The prospectus constituting Part I of the Registration Statement has been omitted.

**PART II**<br>**INFORMATION NOT REQUIRED IN PROSPECTUS**

**Item 13. *Other Expenses of Issuance and Distribution.***

The estimated expenses payable by us in connection with the offering described in this registration statement (other than the underwriting discounts and commissions) will be as follows:

---

| | |
|:---|:---|
| Legal fees and expenses | $300000 |
| Accounting fees and expenses | $50000 |

---

(1) This amount represents the approximate amount of annual director and officer liability insurance premiums the registrant anticipates paying following the completion of its initial public offering and until it completes a business combination.

**Item 14. *Indemnification of Directors and Officers*.**

Cayman Islands law does not limit the extent to which a company's memorandum and articles of association may provide for indemnification of officers and directors, except to the extent any such provision may be held by the Cayman Islands courts to be contrary to public policy, such as to provide indemnification against willful default, willful neglect, civil fraud or the consequences of committing a crime. Our amended and restated memorandum and articles of association will provide for indemnification of our officers and directors to the maximum extent permitted by law, including for any liability incurred in their capacities as such, except through their own actual fraud, willful default or willful neglect. We expect to purchase a policy of directors' and officers' liability insurance that insures our officers and directors against the cost of defense, settlement or payment of a judgment in some circumstances and insures us against our obligations to indemnify our officers and directors.

Our officers and directors have agreed to waive any right, title, interest or claim of any kind in or to any monies in the trust account, and have agreed to waive any right, title, interest or claim of any kind they may have in the future as a result of, or arising out of, any services provided to us and will not seek recourse against the trust account for any reason whatsoever (except to the extent they are entitled to funds from the trust account due to their ownership of public shares). Accordingly, any indemnification provided will only be able to be satisfied by us if (i) we have sufficient funds outside of the trust account or (ii) we consummate an initial business combination.

We believe that these provisions, the insurance and the indemnity agreements are necessary to attract and retain talented and experienced officers and directors.

Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers or persons controlling us pursuant to the foregoing provisions, we have been informed that in the opinion of the SEC such indemnification is against public policy as expressed in the Securities Act and is therefore unenforceable.

We will enter into indemnity agreements with each of our officers and directors to provide contractual indemnification in addition to the indemnification provided for in our amended and restated memorandum and articles of association, a form of which is to be filed as an exhibit to this Registration Statement. These agreements will require us to indemnify these individuals to the fullest extent permitted under Cayman Islands law and to advance expenses incurred as a result of any proceeding against them as to which they could be indemnified.

Pursuant to the Underwriting Agreement to be filed as Exhibit 1.1 to this Registration Statement, we have agreed to indemnify the underwriters and the underwriters have agreed to indemnify us against certain civil liabilities that may be incurred in connection with this offering, including certain liabilities under the Securities Act.

**Item 15. *Recent Sales of Unregistered Securities.***

On September 30, 2025, Alfa 30 Limited, our Sponsor, acquired an aggregate of 3,833,333 ordinary shares ("founder shares") in exchange for a total capital contribution of $25,000 (or $0.0065 per share). Up to 500,000 founder shares are subject to forfeiture if the underwriters' over-allotment is not exercised in full or in part. On October 9, 2025 we also entered into a subscription agreement to issue to EarlyBirdCapital, Inc. and its designees an aggregate of 250,000 ordinary shares for an aggregate purchase price of approximately $1,630, or approximately $0.0065 per share. Such securities were issued pursuant to the exemption from registration contained in Section 4(a)(2) of the Securities Act.

Additionally, our initial shareholders, including the Sponsor, and EBC have agreed that they and/or their designees will purchase an aggregate of 350,000 Private Placement Units (250,000 Private Placement Units to be purchased by the Sponsor and 100,000 Private Placement Units to be purchased by EBC and its designees). Additionally, our initial shareholders, including the Sponsor, and EBC have agreed that if the over-allotment option is exercised by the underwriters in full or in part, they and/or their designees will purchase from the Company up to an additional 30,000 Private Placement Units at a price of $10.00 per unit in an amount that is necessary to maintain in the Trust Account $10.00 per unit sold to the public in this offering. These purchases will take place on a private placement basis simultaneously this offering. The issuance will be made pursuant to the exemption from registration contained in Section 4(a)(2) of the Securities Act.

No underwriting discounts or commissions were paid with respect to such sales.

**Item 16. *Exhibits and Financial Statement Schedules.***

(a) Exhibits. The list of exhibits immediately preceding the signature page of this registration statement is incorporated herein by reference.

(b) Financial Statements. See page F-1 for an index to the financial statements and schedules included in the registration statement.

**Item 17. *Undertakings*.**

(a) The undersigned registrant hereby undertakes to provide to the underwriters at the closing specified in the underwriting agreement, certificates in such denominations and registered in such names as required by the underwriters to permit prompt delivery to each purchaser.

(b) Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Act and will be governed by the final adjudication of such issue.

(c) The undersigned registrant hereby undertakes that:

&nbsp;&nbsp;&nbsp;&nbsp;(1) For purposes of determining any liability under the Securities Act of 1933, the information omitted from the form of prospectus filed as part of this registration statement in reliance upon Rule 430A and contained in a form of prospectus filed by the registrant pursuant to Rule 424(b)(1) or (4) or 497(h) under the Securities Act shall be deemed to be part of this registration statement as of the time it was declared effective.

&nbsp;&nbsp;&nbsp;&nbsp;(2) For the purpose of determining any liability under the Securities Act of 1933, each post-effective amendment that contains a form of prospectus shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

&nbsp;&nbsp;&nbsp;&nbsp;(3) For the purpose of determining liability under the Securities Act to any purchaser, if the registrant is subject to Rule 430C, each prospectus filed pursuant to Rule 424(b) as part of a registration statement relating to an offering, other than registration statements relying on Rule 430B or other than prospectuses filed in reliance on Rule 430A, shall be deemed to be part of and included in the registration statement as of the date it is first used after effectiveness. Provided, however, that no statement made in a registration statement or prospectus that is part of the registration statement or made in a document incorporated or deemed incorporated by reference into the registration statement or prospectus that is part of the registration statement will, as to a purchaser with a time of contract of sale prior to such first use, supersede or modify any statement that was made in the registration statement or prospectus that was part of the registration statement or made in any such document immediately prior to such date of first use.

&nbsp;&nbsp;&nbsp;&nbsp;(4) For the purpose of determining liability of a registrant under the Securities Act to any purchaser in the initial distribution of the securities, the undersigned registrant undertakes that in a primary offering of securities of an undersigned registrant pursuant to this registration statement, regardless of the underwriting method used to sell the securities to the purchaser, if the securities are offered or sold to such purchaser by means of any of the following communications, the undersigned registrant will be a seller to the purchaser and will be considered to offer or sell such securities to such purchaser.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;i. Any preliminary prospectus or prospectus of the undersigned registrant relating to the offering required to be filed pursuant to Rule 424;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;ii. Any free writing prospectus relating to the offering prepared by or on behalf of the undersigned registrant or used or referred to by an undersigned registrant;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;iii. The portion of any other free writing prospectus relating to the offering containing material information about the undersigned registrant or its securities provided by or on behalf of the undersigned registrant; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;iv. Any other communication that is an offer in the offering made by the undersigned registrant to the purchaser.
