Item 4.

Purpose of Transaction

In September 2025, Mr. Rosenfeld acquired an aggregate of 7,666,667 ordinary shares (?founder shares?) in exchange for a total capital contribution of $25,000. Thereafter, he transferred certain shares to other holders leaving him with an aggregate of 2,782,617 founder shares. On January 26, 2026, the Issuer consummated its initial public offering (?IPO?) of 23,000,000 of its units (?Units?), including 3,000,000 Units subject to the underwriters? over-allotment option. Each Unit consists of one ordinary share of the Issuer and one-third of one redeemable warrant (?Warrant?), with each Warrant entitling the holder to purchase one ordinary share for $11.50. The Units were sold at an offering price of $10.00 per Unit, generating gross proceeds of $230,000,000. Simultaneously with the consummation of the IPO, the Issuer consummated the private placement (?Private Placement?) of 550,000 units (?Private Placement Units?) at a price of $10.00 per Private Placement Unit, generating total proceeds of $5,500,000. Mr. Rosenfeld purchased 5,600 Private Placement Units in such Private Placement. The Private Placement Units are identical to the Units included in the Units sold in the IPO. Mr. Rosenfeld agreed not to transfer, assign, or sell any of the Private Placement Units (or underlying securities) he purchased (except to certain transferees) until the completion of the Issuer?s initial business combination. Mr. Rosenfeld is the Chief SPAC Officer of the Issuer and has beneficial ownership of approximately 8.9% of the outstanding ordinary shares of the Issuer. Mr. Rosenfeld may later acquire additional securities of the Issuer including upon exercise of the Warrants included in the Private Placement Units purchased by him as described above. Any actions Mr. Rosenfeld might undertake with respect to the ordinary shares may be made at any time and from time to time without prior notice and will be dependent upon his review of numerous factors, including, but not limited to: an ongoing evaluation of the Issuer?s business, financial condition, operations and prospects; price levels of the Issuer?s securities; general market, industry and economic conditions; the relative attractiveness of alternative business and investment opportunities; and other future developments relating to him personally. As of the date of this Schedule 13D, except as set forth in this Schedule 13D above, Mr. Rosenfeld does not have any plans or proposals which would result in: (a) The acquisition by any person of additional securities of the Issuer, or the disposition of securities of the Issuer; (b) An extraordinary corporate transaction, such as a merger, reorganization or liquidation, involving the Issuer or any of its subsidiaries; (c) A sale or transfer of a material amount of assets of the Issuer or any of its subsidiaries; (d) Any change in the present board of directors or management of the Issuer, including any plans or proposals to change the number or term of the board of directors or management of the Issuer; (e) Any material change in the present capitalization or dividend policy of the Issuer; (f) Any other material change in the Issuer?s business or corporate structure; (g) Changes in the Issuer?s charter, bylaws or instruments corresponding thereto or other actions which ay impede the acquisition of control of the Issuer by any person; (h) Causing a class of securities of the Issuer to be delisted from a national securities exchange or to cease to be authorized to be quoted in an inter-dealer quotation system of a registered national securities association; (i) A class of equity securities of the Issuer becoming eligible for termination of registration pursuant to Section 12(g)(4) of the Act; or (j) Any action similar to any of those actions enumerated above.
