Item 8.01 Other Events

As previously disclosed by the Company in its Current Report on Form 8-K, as filed with the U.S. Securities and Exchange Commission (the “SEC”) on July 7, 2026 (the “IPO Closing 8-K”), the Company consummated its initial public offering (the “IPO”) on July 6, 2026, resulting in the issuance of an aggregate 23,000,000 units (the “Units”). Each Unit consists of one Class A ordinary share of the Company, par value $0.0001 per share (each, an “Ordinary Share”), and one-third of one redeemable warrant of the Company (a “Public Warrant”), with each whole Public Warrant entitling the holder thereof to purchase one Ordinary Share at a price of $11.50 per share, subject to adjustment. The Units were sold at a price of $10.00 per Unit, and the IPO generated gross proceeds to the Company of $230,000,000.

Simultaneously with the closing of the IPO, the Company completed the private sale and issuance of an aggregate of 610,000 private placement units (the “Private Placement Units”), consisting of the sale and issuance of (i) 300,000 Private Placement Units to Viking Acquisition Sponsor II, LLC (the “Sponsor”) at a price of $10.00 per unit under the Private Placement Units Purchase Agreement, by and between the Company and the Sponsor, generating gross proceeds to the Company of $3,000,000 and (ii) 310,000 Private Placement Units to Cohen & Company Capital Markets, a Division of Cohen & Company Securities, LLC (“Cohen”) at a price of $10.00 per unit under the Underwriter Private Placement Units Purchase Agreement, by and between the Company and Cohen, generating gross proceeds to the Company of $3,100,000, for aggregate gross proceeds to the Company of $6,100,000. Each Private Placement Unit consisted of one Ordinary Share and one-third of one redeemable warrant of the Company (a “Private Placement Warrant”), with each whole Private Placement Warrant entitling the holder thereof to purchase one Ordinary Share at a price of $11.50 per share, subject to adjustment. The Private Placement Units (and underlying securities) are identical to the Units sold in the IPO, except as otherwise disclosed in the Registration Statement. No underwriting discounts or commissions were paid with respect to such sale. The issuance of the Private Placement Units was made pursuant to the exemption from registration contained in Section 4(a)(2) of the Securities Act of 1933, as amended.

A total of $230,000,000, consisting of the entirety of the proceeds received by the Company after deduction for commissions from the IPO and some proceeds from the sale of the Private Placement Units, were placed in a U.S.-based trust account at JPMorgan Chase Bank, N.A. maintained by Continental Stock Transfer & Trust Company, acting as trustee. 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, the funds in the trust account will not be released from the trust account until the earliest to occur of: (a) the completion of our initial business combination (including the release of funds to pay any amounts due to any public shareholders who properly exercise their redemption rights in connection therewith), (b) the redemption of any public shares properly submitted in connection with a shareholder vote to approve an amendment to our amended and restated memorandum and articles of association (A) in a manner that would affect the substance or timing of our obligation to redeem 100% of the Company’s public shares if the Company does not complete an initial business combination within the completion window or (B) with respect to any other provision relating to the rights of holders of Ordinary Shares or pre-initial business combination activity, or (c) the redemption of the Company’s public shares if the Company is unable to complete its initial business combination within the completion window, subject to applicable law.

An audited balance sheet as of July 6, 2026, reflecting receipt of the proceeds upon consummation of the IPO and the Private Placement Units has been issued by the Company and is included as Exhibit 99.1 to this Current Report on Form 8-K.
