REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Shareholders of
SilverBox Corp V:

Opinion on the Financial Statement

We have audited the accompanying balance sheet of SilverBox Corp. V (the “Company”) as of December 4, 2025, and the related notes (collectively referred to as the “financial statement”). In our opinion, the financial statement presents fairly, in all material respects, the financial position of the Company as of December 4, 2025, in conformity with accounting principles generally accepted in the United States of America.

Basis for Opinion

The financial statement is the responsibility of the Company's management. Our responsibility is to express an opinion on the Company's financial statement based on our audit. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (the "PCAOB") and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statement is free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audit, we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial reporting. Accordingly, we express no such opinion.

Our audit included performing procedures to assess the risks of material misstatement of the financial statement, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statement. Our audit also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statement. We believe that our audit provides a reasonable basis for our opinion.

/s/ WithumSmith+Brown, PC

We have served as the Company's auditor since 2025.

NOTES TO FINANCIAL STATEMENT
DECEMBER 4, 2025

Note 1 — Organization and Business Operation

SilverBox Corp V (the “Company”) is a blank check company incorporated as a Cayman Islands exempted company on May 29, 2025. The Company was incorporated for the purpose of effecting a merger, share exchange, asset acquisition, share purchase, reorganization or similar business combination with one or more businesses (the “Business Combination”). The Company 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 December 4, 2025, the Company had not commenced any operations. All activity for the period from May 29, 2025 (inception) through December 4, 2025 relates to the Company’s formation and the initial public offering 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 nonoperating income in the form of interest income on cash and cash equivalents from the proceeds derived from the Initial Public Offering (as defined below).

The Company’s sponsor is SilverBox Sponsor V LLC, a Delaware limited liability company (the “Sponsor”). The registration statement for the Company’s Initial Public Offering was declared effective on December 2, 2025. On December 4, 2025, the Company consummated the Initial Public Offering of 27,600,000 units at $10.00 per unit (the “Units”), which is discussed in Note 3 (the “Initial Public Offering”), which includes the full exercise of the underwriters’ over-allotment option of 3,600,000 Units, generating gross proceeds of $276,000,000. Simultaneously with the closing of the Initial Public Offering, the Company consummated the sale of 195,000 units (the “Private Placement Units”) to the Sponsor, at a price of $10.00 per Private Placement Unit, or $1,950,000 in the aggregate.

Transaction costs amounted to $9,240,771, consisting of $225,000 of cash underwriting fee (net of $25,000 underwriters’ reimbursement), $8,280,000 of deferred underwriting fee, and $735,771 of other offering costs.

The Company must complete one or more initial Business Combinations having an aggregate fair market value of at least 80% of the value of the Trust Account (as defined below) (excluding any deferred underwriting commissions and taxes payable on the interest earned on the Trust Account) at the time of the signing a definitive agreement in connection with the initial Business Combination. However, the Company will only complete a Business Combination if the post-transaction company owns or acquires 50% or more of the outstanding voting securities of the target or otherwise acquires a controlling interest in the target business sufficient for it not to be required to register as an investment company under the Investment Company Act 1940, as amended (the “Investment Company Act”). There is no assurance that the Company will be able to complete a Business Combination successfully.

Upon the closing of the Initial Public Offering on December 4, 2025, an amount of $276,000,000 ($10.00 per Unit) from the net proceeds of the sale of the Units, and a portion of the proceeds from the sale of the Private Placement Units, was placed in a trust account (the “Trust Account”) and will be (i) invested only in U.S. government securities, within the meaning set forth in Section 2(a)(16) of 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 or (ii) deposited in an interest bearing demand deposit account at a U.S.- chartered commercial bank with consolidated assets of $100 billion or more. Except with respect to interest earned on the funds held in the Trust Account that may be released to the Company as described below, the funds held in the Trust Account will not be released from the Trust Account until the earliest to occur of (1) the Company’s completion of an initial Business Combination; (2) the redemption of any Public Shares properly submitted in connection with a shareholder vote to amend 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 100% of the Public Shares if the Company does not consummated the initial Business Combination within the Completion

Window (as defined below) from the closing of the Initial Public Offering or (B) with respect to any other provision relating to shareholders’ rights or pre-initial Business Combination activity; and (3) the redemption of all of the Company’s Public Shares if the Company has not completed an initial Business Combination within the Completion Window, subject to applicable law. The proceeds deposited in the Trust Account could become subject to the claims of the creditors, if any, which could have priority over the claims of the Company’s public shareholders.

The Company will provide its public shareholders with the opportunity to redeem, regardless of whether they abstain, vote for, or vote against, its 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 shareholder 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 is initially anticipated to be $10.00 per Public Share.

The ordinary shares subject to redemption are 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 seeks shareholder approval and a majority of the issued and outstanding shares voted are voted in favor of the Business Combination.

The Company will have only 24 months from the closing of the Initial Public Offering to complete the initial Business Combination (the “Completion Window”). However, if the Company has not completed the initial Business Combination within the Completion Window or the Company does not otherwise seek shareholder approval to amend the amended and restated memorandum and articles of association to further extend the time to complete the initial Business Combination, the Company will (1) cease all operations except for the purpose of winding up; (2) as promptly as reasonably possible but no more than ten business days thereafter, subject to lawfully available funds therefor, 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, divided by the number of the outstanding Public Shares, which redemption will completely extinguish public shareholders’ rights as shareholders (including the right to receive further liquidating distributions, if any); and (3) as promptly as reasonably possible following such redemption, subject to the approval of the Company’s remaining shareholders and the Company’s board of directors, dissolve and liquidate, subject in each case to the Company’s obligations under Cayman Islands law to provide for claims of creditors and the requirements of other applicable law.

The Sponsor, directors and officers entered into a letter agreement with the Company, pursuant to which they 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 100% of the Public Shares if the Company does not consummated its initial Business Combination within the Completion Window or (B) with respect to any other provision relating to shareholders’ rights or pre-initial Business Combination activity; and (3) waive their rights to liquidating distributions from the Trust Account with respect to any Founder Shares and private placement shares they hold if the Company fails to complete its initial Business Combination within the Completion Window (although they will be entitled to liquidating distributions from the Trust Account with respect to any Public Shares they hold if the Company fails to complete the initial Business Combination within the Completion Window); and (4) vote their Founder Shares and any Public Shares purchased during or after the Initial Public Offering (including in open market and privately negotiated transactions) in favor of the initial Business Combination (except that any Public Shares such parties may purchase in compliance with the requirements of Rule 14e-5 under the Securities Exchange Act of 1934 would not be voted in favor of approving the Business Combination transaction.

Note 1 — Organization and Business Operation (cont.)

The Sponsor 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) $10.00 per Public Share or (2) the actual amount per share held in the Trust Account as of the date of the liquidation of the Trust Account if less than $10.00 per share due to reductions in the value of the trust assets, less taxes payable, provided that such liability will not apply to any claims by a third party or prospective target business who executed a waiver of any and all rights to the monies held in the Trust Account (whether or not such waiver is enforceable) nor will it apply to any claims under the Company’s indemnity of the underwriters of the Initial Public Offering against certain liabilities, including liabilities under the Securities Act (as defined in Note 2). However, the Company has not asked the Sponsor to reserve for such indemnification obligations, nor has the Company independently verified whether the Sponsor has sufficient funds to satisfy its indemnity obligations and the Company believes that the Sponsor’s only assets are securities of the Company. Therefore, the Company cannot assure that the Sponsor would be able to satisfy those obligations. None of the Company’s officers or directors will indemnify the Company for claims by third parties including, without limitation, claims by vendors and prospective target businesses.

Note 2 — Significant Accounting Policies

Basis of Presentation

The accompanying financial statement is presented in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”) and pursuant to the rules and regulations of the U.S. Securities and Exchange Commission (“SEC”).

Liquidity

The Company’s liquidity needs up to December 4, 2025 had been satisfied through the loan under an unsecured promissory note from the Sponsor of up to $300,000 (see Note 4). At December 4, 2025, the Company had cash of $916,261 and working capital of $892,348.

In order to finance transaction costs in connection with a Business Combination, the Sponsor or an affiliate of the Sponsor or certain of the Company’s directors and officers may, but are not obligated to, loan the Company funds as may be required (“Working Capital Loans”). If the Company completes a Business Combination, the Company would 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 a Business Combination does not close, the Company may use a portion of 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. Except for the foregoing, the terms of such Working Capital Loans, if any, have not been determined and no written agreements exist with respect to such loans. The Working Capital Loans would either be repaid upon consummation of a Business Combination, without interest, or, at the lender’s discretion, up to $2,500,000 of such Working Capital Loans may be convertible into units of the post-Business Combination entity at a price of $10.00 per units. The units and the underlying securities would be identical to the Private Placement Units. As of December 4, 2025, there were no amounts outstanding under the Working Capital Loans.

In connection with the Company’s assessment of going concern considerations in accordance with ASC 205-40, “Presentation of Financial Statements – Going Concern,” the Company does not believe it will need to raise additional funds in order to meet the expenditures required for operating its business. However, if the estimate of the costs of identifying a target business, undertaking in-depth due diligence and negotiating a Business Combination are less than the actual amount necessary to do so, the Company may have insufficient funds available to operate its business prior to the initial Business Combination. Management has determined that the Company has sufficient funds to finance the working capital needs of the Company within one year from the date of issuance of the financial statement.

Note 2 — Significant Accounting Policies (cont.)

Emerging Growth Company Status

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 statement 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 financial statement in conformity with U.S. GAAP requires 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 financial statement. Actual results could differ 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 cash of $916,261 and did not have any cash equivalents as of December 4, 2025.

Cash Held in Trust Account

As of December 4, 2025, the assets held in the Trust Account, amounting to $276,000,000, were held in cash.

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 Associated with the Initial Public Offering

The Company complies with the requirements of 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. Financial Accounting Standards Board (“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 Class A ordinary shares subject to possible redemption were charged to temporary equity and offering costs allocated to the Class A ordinary shares not subject to possible redemption were charged to permanent equity. Offering costs allocated to the Public Warrants and Private Placement Warrants were charged to statement of operations as Public and Private Placement Warrants after management’s evaluation are accounted for under liability treatment.

Note 2 — Significant Accounting Policies (cont.)

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. U.S. 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.

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 December 4, 2025, there were no unrecognized tax benefits and no amounts accrued for interest and penalties. The Company is currently not aware of any issues under review that could result in significant payments, accruals or material deviation from its position.

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 zero for the period presented.

Class A Ordinary Shares Subject to Possible Redemption

The Company’s ordinary shares sold as part of the Units in the Initial Public Offering 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 redemption outside of permanent equity as the redemption provisions are not solely within the control of the Company. The Public Shares sold as part of the Units in the Initial Public Offering were issued with other freestanding instruments (i.e., Public Warrants) and as such, the initial carrying value of Public Shares classified as temporary equity were the allocated proceeds determined in accordance with ASC 470-20. The Public Shares are subject to ASC 480-10-S99 and are currently not redeemable as the redemption is contingent upon the occurrence of events mentioned above. According to ASC 480-10-S99-15, no subsequent adjustment is needed if it is not probable that the instrument will become redeemable. As of December 4, 2025, the Class A ordinary shares subject to possible redemption reflected in the balance sheet are reconciled in the following table:

Gross proceeds	$	276,000,000

Warrants

The Company accounts for the Public Warrants and Private Placement Warrants issued in connection with the Initial Public Offering and the private placement in accordance with the guidance contained in FASB ASC Topic 815, “Derivatives and Hedging”. Accordingly, the Company evaluated and classified the Public Warrant and Private Placement Warrant instruments under liability treatment at their fair value. As of December 4, 2025, there were 9,200,000 Public Warrants and 65,000 Private Placement Warrants outstanding.

Recent Accounting Pronouncements

In November 2023, the FASB issued Accounting Standards Update (“ASU”) 2023-07, “Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures.” The amendments in this ASU require disclosures, on an annual and interim basis, of significant segment expenses that are regularly provided to the chief operating decision maker (“CODM”), as well as the aggregate amount of other segment items included in the reported measure of segment profit or loss. The ASU requires that a public entity disclose the title and position of the CODM and an explanation of how the CODM uses the reported measure(s) of segment profit or loss in assessing segment performance and deciding how to allocate resources. Public entities will be required to provide all annual disclosures currently required by Topic 280 in interim periods, and entities with a single reportable segment are required to provide all the disclosures required by the amendments in this ASU and existing segment disclosures in Topic 280. This ASU is effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024, with early adoption permitted. The Company adopted ASU 2023-07 on May 29, 2025 (inception).

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 financial statement.

Note 3 — Initial Public Offering

Public Units

Pursuant to the Initial Public Offering on December 4, 2025, the Company sold 27,600,000 Units at a price of $10.00 per Unit, which includes the full exercise of the underwriters’ over-allotment option in the amount of 3,600,000 Units. Each Unit consists of one Class A ordinary share and one-third of one redeemable warrant. Each whole warrant entitles the holder to purchase one Class A ordinary share at a price of $11.50 per share, subject to adjustment. 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 30 days after the completion of the initial Business Combination and will expire five years after the completion of the initial Business Combination.

Public Warrants

Each whole warrant entitles the holder to purchase one Class A ordinary share at a price of $11.50 per share, subject to adjustment as discussed herein. The warrants will become exercisable 30 days after the completion of the initial Business Combination and will expire five years after the completion of the Company’s initial Business Combination, at 5:00 p.m., New York City time, or earlier upon redemption or liquidation.

In addition, if (x) the Company issue 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 share of Class A ordinary shares (with such issue price or effective issue price to be determined in good faith by the Company’s board of directors (including consideration of the market price) and, in the case of any such issuance to the initial shareholders or their affiliates, without taking into account any Founder Shares (as defined in Note 4) held by the initial shareholders 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 the 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 Class A ordinary shares during the 20 trading day period starting on the trading day prior to the day on which the Company consummates the 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, and the $18.00 per share redemption trigger price will be adjusted (to the nearest cent) to be equal to 180% of the higher of the Market Value and the Newly Issued Price.

The Company will not be obligated to deliver any shares of 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 with respect to the ordinary shares underlying the warrants is then effective and a prospectus is current. No warrant will be exercisable and the Company will not be obligated to issue ordinary shares upon exercise of a warrant unless ordinary shares issuable upon such warrant exercise has been registered, qualified or deemed to be exempt under the securities laws of the state of residence of the registered holder of the warrants. In no event will the Company be required to net cash settle any warrant.

In the event that a registration statement is not effective for the exercised warrants within specified time periods after the closing of the initial Business Combination, the purchaser of a unit containing such warrant will have paid the full purchase price for the unit solely for the share of ordinary shares underlying such unit.

Redemption of Public Warrants

Once the warrants become exercisable, the Company may redeem the outstanding warrants (except as described herein with respect to the private placement warrants):

· in whole and not in part;

· at a price of $0.01 per warrant;

· upon a minimum of 30 days’ prior written notice of redemption, which the Company refers to as the 30-day redemption period; and

· if, and only if, the closing price of the Class A ordinary shares equals or exceeds $18.00 per share (as adjusted) for any 20 trading days within a 30-trading day period ending on the third trading day prior to the date on which the Company sends the notice of redemption to the warrant holders (the “Reference Value”), provided that a registration statement under the Securities Act covering the issuance of the Class A ordinary shares issuable upon exercise of the warrants is effective and a current prospectus relating to those Class A ordinary shares is available throughout the 30-trading day measurement period.

If the Company calls the Public Warrants for redemption, management will have the option to require all holders that wish to exercise warrants to do so on a cashless basis. In the event of an exercise on a cashless basis, a holder would pay the warrant exercise price by surrendering the warrants for that number of Class A ordinary shares equal to the quotient obtained by dividing (x) the product of the number of Class A ordinary shares underlying the warrants, multiplied by the difference between the exercise price of the warrants and the “fair market value” (as defined in the next sentence) by (y) the fair market value. The “fair market value” for this purpose shall mean the average reported last sale price of the Class A ordinary shares for the 10 trading days ending on the third trading day prior to the date on which the notice of exercise is received by the warrant agent or on which the notice of redemption is sent to the holders of warrants, as applicable.

Note 4 — Related Party Transactions

Private Placement

Simultaneously with the closing of the Initial Public Offering, the Sponsor purchased an aggregate of 195,000 Private Placement Units at a price of $10.00 per Private Placement Unit, or $1,950,000 in the aggregate. Each Unit consists of one Class A ordinary share and one-third of one warrant. Each whole warrant entitles the holder to purchase one Class A ordinary share at a price of $11.50 per share, subject to adjustment. Only whole warrants are exercisable. A portion of the proceeds from the Private Placement Units was added to the proceeds from the Initial Public Offering held in the Trust Account. If the Company does not complete a Business Combination within the Completion Window, the proceeds from the sale of the Private Placement Units will be used to fund the redemption of the Public Shares (subject to the requirements of applicable law).

Founder Shares

On June 5, 2025, the Sponsor made a capital contribution of $25,000, or approximately $0.004 per share, to cover certain of the Company’s expenses, for which the Company issued 5,750,000 founder shares (the “Founder Shares”) to the Sponsor. In December 2025, the Company, through a share capitalization, issued the Sponsor an additional 1,150,000 Class B ordinary shares, as a result of which the Sponsor has purchased and holds an aggregate of 6,900,000 Class B ordinary shares. All share and per share data has been retrospectively presented. Up to 900,000 of the Founder Shares were subject to forfeiture by the Sponsor for no consideration depending on the extent to which the underwriter’s overallotment was exercised. On December 4, 2025, the underwriters exercised their over-allotment option in full as part of the closing of the Initial Public Offering. As such, the 900,000 Founder Shares are no longer subject to forfeiture.

Promissory Note

On June 2, 2025, the Sponsor agreed to loan the Company up to $300,000 to be used for a portion of the expenses of the Initial Public Offering. The loan was non-interest bearing, unsecured and due at the earlier of December 31, 2025 or the closing of the Initial Public Offering. The Company had $217,441 in borrowings under the promissory note, which was repaid at the closing of the Initial Public Offering on December 4, 2025. Borrowings under the note are no longer available.

Administrative Support Agreement

The Company entered into an agreement, commencing on December 2, 2025, to pay the Sponsor a total of $10,000 per month for office space, secretarial, administrative and shared personnel support services. The Company will cease the monthly fees through the earlier of completion of the Company’s initial Business Combination or liquidation. As of December 4, 2025, the Company incurred $1,000 of administrative services fees which is included in accrued expenses in the accompanying balance sheet.

Related Party Loans

In order to finance transaction costs in connection with a Business Combination, the Sponsor or an affiliate of the Sponsor or certain of the Company’s directors and officers may, but are not obligated to, loan the Company funds as may be required (“Working Capital Loans”). If the Company completes a Business Combination, the Company would 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 a Business Combination does not close, the Company may use a portion of 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. Except for the foregoing, the terms of such Working Capital Loans, if any, have not been determined and no written agreements exist with respect to such loans. The Working Capital Loans would either be repaid upon consummation of a Business Combination, without interest, or, at the lender’s discretion, up to $2,500,000 of such Working Capital Loans may be convertible into units of the post-Business Combination entity at a price of $10.00 per units. The units and the underlying securities would be identical to the Private Placement Units. As of December 4, 2025, there were no amounts outstanding under the Working Capital Loans.

Risks 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 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 (SWIFT) 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 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, 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 (i) Founder Shares, which were issued in a private placement prior to the closing of the Initial Public Offering, (ii) Private Placement Units, which were issued in a private placement simultaneously with the closing of the Initial Public Offering and the Class A ordinary shares underlying such Private Placement Warrants and (iii) units that may be issued upon conversion of Working Capital Loans will have registration rights to require the Company to register a sale of any of the Company’s securities held by them pursuant to a registration rights agreement signed on December 2, 2025. The holders of these securities are entitled to make up to three demands, excluding short form demands, that the Company registers such securities. In addition, the holders have certain “piggyback” registration rights with respect to registration statements filed subsequent to the Company’s completion of its initial Business Combination. 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 date of the Initial Public Offering to purchase up to 3,600,000 additional Units to cover over-allotments, if any, at the Initial Public Offering price less the underwriting discounts and commissions. On December 4, 2025, simultaneously with the closing of the Initial Public Offering, the underwriters elected to fully exercise the over-allotment option to purchase the additional 3,600,000 Units at a price of $10.00 per Unit.

Note 6 — Shareholders’ Deficit (cont.)

Prior to the consummation of the initial Business Combination, only holders of Class B ordinary shares will have the right to vote on the appointment or removal of directors. Holders of the Class A ordinary shares will not be entitled to vote on the appointment or removal of directors during such time. These provisions of the Company’s amended and restated memorandum and articles of association may only be amended if approved by a majority of at least 90% of its ordinary shares voting at a shareholder meeting.

The Class B ordinary shares will automatically convert into Class A ordinary shares upon the consummation of the initial Business Combination on a one-for-one basis, subject to adjustment for share subdivisions, share dividends, reorganizations, recapitalizations and the like, and subject to further adjustment. 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, on an as-converted basis, 20% of the total number of shares of Class A ordinary shares outstanding after such conversion, including 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 or rights exercisable for or convertible into Class A ordinary shares issued, or to be issued, to any seller in the initial Business Combination and any Private Placement Units issued to the Sponsor, officers or directors upon conversion of Working Capital Loans; provided that such conversion of Founder Shares will never occur on a less than one-for-one basis.

Note 7 — Fair Value Measurements

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. U.S. 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.

The following table presents information about the Company’s liabilities that are measured at fair value as of December 4, 2025, and indicates the fair value hierarchy of the valuation inputs the Company utilized to determine such fair value:

	Level		December 4, 2025
Liabilities:
Derivative liability – Public Warrants		3	$	3,652,400
Derivative liability – Private Warrants		3	$	25,935

Note 8 — Segment Information

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 CODM, or group, in deciding how to allocate resources and assess performance.

The Company’s CODM has been identified as the Chief Financial Officer, who reviews the assets, operating results, and financial metrics 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 one reportable segment.

The CODM assesses performance for the single segment and decides how to allocate resources. The measure of segment assets is reported on the balance sheet as total assets. When evaluating the Company’s performance and making key decisions regarding resource allocation the CODM reviews several key metrics, which include the following:

	December 4, 2025
Cash	$	916,261
Cash held in Trust Account	$	276,000,000

Note 9 — Subsequent Events

The Company evaluated subsequent events and transactions that occurred after the balance sheet date through December 10, 2025, the date that the financial statement was available to be issued. Based upon this review, the Company did not identify any subsequent events that would have required adjustment or disclosure in the financial statement.
