On August 27, 2026, Southern Cross Acquisition II Corp., a Cayman Islands exempted company (the “Company”) consummated its initial public offering (the “IPO”) of 7,652,630 units (the “Units”), which includes the partial exercise of the underwriters’ option to purchase an additional 152,630 Units to cover over-allotments. Each Unit consists of one ordinary share, $0.0001 par value per share (each, a “Ordinary Share”), one redeemable warrant (the “Warrant”), each Warrant entitling the holder thereof to purchase one Ordinary Share at an exercise price of $11.50 per share, and one right (each, a “Right”), each Right entitling the holder thereof to receive one-fourth of one Ordinary Share upon the completion of the Company’s initial business combination. The Units were sold at an offering price of $10.00 per Unit, generating gross proceeds of $76,526,300.

Substantially concurrently with the closing of the IPO, the Company completed the private sale of an aggregate of 224,932 units (the “Private Units”) to the Company’s Sponsor, Southern Cross Acquisition II Sponsor Corp., a Cayman Islands exempted company (the “Sponsor”), and D. Boral Capital LLC, the representative of the underwriters of the IPO (the “Representative”). Each Private Unit consists of one Ordinary Share, one Warrant (the “Private Warrants”), and one Right (the “Private Rights”). The Private Units are identical to the Units sold in the IPO, subject to limited exceptions as further described in the Registration Statement on Form S-1 (File No. 333-297331). The Private Units were sold at $10.00 per Unit, generating gross proceeds of $2,249,320.

A total of $76,717,616, from the proceeds of the IPO and the sale of the Private Units (net of transaction expenses and working capital) were placed in the Company’s trust account established for the benefit of the Company’s public shareholders and the underwriters of the IPO with Equiniti Trust Company, LLC acting as trustee.

An audited balance sheet as of August 27, 2026, reflecting receipt of the proceeds upon consummation of the IPO and the sale of Private Units has been issued by the Company and is included as Exhibit 99.1 to this Current Report on Form 8-K.
