Description of Organization and Business Operations | Note 1—Description of Organization and Business Operations ARYA Sciences Acquisition Corp II (the “Company” or “ARYA”) was incorporated as a Cayman Islands exempted company on February 20, 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. As of June 9, 2020, the Company had not commenced any operations. All activity for the period from February 20, 2020 (inception) through June 9, 2020 relates to the Company’s formation, the initial public offering (the “Initial Public Offering”), which is described below, and identifying a target company for a 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 The Company’s sponsor is ARYA Sciences Holdings II, a Cayman Islands exempted limited company (the “Sponsor”). The registration statement for the Company’s Initial Public Offering was declared effective on June 4, 2020. On June 9, 2020, the Company consummated its Initial Public Offering of 14,950,000 units (the “Units” and, with respect to the Class A ordinary shares included in the Units being offered, the “Public Shares”), including 1,950,000 additional Units to cover over-allotments (the “Over-Allotment Units”), at $10.00 per Unit, 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 (Note 5). Simultaneously with the closing of the Initial Public Offering, the Company consummated the private placement (“Private Placement”) of 499,000 units (each, a “Private Placement Unit” and collectively, the “Private Placement Units”) at a price of $10.00 per Private Placement Unit in a private placement to the Sponsor, generating gross proceeds of approximately $5.0 million (Note 4). Upon the closing of the Initial Public Offering and the Private Placement, $149.5 million ($10.00 per Unit) 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”) and will be invested only in 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 in money market fund meeting the conditions of paragraphs (d)(1), (d)(2), (d)(3) and (d)(4) of Rule 2a-7 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 Units, 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 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 of 1940, as amended (the “Investment Company Act”). The Company will provide the holders (the “Public Shareholders”) of its Class A ordinary shares, par value $0.0001, 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 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 non-public 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 will 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”) have 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 Company’s Public Shares if the Company does not complete its Business Combination within 24 months from the closing of the Initial Public Offering, or June 9, 2022 (the “Combination Period”) or 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 business days thereafter, redeem the Public Shares, at a per-share The initial shareholders have 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 have 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 has agreed to be liable to the Company if and to the extent any claims by a third party 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 trust assets. 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”). 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. On July 29, 2020, the Company entered into a business combination agreement (“Business Combination Agreement”) by and among the Company, Cassidy Merger Sub 1, Inc., a Delaware corporation (“Cassidy Merger Sub”), and Cerevel Therapeutics, Inc., a Delaware corporation (“Cerevel”)., as disclosed in the Form 8-K filed with the SEC on July 30, 2020. The Business Combination Agreement provides for, among other things, the following transactions on the closing date: (i) ARYA will become a Delaware corporation (the “Domestication”) and, in connection with the Domestication, (A) ARYA’s name will be changed to “Cerevel Therapeutics Holdings, Inc.”, (B) each outstanding Class A ordinary share of ARYA and each outstanding Class B ordinary share of ARYA will become one share of common stock of ARYA (the “ARYA Common Stock”), and (C) each outstanding warrant of ARYA will become one warrant to purchase one share of ARYA Common Stock; and (ii) following the Domestication, Cassidy Merger Sub will merge with and into Cerevel, with Cerevel as the surviving company in the merger and, after giving effect to such merger, continuing as a wholly-owned subsidiary of ARYA (the “Merger”). Liquidity As of June 9, 2020, the Company had approximately $1.4 million in its operating bank account, and working capital of approximately $1.4 million. The Company’s liquidity needs to date have been satisfied through a contribution of $25,000 from Sponsor to cover for certain offering costs in exchange for the issuance of the Founder Shares, the loan proceeds of $250,000 from the Sponsor pursuant to the Note (see Note 4), and the proceeds from the consummation of the Private Placement not held in the Trust Account. The Company fully repaid the Note on June 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 June 9, 2020, there were no amounts outstanding under any Working Capital Loan. Based on the foregoing, management believes that the Company will have sufficient working capital and borrowing capacity from the Sponsor or an affiliate of the Sponsor, or certain of the Company’s officers and directors to meet its needs through the earlier of the consummation of a Business Combination or one year from this filing. 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. | Note 1—Description of Organization and Business Operations ARYA Sciences Acquisition Corp II (the “Company” or “ARYA”) was incorporated as a Cayman Islands exempted company on February 20, 2020.
