NOTE 1 — ORGANIZATION AND PLAN OF BUSINESS OPERATIONS

GP-Act III Acquisition Corp. (formerly known as GP Investments Acquisition Corp. II) (the “Company”) is a blank check company incorporated as a Cayman Islands exempted company on November 23, 2020. 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 (“business combination”).

The Company is not limited to a particular industry or geographic region for purposes of completing a business combination. The Company is an early stage and emerging growth company and, as such, the Company is subject to all of the risks associated with early stage and emerging growth companies.

As of June 30, 2026, the Company had not commenced any operations. All activity for the period from November 23, 2020 (inception) through June 30, 2026 relates to the Company’s formation, and since the Initial Public Offering (as defined below), and subsequent to the Initial Public Offering, identifying a target company and negotiating the terms of a Business Combination. The Company will not generate any operating revenues until after the completion of a business combination, at the earliest. The Company generates non-operating income in the form of interest income from the proceeds derived from the Initial Public Offering. The Company has selected December 31 as its fiscal year end.

The registration statement for the Company’s Initial Public Offering was declared effective on May 8, 2024. On May 13, 2024, the Company consummated the Initial Public Offering of 28,750,000 units (the “Units” and, with respect to the Class A ordinary shares included in the Units being offered, the “Public Shares”), which includes the full exercise by the underwriter of its over-allotment option in the amount of 3,750,000, at $10.00 per Unit, generating gross proceeds of $287,500,000, which is discussed in Note 3. Simultaneously with the closing of the Initial Public Offering, the Company consummated the sale of 7,000,000 private placement warrants (the “Private Placement Warrants”) at a price of $1.00 per Private Placement Warrant to GP-Act III Sponsor LLC (“Sponsor HoldCo”) and Cantor Fitzgerald & Co. (“Cantor”), see Note 4.

Transaction costs amounted to $20,269,166 consisting of $5,000,000 of cash underwriting fees, $13,687,500 of deferred underwriting fees (see additional discussion in Note 6), and $1,581,666 of other offering costs.

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 the Private Placement Warrants, although substantially all of the net proceeds are intended to be applied generally toward completing a business combination. The Company must complete its initial business combination with one or more target businesses that together have a fair market value equal to at least 80% of the net assets held in the Trust Account (as defined below) (excluding any deferred underwriting commissions held in the Trust Account) at the time of the agreement to enter into a business combination. The Company will only complete a business combination if the post-business combination company owns or acquires 50% or more of the issued and outstanding voting securities of the target or otherwise acquires a controlling interest in the target business sufficient for it not to be required to register as an investment company under the Investment Company Act of 1940, as amended (the “Investment Company Act”). There is no assurance that the Company will be able to successfully effect a business combination.

Following the closing of the Initial Public Offering, on May 13, 2024, an amount of $287,500,000 ($10.00 per Unit) from the net proceeds of the sale of the Units in the Initial Public Offering and the sale of the Private Placement Warrants was placed in the trust account (“Trust Account”) and will be invested or held either (i) in U.S. government securities, within the meaning set forth in Section 2(a)(16) of the Investment Company Act, with a maturity of 185 days or less, or in any open-ended investment company that holds itself out as a money market fund meeting certain conditions of Rule 2a-7 of the Investment Company Act, (ii) as uninvested cash, or (iii) an interest bearing bank demand deposit account or other accounts at a bank, as determined by the Company, until the earlier of: (i) the completion of a business combination and (ii) the distribution of the funds in the Trust Account to the Company’s shareholders, as described below.

GP-ACT III ACQUISITION CORP.

NOTES TO CONDENSED FINANCIAL STATEMENTS

JUNE 30, 2026

(UNAUDITED)

The Company will provide its shareholders with the opportunity to redeem all or a portion of their Public Shares upon the completion of a business combination either (i) in connection with a general meeting called to approve the business combination or (ii) by means of a tender offer. The decision as to whether the Company will seek shareholder approval of a business combination or conduct a tender offer will be made by the Company. The shareholders will be entitled to redeem their shares for a pro rata portion of the amount held in the Trust Account (initially $10.00 per share), calculated as of two business days prior to the completion of a business combination, including any pro rata interest earned on the funds held in the Trust Account and not previously released to the Company to pay its tax obligations. There will be no redemption rights upon the completion of a business combination with respect to the Company’s warrants. The Class A ordinary shares were recorded at redemption value and classified as temporary equity at the Initial Public Offering, in accordance with Accounting Standards Codification (“ASC”) Topic 480 “Distinguishing Liabilities from Equity.”

If the Company seeks shareholder approval in connection with a business combination, it receives an ordinary resolution under Cayman Islands law approving a business combination, which requires the affirmative vote of a majority of the shareholders who vote at a general meeting of the Company. If a shareholder vote is not required under applicable law or stock exchange listing requirements and the Company does not decide to hold a shareholder vote for business or other reasons, the Company will, pursuant to its Amended and Restated Memorandum and Articles of Association, conduct the redemptions pursuant to the tender offer rules of the Securities and Exchange Commission (“SEC”), and file tender offer documents containing substantially the same information as would be included in a proxy statement with the SEC prior to completing a business combination. If the Company seeks shareholder approval in connection with a business combination, Sponsor HoldCo has agreed to vote its Founder Shares (as defined in Note 5) and any Public Shares purchased in or after the Initial Public Offering in favor of approving a business combination and to waive its redemption rights with respect to any such shares in connection with a shareholder vote to approve a business combination. Additionally, each public shareholder may elect to redeem its Public Shares, without voting, and if they do vote, irrespective of whether they vote for or against a proposed business combination.

Notwithstanding the foregoing, if the Company seeks shareholder approval of a business combination and it does not conduct redemptions pursuant to the tender offer rules, the Company’s Amended and Restated Memorandum and Articles of Association provides that a public shareholder, together with any affiliate of such shareholder or any other person with whom such shareholder is acting in concert or as a “group” (as defined under Section 13 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”)), will be restricted from redeeming its shares with respect to more than an aggregate of 15% of the Public Shares without the Company’s prior written consent.

Sponsor HoldCo has agreed (a) to waive its redemption rights with respect to any Founder Shares and Public Shares held by it in connection with the completion of a business combination and (b) not to propose an amendment to the Amended and Restated Memorandum and Articles of Association (i) to modify the substance or timing of the Company’s obligation to redeem 100% of the Public Shares if the Company does not complete a business combination within the Combination Period (as defined below) or (ii) with respect to any other provision relating to shareholders’ rights or pre-initial business combination activity, unless the Company provides the public shareholders with the opportunity to redeem their Public Shares in conjunction with any such amendment and (iii) to waive its rights to liquidating distributions from the Trust Account with respect to the Founder Shares if the Company fails to complete a business combination.

The Company will have until November 13, 2026 (the “Combination Period”) to complete a business combination. If the Company is unable to complete a business combination within the Combination Period, the Company will (i) cease all operations except for the purpose of winding up, (ii) as promptly as reasonably possible but no more than 10 business days thereafter, redeem 100% of the outstanding Public Shares, at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account, including interest earned (less up to $100,000 of interest to pay dissolution expenses and net of taxes payable), divided by the number of then outstanding Public Shares, which redemption will completely extinguish public shareholders’ rights as shareholders (including the right to receive further liquidation distributions, if any), and (iii) as promptly as reasonably possible following such redemption, subject to the approval of the remaining shareholders and the Company’s board of directors, liquidate and dissolve, subject in each case to its obligations under Cayman Islands law to provide for claims of creditors and the requirements of other applicable law.

(UNAUDITED)

Sponsor HoldCo has agreed to waive its liquidation rights with respect to the Founder Shares if the Company fails to complete a business combination within the Combination Period. However, if Sponsor HoldCo acquires Public Shares in or after the Initial Public Offering, such Public Shares will be entitled to liquidating distributions from the Trust Account if the Company fails to complete a business combination within the Combination Period. The underwriter has agreed to waive its rights to its deferred underwriting commission (see Note 6) held in the Trust Account in the event the Company does not complete a business combination within the Combination Period and, in such event, such amounts will be included with the funds held in the Trust Account that will be available to fund the redemption of the Public Shares. In the event of such distribution, it is possible that the per share value of the assets remaining available for distribution will be less than the Initial Public Offering price per Unit ($10.00).

Sponsor HoldCo has agreed that it will be liable to the Company, if and to the extent any claims by a third party for services rendered or products sold to the Company, or by a prospective target business with which the Company has discussed entering into a transaction agreement, reduce the amount of funds in the Trust Account to below (1) $10.00 per Public Share or (2) such lesser amount per Public Share held in the Trust Account as of the date of the liquidation of the Trust Account due to reductions in the value of trust assets, in each case net of the amount of interest which may be withdrawn to pay taxes. This liability will not apply with respect to any claims by a third party who executed a waiver of any and all rights to seek access to the Trust Account nor will it apply to any claims under the Company’s indemnity of the underwriter of the Initial Public Offering against certain liabilities, including liabilities under the Securities Act of 1933, as amended (the “Securities Act”). Moreover, in the event that an executed waiver is deemed to be unenforceable against a third party, Sponsor HoldCo will not be responsible to the extent of any liability for such third-party claims. The Company will seek to reduce the possibility that Sponsor HoldCo will have to indemnify the Trust Account due to claims of creditors by endeavoring to have all vendors, service providers (other than the Company’s independent auditors), prospective target businesses or other entities with which the Company does business, execute agreements with the Company waiving any right, title, interest or claim of any kind in or to monies held in the Trust Account.

On April 29, 2026, the Company convened an extraordinary general meeting of its shareholders (the “Extraordinary General Meeting”) at which shareholders were asked to vote on, among other things, (i) a proposal to amend the Company’s amended and restated memorandum and articles of association to extend the date by which the Company must consummate a business combination from May 13, 2026 to November 13, 2026 (the “Extension Amendment Proposal”), and (ii) a proposal to amend the Investment Management Trust Agreement, dated May 8, 2024, by and between the Company and Continental Stock Transfer & Trust Company, as trustee, to extend the date on which the trustee must liquidate the trust account from May 13, 2026 to November 13, 2026 (the “Trust Amendment Proposal”). At the Extraordinary General Meeting, the only proposal submitted for a vote was the approval of the adjournment of the meeting to permit further solicitation and vote of proxies in connection with the Extension Amendment Proposal and the Trust Amendment Proposal (the “Adjournment Proposal”). The Adjournment Proposal was approved, and the Extraordinary General Meeting was adjourned to May 6, 2026.

On May 1, 2026, Sponsor and the three independent directors of GP-Act III Acquisition Corp. (the “Company”), holding all of the issued and outstanding Class B ordinary shares, par value $0.0001 per share, of the Company (the “Class B ordinary shares”, also referred to as the “Founder Shares”), elected to convert all of their Class B ordinary shares into Class A ordinary shares, par value $0.0001 per share, of the Company (the “Class A ordinary shares”), on a one-for-one basis, in accordance with the amended and restated memorandum and articles of association of the Company (the “Conversion”). As a result, 7,187,500 of the Company’s Class B ordinary shares were cancelled, and 7,187,500 Class A ordinary shares were issued to the Sponsor and the three independent directors.

On May 6, 2026, the Company reconvened the Extraordinary General Meeting. The only proposal submitted for a vote was the Adjournment Proposal, which was approved by the Company’s shareholders. The Extraordinary General Meeting was adjourned to May 12, 2026, to permit further solicitation and vote of proxies in connection with the Extension Amendment Proposal and the Trust Amendment Proposal.

(UNAUDITED)

On May 12, 2026, the Company reconvened the Extraordinary General Meeting, at which holders of 30,864,730 of the Company’s ordinary shares, representing approximately 85.88% of the ordinary shares outstanding and entitled to vote as of the record date, were represented in person or by proxy. The Company’s shareholders approved the Extension Amendment Proposal and the Trust Amendment Proposal, with each proposal receiving 23,799,592 votes in favor, 7,065,138 votes against and no abstentions. In connection with the vote to approve the Extension Amendment Proposal, holders of 19,776,272 Class A ordinary shares properly exercised their right to redeem their shares for cash at a redemption price of approximately $10.89 per share, for an aggregate redemption amount of approximately $215,421,832, leaving approximately $97,750,320 in the Trust Account. In connection with the Extraordinary General Meeting, the Company and Sponsor HoldCo entered into certain Non-Redemption Agreements with certain investors pursuant to which such investors agreed not to redeem, and to vote in favor of, the Extension Amendment Proposal and the Trust Amendment Proposal at the Extraordinary General Meeting with respect to an aggregate of 8,074,387 Class A ordinary shares, in exchange for Sponsor HoldCo’s agreement to transfer an aggregate of 403,720 Class A ordinary shares to such investors promptly following the closing of the Company’s initial business combination.

Liquidity and Going Concern

As of June 30, 2026, the Company had $10,586 in its operating bank account and a working capital deficit of $2,261,875.

The Company has until November 13, 2026 to consummate the initial business combination (assume no extensions). If the Company does not complete a business combination, the Company will trigger an automatic winding up, dissolution and liquidation pursuant to the terms of the Amended and Restated Memorandum and Articles of Association. Notwithstanding management’s belief that the Company will have sufficient funds to execute its business strategy, there remains uncertainty regarding the timing of the consummation of the Business Combination, which may not occur until November 13, 2026.

In connection with the Company’s assessment of going concern considerations in accordance with ASC 205-40, “Going Concern”, as of June 30, 2026, the Company may need to raise additional capital through loans or additional investments from its Sponsor, stockholders, 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.

Management plans to address this uncertainty through a business combination. If a business combination is not consummated by the end of the Combination Period, currently November 13, 2026, there will be a mandatory liquidation and subsequent dissolution of the Company. Management has determined that the liquidity condition, the date of mandatory liquidation and subsequent dissolution raise substantial doubt about the Company’s ability to continue as a going concern. 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.

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, the Israel-Hamas conflict and the military conflict involving the United States, Israel and Iran, including the joint U.S.-Israel military operation against Iran in February 2026 and subsequent retaliatory strikes. 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 Israel-Hamas conflict and the military conflict involving Iran 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 and increased risks of disruption to global energy supply that could have a lasting impact on regional and global economies. Although the length and impact of the conflicts are highly unpredictable, they could lead to market disruptions, including significant volatility in commodity prices, including oil prices, credit and capital markets, as well as supply chain interruptions and increased cyber-attacks 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, the military conflict involving the United States, Israel and Iran 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.

NOTE 2 — SUMMARY OF 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 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 10K as filed with the SEC on March 26, 2026. The interim results for the three and six months ended June 30, 2026, are not necessarily indicative of the results to be expected for the year ending December 31, 2026 or for any future periods.

Use of Estimates

The preparation of unaudited condensed financial statements in conformity with 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 unaudited condensed financial statements and the reported amounts of expenses during the reporting periods.

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 unaudited 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 has $10,586 and $112,660 in cash as of June 30, 2026 and December 31, 2025, respectively. There were no cash equivalents as of June 30, 2026 and December 31, 2025.

Marketable Securities Held in Trust Account

At June 30, 2026 and December 31, 2025, substantially all the assets held in the Trust Account amounting to $98,235,059 and $309,180,211, respectively, were held in money market funds, which are invested primarily in Treasury securities. All of the Company’s marketable securities held in the Trust Account are presented on the accompanying condensed balance sheets at fair value at the end of each reporting period. Gains and losses resulting from the change in fair value of marketable securities held in Trust Account are included in interest earned on marketable securities held in Trust Account in the accompanying condensed statements of operations. The estimated fair values of investments held in the Trust Account are determined using available market information.

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. 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 were charged to temporary equity and offering costs allocated to the Public and Private Placement Warrants were charged to shareholders’ deficit.

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 redemption outside of permanent deficit 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 are the allocated proceeds determined in accordance with ASC 470-20. The Company recognizes changes in redemption value immediately as it occurs 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 June 30, 2026 and December 31, 2025, 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. The Company recognizes changes in redemption value immediately as they occur and adjusts the carrying value of redeemable shares to equal the redemption value at the end of each reporting period. Increases or decreases in the carrying amount of redeemable shares are affected by charges against additional paid in capital (to the extent available) and accumulated deficit.

At June 30, 2026 and December 31, 2025, the Class A ordinary shares subject to redemption reflected in the condensed balance sheets are reconciled in the following table:

Net Income Per Ordinary Share

Net income per ordinary share is computed by dividing net income by the weighted average number of ordinary shares outstanding for the period.

The Company complies with accounting and disclosure requirements of FASB ASC Topic 260, “Earnings Per Share.” Net income per share is computed by dividing net income by the weighted average number of ordinary shares outstanding during the period, excluding ordinary shares subject to forfeiture. Basic and diluted net income per ordinary share for Class A ordinary shares and Class B ordinary shares is calculated by dividing net income per ordinary share attributable to the Company by the weighted average number of Class A ordinary shares and Class B ordinary shares outstanding, allocated proportionally to each class of ordinary shares. This presentation assumes a business combination as the most likely outcome. Accretion associated with the redeemable Class A ordinary shares is excluded from earnings per share as the redemption value approximates fair value.

The following tables reflect the calculation of basic and diluted net income per ordinary share:

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 carry forwards. 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 also clarifies the accounting for uncertainty in income taxes recognized in an enterprise’s financial statement and prescribes a recognition threshold and measurement process for financial statement recognition and measurement of a tax position 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 June 30, 2026 and December 31, 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 subject to income tax examinations by major taxing authorities since inception.

The Company is considered an exempted Cayman Islands Company 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 periods presented.

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 of $250,000. Any loss incurred or lack of access to uninsured funds could have a significant adverse impact on the Company’s financial condition, results of operations and cash flows.

Fair Value Measurements

The Company follows the guidance in ASC 820 for its financial assets and liabilities that are re-measured and reported at fair value at each reporting period, and non-financial assets and liabilities that are re-measured and reported at fair value at least annually.

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 based on our assessment of the assumptions that market participants would use in pricing the asset or liability.

Share-Based Compensation

The Company records share-based compensation in accordance with FASB ASC Topic 718, “Compensation-Share Compensation” (“ASC 718”), guidance to account for its share-based compensation. It defines a fair value-based method of accounting for an employee share option or similar equity instrument. The Company recognizes all forms of share-based payments, including share option grants, warrants and restricted share grants, at their fair value on the grant date, which are based on the estimated number of awards that are ultimately expected to vest. Share-based payments, excluding restricted shares, are valued using a Monte Carlo simulation. Grants of share-based payment awards issued to non-employees for services rendered have been recorded at the fair value of the share-based payment, which is the more readily determinable value.

The sale of the Founder Shares to the Company’s directors and director’s nominees by Sponsor HoldCo is in the scope of FASB ASC Topic 718, “Compensation-Stock Compensation” (“ASC 718”). Under ASC 718, stock-based compensation associated with equity-classified awards is measured at fair value upon the grant date. The fair value of the 75,000 shares granted to the Company’s directors and director nominees was $130,500 or $1.74 per share. The Founder Shares were granted subject to a performance condition (i.e., the occurrence of a business combination). Compensation expense related to the Founder Shares is recognized only when the performance condition is probable of occurrence under the applicable accounting literature in this circumstance. As of June 30, 2026, the Company determined that a business combination is not considered probable, and, therefore, no stock-based compensation expense has been recognized. Stock-based compensation would be recognized at the date a business combination is considered probable (i.e., upon consummation of a business combination) in an amount equal to the number of Founder Shares times the grant date fair value per share (unless subsequently modified) less the amount initially received for the purchase of the Founder Shares.

Warrant Instruments

The Company accounts for the Public 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 warrant instruments under equity treatment at their assigned values.

Recently Issued 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 unaudited condensed 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 unaudited condensed financial statements.

NOTE 3 — INITIAL PUBLIC OFFERING

Pursuant to the Initial Public Offering, the Company sold 28,750,000 Units, which includes the full exercise by the underwriter of their over-allotment option in the amount of 3,750,000 Units, at a purchase price of $10.00 per Unit. Each Unit consists of one Class A ordinary share and one-half of one redeemable warrant (“Public Warrant”). Each whole Public Warrant entitles the holder to purchase one Class A ordinary share at an exercise price of $11.50 per share, subject to adjustment (Note 7).

NOTE 4 — PRIVATE PLACEMENT

On March 7, 2024, the Co-sponsors formed Sponsor HoldCo, through which the Co-sponsors (i) hold their respective founder shares (as defined below) and (ii) purchased Private Placement Warrants.

The Co-Sponsor, GPIAC II, LLC, purchased, through Sponsor HoldCo, an aggregate of 237,500 Private Placement Warrants at a price of $1.00 per warrant ($237,500 in the aggregate) in a private placement that closed simultaneously with the closing of the Initial Public Offering. The Co-Sponsor, IDS III LLC, purchased, through Sponsor HoldCo, an aggregate of 118,750 Private Placement Warrants at a price of $1.00 per warrant ($118,750 in the aggregate) in a private placement that closed simultaneously with the Initial Public Offering. The Co-Sponsor, Boxcar Partners III, LLC, purchased, through Sponsor HoldCo, an aggregate of 118,750 private placement warrants at a price of $1.00 per warrant ($118,750 in the aggregate) in a private placement closed simultaneously with the closing of the Initial Public Offering. Cantor purchased an aggregate of 2,500,000 Private Placement warrants at a price of $1.00 per warrant ($2,500,000 in the aggregate) in a private placement that closed simultaneously with the closing of the Initial Public Offering. The non-managing HoldCo investors purchased, indirectly through the purchase of non-managing Sponsor HoldCo membership interests, 4,025,000 Private Placement Warrants at a price of $1.00 per warrant in a private placement that closed simultaneously with the closing of the Initial Public Offering.

Each Private Placement Warrant is exercisable for one Class A ordinary share at a price of $11.50 per share, subject to adjustment (see Note 7). The proceeds from the sale of the Private Placement Warrants were added to the net proceeds from the Initial Public Offering held in the Trust Account. If the Company does not complete a business combination within the Combination Period, the proceeds from the sale of the Private Placement Warrants held in the Trust Account will be used to fund the redemption of the Public Shares (subject to the requirements of applicable law) and the Private Placement Warrants will expire worthless.

Founder Shares

On November 29, 2020, GP sponsor paid $25,000 to cover certain offering and formation costs of the Company in consideration for 11,500,000 Class B ordinary shares (the “Founder Shares”) issued to GP sponsor. On February 1, 2021, the Company effected a share surrender pursuant to which 4,312,500 Founder Shares were cancelled for no consideration, resulting in an aggregate of 7,187,500 Founder Shares outstanding. All share and per-share amounts have been retroactively restated to reflect the share surrender. On March 22, 2021, GP sponsor transferred 25,000 Founder Shares to each of the four independent directors then serving in such role (an aggregate of 100,000 founder shares) at their original purchase price, which shares were subsequently surrendered by these former directors on December 29, 2023, in connection with the resignation of those independent directors. On March 22, 2021, GP sponsor transferred 3,543,750 Founder Shares to Act III sponsor at their original purchase price. On December 17, 2021, the Company effected a share capitalization with respect to the Class B ordinary shares of 2,395,834 shares thereof, resulting in the Co-sponsors and the Company’s independent directors at the time holding an aggregate of 9,583,334 Founder Shares. On December 29, 2023, the Company effected a share surrender pursuant to which 2,395,834 Class B ordinary shares were canceled, resulting in an aggregate of 7,187,500 Class B ordinary shares outstanding. The Founder Shares included an aggregate of up to 937,500 shares subject to forfeiture by the holders thereof depending on the extent to which the underwriter’s over-allotment option was exercised, so that the number of Founder Shares would collectively represent 20% of the Company’s issued and outstanding shares upon the completion of the Initial Public Offering. On May 13, 2024, as a result of the underwriter’s election to fully exercise its over-allotment option, the 937,500 shares are no longer subject to forfeiture.

Sponsor HoldCo has agreed, subject to limited exceptions, not to transfer, assign or sell any of its Founder Shares until the earlier to occur of: (A) one year after the completion of a business combination; and (B) subsequent to a business combination, (x) if the last reported sale price of the Class A ordinary shares equals or exceeds $12.00 per share (as adjusted for share sub-divisions, share capitalizations, reorganizations, recapitalizations and the like) for any 20 trading days within any 30-trading day period commencing at least 150 days after a business combination, or (y) the date on which the Company completes a liquidation, merger, amalgamation, share exchange, reorganization or other similar transaction that results in all of the Company’s shareholders having the right to exchange their Class A ordinary shares for cash, securities or other property.

On March 7, 2024, GP-Act III Sponsor LLC transferred 75,000 Founder Shares to three directors (25,000 founder shares per director) of the Company, at a price of $0.0034 per share. Each buyer paid $86.96 for an aggregate purchase price of $260.88 in consideration of the assignment of shares. If the director ceases to be a director of the Company for any reason before the consummation of the business combination, at the Sponsor’s election, it will either repurchase the shares at the purchase price or forfeit the share back to the Company for no consideration. The Founder Shares will automatically convert into shares of Class A Ordinary Shares at the time of the business combination on a one-for-one basis, subject to adjustment as described in the Company’s certificate of incorporation. The directors have agreed to the same terms as the initial stockholders whereby subject to certain limited exceptions, not to transfer, assign or sell any of its Founder Shares until the earlier to occur of: (A) one year after the completion of a business combination; and (B) subsequent to a business combination, (x) if the last reported sale price of the Class A ordinary shares equals or exceeds $12.00 per share (as adjusted for share sub-divisions, share capitalizations, reorganizations, recapitalizations and the like) for any 20 trading days within any 30-trading day period commencing at least 150 days after a business combination, or (y) the date on which the Company completes a liquidation, merger, amalgamation, share exchange, reorganization or other similar transaction that results in all of the Company’s shareholders having the right to exchange their Class A ordinary shares for cash, securities or other property.

On May 1, 2026, the Sponsor and three independent directors of the Company, holding all of the issued and outstanding Class B ordinary shares, par value $0.0001 per share, of the Company (the “Class B ordinary shares,” also referred to as the “Founder Shares”), elected to convert all of their Class B ordinary shares into Class A ordinary shares, par value $0.0001 per share, of the Company (the “Class A ordinary shares”), on a one-for-one basis, in accordance with the amended and restated memorandum and articles of association of the Company (the “Conversion”). As a result, 7,187,500 Class B ordinary shares were cancelled and 7,187,500 Class A ordinary shares were issued to the Sponsor and three independent directors. The Sponsor and three independent directors agreed that all of the terms and conditions applicable to the Founder Shares set forth in the Letter Agreement, dated May 8, 2024, by and among the Company, Sponsor and the Company’s officers and directors (the “Letter Agreement”), including the voting agreement, transfer restrictions and the waiver of any right, title, interest or claim in or to any monies held in the trust account, shall continue to apply to the Class A ordinary shares into which the Founder Shares were converted. Following the Conversion, the Company had approximately 35,937,500 Class A ordinary shares issued and outstanding and no Class B ordinary shares issued and outstanding.

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 $1,500,000 of such Working Capital Loans for each such person may be convertible into warrants of the post-business combination entity at a price of $1.00 per warrant. The warrants would be identical to the Private Placement Warrants. As of June 30, 2026 and December 31, 2025, there are no Working Capital Loans outstanding.

Advances from Related Party

At December 31, 2025, the Company reversed $43,625 previously recorded as an advance from a related party, as the amount was not appropriately classified in the original recording. During the year ended December 31, 2025, the Sponsor advanced the Company $1,313 for working capital purposes, of which $0 was repaid during the period ended June 30, 2026. As of June 30, 2026 and December 31, 2025, the outstanding balance under the advances amounted to $1,313.

Due from Sponsor

The Company covered certain expenses on behalf of its Sponsor, paying $5,254 as of June 30, 2026 and December 31, 2025, of which such amount is included in due from sponsor in the accompanying condensed balance sheets.

NOTE 6 — COMMITMENTS AND CONTINGENCIES

Registration Rights

The holders of the Founder Shares, Private Placement Warrants, warrants that may be issued upon conversion of the Working Capital Loans (and any Class A ordinary shares issuable upon the exercise of the Private Placement Warrants and warrants that may be issued upon conversion of Working Capital Loans and upon conversion of the Founder Shares) are entitled to registration rights pursuant to a registration rights agreement to be signed on May 8, 2024 requiring the Company to register such securities for resale (in the case of the Founder Shares, only after conversion to our Class A ordinary shares). The holders of these securities will be entitled to make up to three demands, excluding short form registration demands, that the Company registers such securities. In addition, the holders have certain “piggy-back” registration rights with respect to registration statements filed subsequent to completion of a business combination and rights to require the Company to register for resale such securities pursuant to Rule 415 under the Securities Act. However, the registration rights agreement provides that the Company will not be required to effect or permit any registration or cause any registration statement to become effective until termination of the applicable lock-up period. The registration rights agreement does not contain liquidating damages or other cash settlement provisions resulting from delays in registering the Company’s securities. The Company will bear the expenses incurred in connection with the filing of any such registration statements.

Warrant Agreement Amendments

The warrant agreement provides that (a) the terms of the Public Warrants may be amended without the consent of any holder for the purpose of (i) curing any ambiguity or correcting any mistake, including to conform the provisions of the warrant agreement to the description of the terms of the Public Warrants and the warrant agreement set forth in the prospectus, or defective provision (ii) removing or reducing the Company’s ability to redeem the Public Warrants and, if applicable, a corresponding amendment to the Company’s ability to redeem the Private Placement Warrants or (iii) adding or changing any provisions with respect to matters or questions arising under the warrant agreement as the parties to the warrant agreement may deem necessary or desirable and that the parties deem to not adversely affect the rights of the registered holders of the Public Warrants under the warrant agreement in any material respect, (b) the terms of the warrants may be amended with the vote or written consent of at least 50% of the then outstanding Public Warrants and Private Placement Warrants, voting together as a single class, to allow for the warrants to be, or continue to be, as applicable, classified as equity in the Company’s financial statement and (c) all other modifications or amendments to the Company’s warrant agreement with respect to (i) the Public Warrants require the vote or written consent of holders of at least 50% of the then outstanding Public Warrants and (ii) the Private Placement Warrants require the vote or written consent of holders of at least 50% of the then outstanding Private Placement Warrants (including the vote or written consent of Cantor). Accordingly, the Company may amend the terms of the Public Warrants in a manner adverse to a holder of Public Warrants if holders of at least 50% of the then outstanding Public Warrants approve of such amendment. Although the Company’s ability to amend the terms of the Public Warrants with the consent of at least 50% of the then outstanding Public Warrants is unlimited, examples of such amendments could be amendments to, among other things, increase the exercise price of the warrants, shorten the exercise period or decrease the number of ordinary shares purchasable upon exercise of a warrant.

Underwriting Agreement

The underwriter had a 45-day option from the date of the Initial Public Offering to purchase up to 3,750,000 additional Units to cover the over-allotment. On May 13, 2024, simultaneously with the closing of the Initial Public Offering, the underwriter elected to fully exercise the over-allotment option to purchase the additional 3,750,000 Units at a price of $10.00 per Unit.

The underwriter was entitled to a cash underwriting discount of $0.20 per Unit, or $5,000,000 in the aggregate, and was paid at the closing of the Initial Public Offering. In addition, the underwriter is entitled to a deferred fee of (i) $0.45 per Unit sold in the base offering of the Initial Public Offering, or $11,250,000 in the aggregate, and (ii) $0.65 per Unit sold pursuant to the underwriter’s over-allotment option, or up to an additional $2,437,500 in the aggregate ($13,687,500 in total). The deferred fee will become payable to the underwriter from the amounts held in the Trust Account solely in the event that the Company completes a business combination, subject to the terms of the underwriting agreement.

Deferred Legal Fees

As of June 30, 2026 and December 31, 2025, the Company had a total of $350,000 of deferred legal fees payable to the Company’s legal advisors upon consummation of the business combination, which is included in the accompanying condensed balance sheets as of June 30, 2026 and December 31, 2025.

Advisory Services Agreement

On December 11, 2025, the Company engaged ING Bank N.V., London branch (“ING”) to provide advisory services in connection with the Company’s proposed Business Combination. Pursuant to the agreement, ING is entitled to a success fee payable upon the successful completion of this specific Business Combination. As of June 30, 2026 and December 31, 2025, no amounts have been accrued for this fee.

Non-Redemption Agreements

In connection with the Extraordinary General Meeting, the Company and Sponsor HoldCo entered into certain Non-Redemption Agreements with certain investors pursuant to which such investors agreed not to redeem, and to vote in favor of, the Extension Amendment Proposal and the Trust Amendment Proposal at the Extraordinary General Meeting with respect to an aggregate of 8,074,387 Class A ordinary shares, in exchange for Sponsor HoldCo’s agreement to transfer an aggregate of 403,720 Class A ordinary shares to such investors promptly following the closing of the Company’s initial business combination.

Upon satisfaction of the requirements for the Non-Redemption Agreements, the Sponsor will transfer 403,720 Class A Ordinary Shares to the Non-Redemption Agreements Investors at the close of an initial Business Combination. The expense was measured based on the estimated fair value of 403,720 Class A ordinary shares on the agreement date, using an implied fair value per share of approximately $0.54. The fair value was determined using the probability of a successful Business Combination of 5% and the market trading price of the Class A ordinary shares on the measurement date, adjusted for a probability-weighted discount to reflect the likelihood of completing an initial Business Combination. In association with the Non-Redemption Agreements, the Company is reporting a Non-Redemption Agreements expense on the condensed statement of income of $217,807 and $0 for the three and six months ended June 30, 2026 and 2025, respectively and a corresponding equity contribution from the Non-Redemption Agreements on the condensed statements of changes in shareholders’ deficit.

NOTE 7 — SHAREHOLDERS’ DEFICIT

Preference Shares — The Company is authorized to issue 1,000,000 preference shares with a par value of $0.0001 per share, with such designations, voting and other rights and preferences as may be determined from time to time by the Company’s board of directors. At June 30, 2026 and December 31, 2025, there were no preference shares issued and outstanding.

Class A Ordinary Shares — The Company is authorized to issue 200,000,000 Class A ordinary shares, with a par value of $0.0001 per share. Holders of Class A ordinary shares are entitled to one vote for each share. At June 30, 2026 and December 31, 2025, there were 7,187,500 and 0 Class A ordinary shares issued and outstanding, respectively, excluding 8,973,728 and 28,750,000, respectively, shares subject to possible redemption.

Class B Ordinary Shares — The Company is authorized to issue 20,000,000 Class B ordinary shares, with a par value of $0.0001 per share. Holders of the Class B ordinary shares are entitled to one vote for each share. At June 30, 2026 and December 31, 2025, there were 0 and 7,187,500 Class B ordinary shares issued and outstanding, respectively.

Only holders of Class B ordinary shares have the right to vote on the election of directors prior to the business combination. Holders of Class A ordinary shares and holders of Class B ordinary shares will vote together as a single class on all other matters submitted to a vote of the Company’s shareholders except as otherwise required by law.

The Class B ordinary shares will automatically convert into Class A ordinary shares at the time of a business combination or earlier at the option of the holder, on a one-for-one basis, subject to adjustment. In the case that additional Class A ordinary shares, or equity-linked securities, are issued or deemed issued in excess of the amounts issued in the Initial Public Offering and related to the closing of a business combination, the ratio at which the Class B ordinary shares will convert into Class A ordinary shares will be adjusted (unless the holders of a majority of the issued and outstanding Class B ordinary shares agree to waive such anti-dilution adjustment with respect to any such issuance or deemed issuance) so that the number of Class A ordinary shares issuable upon conversion of all Class B ordinary shares will equal, in the aggregate, on an as-converted basis, 20% of the sum of all ordinary shares issued and outstanding upon the completion of the Initial Public Offering plus all Class A ordinary shares and equity-linked securities issued or deemed issued in connection with a business combination, excluding any shares or equity-linked securities issued, or to be issued, to any seller in a business combination.

Warrants — As of June 30, 2026 and December 31, 2025, there were 21,375,000 Warrants outstanding, including 14,375,000 Public Warrants and 7,000,000 Private Placement Warrants. Public Warrants may only be exercised for a whole number of shares. No fractional shares will be issued upon exercise of the Public Warrants. The Public Warrants will become exercisable on the later of (a) 30 days after the completion of a business combination and (b) 12 months from the closing of the Initial Public Offering. The Public Warrants will expire five years from the completion of a business combination or earlier upon redemption or liquidation.

(UNAUDITED)

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

The Company has agreed that as soon as practicable, but in no event later than 15 business days, after the closing of a business combination, it will use its commercially reasonable efforts to file with the SEC a registration statement covering the issuance, under the Securities Act, of the Class A ordinary shares issuable upon exercise of the warrants, and the Company will use its commercially reasonable efforts to cause the same to become effective within 60 business days after the closing of a business combination and to maintain the effectiveness of such registration statement, and a current prospectus relating thereto, until the expiration of the warrants in accordance with the provisions of the warrant agreement. Notwithstanding the above, if the Class A ordinary shares are, at the time of any exercise of a warrant, not listed on a national securities exchange such that they satisfy the definition of a “covered security” under Section 18(b)(1) of the Securities Act, the Company may, at its option, require holders of Public Warrants who exercise their warrants to do so on a “cashless basis” in accordance with Section 3(a)(9) of the Securities Act and, in the event the Company so elects, the Company will not be required to file or maintain in effect a registration statement, but will use its commercially reasonable efforts to register or qualify the shares under applicable blue sky laws to the extent an exemption is not available.

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

●

in whole and not in part;

●

at a price of $0.01 per Public Warrant;

●

upon not less than 30 days’ prior written notice of redemption to each warrant holder and

●

if, and only if, the closing price of the Class A ordinary shares equals or exceeds $18.00 per share (as adjusted for share sub-divisions, share capitalizations, reorganizations, recapitalizations and the like) 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 warrant holders.

The Company will not redeem the warrants for cash unless a registration statement under the Securities Act covering the issuance of the shares of Class A ordinary shares issuable upon exercise of the warrants is then effective and a current prospectus relating to those Class A ordinary shares is available throughout the 30-day redemption period, unless the warrants may be exercised on a cashless basis and such cashless exercise is exempt from registration under. If and when the warrants become redeemable by the Company, the Company may exercise its redemption right even if the Company is unable to register or qualify the underlying securities for sale under all applicable state securities laws.

If the Company calls the warrants for redemption as described in this paragraph, its management will have the option to require any holder that wishes to exercise his, her or its warrant following the notice of redemption to do so on a cashless basis. In the case of such a cashless exercise, each holder would pay the exercise price by surrendering the Public 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 excess of the “fair market value” less the exercise price of the warrants by (y) the fair market value. The “fair market value” as used in the preceding sentence shall mean the volume weighted average price of the Class A ordinary shares for the 10 trading days ending on the trading day prior to the date on which the notice of redemption is sent to the holders of the public warrants. If its management takes advantage of this option, the notice of redemption will contain the information necessary to calculate the number of shares of Class A ordinary shares to be received upon exercise of the warrants, including the “fair market value” in such case.

The Company has established the $18.00 per share (as adjusted) redemption criterion discussed above to prevent a redemption call unless there is at the time of the call a significant premium to the public warrant exercise price. If the foregoing conditions are satisfied and the Company issues a notice of redemption of the Public Warrants, each Public Warrant holder will be entitled to exercise his, her or its Public Warrant prior to the scheduled redemption date. However, the price of the Class A ordinary shares may fall below the $18.00 redemption trigger price as well as the $11.50 Public Warrant exercise price after the redemption notice is issued.

In addition, if (x) the Company issues additional ordinary shares or equity-linked securities for capital raising purposes in connection with the closing of its Initial business combination at an issue price or effective issue price of less than $9.20 per ordinary share (with such issue price or effective issue price to be determined in good faith by its board of directors and, in the case of any such issuance to either of Sponsor HoldCo or its affiliates, without taking into account any Founder Shares held by Sponsor HoldCo 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 its Initial business combination on the date of the completion of its 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 its initial business combination (such price, the “Market Value”) is below $9.20 per share, the exercise price of the public warrants will be adjusted (to the nearest cent) to be equal to 115% of the higher of the Market Value and the Newly Issued Price, the $18.00 per share redemption trigger price 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 Private Placement Warrants are identical to the Public Warrants underlying the Units being sold in the Initial Public Offering, except that the Private Placement Warrants and the Class A ordinary shares issuable upon the exercise of the Private Placement Warrants will not be transferable, assignable or salable until 30 days after the completion of a business combination, subject to certain limited exceptions. Additionally, the Private Placement Warrants will be exercisable on a cashless basis and be non-redeemable.

NOTE 8 — FAIR VALUE MEASUREMENT

NOTE 9 — 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 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 Financial 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 that also is reported on the condensed statements of operations as net income. 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, which include the following:

	June 30, 2026		December 31, 2025
Marketable securities held in Trust Account	$	98,235,059	$	309,180,211
Cash	$	10,586	$	112,660

	For the three months ended June 30, 2026		For the three months ended June 30, 2025		For the six months ended June 30, 2026		For the six months ended June 30, 2025
General and administrative expenses	$	1,250,095	$	141,334	$	1,815,374	$	341,386
Interest earned on marketable securities held in Trust Account	$	1,758,023	$	3,126,072	$	4,476,680	$	6,233,453

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 or similar transaction 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.

The accounting policies used to measure the profit and loss of the segment are the same as those described in the summary of significant accounting policies.

NOTE 10 — SUBSEQUENT EVENTS

Based upon this review, the Company did not identify any subsequent events that would have required adjustment or disclosure in the unaudited condensed financial statements.

Overview

We are a blank check company incorporated in the Cayman Islands on November 23, 2020, formed for the purpose of effecting a merger, amalgamation, share exchange, asset acquisition, share purchase, reorganization or similar business combination with one or more businesses that we have not yet identified. 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 warrants, 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.

Results of Operations

We have neither engaged in any operations nor generated any revenues to date. Our only activities from November 23, 2020 (inception) through June 30, 2026 were organizational activities, those necessary to prepare for the Initial Public Offering, described below, and subsequent to the Initial Public Offering, identifying a target company for a business combination. We do not expect to generate any operating revenues until after the completion of our business combination. We generate non-operating income in the form of interest income from the proceeds derived from the Initial Public Offering 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 June 30, 2026, we had a net income of $290,121, which consisted of interest earned on marketable securities held in the Trust Account of $1,758,023, partially offset by formation and operational costs of $1,467,902.

For the three months ended June 30, 2025, we had a net income of $2,984,738, which consisted of interest earned on marketable securities held in the Trust Account of $3,126,072, partially offset by formation and operational costs of $141,334.

For the six months ended June 30, 2026, we had a net income of $2,443,499, which consisted of interest earned on marketable securities held in the Trust Account of $4,476,680, partially offset by formation and operational costs of $2,033,181.

For the six months ended June 30, 2025, we had a net income of $5,892,067, which consisted of interest earned on marketable securities held in the Trust Account of $6,233,453, partially offset by formation and operational costs of $341,386.

Liquidity and Capital Resources

Until the consummation of the Initial Public Offering, our only source of liquidity was an initial purchase of shares of Class B ordinary shares, par value $0.0001 per share, by our co-sponsors in the amount of $25,000 and loans from our co-sponsors or their affiliates pursuant to promissory notes. These loans are non-interest bearing, unsecured and are due at the earlier of the consummation of our initial business combination and the second anniversary of the consummation of our Initial Public Offering. As of June 30, 2026, there was a total amount of $595,000 outstanding under such promissory notes, of which $260,000 remains outstanding under the promissory note with GP Sponsor, $205,000 remains outstanding under the promissory note with Boxcar Partners Two, LLC, an affiliate of Boxcar sponsor, and $130,000 remains outstanding under the promissory note with Act III sponsor. As of December 31, 2025, there was a total amount of $400,000 outstanding under such promissory notes, of which $200,000 remains outstanding under the promissory note with GP Sponsor, $100,000 remains outstanding under the promissory note with Boxcar Partners Two, LLC, an affiliate of Boxcar sponsor, and $100,000 remains outstanding under the promissory note with Act III sponsor.

On May 13, 2024, we consummated the Initial Public Offering of 28,750,000 Units, which includes the full exercise by the underwriter of its over-allotment option in the amount of 3,750,000 Units, at $10.00 per Unit, generating gross proceeds of $287,500,000. Simultaneously with the closing of the Initial Public Offering, we consummated the sale of 7,000,000 private placement warrants to Sponsor HoldCo and to Cantor at a price of $1.00 per Private Placement Warrant, generating gross proceeds of $7,000,000, including the purchase by the non-managing HoldCo investors, indirectly through the purchase of non-managing Sponsor HoldCo membership interests, if 4,025,000 private placement warrants at a price of $1.00 per warrant.

Following the Initial Public Offering and the private placement, a total of $287,500,000 ($10.00 per Unit) was placed in the Trust Account. We incurred transaction costs of $20,269,166 consisting of $5,000,000 of cash underwriting fee, $13,687,500 of deferred underwriting fee (see additional discussion in Note 6 of the financial statements), and $1,581,666 of other offering costs.

For the six months ended June 30, 2026, cash used in operating activities was $297,074. Net income of $2,443,499 was affected by interest earned on marketable securities held in the Trust Account of $4,476,680 and non-redemption agreement expense of $217,807. Changes in operating assets and liabilities provided $1,518,300 of cash for operating activities.

For the six months ended June 30, 2025, cash used in operating activities was $282,196. Net income of $5,892,067 was affected by interest earned on marketable securities held in the Trust Account of $6,233,453. Changes in operating assets and liabilities used $59,190 of cash for operating activities.

As of June 30, 2026, we had marketable securities held in the Trust Account of $98,235,059 (including approximately $26,156,891 of interest income). 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 permitted withdrawals and deferred underwriting discounts and commissions), to complete our initial business combination. To the extent that our capital stock or debt is used, in whole or in part, as consideration to complete our initial 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 June 30, 2026, we had cash of $10,586. 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, structure, negotiate and complete a business combination, and to pay for directors and officers liability insurance premiums. We have incurred and expect to continue to incur significant professional costs to remain as a publicly traded company and to incur significant transaction costs in pursuit of the consummation of a business combination.

We have until November 13, 2026 to consummate the initial business combination. If we do not complete a business combination, we will trigger an automatic winding up, dissolution and liquidation pursuant to the terms of the Amended and Restated Memorandum and Articles of Association. Notwithstanding management’s belief that we would have sufficient funds to execute its business strategy, there is a possibility that business combination might not happen until November 13, 2026.

In connection with our assessment of going concern considerations in accordance with ASC 205-40, “Going Concern”, as of June 30, 2026, we may need to raise additional capital through loans or additional investments from our co-sponsors, Sponsor HoldCo, stockholders, officers, directors, or third parties. Our officers, directors and co-sponsors may, but are not obligated to, loan us funds, from time to time or at any time, in whatever amount they deem reasonable in their sole discretion, to meet our working capital needs. Accordingly, we may not be able to obtain additional financing. If we are 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. We cannot provide any assurance that new financing will be available to it on commercially acceptable terms, if at all.

Off-Balance Sheet Arrangements

We have no obligations, assets or liabilities, which would be considered off-balance sheet arrangements as of June 30, 2026. 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 an aggregate of $5,000 per month to the affiliate of GPIAC II, LLC for office space, administrative and support services. We began incurring these fees on May 8, 2024 and will continue to incur these fees monthly until the earlier of the completion of the business combination and our liquidation.

The underwriter is entitled to a deferred fee of (i) $0.45 per Unit sold in the base offering of the Initial Public Offering, or $11,250,000 in the aggregate, and (ii) $0.65 per Unit sold pursuant to the underwriter’s over-allotment option, or up to an additional $2,437,500 in the aggregate ($13,687,500 in total). Considering that the underwriter’s over-allotment option was exercised in full, the deferred underwriter’s fee of $13,687,500 will become payable to the underwriter from the amounts held in the Trust Account solely in the event that the Company completes an initial business combination subject to the terms of the underwriting agreement.

Critical Accounting Estimates and Standards

The preparation of the condensed financial statements and notes thereto included elsewhere in this Report in conformity with GAAP requires Management to make estimates and assumptions that affect the reported amounts of assets and liabilities, income and expenses, and the disclosure of contingent assets and liabilities, in our financial statements. These accounting estimates require the use of assumptions about matters, some of which are highly uncertain at the time of estimation. Management bases its estimates on historical experience and on various other assumptions it believes to be reasonable under the circumstances, the results of which form the basis for making judgments, and we evaluate these estimates on an ongoing basis. To the extent actual experience differs from the assumptions used, our condensed financial statements and notes thereto included elsewhere in this Report could be materially affected. We believe that the following accounting policies involve a higher degree of judgment and complexity. Using a Black Sholes valuation, the Company evaluated and classified the warrant instruments under equity treatment at their assigned values. Other than estimating the value of the Public Warrants, we did not have any other critical accounting estimates as of June 30, 2026.

Warrant Instruments

We accounted for the Public and 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”, whereby under that provision, the warrants that do not meet the criteria for equity treatment must be recorded as liability. Accordingly, we evaluated and classified the warrant instruments under equity treatment at their assigned value. Such guidance provides that the warrants described above will not be precluded from equity classification. Equity-classified contracts are initially measured at fair value (or allocated value). Subsequent changes in fair value are not recognized as long as the contracts continue to be classified in equity in accordance with ASC 480 and ASC 815.

Class A Ordinary Shares Subject to Possible Redemption

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’ equity. 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, ordinary shares subject to possible redemption are presented at redemption value as temporary equity, outside of the shareholders’ equity section of our condensed balance sheets.

Net Income per Ordinary Share

We comply with accounting and disclosure requirements of ASC 260, Earnings Per Share. We have two classes of shares, which are referred to as Class A ordinary shares and Class B ordinary shares. Income and losses are shared pro rata between the two classes of shares. Net income per ordinary share is calculated by dividing the net income by the weighted average ordinary shares outstanding for the respective period. Diluted net income per share attributable to ordinary shareholders adjust the basic net income per share attributable to ordinary shareholders and the weighted-average ordinary shares outstanding for the potentially dilutive impact of outstanding warrants. However, because the warrants are anti-dilutive, diluted income per ordinary share is the same as basic income per ordinary share for the periods presented.

Recent Accounting Standards

Management does not believe that any recently issued, but not yet effective, accounting standards, if currently adopted, would have a material effect on the Company’s condensed financial statements.

Item 3. Quantitative and Qualitative Disclosures about Market Risk

We are a smaller reporting company as defined by Rule 12b-2 of the Exchange Act and are not required to provide the information otherwise required under this item.

Item 4. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

Disclosure controls and procedures are designed to ensure that information required to be disclosed by us in our Exchange Act reports is recorded, processed, summarized, and reported within the time periods specified in the SEC’s rules and forms, and that such information is accumulated and communicated to our management, including our principal executive officer and principal financial officer 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 principal executive officer and principal financial and accounting officer, we conducted an evaluation of the effectiveness of our disclosure controls and procedures as of the end of the fiscal quarter ended June 30, 2026, as such term is defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act. Based on this evaluation, our principal executive officer and principal financial and accounting officer have concluded that during the period covered by this report, our disclosure controls and procedures were effective at a reasonable assurance level and, accordingly, provided reasonable assurance that the information required to be disclosed by us in reports filed under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms.

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 2026 covered by this Quarterly Report that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

PART II - OTHER INFORMATION

Item 1. Legal Proceedings

None.

Item 1A. Risk Factors

Factors that could cause our actual results to differ materially from those in this Quarterly Report are any of the risks described in our Annual Report on Form 10-K filed with the SEC on March 26, 2026. Any of these factors could result in a significant or material adverse effect on our results of operations or financial condition. Additional risk factors not presently known to us or that we currently deem immaterial may also impair our business or results of operations. As of the date of this Quarterly Report, there have been no material changes to the risk factors disclosed in our Annual Report on Form 10-K filed with the SEC, except we may disclose changes to such factors or disclose additional factors from time to time in our future filings with the SEC.

Item 2. Unregistered Sales of Equity Securities and Use of Proceeds.

On May 13, 2024, we consummated the Initial Public Offering of 28,750,000 units, which includes the full exercise by the underwriter of its over-allotment option in the amount of 3,750,000 Units, at $10.00 per Unit, generating gross proceeds of $287,500,000. Each Unit consists of one Class A ordinary share, and one-half 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. Each warrant 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, or earlier upon redemption or liquidation.

Simultaneously with the closing of the Initial Public Offering, the Sponsor Hold Co and Cantor purchased an aggregate of 7,000,000 Private Placement Warrants at a price of $1.00 per Private Placement Warrant in a private placement. Each Private Placement Warrant entitles the holder to purchase one Class A ordinary share at a price of $11.50 per shares, subject to adjustments.

We incurred transaction costs amounting to $20,269,166 consisting of $5,000,000 of cash underwriting fee, $13,687,500 of deferred underwriting fee, and $1,581,666 of other offering costs.

After deducting the underwriting fees (excluding the deferred portion of $13,687,500, which amount will be payable upon consummation of our initial Business Combination, if consummated) and the offering expenses, the total net proceeds from the Initial Public Offering and the Private Placement was $287,918,334 of which $287,500,000 was placed in the Trust Account.

For a description of the use of the proceeds generated in the Initial Public Offering, see Part I, Item 2 of this Quarterly Report.
