#### YORKVILLE ACQUISITION CORP.

#### NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

#### Note 1 — Organization and Business Operations
Yorkville Acquisition Corp. (the "Company") is a blank check company incorporated as a Cayman Islands exempted company on March 3, 2025. The Company was incorporated for the purpose of effecting a merger, share exchange, asset acquisition, share purchase, reorganization or similar business combination with one or more businesses (the "Business Combination").

As of March 31, 2026, the Company has not commenced any operations. All activity for the period from March 3, 2025 (inception) through March 31, 2026 relates to the Company's formation, the initial public offering (the "Initial Public Offering"), as defined below, and activities associated with identifying and negotiating a potential business combination. The Company will not generate any operating revenues until after the completion of its initial Business Combination, at the earliest. The Company generates non-operating income in the form of interest income on cash and cash equivalents from the proceeds derived from the Initial Public Offering. The Company has selected December 31 as its fiscal year end.

On June 30, 2025, the Company consummated the Initial Public Offering of 17,250,000 units (the "Units" and, with respect to the Class A ordinary shares included in the Units being offered, the "Public Shares"), which includes the full exercise by the underwriters of their over-allotment option in the amount of 2,250,000 Units, at $10.00 per Unit, generating gross proceeds of $172,500,000. Each Unit consists of one Class A ordinary share and one-third of one redeemable warrant (each, a "Public Warrant"). Each whole Public Warrant entitles the holder to purchase one Class A ordinary share at a price of $11.50 per share.

Simultaneously with the closing of the Initial Public Offering, the Company consummated the sale of an aggregate of 351,825 units (the "Private Placement Units" and, with respect to the Class A ordinary shares included in the Private Placement Units being offered, the "Private Placement Shares") at a price of $10.00 per Private Placement Unit, in a private placement to the Company's sponsor, Yorkville Acquisition Sponsor LLC (the "Sponsor") in the Initial Public Offering, generating gross proceeds of $3,518,250. Each Private Placement Unit consists of one Class A ordinary share (each, a "Private Placement Share") and one-third of one redeemable warrant (each, a "Private Placement Warrant"). Each whole Private Placement Warrant entitles the holder to purchase one Class A ordinary share at a price of $11.50 per share.

Transaction costs for the Initial Public Offering amounted to $9,424,463, consisting of $1,155,750 of cash underwriting fee, $5,175,000 of deferred underwriting fee (or $3,105,000 if in connection with the proposed Business Combination, as discussed further below), $2,294,250 for issuance of representative shares, and $799,463 of other offering costs.

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 income 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 June 30, 2025, an amount of $173,362,500 ($10.05 per Unit) from the net proceeds of the sale of the Units and the Private Placement Units was placed in the trust account (the "Trust Account"), with Continental Stock Transfer & Trust Company acting as trustee. The funds are to be initially invested only in 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 that invest only in direct U.S. government treasury obligations; the holding of these assets in this form is intended to be temporary and for the sole purpose of facilitating the intended Business Combination. To mitigate the risk that the Company might be deemed to be an investment company for purposes of the Investment Company Act, which risk increases the longer that the Company holds investments in the Trust Account, the Company may, at any time (based on the management team's ongoing assessment of all factors related to the Company's potential status under the Investment Company Act), instruct the trustee to liquidate the investments held in the Trust Account and instead to hold the funds in the trust account in cash or in an interest-bearing demand deposit account 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

[**Table of Contents**](#TOC)

any, the proceeds from the Initial Public Offering and the sale of the Private Placement Units 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 Company's 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 (other than excise or similar taxes)), divided by the number of then outstanding Public Shares, subject to the limitations. The amount in the Trust Account is initially anticipated to be $10.05 per Public Share. The Public Shares subject to redemption were recorded at redemption value and classified as temporary equity upon the completion of the Initial Public Offering, in accordance with Financial Accounting Standards Board ("FASB") Accounting Standards Codification ("ASC") Topic 480, "Distinguishing Liabilities from Equity."

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 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 (other than excise or similar taxes) 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 Sponsor, officers and directors have entered into a letter agreement with the Company, pursuant to which they have agreed to (i) waive their redemption rights with respect to their Founder Shares (as defined in Note 6) and Public Shares in connection with 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; (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, aside from shares they may purchase in compliance with the requirements of Rule 14e-5 under the Exchange Act, which would not be voted in favor of approving the Business Combination) in favor of the initial Business Combination.

The Company's 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, 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, 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 (other than excise or similar taxes), 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,

[**Table of Contents**](#TOC)

including liabilities under the Securities Act of 1933, as amended (the "Securities Act"). However, the Company has not asked the Sponsor to reserve for such indemnification obligations, nor has the Company independently verified whether the Sponsor has sufficient funds to satisfy its indemnity obligations, and the Company believes that the Sponsor's only assets are securities of the Company. Therefore, the Company cannot assure that the Sponsor would be able to satisfy those obligations.

#### Business Combination Agreement
On August 25, 2025, the Company executed a Business Combination Agreement (the "Business Combination Agreement"), with YA S3 Inc., a Florida corporation and an indirect wholly owned subsidiary of the Company ("SPAC Sub"), Foris Holdings KY Limited, a Cayman Islands exempted company known commercially as Crypto.com ("Crypto.com"), Crypto.com Strategy Holdings, a Cayman Islands exempted company ("Crypto.com Sub"), Yorkville Acquisition Sponsor, LLC, a Delaware limited liability company ("Sponsor"), and Trump Media & Technology Group Corp., a Florida corporation ("TMTG" and together with Crypto.com Sub and the Sponsor, the "Sellers").

Pursuant to the terms of the Business Combination Agreement, the Sellers will contribute certain assets to the Company and SPAC Sub (as applicable) in exchange for Transaction Shares (as defined in the Business Combination Agreement), the Forced Exercise Warrants (as defined below) and the Earnout Warrants (as defined below) (as applicable).

Pursuant to and concurrently with the execution of the Business Combination Agreement (the "Business Combination Closing"), Crypto.com entered into an Asset Contribution Agreement with Crypto.com Sub (the "Pre-Closing Crypto.com Contribution Agreement 1") pursuant to which, immediately prior to, but contingent upon, the Business Combination Closing, Crypto.com will contribute (the "Pre-Closing Crypto.com Contribution") 6,313,000,212 Cronos tokens and all necessary physical devices required to establish and operate a Cronos proof of stake validator node and staking infrastructure (the "Cronos Assets") to Crypto.com Sub.

Pursuant to and concurrently with the execution of the Business Combination Agreement, Crypto.com Sub entered into an Asset Contribution Agreement with the Company (the "Crypto.com Contribution and Sale Agreement" and, together with the Crypto.com Pre-Closing Contribution Agreement 1, the "Crypto.com Contribution Agreements") pursuant to which, at the Business Combination Closing, (a) Crypto.com Sub will (1) at the Business Combination Closing, sell 90% of the Cronos Assets to SPAC Sub and (2) immediately following the Business Combination Closing, contribute 10% of the Cronos Assets to the Company in consideration of an aggregate 100,000,000 shares of SPAC Class B common Stock ("SPAC Class B Common Stock"), and a Forced Exercise Warrant, exercisable for 10,000,000 shares of SPAC Class A common stock ("SPAC Class A Common Stock"). In connection with the consummation of the Crypto.com Contribution and Sale Agreement, at the Business Combination Closing, Crypto.com will license to the Company, pursuant to a Trademark License Agreement, certain intellectual property and all operational knowhow and proprietary technology required to establish and operate a Cronos proof of stake validator node, and staking infrastructure.

Pursuant to and concurrently with the execution and delivery of the Business Combination Agreement, TMTG entered into a trademark license agreement (the "TMTG License Agreement"), with Trump Media Group, LLC, a Florida limited liability company, ("Asset Company") pursuant to which, immediately prior to, but contingent upon, the Business Combination Closing, TMTG will license the rights to use the "Trump Media Group" brand name and certain other intellectual property rights to the Asset Company (the "Pre-Closing TMTG Contribution" and together with the Pre-Closing Crypto.com Contribution, the "Pre-Closing Contributions").

Pursuant to and concurrently with the execution and delivery of the Business Combination Agreement, TMTG entered into an asset contribution agreement with the Company (the "TMTG Contribution Agreement") and, together with the Crypto.com Contribution Agreements and the TMTG License Agreement, the "Contribution Agreements") pursuant to which, at the Business Combination Closing, TMTG will contribute 100% of the issued and outstanding membership interests of the Asset Company (the "Asset Company Interests") to the Company in consideration of 10,000,000 shares of SPAC Class A Common Stock, the Earnout Warrants (as described below) and a Forced Exercise Warrant, exercisable for 10,000,000 shares of SPAC Class A Common Stock (the "Forced Exercise Warrant").

[**Table of Contents**](#TOC)

At the Business Combination Closing, subject to the terms and conditions set forth in the Business Combination Agreement and pursuant to the Contribution Agreements, the Sellers will sell to the Company (or SPAC Sub, as applicable), and the Company (or SPAC Sub, as applicable) will purchase from the Sellers, the Cronos Assets and the Asset Company Interests (as applicable) as follows:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) Crypto.com Sub will (i) sell to SPAC Sub, and SPAC Sub will purchase from Crypto.com Sub, all right, title and interest in and to 90% of the Cronos Assets, free and clear of all liens, in consideration of 90,000,000 shares of SPAC Class B Common Stock, and (ii) contribute to the Company, and the Company shall receive from Crypto.com Sub, all right, title and interest in and to 10% of the Cronos Assets, free and clear of all liens, in consideration of 10,000,000 shares of SPAC Class B Common Stock and a Forced Exercise Warrant, exercisable for 10,000,000 shares of SPAC Class A Common Stock. The consideration will be allocated to SPAC Sub and the Company pursuant to the Crypto.com Contribution and Sale Agreement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) TMTG will sell to the Company, and the Company will purchase from TMTG, all right, title and interest in and to the Asset Company Interests, free and clear of all liens, in consideration of 10,000,000 shares of SPAC Class A Common Stock and a Forced Exercise Warrant, exercisable for 10,000,000 shares of SPAC Class A Common Stock.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) Additionally, in exchange for such Asset Company Interests, the Company will issue three Earnout Warrants to TMTG, each exercisable for a number of shares of SPAC Class A Common Stock equal to 7% of the Company's outstanding capital stock at the time of the Business Combination Closing, rounded to the nearest whole number. Each Earnout Warrant will be exercisable within 30 days of the occurrence of the applicable triggering event as described in the Earnout Warrants (each, an "Earnout Warrant").

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d) The Company will issue to the Sponsor a Forced Exercise Warrant exercisable (on or after the Business Combination Closing) for 2,000,000 shares of SPAC Class A Common Stock.

See Form 8-K filed with the SEC on August 26, 2025 for further discussion on the Business Combination.

#### Liquidity and Capital Resources
As of March 31, 2026, the Company had $60,261 of cash and a working capital deficit of $2,258,970. The Company's liquidity needs prior to the consummation of the Initial Public Offering were satisfied through receipt of $25,000 from the Sponsor in exchange for the issuance of Founder Shares, and up to $300,000 under the Promissory Note (as defined in Note 6). On July 2, 2025, the Promissory Note was repaid in full. In connection with the Company's assessment of going concern considerations in accordance with FASB ASC Topic 205-40, "Presentation of Financial Statements — Going Concern", subsequent to the consummation of the Initial Public Offering, the Company's liquidity has been satisfied through the net proceeds from the consummation of the Initial Public Offering and the Private Placement held outside of the Trust Account.

The Company has incurred and expects to continue to incur significant costs in pursuit of its financing and acquisition plans. The Company lacks the financial resources it needs to sustain operations for a reasonable period of time, which is considered to be one year from the issuance date of the financial statements. Based on the foregoing, these factors, among others, raise substantial doubt about the Company's ability to continue as a going concern one year from the date the financial statements are issued. The financial statements do not include any adjustments that might result from the outcome of this uncertainty. Management plans to address this uncertainty through a Business Combination. The Company cannot be assured that its plans to consummate an Initial Business Combination will be successful.

#### Note 2 — Significant Accounting Policies

#### Basis of Presentation
The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America ("GAAP") for interim financial information and in accordance with the instructions to Form 10-Q and Article 8 of Regulation S-X of the U.S. Securities and Exchange Commission ("SEC"). Certain information or footnote disclosures normally included in financial statements prepared in accordance with GAAP have been condensed or omitted, pursuant to the rules and regulations of the SEC for interim financial reporting. Accordingly, the accompanying unaudited condensed financial statements do not include all the information and footnotes necessary for a complete presentation of financial position, results of operations, or cash flows.

[**Table of Contents**](#TOC)

In the opinion of management, the accompanying unaudited condensed consolidated 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 period presented.

The accompanying unaudited condensed financial statements should be read in conjunction with the Company's Annual Report on Form 10-K for the year ended December 31, 2025, which contains the audited financial statements and notes thereto. The financial information as of December 31, 2025 is derived from the audited financial statements presented in the Company's Annual Report on Form 10-K for the year ended December 31, 2025. The interim results for the three months ended March 31, 2026 are not necessarily indicative of the results to be expected for the year ending December 31, 2026 or for any future periods.

#### Emerging Growth Company Status
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, reduced disclosure obligations regarding executive compensation in its periodic reports and proxy statements, and exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and shareholder approval of any golden parachute payments not previously approved.

Further, Section 102(b)(1) of the JOBS Act exempts emerging growth companies from being required to comply with new or revised financial accounting standards until private companies (that is, those that have not had a Securities Act registration statement declared effective or do not have a class of securities registered under the Exchange Act) are required to comply with the new or revised financial accounting standards. The JOBS Act provides that 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 condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements and the reported amounts of expenses during the reporting period.

Making estimates requires management to exercise significant judgement. It is at least reasonably possible that the estimate of the effect of a condition, situation or set of circumstances that existed at the date of the condensed consolidated financial statements, which management considered in formulating its estimate, could change in the near term due to one or more future confirming events. One of the more significant accounting estimates included in these financial statements is the determination of the fair value of the warrant liabilities. Such estimates may be subject to change as more current information becomes available and accordingly, the actual results could differ significantly from those estimates.

#### Principles of Consolidation
The condensed consolidated financial statements include the accounts of the Company and its wholly-owned subsidiary, YA S3 Inc., which is inactive. All intercompany balances and transactions are eliminated in consolidation.

#### 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 $60,261 and $212,099 of cash and no cash equivalents, respectively as of March 31, 2026 and December 31, 2025.

[**Table of Contents**](#TOC)

#### Investments Held in Trust Account
At March 31, 2026 and December 31, 2025, the assets in the Trust Account, amounting to $177,932,677 and $176,338,275, respectively, were held in money market funds backed by treasury securities in accordance with the Trust Agreement.

#### Offering Costs Associated with the Initial Public Offering
The Company complies with the requirements of the ASC 340-10-S99 and SEC Staff Accounting Bulletin Topic 5A, "Expenses of Offering." Deferred offering costs consist principally of professional and registration fees that are related to the Initial Public Offering. FASB ASC 470-20, "Debt with Conversion and Other Options," addresses the allocation of proceeds from the issuance of convertible debt into its equity and debt components. The Company applies this guidance to allocate Initial Public Offering proceeds from the Units between Class A ordinary shares and Public Warrants, using the residual method by allocating Initial Public Offering proceeds first to assigned value of the Public Warrants and then to the Class A ordinary shares. Offering costs allocated to the Public Shares were charged to temporary equity, and offering costs allocated to the Public Warrants and Private Placement Units were charged to shareholders' deficit as the Public and Private Placement Warrants, after management's evaluation, were accounted for under equity treatment.

Transaction costs for the Initial Public Offering amounted to $9,424,463, consisting of $1,155,750 of cash underwriting fee, $5,175,000 of deferred underwriting fee (or $3,105,000 if in connection with the proposed Business Combination, as discussed further below), $2,294,250 for issuance of representative shares, and $799,463 of other offering costs.

#### 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 balance sheet, primarily due to their short-term nature.

Fair value is defined as the price that would be received for sale of an asset or paid to transfer of a liability in an orderly transaction between market participants at the measurement date. U.S. GAAP establishes a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). These tiers include:

● Level 1, defined as observable inputs such as quoted prices (unadjusted) for identical instruments in active markets;

● Level 2, defined as inputs other than quoted prices in active markets that are either directly or indirectly observable such as quoted prices for similar instruments in active markets or quoted prices for identical or similar instruments in markets that are not active; and

● Level 3, defined as unobservable inputs in which little or no market data exists, therefore requiring an entity to develop its own assumptions, such as valuations derived from valuation techniques in which one or more significant inputs or significant value drivers are unobservable.

#### Income Taxes
The Company accounts for income taxes under ASC Topic 740, "Income Taxes," which requires an asset and liability approach to financial accounting and reporting for income taxes. Deferred income tax assets and liabilities are computed for differences between the financial statement and tax bases of assets and liabilities that will result in future taxable or deductible amounts, based on enacted tax laws and rates applicable to the periods in which the differences are expected to affect taxable income. Valuation allowances are established, when necessary, to reduce deferred tax assets to the amount expected to be realized.

ASC Topic 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 March 31, 2026 and December 31, 2025, there were no unrecognized tax benefits and no amounts accrued for interest and penalties. The Company is currently not aware of any issues under review that could result in significant payments, accruals or material deviation from its position.

[**Table of Contents**](#TOC)

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

#### Derivative Financial Instruments
The Company evaluates its financial instruments to determine if such instruments are derivatives or contain features that qualify as embedded derivatives in accordance with ASC Topic 815, "Derivatives and Hedging". For derivative financial instruments that are accounted for as liabilities, the derivative instrument is initially recorded at its fair value on the grant date and is then re-valued at each reporting date, with changes in the fair value reported in the statements of operations. The classification of derivative instruments, including whether such instruments should be recorded as liabilities or as equity, is evaluated at the end of each reporting period. Derivative liabilities are classified in the balance sheet as current or non-current based on whether or not net cash settlement or conversion of the instrument could be required within 12 months of the condensed consolidated balance sheet date. As of March 31, 2026 and December 31, 2025, there were no derivative liabilities.

**Net Income Per Ordinary Share** 

The Company has two classes of shares, Class A ordinary shares and Class B ordinary shares. Income and losses are shared pro rata between the two classes of shares. The Company complies with the accounting and disclosure requirements of ASC Topic 260, "Earnings Per Share". Net income per share is computed by dividing net income (loss) by the weighted average number of ordinary shares outstanding for the period. Accretion associated with redeemable Class A ordinary shares is excluded from earnings per share as the redemption value approximates fair value.

The Company has not considered the effect of the Public Warrants in the calculation of diluted net income per share, since the exercise of such warrants is contingent upon the occurrence of future events and the inclusion of such warrants would be anti-dilutive.

The following table presents a reconciliation of the numerator and denominator used to compute basic and diluted net income (loss) per ordinary share for each class of ordinary shares for the three months ended March 31, 2026:

---

| | | | |
|:---|:---|:---|:---|
|  | **For the Three Months Ended** | **For the Three Months Ended** | **For the Three Months Ended** |

|  | **Class A**<br>**Redeemable** | **Class A** <br>**Non-redeemable** | **Class B** <br>**Non-redeemable** |
| Basic and diluted net income per ordinary shares: |  |  |  |
| *Numerator:* |  |  |  |
| &nbsp;&nbsp;Allocation of net income, basic and diluted | $690076 | $23253 | $230026 |

| &nbsp;&nbsp;Basic and diluted net income per ordinary share | $0.04 | $0.04 | $0.04 |

---

The earnings per share presented in the statement of operations for the period from March 3, 2025 (inception) through March 31, 2025 is based on the following:

---

| Basic and diluted weighted average Class B Ordinary Shares outstanding | 5000000 |
| Basic and diluted net loss per share | $(0.01) |

---

[**Table of Contents**](#TOC)

#### Warrant Instruments
The Company accounted for the Public Warrants and Private Placement Warrants issued in connection with the Initial Public Offering and the private placement in accordance with the guidance contained in FASB ASC Topic 815, "Derivatives and Hedging". Accordingly, the Company evaluated and classified the warrant instruments under equity treatment at their assigned values. Such guidance provides that the Public Warrants described above will not be precluded from equity classification. Equity-classified contracts are initially measured at fair value (or allocated value). Subsequent changes in fair value are not recognized as long as the contracts continue to be classified in equity in accordance with ASC 480 and ASC 815.

#### Class A Ordinary Shares Subject to Possible Redemption
The Public Shares contain a redemption feature which allows for the redemption of such Public Shares in connection with the Company's liquidation, or if there is a shareholder vote or tender offer in connection with the Company's initial Business Combination. In accordance with ASC 480-10-S99, the Company classifies Public Shares subject to possible redemption outside of permanent deficit as the redemption provisions are not solely within the control of the Company. The Company recognizes changes in redemption value immediately as they occur and will adjust the carrying value of redeemable shares to equal the redemption value at the end of each reporting period. Immediately upon the closing of the Initial Public Offering, the Company recognized the accretion from initial book value to redemption 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, as of March 31, 2026, 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 consolidated balance sheet. As of March 31, 2026, the Class A ordinary shares subject to possible redemption reflected in the condensed consolidated balance sheet are reconciled in the following table:

---

| | |
|:---|:---|
| Gross proceeds from Initial Public Offering | $172500000 |
| Less: |  |

| **Class A ordinary shares subject to possible redemption at March 31, 2026** | $**177932677** |

**Accounting Standards Not Yet Adopted** 

In November 2024, the FASB issued Accounting Standards Update ("ASU") 2024-03, "Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures" ("ASU 2024-03"), which requires entities to disclose details about specific expenses, such as inventory purchases, employee compensation, depreciation, amortization and depletion, included within commonly presented income statement expense captions. The disaggregated expense captions must be disclosed in a tabular format in the notes to the financial statements. ASU 2024-03 is effective for annual periods beginning on January 1, 2027 and interim periods beginning on January 1, 2028. The Company is currently evaluating the impact of adopting ASU 2024-03 on its financial statements and related disclosures.

In December 2025, the FASB issued Accounting Standards Update ("ASU") 2025-11, "Interim Reporting (Topic 270): Narrow-Scope Improvements" ("ASU 2025-11"), which clarifies the guidance in Topic 270 to improve the consistency of interim financial reporting. The ASU provides a comprehensive list of required interim disclosures and introduces a disclosure principle requiring entities to disclose events since the end of the last annual reporting period that have a material impact on the entity. ASU 2025-11 is effective for fiscal years beginning after December 15, 2027, including interim periods within those fiscal years, with early adoption permitted. The Company is currently evaluating the impact of adopting ASU 2025-11 on its consolidated financial statements and related disclosures.

[**Table of Contents**](#TOC)

#### Note 3 — Initial Public Offering
Pursuant to the Initial Public Offering on June 30, 2025, the Company sold 17,250,000 Units at a purchase price of $10.00 per Unit, which includes the full exercise of the underwriters' over-allotment option in the amount of 2,250,000 Units. Each Unit consists of one Class A ordinary share and one-third of one redeemable warrant. Each whole Public Warrant entitles the holder to purchase one Class A ordinary share at a price of $11.50 per share, subject to adjustment. Each Public Warrant will not become exercisable until 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.

#### Note 4 — Private Placement
Simultaneously with the closing of the Initial Public Offering, the Sponsor purchased an aggregate of 351,825 Private Placement Units, at a price of $10.00 per unit, or $3,518,250 in the aggregate. Each Private Placement Unit consists of one Private Placement Share and one-third of one Private Placement Warrant. Each whole Private Placement Warrant entitles the holder to purchase one Class A ordinary share at a price of $11.50 per share.

The Private Placement Warrants will be identical to the Public Warrants sold in the Initial Public Offering except that, so long as they are held by the Sponsor, or their permitted transferees, the Private Placement Warrants (i) will not be redeemable, (ii) 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, (iii) may be exercised by the holders on a cashless basis, and (iv) will be entitled to registration rights.

The Sponsor, officers and directors entered into a letter agreement with the Company, pursuant to which they agreed to (i) waive their redemption rights with respect to any shares held by them in connection with the completion of the initial Business Combination; (ii) waive their redemption rights with respect to any shares held by them in connection with a shareholder vote to approve an amendment to the 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 and Private Placement Shares if the Company fails to complete an 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 an initial Business Combination within the prescribed time frame and to liquidating distributions from assets outside the Trust Account; and (iv) vote any Founder Shares and Private Placement Shares held by them and any Public Shares purchased during or after this offering (including in open market and privately-negotiated transactions, aside from shares they may purchase in compliance with the requirements of Rule 14e-5 under the Exchange Act, which would not be voted in favor of approving the Business Combination transaction) in favor of the initial Business Combination.

#### Note 5 — Segment Information
ASC Topic 280, "Segment Reporting", establishes standards for companies to report, in their financial statements, information about operating segments, products, services, geographic areas, and major customers. Operating segments are defined as components of an enterprise that engage in business activities from which it may recognize revenues and incur expenses, and for which separate financial information is available that is regularly evaluated by the Company's chief operating decision maker, or group, in deciding how to allocate resources and assess performance.

The Company's chief operating decision maker ("CODM") has been identified as the Chief Financial Officer, who reviews the assets, operating results, and financial metrics for the Company as a whole to make decisions about allocating resources and assessing financial performance. Accordingly, management has determined that the Company only has one reporting segment.

[**Table of Contents**](#TOC)

The CODM assesses performance for the single segment and decides how to allocate resources based on net income or loss that also is reported on the statement of operations as net income or loss. The measure of segment assets is reported on the condensed consolidated balance sheet as total assets. When evaluating the Company's performance and making key decisions regarding resource allocation, the CODM reviews several key metrics included in net income or loss and total assets, which include the following:

---

| | |
|:---|:---|
|  | **March 31,** <br>**2026** |
| Cash | $60261 |
| Investments held in Trust Account | $177932677 |

---

---

| | |
|:---|:---|
|  | **For the Three** <br> **Months Ended**<br>**March 31, 2026** |
| General and administrative expenses | $652277 |
| Income earned on cash and marketable securities held in Trust Account | $1594402 |

---

The CODM reviews cash 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 expenses are reviewed and monitored by the CODM to manage and forecast cash to ensure enough capital is available to complete a Business Combination or similar transaction within the Completion Window. The CODM also reviews general and administrative expenses to manage, maintain and enforce all contractual agreements to ensure costs are aligned with all agreements and budget.

#### Note 6 — Related Party Transactions

#### Founder Shares
On March 5, 2025, the Company issued an aggregate of 5,750,000 Class B ordinary shares, $0.0001 par value (the "Founder Shares"), in exchange for a $25,000 payment (approximately $0.004 per share) from the Sponsor to cover certain expenses on behalf of the Company.

As used herein, unless the context otherwise requires, "Founder Shares" shall be deemed to include the Public Shares issuable upon conversion thereof. The Founder Shares are identical to the Public Shares included in the Units being sold in the Initial Public Offering except that the Founder Shares automatically convert into Public Shares at the time of the initial Business Combination (with such conversion taking place immediately prior to, simultaneously with, or immediately following the time of the initial Business Combination, as may be determined by the directors of the Company) or earlier at the option of the holder and are subject to certain transfer restrictions, as described in more detail below. The Sponsor has agreed to forfeit up to an aggregate of 750,000 Founder Shares to the extent that the over-allotment option is not exercised in full by the underwriters so that the Founder Shares will represent approximately 25% of the Company's issued and outstanding shares after the Initial Public Offering. If the Company increases or decreases the size of the offering, the Company will effect a share capitalization or share surrender, as applicable, immediately prior to the consummation of the Initial Public Offering in such amount as to maintain the Founder Share ownership of the Company's shareholders prior to the Initial Public Offering at 25% of the Company's issued and outstanding ordinary shares upon the consummation of the Initial Public Offering. The Sponsor will not be entitled to redemption rights with respect to any Founder Shares and any Public Shares held by the Sponsor in connection with the completion of the initial Business Combination. If the initial Business Combination is not completed within 24 months from the closing of the Initial Public Offering, the Sponsor will not be entitled to rights to liquidating distributions from the Trust Account with respect to any Founder Shares held by it.

The Sponsor has agreed not to transfer, assign or sell any of its Founder Shares until the earlier to occur of (A) one year after the completion of the initial Business Combination or (B) subsequent to the initial Business Combination (x) if the last reported sale price of the Class A ordinary shares equals or exceeds $12.00 per share (as adjusted for share sub-divisions, share capitalizations, rights

[**Table of Contents**](#TOC)

issuances, 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 (y) the date on which the Company completes a liquidation, merger, share exchange, reorganization or other similar transaction that results in all of the public shareholders having the right to exchange their ordinary shares for cash, securities or other property.

#### Promissory Note — Related Party
The Sponsor 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 "Promissory Note"). The Promissory Note was non-interest bearing, unsecured and due at the earlier of March 25, 2026, or the closing of the Initial Public Offering. As of June 30, 2025, the Company had borrowed $124,723 under the Promissory Note. On July 2, 2025, the Company repaid the Promissory Note in full to the Sponsor. The Promissory Note was non-interest bearing and no amounts are outstanding as of December 31, 2025. Borrowings under the Promissory Note are no longer available.

**Due to Related Party** 

On December 30, 2025, the Board of Directors (the "Board") of Yorkville Acquisition Corp., approved the payment by the Company of a monthly advisory fee of $15,000 payable to the Company's Chief Executive Officer, Kevin McGurn, in connection with identifying, investigating, negotiating and completing the Company's initial Business Combination and related matters. The advisory fee is effective as of October 2025 and will continue on a monthly basis until the earlier of (i) the closing and completion of the Company's initial business combination and (ii) the liquidation of the Company.

As of March 31, 2026 and December 31, 2025, there is $15,000 and $45,000, respectively, in due to related party related to the agreement. The Company incurred $45,000 and $0, respectively, for the three months ended March 31, 2026 and for the period from March 3, 2025 (inception) through March 31, 2025. Amounts have been included in general and administrative expenses in the accompanying statement of operations.

#### Related Party Loans
In addition, in order to finance transaction costs in connection with its initial Business Combination, the Sponsor or an affiliate of the Sponsor, or the Company's officers and directors may, but are not obligated to, loan the Company funds as may be required ("Working Capital Notes"). If the Company completes its initial Business Combination, the Company would repay the Working Capital Notes. In the event that the initial Business Combination does not close, the Company may use a portion of proceeds held outside the Trust Account to repay the Working Capital Notes but no proceeds held in the Trust Account would be used to repay the Working Capital Notes. If the Sponsor makes any Working Capital Notes, of which up to $1,500,000 of such Working Capital Notes may be convertible into private placement-equivalent units of the post-Business Combination entity at a price of $10.00 per unit ("Working Capital Units"), with each unit comprised of one Class A ordinary share ("Working Capital Share") and one-third of one warrant to purchase one Class A ordinary share at an exercise price of $11.50 per share ("Working Capital Warrant"). On February 11, 2026, the Company issued a convertible unsecured promissory note (the "Working Capital Note") in the aggregate principal amount of $250,000 to the Sponsor in order to provide the Company with additional working capital. Pursuant to the terms of the Working Capital Note, the principal balance shall not accrue interest; shall be payable by the Company on the earlier of the date on which Company consummates its initial Business Combination or the date that the winding up of the Company is effective; and is convertible at the Sponsor's election upon the consummation of the Company's initial business combination. Should the Sponsor elect to convert all or a portion of the principal balance, the elected principal balance amount will convert, at a price of $10.00 per unit, into units identical to the Private Placement Units issued in connection with the Company's Initial Public Offering (each, a "Working Capital Unit"), rounded down to the nearest whole number. On February 19, 2026, the Company drew $250,000 against the Working Capital Note. As of March 31, 2026, there is $250,000 outstanding under the Working Capital Note. The Company has relied upon Section 4(a)(2) of the Securities Act of 1933, as amended, in connection with the issuance of the Working Capital Note.

Additionally, in order to finance potential extensions, the Sponsor or an affiliate of the Sponsor, or the Company's officers and directors may, but are not obligated to, loan the Company up to $3,450,000 in extension loans (assuming the underwriters exercise their over-allotment option and no Public Shares have been redeemed at the time of each extension), as may be required ("Extension Loans"). The Extension Loans may be convertible private placement-equivalent units of the post-business combination entity at a price of $10.00 per unit ("Extension Units"), with each unit comprised of one Class A ordinary share ("Extension Share") and one-third of one warrant to purchase one Class A ordinary share at an exercise price of $11.50 per share ("Extension Warrant"). As of March 31, 2026 and December 31, 2025, the Company had no borrowings under the Extension Loans.

#### Note 7 — Commitments and Contingencies

#### Risks and Uncertainties
United States and global markets are experiencing volatility and disruption following the geopolitical instability resulting from the ongoing wars between Russia and Ukraine and between Israel and Hamas, Iran and its proxies in certain of the neighboring countries in the Middle East. In response to the ongoing war between Russia and Ukraine, the North Atlantic Treaty Organization ("NATO") deployed additional military forces to eastern Europe, and the United States, the United Kingdom, the European Union and other countries have announced various sanctions and restrictive actions against Russia, Belarus and related individuals and entities, including the removal of certain financial institutions from the Society for Worldwide Interbank Financial Telecommunication ("SWIFT") payment system. Certain countries, including the United States, have also provided and may continue to provide military aid or other assistance to Ukraine and to Israel, increasing geopolitical tensions among a number of nations. The ongoing wars between Russia and Ukraine and between Israel and Hamas, Iran and its proxies in certain of the neighboring countries in the Middle East and the resulting measures that have been taken, and could be taken in the future, by NATO, the United States, the United Kingdom, the European Union, Israel and its neighboring states and other countries have created global security concerns that could have a lasting impact on regional and global economies. Although the length and impact of the ongoing conflicts are highly unpredictable, they could lead to market disruptions, including significant volatility in commodity prices, credit and capital markets, as well as supply chain interruptions and increased cyber-attacks against U.S. companies. Additionally, any resulting sanctions could adversely affect the global economy and financial markets and lead to instability and lack of liquidity in capital markets.

Any of the above mentioned factors, or any other negative impact on the global economy, capital markets or other geopolitical conditions resulting from the ongoing wars between Russia and Ukraine, Israel and Hamas, Iran and its proxies in certain of the neighboring countries in the Middle East and subsequent sanctions or related actions, could adversely affect the Company's search for an initial Business Combination and any target business with which the Company may ultimately consummate an initial Business Combination.

#### Registration Rights
The holders of the Founder Shares, placement units, Working Capital Units and Extension Units that may be issued upon conversion of loans made by the Sponsor or one of its affiliates, and their permitted transferees, will have registration rights to require the Company to register a sale of any of its securities held by them (in the case of the Founder Shares, only after conversion to our Class A ordinary shares) pursuant to a registration rights agreement to be signed prior to or on the effective date of this offering. These holders will be entitled to make up to three demands, excluding short form registration demands, that we register such securities for sale under the Securities Act. In addition, these holders will have "piggy-back" registration rights to include such securities in other registration statements filed by us and rights to require us to register for resale such securities pursuant to Rule 415 under the Securities Act. However, the registration rights agreement provides that we will not be required to effect or permit any registration or cause any registration statement to become effective until termination of the applicable lock-up period. We will bear the expenses incurred in connection with the filing of any such registration statements.

#### Underwriting Agreement
The Company granted the underwriters a 45-day option from the date of the Initial Public Offering to purchase up to an additional 2,250,000 units to cover over-allotments, if any. On June 30, 2025, the underwriters fully exercised their over-allotment option.

The underwriters were paid a cash underwriting discount of $1,155,750 ($0.067 per Unit offered in the Initial Public Offering). Additionally, the underwriters are entitled to a deferred fee of $0.30 per Unit, or $5,175,000. The deferred fee will become payable to the underwriters from the amounts held in the Trust Account solely in the event that the Company completes a Business Combination, subject to the terms of the underwriting agreement. On August 25, 2025, the underwriters agreed to reduce the deferred underwriting discount to $0.18 per Unit sold in the Initial Public Offering, or $3,105,000, in connection with the proposed Business Combination contemplated by the Business Combination Agreement. If the Company consummates a Business Combination other than the proposed Business Combination, the deferred underwriting discount will remain $0.30 per Unit, or $5,175,000.

[**Table of Contents**](#TOC)

#### Representative Shares
The Company issued to Clear Street and/or its designees 229,425 Class A ordinary shares (the "Representative Shares") upon the consummation of the Initial Public Offering. The Company estimated the fair value of the Representative Shares to be $2,294,250. The fair value of the Representative Shares was determined to be $10.00 per share as the Representative Shares were issued at approximately the same time as the units sold at $10.00 per unit in the Initial Public Offering. The Company accounted for the Representative Shares as an expense of the Initial Public Offering, resulting in a charge directly to shareholder's equity and will not require remeasurement after issuance. Clear Street (and any of its designees to whom the Representative Shares are issued) agree not to transfer, assign or sell any such shares without the Company's prior consent until the completion of a Business Combination. In addition, the Representative Shares are deemed to be underwriting compensation by the Financial Industry Regulatory Authority, Inc. ("FINRA") pursuant to FINRA Rule 5110 and will, accordingly, be subject to certain transfer restrictions or a period of 180 days beginning on the date of commencement of sales of the Units in the Initial Public Offering. Furthermore, Clear Street agreed (and any of its designees to whom the Representative Shares are issued agree) (i) to waive its redemption rights (or right to participate in any tender offer) with respect to such shares in connection with the completion of the Company's initial Business Combination and (ii) to waive its rights to liquidating distributions from the Trust Account with respect to such shares if the Company fails to complete a Business Combination within the Completion Window.

#### Note 8 — Shareholders' Deficit
***Preference Shares*** — The Company is authorized to issue a total of 1,000,000 preference shares at par value of $0.0001 each. As of March 31, 2026 and December 31, 2025, there were no preference 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. As of March 31, 2026 and December 31, 2025, there were 581,250 shares of Class A ordinary shares issued and outstanding, excluding 17,250,000 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 March 31, 2026 and December 31, 2025, there were 5,750,000 Class B ordinary shares issued and outstanding.

The Founder Shares will automatically convert into Class A ordinary shares concurrently with or immediately following 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 sub-divisions, share capitalizations, reorganizations, recapitalizations and the like, and subject to further adjustment as provided herein. In the case that additional Class A ordinary shares, or any other equity-linked securities, are issued or deemed issued in excess of the amounts sold in this offering and related to or in connection with the closing of the initial Business Combination, the ratio at which Class B ordinary shares convert into Class A ordinary shares will be adjusted (unless the holders of a majority of the outstanding Class B ordinary shares agree to waive such adjustment with respect to any such issuance or deemed issuance) so that the number of Class A ordinary shares issuable upon conversion of all Class B ordinary shares will equal, in the aggregate, 25% of the sum of (i) the total number of all Class A ordinary shares outstanding upon the completion of the Initial Public Offering (including any Class A ordinary shares issued pursuant to the underwriters' over-allotment option and excluding the Class A ordinary shares underlying the Private Placement Warrants issued to the Sponsor), plus (ii) all Class A ordinary shares and equity-linked securities issued or deemed issued, in connection with the closing of the initial Business Combination (excluding any shares or equity-linked securities issued, or to be issued, to any seller in the initial Business Combination and any private placement-equivalent warrants issued to the Sponsor or any of its affiliates or to the Company's officers or directors upon conversion of Working Capital Notes) minus (iii) any redemptions of Class A ordinary shares by Public Shareholders in connection with an initial Business Combination; provided that such conversion of Founder Shares will never occur on a less than one-for-one basis.

Except as set forth herein, 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. Unless specified in the amended and restated memorandum and articles of association or as required by the Companies Act or stock exchange rules, an ordinary resolution under Cayman Islands law and the amended and restated memorandum and articles of association, which requires the affirmative vote of at least a majority of the votes cast by such shareholders as, being entitled to do so, vote in person or, where proxies are allowed, by proxy at the applicable general meeting of the Company is generally required to approve any matter voted on by the Company's shareholders. Approval of certain actions requires a special resolution under Cayman Islands law, which (except as specified below) requires the affirmative vote of at least two-thirds of the votes cast by such shareholders as, being entitled to do so, vote in person or, where proxies are allowed, by

[**Table of Contents**](#TOC)

proxy at the applicable general meeting, and pursuant to the Company's amended and restated memorandum and articles of association, such actions include amending the amended and restated memorandum and articles of association and approving a statutory merger or consolidation with another company. There is no cumulative voting with respect to the appointment of directors, meaning, following the Company's initial Business Combination, the holders of more than 50% of the ordinary shares voted for the appointment of directors can elect all of the directors. Prior to the consummation of the initial Business Combination, only holders of the Class B ordinary shares will (i) have the right to vote on the appointment and removal of directors and (ii) be entitled to vote on continuing the Company in a jurisdiction outside the Cayman Islands (including any special resolution required to amend the constitutional documents or to adopt new constitutional documents, in each case, as a result of approving a transfer by way of continuation in a jurisdiction outside the Cayman Islands). Holders of the Class A ordinary shares will not be entitled to vote on these matters during such time. These provisions of the amended and restated memorandum and articles of association may only be amended if approved by a special resolution passed by the affirmative vote of at least 90% (or, where such amendment is proposed in respect of the consummation of the initial Business Combination, two-thirds) of the votes cast by such shareholders as, being entitled to do so, vote in person or, where proxies are allowed, by proxy at the applicable general meeting of the Company.

**Warrants —** As of March 31, 2026 and December 31, 2025, there were 5,867,240 warrants outstanding (including warrants that are constituent security of either the Units or the Private Placement Units), including 5,749,965 Public Warrants and 117,275 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 Public Warrant and will have no obligation to settle such Public Warrant exercise unless a registration statement under the Securities Act with respect to the Class A ordinary shares underlying the Public Warrants is then effective and a prospectus relating thereto is current. No Public Warrant will be exercisable and the Company will not be obligated to issue a Class A ordinary share upon exercise of a Public Warrant unless the Class A ordinary share issuable upon such Public 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 Public Warrants. In the event that the conditions in the two immediately preceding sentences are not satisfied with respect to a Public Warrant, the holder of such Public Warrant will not be entitled to exercise such Public Warrant and such Public Warrant may have no value and expire worthless. In no event will the Company be required to net cash settle any Public Warrant. In the event that a registration statement is not effective for the exercised Public Warrants, the purchaser of a Unit containing such Public Warrant will have paid the full purchase price for the Unit solely for the Class A ordinary share underlying such Unit.

Under the terms of the warrant agreement, the Company will agree that, as soon as practicable, but in no event later than 20 business days after the closing of its Business Combination, it will use 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 Public 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 Public Warrants until the expiration of the Public 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 Public Warrants is not effective by the sixtieth (60<sup>th</sup>) business day after the closing of the initial Business Combination, Public 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 Public 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 Public 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.

If the holders exercise their Public Warrants on a cashless basis, they would pay the warrant exercise price by surrendering the Public Warrants for that number of Class A ordinary shares equal to the quotient obtained by dividing (x) the product of the number of Class A ordinary shares underlying the Public Warrants, multiplied by the excess of the "fair market value" of the Class A ordinary shares over

[**Table of Contents**](#TOC)

the exercise price of the Public 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 Public 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 Public Warrants:

● in whole and not in part;

● at a price of $0.01 per Public Warrant;

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

● if, and only if, the closing price of the Class A ordinary shares equals or exceeds $18.00 per share (as adjusted for adjustments to the number of shares issuable upon exercise or the exercise price of a Public Warrant) for any 20 trading days within a 30- trading day period commencing at least 30 days after completion of the Company's initial Business Combination and ending three business days before the Company sends the notice of redemption to the Public 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 Public 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 9 — 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.

#### Overview
We are a blank check company incorporated on March 3, 2025 as a Cayman Island exempted company and formed for the purpose of effecting a merger, share exchange, asset acquisition, share purchase, reorganization or similar business combination with one or more businesses, which we refer to throughout this Quarterly Report as our "initial business combination". We intend to effectuate our initial business combination using cash from the proceeds of the Initial Public Offering and the sale of the Private Placement Units, the proceeds of the sale of our shares in connection with our initial business combination (pursuant to forward purchase agreements or backstop agreements we may enter into following the consummation of the Initial Public Offering or otherwise), shares issued to the owners of the target, debt issued to bank or other lenders or the owners of the target, or a combination of the foregoing.

On June 30, 2025, we consummated our Initial Public Offering of 17,250,000 Units, which includes the full exercise by the underwriters of their over-allotment option in the amount of 2,250,000 Units, at $10.00 per Unit, generating gross proceeds of $172,500,000. Simultaneously with the closing of the Initial Public Offering, we consummated the sale of 351,825 Private Placement Units, in a private placement to the Sponsor, at a price of $10.00 per Private Placement Unit, generating gross proceeds of $3,518,250.

We incurred offering costs of $9,424,463, consisting of $1,155,750 of cash underwriting fee, $5,175,000 of deferred underwriting fee (or $3,105,000 if in connection with the proposed Business Combination), $2,294,250 for issuance of representative shares, and $799,463 of other offering costs.

Upon the closing of the Initial Public Offering and the private placement, $173,362,500 ($10.05 per Unit) of the net proceeds of the sale of the Units and the Private Placement Units were placed in a U.S.-based trust account (the "Trust Account"), located in the United States with Continental Stock Transfer & Trust Company acting as trustee, and will be invested only in United States "government securities" within the meaning of Section 2(a)(16) of the Investment Company Act, having a maturity of 185 days or less or in money market funds meeting certain conditions under Rule 2a-7 promulgated under the Investment Company Act which invests only in direct U.S. government treasury obligations, as determined by us, until the earlier of: (i) the completion of an initial business combination and (ii) the distribution of the Trust Account as described below.

#### Proposed Business Combination
On August 25, 2025, the Company executed a Business Combination Agreement (the "Business Combination Agreement"), with YA S3 Inc., a Florida corporation and an indirect wholly owned subsidiary of the Company ("SPAC Sub"), Foris Holdings KY Limited, a Cayman Islands exempted company known commercially as Crypto.com ("Crypto.com"), Crypto.com Strategy Holdings, a Cayman Islands exempted company ("Crypto.com Sub"), Yorkville Acquisition Sponsor, LLC, a Delaware limited liability company ("Sponsor"), and Trump Media & Technology Group Corp., a Florida corporation ("TMTG" and together with Crypto.com Sub and the Sponsor, the "Sellers").

Pursuant to the terms of the Business Combination Agreement, the Sellers will contribute certain assets to the Company and SPAC Sub (as applicable) in exchange for Transaction Shares, the Forced Exercise Warrants and the Earnout Warrants (as applicable).

Pursuant to and concurrently with the Business Combination Closing, Crypto.com entered into the Pre-Closing Crypto.com Contribution Agreement 1 pursuant to which, immediately prior to, but contingent upon, the Business Combination Closing, Crypto.com will contribute (the "Pre-Closing Crypto.com Contribution") 6,313,000,212 Cronos tokens and all necessary physical devices required to establish and operate a Cronos proof of stake validator node and staking infrastructure (the "Cronos Assets") to Crypto.com Sub.

Pursuant to and concurrently with the execution of the Business Combination Agreement, Crypto.com Sub entered into an Asset Contribution Agreement with the Company (the "Crypto.com Contribution and Sale Agreement" and, together with the Crypto.com Pre-Closing Contribution Agreement 1, the "Crypto.com Contribution Agreements") pursuant to which, at the Business Combination Closing, (a) Crypto.com Sub will (1) at the Business Combination Closing, sell 90% of the Cronos Assets to SPAC Sub and (2) immediately following the Business Combination Closing, contribute 10% of the Cronos Assets to the Company in consideration of an aggregate 100,000,000 shares of SPAC Class B Common Stock, and a Forced Exercise Warrant, exercisable for 10,000,000 shares of SPAC Class A Common Stock. In connection with the consummation of the Crypto.com Contribution and Sale Agreement, at the Business Combination Closing, Crypto.com will license to the Company, pursuant to a Trademark License Agreement, certain intellectual property and all operational knowhow and proprietary technology required to establish and operate a Cronos proof of stake validator node, and staking infrastructure.

Pursuant to and concurrently with the execution and delivery of the Business Combination Agreement, TMTG entered into a trademark license agreement (the "TMTG License Agreement"), with Trump Media Group, LLC, a Florida limited liability company, ("Asset Company") pursuant to which, immediately prior to, but contingent upon, the Business Combination Closing, TMTG will license the rights to use the "Trump Media Group" brand name and certain other intellectual property rights to the Asset Company (the "Pre-Closing TMTG Contribution" and together with the Pre-Closing Crypto.com Contribution, the "Pre-Closing Contributions").

Pursuant to and concurrently with the execution and delivery of the Business Combination Agreement, TMTG entered into an asset contribution agreement with the Company (the "TMTG Contribution Agreement") and, together with the Crypto.com Contribution Agreements and the TMTG License Agreement, the "Contribution Agreements") pursuant to which, at the Business Combination Closing, TMTG will contribute 100% of the issued and outstanding membership interests of the Asset Company to the Company in consideration of 10,000,000 shares of SPAC Class A Common Stock, the Earnout Warrants (as described below) and a Forced Exercise Warrant, exercisable for 10,000,000 shares of SPAC Class A Common Stock.

At the Business Combination Closing, subject to the terms and conditions set forth in the Business Combination Agreement and pursuant to the Contribution Agreements, the Sellers will sell to the Company (or SPAC Sub, as applicable), and the Company (or SPAC Sub, as applicable) will purchase from the Sellers, the Cronos Assets and the Asset Company Interests (as applicable) as follows:

#### Results of Operations
As of March 31, 2026, we had not commenced any operations. All activity from inception through March 31, 2026 relates to our formation and our Initial Public Offering, and, since the completion of the Initial Public Offering, our search for a target to consummate an initial business combination. We will not generate any operating revenues until after the completion of an initial business combination, at the earliest. We will generate non-operating income in the form of interest and dividend income from the proceeds derived from the Initial Public Offering and placed in the Trust Account. We expect to incur increased 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 March 31, 2026, we had net income of $943,355, which consisted of income on investments held in the Trust Account of $1,594,402 and interest income of $1,230, offset by general and administrative expenses of $652,277.

For the period from March 3, 2025 (inception) through March 31, 2025, we had net loss of $30,424, which consisted of formation, general and administrative expenses.

#### Liquidity, Capital Resources and Going Concern
As of March 31, 2026, we had $60,261 in cash and cash equivalents held outside of the Trust Account and a working capital deficit of $2,258,970 (excluding cash and marketable securities held in the Trust Account and the deferred underwriter fee payable).

Until the consummation of the Initial Public Offering, our only source of liquidity was from the $25,000 of proceeds from our Sponsor's purchase of Class B ordinary shares, par value $0.0001 per share, and a loan of $124,723 from our Sponsor pursuant to a promissory note to cover certain expenses.

Following our Initial Public Offering and the sale of Private Placement Units to the Sponsor, a total of $173,362,500 was placed in the Trust Account.

For the three months ended March 31, 2026, net cash used in operating activities was $401,838. Net income of $943,355 was adjusted by income on investments in Trust Account of $1,594,402, and $249,209 changes in operating assets and liabilities. Net cash provided by financing activities was $250,000 related to proceeds from Working Capital Note to Sponsor.

As of March 31, 2026, we had marketable securities held in the Trust Account of $177,932,677 consisting of securities held in a money market fund that invests in U.S. Treasury securities with a maturity of 185 days or less. 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 deferred underwriting fees and income taxes payable), to complete our initial business combination. To the extent that our share capital or debt is used, in whole or in part, as consideration to complete our initial business combination, the remaining proceeds held in the Trust Account will be used as working capital to finance the operations of the target business or businesses, make other acquisitions and pursue our growth strategies.

As of March 31, 2026, we had cash and cash equivalents of $60,261 held outside the Trust Account. 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 an initial business combination.

[**Table of Contents**](#TOC)

We may need to raise additional funds in order to meet the expenditures required for operating our business prior to our initial business combination. We expect to incur significant costs related to identifying a target business, undertaking in-depth due diligence and negotiating an initial business combination. These conditions raise substantial doubt about our ability to continue as a going concern for a period of time within one year from the date that the financial statements accompanying this Quarterly Report on Form 10-Q are issued.

In order to fund working capital deficiencies or finance transaction costs in connection with an initial business combination, our Sponsor or an affiliate of our Sponsor or certain of our officers and directors may, but are not obligated to, loan us funds as may be required. If we complete an initial business combination, we may repay such loaned amounts out of the proceeds of the Trust Account released to us. In the event that an initial 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 Notes may be convertible into units of the post-business combination entity at a price of $10.00 per unit, at the option of the lender. As of March 31, 2026, there is $250,000 outstanding under the Working Capital Note.

#### Off-Balance Sheet Financing Arrangements
**We have no obligations, assets or liabilities, which would be considered off-balance sheet arrangements as of March 31, 2026. We do not participate in transactions that create relationships with unconsolidated entities or financial partnerships, often referred to as variable interest entities, which would have been established for the purpose of facilitating off-balance sheet arrangements. We have not entered into any off-balance sheet financing arrangements, established any special purpose entities, guaranteed any debt or commitments of other entities, or purchased any non-financial assets.**

#### Related Party Transactions

#### Please refer to Financial Statement Note 6 - Related Party Transactions.

#### Contractual Obligations
We do not have any long-term debt, capital lease obligations, operating lease obligations or long-term liabilities as of March 31, 2026.

The underwriters of the Initial Public Offering are entitled to a deferred underwriting discount of $0.30 per Unit, or $5,175,000. The deferred fee will become payable to the underwriters from the amounts held in the Trust Account solely in the event that we complete an initial business combination, subject to the terms of the underwriting agreement. On August 25, 2025, the underwriters agreed to reduce the deferred underwriting discount to $0.18 per Unit sold in the Initial Public Offering, or $3,105,000, in connection with the proposed Business Combination contemplated by the Business Combination Agreement. If the Company consummates a Business Combination other than the proposed Business Combination, the deferred underwriting discount will remain $0.30 per Unit, or $5,175,000.

#### Critical Accounting Estimates
The preparation of financial statements and related disclosures in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements, and income and expenses during the periods reported. Actual results could materially differ from those estimates. We have identified the following critical accounting policies:

**Warrant Instruments**

The Company accounts for the public warrants and private placement warrants issued in connection with the Initial Public Offering and the private placement in accordance with the guidance contained in Financial Accounting Standards Board ("FASB") ASC Topic 815, "Derivatives and Hedging". Accordingly, the Company evaluated and recorded the warrant instruments under equity treatment at their assigned values. The fair value of Public Warrants was determined using Black-Scholes Simulation Model. The Public Warrants have

[**Table of Contents**](#TOC)

been classified within shareholders' deficit and will not require remeasurement after issuance. The key inputs used in the valuation of the Public Warrants are as follows:

---

| | |
|:---|:---|
|  | **June 30, 2025** |
| Implied Class A Ordinary Share price | $11.02 |
| Exercise price | $11.50 |
| Simulation term (years) | 7.00 |
| Risk-free rate | 3.98% |
| Selected volatility | 2.77% |
| Calculated value per warrant | $0.61 |
| Market adjustment | 29.26% |

**Accounting Standards Not Yet Adopted**

In November 2024, the FASB issued Accounting Standards Update ("ASU") 2024-03, "Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures" ("ASU 2024-03"), which requires entities to disclose details about specific expenses, such as inventory purchases, employee compensation, depreciation, amortization and depletion, included within commonly presented income statement expense captions. The disaggregated expense captions must be disclosed in a tabular format in the notes to the financial statements. ASU 2024-03 is effective for annual periods beginning on January 1, 2027 and interim periods beginning on January 1, 2028. The Company is currently evaluating the impact of adopting ASU 2024-03 on its financial statements and related disclosures.

In December 2025, the FASB issued Accounting Standards Update ("ASU") 2025-11, Interim Reporting (Topic 270): Narrow-Scope Improvements ("ASU 2025-11"), which clarifies the guidance in Topic 270 to improve the consistency of interim financial reporting. The ASU provides a comprehensive list of required interim disclosures and introduces a disclosure principle requiring entities to disclose events since the end of the last annual reporting period that have a material impact on the entity. ASU 2025-11 is effective for fiscal years beginning after December 15, 2027, including interim periods within those fiscal years, with early adoption permitted. The Company is currently evaluating the impact of adopting ASU 2025-11 on its consolidated financial statements and related disclosures.

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

#### Item 4. Controls and Procedures Evaluation of Disclosure Controls and Procedures

#### Evaluation of Disclosure Controls and Procedures
Disclosure controls and procedures are designed to ensure that information required to be disclosed by us in our Exchange Act reports is recorded, processed, summarized, and reported within the time periods specified in the SEC's rules and forms, and that such information is accumulated and communicated to our management, including our principal executive officer and principal financial officer or persons performing similar functions, as appropriate to allow timely decisions regarding required disclosure.

Under the supervision and with the participation of our management, including our principal executive officer and principal financial and accounting officer, we conducted an evaluation of the effectiveness of our disclosure controls and procedures as of the end of the fiscal quarter ended March 31, 2026, as such term is defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act. Based on this evaluation, our principal executive officer and principal financial and accounting officer have concluded that during the period covered by this report, our disclosure controls and procedures were effective at a reasonable assurance level and, accordingly, provided reasonable assurance that the information required to be disclosed by us in reports filed under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC's rules and forms.

#### Changes in Internal Control over Financial Reporting
There were no changes in our internal control over financial reporting that occurred during the quarter ended March 31, 2026, covered by this Quarterly Report on Form 10-Q that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

#### Item 1A. Risk Factors.
As of the date of this Report, there have been no material changes to the risk factors disclosed in our annual report on Form 10-K filed with the SEC on March 31, 2026. We may disclose changes to such factors or disclose additional factors from time to time in our future filings with the SEC.

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

As disclosed in Items 1.01, 2.03, and 3.02 of the Company's Current Report on Form 8-K filed on February 17, 2026, the Company issued a Working Capital Note on February 11, 2026, in the aggregate principal amount of $250,000 to the Sponsor (*See Note 6 – Related Party Transactions*). Pursuant to the terms of the Working Capital Note, the principal balance shall not accrue interest; shall be payable by the Company on the earlier of the date on which Company consummates its initial Business Combination or the date that the winding up of the Company is effective; and is convertible at the Sponsor's election upon the consummation of the Company's initial Business Combination. Should the Sponsor elect to convert all or a portion of the principal balance, the elected principal balance amount will convert, at a price of $10.00 per unit, into Working Capital Units, rounded down to the nearest whole number. The Company has relied upon Section 4(a)(2) of the Securities Act of 1933, as amended, in connection with the issuance of the Working Capital Note.

On February 19, 2026, the Company drew $250,000 against the Working Capital Note. As of March 31, 2026, there is $250,000 outstanding under the Working Capital Note. Other than the issuance of the Working Capital Note, no unregistered sales of equity securities were completed by the Company during the fiscal quarter ending on March 31, 2026.

As disclosed in Items 1.01 and 3.02 of the Company's Current Report on Form 8-K filed on August 26, 2025, the Company entered into a Business Combination Agreement and related agreements that contemplate the issuance, at the closing of the Business Combination, of shares of the Company's capital stock and warrants to certain counterparties as transaction consideration and in related financing arrangements. These contemplated issuances are subject to customary closing conditions and have not occurred as of the date of this report. Accordingly, no securities have been issued, no proceeds have been received, and no sales of the Company's securities have taken place in connection with the Business Combination Agreement and related agreements during the period covered by this report.

If and when the closing of the proposed Business Combination occurs, the Company expects that any such issuances will be made in private transactions in reliance on exemptions from registration under the Securities Act of 1933, as amended, including Section 4(a)(2) and, where applicable, Regulation D and/or Regulation S. Any unregistered sales that occur immediately before, at, or after the closing of the Business Combination will be reported in the Company's periodic reports covering the period in which such issuances occur and/or in a Current Report on Form 8-K, as appropriate.

*Use of Proceeds*

On June 30, 2025, the Company consummated its Initial Public Offering of 17,250,000 units, including 2,250,000 units issued pursuant to the underwriters' full exercise of their over-allotment option, at a price of $10.00 per unit, generating gross proceeds of $172,500,000. Simultaneously with the closing of the offering, the Company consummated the private placement to the Sponsor of 351,825 private placement units at a price of $10.00 per unit, for aggregate gross proceeds of $3,518,250. Each private placement unit consists of one Class A ordinary share and one-third of one redeemable warrant, each whole warrant exercisable to purchase one Class A ordinary share at $11.50 per share. After deducting the underwriting discounts and commissions paid at closing and offering expenses, an aggregate of $173,362,500 ($10.05 per unit) from the sale of the units in the offering and the private placement units was placed in a trust account (the "Trust Account") maintained by Continental Stock Transfer & Trust Company, as trustee.

[**Table of Contents**](#TOC)

As of March 31, 2026, the net proceeds from the offering and the concurrent private placement remain on deposit in the trust account in accordance with the Company's governing documents and the terms disclosed at the time of the offering, pending completion of the Company's initial business combination. Consistent with the Company's governing documents and the trust agreement, funds in the Trust Account have been invested only in U.S. government securities with a maturity of 185 days or less, in money market funds meeting the conditions of Rule 2a-7 under the Investment Company Act that invest solely in direct U.S. government obligations, as uninvested cash, or in an interest-bearing demand deposit or other bank account. Other than permitted withdrawals for taxes and allowed expenses, there has been no material change in the planned use of proceeds as described in the Company's final prospectus. As of March 31, 2026, the Trust Account contains $177,932,677.
