NOTE 1. DESCRIPTION OF ORGANIZATION AND BUSINESS OPERATIONS

Black Spade Acquisition II Co (the “Company”) was incorporated in the Cayman Islands on May 9, 2024. The Company was formed for the purpose of effecting a merger, capital share exchange, asset acquisition, share purchase, reorganization or similar business combination with one or more businesses (the “Business Combination”). The Company is not limited to a particular industry or sector for purposes of consummating a Business Combination. The Company is an early stage and emerging growth company, and, as such, the Company is subject to all of the risks associated with early stage and emerging growth companies.

As of June 30, 2024, the Company had not commenced any operations. All activity for the period from May 9, 2024 (inception) through June 30, 2024 relates to the Company’s formation and the initial public offering (“Initial Public Offering”), which is described below. The Company will not generate any operating revenues until after the completion of its initial Business Combination, at the earliest. The Company will generate non-operating income in the form of interest income from the proceeds derived from the Initial Public Offering. The Company has selected December 31 as its fiscal year end.

The registration statement for the Company’s Initial Public Offering was declared effective on August 23, 2024. On August 29, 2024, the Company consummated the Initial Public Offering of 15,000,000 units (the “Units” and, with respect to the Class A ordinary shares included in the Units being offered, the “Public Shares”) at $10.00 per Unit, generating gross proceeds of $150,000,000, which is discussed in Note 3.

Simultaneously with the closing of the Initial Public Offering, the Company consummated the sale of 11,000,000 warrants (the “Private Placement Warrants”) at a price of $0.50 per Private Placement Warrant, in a private placement to Black Spade Sponsor LLC II, the Company’s sponsor (the “Sponsor”), generating gross proceeds of $5,500,000, which is described in Note 4.

The Company had granted the underwriters in the Initial Public Offering, a 45-day option to purchase up to 2.250,000 additional Units to cover over-allotments, if any (“Over-Allotment Units”). On September 26, 2024, the underwriters exercised a portion of the option and purchased 300,000 Over-Allotment Units, generating gross proceeds of $3,000,000. In connection with the partial exercise of the over-allotment option, the Sponsor purchased an additional 120,000 Private Placement Warrants at a purchase price of $0.50 per Private Placement Warrant, generating additional gross proceeds to the Company of $60,000. The underwriters have forfeited the option to purchase the remaining 1,950,000 Units.

Transaction costs amounted to $7,395,804, consisting of $2,660,000 of cash underwriting fee (net of $400,000 underwriters’ reimbursement), $4,257,000 of deferred underwriting fee (see additional discussion in Note 6), and $478,804 of other offering costs.

The Company’s management has broad discretion with respect to the specific application of the net proceeds of the Proposed Public Offering and the sale of Private Placement Warrants, although substantially all of the net proceeds are intended to be applied generally toward consummating a Business Combination. There is no assurance that the Company will be able to complete a Business Combination successfully.

The Company must complete one or more initial Business Combinations with one or more operating businesses or assets with a fair market value equal to at least 80% of the net assets held in the Trust Account (as defined below) (excluding the deferred underwriting commissions on the Trust Account). 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 business 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”).

Following the closing of the Initial Public Offering, on August 29, 2024, and the partial over-allotment close on September 26, 2024, an amount of $153,000,000 ($10.00 per Unit) from the net proceeds of the sale of the Units and the sale of the Private Placement Warrants was placed in the trust account (the “Trust Account”), located in the United States and 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 any money market fund selected by the Company meeting certain conditions of Rule 2a-7 of the Investment Company Act and/or held

NOTE 3. INITIAL PUBLIC OFFERING

Pursuant to the Initial Public Offering, on August 29, 2024, the Company sold 15,000,000 Units, at a price of $10.00 per Unit. On September 26, 2024, the underwriters purchased an additional 300,000 Units pursuant to the partial exercise of the over-allotment option. The Units were sold at an offering price of $10.00 per Unit, generating additional gross proceeds to the Company of $3,000,000.

Each Unit consists of one Class A ordinary share and one-third of one redeemable warrant (“Public Warrant”). Each whole Public Warrant entitles the holder to purchase one Class A ordinary share at a price of $11.50 per share, subject to adjustment (see Note 7). Only whole warrants are exercisable. No fractional warrants will be issued upon separation of the units and only whole warrants will trade. The warrants will become exercisable on the later of 30 days after the completion of the initial Business Combination or 12 months from the closing of the Initial Public Offering and will expire five years after the completion of the initial Business Combination or earlier upon redemption or liquidation.

NOTE 4. PRIVATE PLACEMENT

Simultaneously with the closing of the Initial Public Offering, the Sponsor purchased an aggregate of 11,000,000 Private Placement Warrants at a price of $0.50 per Private Placement Warrant ($5,500,000 in the aggregate). In connection with the partial exercise of the over-allotment option, the Sponsor purchased an additional 120,000 Private Placement Warrants at a purchase price of $0.50 per Private Placement Warrant, generating additional gross proceeds to the Company of $60,000. Each Private Placement Warrant is exercisable to purchase one Class A ordinary share at a price of $11.50 per share, subject to adjustment (see Note 7). The proceeds from the sale of the Private Placement Warrants were added to the net proceeds from the Initial Public Offering held in the Trust Account. If the Company does not complete a Business Combination within the Combination Period, the proceeds from the sale of the Private Placement Warrants held in the Trust Account will be used to fund the redemption of the Public Shares (subject to the requirements of applicable law) and the Private Placement Warrants will expire worthless. The Private Placement Warrants (including the Class A ordinary shares issuable

Founder Shares

On May 21, 2024, the Sponsor purchased 4,312,500 of the Company’s Class B ordinary shares (the “Founder Shares”) in exchange for a capital contribution of $25,000 that was paid by the Sponsor for deferred offering costs. The Founder Shares include an aggregate of up to 562,500 shares subject to forfeiture to the extent that the underwriters’ over-allotment is not exercised in full or in part, so that the number of Founder Shares will equal, on an as-converted basis, approximately 20% of the Company’s issued and outstanding ordinary shares after the Initial Public Offering. On September 26, 2024, the underwriters partially exercised their over-allotment option and purchased an additional 300,000 Units. Due to the partial exercise and the decision to forfeit the remaining option, 487,500 Class B ordinary shares were forfeited and the Sponsor subsequently holds 3,825,000 Founder Shares.

On August 20, 2024, the Sponsor transferred a total of 630,000 Founder Shares to directors, officers and certain employees of Sponsor’s affiliates, at a price of $0.006 per share. The sale of the Founders Shares to each of the directors, officers and certain employees of Sponsor’s affiliates is in the scope of FASB ASC Topic 718, “Compensation-Stock Compensation” (“ASC 718”). Under ASC 718, stock-based compensation associated with equity-classified awards is measured at fair value upon the grant date. The fair value of the 630,000 shares granted to the directors, officers and certain employees of Sponsor’s affiliates was $1,096,200 or $1.74 per share. The Founders Shares were granted subject to a performance condition (i.e., the occurrence of a Business Combination). Compensation expense related to the Founders Shares is recognized only when the performance condition is probable of occurrence under the applicable accounting literature in this circumstance. As of June 30, 2024, the Company determined that a Business Combination is not considered probable, and, therefore, no stock-based compensation expense has been recognized. Stock-based compensation would be recognized at the date a Business Combination is considered probable (i.e., upon consummation of a Business Combination) in an amount equal to the number of Founders Shares times the grant date fair value per share (unless subsequently modified) less the amount initially received for the purchase of the Founders Shares.

The Sponsor has agreed, subject to limited exceptions, not to transfer, assign or sell any of the Founder Shares until the earlier to occur of (A) six months after the completion of the initial Business Combination or earlier if, subsequent to the initial Business Combination, 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, and (B) the date following the completion of the initial Business Combination on which the Company completes a liquidation, merger, share exchange or other similar transaction that results in all of the shareholders having the right to exchange their Class A ordinary shares for cash, securities or other property.

Promissory Note — Related Party

On May 21, 2024, the Sponsor issued an unsecured promissory note to the Company (the “Promissory Note”), pursuant to which the Company may borrow up to an aggregate principal amount of $250,000. The Promissory Note is non-interest bearing and payable on the earlier of (i) December 31, 2024 or (ii) the consummation of the Initial Public Offering. As of June 30, 2024, there was $78,488 outstanding borrowings under the Promissory Note. The Promissory Note has been repaid post the closing of the Initial Public Offering, on September 5, 2024.

Administrative Services Agreement

The Company entered into an agreement, commencing on August 23, 2024, through the earlier of the consummation of the initial Business Combination and liquidation, to pay the Sponsor $20,000 per month for office space, utilities and secretarial and administrative support services.

NOTE 6. COMMITMENTS AND CONTINGENCIES

Risk and Uncertainties

The United States and global markets are experiencing volatility and disruption following the geopolitical instability resulting from the ongoing Russia-Ukraine conflict and the recent escalation of the Israel-Hamas conflict. In response to the ongoing Russia-Ukraine conflict, the North Atlantic Treaty Organization (“NATO”) deployed additional military forces to eastern Europe, and the United States, the United Kingdom, the European Union and other countries have announced various sanctions and restrictive actions against Russia, Belarus and related individuals and entities, including the removal of certain financial institutions from the Society for Worldwide Interbank Financial Telecommunication payment system. Certain countries, including the United States, have also provided and may continue to provide military aid or other assistance to Ukraine and to Israel, increasing geopolitical tensions among a number of nations. The invasion of Ukraine by Russia and the escalation of the Israel-Hamas conflict and the resulting measures that have been taken, and could be taken in the future, by NATO, the United States, the United Kingdom, the European Union, Israel and its neighboring states and other countries have created global security concerns that could have a lasting impact on regional and global economies. Although the length and impact of the ongoing conflicts are highly unpredictable, they could lead to market disruptions, including significant volatility in commodity prices, credit and capital markets, as well as supply chain interruptions and increased cyberattacks against U.S. companies. Additionally, any resulting sanctions could adversely affect the global economy and financial markets and lead to instability and lack of liquidity in capital markets.

Any of the above mentioned factors, or any other negative impact on the global economy, capital markets or other geopolitical conditions resulting from the Russian invasion of Ukraine, the escalation of the Israel-Hamas conflict and subsequent sanctions or related actions, could adversely affect the Company’s search for an initial business combination and any target business with which the Company may ultimately consummate an initial business combination.

Registration Rights

The holders of the Founder Shares, Private Placement Warrants and warrants that may be issued upon conversion of Working Capital Loans (and any ordinary shares issuable upon the exercise of the Private Placement Warrants or warrants issued upon conversion of the Working Capital Loans and upon conversion of the Founder Shares) are entitled to registration rights pursuant to a registration rights agreement signed on the effective date of Initial Public Offering requiring the Company to register such securities for resale (in the case of the Founder Shares, only after conversion to Class A ordinary shares). The holders of these securities will be entitled to make up to three demands, excluding short form registration demands, that the Company register such securities. In addition, the holders have certain piggyback registration rights with respect to registration statements filed subsequent to completion of a Business Combination and rights to require the Company to register for resale such securities pursuant to Rule 415 under the Securities Act. However, the registration rights agreement provides that the Company will not be required to effect or permit any registration or cause any registration statement to become effective until the securities covered thereby are released from their lock-up restrictions. The Company will bear the expenses incurred in connection with the filing of any such registration statements.

Preference Shares — The Company is authorized to issue 1,500,000 preference shares with a par value of $0.0001 per share with such designations, voting and other rights and preferences as may be determined from time to time by the Company’s board of directors.

Class A Ordinary Shares — The Company is authorized to issue 150,000,000 Class A ordinary shares with a par value of $0.0001 per share. Holders of Class A ordinary shares are entitled to one vote for each share. As of June 30, 2024, there were no Class A ordinary shares issued or outstanding.

Class B Ordinary Shares — The Company is authorized to issue 15,000,000 Class B ordinary shares with a par value of $0.0001 per share. Holders of Class B ordinary shares are entitled to one vote for each share. As of June 30, 2024, there were 4,312,500 Class B ordinary shares issued and outstanding, of which an aggregate of up to 562,500 Class B ordinary shares are subject to forfeiture to the extent that the underwriters’ over-allotment option is not exercised in full or in part so that the number of Founder Shares will equal 20% of the Company’s issued and outstanding ordinary shares after the Initial Public Offering. On September 26, 2024, the underwriters partially exercised their over-allotment option and purchased an additional 300,000 Units. Due to the partial exercise and the decision to forfeit the remaining option, 487,500 Class B ordinary shares were forfeited and the Sponsor subsequently holds 3,825,000 Founder Shares.

Only holders of the Class B ordinary shares will have the right to vote on the election of directors prior to the Business Combination. Holders of Class A ordinary shares and holders of Class B ordinary shares will vote together as a single class on all matters submitted to a vote of the shareholder except as otherwise required by law. In connection with the initial business combination, the Company may enter into a shareholders’ agreement or other arrangements with the shareholders of the target or other investors to provide for voting or other corporate governance arrangements that differ from those in effect upon completion of this offering.

The Class B ordinary shares will convert into Class A ordinary shares concurrently with or immediately following the initial Business Combination, or earlier at the option of the holder, on a one-for-one basis, subject to adjustment for share subdivisions, share capitalizations, reorganizations, recapitalizations and the like, and subject to further adjustment as provided herein. In the case that additional Class A ordinary shares or equity-linked securities are issued or deemed issued in connection with the initial Business Combination, the number of Class A ordinary shares issuable upon conversion of all founder shares will equal, in the aggregate, 20% of the sum of (i) the total number of Class A ordinary shares issued and outstanding upon completion of the Initial Public Offering, plus (ii) the total number of Class A ordinary shares issuable upon conversion of the Class B ordinary shares issued and outstanding upon the completion of the Initial Public Offering, plus (iii) the total number of Class A ordinary shares issued, or deemed issued or issuable

NOTE 8. WARRANTS

There are no Public or Private Warrants outstanding as of June 30, 2024. Public Warrants may only be exercised for a whole number of shares. No fractional warrants will be issued upon separation of the Units and only whole warrants will trade. The Public Warrants will become exercisable on the later of (a) 30 days after the completion of a Business Combination and (b) 12 months from the closing of the Initial Public Offering. The Public Warrants will expire five years after the completion of a Business Combination or earlier upon redemption or liquidation.

The Company will not be obligated to deliver any Class A ordinary shares pursuant to the exercise of a warrant and will have no obligation to settle such warrant exercise unless a registration statement under the Securities Act covering the issuance of Class A ordinary shares issuable upon exercise of the warrants is then effective and a current prospectus relating to those Class A ordinary shares is available, subject to the Company satisfying its obligations with respect to registration, or a valid exemption from registration is available. No warrant will be exercisable for cash or on a cashless basis, and the Company will not be obligated to issue any shares to holders seeking to exercise their warrants, unless the issuance of the shares upon such exercise is registered or qualified under the securities laws of the state of residence of the exercising holder, or an exemption from registration is available.

The Company has agreed that as soon as practicable, but in no event later than 30 business days after the closing of a Business Combination, the Company will use its best efforts to file with the SEC, and will use its best efforts to have declared effective within 60 business days following the closing of its Business Combination, a registration statement covering the issuance of Class A ordinary shares issuable upon exercise of the warrants and to maintain a current prospectus relating to those Class A ordinary shares until the warrants expire or are redeemed. Notwithstanding the above, 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 it satisfies 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, the Company will not be required to file or maintain in effect a registration statement, but will use its best efforts to register or qualify the shares under applicable blue sky laws to the extent an exemption is not available.

Redemption of Warrants When the Price per Class A Ordinary Shares Equals or Exceeds $18.00 — Once the warrants become exercisable, the Company may redeem the outstanding Public Warrants:
