1. Description of Organization, Business Operations, and Basis of Presentation and Going Concern

FirstMark Horizon Acquisition Corp. (the “Company”) is a blank check company incorporated in Delaware on August 13, 2020. The Company was formed for the purpose of effecting a merger, capital stock exchange, asset acquisition, stock purchase, reorganization or similar business combination with one or more businesses (the “Business Combination”). The Company is an emerging growth company and, as such, the Company is subject to all of the risks associated with emerging growth companies.

As of JuneSeptember 30, 2021, the Company had not commenced any operations. All activity for the period from August 13, 2020 (inception) through JuneSeptember 30, 2021 relates to the Company’s formation and the initial public offering (the “Initial Public Offering”), described below, and since the closing of the Initial Public Offering, the search for a prospective initial 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 and securities from the proceeds derived from the Initial Public Offering (as defined below).

The Company’s sponsor is FirstMark Horizon Sponsor LLC, a Delaware limited liability company (the “Sponsor”). The registration statementstatements for the Company’s Initial Public Offering became effective on October 5, 2020. On October 8, 2020, the Company consummated its Initial Public Offering of 41,400,000 units (the “Units” and, with respect to the Class A common stock included in the Units sold, the “Public Shares”), including 5,400,000 additional Units to cover over-allotments (the “Over-Allotment Units”), at $10.00 per Unit, generating gross proceeds of $414.0 million, and incurring offering costs of approximately $23.3 million, inclusive of approximately $14.5 million in deferred underwriting commissions (Note 5).

Simultaneously with the closing of the Initial Public Offering, the Company consummated the private placement (“Private Placement”) of 6,853,333 warrants (each, a “Private Placement Warrant” and collectively, the “Private Placement Warrants”) at a price of $1.50 per Private Placement Warrant to the Sponsor, generating proceeds of approximately $10.3 million (Note 4).

Upon the closing of the Initial Public Offering and the Private Placement, $414.0 million ($10.00 per Unit) of the net proceeds of the Initial Public Offering and certain of the proceeds of the Private Placement was held in a trust account (“Trust Account”) located in the United States with Continental Stock Transfer & Trust Company acting as trustee, and invested only in U.S. “government securities,” within the meaning of Section 2(a)(16) of the Investment Company Act of 1940, as amended (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, which invest only in direct U.S. government treasury obligations, as determined by the Company, until the earlier of: (i) the completion of a Business Combination and (ii) the distribution of the Trust Account as described below.

The Company’s management has broad discretion with respect to the specific application of the net proceeds of the Initial Public Offering and the sale of Private Placement Warrants, although substantially all of the net proceeds are intended to be applied generally toward consummating a Business Combination. There is no assurance that the Company will be able to complete a Business Combination successfully. The Company must complete one or more initial Business Combinations having an aggregate fair market value of at least 80% of the net assets held in the Trust Account (as defined below) (excluding the amount of any deferred underwriting discount held in the Trust Account) at the time of the agreement to enter into the initial Business Combination. However, the Company only intends to complete a Business Combination if the post-transaction company owns or acquires 50% or more of the issued and outstanding voting securities of the target or otherwise acquires a controlling interest in the target sufficient for it not to be required to register as an investment company under the Investment Company Act 1940, as amended (the “Investment Company Act”).Act.

NOTES TO UNAUDITED CONDENSED FINANCIAL STATEMENTS

The Company will provide the holders (the “Public Stockholders”) of the Company’s issued and outstanding shares of Class A common stock, par value $0.0001 per share, sold in the Initial Public Offering (the “Public Shares”) with the opportunity to redeem all or a portion of their Public Shares upon the completion of a Business Combination either (i) in connection with a stockholder meeting called to approve the Business Combination or (ii) by means of a tender offer. The decision as to whether the Company will seek stockholder approval of a Business Combination or conduct a tender offer will be made by the Company, solely in its discretion. The Public Stockholders will be entitled to redeem their Public Shares for a pro rata portion of the amount then held in the Trust Account (initially anticipated to be $10.00 per Public Share). The per-share amount to be distributed to Public Stockholders who redeem their Public Shares will not be reduced by the deferred underwriting commissions the Company will pay to the underwriters (as discussed in Note 5). These Public Shares will be recorded at a redemption value and classified as temporary equity upon the completion of the Initial Public Offering in accordance with the Financial Accounting Standards Board’s (“FASB”) Accounting Standards Codification (“ASC”) Topic 480 “Distinguishing Liabilities from Equity” (“ASC 480”). If the Company seeks stockholder approval, the Company will proceed with a Business Combination if a majority of the shares voted are voted in favor of the Business Combination. The Company will not redeem the Public Shares in connection with a Business Combination in an amount that would cause its net tangible assets to be less than $5,000,001. If a stockholder vote is not required by law and the Company does not decide to hold a stockholder vote for business or other legal reasons, the Company will, pursuant to its Amended and Restated Certificate of Incorporation (the “Certificate of Incorporation”), conduct the redemptions pursuant to the tender offer rules of the U.S. Securities and Exchange Commission (“SEC”(the “SEC”) and file tender offer documents with the SEC prior to completing a Business Combination. If, however, stockholder approval of the transaction is required by law, or the Company decides to obtain stockholder approval for business or legal reasons, the Company will offer to redeem the Public Shares in conjunction with a proxy solicitation pursuant to the proxy rules and not pursuant to the tender offer rules. Additionally, each Public Stockholder may elect to redeem their Public Shares irrespective of whether they vote for or against the proposed transaction. If the Company seeks stockholder approval in connection with a Business Combination, the initial stockholders (as defined below) have agreed to vote their Founder Shares (as defined below in Note 4) and any Public Shares purchased during or after the Initial Public Offering in favor of a Business Combination. In addition, the initial stockholders have agreed to waive their redemption rights with respect to their Founder Shares and Public Shares in connection with the completion of a Business Combination.

The Certificate of Incorporation provides that a Public Stockholder, together with any affiliate of such stockholder or any other person with whom such stockholder is acting in concert or as a “group” (as defined under Section 13 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”)), will be restricted from redeeming its shares with respect to more than an aggregate of 15% of the Public Shares, without the prior consent of the Company.

The holders of the Founder Shares (the “initial stockholders”) have agreed not to propose an amendment to the Certificate of Incorporation (A) to modify the substance or timing of the Company’s obligation to allow redemption in connection with a Business Combination or to redeem 100% of the Public Shares if the Company does not complete a Business Combination within the Combination Period (as defined below) or (B) with respect to any other provision relating to stockholders’ rights or pre-initial Business Combination activity, unless the Company provides the Public Stockholders with the opportunity to redeem their Public Shares in conjunction with any such amendment.

If the Company is unable to complete a Business Combination within 24 months from the closing of the Initial Public Offering, or October 8, 2022, (the “Combination Period”) and the Company’s stockholders have not amended the Amended and Restated Certificate of Incorporation to extend such Combination Period, the Company will (1) cease all operations except for the purpose of winding up; (2) as promptly as reasonably possible but not more than 10 business days thereafter, redeem the Public Shares, at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account, including interest (less up to $100,000 of interest to pay dissolution expenses and which interest shall be net of taxes payable), divided by the number of then issued and outstanding Public Shares, which redemption will completely extinguish Public Stockholders’ rights as stockholders (including the right to receive further liquidating distributions, if any); and (3) as promptly as reasonably possible following such redemption, subject to the approval of the remaining stockholders and the Company’s board of directors, liquidate and dissolve, subject in each case to the Company’s obligations under Delaware law to provide for claims of creditors and the requirements of other applicable law.

FIRSTMARK HORIZON ACQUISITION CORP.

NOTES TO UNAUDITED CONDENSED FINANCIAL STATEMENTS

The initial stockholders have agreed to waive their rights to liquidating distributions from the Trust Account with respect to the Founder Shares if the Company fails to complete a Business Combination within the Combination Period. However, if the initial stockholders acquire Public Shares in or after the Initial Public Offering, they will be entitled to liquidating distributions from the Trust Account with respect to such Public Shares if the Company fails to complete a Business Combination within the Combination Period. The underwriters have agreed to waive their rights to the deferred underwriting commission (see Note 5) held in the Trust Account in the event the Company does not complete a Business Combination within the Combination Period and, in such event, such amounts will be included with the other funds held in the Trust Account that will be available to fund the redemption of the Public Shares. In the event of such distribution, it is possible that the per share value of the residual assets remaining available for distribution (including Trust Account assets) will be only $10.00. In order to protect the amounts held in the Trust Account, the Sponsor has agreed to be liable to the Company if and to the extent any claims by a third party (except for the Company’s independent registered public accounting firm) for services rendered or products sold to the Company, or a prospective target business with which the Company has discussed entering into a transaction agreement (a “Target”), reduce the amount of funds in the Trust Account to below (i) $10.00 per Public Share or (ii) the lesser amount per Public Share held in the Trust Account as of the date of the liquidation of the Trust Account due to reductions in the value of the trust assets, in each case net of interest which may be withdrawn to pay taxes, provided that such liability will not apply to any claims by a third party or Target that executed a waiver of any and all rights to seek access to the Trust Account nor will it apply to any claims under the Company’s indemnity of the underwriters of the Initial Public Offering against certain liabilities, including liabilities under the Securities Act of 1933, as amended (the “Securities Act”). In the event that an executed waiver is deemed to be unenforceable against a third party, our sponsor will not be responsible to the extent of any liability for such third-party claims. The Company will seek to reduce the possibility that the Sponsor will have to indemnify the Trust Account due to claims of creditors by endeavoring to have all vendors, service providers (other than the Company’s independent registered public accounting firm), prospective target businesses or other entities with which the Company does business, execute agreements with the Company waiving any right, title, interest or claim of any kind in or to monies held in the Trust Account.

Proposed Business Combination

On October 6, 2021, the Company entered into an Agreement and Plan of Merger (the “Merger Agreement”) with Sirius Merger Sub, Inc., a Delaware corporation and a wholly owned direct subsidiary of the Company (“Merger Sub”), Starry, Inc., a Delaware corporation (“Starry”), and Starry Holdings, Inc., a Delaware corporation and wholly owned direct subsidiary of Starry (“Holdings”). Pursuant to the Merger Agreement, and subject to the terms and conditions contained therein, the business combination will be effected in two steps: (a) the Company will merge with and into Holdings (the “SPAC Merger” and, the closing of the SPAC Merger, the “SPAC Merger Closing,” and, the time at which the SPAC Merger becomes effective, the “SPAC Merger Effective Time”), with Holdings surviving the SPAC Merger as a publicly traded entity (such surviving entity, “New Starry”), and becoming the sole owner of Merger Sub; and (b) at least twenty-four (24) hours, but no more than forty-eight (48) hours, after the SPAC Merger Effective Time, Merger Sub will merge with and into Starry (the “Acquisition Merger” and, together with the SPAC Merger and all other transactions contemplated by the Merger Agreement, the “Business Combination”), with Starry surviving the Acquisition Merger as a wholly owned subsidiary of New Starry. New Starry will have a dual-class share structure with super voting rights for Starry’s co-founder and Chief Executive Officer, Chaitanya Kanojia.

NOTES TO UNAUDITED CONDENSED FINANCIAL STATEMENTS

Restatement to 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 the SEC and its staff’s guidance on redeemable equity instruments in ASC 480-10-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. 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 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 Form 8-K filed with the SEC on October 14, 2020 (the “Post-IPO Balance Sheet”), the Form 10-K/A filed with the SEC on May 27, 2021 and the Company’s Form 10-Qs 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 Post-IPO Balance Sheet, the Form 10-K/A and 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 previously presented Post-IPO Balance Sheet, Form 10-K/A and Affected Quarterly Periods should no longer be relied upon.

The impact of the restatement to the Post-IPO Balance Sheet is an increase to Class A common stock subject to possible redemption of approximately $52.1 million, a decrease to additional paid-in capital of $6.3 million, an increase to the accumulated deficit of $45.7 million, and the reclassification of 5,206,820 Class A common stock from permanent equity to Class A common stock subject to possible redemption as presented below.

The impact of the restatement on the financial statements for the Form 10-K/A is presented below.

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.

Risks and Uncertainties

Management continues to evaluate the impact of the COVID-19 pandemic on the 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 unaudited condensed financial statements. The unaudited condensed financial statements do not include any adjustments that might result from the outcome of this uncertainty.

Liquidity and Going Concern

As of JuneSeptember 30, 2021, the Company had approximately $464,000$270,000 in its operating bank account, approximately $13,000$19,000 of interest income available in the Trust Account to pay the Company’s franchise and income tax obligations and a working capital deficit of approximately $140,000.$3.0 million. Further, the Company has incurred and expectexpects to continue to incur significant costs in pursuit of its acquisition plans.

The Company’s liquidity needs to date have been satisfied through the $25,000 proceeds received from the sale of its Founder Shares (as defined below) to the Sponsor, the loan proceeds under a promissory note of $167,000 from the Sponsor to cover the Company’s offering costs in connection with the Initial Public Offering, and the net proceeds from the consummation of the Private Placement not held in the Trust Account. The balance of the promissory note was fully repaid on October 8, 2020. 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 Working Capital Loans (see Note 4). As of JuneSeptember 30, 2021 and December 31, 2020, there were no amounts outstanding under any Working Capital Loans.

Based on the foregoing, management has determined that the working capital deficit raises substantial doubt about the Company’s ability to continue as a going concern until the earlier of the consummation of a Business Combination or the date the Company is required to liquidate. The unaudited condensed financial statements do not include any adjustment that might be necessary if the Company is unable to continue as a going concern. Over this time period, the Company will be using these funds for paying existing accounts payable, identifying and evaluating prospective initial Business Combination candidates, performing due diligence on prospective target businesses, paying for travel expenditures, selecting the target business to merge with or acquire, and structuring, negotiating and consummating the Business Combination.

2. Significant Accounting Policies.Policies

Use of Estimates

The preparation of unaudited condensed 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 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 financial statements, which management considered in formulating its estimate, could change in the near term due to one or more future confirming events. Accordingly, the actual results could differ significantly from those estimates.

Cash and Cash Equivalents

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

Concentration of Credit Risk

Financial instruments that potentially subject the Company to concentration of credit risk consist of cash accounts in a financial institution which, at times, may exceed the Federal depository insuranceDeposit Insurance Corporation coverage limit of $250,000, and investments held in Trust Account. TheAs of September 30, 2021 and December 31, 2020, the Company has not experienced losses on these accounts and management believes the Company is not exposed to significant risks on such accounts.

NOTES TO UNAUDITED CONDENSED FINANCIAL STATEMENTS

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 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 income from investments held in Trust Account in the accompanying unaudited condensed statements of operations. The estimated fair values of investments held in the Trust Account are determined using available market information.

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 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. 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:consist of:

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.

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, 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.

FIRSTMARK HORIZON ACQUISITION CORP.

NOTES TO UNAUDITED CONDENSED FINANCIAL STATEMENTS

The 13,800,000 warrants issued in connection with the Initial Public Offering (the “Public Warrants”) and the 6,853,333 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 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 the Company’s statement of operations. The initial and subsequent fair value of the Private Warrants and the initial fair value of the Public Warrants issued in connection with the private placement and initial public offering, respectively, have been measured using a binomial lattice model in an option pricing framework. The fair value of the Public Warrants has subsequently been determined using listed prices in an active market for such warrants. The determination of the fair value of the warrant liability may be subject to change as more current information becomes available and accordingly the actual results could differ significantly. Derivative warrant liabilities are classified 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.

FIRSTMARK HORIZON ACQUISITION CORP.

NOTES TO UNAUDITED CONDENSED FINANCIAL STATEMENTS

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 derivative warrant liabilities are expensed as incurred, presented as non-operating expenses in the statement of operations. Offering costs associated with the Class A common stock issued were charged to stockholders’ equityagainst the carrying value of the 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 FASB 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 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, as of June 30, 2021 and December 31, 2020,the Initial Public Offering, a total of 36,278,872 and 34,438,23041,400,000 shares of Class A common stock subject to possible redemption, respectively, are presented at redemption value as temporary equity, outside of the stockholders’ equity section of the Company’s balance sheet.

Effective with the closing of the Initial Public Offering and the over-allotment option, 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.

Reconciliation of Net Income (Loss) per Share of Common Stock

The Company’s net income (loss) is adjusted for the portion of income (loss) that is attributable to redeemable common stock, as these shares only participate in the earnings of the Trust Account and not the income or losses of the Company. Accordingly, basic and diluted income (loss) per share of common stock is calculated as follows:

Income Taxes

The Company follows the asset and liability method of accounting for income taxes under FASB ASC Topic 740, “Income Taxes” (“ASC 740”). Deferred tax assets and liabilities are recognized for the estimated future tax consequences attributable to differences between the financial statements 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. As of JuneSeptember 30, 2021 and December 31, 2020, the Company has aggregate deferred tax assets of approximately $298,000$819,000 and $267,000, respectively, and has recognized a full valuation allowance against the deferred tax assets.

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. There were no unrecognized tax benefits as of JuneSeptember 30, 2021 and December 31, 2020. The Company recognizes accrued interest and penalties related to unrecognized tax benefits as income tax expense. The Company’s currently taxable income primarily consists of interest and dividends earned and unrealized gains on investments held in the Trust Account. The Company’s general and administrative costs are generally considered start-up costs and are not currently deductible.

No amounts were accrued for the payment of interest and penalties as of JuneSeptember 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 Adopted Accounting Standards

In August 2020, the FASB issued ASU No. 2020-06, Debt—DebtDebt-Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging—ContractsHedging-Contracts in Entity’s Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity, 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 also simplifies the diluted earnings per share calculation in certain areas. The Company early adopted the ASU on January 1, 2021.2021 using a modified retrospective method of transition. Adoption of the ASU did not impact the Company’s financial position, results of operations or cash flows.

Management does not believe that any other recently issued, but not yet effective, accounting standards if currently adopted would have a material effect on the accompanying financial statements.

On October 8, 2020, the Company consummated its Initial Public Offering of 41,400,000 Units, including 5,400,000 Over-Allotment Units, at $10.00 per Unit, generating gross proceeds of $414.0 million, and incurring offering costs of approximately $23.3 million, inclusive of approximately $14.5 million in deferred underwriting commissions.

Each Unit consists of one share of Class A common stock, and one-third of one redeemable warrant (each, a “Public Warrant”). Each Public Warrant entitles the holder to purchase one share of Class A common stock at a price of $11.50 per share, subject to adjustment (see Note 6).

The Company transferred an aggregate of 120,000 Founder Shares to certain members of the Company’s management team. On October 5, 2020, the Company effected a 1:1.2 stock split of its Class B common stock, resulting in the Sponsor holding an aggregate of 10,230,000 Founder Shares and there being an aggregate of 10,350,000 Founder Shares outstanding. All shares and associated amounts have been retroactively restated to reflect the stock split. The Sponsor agreed to forfeit up to 1,350,000 Founder Shares to the extent that the over-allotment option is not exercised in full by the underwriters, so that the Founder Shares would represent 20.0% of the Company’s issued and outstanding shares after the Initial Public Offering. The underwriter exercised its over-allotment option in full on October 6, 2020; thus, the 1,350,000 Founder Shares were no longer subject to forfeiture.

The initial stockholders agreed, subject to limited exceptions, not to transfer, assign or sell any of the Founder Shares until the earlier to occur of: (A) one year after the completion of the initial Business Combination; and (B) subsequent to the initial Business Combination (x) if the last reported sale price of Class A common stock equals or exceeds $12.00 per share (as adjusted for stock splits, stock dividends, reorganizations, recapitalizations and the like) for any 20 trading days within any 30-trading day period commencing at least 150 days after the initial Business Combination or (y) the date on which the Company completes a liquidation, merger, stock exchange, reorganization or other similar transaction that results in all of the Public Stockholders having the right to exchange their shares of Class A common stock for cash, securities or other property.

Private Placement Warrants

Simultaneously with the closing of the Initial Public Offering, the Company consummated the Private Placement of 6,853,333 Private Placement Warrants, at a price of $1.50 per Private Placement Warrant to the Sponsor, generating proceeds of approximately $10.3 million.

Each Private Placement Warrant is exercisable for one whole share of Class A common stock at a price of $11.50 per share. A portion of the proceeds from the sale of the Private Placement Warrants to the Sponsor were added to the net proceeds from the Initial Public Offering held in the Trust Account. If the Company does not complete a Business Combination within the Combination Period, the Private Placement Warrants will expire worthless. The Private Placement Warrants will be non-redeemable (except as described below in Note 6 under “Warrants —- Redemption of warrants when the price per share of Class A common stock equals or exceeds $10.00”) so long as they are held by the initial purchasers or their permitted transferees.

The purchasers of the Private Placement Warrants agreed, subject to limited exceptions, not to transfer, assign or sell any of their Private Placement Warrants (except to permitted transferees) until 30 days after the completion of the initial Business Combination.

Related Party Loans

On August 18, 2020, the Sponsor agreed to loan the Company an aggregate of up to $300,000 to cover expenses related to the Initial Public Offering pursuant to a promissory note (the “Note”). This loan was non-interest bearing and payable upon the completion of the Initial Public Offering. The Company borrowed $167,000 under the Note. The Company repaid the Note in full on October 8, 2020.

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, loan the Company funds as may be required (“Working Capital Loans”). If the Company completes a Business Combination, the Company will repay the Working Capital Loans out of the proceeds of the Trust Account released to the Company. Otherwise, the Working Capital Loans would be repaid only out of funds held outside the Trust Account. In the event that a Business Combination does not close, the Company may use a portion of proceeds held outside the Trust Account to repay the Working Capital Loans but no proceeds held in the Trust Account would be used to repay the Working Capital Loans. The Working Capital Loans would either be repaid upon consummation of a Business Combination or, at the lender’s discretion, up to $1.5 million of such Working Capital Loans may be convertible into warrants of the post Business Combination entity at a price of $1.50 per warrant. The warrants would be identical to the Private Placement Warrants. Except for the foregoing, the terms of such Working Capital Loans, if any, have not been determined and no written agreements exist with respect to such loans. To date, the Company had no borrowings under the Working Capital Loans.

8.9. Fair Value Measurements.

The following table presents information about the Company’s assets and liabilities that are measured at fair value on a recurring basis and indicate the fair value hierarchy of the valuation techniques that the Company utilized to determine such fair value.

Transfers to/from Levels 1, 2, and 3 are recognized at the beginning of the reporting period. The estimated fair value of the Public Warrants transferred from a Level 3 measurement to a Level 1 fair value measurement in December 2020, upon trading of the Public Warrants in an active market. The estimated fair value of the Private Warrants was transferred from a Level 3 measurement to a Level 2 fair value measurement as of September 30, 2021, as the transfer of Private Placement Warrants to anyone who is not a permitted transferee would result in the Private Placement Warrants having substantially the same terms as the Public Warrants, the Company determined that the fair value of each Private Placement Warrant is equivalent to that of each Public Warrant.

Level 1 assets include investments money market funds that invest solely in U.S. government 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 initial and subsequent fair value of the Private Warrants and the initial fair value of the Public Warrants issued in connection with the private placement and initial public offering, respectively, have been measured using a binomial lattice model in an option pricing framework. The fair value of the Public Warrants has subsequently been determined using listed prices in an active market for such warrants. For the three and nine months ended JuneSeptember 30, 2021, the Company recognized a benefit to the unaudited condensed statement of operations resulting from a decrease in the fair value of liabilities of approximately $19.4$5.6 million and $25.4 million, respectively, which is presented as a change in fair value of derivative warrant liabilities on the accompanying unaudited condensed statement of operations.

FIRSTMARK HORIZON ACQUISITION CORP.

NOTES TO UNAUDITED CONDENSED FINANCIAL STATEMENTS

The initial 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 binomial lattice model in an option pricing framework are assumptions related to expected stock-price volatility, the probability of a successful business combination, term, risk-free interest rate and dividend yield. For the initial fair value estimates, the Company estimates volatility based on the constituents of a broad-based stock price index reflecting the potential merger targets and including a probability of a successful business combination. For subsequent fair value measurements, the Company estimates the volatility of its common stock based on the implied volatility derived from the traded prices of the Public Warrants which includes a probability of successful business combination. The probability of a successful business combination as of the initial measurement date is based on industry studies and the Company’s best estimates. The risk-free interest rate is based on the term-matched U.S. Treasury yield curve as of the measurement dates. The term of the warrants is equal to their remaining contractual term. The dividend rate is based on the historical rate, which the Company anticipates remaining at zero.

The following table provides quantitative information regarding Level 3 fair value measurements inputs as their measurement dates:at December 31, 2020:

The change in the fair value of the warrant liabilities, measured using Level 3 inputs, for the three months and sixnine months ended JuneSeptember 30, 2021 is summarized as follows:

Overview

We are a blank check company incorporated in Delaware on August 13, 2020 for the purpose of effecting a merger, capital stock exchange, asset acquisition, stock purchase, reorganization or similar business combination with one or more businesses (the “Business Combination”). Our sponsor is FirstMark Horizon Sponsor LLC, a Delaware limited liability company (the “Sponsor”).

The registration statements for our initial public offering (“Initial Public Offering”) became effective on October 5, 2020. On October 8, 2020, we consummated the Initial Public Offering of 41,400,000 units (the “Units” and, with respect to the Class A common stock included in the Units being offered, the “Public Shares”), including 5,400,000 Units to cover over-allotments (the “Over-Allotment Units”), at $10.00 per Unit, generating gross proceeds of $414.0 million, and incurring offering costs of approximately $23.3 million, inclusive of approximately $14.5 million in deferred underwriting commissions.

Simultaneously with the closing of the Initial Public Offering, we consummated the private placement (“Private Placement”) of 6,853,333 warrants (each, a “Private Placement Warrant” and collectively, the “Private Placement Warrants”) at a price of $1.50 per Private Placement Warrant to our Sponsor, generating proceeds of approximately $10.3 million.

Upon the closing of the Initial Public Offering and the Private Placement, $414.0 million ($10.00 per Unit) of the net proceeds of the Initial Public Offering and certain of the proceeds of the Private Placement was held in a trust account (“Trust Account”) located in the United States with Continental Stock Transfer & Trust Company acting as trustee, and invested only in U.S. “government securities,” within the meaning of Section 2(a)(16) of the Investment Company Act of 1940, as amended (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, which invest only in direct U.S. government treasury obligations, as determined by the Company, until the earlier of: (i) the completion of a Business Combination and (ii) the distribution of the Trust Account as described below.

If we are unable to complete a Business Combination within 24 months from the closing of the Initial Public Offering, or October 8, 2022, (the “Combination Period”) and our stockholders have not amended the Amended and Restated Certificate of Incorporation to extend such Combination Period, we will (1) cease all operations except for the purpose of winding up; (2) as promptly as reasonably possible but not more than 10 business days thereafter, redeem the Public Shares, at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account, including interest (less up to $100,000 of interest to pay dissolution expenses and which interest shall be net of taxes payable), divided by the number of then issued and outstanding Public Shares, which redemption will completely extinguish Public Stockholders’ rights as stockholders (including the right to receive further liquidating distributions, if any); and (3) as promptly as reasonably possible following such redemption, subject to the approval of the remaining stockholders and our board of directors, liquidate and dissolve, subject in each case to our obligations under Delaware law to provide for claims of creditors and the requirements of other applicable law.

Proposed Business Combination

On October 6, 2021, the Company entered into an Agreement and Plan of Merger (the “Merger Agreement”) with Sirius Merger Sub, Inc., a Delaware corporation and a wholly owned direct subsidiary of the Company (“Merger Sub”), Starry, Inc., a Delaware corporation (“Starry”), and Starry Holdings, Inc., a Delaware corporation and wholly owned direct subsidiary of Starry (“Holdings”). Pursuant to the Merger Agreement, and subject to the terms and conditions contained therein, the business combination will be effected in two steps: (a) the Company will merge with and into Holdings (the “SPAC Merger” and, the closing of the SPAC Merger, the “SPAC Merger Closing,” and, the time at which the SPAC Merger becomes effective, the “SPAC Merger Effective Time”), with Holdings surviving the SPAC Merger as a publicly traded entity (such surviving entity, “New Starry”) and becoming the sole owner of Merger Sub; and (b) at least twenty-four (24) hours, but no more than forty-eight (48) hours, after the SPAC Merger Effective Time, Merger Sub will merge with and into Starry (the “Acquisition Merger” and, together with the SPAC Merger and all other transactions contemplated by the Merger Agreement, the “Business Combination”), with Starry surviving the Acquisition Merger as a wholly owned subsidiary of New Starry. New Starry will have a dual-class share structure with super voting rights for Starry’s co-founder and Chief Executive Officer, Chaitanya Kanojia.

Refer to the Current Report on Form 8-K, filed with the Securities and Exchange Commission on October 7, 2021 for additional information.

Liquidity and Capital ResourcesGoing Concern

As of JuneSeptember 30, 2021, we had approximately $464,000$270,000 in our operating bank account, approximately $13,000$19,000 of interest income available in the Trust Account to pay the Company’s franchise and income tax obligations and a working capital deficit of approximately $140,000.$3.0 million. Further, we have incurred and expect to continue to incur significant costs in pursuit of its acquisition plans.

Our liquidity needs to date have been satisfied through the $25,000 capital contribution to purchase founder shares by our Sponsor, the loan proceeds under a promissory note of $167,000 from our Sponsor to cover the Company’s offering costs in connection with the Initial Public Offering, and the net proceeds from the consummation of the Private Placement not held in the Trust Account. The balance of the promissory note was fully repaid on October 8, 2020. In addition, in order to finance transaction costs in connection with a Business Combination, our Sponsor or an affiliate of our Sponsor, or certain of our officers and directors may, but are not obligated to, provide us Working Capital Loans. As of JuneSeptember 30, 2021 and December 31, 2020, there were no amounts outstanding under any Working Capital Loans.

Based on the foregoing, we have determined that the working capital deficit raises substantial doubt about our ability to continue as a going concern until the earlier of the consummation of a Business Combination or the date we are required to liquidate. The unaudited condensed financial statements do not include any adjustment that might be necessary if we are unable to continue as a going concern. Over this time period, we will be using these funds for paying existing accounts payable, identifying and evaluating prospective initial Business Combination candidates, performing due diligence on prospective target businesses, paying for travel expenditures, selecting the target business to merge with or acquire, and structuring, negotiating and consummating the Business Combination.

Results of Operations

Our entire activity since inception through JuneSeptember 30, 2021 related to our formation, the preparation for the Initial Public Offering, and since the closing of the Initial Public Offering, the search for a prospective initial Business Combination. We have neither engaged in any operations nor generated any revenues to date. We will not generate any operating revenues until after completion of our initial Business Combination. We generate non-operating income in the form of interest income and dividends on investments held in Trust Account. We expect to incur increased expenses as a result of being a public company (for legal, financial reporting, accounting and auditing compliance), as well as for due diligence expenses and transaction related expenses.

For the three months ended JuneSeptember 30, 2021, we had net lossincome of approximately $323,000,$3.1 million, which consisted of a non-operating gain resulting from the change in fair value of derivative warrant liabilities of approximately $413,000$5.6 million and interest and dividends on investments held in the Trust Account of approximately $7,000,$6,000, partially offset by approximately $743,000$2.5 million of operating expenses. Total operating expenses for the three months ended JuneSeptember 30, 2021 were comprised of approximately $693,000$2.4 million of general and administrative costs, including $30,000 of administrative services expenses to related parties, and approximately $50,000 of franchise tax expense.

For the sixnine months ended JuneSeptember 30, 2021, we had net income of approximately $18.4$21.5 million, which consisted of a non-operating gain resulting from the change in fair value of derivative warrant liabilities of approximately $19.8$25.4 million and interest and dividends on investments held in the Trust Account of approximately $13,000,$19,000, partially offset by approximately $1.4$3.9 million of operating expenses. Total operating expenses for the sixnine months ended JuneSeptember 30, 2021 were comprised of approximately $1.3$3.7 million of general and administrative costs, including $60,000$90,000 of administrative services expenses to related parties, and approximately $98,000$148,000 of franchise tax expense.

Related Party Transactions

Founder Shares

OnFor the period from August 18,13, 2020 our Sponsor purchased 8,625,000 shares of the Company’s Class B common stock, par value $0.0001 per share, (the “Founder Shares”) for an aggregate price of $25,000. The Company transferred an aggregate of 120,000 Founder Shares to certain members of our management team. On October 5,(inception) through September 30, 2020, the Company effectedwe had a 1:1.2 stock split of its Class B common stock, resulting in our Sponsor holding an aggregate of 10,230,000 Founder Shares and there being an aggregate of 10,350,000 Founder Shares outstanding. All shares and associated amounts have been retroactively restated to reflect the stock split. Our Sponsor agreed to forfeit up to 1,350,000 Founder Shares to the extent that the over-allotment option is not exercised in full by the underwriters, so that the Founder Shares would represent 20.0% of the Company’s issued and outstanding shares after the Initial Public Offering. The underwriter exercised its over-allotment option in full on October 6, 2020; thus, the 1,350,000 Founder Shares were no longer subject to forfeiture.

The initial stockholders agreed, subject to limited exceptions, not to transfer, assign or sell any of the Founder Shares until the earlier to occur of: (A) one year after the completion of the initial Business Combination; and (B) subsequent to the initial Business Combination (x) if the last reported sale price of Class A common stock equals or exceeds $12.00 per share (as adjusted for stock splits, stock dividends, reorganizations, recapitalizations and the like) for any 20 trading days within any 30-trading day period commencing at least 150 days after the initial Business Combination or (y) the date on which we complete a liquidation, merger, stock exchange, reorganization or other similar transaction that results in all of the Public Stockholders having the right to exchange their shares of Class A common stock for cash, securities or other property. Any permitted transferees will be subject to the same restrictions and other agreements of the initial stockholders with respect to any Founder Shares.

Private Placement Warrants

Simultaneously with the closing of the Initial Public Offering, we consummated the Private Placement of 6,853,333 Private Placement Warrants, at a price of $1.50 per Private Placement Warrant to the Sponsor, generating proceedsnet loss of approximately $10.3 million.

Each Private Placement Warrant is exercisable for one whole share$30,000, which consisted of Class A common stock at a price of $11.50 per share. A portion of the proceeds from the sale of the Private Placement Warrants to the Sponsor were added to the net proceeds from the Initial Public Offering held in the Trust Account. If the Company does not complete a Business Combination within the Combination Period, the Private Placement Warrants will expire worthless. The Private Placement Warrants will be non-redeemable (except as described below in Note 6 under “Warrants — Redemption of warrants when the price per share of Class A common stock equals or exceeds $10.00”) so long as they are held by the initial purchasers or their permitted transferees.

The purchasers of the Private Placement Warrants agreed, subject to limited exceptions, not to transfer, assign or sell any of their Private Placement Warrants (except to permitted transferees) until 30 days after the completion of the initial Business Combination.

Related Party Loans

On August 18, 2020, our Sponsor agreed to loan us an aggregate of up to $300,000 to cover expenses related to the Initial Public Offering pursuant to a promissory note (the “Note”). This loan was non-interest bearing and payable upon the completion of the Initial Public Offering. The Company fully borrowed $167,000 under the Note. We repaid the Note in full on October 8, 2020.

In addition, in order to finance transaction costs in connection with a Business Combination, our Sponsor or an affiliate of our Sponsor, or certain of our officers and directors may, but are not obligated to, loan us funds as may be required (“Working Capital Loans”). If we complete a Business Combination, we will repay the Working Capital Loans out of the proceeds of the Trust Account released to the Company. Otherwise, the Working Capital Loans would be repaid only out of funds held outside the Trust Account. In the event that a Business Combination does not close, we may use a portion of proceeds held outside the Trust Account to repay the Working Capital Loans but no proceeds held in the Trust Account would be used to repay the Working Capital Loans. The Working Capital Loans would either be repaid upon consummation of a Business Combination or, at the lender’s discretion, up to $1.5 million of such Working Capital Loans may be convertible into warrants of the post Business Combination entity at a price of $1.50 per warrant. The warrants would be identical to the Private Placement Warrants. Except for the foregoing, the terms of such Working Capital Loans, if any, have not been determined and no written agreements exist with respect to such loans. To date, we have no borrowings under the Working Capital Loans.

Administrative Services Agreement

We entered into an agreement that provides that, commencing on October 6, 2020, through the earlier of consummation of the initial Business Combination and the Company’s liquidation, we will pay an affiliate of the Sponsor a total of $10,000 per month for office space, administrative and support services. For the three and six months ended June 30, 2021, we incurredoperating expenses of $30,000approximately $4,000 and $60,000, under this agreement, respectively. There were no balances outstanding under such agreement asapproximately $26,000 of June 30, 2021 and December 31, 2020.

Our Sponsor, officers and directors, or any of their respective affiliates, will be reimbursed for any out-of-pocket expenses incurred in connection with activities on the Company’s behalf such as identifying potential target businesses and performing due diligence on suitable Business Combinations. Our audit committee will review on a quarterly basis all payments that were made by us to our Sponsor, directors, officers or the Company’s or any of their affiliates.franchise tax expense.

Contractual Obligations

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 we 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 us. We will bear the expenses incurred in connection with the filing of any such registration statements.

Underwriting Agreement

The underwriter was entitled to an underwriting discount of $0.20 per share, or approximately $8.28 million in the aggregate, paid upon the closing of the Initial Public Offering. In addition, $0.35 per share, or approximately $14.5 million in the aggregate will be payable to the underwriter for deferred underwriting commissions. The deferred fee will become payable to the underwriter from the amounts held in the Trust Account solely in the event that we complete a Business Combination, subject to the terms of the underwriting agreement.

Administrative Services Agreement

We entered into an agreement that provides that, commencing on October 6, 2020, through the earlier of consummation of the initial Business Combination and the Company’s liquidation, we will pay an affiliate of the Sponsor a total of $10,000 per month for office space, administrative and support services. For the three and nine months ended September 30, 2021, we incurred expenses of $30,000 and $90,000, under this agreement, respectively. There were no balances outstanding under such agreement as of September 30, 2021 and December 31, 2020.

Our Sponsor, officers and directors, or any of their respective affiliates, will be reimbursed for any out-of-pocket expenses incurred in connection with activities on the Company’s behalf such as identifying potential target businesses and performing due diligence on suitable Business Combinations. Our audit committee will review on a quarterly basis all payments that were made by us to our Sponsor, directors, officers or the Company’s or any of their affiliates.

Critical Accounting Policies and Estimates

Derivative Warrant liabilities

We do not use derivative instruments to hedge exposures to cash flow, market, or foreign currency risks. We evaluate all of our financial instruments, including issued stock purchase warrants, to determine if such instruments are derivatives or contain features that qualify as embedded derivatives, pursuant to Financial Accounting Standards Board’s (“FASB”) Accounting Standards Codification (“ASC”) Topic 480 “Distinguishing Liabilities from Equity” (“ASC 480”) and ASC 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 13,800,000 warrants issued in connection with the Initial Public Offering (the “Public Warrants”) and the 6,853,333 Private Placement Warrants are recognized as derivative liabilities in accordance with ASC 815. 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 the Company’s statement of operations. The initial and subsequent fair value of the Private Warrants and the initial fair value of the Public Warrants issued in connection with the private placement and initial public offering, respectively, have been measured using a binomial lattice model in an option pricing framework. The fair value of the Public Warrants has subsequently been determined using listed prices in an active market for such warrants. The determination of the fair value of the warrant liability may be subject to change as more current information becomes available and accordingly the actual results could differ significantly. Derivative warrant liabilities are classified 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

We account for our Class A common stock subject to possible redemption in accordance with the guidance in FASB ASC 480.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’sour control) are classified as temporary equity. At all other times, shares of Class A common stock are classified as stockholders’ equity. Our Class A common stock features certain redemption rights that are considered to be outside of our control and subject to the occurrence of uncertain future events. Accordingly, as of June 30, 2021 and December 31, 2020,the Initial Public Offering, a total of 36,278,872 and 34,438,23041,400,000 shares of Class A common stock subject to possible redemption, respectively, are presented at redemption value as temporary equity, outside of the stockholders’ equity section of our balance sheet.

Effective with the closing of the Initial Public Offering and the over-allotment option, we 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)(loss) Per Share of Common Stock

We applyThe 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-class method in calculating earnings per share.two classes of shares. Net income (loss) per common share is computedcalculated by dividing the net income (loss) by the weighted-average number ofweighted average shares of common stock outstanding duringfor the respective period.

Accretion associated with the redeemable Class A common stock is excluded from earnings per share as the redemption value approximates fair value.

Recent Adopted Accounting Standards

In August 2020, the FASB issued ASU No. 2020-06, Debt—DebtDebt-Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging—ContractsHedging-Contracts in Entity’s Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity, 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 also simplifies the diluted earnings per share calculation in certain areas. We early adopted the ASU on January 1, 2021. Adoption of the ASU did not impact our financial position, results of operations or cash flows.

Recent Issued Accounting Standards

Our 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 financial statement.

Off-Balance Sheet Arrangements

As of JuneSeptember 30, 2021, we did not have any off-balance sheet arrangements as defined in Item 303(a)(4)(ii) of Regulation S-K.

Inflation

We do not believe that inflation had a material impact on our business, revenues or operating results during the period presented.

JOBS Act

The Jumpstart Our Business Startups Act of 2012 (the “JOBS Act”) contains provisions that, among other things, relax certain reporting requirements for qualifying public companies. We qualify as an “emerging growth company” and under the JOBS Act are allowed to comply with new or revised accounting pronouncements based on the effective date for private (not publicly traded) companies. We are electing to delay the adoption of new or revised accounting standards, and as a result, we may not comply with new or revised accounting standards on the relevant dates on which adoption of such standards is required for non-emerging growth companies. As a result, the financial statements may not be comparable to companies that comply with new or revised accounting pronouncements as of public company effective dates.

Additionally, we are in the process of evaluating the benefits of relying on the other reduced reporting requirements provided by the JOBS Act. Subject to certain conditions set forth in the JOBS Act, if, as an “emerging growth company,” we choose to rely on such exemptions we may not be required to, among other things, (i) provide an auditor’s attestation report on our system of internal controls over financial reporting pursuant to Section 404, (ii) provide all of the compensation disclosure that may be required of non-emerging growth public companies under the Dodd-Frank Wall Street Reform and Consumer Protection Act, (iii) comply with any requirement that may be adopted by the Public Company Accounting Oversight Board regarding mandatory audit firm rotation or a supplement to the auditor’s report providing additional information about the audit and the financial statements (auditor discussion and analysis) and (iv) disclose certain executive compensation related items such as the correlation between executive compensation and performance and comparisons of the CEO’s compensation to median employee compensation. These exemptions will apply for a period of five years following the completion of our Initial Public Offering or until we are no longer an “emerging growth company,” whichever is earlier.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

As of June 30, 2021, we were not subject to any market or interest rate risk. The net proceedsWe are a smaller reporting company as defined by Rule 12b-2 of the Initial Public Offering, including amounts inExchange Act and are not required to provide the Trust Account, will be invested in U.S. government securities within the meaning of Section 2(a)(16) of the Investment Company Act having a maturity of 180 days or less or in money market funds meeting certain conditionsinformation otherwise required under Rule 2a-7 promulgated under the Investment Company Act which invest only in direct U.S. government treasury obligations. Due to the short-term nature of these investments, we believe there will be no associated material exposure to interest rate risk.this item.

We have not engaged in any hedging activities since our inception, and we do not expect to engage in any hedging activities with respect to the market risk to which we are exposed.

ITEM 4. CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

Under the supervision and with the participation of our management, including our principal executive officer and principal financial officer, we conducted an evaluation of the effectiveness of our disclosure controls and procedures as of the end of the fiscal quarter ended JuneSeptember 30, 2021, as such term is defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act. Based on this evaluation, our principal executive officer and principal financial officer has concluded that during the period covered by this report, our disclosure controls and procedures were not effective as of JuneSeptember 30, 2021, due solely to thebecause of a material weakness in our internal control over financial reporting. A material weakness is a deficiency, or a combination of deficiencies, in internal control over financial reporting, described in Note 2 — Restatement of Previously Issued Financial Statements, included in Part II, Item 8such that there is a reasonable possibility that a material misstatement of the Form 10-K/A filed with the SEC on May 27, 2021. In light of this material weakness, we performed additional analysis as deemed necessary to ensure that our unauditedCompany’s annual or interim financial statements were preparedwill not be prevented or detected on a timely basis. Specifically, the Company’s management has concluded that our control around the interpretation and accounting for certain complex features of the Class A common stock and warrants issued by the Company was not effectively designed or maintained. This material weakness resulted in accordance with U.S. generally accepted accounting principles. Accordingly, management believes that the unaudited condensedrestatement of the Company’s balance sheet as of October 8, 2021, Form 10-K/A as of December 31, 2020 and its interim financial statements included in this Quarterly Report on Form 10Q present fairly in all material respects our financial position, results of operations and cash flows for the period presented.quarters ended March 31, 2021 and June 30, 2021.

Disclosure controls and procedures are designed to ensure that information required to be disclosed by us in our Exchange Act reports is recorded, processed, summarized, and reported within the time periods specified in the SEC’s rules and forms, and that such information is accumulated and communicated to our management, including our principal executive officer and principal financial officer or persons performing similar functions, as appropriate to allow timely decisions regarding required disclosure.

Changes in Internal Control over Financial Reporting

There was no change in our internal control over financial reporting that occurred during the fiscal quarter ended JuneSeptember 30, 2021, covered by this Quarterly Report on Form 10-Q that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting asexcept for the errors identified in Note 2 — Restatement of Previously Issuedbelow:

The Chief Executive Officer and Chief Financial Statements, included in Part II, Item 8Officer performed additional accounting and financial analyses and other post-closing procedures including consulting with subject matter experts related to the accounting for certain complex features of the Form 10-K/Class A filed withcommon stock and warrants. The Company’s management has expended, and will continue to expend, a substantial amount of effort and resources for the SEC on May 27, 2021 had not yet been identified. Management has implemented remediation steps to address the material weakness and to improveimprovement of our internal control over financial reporting. Specifically,While we have processes to properly identify and evaluate the appropriate accounting technical pronouncements and other literature for all significant or unusual transactions, we have expanded and improved our review process for complex securities and related accounting standards. We planwill continue to further improve this process by enhancing accessthese processes to accounting literature, identificationensure that the nuances of third-party professionals with whom to consult regardingsuch transactions are effectively evaluated in the context of the increasingly complex accounting applications and consideration of additional staff with the requisite experience and training to supplement existing accounting professionals.standards.

ITEM 1A. RISK FACTORS.

Factors that could cause our actual results to differ materially from those in this Quarterly Report are any of the risks described in our FY 2020 10-K/A. Any of these factors could result in a significant or material adverse effect on our results of operations or financial condition. Additional risk factors not presently known to us or that we currently deem immaterial may also impair our business or results of operations. As of the date of this Quarterly Report, other than as described below, there have been no material changes to the risk factors disclosed in our FY 2020 10-K/A, except we may disclose changes to such factors or disclose additional factors from time to time in our future filings with the SEC.

We identified a material weakness in our internal control over financial reporting as of September 30, 2021. If we are unable to develop and maintain an effective system of internal control over financial reporting, we may not be able to accurately report our financial results in a timely manner, which may adversely affect investor confidence in us and materially and adversely affect our business and operating results.

After consultation with our independent registered public accounting firm, our management and our audit committee concluded that we identified a material weakness in our internal controls over financial reporting.

A material weakness is a deficiency, or a combination of deficiencies, in internal control over financial reporting such that there is a reasonable possibility that a material misstatement of our annual or interim financial statements will not be prevented, or detected and corrected on a timely basis.

Effective internal controls are necessary for us to provide reliable financial reports and prevent fraud. We continue to evaluate steps to remediate the material weakness. These remediation measures may be time consuming and costly and there is no assurance that these initiatives will ultimately have the intended effects.

If we identify any new material weaknesses in the future, any such newly identified material weakness could limit our ability to prevent or detect a misstatement of our accounts or disclosures that could result in a material misstatement of our annual or interim financial statements. In such case, we may be unable to maintain compliance with securities law requirements regarding timely filing of periodic reports in addition to applicable stock exchange listing requirements, investors may lose confidence in our financial reporting and our stock price may decline as a result. We cannot assure you that the measures we have taken to date, or any measures we may take in the future, will be sufficient to avoid potential future material weaknesses.
