stock for each class of common stock: For the Year Ended December 31, 2020 2019 Class A Class B Class A Class B Basic and diluted net income (loss) per share of common stock: Numerator: Allocation of net income $ (6,399,368) $ (1,940,536) $ — $ (2,300) Denominator: Basic and diluted weighted average common shares outstanding 18,475,410 5,602,459 — 5,000,000 Basic and diluted net income (loss) per share of common stock $ (0.35) $ (0.35) $ — $ — Income Taxes The Company complies with the accounting and reporting requirements of Financial Accounting Standards Board Accounting Standard Codification, or FASB ASC, 740, “Income Taxes,” which requires an asset and liability approach to financial accounting and reporting for income taxes.

No amounts were accrued for the payment of interest and penalties as of December 31, 2020 or 2019. The Company is currently not aware of any issues under review that could result in significant payments, accruals or material deviation from its position. The Company is subject to income tax examinations by major taxing authorities since inception. Recent Accounting Pronouncements 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.

Summary of Significant Accounting Policies	Note 2. Summary of Significant Accounting Policies Unaudited Interim Financial Information The accompanying interim condensed consolidated financial statements are unaudited and have been prepared in accordance with Article 10 of Regulation S-X issued by the Securities and Exchange Commission (“SEC”). Accordingly, they do not include all of the information and note disclosures required by U.S. generally accepted accounting principles (“GAAP”) for complete financial statements. However, the Company believes that the disclosures are adequate to make that information not misleading. In the opinion of management, all adjustments (of normal and recurring nature) considered necessary for fair presentation have been reflected in these interim statements. As such, the information included in the accompanying unaudited interim condensed consolidated financial statements should be read in conjunction with the Company’s audited consolidated financial statements and notes as of, and for the year ended December 31, 2020, issued on June 27, 2021. Principles of Consolidation The accompanying unaudited condensed consolidated financial statements include the accounts of TOI Parent, its subsidiaries, all of which are controlled by the Parent through majority voting control or are variable interest entities (“VIEs”) for which TOI Parent (through TOI Management) is the primary beneficiary. The Company consolidates entities in which it has a controlling financial interest based on either the variable interest entity or voting interest model. All significant intercompany balances and transactions have been eliminated in consolidation. Variable Interest Entities The Company consolidates entities for which it has a variable interest and is determined to be the primary beneficiary. Noncontrolling interests in less-than-wholly-owned consolidated subsidiaries of the Company are presented as a component of total equity, to the extent they are material, to distinguish between the interests of the Company and the interests of the noncontrolling owners. Revenues, expenses, and income from these subsidiaries are included in the consolidated amounts as presented on the consolidated statements of operations. The Company holds variable interests in clinical practices, for which it cannot legally own, as a result of entering into master services agreements (“MSAs”) with such practices. TOI Parent holds a variable interest in TOI CA, which is a VIE. The Company is the primary beneficiary of TOI CA and thus, consolidates TOI CA in its financial statements. Further, as a result of the February 2021 acquisition, discussed in Note 16, the Company holds an additional variable interest in TOI FL, which was determined to be a VIE. The Company determined that it is a primary beneficiary of TOI FL and thus, consolidates the entity in its financial statements. As discussed in Note 17, the shareholders of the Company’s consolidating VIEs own a minority of the issued and outstanding common shares of the Company. Business Combinations The Company accounts for all transactions that represent business combinations using the acquisition method of accounting under Accounting Standards Codification Topic No. 805, Business Combinations Segment Reporting The Company presents the financial statements by segment in accordance with Accounting Standard Codification Topic No. 280, Segment Reporting reporting Use of Estimates The preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates under different assumptions or conditions. Significant items subject to such estimates and assumptions include estimated accounts receivable, useful lives and recoverability of long-lived and intangible assets, recoverability of goodwill, fair values of acquired assets and assumed liabilities in business combinations, fair value of goodwill, judgements related to revenue recognition, and deferred income taxes. Net Income (Loss) Per Share The Company has not issued substantive common shares since inception. The Company’s Series A Preferred Shares are considered in-substance common stock since the net income (loss) of the Company is attributable to the Series A Preferred shareholders, and therefore, they are included in the denominator to calculate net income (loss) per share. Basic net income (loss) per share is calculated by dividing net income (loss) attributable to TOI Parent, Inc. by the weighted average Series A Preferred Shares, on an as-converted basis (see Note 19), and common shares issued and outstanding during the period. Diluted net income (loss) per share is calculated by dividing net income (loss) by the weighted average number of Series A Preferred Shares and common shares used in the basic income (loss) per share calculation plus the number of potential common shares that would be issued assuming exercise of all potentially dilutive instruments. Potentially dilutive instruments are excluded from the calculation of diluted income (loss) per share if the effect of including such instruments is anti-dilutive. Given the Company incurred a net loss in each period presented, the stock options outstanding during each period are anti-dilutive. As such, diluted net loss per share is the same as basic net loss per share for each period presented. Emerging Growth Company Pursuant to the special purpose acquisition company (“SPAC”) transaction described in Note 22, the Company anticipates qualifying as an “emerging growth company,” as defined in Section 2(a) of the Securities Act of 1933, 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. 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. Recently Issued Accounting Standards In June 2020, the FASB issued Accounting Standards Update 2020-05, Leases (Topic 842), Effective Dates for Certain Entities Leases (Topic 842) Financial Instruments — Credit Losses (Topic 326), Derivatives and Hedging (Topic 815), and Leases (Topic 842): Effective Dates In February 2016, the FASB issued ASU 2016-02, which amends the existing accounting standards for leases. The new standard requires lessees to record a right-of-use (“ROU”) asset and a corresponding lease liability on the balance sheet (with the exception of short-term leases), whereas under current accounting standards the Company’s lease portfolio consists primarily of operating leases and is not recognized on its consolidated balance sheets. The Company will adopt ASC 842 effective January 1, 2022, using the alternative modified transition method and will record a cumulative-effect adjustment to the opening balance of retained earnings as of that date. Prior periods will not be restated. The Company believes the largest impact will be on the consolidated balance sheets for the accounting of facilities-related leases, which represents a majority of its operating leases it has entered into as a lessee. These leases will be recognized under the new standard as ROU assets and operating lease liabilities. The Company will also provide expanded disclosures for its leasing arrangements. The results of operations are not expected to significantly change after adoption of the new standard. In June 2016, the FASB issued Accounting Standards Update 2016-13, Measurement of Credit Losses on Financial Instruments Codification Improvements to Topic 326, Financial Instruments — Credit Losses Codification Improvements to Topic 326, Financial Instruments — Credit Losses, Topic 815, Derivatives and Hedging, and Topic 825, Financial Instruments Financial Instruments — Credit Losses (Topic 326): Targeted Transition Relief Financial Instruments — Credit Losses (Topic 326), Derivatives and Hedging (Topic 815), and Leases (Topic 842): Effective Dates, and ASU 2019-11, Codification Improvements to Topic 326, Financial Instruments — Credit Losses In January 2017, the FASB issued Accounting Standards Update 2017-04, Intangibles — Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment In December 2019, the FASB issued Accounting Standards Update 2019-12, Simplifying the Accounting for Income Taxes which amends ASC 740, Income Taxes (“ASC 740”) In August 2020, the FASB issued Accounting Standards Update 2020-06, Debt — Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging — Contracts in Entity’s Own Equity (Subtopic 815-40)	Note 2. Summary of Significant Accounting Policies Basis of Presentation The accompanying consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”). During fiscal year 2018, the Company presents financial information for the Practice for the period from January 1, 2018 through September 19, 2018 (“Predecessor Period”) and for the Company for the period from September 20, 2018 through December 31, 2018 (“Successor Period”). Principles of Consolidation The accompanying consolidated financial statements include the accounts of TOI Parent, its subsidiaries, all of which are controlled by TOI Parent through majority voting control, and a variable interest entity (“VIE”) for which TOI Parent (through TOI Management) is the primary beneficiary. The Company consolidates entities in which it has a controlling financial interest based on either the variable interest entity or voting interest model. All significant intercompany balances and transactions have been eliminated in consolidation. Variable Interest Entities The Company consolidates entities for which it has a variable interest and is determined to be the primary beneficiary. Noncontrolling interests in less-than-wholly-owned consolidated subsidiaries of the Company are presented as a component of total equity to distinguish between the interests of the Company and the interests of the noncontrolling owners. Revenues, expenses, and net income from these subsidiaries are included in the consolidated amounts as presented on the consolidated statements of operations. The Company holds a variable interest in the Practice as a result of entering into a master services agreement (“MSA”) in conjunction with the acquisition in September of 2018. As a result of the acquisition, HHHC is now a wholly-owned subsidiary of TOI Parent, the Practice is now a VIE of TOI Parent, as discussed in Note 17, and the Practice shareholders own a minority of the issued and outstanding common shares of the Company. Business Combinations The Company accounts for all transactions that represent business combinations using the acquisition method of accounting under Accounting Standards Codification Topic No. 805, Business Combinations Segment Reporting The Company presents the financial statements by segment in accordance with Accounting Standard Codification Topic No. 280, Segment Reporting Use of Estimates The preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates under different assumptions or conditions. Significant items subject to such estimates and assumptions include estimated accounts receivable, useful lives and recoverability of long-lived and intangible assets, recoverability of goodwill, fair values of acquired assets and assumed liabilities in business combinations, fair value of goodwill, fair value of share-based compensation, judgements related to revenue recognition, and deferred income taxes. Net Loss Per Share The Company has not issued substantive common shares since inception. The Company’s Series A Preferred Shares are considered as in-substance common stock as the net loss of the Company is attributable to the Series A Preferred shareholders, and therefore, they are included in the denominator to calculate net loss per share. Basic net loss per share is calculated by dividing net loss attributable to TOI Parent, Inc. by the weighted average Series A Preferred Shares, on an as-converted basis (see Note 19), and common shares issued and outstanding during the period. Diluted net income (loss) per share is calculated by dividing net income (loss) by the weighted-average number of Series A Preferred Shares and common shares used in the basic income (loss) per share calculation plus the number of potential common shares that would be issued assuming exercise of all potentially dilutive instruments. Potentially dilutive instruments are excluded from the calculation of diluted income (loss) per share if the effect of including such instruments is anti- dilutive. Given the Company incurred a net loss in each period presented, the stock options outstanding during each period are anti-dilutive. As such, diluted net loss per share is the same as basic net loss per share for each period presented. Revenue Recognition The Company follows the accounting requirements of Accounting Standard Codification Topic No. 606, Revenue from Contracts with Customers 1. Identification of the contract, or contracts, with a customer. 2. Identification of the performance obligations in the contract. 3. Determination of the transaction price. 4. Allocation of the transaction price to the performance obligations in the contract. 5. Recognition of revenue when, or as, we satisfy a performance obligation. The Company receives payments from the following sources for services rendered: (i) commercial insurers; (ii) the federal government under the Medicare program administered by the Centers for Medicare and Medicaid Services (“CMS”); (iii) state governments under the Medicaid and other programs; (iv) other third-party payors (e.g., hospitals and independent practice associations [“IPAs”]); and (v) individual patients and clients. Revenue primarily consists of capitation revenue, fee-for-service (“FFS”) revenue, dispensary revenue, and clinical trials revenue. Revenue is recognized in the period in which services are rendered or the period in which the Company is obligated to provide services. The form of billing and related risk of collection for such services may vary by type of revenue and the payor. The following paragraphs provide a summary of the principal forms of the Company’s billing arrangements and how revenue is recognized for each. Capitation Capitation revenues of the Company consist primarily of fees for medical services provided to patients by the Company under a capitated arrangement with various managed care organizations. Capitation revenue is paid monthly to the Company based on the number of enrollees assigned to the Company by the contracted managed care organization (per member, per month; or “PMPM”). Capitation contracts generally have a legal term of one year or longer. Capitation contracts have a single performance obligation that is a stand ready obligation to perform healthcare services to the population of enrolled members and constitutes a series for the provision of managed healthcare services for the term of the contract, which is deemed to be one month since the mix of patient-customers can and do change month over month. The transaction price for capitation contracts is variable as it primarily includes PMPM fees associated with unspecified membership that fluctuates throughout the contract. The Company generally estimates the transaction price using the most likely methodology and amounts are only included in the transaction price to the extent that it is probable that a significant reversal of cumulative revenue will not occur once any uncertainty is resolved. Certain contracts include terms for a capitation deduction where the cost of out-of-network referrals of members by the Company are deducted from the future payment. The deductions vary depending on the payor and are often not known until a future period. As such, the Company adjusts the transaction price for capitation deductions based on historic experience such that the amount of capitation revenue is constrained to the extent that it is not probable a significant reversal of revenue will occur in the future. Revenue is recognized in the month services are rendered on the basis of the transaction price established at that time. If subsequent information resolves uncertainties related to the transaction price, adjustments will be recognized in the period they are resolved. When payment has been received but services have not yet been rendered, the payment is recognized as a contract liability. Fee-for-Service Revenue FFS revenue represents revenue earned under contracts in which the Company bills and collects for medical services rendered by the Company’s employed physicians. The terms for FFS contracts are short in duration and only last for the period over which services are rendered (typically, one day). FFS revenue consists of fees for medical services provided to patients. These medical services are distinct since the patient can benefit from the medical services on their own. Each service constitutes a single performance obligation for which the patient accepts and receives the benefit of the medical services as they are performed. Under the FFS arrangements, the Company bills third-party payors and patients for patient care services provided and receives payment. Payments for services provided are generally less than billed charges. The Company records revenue net of an allowance for contractual adjustments, which represents the net revenue expected to collected from third-party payors (including managed care, commercial, and governmental payors such as Medicare and Medicaid), and patients. These expected collections are based on fees and negotiated payment rates in the case of third-party payors, the specific benefits provided for under each patient’s healthcare plans, mandated payment rates in the case of Medicare and Medicaid programs, and historical cash collections (net of recoveries). The transaction price from FFS arrangements is variable in nature because fees are based on patient encounters, credits due to patients, and reimbursement of provider costs, all of which can vary from period to period. The Company estimates the transaction price using the most likely methodology and amounts are only included in the net transaction price to the extent that it is probable that a significant reversal of cumulative revenue will not occur once any uncertainty is resolved. As a practical expedient, the Company adopted a portfolio approach to determine the transaction price for the medical services provided under FFS arrangements. Under this approach, the Company bifurcated the types of services provided and grouped health plans with similar fees and negotiated payment rates. At these levels, portfolios share the characteristics conducive to ensuring that the results do not materially differ from the standard applied to individual patient contracts related to each medical service provided. The recognition of net revenue (gross charges less contractual allowances) from such services is dependent on such factors as proper completion of medical charts following a patient visit, the forwarding of such charts to the Company’s billing center for medical coding and entering into the Company’s billing system, and the verification of each patient’s submission or representation at the time services are rendered as to the payor(s) responsible for payment of such services. Revenue is recorded on the date the services are rendered based on the information known at the time of entering of such information into the Company’s billing systems as well as an estimate of the revenue associated with medical services. When the performance obligation is not satisfied, the billing is recognized as a contract liability. Dispensary The Company sells oral prescription drugs directly through its dispensaries. Each prescription filled and delivered to the customer is a distinct performance obligation. The transaction price for the prescriptions is based on fee schedules set by various pharmacy benefit managers (“PBMs”) and other third party payors. The fee schedule is often subject to direct and indirect remuneration (“DIR”) fees, which are based primarily on pre-established metrics. DIR fees may be assessed in periods after payments are received against future payments. The Company estimates DIR fees to arrive at the transaction price for prescriptions. The Company recognizes revenue based on the transaction at the time the customer takes possession of the oral drug. Clinical Trials Revenue The Company enters into contracts to perform clinical research trials. The terms for clinical trial contracts last many months as the clinical research is performed. Each contract represents a single, integrated set of research activities and thus is a single performance obligation. The performance obligation is satisfied over time as the output is captured in data and documentation that is available for the customer to consume over the course of arrangement and furthers progress of the clinical trial. Under the clinical trial contracts, the Company receives a fixed payment for administrative, set-up, and close-down fees; a fixed amount for each patient site visit; and certain expense reimbursements. Under ASC 606, the Company has elected to recognize revenue for these arrangements using the ‘as-invoiced’ practical expedient. The Company invoices the customer periodically based on the progress of the trial such that each invoice captures the revenue earned to date based on the state of the trial as established between the Company and the customer. Direct Costs of Sales Direct cost of sales primarily consists of wages paid to clinical personnel and other health professionals, oral and IV drug costs, and other medical supplies used to provide patient care. The Company’s costs for clinical personnel wages are expensed as incurred and the Company’s costs for inventory and medical supplies are expensed when used, generally by applying the specific identification method. Cash Cash consists of deposits with banking institutions. The carrying value of the Company’s cash approximates fair value due to the short-term maturity of these instruments (less than three months). Accounts Receivable The Company accounts for accounts receivable under Accounting Standard Codification Topic No. 310, Receivables For third-party payors including Medicare, Medicaid, managed care providers, and commercial payors, the collectable amount is based on the estimated contractual reimbursement percentage, which is based on current contract prices or historical paid claims data by payor. For self-pay accounts receivable, which includes patients who are uninsured and the patient responsibility portion for patients with insurance, the collectable amount is determined using estimates of historical collection experience without regard to aging category.These estimates are adjusted for estimated conversions of patient responsibility portions, expected recoveries, and any anticipated changes in trends. Accounts receivable can be impacted by the effectiveness of the Company’s collection efforts.Additionally, significant changes in payor mix, business office operations, economic conditions, or trends in federal and state governmental healthcare coverage could affect the collectable amount of accounts receivable. The Company maintains reserves for potential credit losses on accounts receivable. Management reviews the composition of accounts receivable and analyzes historical bad debts, customer concentrations,customer credit worthiness, current economic trends, and changes in customer payment patterns to evaluate the adequacy of these reserves. The Company also regularly analyzes the ultimate collectability of accounts receivable after certain stages of the collection cycle using a look-back analysis to determine the amount of receivables subsequently collected, and adjustments are recorded when necessary. The Company continuously monitors its collections of receivables and its policy is to write off receivables when they are determined to be uncollectible. As of December 31, 2020 and 2019, the Company does not have an allowance for doubtful accounts. Inventories The Company accounts for inventory under Accounting Standard Codification Topic No. 330, Inventory The Company receives purchase discounts on products purchased. Contractual arrangements with vendors, including manufacturers and wholesalers, normally provide for the Company to receive purchase discounts from established list prices in one, or a combination, of the following forms: (i) a direct discount at the time of purchase or (ii) a discount for the prompt payment of invoices. Additionally, in other circumstances, the Company may receive rebates when products are purchased indirectly from a manufacturer (e.g., through a wholesaler). These rebates are recognized when intravenous chemotherapy drugs and oral prescription drugs are dispensed and are generally calculated by manufacturers within 30 days after the end of each completed quarter. The Company also receives additional rebate under its wholesaler contracts if it exceeds contractually defined annual purchase volumes. Purchase rebates are recorded as reductions to cost of services. Property and Equipment, net The Company accounts for property and equipment under Accounting Standard Codification Topic No. 360, Property, Plant, and Equipment When events or changes in circumstances indicate that the carrying amount of long-lived assets, including property and equipment, or other long-lived assets, may not be recoverable, an evaluation of the recoverability of currently recorded costs is performed. When an evaluation is performed, the estimated value of undiscounted future net cash flows associated with the asset groups is compared to the asset groups’ carrying value to determine if a write-down to fair value is required. If such assets are considered to be impaired, the impairment to be recognized is measured as the amount by which the carrying amount of the asset group exceeds the fair value of the assets. There were no impairment adjustments recorded for long- lived assets during the years ended December 31, 2020, 2019, the Successor Predecessor Accounts Payable, Accrued Expenses, and Other Current Liabilities Accounts payable primarily consists of unpaid invoices related to routine operating expenses. Accrued expenses and other current liabilities primarily consist of accruals made for payroll expenses, deferred capitation, and FFS revenue. Leases Lease agreements are evaluated to determine whether they are capital or operating leases in accordance with Accounting Standards Codification, Topic No. 840, Leases Goodwill and Intangible Assets The Company accounts for goodwill and intangible assets under Accounting Standards Codification Topic No. 350, Goodwill and Other Goodwill is not amortized but is required to be evaluated for impairment at the same time every year. The Company performs its annual testing of impairment for goodwill in the fourth quarter of each year. When impairment indicators are identified, the Company compares the reporting unit’s fair value to its carrying amount, including goodwill. An impairment loss is recognized as the difference, if any, between the reporting unit’s carrying amount and its fair value to the extent the difference does not exceed the total amount of goodwill allocated to the reporting unit. The Company performed a qualitative analysis and determined that no indicators of impairment existed at December 31, 2020 and 2019 and therefore, there was no goodwill impairment charge during the years ended December 31, 2020, 2019, and the Successor Period, as a result of the Company’s annual impairment evaluation. Under ASC 350, finite-lived intangible assets are stated at acquisition-date fair value. Intangible assets are amortized using the straight-line method. Finite-lived intangible assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. When circumstances indicate that recoverability may be impaired, the Company assesses its ability to recover the carrying value of the asset group from the expected future pre-tax cash flows (undiscounted and without interest charges) of the related operations. If these cash flows are less than the carrying value of such asset, an impairment loss is recognized for the difference between estimated fair value and carrying value. Fair value is determined based on appropriate valuation techniques. The Company performed a qualitative analysis and determined that there were no indicators of impairment of its finite-lived intangible assets during the years ended December 31, 2020, 2019, and the Successor Period. Debt The Company accounts for debt net of debt issuance costs. Debt issuance costs are capitalized, netted against the related debt for presentation purposes, and amortized to interest expense over the terms of the related debt using the effective interest method. Income Taxes The Company accounts for income taxes under the asset and liability method under Accounting Standards Codification Topic No. 740, Income Taxes Share-Based Compensation Plan The Company accounts for share-based compensation under Accounting Standards Codification Topic No. 718, Stock Based Compensation Excess tax benefits of awards related to stock option exercises are recognized as an income tax benefit in the statement of operations and reflected in operating activities in the statement of cash flows. Commitments and Contingencies The Company accounts for contingent liabilities under Accounting Standards Codification Subtopic No. 450-20, Contingencies Fair Value Measurements The Company accounts for fair value measurements under Accounting Standards Codification Topic No. 820, Fair Value Measurements ● Level 1 inputs: Unadjusted quoted prices in active markets for identical assets or liabilities accessible to the reporting entity at the measurement date. ● Level 2 inputs: Other than quoted prices included in Level 1 inputs that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the asset or liability. ● Level 3 inputs: Unobservable inputs for the asset or liability used to measure fair value to the extent that observable inputs are not available, thereby allowing for situations in which there is little, if any, market activity for the asset or liability at measurement date.

Significant Risks and Uncertainties Including Business and Credit Concentrations
Significant Risks and Uncertainties Including Business and Credit Concentrations	Note 3. Significant Risks and Uncertainties Including Business and Credit Concentrations Interest Rate Risk The London Interbank Offered Rate (“LIBOR”) may be eliminated in the near future. It is expected that a number of banks currently reporting information used to set LIBOR will stop doing so at the end of 2021 when their reporting commitments end. This will either end the publication of LIBOR immediately or degrade its quality such that it would no longer be a relevant metric to the Company. Change in LIBOR could affect the interest rates of the revolving credit facility and unsecured note payable. If LIBOR is no longer available, the Company will pursue alternative interest rate calculations in its revolving credit facility and unsecured note payable. However, if no alternative can be determined, the LIBOR rate component will no longer be used in determining the rates. As of September 30, 2021 and December 31, 2020, the potential effect of no longer using the LIBOR rate component to the Company’s interest rates would not have had a material effect on the interest rate in the credit facility or the note, thus the discontinuation of LIBOR is not expected to have a material effect on the Company’s financial statements. Credit Risk Financial instruments that potentially subject the Company to concentrations of credit risk consist primarily of cash and accounts receivable. Cash accounts in a financial institution may, at times, exceed the Federal Deposit Insurance Corporation (“FDIC”) coverage of $250,000 per account. The Company has not experienced losses on these accounts, and management believes the Company is not exposed to significant risks on such accounts. The Company’s accounts receivable has implicit collection risk. The Company grants credit without collateral to their patients, most of whom are local residents and are insured under third-party payor agreements. The Company believes this risk is partially mitigated by the Company’s establishment of long-term agreements and relationships with third-party payors that provide the Company with insight into historic collectability and improve the collections process. Revenue Concentration Risk The concentration of net revenue on a percentage basis for major payors at September 30, 2021 and 2020 are as follows: Nine Months Ended September 30, 2021 2020 Percentage of net revenue: Payor A 17 % 15 % Payor B 14 % 15 % The concentration of gross receivables on a percentage basis for major payors at September 30, 2021 and December 31, 2020 are as follows: September 30, December 31, 2021 2020 Percentage of gross receivables: Payor B 21 % 11 % Payor D 22 % 21 % All of the Company’s revenue is generated from customers located in the United States. Vendor Concentration Risk The concentration of cost of sales on a percentage basis for major vendors at September 30, 2021 and 2020 are as follows: Nine Months Ended September 30, 2021 2020 Percentage of cost of sales: Vendor A 51 % 54 % Vendor B 48 % 44 % The concentration of gross payables on a percentage basis for major vendors at September 30, 2021 and December 31, 2020 are as follows: September 30, December 31, 2021 2020 Percentage of gross payables: Vendor A 30 % 42 % Vendor B 59 % 48 % COVID-19 Pandemic In January 2020, the Secretary of the U.S. Department of Health and Human Services (“HHS”) declared a national public health emergency due to a novel strain of coronavirus (“COVID-19”). In March 2020, the World Health Organization declared the outbreak of COVID-19, a disease caused by this coronavirus, a pandemic. The resulting measures to contain the spread and impact of COVID-19 and other developments related to COVID-19 affected the Company’s results of operations during 2020. Where applicable, the impact resulting from the COVID-19 pandemic during the nine months ended September 30, 2021, has been considered, including updated assessments of the recoverability of assets and evaluation of potential credit losses. As a result of the COVID-19 pandemic, federal and state governments have passed legislation, promulgated regulations, and taken other administrative actions intended to assist healthcare providers in providing care to COVID-19 and other patients during the public health emergency. Sources of relief include the Coronavirus Aid, Relief and Economic Security Act (the “CARES Act”), which was enacted on March 27, 2020, the Paycheck Protection Program and Health Care Enhancement Act (the “PPPHCE Act”), which was enacted on April 24, 2020, and the Consolidated Appropriations Act, 2021 (the “CAA”), which was enacted on December 27, 2020. In total, the CARES Act, PPPHCE Act, and the CAA authorize $178 billion in funding to be distributed to hospitals and other healthcare providers through the Public Health and Social Services Emergency Fund (the “PHSSEF”). In addition, the CARES Act provides for an expansion of the Medicare Accelerated and Advance Payment Program whereby inpatient acute care hospitals and other eligible providers were able to request accelerated payment of up to 100% of their Medicare payment amount for a six-month period to be repaid through withholding of future Medicare fee-for-service payments. Various other state and local programs also exist to provide relief, either independently or through distribution of monies received via the CARES Act. During the nine months ended September 30, 2021 and the year ended December 31, 2020, the Company was a beneficiary of these stimulus measures. The Company received $4,992,758 in Paycheck Protection Program (“PPP”) loans under the CARES Act. PPP loans may be eligible for forgiveness if the funds were used for eligible payroll costs, payments on business mortgage interest payments, rent, or utilities during either the 8- or 24-week period after disbursement (see Note 11). The Company has elected to account for the loans as current debt until such loans are forgiven. Forgiveness was received during the nine months ended September 30, 2021, and as such, the Company recognized the loan principal balance and accrued interest as a gain on debt extinguishment in the condensed consolidated income statements. The Company received $2,726,856 from CMS under the Accelerated and Advance Payment Program which is an advance on future Medicare payments and will be recouped from future payments due to the Company by Medicare after 120 days. Effective October 1, 2020, the program was amended such that providers are required to repay accelerated payments beginning one year after the payment was issued. After such one-year period, Medicare payments owed to providers will be recouped against Medicare payments according to the repayment terms. As of September 30, 2021 and December 31, 2020, the Medicare accelerated payments are reflected within accrued expenses and other current liabilities in the consolidated balance sheets. The $2,726,856 is expected to be fully recouped by the first quarter of 2022. The Company received funding from United States Department of HHS as part of the Provider Relief Funding under the CARES Act. Provider Relief Funding is paid in the form of a grant and does not require repayment if used to cover lost revenue, as defined, attributable to COVID-19 and healthcare-related expenses, as defined, including qualifying direct labor, paid or purchased to prevent, prepare for, and respond to COVID-19. Under International Accounting Standard 20, Accounting for Government Grants	Note 3. Significant Risks and Uncertainties Including Business and Credit Concentrations Interest Rate Risk The London Interbank Offered Rate (LIBOR) may be discontinued in quality in the near future. It is expected that a number of banks currently reporting information used to set LIBOR will stop doing so at the end of 2021 when their reporting commitments end. This will either end the publication of LIBOR immediately or degrade its quality such that it would no longer be a relevant metric to the Company. Change in LIBOR could affect the interest rates of the revolving credit facility and unsecured note payable. If LIBOR is no longer available, the Company will pursue alternative interest rate calculations in its revolving credit facility and unsecured note payable. However, if no alternative can be determined, the LIBOR rate component will no longer be used in determining the rates. As of December 31, 2020, the potential effect of no longer using the LIBOR rate component to the Company’s interest rates would not have had a material effect on the interest rate in the credit facility or the note, thus the discontinuation of LIBOR is not expected to have a material effect on the Company’s financial statements. Credit Risk Financial instruments that potentially subject the Company to concentrations of credit risk consist primarily of cash and accounts receivable. Cash accounts in a financial institution may, at times, exceed the Federal Deposit Insurance Corporation (“FDIC”) coverage of $250,000 per account. The Company has not experienced losses on these accounts, and management believes the Company is not exposed to significant risks on such accounts. The Company’s accounts receivable has implicit collection risk. The Company grants credit without collateral to their patients, most of whom are local residents and are insured under third-party payor agreements. The Company believes this risk is partially mitigated by the Company’s establishment of long-term agreements and relationships with third-party payors that provide the Company with insight into historic collectability and improve the collections process. Revenue Concentration Risk The concentration of net revenue on a percentage basis for major payors at December 31, 2020, 2019 and period from September 20, 2018 through December 31, 2018 and period from January 1, 2018 through September 19, 2018 are as follows: Period from Period from September 20, January 1, Year Ended Year Ended 2018 through 2018 through December 31, December 31, December 31, September 19, 2020 2019 2018 2018 Successor Predecessor Percentage of Net Revenue: Payor A 15 % 18 % 23 % 20 % Payor B 15 % 16 % 13 % 11 % Payor C 7 % 11 % 11 % 11 % Payor D 9 % 11 % 9 % 8 % The concentration of gross receivables on a percentage basis for major payors at December 31, 2020 and 2019 are as follows: December 31, December 31, 2020 2019 Percentage of Gross Receivables: Payor A 1 % 3 % Payor B 11 % 24 % Payor C 3 % 6 % Payor D 21 % 26 % All of the Company’s revenue is generated from Customers located in the United States. Vendor Concentration Risk The concentration of cost of sales on a percentage basis for major vendors at December 31, 2020, 2019 and period from September 20, 2018 through December 31, 2018 and period from January 1, 2018 through September 19, 2018 are as follows: Period from Period from September 20, January 1, Year Ended Year Ended 2018 through 2018 through December 31, December 31, December 31, September 19, 2020 2019 2018 2018 Successor Predecessor Percentage of Cost of Sales: Vendor A 55 % 57 % 46 % 48 % Vendor B 45 % 43 % 52 % 50 % The concentration of gross payables on a percentage basis for major vendors at December 31, 2020 and 2019 are as follows: December 31, December 31, 2020 2019 Percentage of Gross Payables: Vendor B 48 % 49 % Vendor A 42 % 39 % All others 10 % 12 % COVID-19 Pandemic In January 2020, the Secretary of the U.S. Department of Health and Human Services (“HHS”) declared a national public health emergency due to a novel strain of coronavirus (“COVID-19”). In March 2020, the World Health Organization declared the outbreak of COVID-19, a disease caused by this coronavirus, a pandemic. The resulting measures to contain the spread and impact of COVID-19 and other developments related to COVID-19 have affected the Company’s results of operations during 2020. Where applicable, the impact resulting from the COVID-19 pandemic during the year ended December 31, 2020, has been considered, including updated assessments of the recoverability of assets and evaluation of potential credit losses. As a result of the COVID-19 pandemic, federal and state governments have passed legislation, promulgated regulations, and taken other administrative actions intended to assist healthcare providers in providing care to COVID-19 and other patients during the public health emergency. Sources of relief include the Coronavirus Aid, Relief and Economic Security Act (the “CARES Act”), which was enacted on March 27, 2020, the Paycheck Protection Program and Health Care Enhancement Act (the “PPPHCE Act”), which was enacted on April 24, 2020, and the Consolidated Appropriations Act, 2021 (the “CAA”), which was enacted on December 27, 2020. In total, the CARES Act, PPPHCE Act and the CAA authorize The Company received $4,992,758 in Paycheck Protection Program (“PPP”) loans under the CARES Act. PPP loans may be eligible for forgiveness if the funds were used for eligible payroll costs, payments on business mortgage interest payments, rent, or utilities during either the 8- or 24-week period after disbursement (see Note 11). The Company has elected to account for the loans as current debt until such loans are forgiven. The Company received $2,726,856 from CMS under the Accelerated and Advance Payment Program which is an advance on future Medicare payments and will be recouped from future payments due to the Company by Medicare after 120 days. Effective October 1, 2020, the program was amended such that providers are required to repay accelerated payments beginning one year after the payment was issued. After such one-year period, Medicare payments owed to providers will be recouped against Medicare payments according to the repayment terms. As of December 31, 2020, the entire $2.4 million of Medicare accelerated payments are reflected within accrued expenses and other current liabilities in the consolidated balance sheet. The Company expects the $2,726,856 will be fully recouped during 2021. The Company received $978,150 from United States Department of HHS as part of the Provider Relief Funding under the CARES Act. Provider Relief Funding is paid in the form of a grant and does not require repayment if used to cover lost revenue, as defined, attributable to COVID-19 and healthcare- related expenses, as defined, including qualifying direct labor, paid or purchased to prevent, prepare for, and respond to COVID-19.

The Company uses inputs such as actual trade data, quoted market prices from dealers or brokers, and other similar sources to determine the fair value of its investments. The fair value of Public Warrants issued in connection with the Initial Public Offering are measured based on the listed market price of such warrants, a quoted price in an active market, a Level 1 measurement. The fair value of the Private Placement Warrants has been estimated using a Monte Carlo simulation model each measurement date. For the three months and nine months ended September 30, 2021, the Company recognized a gain resulting from a decrease in the fair value of the derivative warrant liabilities of approximately $1.1 For the three and nine months ended September 30, 2020, the Company recognized a loss of approximately $2.3 million and approximately $5.2 The estimated fair value of the Private Placement Warrants is determined using Level 3 inputs. Inherent in a Monte Carlo simulation are assumptions related to expected stock-price volatility, expected life, risk-free interest rate and dividend yield. The Company estimates the volatility of its common stock based on historical volatility of select peer companies that matches the expected remaining life of the warrants. The risk-free interest rate is based on the U.S. Treasury zero-coupon yield curve on the grant date for a 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 remaining at zero.

The fair value of the Public Warrants issued in connection with the Public Offering and Private Placement Warrants were initially measured at fair value using a Monte Carlo simulation model and subsequently, the fair value of the Private Placement Warrants have been estimated using a Monte Carlo simulation model each measurement date. The fair value of Public Warrants issued in connection with the Initial Public Offering have been measured based on the listed market price of such warrants, a Level 1 measurement, beginning in June 2020. The estimated fair value of the Private Placement Warrants, and the Public Warrants prior to being separately listed and traded, is determined using Level 3 inputs. Inherent in a Monte Carlo simulation are assumptions related to expected stock-price volatility, expected life, risk-free interest rate and dividend yield. The Company estimates the volatility of its Class A common stock warrants based on implied volatility from the Company’s traded warrants and from historical volatility of select peer company’s Class A common stock that matches the expected remaining life of the warrants. The risk-free interest rate is based on the U.S. Treasury zero-coupon yield curve on the grant date for a 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 remaining at zero.

The maturity date of the loan is May 2, 2022. On May 13, 2020, the Company entered into a Paycheck Protection Program (“PPP”) loan with Celtic Bank Corporation in the amount of $2,000,000, with interest bearing at 1%. The maturity date of the loan is May 13, 2022. The Company recorded a PPP loan as a result of the acquisition of TOI FL on February 12, 2021 with Valley National Bank in the amount of $149,398, with interest bearing at 1%. The maturity date of the loan is May 4, 2022. The application for the PPP and SBA funds required the Company to, in good faith, certify that the current economic uncertainty made the loan request necessary to support the ongoing operations of the Company. This certification further required the Company to take into account its current business activity and its ability to access other sources of liquidity sufficient to support ongoing operations in a manner that is not significantly detrimental to the business. The receipt of these funds, and the forgiveness of the loan attendant to these funds, is dependent on the Company having initially qualified for the loan and qualifying for the forgiveness of such loan based on its future adherence to the forgiveness criteria. Management has performed an assessment and concluded they met the eligibility requirements to participate in the PPP and SBA programs and it is probable they will qualify for forgiveness, as determined by the program administrators within the parameters of the program. The loan proceeds were used to pay for qualifying salaries and were recognized to other revenues in 2020 as qualified expenses were paid. The Company applied for loan forgiveness in December 2020 for the PPP loan and in March 2021 for the SBA loan. Through the TOI FL acquisition, the Company recorded a PPP loan (and corresponding escrow receivable) for which the application for forgiveness was being processed. During the nine months ended September 30, 2021, the Company received notice of forgiveness for each of the PPP and SBA loans. Upon receiving forgiveness, the Company recognized the loan principal balance and accrued interest as a gain on debt extinguishment, with a corresponding write off of the escrow receivable, in the condensed consolidated statements of operation during the nine months ended September 30, 2021. On February 26, 2020 the Company entered into a credit agreement with MUFG Union Bank (“Credit Agreement”), which allows the Company to borrow up to an aggregate principal amount of $10,000,000 in the form of term loans, revolving credit commitments (“Revolver”), and a letter of credit (“LOC”) facility. The term loans and the Revolver shall bear interest at base rate plus the applicable margin or LIBOR rate plus the applicable margin. The Company can prepay the obligations at their option or upon the occurrence of certain events. The outstanding principal on the term loans will be repaid in quarterly installments equal to (i) $93,750 on the last business day of each quarter ending December 31, 2023, commencing on June 30, 2020 and (ii) $187,500 on the last business day of each quarter thereafter. The maturity date of the Credit Agreement is February 26, 2025. As of September 30, 2021, the Company has borrowed $5,125,000 in the form of a term loan. The Company paid down $2,500,000 drawn upon the Revolver in the second quarter, and no additional amounts were drawn during the current quarter. As of March 31, 2021 and December 31, 2020, the Company violated certain covenants in the Credit Agreement. On June 18, 2021, the Company entered into an amendment to the Credit Agreement, which reduced the aggregate principal amount from which the Company can borrow to $9,000,000 and concurrently provided a waiver for the covenant violations. As part of the amendment, the Company paid $2,000,000 of the outstanding principal balance on the term loan and no additional principal payments are required until the quarter ending March 31, 2022. The Company determined that the amendment to the Credit Agreement meet the definition of a debt modification under ASC 470-50, Modifications and Extinguishments Net debt issuance costs are presented as a direct reduction in the condensed consolidated balance sheets and amount to $229,725 from current debt and $282,512 from long-term debt as of September 30, 2021 and December 31, 2020, respectively. The amortization of the debt issuance costs was charged to interest expense for all periods presented. The amount of debt issuance costs included in interest expense for the nine months ended September 30, 2021 and September 30, 2020 was approximately $52,787 and $41,950, respectively. The Company paid interest of $193,096 and $168,530 on the Credit Agreement term loan for the nine months ended September 30, 2021 and 2020, respectively.	Note 11.

The maturity date of the loan is May 2, 2022. On May 13, 2020, the Company entered into a Paycheck Protection Program (“PPP”) loan with Celtic Bank Corporation in the amount of $2,000,000, with interest bearing at 1%. The maturity date of the loan is May 13, 2022. The Company has classified the PPP and SBA loans above entirely as current liabilities as the majority of payments will occur throughout 2021. The application for the PPP and SBA funds required the Company to, in good faith, certify that the current economic uncertainty made the loan request necessary to support the ongoing operations of the Company. This certification further required the Company to take into account its current business activity and its ability to access other sources of liquidity sufficient to support ongoing operations in a manner that is not significantly detrimental to the business. The receipt of these funds, and the forgiveness of the loan attendant to these funds, is dependent on the Company having initially qualified for the loan and qualifying for the forgiveness of such loan based on its future adherence to the forgiveness criteria.Management has performed an assessment and concluded they met the eligibility requirements to participate in the PPP and SBA programs and it is probable they will qualify for forgiveness, as determined by the program administrators within the parameters of the program. The loan proceeds were used to pay for qualifying salaries in 2020 as qualified expenses were paid. The Company applied for forgiveness in December 2020 for the PPP loan and in March 2021 for the SBA loan; however, the Company’s eligibility and qualified expenses are subject to audit by the SBA and although the Company anticipates it will qualify for forgiveness, the SBA may require the Company to repay all or a portion of the loan value recorded for the year ended December 31, 2020. While the Company believes that the PPP loan was properly obtained, there can be no assurance regarding the outcome of an SBA review. The Company applied for loan forgiveness in December 2020 for the PPP loan. On June 17, 2021, the Company received notice of forgiveness of the loan. On February 26, 2020 the Company entered into a credit agreement with MUFG Union Bank (“Credit Agreement”), which allows the Company to borrow up to an aggregate principal amount of $10 million in the form of term loans, revolving credit commitments (“Revolver”), and a letter of credit (“LOC”) facility. The term loans and the Revolver shall bear interest at base rate plus the applicable margin or LIBOR rate plus the applicable margin. The Company can prepay the obligations at their option or upon the occurrence of certain events. The outstanding principal on the term loans will be repaid in quarterly installments equal to (i) $93,750 on the last business day of each quarter ending December 31, 2023, commencing on June 30, 2020 and (ii) $187,500 on the last business day of each quarter thereafter. The maturity date of the Credit Agreement is February 26, 2025. As of December 31, 2020, the Company has borrowed $7,500,000 in the form of a term loan from the $10,000,000 availability of the Credit Agreement, leaving $2,500,000 available borrowings under the Credit Agreement. The Company violated the senior leverage ratio and fixed charge coverage ratio associated with the Credit Agreement’s variable rate term loan in 2020 and during 2021. On June 18, 2021, the Company entered into an amendment to the Credit Agreement which changed the covenants and concurrently received a waiver for the period ended December 31, 2020. Net debt issuance costs are presented as a direct reduction of the Company’s long-term debt in the consolidated balance sheets and amount to $282,512 and $0 as of December 31, 2020 and 2019, respectively. The amortization of the debt issuance costs was charged to interest expense for all periods presented. The amount of debt issuance costs included in interest expense for the years ended December 31, 2020 and 2019 was approximately $59,988 and $0, respectively. The aggregate maturities of long-term debt for each of the five years subsequent to December 31, 2020 are: $375,000 in 2021, 2022 , and 2023 , $750,000 in 2024, and $5,343,750 in 2025.

Income Taxes
Income Taxes		Note 11 — Income Taxes The Company’s taxable income primarily consists of interest income on the Trust Account, less any franchise taxes. The Company’s formation and operating costs are generally considered start-up costs and are not currently deductible. The income tax provision (benefit) for the year ended December 31, 2020 consists of the following: December 31, 2020 December 31, 2019 Current Federal $ 11,434 $ — State — — Deferred Federal (101,676) (483) State — — Valuation allowance 101,676 483 Income tax provision 11,434 — The provision for income taxes was deemed to be de minimis for the period from November 1, 2019 (inception) through December 31, 2019. The Company’s net deferred tax assets are as follows: December 31, 2020 December 31, 2019 Deferred tax assets: Start-up/Organization costs $ 101,676 $ 315 Net operating loss carryforwards — 168 Total deferred tax assets 101,676 483 Valuation allowance (101,676) (483) Deferred tax asset, net of allowance $ — $ — In assessing the realization of deferred tax assets, management considers whether it is more likely than not that some portion or all of the deferred tax assets will not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which temporary differences representing net future deductible amounts become deductible. Management considers the scheduled reversal of deferred tax assets, projected future taxable income and tax planning strategies in making this assessment. After consideration of all of the information available, management believes that significant uncertainty exists with respect to future realization of the deferred tax assets and has therefore established a full valuation allowance. For the year ended December 31, 2020 and for the period from November 1, 2019 (inception) to December 31, 2019, the valuation allowance was $101,676 $483 A reconciliation of the statutory federal income tax rate (benefit) to the Company’s effective tax rate is as follows: December 31, 2020 December 31, 2019 Statutory federal income tax $ (1,748,979) $ (483) Change in fair value of derivative warrant liabilities (1,450,150) — Financing costs - derivative warrant liabilities (2,503) — Change in valuation allowance 3,213,066 483 Income tax expense $ 11,434 $ — There were no unrecognized tax benefits as of December 31, 2020, and 2019. No amounts were accrued for the payment of interest and penalties as of December 31, 2020, and 2019. 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. The Company’s management does not expect that the total amount of unrecognized tax benefits will materially change over the next twelve months.

Income Taxes
Income Taxes	Note 12. Income Taxes The Company recorded income tax expense of $798,504 for the three months ended September 30, 2021, as compared to income tax benefit of $23,190 for the three months ended September 30, 2020. The increase of $821,694 in income tax expense is primarily related to the corresponding increase in our profitable entity’s, TOI Parent’s, pre-tax book income combined with an increase in our annual effective tax rate. Our effective tax rate decreased to (36.6)% for the three months ended September 30, 2021, from 3.3% for the three months ended September 30, 2020, primarily due to increase in the valuation allowance, partially offset by the tax effect of gain on PPP loan forgiveness, which is not taxable for federal income tax purposes. The Company recorded income tax expense of $1,796,123 for the nine months ended September 30, 2021, as compared to income tax benefit of $298,102 for the nine months ended September 30, 2020. The increase of $2,094,225 in income tax expense is primarily related to the corresponding increase in our profitable entity’s, TOI Parent’s, pre-tax book income combined with an increase in our effective tax rate. Our effective tax rate increased to 175.2% for the nine months ended September 30, 2021, from 3.3% for the nine months ended September 30, 2020, primarily due to increase in the valuation allowance, partially offset by the tax effect of gain on PPP loan forgiveness, which is not taxable for federal income tax purposes. Our effective tax rate for the three and nine months ended September 30, 2021, was different than the U.S. federal statutory tax rate of 21.0% primarily due to increase in the valuation allowance, partially offset by the tax effect of gain on PPP loan forgiveness, which is not taxable for federal income tax purposes.

The net change in the total valuation allowance was an increase of $3,596,998 in 2020 and an increase of $1,854,005 in 2019. The valuation allowance at December 31, 2020, was primarily related to net operating loss carryforwards of the Practice that, in the judgment of management, are not more likely than not to be realized. TOI Parent and the Practice file separate federal and state tax returns. Accordingly, net operating losses of the Practice cannot offset taxable income of TOI Parent. Deferred tax assets and deferred tax liabilities have been separately determined for TOI Parent and the Practice, as has the valuation allowance assessment for each. The table above reflects the combined deferred tax assets, deferred tax liabilities, and valuation allowance for both TOI Parent and the Practice. Of the $(5,451,003) total valuation allowance, $(4,801,222) is attributable to the Practice and $(649,781) is attributable to TOI Parent. The net deferred tax liabilities of $(1,612,769) is primarily attributable to TOI Parent, which is net of a $(649,781) valuation allowance. The Practice has total gross deferred tax assets of $4,922,056, most of which is reduced by a valuation allowance. In assessing the realizability of deferred tax assets, management considers whether it is more likely than not that some portion or all of the deferred tax assets will not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences become deductible. Management considers the scheduled reversal of deferred tax liabilities (including the effect of available carry back and carryforward periods), projected future taxable income, and tax-planning strategies in making this assessment. Based upon the level of historical taxable income and projections for future taxable income over the periods in which the deferred tax assets are deductible, management believes it is more likely than not that the Company will realize the benefits of these deductible differences, net of the existing valuation allowances at December 31, 2020. The amount of the deferred tax asset considered realizable, however, could be reduced in the near term if estimates of future taxable income during the carryforward period are reduced. At December 31, 2020, the Company has net operating loss carryforwards for Federal income tax purposes of $7,637,918, all attributable to the Practice, which are available to offset future Federal taxable income of the Practice indefinitely. The Company has net operating loss carryforwards for state income tax purposes of $8,424,443, most of which is attributable to the Practice, which will begin to expire after 2041. Pursuant to Internal Revenue Code Section 382, annual use of the Company’s net operating loss (“NOL”) carryforwards may be limited in the event a cumulative change in ownership of more than 50% occurs within a three-year period. The Company has not completed a Section 382 analysis, however, it is not aware of any transactions that would result in an ownership change under Section 382. Further, the Company’s direct shareholders have remained constant since its inception in 2018. A summary of the changes in the amount of unrecognized tax benefits (excluding interest and penalties) for 2020 and 2019 is as follows: December 31, December 31, 2020 2019 Beginning balance of unrecognized tax benefits $ 1,902,659 $ — Additions based on tax positions related to the current year — 1,902,659 Additions based on tax positions of prior years — — Reductions due to lapse of applicable statute of limitation — — Settlements — — Ending balance of unrecognized tax benefits $ 1,902,659 $ 1,902,659 The Company anticipates reversal of the above amount within the next 12 months upon amendment of the Company’s 2019 federal and state income tax returns. The Company recognizes interest and penalties related to unrecognized tax benefits in income tax expense. Due to the Company’s NOL position, no interest or penalties have been recognized with respect to unrecognized tax benefits, as such amounts are considered immaterial. The Company is subject to taxation in the U.S., California, and Arizona. As of December 31, 2020, the statute of limitations remains open for tax year 2018, 2019, and 2020. The Company has accounted for the changes in net operating loss carryovers as a result of the CARES Act. Other provisions of the CARES Act did not have a material impact on the Company’s financial statements as of December 31, 2020.

Common and Preferred Shares	Note 13. Common and Preferred Shares The Company issued Series A Preferred Shares under the Company’s original Certificate of Incorporation dated September 10, 2018 and the Company’s Shareholders’ Agreement dated September 19, 2018. The Certificate of Incorporation was amended and restated on September 14, 2018 (“Amendment I”) and again on November 6, 2020 (“Amendment II”). Per the original Certificate of Incorporation, the Company had authority to issue 30,000 shares, consisting of 20,000 common shares and 10,000 Series A Preferred Shares. The Company issued 10,000 shares of Series A Preferred Shares on September 10, 2018 at $0.001 par value per share. As a result of Amendment I to the Certificate of Incorporation, Series A Preferred shareholders were entitled to a return of capital on their shares prior to any declaration or payment of dividends to common shareholders. The original preferred return was equal to the number of shares held by the preferred shareholder multiplied by the price paid for such shares. In the event of liquidation, dissolution, or winding up of the operations of the Company, Series A Preferred shareholders had preferential liquidation rights compared to the common shareholders. As such, the preferred shareholders were entitled to full payment of the original preferred return before the remaining assets of the Company were to be distributed to common and preferred shareholders based on their pro-rata share of total outstanding securities. Holders of Series A Preferred Shares were granted one vote, per share, for all matters voted on by the common shareholders of the Company. Given the short duration and immaterial operations of the Company between the execution of Amendment I as compared to the Original Certificate of Incorporation, there was no material accounting impact to the Company’s financial statements resulting from the execution of Amendment I. As a result of Amendment II, the Company now has the authority to issue 420,000 shares consisting of 400,000 common shares and 20,000 Series A Preferred Shares. Additionally, each outstanding common share was split into 10 common shares. Amendment II resulted in an extinguishment of old Series A Preferred Shares under the original Certificate of Incorporation and a deemed authorization and issuance of new Series A Preferred Shares. As such, the Company recognized Series A Preferred Shares at fair value at the amendment date, with the difference between the fair value and carrying value being recognized in retained earnings. The fair value of the Series A Preferred Shares was derived using a combination of a an option pricing model (“OPM”) and common stock equivalent method (“CSE”) which are considered Level 2 and Level 3 inputs, respectively, in the fair value hierarchy. The assumptions used in the OPM and CSE models are provided in the following tables: Option-pricing method Valuation date 11/6/2020 Liquidity event date 12/31/2024 Time to liquidity 4.15 years Total equity value $ 82,000,000 Annual dividend rate for common stock 0.0 % Annualized volatility 40.0 % Risk-free rate (continuously compounding) 0.3 % Common-stock equivalent method Valuation date 11/6/2020 Liquidity event date 12/31/2024 Time to liquidity 4.15 years Total equity value $ 82,000,000 Value per common stock equivalent $ 562.06 Further, under Amendment II, cumulative dividends on Series A Preferred Shares will accrue, whether or not declared by the Board at a rate of 6% per year. The preferred shareholders are entitled to payment of all accrued but unpaid dividends prior to declaration or payment of dividends to common shareholders. As of September 30, 2021 and December 31, 2020, dividends in arrears were $9,547,569 and $6,883,835, respectively. In the event of liquidation, Series A Preferred shareholders are entitled to receive payment of assets before distribution to common shareholders. If the full preferential amount is unavailable, the Series A Preferred shareholders will share ratably in the distribution. Additionally, holders of Series A Preferred Shares now have 10 votes, per share, as of November 6, 2020, for all matters voted upon by the common shareholders of the Company and have the option to convert outstanding Series A Preferred Shares into common shares, at any point in time, by a factor of 1 The Series A Preferred shareholders control the vote of the Board through direct representation and can initiate a sale of the Company that may result in the Series A Preferred Shares being redeemed for cash. This potential event is deemed to be outside the control of the Company and therefore, the Series A Preferred Shares are accounted for as temporary equity. In the first quarter of 2021, TOI Parent executed an equity capital raise in separate transactions with 3 accredited investors. A total of 1,451 of the Company’s Series A Preferred Shares were purchased in exchange for $20,000,000 and are subject to the terms of Amendment II of the Certificate of Incorporation. There were 11,451 Series A Preferred Shares issued and outstanding outstanding	Note 13. Common and Preferred Shares The Company issued Series A Preferred Shares under the Company’s original Certificate of Incorporation dated September 10, 2018 and the Company’s Shareholders’ Agreement dated September 19, 2018.

There were 10,000 Series A Preferred Shares issued and outstanding at December 31, 2020, 2019, and 2018. As a result of Amendment I to the Certificate of Incorporation, Series A Preferred shareholders were entitled to a return of capital on their shares prior to any declaration or payment of dividends to common shareholders. The original preferred return was equal to the number of shares held by the preferred shareholder multiplied by the price paid for such shares.

Additionally, each outstanding common share was split into 10 common shares. Amendment II resulted in the addition of a conversion option which allows the preferred shareholders to convert the Series A Preferred Shares into common shares. In addition, under Amendment II, the preferred shareholders are entitled to 6% cumulative dividends. Therefore, Amendment II resulted in an extinguishment of old Series A Preferred Shares under the original Certificate of Incorporation and a deemed authorization and issuance of new Series A Preferred Shares. As such, the Company recognized Series A Preferred Shares at fair value at the amendment date, with the difference between the fair value and carrying value being recognized in retained earnings.

The preferred shareholders are entitled to payment of all accrued but unpaid dividends prior to declaration or payment of dividends to common shareholders. As dividends have not been declared no liability associated with the accrued dividends has been recognized by the Company. As of December 31, 2020, dividends in arrears were $6,883,835. In the event of liquidation, Series A Preferred shareholders are entitled to receive payment of assets before distribution to common shareholders. If the full preferential amount is unavailable, the Series A Preferred shareholders will share ratably in the distribution. Additionally, holders of Series A Preferred Shares now have 10 votes, per share, for all matters voted upon by the common shareholders of the Company and have the option to convert outstanding Series A Preferred Shares into common shares, at any point in time, by a factor of 1 -to-10. The Series A Preferred shareholders control the vote of the Board through direct representation and can initiate a sale of the Company that may result in the Series A Preferred Shares being redeemed for cash. This potential event is deemed to be outside the control of the Company and therefore, the Series A Preferred Shares are accounted for as temporary equity. As of December 31, 2020, there were 100 common shares outstanding as one option holder of the Company’s 2019 Non-Qualified Stock Option Plan exercised their option to purchase the Company’s common shares on September 12, 2020. The Company had no outstanding common shares as of December 31, 2019, and 2018. The Practice, the Predecessor entity, had 1,000 common shares outstanding as of September 19, 2018.

Share-based Compensation Arrangement by Share-based Payment Award
Share-Based Compensation	Note 14. Share-Based Compensation Non-Qualified Stock Option Plan On January 2, 2019, the Company issued and adopted the 2019 Non-Qualified Stock Option Plan (“the Plan”) to incentivize directors, consultants, advisors, and other key employees of the Company and its subsidiaries to continue their association by providing opportunities to participate in the ownership and further growth of the Company. The Plan provides for the grant of options (“the Stock Options”) to acquire common shares of the Company. The Company issued immaterial amounts of stock options to non-employees for the nine months ended September 30, 2021 and the year ended December 31, 2020. Stock Options are exercised from the pool of shares designated by the appropriate Committee of the Board of Directors. The grant-date fair value of each option award is estimated on the date of grant using the Black-Scholes-Merton option-pricing model. The grant date fair value of the service vesting and the performance vesting options is recognized as an expense over the requisite service period and upon the achievement of the performance condition deemed probable of being achieved, respectively. The exercise price of each Stock Option shall be determined by the Committee and may not be less than the fair market value of the common shares on the date of grant. Stock Options have 10-year terms, after which they expire and are no longer exercisable. The total number of common shares for which Stock Options may be granted under the Plan shall not exceed 13,640. The Plan was amended on November 6, 2020, pursuant to which the total number of common shares for which Stock Options may be granted under the Plan shall not exceed 15,640. At September 30, 2021, there were 399,900 common shares of the Company authorized and unissued. The weighted average assumptions used in the Black-Scholes-Merton option-pricing model for the 2021 Stock Options are provided in the following table: 9 Months Ended 09/30/2021 Valuation assumptions Expected dividend yield — % Expected volatility 38.6% and 40.2 % Risk-free interest rate 0.76% to 1.12 % Expected term (years) 7 Stock option activity during the periods indicated is as follows: Weighted Weighted average Aggregate Number average remaining intrinsic Stock options of shares exercise price contractual term value Balance at January 1, 2021 14,860 $ 497.95 Granted 2,023 630.00 Exercised — Forfeited (1,215) 504.38 Expired — Balance at September 30, 2021 15,668 514.50 8.31 — Vested options exercisable at September 30, 2021 2,578 $ 497.03 6.86 — In June, 2021 the Company and certain participants in the Plan entered into agreements to amend the terms of the Stock Options previously issued to the participant during Q1 and Q2 2021. The amendment primarily related to updating the exercise price, vesting conditions, and the number of Stock Options. The modification to the Stock Options resulted in immaterial incremental share-based compensation expense recorded in the Company’s statement of operations. Total share-based compensation expense for the nine months ended September 30, 2021 and September 30, 2020 was $152,617 and $112,669, respectively, and for the three months ended September 30, 2021 and September 30, 2020, share-based compensation expense was $59,678 and $36,343, respectively.

That cost is expected to be recognized over a weighted average period of 2.68 and 3.07 years for the 2021 and 2020 unrecognized compensation costs, respectively. At September 30, 2021 and September 30, 2020, there was $1,294,168 and $807,777, respectively, of unrecognized stock compensation related to the unvested performance Stock Options granted under the Plan that are expected to vest. The total fair value of common shares vested for the nine months ended September 30, 2021 and September 30, 2020 was $321,591 and $220,518, respectively, and for the three months ended September 30, 2021 and September 30, 2020, the fair value of common shares vested was $84,813 and $38,759, respectively. Restricted Stock Awards (“RSAs”) Additionally, Agajanian Holdings (“Holdings”), a holder of Series A Preferred Shares of the Company, enters into arrangements with physicians employed by TOI CA to issue RSAs which represent Series A Preferred Shares of the Company. The RSAs only have performance vesting requirements linked to the sale of the Company so long as the optionee remains continuously and actively employed by the Company’s subsidiaries through the vesting date. For the nine months ended September 30, 2021 and the year ended December 31, 2020, Holdings issued 0 and 188 RSAs, respectively. The optionee is not entitled to dividends or distributions from the Company, nor are they entitled to vote. Additionally, the RSA may not be sold, transferred, pledged, or assigned at any time.

The grant date fair value of the service vesting and the performance vesting options is recognized as an expense over the requisite service period and upon the achievement of the performance condition deemed probable of being achieved, respectively. The exercise price of each Stock Option shall be determined by the Committee and may not be less than the fair market value of the common shares on the date of grant. Stock Options have 7-year terms, after which they expire and are no longer exercisable. The total number of common shares for which Stock Options may be granted under the Plan shall not exceed 13,640.

Stock Options become vested upon fulfillment of either service vesting conditions, performance vesting conditions, or both, as determined by the award agreement entered into by the Company and optionee. The service vesting requirement states that: (i) 25% of the service vesting options shall vest on the first anniversary of the grant date and (ii) the remaining 75% shall vest on an equal monthly-basis, so long as the optionee has remained continuously employed by the Company from the date of the award through the fourth anniversary of the grant date. The performance vesting requirement states that Stock Options shall vest upon sale of the Company only if the optionee has been continuously employed by the Company or its subsidiaries from the grant date through the date of such sale of the Company. For the awards vesting based on service conditions only and that have a graded vesting schedule, the Company recognizes compensation expense for vested awards in earnings, net of actual forfeitures in the period they occur, on a straight-line basis over the requisite service period.

In addition, these holders will have “piggy-back” registration rights to include their securities in other registration statements filed by the Company. The Company will bear the expenses incurred in connection with the filing of any such registration statements. Underwriting Agreement The Company granted the underwriters a 45-day option to purchase up to 3,000,000 additional Units to cover any over-allotments, at the initial public offering price less the underwriting discounts and commissions. The warrants that were issued in connection with the 3,000,000 over-allotment Units are identical to the public warrants and have no net cash settlement provisions. The underwriters exercised the over-allotment option in full on March 13, 2020. The underwriters did not receive any underwriting discounts or commission on the Units purchased by the Deerfield Funds. The Company paid an underwriting discount of 2.0% of the per Unit offering price, or $3.6 million, at the closing of the Initial Public Offering, with an additional fee (the “Deferred Underwriting Fees”) of 3.5% of the gross offering proceeds, or $6.3 million, payable upon the Company’s completion of an Initial Business Combination. The Deferred Underwriting Fees will become payable to the underwriters from the amounts held in the Trust Account solely in the event the Company completes its initial Business Combination. Risks and uncertainties Management continues to evaluate the impact of the COVID-19 pandemic on its industry and has concluded that, while it is reasonably possible that the virus could have a negative effect on the Company’s financial position, results of its operations and/or search for a target company, the specific impact is not readily determinable as of the date of these financial statements. The financial statements do not include any adjustments that might result from the outcome of this uncertainty.

Commitments and Contingencies
Commitments and Contingencies	Note 15. Commitments and Contingencies The Company evaluates contingencies based upon available evidence. In addition, allowances for losses are provided each year for disputed items which have continuing significance. The Company believes that allowances for losses have been provided to the extent necessary, and that its assessment of contingencies is reasonable. Due to the inherent uncertainties and subjectivity involved in accounting for contingencies, there is at least a reasonable possibility that recorded estimates will change by a material amount in the near term. To the extent that the resolution of contingencies results in amounts which vary from management’s estimates, future operating results will be charged or credited. The principal commitments and contingencies are described below. Leases The Company leases its offices, clinics and certain equipment under non-cancellable operating leases, and certain equipment under capital lease agreements, that expire at various dates through 2028. The Company has 49 rental agreements for property. Additionally, the Company has 4 rental agreements for medical equipment classified as capital leases. Future minimum lease payments under noncancellable operating leases (with initial or remaining lease terms in excess of one year) and future minimum capital lease payments as of September 30, 2021 were: Capital Operating leases leases Year ending December 31: 2021 $ 8,572 $ 874,490 2022 36,736 3,430,762 2023 36,736 3,151,293 2024 30,614 2,673,093 2025 — 2,141,122 Thereafter — 1,674,718 Total minimum lease payments $ 112,658 $ 13,945,478 Less: amount representing interest (6% interest rate) (8,286) Present value of net minimum capital lease payments 104,372 Less current installments of obligations under capital leases (32,344) Obligations under capital leases, excluding current installments $ 72,028 Legal Matters The Company is subject to certain outside claims and litigation arising in the ordinary course of business. In the opinion of management, the outcome of such matters will not have a material effect on the Company’s condensed consolidated financial statements. Loss contingencies entail uncertainty and a possibility of loss to an entity. If the loss is probable and the amount of loss can be reasonably estimated, the loss should be accrued according to Accounting Standards Codification No. 450-20, Disclosure of Certain Loss Contingencies Indemnities The Company’s Articles of Incorporation and bylaws require it, among other things, to indemnify the director or officer against specified expenses and liabilities, such as attorneys’ fees, judgments, fines, and settlements, paid by the individual in connection with any action, suit, or proceeding arising out of the individual’s status or service as its director or officer, other than liabilities arising from willful misconduct or conduct that is knowingly fraudulent or deliberately dishonest, and to advance expenses incurred by the individual in connection with any proceeding against the individual with respect to which the individual may be entitled to indemnification by the Company. The Company also indemnifies its lessor in connection with its facility lease for certain claims arising from the use of the facilities. These indemnities do not provide for any limitation of the maximum potential future payments it could be obligated to make. Historically, the Company has not incurred any payments for these obligations and, therefore, no liabilities have been recorded for these indemnities in the accompanying condensed consolidated balance sheet. The Health Insurance Portability and Accountability Act The Health Insurance Portability and Accountability Act (“HIPAA”) assures health insurance portability, reduces healthcare fraud and abuse, guarantees security and privacy of health information, and enforces standards for health information. Organizations are required to be in compliance with HIPAA provisions. The Health Information Technology for Economic and Clinical Health Act (“HITECH”) imposes notification requirements in the event of certain security breaches relating to protected health information. Organizations are subject to significant fines and penalties if found not to be compliant with the provisions outlined in the regulations.The Company believes it is in compliance with these laws. Regulatory Matters Laws and regulations governing the Medicare program and healthcare generally, are complex and subject to interpretation. The Company believes that it is in compliance with all applicable laws and regulations and is not aware of any pending or threatened investigations involving allegations of potential wrongdoing. While no regulatory inquiries have been made, compliance with such laws and regulations can be subject to future government review and interpretation as well as significant regulatory action including fines, penalties, and exclusion from the Medicare and Medi-Cal programs. Many of the Company’s payor and provider contracts are complex in nature and may be subject to differing interpretations regarding amounts due for the provision of medical services. Such differing interpretations may not come to light until a substantial period of time has passed following contract implementation. Liabilities for claims disputes are recorded when the loss is probable and can be estimated. Any adjustments to reserves are reflected in current operations. The Company does not have any reserves for regulatory matters as of September 30, 2021 and December 31, 2020. Liability Insurance The Company believes that its insurance coverage is appropriate based upon the Company’s claims experience and the nature and risks of the Company’s business. In addition to the known incidents that have resulted in the assertion of claims, the Company cannot be certain that its insurance coverage will be adequate to cover liabilities, arising out of claims asserted against the Company or the Company’s affiliated professional organizations, in the future where the outcomes of such claims are unfavorable. The Company believes that the ultimate resolution of all pending claims, including liabilities in excess of the Company’s insurance coverage, will not have a material adverse effect on the Company’s financial position, results of operations or cash flows; however, there can be no assurance that future claims will not have such a material adverse effect on the Company’s business. Contracted physicians are required to obtain their own insurance coverage.	Note 15. Commitments and Contingencies The Company evaluates contingencies based upon available evidence.

Loss contingencies entail uncertainty and a possibility of loss to an entity. If the loss is probable and the amount of loss can be reasonably estimated, the loss should be accrued according to ASC 450-20. As of the end of December 31, 2020, the Company accrued a loss contingency for a legal matter related to an employee lawsuit, which was settled in 2021 for approximately$350,000. Indemnities The Company’s Articles of Incorporation and bylaws require it, among other things, to indemnify the director or officer against specified expenses and liabilities, such as attorneys’ fees, judgments, fines, and settlements, paid by the individual in connection with any action, suit, or proceeding arising out of the individual’s status or service as its director or officer, other than liabilities arising from willful misconduct or conduct that is knowingly fraudulent or deliberately dishonest, and to advance expenses incurred by the individual in connection with any proceeding against the individual with respect to which the individual may be entitled to indemnification by the Company.

TOI Parent Inc.
Business Combination
Business Combination	Note 16. Business Combination On February 12, 2021 (the “Acquisition Date”), the Company entered into an asset purchase agreement and master services agreement (PCC MSA) with Anil N Raiker, M.D., P.L.C., d/b/a Pinellas Cancer Center (“PCC”) and Anil Raiker, M.D., an individual. Pursuant to the asset purchase agreement, the Company purchased from PCC certain non-clinical assets, properties, and rights. Pursuant to the PCC MSA, TOI Management established an ongoing management services agreement which grants TOI Management the right to control the non-clinical and management operations of PCC. Anil Raiker, M.D. continued to own all of the issued and outstanding equity interests of PCC. Pursuant to the PCC MSA, and as further described in Note 17, TOI Management became PCC’s primary beneficiary and thus consolidated PCC and its subsidiaries. The consolidation of PCC (the “Acquisition”) at the Acquisition Date constituted a business combination in accordance with ASC 805. See Note 2 for a summary of the Company’s policies related to business combinations. The estimated fair value of the net assets acquired at the Acquisition Date amounted to $256,514. The total consideration for the Acquisition was $1,710,000, comprised of a cash payment of $892,500 and deferred consideration of $817,500. The deferred cash consideration is to be paid in two equal installments on the first and second anniversary of the transaction closing date (February 12, 2022 and 2023, respectively). Considering the Company’s incremental borrowing rate, the present value of the deferred cash consideration is not materially different than its stated value. The purchase consideration for the Acquisition has been allocated under the acquisition method of accounting to the estimated fair market value of the net assets acquired including a residual amount of tax deductible goodwill of approximately $1,453,486. The Acquisition was made primarily to expand the Company’s market share to the Florida market. The goodwill of $1,453,486 arising from the purchase is derived largely from the expected growth of the Company, as well as synergies and economies of scale expected from combining operations with the Company. The establishment of the allocation to goodwill requires the extensive use of accounting estimates and management judgement. The fair values assigned to the assets acquired are based on estimates and assumptions from data that is readily available. Consideration: Cash $ 892,500 Deferred consideration arrangement 817,500 Fair value of total consideration transferred 1,710,000 Estimated fair value of assets acquired and liabilities assumed: Cash 65,042 Accounts receivable 248,816 Inventory 62,656 Other receivables 149,398 Goodwill 1,453,486 Total assets acquired 1,979,398 Accounts payable 120,000 Debt, inclusive of PPP 149,398 Total liabilities assumed 269,398 Net assets acquired $ 1,710,000 Subsequent to the Acquisition, the Company filed an amendment to the articles of incorporation of PCC to legally change the name to The Oncology Institute FL, LLC (TOI FL). The change was solely nominal, and the legal form, tax attributes, and books and records of PCC all remained. The revenues, earnings, and pro forma effects of the Acquisition are not and	Note 16. Business Combination Business Combination Information During 2018, the Agajanian Family Trust, American Institute of Research, and Richy Agajanian Holdings, a Professional Corporation, founded TOI Management as a management services organization for provider organizations. On September 19, 2018 (the “Acquisition Date”), TOI Management acquired all the non-clinical assets of the Practice, ICRI, and HHHC in exchange for TOI Management’s equity (the “Non-Clinical Asset Purchase”). Concurrently on the Acquisition Date, TOI Management entered into a management services agreement (the “MSA”) with the Practice and its subsidiaries to provide comprehensive management and administrative services. Pursuant to the MSA, and as further described in Note 17, TOI Management became the Practice’s primary beneficiary and thus consolidated the Practice and its subsidiaries. The consolidation of the Practice (together with the Non-Clinical Asset Purchase, the “Acquisition”) at the Acquisition Date resulted in the fair valuation of the Practice’s net assets. Intangible assets identified included payor contracts, trade names, and clinical contracts, which were recorded at fair value. The remaining difference in net assets at fair value was allocated to goodwill. See Note 2 for a summary of the Company’s policies relating to business combinations. The total consideration transferred was $44,958,702, of which $34,875,000 was in cash and rollover units valued at $10,083,702. Acquisition and integration expenses paid the Company totaled $3,184,660 for the year ended December 31, 2018 and are included in the Successor financial statements in selling, general, and administrative expenses. The fair value of assets acquired and liabilities assumed as part of the Acquisition is summarized as follows: Fair value of assets acquired and liabilities assumed: Cash $ 505,317 Accounts receivable 11,097,858 Inventories 2,707,640 Prepaid expenses and other 144,447 Property and equipment, net 388,511 Goodwill 14,076,674 Intangible assets, net 25,234,000 Total assets acquired $ 54,154,447 Accounts payable $ 136,989 Accrued expenses and other current liabilities 7,658,103 Deferred tax liability 1,400,653 Total liabilities assumed $ 9,195,745 Net assets acquired $ 44,958,702 In determining the fair value of the intangible assets, the Company considered, among other factors, the best use of the acquired assets, analyses of historical financial performance of the services, and estimates of future performance of the products and intellectual properties acquired. The Company has recorded the purchase price of the identified intangible assets and is amortizing such values over their estimated useful life of 10 years. The goodwill of $14,076,674 arising from the purchase is derived largely from the expected growth of the Company, as well as synergies and economies of scale expected from combining the Practice and ICRI and centrally managing the two with TOI Management. The establishment of the allocation to goodwill and identifiable intangible assets requires the extensive use of accounting estimates and management judgement. The fair values assigned to the assets acquired are based on estimates and assumptions from data that is readily available. All of the acquired goodwill is deductible for tax purposes. Unaudited Supplemental Pro Forma Information The pro forma results presented below include the effects of the Acquisition as if it had occurred on January 1, 2018. The pro forma results for the year ended December 31, 2018 include the additional amortization resulting from the adjustments to the value of intangible assets resulting from purchase accounting. The pro forma results do not include any anticipated synergies or other expected benefits of the acquisitions. The pro forma information does not purport to be indicative of what our results of operations would have been if the Acquisition had in fact occurred at the beginning of the period presented and is not intended to be a projection of our future results of operations. Transaction expenses are included within the pro forma results. The unaudited pro forma combined revenue and net income for the twelve months ended December 31, 2018 are $113,160,114 and $2,136,657 respectively.

In conjunction with the MSA, TOI Management entered into a stock transfer restriction agreement which granted the TOI Management, a non-equity holder in the Practice, the right to direct the most significant activities of the Practice. Therefore, the Practice is a variable interest entity and TOI Management is the primary beneficiary that consolidates the Practice and its subsidiaries.

Summary of Significant Accounting Policies (Policies)	9 Months Ended	12 Months Ended
Summary of Significant Accounting Policies (Policies)	Sep. 30, 2021	Dec. 31, 2020
Basis of Presentation		Basis of presentation The Company’s financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”) for financial information and pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). The Company has no subsidiaries. As described in Note 2—Restatement of Previously Issued Financial Statements, the Company’s financial statements for the period as of December 31, 2020, and the year ended December 31, 2020, as of September 30, 2020 and for the three and nine months ended September 30, 2020, as of June 30, 2020 and for the three and six months ended June 30, 2020, and as of March 31, 2020 and for the three months ended March 31, 2020 (collectively, the “2020 Affected Periods”), are restated in this Annual Report on Form 10-K/A (Amendment No. 2) (this “Annual Report”) to correct the misapplication of accounting guidance related to the redeemable Class A common stock and earnings per share in the Company’s previously issued audited and unaudited condensed financial statements for such periods. The restated financial statements are indicated as “Restated” in the audited and unaudited condensed financial statements and accompanying notes, as applicable. See Note 2—Restatement of Previously Issued Financial Statements for further discussion.
Principles of Consolidation	Basis of Presentation and Principles of Consolidation The accompanying unaudited condensed consolidated financial statements are presented in U.S. dollars in conformity with accounting principles generally accepted in the United States of America (“GAAP”) for financial information and pursuant to the rules and regulations of the SEC. Accordingly, they do not include all of the information and footnotes required by GAAP. In the opinion of management, the unaudited condensed consolidated financial statements reflect all adjustments, which include only normal recurring adjustments necessary for the fair statement of the balances and results for the period presented. Operating results for the period for the three and nine months ended September 30, 2021, are not necessarily indicative of the results that may be expected for the period ending December 31, 2021. The unaudited condensed consolidated financial statements of the Company include its wholly owned subsidiaries in connection with the proposed business combination (as described below). All inter-company accounts and transactions are eliminated in consolidation. The accompanying unaudited condensed consolidated financial statements should be read in conjunction with the audited financial statements and notes thereto included in the Form 10-K/A filed by the Company with the SEC on May 24, 2021.
Use of Estimates	Use of Estimates The preparation of unaudited condensed consolidated financial statements in conformity with GAAP requires the Company’s 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 unaudited condensed consolidated financial statements and the reported amounts of revenue and expenses during the reporting period. Making estimates requires management to exercise significant judgment. It is at least reasonably possible that the estimate of the effect of a condition, situation or set of circumstances that existed at the date of the unaudited condensed consolidated financial statements, which management considered in formulating its estimate, could change in the near term due to one or more future confirming events. One of the more significant accounting estimates included in these unaudited condensed financial statements is the determination of the fair value of the derivative warrant liabilities. Accordingly, the actual results could differ significantly from those estimates.

Net Loss Per Share	Net Income (Loss) Per Share of Common Stock The Company complies with accounting and disclosure requirements of FASB ASC Topic 260, “Earnings Per Share.” The Company has two classes of shares, which are referred to as Class A common stock and Class B common stock. Income and losses are shared pro rata between the two classes of shares. Net income (loss) per share of common stock is calculated by dividing the net income (loss) by the weighted average shares of common stock outstanding for the respective period. The calculation of diluted net income (loss) per share of common stock does not consider the effect of the warrants issued in connection with the Initial Public Offering and the Private Placement to purchase an aggregate of 9,483,334 shares of common stock in the calculation of diluted income (loss) per share, because their exercise is contingent upon future events and their inclusion would be anti-dilutive under the treasury stock method. As a result, diluted net income (loss) per share is the same as basic net income (loss) per share of common stock for the three and nine months ended September 30, 2021 and 2020. Accretion associated with the redeemable Class A common stock is excluded from earnings per share as the redemption value approximates fair value. The following table presents a reconciliation of the numerator and denominator used to compute basic and diluted net income (loss) per share for each class of common stock: For the Three Months Ended September 30, For the Nine Months Ended September 30 2021 2020 2021 2020 Class A Class B Class A Class B Class A Class B Class A Class B Basic and diluted net income (loss) per share of common stock: Numerator: Allocation of net income - basic $ (345,627) $ (86,407) $ (1,933,328) $ (483,332) $ (693,980) $ (173,495) $ (4,378,377) $ (1,433,857) Allocation of net income - diluted $ (345,627) $ (86,407) $ (1,933,328) $ (483,332) $ (693,980) $ (173,495) $ (4,340,374) $ (1,471,860) Denominator: Basic weighted average common shares outstanding 23,000,000 5,750,000 23,000,000 5,750,000 23,000,000 5,750,000 16,956,204 5,552,920 Diluted weighted average common shares outstanding 23,000,000 5,750,000 23,000,000 5,750,000 23,000,000 5,750,000 16,956,204 5,750,000 Basic net income (loss) per share of common stock $ (0.02) $ (0.02) $ (0.08) $ (0.08) $ (0.03) $ (0.03) $ (0.26) $ (0.26) Diluted net income (loss) per share of common stock $ (0.02) $ (0.02) $ (0.08) $ (0.08) $ (0.03) $ (0.03) $ (0.26) $ (0.26)	Net Income (Loss) Per Share of Common Stock The Company complies with accounting and disclosure requirements of FASB ASC Topic 260, “Earnings Per Share.” The Company has two classes of shares, which are referred to as Class A common stock and Class B common stock.

Cash	Cash and Cash Equivalents The Company considers all short-term investments with an original maturity of three months or less when purchased to be cash equivalents. The Company had no cash equivalents as of September 30, 2021 and December 31, 2020.

The Company had no cash equivalents as of December 31, 2020, and 2019.
Income Taxes	Income Taxes The Company complies with the accounting and reporting requirements of Financial Accounting Standards Board Accounting Standard Codification, or ASC, 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. There were no unrecognized tax benefits as of September 30, 2021, and as of December 31, 2020. ASC 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 as income tax expense. No amounts were accrued for the payment of interest and penalties as of September 30, 2021, and December 31, 2020. The Company is currently not aware of any issues under review that could result in significant payments, accruals or material deviation from its position. The Company is subject to income tax examinations by major taxing authorities since inception.

Fair Value Measurements	Fair Value Measurements Fair value is defined as the price that would be received for sale of an asset or paid for transfer of a liability, in an orderly transaction between market participants at the measurement date. GAAP establishes a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). These tiers consist of: ● Level 1: Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities; ● Level 2: Quoted prices in markets that are not active or financial instruments for which significant inputs to models are observable (including but not limited to quoted prices for similar securities, interest rates, foreign exchange rates, volatility and credit risk), either directly or indirectly; ● Level 3: Prices or valuations that require significant unobservable inputs (including the Management’s assumptions in determining fair value measurement). In some circumstances, the inputs used to measure fair value might be categorized within different levels of the fair value hierarchy. In those instances, the fair value measurement is categorized in its entirety in the fair value hierarchy based on the lowest level input that is significant to the fair value measurement. As of September 30, 2021, the carrying values of cash, accounts payable, accrued expenses, prepaid expenses and franchise tax payable approximate their fair values due to the short-term nature of the instruments. The Company’s investments held in Trust Account are comprised of investments in U.S. Treasury securities with an original maturity of 185 days or less or investments in money market funds that comprise only U.S. Treasury securities and are recognized at fair value. The fair value of investments held in Trust Account is determined using quoted prices in active markets.
Recently Adopted Accounting Standards	Recent Accounting Pronouncements In August 2020, the Financial Accounting Standards Board issued Accounting Standard Update (“ASU”) No. 2020-06, Debt—Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging—Contracts in Entity’s Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity The Company’s management does not believe that any other recently issued, but not yet effective, accounting standards updates, if currently adopted, would have a material effect on the accompanying unaudited condensed consolidated financial statements.	Recent Accounting Pronouncements 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.
TOI Parent Inc.
Basis of Presentation	Unaudited Interim Financial Information The accompanying interim condensed consolidated financial statements are unaudited and have been prepared in accordance with Article 10 of Regulation S-X issued by the Securities and Exchange Commission (“SEC”). Accordingly, they do not include all of the information and note disclosures required by U.S. generally accepted accounting principles (“GAAP”) for complete financial statements. However, the Company believes that the disclosures are adequate to make that information not misleading. In the opinion of management, all adjustments (of normal and recurring nature) considered necessary for fair presentation have been reflected in these interim statements. As such, the information included in the accompanying unaudited interim condensed consolidated financial statements should be read in conjunction with the Company’s audited consolidated financial statements and notes as of, and for the year ended December 31, 2020, issued on June 27, 2021.	Basis of Presentation The accompanying consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”). During fiscal year 2018, the Company presents financial information for the Practice for the period from January 1, 2018 through September 19, 2018 (“Predecessor Period”) and for the Company for the period from September 20, 2018 through December 31, 2018 (“Successor Period”).
Principles of Consolidation	Principles of Consolidation The accompanying unaudited condensed consolidated financial statements include the accounts of TOI Parent, its subsidiaries, all of which are controlled by the Parent through majority voting control or are variable interest entities (“VIEs”) for which TOI Parent (through TOI Management) is the primary beneficiary. The Company consolidates entities in which it has a controlling financial interest based on either the variable interest entity or voting interest model. All significant intercompany balances and transactions have been eliminated in consolidation.

Variable Interest Entities	Variable Interest Entities The Company consolidates entities for which it has a variable interest and is determined to be the primary beneficiary. Noncontrolling interests in less-than-wholly-owned consolidated subsidiaries of the Company are presented as a component of total equity, to the extent they are material, to distinguish between the interests of the Company and the interests of the noncontrolling owners. Revenues, expenses, and income from these subsidiaries are included in the consolidated amounts as presented on the consolidated statements of operations. The Company holds variable interests in clinical practices, for which it cannot legally own, as a result of entering into master services agreements (“MSAs”) with such practices. TOI Parent holds a variable interest in TOI CA, which is a VIE. The Company is the primary beneficiary of TOI CA and thus, consolidates TOI CA in its financial statements. Further, as a result of the February 2021 acquisition, discussed in Note 16, the Company holds an additional variable interest in TOI FL, which was determined to be a VIE. The Company determined that it is a primary beneficiary of TOI FL and thus, consolidates the entity in its financial statements. As discussed in Note 17, the shareholders of the Company’s consolidating VIEs own a minority of the issued and outstanding common shares of the Company.

Revenues, expenses, and net income from these subsidiaries are included in the consolidated amounts as presented on the consolidated statements of operations. The Company holds a variable interest in the Practice as a result of entering into a master services agreement (“MSA”) in conjunction with the acquisition in September of 2018. As a result of the acquisition, HHHC is now a wholly-owned subsidiary of TOI Parent, the Practice is now a VIE of TOI Parent, as discussed in Note 17, and the Practice shareholders own a minority of the issued and outstanding common shares of the Company.

Net Loss Per Share	Net Income (Loss) Per Share The Company has not issued substantive common shares since inception. The Company’s Series A Preferred Shares are considered in-substance common stock since the net income (loss) of the Company is attributable to the Series A Preferred shareholders, and therefore, they are included in the denominator to calculate net income (loss) per share. Basic net income (loss) per share is calculated by dividing net income (loss) attributable to TOI Parent, Inc. by the weighted average Series A Preferred Shares, on an as-converted basis (see Note 19), and common shares issued and outstanding during the period. Diluted net income (loss) per share is calculated by dividing net income (loss) by the weighted average number of Series A Preferred Shares and common shares used in the basic income (loss) per share calculation plus the number of potential common shares that would be issued assuming exercise of all potentially dilutive instruments. Potentially dilutive instruments are excluded from the calculation of diluted income (loss) per share if the effect of including such instruments is anti-dilutive. Given the Company incurred a net loss in each period presented, the stock options outstanding during each period are anti-dilutive. As such, diluted net loss per share is the same as basic net loss per share for each period presented.	Net Loss Per Share The Company has not issued substantive common shares since inception.

Revenue Recognition		Revenue Recognition The Company follows the accounting requirements of Accounting Standard Codification Topic No. 606, Revenue from Contracts with Customers 1. Identification of the contract, or contracts, with a customer. 2. Identification of the performance obligations in the contract. 3. Determination of the transaction price. 4. Allocation of the transaction price to the performance obligations in the contract. 5. Recognition of revenue when, or as, we satisfy a performance obligation. The Company receives payments from the following sources for services rendered: (i) commercial insurers; (ii) the federal government under the Medicare program administered by the Centers for Medicare and Medicaid Services (“CMS”); (iii) state governments under the Medicaid and other programs; (iv) other third-party payors (e.g., hospitals and independent practice associations [“IPAs”]); and (v) individual patients and clients. Revenue primarily consists of capitation revenue, fee-for-service (“FFS”) revenue, dispensary revenue, and clinical trials revenue. Revenue is recognized in the period in which services are rendered or the period in which the Company is obligated to provide services. The form of billing and related risk of collection for such services may vary by type of revenue and the payor. The following paragraphs provide a summary of the principal forms of the Company’s billing arrangements and how revenue is recognized for each. Capitation Capitation revenues of the Company consist primarily of fees for medical services provided to patients by the Company under a capitated arrangement with various managed care organizations. Capitation revenue is paid monthly to the Company based on the number of enrollees assigned to the Company by the contracted managed care organization (per member, per month; or “PMPM”). Capitation contracts generally have a legal term of one year or longer. Capitation contracts have a single performance obligation that is a stand ready obligation to perform healthcare services to the population of enrolled members and constitutes a series for the provision of managed healthcare services for the term of the contract, which is deemed to be one month since the mix of patient-customers can and do change month over month. The transaction price for capitation contracts is variable as it primarily includes PMPM fees associated with unspecified membership that fluctuates throughout the contract. The Company generally estimates the transaction price using the most likely methodology and amounts are only included in the transaction price to the extent that it is probable that a significant reversal of cumulative revenue will not occur once any uncertainty is resolved. Certain contracts include terms for a capitation deduction where the cost of out-of-network referrals of members by the Company are deducted from the future payment. The deductions vary depending on the payor and are often not known until a future period. As such, the Company adjusts the transaction price for capitation deductions based on historic experience such that the amount of capitation revenue is constrained to the extent that it is not probable a significant reversal of revenue will occur in the future. Revenue is recognized in the month services are rendered on the basis of the transaction price established at that time. If subsequent information resolves uncertainties related to the transaction price, adjustments will be recognized in the period they are resolved. When payment has been received but services have not yet been rendered, the payment is recognized as a contract liability. Fee-for-Service Revenue FFS revenue represents revenue earned under contracts in which the Company bills and collects for medical services rendered by the Company’s employed physicians. The terms for FFS contracts are short in duration and only last for the period over which services are rendered (typically, one day). FFS revenue consists of fees for medical services provided to patients. These medical services are distinct since the patient can benefit from the medical services on their own. Each service constitutes a single performance obligation for which the patient accepts and receives the benefit of the medical services as they are performed. Under the FFS arrangements, the Company bills third-party payors and patients for patient care services provided and receives payment. Payments for services provided are generally less than billed charges. The Company records revenue net of an allowance for contractual adjustments, which represents the net revenue expected to collected from third-party payors (including managed care, commercial, and governmental payors such as Medicare and Medicaid), and patients. These expected collections are based on fees and negotiated payment rates in the case of third-party payors, the specific benefits provided for under each patient’s healthcare plans, mandated payment rates in the case of Medicare and Medicaid programs, and historical cash collections (net of recoveries). The transaction price from FFS arrangements is variable in nature because fees are based on patient encounters, credits due to patients, and reimbursement of provider costs, all of which can vary from period to period. The Company estimates the transaction price using the most likely methodology and amounts are only included in the net transaction price to the extent that it is probable that a significant reversal of cumulative revenue will not occur once any uncertainty is resolved. As a practical expedient, the Company adopted a portfolio approach to determine the transaction price for the medical services provided under FFS arrangements. Under this approach, the Company bifurcated the types of services provided and grouped health plans with similar fees and negotiated payment rates. At these levels, portfolios share the characteristics conducive to ensuring that the results do not materially differ from the standard applied to individual patient contracts related to each medical service provided. The recognition of net revenue (gross charges less contractual allowances) from such services is dependent on such factors as proper completion of medical charts following a patient visit, the forwarding of such charts to the Company’s billing center for medical coding and entering into the Company’s billing system, and the verification of each patient’s submission or representation at the time services are rendered as to the payor(s) responsible for payment of such services. Revenue is recorded on the date the services are rendered based on the information known at the time of entering of such information into the Company’s billing systems as well as an estimate of the revenue associated with medical services. When the performance obligation is not satisfied, the billing is recognized as a contract liability. Dispensary The Company sells oral prescription drugs directly through its dispensaries. Each prescription filled and delivered to the customer is a distinct performance obligation. The transaction price for the prescriptions is based on fee schedules set by various pharmacy benefit managers (“PBMs”) and other third party payors. The fee schedule is often subject to direct and indirect remuneration (“DIR”) fees, which are based primarily on pre-established metrics. DIR fees may be assessed in periods after payments are received against future payments. The Company estimates DIR fees to arrive at the transaction price for prescriptions. The Company recognizes revenue based on the transaction at the time the customer takes possession of the oral drug. Clinical Trials Revenue The Company enters into contracts to perform clinical research trials. The terms for clinical trial contracts last many months as the clinical research is performed. Each contract represents a single, integrated set of research activities and thus is a single performance obligation. The performance obligation is satisfied over time as the output is captured in data and documentation that is available for the customer to consume over the course of arrangement and furthers progress of the clinical trial. Under the clinical trial contracts, the Company receives a fixed payment for administrative, set-up, and close-down fees; a fixed amount for each patient site visit; and certain expense reimbursements. Under ASC 606, the Company has elected to recognize revenue for these arrangements using the ‘as-invoiced’ practical expedient. The Company invoices the customer periodically based on the progress of the trial such that each invoice captures the revenue earned to date based on the state of the trial as established between the Company and the customer.
Direct Costs of Sales		Direct Costs of Sales Direct cost of sales primarily consists of wages paid to clinical personnel and other health professionals, oral and IV drug costs, and other medical supplies used to provide patient care. The Company’s costs for clinical personnel wages are expensed as incurred and the Company’s costs for inventory and medical supplies are expensed when used, generally by applying the specific identification method.
Cash		Cash Cash consists of deposits with banking institutions. The carrying value of the Company’s cash approximates fair value due to the short-term maturity of these instruments (less than three months).
Accounts Receivable		Accounts Receivable The Company accounts for accounts receivable under Accounting Standard Codification Topic No. 310, Receivables For third-party payors including Medicare, Medicaid, managed care providers, and commercial payors, the collectable amount is based on the estimated contractual reimbursement percentage, which is based on current contract prices or historical paid claims data by payor. For self-pay accounts receivable, which includes patients who are uninsured and the patient responsibility portion for patients with insurance, the collectable amount is determined using estimates of historical collection experience without regard to aging category.These estimates are adjusted for estimated conversions of patient responsibility portions, expected recoveries, and any anticipated changes in trends. Accounts receivable can be impacted by the effectiveness of the Company’s collection efforts.Additionally, significant changes in payor mix, business office operations, economic conditions, or trends in federal and state governmental healthcare coverage could affect the collectable amount of accounts receivable. The Company maintains reserves for potential credit losses on accounts receivable. Management reviews the composition of accounts receivable and analyzes historical bad debts, customer concentrations,customer credit worthiness, current economic trends, and changes in customer payment patterns to evaluate the adequacy of these reserves. The Company also regularly analyzes the ultimate collectability of accounts receivable after certain stages of the collection cycle using a look-back analysis to determine the amount of receivables subsequently collected, and adjustments are recorded when necessary. The Company continuously monitors its collections of receivables and its policy is to write off receivables when they are determined to be uncollectible. As of December 31, 2020 and 2019, the Company does not have an allowance for doubtful accounts.
Inventories		Inventories The Company accounts for inventory under Accounting Standard Codification Topic No. 330, Inventory The Company receives purchase discounts on products purchased. Contractual arrangements with vendors, including manufacturers and wholesalers, normally provide for the Company to receive purchase discounts from established list prices in one, or a combination, of the following forms: (i) a direct discount at the time of purchase or (ii) a discount for the prompt payment of invoices. Additionally, in other circumstances, the Company may receive rebates when products are purchased indirectly from a manufacturer (e.g., through a wholesaler). These rebates are recognized when intravenous chemotherapy drugs and oral prescription drugs are dispensed and are generally calculated by manufacturers within 30 days after the end of each completed quarter. The Company also receives additional rebate under its wholesaler contracts if it exceeds contractually defined annual purchase volumes. Purchase rebates are recorded as reductions to cost of services.
Property and Equipment, net		Property and Equipment, net The Company accounts for property and equipment under Accounting Standard Codification Topic No. 360, Property, Plant, and Equipment When events or changes in circumstances indicate that the carrying amount of long-lived assets, including property and equipment, or other long-lived assets, may not be recoverable, an evaluation of the recoverability of currently recorded costs is performed. When an evaluation is performed, the estimated value of undiscounted future net cash flows associated with the asset groups is compared to the asset groups’ carrying value to determine if a write-down to fair value is required. If such assets are considered to be impaired, the impairment to be recognized is measured as the amount by which the carrying amount of the asset group exceeds the fair value of the assets. There were no impairment adjustments recorded for long- lived assets during the years ended December 31, 2020, 2019, the Successor Predecessor
Accounts payable, Accrued Expenses, and Other Current Liabilities		Accounts Payable, Accrued Expenses, and Other Current Liabilities Accounts payable primarily consists of unpaid invoices related to routine operating expenses. Accrued expenses and other current liabilities primarily consist of accruals made for payroll expenses, deferred capitation, and FFS revenue.
Leases		Leases Lease agreements are evaluated to determine whether they are capital or operating leases in accordance with Accounting Standards Codification, Topic No. 840, Leases
Goodwill and Intangible Assets		Goodwill and Intangible Assets The Company accounts for goodwill and intangible assets under Accounting Standards Codification Topic No. 350, Goodwill and Other Goodwill is not amortized but is required to be evaluated for impairment at the same time every year. The Company performs its annual testing of impairment for goodwill in the fourth quarter of each year. When impairment indicators are identified, the Company compares the reporting unit’s fair value to its carrying amount, including goodwill. An impairment loss is recognized as the difference, if any, between the reporting unit’s carrying amount and its fair value to the extent the difference does not exceed the total amount of goodwill allocated to the reporting unit. The Company performed a qualitative analysis and determined that no indicators of impairment existed at December 31, 2020 and 2019 and therefore, there was no goodwill impairment charge during the years ended December 31, 2020, 2019, and the Successor Period, as a result of the Company’s annual impairment evaluation. Under ASC 350, finite-lived intangible assets are stated at acquisition-date fair value. Intangible assets are amortized using the straight-line method. Finite-lived intangible assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. When circumstances indicate that recoverability may be impaired, the Company assesses its ability to recover the carrying value of the asset group from the expected future pre-tax cash flows (undiscounted and without interest charges) of the related operations. If these cash flows are less than the carrying value of such asset, an impairment loss is recognized for the difference between estimated fair value and carrying value. Fair value is determined based on appropriate valuation techniques. The Company performed a qualitative analysis and determined that there were no indicators of impairment of its finite-lived intangible assets during the years ended December 31, 2020, 2019, and the Successor Period.
Debt		Debt The Company accounts for debt net of debt issuance costs. Debt issuance costs are capitalized, netted against the related debt for presentation purposes, and amortized to interest expense over the terms of the related debt using the effective interest method.
Income Taxes		Income Taxes The Company accounts for income taxes under the asset and liability method under Accounting Standards Codification Topic No. 740, Income Taxes
Share-Based Compensation Plan		Share-Based Compensation Plan The Company accounts for share-based compensation under Accounting Standards Codification Topic No. 718, Stock Based Compensation Excess tax benefits of awards related to stock option exercises are recognized as an income tax benefit in the statement of operations and reflected in operating activities in the statement of cash flows.
Commitments and Contingencies		Commitments and Contingencies The Company accounts for contingent liabilities under Accounting Standards Codification Subtopic No. 450-20, Contingencies
Fair Value Measurements		Fair Value Measurements The Company accounts for fair value measurements under Accounting Standards Codification Topic No. 820, Fair Value Measurements ● Level 1 inputs: Unadjusted quoted prices in active markets for identical assets or liabilities accessible to the reporting entity at the measurement date. ● Level 2 inputs: Other than quoted prices included in Level 1 inputs that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the asset or liability. ● Level 3 inputs: Unobservable inputs for the asset or liability used to measure fair value to the extent that observable inputs are not available, thereby allowing for situations in which there is little, if any, market activity for the asset or liability at measurement date.

The new standard requires lessees to record a right-of-use (“ROU”) asset and a corresponding lease liability on the balance sheet (with the exception of short-term leases), whereas under current accounting standards the Company’s lease portfolio consists primarily of operating leases and is not recognized on its consolidated balance sheets. The Company will adopt ASC 842 effective January 1, 2022, using the alternative modified transition method and will record a cumulative-effect adjustment to the opening balance of retained earnings as of that date. Prior periods will not be restated. The Company believes the largest impact will be on the consolidated balance sheets for the accounting of facilities-related leases, which represents a majority of its operating leases it has entered into as a lessee. These leases will be recognized under the new standard as ROU assets and operating lease liabilities. The Company will also provide expanded disclosures for its leasing arrangements. The results of operations are not expected to significantly change after adoption of the new standard.

Description of the Business
Organization, Business Operations	1. Organization, Business Operations. Incorporation The Oncology Institute, Inc., formerly DFP Healthcare Acquisitions Corp, (the “Company,” or “DFP”) was incorporated as a Delaware corporation on November 1, 2019. Sponsor The Company’s sponsor is DFP Sponsor LLC, a Delaware limited liability company (the “Sponsor”). Business Purpose The Company was formed for the purpose of effecting a merger, capital stock exchange, asset acquisition, stock purchase, reorganization or other similar business combination with one or more operating businesses (“Business Combination”). The Company has neither engaged in any operations nor generated revenue to date. As of September 30, 2021, the Company had not commenced any operations. All activity for the period from November 1, 2019 (inception) through September 30, 2021, relates to the Company’s formation and the initial public offering (the “Initial Public Offering”) described below, and since the Initial Public Offering, identifying a target company for a Business Combination. The Company will not generate any operating revenues until after the completion of its initial Business Combination, at the earliest. The Company generates non-operating income in the form of interest income on cash and cash equivalents from the proceeds derived from the Initial Public Offering. The Company’s management has broad discretion with respect to the specific application of the net proceeds of its Initial Public Offering, although substantially all of the net proceeds of the Initial Public Offering are intended to be generally applied toward completing a Business Combination. Furthermore, there is no assurance that the Company will be able to successfully complete a Business Combination. Financing The registration statement for the Company’s Initial Public Offering was declared effective by the Securities and Exchange Commission (the “SEC”) on March 10, 2020. On March 13, 2020, the Company consummated its Initial Public Offering of 23,000,000 units (the “Units” and, with respect to the Class A common stock included in the Units being offered, the “Public Shares”), including 3,000,000 additional Units to cover over-allotments (the “Over-Allotment Units”), at $10.00 per Unit, generating gross proceeds of $230.0 million, and incurring offering costs of approximately $10.4 million, inclusive of approximately $6.3 million in deferred underwriting commissions (Note 3). Simultaneously with the closing of the Initial Public Offering, the Company consummated the private placement (“Private Placement”) of 3,733,334 warrants (each, a “Private Placement Warrant” and collectively, the “Private Placement Warrants”) at a price of $1.50 per Private Placement Warrant in a private placement to the Sponsor, generating proceeds of $5.6 million (Note 4). Trust Account Upon the closing of the Initial Public Offering and the Private Placement, $230.0 million ($10.00 per Unit) of the net proceeds of the Initial Public Offering and certain of the proceeds of the Private Placement was placed in a trust account (the “Trust Account”) and invested in permitted United States “government securities” within the meaning of Section 2(a)(16) of the Investment Company Act of 1940, as amended, which the Company refers to as the Investment Company Act, having a maturity of 185 days or less or in money market funds meeting certain conditions under Rule 2a-7 promulgated under the Investment Company Act that invest only in direct U.S. government treasury obligations. The Company’s second amended and restated certificate of incorporation provides that, other than the withdrawal of interest earned on the funds that may be released to the Company to pay taxes, none of the funds held in Trust Account will be released until the earlier of: (i) the completion of the Business Combination; (ii) the redemption of the Public Shares to its holders (the “Public Stockholders”) properly tendered in connection with a stockholder vote to amend the Company’s second amended and restated certificate of incorporation to modify the substance or timing of the Company’s obligation to redeem 100% of the Public Shares or with respect to any other material provision relating to stockholders’ rights or pre-initial Business Combination activity, or (iii) the redemption of 100% of the Public Shares if the Company does not complete a Business Combination within 24 months from the closing of the Initial Public Offering. The Company, after signing a definitive agreement for a Business Combination, will either (i) seek stockholder approval of the Business Combination at a meeting called for such purpose in connection with which stockholders may seek to redeem their shares, regardless of whether they vote for or against the Business Combination, for cash equal to their pro rata share of the aggregate amount then on deposit in the Trust Account calculated as of two two If the Company holds a stockholder vote in connection with a Business Combination, a Public Stockholder will have the right to redeem its shares for an amount in cash equal to their pro rata share of the aggregate amount then on deposit in the Trust Account calculated as of two business days prior to the consummation of the initial Business Combination, including interest earned on the funds held in the Trust Account and not previously released to the Company to fund its working capital requirements (subject to an annual limit of $500,000) and/or to pay its taxes. As a result, such common stock is recorded at redemption amount and classified as temporary equity upon the completion of the Initial Public Offering, in accordance with ASC 480, “Distinguishing Liabilities from Equity.” The amount in the Trust Account is initially anticipated to be $10.00 per public share ($230.0 million held in the Trust Account divided by 23,000,000 public shares). The Company will have 24 months from the closing of the Initial Public Offering, or until March 13, 2022, to complete its initial Business Combination (the “ Combination Period”). If the Company does not complete a Business Combination within this period of time, it will (i) cease all operations except for the purposes of winding up; (ii) as promptly as reasonably possible, but not more than ten Going Concern As of September 30, 2021, the Company had approximately $0.2 million in its operating bank account and a working capital deficit of approximately $3.3 million. The Company’s liquidity needs to date have been satisfied through a $25,000 contribution from the Sponsor in exchange for the issuance of the Founder Shares to the Sponsor, the Note (defined below) of $200,000 from the Sponsor, and the proceeds from the consummation of the Private Placement not held in the Trust Account. On March 13, 2020, the Company repaid the Note in full to the Sponsor. In addition, in order to finance transaction costs in connection with a Business Combination, the Sponsor or an affiliate of the Sponsor, or certain of the Company’s officers and directors may, but are not obligated to, provide the Company with Working Capital Loans (see Note 4). As of September 30, 2021, and December 31, 2020, there were no Working Capital Loans outstanding. In connection with the Company’s assessment of going concern considerations in accordance with ASC Topic 205-40, “Presentation of Financial Statements - Going Concern,” management has determined that the liquidity condition and date for mandatory liquidation and subsequent dissolution raise substantial doubt about the Company’s ability to continue as a going concern. No adjustments have been made to the carrying amounts of assets or liabilities should the Company be required to liquidate after March 13, 2022.	Note 1 — Organization, Business Operations and Basis of Presentation Incorporation DFP Healthcare Acquisitions Corp., predecessor to The Oncology Institute, Inc. (the “Company”) was incorporated as a Delaware corporation on November 1, 2019. Sponsor The Company’s sponsor is DFP Sponsor LLC, a Delaware limited liability company (the “Sponsor”). Business Purpose The Company was formed for the purpose of effecting a merger, capital stock exchange, asset acquisition, stock purchase, reorganization or other similar business combination with one or more operating businesses that it has not yet selected (“Business Combination”). The Company has neither engaged in any operations nor generated revenue to date. As of December 31, 2020, the Company had not commenced any operations.

Trust Account Upon the closing of the Initial Public Offering and the Private Placement, $230.0 million ($10.00 per Unit) of the net proceeds of the Initial Public Offering and certain of the proceeds of the Private Placement was placed in a trust account (the “Trust Account”) and invested in permitted United States “government securities” within the meaning of Section 2(a)(16) of the Investment Company Act of 1940, as amended, which the Company refers to as the Investment Company Act, having a maturity of 185 days or less or in money market funds meeting certain conditions under Rule 2a-7 promulgated under the Investment Company Act that invest only in direct U.S. government treasury obligations.

Emerging Growth Company The Company is an “emerging growth company,” as defined in Section 2(a) of the Securities Act of 1933, as amended (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 stockholder approval of any golden parachute payments not previously approved. Further, section 102(b)(1) of the JOBS Act exempts emerging growth companies from being required to comply with new or revised financial accounting standards until private companies (that is, those that have not had a Securities Act registration statement declared effective or do not have a class of securities registered under the Securities Exchange Act of 1934, as amended) 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 an election to opt out is irrevocable. We have 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, we, 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 accountant standards used.

Summary of Significant Accounting Policies
Basis of Presentation and Significant Accounting Policies	2. Basis of Presentation and Significant Accounting Policies. Basis of Presentation and Principles of Consolidation The accompanying unaudited condensed consolidated financial statements are presented in U.S. dollars in conformity with accounting principles generally accepted in the United States of America (“GAAP”) for financial information and pursuant to the rules and regulations of the SEC. Accordingly, they do not include all of the information and footnotes required by GAAP. In the opinion of management, the unaudited condensed consolidated financial statements reflect all adjustments, which include only normal recurring adjustments necessary for the fair statement of the balances and results for the period presented. Operating results for the period for the three and nine months ended September 30, 2021, are not necessarily indicative of the results that may be expected for the period ending December 31, 2021. The unaudited condensed consolidated financial statements of the Company include its wholly owned subsidiaries in connection with the proposed business combination (as described below). All inter-company accounts and transactions are eliminated in consolidation. The accompanying unaudited condensed consolidated financial statements should be read in conjunction with the audited financial statements and notes thereto included in the Form 10-K/A filed by the Company with the SEC on May 24, 2021. Restatement of Previously Reported Financial Statements In preparation of the Company’s unaudited condensed financial statements for the quarterly period ended September 30, 2021, the Company concluded it should restate its previously issued financial statements to classify all Class A common stock subject to possible redemption in temporary equity. In accordance with technical accounting guidance on redeemable equity instruments in ASC 480-10-S99, redemption provisions not solely within the control of the Company, require Class A common stock subject to redemption to be classified outside of permanent equity. The Company had previously classified a portion of its Class A common stock in permanent equity. Although the Company did not specify a maximum redemption threshold, its charter currently provides that the Company will not redeem its Public Shares in an amount that would cause its net tangible assets to be less than $5,000,001. Previously, the Company did not consider redeemable shares classified as temporary equity as part of net tangible assets. Effective with these condensed financial statements, the Company revised this interpretation to include temporary equity in net tangible assets. In connection with the change in presentation for the Class A common stock subject to possible redemption, the Company restated its earnings per share calculation to allocate income and losses shared pro rata between the two classes of shares. This presentation contemplates a Business Combination as the most likely outcome, in which case, both classes of shares participate pro rata in the income and losses of the Company. In accordance with SEC Staff Accounting Bulletin No. 99, “Materiality,” and SEC Staff Accounting Bulletin No. 108, “Considering the Effects of Prior Year Misstatements when Quantifying Misstatements in Current Year Financial Statements,” the Company evaluated the corrections and has determined that the related impact was material to the previously filed financial statements that contained the error, reported in the Company’s Quarterly Reports on Form 10-Q for the quarterly periods ended March 31, 2021 and June 30, 2021 (the “Affected Quarterly Periods”). Therefore, the Company, in consultation with its Audit Committee, concluded that the Affected Quarterly Periods should be restated to present all Class A common stock subject to possible redemption as temporary equity and to recognize accretion from the initial book value to redemption value at the time of its Initial Public Offering. As such, the Company is reporting these restatements to those periods in this quarterly report. The impact of the restatement on the financial statements for the Affected Quarterly Periods is presented below. The table below presents the effect of the financial statement adjustments related to the restatement discussed above of the Company’s previously reported unaudited condensed balance sheet as of March 31, 2021: As of March 31, 2021 (unaudited) As Reported Adjustment As Restated Total assets $ 231,036,262 $ — $ 231,036,262 Total liabilities $ 19,386,072 $ — $ 19,386,072 Class A common stock subject to possible redemption 206,650,180 23,349,820 230,000,000 Preferred stock — — — Class A common stock 233 (233) — Class B common stock 575 — 575 Additional paid-in capital 7,656,106 (7,656,106) — Accumulated deficit (2,656,904) (15,693,481) (18,350,385) Total stockholders’ equity (deficit) $ 5,000,010 $ (23,349,820) $ (18,349,810) Total Liabilities, Class A Common Stock Subject to Possible Redemption and Stockholders’ Equity (Deficit) $ 231,036,262 $ — $ 231,036,262 Shares of Class A common stock subject to possible redemption 20,665,018 2,334,982 23,000,000 Shares of Class A common stock 2,334,982 (2,334,982) — The impact on the unaudited condensed statement of stockholders’ equity is consistent with the changes to the impacted stockholders’ equity accounts described above.

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 Securities Exchange Act of 1934, as amended) 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 an election to opt out is irrevocable. We have 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, we, 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 unaudited condensed consolidated financial statements with those of 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 accountant standards used. Proposed Business Combination On June 28, 2021, the Company entered into an Agreement and Plan of Merger (as it may be amended, supplemented or otherwise modified from time to time, the “Merger Agreement”) by and among DFP, Orion Merger Sub I, Inc., a Delaware corporation and a direct, wholly-owned subsidiary of DFP (“First Merger Sub”), Orion Merger Sub II, LLC, a Delaware limited liability company and a direct, wholly-owned subsidiary of DFP (“Second Merger Sub”) and TOI Parent, Inc., a Delaware corporation (“TOI”). Refer to the Company’s Current Report on Form 8-K, and Proxy Statement/Prospectus filed with the SEC on June 29, 2021 and October 22, 2021, respectively. Use of Estimates The preparation of unaudited condensed consolidated financial statements in conformity with GAAP requires the Company’s 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 unaudited condensed consolidated financial statements and the reported amounts of revenue and expenses during the reporting period. Making estimates requires management to exercise significant judgment. It is at least reasonably possible that the estimate of the effect of a condition, situation or set of circumstances that existed at the date of the unaudited condensed consolidated financial statements, which management considered in formulating its estimate, could change in the near term due to one or more future confirming events. One of the more significant accounting estimates included in these unaudited condensed financial statements is the determination of the fair value of the derivative warrant liabilities. Accordingly, the actual results could differ significantly from those estimates. Concentration of Credit Risk Financial instruments that potentially subject the Company to concentrations of credit risk consist of cash accounts in a financial institution, which, at times, may exceed the Federal Deposit Insurance Corporation limit of $250,000, and investments held in Trust Account. The Company has not experienced losses on these accounts and management believes the Company is not exposed to significant risks on such accounts. Investments Held in Trust Account The Company’s portfolio of investments is comprised of 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 investments in money market funds that invest in U.S. government securities and generally have a readily determinable fair value, or a combination thereof. When the Company’s investments held in the Trust Account are comprised of U.S. government securities, the investments are classified as trading securities. When the Company’s investments held in the Trust Account are comprised of money market funds, the investments are recognized at fair value. Trading securities and investments in money market funds are presented on the balance sheets at fair value at the end of each reporting period. Gains and losses resulting from the change in fair value of these securities is included in interest income on investments held in the Trust Account in the accompanying unaudited condensed consolidated statements of operations. The estimated fair values of investments held in the Trust Account are determined using available market information. Cash and Cash Equivalents The Company considers all short-term investments with an original maturity of three months or less when purchased to be cash equivalents. The Company had no cash equivalents as of September 30, 2021 and December 31, 2020. Fair Value of Financial Instruments The fair value of the Company’s assets and liabilities which qualify as financial instruments under the FASB ASC Topic 820, “Fair Value Measurements,” equal or approximate the carrying amounts represented in the condensed consolidated balance sheets. Fair Value Measurements Fair value is defined as the price that would be received for sale of an asset or paid for transfer of a liability, in an orderly transaction between market participants at the measurement date. GAAP establishes a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). These tiers consist of: ● Level 1: Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities; ● Level 2: Quoted prices in markets that are not active or financial instruments for which significant inputs to models are observable (including but not limited to quoted prices for similar securities, interest rates, foreign exchange rates, volatility and credit risk), either directly or indirectly; ● Level 3: Prices or valuations that require significant unobservable inputs (including the Management’s assumptions in determining fair value measurement). In some circumstances, the inputs used to measure fair value might be categorized within different levels of the fair value hierarchy. In those instances, the fair value measurement is categorized in its entirety in the fair value hierarchy based on the lowest level input that is significant to the fair value measurement. As of September 30, 2021, the carrying values of cash, accounts payable, accrued expenses, prepaid expenses and franchise tax payable approximate their fair values due to the short-term nature of the instruments. The Company’s investments held in Trust Account are comprised of investments in U.S. Treasury securities with an original maturity of 185 days or less or investments in money market funds that comprise only U.S. Treasury securities and are recognized at fair value. The fair value of investments held in Trust Account is determined using quoted prices in active markets. Derivative Warrant Liabilities The Company does not use derivative instruments to hedge exposures to cash flow, market, or foreign currency risks. The Company evaluates all of its financial instruments, including issued stock purchase warrants, to determine if such instruments are derivatives or contain features that qualify as embedded derivatives, pursuant to ASC 480 and FASB ASC Topic 815, “Derivatives and Hedging” (“ASC 815”). The classification of derivative instruments, including whether such instruments should be recorded as liabilities or as equity, is re-assessed at the end of each reporting period. The 5,750,000 Public Warrants and the 3,733,334 Private Placement Warrants are recognized as derivative liabilities in accordance with ASC 815. Accordingly, the Company recognizes the warrant instruments as liabilities at fair value and adjusts the instruments to fair value at each reporting period. The liabilities are subject to re-measurement at each balance sheet date until exercised, and any change in fair value is recognized in the Company’s unaudited condensed consolidated statements of operations. The fair value of the Public Warrants issued in connection with the Public Offering and Private Placement Warrants were initially measured at fair value using a Monte Carlo simulation model and subsequently, the fair value of the Private Placement Warrants have been estimated using a Monte Carlo simulation model each measurement date. The fair value of Public Warrants issued in connection with the Initial Public Offering have subsequently been measured based on the listed market price of such warrants. Offering Costs Associated with the Initial Public Offering Offering costs consisted of legal, accounting, underwriting fees and other costs incurred through the Initial Public Offering that were directly related to the Initial Public Offering. Offering costs were allocated to the separable financial instruments issued in the Initial Public Offering based on a relative fair value basis, compared to total proceeds received. Offering costs associated with derivative warrant liabilities were expensed as incurred and presented as non-operating expenses in the condensed statements of operations. Offering costs associated with the Class A common stock issued were charged against the carrying value of the shares of Class A common stock upon the completion of the Initial Public Offering. The Company classifies deferred underwriting commissions as non-current liabilities as their liquidation is not reasonably expected to require the use of current assets or require the creation of current liabilities. Class A Common Stock Subject to Possible Redemption The Company accounts for its Class A common stock subject to possible redemption in accordance with the guidance in ASC Topic 480 “Distinguishing Liabilities from Equity.” Shares of Class A common stock subject to mandatory redemption (if any) are classified as liability instruments and are measured at fair value. Shares of conditionally redeemable Class A common stock (including Class A common stock that feature redemption rights that are either within the control of the holder or subject to redemption upon the occurrence of uncertain events not solely within the Company’s control) are classified as temporary equity. At all other times, shares of Class A common stock are classified as stockholders’ equity. The Company’s Class A common stock feature certain redemption rights that are considered to be outside of the Company’s control and subject to the occurrence of uncertain future events. Accordingly, as of September 30, 2021, and December 31, 2020, 23,000,000 shares of Class A common stock subject to possible redemption are presented as temporary equity, outside of the stockholders’ equity section of the Company’s condensed consolidated balance sheets. Under ASC 480-10-S99, the Company has elected to recognize changes in the redemption value immediately as they occur and adjust the carrying value of the security to equal the redemption value at the end of each reporting period. This method would view the end of the reporting period as if it were also the redemption date for the security. Effective with the closing of the Initial Public Offering, the Company recognized the accretion from initial book value to redemption amount, which resulted in charges against additional paid-in capital (to the extent available) and accumulated deficit. Net Income (Loss) Per Share of Common Stock The Company complies with accounting and disclosure requirements of FASB ASC Topic 260, “Earnings Per Share.” The Company has two classes of shares, which are referred to as Class A common stock and Class B common stock. Income and losses are shared pro rata between the two classes of shares. Net income (loss) per share of common stock is calculated by dividing the net income (loss) by the weighted average shares of common stock outstanding for the respective period. The calculation of diluted net income (loss) per share of common stock does not consider the effect of the warrants issued in connection with the Initial Public Offering and the Private Placement to purchase an aggregate of 9,483,334 shares of common stock in the calculation of diluted income (loss) per share, because their exercise is contingent upon future events and their inclusion would be anti-dilutive under the treasury stock method. As a result, diluted net income (loss) per share is the same as basic net income (loss) per share of common stock for the three and nine months ended September 30, 2021 and 2020. Accretion associated with the redeemable Class A common stock is excluded from earnings per share as the redemption value approximates fair value. The following table presents a reconciliation of the numerator and denominator used to compute basic and diluted net income (loss) per share for each class of common stock: For the Three Months Ended September 30, For the Nine Months Ended September 30 2021 2020 2021 2020 Class A Class B Class A Class B Class A Class B Class A Class B Basic and diluted net income (loss) per share of common stock: Numerator: Allocation of net income - basic $ (345,627) $ (86,407) $ (1,933,328) $ (483,332) $ (693,980) $ (173,495) $ (4,378,377) $ (1,433,857) Allocation of net income - diluted $ (345,627) $ (86,407) $ (1,933,328) $ (483,332) $ (693,980) $ (173,495) $ (4,340,374) $ (1,471,860) Denominator: Basic weighted average common shares outstanding 23,000,000 5,750,000 23,000,000 5,750,000 23,000,000 5,750,000 16,956,204 5,552,920 Diluted weighted average common shares outstanding 23,000,000 5,750,000 23,000,000 5,750,000 23,000,000 5,750,000 16,956,204 5,750,000 Basic net income (loss) per share of common stock $ (0.02) $ (0.02) $ (0.08) $ (0.08) $ (0.03) $ (0.03) $ (0.26) $ (0.26) Diluted net income (loss) per share of common stock $ (0.02) $ (0.02) $ (0.08) $ (0.08) $ (0.03) $ (0.03) $ (0.26) $ (0.26) Income Taxes The Company complies with the accounting and reporting requirements of Financial Accounting Standards Board Accounting Standard Codification, or ASC, 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. There were no unrecognized tax benefits as of September 30, 2021, and as of December 31, 2020. ASC 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 as income tax expense. No amounts were accrued for the payment of interest and penalties as of September 30, 2021, and December 31, 2020. The Company is currently not aware of any issues under review that could result in significant payments, accruals or material deviation from its position. The Company is subject to income tax examinations by major taxing authorities since inception. Recent Accounting Pronouncements In August 2020, the Financial Accounting Standards Board issued Accounting Standard Update (“ASU”) No. 2020-06, Debt—Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging—Contracts in Entity’s Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity The Company’s management does not believe that any other recently issued, but not yet effective, accounting standards updates, if currently adopted, would have a material effect on the accompanying unaudited condensed consolidated financial statements.	Note 3 — Summary of Significant Accounting Policies Basis of presentation The Company’s financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”) for financial information and pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). The Company has no subsidiaries. As described in Note 2—Restatement of Previously Issued Financial Statements, the Company’s financial statements for the period as of December 31, 2020, and the year ended December 31, 2020, as of September 30, 2020 and for the three and nine months ended September 30, 2020, as of June 30, 2020 and for the three and six months ended June 30, 2020, and as of March 31, 2020 and for the three months ended March 31, 2020 (collectively, the “2020 Affected Periods”), are restated in this Annual Report on Form 10-K/A (Amendment No. 2) (this “Annual Report”) to correct the misapplication of accounting guidance related to the redeemable Class A common stock and earnings per share in the Company’s previously issued audited and unaudited condensed financial statements for such periods. The restated financial statements are indicated as “Restated” in the audited and unaudited condensed financial statements and accompanying notes, as applicable. See Note 2—Restatement of Previously Issued Financial Statements for further discussion. Use of Estimates The preparation of the financial statements in conformity with GAAP requires the Company’s management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Making estimates requires management to exercise significant judgment. It is at least reasonably possible that the estimate of the effect of a condition, situation or set of circumstances that existed at the date of the financial statements, which management considered in formulating its estimate, could change in the near term due to one or more future conforming events. Accordingly, the actual results could differ from those estimates. Cash and Cash Equivalents The Company considers all short-term investments with an original maturity of three months or less when purchased to be cash equivalents. The Company had no cash equivalents as of December 31, 2020, and 2019. Investments Held in the Trust Account The Company’s portfolio of investments held in the Trust Account is comprised of 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 investments in money market funds that invest in U.S. government securities, or a combination thereof. The Company’s investments held in the Trust Account are classified as trading securities. Trading securities are presented on the balance sheet at fair value at the end of each reporting period. Gains and losses resulting from the change in fair value of these securities is included in net gain on investments, dividends and interest held in Trust Account in the accompanying statement of operations. The estimated fair values of investments held in the Trust Account were determined using available market information. Concentration of Credit Risk Financial instruments that potentially subject the Company to concentrations of credit risk consist of cash accounts in a financial institution, which, at times, may exceed the Federal Deposit Insurance Corporation limit of $250,000, and investments held in Trust Account. The Company has not experienced losses on these accounts and management believes the Company is not exposed to significant risks on such accounts. Fair Value of Financial Instruments Fair value is defined as the price that would be received for sale of an asset, or paid for transfer of a liability, in an orderly transaction between market participants at the measurement date. U.S. GAAP establishes a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). These tiers include: ● Level 1, defined as observable inputs such as quoted prices (unadjusted) for identical instruments in active markets; ● Level 2, defined as inputs other than quoted prices in active markets that are either directly or indirectly observable such as quoted prices for similar instruments in active markets or quoted prices for identical or similar instruments in markets that are not active; and ● Level 3, defined as unobservable inputs in which little or no market data exists, therefore requiring an entity to develop its own assumptions, such as valuations derived from valuation techniques in which one or more significant inputs or significant value drivers are unobservable. In some circumstances, the inputs used to measure fair value might be categorized within different levels of the fair value hierarchy. In those instances, the fair value measurement is categorized in its entirety in the fair value hierarchy based on the lowest level input that is significant to the fair value measurement. As of December 31, 2020, and 2019, the carrying values of cash, prepaid expenses, accounts payable, accrued expenses, accrued expenses - related party, and tax obligations approximate their fair values due to the short-term nature of the instruments. The Company’s portfolio of marketable securities held in the Trust Account is comprised mainly of investments in U.S. Treasury securities with an original maturity of 185 days or less. The fair value for trading securities is determined using quoted market prices in active markets. Offering Costs The Company complied with the requirements of the ASC 340-10-S99-1. Offering costs consist of legal, accounting, underwriting fees and other costs incurred that were directly attributable to the Initial Public Offering.. Offering costs are allocated to the separable financial instruments issued in the Initial Public Offering based on a relative fair value basis, compared to total proceeds received. Offering costs associated with warrant liabilities are expensed as incurred, presented as non-operating expenses in the statement of operations. Offering costs associated with the Public Shares were charged to the carrying value of the Class A common stock subject to possible redemption upon the completion of the Initial Public Offering. The Company classifies deferred underwriting commissions as their liquidation is not reasonably expected to require the use of current assets or require the creation of current liabilities. Derivative Warrant Liabilities The Company does not use derivative instruments to hedge its exposures to cash flow, market or foreign currency risks. Management evaluates all of the Company’s financial instruments, including issued warrants to purchase its Class A common stock, to determine if such instruments are derivatives or contain features that qualify as embedded derivatives, pursuant to ASC 480 and ASC 815-15. The classification of derivative instruments, including whether such instruments should be recorded as liabilities or as equity, is re-assessed at the end of each reporting period. The Company issued 5,750,000 warrants to purchase Class A common stock to investors in the Company’s Initial Public Offering, including the over-allotment, and simultaneously issued 3,733,334 Private Placement Warrants. All of the Company’s outstanding warrants are recognized as derivative liabilities in accordance with ASC 815-40. Accordingly, we recognize the warrant instruments as liabilities at fair value and adjust the instruments to fair value at each reporting period. The liabilities are subject to re-measurement at each balance sheet date until exercised, and any change in fair value is recognized in our statement of operations. The fair value of the Public Warrants issued in connection with the Public Offering and Private Placement Warrants were initially measured at fair value using a Monte Carlo simulation model and subsequently, the fair value of the Private Placement Warrants have been estimated using a Monte Carlo simulation model each measurement date. The fair value of Public Warrants issued in connection with the Initial Public Offering have subsequently been measured based on the listed market price of such warrants. Class A Common Stock Subject to Possible Redemption (Restated - See Note 2) The Company accounts for its Class A common stock subject to possible redemption in accordance with the guidance in ASC Topic 480 “Distinguishing Liabilities from Equity.” Class A common stock subject to mandatory redemption (if any) is classified as liability instruments and are measured at fair value. Conditionally redeemable Class A common stock (including Class A common stock that features redemption rights that are either within the control of the holder or subject to redemption upon the occurrence of uncertain events not solely within the Company’s control) are classified as temporary equity. At all other times, Class A common stock is classified as stockholders’ equity. The Company’s Class A common stock feature certain redemption rights that are considered to be outside of the Company’s control and subject to the occurrence of uncertain future events. Accordingly, as of December 31, 2020, 23,000,000 shares of Class A common stock subject to possible redemption are presented as temporary equity, outside of the stockholders’ equity section of the Company’s balance sheets. Under ASC 480-10-S99, the Company has elected to recognize changes in the redemption value immediately as they occur and adjust the carrying value of the security to equal the redemption value at the end of each reporting period. This method would view the end of the reporting period as if it were also the redemption date for the security. Accordingly, effective with the closing of the Initial Public Offering, the Company recognized the accretion from the initial book value to redemption amount, which resulted in charges against paid-in -capital (to the extent available) and accumulated deficit The Class A common stock subject to possible redemption reflected on the balance sheet is reconciled on the following table: Gross proceeds $ 230,000,000 Less: Amount allocated to Public Warrants (6,727,500) Class A common stock issuance costs (10,110,406) Plus: Accretion of carrying value to redemption value 16,837,906 Class A common stock subject to possible redemption $ 230,000,000 Net Income (Loss) Per Share of Common Stock The Company complies with accounting and disclosure requirements of FASB ASC Topic 260, “Earnings Per Share.” The Company has two classes of shares, which are referred to as Class A common stock and Class B common stock. Income and losses are shared pro rata between the two classes of shares. Net income (loss) per share of common stock is calculated by dividing the net income (loss) by the weighted average number of common stock outstanding for the respective period. The calculation of diluted net income (loss) per share of common stock does not consider the effect of the warrants underlying the Units sold in the Initial Public Offering and the Private Placement to purchase an aggregate of 9,483,334 of the Company’s Class A common stock in the calculation of diluted income per share, since their exercise is contingent upon future events and their inclusion would be anti-dilutive under the treasury stock method. Accretion associated with the redeemable Class A common stock is excluded from earnings per share as the redemption value approximates fair value. The table below presents a reconciliation of the numerator and denominator used to compute basic and diluted net loss per share of common stock for each class of common stock: For the Year Ended December 31, 2020 2019 Class A Class B Class A Class B Basic and diluted net income (loss) per share of common stock: Numerator: Allocation of net income $ (6,399,368) $ (1,940,536) $ — $ (2,300) Denominator: Basic and diluted weighted average common shares outstanding 18,475,410 5,602,459 — 5,000,000 Basic and diluted net income (loss) per share of common stock $ (0.35) $ (0.35) $ — $ — Income Taxes The Company complies with the accounting and reporting requirements of Financial Accounting Standards Board Accounting Standard Codification, or FASB ASC, 740, “Income Taxes,” which requires an asset and liability approach to financial accounting and reporting for income taxes.

The Company paid an underwriting discount of 2.0% of the per Unit offering price, or $3.6 million, at the closing of the Initial Public Offering, with an additional fee (the “Deferred Underwriting Fees”) of 3.5% of the gross offering proceeds, or $6.3 million, payable upon the Company’s completion of an Initial Business Combination. The Deferred Underwriting Fees will become payable to the underwriters from the amounts held in the Trust Account solely in the event the Company completes its initial Business Combination. Risks and uncertainties Management continues to evaluate the impact of the COVID-19 pandemic on its industry and has concluded that, while it is reasonably possible that the virus could have a negative effect on the Company’s financial position, results of its operations and/or close of the proposed transaction, the specific impact is not readily determinable as of the date of these unaudited condensed consolidated financial statements. The unaudited condensed consolidated financial statements do not include any adjustments that might result from the outcome of this uncertainty.	Note 6 — Commitments and Contingencies Registration Rights The initial stockholders and holders of the Private Placement Warrants are entitled to registration rights pursuant to a registration rights agreement. The initial stockholders and holders of the Private Placement Warrants will be entitled to make up to three demands, excluding short form registration demands, that the Company register such securities for sale under the Securities Act. In addition, these holders will have “piggy-back” registration rights to include their securities in other registration statements filed by the Company. The Company will bear the expenses incurred in connection with the filing of any such registration statements. Underwriting Agreement The Company granted the underwriters a 45-day option to purchase up to 3,000,000 additional Units to cover any over-allotments, at the initial public offering price less the underwriting discounts and commissions. The warrants that were issued in connection with the 3,000,000 over-allotment Units are identical to the public warrants and have no net cash settlement provisions. The underwriters exercised the over-allotment option in full on March 13, 2020. The underwriters did not receive any underwriting discounts or commission on the Units purchased by the Deerfield Funds. The Company paid an underwriting discount of 2.0% of the per Unit offering price, or $3.6 million, at the closing of the Initial Public Offering, with an additional fee (the “Deferred Underwriting Fees”) of 3.5% of the gross offering proceeds, or $6.3 million, payable upon the Company’s completion of an Initial Business Combination. The Deferred Underwriting Fees will become payable to the underwriters from the amounts held in the Trust Account solely in the event the Company completes its initial Business Combination. Risks and uncertainties Management continues to evaluate the impact of the COVID-19 pandemic on its industry and has concluded that, while it is reasonably possible that the virus could have a negative effect on the Company’s financial position, results of its operations and/or search for a target company, the specific impact is not readily determinable as of the date of these financial statements. The financial statements do not include any adjustments that might result from the outcome of this uncertainty.

The fair value of Public Warrants issued in connection with the Initial Public Offering are measured based on the listed market price of such warrants, a quoted price in an active market, a Level 1 measurement. The fair value of the Private Placement Warrants has been estimated using a Monte Carlo simulation model each measurement date. For the three months and nine months ended September 30, 2021, the Company recognized a gain resulting from a decrease in the fair value of the derivative warrant liabilities of approximately $1.1 For the three and nine months ended September 30, 2020, the Company recognized a loss of approximately $2.3 million and approximately $5.2 The estimated fair value of the Private Placement Warrants is determined using Level 3 inputs. Inherent in a Monte Carlo simulation are assumptions related to expected stock-price volatility, expected life, risk-free interest rate and dividend yield. The Company estimates the volatility of its common stock based on historical volatility of select peer companies that matches the expected remaining life of the warrants. The risk-free interest rate is based on the U.S. Treasury zero-coupon yield curve on the grant date for a maturity similar to the expected remaining life of the warrants.

Organization, Business Operations and Basis of Presentation	Sep. 30, 2021	Dec. 31, 2020
Description of the Business
Organization, Business Operations and Basis of Presentation	1. Organization, Business Operations. Incorporation The Oncology Institute, Inc., formerly DFP Healthcare Acquisitions Corp, (the “Company,” or “DFP”) was incorporated as a Delaware corporation on November 1, 2019. Sponsor The Company’s sponsor is DFP Sponsor LLC, a Delaware limited liability company (the “Sponsor”). Business Purpose The Company was formed for the purpose of effecting a merger, capital stock exchange, asset acquisition, stock purchase, reorganization or other similar business combination with one or more operating businesses (“Business Combination”). The Company has neither engaged in any operations nor generated revenue to date. As of September 30, 2021, the Company had not commenced any operations. All activity for the period from November 1, 2019 (inception) through September 30, 2021, relates to the Company’s formation and the initial public offering (the “Initial Public Offering”) described below, and since the Initial Public Offering, identifying a target company for a Business Combination. The Company will not generate any operating revenues until after the completion of its initial Business Combination, at the earliest. The Company generates non-operating income in the form of interest income on cash and cash equivalents from the proceeds derived from the Initial Public Offering. The Company’s management has broad discretion with respect to the specific application of the net proceeds of its Initial Public Offering, although substantially all of the net proceeds of the Initial Public Offering are intended to be generally applied toward completing a Business Combination. Furthermore, there is no assurance that the Company will be able to successfully complete a Business Combination. Financing The registration statement for the Company’s Initial Public Offering was declared effective by the Securities and Exchange Commission (the “SEC”) on March 10, 2020. On March 13, 2020, the Company consummated its Initial Public Offering of 23,000,000 units (the “Units” and, with respect to the Class A common stock included in the Units being offered, the “Public Shares”), including 3,000,000 additional Units to cover over-allotments (the “Over-Allotment Units”), at $10.00 per Unit, generating gross proceeds of $230.0 million, and incurring offering costs of approximately $10.4 million, inclusive of approximately $6.3 million in deferred underwriting commissions (Note 3). Simultaneously with the closing of the Initial Public Offering, the Company consummated the private placement (“Private Placement”) of 3,733,334 warrants (each, a “Private Placement Warrant” and collectively, the “Private Placement Warrants”) at a price of $1.50 per Private Placement Warrant in a private placement to the Sponsor, generating proceeds of $5.6 million (Note 4). Trust Account Upon the closing of the Initial Public Offering and the Private Placement, $230.0 million ($10.00 per Unit) of the net proceeds of the Initial Public Offering and certain of the proceeds of the Private Placement was placed in a trust account (the “Trust Account”) and invested in permitted United States “government securities” within the meaning of Section 2(a)(16) of the Investment Company Act of 1940, as amended, which the Company refers to as the Investment Company Act, having a maturity of 185 days or less or in money market funds meeting certain conditions under Rule 2a-7 promulgated under the Investment Company Act that invest only in direct U.S. government treasury obligations. The Company’s second amended and restated certificate of incorporation provides that, other than the withdrawal of interest earned on the funds that may be released to the Company to pay taxes, none of the funds held in Trust Account will be released until the earlier of: (i) the completion of the Business Combination; (ii) the redemption of the Public Shares to its holders (the “Public Stockholders”) properly tendered in connection with a stockholder vote to amend the Company’s second amended and restated certificate of incorporation to modify the substance or timing of the Company’s obligation to redeem 100% of the Public Shares or with respect to any other material provision relating to stockholders’ rights or pre-initial Business Combination activity, or (iii) the redemption of 100% of the Public Shares if the Company does not complete a Business Combination within 24 months from the closing of the Initial Public Offering. The Company, after signing a definitive agreement for a Business Combination, will either (i) seek stockholder approval of the Business Combination at a meeting called for such purpose in connection with which stockholders may seek to redeem their shares, regardless of whether they vote for or against the Business Combination, for cash equal to their pro rata share of the aggregate amount then on deposit in the Trust Account calculated as of two two If the Company holds a stockholder vote in connection with a Business Combination, a Public Stockholder will have the right to redeem its shares for an amount in cash equal to their pro rata share of the aggregate amount then on deposit in the Trust Account calculated as of two business days prior to the consummation of the initial Business Combination, including interest earned on the funds held in the Trust Account and not previously released to the Company to fund its working capital requirements (subject to an annual limit of $500,000) and/or to pay its taxes. As a result, such common stock is recorded at redemption amount and classified as temporary equity upon the completion of the Initial Public Offering, in accordance with ASC 480, “Distinguishing Liabilities from Equity.” The amount in the Trust Account is initially anticipated to be $10.00 per public share ($230.0 million held in the Trust Account divided by 23,000,000 public shares). The Company will have 24 months from the closing of the Initial Public Offering, or until March 13, 2022, to complete its initial Business Combination (the “ Combination Period”). If the Company does not complete a Business Combination within this period of time, it will (i) cease all operations except for the purposes of winding up; (ii) as promptly as reasonably possible, but not more than ten Going Concern As of September 30, 2021, the Company had approximately $0.2 million in its operating bank account and a working capital deficit of approximately $3.3 million. The Company’s liquidity needs to date have been satisfied through a $25,000 contribution from the Sponsor in exchange for the issuance of the Founder Shares to the Sponsor, the Note (defined below) of $200,000 from the Sponsor, and the proceeds from the consummation of the Private Placement not held in the Trust Account. On March 13, 2020, the Company repaid the Note in full to the Sponsor. In addition, in order to finance transaction costs in connection with a Business Combination, the Sponsor or an affiliate of the Sponsor, or certain of the Company’s officers and directors may, but are not obligated to, provide the Company with Working Capital Loans (see Note 4). As of September 30, 2021, and December 31, 2020, there were no Working Capital Loans outstanding. In connection with the Company’s assessment of going concern considerations in accordance with ASC Topic 205-40, “Presentation of Financial Statements - Going Concern,” management has determined that the liquidity condition and date for mandatory liquidation and subsequent dissolution raise substantial doubt about the Company’s ability to continue as a going concern. No adjustments have been made to the carrying amounts of assets or liabilities should the Company be required to liquidate after March 13, 2022.	Note 1 — Organization, Business Operations and Basis of Presentation Incorporation DFP Healthcare Acquisitions Corp., predecessor to The Oncology Institute, Inc. (the “Company”) was incorporated as a Delaware corporation on November 1, 2019. Sponsor The Company’s sponsor is DFP Sponsor LLC, a Delaware limited liability company (the “Sponsor”). Business Purpose The Company was formed for the purpose of effecting a merger, capital stock exchange, asset acquisition, stock purchase, reorganization or other similar business combination with one or more operating businesses that it has not yet selected (“Business Combination”). The Company has neither engaged in any operations nor generated revenue to date. As of December 31, 2020, the Company had not commenced any operations.

If the Company does not complete a Business Combination within this period of time, it will (i) cease all operations except for the purposes of winding up; (ii) as promptly as reasonably possible, but not more than ten Basis of Presentation The accompanying financial statements of the Company have been prepared in accordance with United States generally accepted accounting principles (“U.S. GAAP”) and pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). Emerging Growth Company The Company is an “emerging growth company,” as defined in Section 2(a) of the Securities Act of 1933, as amended (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 stockholder approval of any golden parachute payments not previously approved. Further, section 102(b)(1) of the JOBS Act exempts emerging growth companies from being required to comply with new or revised financial accounting standards until private companies (that is, those that have not had a Securities Act registration statement declared effective or do not have a class of securities registered under the Securities Exchange Act of 1934, as amended) 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 an election to opt out is irrevocable. We have 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, we, 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 accountant standards used.

Restatement of previously issue

Restatement of previously issued financial statements	Dec. 31, 2020
Restatement of previously issued financial statements
Restatement of previously issued financial statements	Note 2 — Restatement of Previously Issued Financial Statements The Company concluded it should restate its previously issued financial statements by amending Amendment No. 1 to its Annual Report on Form 10-K/A, filed with the SEC on May 24, 2021, to classify all Class A common stock subject to possible redemption in temporary equity. In accordance with accounting guidance on redeemable equity instruments, ASC 480, paragraph 10-S99, redemption provisions not solely within the control of the Company require common stock subject to redemption to be classified outside of permanent equity. The Company had previously classified a portion of its Class A common stock in permanent equity, or total stockholders’ equity. Although the Company did not specify a maximum redemption threshold, its charter currently provides that, the Company will not redeem its public shares in an amount that would cause its net tangible assets to be less than $5,000,001. Previously, the Company did not consider redeemable stock classified as temporary equity as part of net tangible assets. Effective with these financial statements, the Company revised this interpretation to include temporary equity in net tangible assets. Also, in connection with the change in presentation for the Class A common stock subject to possible redemption, the Company also restated its earnings per share calculation to allocate income and losses shared pro rata between the two classes of shares. This presentation contemplates a Business Combination as the most likely outcome, in which case, both classes of shares share pro rata in the income and losses of the Company. As a result, the Company restated its previously filed financial statements to present all redeemable Class A common stock as temporary equity and to recognize accretion from the initial book value to redemption value at the time of its Initial Public Offering and in accordance with ASC 480. The Company’s previously filed financial statements that contained the error were initially reported in the Company’s Form 8-K filed with the SEC on March 13, 2020 (the “Post-IPO Balance Sheet”), the Company’s Form 10-Qs for the quarterly periods ended March 31, 2020, June 30, 2020, and September 30, 2020, and the Company’s Annual Report on 10-K for the annual period ended December 31, 2020, which were all previously restated in the Company’s Amendment No. 1 to its Form 10-K as filed with the SEC on May 12, 2021 (“the 2020 Affected Periods”), as well as the Company’s Form 10-Qs for the quarterly periods ended March 31, 2021, and June 30, 2021 (collectively, the “Affected Periods”). These financial statements restate the Company’s previously issued audited and unaudited financial statements covering the periods through December 31, 2020. The quarterly periods ended March 31, 2021, and June 30, 2021, will be restated with an amendment the Company’s Form 10-Q for the quarterly period ended September 30, 2021. Impact of the Restatement The impact of the restatement on the balance sheet, statement of operations and statement of cash flows for the 2020 Affected Periods is presented below: As Previously Restated on 10-K/A As of March 13, 2020 Amendment No. 1 Adjustment As Restated Total assets $ 231,769,236 $ — $ 231,769,236 Total liabilities $ 17,812,302 $ — $ 17,812,302 Class A common stock subject to possible redemption 208,956,930 21,043,070 230,000,000 Preferred stock — — — Class A common stock 210 (210) — Class B common stock 575 — 575 Additional paid-in capital 5,356,051 (5,356,051) — Accumulated deficit (356,832) (15,686,809) (16,043,641) Total stockholders’ equity (deficit) $ 5,000,004 $ (21,043,070) $ (16,043,066) Total Liabilities, Class A Common Stock Subject to Possible Redemption and Stockholders’ Equity (Deficit) $ 231,769,236 $ — $ 231,769,236 Shares of Class A common stock subject to possible redemption 20,895,693 2,104,307 23,000,000 Shares of Class A common stock 2,104,307 (2,104,307) — As Previously Restated on 10-K/A As of December 31,2020 Amendment No. 1 Adjustment As Restated Total assets $ 231,323,610 $ — $ 231,323,610 Total liabilities $ 25,358,720 $ — $ 25,358,720 Class A common stock subject to possible redemption 200,964,880 29,035,120 230,000,000 Preferred stock — — — Class A common stock 290 (290) — Class B common stock 575 — 575 Additional paid-in capital 13,341,349 (13,341,349) — Accumulated deficit (8,342,204) (15,693,481) (24,035,685) Total stockholders’ equity (deficit) $ 5,000,010 $ (29,035,120) $ (24,035,110) Total Liabilities, Class A Common Stock Subject to Possible Redemption and Stockholders’ Equity (Deficit) $ 231,323,610 $ — $ 231,323,610 Shares of Class A common stock subject to possible redemption 20,096,488 2,903,512 23,000,000 Shares of Class A common stock 2,903,512 (2,903,512) — The impact of the restatement on the statement of stockholders’ equity is consistent with the changes to the impacted stockholders’ equity accounts described above.

Summary of Significant Accounting Policies
Summary of Significant Accounting Policies	2. Basis of Presentation and Significant Accounting Policies. Basis of Presentation and Principles of Consolidation The accompanying unaudited condensed consolidated financial statements are presented in U.S. dollars in conformity with accounting principles generally accepted in the United States of America (“GAAP”) for financial information and pursuant to the rules and regulations of the SEC. Accordingly, they do not include all of the information and footnotes required by GAAP. In the opinion of management, the unaudited condensed consolidated financial statements reflect all adjustments, which include only normal recurring adjustments necessary for the fair statement of the balances and results for the period presented. Operating results for the period for the three and nine months ended September 30, 2021, are not necessarily indicative of the results that may be expected for the period ending December 31, 2021. The unaudited condensed consolidated financial statements of the Company include its wholly owned subsidiaries in connection with the proposed business combination (as described below). All inter-company accounts and transactions are eliminated in consolidation. The accompanying unaudited condensed consolidated financial statements should be read in conjunction with the audited financial statements and notes thereto included in the Form 10-K/A filed by the Company with the SEC on May 24, 2021. Restatement of Previously Reported Financial Statements In preparation of the Company’s unaudited condensed financial statements for the quarterly period ended September 30, 2021, the Company concluded it should restate its previously issued financial statements to classify all Class A common stock subject to possible redemption in temporary equity. In accordance with technical accounting guidance on redeemable equity instruments in ASC 480-10-S99, redemption provisions not solely within the control of the Company, require Class A common stock subject to redemption to be classified outside of permanent equity. The Company had previously classified a portion of its Class A common stock in permanent equity. Although the Company did not specify a maximum redemption threshold, its charter currently provides that the Company will not redeem its Public Shares in an amount that would cause its net tangible assets to be less than $5,000,001. Previously, the Company did not consider redeemable shares classified as temporary equity as part of net tangible assets. Effective with these condensed financial statements, the Company revised this interpretation to include temporary equity in net tangible assets. In connection with the change in presentation for the Class A common stock subject to possible redemption, the Company restated its earnings per share calculation to allocate income and losses shared pro rata between the two classes of shares. This presentation contemplates a Business Combination as the most likely outcome, in which case, both classes of shares participate pro rata in the income and losses of the Company. In accordance with SEC Staff Accounting Bulletin No. 99, “Materiality,” and SEC Staff Accounting Bulletin No. 108, “Considering the Effects of Prior Year Misstatements when Quantifying Misstatements in Current Year Financial Statements,” the Company evaluated the corrections and has determined that the related impact was material to the previously filed financial statements that contained the error, reported in the Company’s Quarterly Reports on Form 10-Q for the quarterly periods ended March 31, 2021 and June 30, 2021 (the “Affected Quarterly Periods”). Therefore, the Company, in consultation with its Audit Committee, concluded that the Affected Quarterly Periods should be restated to present all Class A common stock subject to possible redemption as temporary equity and to recognize accretion from the initial book value to redemption value at the time of its Initial Public Offering.

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 Securities Exchange Act of 1934, as amended) 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 an election to opt out is irrevocable. We have 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, we, 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 unaudited condensed consolidated financial statements with those of 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 accountant standards used. Proposed Business Combination On June 28, 2021, the Company entered into an Agreement and Plan of Merger (as it may be amended, supplemented or otherwise modified from time to time, the “Merger Agreement”) by and among DFP, Orion Merger Sub I, Inc., a Delaware corporation and a direct, wholly-owned subsidiary of DFP (“First Merger Sub”), Orion Merger Sub II, LLC, a Delaware limited liability company and a direct, wholly-owned subsidiary of DFP (“Second Merger Sub”) and TOI Parent, Inc., a Delaware corporation (“TOI”). Refer to the Company’s Current Report on Form 8-K, and Proxy Statement/Prospectus filed with the SEC on June 29, 2021 and October 22, 2021, respectively. Use of Estimates The preparation of unaudited condensed consolidated financial statements in conformity with GAAP requires the Company’s 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 unaudited condensed consolidated financial statements and the reported amounts of revenue and expenses during the reporting period. Making estimates requires management to exercise significant judgment. It is at least reasonably possible that the estimate of the effect of a condition, situation or set of circumstances that existed at the date of the unaudited condensed consolidated financial statements, which management considered in formulating its estimate, could change in the near term due to one or more future confirming events. One of the more significant accounting estimates included in these unaudited condensed financial statements is the determination of the fair value of the derivative warrant liabilities. Accordingly, the actual results could differ significantly from those estimates. Concentration of Credit Risk Financial instruments that potentially subject the Company to concentrations of credit risk consist of cash accounts in a financial institution, which, at times, may exceed the Federal Deposit Insurance Corporation limit of $250,000, and investments held in Trust Account. The Company has not experienced losses on these accounts and management believes the Company is not exposed to significant risks on such accounts. Investments Held in Trust Account The Company’s portfolio of investments is comprised of 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 investments in money market funds that invest in U.S. government securities and generally have a readily determinable fair value, or a combination thereof. When the Company’s investments held in the Trust Account are comprised of U.S. government securities, the investments are classified as trading securities. When the Company’s investments held in the Trust Account are comprised of money market funds, the investments are recognized at fair value. Trading securities and investments in money market funds are presented on the balance sheets at fair value at the end of each reporting period. Gains and losses resulting from the change in fair value of these securities is included in interest income on investments held in the Trust Account in the accompanying unaudited condensed consolidated statements of operations. The estimated fair values of investments held in the Trust Account are determined using available market information. Cash and Cash Equivalents The Company considers all short-term investments with an original maturity of three months or less when purchased to be cash equivalents. The Company had no cash equivalents as of September 30, 2021 and December 31, 2020. Fair Value of Financial Instruments The fair value of the Company’s assets and liabilities which qualify as financial instruments under the FASB ASC Topic 820, “Fair Value Measurements,” equal or approximate the carrying amounts represented in the condensed consolidated balance sheets. Fair Value Measurements Fair value is defined as the price that would be received for sale of an asset or paid for transfer of a liability, in an orderly transaction between market participants at the measurement date. GAAP establishes a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). These tiers consist of: ● Level 1: Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities; ● Level 2: Quoted prices in markets that are not active or financial instruments for which significant inputs to models are observable (including but not limited to quoted prices for similar securities, interest rates, foreign exchange rates, volatility and credit risk), either directly or indirectly; ● Level 3: Prices or valuations that require significant unobservable inputs (including the Management’s assumptions in determining fair value measurement). In some circumstances, the inputs used to measure fair value might be categorized within different levels of the fair value hierarchy. In those instances, the fair value measurement is categorized in its entirety in the fair value hierarchy based on the lowest level input that is significant to the fair value measurement. As of September 30, 2021, the carrying values of cash, accounts payable, accrued expenses, prepaid expenses and franchise tax payable approximate their fair values due to the short-term nature of the instruments. The Company’s investments held in Trust Account are comprised of investments in U.S. Treasury securities with an original maturity of 185 days or less or investments in money market funds that comprise only U.S. Treasury securities and are recognized at fair value. The fair value of investments held in Trust Account is determined using quoted prices in active markets. Derivative Warrant Liabilities The Company does not use derivative instruments to hedge exposures to cash flow, market, or foreign currency risks. The Company evaluates all of its financial instruments, including issued stock purchase warrants, to determine if such instruments are derivatives or contain features that qualify as embedded derivatives, pursuant to ASC 480 and FASB ASC Topic 815, “Derivatives and Hedging” (“ASC 815”). The classification of derivative instruments, including whether such instruments should be recorded as liabilities or as equity, is re-assessed at the end of each reporting period. The 5,750,000 Public Warrants and the 3,733,334 Private Placement Warrants are recognized as derivative liabilities in accordance with ASC 815. Accordingly, the Company recognizes the warrant instruments as liabilities at fair value and adjusts the instruments to fair value at each reporting period. The liabilities are subject to re-measurement at each balance sheet date until exercised, and any change in fair value is recognized in the Company’s unaudited condensed consolidated statements of operations. The fair value of the Public Warrants issued in connection with the Public Offering and Private Placement Warrants were initially measured at fair value using a Monte Carlo simulation model and subsequently, the fair value of the Private Placement Warrants have been estimated using a Monte Carlo simulation model each measurement date. The fair value of Public Warrants issued in connection with the Initial Public Offering have subsequently been measured based on the listed market price of such warrants. Offering Costs Associated with the Initial Public Offering Offering costs consisted of legal, accounting, underwriting fees and other costs incurred through the Initial Public Offering that were directly related to the Initial Public Offering. Offering costs were allocated to the separable financial instruments issued in the Initial Public Offering based on a relative fair value basis, compared to total proceeds received. Offering costs associated with derivative warrant liabilities were expensed as incurred and presented as non-operating expenses in the condensed statements of operations. Offering costs associated with the Class A common stock issued were charged against the carrying value of the shares of Class A common stock upon the completion of the Initial Public Offering. The Company classifies deferred underwriting commissions as non-current liabilities as their liquidation is not reasonably expected to require the use of current assets or require the creation of current liabilities. Class A Common Stock Subject to Possible Redemption The Company accounts for its Class A common stock subject to possible redemption in accordance with the guidance in ASC Topic 480 “Distinguishing Liabilities from Equity.” Shares of Class A common stock subject to mandatory redemption (if any) are classified as liability instruments and are measured at fair value. Shares of conditionally redeemable Class A common stock (including Class A common stock that feature redemption rights that are either within the control of the holder or subject to redemption upon the occurrence of uncertain events not solely within the Company’s control) are classified as temporary equity. At all other times, shares of Class A common stock are classified as stockholders’ equity. The Company’s Class A common stock feature certain redemption rights that are considered to be outside of the Company’s control and subject to the occurrence of uncertain future events. Accordingly, as of September 30, 2021, and December 31, 2020, 23,000,000 shares of Class A common stock subject to possible redemption are presented as temporary equity, outside of the stockholders’ equity section of the Company’s condensed consolidated balance sheets. Under ASC 480-10-S99, the Company has elected to recognize changes in the redemption value immediately as they occur and adjust the carrying value of the security to equal the redemption value at the end of each reporting period. This method would view the end of the reporting period as if it were also the redemption date for the security. Effective with the closing of the Initial Public Offering, the Company recognized the accretion from initial book value to redemption amount, which resulted in charges against additional paid-in capital (to the extent available) and accumulated deficit. Net Income (Loss) Per Share of Common Stock The Company complies with accounting and disclosure requirements of FASB ASC Topic 260, “Earnings Per Share.” The Company has two classes of shares, which are referred to as Class A common stock and Class B common stock. Income and losses are shared pro rata between the two classes of shares. Net income (loss) per share of common stock is calculated by dividing the net income (loss) by the weighted average shares of common stock outstanding for the respective period. The calculation of diluted net income (loss) per share of common stock does not consider the effect of the warrants issued in connection with the Initial Public Offering and the Private Placement to purchase an aggregate of 9,483,334 shares of common stock in the calculation of diluted income (loss) per share, because their exercise is contingent upon future events and their inclusion would be anti-dilutive under the treasury stock method. As a result, diluted net income (loss) per share is the same as basic net income (loss) per share of common stock for the three and nine months ended September 30, 2021 and 2020. Accretion associated with the redeemable Class A common stock is excluded from earnings per share as the redemption value approximates fair value. The following table presents a reconciliation of the numerator and denominator used to compute basic and diluted net income (loss) per share for each class of common stock: For the Three Months Ended September 30, For the Nine Months Ended September 30 2021 2020 2021 2020 Class A Class B Class A Class B Class A Class B Class A Class B Basic and diluted net income (loss) per share of common stock: Numerator: Allocation of net income - basic $ (345,627) $ (86,407) $ (1,933,328) $ (483,332) $ (693,980) $ (173,495) $ (4,378,377) $ (1,433,857) Allocation of net income - diluted $ (345,627) $ (86,407) $ (1,933,328) $ (483,332) $ (693,980) $ (173,495) $ (4,340,374) $ (1,471,860) Denominator: Basic weighted average common shares outstanding 23,000,000 5,750,000 23,000,000 5,750,000 23,000,000 5,750,000 16,956,204 5,552,920 Diluted weighted average common shares outstanding 23,000,000 5,750,000 23,000,000 5,750,000 23,000,000 5,750,000 16,956,204 5,750,000 Basic net income (loss) per share of common stock $ (0.02) $ (0.02) $ (0.08) $ (0.08) $ (0.03) $ (0.03) $ (0.26) $ (0.26) Diluted net income (loss) per share of common stock $ (0.02) $ (0.02) $ (0.08) $ (0.08) $ (0.03) $ (0.03) $ (0.26) $ (0.26) Income Taxes The Company complies with the accounting and reporting requirements of Financial Accounting Standards Board Accounting Standard Codification, or ASC, 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. There were no unrecognized tax benefits as of September 30, 2021, and as of December 31, 2020. ASC 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 as income tax expense. No amounts were accrued for the payment of interest and penalties as of September 30, 2021, and December 31, 2020. The Company is currently not aware of any issues under review that could result in significant payments, accruals or material deviation from its position. The Company is subject to income tax examinations by major taxing authorities since inception. Recent Accounting Pronouncements In August 2020, the Financial Accounting Standards Board issued Accounting Standard Update (“ASU”) No. 2020-06, Debt—Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging—Contracts in Entity’s Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity The Company’s management does not believe that any other recently issued, but not yet effective, accounting standards updates, if currently adopted, would have a material effect on the accompanying unaudited condensed consolidated financial statements.	Note 3 — Summary of Significant Accounting Policies Basis of presentation The Company’s financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”) for financial information and pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). The Company has no subsidiaries. As described in Note 2—Restatement of Previously Issued Financial Statements, the Company’s financial statements for the period as of December 31, 2020, and the year ended December 31, 2020, as of September 30, 2020 and for the three and nine months ended September 30, 2020, as of June 30, 2020 and for the three and six months ended June 30, 2020, and as of March 31, 2020 and for the three months ended March 31, 2020 (collectively, the “2020 Affected Periods”), are restated in this Annual Report on Form 10-K/A (Amendment No. 2) (this “Annual Report”) to correct the misapplication of accounting guidance related to the redeemable Class A common stock and earnings per share in the Company’s previously issued audited and unaudited condensed financial statements for such periods. The restated financial statements are indicated as “Restated” in the audited and unaudited condensed financial statements and accompanying notes, as applicable. See Note 2—Restatement of Previously Issued Financial Statements for further discussion. Use of Estimates The preparation of the financial statements in conformity with GAAP requires the Company’s management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Making estimates requires management to exercise significant judgment. It is at least reasonably possible that the estimate of the effect of a condition, situation or set of circumstances that existed at the date of the financial statements, which management considered in formulating its estimate, could change in the near term due to one or more future conforming events. Accordingly, the actual results could differ from those estimates. Cash and Cash Equivalents The Company considers all short-term investments with an original maturity of three months or less when purchased to be cash equivalents. The Company had no cash equivalents as of December 31, 2020, and 2019. Investments Held in the Trust Account The Company’s portfolio of investments held in the Trust Account is comprised of 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 investments in money market funds that invest in U.S. government securities, or a combination thereof. The Company’s investments held in the Trust Account are classified as trading securities. Trading securities are presented on the balance sheet at fair value at the end of each reporting period. Gains and losses resulting from the change in fair value of these securities is included in net gain on investments, dividends and interest held in Trust Account in the accompanying statement of operations. The estimated fair values of investments held in the Trust Account were determined using available market information. Concentration of Credit Risk Financial instruments that potentially subject the Company to concentrations of credit risk consist of cash accounts in a financial institution, which, at times, may exceed the Federal Deposit Insurance Corporation limit of $250,000, and investments held in Trust Account. The Company has not experienced losses on these accounts and management believes the Company is not exposed to significant risks on such accounts. Fair Value of Financial Instruments Fair value is defined as the price that would be received for sale of an asset, or paid for transfer of a liability, in an orderly transaction between market participants at the measurement date. U.S. GAAP establishes a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). These tiers include: ● Level 1, defined as observable inputs such as quoted prices (unadjusted) for identical instruments in active markets; ● Level 2, defined as inputs other than quoted prices in active markets that are either directly or indirectly observable such as quoted prices for similar instruments in active markets or quoted prices for identical or similar instruments in markets that are not active; and ● Level 3, defined as unobservable inputs in which little or no market data exists, therefore requiring an entity to develop its own assumptions, such as valuations derived from valuation techniques in which one or more significant inputs or significant value drivers are unobservable. In some circumstances, the inputs used to measure fair value might be categorized within different levels of the fair value hierarchy. In those instances, the fair value measurement is categorized in its entirety in the fair value hierarchy based on the lowest level input that is significant to the fair value measurement. As of December 31, 2020, and 2019, the carrying values of cash, prepaid expenses, accounts payable, accrued expenses, accrued expenses - related party, and tax obligations approximate their fair values due to the short-term nature of the instruments. The Company’s portfolio of marketable securities held in the Trust Account is comprised mainly of investments in U.S. Treasury securities with an original maturity of 185 days or less. The fair value for trading securities is determined using quoted market prices in active markets. Offering Costs The Company complied with the requirements of the ASC 340-10-S99-1. Offering costs consist of legal, accounting, underwriting fees and other costs incurred that were directly attributable to the Initial Public Offering.. Offering costs are allocated to the separable financial instruments issued in the Initial Public Offering based on a relative fair value basis, compared to total proceeds received. Offering costs associated with warrant liabilities are expensed as incurred, presented as non-operating expenses in the statement of operations. Offering costs associated with the Public Shares were charged to the carrying value of the Class A common stock subject to possible redemption upon the completion of the Initial Public Offering. The Company classifies deferred underwriting commissions as their liquidation is not reasonably expected to require the use of current assets or require the creation of current liabilities. Derivative Warrant Liabilities The Company does not use derivative instruments to hedge its exposures to cash flow, market or foreign currency risks. Management evaluates all of the Company’s financial instruments, including issued warrants to purchase its Class A common stock, to determine if such instruments are derivatives or contain features that qualify as embedded derivatives, pursuant to ASC 480 and ASC 815-15. The classification of derivative instruments, including whether such instruments should be recorded as liabilities or as equity, is re-assessed at the end of each reporting period. The Company issued 5,750,000 warrants to purchase Class A common stock to investors in the Company’s Initial Public Offering, including the over-allotment, and simultaneously issued 3,733,334 Private Placement Warrants. All of the Company’s outstanding warrants are recognized as derivative liabilities in accordance with ASC 815-40. Accordingly, we recognize the warrant instruments as liabilities at fair value and adjust the instruments to fair value at each reporting period. The liabilities are subject to re-measurement at each balance sheet date until exercised, and any change in fair value is recognized in our statement of operations. The fair value of the Public Warrants issued in connection with the Public Offering and Private Placement Warrants were initially measured at fair value using a Monte Carlo simulation model and subsequently, the fair value of the Private Placement Warrants have been estimated using a Monte Carlo simulation model each measurement date. The fair value of Public Warrants issued in connection with the Initial Public Offering have subsequently been measured based on the listed market price of such warrants. Class A Common Stock Subject to Possible Redemption (Restated - See Note 2) The Company accounts for its Class A common stock subject to possible redemption in accordance with the guidance in ASC Topic 480 “Distinguishing Liabilities from Equity.” Class A common stock subject to mandatory redemption (if any) is classified as liability instruments and are measured at fair value. Conditionally redeemable Class A common stock (including Class A common stock that features redemption rights that are either within the control of the holder or subject to redemption upon the occurrence of uncertain events not solely within the Company’s control) are classified as temporary equity. At all other times, Class A common stock is classified as stockholders’ equity. The Company’s Class A common stock feature certain redemption rights that are considered to be outside of the Company’s control and subject to the occurrence of uncertain future events. Accordingly, as of December 31, 2020, 23,000,000 shares of Class A common stock subject to possible redemption are presented as temporary equity, outside of the stockholders’ equity section of the Company’s balance sheets. Under ASC 480-10-S99, the Company has elected to recognize changes in the redemption value immediately as they occur and adjust the carrying value of the security to equal the redemption value at the end of each reporting period. This method would view the end of the reporting period as if it were also the redemption date for the security. Accordingly, effective with the closing of the Initial Public Offering, the Company recognized the accretion from the initial book value to redemption amount, which resulted in charges against paid-in -capital (to the extent available) and accumulated deficit The Class A common stock subject to possible redemption reflected on the balance sheet is reconciled on the following table: Gross proceeds $ 230,000,000 Less: Amount allocated to Public Warrants (6,727,500) Class A common stock issuance costs (10,110,406) Plus: Accretion of carrying value to redemption value 16,837,906 Class A common stock subject to possible redemption $ 230,000,000 Net Income (Loss) Per Share of Common Stock The Company complies with accounting and disclosure requirements of FASB ASC Topic 260, “Earnings Per Share.” The Company has two classes of shares, which are referred to as Class A common stock and Class B common stock. Income and losses are shared pro rata between the two classes of shares. Net income (loss) per share of common stock is calculated by dividing the net income (loss) by the weighted average number of common stock outstanding for the respective period. The calculation of diluted net income (loss) per share of common stock does not consider the effect of the warrants underlying the Units sold in the Initial Public Offering and the Private Placement to purchase an aggregate of 9,483,334 of the Company’s Class A common stock in the calculation of diluted income per share, since their exercise is contingent upon future events and their inclusion would be anti-dilutive under the treasury stock method. Accretion associated with the redeemable Class A common stock is excluded from earnings per share as the redemption value approximates fair value. The table below presents a reconciliation of the numerator and denominator used to compute basic and diluted net loss per share of common stock for each class of common stock: For the Year Ended December 31, 2020 2019 Class A Class B Class A Class B Basic and diluted net income (loss) per share of common stock: Numerator: Allocation of net income $ (6,399,368) $ (1,940,536) $ — $ (2,300) Denominator: Basic and diluted weighted average common shares outstanding 18,475,410 5,602,459 — 5,000,000 Basic and diluted net income (loss) per share of common stock $ (0.35) $ (0.35) $ — $ — Income Taxes The Company complies with the accounting and reporting requirements of Financial Accounting Standards Board Accounting Standard Codification, or FASB ASC, 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. There were no unrecognized tax benefits as of December 31, 2020 or 2019. FASB ASC 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 as income tax expense. No amounts were accrued for the payment of interest and penalties as of December 31, 2020 or 2019. The Company is currently not aware of any issues under review that could result in significant payments, accruals or material deviation from its position. The Company is subject to income tax examinations by major taxing authorities since inception. Recent Accounting Pronouncements 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.

There were Level 1 assets include investments in money market funds that invest solely in U.S. government securities and investments in U.S. Treasury Securities. The Company uses inputs such as actual trade data, quoted market prices from dealers or brokers, and other similar sources to determine the fair value of its investments. The fair value of Public Warrants issued in connection with the Initial Public Offering are measured based on the listed market price of such warrants, a quoted price in an active market, a Level 1 measurement. The fair value of the Private Placement Warrants has been estimated using a Monte Carlo simulation model each measurement date. For the three months and nine months ended September 30, 2021, the Company recognized a gain resulting from a decrease in the fair value of the derivative warrant liabilities of approximately $1.1 For the three and nine months ended September 30, 2020, the Company recognized a loss of approximately $2.3 million and approximately $5.2 The estimated fair value of the Private Placement Warrants is determined using Level 3 inputs. Inherent in a Monte Carlo simulation are assumptions related to expected stock-price volatility, expected life, risk-free interest rate and dividend yield. The Company estimates the volatility of its common stock based on historical volatility of select peer companies that matches the expected remaining life of the warrants. The risk-free interest rate is based on the U.S. Treasury zero-coupon yield curve on the grant date for a 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 remaining at zero.

There no between Level 1 instruments include investments in money market funds and U.S. Treasury securities. The Company uses inputs such as actual trade data, benchmark yields, quoted market prices from dealers or brokers, and other similar sources to determine the fair value of its investments. The fair value of the Public Warrants issued in connection with the Public Offering and Private Placement Warrants were initially measured at fair value using a Monte Carlo simulation model and subsequently, the fair value of the Private Placement Warrants have been estimated using a Monte Carlo simulation model each measurement date. The fair value of Public Warrants issued in connection with the Initial Public Offering have been measured based on the listed market price of such warrants, a Level 1 measurement, beginning in June 2020. The estimated fair value of the Private Placement Warrants, and the Public Warrants prior to being separately listed and traded, is determined using Level 3 inputs. Inherent in a Monte Carlo simulation are assumptions related to expected stock-price volatility, expected life, risk-free interest rate and dividend yield. The Company estimates the volatility of its Class A common stock warrants based on implied volatility from the Company’s traded warrants and from historical volatility of select peer company’s Class A common stock that matches the expected remaining life of the warrants. The risk-free interest rate is based on the U.S. Treasury zero-coupon yield curve on the grant date for a 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 remaining at zero. There were no assets or liabilities measured at fair value on a recurring basis as of December 31, 2019.

Income Taxes
Income Taxes	Note 11 — Income Taxes The Company’s taxable income primarily consists of interest income on the Trust Account, less any franchise taxes. The Company’s formation and operating costs are generally considered start-up costs and are not currently deductible. The income tax provision (benefit) for the year ended December 31, 2020 consists of the following: December 31, 2020 December 31, 2019 Current Federal $ 11,434 $ — State — — Deferred Federal (101,676) (483) State — — Valuation allowance 101,676 483 Income tax provision 11,434 — The provision for income taxes was deemed to be de minimis for the period from November 1, 2019 (inception) through December 31, 2019. The Company’s net deferred tax assets are as follows: December 31, 2020 December 31, 2019 Deferred tax assets: Start-up/Organization costs $ 101,676 $ 315 Net operating loss carryforwards — 168 Total deferred tax assets 101,676 483 Valuation allowance (101,676) (483) Deferred tax asset, net of allowance $ — $ — In assessing the realization of deferred tax assets, management considers whether it is more likely than not that some portion or all of the deferred tax assets will not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which temporary differences representing net future deductible amounts become deductible. Management considers the scheduled reversal of deferred tax assets, projected future taxable income and tax planning strategies in making this assessment. After consideration of all of the information available, management believes that significant uncertainty exists with respect to future realization of the deferred tax assets and has therefore established a full valuation allowance. For the year ended December 31, 2020 and for the period from November 1, 2019 (inception) to December 31, 2019, the valuation allowance was $101,676 $483 A reconciliation of the statutory federal income tax rate (benefit) to the Company’s effective tax rate is as follows: December 31, 2020 December 31, 2019 Statutory federal income tax $ (1,748,979) $ (483) Change in fair value of derivative warrant liabilities (1,450,150) — Financing costs - derivative warrant liabilities (2,503) — Change in valuation allowance 3,213,066 483 Income tax expense $ 11,434 $ — There were no unrecognized tax benefits as of December 31, 2020, and 2019. No amounts were accrued for the payment of interest and penalties as of December 31, 2020, and 2019. 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. The Company’s management does not expect that the total amount of unrecognized tax benefits will materially change over the next twelve months.

Summary of Significant Accounting Policies (Policies)	9 Months Ended	12 Months Ended
Summary of Significant Accounting Policies (Policies)	Sep. 30, 2021	Dec. 31, 2020
Summary of Significant Accounting Policies
Basis of Presentation		Basis of presentation The Company’s financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”) for financial information and pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). The Company has no subsidiaries. As described in Note 2—Restatement of Previously Issued Financial Statements, the Company’s financial statements for the period as of December 31, 2020, and the year ended December 31, 2020, as of September 30, 2020 and for the three and nine months ended September 30, 2020, as of June 30, 2020 and for the three and six months ended June 30, 2020, and as of March 31, 2020 and for the three months ended March 31, 2020 (collectively, the “2020 Affected Periods”), are restated in this Annual Report on Form 10-K/A (Amendment No. 2) (this “Annual Report”) to correct the misapplication of accounting guidance related to the redeemable Class A common stock and earnings per share in the Company’s previously issued audited and unaudited condensed financial statements for such periods. The restated financial statements are indicated as “Restated” in the audited and unaudited condensed financial statements and accompanying notes, as applicable. See Note 2—Restatement of Previously Issued Financial Statements for further discussion.
Use of Estimates	Use of Estimates The preparation of unaudited condensed consolidated financial statements in conformity with GAAP requires the Company’s 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 unaudited condensed consolidated financial statements and the reported amounts of revenue and expenses during the reporting period. Making estimates requires management to exercise significant judgment. It is at least reasonably possible that the estimate of the effect of a condition, situation or set of circumstances that existed at the date of the unaudited condensed consolidated financial statements, which management considered in formulating its estimate, could change in the near term due to one or more future confirming events. One of the more significant accounting estimates included in these unaudited condensed financial statements is the determination of the fair value of the derivative warrant liabilities. Accordingly, the actual results could differ significantly from those estimates.

Accordingly, the actual results could differ from those estimates.
Cash and Cash Equivalents	Cash and Cash Equivalents The Company considers all short-term investments with an original maturity of three months or less when purchased to be cash equivalents. The Company had no cash equivalents as of September 30, 2021 and December 31, 2020.	Cash and Cash Equivalents The Company considers all short-term investments with an original maturity of three months or less when purchased to be cash equivalents. The Company had no cash equivalents as of December 31, 2020, and 2019.
Investments Held in the Trust Account	Investments Held in Trust Account The Company’s portfolio of investments is comprised of 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 investments in money market funds that invest in U.S. government securities and generally have a readily determinable fair value, or a combination thereof. When the Company’s investments held in the Trust Account are comprised of U.S. government securities, the investments are classified as trading securities. When the Company’s investments held in the Trust Account are comprised of money market funds, the investments are recognized at fair value. Trading securities and investments in money market funds are presented on the balance sheets at fair value at the end of each reporting period. Gains and losses resulting from the change in fair value of these securities is included in interest income on investments held in the Trust Account in the accompanying unaudited condensed consolidated statements of operations. The estimated fair values of investments held in the Trust Account are determined using available market information.	Investments Held in the Trust Account The Company’s portfolio of investments held in the Trust Account is comprised of 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 investments in money market funds that invest in U.S. government securities, or a combination thereof. The Company’s investments held in the Trust Account are classified as trading securities. Trading securities are presented on the balance sheet at fair value at the end of each reporting period. Gains and losses resulting from the change in fair value of these securities is included in net gain on investments, dividends and interest held in Trust Account in the accompanying statement of operations. The estimated fair values of investments held in the Trust Account were determined using available market information.
Fair Value of Financial Instruments	Fair Value of Financial Instruments The fair value of the Company’s assets and liabilities which qualify as financial instruments under the FASB ASC Topic 820, “Fair Value Measurements,” equal or approximate the carrying amounts represented in the condensed consolidated balance sheets.	Fair Value of Financial Instruments Fair value is defined as the price that would be received for sale of an asset, or paid for transfer of a liability, in an orderly transaction between market participants at the measurement date. U.S. GAAP establishes a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). These tiers include: ● Level 1, defined as observable inputs such as quoted prices (unadjusted) for identical instruments in active markets; ● Level 2, defined as inputs other than quoted prices in active markets that are either directly or indirectly observable such as quoted prices for similar instruments in active markets or quoted prices for identical or similar instruments in markets that are not active; and ● Level 3, defined as unobservable inputs in which little or no market data exists, therefore requiring an entity to develop its own assumptions, such as valuations derived from valuation techniques in which one or more significant inputs or significant value drivers are unobservable. In some circumstances, the inputs used to measure fair value might be categorized within different levels of the fair value hierarchy. In those instances, the fair value measurement is categorized in its entirety in the fair value hierarchy based on the lowest level input that is significant to the fair value measurement. As of December 31, 2020, and 2019, the carrying values of cash, prepaid expenses, accounts payable, accrued expenses, accrued expenses - related party, and tax obligations approximate their fair values due to the short-term nature of the instruments. The Company’s portfolio of marketable securities held in the Trust Account is comprised mainly of investments in U.S. Treasury securities with an original maturity of 185 days or less. The fair value for trading securities is determined using quoted market prices in active markets.
Offering Costs	Offering Costs Associated with the Initial Public Offering Offering costs consisted of legal, accounting, underwriting fees and other costs incurred through the Initial Public Offering that were directly related to the Initial Public Offering. Offering costs were allocated to the separable financial instruments issued in the Initial Public Offering based on a relative fair value basis, compared to total proceeds received. Offering costs associated with derivative warrant liabilities were expensed as incurred and presented as non-operating expenses in the condensed statements of operations. Offering costs associated with the Class A common stock issued were charged against the carrying value of the shares of Class A common stock upon the completion of the Initial Public Offering. The Company classifies deferred underwriting commissions as non-current liabilities as their liquidation is not reasonably expected to require the use of current assets or require the creation of current liabilities.	Offering Costs The Company complied with the requirements of the ASC 340-10-S99-1. Offering costs consist of legal, accounting, underwriting fees and other costs incurred that were directly attributable to the Initial Public Offering.. Offering costs are allocated to the separable financial instruments issued in the Initial Public Offering based on a relative fair value basis, compared to total proceeds received. Offering costs associated with warrant liabilities are expensed as incurred, presented as non-operating expenses in the statement of operations. Offering costs associated with the Public Shares were charged to the carrying value of the Class A common stock subject to possible redemption upon the completion of the Initial Public Offering. The Company classifies deferred underwriting commissions as their liquidation is not reasonably expected to require the use of current assets or require the creation of current liabilities.
Derivative Warrant Liabilities	Derivative Warrant Liabilities The Company does not use derivative instruments to hedge exposures to cash flow, market, or foreign currency risks. The Company evaluates all of its financial instruments, including issued stock purchase warrants, to determine if such instruments are derivatives or contain features that qualify as embedded derivatives, pursuant to ASC 480 and FASB ASC Topic 815, “Derivatives and Hedging” (“ASC 815”). The classification of derivative instruments, including whether such instruments should be recorded as liabilities or as equity, is re-assessed at the end of each reporting period. The 5,750,000 Public Warrants and the 3,733,334 Private Placement Warrants are recognized as derivative liabilities in accordance with ASC 815. Accordingly, the Company recognizes the warrant instruments as liabilities at fair value and adjusts the instruments to fair value at each reporting period. The liabilities are subject to re-measurement at each balance sheet date until exercised, and any change in fair value is recognized in the Company’s unaudited condensed consolidated statements of operations. The fair value of the Public Warrants issued in connection with the Public Offering and Private Placement Warrants were initially measured at fair value using a Monte Carlo simulation model and subsequently, the fair value of the Private Placement Warrants have been estimated using a Monte Carlo simulation model each measurement date. The fair value of Public Warrants issued in connection with the Initial Public Offering have subsequently been measured based on the listed market price of such warrants.	Derivative Warrant Liabilities The Company does not use derivative instruments to hedge its exposures to cash flow, market or foreign currency risks. Management evaluates all of the Company’s financial instruments, including issued warrants to purchase its Class A common stock, to determine if such instruments are derivatives or contain features that qualify as embedded derivatives, pursuant to ASC 480 and ASC 815-15. The classification of derivative instruments, including whether such instruments should be recorded as liabilities or as equity, is re-assessed at the end of each reporting period. The Company issued 5,750,000 warrants to purchase Class A common stock to investors in the Company’s Initial Public Offering, including the over-allotment, and simultaneously issued 3,733,334 Private Placement Warrants. All of the Company’s outstanding warrants are recognized as derivative liabilities in accordance with ASC 815-40. Accordingly, we recognize the warrant instruments as liabilities at fair value and adjust the instruments to fair value at each reporting period. The liabilities are subject to re-measurement at each balance sheet date until exercised, and any change in fair value is recognized in our statement of operations. The fair value of the Public Warrants issued in connection with the Public Offering and Private Placement Warrants were initially measured at fair value using a Monte Carlo simulation model and subsequently, the fair value of the Private Placement Warrants have been estimated using a Monte Carlo simulation model each measurement date. The fair value of Public Warrants issued in connection with the Initial Public Offering have subsequently been measured based on the listed market price of such warrants.
Class A Common Stock Subject to Possible Redemption	Class A Common Stock Subject to Possible Redemption The Company accounts for its Class A common stock subject to possible redemption in accordance with the guidance in ASC Topic 480 “Distinguishing Liabilities from Equity.” Shares of Class A common stock subject to mandatory redemption (if any) are classified as liability instruments and are measured at fair value. Shares of conditionally redeemable Class A common stock (including Class A common stock that feature redemption rights that are either within the control of the holder or subject to redemption upon the occurrence of uncertain events not solely within the Company’s control) are classified as temporary equity. At all other times, shares of Class A common stock are classified as stockholders’ equity. The Company’s Class A common stock feature certain redemption rights that are considered to be outside of the Company’s control and subject to the occurrence of uncertain future events. Accordingly, as of September 30, 2021, and December 31, 2020, 23,000,000 shares of Class A common stock subject to possible redemption are presented as temporary equity, outside of the stockholders’ equity section of the Company’s condensed consolidated balance sheets. Under ASC 480-10-S99, the Company has elected to recognize changes in the redemption value immediately as they occur and adjust the carrying value of the security to equal the redemption value at the end of each reporting period. This method would view the end of the reporting period as if it were also the redemption date for the security. Effective with the closing of the Initial Public Offering, the Company recognized the accretion from initial book value to redemption amount, which resulted in charges against additional paid-in capital (to the extent available) and accumulated deficit.	Class A Common Stock Subject to Possible Redemption (Restated - See Note 2) The Company accounts for its Class A common stock subject to possible redemption in accordance with the guidance in ASC Topic 480 “Distinguishing Liabilities from Equity.” Class A common stock subject to mandatory redemption (if any) is classified as liability instruments and are measured at fair value. Conditionally redeemable Class A common stock (including Class A common stock that features redemption rights that are either within the control of the holder or subject to redemption upon the occurrence of uncertain events not solely within the Company’s control) are classified as temporary equity. At all other times, Class A common stock is classified as stockholders’ equity. The Company’s Class A common stock feature certain redemption rights that are considered to be outside of the Company’s control and subject to the occurrence of uncertain future events. Accordingly, as of December 31, 2020, 23,000,000 shares of Class A common stock subject to possible redemption are presented as temporary equity, outside of the stockholders’ equity section of the Company’s balance sheets. Under ASC 480-10-S99, the Company has elected to recognize changes in the redemption value immediately as they occur and adjust the carrying value of the security to equal the redemption value at the end of each reporting period.

Accordingly, effective with the closing of the Initial Public Offering, the Company recognized the accretion from the initial book value to redemption amount, which resulted in charges against paid-in -capital (to the extent available) and accumulated deficit The Class A common stock subject to possible redemption reflected on the balance sheet is reconciled on the following table: Gross proceeds $ 230,000,000 Less: Amount allocated to Public Warrants (6,727,500) Class A common stock issuance costs (10,110,406) Plus: Accretion of carrying value to redemption value 16,837,906 Class A common stock subject to possible redemption $ 230,000,000
Net Income (Loss) Per Share of Common Stock	Net Income (Loss) Per Share of Common Stock The Company complies with accounting and disclosure requirements of FASB ASC Topic 260, “Earnings Per Share.” The Company has two classes of shares, which are referred to as Class A common stock and Class B common stock. Income and losses are shared pro rata between the two classes of shares. Net income (loss) per share of common stock is calculated by dividing the net income (loss) by the weighted average shares of common stock outstanding for the respective period. The calculation of diluted net income (loss) per share of common stock does not consider the effect of the warrants issued in connection with the Initial Public Offering and the Private Placement to purchase an aggregate of 9,483,334 shares of common stock in the calculation of diluted income (loss) per share, because their exercise is contingent upon future events and their inclusion would be anti-dilutive under the treasury stock method. As a result, diluted net income (loss) per share is the same as basic net income (loss) per share of common stock for the three and nine months ended September 30, 2021 and 2020. Accretion associated with the redeemable Class A common stock is excluded from earnings per share as the redemption value approximates fair value.

Income Taxes	Income Taxes The Company complies with the accounting and reporting requirements of Financial Accounting Standards Board Accounting Standard Codification, or ASC, 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. There were no unrecognized tax benefits as of September 30, 2021, and as of December 31, 2020. ASC 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 as income tax expense. No amounts were accrued for the payment of interest and penalties as of September 30, 2021, and December 31, 2020. The Company is currently not aware of any issues under review that could result in significant payments, accruals or material deviation from its position. The Company is subject to income tax examinations by major taxing authorities since inception.
