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 June 30, 2026, the Company has not commenced any operations. All activity for the period from March 3, 2025 (inception) through June 30, 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 investments 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 fees, $5,175,000 of deferred underwriting fees (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

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,

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.

Termination of 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”). The Company, SPAC Sub, Crypto.com, Crypto.com Sub, TMTG and the Sponsor are referred to herein as the “Parties.”

On August 7, 2026, the Parties entered into a Mutual Termination and Release Agreement (the “Termination Agreement”), pursuant to which the Business Combination Agreement was terminated by the mutual consent of the Parties, effective as of August 7, 2026, due to market conditions. As a result of the mutual termination of the Business Combination Agreement, that agreement became of no further force and effect, except as set forth in the Termination Agreement. The mutual termination of the Business Combination Agreement also terminated and made void the transaction agreements that were entered into in connection with the Business Combination Agreement.

Liquidity, Capital Resources and Going Concern

As of June 30, 2026, the Company had $181,617 of cash and a working capital deficit of $2,400,448. 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 until June 27, 2027 to consummate a Business Combination. It is uncertain that the Company will be able to consummate a Business Combination by this time. If a Business Combination is not consummated by this date, there will be a mandatory liquidation and subsequent dissolution.

Further, the Company has incurred and expects to continue to incur significant costs in pursuit of a Business Combination. In connection with the Company’s assessment of going concern considerations in accordance with Accounting Standards Update (“ASU”) 2014-15, “Disclosures of Uncertainties about an Entity’s Ability to Continue as a Going Concern,” management has determined that these conditions raise substantial doubt about the Company’s ability to continue as a going concern. In addition, if the Company is unable to complete a Business Combination within the Combination Period (by June 27, 2027), the Company’s board of directors would proceed to commence a voluntary liquidation and thereby a formal dissolution of the Company. There is no assurance that the Company’s plans to consummate a Business Combination will be successful within the Combination Period. As a result, management has determined that such an additional condition also raises substantial doubt about the Company’s ability to continue as a going concern. The financial statements do not include any adjustments that might result from the outcome of this uncertainty.
