Ross Acquisition Corp II (the “Company”) was incorporated as a Cayman Islands exempted company on January 19, 2021. 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 or entities (an “Initial Business Combination”).

Ross Acquisition Corp. II has two wholly owned subsidiaries, APRINOIA Therapeutics Merger Sub 2, Inc. (“Merger Sub 2”), an exempted company incorporated with limited liability under the laws of the Cayman Islands, which was formed on December 21, 2022 and APRINOIA Therapeutics Merger Sub 3, Inc. (“Merger Sub 3”), an exempted company incorporated with limited liability under the laws of the Cayman Islands, which was formed on December 21, 2022. Ross Acquisition Corp. II and its subsidiaries are collectively referred to as “the Company”.

The Company’s sponsor is Ross Holding Company LLC, a Cayman Islands limited liability company (the “Sponsor”). The registration statement for the Company’s Initial Public Offering was declared effective on March 11, 2021. On March 16, 2021, the Company consummated its Initial Public Offering of 34,500,000 units (the “Units” and, with respect to the Class A ordinary shares included in the Units being offered, the “Public Shares”), including 4,500,000 additional Units to cover over-allotments (the “Over-Allotment Units”), at $10.00 per Unit, generating gross proceeds of $345.0 million, and incurring offering costs of approximately $19.9 million, of which approximately $12.1 million was for deferred underwriting commissions (see Note 5).

Simultaneously with the closing of the Initial Public Offering, the Company consummated the private placement (“Private Placement”) of 5,933,333 warrants (each, a “Private Placement Warrant” and collectively, the “Private Placement Warrants”), at a price of $1.50 per Private Placement Warrant with the Sponsor, generating gross proceeds of $8.9 million (see Note 4).

Upon the closing of the Initial Public Offering and the Private Placement, $345.0 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 (“Trust Account”), located in the United States with Continental Stock Transfer & Trust Company acting as trustee, and has been only in U.S. “government securities” within the meaning of Section 2(a)(16) of the Investment Company Act of 1940, as amended, or 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, or cash, until the earlier of: (i) the completion of an Initial 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 an Initial Business Combination. There is no assurance that the Company will be able to complete an Initial 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 assets held in the Trust Account (excluding the deferred underwriting commissions and taxes payable on income 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 an Initial Business Combination if the post-transaction company owns or acquires 50% or more of the outstanding voting securities of the target business or otherwise acquires a controlling interest in the target business sufficient for it not to be required to register as an investment company under the Investment Company Act.

The Company will provide the holders of the Public Shares (the “Public Shareholders”) with the opportunity to redeem all or a portion of their Public Shares upon the completion of an Initial Business Combination either (i) in connection with a shareholder meeting called to approve the Initial Business Combination or (ii) by means of a tender offer. The decision as to whether the Company will seek shareholder approval of an Initial 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). 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 were classified as temporary equity in accordance with the Financial Accounting Standards Board’s (“FASB”) Accounting Standards Codification (“ASC”) Topic 480 “Distinguishing Liabilities from Equity.” In such case, the Company will proceed with an Initial Business Combination if the Company has net tangible assets of at least $5,000,001 upon such consummation of an Initial Business Combination and a majority of the shares voted are voted in favor of the Initial 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 legal reasons, the Company will, pursuant to the amended and restated memorandum and articles of association which was adopted upon the consummation of the Initial Public Offering, as amended (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 an Initial Business Combination. If, however, shareholder approval of the transactions is required by law, or the Company decides to obtain shareholder approval for business or 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. Additionally, each Public Shareholder may elect to redeem their Public Shares irrespective of whether they vote for or against the proposed transaction. If the Company seeks shareholder approval in connection with an Initial Business Combination, the initial shareholders (as defined below) 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 an Initial Business Combination. Subsequent to the consummation of the Initial Public Offering, the Company adopted an insider trading policy which requires 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 and Public Shares in connection with the completion of an Initial Business Combination.

Notwithstanding the foregoing, the Amended and Restated Memorandum and Articles of Association provides 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% or more of the Class A ordinary shares sold in the Initial Public Offering, without the prior consent of the Company.

If the Company is unable to complete an Initial 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 price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account, including interest earned on the funds held in the Trust Account and not previously released to the Company to pay its tax obligations, if any (less up to $100,000 of interest to pay dissolution expenses) divided by the number of the then-outstanding Public Shares, which redemption will completely extinguish Public Shareholders’ rights as shareholders (including the right to receive further liquidation distributions, if any); and (iii) as promptly as reasonably possible following such redemption, subject to the approval of the remaining shareholders and the board of directors, liquidate and dissolve, subject in the case of clauses (ii) and (iii), to the Company’s obligations under Cayman Islands law to provide for claims of creditors and the requirements of other applicable law.

Terminated Business Combination

Risks and Uncertainties

The Company’s liquidity needs through September 30, 2023 and prior were satisfied through a payment of $25,000 from the Sponsor to purchase certain expenses in exchange for the issuance of the Founder Shares, the loan of approximately $90,000 from the Sponsor under the Note (as defined in Note 5), and the proceeds from the consummation of the Private Placement not held in the Trust Account. The Company repaid the Note in full on March 19, 2021. In addition, in order to finance transaction costs in connection with an Initial 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 5).

On March 16, 2021, the Company consummated its Initial Public Offering of 34,500,000 Units, including the issuance of 4,500,000 Over-Allotment Units, as a result of the underwriter’s partial exercise of its over-allotment option, at $10.00 per Unit, generating gross proceeds of $345.0 million, and incurring offering costs of approximately $19.9 million, of which approximately $12.1 million was for deferred underwriting commissions.

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

On January 22, 2021, the Sponsor paid $25,000 to cover certain expenses on behalf of the Company in exchange for issuance of 8,625,000 Class B ordinary shares, par value $0.0001 (the “Founder Shares”). The Sponsor agreed to forfeit up to 1,125,000 Founder Shares to the extent that the over-allotment option was 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. On March 16, 2021, the underwriter fully exercised its over-allotment option; thus, these 1,125,000 Founder Shares were no longer subject to forfeiture.

The initial shareholders agreed, subject to limited exceptions, not to transfer, assign or sell any of their Founder Shares until the earlier to occur of: (A) one year after the completion of an Initial Business Combination and (B) subsequent to an Initial Business Combination, (x) if the closing price of the Class A ordinary shares equals or exceeds $12.00 per share (as adjusted for share subdivisions, share capitalizations, 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, share exchange or other similar transaction that results in all of the Public Shareholders having the right to exchange their ordinary shares 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 5,933,333 Private Placement Warrants, at a price of $1.50 per Private Placement Warrant with the Sponsor, generating gross proceeds of $8.9 million.

Each whole Private Placement Warrant is exercisable for one whole Class A ordinary share at a price of $11.50 per share. A portion of the proceeds from the Private Placement Warrants was added to the proceeds from the Initial Public Offering held in the Trust Account. If the Company does not complete an Initial Business Combination within the Combination Period, the Private Placement Warrants will expire worthless. The Private Placement Warrants will be non-redeemable and exercisable on a cashless basis so long as they are held by the Sponsor or its permitted transferees.

 

The Sponsor and the Company’s officers and directors agreed, subject to limited exceptions, not to transfer, assign or sell any of their Private Placement Warrants until 30 days after the completion of an Initial Business Combination.

Related Party Loans

On January 21, 2021, the Sponsor agreed to loan the Company an aggregate of up to $300,000 to cover for 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. As of March 16, 2021, the Company borrowed approximately $90,000 under the Note. The Company repaid the Note in full on March 19, 2021. Subsequent to the repayment, the facility was no longer available to the Company.

In order to finance transaction costs in connection with an Initial Business Combination, the Sponsor or an affiliate of the Sponsor, or certain of the Company’s officers and directors may loan the Company funds as may be required (“Working Capital Loans”). On November 14, 2023, to document existing and future Working Capital Loans, the Company issued the Convertible Note, an unsecured, convertible promissory note, to the Sponsor, pursuant to which the Company can borrow up to $1,500,000 from the Sponsor, for ongoing expenses reasonably related to the business of the Company and the consummation of a Business Combination. All unpaid principal under the Convertible Note will be due and payable in full on the Maturity Date, which is the earlier of (i) March 16, 2024, or such later date by which the Company must consummate a Business Combination pursuant to its Amended and Restated Memorandum and Articles of Association (as may be amended by shareholder vote) and (ii) the effective date of a Business Combination. The Sponsor has the option, at any time on or prior to the Maturity Date, to convert any amounts outstanding under the Convertible Note, up to an aggregate amount of $1,500,000, into warrants to purchase Class A ordinary shares of the Company, at a conversion price of $1.50 per warrant, with each warrant entitling the holder to purchase one Class A ordinary share at a price of $11.50 per share, subject to the same adjustments applicable to the Private Placement Warrants sold concurrently with the Company’s Initial Public Offering. If the Company completes an Initial 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 an Initial Business Combination does not close, the Company may use a portion of the 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. 

If the Company is required to seek additional capital, the Company would need to borrow additional funds from the Sponsor, the Company’s management team or other third parties to operate or may be forced to liquidate. Except with respect to the Extension Note and the Convertible Note, none of the Sponsor, members of the management team nor any of their affiliates is under any obligation to advance funds to the Company in such circumstances.

Administrative Support Agreement

Registration and Shareholder Rights

The holders of the Founder Shares, Private Placement Warrants and warrants that may be issued upon conversion of the Working Capital Loans, if any, were entitled to registration rights pursuant to a registration and shareholder rights agreement signed upon consummation of the Initial Public Offering. These holders were entitled to certain demand and “piggyback” registration rights. However, the registration and shareholder rights agreement provided that the Company would not permit any registration statement filed under the Securities Act to become effective until the termination of the applicable lock-up period for the securities to be registered. The Company will bear the expenses incurred in connection with the filing of any such registration statements.

Underwriting Agreement

The Company granted the underwriters a 45-day option from the final prospectus relating to the Initial Public Offering to purchase up to 4,500,000 additional Units to cover over-allotments, if any, at the Initial Public Offering price less the underwriting discounts and commissions. On March 16, 2021, the underwriter fully exercised its over-allotment option.

The underwriters were entitled to an underwriting discount of $0.20 per unit, or approximately $6.9 million in the aggregate, paid upon the closing of the Initial Public Offering. In addition, $0.35 per unit, or approximately $12.1 million in the aggregate will be payable to the underwriters for deferred underwriting commissions. The deferred fee will become payable to the underwriters from the amounts held in the Trust Account solely in the event that the Company completes an Initial Business Combination, subject to the terms of the underwriting agreement.

On January 19, 2023, the Company received a waiver of underwriter fees from one of the underwriters in which the underwriter  waived its entitlement to the payment of any deferred underwriting commission to be paid under the terms of the underwriting agreement. As such, $6,037,500, has been forgiven of which $5,579,875 is presented in the unaudited condensed consolidated statement of changes in shareholders deficit and $457,625 is recognized as a gain on the waiver on the condensed consolidated statement of operations.

On January 23, 2023, the Company received a waiver of underwriter fees from a second underwriter in which the underwriter waived the right to receive its deferred underwriting commissions payable upon the consummation of the Business Combination under the terms of the underwriting agreement. The second underwriter did not waive the right to receive its deferred underwriting commission payable upon the consummation of any other Initial Business Combination.

The Company’s Class A ordinary shares feature certain redemption rights that are considered to be outside of the Company’s control and subject to the occurrence of future events. The Company is authorized to issue 100,000,000 Class A ordinary shares with a par value of $0.0001 per share. Holders of the Company’s Class A ordinary shares are entitled to one vote for each share. In connection with the vote to approve the First Extension Amendment Proposal, the holders of 28,119,098 Class A ordinary shares of the Company properly exercised their right to redeem their shares for cash at a redemption price of approximately $10.23 per share, for an aggregate redemption amount of approximately $287.7 million. As of September 30, 2023 and December 31, 2022, there were 5,041,098 and 34,500,000 Class A ordinary shares outstanding, which were all subject to possible redemption and are classified outside of permanent equity in the condensed consolidated balance sheets, respectively.

Holders of the Class A ordinary shares and holders of the Class B ordinary shares will vote together as a single class on all matters submitted to a vote of the shareholders, except as required by law or stock exchange rule; provided that only holders of the Class B ordinary shares have the right to vote on the election of the Company’s directors prior to the Initial Business Combination.

The Class B ordinary shares will automatically convert into Class A ordinary shares at the time of the Initial Business Combination at a ratio such that the number of Class A ordinary shares issuable upon conversion of all Founder Shares will equal, in the aggregate, on an as-converted basis, 20% of the sum of (i) the total number of ordinary shares issued and outstanding upon completion of the Initial Public Offering, plus (ii) the total number of Class A ordinary shares issued or deemed issued or issuable upon conversion or exercise of any equity-linked securities or rights issued or deemed issued, by the Company in connection with or in relation to the consummation of the Initial Business Combination, excluding any Class A ordinary shares or equity-linked securities exercisable for or convertible into Class A ordinary shares issued, deemed issued, or to be issued, to any seller in the Initial Business Combination and any Private Placement Warrants issued to the Sponsor, its affiliates or any member of the Company’s management team upon conversion of Working Capital Loans. In no event will the Class B ordinary shares convert into Class A ordinary shares at a rate of less than one-to-one.

As of September 30, 2023 and December 31, 2022, the Company had 11,500,000 Public Warrants and 5,933,333 Private Placement Warrants outstanding. Public Warrants may only be exercised for a whole number of shares.

The Public Warrants will become exercisable on the later of (a) 30 days after the completion of an Initial Business Combination or (b) 12 months from the closing of the Initial Public Offering; provided in each case that the Company has an effective registration statement under the Securities Act covering the Class A ordinary shares issuable upon exercise of the Public Warrants and a current prospectus relating to them is available (or the Company permits holders to exercise their Public Warrants on a cashless basis and such cashless exercise is exempt from registration under the Securities Act). The Company agreed that as soon as practicable, but in no event later than twenty business days after the closing of the Initial Business Combination, the Company will use its commercially reasonable efforts to file with the SEC a registration statement covering the Class A ordinary shares issuable upon exercise of the warrants, and the Company will use its commercially reasonable efforts to cause the same to become effective within 60 business days after the closing of the Initial Business Combination, and to maintain the effectiveness of such registration statement and a current prospectus relating to those Class A ordinary shares until the warrants expire or are redeemed, as specified in the warrant agreement provided that if the Class A ordinary shares are at the time of any exercise of a warrant not listed on a national securities exchange such that they satisfy the definition of a “covered security” under Section 18(b)(1) of the Securities Act, the Company may, at its option, require holders of Public Warrants who exercise their warrants to do so on a “cashless basis” in accordance with Section 3(a)(9) of the Securities Act and, in the event the Company so elects, it will not be required to file or maintain in effect a registration statement. If a registration statement covering the Class A ordinary shares issuable upon exercise of the warrants is not effective by the 60th day after the closing of the Initial Business Combination, warrant holders may, until such time as there is an effective registration statement and during any period when the Company will have failed to maintain an effective registration statement, exercise warrants on a “cashless basis” in accordance with Section 3(a)(9) of the Securities Act or another exemption, but the Company will use its commercially reasonable efforts to register or qualify the shares under applicable blue sky laws to the extent an exemption is not available.

The warrants have an exercise price of $11.50 per whole share and will expire five years after the completion of an Initial Business Combination or earlier upon redemption or liquidation.

In addition, if (x) the Company issues additional Class A ordinary shares or equity-linked securities for capital raising purposes in connection with the closing of the Initial Business Combination at an issue price or effective issue price of less than $9.20 per ordinary share (with such issue price or effective issue price to be determined in good faith by the Company’s board of directors and, in the case of any such issuance to the Sponsor or its affiliates, without taking into account any Founder Shares held by the Sponsor or such affiliates, as applicable, prior to such issuance) (the “Newly Issued Price”), (y) the aggregate gross proceeds from such issuances represent more than 60% of the total equity proceeds, and interest thereon, available for the funding of Initial Business Combination on the date of the consummation of the Initial Business Combination (net of redemptions), and (z) the volume weighted average trading price of the Class A ordinary shares during the 20 trading day period starting on the trading day prior to the day on which the Company consummates its Initial Business Combination (such price, the “Market Value”) is below $9.20 per share, the exercise price of the warrants will be adjusted (to the nearest cent) to be equal to 115% of the higher of the Market Value and the Newly Issued Price, the $18.00 per share redemption trigger price described below under “Redemption of warrants when the price per Class A ordinary share equals or exceeds $18.00” and “Redemption of warrants when the price per Class A ordinary share equals or exceeds $10.00” will be adjusted (to the nearest cent) to be equal to 180% of the higher of the Market Value and the Newly Issued Price, and the $10.00 per share redemption trigger price described below under “Redemption of warrants when the price per Class A ordinary share equals or exceeds $10.00” will be adjusted (to the nearest cent) to be equal to the higher of the Market Value and the Newly Issued Price.

Redemption of warrants for cash when the price per Class A ordinary share equals or exceeds $18.00.

Once the warrants become exercisable, the Company may redeem the Public Warrants for cash (except with respect to the Private Placement Warrants):

If and when the warrants become redeemable by the Company, the Company may exercise its redemption right even if it is unable to register or qualify the underlying securities for sale under all applicable state securities laws. If the Company calls the Public Warrants for redemption, as described above, management will have the option to require any holder that wishes to exercise the Public Warrants to do so on a “cashless basis,” as described in the warrant agreement. Except as set forth below, none of the private placement warrants will be redeemable by us so long as they are held by the Sponsor or its permitted transferees.

Redemption of warrants for Class A ordinary shares when the price per Class A ordinary share equals or exceeds $10.00.

Once the warrants become exercisable, the Company may redeem the outstanding Public Warrants:

The “fair market value” of the Class A ordinary shares for the above purpose shall mean the volume weighted average price of the Class A ordinary shares during the ten trading days immediately following the date on which the notice of redemption is sent to the holders of warrants. In no event will the warrants be exercisable in connection with this redemption feature for more than 0.361 Class A ordinary shares per warrant (subject to adjustment).

If the Company has not completed the Initial Business Combination within the Combination Period and the Company liquidates the funds held in the Trust Account, holders of warrants will not receive any of such funds with respect to their warrants, nor will they receive any distribution from the Company’s assets held outside of the Trust Account with the respect to such warrants. Accordingly, the warrants may expire worthless.

Note 9 - Fair Value Measurements

Transfers to/from Levels 1, 2, and 3 are recognized at the beginning of the reporting period. The estimated fair value of Public Warrants was transferred from a Level 3 measurement to a Level 1 measurement, when the Public Warrants were separately listed and traded in an active market in May 2021. The estimated fair value of the Private Warrants was transferred from a Level 3 measurement to a Level 2 fair value measurement as of May 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. The estimated fair value of the Public Warrants transferred from a Level 1 measurement to a Level 2 fair value measurement, due to lack of activity, during the nine months ended September 30, 2023 was $1,265,000.
