NOTE 1. DESCRIPTION OF ORGANIZATION AND BUSINESS OPERATIONS
SilverBox Corp IV (the “Company”) is a blank check company incorporated as a Cayman Islands exempted corporation on April 16, 2024. The Company was incorporated for the purpose of effecting a merger, amalgamation, share exchange, asset acquisition, share purchase, reorganization or similar business combination with one or more businesses (the “Business Combination”). The Company has not selected any specific Business Combination target and the Company has not, nor has anyone on its behalf, initiated any substantive discussions, directly or indirectly, with any Business Combination target.
As of September 30, 2025, the Company had not commenced any operations. All activity for the period from April 16, 2024 (inception) through September 30, 2025 relates to the Company’s formation and the initial public offering (“Initial Public Offering”), which is 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 interest income on investments from the proceeds derived from the Initial Public Offering.
The Company’s sponsor is SilverBox Sponsor IV LLC, a Delaware limited liability company (the “Sponsor”). The registration statement for the Company’s Initial Public Offering was declared effective on August 15, 2024. On August 19, 2024, the Company consummated the Initial Public Offering of
Simultaneously with the closing of the Initial Public Offering, the Company consummated the sale of an aggregate of

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.
The Company must complete one or more initial Business Combinations having an aggregate fair market value of at least

The Company will provide its public shareholders with the opportunity to redeem, regardless of whether they abstain, vote for, or vote against, the initial Business Combination, all or a portion of their Public Shares upon the completion of the initial Business Combination either (1) in connection with a shareholders’ meeting called to approve the Business Combination or (2) by means of a tender offer. The decision as to whether the Company will seek shareholder approval of a proposed Business Combination or conduct a tender offer will be made by the Company, solely in its discretion, and will be based on a variety of factors such as the timing of the transaction and whether the terms of the transaction would require the Company to seek shareholder approval under applicable law or stock exchange listing requirement. The shareholders will be entitled to redeem all or a portion of the Public Shares upon the completion of the initial Business Combination at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account as of two business days prior to the consummation of the initial Business Combination, including interest, divided by the number of the outstanding Public Shares, subject to the limitations described herein. The amount in the Trust Account was initially $
The ordinary shares subject to redemption will be recorded at a redemption value and classified as temporary equity upon the completion of the Initial Public Offering, in accordance with Accounting Standards Codification (“ASC”) Topic 480, “Distinguishing Liabilities from Equity.” In such case, the Company will proceed with a Business Combination if the Company has net tangible assets, after payment of the deferred underwriting commissions, of at least $
The Company will have only
The Sponsor, directors and officers have entered into a letter agreement with the Company, pursuant to which they have agreed to (1) waive their redemption rights with respect to any Founder Shares (as defined in Note 4) and any Public Shares held by them in connection with the completion of the initial Business Combination; (2) waive their redemption rights with respect to any Founder Shares and Public Shares held by them in connection with a shareholder vote to approve an amendment to the Company’s amended and restated memorandum and articles of association (A) to modify the substance or timing of the Company’s obligation to provide for the redemption of the Company’s Public Shares in connection with the initial Business Combination or to redeem

The Sponsor has agreed that it will be liable to the Company if and to the extent any claims by a third party (other than 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 entered into a written letter of intent, confidentiality or similar agreement or Business Combination agreement, reduce the amount of funds in the Trust Account to below (1) $

In connection with the Company’s assessment of going concern considerations in accordance with ASC 205-40, “Going Concern,” as of September 30, 2025, the Company may need to raise additional capital through loans or additional investments from its Sponsor, shareholders, officers, directors, or third parties. The Company’s officers, directors and Sponsor may, but are not obligated to, loan the Company funds, from time to time or at any time, in whatever amount they deem reasonable in their sole discretion, to meet the Company’s working capital needs. 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, curtailing operations, suspending the pursuit of a potential transaction, and reducing overhead expenses. The Company cannot provide any assurance that new financing will be available to it on commercially acceptable terms, if at all.

Additionally, if a Business Combination is not consummated by the end of the Combination Period, currently August 19, 2026, there will be a mandatory liquidation and subsequent dissolution of the Company. No adjustments have been made to the carrying amounts of assets or liabilities should the Company be required to liquidate after the Combination Period. The Company’s liquidity condition and mandatory liquidation within one year of the issuance of these unaudited condensed financial statements raise substantial doubt about the Company’s ability to continue as a going concern. Management plans to address this uncertainty through a Business Combination. However, there can be no assurance that the Company will be able to consummate any Business Combination by the end of the Combination Period.
The Company’s liquidity condition and mandatory liquidation within one year raises substantial doubt about the Company’s ability to continue as a going concern for a period of time within one year after the date that the accompanying condensed financial statements are issued. Management plans to address this uncertainty through a Business Combination. No adjustments have been made to the carrying amounts of assets or liabilities should the Company be required to liquidate after the Combination Period. The Company intends to complete the initial Business Combination before the end of the Combination Period. However, there can be no assurance that the Company will be able to consummate any Business Combination by the end of the Combination Period.
NOTE 2. SIGNIFICANT ACCOUNTING POLICIES
Basis of Presentation
The accompanying unaudited condensed financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial information and in accordance with the instructions to Form 10-Q and Article 8 of Regulation S-X of the U.S. Securities and Exchange Commission (“SEC”). Certain information or footnote disclosures normally included in financial statements prepared in accordance with GAAP have been condensed or omitted, pursuant to the rules and regulations of the SEC for interim financial reporting. Accordingly, they do not include all the information and footnotes necessary for a complete presentation of financial position, results of operations, or cash flows. In the opinion of management, the accompanying unaudited condensed financial statements include all adjustments, consisting of a normal recurring nature, which are necessary for a fair presentation of the financial position, operating results and cash flows for the periods presented.
The accompanying unaudited condensed financial statements should be read in conjunction with the Company’s Annual Report on Form 10-K as filed with the SEC on March 13, 2025. The interim results for the three and nine months ended September 30, 2025, are not necessarily indicative of the results to be expected for the year ending December 31, 2025 or for any future periods.
Emerging Growth Company
The Company is an “emerging growth company,” as defined in Section 2(a) of the Securities Act of 1933, as amended (the “Securities Act”), as modified by the Jumpstart Our Business Startup Act of 2012 (the “JOBS Act”), and it may take advantage of certain exemptions from various reporting requirements that are applicable to other public companies that are not emerging growth companies including, but not limited to, not being required to comply with the auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act of 2002, reduced disclosure obligations regarding executive compensation in its periodic reports and proxy statements and exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and shareholder approval of any golden parachute payments not previously approved.
Further, Section 102(b)(1) of the JOBS Act exempts emerging growth companies from being required to comply with new or revised financial accounting standards until private companies (that is, those that have not had a Securities Act registration statement declared effective or do not have a class of securities registered under the Exchange Act) are required to comply with the new or revised financial accounting standards. The JOBS Act provides that an emerging growth company can elect to opt out of the extended transition period and comply with the requirements that apply to non-emerging growth companies, but any such election to opt out is irrevocable. The Company has elected not to opt out of such extended transition period which means that when a standard is issued or revised and it has different application dates for public or private companies, the Company, as an emerging growth company, can adopt the new or revised standard at the time private companies adopt the new or revised standard. This may make comparison of the Company’s financial statements with another public company which is neither an emerging growth company nor an emerging growth company which has opted out of using the extended transition period difficult or impossible because of the potential differences in accounting standards used.

Use of Estimates
The preparation of the condensed financial statements in conformity with GAAP requires the Company’s management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the condensed financial statements and the reported amounts of revenues and expenses during the reporting period.
Making estimates requires management to exercise significant judgment. It is at least reasonably possible that the estimate of the effect of a condition, situation or set of circumstances that existed at the date of the condensed financial statements, which management considered in formulating its estimate, could change in the near term due to one or more future confirming events. Accordingly, the actual results could differ significantly from those estimates.
Cash and Cash Equivalents
The Company considers all short-term investments with an original maturity of three months or less when purchased to be cash equivalents. The Company had $
Investments Held in Trust Account
As of September 30, 2025 and December 31, 2024, substantially all of the assets held in the Trust Account were held in U.S. Treasury Bills. The Company’s investments are presented at fair value on the condensed balance sheets. Gains and losses resulting from the change in fair value of marketable securities held in the Trust Account are included in interest earned on investments held in Trust Account in the condensed statements of operations. As of September 30, 2025 and December 31, 2024, the Company did not withdraw any interest earned on the Trust Account.
Fair Value of Financial Instruments
The fair value of the Company’s assets and liabilities, which qualify as financial instruments under Financial Accounting Standards Board (“FASB”) ASC 820, “Fair Value Measurements and Disclosures,” approximates the carrying amounts represented in the condensed balance sheets, primarily due to its short-term nature.
Derivative Financial Instruments
The Company evaluates its financial instruments to determine if such instruments are derivatives or contain features that qualify as embedded derivatives in accordance with ASC Topic 815, “Derivatives and Hedging”. For derivative financial instruments that are accounted for as liabilities, the derivative instrument is initially recorded at its fair value on the grant date and is then re-valued at each reporting date, with changes in the fair value reported in the condensed statements of operations. The classification of derivative instruments, including whether such instruments should be recorded as liabilities or as equity, is evaluated at the end of each reporting period. Derivative liabilities are classified in the condensed balance sheets as current or non-current based on whether or not net cash settlement or conversion of the instrument could be required within 12 months of the condensed balance sheet date. The underwriters’ over-allotment option was deemed to be a freestanding financial instrument indexed on the contingently redeemable shares and was accounted for as a liability pursuant to ASC 480 since the option was not exercised at the Initial Public Offering. However, the underwriters elected not to exercise the over-allotment option and the option expired, effective September 30, 2024, and the over-allotment option liability was derecognized.

Fair Value Measurement
Fair value is defined as the price that would be received for sale of an asset or paid for transfer of a liability in an orderly transaction between market participants at the measurement date. GAAP establishes a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). These tiers include:
| ● | Level 1, defined as observable inputs such as quoted prices (unadjusted) for identical instruments in active markets; |
| ● | Level 2, defined as inputs other than quoted prices in active markets that are either directly or indirectly observable such as quoted prices for similar instruments in active markets or quoted prices for identical or similar instruments in markets that are not active; and |
| ● | Level 3, defined as unobservable inputs in which little or no market data exists, therefore requiring an entity to develop its own assumptions, such as valuations derived from valuation techniques in which one or more significant inputs or significant value drivers are unobservable. |
In some circumstances, the inputs used to measure fair value might be categorized within different levels of the fair value hierarchy. In those instances, the fair value measurement is categorized in its entirety in the fair value hierarchy based on the lowest level input that is significant to the fair value measurement.
Concentration of Credit Risk
Financial instruments that potentially subject the Company to concentrations of credit risk consist of a cash account in a financial institution, which, at times, may exceed the Federal Deposit Insurance Corporation coverage limit of $250,000. Any loss incurred or a lack of access to such funds could have a significant adverse impact on the Company’s financial condition, results of operations, and cash flows.
Offering Costs
The Company complies with the requirements of the ASC 340-10-S99 and SEC Staff Accounting Bulletin Topic 5A, “Expenses of Offering.” Deferred offering costs consist principally of professional and registration fees that are related to the Initial Public Offering. FASB ASC 470-20, “Debt with Conversion and Other Options,” addresses the allocation of proceeds from the issuance of convertible debt into its equity and debt components. The Company applies this guidance to allocate Initial Public Offering proceeds from the Units between Class A ordinary shares and warrants, using the residual method by allocating Initial Public Offering proceeds first to assigned value of the warrants and then to the Class A ordinary shares. Offering costs allocated to the Public Shares were charged to temporary equity, and offering costs allocated to the Public and Private Placement Warrants were charged to shareholders’ deficit as Public and Private Placement Warrants and after management’s evaluation they were accounted for under equity treatment.
Income Taxes
The Company accounts for income taxes under ASC 740, “Income Taxes’’ (“ASC 740”). ASC 740 requires the recognition of deferred tax assets and liabilities for both the expected impact of differences between the financial statement and tax basis of assets and liabilities and for the expected future tax benefit to be derived from tax loss and tax credit carryforwards. ASC 740 additionally requires a valuation allowance to be established when it is more likely than not that all or a portion of deferred tax assets will not be realized.
ASC 740 prescribes a recognition threshold and a measurement attribute for the financial statement recognition and measurement of tax positions taken or expected to be taken in a tax return. For those benefits to be recognized, a tax position must be more likely than not to be sustained upon examination by taxing authorities. The Company’s management determined that the Cayman Islands is the Company’s major tax jurisdiction. The Company recognizes accrued interest and penalties related to unrecognized tax benefits as income tax expense. As of September 30, 2025 and December 31, 2024, there were

The Company is considered to be an exempted Cayman Islands company with no connection to any other taxable jurisdiction and is presently not subject to income taxes or income tax filing requirements in the Cayman Islands or the United States. As such, the Company’s tax provision was
Class A Ordinary Shares Subject to Possible Redemption
The public shares contain a redemption feature which allows for the redemption of such public shares in connection with the Company’s liquidation, or if there is a shareholder vote or tender offer in connection with the Company’s initial Business Combination. In accordance with ASC 480-10-S99, the Company classifies public shares subject to possible redemption outside of permanent deficit as the redemption provisions are not solely within the control of the Company. The Company recognizes changes in redemption value immediately as they occur and will adjust the carrying value of redeemable shares to equal the redemption value at the end of each reporting period. Immediately upon the closing of the Initial Public Offering, the Company recognized the accretion from initial book value to redemption amount value. The change in the carrying value of redeemable shares will result in charges against additional paid-in capital (to the extent available) and accumulated deficit. Accordingly, at September 30, 2025 and December 31, 2024, Class A ordinary shares subject to possible redemption are presented at redemption value as temporary equity, outside of the shareholders’ deficit section of the Company’s condensed balance sheets. As of September 30, 2025 and December 31, 2024, the Class A ordinary shares subject to possible redemption reflected in the condensed balance sheets are reconciled in the following table:

Warrant Instruments
The Company accounts for warrants as either equity-classified or liability-classified instruments based on an assessment of the warrant’s specific terms and applicable authoritative guidance in FASB ASC 480, “Distinguishing Liabilities from Equity” (“ASC 480”), and ASC 815, “Derivatives and Hedging” (“ASC 815”). The assessment considers whether the warrants are freestanding financial instruments pursuant to ASC 480, meet the definition of a liability pursuant to ASC 480, and whether the warrants meet all of the requirements for equity classification under ASC 815, including whether the warrants are indexed to the Company’s own ordinary shares and whether the warrant holders could potentially require “net cash settlement” in a circumstance outside of the Company’s control, among other conditions for equity classification. This assessment, which requires the use of professional judgment, is conducted at the time of warrant issuance and as of each subsequent quarterly period end date while the warrants are outstanding.
For issued or modified warrants that meet all of the criteria for equity classification, the warrants are required to be recorded as a component of additional paid-in capital at the time of issuance. For issued or modified warrants that do not meet all the criteria for equity classification, the warrants are required to be recorded at their initial fair value on the date of issuance, and each balance sheet date thereafter. Accordingly, the Company evaluated and classified the warrant instruments under equity treatment at its assigned fair value.

Net Income per Ordinary Share
The Company complies with accounting and disclosure requirements of FASB ASC Topic 260, “Earnings Per Share”. Net income per ordinary share is computed by dividing net income by the weighted average number of ordinary shares outstanding for the period. This presentation contemplates a Business Combination as the most likely outcome, in which case, both classes of shares share pro rata in the net income of the Company. Accretion associated with the redeemable shares of Class A ordinary shares is excluded from earnings per share as the redemption value approximates fair value.
The calculation of diluted net income per ordinary share does not consider the effect of the warrants issued in connection with the (i) IPO, and (ii) the private placement since the exercise of the warrants is contingent upon the occurrence of future events. The warrants are exercisable to purchase
The following table reflects the calculation of basic and diluted net income per ordinary share:

Recent Accounting Pronouncements
In November 2024, the FASB issued Accounting Standards Update (“ASU”) 2024-03, “Income Statement-Reporting Comprehensive Income-Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses”, requiring public entities to disclose additional information about specific expense categories in the notes to the financial statements on an interim and annual basis. ASU 2024-03 is effective for fiscal years beginning after December 15, 2026, and for interim periods beginning after December 15, 2027, with early adoption permitted. The Company is currently evaluating the impact of adopting ASU 2024-03.
Management does not believe that any other recently issued, but not yet effective, accounting pronouncements, if currently adopted, would have a material effect on the Company’s condensed financial statements.

NOTE 5. COMMITMENTS AND CONTINGENCIES
Risks and Uncertainties
The United States and global markets are experiencing volatility and disruption following the geopolitical instability resulting from each of the ongoing Russia-Ukraine and Israel-Hamas conflicts, as well as recent developments to U.S. tariff policies. 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 Israel-Hamas conflict and subsequent sanctions or related actions or the ongoing trade and tariff policy changes by the United States or other countries, 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.

ASC Topic 280, “Segment Reporting,” establishes standards for companies to report in their financial statement information about operating segments, products, services, geographic areas, and major customers. Operating segments are defined as components of an enterprise for which separate financial information is available that is regularly evaluated by the Company’s chief operating decision maker (“CODM”), or group, in deciding how to allocate resources and assess performance.
The Company’s CODM has been identified as the Chief Executive Officer, who reviews the operating results for the Company as a whole to make decisions about allocating resources and assessing financial performance. Accordingly, management has determined that the Company only has
The CODM assesses performance for the single segment and decides how to allocate resources based on net income or loss that also is reported on the condensed statements of operations as net income or loss. The measure of segment assets is reported on the condensed balance sheets as total assets. When evaluating the Company’s performance and making key decisions regarding resource allocation, the CODM reviews several key metrics, included in net income or loss and total assets, which include the following:

The CODM reviews interest earned on the Trust Account to measure and monitor shareholder value and determine the most effective strategy of investment with the Trust Account funds while maintaining compliance with the trust agreement. General and administrative expenses are reviewed and monitored by the CODM to manage and forecast cash to ensure enough capital is available to complete a Business Combination within the Business Combination period. The CODM also reviews general and administrative costs to manage, maintain and enforce all contractual agreements to ensure costs are aligned with all agreements and budget. General and administrative expenses, as reported on the condensed statements of operations, are the significant segment expenses provided to the CODM on a regular basis. All other segment items included in net income or loss are reported on the condensed statements of operations and described within their respective disclosures.

Overview
We are a blank check company incorporated in the Cayman Islands on April 16, 2024 for the purpose of effecting a merger, amalgamation, share exchange, asset acquisition, share purchase, reorganization or other similar Business Combination with one or more businesses. We intend to effectuate our Business Combination using cash derived from the proceeds of the Initial Public Offering and the sale of the Private Placement Units, our shares, debt or a combination of cash, shares and debt.
We expect to continue to incur significant costs in the pursuit of our acquisition plans. We cannot assure you that our plans to complete a Business Combination will be successful.
Recent Developments
On August 6, 2025, the Company, Parataxis Holdings Inc., a Delaware corporation (“Pubco”), PTX Merger Sub I Inc., a Delaware corporation and a wholly-owned subsidiary of Pubco (“SPAC Merger Sub”), PTX Merger Sub II LLC, a Delaware limited liability company and a wholly-owned subsidiary of Pubco (“Parataxis Merger Sub”), Parataxis Holdings LLC, a Delaware limited liability company (“Parataxis”), the Sponsor, solely for certain limited purposes as representative of the Company shareholders, and Edward Chin, solely for certain limited purposes as representative of the members of Parataxis, entered into a business combination agreement (the “Business Combination Agreement”).
Pursuant to the Business Combination Agreement, and subject to the terms and conditions set forth therein, (a) SPAC Merger Sub will merge with and into the Company, with the Company continuing as the surviving company (the “SPAC Merger”), and with each Company shareholder receiving one share of Pubco Class A common stock (“Pubco Class A Stock”) for each SPAC Class A Ordinary Share held by such shareholder in accordance with the terms of the Business Combination Agreement and (b) Parataxis Merger Sub will merge with and into Parataxis, with Parataxis continuing as the surviving entity (the “Parataxis Merger”, and together with the SPAC Merger, the “Mergers”), and with members of Parataxis receiving shares of Pubco Class A Stock (other than certain members of Parataxis who will receive shares of Pubco Class C common stock (“Pubco Class C Stock”)) in exchange for their units in Parataxis in accordance with the terms of the Business Combination Agreement. As a result of the Mergers, SPAC and Parataxis will become wholly owned subsidiaries of Pubco, and Pubco will become a publicly traded company, all upon the terms and subject to the conditions set forth in the Business Combination Agreement and in accordance with applicable law. Prior to the SPAC Merger, the Company will de-register from the Register of Companies in the Cayman Islands by way of continuation out of the Cayman Islands and into the State of Delaware so as to re-domicile as and become a Delaware corporation.

Results of Operations
We have neither engaged in any operations nor generated any revenues to date. Our only activities from April 16, 2024 (inception) through September 30, 2025 were organizational activities and those activities necessary to prepare for the Initial Public Offering, described below. We do not expect to generate any operating revenues until after the completion of our Business Combination. Subsequent to the Initial Public Offering, we generate non-operating income in the form of interest income on investments held in the Trust Account. We incur expenses as a result of being a public company (for legal, financial reporting, accounting and auditing compliance), as well as for due diligence expenses.
For the three months ended September 30, 2025, we had a net income $637,702, which consisted of interest earned on investments held in Trust Account of $2,255,300, offset by general and administrative costs of $1,564,598 and Compensation Expense $53,000.
For the nine months ended September 30, 2025, we had a net income $4,031,086, which consisted of interest earned on investments held in Trust Account of $6,553,627, offset by general and administrative costs of $2,469,541 and Compensation Expense $53,000.
For the three months ended September 30, 2024, we had a net income $1,382,148, which consisted of change in fair value of over-allotment option liability of $306,504 and interest earned on investments held in Trust Account of $1,266,313, offset by general and administrative costs of $190,669.
For the period from April 16, 2024 (inception) through September 30, 2024, we had a net income $1,358,488, which consisted of change in fair value of over-allotment option liability of $306,504 and interest earned on investments held in Trust Account of $1,266,313, offset by general and administrative costs of $214,329.
Liquidity, Capital Resources and Going Concern
On August 19, 2024, we consummated the Initial Public Offering of 20,000,000 Units at $10.00 per Units. Simultaneously with the closing of the Initial Public Offering, we consummated the sale of an aggregate of 455,000 Private Placement Units at a price of $10.00 per Private Placement Unit, in a private placement to the Sponsor, generating gross proceeds of $4,550,000.
For the nine months ended September 30, 2025, cash used in operating activities was $853,693. Net income of $4,031,086 was affected by interest earned on investments held in the Trust Account of $6,553,627 and compensation expense of $53,000. Changes in operating assets and liabilities used $1,615,848 of cash for operating activities.
For the period from April 16, 2024 (inception) through September 30, 2024, cash used in operating activities was $314,085. Net income of $1,358,488 was affected by interest earned on investments held in the Trust Account of $1,266,313, formation costs paid by Sponsor in exchange for issuance of Class B ordinary shares of $15,524 and change in fair value of over-allotment option liability of $306,504. Changes in operating assets and liabilities used $115,280 of cash for operating activities.
As of September 30, 2025, we had investments held in the Trust Account of $211,208,265 (including approximately $10,208,265 of interest income) consisting of U.S. Treasury Bills with a maturity of 185 days or less. We may withdraw interest from the Trust Account to pay taxes, if any. We intend to use substantially all of the funds held in the Trust Account, including any amounts representing interest earned on the Trust Account (less income taxes payable), to complete our Business Combination. To the extent that our share capital or debt is used, in whole or in part, as consideration to complete our Business Combination, the remaining proceeds held in the Trust Account will be used as working capital to finance the operations of the target business or businesses, make other acquisitions and pursue our growth strategies.
As of September 30, 2025, we had cash of $55,669. We intend to use the funds held outside the Trust Account primarily to identify and evaluate target businesses, perform business due diligence on prospective target businesses, travel to and from the offices, plants or similar locations of prospective target businesses or their representatives or owners, review corporate documents and material agreements of prospective target businesses, and structure, negotiate and complete a Business Combination.
In order to fund working capital deficiencies or finance transaction costs in connection with a Business Combination, the Sponsor, or certain of our officers and directors or their affiliates may, but are not obligated to, loan us funds as may be required. If we complete a Business Combination, we would repay such loaned amounts. In the event that a Business Combination does not close, we may use a portion of the working capital held outside the Trust Account to repay such loaned amounts but no proceeds from our Trust Account would be used for such repayment. Up to $2,500,000 of such loans (the “Working Capital Loans”) may be convertible into units of the
21
post-Business Combination entity at a price of $10.00 per unit. The units and the underlying securities would be identical to the Private Placement Units and the underlying securities of such Private Placement Units.
In connection with the Company’s assessment of going concern considerations in accordance with ASC 205-40, “Going Concern,” as of September 30, 2025, the Company may need to raise additional capital through loans or additional investments from its Sponsor, shareholders, officers, directors, or third parties. The Company’s officers, directors and Sponsor may, but are not obligated to, loan the Company funds, from time to time or at any time, in whatever amount they deem reasonable in their sole discretion, to meet the Company’s working capital needs. 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, curtailing operations, suspending the pursuit of a potential transaction, and reducing overhead expenses. The Company cannot provide any assurance that new financing will be available to it on commercially acceptable terms, if at all.
Additionally, if a Business Combination is not consummated by the end of the Combination Period, currently August 19, 2026, there will be a mandatory liquidation and subsequent dissolution of the Company. No adjustments have been made to the carrying amounts of assets or liabilities should the Company be required to liquidate after the Combination Period. The Company’s liquidity condition and mandatory liquidation within one year of the issuance of these unaudited condensed financial statements raise substantial doubt about the Company’s ability to continue as a going concern. Management plans to address this uncertainty through a Business Combination. However, there can be no assurance that the Company will be able to consummate any Business Combination by the end of the Combination Period.
The Company’s liquidity condition and mandatory liquidation within one year raises substantial doubt about the Company’s ability to continue as a going concern for a period of time within one year after the date that the accompanying condensed financial statements are issued. Management plans to address this uncertainty through a Business Combination. No adjustments have been made to the carrying amounts of assets or liabilities should the Company be required to liquidate after the Combination Period. The Company intends to complete the initial Business Combination before the end of the Combination Period. However, there can be no assurance that the Company will be able to consummate any Business Combination by the end of the Combination Period.
Off-Balance Sheet Arrangements
We have no obligations, assets or liabilities, which would be considered off-balance sheet arrangements as of September 30, 2025. We do not participate in transactions that create relationships with unconsolidated entities or financial partnerships, often referred to as variable interest entities, which would have been established for the purpose of facilitating off-balance sheet arrangements. We have not entered into any off-balance sheet financing arrangements, established any special purpose entities, guaranteed any debt or commitments of other entities, or purchased any non-financial assets.
Contractual Obligations
We do not have any long-term debt, capital lease obligations, operating lease obligations or long-term liabilities, other than an agreement to pay the Sponsor a total of $15,000 per month for office space, secretarial, administrative and shared personnel support services.
The underwriters were entitled to a cash underwriting discount of $1,700,000 or 0.85% of the gross proceeds of the units sold in the Initial Public Offering, which was paid on August 19, 2024. Additionally, the underwriters are entitled to a deferred underwriting discount of 5.15% of the gross proceeds of the Initial Public Offering held in the Trust Account, $10,300,000 in the aggregate upon the completion of the Company’s initial Business Combination subject to the terms of the underwriting agreement.
On August 6, 2025, the Company engaged Santander US Capital Markets LLC (“Santander”) to act as the Company’s equity capital markets advisor with respects to the transaction between the Company and Parataxis. Subject to the closing of the transaction between the Company and Parataxis (the “transaction”), Santander will be entitled to a transaction fee in the amount of $10,300,000 and will be in lieu of the deferred underwriting fee. Additionally, Santander may seek reimbursements up to $75,000, which are payable at the completion or termination of the transaction.

Critical Accounting Policies and Estimates
The preparation of the financial statements and related disclosures in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements, and income and expenses during the periods reported. Actual results could materially differ from those estimates. The Company has not identified any critical accounting estimates but have identified the following critical accounting policies:

We account for our ordinary shares subject to possible conversion in accordance with the guidance in Accounting Standards Codification (“ASC”) Topic 480, “Distinguishing Liabilities from Equity.” Ordinary shares subject to mandatory redemption are classified as a liability instrument and measured at fair value. Conditionally redeemable ordinary shares (including ordinary shares that feature redemption rights that are either within the control of the holder or subject to redemption upon the occurrence of uncertain events not solely within our control) are classified as temporary equity. At all other times, ordinary shares are classified as shareholders’ deficit. Our ordinary shares feature certain redemption rights that are considered to be outside of our control and subject to occurrence of uncertain future events. Accordingly, as of September 30, 2025, ordinary shares subject to possible redemption are presented at redemption value as temporary equity, outside of the shareholders’ deficit section of our balance sheets.
The Company recognizes changes in redemption value immediately as they occur and adjusts the carrying value of redeemable ordinary shares to equal the redemption value at the end of each reporting period. Increases or decreases in the carrying amount of the redeemable ordinary shares are affected by charges against additional paid-in capital (to the extent available) and accumulated deficit.
Warrant Instruments
We account for warrants as either equity-classified or liability-classified instruments based on an assessment of the warrant’s specific terms and applicable authoritative guidance in FASB ASC 480, “Distinguishing Liabilities from Equity” (“ASC 480”), and ASC 815, “Derivatives and Hedging” (“ASC 815”). The assessment considers whether the warrants are freestanding financial instruments pursuant to ASC 480, meet the definition of a liability pursuant to ASC 480, and whether the warrants meet all of the requirements for equity classification under ASC 815, including whether the warrants are indexed to the Company’s own ordinary shares and whether the warrant holders could potentially require “net cash settlement” in a circumstance outside of the Company’s control, among other conditions for equity classification. This assessment, which requires the use of professional judgment, is conducted at the time of warrant issuance and as of each subsequent quarterly period end date while the warrants are outstanding.
For issued or modified warrants that meet all of the criteria for equity classification, the warrants are required to be recorded as a component of additional paid-in capital at the time of issuance. For issued or modified warrants that do not meet all the criteria for equity classification, the warrants are required to be recorded at their initial fair value on the date of issuance, and each balance sheet date thereafter. Accordingly, the Company evaluated and classified the warrant instruments under equity treatment at its assigned fair value. Fair value of public warrants at issuance amounted to $286,667.
Recent Accounting Standards
In November 2024, the FASB issued Accounting Standards Update (“ASU”) 2024-03, “Income Statement-Reporting Comprehensive Income-Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses”, requiring public entities to disclose additional information about specific expense categories in the notes to the financial statements on an interim and annual basis. ASU 2024-03 is effective for fiscal years beginning after December 15, 2026, and for interim periods beginning after December 15, 2027, with early adoption permitted. The Company is currently evaluating the impact of adopting ASU 2024-03.
Management does not believe that any other recently issued, but not yet effective, accounting pronouncements, if currently adopted, would have a material effect on the Company’s condensed financial statements.
Item 3. Quantitative and Qualitative Disclosures About Market Risk
Not required for smaller reporting companies.

Item 4. Controls and Procedures
Evaluation of Disclosure Controls and Procedures
Disclosure controls and procedures are controls and other procedures designed to ensure that information required to be disclosed in our reports filed or submitted under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed in our reports filed or submitted under the Exchange Act is accumulated and communicated to Management, including our Chief Executive Officer and Chief Financial Officer (together, the “Certifying Officers”), or persons performing similar functions, as appropriate, to allow timely decisions regarding required disclosure.
Under the supervision and with the participation of our Management, including our Certifying Officers, we carried out an evaluation of the effectiveness of the design and operation of our disclosure controls and procedures as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act. Based on the foregoing, our Certifying Officers concluded that our disclosure controls and procedures were effective as of the end of the quarterly period ended September 30, 2025.
Changes in Internal Control over Financial Reporting
There was no change in our internal control over financial reporting that occurred during the fiscal quarter of 2025 covered by this Quarterly Report on Form 10-Q that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.
