The Units were sold at a price of $10.00 per Unit, generating gross proceeds to the Company of $276,000,000. Each Unit consists of one Class A ordinary share, par value $0.0001 per share (the “Class A Ordinary Share”) and one right to receive one-tenth (1/10th) of one Class A ordinary share (the “Right”) of the Company.

In connection with the IPO, the Company entered into the following agreements, forms of which were previously filed as exhibits to the registration statement on Form S-1 (File No. 333-285648) for the IPO, which was originally filed with the U.S. Securities and Exchange Commission on August 20, 2024 (as amended, the “Registration Statement”):

Simultaneously with the closing of the IPO, pursuant to the Private Placement Units Purchase Agreement, the Company completed the private placement of an aggregate of 338,000 units (the “Private Placement Units”) to the Sponsor at $10.00 per Unit, each Unit consisting of one Class A Ordinary Share and one Right of the Company.

The Private Placement Units are identical to the Units sold in the IPO, except that the Private Units are subject to transfer restrictions. The Sponsor and Santander US Capital Markets LLC were granted certain demand and piggyback registration rights in connection with the purchase of the Private Placement Units.

The Private Placement Units were issued pursuant to Section 4(a)(2) of the Securities Act of 1933, as amended, as the transactions did not involve a public offering.

Item 5.03. Amendments to Certificate of Incorporation or Bylaws; Change in Fiscal Year.

On March 31, 2025, in connection with the IPO, the Company filed its amended and restated memorandum and articles of association (the “Amended and Restated Memorandum and Articles of Association”) with the Cayman Islands Registrar of Companies, which was effective on March 31, 2025. The terms of the Amended and Restated Memorandum and Articles of Association are set forth in the Registration Statement and are incorporated herein by reference. A copy of the Amended and Restated Memorandum and Articles of Association is attached as Exhibit 3.1 hereto and incorporated herein by reference.

Item 8.01. Other Events.

A total of $277,380,000, comprised of the proceeds from the IPO and the sale of the Private Placement Units, was placed in a U.S.-based trust account maintained by Continental Stock Transfer & Trust Company, acting as trustee. Except with respect to interest earned on the funds held in the trust account (which interest shall be net of permitted withdrawals and less up to $100,000 of interest to pay dissolution expenses), the funds held in the trust account will not be released from the trust account until the earliest of (i) the completion of the initial business combination, (ii) the redemption of the public shares if the Company is unable to complete its initial business combination within the completion window, subject to applicable law, or (iii) the redemption of the 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 Company’s 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.
