Description of Organization and Business Operations | Note 1 - Description of Organization and Business Operations ARYA Sciences Acquisition Corp IV (the “Company”) was incorporated as a Cayman Islands exempted company on August 24, 2020. The Company was formed for the purpose of effecting a merger, share exchange, asset acquisition, share 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. All activity for the period from August 24, 2020 (inception) through September 30, 2023 was related to the Company’s formation and initial public offering (the “Initial Public Offering”) described below, and since 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 income earned on investments or cash held in the Trust Account (as defined below) from the proceeds derived from the Initial Public Offering. The Company has selected December 31 as its fiscal year end. The Company’s sponsor is ARYA Sciences Holdings IV, a Cayman Islands exempted limited company (the “Sponsor”). The registration statement for the Company’s Initial Public Offering was declared effective on February 25, 2021. On March 2, 2021, the Company consummated its Initial Public Offering of 14,950,000 Class A ordinary shares (the “Public Shares”), including the 1,950,000 Public Shares as a result of the underwriters’ full exercise of their over-allotment option, at an offering price of $10.00 per Public Share, generating gross proceeds of $149.5 million, and incurring offering costs of approximately $8.8 million, inclusive of approximately $5.2 million in deferred underwriting commissions (see Note 5). On August 8, 2022, the Company received a waiver from one of the underwriters of its Initial Public Offering pursuant to which such underwriter waived all rights to its 50% share of the deferred underwriting commissions payable upon completion of an initial Business Combination. In connection with this waiver, the underwriter also agreed that (i) this waiver is not intended to allocate its 50% portion of the deferred underwriting commissions to the other underwriter that has not waived its right to receive its share of the deferred underwriting commissions and (ii) the waived portion of the deferred underwriting commissions can, at the discretion of the Company, be paid to one or more parties or otherwise be used in connection with an initial Business Combination. Simultaneously with the closing of the Initial Public Offering, the Company consummated the private placement (“Private Placement”) of 499,000 Class A ordinary shares (the “Private Placement Shares”), at a price of $10.00 per Private Placement Share to the Sponsor, generating gross proceeds of approximately $5.0 million (see Note 4). Upon the closing of the Initial Public Offering and the Private Placement, $149.5 million ($10.00 per Public Share) of the net proceeds of the Initial Public Offering and certain of the proceeds of the Private Placement were placed in a trust account (the “Trust Account”), located in the United States, with Continental Stock Transfer & Trust Company acting as trustee, and were invested only in United States “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, until the earlier of (i) the completion of a Business Combination and (ii) the distribution of the Trust Account as described below. On February 27, 2023, the Company delivered an instruction letter to Continental Stock Transfer & Trust Company acting, as trustee, to liquidate the investments held in the Trust Account and instead to hold the funds in the Trust Account in cash in an interest-bearing demand deposit account until the earlier of the consummation of an initial Business Combination or the Company’s liquidation. The Company is taking these steps in order to mitigate the risk that the Company might be deemed to be an investment company for purposes of the Investment Company Act following the adoption of the Extension Amendment Proposal described below. For more information on the partial liquidation of the Trust Account in connection with the adoption of the Extension Amendment Proposal and the related redemption of Class A ordinary shares, see 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 Shares, 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 (excluding the amount of deferred underwriting commissions and taxes payable on the interest earned on the Trust Account) at the time of the signing of the agreement to enter into the initial Business Combination. However, the Company will only complete a Business Combination if the post-transaction 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. The Company will provide the holders (the “Public Shareholders”) of 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 shareholder meeting called to approve the Business Combination or (ii) by means of a tender offer. The decision as to whether the Company will seek shareholder approval of a Business Combination or conduct a tender offer will be made by the Company, solely in its discretion. The Public Shareholders will be entitled to redeem their Public Shares for a pro rata portion of the amount then in the Trust Account (initially anticipated to be $10.00 per Public Share, plus any pro rata interest earned on the funds held in the Trust Account and not previously released to the Company to pay income taxes). The per-share amount to be distributed to Public Shareholders 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 are classified as temporary equity upon the completion of the Initial Public Offering in accordance with the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 480, “Distinguishing Liabilities from Equity” (“ASC 480”). In such case, 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, only if a majority of the ordinary shares, represented in person or by proxy and entitled to vote thereon, voted at a shareholder meeting are voted in favor of the Business Combination. If a shareholder vote is not required by law and the Company does not decide to hold a shareholder vote for business or other reasons, the Company will, pursuant to the amended and restated memorandum and articles of association which the Company adopted upon the consummation of the Initial Public Offering and subsequently amended in connection with the adoption of Extension Amendment Proposal described below (the “Amended and Restated Memorandum and Articles of Association”), conduct the redemptions pursuant to the tender offer rules of the U.S. Securities and Exchange Commission (“SEC”) and file tender offer documents with the SEC prior to completing a Business Combination. If, however, shareholder approval of the transactions is required by law, or the Company decides to obtain shareholder approval for business or other 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. Additionally, each Public Shareholder may elect to redeem their Public Shares irrespective of whether they vote for or against the proposed transaction or vote at all. If the Company seeks shareholder approval in connection with a Business Combination, the initial shareholders (as defined below) agreed to vote their Founder Shares (as defined below in Note 4) and any Public Shares they hold in favor of a Business Combination. Subsequent to the consummation of the Initial Public Offering, the Company will adopt an insider trading policy which will require insiders to (i) refrain from purchasing shares during certain blackout periods and when they are in possession of any material non-public information and (ii) to clear all trades with the Company’s legal counsel prior to execution. In addition, the initial shareholders agreed to waive their redemption rights with respect to their Founder Shares, Private Placement Shares and Public Shares in connection with the completion of a Business Combination. Notwithstanding the foregoing, if the Company seeks shareholder approval of its Business Combination and does not conduct redemptions in connection with its Business Combination pursuant to the tender offer rules, the Amended and Restated Memorandum and Articles of Association provide that a Public Shareholder, together with any affiliate of such shareholder or any other person with whom such shareholder 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 Class A ordinary shares sold in the Initial Public Offering, without the prior consent of the Company. The Company’s Sponsor, officers and directors (the “initial shareholders”) agreed not to propose an amendment to the Amended and Restated Memorandum and Articles of Association (a) that would modify the substance or timing of the Company’s obligation to provide holders of its Public Shares the right to have their shares redeemed in connection with a Business Combination or to redeem 100% of the Public Shares if the Company does not complete its Business Combination within the time period during which the Company is required to consummate a Business Combination pursuant to the Amended and Restated Memorandum and Articles of Association (the “Combination Period”), or (b) with respect to any other provision relating to the rights of Public Shareholders, unless the Company provides the Public Shareholders with the opportunity to redeem their Class A ordinary shares in conjunction with any such amendment. If the Company has not completed a Business Combination within the Combination Period, the Company will (i) cease all operations except for the purpose of winding up; (ii) as promptly as reasonably possible but not more than ten The initial shareholders agreed to waive their liquidation rights with respect to the Founder Shares and Private Placement Shares held by them if the Company fails to complete a Business Combination within the Combination Period. However, if the initial shareholders 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 agreed to waive their rights to their 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 assets remaining available for distribution (including Trust Account assets) will be only $10.00 per share initially held in the Trust Account. In order to protect the amounts held in the Trust Account, the Sponsor agreed to be liable to the Company if and to the extent any claims by a third party (excluding 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, reduce the amount of funds in the Trust Account to below the lesser of (i) $10.00 per Public Share and (ii) the actual amount per Public Share held in the Trust Account as of the date of the liquidation of the Trust Account if less than $10.00 per Public Share due to reductions in the value of the assets in the Trust Account, in each case net of the interest that may be withdrawn to pay for the Company’s tax obligations. This liability will not apply with respect to any claims by a third party who executed a waiver of any right, title, interest or claim of any kind in or to any monies held in the Trust Account or 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”). On February 28, 2023, the Company held an extraordinary general meeting of shareholders in view of approving an amendment to its Amended and Restated Memorandum and Articles of Association to extend the date (the “Termination Date”) by which the Company has to consummate a Business Combination from March 2, 2023 (the “Original Termination Date”) to June 2, 2023 (the “Articles Extension Date”) and to allow the Company, without another shareholder vote, to elect to extend the Termination Date to consummate a Business Combination on a monthly basis for up to nine times by an additional one month each time after the Articles Extension Date, by resolution of the Company’s board of directors, if requested by the Sponsor, and upon five days’ advance notice prior to the applicable Termination Date, until March 2, 2024 or a total of up to thirty-six The Company approved one-month extensions on June 2, 2023, July 2, 2023, August 2, 2023, September 2, 2023, October 2, 2023 and November 2, 2023 (the “Extensions”). Pursuant to such extensions, the Company has until December 2, 2023 to consummate an initial Business Combination (such time period, the “Business Combination Period”). In connection with the extensions on June 2, 2023, July 2, 2023, August 2, 2023, and September 2, 2023, the Company drew an aggregate amount of $560,000 (the “Extension Funds”) from the Second Convertible Promissory Note in the principal amount of up to $1,680,000. In connection with the extensions on October 2, 2023 and November 2, 2023, the Company drew an aggregate amount of $280,000 from the Third Promissory Note (as defined below). The Company drew additional funds under the Second Convertible Promissory Note and the Third Promissory Note in view of funding the Company’s ongoing working capital (for more information see Note 4). As contemplated by the Amended and Restated Memorandum and Articles of Association, the holders of Public Shares were able to elect to redeem all or a portion of their Public Shares in exchange for their pro rata portion of the funds held in the Trust Account in connection with the Extension Amendment Proposal. On February 28, 2023, the Extension Amendment Proposal was adopted and 11,259,169 Public Shares were redeemed for an aggregate amount of $115,071,882. Following the adoption of the Extension Amendment Proposal, the Company has 4,189,831 Class A ordinary shares, including 3,690,831 Public Shares and 499,000 Private Placement Shares, and 3,737,500 Class B ordinary shares issued and outstanding. Following the approval of the Extension Amendment Proposal, the Class B ordinary shares held by the initial shareholders represent 47.1% of the issued and outstanding ordinary shares. Moreover, in the event that an executed waiver is deemed to be unenforceable against a third party, the 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 (excluding 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. The Company has not asked the Sponsor to reserve for such indemnification obligations, nor has the Company independently verified whether the Sponsor has sufficient funds to satisfy its indemnity obligations and the Company believes that the Sponsor’s only assets are securities of the Company. The Sponsor may not be able to satisfy those obligations. None of the Company’s officers or directors will indemnify the Company for claims by third parties including, without limitation, claims by vendors and prospective target businesses. Going Concern As of September The Company’s liquidity needs to date have been satisfied through a contribution of $25,000 from Sponsor to cover for certain expenses in exchange for the issuance of the Founder Shares, the loan of approximately $161,000 from the Sponsor pursuant to the Note (as defined in Note 4), the proceeds from the consummation of the Private Placement not held in the Trust Account, the First Convertible Promissory Note and the Second Convertible Promissory Note. The Company fully repaid the Note upon closing of the Initial Public Offering. 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 (as defined in Note 4). As of September borrowings outstanding The Company cannot provide any assurance that new financing along the lines detailed above will be available to it on commercially acceptable terms, if at all. Further, the Company has until the end of the Combination Period to consummate a Business Combination, but the Company cannot provide assurance that it will be able to consummate a Business Combination by that date. If a Business Combination is not consummated by the required date, there will be a mandatory liquidation and subsequent dissolution. In connection with the Company’s assessment of going concern considerations in accordance with FASB ASC Topic 205-40, “Basis of Presentation - Going Concern,” management has determined that the working capital deficit and mandatory liquidation and subsequent dissolution raises substantial doubt about the Company’s ability to continue as a going concern until the earlier of the consummation of the 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. The Company intends to complete its initial Business Combination before the mandatory liquidation date; however, there can be no assurance that the Company will be able to consummate any Business Combination by the end of the Combination Period. No adjustments have been made to the carrying amounts of assets and liabilities should the Company be required to liquidate after the end of the Combination Period, nor do these unaudited condensed financial statements include any adjustments relating to the recovery of the recorded assets or the classification of the liabilities that might be necessary should the Company be unable to continue as a going concern. Risks and Uncertainties Results of operations and the Company’s ability to complete a Business Combination may be adversely affected by various factors that could cause economic uncertainty and volatility in the financial markets, many of which are beyond its control. The Company’s business of pursuing and consummating an initial Business Combination could be impacted by, among other things, downturns in the financial markets or in economic conditions, export controls, tariffs, trade wars, inflation, increases in interest rates, supply chain disruptions, declines in consumer confidence and spending, the ongoing effects of the COVID-19 pandemic, including resurgences and the emergence of new variants, and geopolitical instability, such as the military conflict in the Ukraine The Company cannot at this time fully predict the likelihood of one or more of the above events, their duration or magnitude or the extent to which they may materially impact the Company’s business and its ability to complete an initial Business Combination. |
