REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and

Shareholders of GigCapital8 Corp.

Opinion on the Financial Statements

We have audited the accompanying balance sheet of GigCapital8 Corp. (a Cayman Islands exempted company) (the “Company”) as of October 7, 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 October 7, 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) (“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.

GIGCAPITAL8 CORP.

NOTES TO BALANCE SHEET

1. DESCRIPTION OF ORGANIZATION AND BUSINESS OPERATIONS

Organization and General

GigCapital8 Corp. (the “Company”) was incorporated as a Cayman Islands exempted company on June 30, 2025. The Company was formed for the purpose of effecting a merger, capital share exchange, asset acquisition, share purchase, reorganization or similar business combination with one or more businesses (the “Business Combination”). The Company will be 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 Startups Act of 2012 (the “JOBS Act”). The Company’s sponsor is GigAcquisitions8 Corp., a Cayman Island exempted company (the “Sponsor” and is sometimes referred to as the “Founder”).

As of October 7, 2025, the Company had not commenced any operations. All activity for the period from June 30, 2025 (date of inception) through October 7, 2025 relates to the Company’s formation and the initial public offering (the “Offering”) described below. The Company will not generate any operating revenues until after completion of the Business Combination, at the earliest. The Company will generate non-operating income in the form of interest income on cash and cash equivalents from the proceeds derived from the Offering. The Company has selected December 31 as its fiscal year end.

On September 30, 2025, the Registration Statement on Form S-1 (File No. 333-289479), as amended (the “Registration Statement”), relating to the Offering of the Company was declared effective by the Securities and Exchange Commission (the “SEC”).

The Company entered into an underwriting agreement with D. Boral Capital LLC (the “Underwriter”) on October 3, 2025 to conduct the Offering of 22,000,000 units (the “Units”) in the amount of $220.0 million in gross proceeds, with a 45-day option provided to the Underwriter to purchase up to 3,300,000 additional Units solely to cover over-allotments, if any, in the amount of up to $33.0 million in additional gross proceeds. Each Unit consists of one share of the Company’s Class A ordinary shares, $0.0001 par value, and one right to receive one-fifth (1/5) of one Class A ordinary share upon the consummation of an initial Business Combination.

On October 7, 2025, the Company consummated the Offering of 25,300,000 Units, including the issuance of 3,300,000 Units as a result of the Underwriter’s exercise in full of their over-allotment option. The Units were sold at a price of $10.00 per Unit, generating gross proceeds to the Company of $253,000,000.

Certain institutional accredited investors (none of which are affiliated with any member of management, the Sponsor or any other investor (the “non-managing investors”)) purchased an aggregate of (a) 2,964,203 Class B ordinary shares (the “Private Investor Shares”) at a purchase price per Class B ordinary share of $0.023254, and (b) an aggregate of 262,425 private placement units consisting of one Class A ordinary share and one right to receive one-fifth (1/5) of one Class A ordinary share upon consummation of the initial Business Combination at a price of $9.7374 per unit in a private placement that occurred simultaneously with the completion of the Offering (the “Private Placement Unit”) for an aggregate purchase price of $2,624,266. The Private Investor Shares along with the Founder Shares (as defined below - see Note 4) collectively represent 30% of the outstanding ordinary shares, excluding the private placement shares that are an underlying security to the Private Placement Units. The private placement proceeds will be used to pay for business, legal and accounting due diligence expenses on acquisition targets and continuing general and administration expenses.

Following the closing of the Offering, net proceeds in the amount of $253,000,000 from the sale of the Units in the Offering were placed in a trust account (the “Trust Account”) (discussed below).

Transaction costs amounted to $1,788,054, consisting of $1,025,000 of underwriting fees and $763,054 of offering costs. The Company’s remaining cash after payment of the offering costs is held outside of the Trust Account for working capital purposes.

The Trust Account

The funds in the Trust Account will be invested only in U.S. government treasury bills with a maturity of one hundred and eighty-five (185) days or less or in money market funds meeting certain conditions under Rule 2a-7 under the Investment Company Act of 1940 which invest only in direct U.S. government obligations. Funds will remain in the Trust Account until the earlier of (i) the completion of an initial Business Combination or (ii) the distribution of the Trust Account as described below.

F-4

The Company’s memorandum and articles of association provides that, other than the withdrawal of interest to pay taxes none of the funds held in the Trust Account will be released until the earlier of: (1) the completion of an initial Business Combination; (2) the redemption of 100% of the outstanding public shares if the Company has not completed an initial Business Combination within 24 months from the closing of the Offering or (3) the redemption of any public shares properly tendered in connection with a shareholder vote to amend the memorandum and articles of association (A) to modify the substance or timing of the Company’s obligation to redeem 100% of the Company’s public shares if the Company does not complete its initial Business Combination within the required time period or (B) with respect to any other provision relating to the Company’s pre-business combination activity and related shareholders’ rights.

Business Combination

The Company’s management has broad discretion with respect to the specific application of the net proceeds of the Offering, although substantially all of the net proceeds of the Offering are intended to be generally applied toward consummating a Business Combination with (or acquisition of) a Target Business. As used herein, “Target Business” must be with one or more target businesses that together have a fair market value equal to at least 80% of the balance in the Trust Account (less withdrawals to pay taxes, if any, and such withdrawals can only be made from interest and not from the principal held in the Trust Account) at the time the Company signs a definitive agreement in connection with the Business Combination. There is no assurance that the Company will be able to successfully effect a Business Combination.

The Company, after signing a definitive agreement for a Business Combination, will either (i) seek shareholder approval of the Business Combination at a meeting called for such purpose in connection with which shareholders may seek to redeem their shares, regardless of whether they vote for or against the Business Combination, for cash equal to their pro rata share of 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 but less taxes payable, or (ii) provide shareholders with the opportunity to have their shares redeemed by the Company by means of a tender offer (and thereby avoid the need for a shareholder vote) for an amount in cash equal to their pro rata share of the aggregate amount then on deposit in the Trust Account as of two business days prior to commencement of the tender offer, including interest but less taxes payable. The decision as to whether the Company will seek shareholder approval of the Business Combination or will allow shareholders to redeem their shares in 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 otherwise require the Company to seek shareholder approval unless a vote is required by the Nasdaq Stock Market LLC (“Nasdaq”) rules. If the Company seeks shareholder approval, it will complete its Business Combination only if a majority of the outstanding shares are voted in favor of the Business Combination.

If the Company holds a shareholder vote or there is a tender offer for shares in connection with the Business Combination, a public shareholder will have the right to redeem its shares for an amount in cash equal to its pro rata share of 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 but less taxes payable. As a result, such ordinary shares are recorded at redemption amount and classified as temporary equity. The amount in the Trust Account of $253,000,000 represents 25,300,000 public shares at $10.00 per public share.

The Company has 24 months from the closing date of the Offering to complete its initial Business Combination. If the Company does not complete a Business Combination within this period of time, it shall (i) cease all operations except for the purposes of winding up; (ii) as promptly as reasonably possible, but not more than ten business days thereafter, redeem the public shares for a per share pro rata portion of the Trust Account, including interest, but less amounts withdrawn to pay taxes, if any (less up to $100,000 of such net interest to pay dissolution expenses); and (iii) as promptly as possible following such redemption, dissolve and liquidate the balance of the Company’s net assets to its creditors and remaining shareholders, as part of its plan of dissolution and liquidation. The Sponsor and those certain institutional investors participating in the private placement each entered into agreements with the Company, pursuant to which they will agree: (1) to waive their redemption rights with respect to their Founder Shares, Private Investor Shares, private placement shares and any Class A ordinary shares issuable upon conversion thereof in connection with the consummation of the Company’s initial Business Combination or a tender offer conducted prior to a Business Combination or in connection with it; (2) to waive their rights to liquidating distributions from the Trust Account with respect to their Founder Shares, Private Investor Shares and private placement shares if the Company fails to complete an initial Business Combination within 24 months from the closing of the Offering, 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 an initial Business Combination within the prescribed time frame; and (3) to waive their redemption rights with respect

F-5

to their Founder Shares, Private Investor Shares and private placement shares in connection with a shareholder vote to approve an amendment to the Company’s amended and restated memorandum and articles of association that would modify the substance or timing of the Company’s obligation to redeem 100% of the Company’s public shares if the Company does not timely complete an initial Business Combination or with respect to any other provision relating to shareholders’ rights or pre-business combination activity.

In the event of such distribution, it is possible that the per share value of the residual assets remaining available for distribution (including Trust Account assets) will be less than the initial public offering price per unit in the Offering.

Liquidity

Prior to the completion of the Offering, the Company lacked the liquidity it needed to sustain operations for a reasonable period of time, which is considered to be one year from the issuance date of the financial statement. The Company has since completed its Offering at which time capital in excess of the funds deposited in the Trust Account and/or used to fund Offering expenses was released to the Company for general working capital purposes. Accordingly, management has since re-evaluated the Company’s liquidity and financial condition and determined that sufficient capital exists to sustain operations for at least one year from the date that the financial statement was issued, and therefore the substantial doubt has been alleviated.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation

The financial statement of the Company has been prepared in conformity with accounting principles generally accepted in the United States of America.

Emerging Growth Company

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 Securities Exchange Act of 1934, as amended) are required to comply with the new or revised financial accounting standards. The JOBS Act provides that a 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 an accounting 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 accounting standard at the time private companies adopt the new or revised standard.

Concentration of Credit Risk

Financial instruments that potentially subject the Company to concentrations of credit risk consist of a cash account and the Trust Account in financial institutions, which at times, may exceed federally insured limits. The Company has not experienced losses on these accounts and management believes the Company is not exposed to significant risks on such accounts.

Cash and Cash Equivalents

The Company considers all short-term investments with a maturity of three months or less when purchased to be cash equivalents. The Company did not have any cash equivalents as of October 7, 2025.

Cash and Marketable Securities Held in Trust Account

As of October 7, 2025, the assets held in the Trust Account consisted of cash.

Offering Costs

The Company complies with the requirements of Accounting Standards Codification (“ASC”) 340-10-S99-1 and SEC Staff Accounting Bulletin (“SAB”) Topic 5A – “Expenses of Offering.” Offering costs in the amount of $1,788,054 consist principally of professional and registration fees incurred through the balance sheet date that are related to the Offering. Offering costs were allocated to the separable financial instruments issued in the Offering based on a relative fair value basis, compared to total proceeds received. Offering costs allocated to the public shares were charged to temporary equity and Offering costs allocated to public rights (as defined in Note 3) were charged to shareholders’ equity upon the completion of the Offering.

F-6

Class A Ordinary Shares Subject to Possible Redemption

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 the Company’s control) are classified as temporary equity. At all other times, ordinary shares are classified as shareholders’ equity (deficit). The Company’s Class A ordinary shares feature certain redemption rights that are considered to be outside of the Company’s control and subject to occurrence of uncertain future events. Accordingly, as of October 7, 2025, Class A ordinary shares subject to possible redemption are presented at redemption value as temporary equity, outside of the shareholders’ equity section of the Company’s balance sheet. Immediately upon the closing of the Offering, the Company recognized the accretion from initial book value to redemption value. The change in the carrying value of redeemable ordinary shares resulted in charges against additional paid-in capital. As of October 7, 2025, 25,300,000 shares of Class A ordinary shares were issued and outstanding and subject to possible redemption.

As of October 7, 2025, the Class A ordinary shares subject to possible redemption reflected on the balance sheet are reconciled in the following table:


	As of October 7, 2025
Gross proceeds	$	253,000,000
Less:
Proceeds allocated to public rights		(10,626,000	)
Ordinary share issuance costs		(1,712,956	)
Plus:
Accretion of carrying value to redemption value		12,338,956

Class A ordinary shares subject to possible redemption	$	253,000,000

Financial Instruments

The fair value of the Company’s assets and liabilities approximates the carrying amounts represented in the balance sheet.

Use of Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America 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 financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

Segment Information

Operating segments are defined as components of an enterprise that engage in business activities from which it may recognize revenues and incur expenses, and 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 one reportable segment.

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 statement of operations and comprehensive loss as net income or loss. The key measures of segment profit or loss reviewed by the CODM are general and administrative expenses. 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 expenses to manage, maintain and enforce all contractual agreements to ensure costs are aligned with all agreements and budget.

Income Taxes

The Company follows the asset and liability method of accounting for income taxes under ASC 740, “Income Taxes” (“ASC 740”). Deferred tax assets and liabilities are recognized for the estimated future tax consequences attributable to differences between the financial statements carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that included the enactment date. Valuation allowances are established, when necessary, to reduce deferred tax assets to the amount expected to be realized.

F-7

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 recognizes accrued interest and penalties related to unrecognized tax benefits as income tax expense. There were no unrecognized tax benefits and no amounts accrued for interest and penalties as of October 7, 2025. 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, and the Company believes it is presently not subject to income taxes or income tax filing requirements in the United States. As such, the Company’s tax provision was zero for the period presented.

Share Rights

The Company accounted for the public and private placement rights issued in connection with the Offering and the private placement in accordance with the guidance contained in ASC Topic 815, “Derivatives and Hedging”. Accordingly, the Company evaluated and classified the rights under equity treatment at their assigned value.

Recent Accounting Pronouncements

The Company does not believe that any recently issued, but not yet effective, accounting pronouncements, if currently adopted, would have a material effect on the Company’s balance sheet.

3. OFFERING

On October 7, 2025 the Company completed the Offering whereby the Company sold 25,300,000 Units at a price of $10.00 per Unit. Each Unit consists of one share of the Company’s Class A ordinary shares, $0.0001 par value and one right to receive one-fifth (1/5) of one Class A ordinary share upon consummation of the initial Business Combination.

The Company will not issue fractional shares in connection with an exchange of rights. Fractional shares will either be rounded down to the nearest whole share or otherwise determined by the board of directors as provided by Cayman Islands laws. As a result, the holder must hold rights in multiples of five in order to receive shares for all of the rights upon closing of an initial Business Combination.

The Company paid an underwriting discount of $0.0405 per Unit to the Underwriter at the closing of the Offering.

The non-managing investors purchased an aggregate of (a) 2,964,203 Class B ordinary shares at a purchase price per Class B ordinary share of $0.023254, and (b) an aggregate of 262,425 Private Placement Units consisting of one Class A ordinary share and one right to receive one-fifth (1/5) of one Class A ordinary share upon consummation of the initial Business Combination at a price of $9.7374 per unit in a private placement that occurred simultaneously with the completion of the Offering for an aggregate purchase price of $2,624,266. The Private Investor Shares along with the Founder Shares collectively represent 30% of the outstanding ordinary shares, excluding the private placement shares that are an underlying security to the Private Placement Units. The private placement proceeds will be used to pay for business, legal and accounting due diligence expenses on acquisition targets and continuing general and administration expenses.

4. RELATED PARTY TRANSACTIONS

Founder Shares

On June 30, 2025 (date of inception), one Class B ordinary share that was allotted to Harneys Fiduciary (Cayman) Limited (“Harneys Fiduciary”) upon the Company’s formation was transferred by Harneys Fiduciary to the Founder and 8,099,613 Class B ordinary shares (the 8,099,614 Class B ordinary shares collectively are the “Founder Shares”) were issued to the Founder for an aggregate purchase price of $25,000. On July 18, 2025, the Founder surrendered 249,385 Class B ordinary shares to the Company (which were cancelled) for no consideration, with the resulting 7,850,229 Founder Shares paid for at a purchase price of $0.00318 per share. On October 3, 2025, the Sponsor transferred 5,000 Founder Shares to its Chief Financial Officer, solely in consideration of future services. The 5,000 Founder Shares granted to the Chief Financial Officer are subject to forfeiture back to the Sponsor in the event the Chief Financial Officer resigns or is removed for cause prior to consummation of an initial Business Combination.

F-8

At the consummation of the Offering the Founder sold 375,397 Founder Shares in the aggregate to four board nominees (“Insiders”) at an aggregate price of $9,244, or $0.02462 per share, and 1,416,665 Founder Shares to Lynrock Lake Master Fund LP (“Lynrock”) at an aggregate price of $13,130. Following this sale of Founders Shares, the Founder holds 6,053,167 Founder Shares, and the price paid by the Founder for the 6,053,167 Founder Shares which it is retaining will be $2,626, or $0.000434 per share. The Class B ordinary shares owned by the Founder, Insiders, Lynrock and non-managing investors represents 30% of the Company’s issued and outstanding Class A and Class B ordinary shares after the Offering, excluding the private placement shares that are an underlying security to the Private Placement Units.

Private Placement Units

Simultaneously with the closing of the Offering, the Founder, Insiders and Lynrock purchased from the Company 95,200 Private Placement Units pursuant to a Unit Purchase Agreement. In addition, as discussed in Note 3, the non-managing investors purchased 262,425 Private Placement Units at a price of $9.7374 per Private Placement Unit. Each five rights included in the Private Placement Units entitle the holder thereof to receive one Class A ordinary share upon the consummation of the initial Business Combination. The Company will not issue fractional shares in connection with an exchange of rights. Fractional shares will either be rounded down to the nearest whole share or otherwise determined by the board of directors as provided by Cayman Islands laws. As a result, the holder must hold rights in multiples of five in order to receive shares for all of their rights upon closing of an initial Business Combination. If the Company is unable to complete an initial Business Combination within the required time period and, as a result, the Company redeems the public shares for the funds held in the trust account, holders of rights will not receive any of such funds for their rights and the rights will expire worthless.

The Company’s Founder, Insiders, Lynrock and the non-managing investors have each agreed not to transfer, assign or sell any of their respective Founder Shares, Private Investor Shares, Private Placement Units or underlying securities to the Private Placement Units that they may hold from the date of the Offering until the date that is (i) in the case of the Founder Shares and the Private Investor Shares, the earlier of (A) 6 months after the date of the consummation of the Company’s initial Business Combination or (B) subsequent to the Company’s initial Business Combination, (x) the date on which the last sale price of the Company’s Class A ordinary shares equals or exceeds $11.50 per share (as adjusted for share splits, share dividends, reorganizations, recapitalizations and the like) for any 20 trading days within any 30-trading day period commencing at least 90 days after the Company’s initial Business Combination, or (y) the date on which the Company consummates a liquidation, merger, share exchange or other similar transaction after the Company’s initial Business Combination which results in all of the Company’s shareholders having the right to exchange their ordinary shares for cash, securities or other property, and (ii) in the case of the Private Placement Units (and its underlying securities), until 30 days after the completion of the Company’s initial Business Combination.

If the Company does not complete a Business Combination, then a portion of the proceeds from the sale of the Private Investor Shares and Private Placement Units will be part of the liquidating distribution to the public shareholders.

Registration Rights

The Company’s Founder, Insiders, Lynrock and the non-managing investors and their permitted transferees are entitled to registration rights pursuant to a registration rights agreement signed on the date of the Offering with respect to their respective Founder Shares, Private Investor Shares, Private Placement Units or the underlying securities to the Private Placement Units. These holders will be entitled to make up to three demands, excluding short form registration demands, that the Company register such securities for sale under the Securities Act. In addition, these holders will have “piggy-back” registration rights to include their securities in other registration statements filed by the Company. The Company will bear the expenses incurred in connection with the filing of any such registration statements. There will be no penalties associated with delays in registering the securities under the proposed registration rights agreement.

Related Party Loan

The Company entered into a promissory note with the Sponsor with a principal amount of $100,000 (the “Promissory Note”), of which none remained outstanding as of October 7, 2025. The proceeds were used for the payment of expenses related to the Offering. The Promissory Note was non-interest bearing, unsecured and was due on the earlier of (i) December 31, 2025 or (ii) the date on which the Company consummates an initial public offering of its securities.

F-9

Administrative Services Agreement and Other Agreements

The Company has agreed to pay $30,000 a month for office space, administrative services and secretarial support to an affiliate of the Founder, GigManagement, LLC. Services commenced on October 6, 2025, the date the securities were first listed on Nasdaq, and will terminate upon the earlier of the consummation by the Company of a Business Combination or the liquidation of the Company.

5. SHAREHOLDERS’ EQUITY

Preferred Shares

The Company is authorized to issue 1,000,000 shares of preferred shares with such designations, voting and other rights and preferences as may be determined from time to time by the board of directors. As of October 7, 2025, there were no preferred shares issued and outstanding.

Rights

Except in cases where the Company is not the surviving company in an initial Business Combination, each holder of a right will automatically receive one-fifth (1/5) of one Class A ordinary share upon consummation of an initial Business Combination. In the event the Company is not the surviving company upon completion of an initial Business Combination, each holder of a right will be required to affirmatively convert his, her or its rights in order to receive the one-fifth (1/5) of a Class A ordinary share of the new entity underlying each right upon consummation of the initial Business Combination. The Company will not issue fractional shares in connection with an exchange of rights. Fractional shares will either be rounded down to the nearest whole share or otherwise determined by the board of directors as provided by Cayman Islands laws. As a result, each holder must hold rights in multiples of five in order to receive shares for all of the rights upon closing of an initial Business Combination. If the Company is unable to complete an initial Business Combination within the required time period and redeems the public shares for the funds held in the Trust Account, holders of rights will not receive any of such funds for their rights and the rights will expire worthless.

Stock-based Compensation

Included in the outstanding Class B ordinary shares are 5,000 Founder Shares issued to Ms. Marshall, the Company’s Chief Financial Officer solely in consideration of future services pursuant to the Grant of Insider Shares Agreement dated September 26, 2025, between the Company and Ms. Marshall. The 5,000 Founder Shares issued to Ms. Marshall are subject to forfeiture as described in Note 4. If an initial Business Combination occurs and the 5,000 Founder Shares have not been previously forfeited, the fair value of the Class B ordinary shares on the date the shares vest will be recognized as stock-based compensation in the Company’s statement of operations and comprehensive loss when the completion of the Business Combination becomes probable.

6. FAIR VALUE MEASUREMENTS

The fair value of the Company’s financial assets and liabilities reflects management’s estimate of amounts that the Company would have received in connection with the sale of the assets or paid in connection with the transfer of the liabilities in an orderly transaction between market participants at the measurement date. In connection with measuring the fair value of its assets and liabilities, the Company seeks to maximize the use of observable inputs (market data obtained from independent sources) and to minimize the use of unobservable inputs (internal assumptions about how market participants would price assets and liabilities). The following fair value hierarchy is used to classify assets and liabilities based on the observable inputs and unobservable inputs used in order to value the assets and liabilities:

Level 1: Quoted prices in active markets for identical assets or liabilities. An active market for an asset or liability is a market in which transactions for the asset or liability occur with sufficient frequency and volume to provide pricing information on an ongoing basis.

Level 2: Observable inputs other than Level 1 inputs. Examples of Level 2 inputs include quoted prices in active markets for similar assets or liabilities and quoted prices for identical assets or liabilities in markets that are not active.

Level 3: Unobservable inputs which are supported by little or no market activity and which are significant to the fair value of the assets or liabilities.

The public rights have been classified within shareholders’ equity and will not require remeasurement after issuance. The public rights were classified as Level 3 of the fair value hierarchy at the measurement dates due to the use of unobservable inputs inherent in assumptions related to the market adjustments as noted below. The following table presents the quantitative information regarding market assumptions used in the valuation of the public rights:


	As of October 7, 2025
Trade price of Unit	$	10.00
Share price	$	9.58
Market adjustment ⁽¹⁾		4.2	%
Fair value per right	$	0.42

(1)

Market adjustment reflects additional factors not fully captured by low volatility selection, which may include likelihood of the Business Combination occurring, market perception of lack of available or suitable targets, or possible post-acquisition decline of share price. The adjustment is determined by comparing traded right prices to simulated model outputs.

There were no financial assets or liabilities measured on a recurring basis as of October 7, 2025.

7. SUBSEQUENT EVENTS

The Company evaluated subsequent events that occurred after the balance sheet date through October 14, 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 to or disclosure in the financial statement.
