Additional Information and Where to Find It

The Company intends to file with the Securities and Exchange Commission (the “SEC”) a Registration Statement on Form S-4 (as may be amended, the “Registration Statement”), which will include a preliminary proxy statement of the Company and a prospectus (the “Proxy Statement/Prospectus”) in connection with the Transactions. The definitive proxy statement and other relevant documents will be mailed to shareholders of the Company as of a record date to be established for voting on the Transactions and other matters as described in the Proxy Statement/Prospectus. The Company will also file other documents regarding the Transactions with the SEC. This Current Report on Form 8-K does not contain all of the information that should be considered concerning the Transactions and is not intended to form the basis of any investment decision or any other decision in respect of the Transactions. BEFORE MAKING ANY VOTING OR INVESTMENT DECISION, SHAREHOLDERS OF THE COMPANY AND OTHER INTERESTED PARTIES ARE URGED TO READ, WHEN AVAILABLE, THE PRELIMINARY PROXY STATEMENT/PROSPECTUS, AND AMENDMENTS THERETO, AND THE DEFINITIVE PROXY STATEMENT/PROSPECTUS AND ALL OTHER RELEVANT DOCUMENTS FILED OR THAT WILL BE FILED WITH THE SEC IN CONNECTION WITH THE COMPANY’S SOLICITATION OF PROXIES FOR THE EXTRAORDINARY GENERAL MEETING OF ITS SHAREHOLDERS TO BE HELD TO APPROVE THE TRANSACTIONS AND OTHER MATTERS AS DESCRIBED IN THE PROXY STATEMENT/PROSPECTUS BECAUSE THESE DOCUMENTS WILL CONTAIN IMPORTANT INFORMATION ABOUT THE COMPANY AND THE TRANSACTIONS. Investors and security holders will also be able to obtain copies of the Registration Statement and the Proxy Statement/Prospectus and all other documents filed or that will be filed with the SEC by the Company, without charge, once available, on the SEC’s website at www.sec.gov or by directing a request to: Yorkville Acquisition Corp., 1012 Springfield Avenue, Mountainside, New Jersey 07092; e-mail: YORK@mzgroup.us.

NEITHER THE SEC NOR ANY STATE SECURITIES REGULATORY AGENCY HAS APPROVED OR DISAPPROVED THE TRANSACTIONS DESCRIBED HEREIN, PASSED UPON THE MERITS OR FAIRNESS OF THE TRANSACTIONS OR ANY RELATED TRANSACTIONS OR PASSED UPON THE ADEQUACY OR ACCURACY OF THE DISCLOSURE IN THIS CURRENT REPORT. ANY REPRESENTATION TO THE CONTRARY CONSTITUTES A CRIMINAL OFFENSE.

A list of the names of such persons, and information regarding their interests in the Transactions and their ownership of the Company’s securities are, or will be, contained in the Company’s filings with the SEC. Additional information regarding the interests of the persons who may, under SEC rules, be deemed participants in the solicitation of proxies of the Company’s shareholders in connection with the Transactions, including the names and interests of the Company’s directors and executive officers, will be set forth in the Registration Statement and Proxy Statement/Prospectus, which is expected to be filed by the Company with the SEC. Investors and security holders may obtain free copies of these documents as described above.

Forward-Looking Statements:

This Current Report contains certain forward-looking statements within the meaning of the U.S. federal securities laws with respect to the Transactions involving the Company, including expectations, hopes, beliefs, intentions, plans, prospects, financial results or strategies regarding the Company and the Transactions and statements regarding the anticipated benefits and timing of the completion of the Transactions, the assets held by the Company, the price and volatility of Cronos, Cronos’ prominence as a digital asset and as the foundation of a new financial system, the Company’s listing on any securities exchange, the macro conditions surrounding Cronos, the planned business strategy, plans and use of proceeds, objectives of management for future operations of the Company, the upside potential and opportunity for investors, the Company’s plan for value creation and strategic advantages, market size and growth opportunities, regulatory conditions, technological and market trends, future financial condition and performance and expected financial impacts of the Transactions, the satisfaction of closing conditions to the Transactions and the level of redemptions of the Company’s public shareholders, and the Company’s expectations, intentions, strategies, assumptions or beliefs about future events, results of operations or performance or that do not solely relate to historical or current facts.

Forward-looking statements are predictions, projections and other statements about future events or conditions that are based on current expectations and assumptions and, as a result, are subject to risks and uncertainties. Many factors could cause actual future events to differ materially from the forward-looking statements in this communication, including, but not limited to: the risk that the Transactions may not be completed in a timely manner or at all, which may adversely affect the price of the Company’s securities; the risk that the Transactions may not be completed by the Company’s business combination deadline; the failure by the parties to satisfy the conditions to the consummation of the Transactions, including the approval of the Company’s shareholders; failure to realize the anticipated benefits of the Transactions; the level of redemptions of the Company’s public shareholders which may reduce the public float of, reduce the liquidity of the trading market of, and/or maintain the quotation, listing, or trading of the Class A ordinary shares of the Company or the shares of Class A common stock of the Company; the lack of a third-party fairness opinion in determining whether or not to pursue the Transactions; the failure of the Company to obtain or maintain the listing of its securities on any securities exchange after closing of the Transactions; costs related to the Transactions and as a result of becoming a public company; changes in business, market, financial, political and regulatory conditions; risks relating to the Company’s anticipated operations and business, including the highly volatile nature of the price of CRO; the risk that the Company’s stock price will be highly correlated to the price of CRO and the price of CRO may decrease between the signing of the definitive documents for the Transactions and the closing of the Transactions or at any time after the closing of the Transactions; risks related to increased competition in the industries in which the Company will operate; risks relating to significant legal, commercial, regulatory and technical uncertainty regarding CRO; risks relating to the treatment of crypto assets for U.S. and foreign tax purposes; risks that after consummation of the Transactions, the Company experiences difficulties managing its growth and expanding operations; the risks that growing the Company’s validator operations could be difficult; challenges in implementing our business plan including operating a Cronos validator, due to operational challenges, significant competition and regulation; being considered to be a “shell company” by any stock exchange on which the Company’s Class A common stock will be listed or by the SEC, which may impact the Company’s ability to list its Class A common stock and restrict reliance on certain rules or forms in connection with the offering, sale or resale of securities; the outcome of any potential legal proceedings that may be instituted against the Company or others following announcement of the Transactions, and those risk factors discussed in documents that the Company filed, or that will be filed, with the SEC.

The foregoing list of risk factors is not exhaustive. You should carefully consider the foregoing factors and the other risks and uncertainties described in the “Risk Factors” section of the final prospectus of the Company dated as of June 26, 2025 and filed by the Company with the SEC on June 30, 2025, the Company’s Quarterly Reports on Form 10-Q, the Registration Statement that will be filed by the Company and the Proxy Statement/Prospectus contained therein, and other documents filed by the Company from time to time with the SEC. These filings do or will identify and address other important risks and uncertainties that could cause actual events and results to differ materially from those contained in the forward-looking statements. There may be additional risks that the Company presently knows or that the Company currently believes are immaterial that could also cause actual results to differ from those contained in the forward-looking statements.

Forward-looking statements speak only as of the date they are made. Readers are cautioned not to put undue reliance on forward-looking statements, and the Company assumes no obligation and does not intend to update or revise these forward-looking statements, whether as a result of new information, future events, or otherwise. The Company gives no assurance that it will achieve its expectations.
