Item 8.01. Other Events.

As previously reported, on June 30, 2025, Yorkville Acquisition Corp. (the “Company”) consummated its initial public offering (“IPO”) of 17,250,000 units (the “Units”), including 2,250,000 Units issued pursuant to the exercise of the underwriters’ over-allotment option. Each Unit consists of one Class A ordinary share of the Company, par value $0.0001 per share (the “Class A Ordinary Shares”), and one-third of one redeemable warrant of the Company (each, a “Warrant”), with each whole Warrant entitling the holder thereof to purchase one Class A Ordinary Share for $11.50 per share. The Units were sold at a price of $10.00 per Unit, generating gross proceeds to the Company of $172,500,000.

Also as previously reported, on June 30, 2025, simultaneously with the closing of the IPO, the Company completed the private sale of an aggregate of aggregate of 351,825 private placement units (the “Private Units”) to the Yorkville Acquisition Sponsor LLC at a purchase price of $10.00 per Private Unit, generating aggregate gross proceeds to the Company of $3,518,250. The Private Units are identical to the Units sold in the IPO, except as otherwise disclosed in the Company’s Registration Statements on Form S-1 (File No. 333-286569) for the IPO, originally filed with the U.S. Securities and Exchange Commission on April 16, 2025 (as amended, the “Registration Statement”).

A total of $173,362,500 of the proceeds from the IPO and the sale of the Private Units were placed in a U.S.-based trust account with Continental Stock Transfer & Trust Company, acting as trustee.

An audited balance sheet as of June 30, 2025 reflecting receipt of the proceeds upon consummation of the IPO and the sale of the Private Units has been issued by the Company and is included as Exhibit 99.1 to this Current Report on Form 8-K.
