DESCRIPTION OF ORGANIZATION AND BUSINESS OPERATIONS | Big Rock Partners Acquisition Corp. (the “Company”) is a blank check company incorporated in Delaware on September 18, 2017. The Company was formed for the purpose of acquiring, through a merger, share exchange, asset acquisition, stock purchase, reorganization, recapitalization, or other similar business transaction, one or more operating businesses or entities (a “Business Combination”). The Company is not limited to a particular industry or geographic region for purposes of consummating a Business Combination. The Company has one subsidiary, Big Rock Merger Corp., a wholly-owned subsidiary of the Company incorporated in Delaware on January 22, 2019 (“Merger Sub”). All activity through December 31, 2020 relates to the Company’s formation, its initial public offering (“Initial Public Offering”), which is described below, identifying a target company for a Business Combination, and activities in connection with the proposed acquisition of NeuroRx, Inc., a Delaware corporation (“ NeuroRx The registration statement for the Company’s Initial Public Offering was declared effective on November 20, 2017. On November 22, 2017, the Company consummated the Initial Public Offering of 6,000,000 units (the “Units” and, with respect to the common stock included in the Units being offered, the “Public Shares”), generating gross proceeds of $60,000,000, which is described in Note 3. Each Unit consists of one share of common stock, one right (“Public Right”) and one-half of one warrant (“Public Warrant”). Each Public Right will convert into one-tenth (1/10) of one share of common stock upon consummation of a Business Combination. Each whole Public Warrant entitles the holder to purchase one share of common stock at an exercise price of $11.50 per whole share. Simultaneously with the Initial Public Offering, the Company consummated the sale of 250,000 units (the “Private Placement Units”) at a price of $10.00 per Unit in a private placement to Big Rock Partners Sponsor, LLC (the “Sponsor”), generating gross proceeds of $2,500,000, which is described in Note 4. Following the closing of the Initial Public Offering, $60,000,000 ($10.00 per Unit) from the net proceeds of the sale of the Units in the Initial Public Offering and the Private Placement Units was placed in a trust account (the “Trust Account”) which may be invested in U.S. government securities, within the meaning set forth in Section 2(a)(16) of the Investment Company Act of 1940, as amended (the “Investment Company Act”), with a maturity of 180 days or less or in any open-ended investment company that holds itself out as a money market fund selected by the Company meeting the conditions of Rule 2a-7 of the Investment Company Act, as determined by the Company, until the earlier of: (i) the consummation of a Business Combination or (ii) the distribution of the Trust Account, as described below. On November 29, 2017, in connection with the underwriters’ exercise of their over-allotment option in full, the Company consummated the sale of an additional 900,000 Units, and the sale of an additional 22,500 Private Placement Units at $10.00 per unit, generating total gross proceeds of $9,225,000. A total of $9,000,000 of the net proceeds were deposited in the Trust Account, bringing the aggregate proceeds held in the Trust Account to $69,000,000. At the closing of the Initial Public Offering, the Company issued EarlyBirdCapital, Inc. ("EarlyBirdCapital") and its designees 120,000 shares of common stock (the “Representative Shares”). On November 29, 2017, the Company issued an additional 18,000 Representative Shares for no consideration (see Note 8). Transaction costs amounted to $2,172,419, consisting of $1,725,000 of underwriting fees and $447,419 of Initial Public Offering costs. The Company’s management has broad discretion with respect to the specific application of the net proceeds of the Initial Public Offering and Private Placement Units, although substantially all of the net proceeds are intended to be applied generally toward consummating a Business Combination. The Company’s initial Business Combination must be with one or more target businesses that together have a fair market value equal to at least 80% of the balance in the Trust Account (excluding taxes payable on income earned on the Trust Account) at the time of the signing an agreement to enter into a Business Combination. The Company will only complete a Business Combination if the post-Business Combination company owns or acquires 50% or more of the outstanding voting securities of the target or otherwise acquires a controlling interest in the target sufficient for it not to be required to register as an investment company under the Investment Company Act. There is no assurance that the Company will be able to successfully effect a Business Combination. The Company will provide its stockholders with the opportunity to redeem all or a portion of their shares included in the Units sold in the Initial Public Offering (the “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 stockholders will be entitled to redeem their shares for a pro rata portion of the amount then on deposit in the Trust Account ($10.00 per share, plus any pro rata interest earned on the funds held in the Trust Account and not previously released to the Company to pay its franchise and income tax obligations). There will be no redemption rights upon the completion of a Business Combination with respect to the Company’s warrants. The Company will proceed with a Business Combination if the Company has net tangible assets of at least $5,000,001 upon such consummation of a Business Combination and, if the Company seeks stockholder approval, a majority of the outstanding shares voted are voted in favor of the Business Combination. 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, conduct the redemptions pursuant to the tender offer rules of the Securities and Exchange Commission (the “SEC”), and file tender offer documents with the SEC prior to completing a Business Combination. If, however, a stockholder approval of the transaction is required by law, or the Company decides to obtain stockholder approval for business or other legal reasons, the Company will offer to redeem shares in conjunction with a proxy solicitation pursuant to the proxy rules and not pursuant to the tender offer rules. If the Company seeks stockholder approval in connection with a Business Combination, the Company’s Sponsor, officers and directors (the “Initial Stockholders”) have agreed (a) to vote their Founder’s Shares (as defined in Note 5), Placement Shares (as defined in Note 4) and any Public Shares held by them in favor of approving a Business Combination and (b) not to convert any Founder’s Shares, Placement Shares and any Public Shares held by them in connection with a stockholder vote to approve a Business Combination or sell any such shares to the Company in a tender offer in connection with a Business Combination. Additionally, each public stockholder may elect to redeem their Public Shares irrespective of whether they vote for or against the proposed transaction. The Company initially had until November 22, 2018 to complete a Business Combination. However, if the Company anticipated that it would not be able to consummate a Business Combination by November 22, 2018, the Company could extend the period of time to consummate a Business Combination up to two times, each by an additional three months. Pursuant to the terms of the Company's Amended and Restated Certificate of Incorporation and the trust agreement entered into between the Company and Continental Stock Transfer & Trust Company on November 20, 2017, in order to extend the time available for the Company to consummate a Business Combination, the Sponsor or its affiliates or designees must deposit into the Trust Account $690,000 ($0.10 per share) for each three month extension, up to an aggregate of $1,380,000, or $0.20 per share, if the Company extends for the full six months, on or prior to the date of the applicable deadline. On November 20, 2018, the period of time for the Company to consummate a Business Combination was extended for an additional three-month period ending on February 22, 2019, and, accordingly, $690,000 was deposited into the Trust Account. On February 21, 2019, the Company further extended the time required to consummate a Business Combination to May 22, 2019 and deposited an additional $690,000 into the Trust Account. The deposits were funded by non-interest bearing unsecured promissory notes from BRAC Lending Group LLC, an affiliate of the underwriter (“BRAC”) (see Note 6). The notes are repayable upon the consummation of a Business Combination (see Note 6). On May 21, 2019, the Company’s stockholders approved an amendment to its Amended and Restated Certificate of Incorporation to extend the period of time for which the Company was required to consummate a Business Combination to August 22, 2019. The number of shares of common stock presented for redemption in connection with the extension was 2,119,772. The Company paid cash in the aggregate amount of $22,099,233, or approximately $10.43 per share, to redeeming stockholders. The Company agreed to deposit, or cause to be deposited on its behalf, into the Trust Account $0.02 for each public share outstanding for each 30-day extension period utilized through August 22, 2019. In connection with this extension, the Company deposited an aggregate of $286,814 into the Trust Account, of which $280,000 was contributed to the Trust Account by a third party and is not required to be repaid by the Company. Accordingly, the Company has recorded this amount as a credit to additional paid in capital in the accompanying statements of stockholders’ equity. In order to pay for part of the third extension payment, the Company issued an unsecured promissory note (the “Second Note”) in favor of BRAC, in the original principal amount of $6,814 (see Note 6). On August 21, 2019, the Company stockholders approved an amendment to the Company’s Amended and Restated Certificate of Incorporation to extend the period of time for which the Company is required to consummate a Business Combination (the “Extension”) from August 22, 2019 to November 22, 2019. The number of shares of common stock presented for redemption in connection with the Extension was 846,888. The Company paid cash in the aggregate amount of $8,891,378, or approximately $10.50 per share, to redeeming stockholders. The Company agreed to deposit, or cause to be deposited on its behalf, into the Trust Account $0.02 for each public share outstanding for each 30-day extension period utilized through the Extension. In connection with this extension, the Company deposited an aggregate of $236,000 into the Trust Account to fund this extension payment, which amount was loaned to the Company by AZ Property Partners, LLC (“AZ Property Partners”), an entity majority owned and controlled by Richard Ackerman, the Company's Chairman, President and Chief Executive Officer, and BRAC (see Note 6). On November 21, 2019, the Company's stockholders approved an amendment to the Company's Amended and Restated Certificate of Incorporation to extend the period of time for which the Company is required to consummate a Business Combination (the “Second Extension”) from November 22, 2019 to March 23, 2020. The number of shares of common stock presented for redemption in connection with the Second Extension was 919,091. The Company paid cash in the aggregate amount of $9,736,077, or approximately $10.59 per share, to redeeming stockholders. The Company agreed to deposit, or cause to be deposited on its behalf, into the Trust Account $0.02 for each public share outstanding for each 30-day extension period utilized through the Second Extension. In connection with this extension, the Company deposited an aggregate of $60,285 into the Trust Account to fund the first thirty-day extension through December 22, 2019, which amount was loaned to the Company by AZ Property Partners and BRAC (see Note 6). In January and February 2020, AZ Property Partners and BRAC loaned the Company an additional aggregate amount of $90,427 each to pay for the extension through March 23, 2020, which was deposited into the Trust Account. On March 23, 2020, the Company's stockholders approved an amendment to the Amended and Restated Certificate of Incorporation to extend the period of time for which the Company is required to consummate a Business Combination (the “Third Extension”) from March 23, 2020 to July 23, 2020. The number of shares of common stock presented for redemption in connection with the Third Extension was 2,433,721. The Company paid cash in the aggregate amount of $25,997,965, or approximately $10.68 per share, to redeeming stockholders. The Company agreed to deposit, or cause to be deposited on its behalf, into the Trust Account $0.02 for each public share outstanding for each 30-day extension period utilized through the Third Extension. Notwithstanding the foregoing, if the volume weighted average price of the Company's common stock during the 10-day trading period ending on the 3rd day prior to the end of any applicable monthly period was equal to or greater than $11.00 and the trading volume during the 10-day trading period exceeded 100,000 shares, the obligation to make any particular deposit would terminate with respect to the immediately following monthly period (but not with respect to any other future monthly period). In connection with this extension, the Company deposited an aggregate of $34,858 into the Trust Account to fund the extension through July 23, 2020, of which $17,429 was loaned to the Company by each of AZ Property Partners and BRAC. On July 23, 2020, the Company's stockholders approved an amendment to the Amended and Restated Certificate of Incorporation to extend the period of time for which the Company is required to consummate a Business Combination (the “Fourth Extension”) from July 23, 2020 to December 23, 2020. The number of shares of common stock presented for redemption in connection with the Fourth Extension was 27,786. The Company paid cash in amount of $299,253, or approximately $10.77 per share, to redeeming stockholders. The Company agreed to deposit, or cause to be deposited on its behalf, into the Trust Account $0.02 for each public share outstanding for each 30-day extension period utilized through the Fourth Extension. In connection with this extension, as of November 13, 2020, the Company deposited an aggregate of $44,219 into the Trust Account, of which $22,110 was deposited as of September 30, 2020, to fund the extension through November 23, 2020, which amounts were loaned to the Company by AZ Property Partners and BRAC. Notwithstanding the foregoing, if the volume weighted average price of the Company's common stock during the 10-day trading period ending on the 3rd day prior to the end of any applicable monthly period is equal to or greater than $11.00 and the trading volume during the 10-day trading period exceeds 100,000 shares, the obligation to make any particular deposit would terminate with respect to the immediately following monthly period (but not with respect to any other future monthly period). On December 18, 2020, the Company held a special meeting pursuant to which the Company’s stockholders approved an amendment to the Amended and Restated Certificate of Incorporation to extend the period of time for which the Company is required to consummate a Business Combination (the “Fifth Extension”) from December 23, 2020 to April 23, 2021 (the “Extended Date”). In connection with this extension, no stockholders elected to redeem their shares of common stock. If the Company is unable to complete a Business Combination by the Extended Date, the Company will (i) cease all operations except for the purpose of winding up, (ii) as promptly as reasonably possible but no more than ten business days thereafter, redeem 100% of the outstanding Public Shares, at a per share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account, including interest earned (net of taxes payable), divided by the number of then outstanding Public Shares, which redemption will completely extinguish public stockholders’ rights as stockholders (including the right to receive further liquidation distributions, if any), subject to applicable law, and (iii) as promptly as reasonably possible following such redemption, subject to the approval of the remaining stockholders and the Company’s board of directors, proceed to commence a voluntary liquidation and thereby a formal dissolution of the Company, subject in each case to its obligations to provide for claims of creditors and the requirements of applicable law. In the event of such distribution, it is possible that the per share value of the assets remaining available for distribution (including Trust Account assets) will be less than the $10.00 per Unit in the Initial Public Offering. The Initial Stockholders have agreed to (i) waive their redemption rights with respect to Founder Shares, Placement Shares and any Public Shares they may acquire during or after the Initial Public Offering in connection with the consummation of a Business Combination, (ii) to waive their rights to liquidating distributions from the Trust Account with respect to their Founder’s Shares and Placement Shares if the Company fails to consummate a Business Combination by the Extended Date and (iii) not to propose an amendment to the Company’s Amended and Restated Certificate of Incorporation that would affect the substance or timing of the Company’s obligation to redeem 100% of its Public Shares if the Company does not complete a Business Combination, unless the Company provides the public stockholders with the opportunity to redeem their Public Shares in conjunction with any such amendment. However, the Initial Stockholders will be entitled to liquidating distributions with respect to any Public Shares acquired if the Company fails to consummate a Business Combination or liquidates by Extended Date. In order to protect the amounts held in the Trust Account, A/Z Property Partners, has agreed that it will be liable to ensure that the proceeds in the Trust Account are not reduced below $10.00 per share by the claims of target businesses or claims of vendors or other entities that are owed money by the Company for services rendered or contracted for or products sold to the Company. Additionally, the agreement entered into by AZ Property Partners specifically provides for two exceptions to the indemnity it has given: it will have no liability (1) as to any claimed amounts owed to a target business or vendor or other entity who has executed an agreement with the Company waiving any right, title, interest or claim of any kind they may have in or to any monies held in the Trust Account, or (2) as to any claims for indemnification by the underwriters against certain liabilities, including liabilities under the Securities Act of 1933, as amended (the “Securities Act”). The Company will seek to reduce the possibility that AZ Property Partners will have to indemnify the Trust Account due to claims of creditors by endeavoring to have all vendors, service providers, prospective target businesses or other entities with which the Company does business, execute agreements with the Company waiving any right, title, interest or claim of any kind in or to monies held in the Trust Account. NASDAQ Notifications On January 7, 2019, the Company received a notice from the staff of the Listing Qualifications Department of Nasdaq (the “Staff”) stating that the Company was no longer in compliance with Nasdaq Listing Rule 5620(a) for continued listing due to its failure to hold an annual meeting of stockholders within twelve months of the end of the Company’s fiscal year ended December 31, 2017. The Company submitted a plan of compliance with Nasdaq and Nasdaq granted the Company an extension until May 22, 2019 to regain compliance with the rule by holding an annual meeting of stockholders. The Company held its annual meeting of stockholders on May 21, 2019 and, accordingly, the Staff determined that the Company was in compliance with Nasdaq Listing Rule 5620(a) for continued listing and the matter was closed. On August 9, 2019, the Company received a notice from the Staff stating that the Company was no longer in compliance with Nasdaq Listing Rule 5550(a)(3) for continued listing due to its failure to maintain a minimum of 300 public holders (the “Rule”). The Company had until September 23, 2019 to provide Nasdaq with a specific plan to achieve and sustain compliance with the listing requirement. The notice is a notification of deficiency, not of imminent delisting, and had no current effect on the listing or trading of the Company's securities on Nasdaq. On September 23, 2019 and October 28, 2019, the Company submitted a plan to regain compliance with Nasdaq and requested an extension through February 5, 2020. On October 28, 2019, Nasdaq requested additional information regarding the Company's compliance plan, to which the Company responded on November 8, 2019. On February 11, 2020, the Company received a notice from the Staff stating that, based upon the Company’s non-compliance with the Rule, the Staff had determined to delist the Company’s common stock from Nasdaq unless the Company timely requests a hearing before the Nasdaq Hearings Panel (the “Panel“). The Company was also notified that as a result of Nasdaq’s determination to delist the Company’s common stock, the Company’s warrants and rights no longer comply with Nasdaq Listing Rule 5560(a), which requires the underlying securities of such exercisable securities to remain listed on Nasdaq, and the Company’s Units no longer comply with Nasdaq Listing Rule 5225(b)(1)(A), which requires all component parts of units to meet the requirements for initial and continued listing, and the Company’s units, warrants and rights are now subject to delisting. The Company requested a hearing, which request automatically stayed any further action by the Staff pending the ultimate conclusion of the hearing process. On March 25, 2020, the Company received formal notice from Nasdaq indicating that the Staff had granted the Company’s request for continued listing on Nasdaq. The decision followed the Company’s hearing before the Panel, which took place on March 19, 2020. The Company’s continued listing is subject to the Company’s satisfaction of a number of conditions, including, ultimately, completion of a Business Combination with an operating company by no later than August 10, 2020, and the combined entity’s compliance with all applicable criteria for initial listing on Nasdaq at the time of the merger. The Company failed to meet certain of the conditions contained in the extension grant and has submitted a modified extension request to the Staff. On August 10, 2020, the Company submitted a letter to Nasdaq indicating that it was in compliance with the Rule as of July 31, 2020 and, as a result, satisfies the minimum 300 public holder requirement and all other applicable criteria for continued listing on Nasdaq. Accordingly, the Company requested that the Staff render a formal determination to continue the listing of the Company’s securities. On August 11, 2020, the Company received a formal notice from Nasdaq notifying the Company that it regained compliance with the minimum 300 public holder requirements under Nasdaq rules and that the Panel had determined to continue the listing of the Company's securities on Nasdaq and close the matter. On November 23, 2020, the Company received a notice from Nasdaq stating that, as of November 20, 2020, the Company was not in compliance with Listing Rule IM-5101-2 (the “Rule”), which requires that a special purpose acquisition company complete one or more business combinations within 36 months of the effectiveness of the registration statement filed in connection with its initial public offering. Since the Company’s registration statement became effective on November 20, 2017, it was required to complete an initial business combination by no later than November 20, 2020. The Rule also provides that failure to comply with this requirement will result in the Listing Qualifications Department issuing a Staff Delisting Determination under Rule 5810 to delist the Company’s securities. Liquidity As of December 31, 2020, the Company had $466 in its operating bank account, $5,967,947 in cash and marketable securities held in the Trust Account to be used for a Business Combination or to repurchase or convert stock in connection therewith and an adjusted working capital deficit of $609,509, which excludes prepaid income taxes of $51,642 and prepaid franchise taxes of $30,350, which have been paid from amounts in the Trust Account. As of December 31, 2020, approximately $138,764 of the amount on deposit in the Trust Account represented interest income, which is available to pay the Company’s tax obligations. To date, the Company has withdrawn $716,788 of interest from the Trust Account in order to pay the Company’s franchise and income taxes, of which $161,430 was withdrawn during the year ended December 31, 2020. On November 17, 2018, the Company entered into an agreement (the “Agreement”) with the Sponsor and BRAC, pursuant to which the Sponsor agreed to be responsible for all liabilities of the Company as of November 17, 2018 and to loan the Company the funds necessary to pay the expenses of the Company other than Business Combination expenses through the closing of a Business Combination when and as needed. If a Business Combination is not consummated, all outstanding loans made by the Sponsor will be forgiven (see Note 6). In addition, BRAC agreed to loan the Company all funds necessary to pay expenses incurred in connection with and in order to consummate a business combination (the “Business Combination Expenses”) and such loans will be added to the Initial Notes (as defined in Note 6). If the Company does not consummate a Business Combination, all outstanding loans under the Notes will be forgiven, except to the extent of any funds held outside of the Trust Account after paying all other fees and expenses of the Company incurred prior to the date of such failure to consummate a Business Combination (see Note 6). The Company may raise additional capital through loans or additional investments from the Sponsor or its stockholders, officers, directors, or third parties. Other than as described above, the Company’s officers and directors and the Sponsor may, but are not obligated to, loan the Company funds, from time to time, in whatever amount they deem reasonable in their sole discretion, to meet the Company’s working capital needs. The Company does not believe it will need to raise additional funds in order to meet expenditures required for operating its business. Neither the Sponsor, nor any of the stockholders, officers or directors, or third parties are under any obligation to advance funds to, or invest in, the Company, except as discussed above. Accordingly, the Company may not be able to obtain additional financing. If the Company is unable to raise additional capital, it may be required to take additional measures to conserve liquidity, which could include, but not necessarily be limited to suspending the pursuit of a potential transaction. The Company cannot provide any assurance that new financing will be available to it on commercially acceptable terms, if at all. Even if the Company can obtain sufficient financing or raise additional capital, it only has until April 23, 2021 (or as may be extended) to consummate a Business Combination. There is no assurance that the Company will be able to do so prior to April 23, 2021, or as may be extended by shareholder vote. Risks and Uncertainties Management continues to evaluate the impact of the COVID-19 pandemic 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 financial statements do not include any adjustments that might result from the outcome of this uncertainty. |
