Item 2. Unregistered Sales of Equity Securities and Use of Proceeds from Registered Securities

On May 21, 2026, the Company consummated the IPO of 7,500,000 Class A ordinary shares (the “Public Shares”). The Public Shares were sold at an offering price of $10.00 per Public Share, generating gross proceeds of $75,000,000 (before underwriting discounts and commission and offering expenses). The securities sold in the IPO were sold pursuant to a registration statement on Form

(File No.:

The registration statement became effective on May 19, 2026.

On May 21, 2026, substantially concurrently with the closing of the IPO, the Company consummated the private placement (“Private Placement”) of 275,000 Private Placement Shares with the Sponsor at a price of $10.00 per Private Placement Share, generating total proceeds of $2,750,000. The Private Placement Shares are identical to the Public Shares, being Class A ordinary shares, sold in the IPO except with respect to certain registration rights and transfer restrictions. Additionally, the holders of the Private Placement Shares have agreed to certain restrictions on the Private Placement Shares, as described in the Registration Statement. Such holders agreed not to transfer, assign or sell any of the Private Placement Shares (except in limited circumstances, as described in the Registration Statement) until 30 days after the completion of the Company’s initial business combination. The holders were granted certain demand and piggyback registration rights in connection with the purchase of the Private Placement Shares.

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