Description of Organization, Business Operations, Basis of Presentation and Going Concern | 1. Description of Organization, Business Operations, 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 December 31, 2021, the Company had not commenced any operations. All activity for the period from August 13, 2020 (inception) through December 31, 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 statements 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. 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 (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 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. 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 Group Holdings, Inc. (formerly 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 “Starry 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 Company’s Current Report on Form 8-K, filed with the SEC on October 7, 2021 for additional information. Basis of Presentation The accompanying consolidated financial statements are presented in U.S. dollars, in conformity with accounting principles generally accepted in the United States of America (“GAAP”) for financial information and pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). Principles of Consolidation The consolidated financial statements of the Company include its wholly-owned subsidiary created in connection with the proposed Business Combination. All inter-company accounts and transactions are eliminated in consolidation. 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 consolidated 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. 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 consolidated financial statements. The consolidated financial statements do not include any adjustments that might result from the outcome of this uncertainty. Liquidity and Going Concern As of December 31, 2021, the Company had approximately $531,000 in its operating bank account, approximately $32,000 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 $2.6 million. Further, the Company has incurred and expects 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 December 31, 2021 and 2020, there were no amounts outstanding under any Working Capital Loans. Based on the foregoing, management has determined that the liquidity condition and mandatory liquidation, should a Business Combination not occur, and potential subsequent dissolution raises substantial doubt about the Company’s ability to continue as a going concern. The consolidated 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. |
