Summary of Significant Accounting Policies | Note 2—Basic of Presentation and Summary of Significant Accounting Policies ​ Basis of Presentation ​ The accompanying unaudited consolidated condensed financial statements of the Company, including the accounts of the Company’s wholly-owned subsidiary, STPK Merger Sub Corp, have been prepared in accordance with United States generally accepted accounting principles (“U.S. GAAP”) for interim financial information and Article 8 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by U.S. GAAP. all adjustments (consisting of normal accruals) considered for a fair presentation have been included. All intercompany accounts and transactions have been eliminated in consolidation. In the opinion of management, operating results for the periods presented are not necessarily indicative of the results that may be expected for the year ending December 31, 2021, or any other future period. ​ The accompanying unaudited consolidated condensed financial statements should be read in conjunction with the audited financial statements and notes thereto included in the Company’s Annual Report on Form 10K/A filed with the SEC on April 26, 2021. Emerging Growth Company ​ The Company is an “emerging growth company,” as defined in Section 2(a) of the Securities Act, as modified by the Jumpstart Our Business Startups Act of 2012 (the “JOBS Act”), and it may take advantage of certain exemptions from various reporting requirements that are applicable to other public companies that are not emerging growth companies including, but not limited to, not being required to comply with the auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act of 2002, reduced disclosure obligations regarding executive compensation in its periodic reports and proxy statements, and exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and stockholder approval of any golden parachute payments not previously approved. Further, Section 102(b)(1) of the JOBS Act exempts emerging growth companies from being required to comply with new or revised financial accounting standards until private companies (that is, those that have not had a Securities Act registration statement declared effective or do not have a class of securities registered under the Exchange Act) are required to comply with the new or revised financial accounting standards. The JOBS Act provides that an emerging growth company can elect to opt out of the extended transition period and comply with the requirements that apply to non-emerging growth companies but any such an 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 unaudited consolidated condensed financial statements with another public company that is neither an emerging growth company nor an emerging growth company that has opted out of using the extended transition period difficult or impossible because of the potential differences in accounting standards used. Use of Estimates ​ The preparation of unaudited consolidated condensed financial statements in conformity with U.S. GAAP requires the Company’s management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosures of contingent assets and liabilities at the date of the unaudited consolidated condensed 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 unaudited consolidated condensed financial statements, which management considered in formulating its estimate, could change in the near term due to one or more future confirming events. Accordingly, the actual results could differ significantly from those estimates. Cash and Cash Equivalents The Company considers all short-term investments with an original maturity of three months or less when purchased to be cash equivalents. There were no cash equivalents at March 31, 2021 and December 31, 2020. Investments Held in Trust Account The Company’s portfolio of investments is comprised solely 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 consolidated condensed 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 gain on investment (net), dividends and interest held in Trust Account in the accompanying unaudited consolidated condensed statements of operations. The estimated fair values of investments held in the Trust Account are 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 Depository Insurance Coverage 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 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 March 31, 2021 and December 31, 2020, the carrying values of cash, accounts payable, accrued expenses, and franchise tax payable approximate their fair values due to the short-term nature of the instruments. The Company’s portfolio of investments held in the Trust Account is comprised of investments in U.S. Treasury securities with an original maturity of 185 days or less or investments in money market funds that invest in U.S. government securities, or a combination thereof. The fair value for trading securities is determined using quoted market prices in active markets. 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 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 statements of operations. Offering costs associated with the Class A common stock were charged to stockholders' equity upon the completion of the Initial Public Offering. 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.” Class A common stock subject to mandatory redemption (if any) is classified as a liability instrument and measured at fair value. Shares of 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 are classified as stockholders’ equity. The Company’s Class A common stock features certain redemption rights that are considered to be outside of the Company’s control and subject to the occurrence of uncertain future events. Accordingly, at March 31, 2021 and December 31, 2020, 8,640,832 and 24,275,528 shares of Class A common stock subject to possible redemption are presented as temporary equity, respectively, outside of the stockholders’ equity section of the Company’s consolidated condensed balance sheets. 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 tax assets and liabilities are recognized for the estimated future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that included the enactment date. Valuation allowances are established, when necessary, to reduce deferred tax assets to the amount expected to be realized. 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. Net Income (Loss) Per Share of Common Stock Net income (loss) per share of common stock is computed by dividing net income (loss) by the weighted-average number of common stock outstanding during the periods. The Company has not considered the effect of the warrants sold in the Initial Public Offering and the Private Placement to purchase up to an aggregate of 19,967,302 shares of the Company’s Class A common stock in the calculation of the diluted income per share, since their inclusion would be anti-dilutive under the treasury stock method. As a result, diluted earnings per share of common stock is the same as basic earnings per share of common stock for the periods presented. The Company’s unaudited consolidated condensed statements of operations include a presentation of income (loss) per share for common stock subject to redemption in a manner similar to the two-class method of income (loss) per share. Net income per share, basic and diluted for Class A common stock is calculated by dividing the gain on investment (net), dividends and interest held in Trust Account of approximately $35,000, net of applicable taxes available to be withdrawn from the Trust Account of approximately $35,000, by the weighted average number of Class A common stock outstanding for the three months ended March 31, 2021. Net loss per share, basic and diluted for Class B common stock is calculated by dividing the net loss of approximately $156.3 million and $0 for the three months ended March 31, 2021 and 2020, respectively, less income attributable to Class A common stock of $0 for each period, by the weighted average number of Class B common stock outstanding for the periods. 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 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 accounts for its 19,967,302 common stock warrants issued in connection with its Initial Public Offering (12,786,168) and Private Placement (7,181,134) as derivative warrant liabilities in accordance with ASC 815-40. 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 statements of operations. The fair value of the Private Placement Warrants have been estimated using a Monte Carlo simulation model each measurement date. The fair value of the warrants issued in connection with the Public Offering were initially measured at fair value using a Monte Carlo simulation model and subsequently measured based on the listed market price of such warrants. Recent Adopted Accounting Standards In August 2020, the FASB issued Accounting Standards 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 (“ASU 2020-06”), which simplifies accounting for convertible instruments by removing major separation models required under current GAAP. The ASU also removes certain settlement conditions that are required for equity-linked contracts to qualify for the derivative scope exception, and it simplifies the diluted earnings per share calculation in certain areas. The Company adopted ASU 2020-06 on January 1, 2021. Adoption of the ASU did not impact the Company’s financial position, results of operations or cash flows. Recent Issued Accounting Standards ​ The Company’s management does not believe that any recently issued, but not yet effective, accounting standards updates, if currently adopted, would have a material effect on the accompanying financial statement.
