**M3-BRIGADE ACQUISITION V CORP.**

**NOTES TO CONDENSED FINANCIAL STATEMENTS**

**SEPTEMBER 30, 2025**

**(Unaudited)**

**NOTE 1. DESCRIPTION OF ORGANIZATION AND BUSINESS OPERATIONS**

M3-Brigade Acquisition V Corp. (the "Company") is a blank check company incorporated as a Cayman Islands exempted corporation on March 12, 2024. The Company was incorporated for the purpose of effecting a merger, share exchange, asset acquisition, share purchase, reorganization or similar business combination with one or more businesses (the "Business Combination").

As of September 30, 2025, the Company had not commenced any operations. All activity for the period from March 12, 2024 (inception) through September 30, 2025 relates to the Company's formation, the initial public offering ("Initial Public Offering"), which is described below, and the search for a Business Combination, which is described below and in Note 6. The Company will not generate any operating revenues until after the completion of its initial Business Combination, at the earliest. The Company will generate non-operating income in the form of interest income on investments 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 July 31, 2024. On August 2, 2024, the Company consummated the Initial Public Offering of 28,750,000 units (the "Units"), which includes the full exercise by the underwriters of their over-allotment option in the amount of 3,750,000 Units, at $10.00 per Unit, generating gross proceeds of $287,500,000, which is described in Note 3.

Simultaneously with the closing of the Initial Public Offering, the Company consummated the sale of 8,337,500 warrants (the "Private Placement Warrants") to the Original Sponsor (as defined below) and Cantor Fitzgerald & Co. at a price of $1.00 per warrant, or $8,337,500, which is described in Note 4 (the "Private Placement"). Of those 8,337,500 Private Placement Warrants, the Original Sponsor purchased 5,043,750 Private Placement Warrants and Cantor Fitzgerald & Co. purchased 3,293,750 Private Placement Warrants. Each whole warrant entitles the holder to purchase one Class A ordinary share at a price of $11.50 per share. Certain institutional investors who are not affiliated with any member of management, the Original Sponsor or any other investor in the Original Sponsor provided approximately 50.1% of the capital utilized by the Original Sponsor to purchase the Private Placement Warrants and, as a result, indirectly hold approximately 50.1% of such warrants.

Transaction costs relating to the Initial Public Offering amounted to $19,406,996, consisting of $5,000,000 of cash underwriting fees, $13,400,000 of deferred underwriting fees (see additional discussion in Note 6), and $1,006,996 of other offering costs.

The Company's former sponsor is M3-Brigade Sponsor V LLC, a Delaware limited liability company (the "Original Sponsor"), formerly known as M3-Brigade Sponsor V LP, a Delaware limited partnership. On May 23, 2025, the Company entered into a Securities Purchase Agreement (the "Securities Purchase Agreement") with the Original Sponsor and MI7 Sponsor, LLC, a Delaware limited liability company (the "Sponsor"), pursuant to which the Original Sponsor agreed to sell, and the Sponsor agreed to purchase, 7,187,500 Class B ordinary shares, par value $0.0001 per share, and 5,043,750 Private Placement Warrants of the Company owned by the Original Sponsor (collectively, the "Transferred Sponsor SPAC Securities") for an aggregate purchase price of $6,467,500 (the "Closing Cash Purchase Price"). The transactions contemplated by the Agreement were consummated on May 27, 2025 (the "Closing"). At the Closing, the Original Sponsor delivered to the Sponsor an assignment of the Transferred Sponsor SPAC Securities against payment of the Closing Cash Purchase Price.

Also on May 27, 2025, the Sponsor entered into an agreement to purchase 3,293,750 additional Private Placement Warrants of the Company from Cantor Fitzgerald & Co. (the "Cantor Warrants") for an aggregate purchase price of $10, which was consummated on May 27, 2025, upon which Cantor Fitzgerald & Co. delivered to the Sponsor an assignment of the Cantor Warrants.

The Company's Business Combination must be with one or more target businesses that together have a fair market value equal to at least 80% of the net balance in the Trust Account (as defined below) (excluding the amount of deferred underwriting discounts held and taxes payable on the interest earned on the Trust Account) at the time of the signing an agreement to enter into a Business Combination. However, the Company will only complete a Business Combination if the post-Business Combination company owns or acquires 50% or more of the outstanding voting securities of the target or otherwise acquires a controlling interest in the target 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 August 2, 2024, an amount of $288,937,500 ($10.05 per Unit) from the net proceeds of the sale of the Units and the sale of the Private Placement Warrants was placed in the trust account (the "Trust Account"), which may only be held as cash or invested in (i) U.S. government treasury obligations with a maturity of 185 days or less or in money market funds meeting certain conditions under Rule 2a-7 under the Investment Company Act, which invest only in direct U.S. government treasury obligations or (ii) an interest bearing bank demand deposit account or other accounts at a bank. Except with respect to interest earned on the funds held in the Trust Account that may be released to the Company to pay its taxes, if any, the proceeds from the Initial Public Offering and the sale of the Private Placement Warrants will not be released from the Trust Account until the earliest of (i) the completion of the Company's initial Business Combination, (ii) the redemption of the Company's public shares if the Company is unable to complete the initial Business Combination within 24 months from the closing of the Initial Public Offering or by such earlier liquidation date as the board of directors may approve (the "Completion Window"), subject to applicable law, or (iii) the redemption of the Company's public shares properly submitted in connection with a shareholder vote to amend the Company's amended and restated memorandum and articles of association to (A) modify the substance or timing of the Company's obligation to allow redemption in connection with the initial Business Combination or to redeem 100% of the Company's public shares if the Company has not consummated an initial Business Combination within the Completion Window or (B) with respect to any other material provisions relating to shareholders' rights or pre-initial Business Combination activity. The proceeds deposited in the Trust Account could become subject to the claims of the Company's creditors, if any, which could have priority over the claims of the Company's public shareholders.

The Company will provide the Company's public shareholders with the opportunity to redeem all or a portion of their public shares upon the completion of the initial Business Combination either (i) in connection with a general meeting called to approve the initial Business Combination or (ii) without a shareholder vote by means of a tender offer. The decision as to whether the Company will seek shareholder approval of a proposed initial Business Combination or conduct a tender offer will be made by the Company, solely in its discretion. The public shareholders will be entitled to redeem their shares at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account calculated as of two business days prior to the consummation of the initial Business Combination, including interest earned on the funds held in the Trust Account (less taxes payable), divided by the number of then outstanding public shares, subject to the limitations. The amount initially placed in the Trust Account upon the closing of the Initial Public Offering was $10.05 per public share.

The ordinary shares subject to redemption were recorded at their redemption value and classified as temporary equity upon the completion of the Initial Public Offering on August 2, 2024, in accordance with Financial Accounting Standards Board ("FASB") Accounting Standards Codification ("ASC") Topic 480, "Distinguishing Liabilities from Equity." In the event the Company seeks shareholder approval for the Business Combination, the transaction would require a majority of the issued and outstanding shares voted to be in favor of the Business Combination.

The Company will have only the duration of the Completion Window to complete the initial Business Combination. However, if the Company is unable to complete its initial Business Combination within the Completion Window, the Company will cease all operations except for the purpose of winding up and, as promptly as reasonably possible but not more than ten business days thereafter, redeem the public shares, at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account, including interest earned on the funds held in the Trust Account (less taxes payable and up to $100,000 of interest to pay dissolution expenses), divided by the number of then outstanding public shares, which redemption will constitute full and complete payment for the public shares and completely extinguish public shareholders' rights as shareholders (including the right to receive further liquidation or other distributions, if any), subject to the Company's obligations under Cayman Islands law to provide for claims of creditors and subject to the other requirements of applicable law.

The Original Sponsor, officers and directors have entered into a letter agreement (the "Letter Agreement") with the Company, pursuant to which they have agreed to (i) waive their redemption rights with respect to their founder shares and public shares in connection with the completion of the initial Business Combination or an earlier redemption in connection with the commencement of the procedures to consummate the initial Business Combination if the Company determines it is desirable to facilitate the completion of the initial Business Combination; (ii) waive their redemption rights with respect to their founder shares and public shares in connection with a shareholder vote to approve an amendment to the Company's amended and restated memorandum and articles of association (A) to modify the substance or timing of the Company's obligation to allow redemption in connection with its Initial Business Combination or to redeem 100% of the Company's public shares if it has not consummated an Initial Business Combination within the Completion Window or (B) with respect to any other material provisions relating to shareholders' rights or pre-Initial Business Combination activity; (iii) waive their rights to liquidating distributions from the Trust Account with respect to their founder shares if the Company fails to complete the initial Business Combination within the Completion Window, although they will be entitled to liquidating distributions from the Trust Account with respect to any public shares they hold if the Company fails to complete the initial Business Combination within the Completion Window and to liquidating distributions from assets outside the Trust Account; and (iv) vote any founder shares held by them and any public shares purchased during or after the Initial Public Offering (including in open market and privately negotiated transactions) in favor of the initial Business Combination.

Pursuant to the Letter Agreement, the Original Sponsor 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 (except for the Company's independent auditors), or a prospective target business with which the Company has entered into a written letter of intent, confidentiality or other similar agreement or Business Combination agreement (except for the Company's independent auditors), reduce the amount of funds in the Trust Account to below the lesser of (i) $10.05 per public share and (ii) the actual amount per public share held in the Trust Account as of the date of the liquidation of the Trust Account, if less than $10.05 per share due to reductions in the value of the trust assets, less taxes payable, provided that such liability will not apply to any claims by a third party or prospective target business who executed a waiver of any and all rights to the monies held in the Trust Account (whether or not such waiver is enforceable) nor will it apply to any claims under the Company's indemnity of the underwriters of the Initial Public Offering against certain liabilities, including liabilities under the Securities Act of 1933, as amended (the "Securities Act"). However, the Company has not asked the Original Sponsor to reserve for such indemnification obligations, nor has the Company independently verified whether the Original Sponsor has sufficient funds to satisfy its indemnity obligations and the Company believes that the Original Sponsor's only assets are securities of the Company. Therefore, the Company cannot assure that the Original Sponsor would be able to satisfy those obligations.

Pursuant to the Securities Purchase Agreement, on May 27, 2025, the Company entered into an Assignment and Assumption Agreement with the Sponsor, the Original Sponsor and the Company's directors and executive officers, pursuant to which the Original Sponsor assigned to the Sponsor, and the Sponsor assumed, all of the Original Sponsor's rights, title and interests under the Letter Agreement, and the Sponsor agreed to be bound by all terms, conditions, and covenants and be entitled to all the terms and provisions therein.

***Proposed Business Combination***

*Business Combination Agreement*

 

On July 7, 2025, the Company, ReserveOne, Inc., a Delaware corporation ("ReserveOne"), ReserveOne Holdings, Inc., a Delaware corporation and wholly-owned subsidiary of ReserveOne ("Pubco"), R1 SPAC Merger Sub, Inc., a Delaware corporation and a wholly-owned subsidiary of Pubco ("SPAC Merger Sub"), and R1 Company Merger Sub, Inc., a Delaware corporation and a wholly-owned subsidiary of Pubco ("Company Merger Sub" and, together with the SPAC Merger Sub, the "Merger Subs"), entered into a business combination agreement (the "Business Combination Agreement").

As a result of the transactions contemplated by the Business Combination Agreement, the Company will be de-registered in the Cayman Islands and register by way of continuation to the State of Delaware and domesticate as a Delaware corporation (the "Domestication").

Following the Domestication, SPAC Merger Sub will merge with and into the Company (the "SPAC Merger"), with the Company continuing as the surviving entity (the "SPAC Surviving Subsidiary"), and as a result of which the Company will be a wholly-owned subsidiary of Pubco. Promptly following the SPAC Merger, Company Merger Sub will merge with and into ReserveOne (the "Company Merger" and, together with the SPAC Merger, the "Mergers"), with ReserveOne continuing as the surviving company (the "Company Surviving Subsidiary"), and as a result of which ReserveOne will be a wholly-owned subsidiary of Pubco.

As a result of the Mergers, Pubco will become a publicly traded company, all upon the terms and subject to the conditions set forth in the Business Combination Agreement and in accordance with applicable laws.

The shares of Pubco Class A common stock, par value $0.0001 per share, will be listed for trading and will be freely transferable, subject to the transfer restrictions set forth in the sponsor support agreement entered into by the Company, Pubco and the Sponsor in connection with the Business Combination (the "Sponsor Support Agreement") and the lock-up agreement to be entered into by Pubco, the parent company of the Sponsor, CC MI7 SPV, LLC (the "Sponsor Parent") and MI7 Founders, LLC ("MI7 Holder")(the "Lock-Up Agreement") and any restrictions pursuant to applicable laws. The shares of Pubco Class B common stock, par value $0.0001 per share, will not be listed or freely transferable.

The Closing is expected to occur in the first quarter of 2026, subject to the satisfaction of certain customary closing conditions.

*Equity PIPE Subscription Agreement*

Contemporaneously with the execution of the Business Combination Agreement, on July 7, 2025, certain investors (the "Equity PIPE Investors") entered into subscription agreements (collectively, the "Equity PIPE Subscription Agreements") with ReserveOne, Pubco, and solely with respect to Section 8(u) thereof, the Company, pursuant to which the Equity PIPE Investors agreed to purchase up to an aggregate of $500,000,000 of (a) either (i) ReserveOne Common Shares or (ii) in the event the issuance of ReserveOne Common Shares would, in the opinion of the Company, ReserveOne or Pubco on the advice of any of their respective legal counsel, adversely affect the treatment of the Transactions under Section 351 of the Internal Revenue Code of 1986 (the "Code"), shares Pubco Class A common stock (the "Equity PIPE Shares") and (b) either (i) ReserveOne Warrants or (ii) in the event the issuance of ReserveOne Warrants would, in the opinion of the Company, ReserveOne or Pubco and on the advice of their respective legal counsel, adversely affect the treatment of the Transactions under Section 351 of the Internal Revenue Code of 1986, Pubco Warrants ("PIPE Warrants" and, together with the Equity PIPE Shares, the "Equity PIPE Securities") at an aggregate purchase price of $10.00, which $10.00 will entitle Equity PIPE Investors to one Equity PIPE Share and one PIPE Warrant, in a private placement (the "Equity PIPE"). The PIPE Warrants (and the shares underlying the PIPE Warrants, the "Warrant Shares") will be issued pursuant to a Warrant Agreement by and among ReserveOne, Pubco and Continental Stock Transfer & Trust Company, as warrant agent (the "Warrant Agreement"). The Equity PIPE Investors are permitted, under the Equity PIPE Subscription Agreements, to satisfy their commitments thereunder if they hold Company Class A ordinary shares that qualify as Non-Redeemed Shares (as defined in the PIPE Subscription Agreement) by delivering written notice to the Company of its election to fulfill its commitment thereby, subject to certain conditions and restrictions set forth in the Equity PIPE Subscription Agreements. The purchase price for the Equity PIPE Securities may be paid in either cash or Bitcoin, at the sole election of each of the Equity PIPE Investors.

The net proceeds of the Equity PIPE will be converted into Bitcoin, subject to the terms of the Business Combination Agreement (after giving effect to any exceptions therein with respect to payment of any operating expenses and the payment of any expenses related to the consummation of the Business Combination).

The closing of the Equity PIPE is contingent upon the satisfaction of all closing conditions to consummate the Transactions and the Equity PIPE Investors' consent to any amendments, modifications or waivers to the terms of the Business Combination Agreement that would reasonably be expected to materially and adversely affect the economic benefits of the Equity PIPE Investors, among other customary closing conditions.

Pursuant to the Equity PIPE Subscription Agreements, the Company and Pubco have agreed to use commercially reasonable efforts to cause the Equity PIPE Securities and Warrant Shares to be registered on the Registration Statement. To the extent that any Equity PIPE Securities and Warrant Shares are unable to be included on the Registration Statement, Pubco has agreed to register and maintain the registration of the Equity PIPE Securities and Warrant Shares by filing a resale registration statement with the SEC within 30 calendar days after the Closing (at Pubco's sole cost and expense), to register the resale of the Equity PIPE Securities and Warrant Shares. Pubco has agreed to use its commercially reasonable efforts to have such resale registration statement declared effective as soon as practicable after the filing thereof, but no later than 60 calendar days after the Closing, which may be extended an additional 30 calendar days depending on whether the SEC issues comments on the resale registration statement.

Each Equity PIPE Subscription Agreement will terminate and be void and of no further force and effect, subject to certain exceptions, upon the earliest to occur of (i) such date and time as the Business Combination Agreement is terminated in accordance with its terms; (ii) the mutual written agreement of the respective parties to terminate such agreement; or (iii) July 7, 2026.

*Convertible Note Subscription Agreement*

Contemporaneously with the execution of the Business Combination Agreement, on July 7, 2025, certain investors entered into subscription agreements (the "Convertible Notes Subscription Agreements" and such investors, the "Convertible Notes Investors") with Pubco, and, solely with respect to Section 9(t) thereof, the Company, pursuant to which the Convertible Notes Investors have agreed to purchase up to $250,000,000 in aggregate principal amount of Pubco's 1.00% Convertible Senior Notes (the "Convertible Notes" and such subscriptions, including the purchase of any Option Convertible Notes (as defined below), the "Convertible Notes PIPE," and together with the Equity PIPE, the "PIPE Investments"), upon the terms and subject to the conditions set forth therein. In addition, for a period of 30 days following the execution of the Convertible Notes Subscription Agreements, Pubco granted the Convertible Notes Investors an option to purchase additional convertible notes in an aggregate principal amount of up to $50 million, on a pro rata basis based on such Convertible Notes Investor's subscription for Initial Convertible Notes (the "Option Convertible Notes"). None of the Convertible Notes Investors exercised their option to purchase the Option Convertible Notes.

The net proceeds of the Convertible Notes PIPE will be converted into Bitcoin.

The closing of the Convertible Notes PIPE is contingent upon the satisfaction of all closing conditions to consummate the Transactions and the Convertible Notes Investors' consent to any amendments, modifications or waivers to the terms of the Business Combination Agreement that would reasonably be expected to materially and adversely affect the economic benefits of the Convertible Notes Investors, among other customary closing conditions.

Pursuant to the Convertible Notes Subscription Agreements, Pubco has agreed to register and maintain the registration of the Pubco Class A Common Shares issuable upon conversion of the Convertible Notes by filing a resale registration statement with the SEC within 30 calendar days after the Closing (at Pubco's sole cost and expense), to register the resale of the Pubco Class A Common Shares. Pubco has agreed to use its commercially reasonable efforts to have such resale registration statement declared effective as soon as practicable after the filing thereof, but no later than 60 calendar days after the Closing, which may be extended an additional 30 calendar days depending on whether the SEC issues comments on the resale registration statement.

Concurrently with the consummation of the transactions contemplated by the Business Combination Agreement, the Company, Pubco, the Sponsor, the Sponsor Parent and the MI7 Holder will enter into a registration rights agreement that will amend and restate the current registration rights agreement entered into at the time of the Company's initial public offering between the Company and the Original Sponsor (the "Amended and Restated Registration Rights Agreement"), pursuant to which Pubco will (i) assume the registration obligations of the Company under such registration rights agreement and (ii) provide registration rights with respect to the resale of the Registrable Securities (as defined the Amended and Restated Registration Rights Agreement) held by the Sponsor, the Sponsor Parent and the MI7 Holder.

***Liquidity and Capital Resources***

 **

As of September 30, 2025, the Company had $1,683,134 in cash and a working capital deficit of $4,264,621. In connection with the Company's assessment of going concern considerations in accordance with ASC 205-40, "Presentation of Financial Statements - Going Concern," management has determined that the Company's liquidity concerns and mandatory liquidation date 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 cannot assure that its plans to consummate an Initial Business Combination will be successful.

On June 16, 2025, the Company issued a promissory note (the "Note") to the Sponsor, pursuant to which the Company can borrow up to an aggregate principal amount of $2,500,000 from the Sponsor. The Note bears no interest and is payable in full upon the consummation of the Company's initial business combination (the "Maturity Date"). A failure to pay the principal on the Maturity Date shall be deemed an event of default, in which case the Note may be accelerated. If the Company does not consummate an initial business combination, the Note will be repaid solely to the extent the Company has funds available outside its trust account established in connection with the Company's initial public offering. On June 18, 2025 and September 19, 2025, the Company borrowed $500,000 and $1,500,000, respectively, under the Note.

On July 16, 2025, the Company and the Sponsor entered into the First Amendment to the Note (the "Note Amendment"), solely to correct a scrivener's error regarding the Sponsor's option to convert up to $1,500,000 of the outstanding unpaid principal balance under the Note into Private Placement Warrants at a purchase price of $1.50 per Private Placement Warrant. Pursuant to the Note Amendment, the purchase price per Private Placement Warrant was corrected to reflect a purchase price of $1.00 per Private Placement Warrant upon conversion under the Note. All other terms of the Note remain unchanged.

The Company may need to raise additional funds, other than any potential borrowings under the Note, in order to fund the expenditures required for operating its business. However, if the estimate of the costs of completing the transactions contemplated by the agreement with respect to an initial Business Combination discussed in Note 6 are less than the actual amount necessary to do so, the Company may have insufficient funds available to operate its business prior to the completion of a Business Combination.

**NOTE 2. SIGNIFICANT ACCOUNTING POLICIES**

***Basis of Presentation***

The accompanying unaudited condensed financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America ("GAAP") for interim financial information and in accordance with the instructions to Form 10-Q and Article 8 of Regulation S-X of the Securities and Exchange Commission ("SEC"). Certain information or footnote disclosures normally included in unaudited condensed financial statements prepared in accordance with GAAP have been condensed or omitted, pursuant to the rules and regulations of the SEC for interim financial reporting. Accordingly, they do not include all the information and footnotes necessary for a complete presentation of financial position, results of operations, or cash flows. In the opinion of management, the accompanying unaudited condensed financial statements include all adjustments, consisting of a normal recurring nature, which are necessary for a fair presentation of the financial position, operating results and cash flows for the periods presented.

 ****

The accompanying unaudited condensed financial statements should be read in conjunction with the Company's Annual Report on Form 10-K as filed with the SEC on March 28, 2025. The interim results for the three and nine months ended September 30, 2025, the three months ended September 30, 2024 and for the period from March 12, 2024 (inception) through September 30, 2024, are not necessarily indicative of the results to be expected for the year ending December 31, 2025 or for any future periods.

***Emerging Growth Company***

The Company is an "emerging growth company," as defined in Section 2(a) of the Securities Act, as modified by the Jumpstart Our Business Startups Act of 2012 (the "JOBS Act"), and it may take advantage of certain exemptions from various reporting requirements that are applicable to other public companies that are not emerging growth companies including, but not limited to, not being required to comply with the auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act of 2002, reduced disclosure obligations regarding executive compensation in its periodic reports and proxy statements, and exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and shareholder approval of any golden parachute payments not previously approved.

Further, Section 102(b)(1) of the JOBS Act exempts emerging growth companies from being required to comply with new or revised financial accounting standards until private companies (that is, those that have not had a Securities Act registration statement declared effective or do not have a class of securities registered under the 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 a standard is issued or revised and it has different application dates for public or private companies, the Company, as an emerging growth company, can adopt the new or revised standard at the time private companies adopt the new or revised standard. This may make comparison of the Company's financial statements with another public company which is neither an emerging growth company nor an emerging growth company which has opted out of using the extended transition period difficult or impossible because of the potential differences in accounting standards used.

***Use of Estimates***

The preparation of the unaudited condensed financial statements in conformity with U.S. GAAP requires the Company's management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the unaudited condensed financial statements and the reported amounts of revenues and 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 had $1,683,134 and $821,188 in cash as of September 30, 2025 and December 31, 2024, respectively. The Company had no cash equivalents as of September 30, 2025 and December 31, 2024.

***Investments Held in Trust Account***

At September 30, 2025 and December 31, 2024, the assets held in the Trust Account, amounting to $303,948,781 and $294,617,243, respectively, were held in mutual funds composed of U.S. treasury securities. Investments in mutual funds are presented on the condensed balance sheets at fair value at the end of each reporting period. 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." Offering costs consisted principally of professional and registration fees that were related to the Initial Public Offering. FASB ASC 470-20, "Debt with Conversion and Other Options," addresses the allocation of proceeds from the issuance of convertible debt into its equity and debt components. The Company applies this guidance to allocate Initial Public Offering proceeds from the Units between Class A ordinary shares and warrants, using the residual method by allocating Initial Public Offering proceeds first to assigned value of the warrants and then to the Class A ordinary shares. The offering costs allocated to the Class A ordinary shares were charged to temporary equity and the offering costs allocated to the Public and Private Placement Warrants were charged to shareholders' deficit as Public and Private Placement Warrants after management's evaluation were accounted for under equity treatment.

***Fair Value of Financial Instruments***

The fair value of the Company's assets and liabilities, which qualify as financial instruments under FASB ASC 820, "Fair Value Measurements and Disclosures," approximates the carrying amounts represented in the condensed balance sheets, primarily due to their short-term nature.

***Convertible Promissory Note – Related Party***

The Company accounts for the promissory note (the "Note") issued on June 16, 2025 to the Sponsor under ASC Topic 470 and is measured at amortized cost. The embedded conversion feature was evaluated under ASC Topic 815 and determined to meet the "own equity" scope exception and therefore bifurcation is not required. No other embedded features require separate recognition. The fair value option under ASC 825 is not permitted. Accordingly, the Note is measured at the amount of cash proceeds received from the holder.

***Income Taxes***

The Company follows the asset and liability method of accounting for income taxes under FASB 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 statement 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.

 ****

The Company accounts for income taxes under ASC 740. ASC 740 prescribes a recognition threshold and a measurement attribute for the financial statement recognition and measurement of tax positions taken or expected to be taken in a tax return. For those benefits to be recognized, a tax position must be more likely than not to be sustained upon examination by taxing authorities. The Company's management determined that the Cayman Islands is the Company's major tax jurisdiction. The Company recognizes accrued interest and penalties related to unrecognized tax benefits as income tax expense. As of September 30, 2025 and December 31, 2024, there were no unrecognized tax benefits and no amounts accrued for interest and penalties. The Company is currently not aware of any issues under review that could result in significant payments, accruals or material deviation from its position. The Company's management does not expect that the total amount of unrecognized tax benefits will materially change over the next twelve months.

The Company is considered to be an exempted Cayman Islands company with no connection to any other taxable jurisdiction and is presently not subject to income taxes or income tax filing requirements in the Cayman Islands or the United States. As such, the Company's tax provision was zero for the periods presented.

***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).

 **

***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.

 ****

***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 instrument under equity treatment at its assigned value.

***Class A 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 Company recognizes changes in redemption value immediately as they occur and will adjust the carrying value of redeemable shares to equal the redemption value at the end of each reporting period. Immediately upon the closing of the Initial Public Offering, the Company recognized the accretion from initial book value to redemption amount value. The change in the carrying value of redeemable shares will result in charges against additional paid-in capital (to the extent available) and accumulated deficit. Accordingly, at September 30, 2025 and December 31, 2024, Class A ordinary shares subject to possible redemption are presented at redemption value as temporary equity, outside of the shareholders' deficit section of the Company's condensed balance sheets.

At September 30, 2025 and December 31, 2024, the Class A ordinary shares subject to redemption reflected in the condensed balance sheets are reconciled in the following table:

***Net (Loss) Income per Ordinary Share***

The Company complies with accounting and disclosure requirements of FASB ASC Topic 260, "Earnings Per Share." The Company has two classes of shares, which are referred to as Class A ordinary shares and Class B ordinary shares, and the Company's income and losses are shared pro rata between the two classes of shares for the three and nine months ended September 30, 2025. For the period from March 12, 2024 (inception) through September 30, 2024, the Company had one class of share outstanding – Class B ordinary shares. Net (loss) income per ordinary share is calculated by dividing the net (loss) income by the weighted average shares of ordinary shares outstanding for the respective period.

**(Unaudited)**

The calculation of diluted net (loss) income per ordinary share does not consider the effect of the warrants to purchase an aggregate of 22,712,500 Class A ordinary shares issued in connection with the Initial Public Offering (including exercise of the over-allotment option) and the Private Placement because their exercise is contingent upon future events. Accretion associated with the redeemable Class A ordinary shares is excluded from earnings per share as the redemption value approximates fair value.

***Concentration of Credit Risk***

Financial instruments that potentially subject the Company to concentrations of credit risk consist of a cash account in a financial institution, which, at times, may exceed the Federal Deposit Insurance Corporation coverage limit of $250,000. Any loss incurred or a lack of access to such funds could have a significant adverse impact on the Company's financial condition, results of operations, and cash flows.

***Recent Accounting Pronouncements***

Management does not believe that any other recently issued, but not effective, accounting standards, 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, on August 2, 2024 the Company sold 28,750,000 Units, which includes the full exercise by the underwriters of their overallotment 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 (the "public shares"), and one-half of one redeemable warrant (the "Public Warrants" and, together with the Private Placement Warrants, the "warrants"). Each whole warrant entitles the holder to purchase one Class A ordinary share at a price of $11.50 per share, subject to adjustment. 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.

 ****

***Warrants***

As of September 30, 2025 and December 31, 2024, there were 22,712,500 warrants outstanding, including 14,375,000 warrants sold as part of the Units in the Initial Public Offering and 8,337,500 Private Placement Warrants. Each whole warrant entitles the holder to purchase one Class A ordinary share at a price of $11.50 per share, subject to adjustment as discussed herein. The warrants cannot be exercised until 30 days after the completion of the initial Business Combination, and will expire at 5:00 p.m., New York City time, five years after the completion of the initial Business Combination or earlier upon redemption or liquidation.

The Company will not be obligated to deliver any Class A ordinary shares pursuant to the exercise of a warrant and will have no obligation to settle such warrant exercise unless a registration statement under the Securities Act with respect to the Class A ordinary shares underlying the warrants is then effective and a prospectus relating thereto is current. No warrant will be exercisable and the Company will not be obligated to issue a Class A ordinary share upon exercise of a warrant unless the Class A ordinary shares issuable upon such warrant exercise has been registered, qualified or deemed to be exempt under the securities laws of the state of residence of the registered holder of the warrants. In the event that the conditions in the two immediately preceding sentences are not satisfied with respect to a warrant, the holder of such warrant will not be entitled to exercise such warrant and such warrant may have no value and expire worthless. In no event will the Company be required to net cash settle any warrant. In the event that a registration statement is not effective for the exercised warrants, the purchaser of a unit containing such warrant will have paid the full purchase price for the unit solely for the Class A ordinary shares underlying such unit.

Under the terms of the warrant agreement, the Company has agreed that, as soon as practicable, but in no event later than 20 business days, after the closing of its Business Combination, it will use its commercially reasonable efforts to file with the SEC a post-effective amendment to the registration statement for the Initial Public Offering or a new registration statement covering the registration under the Securities Act of the Class A ordinary shares issuable upon exercise of the warrants and thereafter will use its commercially reasonable efforts to cause the same to become effective within 60 business days following the Company's initial Business Combination and to maintain a current prospectus relating to the Class A ordinary shares issuable upon exercise of the warrants until the expiration of the warrants in accordance with the provisions of the warrant agreement. If a registration statement covering the Class A ordinary shares issuable upon exercise of the warrants is not effective by the sixtieth (60th) business day after the closing of the initial Business Combination, warrant holders may, until such time as there is an effective registration statement and during any period when the Company will have failed to maintain an effective registration statement, exercise warrants on a "cashless basis" in accordance with Section 3(a)(9) of the Securities Act or another exemption. 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, and in the event the Company does not so elect, the Company 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.

**M3-BRIGADE ACQUISITION V CORP.**

**NOTES TO CONDENSED FINANCIAL STATEMENTS**

**SEPTEMBER 30, 2025**

**(Unaudited)**

If the holders exercise their Public Warrants on a cashless basis, they would pay the warrant exercise price by surrendering the warrants for that number of Class A ordinary shares equal to the quotient obtained by dividing (x) the product of the number of Class A ordinary shares underlying the warrants, multiplied by the excess of the "fair market value" of the Class A ordinary shares over the exercise price of the warrants by (y) the fair market value. The "fair market value" is the average reported closing price of the Class A ordinary shares for the 10 trading days ending on the third trading day prior to the date on which the notice of exercise is received by the warrant agent or on which the notice of redemption is sent to the holders of warrants, as applicable.

 ****

***Redemption of Warrants When the Price per Class A Ordinary Share Equals or Exceeds $18.00***

The Company may redeem the outstanding warrants:

● in whole and
not in part;

● at a price of
$0.01 per warrant;

● upon a minimum
of 30 days' prior written notice of redemption (the "30-day redemption period"); and

● if, and only
if, the last reported sale price (the "closing price") of the Class A ordinary shares equals or exceeds $18.00 per share
for any 20 trading days within a 30-trading day period commencing at least 150 days after completion of the initial Business
Combination and ending on the third trading day prior to the date on which the Company sends to the notice of redemption to the
warrant holders.

Additionally, if the number of outstanding Class A ordinary shares is increased by a share capitalization payable in Class A ordinary shares, or by a subdivision of ordinary shares or other similar event, then, on the effective date of such share capitalization, subdivision or similar event, the number of Class A ordinary shares issuable on exercise of each warrant will be increased in proportion to such increase in the outstanding ordinary shares. A rights offering made to all or substantially all holders of ordinary shares entitling holders to purchase Class A ordinary shares at a price less than the fair market value will be deemed a share capitalization of a number of Class A ordinary shares equal to the product of (i) the number of Class A ordinary shares actually sold in such rights offering (or issuable under any other equity securities sold in such rights offering that are convertible into or exercisable for Class A ordinary shares) and (ii) the quotient of (x) the price per class A ordinary share paid in such rights offering and (y) the fair market value. For these purposes (i) if the rights offering is for securities convertible into or exercisable for Class A ordinary shares, in determining the price payable for Class A ordinary shares, there will be taken into account any consideration received for such rights, as well as any additional amount payable upon exercise or conversion and (ii) fair market value means the volume weighted average price of Class A ordinary shares as reported during the ten (10) trading day period ending on the trading day prior to the first date on which the Class A ordinary shares trade on the applicable exchange or in the applicable market, regular way, without the right to receive such rights.

**NOTE 4. PRIVATE PLACEMENT**

Simultaneously with the closing of the Initial Public Offering, the Original Sponsor and Cantor Fitzgerald & Co., the representative of the underwriters, purchased an aggregate of 8,337,500 Private Placement Warrants, each exercisable to purchase one Class A ordinary share at $11.50 per share, at a price of $1.00 per warrant, or $8,337,500 in the aggregate. Of those 8,337,500 Private Placement Warrants, the Original Sponsor purchased 5,043,750 Private Placement Warrants and Cantor Fitzgerald & Co. purchased 3,293,750 Private Placement Warrants. Certain institutional investors who are not affiliated with any member of management (the "non-managing sponsor investors"), the Original Sponsor or any other investor in the Original Sponsor provided approximately 50.1% of the capital utilized by the Original Sponsor to purchase the Private Placement Warrants and, as a result, indirectly hold approximately 50.1% of such warrants. Each whole warrant entitles the registered holder to purchase one Class A ordinary share at a price of $11.50 per share, subject to adjustment.

The Private Placement Warrants are identical to the Public Warrants sold in the Initial Public Offering except that, so long as they are held by the Original Sponsor, Cantor Fitzgerald & Co. or their permitted transferees, the Private Placement Warrants (i) may not (including the Class A ordinary shares issuable upon exercise of these Private Placement Warrants), subject to certain limited exceptions, be transferred, assigned or sold by the holders until 30 days after the completion of the initial Business Combination, (ii) will be entitled to registration rights and (iii) with respect to Private Placement Warrants held by Cantor Fitzgerald & Co. and/or its designees, will not be exercisable more than five years from the date of the Initial Public Offering in accordance with Financial Industry Regulatory Authority Rule 5110(g)(8).

On May 23, 2025, the Company entered into the Securities Purchase Agreement with the Original Sponsor and the Sponsor, pursuant to which the Original Sponsor agreed to sell, and the Sponsor agreed to purchase, 7,187,500 Class B ordinary shares, par value $0.0001 per share, and 5,043,750 Private Placement Warrants of the Company owned by the Original Sponsor for an aggregate purchase price of $6,467,500. The transactions contemplated by the Securities Purchase Agreement were consummated on May 27, 2025. At the Closing, the Original Sponsor delivered to the Sponsor an assignment of the Transferred Sponsor SPAC Securities against payment of the Closing Cash Purchase Price. Also on May 27, 2025, the Sponsor entered into an agreement to purchase 3,293,750 additional Private Placement Warrants of the Company from Cantor Fitzgerald & Co. for an aggregate purchase price of $10, which was consummated on May 27, 2025, upon which Cantor Fitzgerald & Co. delivered to the Sponsor an assignment of the Cantor Warrants.

The Original Sponsor, officers and directors have entered into the Letter Agreement with the Company, pursuant to which they have agreed to (i) waive their redemption rights with respect to their founder shares and public shares in connection with the completion of the initial Business Combination or an earlier redemption in connection with the commencement of the procedures to consummate the initial Business Combination if the Company determines it is desirable to facilitate the completion of the initial Business Combination; (ii) waive their redemption rights with respect to their founder shares and public shares in connection with a shareholder vote to approve an amendment to the Company's amended and restated memorandum and articles of association (A) to modify the substance or timing of the Company's obligation to allow redemption in connection with the initial Business Combination or to redeem 100% of the public shares if the Company has not consummated an initial Business Combination within the Completion Window or (B) with respect to any other material provisions relating to shareholders' rights or pre-initial Business Combination activity; (iii) waive their rights to liquidating distributions from the Trust Account with respect to their founder shares if the Company fails to complete the initial Business Combination within the Completion Window, although they will be entitled to liquidating distributions from the Trust Account with respect to any public shares they hold if the Company fails to complete the initial Business Combination within the Completion Window and to liquidating distributions from assets outside the Trust Account; and (iv) vote any founder shares held by them and any public shares purchased during or after the Initial Public Offering (including in open market and privately negotiated transactions) in favor of the initial Business Combination.

Pursuant to the Securities Purchase Agreement, on May 27, 2025, the Company entered into an Assignment and Assumption Agreement with the Sponsor, the Original Sponsor and the Company's directors and executive officers, pursuant to which the Original Sponsor assigned to the Sponsor, and the Sponsor assumed, all of Original Sponsor's rights, title and interests under the Letter Agreement, and the Sponsor agreed to be bound by all terms, conditions, and covenants and be entitled to all the terms and provisions therein. The Company also entered into an Assignment and Assumption Agreement with the Sponsor and the Original Sponsor, pursuant to which the Original Sponsor assigned to the Sponsor, and the Sponsor assumed, all of Original Sponsor's rights, title and interests under the Registration Rights Agreement, dated as of July 31, 2024, by and among the Company, Original Sponsor and Cantor Fitzgerald & Co., pursuant to which the Sponsor agreed to be bound by all terms, conditions, and covenants and be entitled to all the terms and provisions therein.

**NOTE 5. RELATED PARTY TRANSACTIONS**

***Founder Shares***

 **

On March 15, 2024, the Original Sponsor made a capital contribution of $25,000, or approximately $0.004 per share, to cover certain of the Company's expenses, for which the Company issued 7,187,500 founders shares to the Original Sponsor. As the underwriters' over-allotment was exercised in full as part of the Initial Public Offering, none of the founder shares are subject to forfeiture.

The Company's initial shareholders have agreed not to transfer, assign or sell any of their founder shares and any Class A ordinary shares issued upon conversion thereof until the earlier to occur of (i) one year after the completion of the initial Business Combination or (ii) the date on which the Company completes a liquidation, merger, share exchange or other similar transaction after the initial Business Combination 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. Any permitted transferees will be subject to the same restrictions and other agreements of the Company's initial shareholders with respect to any founder shares (the "Lock-up"). Notwithstanding the foregoing, if (1) the closing price of the Class A ordinary shares equals or exceeds $12.00 per share (as adjusted for share subdivisions, share capitalizations, share consolidations, reorganizations, recapitalizations and the like) for any 20 trading days within any 30-trading day period commencing at least 150 days after the initial Business Combination or (2) if the Company consummates a transaction after the initial Business Combination which results in the Company's shareholders having the right to exchange their shares for cash, securities or other property, the founder shares will be released from the Lock-up.

On May 23, 2025, the Company entered into the Securities Purchase Agreement with the Original Sponsor and the Sponsor, pursuant to which the Original Sponsor agreed to sell, and the Sponsor agreed to purchase, 7,187,500 Class B ordinary shares, par value $0.0001 per share, and 5,043,750 Private Placement Warrants of the Company owned by the Original Sponsor for an aggregate purchase price of $6,467,500. The transactions contemplated by the Agreement were consummated on May 27, 2025. At the Closing, the Original Sponsor delivered to the Sponsor an assignment of the Transferred Sponsor SPAC Securities against payment of the Closing Cash Purchase Price.

***Convertible Promissory Note — Related Party***

The Original Sponsor had agreed to loan the Company an aggregate of up to $300,000 to be used for a portion of the expenses of the Initial Public Offering. The loan was non-interest bearing, unsecured and due on demand. As of the Initial Public Offering, the loan was repaid and was no longer available to be drawn upon.

On June 16, 2025, the Company issued a promissory note (the "Note") to the Sponsor, pursuant to which the Company can borrow up to an aggregate principal amount of $2,500,000 from the Sponsor. The Note bears no interest and is payable in full upon the consummation of the Company's initial business combination (the "Maturity Date"). A failure to pay the principal on the Maturity Date shall be deemed an event of default, in which case the Note may be accelerated. Upon consummation of a Business Combination, Sponsor shall have the option, but not the obligation, to convert up to $1,500,000 of the outstanding unpaid principal balance under this Note, into Private Placement Warrants at the purchase price of $1.00 per Private Placement Warrant, each such Private Placement Warrant exercisable to purchase one Class A ordinary share of the Company at $11.50 per share, subject to adjustment. If the Company does not consummate an initial business combination, the Note will be repaid solely to the extent the Company has funds available outside its trust account established in connection with the Company's initial public offering. On June 18, 2025 and September 19, 2025, the Company borrowed $500,000 and $1,500,000, respectively, under the Note. The proceeds of the Note will be used to provide the Company with general working capital. As of September 30, 2025 and December 31, 2024, there were $2,000,000 and $0, respectively, outstanding under the Note.

The Company accounts for the Note in accordance with ASC 470 and has determined that the embedded derivative within the Note does not require bifurcation. The Note was issued in a related-party transaction that was not conducted at arm's length. Accordingly, the Note is measured at the amount of cash proceeds received from the holder.

***Related Party Loans***

 ****

In order to finance transaction costs in connection with a Business Combination, the Sponsor or an affiliate of the Sponsor or certain of the Company's officers and directors may, but are not obligated to, loan the Company funds as may be required (the "Working Capital Loans"). If the Company completes a Business Combination, the Company would repay the Working Capital Loans. In the event that a Business Combination does not close, the Company may use a portion of the working capital held outside the Trust Account to repay the Working Capital Loans but no proceeds from the Trust Account would be used to repay the Working Capital Loans. Up to $1,500,000 of such Working Capital Loans, which would include any potential borrowings under the Note, may be convertible into private placement warrants of the post Business Combination entity at a price of $1.00 per warrant at the option of the lender. The warrants would be identical to the Private Placement Warrants.

***Advance from Related Party***

 ****

The Original Sponsor has advanced the Company $280,545 to be used for expenses related to the Initial Public Offering. Subsequently, the Original Sponsor advanced an additional $98,212 and $76,338 to the Company as of December 31, 2024 and during the nine months ended September 30, 2025, respectively. On April 4, 2025 and May 23, 2025, the Company repaid the Original Sponsor $378,757 and $51,898, respectively, of these outstanding advances.

As of September 30, 2025 and December 31, 2024, the Company had $24,440 and $378,757 in advances from related party, respectively.

 **

***Independent Directors Compensation***

 **

On June 26, 2025, the Company adopted a Non-Employee Director Compensation Plan to attract and retain highly qualified individuals to serve as non-employee directors. Effective October 1, 2025, the Company began compensating its independent directors through cash payments for their service on the Board of Directors. For the three months ended September 30, 2025, and 2024, the Company recognized $765,773 and $0, respectively, in director compensation expense within its unaudited condensed statements of operations. For the nine months ended September 30, 2025, and 2024, the Company recognized $811,500 and $0, respectively, in director compensation expense within its unaudited condensed statements of operations. The related accrued compensation, included in accrued expenses on the condensed balance sheets, was $811,500 and $0 as of September 30, 2025, and December 31, 2024, respectively.

***Registration Rights***

The holders of the founder shares, Private Placement Warrants and the Class A ordinary shares underlying such Private Placement Warrants and warrants that may be issued upon conversion of the Working Capital Loans have registration rights to require the Company to register a sale of any of the Company's securities held by them and any other securities of the Company acquired by them prior to the consummation of the initial Business Combination. The holders of these securities are entitled to make up to three demands, excluding short form demands, that the Company registers such securities. In addition, the holders have certain "piggyback" registration rights with respect to registration statements filed subsequent to the completion of the initial Business Combination. The Company will bear the expenses incurred in connection with the filing of any such registration statements.

***Equity PIPE Subscription Agreement***

Contemporaneously with the execution of the Business Combination Agreement, on July 7, 2025, certain investors (the "Equity PIPE Investors") entered into subscription agreements (collectively, the "Equity PIPE Subscription Agreements") with ReserveOne, Pubco, and solely with respect to Section 8(u) thereof, the Company, pursuant to which the Equity PIPE Investors agreed to purchase up to an aggregate of $500,000,000 of (a) either (i) ReserveOne Common Shares or (ii) in the event the issuance of ReserveOne Common Shares would, in the opinion of the Company, ReserveOne or Pubco on the advice of any of their respective legal counsel, adversely affect the treatment of the Transactions under Section 351 of the Internal Revenue Code of 1986 (the "Code"), shares Pubco Class A common stock (the "Equity PIPE Shares") and (b) either (i) ReserveOne Warrants or (ii) in the event the issuance of ReserveOne Warrants would, in the opinion of the Company, ReserveOne or Pubco and on the advice of their respective legal counsel, adversely affect the treatment of the Transactions under Section 351 of the Internal Revenue Code of 1986, Pubco Warrants ("PIPE Warrants" and, together with the Equity PIPE Shares, the "Equity PIPE Securities") at an aggregate purchase price of $10.00, which $10.00 will entitle Equity PIPE Investors to one Equity PIPE Share and one PIPE Warrant, in a private placement (the "Equity PIPE"). The PIPE Warrants (and the shares underlying the PIPE Warrants, the "Warrant Shares") will be issued pursuant to a Warrant Agreement by and among ReserveOne, Pubco and Continental Stock Transfer & Trust Company, as warrant agent (the "Warrant Agreement"). The Equity PIPE Investors are permitted, under the Equity PIPE Subscription Agreements, to satisfy their commitments thereunder if they hold Company Class A ordinary shares that qualify as Non-Redeemed Shares (as defined in the PIPE Subscription Agreement), subject to certain conditions and restrictions set forth in the Equity PIPE Subscription Agreements. The purchase price for the Equity PIPE Securities may be paid in either cash or Bitcoin, at the sole election of each of the Equity PIPE Investors.

The closing of the Equity PIPE is contingent upon the satisfaction of all closing conditions to consummate the Transactions and the Equity PIPE Investors' consent to any amendments, modifications or waivers to the terms of the Business Combination Agreement that would reasonably be expected to materially and adversely affect the economic benefits of the Equity PIPE Investors, among other customary closing conditions.

Pursuant to the Equity PIPE Subscription Agreements, the Company and Pubco have agreed to use commercially reasonable efforts to cause the Equity PIPE Securities and Warrant Shares to be registered on the Registration Statement. To the extent that any Equity PIPE Securities and Warrant Shares are unable to be included on the Registration Statement, Pubco has agreed to register and maintain the registration of the Equity PIPE Securities and Warrant Shares by filing a resale registration statement with the SEC within 30 calendar days after the Closing (at Pubco's sole cost and expense), to register the resale of the Equity PIPE Securities and Warrant Shares. Pubco has agreed to use its commercially reasonable efforts to have such resale registration statement declared effective as soon as practicable after the filing thereof, but no later than 60 calendar days after the Closing, which may be extended an additional 30 calendar days depending on whether the SEC issues comments on the resale registration statement.

Each Equity PIPE Subscription Agreement will terminate and be void and of no further force and effect, subject to certain exceptions, upon the earliest to occur of (i) such date and time as the Business Combination Agreement is terminated in accordance with its terms; (ii) the mutual written agreement of the respective parties to terminate such agreement; or (iii) July 7, 2026.

Contemporaneously with the execution of the Business Combination Agreement, on July 7, 2025, certain investors entered into subscription agreements (the "Convertible Notes Subscription Agreements" and such investors, the "Convertible Notes Investors") with Pubco, and, solely with respect to Section 9(t) thereof, the Company, pursuant to which the Convertible Notes Investors have agreed to purchase up to $250,000,000 in aggregate principal amount of Pubco's 1.00% Convertible Senior Notes (the "Initial Convertible Notes" and such subscriptions, including the purchase of any Option Convertible Notes (as defined below), the "Convertible Notes PIPE," and together with the Equity PIPE, the "PIPE Investments"), upon the terms and subject to the conditions set forth therein. In addition, for a period of 30 days following the execution of the Convertible Notes Subscription Agreements, Pubco has granted the Convertible Notes Investors an option to purchase additional convertible notes in an aggregate principal amount of up to $50 million, on a pro rata basis based on such Convertible Notes Investor's subscription for Initial Convertible Notes (the "Option Convertible Notes" and, together with the Initial Convertible Notes, the "Convertible Notes").

The net proceeds of the Convertible Notes PIPE will be converted into Bitcoin.

The closing of the Convertible Notes PIPE is contingent upon the satisfaction of all closing conditions to consummate the Transactions and the Convertible Notes Investors' consent to any amendments, modifications or waivers to the terms of the Business Combination Agreement that are material and adverse economically to the Convertible Notes Investors, among other customary closing conditions.

Pursuant to the Convertible Notes Subscription Agreements, Pubco has agreed to register and maintain the registration of the Pubco Class A Common Shares issuable upon conversion of the Convertible Notes by filing a resale registration statement with the SEC within 30 calendar days after the Closing (at Pubco's sole cost and expense), to register the resale of the Pubco Class A Common Shares. Pubco has agreed to use its commercially reasonable efforts to have such resale registration statement declared effective as soon as practicable after the filing thereof, but no later than 60 calendar days after the Closing, which may be extended an additional 30 calendar days depending on whether the SEC issues comments on the resale registration statement.

***Amended and Restated Registration Rights Agreement***

Concurrently with the consummation of the transactions contemplated by the Business Combination Agreement, the Company, Pubco, the Sponsor, the Sponsor Parent and the MI7 Holder will enter into a registration rights agreement that will amend and restate the current registration rights agreement entered into at the time of the Company's initial public offering between the Company and the Original Sponsor (the "Amended and Restated Registration Rights Agreement"), pursuant to which Pubco will (i) assume the registration obligations of the Company under such registration rights agreement and (ii) provide registration rights with respect to the resale of the Registrable Securities (as defined the Amended and Restated Registration Rights Agreement) held by the Sponsor, the Sponsor Parent and the MI7 Holder.

***Underwriters' Agreement***

The underwriters had a 45-day option from the date of the Initial Public Offering to purchase up to an additional 3,750,000 units to cover over-allotments, if any. On August 1, 2024, the underwriters 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 underwriters were entitled to a cash underwriting discount of $5,000,000 (2.0% of the gross proceeds of the Units offered in the Initial Public Offering, excluding any proceeds from Units sold pursuant to the underwriters' over-allotment option), which was paid upon the closing of the Initial Public Offering. Additionally, the underwriters are entitled to a deferred underwriting discount of 4.40% of the gross proceeds of the Initial Public Offering held in the Trust Account other than those sold pursuant to the underwriters' over-allotment option and 6.40% of the gross proceeds sold pursuant to the underwriters' over-allotment option, or $13,400,000 in the aggregate, payable upon the completion of the Company's initial Business Combination subject to the terms of the underwriting agreement.

***Risks and Uncertainties***

The United States and global markets are experiencing volatility and disruption following the geopolitical instability resulting from the ongoing Russia-Ukraine and Israel-Hamas conflicts, as well as the changes in the economic and strategic policies of the United States. Although the length and impact of these circumstances are highly unpredictable, they could lead to market disruptions, including significant volatility in commodity prices, import costs, credit and capital markets, as well as supply chain interruptions and increased cyberattacks against U.S. companies. Additionally, any new sanctions or economic policies 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 these circumstances and subsequent sanctions or other 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.

***Business Combination Agreement***

On July 7, 2025, the Company, ReserveOne, Pubco, the Merger Subs, entered into the Business Combination Agreement.

As a result of the transactions contemplated by the Business Combination Agreement, the Company will be de-registered in the Cayman Islands and register by way of continuation to the State of Delaware and domesticate as a Delaware corporation.

Following the Domestication, SPAC Merger Sub will merge with and into the Company , with the Company continuing as the surviving entity, and as a result of which the Company will be a wholly-owned subsidiary of Pubco. Promptly following the SPAC Merger, Company Merger Sub will merge with and into ReserveOne, with ReserveOne continuing as the surviving company, and as a result of which ReserveOne will be a wholly-owned subsidiary of Pubco.

As a result of the Mergers, Pubco will become a publicly traded company, all upon the terms and subject to the conditions set forth in the Business Combination Agreement and in accordance with applicable laws.

The shares of Pubco Class A common stock, par value $0.0001 per share, will be listed for trading and will be freely transferable, subject to the transfer restrictions set forth in the Sponsor Support Agreement and the Lock-Up Agreement and any restrictions pursuant to applicable laws. The shares of Pubco Class B common stock, par value $0.0001 per share, will not be listed or freely transferable.

On July 16, 2025, the Company and the Sponsor entered into the Note Amendment, solely to correct a scrivener's error regarding the Sponsor's option to convert up to $1,500,000 of the outstanding unpaid principal balance under the Note into Private Placement Warrants at a purchase price of $1.50 per Private Placement Warrant. Pursuant to the Note Amendment, the purchase price per Private Placement Warrant was corrected to reflect a purchase price of $1.00 per Private Placement Warrant upon conversion under the Note. All other terms of the Note remain unchanged.

**NOTE 7. SHAREHOLDERS' DEFICIT**

 ****

***Preferred Shares*** — The Company is authorized to issue a total of 1,000,000 preferred shares at par value of $0.0001 each. At September 30, 2025 and December 31, 2024, there were no preferred shares issued or outstanding.

 ****

***Class A Ordinary Shares*** — The Company is authorized to issue a total of 200,000,000 Class A ordinary shares at par value of $0.0001 each. At September 30, 2025 and December 31, 2024, there were no Class A ordinary shares issued or outstanding, excluding 28,750,000 Class A ordinary shares subject to possible redemption.

***Class B Ordinary Shares*** — The Company is authorized to issue a total of 20,000,000 Class B ordinary shares at par value of $0.0001 each. As of September 30, 2025 and December 31, 2024, there were 7,187,500 Class B ordinary shares issued and outstanding. The founder shares included an aggregate of up to 937,500 shares subject to forfeiture if the over-allotment option was not exercised by the underwriters in full. On August 1, 2024, the underwriters exercised their over-allotment option in full as part of the closing of the Initial Public Offering. As such, the 937,500 founder shares were no longer subject to forfeiture.

The founder shares will automatically convert into Class A ordinary shares in connection with the consummation of the initial Business Combination or earlier at the option of the holder on a one-for-one basis, subject to adjustment for share subdivisions, share capitalizations, share consolidations, reorganizations, recapitalizations and the like, and subject to further adjustment as provided herein. In the case that additional Class A ordinary shares or equity-linked securities are issued or deemed issued in connection with the initial Business Combination, the number of Class A ordinary shares issuable upon conversion of all founder shares will equal, in the aggregate, 20% of the total number of Class A ordinary shares outstanding after such conversion (after giving effect to any redemptions of Class A ordinary shares by public shareholders), including the total number of Class A ordinary shares issued, or deemed issued or issuable upon conversion or exercise of any equity-linked securities or rights issued or deemed issued, by the Company in connection with or in relation to the consummation of the initial Business Combination, excluding any Class A ordinary shares or equity-linked securities exercisable for or convertible into Class A ordinary shares issued, or to be issued, to any seller in the initial Business Combination and any Private Placement Warrants issued to the Sponsor, officers or directors upon conversion of the Working Capital Loans; provided that such conversion of founder shares will never occur on a less than one-for-one basis.

Notwithstanding the foregoing, pursuant to the terms of the Business Combination Agreement, upon the consummation of the proposed Business Combination, the founder shares will convert, on a one-for-one basis, into one share of Class A-2 common stock of ReserveOne, par value $0.0001 per share (the "<u>ReserveOne Class A-2 Common Shares</u>") and then each issued and outstanding ReserveOne Class A-2 Common Share will be automatically canceled and extinguished and converted into and thereafter represent the right to receive one share of Pubco Class B common stock, par value $0.0001 per share (the "<u>Pubco Class B Common Shares</u>"), following which, all Company Class A-2 Common Shares will cease to be outstanding and will automatically be canceled and will cease to exist. Following the consummation of the transactions contemplated by the Business Combination Agreement, each Pubco Class B Common Share will be entitled to ten votes per share on each matter submitted for a vote of Pubco's shareholders. In addition, upon consummation of the proposed Business Combination and in lieu of the anti-dilution provisions described in the prior paragraph, the Sponsor will receive an additional 5.5 million Pubco Class B Common Shares, of which 5 million shares are subject to forfeiture pursuant to the terms of the Business Combination Agreement.

Holders of record of the Company's Class A ordinary shares and Class B ordinary shares are entitled to one vote for each share held on all matters to be voted on by shareholders.

**NOTE 8. 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 based on assessment of the assumptions that market participants would use in pricing the asset or liability.

The following tables present information about the Company's assets and liabilities that are measured at fair value on a recurring basis as of September 30, 2025 and December 31, 2024 and indicate the fair value hierarchy of the valuation techniques that the Company utilized to determine such fair value. There were no transfers between levels of fair value hierarchy during the periods ended September 30, 2025 and December 31, 2024.

**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 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 reporting segment.

**M3-BRIGADE ACQUISITION V CORP.**

**NOTES TO CONDENSED FINANCIAL STATEMENTS**

**SEPTEMBER 30, 2025**

**(Unaudited)**

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 statements of operations as net income or loss. The measure of segment assets is reported on the 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:

---

The CODM reviews interest earned on investments held in 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 costs are reviewed and monitored by the CODM to manage and forecast cash to ensure enough capital is available to complete a business combination within the business combination period. The CODM also reviews general and administrative costs to manage, maintain and enforce all contractual agreements to ensure costs are aligned with all agreements and budget. General and administrative costs, as reported on the statements of operations, are the significant segment expenses provided to the CODM on a regular basis. All other segment items included in net income or loss are reported on the statements of operations and described within their respective disclosures.

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**

The Company evaluated subsequent events and transactions that occurred after the condensed balance sheet date up to the date that the unaudited condensed financial statements were issued. 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 March 12, 2024 formed for the purpose of effecting a merger, share exchange, asset acquisition, share purchase, reorganization or other similar Business Combination with one or more businesses. We intend to effectuate our Business Combination using cash derived from the proceeds of the Initial Public Offering and the sale of the Private Placement 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.

**Business Combination Agreement**

On July 7, 2025, the Company, ReserveOne, Inc., a Delaware corporation ("ReserveOne"), ReserveOne Holdings, Inc., a Delaware corporation and wholly-owned subsidiary of ReserveOne ("Pubco"), R1 SPAC Merger Sub, Inc., a Delaware corporation and a wholly-owned subsidiary of Pubco ("SPAC Merger Sub"), and R1 Company Merger Sub, Inc., a Delaware corporation and a wholly-owned subsidiary of Pubco ("Company Merger Sub" and, together with the SPAC Merger Sub, the "Merger Subs"), entered into a business combination agreement (the "Business Combination Agreement").

As a result of the transactions contemplated by the Business Combination Agreement, the Company will be de-registered in the Cayman Islands and register by way of continuation to the State of Delaware and domesticate as a Delaware corporation (the "Domestication").

Following the Domestication, SPAC Merger Sub will merge with and into the Company (the "SPAC Merger"), with the Company continuing as the surviving entity (the "SPAC Surviving Subsidiary"), and as a result of which the Company will be a wholly-owned subsidiary of Pubco. Promptly following the SPAC Merger, Company Merger Sub will merge with and into ReserveOne (the "Company Merger" and, together with the SPAC Merger, the "Mergers"), with ReserveOne continuing as the surviving company (the "Company Surviving Subsidiary"), and as a result of which ReserveOne will be a wholly-owned subsidiary of Pubco.

As a result of the Mergers, Pubco will become a publicly traded company, all upon the terms and subject to the conditions set forth in the Business Combination Agreement and in accordance with applicable laws.

The shares of Pubco Class A common stock, par value $0.0001 per share, will be listed for trading and will be freely transferable, subject to the transfer restrictions set forth in the Sponsor Support Agreement and the Lock-Up Agreement and any restrictions pursuant to applicable laws. The shares of Pubco Class B common stock, par value $0.0001 per share, will not be listed or freely transferable.

The Closing is expected to occur in the first quarter of 2026, subject to the satisfaction of certain customary closing conditions.

**Results of Operations**

We have neither engaged in any operations nor generated any revenues to date. Our only activities from March 12, 2024 (inception) through September 30, 2025, were organizational activities, those necessary to prepare for the Initial Public Offering, described below, and 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 on cash and marketable securities held in the Trust Account. We incur expenses as a result of being a public company (for legal, financial reporting, accounting and auditing compliance), as well as for due diligence expenses.

For the three months ended September 30, 2025, we had a net loss of $491,393, which consists of $2,868,287 of general and administrative costs and compensation expense of $765,773, offset by $3,142,667 from interest earned on marketable securities held in Trust Account.

For the nine months ended September 30, 2025, we had a net income of $4,606,168, which consists of $9,331,539 from interest earned on marketable securities held in Trust Account, offset by $3,913,871 of general and administrative costs and compensation expense of $811,500.

For the three months ended September 30, 2024, we had a net income of $2,010,116, which consists of $2,305,244 from interest earned on marketable securities held in Trust Account, offset by $295,128 of general and administrative costs.

For the period from March 12, 2024 (inception) through September 30, 2024, we had net income of $1,960,642, which consists of $2,305,244 from interest earned on cash held in Trust Account, offset by $344,602 of general and administrative costs.

**Liquidity and Capital Resources**

Until the consummation of the Initial Public Offering, our only source of liquidity was an initial purchase of Class B ordinary shares, par value $0.0001 per share, by the Original Sponsor and loans or advances from the Original Sponsor or another related party.

On August 2, 2024, we consummated the Initial Public Offering of 28,750,000 Units at $10.00 per Units, which includes the full exercise by the underwriters of their over-allotment option in the amount of 3,750,000 Units generating gross proceeds of $287,500,000. Simultaneously with the closing of the Initial Public Offering, we consummated the sale of an aggregate of 8,337,500 Private Placement Warrants at a price of $1.00 per Private Placement Warrant, in a private placement to the Original Sponsor and Cantor Fitzgerald & Co., the representative of the underwriters of the initial Public Offering, generating gross proceeds of $8,337,500. On May 27, 2025, the Original Sponsor and Cantor Fitzgerald & Co. sold their Private Placement Warrants to the Sponsor.

Following the Initial Public Offering, the full exercise of the over-allotment option, and the sale of the Units, a total of $288,937,500 was placed in the Trust Account. We incurred $19,406,996 of transaction costs, consisting of $5,000,000 of cash underwriting fees, $13,400,000 of deferred underwriting fees, and $1,006,996 of other offering costs.

On June 16, 2025, the Company issued the Note to the Sponsor, pursuant to which the Company can borrow up to an aggregate principal amount of $2,500,000 from the Sponsor. The Note bears no interest and is payable on the Maturity Date. A failure to pay the principal on the Maturity Date shall be deemed an event of default, in which case the Note may be accelerated. If the Company does not consummate an initial business combination, the Note will be repaid solely to the extent the Company has funds available outside its trust account established in connection with the Company's initial public offering. On July 16, 2025, the Company and the Sponsor entered into the First Amendment to the Note (the "Note Amendment"), solely to correct a scrivener's error regarding the Sponsor's option to convert up to $1,500,000 of the outstanding unpaid principal balance under the Note into Private Placement Warrants at a purchase price of $1.50 per Private Placement Warrant. Pursuant to the Note Amendment, the purchase price per Private Placement Warrant was corrected to reflect a purchase price of $1.00 per Private Placement Warrant upon conversion under the Note. All other terms of the Note remain unchanged

On June 18, 2025 and September 19, 2025 the Company borrowed $500,000 and $1,500,000, respectively, under the Note. The proceeds of the Note will be used to provide the Company with general working capital.

As of September 30, 2025, we had marketable securities held in the Trust Account of $303,948,781. We may withdraw interest from the Trust Account to pay taxes, if any. We intend to use substantially all of the funds held in the Trust Account, including any amounts representing interest earned on the Trust Account (less income taxes payable), to complete our Business Combination. To the extent that our share capital or debt is used, in whole or in part, as consideration to complete our Business Combination, the remaining proceeds held in the Trust Account will be used as working capital to finance the operations of the target business or businesses, make other acquisitions and pursue our growth strategies.

As of September 30, 2025, we had cash of $1,683,134. We intend to use the funds held outside the Trust Account primarily to identify and evaluate target businesses, perform business due diligence on prospective target businesses, travel to and from the offices, plants or similar locations of prospective target businesses or their representatives or owners, review corporate documents and material agreements of prospective target businesses, and structure, negotiate and complete a Business Combination.

In order to fund working capital deficiencies or finance transaction costs in connection with a Business Combination, the Sponsor, or certain of our officers and directors or their affiliates may, but are not obligated to, loan us funds as may be required. If we complete a Business Combination, we would repay such loaned amounts. In the event that a Business Combination does not close, we may use a portion of the working capital held outside the Trust Account to repay such loaned amounts but no proceeds from our Trust Account would be used for such repayment. Up to $1,500,000 of such Working Capital Loans, which would include any potential borrowings under the Note, may be convertible into private placement warrants of the post Business Combination entity at a price of $1.00 per warrant at the option of the lender. The warrants would be identical to the Private Placement Warrants.

The Company may need to raise additional funds, other than any potential borrowings under the Note, in order to fund the expenditures required for operating its business. However, if the estimate of the costs of completing the transactions contemplated by the agreement with respect to an initial Business Combination Agreement with ReserveOne and its affiliates are less than the actual amount necessary to do so, the Company may have insufficient funds available to operate its business prior to the completion of the transactions contemplated by the Business Combination Agreement.

Moreover, we may need to obtain additional financing either to complete our Business Combination or because we become obligated to redeem a significant number of our Public Shares upon consummation of our Business Combination, in which case we may issue additional securities or incur debt in connection with such Business Combination.

**Off-Balance Sheet Arrangements**

We have no obligations, assets or liabilities, which would be considered off-balance sheet arrangements as of September 30, 2025. We do not participate in transactions that create relationships with unconsolidated entities or financial partnerships, often referred to as variable interest entities, which would have been established for the purpose of facilitating off-balance sheet arrangements. We have not entered into any off-balance sheet financing arrangements, established any special purpose entities, guaranteed any debt or commitments of other entities, or purchased any non-financial assets.

**Contractual obligations**

We do not have any long-term debt, capital lease obligations, operating lease obligations or long-term liabilities.

The underwriters had a 45-day option from the date of the Initial Public Offering to purchase up to an additional 3,750,000 units to cover over-allotments, if any. Simultaneously with the closing of the Initial Public Offering, the underwriters elected to fully exercise the over-allotment option to purchase the additional 3,750,000 Units at a price of $10.00 per Unit.

**Critical Accounting Policies**

The preparation of unaudited condensed financial statements and related disclosures in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the unaudited condensed financial statements, and income and expenses during the periods reported. Actual results could materially differ from those estimates. We have identified no critical accounting policies.

*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 our unaudited condensed financial statements.

**Item 3. Quantitative and Qualitative Disclosures About Market Risk**

Not required for smaller reporting companies.

**Item 4. Controls and Procedures**

**Evaluation of Disclosure Controls and Procedures**

Disclosure controls are procedures that are designed with the objective of ensuring that information required to be disclosed in our reports filed under the Exchange Act is recorded, processed, summarized, and reported within the time period specified in the SEC's rules and forms. Disclosure controls are also designed with the objective of ensuring that such information is accumulated and communicated to our management, including the chief executive officer and chief financial officer, as appropriate to allow timely decisions regarding required disclosure.

As required by Rules 13a-15 and 15d-15 under the Exchange Act, our Chief Executive Officer and Chief Financial Officer carried out an evaluation of the effectiveness of the design and operation of our disclosure controls and procedures as of September 30, 2025. Based upon their evaluation, our Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) were effective. Accordingly, management believes that the unaudited condensed financial statements included in this Quarterly Report present fairly in all material respects our financial position, results of operations and cash flows for the periods presented.

**Changes in Internal Control over Financial Reporting**

There was no change in our internal control over financial reporting that occurred during the fiscal quarter of 2025 covered by this Quarterly Report 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 report include the risk factors described in our Annual Report on Form 10-K for the year ended December 31, 2024 filed with the SEC on March 28, 2025. In addition, the recent volatility and disruption resulting from recent changes and future in the economic and strategic policies of the United States could lead to market disruptions, including significant volatility in commodity prices, import costs, credit and capital markets, as well as supply chain interruptions. These disruptions 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. As of the date of this Report, there have been no material changes to the risk factors disclosed in our final prospectus for its Initial Public Offering filed with the SEC, other than those described above.

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

There were no sales of unregistered securities during the quarterly period covered by this Quarterly Report. However, simultaneously with the closing of the Initial Public Offering and pursuant to the Private Placement Units Purchase Agreement, we completed the sale of 8,337,500 Private Placement Warrants to the Original Sponsor in the Private Placement at a purchase price of $1.00 per Private Placement Warrant, generating gross proceeds to us of $8,337,500. The Private Placement Warrants (and underlying securities) are identical to the Public Warrants, except as otherwise disclosed in the IPO Registration Statement. No underwriting discounts or commissions were paid with respect to such sale. The issuance of the Private Placement Warrants was made pursuant to the exemption from registration contained in Section 4(a)(2) of the Securities Act. On May 27, 2025, the Original Sponsor and Cantor Fitzgerald & Co. sold their Private Placement Warrants to the Sponsor.

On June 16, 2025, the Company issued the Note to the Sponsor, pursuant to which the Company can borrow up to an aggregate principal amount of $2,500,000 from the Sponsor. The Note bears no interest and is payable in full on the Maturity Date. A failure to pay the principal on the Maturity Date shall be deemed an event of default, in which case the Note may be accelerated. If the Company does not consummate an initial business combination, the Note will be repaid solely to the extent the Company has funds available outside its trust account established in connection with the Company's initial public offering. On June 18, 2025, and September 19, 2025, the Company borrowed $500,000 and $1,500,000, respectively, under the Note. The issuance of the Note was made pursuant to the exemption from registration contained in Section 4(a)(2) of the Securities Act.

**Use of Proceeds**

For a description of the use of the proceeds generated in our Initial Public Offering, see Part II, Item 2 of our Quarterly Report on Form 10-Q for the quarterly period ended September 30, 2024, as filed with the SEC on November 13, 2024. There has been no material change in the planned use of proceeds from our Initial Public Offering and the Private Placement as described in the IPO Registration Statement. The specific investments in our Trust Account may change from time to time.

**Purchases of Equity Securities by the Issuer and Affiliated Purchasers**

None.

**Item 3. Defaults Upon Senior Securities**
